    The NTF-like family of transcription factors have been implicated in developmental regulation in organisms as diverse as Drosophila and man. The two mammalian members of this family, CP2 (LBP-1c/LSF) and LBP-1a (NF2d9), are highly related proteins sharing an overall amino acid identity of 72%. CP2, the best characterized of these factors, is a ubiquitously expressed 66-kDa protein that binds the regulatory regions of many diverse genes. Consequently, a role for CP2 has been proposed in globin gene expression, T-cell responses to mitogenic stimulation, and several other cellular processes. To elucidate the in vivo role of CP2, we have generated mice nullizygous for the CP2 allele. These animals were born in a normal Mendelian distribution and displayed no defects in growth, behavior, fertility, or development. Specifically, no perturbation of hematopoietic differentiation, globin gene expression, or immunological responses to T- and B-cell mitogenic stimulation was observed. RNA and protein analysis confirmed that the nullizygous mice expressed no full-length or truncated version of CP2. Electrophoretic mobility shift assays with nuclear extracts from multiple tissues demonstrated loss of CP2 DNA binding activity in the -/- lines. However, a slower migrating complex that was ablated with antiserum to NF2d9, the murine homologue of LBP-1a, was observed with these extracts. Furthermore, we demonstrate that recombinant LBP-1a can bind to known CP2 consensus sites and form protein complexes with previously defined heteromeric partners of CP2. These results suggest that LBP-1a/NF2d9 may compensate for loss of CP2 expression in vivo and that further analysis of the role of the NTF family of proteins requires the targeting of the NF2d9 gene.

    For the first time new treatments in melanoma have produced significant responses in advanced diseases, but 30–90% of melanoma patients do not respond or eventually relapse after the initial response to the current treatments. The resistance of these melanomas is likely due to tumor heterogeneity, which may be explained by models such as the stochastic, hierarchical, and phenotype-switching models. This review will discuss the recent advancements in targeting BCL-2 family members for cancer t...

  3. Targeting GSK-3 family members in the heart: a very sharp double-edged sword.

    The GSK-3 family of serine/threonine kinases, which is comprised of two isoforms (α and β), was initially identified as a negative regulator of glycogen synthase, the rate limiting enzyme of glycogen synthesis [1,2]. In the 30 years since its initial discovery, the family has been reported to regulate a host of additional cellular processes and, consequently, disease states such as bipolar disorders, diabetes, inflammatory diseases, cancer, and neurodegenerative diseases including Alzheimer's Disease and Parkinson's Disease [3,4]. As a result, there has been intense interest on the part of the pharmaceutical industry in developing small molecule antagonists of GSK-3. Herein, we will review the roles played by GSK-3s in the heart, focusing primarily on recent studies that have employed global and tissue-specific gene deletion. We will highlight roles in various pathologic processes, including pressure overload and ischemic injury, focusing on some striking isoform-specific effects of the family. Due to space limitations and/or the relatively limited data in gene-targeted mice, we will not be addressing the family's roles in ischemic pre-conditioning or its many interactions with various pro- and anti-apoptotic factors.

  6. Identification of Targets of CUG-BP, Elav-Like Family Member 1 (CELF1 Regulation in Embryonic Heart Muscle.

    Full Text Available CUG-BP, Elav-like family member 1 (CELF1 is a highly conserved RNA binding protein that regulates pre-mRNA alternative splicing, polyadenylation, mRNA stability, and translation. In the heart, CELF1 is expressed in the myocardium, where its levels are tightly regulated during development. CELF1 levels peak in the heart during embryogenesis, and aberrant up-regulation of CELF1 in the adult heart has been implicated in cardiac pathogenesis in myotonic dystrophy type 1, as well as in diabetic cardiomyopathy. Either inhibition of CELF activity or over-expression of CELF1 in heart muscle causes cardiomyopathy in transgenic mice. Nonetheless, many of the cardiac targets of CELF1 regulation remain unknown. In this study, to identify cardiac targets of CELF1 we performed cross-linking immunoprecipitation (CLIP for CELF1 from embryonic day 8 chicken hearts. We identified a previously unannotated exon in MYH7B as a novel target of CELF1-mediated regulation. We demonstrated that knockdown of CELF1 in primary chicken embryonic cardiomyocytes leads to increased inclusion of this exon and decreased MYH7B levels. We also investigated global changes in the transcriptome of primary embryonic cardiomyocytes following CELF1 knockdown in a published RNA-seq dataset. Pathway and network analyses identified strong associations between CELF1 and regulation of cell cycle and translation. Important regulatory proteins, including both RNA binding proteins and a cardiac transcription factor, were affected by loss of CELF1. Together, these data suggest that CELF1 is a key regulator of cardiomyocyte gene expression.

    The analysis of phenotypic change resulting from gene disruption following homologous recombination provides a powerful technique for the study of gene function. This technique has so far been difficult to apply to plants because the frequency of gene disruption following transformation with constructs containing DNA homologous to genomic sequences is low (0.01 to 0.1%). It has recently been shown that high rates of gene disruption (up to 90%) can be achieved in the moss Physcomitrella patens using genomic sequences of unknown function. We have used this system to examine the specificity of gene disruption in Physcomitrella using a member of the Cab multigene family. We have employed the previously characterised Cab gene ZLAB1 and have isolated segments of 13 other closely related members of the Cab gene family. In the 199-bp stretch sequenced, the 13 new members of the Cab family show an average of 8.5% divergence from the DNA sequence of ZLAB1. We observed 304 silent substitutions and 16 substitutions that lead to a change in the amino acid sequence of the protein. We cloned 1029 bp of the coding region of ZLAB1 (including 177 of the 199 bp with high homology to the 13 new Cab genes) into a vector containing a selectable hygromycin resistance marker, and used this construct to transform P. patens. In three of nine stable transformants tested, the construct had inserted in, and disrupted, the ZLAB1 gene. There was no discernible phenotype associated with the disruption. We have therefore shown that gene disruption is reproducible in P. patens and that the requirement for sequence homology appears to be stringent, therefore allowing the role of individual members of a gene family to be analysed in land plants for the first time.

    The function of p53 is best understood in response to genotoxic stress, but increasing evidence suggests that p53 also plays a key role in the regulation of metabolic homeostasis. p53 and its family members directly influence various metabolic pathways, enabling cells to respond to metabolic stress. These functions are likely to be important for restraining the development of cancer but could also have a profound effect on the development of metabolic diseases, including diabetes. A better understanding of the metabolic functions of p53 family members may aid in the identification of therapeutic targets and reveal novel uses for p53-modulating drugs.

    Full Text Available Objective: The purpose of this study was to determine the bacterial contamination of toothbrushes in family members. Materials and Methods: One hundred and two healthy subjects were included in this descriptive study. Every individual was examined clinically and microbiologically using the CPITN index and collecting subgingival plaque samples. Each participant received a toothbrush for home use and after one month they returned it to the investigators. All toothbrushes were cultured to determine the presence of periodontopathic bacteria and enteric rods. Wilkoxon signed rank test and t student test (P d"0.05 were used to compare differences in the subgingival microbiota and toothbrush contamination and CPITN index among family members. Results: A high proportion of toothbrushes resulted highly contaminated with enteric rods (P d"0.001 compared to the subgingival environment where periodontopathic bacteria were more prevalent. The most frequent microorganisms found in toothbrushes used by parents and children for one month were Enterobacteriaceae, Pseudomonadaceae species (>50% and Fusobacterium spp (30%. Conclusions: High levels of enteric rods were commonly detected in toothbrushes used for 1 month among members of the families. These opportunistic organisms may have an important role in oral infections including gingivitis and periodontitis. Monthly replacement or disinfection of the toothbrush can reduce the risk of bacterial transmission/translocation and thus diminish the incidence of biofilm associated oral diseases.

    Full Text Available Alzheimer's disease (AD is a multifactorial, fatal neurodegenerative disorder characterized by the abnormal accumulation of Aβ and Tau deposits in the brain. There is no cure for AD, and failure at different clinical trials emphasizes the need for new treatments. In recent years, significant progress has been made toward the development of miRNA-based therapeutics for human disorders. This study was designed to evaluate the efficiency and potential safety of miRNA replacement therapy in AD, using miR-15/107 paralogues as candidate drug targets. We identified miR-16 as a potent inhibitor of amyloid precursor protein (APP and BACE1 expression, Aβ peptide production, and Tau phosphorylation in cells. Brain delivery of miR-16 mimics in mice resulted in a reduction of AD-related genes APP, BACE1, and Tau in a region-dependent manner. We further identified Nicastrin, a γ-secretase component involved in Aβ generation, as a target of miR-16. Proteomics analysis identified a number of additional putative miR-16 targets in vivo, including α-Synuclein and Transferrin receptor 1. Top-ranking biological networks associated with miR-16 delivery included AD and oxidative stress. Collectively, our data suggest that miR-16 is a good candidate for future drug development by targeting simultaneously endogenous regulators of AD biomarkers (i.e., Aβ and Tau, inflammation, and oxidative stress.

    Thrombogenic and inflammatory mediators, such as thrombin, induce NF-κB-mediated endothelial cell (EC) activation and dysfunction, which contribute to pathogenesis of arterial thrombosis. The role of anti-inflammatory microRNA-181b (miR-181b) on thrombosis remains unknown. Our previous study demonstrated that miR-181b inhibits downstream NF-κB signaling in response to TNF-α. Here, we demonstrate that miR-181b uniquely inhibits upstream NF-κB signaling in response to thrombin. Overexpression of miR-181b inhibited thrombin-induced activation of NF-κB signaling, demonstrated by reduction of phospho-IKK-β, -IκB-α, and p65 nuclear translocation in ECs. MiR-181b also reduced expression of NF-κB target genes VCAM-1, intercellular adhesion molecule-1, E-selectin, and tissue factor. Mechanistically, miR-181b targets caspase recruitment domain family member 10 (Card10), an adaptor protein that participates in activation of the IKK complex in response to signals transduced from protease-activated receptor-1. miR-181b reduced expression of Card10 mRNA and protein, but not protease-activated receptor-1. 3'-Untranslated region reporter assays, argonaute-2 microribonucleoprotein immunoprecipitation studies, and Card10 rescue studies revealed that Card10 is a bona fide direct miR-181b target. Small interfering RNA-mediated knockdown of Card10 expression phenocopied effects of miR-181b on NF-κB signaling and targets. Card10 deficiency did not affect TNF-α-induced activation of NF-κB signaling, which suggested stimulus-specific regulation of NF-κB signaling and endothelial responses by miR-181b in ECs. Finally, in response to photochemical injury-induced arterial thrombosis, systemic delivery of miR-181b reduced thrombus formation by 73% in carotid arteries and prolonged time to occlusion by 1.6-fold, effects recapitulated by Card10 small interfering RNA. These data demonstrate that miR-181b and Card10 are important regulators of thrombin-induced EC activation and

  14. The Salmonella Effector Protein SopA Modulates Innate Immune Responses by Targeting TRIM E3 Ligase Family Members.

    Full Text Available Salmonella Typhimurium stimulates inflammatory responses in the intestinal epithelium, which are essential for its ability to replicate within the intestinal tract. Stimulation of these responses is strictly dependent on the activity of a type III secretion system encoded within its pathogenicity island 1, which through the delivery of effector proteins, triggers signaling pathways leading to inflammation. One of these effectors is SopA, a HECT-type E3 ligase, which is required for the efficient stimulation of inflammation in an animal model of Salmonella Typhimurium infection. We show here that SopA contributes to the stimulation of innate immune responses by targeting two host E3 ubiquitin ligases, TRIM56 and TRIM65. We also found that TRIM65 interacts with the innate immune receptor MDA5 enhancing its ability to stimulate interferon-β signaling. Therefore, by targeting TRIM56 and TRIM65, SopA can stimulate signaling through two innate immune receptors, RIG-I and MDA5. These findings describe a Salmonella mechanism to modulate inflammatory responses by directly targeting innate immune signaling mechanisms.

  15. AtSIG6 and other members of the sigma gene family jointly but differentially determine plastid target gene expression in Arabidopsis thaliana

    Full Text Available Plants contain a nuclear gene family for plastid sigma factors, i.e. proteins that associate with the bacterial-type organellar RNA polymerase and confer the ability for correct promoter binding and transcription initiation. Questions that are still unresolved relate to the division of labour among members of the sigma family, both in terms of their range of target genes and their temporal and spatial activity during development. Clues to the in vivo role of individual sigma genes have mainly come from studies of sigma knockout lines. Despite its obvious strengths, however, this strategy does not necessarily trace-down causal relationships between mutant phenotype and a single sigma gene, if other family members act in a redundant and/or compensatory manner. We made efforts to reduce the complexity by genetic crosses of Arabidopsis single mutants (with focus on a chlorophyll-deficient sig6 line to generate double knockout lines. The latter typically had a similar visible phenotype as the parental lines, but tended to be more strongly affected in the transcript patterns of both plastid and sigma genes. Because triple mutants were lethal under our growth conditions, we exploited a strategy of transformation of single and double mutants with RNAi constructs that contained sequences from the unconserved sigma region (UCR. These RNAi/knockout lines phenotypically resembled their parental lines, but were even more strongly affected in their plastid transcript patterns. Expression patterns of sigma genes revealed both similarities and differences compared to the parental lines, with transcripts at reduced or unchanged amounts and others that were found to be present in higher (perhaps compensatory amounts. Together, our results reveal considerable flexibility of gene activity at the levels of both sigma and plastid gene expression. A (still viable basal state seems to be reached, if 2 - 3 of the 6 Arabidopsis sigma genes are functionally compromised.

    Plants contain a nuclear gene family for plastid sigma factors, i.e., proteins that associate with the "bacterial-type" organellar RNA polymerase and confer the ability for correct promoter binding and transcription initiation.

    A novel conotoxin, named as PiVIIA, was isolated from the venom of Conus princeps, a marine predatory cone snail collected in the Pacific Southern Coast of Mexico. Chymotryptic digest of the S-alkylated peptide in combination with liquid chromatography coupled to tandem mass spectrometry, were used to define the sequencing of this peptide. Eleven N-terminal amino acids were verified by automated Edman degradation. PiVIIA is a 25-mer peptide (CDAOTHYCTNYWγCCSGYCγHSHCW) with six cysteine residues forming three disulphide bonds, a hydroxyproline (O) and two gamma carboxyglutamic acid (γ) residues. Based on the arrangement of six Cys residues (C-C-CC-C-C), this conotoxin might belong to the O2-superfamily. Moreover, PiVIIA has a conserved motif (-γCCS-) that characterizes γ-conotoxins from molluscivorous Conus. Peptide PiVIIA has 45% sequence identity with γ-PnVIIA—the prototype of this family. Biological activity of PiVIIA was assessed by voltage-clamp recording in rat dorsal root ganglion neurons. Perfusion of PiVIIA in the µM range produces a significant increase in the Ca2+ currents, without significantly modifying the Na+, K+ or proton-gated acid sensing ionic currents. These results indicate that PiVIIA is a new conotoxin whose activity deserves further studies to define its potential use as a positive modulator of neuronal activity. PMID:26861393

    The common γ molecule (γc) is a shared signaling receptor subunit used by six γc-cytokines. These cytokines play crucial roles in the differentiation of the mature immune system and are involved in many human diseases. Moreover, recent studies suggest that multiple γc-cytokines are pathogenically involved in a single disease, thus making the shared γc-molecule a logical target for therapeutic intervention. However, the current therapeutic strategies seem to lack options to treat such cases, partly because of the lack of appropriate neutralizing antibodies recognizing the γc and, more importantly, because of the inherent and practical limitations in the use of monoclonal antibodies. By targeting the binding interface of the γc and cytokines, we successfully designed peptides that not only inhibit multiple γc-cytokines but with a selectable target spectrum. Notably, the lead peptide inhibited three γc-cytokines without affecting the other three or non-γc-cytokines. Biological and mutational analyses of our peptide provide new insights to our current understanding on the structural aspect of the binding of γc-cytokines the γc-molecule. Furthermore, we provide evidence that our peptide, when conjugated to polyethylene glycol to gain stability in vivo, efficiently blocks the action of one of the target cytokines in animal models. Collectively, our technology can be expanded to target various combinations of γc-cytokines and thereby will provide a novel strategy to the current anti-cytokine therapies against immune, inflammatory, and malignant diseases.

  1. Clinical profiling of BCL-2 family members in the setting of BRAF inhibition offers a rationale for targeting de novo resistance using BH3 mimetics.

    Directory of Open Access Journals (Sweden)

    Dennie T Frederick

    Full Text Available While response rates to BRAF inhibitiors (BRAFi are high, disease progression emerges quickly. One strategy to delay the onset of resistance is to target anti-apoptotic proteins such as BCL-2, known to be associated with a poor prognosis. We analyzed BCL-2 family member expression levels of 34 samples from 17 patients collected before and 10 to 14 days after treatment initiation with either vemurafenib or dabrafenib/trametinib combination. The observed changes in mRNA and protein levels with BRAFi treatment led us to hypothesize that combining BRAFi with a BCL-2 inhibitor (the BH3-mimetic navitoclax would improve outcome. We tested this hypothesis in cell lines and in mice. Pretreatment mRNA levels of BCL-2 negatively correlated with maximal tumor regression. Early increases in mRNA levels were seen in BIM, BCL-XL, BID and BCL2-W, as were decreases in MCL-1 and BCL2A. No significant changes were observed with BCL-2. Using reverse phase protein array (RPPA, significant increases in protein levels were found in BIM and BID. No changes in mRNA or protein correlated with response. Concurrent BRAF (PLX4720 and BCL2 (navitoclax inhibition synergistically reduced viability in BRAF mutant cell lines and correlated with down-modulation of MCL-1 and BIM induction after PLX4720 treatment. In xenograft models, navitoclax enhanced the efficacy of PLX4720. The combination of a selective BRAF inhibitor with a BH3-mimetic promises to be an important therapeutic strategy capable of enhancing the clinical efficacy of BRAF inhibition in many patients that might otherwise succumb quickly to de novo resistance.

    The complex family environments in which a suicide death had previously occurred were explored in a qualitative study of narratives of suicide-bereaved participants. The participants searched for reasons why the suicide occurred in their family. Family patterning stories and the context of the environment in which the suicide death occurred provided an additional depth of meaning into the relational aspects of the family. Fractured families emerged as an important theme. Shared in the narratives were stories of conditions within the family that may have contributed to vulnerability towards persistent negative feelings about their lives, their family, and their future. The study also identifies the strengths of family culture that led to resilience in the suicide bereaved. These stories highlight the importance of support for those bereaved by the suicide of a close family member and the issues that places people in vulnerable situations that perhaps may explain the increased risk of suicide for those bereaved family members.

    Characterize the process of family vegetable selection (especially cruciferous, deep orange, and dark green leafy vegetables); demonstrate the usefulness of Exchange Theory (how family norms and experiences interact with rewards and costs) for interpreting the data. Eight focus groups, 2 with each segment (men/women vegetable likers/dislikers based on a screening form). Participants completed a vegetable intake form. Rural Appalachian Pennsylvania. Sixty-one low-income, married/cohabiting men (n = 28) and women (n = 33). Thematic analysis within Exchange Theory framework for qualitative data. Descriptive analysis, t tests and chi-square tests for quantitative data. Exchange Theory proved useful for understanding that regardless of sex or vegetable liker/disliker status, meal preparers see more costs than rewards to serving vegetables. Experience plus expectations of food preparer role and of deference to family member preferences supported a family norm of serving only vegetables acceptable to everyone. Emphasized vegetables are largely ignored because of unfamiliarity; family norms prevented experimentation and learning through exposure. Interventions to increase vegetable consumption of this audience could (1) alter family norms about vegetables served, (2) change perceptions of experiences, (3) reduce social and personal costs of serving vegetables, and (4) increase tangible and social rewards of serving vegetables.

    The CELLULOSESYNTHASE-LIKE C(CSLC) family is an ancient lineage within the CELLULOSE SYNTHASE/CEL-LULOSE SYNTHASE-LIKE (CESA/CSL) polysaccharide synthase superfamily that is thought to have arisen before the diver-gence of mosses and vascular plants. As studies in the flowering plant Arabidopsis have suggested synthesis of the (1,4)-β-glucan backbone of xyloglucan (XyG), a wall polysaccharide that tethers adjacent cellulose microfibrils to each other, as a probable function for the CSLCs, CSLC function was investigated in barley (Hordeum vulgare L.), a species with low amounts of XyG in its walls. Four barley CSLC genes were identified (designated HvCSLC1-4). Phylogenetic analysis reveals three well supported clades of CSLCs in flowering plants, with barley having representatives in two of these clades. The four barley CSLCs were expressed in various tissues, with in situ PCR detecting transcripts in all cell types of the coleoptile and root, including cells with primary and secondary cell walls. Co-expression analysis showed that HvCSLC3 was coor-dinately expressed with putative XyG xylosyltransferase genes. Both immuno-EM and membrane fractionation showed that HvCSLC2 was located in the plasma membrane of barley suspension-cultured cells and was not in internal membranes such as endoplasmic reticulum or Golgi apparatus. Based on our current knowledge of the sub-cellular locations of poly-saccharide synthesis, we conclude that the CSLC family probably contains more than one type of polysaccharide synthase.

    Full Text Available This exploratory research paper investigated the coping strategies of families of hospitalized psychiatric patients and identified their positive and negative coping strategies. In this paper, the coping strategies of 45 family members were examined using a descriptive, correlational, mixed method research approach. Guided by the Neuman Systems Model and using the Family Crisis Oriented Personal Evaluation Scales and semistructured interviews, this paper found that these family members used more emotion-focused coping strategies than problem-focused coping strategies. The common coping strategies used by family members were communicating with immediate family, acceptance of their situation, passive appraisal, avoidance, and spirituality. The family members also utilized resources and support systems, such as their immediate families, mental health care professionals, and their churches.

    Research has documented numerous benefits and challenges associated with receipt of hospice care in nursing homes; however, study of this partnership from the perspective of residents' family members has been limited. The purpose of this qualitative investigation was to explore family members' experience with hospice services received in the nursing home setting. Researchers conducted a secondary data analysis of 175 family member interviews using a thematic analytic approach. Findings highlighted the critical role of communication in supporting residents and their family members. Care coordination, support and oversight, and role confusion also impacted family members' experience of hospice care in the nursing home. Efforts directed at enhancing communication and more clearly articulating the roles of members of the health care team are indicated.

    The Forkhead transcription factor FOXP2 is implicated in speech perception and production. The avian homolog, FoxP2 contributes to song learning and production in birds. In human cell lines, transcriptional activity of FOXP2 requires homo-dimerization or dimerization with paralogs FOXP1 or FOXP4. Whether FoxP dimerization occurs in the brain is unknown. We recently showed that FoxP1, FoxP2 and FoxP4 (FoxP1/2/4) proteins are co-expressed in neurons of Area X, a song control region in zebra finches. We now report on dimer- and oligomerization of zebra finch FoxPs and how this affects transcription. In cell lines and in the brain we identify homo- and hetero-dimers, and an oligomer composed of FoxP1/2/4. We further show that FoxP1/2 but not FoxP4 bind to the regulatory region of the target gene Contactin-associated protein-like 2 (CNTNAP2). In addition, we demonstrate that FoxP1/4 bind to the regulatory region of very low density lipoprotein receptor (VLDLR), as has been shown for FoxP2 previously. Interestingly, FoxP1/2/4 individually or in combinations regulate the promoters for SV40, zebra finch VLDLR and CNTNAP2 differentially. These data exemplify the potential for complex transcriptional regulation of FoxP1/2/4, highlighting the need for future functional studies dissecting their differential regulation in the brain.

    Purpose/Objectives To describe the impact of the cancer experience on the health behaviors of survivors’ family members and to determine factors associated with family members’ intentions for health behavior change. Design Descriptive, cross-sectional, correlational study. Setting A National Cancer Institute-designated comprehensive cancer center in the Midwestern United States. Sample 39 family members and 50 patients with diagnoses of breast, colon, head and neck, lung, or prostate cancer who were completing definitive cancer treatment. Methods Patients and family members were approached in the clinic at 3 weeks or less before the completion of their course of treatment. Family members completed surveys and a structured interview in-person or via telephone. Main Research Variables Intention, perceived benefit, and confidence for eating a healthy diet, physical activity, and smoking cessation; emotional distress; and family cohesiveness, conflict, and expressiveness. Findings Family members had, on average, high ratings for intention, perceived benefit, and confidence related to behaviors of eating a healthy diet and doing 30 minutes of daily moderate physical activity. They also had high ratings for the extent to which the cancer experience raised their awareness of their own cancer risk and made them think about having screening tests; ratings were lower for making changes in their health behaviors. Distress scores of family members were high at the completion of cancer treatment. Greater intention for physical activity and nutrition was associated with greater perceived benefit and confidence. Higher scores for family expressiveness was associated with intention for nutrition. Greater intention for smoking cessation was associated only with confidence. Conclusions Family members expressed strong intentions to engage in health-promoting behaviors related to physical activity and nutrition at the transition to post-treatment survivorship.

    To provide high-quality and effective cancer care, problems and unmet needs of family members during their relatives' hospitalisation have to be identified as well. The aims were to determine how needs of family members of patients with terminal cancer are met and to analyse factors that influence them. The needs were assessed with the Family Inventory of Needs. Each item (n = 20) represents one need of family members, for which the importance and satisfaction are rated. The study comprised 270 family members of hospitalised advanced cancer patients staying in the University Hospital Ostrava who were receiving palliative care. The family members preferred sufficient basic information and patient comfort. The unmet needs were support of hope (73%) and provision of information (65%). The unmet needs were more frequently identified by women, individuals with lower education, younger persons, unemployed, patients' children and family members of patients with generally unfavourable health status (P family members may improve their quality of life.

    Thirty-three families (71 subjects) were screened for the presence of Candida albicans in mouthwash or stool specimens; 12 families (28 subjects) were culture-positive for this yeast. An enrichment procedure provided a twofold increase in the recovery of C. albicans from mouthwash specimens. Nine of the twelve culture-positive families had two positive members each, two families had three positive members each, and one family had four positive members. Genetic profiles were obtained by three methods: pulsed-field gel electrophoresis; restriction endonuclease analysis, and random amplification of polymorphic DNA analysis. DNA fingerprinting of C. albicans isolated from one body site three consecutive times revealed that each of the 12 families carried a distinct genotype. No two families shared the same strain, and two or more members of a family commonly shared the same strain. Intrafamily genotypic identity (i.e., each member within the family harbored the same strain) was demonstrated in six families. Genotypes of isolates from husband and wife differed from one another in five families. All three methods were satisfactory in determining genotypes; however, we concluded that restriction endonuclease analysis provided adequate resolving power.

    1999-08-01

    This report documents the findings of a survey of patients who received radioactive iodine therapy and their family members. The main objective of the survey was to gain an understanding of the experience of receiving radioactive iodine from the patient and family's perspective. The data from this study helped to inform the ARCP and GMA as they developed AC-9 - Principles of the management of radionuclide therapies. A survey was distributed to 700 patients and family members through physicians at 8 sites across Canada. Locations included: Newfoundland, Nova Scotia, Ontario (2 sites), Quebec (2 sites), Manitoba and British Columbia. A total of 190 patients and 140 family members returned completed surveys. Data was analyzed separately for individuals treated as inpatients and those treated as outpatients. The results of the survey provided a perspective from patients and families about their experiences regarding radioactive iodine therapy. The data indicate variation in patients' and family members' perspectives about how precautions are to be implemented. Both patients and family members expressed the desire for more information regarding many aspects of the treatment experience. The results have implications for the development of patient information, continuing education (in particular in the areas of precaution), the provision of access to supportive and counselling services, and the importance of looking at the individual situations of patients and their families.

  11. Myocardin Family Members Drive Formation of Caveolae.

    Directory of Open Access Journals (Sweden)

    Katarzyna K Krawczyk

    Full Text Available Caveolae are membrane organelles that play roles in glucose and lipid metabolism and in vascular function. Formation of caveolae requires caveolins and cavins. The make-up of caveolae and their density is considered to reflect cell-specific transcriptional control mechanisms for caveolins and cavins, but knowledge regarding regulation of caveolae genes is incomplete. Myocardin (MYOCD and its relative MRTF-A (MKL1 are transcriptional coactivators that control genes which promote smooth muscle differentiation. MRTF-A communicates changes in actin polymerization to nuclear gene transcription. Here we tested if myocardin family proteins control biogenesis of caveolae via activation of caveolin and cavin transcription. Using human coronary artery smooth muscle cells we found that jasplakinolide and latrunculin B (LatB, substances that promote and inhibit actin polymerization, increased and decreased protein levels of caveolins and cavins, respectively. The effect of LatB was associated with reduced mRNA levels for these genes and this was replicated by the MRTF inhibitor CCG-1423 which was non-additive with LatB. Overexpression of myocardin and MRTF-A caused 5-10-fold induction of caveolins whereas cavin-1 and cavin-2 were induced 2-3-fold. PACSIN2 also increased, establishing positive regulation of caveolae genes from three families. Full regulation of CAV1 was retained in its proximal promoter. Knock down of the serum response factor (SRF, which mediates many of the effects of myocardin, decreased cavin-1 but increased caveolin-1 and -2 mRNAs. Viral transduction of myocardin increased the density of caveolae 5-fold in vitro. A decrease of CAV1 was observed concomitant with a decrease of the smooth muscle marker calponin in aortic aneurysms from mice (C57Bl/6 infused with angiotensin II. Human expression data disclosed correlations of MYOCD with CAV1 in a majority of human tissues and in the heart, correlation with MKL2 (MRTF-B was observed. The

    2012-02-01

    PURPOSE: The purpose of this study was to examine the relationship between psychological and social factors and diabetes outcomes in people with type 2 diabetes and their family members. METHODS: A total of 153 patients with type 2 diabetes were assessed at a diabetes outpatient clinic and postal questionnaires were sent to nominated family members. The measures examined were diabetes knowledge, social support, well-being, and illness perceptions. RESULTS: When compared with those with diabetes, family members reported lower positive well-being and lower levels of satisfaction with support. They also perceived diabetes as a more cyclical illness, which was controlled more by treatment than by the individual. Family members also reported that the person with diabetes was more emotionally distressed and knew more about diabetes than the patient had actually reported himself or herself. There were no differences between the family members of those in good or poor glycaemic control. CONCLUSIONS: This study reinforces the importance of understanding social context and illness beliefs in diabetes management. It also highlights the potential for including family members in discussions and education about diabetes management.

  13. Molecular cloning and characterization of NcROP2Fam-1, a member of the ROP2 family of rhoptry proteins in Neospora caninum that is targeted by antibodies neutralizing host cell invasion in vitro.

    2013-07-01

    Recent publications demonstrated that a fragment of a Neospora caninum ROP2 family member antigen represents a promising vaccine candidate. We here report on the cloning of the cDNA encoding this protein, N. caninum ROP2 family member 1 (NcROP2Fam-1), its molecular characterization and localization. The protein possesses the hallmarks of ROP2 family members and is apparently devoid of catalytic activity. NcROP2Fam-1 is synthesized as a pre-pro-protein that is matured to 2 proteins of 49 and 55 kDa that localize to rhoptry bulbs. Upon invasion the protein is associated with the nascent parasitophorous vacuole membrane (PVM), evacuoles surrounding the host cell nucleus and, in some instances, the surface of intracellular parasites. Staining was also observed within the cyst wall of 'cysts' produced in vitro. Interestingly, NcROP2Fam-1 was also detected on the surface of extracellular parasites entering the host cells and antibodies directed against NcROP2Fam-1-specific peptides partially neutralized invasion in vitro. We conclude that, in spite of the general belief that ROP2 family proteins are intracellular antigens, NcROP2Fam-1 can also be considered as an extracellular antigen, a property that should be taken into account in further experiments employing ROP2 family proteins as vaccines.

  14. Family Members' Unique Perspectives of the Family: Examining their Scope, Size, and Relations to Individual Adjustment

    2012-01-01

    Using the Family Assessment Device (FAD; Epstein, Baldwin, & Bishop, 1983) and incorporating the perspectives of adolescent, mother, and father, this study examined each family member's “unique perspective” or non-shared, idiosyncratic view of the family. To do so we used a modified multitrait-multimethod confirmatory factor analysis that (1) isolated for each family member's six reports of family dysfunction the non-shared variance (a combination of variance idiosyncratic to the individual and measurement error) from variance shared by one or more family members and (2) extracted common variance across each family member's set of non-shared variances. The sample included 128 families from a U.S. East Coast metropolitan area. Each family member's unique perspective generalized across his or her different reports of family dysfunction and accounted for a sizable proportion of his or her own variance in reports of family dysfunction. Additionally, after holding level of dysfunction constant across families and controlling for a family's shared variance (agreement regarding family dysfunction), each family member's unique perspective was associated with his or her own adjustment. Future applications and competing alternatives for what these “unique perspectives” reflect about the family are discussed. PMID:22545933

    The paper examines how family members in 18 countries attempt to influence each other to drink less. Data come from the GENACIS (Gender, Alcohol and Culture: an International Study) dataset. Countries included were Argentina, Costa Rica, Czech Republic, Denmark, Finland, Germany, Hungary, Iceland, India, Japan, Nigeria, Norway, Spain, Sri Lanka, Sweden, Uganda, UK and Uruguay (overall sample 44,115). In each country, the percentage of people who had experienced family member pressure to drink less were compared to country abstinence rate, mean drinking volume per drinker and other societal-level factors. While countries differed greatly on proportion of drinkers having experienced family members' pressure to drink less, in all countries drinking women reported less pressure than drinking men in their own society. In all studied countries, informal pressure was exerted most often by the spouse or sexual partner. However, other family members were also involved. Informal pressure was found to be highly correlated with the country's socioeconomic conditions. Informal pressure to drink less by family members is on one hand an expression of social and family problems, caused by heavy drinking, especially in the economically less developed countries, suggesting alcohol-related deprivation. On the other hand, similar gender differences were seen in all the societies, men reporting receiving more informal pressure than women. Thus, informal pressure to drink less tended to reflect the gender conflict caused by heavy use of alcohol by men.

    The therapeutic targeting of extracellular proteins is becoming hugely attractive in light of evidence implicating the tumour microenvironment as pivotal in all aspects of tumour initiation and progression. Members of the lysyl oxidase (LOX) family of proteins are secreted by tumours and are the subject of much effort to understand their roles in cancer. In this Review we discuss the roles of members of this family in the remodelling of the tumour microenvironment and their paradoxical roles in tumorigenesis and metastasis. We also discuss how targeting this family of proteins might lead to a new avenue of cancer therapeutics.

    Despite advocacy by professional nursing organizations, no randomized controlled trials (RCTs) have evaluated the response of family members to a visit with an adult patient during a postanesthesia care unit (PACU) stay. Therefore, the purpose of this RCT was to evaluate the impact of a brief PACU visitation on the anxiety of family members. The study was conducted in a phase I PACU of a large community-based hospital. Subjects were designated adult family members or significant others of an adult PACU patient who had undergone general anesthesia. A pretest-posttest RCT design was used. The dependent variable was the change in anxiety scores of the visitor after seeing his or her family member in the PACU. Student t test (unpaired, two tailed) was used to determine if changes in anxiety scores (posttest score-pretest score) were different for the PACU visit and no visit groups. A total of 45 participants were studied over a 3-month period, with N=24 randomly assigned to a PACU visit and N=21 assigned to usual care (no PACU visit). Participants in the PACU visit group had a statistically significant (P=.0001) decrease in anxiety after the visitation period (-4.11±6.4); participants in the usual care group (no PACU visit) had an increase in anxiety (+4.47±6.6). The results from this study support the value and importance of PACU visitation for family members.

    The Argonaute protein family is a highly conserved group of proteins,which have been implicated in RNA silencing in both plants and animals.Here,four members of the Argonaute family were systemically identified based on the genome sequence of Bombyx mori.Based on their sequence similarity,BmAgo1 and BmAgo2 belong to the Ago subfamily,while BmAgo3 and BmPiwi are in the Piwi subfamily.Phylogenetic analysis reveals that silkworm Argonaute family members are conserved in insects.Conserved amino acid residues involved in recognition of the 5' end of the small RNA guide strand and of the conserved(aspartate,aspartate and histidine [DDH])motif present in their PIWI domains suggest that these four Argonaute family members may have conserved slicer activities.The results of microarray expression analysis show that there is a low expression level for B.mori Argonaute family members in different tissues and different developmental stages,except for BmPiwi.All four B.mori Argonaute family members are upregulated upon infection with B.mori nucleopolyhedrovirus.The complete coding sequence of BmPiwi,the homolog of Drosophila piwi,was cloned and its expression occurred mainly in the area where spermatogonia and spermatocytes appear.Our results provide an overview of the B.mori Argonaute family members and suggest that they may have multiple roles.In addition,this is also the first report,to our knowledge,of the response of RNA silencing machinery to DNA virus infection in insects.

  19. Dynamic Expression of Novel MiRNA Candidates and MiRNA-34 Family Members in Early- to Mid-Gestational Fetal Keratinocytes Contributes to Scarless Wound Healing by Targeting the TGF-β Pathway.

    Full Text Available Early- to mid-gestational fetal mammalian skin wounds heal rapidly and without scarring. Keratinocytes (KCs have been found to exert important effects on the regulation of fibroblasts. There may be significant differences of gestational fetal KCs at different ages. The advantages in early- to mid-gestational fetal KCs could lead to fetal scarless wound healing.KCs from six human fetal skin samples were divided into two groups: a mid-gestation group (less than 28 weeks of gestational age and a late-gestation group (more than 28 weeks of gestational age. RNA extracted from KCs was used to prepare a library of small RNAs for next-generation sequencing (NGS. To uncover potential novel microRNA (miRNAs, the mirTools 2.0 web server was used to identify candidate novel human miRNAs from the NGS data. Other bioinformatical analyses were used to further validate the novel miRNAs. The expression levels of the miRNAs were further confirmed by real-time quantitative RT-PCR.A total of 61.59 million reads were mapped to 1,170 known human miRNAs in miRBase. Among a total of 202 potential novel miRNAs uncovered, 106 candidates have a higher probability of being novel human miRNAs. A total of 110 miRNAs, including 22 novel miRNA candidates, were significantly differently expressed between mid- and late-gestational fetal KCs. Thirty-three differentially expressed miRNAs and miR-34 family members are correlated with the transforming growth factor-β (TGF-β pathway.Taken together, our results provide compelling evidence supporting the existence of 106 novel miRNAs and the dynamic expression of miRNAs that extensively targets the TGF-β pathway at different gestational ages in fetal KCs. MiRNAs showing altered expression at different gestational ages in fetal KCs may contribute to scarless wound healing in early- to mid-gestational fetal KCs, and thus may be new targets for potential scar prevention and reduction therapies.

    The purpose of this study was to describe the communication issues experienced by service members staying connected with families while deployed. Qualitative design guided data collection using interviews with 20 key informants who had been deployed in Iraq or Afghanistan. Inductive content analysis and NVivo software enabled data analysis. From the data, 5 main themes emerged: Creating Normalcy Through Connecting With Others; Understanding the Spoken and Unspoken; Connecting and Disconnecting; Changing Sense of Self; and Sustaining a Common Bond. A collective understanding of common communication challenges emerged that had an impact on service member/family relationships, mission focus, and safety.

    Ricin inhibits translation by removal of a specific adenine from 28S RNA. The Ricinus communis genome encodes seven full-length ricin family members. All encoded proteins have the ability of hydrolyzing adenine in 28S rRNA. As expected, these proteins also inhibited an in vitro transcription/translation system. These data show that the ricin gene family contains at least seven members that have the ability to inhibit translation and that may contribute to the toxicity of R. communis.

    The ongoing wars in Afghanistan and Iraq have posed a number of reintegration challenges to service members. Much of the research focuses on those service members experiencing psychological problems and being treated at the VA. In this article, we contend that much of the distress service members experience occurs following deployment and is a consequence of the difficulties encountered during their efforts to successfully reintegrate into their families and communities. We propose a new conceptual framework for intervening in this reintegration distress that is psycho-educational in nature as well as a new delivery model for providing such services. An example of this new intervention framework is presented.

    Members of the TrmB family act as global transcriptional regulators for the activation or repression of sugar ABC transporters and central sugar metabolic pathways, including glycolytic, gluconeogenic, and other metabolic pathways, and also as chromosomal stabilizers in archaea. As a relatively newly classified transcriptional regulator family, there is limited experimental evidence for their role in Thermococcales, halophilic archaeon Halobacterium salinarum NRC1, and crenarchaea Sulfolobus strains, despite being one of the extending protein families in archaea. Recently, the protein structures of Pyrococcus furiosus TrmB and TrmBL2 were solved, and the transcriptomic data uncovered by microarray and ChIP-Seq were published. In the present review, recent evidence of the functional roles of TrmB family members in archaea is explained and extended to bacteria.

    The secretin family is a pleotropic group of brain-gut peptides with affinity for class 2 G-protein coupled receptors (secretin family GPCRs) proposed to have emerged early in the metazoan radiation via gene or genome duplications. In human, 10 members exist and sequence and functional homologues and ligand-receptor pairs have been characterised in representatives of most vertebrate classes. Secretin-like family GPCR homologues have also been isolated in non-vertebrate genomes however their corresponding ligands have not been convincingly identified and their evolution remains enigmatic. In silico sequence comparisons failed to retrieve a non-vertebrate (porifera, cnidaria, protostome and early deuterostome) secretin family homologue. In contrast, secretin family members were identified in lamprey, several teleosts and tetrapods and comparative studies revealed that sequence and structure is in general maintained. Sequence comparisons and phylogenetic analysis revealed that PACAP, VIP and GCG are the most highly conserved members and two major peptide subfamilies exist; i) PACAP-like which includes PACAP, PRP, VIP, PH, GHRH, SCT and ii) GCG-like which includes GCG, GLP1, GLP2 and GIP. Conserved regions flanking secretin family members were established by comparative analysis of the Takifugu, Xenopus, chicken and human genomes and gene homologues were identified in nematode, Drosophila and Ciona genomes but no gene linkage occurred. However, in Drosophila and nematode genes which flank vertebrate secretin family members were identified in the same chromosome. Receptors of the secretin-like family GPCRs are present in protostomes but no sequence homologues of the vertebrate cognate ligands have been identified. It has not been possible to determine when the ligands evolved but it seems likely that it was after the protostome-deuterostome divergence from an exon that was part of an existing gene or gene fragment by rounds of gene/genome duplication.

    2017-03-01

    This review provides an update on the new interleukin-1 (IL-1) cytokine family members in inflammatory diseases with focus on recent findings concerning the family members IL-36, IL-37, and IL-38 and their different expression patterns. The IL-1 cytokines are known to be involved in many different inflammatory and autoimmune diseases. The latest IL-1 family members, IL-36, IL-37, and IL-38 have been shown to be differently regulated during course of disease. Studies of patients suffering from inflammatory diseases revealed that those cytokines are upregulated in the serum as well as in inflamed tissue. Both, epithelial cells and infiltrating peripheral mononuclear blood cells serve as source of the cytokines IL-36, IL-37, and IL-38 triggering different outcomes. These results could be confirmed in different mouse models and in-vitro and ex-vivo studies. IL-36, IL-37, and IL-38 are involved in the pathogenesis of the inflammatory diseases psoriasis, rheumatoid arthritis, gout, systemic lupus erythematosus as well as Crohn's disease. Thereby IL-36 acts proinflammatory triggering further inflammatory mediators. In contrast, IL-37 and IL-38 are upregulated to counteract. Understanding the imbalance of the IL-1 family is crucial for future therapeutics.

    Full Text Available Innovative computer technology has sparked a revolutionary change in the area of languageanalysis. Individual researchers are increasingly likely to access huge corpora containingseveral hundred million words and to analyze the data using highly developed languageanalyzers via the Internet. Sketch Engine is one of such online language analyzers, whichregards the Internet as a data source for linguistic studies. The online system allows us toanalyze a wide range of Japanese texts with more than 400 million words, as well as texts inother languages. In this paper, we will examine the use of the words for family members inJapanese texts and reveal images of each member role hidden in the same.

  9. Insider Research with Family Members who have a Member Living with Rare Cancer

    Jan Foster PhD

    2009-12-01

    Full Text Available In this article the author explores insider research in relation to family members facing a diagnosis of rare cancer, using her experiences as one such family member undertaking doctoral research into journeys similar to hers. The “insider” issue is explored through three realms: the ethical realm, including issues of “fitness” to undertake the research; the methodological realm, including how data are obtained and used; and the trustworthiness realm, including research rigor. The exploration of her insider experiences includes personal challenges in relation to facing familiar emotionally charged experiences, insights gained as a result of her insider status, and her ability to join with participants in ways that might not be possible for an outsider. In the paper the author challenges taken-for-granted assumptions that trustworthiness can be assured only from the position of “objective” researcher. Rather, this analysis places knowledge gained through the processes and products of research as constituted and contextualized.

    Research into the role of family members in the decision making process concerning medical treatment of incompetent patients in nursing home care, shows that the involvement of a proxy decision maker implies a greater responsibility of the physician. It is the duty of the proxy decision-maker (mostly a family member) to look after the incompetent patient's interests. But it is the physician's duty to decide whether the proxy decision maker indeed fulfills this task. Even so, the physician has the professional responsibility to decide on the medical course of action. Involvement of others (relations and other health care professionals) is of great importance to the answer to the question 'What is good for this patient?' but does not absolve the physician from the obligation to decide professionally what is the right thing to do.

    The purpose of this quasi-experimental, 1-group longitudinal study is to examine the effects of a family-based intervention program on diabetes self-management behaviors, A1C, other biomarkers, psychosocial factors, and health-related quality of life in Hispanics with diabetes. Adult patients with diabetes (n = 36) and family members (n = 37) were recruited from a community clinic in rural central North Carolina. Patients and family members attended an 8-week culturally tailored diabetes educational program taught in Spanish. Data were collected pre- and post-intervention for both patients and family members, with an additional data collection for patients 1 month post-intervention. Most patients and family members were female, and almost all were immigrants. A1C decreased by 4.9% on average among patients from pre-intervention to 1 month post-intervention. Patients showed significant improvements in systolic blood pressure, diabetes self-efficacy, diabetes knowledge, and physical and mental components of health-related quality of life. Higher levels of intake of healthy foods and performance of blood glucose tests and foot inspections were reported. Family members significantly lowered body mass index and improved diabetes knowledge from pre-intervention to immediately post-intervention. No significant changes in levels of physical activity were found among patients with diabetes or family members. Findings suggest that including family members in educational interventions may provide emotional and psychological support to patients with diabetes, help to develop healthy family behaviors, and promote diabetes self-management.

    A novel subtilisin-like protein, PC8, was identified by PCR using degenerate primers to conserved amino acid residues in the catalytic region of members of the prohormone convertase family. PC8 was predicted to be 785 residues long and was structurally related to the mammalian convertases furin, PACE4, PC1 and PC2, sharing more than 50% amino acid identity over the catalytic region with these family members. PC8 possessed the catalytically important Asp, His, Asn and Ser amino acids, the homo B domain of this family of enzymes and a C-terminal hydrophobic sequence indicative of a transmembrane domain. Structurally, PC8 is more related to furin and PACE4 than to PC1 or PC2. Like furin and PACE4, PC8 mRNA was found to be widely expressed; this is in contrast with PC1 and PC2, which have a restricted distribution. Two transcripts, of 4.5 and 3.5 kb, were detected in both human cell lines and rat tissues. Unlike furin and PACE4, both of which map to chromosome 15, PC8 maps to chromosome 11q23-11q24, suggesting that this gene may have resulted from an ancient gene duplication event from either furin or PACE4, or conversely that these genes arose from PC8.

    Full Text Available Environmental mycobacteria are the causative factors of an increasing number of infections worldwide. Cutaneous infections as a result of such mycobacteria are often misdiagnosed, and their treatment is difficult since they can show in vivo and in vitro multidrug resistance. Absence of pathognomonic clinical signs and variable histological findings often delay diagnosis. We report a case of localized recurrent soft tissue swelling by Mycobacterium marinum in 2 members of the same family. The cases are being reported for their uncommon clinical presentation and the associated etiological agent. Patients recovered completely following therapy with rifampicin 600 mg plus isoniazide 300 mg daily for 45 days.

    The present study investigates the moderating effects of physical and academic self-concept on depression among children who experienced the death of a family member. Data from Phase III of the National Institute of Child Health and Human Development Study of Early Child Care was used in the present study. Having a higher physical self-concept moderated the relationship between death of a family member and depression. However, an unexpected relationship indicated that having higher math self-concept increased the probability of developing symptoms of depression. Interventions that target children's self-concept, especially physical self-concept, after a death in the family may result in fewer depression symptoms later in life.

    MicroRNA-126 (miR-126) suppresses the migration, proliferation and invasion of colon cancer cells. However, the underlying mechanisms of miR-126 in colon cancer have not been fully elucidated. In this study, in vivo experiments revealed that miR-126 inhibits colon cancer growth and metastasis. Furthermore, miR-126 was down-regulated in human colon cancer tissue, and its expression was inversely correlated with TNM stage and metastasis of patients. Low level of miR-126 identified patients with poor prognosis. And we found that miR-126 expression was negatively correlated with the expression levels of chemokine (C-X-C motif) receptor 4 (CXCR4) and components of signaling pathway of Ras homolog gene family, member A (RhoA) in vitro and in vivo. Moreover, we verified that miR-126 negatively regulated CXCR4 and RhoA signaling in vitro. In addition, either in miR-126-overexpressing or in miR- 126-silenced colon cancer cells, the restoration of CXCR4 could significantly reverse the proliferation and invasion, as well as abolish the effects of miR-126 on RhoA signaling pathway. Collectively, these results demonstrated that miR-126 acts as a tumor suppressor by inactivating RhoA signaling via CXCR4 in colon cancer. And miR-126 may serve as a prognostic marker for monitoring and treating colon cancer.

    Information and communication technologies (ICTs) are increasingly recognized as having an important role in the delivery of mental health services for youth. Recent studies have evaluated young people's access and use of technology, as well as their perspectives on using technology to receive mental health information, services, and support; however, limited attention has been given to the perspectives of family members in this regard. The aim of this study was to explore the perspectives of family members on the use of ICTs to deliver mental health services to youth within the context of specialized early intervention for a first-episode psychosis (FEP). Six focus groups were conducted with family members recruited from an early intervention program for psychosis. Twelve family members participated in the study (target sample was 12-18, and recruitment efforts took place over the duration of 1 year). A 12-item semistructured focus group guide was developed to explore past experiences of technology and recommendations for the use of technology in youth mental health service delivery. A qualitative thematic analysis guided the identification and organization of common themes and patterns identified across the dataset. Findings were organized by the following themes: access and use of technology, potential negative impacts of technology on youth in recovery, potential benefits of using technology to deliver mental health services to youth, and recommendations to use technology for (1) providing quality information in a manner that is accessible to individuals of diverse socioeconomic backgrounds, (2) facilitating communication with health care professionals and services, and (3) increasing access to peer support. To our knowledge, this is among the first (or the first) to explore the perspectives of family members of youth being treated for FEP on the use of technology for mental health care. Our results highlight the importance of considering diverse experiences

    Among a community sample of families (N = 128), this study examined how family members' shared and unique perspectives of family dysfunction relate to dyad members' shared views of dyad adjustment within adolescent-mother, adolescent-father, and mother-father dyads. Independent of a family's family perspective (shared perspective of family dysfunction), the adolescent's unique perspective was associated with lower security and higher conflict with both mother and father; the father's unique perspective was associated with lower security and higher conflict with the adolescent, as well as lower marital quality with mother; and the mother unique perspective was associated with lower marital quality with the father. Moreover, for adolescent-parent dyads, compared with the parent unique perspective, the adolescent unique perspective was more strongly associated with dyad adjustment. These findings indicate that both shared and unique views of the family system-the adolescent's unique view in particular-independently relate to the health of family subsystems. They also suggest that research, as well as therapeutic interventions, that focus on just the shared view of the family may miss important elements of family dysfunction.

    Notch signaling pathway plays an integral role in determining cell fates in development. Growing evidence demonstrates that Notch signaling pathway has versatile effects in tumorigenesis depending on the tumor type, grade and stage. Notch signaling pathway is deregulated in some brain tumors. To examine the differential expression of Notch family members (Notch1, 2, 3, 4) in human astrocytomas and medulloblastomas, and to evaluate their roles in the development of both tumor types. Immunohistochemical staining and Western blot analysis were used to detect Notch1, 2, 3, 4 expression in tissue microarray and freshly resected tissue samples of normal brain, astrocytomas and medulloblastomas. Notch family members were not expressed or barely detectable in normal brain tissues. Notch1, 3, 4 were highly expressed but Notch2 was not expressed in astrocytomas. The percentage of immunopositive tumor cells and level of Notch1 expression was increased with tumor grade. In addition, overexpression of Notch2 was detected in medulloblastomas in contrast to low or no expression of Notch1, 3, 4. Differential expression of Notch1, 2, 3, 4 is detected in astrocytomas and medulloblastomas, that may be related to their different roles playing in the development of brain tumors.

    The purpose of this study was to investigate whether plastic surgeons would perform elective cosmetic surgery on spouses or other family members and how many have done so, the type of procedures, the circumstances under which the surgery took place, and the results. Participants were 465 members of the American Society for Aesthetic Plastic Surgery, representing 30.7 percent of the overall sample pool of 1513 members recruited through anonymous, voluntary participation in an online survey. Approximately half (51.8 percent) were 51 to 65 years old, most were men (91.2 percent), and most were from large urban areas; respondents had been in practice for 1 to 40 years. The plastic surgeons who returned the survey were comfortable performing elective cosmetic procedures on family members, the majority having already done so. Eighty-eight percent reported they would operate on a spouse or other family member, and 83.9 percent reported they already had. The main motivation (67 percent) was their belief that they were the best surgeon for the procedure. The most commonly listed operations were rhinoplasty, abdominoplasty, eyelidplasty, face lift, breast augmentation, and liposuction. Patients included spouses, children, parents, cousins, and in-laws, ranging from teenaged males to women in their 70s. The overwhelming majority (94.2 percent) reported no complications, and 99.5 percent believed the patients were satisfied with their outcome. Survey participants are comfortable with the idea of performing elective cosmetic procedures on family members. Regardless of the invasiveness of the procedure or their relationship with the patient, respondents reported no complications and a high level of patient satisfaction anomalous for any patient-surgeon sample, suggesting that surgeons who operate on family members hold confident opinions of their surgical skills and results.

    The ETS family of transcription factors has been repeatedly implicated in tumorigenesis. In prostate cancer, ETS family members, such as ERG, ETV1, ETV4, and ETV5, are frequently overexpressed due to chromosomal translocations, but the molecular mechanisms by which they promote prostate tumorigenesis remain largely undefined. Here, we show that ETS family members, such as ERG and ETV1, directly repress the expression of the checkpoint kinase 1 (CHK1), a key DNA damage response cell-cycle regulator essential for the maintenance of genome integrity. Critically, we find that ERG expression correlates with CHK1 downregulation in human patients and demonstrate that Chk1 heterozygosity promotes the progression of high-grade prostatic intraepithelial neoplasia into prostatic invasive carcinoma in Pten(+) (/-) mice. Importantly, CHK1 downregulation sensitizes prostate tumor cells to etoposide but not to docetaxel treatment. Thus, we identify CHK1 as a key functional target of the ETS proto-oncogenic family with important therapeutic implications. Genetic translocation and aberrant expression of ETS family members is a common event in different types of human tumors. Here, we show that through the transcriptional repression of CHK1, ETS factors may favor DNA damage accumulation and consequent genetic instability in proliferating cells. Importantly, our findings provide a rationale for testing DNA replication inhibitor agents in ETS-positive TP53-proficient tumors. ©2015 American Association for Cancer Research.

    The family has a primary role in caring for family members who are suicidal and in the prevention of future suicide. However, the impact that suicidal behaviour has on these family members is poorly understood. To explore the lived experiences of participants who cared for suicidal family members. Eighteen participants were interviewed using a short topic guide. Responses were digitally recorded and transcripts were analysed using thematic analysis. One overarching theme: "Hard work for the whole family" and four sub-themes: (i) Family burden, (ii) competing pressures, (iii) secrecy and shame and (iv) helplessness and guilt. Caring for a suicidal family member may be euphemistically summarised as "hard work" that impacts heavily on the day-to-day tasks of other family members. Participants spent much time worrying and ruminating about the risk of suicide in their family member. Mental health care professionals ought to acknowledge and address the impact that suicidal behaviour has on family carers.

    A mixed methods study using family research with a phenomenological approach (n = 5 families) was conducted to explore family members' perceptions about the extensive monitoring technology used on their critically ill family member after cardiac surgery, as experienced when family members initially visited the patient in the cardiovascular intensive care unit. Five relevant themes emerged: overwhelmed by all of the machines; feelings of uncertainty; methods of coping; meaning of the numbers on the machines; and need for education.

    Anxiety is shared by patients and family members (FMs) and can increase throughout the FMs waiting during invasive cardiac procedures (ICP). The purpose of this study was to measure the effects of an informational report (IR) and a postprocedure visit (PPV), on the anxiety of waiting FMs. There were 151 FMs assigned to 3 groups; Group 1 (50 FMs: standard of care [SOC]), Group 2 (50 FMs: SOC + IR), and Group 3 (51 FMs: SOC + IR + PPV). Pre/ postvariables measured were: blood pressure (BP), heart rate (HR), skin temperature (ST), and anxiety. When comparing the BP, HR, ST, and anxiety there were no differences between groups with either SOC or IR. There was a significant reduction in anxiety, from baseline to the PPV in Group 3 (F = 10.1; p < .000). A PPV had an impact on FMs and a PPV should be incorporated as a nursing intervention during ICP.

    The receiving information about the patients hospitalized in the intensive care unit is classified among the most important needs of the family members of such patients. Meeting the informational needs of families is a major goal for intensive care workers. Delivering honest, intelligible and effective information raises specific challenges in the stressful setting of the intensive care unit (ICU). The aim of this qualitative study was to explain perspectives of families of Intensive Care Unit patients and nurses about informational support. Using a conventional content analysis approach, semi-structured interviews were conducted with participants to explore their perspectives of providing informational support to families of ICU patients. A purposeful sampling method was used to recruit nineteen family members of thirteen patients hospitalized in the ICU and twelve nurses from three teaching hospitals. In general, 31 persons participated in this study. Data collection continued to achieve data saturation. A conventional content analysis of the data produced three categories and seven sub-categories. The three main categories were as followed, a) providing information, b) handling information and c) using information. Providing information had three sub-categories consisting of "receiving admission news", "receiving truthful and complete information" and receiving general information. Handling information had two sub-categories consisting "keeping information" and "gradual revelation". Lastly, using information has two sub-categories consisting of "support of patient" and "support of family members". The results of this study revealed perspectives of families of Intensive Care Unit patients and nurses about informational support. It also determines the nurses' need to know more about the influence of their supportive role on family's ICU patients informing. In addition, the results of present study can be used as a basis for further studies and for offering

    Critical care nurses are often faced with working with families during the end-of-life care of a loved one. Often there is indecisiveness in family members of critically ill patients when faced with making these difficult decisions. The purpose of this manuscript is to describe origins of indecisiveness in family members of critically ill patients who are faced with end-of-life care decisions. Strategies to empower family members during this crucial time are also discussed.

    To describe and compare the quality of life (QOL) and health status of dyads of women with lung cancer and their family members and to explore the correlates of family members' QOL. Descriptive, cross-sectional. Interview, self-report. 51 dyads consisting of women with lung cancer and their family members. One-time assessment of family members' and patients' QOL, health status, and demographics and patients' clinical characteristics. Family and patient QOL and health status. QOL of the dyads was not significantly related. Poorer physical QOL of family members was associated with older age, comorbid conditions, less education, and alcohol use. Poorer emotional QOL of family members was associated with younger age, depressed mood, and not being a spouse. Fifty-nine percent of family members had comorbid conditions. Significantly more family members continued to smoke and use alcohol. The QOL of family members of patients with lung cancer is diminished when their own health status is compromised. Further study is needed. Additional study is needed to identify family members at risk for diminished QOL and with compromised health status because these factors might affect ability to support patients with lung cancer.

    Full Text Available Synaptic vesicle proteins 2 (SV2 were discovered in the early 80s, but the clear demonstration that SV2A is the target of efficacious anti-epileptic drugs from the racetam family stimulated efforts to improve understanding of its role in the brain. Many functions have been suggested for SV2 proteins including ions or neurotransmitters transport or priming of SVs. Moreover, several recent studies highlighted the link between SV2 and different neuronal disorders such as epilepsy, Schizophrenia (SCZ, Alzheimer’s or Parkinson’s disease. In this review article, we will summarize our present knowledge on SV2A function(s and its potential role(s in the pathophysiology of various brain disorders.

    Full Text Available Background: This current clinical case report highlights three cases of Hereditary angioedema (HAE patients who are all members of the same family (father and his two daughters. The father has C1–INH deficiency, while his daughters have low C1–INH levels: the first possesses only 10% function and the second has low C1–INH level with 0% function. Of note, the second daughter was discovered to have HAE at the age of 2, thus making her the youngest known HAE case report in the English literature.Methods: Assess the efficacy of administration of C1-INH before dental operation as regards the prevention of HAE episode, when total or partial C1-INH deficiency exists.Results: Acute angioedema leading to laryngeal oedema is a possibly fatal complication for HAE patients undergoing dental procedures. Use of both short-term and long-term HAE prophylaxis prior to dental operations might be life saving for those patients.Conclusions: Prevention and early recognition of potential laryngeal oedema that can occur as a complication of dental procedures may be lifesaving for HAE patients.

    2002-01-01

    This chapter reviews 73 published and unpublished research reports of interventions for family members caring for an elder with dementia by nurse researchers and researchers from other disciplines. Reports were identified through searches of MEDLINE, CINAHL, Social Science Index, PsycINFO, ERIC, Social Work Abstracts, American Association of Retired Persons database, CRISP index of the National Institutes of Health, Cochrane Center database, and Dissertation Abstracts using the following search terms: caregiver, caregiving, dementia, Alzheimer's, intervention study, evaluation study, experimental, and quasi-experimental design. Additional keywords were used to narrow or expand the search as necessary. All nursing research was included in the review and nonnursing research was included if published between 1991 and 2001. Studies were included if they used a design that included a treatment and control group or a one-group, pretest-posttest design (ex post facto designs were included if they used a comparison group). Key findings show that approximately 32% of the study outcomes (e.g., burden, depression, knowledge) were changed after intervention in the desired direction. In addition, several problematic issues were identified including small, diverse samples; lack of intervention specificity; diversity in the length, duration, and intensity of the intervention strategies; and problematic outcome measures.

  19. Regulation of p53 by ING family members in suppression of tumor initiation and progression.

    2012-06-01

    The INhibitor of Growth (ING) family is an evolutionarily conserved set of proteins, implicated in suppression of initiation and progression of cancers in various tissues. They promote cell cycle arrest, cellular senescence and apoptosis, participate in stress responses, regulate DNA replication and DNA damage responses, and inhibit cancer cell migration, invasion, and angiogenesis of the tumors. At the molecular level, ING proteins are believed to participate in chromatin remodeling and transcriptional regulation of their target genes. However, the best known function of ING proteins is their cooperation with p53 tumor suppressor protein in tumor suppression. All major isoforms of ING family members can promote the transactivition of p53 and the majority of them are shown to directly interact with p53. In addition, ING proteins are thought to interact with and modulate the function of auxiliary members of p53 pathway, such as MDM2, ARF , p300, and p21, indicating their widespread involvement in the regulation and function of this prominent tumor suppressor pathway. It seems that p53 pathway is the main mechanism by which ING proteins exert their functions. Nevertheless, regulation of other pathways which are not relevant to p53, yet important for tumorigenesis such as TGF-β and NF-κB, by ING proteins is also observed. This review summarizes the current understanding of the mutual interactions and cooperation between different members of ING family with p53 pathway and implications of this cooperation in the suppression of cancer initiation and progression.

    Renata Rego Lins Fumis

    Full Text Available INTRODUCTION: Patients and family members undergo different experiences of suffering from emotional disorders during ICU stay and after ICU discharge. The purpose of this study was to compare the incidence of anxiety, depression and post-traumatic stress disorder (PTSD symptoms in pairs (patient and respective family member, during stay at an open visit ICU and at 30 and 90-days post-ICU discharge. We hypothesized that there was a positive correlation with the severity of symptoms among pairs and different patterns of suffering over time. METHODS: A prospective study was conducted in a 22-bed adult general ICU including patients with >48 hours stay. The Hospital Anxiety and Depression Scale (HADS was completed by the pairs (patients/respective family member. Interviews were made by phone at 30 and 90-days post-ICU discharge using the Impact of Event Scale (IES and the HADS. Multivariate models were constructed to predict IES score at 30 days for patients and family members. RESULTS: Four hundred and seventy one family members and 289 patients were interviewed in the ICU forming 184 pairs for analysis. Regarding HADS score, patients presented less symptoms than family members of patients who survived and who deceased at 30 and 90-days (p<0.001. However, family members of patients who deceased scored higher anxiety and depression symptoms (p = 0.048 at 90-days when compared with family members of patients who survived. Patients and family members at 30-days had a similar IES score, but it was higher in family members at 90-days (p = 0.019. For both family members and patients, age and symptoms of anxiety and depression during ICU were the major determinants for PTSD at 30-days. CONCLUSIONS: Anxiety, depression and PTSD symptoms were higher in family members than in the patients. Furthermore, these symptoms in family members persisted at 3 months, while they decreased in patients.

    Bystander cardiopulmonary resuscitation (CPR) is a crucial therapy for sudden cardiac arrest (SCA), yet rates of bystander CPR are low. This is especially the case for SCA occurring in the home setting, as family members of at-risk patients are often not CPR trained. To evaluate the feasibility of a novel hospital-based CPR education program targeted to family members of patients at increased risk for SCA. Prospective, multicenter, cohort study. Inpatient wards at 3 hospitals. Family members of inpatients admitted with cardiac-related diagnoses. Family members were offered CPR training via a proctored video-self instruction (VSI) program. After training, CPR skills and participant perspectives regarding their training experience were assessed. Surveys were conducted one month postdischarge to measure the rate of "secondary training" of other individuals by enrolled family members. At the 3 study sites, 756 subjects were offered CPR instruction; 280 agreed to training and 136 underwent instruction using the VSI program. Of these, 78 of 136 (57%) had no previous CPR training. After training, chest compression performance was generally adequate (mean compression rate 90 ± 26/minute, mean depth 37 ± 12 mm). At 1 month, 57 of 122 (47%) of subjects performed secondary training for friends or family members, with a calculated mean of 2.1 persons trained per kit distributed. The hospital setting offers a unique "point of capture" to provide CPR instruction to an important, undertrained population in contact with at-risk individuals.

    2015-08-01

    Although military service, and particularly absence due to deployment, has been linked to risk for depression and anxiety among some spouses and children of active duty service members, there is limited research to explain the heterogeneity in family members' reactions to military service stressors. The current investigation introduces the Timeline Followback Military Family Interview (TFMFI) as a clinically useful strategy to collect detailed time-linked information about the service member's absences. Two dimensions of parent absence--the extent to which absences coincide with important family events and cumulative time absent--were tested as potential risks to family members' mental health. Data from 70 mother-adolescent pairs revealed that the number of important family events missed by the service member was linked to elevated youth symptoms of depression, even when accounting for the number of deployments and cumulative duration of the service member's absence. However, youth who reported more frequent contact with the service member during absences were buffered from the effects of extensive absence. Mothers' symptoms were associated with the cumulative duration of the service members' time away, but not with family events missed by the service member. These results identify circumstances that increase the risk for mental health symptoms associated with military family life. The TFMFI provides an interview-based strategy for clinicians wishing to understand military family members' lived experience during periods of service-member absence.

    The trypomastigote specific surface antigens of Trypanosoma cruzi are encoded by a supergene family which includes the TSA family. The TSA family is characterized by the presence of a 27-bp tandem repeat array in the coding region. Here, we report the characterization and analysis of the three TSA family members in the Esmeraldo strain of the parasite. In this strain 2 distinct telomeric members are expressed abundantly as 3.7-kb mRNAs, while the remaining member is located at an internal chromosomal site and is expressed at less than 2% of the level seen for the telomeric members. Based on hybridization to DNA separated by PFGE, 3 chromosomes of sizes 1.8 Mb, 0.98 Mb, and 0.90 Mb each contain one of the telomeric members. In addition, the two smaller chromosomes also contain the single internal member. Since both chromosomes contain similar TSA family members, and vary only slightly in size, we suggest that they are homologues. Comparisons of the nucleotide sequences of the different members of the family show that the internal gene differs from the telomeric genes primarily in sequences found 3' of the repeat array. These comparisons also reveal that the three genes are analogous, supporting the hypothesis that short segments between the family members are exchanged by gene conversion events. We propose that similar conversion events between members of different gene families may generate some of the diversity found within the supergene family.

  5. Association Between Resilience and Family Member Psychologic Symptoms in Critical Illness.

    2016-08-01

    There are increased rates of depression, anxiety, and stress disorders in families of critically ill patients. Interventions directed at family members may help their ability to cope with this stress. Specifically, resilience is a teachable psychologic construct describing a person's ability to adapt to traumatic situations. Resilience can inherently assist individuals to diminish adverse psychologic outcomes. Consequently, we determined the relationship between resilience and symptoms of depression, anxiety, and acute stress in family members of critically ill patients. This is a cross-sectional study. Three medical ICUs were screened by study staff. Family members of ICU patients admitted for greater than 48 hours were approached for enrollment. The Connor-Davidson Resilience Scale was used to stratify family members as resilient or nonresilient. The Hospital Anxiety and Depression Scale, Impact of Event Scale-Revised, and Family Satisfaction in the ICU were collected prior to ICU discharge to measure symptoms of depression, anxiety, and acute stress, as well as satisfaction with care. One-hundred and seventy family members were enrolled. Seventy-eight family members were resilient. Resilient family members had fewer symptoms of anxiety (14.2% vs 43.6%; p Resilient family members were more satisfied with care in the ICU (76.7 vs 70.8; p = 0.008). Resilience remained independently associated with these outcomes after adjusting for family member age and gender, as well as the patient's need for mechanical ventilation. When caring for the critically ill, resilient family members have fewer symptoms of depression, anxiety, and acute stress. Resilient families were generally better satisfied with the care delivered. These data suggest that interventions aimed at increasing resilience may improve a family member's experience in the ICU.

    The frequency and extent of the existence of a familial suicide prevention plan may differ across cultures. The aim of this work was, therefore, to determine how common it was for families to develop a suicide prevention plan and to compare the main measures used by families with and without such a plan, after an attempt to commit suicide was made by a member of a family living in a rural area of Korea. On the basis of the presence or absence of a familial suicide prevention plan, we compared 50 recruited families that were divided into 2 groups, with Group A (31 families) employing a familial suicide prevention plan after a suicide attempt by a family member, and Group B (19 families) not doing so. The strategy that was employed most frequently to prevent a reoccurrence among both populations was promoting communication among family members, followed by seeking psychological counseling and/or psychiatric treatment. Contrary to our expectation, the economic burden from medical treatment after a suicide attempt did not influence the establishment of a familial suicide prevention plan. It is a pressing social issue that 38% (19 of 50) of families in this study did not employ a familial suicide prevention plan, even after a family member had attempted suicide. Regional suicide prevention centers and/or health authorities should pay particular attention to these patients and their families.

    A review of the literature was conducted to explore the continuing racial disparity in capital punishment and its effects on family members of African American capital defendants. Statistical studies conducted on both the state and national level conclude that racial bias influences all stages of the death penalty process, with race of the victim being one of the most significant factors. This racial bias places an added burden on family members of African American capital defendants. While research has explored the impact of capital punishment on family members of capital defendants, the unique experiences of family members of African American defendants has not been addressed in the research literature.

    Primary prevention should be targeted at individuals with high global cardiovascular risk, but research is lacking on how best to identify such individuals in the general population. Family history is a good proxy measure of global risk and may provide an efficient mechanism for identifying high risk individuals. The aim was to test the feasibility of using patients with premature cardiovascular disease to recruit family members as a means of identifying and screening high-risk individuals. We recruited family members of 50 patients attending a cardiology clinic for premature coronary heart disease (CHD). We compared their cardiovascular risk with a general population control group, and determined their perception of their risk and current level of screening. 103 (36%) family members attended screening (27 siblings, 48 adult offspring and 28 partners). Five (5%) had prevalent CHD. A significantly higher percentage had an ASSIGN risk score >20% compared with the general population (13% versus 2%, p family members were aware they were at increased risk and only 50% had had their blood pressure and serum cholesterol level checked in the previous three years. Patients attending hospital for premature CHD provide a mechanism to contact family members and this can identify individuals with a high global risk who are not currently screened.

  14. Family members' lived experience in the intensive care unit: a phemenological study.

    McKiernan, Margaret

    2012-01-31

    AIM: To describe the lived experience of family members of patients in the intensive care unit. BACKGROUND: Admission of a critically ill relative to an intensive care unit causes anxiety and stress to family members. Nursing care is initially focused on maintaining the physiological stability of the patient and less on the needs and concerns of family members. Understanding how families make sense of this experience may help nurses focus on the delivery of family centred care. METHODOLOGY: A phenomenological method was used to describe the lived experiences of family members of patients in an intensive care unit. In-depth interviews were conducted with six family members and analysed using qualitative thematic analysis. RESULTS: Four main themes emerged from the data: the need to know, making sense of it all, being there with them and caring and support. Family members needed honest information about the patient\\'s progress and outcome to make the situation more bearable for them. Making sense of the situation was a continuous process which involved tracking and evaluating care given. Being with their relative sustained their family bond and was a way to demonstrate love and support. Caring reassurance provided by the nurses enabled a sense of security. Support was needed by family members to assist them in coping. CONCLUSION: The research provided an insight into how family members viewed the impact of the admission and how they subsequently found ways of dealing with the situation. RELEVANCE TO CLINICAL PRACTICE: Using a holistic approach to nursing assessment and care delivery in intensive care necessitates that nurses interact with and care for family members of patients. Development of a philosophy of family centred care is necessary, with formal assessment of families to take place soon after admission and an appropriate plan of care drawn up at this time.

    The purpose of this study was to preliminarily evaluate ICU family members' trust and shared decision making using modified versions of the Wake Forest Trust Survey and the Shared Decision Making-9 Survey. Using a descriptive approach, the perceptions of family members of ICU patients (n=69) of trust and shared decision making were measured using the Wake Forest Trust Survey and the 9-item Shared Decision Making (SDM-9) Questionnaire. Both surveys were modified slightly to apply to family members of ICU patients and to include perceptions of nurses as well as physicians. Overall, family members reported high levels of trust and inclusion in decision making. Family members who lived with the patient had higher levels of trust than those who did not. Family members who reported strong agreement among other family about treatment decisions had higher levels of trust and higher SDM-9 scores than those who reported less family agreement. The modified surveys may be useful in evaluating family members' trust and shared decision making in ICU settings. Future studies should include development of a comprehensive patient-centered care framework that focuses on its central goal of maintaining provider-patient/family partnerships as an avenue toward effective shared decision making.

    Introduction Patients and family members undergo different experiences of suffering from emotional disorders during ICU stay and after ICU discharge. The purpose of this study was to compare the incidence of anxiety, depression and post-traumatic stress disorder (PTSD) symptoms in pairs (patient and respective family member), during stay at an open visit ICU and at 30 and 90-days post-ICU discharge. We hypothesized that there was a positive correlation with the severity of symptoms among pairs and different patterns of suffering over time. Methods A prospective study was conducted in a 22-bed adult general ICU including patients with >48 hours stay. The Hospital Anxiety and Depression Scale (HADS) was completed by the pairs (patients/respective family member). Interviews were made by phone at 30 and 90-days post-ICU discharge using the Impact of Event Scale (IES) and the HADS. Multivariate models were constructed to predict IES score at 30 days for patients and family members. Results Four hundred and seventy one family members and 289 patients were interviewed in the ICU forming 184 pairs for analysis. Regarding HADS score, patients presented less symptoms than family members of patients who survived and who deceased at 30 and 90-days (pICU were the major determinants for PTSD at 30-days. Conclusions Anxiety, depression and PTSD symptoms were higher in family members than in the patients. Furthermore, these symptoms in family members persisted at 3 months, while they decreased in patients. PMID:25616059

    Deployment affects not just the service members, but also their family members back home. Accordingly, this study examined how resilient family processes during a deployment (i.e., frequency of communication and household management) were related to the personal reintegration of each family member (i.e., how well each family member begins to "feel like oneself again" after a deployment), as well as several indicators of subjective well-being. Drawing from the family attachment network model (Riggs & Riggs, 2011), the present study collected survey data from 273 service members, their partners, and their adolescent children. Resilient family processes during the deployment itself (i.e., frequency of communication, household management), postdeployment positive and negative personal reintegration, and several indicators of well-being were assessed. Frequency of communication was related to personal reintegration for service members, while household management was related to personal reintegration for nondeployed partners; both factors were related to personal reintegration for adolescents. Negative and positive personal reintegration related to a variety of subjective well-being outcomes for each individual family member. Interindividual (i.e., crossover) effects were also found, particularly between adolescents and nondeployed partners. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    In this descriptive study guided by the Lazarus and Folkman (1984) stress and coping theory, donor family members' emotional responses and coping strategies used during the anticipation and confrontation stages of the organ donation experience were explored. Seven families from Eastern Canada who had lost a loved one suddenly and consented to organ donation were interviewed in their homes. The findings clearly showed that family members experienced a variety of emotions and used several different types of coping strategies. The findings of this study contribute to the development of knowledge required to guide nursing interventions to provide sensitive care to family members of organ donors.

    Objective: Parenting through the deployment cycle presents unique stressors for military families. To date, few evidence-based and military-specific parenting programs are available to support parenting through cycles of deployment separation and reintegration, especially for National Guard/Reserve members. The purpose of this research was to test the efficacy of a parenting program developed specifically to support military families during reintegration. Method: Within 1 year of returning from deployment to Afghanistan or Iraq, 115 service members with very young children were randomly assigned to receive either the Strong Families Strong Forces Parenting Program at baseline or after a 12-week waiting period. Using a home-based modality, service members, at-home parents, and their young child were assessed at baseline, 3 months posttreatment/wait period, and 6 months from baseline. Results: Service member parents in Strong Families evidenced greater reductions in parenting stress and mental health distress relative to those in the waitlist comparison group. Service members with more posttraumatic stress symptoms reported higher levels of perceived parental efficacy in the intervention group than service members in the comparison group. Intervention also resulted in enhanced parental reflective capacity, including increased curiosity and interest in the young child among those in the intervention group relative to comparison. Conclusion: Service member parents and their spouses demonstrated high interest in participating in a postdeployment parenting program targeting families with very young children. Findings point to the feasibility, appeal, and efficacy of Strong Families in this initial trial and suggest promise for implementation in broader military and community service systems.

    The objective of this study was to better understand the experiences of family members in the nursing home to hospital transfer decision making process. Semi-structured interviews were conducted with 20 family members who had recently been involved in a nursing home to hospital transfer decision. Family members perceived themselves to play an advocacy role in their resident's care and interview themes clustered within three over-arching categories: Family perception of the nursing home's capacity to provide medical care: Resident and family choices; and issues at 'hand-off' and the hospital. Multiple sub-themes were also identified. Findings from this study contribute to knowledge surrounding the nursing home transfer decision by illuminating the experiences of family members in the transfer decision process.

    2015-02-01

    This study aimed to investigate family members' involvement in audiology rehabilitation appointments. Audiology appointments were video-recorded and analysed using quantitative coding and conversation analysis (CA). The study sample included 13 audiologists, 17 older adults with hearing impairment, and 17 family members. Initial coding showed that family members participated in 12% of the total talk time during audiology appointments. The CA results demonstrated that family members were not typically invited to join the conversation. However, family members would self-select to speak by: (1) responding to questions from the audiologist which were directed at the client; (2) self-initiating expansions on clients' turns; and (3) self-initiating questions. When family members did participate in the interaction, audiologists typically responded by shifting the conversation back to the client. While family members currently have minimal participation in audiology appointments, they display a strong interest in being involved and sharing their experiences of the client's hearing impairment. The findings suggest support for implementing family-centred care principles in audiology practice.

    Full Text Available Family members of patients with schizophrenia have enormous roles in the care of their patients, which could negatively impact their well being. Development of interventions targeted at alleviating the burden of informal care giving is hinged on the recognition of the factors associated with the various dimensions of burden. This study determined the correlates of caregiver burden among family members of patients with schizophrenia in Lagos, Nigeria. The study instruments included the Zarit burden interview (ZBI and the positive and negative syndrome scale for schizophrenia (PANSS. Exploratory factor analysis of the ZBI produced a five-factor structure with “financial/physical strain”, “time/dependence strain”, “emotional strain”, “uncertainty”, and “self-criticism” domains. On multiple regression analyses, total PANSS scores, poor social support, and lower educational levels of caregivers were predictive of higher burden scores on the “financial/physical strain”, “time/dependence”, and “emotional strain” domains. Longer duration of illness, shorter patient-caregiver contact time, and being a female caregiver were predictive of higher burden scores on the “uncertainty”, “self-criticism”, and “emotional strain” domains, respectively. There is need for interventions to alleviate the burden on caregivers of patients with schizophrenia in Nigeria. These strategies must include comprehensive social support and improve access to services for patients and their caregivers.

    Full Text Available C-terminal binding proteins (CtBPs are well-characterized nuclear transcriptional co-regulators. In addition, cytoplasmic functions were discovered for these ubiquitously expressed proteins. These include the involvement of the isoform CtBP1-S/BARS50 in cellular membrane-trafficking processes and a role of the isoform RIBEYE as molecular scaffolds in ribbons, the presynaptic specializations of sensory synapses. CtBPs were suggested to regulate neuronal differentiation and they were implied in the control of gene expression during epileptogenesis. However, the expression patterns of CtBP family members in specific brain areas and their subcellular localizations in neurons in situ are largely unknown. Here, we performed comprehensive assessment of the expression of CtBP1 and CtBP2 in mouse brain at the microscopic and the ultra-structural levels using specific antibodies. We quantified and compared expression levels of both CtBPs in biochemically isolated brain fractions containing cellular nuclei or synaptic compartment. Our study demonstrates differential regional and subcellular expression patterns for the two CtBP family members in brain and reveals a previously unknown synaptic localization for CtBP2 in particular brain regions. Finally, we propose a mechanism of differential synapto-nuclear targeting of its splice variants CtBP2-S and CtBP2-L in neurons.

    Epilepsy is not only a neurological disorder but may also have negative psychosocial consequences on people with epilepsy (PWE) and their relatives. Epilepsy has a major impact on quality of life (QoL) in PWE and family members. However, less is known about the impact of family support and family functioning on quality of life for PWE and family members and their interaction. Therefore, the study aimed to investigate factors that influence QoL in hospitalized adult patients with epilepsy and their relatives. An explorative cross-sectional study has been conducted in a tertiary clinic in Switzerland. Hospitalized adult patients with epilepsy and their relatives were enrolled in the study. Subjective QoL as well as family support and family functioning were measured with patients and family members. Patients and their relatives assessed the patients' support need and their satisfaction with the care provided. In addition, patients were administered a disease-related HRQoL measure (QoLIED-36, Version 2). Backward stepwise multivariate linear regression analysis was used to explain variances in patients and relatives' subjective QoL. One hundred and four dyads of patient and family member participated. Subjective QoL in patients and family members differed significantly, as did satisfaction with care delivery. In both groups family support contributed significantly to QoL. In the models 40% of the variance in QoL in patients and relatives could be explained. While the quality of life of the family members was affected by the patients' knowledge about the disease and the reason for their current hospitalization, patient QoL scores had no influence on the QoL of family members. The patients' QoL, however, depended significantly on the QoL of the family members. Interventions should address both PWE and family members and focus on the self-care improvement of PWE and the well-being and coping of family members. A patient-centred approach needs to include both the PWE and

    To support the process of effective family decision making, it is important to recognize and understand informal roles that various family members may play in the end-of-life decision-making process. To describe some informal roles consistently enacted by family members involved in the process of end-of-life decision making in intensive care units. Ethnographic study. Data were collected via participant observation with field notes and semistructured interviews on 4 intensive care units in an academic health center in the mid-Atlantic United States from 2001 to 2004. The units studied were a medical, a surgical, a burn and trauma, and a cardiovascular intensive care unit. Health care clinicians, patients, and family members. Informal roles for family members consistently observed were primary caregiver, primary decision maker, family spokesperson, out-of-towner, patient's wishes expert, protector, vulnerable member, and health care expert. The identified informal roles were part of families' decision-making processes, and each role was part of a potentially complicated family dynamic for end-of-life decision making within the family system and between the family and health care domains. These informal roles reflect the diverse responses to demands for family decision making in what is usually a novel and stressful situation. Identification and description of these informal roles of family members can help clinicians recognize and understand the functions of these roles in families' decision making at the end of life and guide development of strategies to support and facilitate increased effectiveness of family discussions and decision-making processes.

    We report on neuropsychological testing done with a family in which many members reported severe face recognition impairments. These 10 individuals were high functioning in everyday life and performed normally on tests of low-level vision and high-level cognition. In contrast, they showed clear deficits with tests requiring face memory and judgements of facial similarity. They did not show deficits with all aspects of higher level visual processing as all tested performed normally on a challenging facial emotion recognition task and on a global-local letter identification task. On object memory tasks requiring recognition of particular cars and guns, they showed significant deficits so their recognition impairments were not restricted to facial identity. These results strongly suggest the existence of a genetic condition leading to a selective deficit of visual recognition.

    Full Text Available The article intends to be a screening of family benefits in the 28 Member States of the European Union (EU and to contribute to the research of shared trends with respect to family approach in these countries. Four types of family benefits including eight distinctive categories are analysed: child-benefit, child care allowances, child-raising allowances, and other benefits (birth and adoption grants, allowance for single parents, special allowances for children with disabilities, advance payments for maintenance and other allowances. The paper is based on primary and secondary analysis of 28 sets of national data provided through the European Union's Mutual Information System on Social Protection (MISSOC. Three categories of member states are considered: founder member states of the EU, other “old” member states, and the new Central and Eastern ones. Chronological development of national regulations with impact on family benefits is analysed in connection with the moment of becoming a member state. Various forms of family benefits legislation and their main subjects of interest are further researched. The last part of the article looks at the coverage of family benefits. Seven member states operate in this respect based on regulations adopted before EU accession. Belgium, Finland, and Lithuania have the “most preserved” family regulations per category of member states. The first three topics of family regulations are: child, family, and allowance / benefit. The most frequently provided family benefits are: birth and adoption grants, and special allowance for children with disabilities. All eight family benefits are provided in France, Finland, Hungary, and Slovenia. Only two types of family benefits are available in Ireland, Spain, and Cyprus.

    Members of the plant NITRATE TRANSPORTER 1/PEPTIDE TRANSPORTER (NRT1/PTR) family display protein sequence homology with the SLC15/PepT/PTR/POT family of peptide transporters in animals. In comparison to their animal and bacterial counterparts, these plant proteins transport a wide variety of substrates: nitrate, peptides, amino acids, dicarboxylates, glucosinolates, IAA, and ABA. The phylogenetic relationship of the members of the NRT1/PTR family in 31 fully sequenced plant genomes allowed the identification of unambiguous clades, defining eight subfamilies. The phylogenetic tree was used to determine a unified nomenclature of this family named NPF, for NRT1/PTR FAMILY. We propose that the members should be named accordingly: NPFX.Y, where X denotes the subfamily and Y the individual member within the species. Copyright © 2013 Elsevier Ltd. All rights reserved.

    To investigate the impact of family members and health care providers on the use of folic acid supplements in pregnant women, and to provide basic data for improving the effectiveness of folic acid intervention. A cross-sectional study was conducted in hospitals and households from June to September in 2009. Face-to-face anonymous questionnaires were distributed to 2094 women, who were pregnant at least three months or postpartum in one year, in two counties of Gansu Province. The awareness rate of folic acid was in 62.2% of 2094 pregnant women, and 25.4% of them have taken folic acid. Higher knowledge about folic acid of family members (OR = 0.268, 95% CI 0.208 - 0.346), agreed with taking folic acid by family members (OR = 0.103, 95% CI 0.031 -0.338), and urging pregnant women to take folic acid by family members (OR = 0.147, 95% CI 0.115 - 0.190) were significant predictors for having folic acid taken by pregnant women. Propagating knowledge related to folic acid (OR = 0.252, 95% CI 0.197 - 0.323) and directing pregnant women to use folic acid (OR = 0.168, 95% CI 0.096 - 0.296) by health care providers were also the important predictors for folic acid intake. Family members and health care providers play an important role in affecting the use of folic acid among pregnant women. In order to improve the effectiveness of intervention with folic acid, family members of pregnant women and health care providers should be included into the target population to receive an intensive propaganda campaign on folic acid education to improve the use of folic acid in pregnant women extensively.

    Laws in China relating to HIV disclosure are inconsistent. After a patient has tested HIV-positive, service providers struggle to decide who should be informed first: patients, family members, or both. To understand service providers' attitudes and practices regarding the HIV notification process in China, 1101 service providers from a southwestern province of China were surveyed. Opinions were gathered from providers at five different levels of health care facilities (provincial, city, county, township and village). A mixed methods approach was used to analyze perceptions of informing family members of a patient's HIV status. Quantitative analysis was used to examine whether providers held a favorable attitude toward notifying family members first and qualitative analysis was used to explore the reasons and consequences of notifying family members first. Nearly half of service providers felt family members should be informed of a patient's HIV status first. Providers who were older, had contact with HIV patients, or had less medical education were more likely to agree with a family-first notification practice. Psychological pressure, concern about protecting family members, the need for family support, and consideration for local regulations were cited as the main reasons for this practice. There is an immediate need to re-examine HIV notification policies so that there are consistent guidelines and procedures for providers throughout China.

    The present study assessed the impact of suicide and distress on suicidal ideation in a sample of 93 Portuguese family members bereaved by suicide. A control community sample of 102 adults also participated. After controlling for educational level, those bereaved by the suicide of a family member were found to have higher levels of suicidal ideation. Forty-two percent of family members had Suicide Ideation Questionnaire scores at or above the cutoff point. General distress, depression, anxiety, and hostility related to suicidal ideation, whereas time since suicide also interacted with general distress and depression in predicting suicidal ideation.

    When someone has a mental illness, family members may share the experience of stigma. Past research has established that family members' experiences of stigma by association predict psychological distress and lower quality-of-life. The present study, conducted with 503 family members of people with mental illness examined the prevalence of 14 different coping strategies. Of greater importance, we examined the role of these coping strategies as mediators of the relationships between stigma by association and family burden, on the one hand, and outcomes, such as psychological distress and quality-of-life, on the other. The results showed that both perceived stigma by association and family burden are associated with greater psychological distress and lower quality-of-life, and that most coping strategies mediate these relationships. Adaptive coping strategies were related to reduced negative outcomes, while most maladaptive coping strategies were related to enhanced negative outcomes. Implications for intervention development are discussed.

    This study was aimed to test the structured anger management nursing program for the family members of patients with alcohol use disorders (AUDs). Families with the AUDs suffer from the dysfunctional family dynamic caused by the patients' deteriorative disease processes of alcohol dependence. Family members of AUDs feel bitter and angry about the uncontrolled behaviors and relapses of the patients in spite of great effort for a long time. This chronic anger threatens the optimal function of the family as well as obstructs the family to help the patients who are suffering from AUDs. Sixty three subjects were participated who were referred from community mental health centers, alcohol consultation centers, and an alcohol hospital in Korea. Pre-post scores of the Korean Anger Expression Inventory were used to test the program. An anger management program was developed and implemented to promote anger expression and anger management for the family members of the patients with AUDs. The total anger expression score of the experimental group was significantly more reduced as compared with that of the control group. Subjects in the experimental group reported after the program that they felt more comfortable and their life was changed in a better way. The anger management program was effective to promote anger expression and anger management for family members of AUDs. Nurses need to include family members in their nursing process as well as to care of patients with AUDs to maximize nursing outcome and patient satisfaction. 2010 Elsevier Inc. All rights reserved.

    In China, few people are aware of the amount and source of their salt intake. We conducted a survey to investigate the consumption and sources of dietary salt using the "one-week salt estimation method" by weighing cooking salt and major salt-containing food, and estimating salt intake during dining out based on established evidence. Nine hundred and three families (1981 adults and 971 children) with students in eight primary or junior high schools in urban and suburban Beijing were recruited. On average, the daily dietary salt intake of family members in Beijing was 11.0 (standard deviation: 6.2) g for children and adolescents (under 18 years old), 15.2 (9.1) g for adults (18 to 59 years old), and 10.2 (4.8) g for senior citizens (60 years old and over), respectively. Overall, 60.5% of dietary salt was consumed at home, and 39.5% consumed outside the home. Approximately 90% of the salt intake came from cooking (household cooking and cafeteria or restaurant cooking), while less than 10% came from processed food. In conclusion, the dietary salt intake in Beijing families far surpassed the recommended amounts by World Health Organization, with both household cooking and dining-out as main sources of salt consumption. More targeted interventions, especially education about major sources of salt and corresponding methods for salt reduction should be taken to reduce the risks associated with a high salt diet.

    This paper reviews the evidence on the significance of sibling inclusion in family interventions and support during early psychosis. This narrative review presents the current research related to the importance of family work during early psychosis, the needs and developmental significance of siblings during adolescence and early adulthood, the protective effects of sibling relationships, and the characteristics of early psychosis relevant to the sibling experience. It will also review the evidence of the sibling experience in chronic physical illness and disability, as well as long-term psychotic illness. Despite the evidence that working with families is important during early psychosis, siblings have been largely ignored. Siblings are an important reciprocal relationship of long duration. They play an important role in development during adolescence and early adulthood. These relationships may be an underutilized protective factor due to their inherent benefits and social support. Developmental theories imply that early psychosis could negatively impact the sibling relationship and their quality of life, effecting personality development and health outcomes. The evidence shows that adolescent physical illness or disability has a significantly negative impact on the sibling's quality of life and increases the risk for the onset of mental health issues. Long-term psychotic illness also results in negative experiences for siblings. Current evidence shows that siblings in early psychosis experience psychological distress and changes in functional performance. Further research using standard measures is required to understand the impact early psychosis has on the sibling relationship and their quality of life. © 2013 Wiley Publishing Asia Pty Ltd.

  15. Targeting functional motifs of a protein family

    2016-10-01

    The structural organization of a protein family is investigated by devising a method based on the random matrix theory (RMT), which uses the physiochemical properties of the amino acid with multiple sequence alignment. A graphical method to represent protein sequences using physiochemical properties is devised that gives a fast, easy, and informative way of comparing the evolutionary distances between protein sequences. A correlation matrix associated with each property is calculated, where the noise reduction and information filtering is done using RMT involving an ensemble of Wishart matrices. The analysis of the eigenvalue statistics of the correlation matrix for the β -lactamase family shows the universal features as observed in the Gaussian orthogonal ensemble (GOE). The property-based approach captures the short- as well as the long-range correlation (approximately following GOE) between the eigenvalues, whereas the previous approach (treating amino acids as characters) gives the usual short-range correlations, while the long-range correlations are the same as that of an uncorrelated series. The distribution of the eigenvector components for the eigenvalues outside the bulk (RMT bound) deviates significantly from RMT observations and contains important information about the system. The information content of each eigenvector of the correlation matrix is quantified by introducing an entropic estimate, which shows that for the β -lactamase family the smallest eigenvectors (low eigenmodes) are highly localized as well as informative. These small eigenvectors when processed gives clusters involving positions that have well-defined biological and structural importance matching with experiments. The approach is crucial for the recognition of structural motifs as shown in β -lactamase (and other families) and selectively identifies the important positions for targets to deactivate (activate) the enzymatic actions.

  16. Psychiatric Worker and Family Members: Pathways Towards Co-Operation Networks within Psychiatric Assistance Services.

    2014-03-04

    The family's role in patient care was greatly altered by Law 180. This law, introduced in Italy in 1978, led to a gradual phasing out of custodial treatment for psychiatric patients. This different mindset, which views the family as an alternative to institutionalization, leads to it being seen as an essential entity in the setting up of community service dynamics. We interviewed health professionals in order to understand obstacles of collaboration between family members and mental health care workers. The goal was to uncover actions that promote collaboration and help build alliances between families and psychiatric workers. Results showed that health professionals view the family as a therapeutic resource. Despite this view, family members were rarely included in patient treatment. The reasons is: the structures have a theoretical orientation of collaboration with the family but, for nurses not are organized a few meeting spaces with family members. Services should create moments, such as multi-family groups or groups of information, managed by nurses and not only by doctors. These occasions it might facilitate the knowledge between professionals and family members.

    The overall objective of this study was to explore and describe the phenomenon of families who are involved in deciding about withdrawal of life-support treatment of a family member. A phenomenon analysis was undertaken in two phases. During the first phase, secondary analysis of primary data was done on the family used in Burger's study (1996: 1-175) and was followed up by phenomenological interviews with families used as member checking from the same circumstances and according to the same criteria that Burger (1996: 1-185) used in her study. Data were analysed in collaboration with an independent coder. The family used as member checking in this study is also used as data control. A literature control was conducted as part of data control. The themes that were identified included were: physical and bodily experiences of families; defence mechanisms used by families to cope with grief; emotional experiences of families; need of knowledge/perceptions/outlook on life/internal conflict/feelings of guilt/ability to make decisions/respect of patient wishes/the effect of time and prior experiences; support needed by an given to families; spiritual and supernatural experiences/hope/acceptance/ability to 'let go' of the patient. In phase two, guidelines were described for psychiatric nurse specialists to mobilise resources for families to promote, maintain and restore their mental health as an integral part of health.

    The quality of the relationship between patients with many illnesses and their family members has been shown to affect the well-being of both. Yet, relationship quality has not been studied in traumatic brain injury (TBI), and giving and receiving aspects have not been distinguished. The present study of veterans with TBI examined associations between relationship quality and caregiver burden, satisfaction with caregiving, and veterans' competence in interpersonal functioning, rated by veterans and family members. In this cross-sectional study, 83 veterans and their family members were interviewed at home. Measures of quality of relationship, veterans' interpersonal competence and sociodemographics were collected for both, caregiver burden and satisfaction for family members only. As predicted, veteran-rated Qrel/Giving was associated with family-rated Qrel/Receiving, and veteran-rated Qrel/Receiving with family-rated Qrel/Giving. Lower caregiver burden and higher caregiving satisfaction were associated with higher Qrel/Receiving scores but not with Qrel/Giving scores. Veterans' interpersonal competence was associated with total Qrel as rated by either veterans or family members. Relationship quality should be included in family research in TBI, and giving and receiving aspects should be differentiated. Findings suggest that lower caregiver burden and greater satisfaction should be more achievable by increasing caregivers' sense of benefits received from the relationship.

    This article critically examines the family-oriented social policies of the Singapore government aimed at supporting families caring for older members. The sectors focused on are financial security, health, and housing. Singaporeans have been reminded that the family should be the first line of defense for aging families, followed by the community - the state would step in as the last resort. Drawing from recent research and examination of the state policies, the author argues that more should be done to help family caregivers looking after elder relatives. Recommendations for innovative ways to recognize and reward family carers conclude the paper.

    To investigate how family members' attitudes toward functional regain, and patients' knowledge and intention of independence influence poststroke rehabilitation. Cross-sectional study. Three rehabilitation inpatient settings. Younger (n=79) and older (n=84) poststroke patients, along with their family members (spouses, n=104; children, n=59). Not applicable. Custom-designed questionnaires were used to tap into the patients' knowledge about rehabilitation (Patient's Rehabilitation Questionnaire-Knowledge About Rehabilitation) and intention of independence (Patient's Rehabilitation Questionnaire-Intention of Independence), and family members' attitudes toward patients in performing basic activities of daily living (BADL) (Family Member Attitudes Questionnaire-BADL) and instrumental activities of daily living (Family Member Attitudes Questionnaire-instrumental activities of daily living). The rehabilitation outcomes included gains in motor, cognitive, and emotional functions, and self-care independence, measured with common clinical instruments. The Family Member Attitudes Questionnaire-BADL predicted cognitive outcome and the Patient's Rehabilitation Questionnaire-Intention of Independence predicted motor outcome for both groups. Differential age-related effects were revealed for the Patient's Rehabilitation Questionnaire-Intention of Independence in predicting emotional outcome only for the younger group, and self-care independence only for the older group. Patients' intention of independence positively affected motor recovery, while family members' positive attitudes promoted cognitive regain. The findings suggested plausible age-related differences in how patients' intentions affect emotion versus self-care independence outcomes. Future studies should explore strategies for promoting positive attitudes toward independence among patients and family members during poststroke rehabilitation.

    To clarify the verbal communication of feelings between families and patients in Japanese palliative care units from the perspective of bereaved family members by examining (1) proportions of families' and patients' verbalization of six feelings (gratitude, love, seeking forgiveness, giving forgiveness, wishes after death, and continuing bonds), (2) recognition of receiving these feelings through verbalization from the family's perspective, and (3) the specific attitudes of family members that influence their verbalizations. In 2010, a cross-sectional survey was conducted with 968 bereaved families of cancer patients in palliative care units across Japan. Five hundred thirty-seven responses were analyzed. (1) "Gratitude" was verbalized most often (families: 47%; patients: 61%), and "expressing forgiveness" least often (families: 16%; patients: 11%). (2) Even if the words were not used, 81.2% to 88.2% of families answered that they had received the patient's feelings, and 71.8% to 85.4% of families felt the patient had received their feelings. (3) Multiple logistic regression analyses indicated that the strongest attitudes determining verbalizing were "not wanting to say farewell without conveying feelings," "a daily basis of expressing," and "heart-to-heart communication" (ishin-denshin). For both families and patients, verbalizing feelings was difficult. Our results showed that families' and patients' verbalizing and receiving of feelings must be aligned to understand their communication at the end of life in Japan. Future research is needed to verify how attitude helps promote or inhibit verbalization. Copyright © 2017 John Wiley & Sons, Ltd.

    When caring for a family as a unit, it is as crucial to communicate with the family members of a patient as it is with the patient. However, there is a lack of research on the views of nursing students on communicating with the family members of patients, and little has been mentioned in the nursing curriculum on this topic. The aim of this study was to explore nursing students' experiences of communicating with the family members of patients. A qualitative descriptive study. A total of 42 nursing students (21 undergraduate year-two students and 21 were master's year-one students) from one school of nursing in Hong Kong participated in in-depth individual interviews. Content analysis was adopted. The trustworthiness of this study was ensured by enhancing its credibility, confirmability, and dependability. Two main themes were discerned. The first, "inspirations gained from nursing student-family communication", included the following sub-themes: (a) responding to enquiries clearly, (b) avoiding sensitive topics, (c) listening to the patient's family, and (d) sharing one's own experiences. The second, "emotions aroused from nursing student-family communication", had the following sub-themes: (a) happiness, (b) anger, (c) sadness, and (d) anxiety. More studies on the perspectives of nursing students on communicating with family members should be conducted, to strengthen the contents and learning outcomes of nursing student-family communication in the existing nursing curriculum.

    2013-01-01

    Full Text Available The aim of this study was to explore family members’ experiences of everyday life in families with adult people living with type 1 diabetes. The grounded theory method was used to gather and analyse data from the interviews of nineteen family members. Six concepts describing the family members’ views on everyday living with diabetes were generated on the basis of the data. Everyday life with diabetes is described as being intertwined with hypoglycemia. Becoming acquainted with diabetes takes place little by little. Being involved in the management and watching self-management from the sidelines are concepts describing family members’ participation in the daily management of diabetes. The family members are also integrating diabetes into everyday life. Living on an emotional roller-coaster tells about the thoughts and feelings that family members experience. Family members of adult people with diabetes are involved in the management of the diabetes in many ways and experience many concerns. The family members’ point of view is important to take into consideration when developing education for adults with diabetes.

    Full Text Available Abstract Background Nursing home residents are frequently sent to hospital for diagnostic tests or to receive acute health care services. These transfers are both costly and for some, associated with increased risks. Although improved technology allows long-term care facilities to deliver more complex health care on site, if this is to become a trend then residents and family members must see the value of such care. This qualitative study examined resident and family member perspectives on in situ care for pneumonia. Methods A qualitative descriptive study design was used. Participants were residents and family members of residents treated for pneumonia drawn from a larger randomized controlled trial of a clinical pathway to manage nursing home-acquired pneumonia on-site. A total of 14 in-depth interviews were conducted. Interview data were analyzed using the editing style, described by Miller and Crabtree, to identify key themes. Results Both residents and family members preferred that pneumonia be treated in the nursing home, where possible. They both felt that caring and attention are key aspects of care which are more easily accessible in the nursing home setting. However, residents felt that staff or doctors should make the decision whether to hospitalize them, whereas family members wanted to be consulted or involved in the decision-making process. Conclusion These findings suggest that interventions to reduce hospitalization of nursing home residents with pneumonia are consistent with resident and family member preferences.

  13. Strange Stars : An interesting member of the compact object family

    2008-01-01

    We have studied strange star properties both at zero temperature and at finite temperatures and searched signatures of strange stars in gamma-ray, x-ray and radio astronomy. We have a set of Equations of State (EoS) for strange quark matter (SQM) and solving the TOV equations, we get the structure of strange stars. The maximum mass for a strange star decreases with the increase of temperature, because at high temperatures, the EoS become softer. One important aspect of strange star is that, surface tension depends on the size and structure of the star and is significantly larger than the conventional values. Moment of inertia is another important parameter for compact stars as by comparing theoretical values with observed estimate, it is possible to constrain the dense matter Equation of State. We hope that this approach will help us to decide whether the members of the double pulsar system PSR J0737-3039 are neutron stars or strange stars.

  14. CHIS - Information concerning the health insurance of frontalier workers who are family members of a CHIS main member

    CERN Multimedia

    2014-01-01

    We recently informed you that the Organization was still in discussions with the Host State authorities to clarify the situation regarding the health insurance of frontalier workers who are family members (as defined in the Staff Rules and Regulations) of a CHIS main member, and that we were hoping to arrive at a solution soon.   After extensive exchanges, we finally obtained a response a few days ago from the Swiss authorities, with which we are fully satisfied and which we can summarise as follows: 1) Frontalier workers who are currently using the CHIS as their basic health insurance can continue to do so. 2) Family members who become frontalier workers, or those who have not yet exercised their “right to choose” (droit d’option) can opt to use the CHIS as their basic health insurance. To this end, they must complete the form regarding the health insurance of frontaliers, ticking the LAMal box and submitting their certificate of CHIS membership (available from U...

    Full Text Available Background: HIV testing for family members of HIV-positive patients may enhance disclosure of status of spouses, encourage family social support and improve access to HIV services. Objective was to employ the approach of routine HIV testing to determine the prevalence of HIV among family members of both HIV positive and negative patients on admission in a federal HIV treatment designated hospital in Western Nigeria Methodology: This prospective study was conducted between January 2006 and June 2009. Ethical clearance was obtained from the Research and Ethics committee of the hospital prior to the study. Informed consent was obtained from each participant. HIV testing was offered to consenting family members of HIV positive and negative patients on admission. The family members included spouses, children of patients, parents of paediatric patients and other family members. Analysis was done in frequencies and percentages Results: 162 family members of 184 patients were tested. Spouses were, 81 (50.0%; fathers, 14 (8.6%; mothers, 20 (12.3%; children, 19 (11.7% and others family members, 28 (17.3%. 151 (93.2% of testers were first timers. Majority of those tested (82.1% had post-test counseling. The overall HIV prevalence was 12.3% (20/162. HIV prevalence within different family members was 14.8% (12/81, 20% (4/20, 7.1% (1/14, 10.5% (2/19 and 3.6% (1/28 for spouses, mothers, fathers, children and others respectively.In addition, the prevalence of HIV among family members of HIV positive and negative patients was 15.6% (14/90 and 8.3% (6/72 respectively. Of 12 spouses that were positive, 7 (13.5% were HIV-discordant; and in 71.4% (5/7 of discordant couples, the spouse was positive while the patient on admission was negative. Conclusion: The results indicate that routine HIV testing of family members of patients on admission is a strategy for identification of vast number of HIV infected persons. This method is not only innovative, but also a novel

    We obtained moderate S/N ($\\sim85$) spectra at a realized resolution of R $\\sim100$ for 11 members of the Iannini family, until recently the youngest known family at under 5 million years of age \\citep{bib.nes03}. The spectra were acquired using the Echellette Spectrograph and Imager in its low-resolution prism mode on the Keck II telescope. The family members belong to the S-complex of asteroids with perhaps some K class members. The Iannini family members's average spectral slope, defined as the slope of the best-fit line constrained to pivot about 1 at 550 nm, is $(0.30\\pm0.04)/\\mu m$, matching the $(0.26\\pm0.03)/\\mu m$ reported by \\citet{bib.jed04} using SDSS \\citep{bib.ive02} color photometry. Using our spectra for this family as well as new observations of Karin family members \\citep{bib.ver06} and new classifications of some older families we revised the space weathering rate of S-complex asteroids originally determined by \\citet{bib.jed04}. Following \\citet{bib.jed04} we parameterize the space weather...

    To explore the coping strategies used by affected family members of a relative with substance misuse. Families play an important role in supporting a relative with substance misuse. However, the experience often has an adverse effect on their general well-being, the extent of which depends largely on their coping strategies. An interpretative phenomenological analysis study. Data were collected between January - December 2015. Semistructured, audio-recorded qualitative interviews were conducted with 31 affected family members. Three main themes and related subthemes were abstracted from the data illustrating how participants coped with their relative's substance misuse: (1) Seeking timely access to evidence-based information; (2) Enhancing personal coping strategies and (3) Accessing informal and formal support. Greater investment is needed in support services for affected family members, particularly in regional and rural areas. A wide range of accessible evidence-based information and informal and formal support, including telephone and online support, is needed to assist them to cope in this crucial support-giving role. Affected family members need to adopt a flexible set of coping strategies while supporting a relative with substance misuse. Family and friends, alcohol and other drug services, mental health nurses and other clinicians have a critical role providing emotional, instrumental and educational support to affected family members to enhance their adaptive coping strategies. © 2017 John Wiley & Sons Ltd.

    To explore the experiences of family members of patients treated with extracorporeal membrane oxygenation. Sudden onset of an unexpected and severe illness is associated with an increased stress experience of family members. Only one study to date has explored the experience of family members of patients who are at high risk of dying and treated with extracorporeal membrane oxygenation. A qualitative descriptive research design was used. A total of 10 family members of patients treated with extracorporeal membrane oxygenation were recruited through a convenient sampling approach. Data were collected using open-ended semi-structured interviews. A six-step process was applied to analyse the data thematically. Four criteria were employed to evaluate methodological rigour. Family members of extracorporeal membrane oxygenation patients experienced psychological distress and strain during and after admission. Five main themes (Going Downhill, Intensive Care Unit Stress and Stressors, Carousel of Roles, Today and Advice) were identified. These themes were explored from the four roles of the Carousel of Roles theme (decision-maker, carer, manager and recorder) that participants experienced. Nurses and other staff involved in the care of extracorporeal membrane oxygenation patients must pay attention to individual needs of the family and activate all available support systems to help them cope with stress and strain. An information and recommendation guide for families and staff caring for extracorporeal membrane oxygenation patients was developed and needs to be applied cautiously to the individual clinical setting. © 2016 John Wiley & Sons Ltd.

    Previous studies have shown that inpatients and families in academic settings have a limited ability to recall either their medical team members or the roles of those members. This is an important issue for patient and family satisfaction as well as patient safety. The objective of this study was to increase families' recognition of medical team members' roles. We established a multidisciplinary quality improvement leadership team, measured family recognition of medical team members and their roles, and conducted 2 PDSA (Plan-Do-Study-Act) cycles. The first intervention was standardization of the content and delivery of our verbal team introductions to ensure inclusion of essential elements and family engagement. The second intervention was addition of an informational white board in each patient room. The prospective study included 105 families in the preintervention phase, 103 post-PDSA cycle 1, and 92 post-PDSA cycle 2. After conduction of 2 PDSA cycles, the recognition of the attending role increased from 49% to 87% (P = .000), the resident role from 39% to 73% (P = .000), and the medical student from 75% to 89% (P = .038). The multidisciplinary quality improvement model was effective in improving family recognition of the roles of attending physicians, resident physicians, and medical students. Consistent attention to engaging the families and explaining our roles as well as providing informational white boards are effective interventions to facilitate this process.

    2014-01-01

    Members of the well-conserved mannose receptor (MR) protein family have been functionally implicated in diverse biological and pathological processes. Importantly, a proposed common function is the internalization of collagen for intracellular degradation occurring during bone development, cancer...... invasion, and fibrosis protection. This functional relationship is suggested by a common endocytic capability and a candidate collagen-binding domain. Here we conducted a comparative investigation of each member's ability to facilitate intracellular collagen degradation. As expected, the family members u......PARAP/Endo180 and MR bound collagens in a purified system and internalized collagens for degradation in cellular settings. In contrast, the remaining family members, PLA2R and DEC-205, showed no collagen binding activity and were unable to mediate collagen internalization. To pinpoint the structural elements...

    Members of the Ikaros family of zinc-finger transcription factors have been shown to be critical for immune and blood cell development. However, the role of the most divergent family member, Pegasus, has remained elusive, although it shows conservation to invertebrate Hunchback proteins that influence embryonic patterning through regulation of homeodomain genes. Zebrafish was employed as a relevant model to investigate the function of Pegasus since it possesses a single pegasus orthologue with high homology to its mammalian counterparts. During zebrafish embryogenesis pegasus transcripts were initially maternally-derived and later replaced by zygotic expression in the diencephalon, tectum, hindbrain, thymus, eye, and ultimately the exocrine pancreas and intestine. Morpholino-mediated knockdown of the zebrafish pegasus gene resulted in disrupted left-right asymmetry of the gut and pancreas. Molecular analysis indicated that zebrafish Pegasus localised to the nucleus in discrete non-nucleolar structures and bound the 'atypical' DNA sequence GN3GN2G, confirming its presumed role as a transcriptional regulator. In vivo transcriptome analysis identified candidate target genes, several of which encoded homeodomain transcription factors. One of these, pitx2, implicated in left-right asymmetry, possessed appropriate 'atypical' Pegasus binding sites in its promoter. Knockdown of Pegasus affected both the level and asymmetry of pitx2 expression, as well as disrupting the asymmetry of the lefty2 and spaw genes, explaining the perturbed left-right patterning in pegasus morphants. Collectively these results provide the first definitive insights into the in vivo role of Pegasus, supporting the notion that it acts as a broader regulator of development, with potential parallels to the related invertebrate Hunchback proteins.

    Family members of people with serious mental illness (SMI) at times report that they act to stop their ill relative from self harm or harming others. This study examines the relationship between the perception of risk of harm and family distress, burden, empowerment, coping, physical and mental health, appraisal of the caregiving experience, family communication, and family functioning. The study is a secondary analysis of baseline data collected for a randomized study of the family-to-family peer driven education program (FTF). Four hundred thirty-four enrolled individuals who were seeking to participate in FTF completed survey items that asked if they had tried to stop or prevent their ill family member from harming themselves or others in the last 30 days. Participants who perceived a recent risk of harm by their ill relative reported more negative appraisals of caregiving, greater psychological distress, poorer mental health and greater objective burden compared with those who did not perceive a recent risk of harm. The results suggest that families of persons with SMI should be asked about perceived risk of harm to self and others, and the presence of perceived risk of harm should serve as a red flag indicating the need for further evaluation of the family experience and additional support for the family.

    Full Text Available In 2003, Acanthamoeba polyphaga mimivirus (APMV was discovered as parasitizing Acanthamoeba. It was revealed to exhibit remarkable features, especially odd genomic characteristics, and founded viral family Mimiviridae. Subsequently, a second family of giant amoebal viruses was described, Marseilleviridae, whose prototype member is Marseillevirus, discovered in 2009. Currently, the genomes of seven different members of this family have been fully sequenced. Previous phylogenetic analysis suggested the existence of three Marseilleviridae lineages: A, B and C. Here, we describe a new member of this family, Brazilian Marseillevirus (BrMV, which was isolated from a Brazilian sample and whose genome was fully sequenced and analyzed. Surprisingly, data from phylogenetic analyses and comparative genomics, including mean amino acid identity between BrMV and other Marseilleviridae members and the analyses of the core genome and pan-genome of marseilleviruses, indicated that this virus can be assigned to a new Marseilleviridae lineage. Even if the BrMV genome is one of the smallest among Marseilleviridae members, it harbors the second largest gene content into this family. In addition, the BrMV genome encodes 29 ORFans. Here, we describe the isolation and genome analyses of the BrMV strain, and propose its classification as the prototype virus of a new lineage D within the family Marseilleviridae.

    To investigate the relationships between public stigma, stigma by association (SBA), psychological distress, perceived closeness, perceived heredity, and the type of family relationship among family members of people with a mental illness. In this cross-sectional survey, data from 527 family members of people with a mental illness were analyzed. Perceptions of public stigma were found to be positively related to SBA and SBA correlated with greater psychological distress and less perceived closeness. SBA also mediated relationships between perceived public stigma and psychological distress, and between perceived public stigma and perceived closeness. Further, among participants who reported SBA, immediate family members showed lower levels of perceived closeness than extended family members. Also, the perceived heredity of mental illness was associated with perceptions of public stigma and psychological distress. The findings suggest that family members of people with a mental illness could benefit from education on mental illnesses, their treatment, and the extent to which they are hereditary. Additionally, particular attention should be paid to the psychological needs that arise from being a caregiver of someone with a mental illness.

    2015-04-01

    Most dementia research investigates the social context of declining ability through studies of decision-making around medical treatment and end-of-life care. This study seeks to fill an important gap in research about how family members manage the risks of functional decline at home. Drawing on three waves of in-depth interviewing in 2012-2014, it investigates how family members in US households manage decline in an affected individual's natural range of daily activities over time. The findings show that early on in the study period affected individuals were perceived to have awareness of their decline and routinely drew on family members for support. Support transformed when family members detected that the individual's deficit awareness had diminished, creating a corresponding increase in risk of self-harm around everyday activities. With a loss of confidence in the individual's ability to regulate his or her own activities to avoid these risks, family members employed unilateral practices to manage the individual's autonomy around his or her activity involvements. These practices typically involved various deceits and ruses to discourage elders from engaging in activities perceived as potentially dangerous. The study concludes by discussing the implications that the social context of interpretive work around awareness and risk plays an important role in how families perceive an elder's functional ability and manage his or her activity involvements.

    This study examines the impact of Family Healthware™ on communication behaviors; specifically, communication with family members and health care providers about family health history. A total of 3786 participants were enrolled in the Family Healthware™ Impact Trial (FHITr) in the United States from 2005-7. The trial employed a two-arm cluster-randomized design, with primary care practices serving as the unit of randomization. Using generalized estimating equations (GEE), analyses focused on communication behaviors at 6month follow-up, adjusting for age, site and practice clustering. A significant interaction was observed between study arm and baseline communication status for the family communication outcomes (p'sfamily members about family history risk (OR=1.24, p=0.042) and actively collecting family history information at follow-up (OR=2.67, p=0.026). Family Healthware™ did not have a significant effect on family communication among those already communicating at baseline, or on provider communication, regardless of baseline communication status. Greater communication was observed among those at increased familial risk for a greater number of diseases. Family Healthware™ prompted more communication about family history with family members, among those who were not previously communicating. Efforts are needed to identify approaches to encourage greater sharing of family history information, particularly with health care providers. Copyright © 2015 Elsevier Inc. All rights reserved.

    Homeobox genes represent a class of transcription factors that play key roles in the regulation of embryogenesis and development. Here we report the identification of a homeobox-containing gene family that is highly conserved at both the nucleotide and amino acid levels in a diverse number of species. These species encompass both vertebrate and invertebrate phylogenies, ranging from Homo sapiens to Drosophila melanogaster. In humans, at least two homeobox sequences from this family were identified representing a previously reported member of this family as well as a novel homeobox sequence that we physically mapped to the 10q25.2-q26.3 region of human Chromosome (Chr) 10. Multiple members of this family were also detected in three additional vertebrate species including Equus caballus (horse), Gallus gallus (Chicken), and Mus musculus (mouse), whereas only single members were detected in Tripneustes gratilla (sea urchin), Petromyzon marinus (lamprey), Salmo salar (salmon), Ovis aries (sheep), and D. melanogaster (fruit fly).

    Full Text Available ABSTRACT OBJECTIVE Understand the quotidian relationships of accompanying family members in an environment of care, which are close to the metaphor of a tribe in hospital environment. METHODQualitative study with data gathered from semi-structured interviews and observations with 16 family members accompanying hospitalized individuals with dependence on self-care. Data were submitted to thematic analysis, and analyzed through the metaphor of "tribe" proposed by comprehensive sociology. RESULTS Family members build up social clusters around caring, where we find traits typical of tribes: emotional ambience; solidarity based on links of sympathy and mutual assistance; an affectual nebula in the process of interaction; a logic of fusion in tactile relations; and communion/religiosity in the process of connecting in a collective identity. CONCLUSION In the presence of tragedy, families build social clusters similar to tribes having care as a totem.

  14. Family members' perceived meaning of visiting nursing home residents in Taiwan.

    The purpose of this article is to report the findings of a study to explore perceived family meaning of visiting older nursing home residents in Taiwan. Family involvement in the care of institutionalized elders benefits residents, family and staff. Families have traditionally been involved through in-person visits. One factor influencing family visits is motivation, which is a vague concept, creating a need to better understand the meaning families ascribe to visiting nursing home residents. Understanding this meaning is necessary to develop intervention programmes that facilitate the quality of families' nursing-home visits. However, little is known about the meaning of family visits to nursing home residents in Asian countries. Data were collected April 2009-2010 in audiotaped, individual, in-depth interviews with 15 family members of residents at four nursing homes in Taiwan. These family members included five women and 10 men, predominantly residents' children and spouses. The meaning of family visits to nursing home residents was captured by five major themes: hoping for recovery, honouring filial/karmic responsibility, insuring care quality, maintaining family relationships and making up for guilt. The findings of this study can be considered by nurses and policy makers when designing interventions and allocating resources to improve the quality of family visits with nursing home residents. These interventions can be tailored to family members' perceived meanings for visiting, e.g. those hoping for residents' recovery may benefit from health-promotion programmes, and those honouring filial/karmic responsibility might be helped by education on different ways to show filial respect. © 2011 Blackwell Publishing Ltd.

    Hispanics show poorer self-management of type 2 diabetes than non-Hispanic whites. Although previous studies have reported socioeconomic and cultural barriers to diabetes self-management by Hispanics, little is known about perceived barriers to diabetes self-management from the perspectives of both Hispanics and their family members. The purpose of the study was to explore perceived barriers among Hispanic immigrants with diabetes and their family members. A qualitative study using 5 focus groups was conducted. A total of 73 Hispanic immigrants with type 2 diabetes (n = 36) and family members (n = 37) were recruited in the southeastern United States for a family-based intervention study of diabetes-self management. Participants were asked to describe their perceptions of barriers to self-management. The 5 sessions were audiotaped and transcribed, translated from Spanish into English, and analyzed using standard content analysis. Demographics, hemoglobin A1C levels, blood pressure, and body mass index (BMI) were obtained both for participants with diabetes and for their family members. Barriers to diabetes self-management identified by participants with diabetes were in 3 major themes categorized as: suffering from diabetes, difficulties in managing the disease, and lack of resources/support. Two key themes emerged pertaining to family members: we can provide support and we lack knowledge. Perceived barriers to diabetes self-management described by Hispanic immigrants with diabetes and family members indicate a lack of intervention strategies to meet their needs. Interventions should include culturally relevant resources, family support, and diabetes self-management skills education.

    To explore patients' and family members' perspectives on how safety threats are detected and managed across care transitions and strategies that improve care transitions from acute care hospitals to complex continuing care and rehabilitation health care organizations. Poorly executed care transitions can result in additional health care spending due to adverse outcomes and delays as patients wait to transfer from acute care to facilities providing different levels of care. Patients and their families play an integral role in ensuring they receive safe care, as they are the one constant in care transitions processes. However, patients' and family members' perspectives on how safety threats are detected and managed across care transitions from health care facility to health care facility remain poorly understood. This qualitative study used semistructured interviews with patients (15) and family members (seven) who were transferred from an acute care hospital to a complex continuing care/rehabilitation care facility. Data were analyzed using a directed content analytical approach. OUR RESULTS REVEALED THREE KEY OVERARCHING THEMES IN THE PERCEPTIONS: lacking information, getting "funneled through" too soon, and difficulty adjusting to the shift from total care to almost self-care. Several patients and families described their expectations and experiences associated with their interfacility care transitions as being uninformed about their transfer or that transfer happened too early. In addition, study participants identified the need for having a coordinated approach to care transitions that engages patients and family members. Study findings provide patients' and family members' perspectives on key safety threats and how to improve care transitions. Of particular importance is the need for patients and family members to play a more active role in their care transition planning and self-care management.

    The purpose of this study was to determine what the individual organ/tissue donor family members appraised as most stressful during the anticipation, confrontation and post-confrontation stages of the organ-donation process. The Lazarus and Folkman stress and coping theory guided the development and interpretation of the study. Family members who had lost a loved one suddenly and consented to donation in 1988 were interviewed. Data were analysed by means of content analysis. Findings showed that family members appraised different types of stressful situations during the three stages. The most frequently reported stressful situations centred around the threat of losing a loved one, confirmation of brain death, failure of the health professionals to identify the loved one as a potential donor and to approach the family regarding organ donation, and adjusting to the many changes associated with the loss. Significantly, five families requested donation, while two readily consented when approached. All family members reported that organ donation had helped with their grief. The findings of this study contribute to the development of knowledge required to guide nursing interventions to provide sensitive care to donors and their families.

    The alternative oxidase (AOX) gene family is a hot candidate for functional marker development that could help plant breeding on yield stability through more robust plants based on multi-stress tolerance. However, there is missing knowledge on the interplay between gene family members that might interfere with the efficiency of marker development. It is common view that AOX1 and AOX2 have different physiological roles. Nevertheless, both family member groups act in terms of molecular-biochemical function as "typical" alternative oxidases and co-regulation of AOX1 and AOX2 had been reported. Although conserved sequence differences had been identified, the basis for differential effects on physiology regulation is not sufficiently explored.This protocol gives instructions for a bioinformatics approach that supports discovering potential interaction of AOX family members in regulating growth and development. It further provides a strategy to elucidate the relevance of gene sequence diversity and copy number variation for final functionality in target tissues and finally the whole plant. Thus, overall this protocol provides the means for efficiently identifying plant AOX variants as functional marker candidates related to growth and development.

    Full Text Available ABSTRACT Objective: to identify the coping strategies of family members of patients with mental disorders and relate them to family member sociodemographic variables and to the patient's clinical variables. Method: this was a descriptive study conducted at a psychiatric hospital in the interior of the state of São Paulo, with 40 family members of hospitalized patients over the age of 18, and who followed the patient before and during hospitalization. We used tools to characterize the subjects and the Folkman and Lazarus Inventory of Coping Strategies. Results: the coping strategies most often used by family members were social support and problem solving. Mothers and fathers used more functional strategies (self-control p=0.037, positive reappraisal p=0.037, and social support p=0,021. We found no significant differences between the strategies and other variables examined. Conclusion: despite the suffering resulting from the illness of a dear one, family members make more use of functional strategies, allowing them to cope with adversities in a more well-adjusted way.

    We examined the factors associated with the disparity in aggressive care preferences between patients with terminal cancer and their family members. Two hundred forty-four consecutive pairs recruited from three university hospitals participated in this study. Each pair completed questionnaires that measured two major aggressive care preferences-admission to the intensive care unit (ICU) and the use of cardiopulmonary resuscitation (CPR). Sixty-eight percent of patients and their family members were in agreement regarding admission to the ICU and 71% agreed regarding CPR. Regarding admission to the ICU, younger, unmarried patients and patients who preferred to die in an institution were more likely to have a different preference from their family caregivers. Regarding CPR, younger patients and patients from severely dysfunctional families were more likely to have a different preference from their family caregivers. Elucidation of the factors associated with such disparities should help reduce them.

    To distinguish the impact of mental illness stigma from that of other negative caregiving experiences, this study examined the unique relationships between stigma and caregiver/family functioning. Adult relatives (n = 437) of individuals with mental illness completed questionnaires regarding caregiving experiences, distress, empowerment, and family functioning, as part of a larger study. Regression analyses examined the relationship between stigma and caregiver/family variables, while controlling for other negative caregiving experiences. Stigma was uniquely associated with caregiver distress, empowerment, and family functioning. Mental illness stigma is a potent source of distress for families and an important target of family services.

    Treatment for multiple myeloma (MM) has significantly advanced in the last decade with the introduction of proteasome inhibitors and immunomodulatory therapies. Unfortunately, MM continues to cause significant morbidity and most patients eventually succumb to the disease. As in other areas of cancer, immunotherapy in MM has also evolved and holds promise to deliver long-lasting remissions or even cure. The signaling lymphocyte activation molecules (SLAM) family of surface proteins represents a group of potential targets for immunotherapy in MM as some of the family members are expressed consistently on plasma cells and also on myeloma propagating pre-plasma cells. Here, we review the SLAM family members in detail, describe their tissue distribution, biologic pathways, as well as relevant pre-clinical studies and clinical trials in MM. Our review demonstrates the value of SLAM family receptors as potential targets for anti-myeloma immunotherapies and outlines how immunotherapeutic approaches can be developed.

    The nuclear family is often the point of departure in much of the existing acculturation research on refugee youth and children of refugees. The influence of other extended family members appears to receive less attention in understanding acculturation processes and intergenerational perspectives. This qualitative study explores the influence of extended family members upon a small sample of Vietnamese refugee parents and their adolescents while they undergo acculturation through their long-term resettlement process in Norway. With repeated interviews over a time span of 3 years, we identified situations and processes in family life in which extended kin become particularly activated and influential. Vietnamese refugee families in Norway keep close contact with extended kin even in the face of geographical distance to kin remaining in Vietnam, or globally dispersed. Aunts, uncles, and cousins are experienced as significant persons in the lives of many adolescents. Additionally, birth order of parents can often influence relationship dynamics among siblings and siblings children. Extended kin surfaced as especially important and influential at critical stages and crisis situations in family life. Extended family, and in particular, parental siblings play important roles in the acculturation experience and family functioning of Vietnamese refugee families in Norway. This has important implications for the study of Vietnamese and other refugee and immigrant families in acculturation research. PMID:24510190

    Full Text Available A qualitative descriptive study aimed at understanding the perceptions of the family members of children regarding well-child check-ups in the context of attention to child healthcare. Data collection was done using semi-structured interviews of 19 families, in the city of Maringá, in the state of Paraná, Brazil, from December 2012 to February 2013. The data was analyzed using content analysis, a thematic modality, which resulted in the thematic category "Revealing well-child check-ups from the family's point of view" and two secondary categories. The results showed the interviewees' insipient knowledge of well-child check-ups, reflecting the lack of adequate guidance about this type of care. The family members showed a preference for care of children by a pediatrician. Although secondary, the family noted the participation of the nurse in this activity. It is considered extremely important that well-child check-ups are valued by family members in order to promote effective multi-professional participation in this modality of attention.

    Full Text Available Background: Schizophrenia is a severe form of mental disorder which is chronic and disabling in nature. Family members of schizophrenia patients often show negative attitude with higher range of expressed emotion (EE towards their relative as they experience significant stress in coping with caring such patients. Material and methods: The present study was conducted to assess EE of family members of patients with schizophrenia. The study setting was outpatient department and psychiatric ward of Assam Medical College Hospital, Dibrugarh. Hundred schizophrenia patients and 100 family members were included in the study through purposive sampling technique. Tools used in the study were socio-demographic and clinical datasheet of patient, socio-demographic datasheet of family member, and Family Attitude Scale. Results: Majority of family members (79% had low level of EE. Their EE had significant association with age of onset of illness. EE was higher when schizophrenia started before 20 years of patient’s age. Age and marital status of the family members had significant associations with their EE. It increased along with increased age of the family members whereas majority of the younger family members had low level of EE. Married family members had higher level of EE. Conclusion: There is need for psychosocial nursing intervention for the family members of schizophrenia patients to help them cope with their stress.

    Living with a parent who is approaching the end of life is profoundly troubling for young people. Research indicates that family communication about life-limiting parental illness can influence how young people manage living with dying. In particular, open communication between family members has been shown to be helpful. This paper reports on a study of young people's experiences of family interaction when a parent is dying and considers the practice of open communication in the context of young people's involvement in giving and receiving family care. A narrative approach was employed based on in-depth semistructured interviews with 10 young people (aged 13-21) living with a parent thought to be in the last year of life. Young people's attitudes toward open communication between family members were more ambivalent and ambiguous than previous research suggests. Parental attempts at open communication were sometimes overlooked by young people, indicating that there may be differences between knowledge given and young people's acknowledgment of sensitive information. Some young people valued open communication as a signifier of the close relationships between family members, while others wanted to exercise more control over what they knew, when, and how. Young people's accounts challenged the positioning of young people as passive recipients of information. Young people were active in shaping family communication in their everyday lives, and deliberative acts of speaking or remaining silent were one way in which young people exercised care for themselves and others. This study extends research on communication within families when a parent has a life-limiting illness and suggests that supporting young people's agency in determining how they receive information may be more beneficial than promoting open communication between family members.

    Over several decades, many cohort studies from the medical epidemiology literature have observed that compared with abstainers, moderate drinkers experience lower risk for a range of diseases. It was very difficult to separate the hypothesised physiological protective effect of moderate drinking from its well-correlated confounders in observational study settings. To investigate the association between current alcohol consumption levels of randomly selected family members and the current self-reported health status of other members living within the same family, using a large-scale representative general population survey. Poisson regression models of the association between randomly selected key respondent alcohol consumption and health status of cohabiting family members using data from the 2008, 2009 and 2010 National Health Interview Surveys. Self-reported alcohol consumption of randomly selected key participants and self-reported health status of adult and child (parent reported) family members living in the same household were measured and compared. After controlling for a large range of commonly reported confounders, inverse associations were evident between light and moderate alcohol consumption of key participants and the prevalence of adverse health status among their family members, including children. The superior health status attributed to family members of light and moderate drinkers is highly likely to be spurious and due to residual confounding rather than physiologically protective effects of alcohol. Unaccounted for confounding is likely to underpin apparent 'protective effects' due to moderate drinking commonly reported from observational studies of all-cause mortality, heart disease, stroke and other chronic diseases. © 2012 The Authors; Internal Medicine Journal © 2012 Royal Australasian College of Physicians.

    Taking care of a family member with a mental illness imposes a burden on various aspects of family life. This burden may be enhanced if the mentally ill individual has a criminal history. This paper aims to summarize the scientific literature dealing with the experiences, needs and burdens of families of mentally ill offenders. We aim to explore the roles that family members play in the rehabilitation of their relative and review the families' needs and burdens. Finally, we aim to investigate whether or not the family strengths are considered in the literature. A literature search in line with the PRISMA statement for systematic reviews and with the recommendations for an integrative review was performed in the ISI Web of Science, PubMed, Elsevier Science Direct and ProQuest databases. Limited research has been carried out into the experiences, needs and burdens of families of mentally ill offenders, with only eight studies fulfilling the inclusion criteria. Families of mentally ill offenders experience more stress than those of mentally ill individuals with no judicial involvement. This is because of the fact that these family members have to deal with both mental health services and judicial systems. The eight retrieved studies focus on needs and burdens, with little reference to strengths or capabilities. The review has highlighted the need for further research into the needs and burdens of families with mentally ill offenders, with a focus on strengths rather than an exclusively problem-oriented perspective. It is important that families become more involved in the health and social care of their relatives to avoid being considered 'second patients'.

    Obesity is characterized by a chronic, low-grade inflammation that contributes to the development of insulin resistance and type 2 diabetes. Cytokines and chemokines produced by immunocompetent cells influence local as well as systemic inflammation and are therefore critical contributors to the pathogenesis of type 2 diabetes. Hence, cytokines that modulate inflammatory responses are emerging as potential targets for intervention and treatment of the metabolic consequences of obesity. The interleukin-1 (IL-1) family of cytokines and receptors are key mediators of innate inflammatory responses and exhibit both pro- and anti-inflammatory functions. During the last decades, mechanistic insights into how the IL-1 family affects the initiation and progression of obesity-induced insulin resistance have increased significantly. Here, we review the current knowledge and understanding, with emphasis on the therapeutic potential of individual members of the IL-1 family of cytokines for improving insulin sensitivity in patients with diabetes.

  13. Opposing functions of classic and novel IL-1 family members in gut health and disease

    Full Text Available In addition to their well-established role(s in the pathogenesis of gastrointestinal (GI-related inflammatory disorders, including inflammatory bowel disease (IBD and inflammation-associated colorectal cancer (CRC, emerging evidence confirms the critical involvement of the interleukin-1 (IL-1 cytokine family and their ligands in the maintenance of normal gut homeostasis. In fact, the paradigm that IBD occurs in two distinct phases is substantiated by the observation that classic IL-1 family members, such as IL-1, the IL-1 receptor antagonist (IL-1Ra, and IL-18, possess dichotomous functions depending on the phase of disease, as well as on their role in initiating vs. sustaining chronic gut inflammation. Another recently characterized IL-1 family member, IL-33, also possesses dual functions in the gut. IL-33 is upregulated in IBD and potently induces Th2 immune responses, while also amplifying Th1-mediated inflammation. Neutralization studies in acute colitis models, however, have yielded controversial results and recent reports suggest a protective role of IL-33 in epithelial regeneration and mucosal wound healing. Finally, although little is currently known regarding the potential contribution of IL-36 family members in GI inflammation/homeostasis, another IL-1 family member, IL-37, is emerging as a potent anti-inflammatory cytokine with the ability to downregulate colitis. This new body of information has important translational implications for both the prevention and treatment of patients suffering from IBD and inflammation-associated CRC.

    The LSF/Grainyhead transcription factor family is involved in many important biological processes, including cell cycle, cell growth and development. In order to investigate the evolutionary conservation of these biological roles, we have characterized two new family members in Caenorhabditis elegans and Xenopus laevis. The C.elegans member, Ce-GRH-1, groups with the Grainyhead subfamily, while the X.laevis member, Xl-LSF, groups with the LSF subfamily. Ce-GRH-1 binds DNA in a sequence-specific manner identical to that of Drosophila melanogaster Grainyhead. In addition, Ce-GRH-1 binds to sequences upstream of the C.elegans gene encoding aromatic L-amino-acid decarboxylase and genes involved in post-embryonic development, mab-5 and dbl-1. All three C.elegans genes are homologs of D.melanogaster Grainyhead-regulated genes. RNA-mediated interference of Ce-grh-1 results in embryonic lethality in worms, accompanied by soft, defective cuticles. These phenotypes are strikingly similar to those observed previously in D.melanogaster grainyhead mutants, suggesting conservation of the developmental role of these family members over the course of evolution. Our phylogenetic analysis of the expanded LSF/GRH family (including other previously unrecognized proteins/ESTs) suggests that the structural and functional dichotomy of this family dates back more than 700 million years, i.e. to the time when the first multicellular organisms are thought to have arisen.

    The epidermal growth factor (EGF) family of receptor tyrosine kinases consists of four members: EGFR (HER1/ErbB1), HER2/neu (ErbB2), HER3 (ErbB3) and HER4 (ErbB4). Receptor activation via ligand binding leads to downstream signaling that influence cell proliferation, angiogenesis, invasion and metastasis. Aberrant expression or activity of EGFR and HER2 have been strongly linked to the etiology of several human epithelial cancers including but not limited to head and neck squamous cell carcinoma (HNSCC), non-small cell lung cancer (NSCLC), colorectal cancer (CRC), and breast cancer. With this, intense efforts have been made to inhibit the activity of the EGFR and HER2 by designing antibodies against the ligand binding domains (cetuximab, panitumumab and trastuzumab) or small molecules against the tyrosine kinase domains (erlotinib, gefitinib, and lapatinib). Both approaches have shown considerable clinical promise. However, increasing evidence suggests that the majority of patients do not respond to these therapies, and those who show initial response ultimately become refractory to treatment. While mechanisms of resistance to tyrosine kinase inhibitors have been extensively studied, resistance to monoclonal antibodies is less well understood, both in the laboratory and in the clinical setting. In this review, we discuss resistance to antibody-based therapies against the EGFR and HER2, similarities between these resistance profiles, and strategies to overcome resistance to HER family targeting monoclonal antibody therapy.

  16. Evolutionary origin of the Scombridae (tunas and mackerels: members of a paleogene adaptive radiation with 14 other pelagic fish families.

    Full Text Available Uncertainties surrounding the evolutionary origin of the epipelagic fish family Scombridae (tunas and mackerels are symptomatic of the difficulties in resolving suprafamilial relationships within Percomorpha, a hyperdiverse teleost radiation that contains approximately 17,000 species placed in 13 ill-defined orders and 269 families. Here we find that scombrids share a common ancestry with 14 families based on (i bioinformatic analyses using partial mitochondrial and nuclear gene sequences from all percomorphs deposited in GenBank (10,733 sequences and (ii subsequent mitogenomic analysis based on 57 species from those targeted 15 families and 67 outgroup taxa. Morphological heterogeneity among these 15 families is so extraordinary that they have been placed in six different perciform suborders. However, members of the 15 families are either coastal or oceanic pelagic in their ecology with diverse modes of life, suggesting that they represent a previously undetected adaptive radiation in the pelagic realm. Time-calibrated phylogenies imply that scombrids originated from a deep-ocean ancestor and began to radiate after the end-Cretaceous when large predatory epipelagic fishes were selective victims of the Cretaceous-Paleogene mass extinction. We name this clade of open-ocean fishes containing Scombridae "Pelagia" in reference to the common habitat preference that links the 15 families.

    To describe the extent to which nursing homes engaged families in antipsychotic initiation decisions in the year before surveyor guidance revisions were implemented. Mixed-methods study based on semistructured interviews. U.S. nursing homes (N = 20) from five CMS regions (III, IV, VI, VIII, IX). Family members of nursing home residents (N = 41). Family member responses to closed- and open-ended questions regarding involvement in resident care and antipsychotic initiation. Two researchers used a content analytical approach to code open responses to themes of family involvement in behavior management, decision-making, knowledge of risks and benefits, and informed consent. Fifty-four percent of family members felt highly involved in decisions about behavior management. Forty-two percent recalled being asked how to manage resident behavior without medication, and 17% recalled receipt of information about antipsychotic risks and benefits. Sixty-six percent felt highly involved in the process of initiating antipsychotic medication; 24% reported being asked for input into the antipsychotic initiation decision and knowing before the antipsychotic was started. Under existing federal regulations but before guidance revisions were implemented in 2013, more than 40% of families reported being involved in nonpharmacological behavior management of family members, but fewer than one in four reported being involved throughout the entire antipsychotic prescribing process. Interventions that standardize family engagement and promote adherence to existing federal regulations are needed. This discussion builds on these findings to weigh the policy options of greater enforcement of existing regulations versus enactment of new legislation to address this challenging issue. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

    Members of the SREBP family of transcription factors control cholesterol and lipid homeostasis and play important roles during adipocyte differentiation. The transcriptional activity of SREBPs is dependent on the coactivators p300 and CBP. We now present evidence that SREBPs are acetylated by the intrinsic acetyltransferase activity of p300 and CBP. In SREBP1a, the acetylated lysine residue resides in the DNA-binding domain of the protein. Coexpression with p300 dramatically increases the expression of both SREBP1a and SREBP2, and this effect is dependent on the acetyltransferase activity of p300, indicating that acetylation of SREBPs regulates their stability. Indeed, acetylation or mutation of the acetylated lysine residue in SREBP1a stabilizes the protein. We demonstrate that the acetylated residue in SREBP1a is also targeted by ubiquitination and that acetylation inhibits this process. Thus, our studies define acetylation-dependent stabilization of transcription factors as a novel mechanism for coactivators to regulate gene expression.

    Innate immunity in shrimp is important in resisting bacterial infection. The NF-κB pathway is pivotal in such an immune response. This study cloned and functionally characterized the solute carrier family (SLC) 15 member A 4 (LvSLC15A4) gene in Litopenaeus vannamei. The open reading frame of LvSLC15A4 is 1, 902 bp long and encodes a putative 633-amino acid protein, which is localized in the plasma membrane and intracellular vesicular compartments. Results of the reporter gene assay showed that LvSLC15A4 upregulated NF-κB target genes, including the immediate-early gene 1 of white spot syndrome virus, as well as several antimicrobial peptide genes, such as pen4, CecA, AttA, and Mtk in S2 cells. Moreover, knocked-down expression of LvSLC15A4 reduced pen4 expression in L. vannamei. LvSLC15A4 down-regulation also increased the cumulative mortality of Vibrio parahemolyticus-infected L. vannamei. Furthermore, LvSLC15A4 expression was induced by unfolded protein response (UPR) in L. vannamei hematocytes. These results suggest that LvSLC15A4 participates in L. vannamei innate immunity via the NF-κB pathway and thus may be related to UPR.

    Full Text Available B7x (B7-H4 or B7S1 is a member of the B7 family that can inhibit T cell function. B7x protein is absent in most normal human tissues and immune cells, but it is overexpressed in human cancers and often correlates with negative clinical outcome. The expression pattern and function of B7x suggest that it may be a potent immunosuppressive pathway in human cancers. Here, we determined the crystal structure of the human B7x immunoglobulin variable (IgV domain at 1.59 Å resolution and mapped the epitopes recognized by monoclonal antibodies. We developed an in vivo system to screen therapeutic monoclonal antibodies against B7x and found that the clone 1H3 significantly inhibited growth of B7x-expressing tumors in vivo via multiple mechanisms. Furthermore, the surviving mice given 1H3 treatment were resistant to tumor rechallenge. Our data suggest that targeting B7x on tumors is a promising cancer immunotherapy and humanized 1H3 may be efficacious for immunotherapy of human cancers.

    Here we performed structural and biochemical analyses on the TK2285 gene product, an uncharacterized protein annotated as a member of the ribokinase family, from the hyperthermophilic archaeon Thermococcus kodakarensis. The three-dimensional structure of the TK2285 protein resembled those of previously characterized members of the ribokinase family including ribokinase, adenosine kinase, and phosphofructokinase. Conserved residues characteristic of this protein family were located in a cleft of the TK2285 protein as in other members whose structures have been determined. We thus examined the kinase activity of the TK2285 protein toward various sugars recognized by well characterized ribokinase family members. Although activity with sugar phosphates and nucleosides was not detected, kinase activity was observed toward d-allose, d-lyxose, d-tagatose, d-talose, d-xylose, and d-xylulose. Kinetic analyses with the six sugar substrates revealed high Km values, suggesting that they were not the true physiological substrates. By examining activity toward amino sugars, sugar alcohols, and disaccharides, we found that the TK2285 protein exhibited prominent kinase activity toward myo-inositol. Kinetic analyses with myo-inositol revealed a greater kcat and much lower Km value than those obtained with the monosaccharides, resulting in over a 2,000-fold increase in kcat/Km values. TK2285 homologs are distributed among members of Thermococcales, and in most species, the gene is positioned close to a myo-inositol monophosphate synthase gene. Our results suggest the presence of a novel subfamily of the ribokinase family whose members are present in Archaea and recognize myo-inositol as a substrate.

    Full Text Available The aim of the current study was to explore the impact of schizophrenia on the life of the patient and his family, in particular, which problems people with schizophrenia and their families face. We applied a qualitative research strategy and method of semi-structured interview. Qualitative analysis of the data demonstrated barriers in the working and financial areas of life of people with schizophrenia. In addition, schizophrenia negatively affects social interactions of patients which lead to their social isolation which is also derived from barriers at work. Families with this kind of patient suffer mainly in the economic sphere of life with the necessity to leave the job and take care of an ill member. These families also suffer from isolation, restriction of social contacts, reduction of free-time activities, and many other problems included within the barriers in social interactions. Family members suffer psychological stress and they badly cope with the situation if the ill member is hospitalized. In addition, the family meets with the structural discrimination in the form of lack of information about the disease, lack of day care centres network and similar barriers in communication with physicians and the other professionals.

    Families who are socially excluded are vulnerable to problems related to the use of psychoactive substances. This study aimed to identify the perception regarding drugs use among families that lived in extreme poverty and participated in a social-educational group in the suburbs of a city in the interior of São Paulo State. A survey-like quantitative study was conducted involving 70 members of families who participated in the social-educational groups of the Program for Integral Assistance to the Family. Results indicated that 67 (95.7%) of the subjects were married, at an average age of 37, most of them had not completed grade school, and were unemployed. Fifty five (78.6%) had a family member who used alcohol, fifty two (74,3%) smoked, and twenty three (32.9%) used some kind of illicit drug. The results also showed that living with a relative who was a drug user was perceived as problem that elicited feelings resentment, but also conformism on the part of other family members.

    The aim of this study was to investigate what the presence of family members meant to patients in intensive care units. The study employed a qualitative approach with semi-structured interviews and qualitative content analysis. Eleven intensive care patients were interviewed at a university hospital in Norway. The results of the study indicated that the patients desired some limitation of visitors' presence and preferred visits only from those who were closest in daily life. Visits had a variety of functions for intensive care patients, including promoting support for patients and families. However, visits also caused stress for patients and worries about creating stress for family members. The patients' requirements for information differed. The findings suggest that information to the families is important for the patients need for reality orientation. Visits in intensive care units and information to the families have mutual importance for the patients and their families. The study supports prior claims that flexible visiting routines are challenging for ICU nurses. A dialogue with the families is recommended in order to find a balance between the social support and the stress caused by visits. This puts the families in a better position to give support to the patients during recovery.

    RNA-directed DNA methylation (RdDM) is essential for de novo DNA methylation in higher plants, and recent reports established novel elements of this silencing pathway in the model organism Arabidopsis thaliana. Involved in de novo DNA methylation 2 (IDN2) and the closely related factor of DNA methylation (FDM) are members of a plant-specific family of dsRNA-binding proteins characterized by conserved XH/XS domains and implicated in the regulation of RdDM at chromatin targets. Genetic analyses have suggested redundant as well as non-overlapping activities for different members of the gene family. However, detailed insights into the function of XH/XS-domain proteins are still elusive. By the generation and analysis of higher-order mutant combinations affected in IDN2 and further members of the gene family, we have provided additional evidence for their redundant activity. Distinct roles for members of the XH/XS-domain gene family were indicated by differences in their expression and subcellular localization. Fluorescent protein-tagged FDM genes were expressed either in nuclei or in the cytoplasm, suggestive of activities of XH/XS-domain proteins in association with chromatin as well as outside the nuclear compartment. In addition, we observed altered location of a functional FDM1-VENUS reporter from the nucleus into the cytoplasm under conditions when availability of further FDM proteins was limited. This is suggestive of a mechanism by which redistribution of XH/XS-domain proteins could compensate for the loss of closely related proteins.

    The stathmin (STMN) family of tubulin-binding phosphoproteins are critical regulators of interphase microtubule dynamics and organization in a broad range of cellular processes. c-Jun N-terminal kinase (JNK) signalling to STMN family proteins has been implicated specifically in neuronal maturation, degeneration and cell stress responses more broadly. Previously, we characterized mechanisms underlying JNK phosphorylation of STMN at proline-flanked serine residues (Ser25 and Ser38) that are conserved across STMN-like proteins. In this study, we demonstrated using in vitro kinase assays and alanine replacement of serine residues that JNK phosphorylated the STMN-like domain (SLD) of SCG10 on Ser73, consistent with our previous finding that STMN Ser38 was the primary JNK target site. In addition, we confirmed that a JNK binding motif ((41)KKKDLSL(47)) that facilitates JNK targeting of STMN is conserved in SCG10. In contrast, SCLIP was phosphorylated by JNK primarily on Ser60 which corresponds to Ser25 on STMN. Moreover, although the JNK-binding motif identified in STMN and SCG10 was not conserved in SCLIP, JNK phosphorylation of SCLIP was inhibited by a substrate competitive peptide (TI-JIP) highlighting kinase-substrate interaction as required for JNK targeting. Thus, STMN and SCG10 are similarly targeted by JNK but there are clear differences in JNK recognition and phosphorylation of the closely related family member, SCLIP.

    Similar to many developed nations, older people living in residential aged care homes in Australia and the staff who care for them have become increasingly multicultural. This cultural diversity adds challenges for residents in adapting to the care home. This study explores: (i) residents' and family members' perceptions about staff and cultural diversity, and (ii) culturally and linguistically diverse residents' and family members' experiences. An interpretive study design employing a thematic analysis was applied. Twenty-three residents and seven family members participated in interviews. Four themes were identified from interpreting residents and family members' perceptions of the impact of cultural diversity on their adaptation to aged care homes: (i) perceiving diversity as an attraction; (ii) adapting to cross-cultural communication; (iii) adjusting to diet in the residential care home; and (iv) anticipating individualized psychosocial interactions. The findings have implications for identifying strategies to support staff from all cultural backgrounds in order to create a caring environment that facilitates positive relationships with residents and supports residents to adjust to the care home.

  3. Chipmunk parvovirus is distinct from members in the genus Erythrovirus of the family Parvoviridae.

    Zhaojun Chen

    Full Text Available The transcription profile of chipmunk parvovirus (ChpPV, a tentative member of the genus Erythrovirus in the subfamily Parvovirinae of the family Parvoviridae, was characterized by transfecting a nearly full-length genome. We found that it is unique from the profiles of human parvovirus B19 and simian parvovirus, the members in the genus Erythrovirus so far characterized, in that the small RNA transcripts were not processed for encoding small non-structural proteins. However, like the large non-structural protein NS1 of the human parvovirus B19, the ChpPV NS1 is a potent inducer of apoptosis. Further phylogenetic analysis of ChpPV with other parvoviruses in the subfamily Parvovirinae indicates that ChpPV is distinct from the members in genus Erythrovirus. Thus, we conclude that ChpPV may represent a new genus in the family Parvoviridae.

Prospective study conducted from August 2003 to May 2004. Tertiary care university teaching hospital. All fourth-year students were eligible to participate during their mandatory four-week critical care medicine clerkship. The educational intervention focused on the initial meeting with the family member of an ICU patient and included formal teaching of a communication framework followed by a practice session with an actor playing the role of a standardized family member of a fictional patient. At the beginning of the critical care medicine rotation, the intervention group received the educational session, whereas students in the control group did not. At the end of each critical care medicine rotation, all students interacted with a different standardized family member portraying a different fictional scenario. Sessions were videotaped and were scored by an investigator blinded to treatment assignment using a standardized grading tool across four domains: a) introduction; b) gathering information; c) imparting information; and d) setting goals and expectations. A total of 106 (97% of eligible) medical students agreed to participate in the study. The total mean score as well as the scores for the gathering information, imparting information, setting goals, and expectations domains for the intervention group were significantly higher than for the control group (p communication skills of fourth-year medical students can be improved by teaching and then practicing a framework for an initial ICU communication episode with a standardized family member.

    1988-04-15

    Patients with microscopic hematuria are generally referred for urologic investigation. The authors describe 30 patients with normal renal function referred to our clinic during the years 1970 through 1987 for evaluation of hematuria, usually microscopic, in whom prior urologic and radiological studies had failed to determine the cause of bleeding. Urinary sediment from the patients and first-degree relatives revealed hemoglobin and red blood cell casts; the inheritance pattern was consistent with autosomal dominant transmission. During follow-up for up to 18 years, renal function remained normal, thus confirming the diagnosis of benign familial hematuria. Immunoglobulin A nephropathy and Alport's syndrome were less common than benign familial hematuria and could be differentiated from it by history, physical examination, and routine laboratory testing. Since benign familial hematuria is a common disorder in adults with hematuria and normal renal function, urinary sediment from patients and family members should be examined before extensive urologic and radiological procedures are performed.

    Carbonic anhydrases (CA) are ubiquitous, and their involvement in diseases such as hypertension, diabetes, and glaucoma is well known. Most members of this family of metalloenzymes convert carbon dioxide to bicarbonate with the help of a Zn(2+) cofactor. While the expression patterns and kinetic activities of many of these isozymes have been studied, little is known about the differences in the conservation patterns of individual residues. To better understand the molecular evolution of the CA gene family, we created multiple sequence alignments and analyzed the selection pressure (dN/dS ratios) on surface and active site residues in 248 mammalian sequences of the 14 known family members. Using the values found for amino acids of known functional importance (i.e. the three histidines that bind the zinc cofactor) as our baseline, we were able to identify other regions of possible structural and functional importance.

    2008-01-01

    The neurotrophin and glial cell line-derived neurotrophic factor (GDNF) family of growth factors have been extensively studied because of their proven ability to regulate development of the peripheral nervous system. The neurotrophin family,which includes nerve growth factor (NGF), NT-3, NT4/5 and BDNF, is also known for its ability to regulate the function of adult sensory neurons. Until recently, little was known concerning the role of the GNDF-family (that includes GDNF, artemin, neurturin and persephin) in adult sensory neuron function. Here we describe recent data that indicates that the GDNF family can regulate sensory neuron function, that some of its members are elevated in inflammatory pain models and that application of these growth factors produces pain in vivo. Finally we discuss how these two families of growth factors may converge on a single membrane receptor, TRPV 1, to produce long-lasting hyperalgesia.

  11. Metastasis suppressor microRNA-335 targets the formin family of actin nucleators.

    Directory of Open Access Journals (Sweden)

    Jennifer Lynch

    Full Text Available MiRNAs can have pleiotropic effects by targeting multiple genes belonging to diverse signalling networks. Alternatively, miRNAs can enhance the potency of their cellular effects by targeting multiple genes within the same genetic pathway. Previously, we and others have demonstrated that miR-335 is a potent suppressor of tumour cell migration, invasion and metastasis, in part by targeting several genes involved in these cellular processes, including ROCK1, MAPK1, LRG1, SP1 and SOX4. Here, we demonstrate that direct targeting of multiple members of the formin family of actin nucleators contributes to the inhibitory effects of miR-335 in neuroblastoma cells. We demonstrate that miR-335 regulates the expression of at least five formin family members and validate three family members, FMNL3, FMN2 and DAAM2, as direct targets of miR-335. The contribution of the formin family genes to cancer progression and metastasis has recently begun to emerge and here we demonstrate for the first time the ability of FMN2 and DAAM2 to regulate tumour cell migration and invasion, using siRNA-mediated inhibition of each of these formin genes. Finally, we demonstrate that the formin genes, in particular FMNL3, are responsible for the protrusion of actin-rich filopodia structures that contribute to the enhanced migratory and invasive potential associated with reduced expression of miR-335. Thus, direct targeting of the formin family contributes to the metastasis suppressing abilities of miR-335 by providing a direct regulatory link to the actin assembly machinery of the cell. We conclude that miR-335 is a master regulator of tumour cell migration and invasion by directly targeting a plethora of genes that effectively control cell migratory processes.

We demonstrate that miR-335 regulates the expression of at least five formin family members and validate three family members, FMNL3, FMN2 and DAAM2, as direct targets of miR-335. The contribution of the formin family genes to cancer progression and metastasis has recently begun to emerge and here we demonstrate for the first time the ability of FMN2 and DAAM2 to regulate tumour cell migration and invasion, using siRNA-mediated inhibition of each of these formin genes. Finally, we demonstrate that the formin genes, in particular FMNL3, are responsible for the protrusion of actin-rich filopodia structures that contribute to the enhanced migratory and invasive potential associated with reduced expression of miR-335. Thus, direct targeting of the formin family contributes to the metastasis suppressing abilities of miR-335 by providing a direct regulatory link to the actin assembly machinery of the cell. We conclude that miR-335 is a master regulator of tumour cell migration and invasion by directly targeting a plethora of genes that effectively control cell migratory processes. PMID:24223803

    BAHD acyltransferases, named after the first four biochemically characterized enzymes of the group, are plant-specific enzymes that catalyze the transfer of coenzyme A-activated donors onto various acceptor molecules. They are responsible for the synthesis in plants of a myriad of secondary metabolites, some of which are beneficial for humans either as therapeutics or as specialty chemicals such as flavors and fragrances. The production of pharmaceutical, nutraceutical and commodity chemicals using engineered microbes is an alternative, green route to energy-intensive chemical syntheses that consume petroleum-based precursors. However, identification of appropriate enzymes and validation of their functional expression in heterologous hosts is a prerequisite for the design and implementation of metabolic pathways in microbes for the synthesis of such target chemicals. As a result, for the synthesis of valuable metabolites in the yeast Saccharomyces cerevisiae, we selected BAHD acyltransferases based on their preferred donor and acceptor substrates. In particular, BAHDs that use hydroxycinnamoyl-CoAs and/or benzoyl-CoA as donors were targeted because a large number of molecules beneficial to humans belong to this family of hydroxycinnamate and benzoate conjugates. The selected BAHD coding sequences were synthesized and cloned individually on a vector containing the Arabidopsis gene At4CL5, which encodes a promiscuous 4-coumarate:CoA ligase active on hydroxycinnamates and benzoates. The various S. cerevisiae strains obtained for co-expression of At4CL5 with the different BAHDs effectively produced a wide array of valuable hydroxycinnamate and benzoate conjugates upon addition of adequate combinations of donors and acceptor molecules. In particular, we report here for the first time the production in yeast of rosmarinic acid and its derivatives, quinate hydroxycinnamate esters such as chlorogenic acid, and glycerol hydroxycinnamate esters

    Age-related hearing loss (ARHL) is characterized by an age-dependent decline of auditory function characterized by with loss of sensory hair cells, spiral ganglion neurons, and stria vascularis (SV) cells in the cochlea of the inner ear. Aging and age-related diseases result from accumulated oxidative damage caused by reactive oxygen species (ROS) generated by mitochondria. The isocitrate dehydrogenase (IDH) family includes three enzymes in human cells: IDH1, IDH2, and IDH3. Although all three enzymes catalyze the same enzymatic reaction, that is, oxidative decarboxylation of isocitrate to produce α-ketoglutarate, each IDH enzyme has unique features. We identified and characterized IDH expression in the cochlea and vestibule of the murine inner ear. We examined the mRNA expression levels of Idh family members in the cochlea and vestibule using reverse transcription-PCR (RT-PCR) and detected expression of IDH family members in both tissues. We also used immunohistochemistry to localize IDH family members within the cochlea and vestibule of the adult mouse inner ear. IDH1 was detected throughout the cochlea. IDH2 was expressed specifically in the hair cells, spiral ganglion, and stria vascularis. IDH3α was found in the cell bodies of neurons of the spiral ganglion, the stria vascularis, and in types II, IV, and V cells of the spiral ligament in a pattern that resembled the location of the Na(+), K(+)-ATPase ion channel. We postulate that the IDH family participates in transporting K(+) ions in the cochlea. In the vestibule, all IDH family members were detected in both hair cells and the vestibular ganglion. We hypothesize that IDH1, IDH2, and IDH3 function to protect proteins in the inner ear from oxidative stress during K(+) recycling.

    Family members (FMs) often provide support to patients, regularly attend cancer consultations and are often involved in medical decision-making. Limited research has been conducted to date to understand patients' and FMs' perceptions about family involvement in cancer consultations. Therefore, this study aimed to qualitatively explore the attitudes and experiences of Australian cancer patients and FMs regarding (1) family attendance at consultations, (2) family roles in consultations and (3) the challenges of family involvement. Thirty patients and 33 FMs, recruited through either a tertiary metropolitan oncology clinic or national cancer patient advocacy group, participated in semi-structured interviews. Interviews were transcribed and qualitatively analysed using Framework analysis methods. Four relevant themes were identified: (1) negotiating family involvement, (2) attitudes towards the roles FMs assume, (3) challenges of family involvement and (4) family-clinician interactions. Overall, patients appreciated family involvement and valued FMs' provision of emotional and informational support, and FMs also found benefit from participating in consultations. Some patients appreciated their FM assuming the role of 'messenger' between the consultation and extended family. However, a number of challenges were also reported by patients (e.g. maintaining privacy, mismatched patient-family information needs) and FMs (e.g. emotional toll of supportive roles, negative behaviours of clinicians towards FMs). FMs appear to make valuable contributions to cancer consultations, and their presence can benefit both the patient and the FM themselves in many ways. However, for some FMs, attending consultations can be challenging. Study findings point to the need for psychosocial support addressing FMs' needs and the development of communication strategies for oncology clinicians to positively engage with FMs. Further research is needed in these areas.

(b) To evaluate environmental contamination with antineoplastic drugs via excreta of patients in the home setting. (c) To evaluate exposure of family members to antineoplastic drugs by measuring the drugs in their urine during the 48 h after completion of the chemotherapy by the patients. Two patients were administered cyclophosphamide by i.v. bolus injection. One patient was administered 5-fluorouracil by i.v. bolus injection and thereafter immediately administered the same drug by continuous infusion for 46 h. Urine samples from the patients administered cyclophosphamide and their family members, and wipe samples from their home environment, were analysed for the unchanged form of cyclophosphamide. For 5-fluorouracil, the urine samples from the patient and the family member were analysed for the 5-fluorouracil metabolite α-fluoro-β-alanine. Wipe samples were analysed for 5-fluorouracil. Drugs were detected and quantified with gas chromatography in tandem with mass spectroscopy-mass spectroscopy or by high-performance liquid chromatography with ultraviolet-light detection. A total of 35 and 16 urine samples were collected from the three patients and their family members, respectively. The drugs were detected in all samples. Cyclophosphamide was detected at levels of 0.03-7.34 ng/cm(2) in 8 of the 12 wipe samples obtained from the homes of the patients administered cyclophosphamide. For the patient administered 5-fluorouracil, drug levels in his home environment were below the limit of detection. We demonstrated contamination of the home setting and exposure of family members to cyclophosphamide via the excreta of outpatient receiving chemotherapy. Exposure of the family member of the patient administered 5-fluorouracil was also demonstrated. These findings indicate the

    Chicken avidin family consists of several proteins which bind a small vitamin, D-biotin. One of these proteins, avidin, is a widely used biological tool in the life sciences. The other members of the family are avidin-related proteins (AVRs). Avidin is thought to be an antimicrobial protein whereas the biological role of AVRs is not known. AVRs have been characterised only as recombinant proteins.The aim of this study was to characterise the structural and functional features of AVRs, especia...

  19. Differential expression of three members of the multidomain adhesion CCp family in Babesia bigemina, Babesia bovis and Theileria equi.

    Directory of Open Access Journals (Sweden)

    Reginaldo G Bastos

    Full Text Available Members of the CCp protein family have been previously described to be expressed on gametocytes of apicomplexan Plasmodium parasites. Knocking out Plasmodium CCp genes blocks the development of the parasite in the mosquito vector, making the CCp proteins potential targets for the development of a transmission-blocking vaccine. Apicomplexans Babesia bovis and Babesia bigemina are the causative agents of bovine babesiosis, and apicomplexan Theileria equi causes equine piroplasmosis. Bovine babesiosis and equine piroplasmosis are the most economically important parasite diseases that affect worldwide cattle and equine industries, respectively. The recent sequencing of the B. bovis and T. equi genomes has provided the opportunity to identify novel genes involved in parasite biology. Here we characterize three members of the CCp family, named CCp1, CCp2 and CCp3, in B. bigemina, B. bovis and T. equi. Using B. bigemina as an in vitro model, expression of all three CCp genes and proteins was demonstrated in temperature-induced sexual stages. Transcripts for all three CCp genes were found in vivo in blood stages of T. equi, and transcripts for CCp3 were detected in vivo in blood stages of B. bovis. However, no protein expression was detected in T. equi blood stages or B. bovis blood stages or B. bovis tick stages. Collectively, the data demonstrated a differential pattern of expression of three orthologous genes of the multidomain adhesion CCp family by B. bigemina, B. bovis and T. equi. The novel CCp members represent potential targets for innovative approaches to control bovine babesiosis and equine piroplasmosis.

    We previously showed that about 80% of breast cancer patients at high risk to carry mutation in BRCA genes presented at least one polymorphism in these genes which resulted potentially harmful by in silico analysis. In the present paper, the genealogic transmission of those polymorphic coding and noncoding variants of BRCA genes in family's members has been investigated. Thirty families, enrolled within the Genetic Counselling Program of our Institute, with probands and at least one-first degree relative (n = 67 family members) available, have been studied for both BRCA1 and BRCA2 pathological mutation and polymorphic variants' transmission. Ten and 6 probands carried Mendelian transmitted mutations in BRCA1 and BRCA2, respectively. Polymorphic coding and noncoding variants were transmitted in each family's relatives with a frequency ranging from 42 to 100%, with similar rate for each SNP in mutated and nonmutated families with the only exception of BRCA1 K1183R significantly more frequent in mutated families (P = 0.004); conversely, this SNP and BRCA2 N372H, were more frequently present in breast cancer relatives belonging to families in which pathological BRCA mutations were not present. Furthermore, specific haplotypes were transmitted in all relatives as BRCA1 871Leu-1038Gly, present in both BRCA mutated and nonmutated families, while BRCA2 289His-991Asp-IVS14+53 C>T present only in BRCAX families suggesting the harmful role of these SNPs. In conclusion, analysis of SNPs maps and modality of their transmission could identify further susceptibility markers and provide a basis for a better DNA-based cancer classification.

  1. Stress regulated members of the plant organic cation transporter family are localized to the vacuolar membrane

    2008-07-01

    Full Text Available Abstract Background In Arabidopsis six genes group into the gene family of the organic cation transporters (OCTs. In animals the members of the OCT-family are mostly characterized as polyspecific transporters involved in the homeostasis of solutes, the transport of monoamine neurotransmitters and the transport of choline and carnitine. In plants little is known about function, localisation and regulation of this gene family. Only one protein has been characterized as a carnitine transporter at the plasma membrane so far. Findings We localized the five uncharacterized members of the Arabidopsis OCT family, designated OCT2-OCT6, via GFP fusions and protoplast transformation to the tonoplast. Expression analysis with RNA Gel Blots showed a distinct, organ-specific expression pattern of the individual genes. With reporter gene fusion of four members we analyzed the tissue specific distribution of OCT2, 3, 4, and 6. In experiments with salt, drought and cold stress, we could show that AtOCT4, 5 and 6 are up-regulated during drought stress, AtOCT3 and 5 during cold stress and AtOCT 5 and 6 during salt stress treatments. Conclusion Localisation of the proteins at the tonoplast and regulation of the gene expression under stress conditions suggests a specific role for the transporters in plant adaptation to environmental stress.

  2. Still Searching: A Meta-Synthesis of a Good Death from the Bereaved Family Member Perspective

    Full Text Available The concept of a good death continues to receive attention in end-of-life (EOL scholarship. We sought to continue this line of inquiry related to a good death by conducting a meta-synthesis of published qualitative research studies that examined a good death from the bereaved family member’s perspective. Results of the meta-synthesis included 14 articles with 368 participants. Based on analysis, we present a conceptual model called The Opportunity Model for Presence during the EOL Process. The model is framed in socio-cultural factors, and major themes include EOL process engagement with categories of healthcare participants, communication and practical issues. The second theme, (discontinuity of care, includes categories of place of care, knowledge of family member dying and moment of death. Both of these themes lead to perceptions of either a good or bad death, which influences the bereavement process. We argue the main contribution of the model is the ability to identify moments throughout the interaction where family members can be present to the EOL process. Recommendations for healthcare participants, including patients, family members and clinical care providers are offered to improve the quality of experience throughout the EOL process and limitations of the study are discussed.

  3. Human embryonic stem cells express elevated levels of multiple pro-apoptotic BCL-2 family members.

    David T Madden

    Full Text Available Two of the greatest challenges in regenerative medicine today remain (1 the ability to culture human embryonic stem cells (hESCs at a scale sufficient to satisfy clinical demand and (2 the ability to eliminate teratoma-forming cells from preparations of cells with clinically desirable phenotypes. Understanding the pathways governing apoptosis in hESCs may provide a means to address these issues. Limiting apoptosis could aid scaling efforts, whereas triggering selective apoptosis in hESCs could eliminate unwanted teratoma-forming cells. We focus here on the BCL-2 family of proteins, which regulate mitochondrial-dependent apoptosis. We used quantitative PCR to compare the steady-state expression profile of all human BCL-2 family members in hESCs with that of human primary cells from various origins and two cancer lines. Our findings indicate that hESCs express elevated levels of the pro-apoptotic BH3-only BCL-2 family members NOXA, BIK, BIM, BMF and PUMA when compared with differentiated cells and cancer cells. However, compensatory expression of pro-survival BCL-2 family members in hESCs was not observed, suggesting a possible explanation for the elevated rates of apoptosis observed in proliferating hESC cultures, as well as a mechanism that could be exploited to limit hESC-derived neoplasms.

    Full Text Available OBJECTIVES: Family members of patients in a vegetative state have relatively high rates of anxiety and distress. It is important to recognize the problems faced by this population and apply psychological interventions to help them. This exploratory study describes the psychological stress experienced by family members of patients in a vegetative state. We discuss the effectiveness of a psychological crisis intervention directed at this population and offer suggestions for future clinical work. METHODS: A total of 107 family members of patients in a vegetative state were included in the study. The intervention included four steps: acquisition of facts about each family, sharing their first thoughts concerning the event, assessment of their emotional reactions and developing their coping abilities. The Symptom Check List-90 was used to evaluate the psychological distress of the participants at baseline and one month after the psychological intervention. Differences between the Symptom Check List-90 scores at the baseline and follow-up evaluations were analyzed. RESULTS: All participants in the study had significantly higher Symptom Check List-90 factor scores than the national norms at baseline. There were no significant differences between the intervention group and the control group at baseline. Most of the Symptom Check List-90 factor scores at the one-month follow-up evaluation were significantly lower than those at baseline for both groups; however, the intervention group improved significantly more than the control group on most subscales, including somatization, obsessive-compulsive behavior, depression, and anxiety. CONCLUSION: The results of this study indicate that the four-step intervention method effectively improves the mental health of the family members who received this treatment and lessens the psychological symptoms of somatization, obsessive-compulsive behavior, depression and anxiety.

    Advance care planning (ACP) is the process by which patients, together with their physician and loved ones, establish preferences for future care. Because previous research has shown that relatives play a considerable role in end-of-life care decisions, it is important to understand how family members are involved in this process. To gain understanding of the involvement of family members in ACP for older people near the end of life by exploring their views and experiences concerning this process. This was a qualitative research study, done with semistructured interviews. Twenty-one family members were recruited from three geriatric settings in Flanders, Belgium. The data were analyzed using the constant comparative method as proposed by the grounded theory. Family members took different positions in the ACP process depending on how much responsibility the family member wanted to take and to what extent the family member felt the patient expected him/her to play a part. The position of family members on these two dimensions was influenced by several factors, namely acknowledgment of the imminent death, experiences with death and dying, opinion about the benefits of ACP, burden of initiating conversations about death and dying, and trust in health care providers. Furthermore, the role of family members in ACP was embedded in the existing relationship patterns. This study provides insight into the different positions of family members in the end-of-life care planning of older patients with a short life expectancy. It is important for health care providers to understand the position of a family member in the ACP of the patient, take into account that family members may experience an active role in ACP as burdensome, and consider existing relationship patterns.

    Conclusions: The more severe pathogenic condition of the patient, the heavier the psychological pressure is on their family member caregivers. Medical staff should therefore pay close attention to the psychological health of family caregivers of TBI patients, especially family caregivers of critical cases. Interventions should be accordingly designed and conducted to meet the needs of family caregivers.

    Chlamydiae sp. are obligate intracellular pathogens that cause a variety of diseases in humans. Adhesion of the infectious elementary body to the eukaryotic host cell is a pivotal step in chlamydial pathogenesis. Here we describe the characterization of members of the polymorphic membrane protein family (Pmp), the largest protein family (with up to 21 members) unique to Chlamydiaceae. We show that yeast cells displaying Pmp6, Pmp20 or Pmp21 on their surfaces, or beads coated with the recombinant proteins, adhere to human epithelial cells. A hallmark of the Pmp protein family is the presence of multiple repeats of the tetrapeptide motifs FxxN and GGA(I, L, V) and deletion analysis shows that at least two copies of these motifs are needed for adhesion. Importantly, pre-treatment of human cells with recombinant Pmp6, Pmp20 or Pmp21 protein reduces infectivity upon subsequent challenge with Chlamydia pneumoniae and correlates with diminished attachment of Chlamydiae to target cells. Antibodies specific for Pmp21 can neutralize infection in vitro. Finally, a combination of two different Pmp proteins in infection blockage experiments shows additive effects, possibly suggesting similar functions. Our findings imply that Pmp6, Pmp20 and Pmp21 act as adhesins, are vital during infection and thus represent promising vaccine candidates.

    The neural IgCAM family of cell adhesion molecules, which includes NCAM and related molecules, has evolved via gene duplication and alternative splicing to allow for a wide range of isoforms with distinct functions and homophilic binding properties. A search for neural IgCAMs in ascidians (Ciona intestinalis, Ciona savignyi, and Phallusia mammillata) has identified a novel set of truncated family members that, unlike the known members, lack fibronectin III domains and consist of only repeated Ig domains. Within the tunicates this form appears to be unique to the ascidians, and it was designated ACAM, for Ascidian Cell Adhesion Molecule. In C. intestinalis ACAM is expressed in the developing neural plate and neural tube, with strongest expression in the anterior sensory vesicle precursor. Unlike the two other conventional neural IgCAMs in C. intestinalis, which are expressed maternally and throughout the morula and blastula stages, ACAM expression initiates at the gastrula stage. Moreover, C. intestinalis ACAM is a target of the homeodomain transcription factor OTX, which plays an essential role in the development of the anterior central nervous system. Morpholino (MO) knockdown shows that ACAM is required for neural tube closure. In MO-injected embryos neural tube closure was normal caudally, but the anterior neuropore remained open. A similar phenotype was seen with overexpression of a secreted version of ACAM. The presence of ACAM in ascidians highlights the diversity of this gene family in morphogenesis and neurodevelopment.

    Psymberin is the only member of the pederin natural product family that contains a dihydroisocoumarin side chain. Structural modifications of psymberin uncoupled inhibition of protein translation from cytotoxicity, suggesting that psymberin has more than one bioactivity. A forward genetic screen in Caenorhabditis elegans was conducted to identify the molecular target(s) of psymberin. Multiple independent psymberin-resistant mutants were isolated, each containing the same point mutation in a gene encoding a ribosomal protein. However, a psymberin-resistant mutant strain bearing this mutation was not cross-resistant to the pederin family member mycalamide A, which binds to the archaeal form of the same protein. Thus, two pederin family members likely differ in how they bind the same molecular target. The accumulation of psymberin in cells was sensitive to the stereochemistry of the amide side chain at C4 or C8 and the presence of the dihydroisocoumarin side chain. The observation that psymberin diastereomers or dihydroisocoumarin-truncated analogs lose all cytotoxic activity while retaining the ability to inhibit protein translation in a cell-free in vitro assay can be explained in the context of these differential cell uptake issues. Finally, we also demonstrate that the blistering activity associated with pederin and other members of the family is not due to their protein synthesis inhibiting activity. Unlike pederin and mycalamide, psymberin does not display irritant or blistering activity. PMID:23088155

A forward genetic screen in Caenorhabditis elegans was conducted to identify the molecular target(s) of psymberin. Multiple independent psymberin-resistant mutants were isolated, each containing the same point mutation in a gene encoding a ribosomal protein. However, a psymberin-resistant mutant strain bearing this mutation was not cross-resistant to the pederin family member mycalamide A, which binds to the archaeal form of the same protein. Thus, two pederin family members likely differ in how they bind the same molecular target. The accumulation of psymberin in cells was sensitive to the stereochemistry of the amide side chain at C4 or C8 and the presence of the dihydroisocoumarin side chain. The observation that psymberin diastereomers or dihydroisocoumarin-truncated analogs lose all cytotoxic activity while retaining the ability to inhibit protein translation in a cell-free in vitro assay can be explained in the context of these differential cell uptake issues. Finally, we also demonstrate that the blistering activity associated with pederin and other members of the family is not due to their protein synthesis inhibiting activity. Unlike pederin and mycalamide, psymberin does not display irritant or blistering activity.

    Receiving information related to patients hospitalized in the intensive care unit is among the most important needs of the family members of such patients. When health care professionals should decide whether to be honest or to give hope, giving information becomes an ethical challenge We conducted a research to study the ethical approaches of Iranian nurses to giving information to the family members of patients in the intensive care units. This research was conducted in the intensive care units of three teaching hospitals in Iran. It employed a qualitative approach involving semi-structured and in-depth interviews with a purposive sample of 12 nurses to identify the ethical approaches to giving information to family members of the intensive care unit patients. A conventional content analysis of the data produced two categories and five subcategories. The two categories were as follows: a) informational support, and b) emotional support. Informational support had 2 subcategories consisting of being honest in giving information, and providing complete and understandable information. Emotional support in giving information had 3 sub-categories consisting of gradual revelation, empathy and assurance. Findings of the study indicated that ethical approaches to giving information can be in the form of either informational support or emotional support, based on patients' conditions and prognoses, their families' emotional state, the necessity of providing a calm atmosphere in the ICU and the hospital, and other patients and their families' peace. Findings of the present study can be used as a basis for further studies and for offering ethical guidelines in giving information to the families of patients hospitalized in the ICU.

    The 5th International Conference of the Institute for Patient- and Family-Centered Care (IPFCC), held in Washington, DC, from June 4-6, 2012, offered an opportunity for almost 1,000 conference participants to share and learn about exciting new patient- and family-centered initiatives occurring across the U.S. and in many other countries. One focus addressed by keynote and plenary speakers, as well as numerous conference sessions and poster presentations, was how nurses and other health care professionals can encourage patients and family members to become partners with their health care teams. Various presenters shared strategies ranging from initial approaches to acknowledging family members as part of the team and offering simple, non-threatening roles in care provision, to policies and approaches inviting increased participation in health care encounters, to higher level involvement in the care planning process, and to partnership roles extending beyond care of the individual child and family. A wealth of ideas can be implemented at various levels by individual nurses, units, and health care institutions.

    The drive towards patient involvement in health services has been increasingly promoted. The World Health Organisation emphasizes the family's perspective in comprehensive care. Internationally there is an increased emphasis on what patients and their family tell about the hospital experiences. However, current literature does not adequately address the question of participation experiences among relatives of older hospitalized family members. There is a paucity of research with a generational perspective on relatives' opportunities to exert influence. The aim of the study was to explore relatives' experiences of opportunities to participate in decisions about the care and treatment of older hospitalized family members and whether there are different experiences of influence to the relatives' age. This was an explorative study applying individual qualitative interviews. The interviews were analysed following hermeneutic methodological principles. Two Norwegian geriatric wards participated: one at a university hospital and one at a local hospital. Twelve participants, six women and six men, were purposively selected. The relatives were aged from 36 to 88 (mean age 62) and were spouses, children and/or children-in-law of patients. The relatives' experienced opportunities to exert influence were distributed along a continuum ranging from older relatives being reactive waiting for an initiative from health professionals, to younger adults being proactive securing influence. Older "invisible" carers appeared to go unnoticed by the health professionals, establishing few opportunities to influence decisions. The middle-aged relatives also experienced limited influence, but participated when the hospital needed it. However, limited participation seemed to have less impact on their lives than in the older relatives. Middle-aged relatives and younger adults identified strategies in which visibility was the key to increasing the odds of gaining participation. The exceptional

    Full Text Available Abstract Background Translation initiation in eukaryotes involves the recruitment of mRNA to the ribosome which is controlled by the translation factor eIF4E. eIF4E binds to the 5'-m7Gppp cap-structure of mRNA. Three dimensional structures of eIF4Es bound to cap-analogues resemble 'cupped-hands' in which the cap-structure is sandwiched between two conserved Trp residues (Trp-56 and Trp-102 of H. sapiens eIF4E. A third conserved Trp residue (Trp-166 of H. sapiens eIF4E recognizes the 7-methyl moiety of the cap-structure. Assessment of GenBank NR and dbEST databases reveals that many organisms encode a number of proteins with homology to eIF4E. Little is understood about the relationships of these structurally related proteins to each other. Results By combining sequence data deposited in the Genbank databases, we have identified sequences encoding 411 eIF4E-family members from 230 species. These sequences have been deposited into an internet-accessible database designed for sequence comparisons of eIF4E-family members. Most members can be grouped into one of three classes. Class I members carry Trp residues equivalent to Trp-43 and Trp-56 of H. sapiens eIF4E and appear to be present in all eukaryotes. Class II members, possess Trp→Tyr/Phe/Leu and Trp→Tyr/Phe substitutions relative to Trp-43 and Trp-56 of H. sapiens eIF4E, and can be identified in Metazoa, Viridiplantae, and Fungi. Class III members possess a Trp residue equivalent to Trp-43 of H. sapiens eIF4E but carry a Trp→Cys/Tyr substitution relative to Trp-56 of H. sapiens eIF4E, and can be identified in Coelomata and Cnidaria. Some eIF4E-family members from Protista show extension or compaction relative to prototypical eIF4E-family members.

    The Dandy-Walker syndrome (DWS) is a hereditary disorder, appearing somewhat more frequently in women. The most important characteristics of the DWS are the lack of the cerebellar vermis, varying from a partial lack to a complete agenesis, and enlargement of the cerebrospinal spaces, especially in the fourth ventricle. The above mentioned morphological changes clinically manifest in ataxia, increased intracranial pressure and hydrocephalus. Here is presented a family with DWS, where the disease is contracted only by female members, in two generations, whereas no signs of DWS have been noticed in male family members. DWS is clinically manifested from early childhood to middle age, with the morphological changes varying from hypoplastic cerebellar vermis to widening of the brain ventricles and hydrocephalus and arachnoid cyst in the occipital part.

    Full Text Available Introduction. Compassion fatigue is a concept used with increasing frequency in the nursing literature. The objective of this paper is to identify common themes across the literature and to apply these themes, and an existing model of compassion fatigue, to informal caregivers for family members with dementia. Findings. Caregivers for family members with dementia may be at risk for developing compassion fatigue. The model of compassion fatigue provides an informative framework for understanding compassion fatigue in the informal caregiver population. Limitations of the model when applied to this population were identified as traumatic memories and the emotional relationship between parent and child, suggesting areas for future research. Conclusions. Research is needed to better understand the impact of compassion fatigue on informal caregivers through qualitative interviews, to identify informal caregivers at risk for compassion fatigue, and to provide an empirical basis for developing nursing interventions for caregivers experiencing compassion fatigue.

    Full Text Available Delusional parasitosis (Ekbom syndrome is an uncommon psychiatric disorder that presents with a delusion of being infested with parasites. Treatment of this condition is difficult as patients with this paranoid disorder reject psychiatric diagnosis and treatment and often consult a dermatologist. Sharing the delusional beliefs of the paranoid patient by other people living in close emotional bonding with him/her could occur. We report here the clinically interesting phenomenon of delusion of parasitosis occurring simultaneously in all the members of a family. There was a pathological bonding between the members of the family who all presented to the dermatologist and rejected treatment. Dermatologists need to be aware of this uncommon clinical picture.

    2012-04-01

    The roles of amyloid precursor protein (APP) family members in normal brain function are poorly understood. Under physiological conditions the majority of APP appears to be processed along the non-amyloidogenic pathway leading to the formation of the secreted N-terminal APP fragment sAPPα. This cleavage product of APP has been implicated in several physiological processes such as neuroprotection, synaptic plasticity, neurite outgrowth and synaptogenesis. In this review we focus on the role of APP family members in neuroprotection and summarize the cellular and molecular mechanisms which are believed to mediate this effect. We propose that a reduction of APP processing along the non-amyloidogenic pathway during brain aging could result in an enhanced susceptibility of neurons to cellular stress and could contribute to neurodegeneration in Alzheimer's disease.

    By using the EST strategy for identifying novel members belonging to homologous gene families, a novel full-length cDNA encoding a protein significantly homologous to UDP-Gal: N-acetylglucosamine β-1, 4-galactosyltransferase (GAlT) was isolated from a human testis cDNA library. A nucleotide sequence of 2 173 bp long was determined to contain an open reading frame of 1032 nucleotides (344 amino acids). In view of the homology to members of the galactosyltransferase gene family and especially the closest relationship to Gallus gallus GalT type I (CK I), the predicted product of the novel cDNA was designated as human β-1, 4-galactosyltransferase homolog I (HumGT-H1). Its mRNA is present in different degrees in 16 tissues examined. Southern analysis of human genomic DNA revealed its locus on chromosome 3.

    The interleukin (IL)-1 family consists of 11 members, which all play significant roles in regulating inflammatory responses in the host. IL-1α and IL-1β exert potent pro-inflammatory effects and are key players in the recruitment of neutrophils to the site of inflammation. Protective anti-Aspergillus host responses during the early stages of invasive aspergillosis are critically dependent on neutrophil recruitment, and several lines of evidence support that there is an important role for IL-1 in this process. However, IL-1-mediated inflammation needs to be tightly regulated, since uncontrolled inflammation can result in inflammatory pathology and thereby be detrimental for the host. Aspergillus-induced IL-1-mediated inflammation could therefore be amendable for IL-1 blockade under specific circumstances. This review describes the current understanding of the role of IL-1 family members in the host response against Aspergillus fumigatus and highlights the importance of balanced IL-1 responses in aspergillosis.

    Several members of the family Luteoviridae are important pathogens of cultivated plant species of the family Gramineae. In this study, we explored RNA-silencing suppressors (RSSs) encoded by two cereal-infecting luteoviruses: barley yellow dwarf virus and wheat yellow dwarf virus (BYDV and WYDV, respectively). The P0 protein of WYDV-GPV (P0(GPV)) and the P6 protein of BYDV-GAV (P6(GAV)) displayed RSS activities when expressed in agro-infiltrated leaves of Nicotiana benthamiana, by their local ability to inhibit post-transcriptional gene silencing of GFP. Analysis of GFP, mRNA and GFP-specific small interfering RNA indicated that both P0(GPV) and P6(GAV) are suppressors of silencing that can restrain not only local but also systemic gene silencing. This is the first report of RSS activity of the P6 protein in a member of the genus Luteovirus.

    The six members of the E2F family of transcription factors play a key role in the control of cell cycle progression by regulating the expression of genes involved in DNA replication and cell proliferation. E2F-1, -2, and -3 belong to a structural and functional subfamily distinct from those...... of the other E2F family members. Here we report that E2F-1, -2, and -3, but not E2F-4, -5, and -6, associate with and are acetylated by p300 and cAMP-response element-binding protein acetyltransferases. Acetylation occurs at three conserved lysine residues located at the N-terminal boundary of their DNA...

  10. Importance of dimer formation of myocardin family members in the regulation of their nuclear export.

    2013-01-01

    Myocardin (Mycd) family members function as a transcriptional cofactor for serum response factor (SRF). Dimer formation is necessary to exhibit their function, and the coiled-coil domain (CC) plays a critical role in their dimerization. We have recently revealed a detailed molecular mechanism for their Crm1 (exportin1)-mediated nuclear export. Here, we found other unique significances of the dimerization of Mycd family members. Introduction of mutations in the CC of myocardin-related transcription factor A (MRTF-A) and truncated Mycd resulted in significant decreases in their cytoplasmic localization and increases in their nuclear localization. In accordance with such subcellular localization changes, their binding to Crm1 were reduced. These results indicate that the dimerization of Mycd family members is necessary for their Crm1-mediated nuclear export. We have recently found that the N-terminal region of Mycd consisting of 128 amino acids (Mycd N128) self-associates to Mycd via the central basic domain (CB), resulting in masking the Crm1-binding site. Such self-association of MRTF-A would be unlikely. In this study, we also revealed that the dimerization of Mycd was also necessary for this self-association. Wild-type Mycd activated SRF-mediated transcription more potently than Mycd lacking the Mycd N128 (Mycd ΔN128) did. These results suggest two possible functions of the Mycd N128: 1) stabilization of Mycd dimer to enhance SRF-mediated transcription and 2) positive regulation of the transactivation ability of Mycd. These findings provide a new insight into the functional regulation of Mycd family members.

    Peroxisome proliferators-activated receptor (PPAR) gene family members exhibit distinct patterns of distribution in tissues and differ in functions. The purpose of this study is to investigate the evolutionary impacts on diversity functions of PPAR members and the regulatory differences on gene expression patterns. 63 homology sequences of PPAR genes from 31 species were collected and analyzed. The results showed that three isolated types of PPAR gene family may emerge from twice times of gene duplication events. The conserved domains of HOLI (ligand binding domain of hormone receptors) domain and ZnF_C4 (C4 zinc finger in nuclear in hormone receptors) are essential for keeping basic roles of PPAR gene family, and the variant domains of LCRs may be responsible for their divergence in functions. The positive selection sites in HOLI domain are benefit for PPARs to evolve towards diversity functions. The evolutionary variants in the promoter regions and 3' UTR regions of PPARs result into differential transcription factors and miRNAs involved in regulating PPAR members, which may eventually affect their expressions and tissues distributions. These results indicate that gene duplication event, selection pressure on HOLI domain, and the variants on promoter and 3' UTR are essential for PPARs evolution and diversity functions acquired.

    Full Text Available Abstract Background Family members of patients with end stage renal disease were reported to have an increased prevalence of chronic kidney disease (CKD. However, studies differentiated genetic and non-genetic family members are limited. We sought to investigate the prevalence of CKD among fist-degree relatives and spouses of dialysis patients in China. Methods Seventeen dialysis facilities from 4 cities of China including 1062 first-degree relatives and 450 spouses of dialysis patients were enrolled. Sex- and age- matched controls were randomly selected from a representative sample of general population in Beijing. CKD was defined as decreased estimated glomerular (eGFR 2 or albuminuria. Results The prevalence of eGFR less than 60 mL/min/1.73 m2, albuminuria and the overall prevalence of CKD in dialysis spouses were compared with their counterpart controls, which was 3.8% vs. 7.8% (P 2, albuminuria and the overall prevalence of CKD in dialysis relatives were also compared with their counterpart controls, which was 1.5% vs. 2.4% (P = 0.12, 14.4% vs. 8.4% (P  Conclusions The association between being family members of dialysis patients and presence of CKD is different between first-degree relatives and spouses.

    Many prior nursing studies regarding family members specifically of neuroscience intensive care unit (neuro-ICU) patients have focused on identifying their primary needs. A concept related to identifying these needs and assessing whether they have been met is determining whether families explicitly report satisfaction with the care that both they and their loved ones have received. The objective of this study was to explore family satisfaction with care in an academic neuro-ICU and compare results with concurrent data from the same hospital's medical ICU (MICU). Over 38 days, we administered the Family Satisfaction-ICU instrument to neuro-ICU and MICU patients' families at the time of ICU discharge. Those whose loved ones passed away during ICU admission were excluded. When asked about the respect and compassion that they received from staff, 76.3% (95% CI [66.5, 86.1]) of neuro-ICU families were completely satisfied, as opposed to 92.7% in the MICU (95% CI [84.4, 101.0], p = .04). Respondents were less likely to be completely satisfied with the courtesy of staff if they reported participation in zero formal family meeting. Less than 60% of neuro-ICU families were completely satisfied by (1) frequency of physician communication, (2) inclusion and (3) support during decision making, and (4) control over the care of their loved ones. Parents of patients were more likely than other relatives to feel very included and supported in the decision-making process. Future studies may focus on evaluating strategies for neuro-ICU nurses and physicians to provide better decision-making support and to implement more frequent family meetings even for those patients who may not seem medically or socially complicated to the team. Determining satisfaction with care for those families whose loved ones passed away during their neuro-ICU admission is another potential avenue for future investigation.

    Substantial progress has been made in identifying genes that raise risk for epilepsy, and genetic testing for some of these genes is increasingly being used in clinical practice. However, almost no empirical data are available from the perspective of people with epilepsy and their family members about the impact of genetic information and potential benefits and harms of genetic testing. To address this gap we conducted in-depth qualitative interviews with 40 individuals (22 with epilepsy, 18 unaffected) in the USA from families containing multiple affected individuals who had participated in epilepsy genetics research. The interviews were coded and analyzed using the principles of grounded theory. Several major themes emerged from these interviews. Participants expressed "personal theories of inheritance" that emphasized commonalities among relatives and the idea that disease risk is most shared by family members who share physical or personality traits. Most participants said they would have genetic testing if it were offered. They cited many potential benefits, including learning what caused epilepsy in their family, being better able to care and advocate for children at risk, reducing guilt and blame, providing an increased sense of control, and relieving anxiety in unaffected individuals who test negative. The influence of genetic information on reproduction was a particularly salient theme. Although respondents believed genetic testing would be useful for informing their reproductive choices, they also expressed fear that it could lead to external pressures to modify these choices. Other concerns about the potential negative impact of genetic information included increased blame and guilt, increased stigma and discrimination in employment and insurance, self-imposed limitations on life goals, and alterations in fundamental conceptions of "what epilepsy is." Consideration of the perspectives of people with epilepsy and their family members is critical to

    Even though more than 25% of Americans die in nursing homes, end-of-life care has consistently been found to be less than adequate in this setting. Even for those residents on hospice, end-of-life care has been found to be problematic. This study had 2 research questions; (1) How do family members of hospice nursing home residents differ in their anxiety, depression, quality of life, social networks, perceptions of pain medication, and health compared with family members of community dwelling hospice patients? (2) What are family members' perceptions of and experiences with end-of-life care in the nursing home setting? This study is a secondary mixed methods analysis of interviews with family members of hospice nursing home residents and a comparative statistical analysis of standard outcome measures between family members of hospice patients in the nursing home and family members of hospice patients residing in the community. Outcome measures for family members of nursing home residents were compared (n = 176) with family members of community-dwelling hospice patients (n = 267). The family members of nursing home residents reported higher quality of life; however, levels of anxiety, depression, perceptions of pain medicine, and health were similar for hospice family members in the nursing home and in the community. Lending an understanding to the stress for hospice family members of nursing home residents, concerns were found with collaboration between the nursing home and the hospice, nursing home care that did not meet family expectations, communication problems, and resident care concerns including pain management. Some family members reported positive end-of-life care experiences in the nursing home setting. These interviews identify a multitude of barriers to quality end-of-life care in the nursing home setting, and demonstrate that support for family members is an essential part of quality end-of-life care for residents. This study suggests that nursing

    Full Text Available Melamine is a new risk of urinary stones. Gansu province is a heavily affected area and has large population and underdeveloped economy. We hypothesized that number of family members and family income may play significant roles in the formation of urinary stones. A case-control study was performed among 190 infants. Results showed that the case group had less numbers of family members than the control (4.4 vs. 5.6, respectively. The multivariate logistic regression analysis indicated that number of family members was an independent influencing factor associated with urinary stones (OR, 0.606; 95% CI, 0.411-0.893; P = 0.011. Family income, however, did not exhibit a significant difference. Observed results suggested that number of family members was a new and significant influencing factor to affect the risk of melamine-associated urinary stones.

    To examine the experiences of caregiving among Vietnamese family members of persons living with HIV/AIDS. As the number of persons living with HIV/AIDS increases, the need of family caregivers who can take responsibility for the home care of these persons increases. Vietnam has one of the fastest growing HIV epidemics in Asia. A descriptive cross-sectional study with quantitative and qualitative methods was used. A purposive sample of 104 family caregivers, both male and female, participated voluntarily by answering a questionnaire of caregiver burden, and 20 of them participated in in-depth interview. Female caregivers were mainly mothers and wives while male caregivers were mainly husbands, fathers and siblings. The largest group of family caregivers reported moderate to severe burden. There was no difference between genders in total caregiver burden, but there were several differences between older and younger caregivers in some items of caregiver burden. Five categories of experiences emerged: Different types of caregiving to persons living with HIV/AIDS, cultural and religious issues associated with caregiving, keeping secret to avoid stigma and discrimination, lack of knowledge about disease and provision of care, and fear, anxiety and frustration. Stigma and discrimination should be decreased by providing knowledge to the general public about HIV/AIDS, in particular about ways of transmission and protection. Special knowledge should be given to family caregivers to enable them to give care to persons living with HIV/AIDS at home. This could be done through culturally appropriate training/intervention programmes in which coping methods should be included. Support group interventions should also be carried through. The results obtained can be used as baseline information. Health care providers should consider gender, age and culture of family members of persons living with HIV/AIDS. Knowledge about HIV/AIDS, provision of care at home and in hospital, and

    The amyloid precursor protein (APP) as well as its homologues, APP-like protein 1 and 2 (APLP1 and APLP2), are cleaved by α-, β-, and γ-secretases, resulting in the release of their intracellular domains (ICDs). We have shown that the APP intracellular domain (AICD) is transported to the nucleus by Fe65 where they jointly bind the histone acetyltransferase Tip60 and localize to spherical nuclear complexes (AFT complexes), which are thought to be sites of transcription. We have now analyzed the subcellular localization and turnover of the APP family members. Similarly to AICD, the ICD of APLP2 localizes to spherical nuclear complexes together with Fe65 and Tip60. In contrast, the ICD of APLP1, despite binding to Fe65, does not translocate to the nucleus. In addition, APLP1 predominantly localizes to the plasma membrane, whereas APP and APLP2 are detected in vesicular structures. APLP1 also demonstrates a much slower turnover of the full-length protein compared to APP and APLP2. We further show that the ICDs of all APP family members are degraded by the proteasome and that the N-terminal amino acids of ICDs determine ICD degradation rate. Together, our results suggest that different nuclear signaling capabilities of APP family members are due to different rates of full-length protein processing and ICD proteasomal degradation. Our results provide evidence in support of a common nuclear signaling function for APP and APLP2 that is absent in APLP1, but suggest that APLP1 has a regulatory role in the nuclear translocation of APP family ICDs due to the sequestration of Fe65.

Estudo qualitativo com dados coletados a partir de entrevistas semiestruturadas e observação com 16 familiares acompanhantes de pessoas hospitalizadas com dependência para o autocuidado. Os dados foram submetidos à análise temática e analisados através da metáfora da tribo proposta pela sociologia compreensiva. Os familiares formam um agrupamento social em torno do cuidado onde encontramos as características das tribos: a ambiência emocional; a solidariedade baseada nos vínculos de simpatia e ajuda mútua; a nebulosa afetual no processo interacional; a lógica da fusão nas relações tácteis e a comunhão/religiosidade no processo de ligação numa identidade coletiva. Os familiares na presença do trágico criam agrupamentos sociais que se assemelham a tribos cujo totem é o cuidado. Understand the quotidian relationships of accompanying family members in an environment of care, which are close to the metaphor of a tribe in hospital environment. METHODQualitative study with data gathered from semi-structured interviews and observations with 16 family members accompanying hospitalized individuals with dependence on self-care. Data were submitted to thematic analysis, and analyzed through the metaphor of "tribe" proposed by comprehensive sociology. Family members build up social clusters around caring, where we find traits typical of tribes: emotional ambience; solidarity based on links of sympathy and mutual assistance; an affectual nebula in the process of interaction; a logic of fusion in tactile relations; and communion/religiosity in the process of connecting in a collective identity. In the presence of tragedy, families build social clusters similar to tribes having care as a totem.

    Full Text Available Background: smoking is a very important public health problem, urgently requiring immediate and effective measures due to its harmful effect on health. The purpose of this study was to collect baseline information about the magnitude of smoking problem, knowledge, attitude, and practice among family members of primary school students in the northwest region of Iran.Methods: of 55 680 primary school students (the 3th, 4th and 5th grades, 7.1% (n=3 954 were selected using randomized multi-stage cluster sampling. Data collection was conducted in April, May, and June 2011, by means of a self-administered two-page questionnaire.Results: a total of 3 954 students (57.6% boys and 42.3% girls with the mean age of 10.46±1.09 years were evaluated. According to our data, the prevalence of cigarette smoking among fathers was more than other family members (27.1% versus 17.8% whereas the prevalence of water pipe smoking among fathers and other family members was almost similar (9.2% and 9.7% respectively. None of the smoking type was prevalent among mothers (cigarette: 1% and water pipe: 1.1%. Considerable numbers of all students under study had been exposed to secondhand smoke at home (cigarette: 19.8% and water pipe: 7.7%.Conclusions: considering our findings, two procedures recommended to prevail the problem are to provide greater education about hazards of tobacco consumption among students and their family; and to legislate new laws by officials to ban tobacco use at home.

    Trainees and practicing physicians alike find breaking bad, sad, or difficult news to a patient or family member as one of the most challenging communication tasks they perform. Interpersonal and communication skills are a core competency for resident training. However, in disciplines where technical skills have a major emphasis, such as surgery, the teaching of communication skills may not be a priority. The objective of our study is to review literature in order to identify best practices and learning modalities used to teach surgery trainees the communication skills regarding delivery of difficult news to patients and family members. The criteria for inclusion in this literature review were that the study (1) addresses surgeons' training (nontechnical skills) in breaking difficult news to patient and/or families, (2) describes a teaching modality or intervention targeted to teach surgery residents how to deliver difficult news to patient/family, and (3) is published in English. Articles (n = 225) were screened for final eligibility. After discarding duplicates and noneligible studies, and after abstract/full-text review, 18 articles were included in the final analysis. Most studies are single site; address general surgery residents at varying training levels; and include case-specific, outpatient, and intensive care unit (ICU) settings. There is a paucity of studies in the trauma and unexpected death setting. There is a recent trend to use Objective Structured Clinical Examination (OSCE) both to teach and assess communication skills. Variable tools are used to assess this competency as described. Simulation and OSCE format have emerged as modalities of choice both to teach surgery residents how to deliver difficult news and to assess achievement of this competency. There is a gap in the literature regarding teaching and assessing surgery resident communication skills in delivering difficult news after unexpected events in the trauma and operating room

    AIM: To determine the prevalence of hepatitis B in Nahavand and evaluate the HBsAg positive prevalence in families with a member who was confirmed to have HBV infection.METHODS: This study was performed in two phases. In the first phase, 1 824 subjects in Nahavand city were selected. The interviewers visited the houses of chosen families to fill the questionnaire and take the blood samples.All subjects signed an informed consent before interviews and blood sampling. The samples were evaluated for HBV virologic markers. In the second phase, 115 HBsAg-positive cases were enrolled and evaluated for HBV virologic markers.RESULTS: The prevalence of positive HBsAg in Nahavand was 2.3%. The most frequent relatives of index cases were sons and daughters (32.2% and 23.5% respectively).Twelve (11%) of all family members were HBsAg positive.Fifty (56.2%) were isolated HBsAb positive and only one person (2.5%) was isolated HBcAb positive. The higher rates of HBsAg marker were detected in the brothers (1-25%) and fathers (1-12.5%). The infection rate in husbands and wives of index cases was 10%. Only two (16.7%) of all HBsAg-positive participants reported previous HBV vaccination.CONCLUSION: The prevalence of intra-familial HBV infection is lower in Nahavand of Iran compared to other studies.More attention should be paid to HBV vaccination and risk-lowering activities.

    Since the official launching of the Philippine Population Program in 1970, family planning campaigns have substantially addressed themselves to women. The suggestion to devote equal, if not more, attention to men as family planning targets had been raised by Dr. Mercado as early as 1971. It was not until 1978, that the deliberate inclusion of males as a target audience in family planning became a matter of policy. The Population Center Foundation (PCF), from 1979 to 1982, carried out research projects to determine the most suitable approaches and strategies to reach Filipino men. The objectives of the PCF's Male Specific Program are: 1) to test alternative schemes in promoting male family planning methods through pilot-testing of family planning clinics for men, 2) to develop teaching materials geared toward specific segments of the male population, 3) to undertake skills training in male-specific motivational approaches for program professionals, and 4) to assess the extent of the husband's role in family planning. An important finding of 1 study was that most outreach workers were female stood in the way of the motivation process, thus hampering the campaign. While the consultative motivational skills training improved knowledge, attitudes, and skills of outreach workers with regard to vasectomy and the motivation process, there were certain predispositions that were hindering the fieldworkers' effectiveness in motivating target clients. Overall, in-depth, 1-to-1 motivation in dealing with men is needed to strengthen internalization of family planning values.

    A sense of imbalance is common among both professors and therapists, though few studies have been published examining the work and personal life balance of those who work in both professions simultaneously. Using in-depth telephone interviews, this study examined the work and personal life balance of 16 marriage and family therapy (MFT) faculty members. Results showed that six were satisfied with their balance, six were dissatisfied, and four were "middle of the road." Men, older participants, and those who were in their career longer were more likely to report feeling satisfied with their balance. Internal indicators of their balance included family and workplace messages, health indicators, feelings of contentment, and congruence with personal values. Child and relationship status, tenure status, and gender issues also impacted their sense of balance. Specific balance enhancers and reducers were highlighted, and participants discussed coping strategies and recommendations for other MFT faculty members. Clinical, training, and career implications are discussed. © 2010 American Association for Marriage and Family Therapy.

    Excessive alcohol use has been associated with health, social and legal problems. Alcohol-related problems have been studied primarily in problem-drinker patients, with few studies on their family members, particularly about their own hazardous or harmful alcohol-drinking behaviours. In this qualitative descriptive study, participants were recruited from three hospitals randomly selected from northern and central Taiwan (2:1). Hazardous-drinker patients and their family members were screened using the Chinese version Alcohol Use Disorders Identification Test (scores ≥8 indicate harmful or hazardous drinkers). Data were collected in individual, audiotaped, in-depth interviews using an interview guide. Verbatim interview transcripts were analysed using ATLAS.ti, version WIN 7.0. The sample of 35 family members with hazardous or harmful drinking behaviours perceived that their own alcohol-drinking behaviours were related to six major patterns: family habits, leisure activities with friends, work pressures, personal taste, a way to forget one's problems and to express happiness. We recommend that programmes targeting harmful or hazardous drinking among problem-drinker patients' family members should educate participants about the standard amounts of alcohol in alcoholic beverages, recommended amounts of alcohol consumption for males and females, the long-term effects of excessive alcohol consumption; address sources of risk factors at work; offer strategies to resist social pressures to drink; and build positive strategies for coping with stress.

    There is almost no data on the role of social support and in general on posttraumatic growth among people who have missing family member(s) as result of war and who experience ambiguous loss. This study explores relationship between reported posttraumatic growth and perceived social support and social activism in community-based organizations dealing directly with issues of missing persons. Family members who reported higher levels of social support from family, friends, and important others reported significant higher levels of posttraumatic growth. Family members that reported being active in community-based organizations reported significant higher averages in posttraumatic growth scores in total and its subscales. Regression analyses indicates that factors associated posttraumatic growth were as follows: being active in community organization dealing with missing person's issues and higher levels of social support from friends and family. Findings provide insight for clinicians working with this population and psycho social experts working in postconflict contexts.

    The role of incarceration and community reentry after incarceration has been studied extensively for individual and community health; however, little attention has been given to the experiences of individuals who provide support to those in reentry. Through a community-academic partnership, seven focus groups were conducted with 39 individuals supporting a family member in reentry in the summer of 2012. The primary objectives of the focus groups were to explore community experiences and perspectives regarding providing support during a family member's reentry from a period of incarceration and any desired support for themselves during this time. Five themes emerged under a metatheme of stress, indicating that family members experience acute stress as a result of family reentry that adds to the chronic stress they already endure. Programs that acknowledge the difficult role of family members as supporters during an individual's reentry and provide support to them are desperately needed.

    Mutation (substitution, deletion, insertion, etc.) in nucleotide acid causes the maximal sequence lengths of exact match (MALE) between paralogous members from a duplicate event to become shorter during evolution. In this work, MALE changes between members of 26 gene families from four representative species (Arabidopsis thaliana, Oryza sativa, Mus musculus and Homo sapiens) were investigated. Comparative study ofparalogous' MALE and amino acid substitution rate (dA<0.5)indicated that a close relationship existed between them. The results suggested that MALE could be a sound evolutionary scale for the divergent time for paralogous genes during their early evolution. A reference table between MALE and divergent time for the four species was set up, which would be useful widely, for large-scale genome alignment and comparison. As an example, detection of large-scale duplication events of rice genome based on the table was illustrated.

    The aim of this study was to develop a model of mental health professional (MHP) support based on the needs of families with a member suffering from severe mental illness (SMI). Twelve family members were interviewed with the focus on their needs of support by MHP, then the interviews were analyzed according to the grounded theory method. The generated model of MHP support had two core categories: the family members' process from crisis to recovery and their interaction with the MHP about mental health/illness and daily living of the person with SMI. Interaction based on ongoing contact between MHP and family members influenced the family members' process from crisis towards recovery. Four MHP strategies--being present, listening, sharing and empowering--met the family members' needs of support in the different stages of the crisis. Being present includes early contact, early information and protection by MHP at onset of illness or relapse. Listening includes assessing burden, maintaining contact and confirmation in daily living for the person with SMI. Sharing between MHP and family members includes co-ordination, open communication and security in daily living for the person with SMI. Finally, the MHP strategy empowering includes creating a context, counselling and encouraging development for the family members. The present model has a holistic approach and can be used as an overall guide for MHP support in clinical care of families of persons with SMI. For future studies, it is important to study the interaction of the family with SMI and the connection between hope, coping and empowerment.

  3. Nuclear import mechanism for myocardin family members and their correlation with vascular smooth muscle cell phenotype.

    Myocardin (Mycd), which is essential for the differentiation of the smooth muscle cell lineage, is constitutively located in the nucleus, although its family members, myocardin-related transcription factors A and B (MRTF-A/B), mostly reside in the cytoplasm and translocate to the nucleus in response to Rho signaling. The mechanism for their nuclear import is unclear. Here we investigated the mechanism for the nuclear import of Mycd family members and demonstrated any correlation between such mechanism and the phenotype of vascular smooth muscle cells (VSMCs). In cultured VSMCs, the knockdown of importin β1 inhibited the nuclear import of Mycd and MRTF-A/B. Their NH(2)-terminal basic domain was identified as a binding site for importin α/β1 by in vitro analyses. However, Mycd had a higher affinity for importin α/β1 than did MRTF-A/B, even in the absence of G-actin, and Mycd affinity for importin α1/β1 was stronger than for any other importin α/β1 heterodimers. The binding of Mycd to importin α/β1 was insensitive to G-actin, whereas that of MRTF-A/B was differently inhibited by G-actin. In dedifferentiated VSMCs, the levels of importins α1 and β1 were reduced concomitant with down-regulation of Mycd, serum response factor, and smooth muscle cell markers. By contrast, in differentiated VSMCs, their expressions were up-regulated. Thus, the nuclear import of Mycd family members in VSMCs depends on importin α/β1, and their relative affinities for importin α/β1 heterodimers determine Mycd nuclear import. The expression of Mycd nuclear import machineries is related to the expression levels of VSMC phenotype-dependent smooth muscle cell markers.

    The degree and quality of resilience in patients with depression have never been investigated in the context of remission status, spirituality/religiosity, and family members' resilience levels, which was addressed in this study. This cross-sectional study recruited Japanese outpatients with depressive disorder according to ICD-10 and cohabitant family members who were free from psychiatric diagnoses. Resilience was assessed using the 25-item Resilience Scale (RS). Other assessments included the Montgomery-Asberg Depression Rating Scale (MADRS); the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being Scale (FACIT) and Kasen et al.'s (2012) scale for spirituality/religiosity; and the Rosenberg Self-Esteem Scale (RSES). One hundred outpatients with depression (mean±SD age, 50.8±14.5years; 44 men; MADRS total score 9.8±9.0) and 36 healthy family members (mean±SD age, 56.5±15.0years; 18 men) were included. Symptom severity, attendance at religious/spiritual services, and self-esteem were significantly associated with RS scores in the patient group. RS total scores were significantly higher in remitted patients compared to non-remitted patients (mean±SD, 112.3±17.1 vs. 84.8±27.7, pself-esteem or spirituality/religiosity may represent reinforcing elements. While caution is necessary in extrapolating these findings to other patient populations, our results suggest that resilience may be considered a state marker in depression.

    Regulators of G protein signaling (RGS) proteins bind to active G alpha subunits and accelerate the rate of GTP hydrolysis and/or block interaction with effector molecules, thereby decreasing signal duration and strength. RGS proteins are defined by the presence of a conserved 120-residue region termed the RGS domain. Recently, it was shown that the G protein-coupled receptor kinase 2 (GRK2) contains an RGS domain that binds to the active form of G alpha(q). Here, the ability of GRK2 to interact with other members of the G alpha(q) family, G alpha(11), G alpha(14), and G alpha(16), was tested. The signaling of all members of the G alpha(q) family, with the exception of G alpha(16), was inhibited by GRK2. Immunoprecipitation of full-length GRK2 or pull down of GST-GRK2-(45-178) resulted in the detection of G alpha(q), but not G alpha(16), in an activation-dependent manner. Moreover, activated G alpha(16) failed to promote plasma membrane (PM) recruitment of a GRK2-(45-178)-GFP fusion protein. Assays with chimeric G alpha(q)(-)(16) subunits indicated that the C-terminus of G alpha(q) mediates binding to GRK2. Despite showing no interaction with GRK2, G alpha(16) does interact with RGS2, in both inositol phosphate and PM recruitment assays. Thus, GRK2 is the first identified RGS protein that discriminates between members of the G alpha(q) family, while another RGS protein, RGS2, binds to both G alpha(q) and G alpha(16).

    Full Text Available Abstract Background The E2F family of transcription factors is required for the activation or repression of differentially expressed gene programs during the cell cycle in normal and abnormal development of tissues. We previously determined that members of the retinoblastoma protein family that interacts with the E2F family are differentially expressed and localized in almost all the different cell types and tissues of the testis and in response to known endocrine disruptors. In this study, the cell-specific and stage-specific expression of members of the E2F proteins has been elucidated. Methods We used immunohistochemical (IHC analysis of tissue sections and Western blot analysis of proteins, from whole testis and microdissected stages of seminiferous tubules to study the differential expression of the E2F proteins. Results For most of the five E2F family members studied, the localizations appear conserved in the two most commonly studied rodent models, mice and rats, with some notable differences. Comparisons between wild type and E2F-1 knockout mice revealed that the level of E2F-1 protein is stage-specific and most abundant in leptotene to early pachytene spermatocytes of stages IX to XI of mouse while strong staining of E2F-1 in some cells close to the basal lamina of rat tubules suggest that it may also be expressed in undifferentiated spermatogonia. The age-dependent development of a Sertoli-cell-only phenotype in seminiferous tubules of E2F-1 knockout males corroborates this, and indicates that E2F-1 is required for spermatogonial stem cell renewal. Interestingly, E2F-3 appears in both terminally differentiated Sertoli cells, as well as spermatogonial cells in the differentiative pathway, while the remaining member of the activating E2Fs, E2F-2 is most concentrated in spermatocytes of mid to late prophase of meiosis. Comparisons between wildtype and E2F-4 knockout mice demonstrated that the level of E2F-4 protein displays a distinct

    We report the cloning and transient expression in HeLa cells of the five members of the human steroid 5α-reductase family as both N- and C-terminus green fluorescent protein tagged protein constructs. Following the intrinsic fluorescence of the tag, we have determined that the subcellular localization of these enzymes is in the endoplasmic reticulum, upon expression in HeLa cells. The presence of the tag at either end of the polypeptide chain can affect protein expression and, in the case of trans enoyl-CoA reductase, it induces the formation of protein aggregates.

    A receptor for the adhesive basement membrane protein, laminin, was isolated from human glioblastoma cells by affinity chromatography on laminin. This receptor has a heterodimeric structure similar to that of receptors for other extracellular matrix proteins such as fibronectin and vitronectin. Incorporation of the laminin receptor into liposomal membranes makes it possible for liposomes to attach to surfaces coated with laminin. The receptor liposomes also attached to some extent to surfaces coated with fibronectin, but not with other matrix proteins. These properties identify the laminin receptor as a member of the integrin family of cell adhesion receptors.

    Patients with active lymphoproliferative diseases (LPD) were shown to have high activity of lymphocyte uroporphyrinogen synthase (L-UROS), the enzyme which converts porphobilinogen to uroporphyrinogen. The mean L-UROS activity of 64 first-degree relatives of patients with LPD was significantly higher than that of a control group and 45% of these relatives had pathological values of L-UROS. L-UROS activity was also determined in the spouses of 2 patients and was pathologically elevated in both. The pattern of pathological values among family members may indicate the presence of a communicable agent.

    GAGE cancer/testis antigens are frequently expressed in many different types of cancer, whereas their expression in normal tissues is limited to the germ cells of the immune-privileged organs, testis and ovary. Thus, GAGE proteins may be attractive candidates for immunotherapy of cancer....... This review describes the structure and phylogeny of the GAGE family members and presents a revised nomenclature, which will enable a more clear distinction of genes and gene products. The GAGE gene locus at chromosome X p11.23 consists of at least 16 genes, each of which is located in one of an equal number...... cell biology. When expressed in tumor cells, GAGE proteins can elicit both cellular and humoral immune responses, indicating that they are appropriate targets for cancer immunotherapy. The potential use of GAGE proteins in cancer immunotherapy, including possible limitations, is also discussed....

    The fibroblast growth factors are a family of polypeptide growth factors involved in a variety of activities including mitogenesis, angiogenesis, and wound healing. Fibroblast growth factor receptors (FGFRs) have previously been identified in chicken, mouse, and human and have been shown to contain an extracellular domain with either two or three immunoglobulin-like domains, a transmembrane domain, and a cytoplasmic tyrosine kinase domain. The authors have isolated a human cDNA for another tyrosine kinase receptor that is highly homologous to the previously described FGFR. Expression of this receptor cDNA in COS cells directs the expression of a 125-kDa glycoprotein. They demonstrate that this cDNA encodes a biologically active receptor by showing that human acidic and basic fibroblast growth factors activate this receptor as measured by {sup 45}Ca{sup 2+} efflux assays. These data establish the existence of an additional member of the FGFR family that they have named FGFR-3.

    Anticipatory grief is the process associated with grieving the loss of loved ones in advance of their inevitable death. Because anticipatory grief has been associated with a variety of outcomes, risk factors for this condition deserve closer consideration. Fifty-seven family members of terminally ill, hospice-eligible veterans receiving palliative care services completed measures assessing psychosocial factors and conditions. Elevated anticipatory grief was found in families characterized by relational dependency, lower education, and poor grief-specific support, who also experienced discomfort with closeness and intimacy, neuroticism, spiritual crisis, and an inability to make sense of the loss. Thus, in this sample, anticipatory grief appears to be part of a cluster of factors and associated distress that call for early monitoring and possible intervention.

    The authors investigated posttraumatic stress disorder (PTSD) symptoms in Japanese bereaved family members using a questionnaire. Participants were bereaved as a result of suicide and homicide (n = 51 and 49, respectively), with natural death (n = 56) as a control; and their relationships to the deceased were parent-child (n = 79), conjugal (n = 42), and others (n = 35). With regard to the 3 main PTSD-related criteria, (a) re-experiencing symptoms were not dependent on the manner of death or the relationship to the deceased; (b) avoidance behaviors were more highly related to homicide than natural death for relatives other than parent-child and conjugal relationships; and (c) hyperarousal and maladaptation symptoms were more serious for conjugal loss. These findings suggest that avoidance behaviors in homicidal cases are more closely associated with a distant family relationship, whereas conjugal loss is traumatic, irrespective of the manner of death, often causing hyperarousal and maladaptation symptoms.

  14. A new Apicomplexa-specific protein kinase family : multiple members in Plasmodium falciparum, all with an export signature

    Full Text Available Abstract Background Malaria caused by protozoan parasites of the genus Plasmodium spp. is a major health burden in tropical countries. The development of new control tools, including vaccines and drugs, is urgently needed. The availability of genome sequences from several malaria parasite species provides a basis on which to identify new potential intervention targets. Database mining for orthologs to the Plasmodium falciparum trophozoite protein R45, a vaccine candidate, led us identify a new gene family. Results Orthologs to the P. falciparum trophozoite protein R45 were detected exclusively in protozoan parasites of the phylum Apicomplexa, including several Plasmodium spp., Toxoplasma gondii and Cryptosporidium parvum. All family members are hybrid genes with a conserved C-terminal protein kinase domain of a novel type, recently called FIKK kinase, associated with a non conserved N-terminal region without any known functional signature. While a single copy gene was detected in most species, considerable gene expansion was observed in P. falciparum and its closest phylogenic relative P. reichenowi, with 20 and six copies, respectively, each with a distinct N-terminal domain. Based on full length protein sequence, pairs of orthologs were observed in closely related species, such as P. berghei and P.y. yoelii, P. vivax and P. knowlesi, or P. reichenowi and P. falciparum. All 20 P. falciparum paralogs possess a canonical Plasmodium export element downstream of a signal / anchor sequence required for exportation outside the parasitophorous vacuole. This is consistent with the reported association of the trophozoite protein R45, the only paralog characterised to date, with the infected red blood cell membrane. Interestingly, most genes are located in the subtelomeric region of chromosomes, in association with other multigene families contributing to the remodelling of the infected red blood cell membrane, in particular the ring erythrocyte surface

    To explore potential differences within dyads of patients' with lung cancer and family members' judgment of different aspects of quality of care and relationships between quality of care and personal and health-related characteristics. High quality of care is important for acceptable quality of life in patients in palliative care. If patients are unable to participate in quality of care assessments or decision-making, family members might often act as proxies, despite the complicated nature of their own situation. Cross-sectional survey design. A patient and family member version of the abbreviated questionnaire Quality from Patients' Perspective, with additional items about perceived health and opinions about care, was mailed to members of the Swedish lung cancer Patient Organisation. Wilcoxon's signed rank test was used to identify potential differences within 51 patient-family member dyads' quality of care ratings. Relationships between Quality from Patients' Perspective dimensions and demographic and health-related variables were examined with Spearman's correlations. Patient-family member dyads had high levels of agreement in ratings of perceived reality of quality of care. Family members generally rated the subjective importance of individual items higher than did the patient in the dyad, with significant difference in the dimension 'socio-cultural approach'. Older patients were found to rate the physical-technical conditions higher than younger patients, in relation to perceived reality but not subjective importance. Women family members were found to rate the subjective importance of medical-technical competence, identity-oriented approach and socio-cultural approach significantly higher than men did. Patients with lung cancer and their family members agree in ratings of the perceived reality, but they differ more in ratings of the subjective importance of quality of care. When patients are unable to communicate their preferences, family members' opinions

Based on the continuing need for new therapeutics to treat bunyavirus infections, we evaluated the potential efficacy of FGI-106, a small-molecular compound that previously demonstrated activity against different RNA viruses. FGI-106 displayed substantial antiviral activity in cell-based assays of different bunyavirus family members, including Asian and South American hantaviruses (Hantaan virus and Andes virus, Crimean-Congo hemorrhagic fever virus, La Crosse virus, and Rift Valley fever virus. The pharmacokinetic profile of FGI-106 revealed sufficient exposure of the drug to critical target organs (lung, liver, kidney, and spleen, which are frequently the sites of bunyavirus replication. Consistent with these findings, FGI-106 treatment delivered via intraperitoneal injection prior to virus exposure was sufficient to delay the onset of Rift Valley fever virus infection in mouse-based models and to enhance survival in the face of an otherwise lethal infection. Altogether, these results suggest a potential opportunity for the use of FGI-106 to treat infections by members of the family Bunyaviridae.Keywords: Rift Valley fever virus, bunyavirus, hantavirus, antiviral, therapeutic

  18. Evolutionary aspects of functional and pseudogene members of the phytochrome gene family in Scots pine.

    According to the neutral theory of evolution, mutation and genetic drift are the only forces that shape unconstrained, neutral, gene evolution. Thus, pseudogenes (which often evolve neutrally) provide opportunities to obtain direct estimates of mutation rates that are not biased by selection, and gene families comprising functional and pseudogene members provide useful material for both estimating neutral mutation rates and identifying sites that appear to be under positive or negative selection pressures. Conifers could be very useful for such analyses since they have large and complex genomes. There is evidence that pseudogenes make significant contributions to the size and complexity of gene families in pines, although few studies have examined the composition and evolution of gene families in conifers. In this work, I examine the complexity and rates of mutation of the phytochrome gene family in Pinus sylvestris and show that it includes not only functional genes but also pseudogenes. As expected, the functional PHYO does not appear to have evolved neutrally, while phytochrome pseudogenes show signs of unconstrained evolution.

    Lesch-Nyhan disease is an inborn error of purine metabolism that results from deficiency of the activity of hypoxanthine phosphoribosyltransferase (HPRT). The heterogeneity of clinical phenotypes seen in HPRT deficiency corresponds to an inverse relationship between HPRT enzyme activity and clinical severity. With rare exception, each mutation produces a stereotypical pattern of clinical disease; onset of neurologic symptoms occurs during infancy and is thought to be nonprogressive. To document a family in which a single HPRT gene mutation has led to 3 different clinical and enzymatic phenotypes. Case report. Settings A university-based outpatient metabolic clinic and a biochemical genetics laboratory. Patients Three males (2 infants and their grandfather) from the same family with Lesch-Nyhan variant, including one of the oldest patients with Lesch-Nyhan variant at diagnosis (65 years). Clinical and biochemical observations. Sequencing of 5 family members revealed a novel mutation c.550G>T in exon 7 of the HPRT gene. The considerably variable clinical phenotype corresponded with the variable enzymatic activity in the 3 males, with the grandfather being the most severely affected. The different phenotypes encountered in the enzymatic analysis of cultured fibroblasts from a single mutation in the same family is unprecedented. The significant decrease in the grandfather's HPRT enzymatic activity compared with that of his grandchildren could be a function of the Hayflick Limit Theory of cell senescence.

    Full Text Available Objective: To evidence knowledge published in the field of nursing care on the embracement to family members of people in psychic suffering in health services. Methods: Integrative review, accomplished in June and July 2012, in LILACS, BDENF, IBECS, MEDLINE and SciELO databases, using the keywords: “mental health”, “user embracement” and “family”. The inclusion criteria were met by 14 texts, written by professionals and nursing students, in Portuguese language, published between 2007 and 2011. The data was resumed in four tables and a figure, and analyzed under the framework of the user embracement by the National Humanization Policy. Results: No trends related to studies on user embracement can be stated. Most publications adopt a qualitative approach and content analysis, with evidence being type III. There is a predominance of research having health professionals as subjects. However, the family and other actors are starting to get involved. Taking similar care of the family and the person in suffering is highlighted in all of the studies analyzed. It was evidenced need for interaction between the health services and the specialized mental health network and for training the team in order to minimize to the difficulties faced by the family. Conclusion: Family embracement was often pointed as a device that facilitates the rehabilitation. There is much to be done toward its embracement in health services, so that the family is allowed to realize that their living is not necessarily the continuity of the trouble faced by the other person. doi:http://dx.doi.org/10.5020/18061230.2013.p571

    The study purpose was to understand the perspectives of bereaved family members regarding palliative care unit (PCU) and palliative care and to compare perceptions of PCU before admission and after bereavement. A cross-sectional questionnaire survey was conducted, and the perceptions of 454 and 424 bereaved family members were obtained regarding PCU and palliative care, respectively. Family members were significantly more likely to have positive perceptions after bereavement (ranging from 73% to 80%) compared to before admission (ranging from 62% to 71%). Bereaved family members who were satisfied with medical care in the PCU had a positive perception of the PCU and palliative care after bereavement. Respondents younger than 65 years of age were significantly more likely to have negative perceptions of PCU and palliative care.

    2015-06-01

    The endoplasmic reticulum (ER) is an essential cellular compartment in which an enormous number of secretory and cell surface membrane proteins are synthesized and subjected to cotranslational or posttranslational modifications, such as glycosylation and disulfide bond formation. Proper maintenance of ER protein homeostasis (sometimes termed proteostasis) is essential to avoid cellular stresses and diseases caused by abnormal proteins. Accumulating knowledge of cysteine-based redox reactions catalyzed by members of the protein disulfide isomerase (PDI) family has revealed that these enzymes play pivotal roles in productive protein folding accompanied by disulfide formation, as well as efficient ER-associated degradation accompanied by disulfide reduction. Each of PDI family members forms a protein-protein interaction with a preferential partner to fulfill a distinct function. Multiple redox pathways that utilize PDIs appear to function synergistically to attain the highest quality and productivity of the ER, even under various stress conditions. This review describes the structures, physiological functions, and cooperative actions of several essential PDIs, and provides important insights into the elaborate proteostatic mechanisms that have evolved in the extremely active and stress-sensitive ER.

    Acedo, Pilar; Zawacka-Pankau, Joanna

    2015-08-01

    TP53 is one of the genes most frequently inactivated in cancers. Mutations in TP53 gene are linked to worse prognosis and shorter overall survival of cancer patients. TP53 encodes a critical tumor suppressor, which dictates cell fate decisions upon stress stimuli. As a sensor of cellular stress, p53 is a relevant messenger of cell death signaling in ROS-driven photodynamic therapy (PDT) of cancer. The significant role of p53 in response to PDT has been reported for several clinically approved photosensitizers. Multiple reports described that wild-type p53 contributes to cell killing upon photodynamic therapy with clinically approved photosensitizers but the mechanism is still not fully understood. This work outlines the diverse functions of p53 family members in cancer cells' susceptibility and resistance to PDT. In summary p53 and p53 family members are emerging as important mediators of cell death signaling in photodynamic therapy of cancer, however the mechanism of cell death provoked during PDT might differ depending on the tissue type and the photosensitizer applied.

    Living with an adult family member using advanced medical technology at home An increased number of chronically ill adults perform self-care while using different sorts of advanced medical technology at home. This hermeneutical study aimed to gain a deeper understanding of the meaning of living with an adult family member using advanced medical technology at home. Eleven next of kin to adults performing self-care at home, either using long-term oxygen from a cylinder or ventilator, or performing peritoneal or haemodialysis, were interviewed. The qualitative interviews were analysed using a Gadamerian methodology. The main interpretation explained the meaning as rhythmical patterns of connectedness versus separation, and of sorrow versus reconciliation. Dependence on others was shown in the need for support from healthcare professionals and significant others. In conclusion, next of kin took considerable responsibility for dependent-care. All next of kin were positive to the idea of bringing the technology home, even though their own needs receded into the background, while focusing on the best for the patient. The results were discussed in relation to dependent-care and transition, which may have an influence on the self-care of next of kin and patients. The study revealed a need for further nursing attention to next of kin in this context.

    Fibroblast Growth Factor (FGF) Receptors (FGFRs) regulate essential biological processes, including embryogenesis, angiogenesis, cellular growth and memory-related long-term synaptic plasticity. Whereas canonical FGFRs depend exclusively on extracellular Immunoglobulin (Ig)-like domains for ligand binding, other receptor types, including members of the tropomyosin-receptor-kinase (Trk) family, use either Ig-like or Leucine-Rich Repeat (LRR) motifs, or both. Little is known, however, about the evolutionary events leading to the differential incorporation of LRR domains into Ig-containing tyrosine kinase receptors. Moreover, although FGFRs have been identified in many vertebrate species, few reports describe their existence in invertebrates. Information about the biological relevance of invertebrate FGFRs and evolutionary divergences between them and their vertebrate counterparts is therefore limited. Here, we characterized ApLRRTK, a neuronal cell-surface protein recently identified in Aplysia. We unveiled ApLRRTK as the first member of the FGFRs family deprived of Ig-like domains that instead contains extracellular LRR domains. We describe that ApLRRTK exhibits properties typical of canonical vertebrate FGFRs, including promotion of FGF activity, enhancement of neuritic outgrowth and signaling via MAPK and the transcription factor CREB. ApLRRTK also enhanced the synaptic efficiency of neurons known to mediate in vivo memory-related defensive behaviors. These data reveal a novel molecular regulator of neuronal function in invertebrates, provide the first evolutionary linkage between LRR proteins and FGFRs and unveil an unprecedented mechanism of FGFR gene diversification in primeval central nervous systems.

    Zinc fingers and homeoboxes (ZHX) is a transcription repressor family that contains three members; ZHX1, ZHX2, and ZHX3. Although ZHX family members have been associated with the progression of cancer, their values as prognostic factors in cancer patients have been poorly examined. Renal cell carcinoma (RCC) is a highly heterogeneous, aggressive cancer that responds variably to treatment. Thus, prognostic molecular markers are required to evaluate disease progression and to improve the survival. In clear cell RCC (ccRCC), ZHX1 and ZHX3 expression were found to be down-regulated but ZHX2 was up-regulated, and the expressions of ZHX1 and ZHX3 were significantly associated with pathological stage. Furthermore, Kaplan-Meier and multivariate regression analysis showed that reduction in the mRNA expression of ZHX1 was associated with poorer survival. Taken together, the present study shows loss of ZHX1 is correlated with ccRCC progression and suggests it is an independent prognostic marker in ccRCC. PMID:28152006

    Recently we reported on the characterization of an archaeal member of the amidohydrolase superfamily, namely Sulfolobus acidocaldarius lactonase, showing low but significant and extremely thermostable paraoxonase activity. This enzyme, that we have named SacPox, is a member of the new described family of phosphotriesterase-like lactonases (PLLs). In this family the binuclear metal centre, which is involved in the catalytic machinery, has been poorly studied up to now. In this work we describe the expression of the protein in presence of different metals showing Mn(2+) to support the higher activity. The enzyme has been over-expressed, purified and characterized as a Mn(2+)-containing enzyme by inductive plasma coupled mass spectrometry (ICP-MS), showing also surprising kinetic differences in comparison with the cadmium-containing enzyme. The Mn(2+) containing enzyme was about 30-fold more efficient with paraoxon as substrate and more stable than the Cd(2+) counterpart, even though the Mn(2+) affinity for the binuclear metal centre is apparently lower. These results increase our knowledge of the biochemical characteristics of SacPox mainly with regard to the metal-ions modulation of function. Copyright © 2012 Elsevier Ireland Ltd.

    Members of the fungal-specific velvet protein family regulate sexual and asexual spore production in the Ascomycota. We predicted, therefore, that velvet homologs in the basidiomycetous plant pathogen Ustilago maydis would regulate sexual spore development, which is also associated with plant disease progression in this fungus. To test this hypothesis, we studied the function of three U. maydis velvet genes, umv1, umv2 and umv3. Using a gene replacement strategy, deletion mutants were made in all three genes in compatible haploid strains, and additionally for umv1 and umv2 in the solopathogenic strain, SG200. None of the mutants showed novel morphological phenotypes during yeast-like, in vitro growth. However, the Δumv1 mutants failed to induce galls or teliospores in maize. Chlorazol black E staining of leaves infected with Δumv1 dikaryons revealed that the Δumv1 hyphae did not proliferate normally and were blocked developmentally before teliospore formation. The Δumv2 mutants were able to induce galls and teliospores in maize, but were slow to do so and thus reduced in virulence. The Δumv3 mutants were not affected in teliospore formation or disease progression. Complementation of the Δumv1 and Δumv2 mutations in the SG200 background produced disease indices similar to those of SG200. These results indicate that two U. maydis velvet family members, umv1 and umv2, are important for normal teliospore development and disease progression in maize seedlings.

    Entamoeba histolytica is the cause of amebic colitis and liver abscess. This parasite induces apoptosis in host cells and utilizes exposed ligands such as phosphatidylserine to ingest the apoptotic corpses and invade deeper into host tissue. The purpose of this work was to identify amebic proteins involved in the recognition and ingestion of dead cells. A member of the transmembrane kinase family, phagosome-associated TMK96 (PATMK), was identified in a proteomic screen for early phagosomal proteins. Anti-peptide affinity-purified antibody produced against PATMK demonstrated that it was a type I integral membrane protein that was expressed on the trophozoite surface, and that co-localized with human erythrocytes at the site of contact. The role of PATMK in erythrophagocytosis in vitro was demonstrated by: (i) incubation of ameba with anti-PATMK antibodies; (ii) PATMK mRNA knock-down using a novel shRNA expression system; and (iii) expression of a carboxy-truncation of PATMK (PATMKΔ932). Expression of the carboxy-truncation of PATMKΔ932 also caused a specific reduction in the ability of E. histolytica to establish infection in the intestinal model of amebiasis, however these amebae retained the ability to cause hepatic abscesses when directly injected in the liver. In conclusion, PATMK was identified as a member of the TMK family that participates in erythrophagocytosis and is uniquely required for intestinal infection. PMID:18208324

  12. Regulation of the MAPK family members: role of subcellular localization and architectural organization.

    The members of the mitogen-activated protein kinase (MAPK) family are regulated by a diverse array of extracellular cues ranging from cytokines, growth factors and neuropeptides, which activate cell surface receptors, to stresses such as cold, heat, osmolarity changes and irradiation. The MAPK pathways control genetic expression by modifying transcription factor activity and cue important cell fate decisions including survival, proliferation, and programmed cell death (apoptosis). One interesting feature of the MAPK pathways is that the components are evolutionarily conserved from yeast to human, and many of the pathways are similarly organized and regulated. Unlike previously imagined, architectural organization or the multimeric organization of signaling proteins into complexes which are localized to distinct subcellular regions is an important mechanism that influences the regulation of these pathways. In addition, extracellular stimuli can induce relocalization of specific signal transduction proteins. The formation of multimeric signaling complexes, as well as the dynamic movement of signaling proteins, contribute to determine signaling specificity and efficacy. This review describes what is currently known about the subcellular localization of MAPK pathway signaling proteins and the relocalization that occurs during events associated with activation of the MAPK family members.

    Selected antiapoptotic genes were expressed in baker's yeast (Saccharomyces cerevisiae) to evaluate cytoprotective effects during oxidative stress. When exposed to treatments resulting in the generation of reactive oxygen species (ROS), including H(2)O(2), menadione, or heat shock, wild-type yeast died and exhibited apoptotic-like characteristics, consistent with previous studies. Yeast strains were generated expressing nematode ced-9, human bcl-2, or chicken bcl-xl genes. These transformants tolerated a range of oxidative stresses, did not display features associated with apoptosis, and remained viable under conditions that were lethal to wild-type yeast. Yeast strains expressing a mutant antiapoptotic gene (bcl-2 deltaalpha 5-6), known to be nonfunctional in mammalian cells, were unable to tolerate any of the ROS-generating insults. These data are the first report showing CED-9 has cytoprotective effects against oxidative stress, and add CED-9 to the list of Bcl-2 protein family members that modulate ROS-mediated programmed cell death. In addition, these data indicate that Bcl-2 family members protect wild-type yeast from physiological stresses. Taken together, these data support the concept of the broad evolutionary conservation and functional similarity of the apoptotic processes in eukaryotic organisms.

    Cestrum yellow leaf curling virus (CmYLCV) has been characterized as the aetiological agent of the Cestrum parqui mosaic disease. The virus genome was cloned and the clone was proven to be infectious to C. parqui. The presence of typical viroplasms in virus-infected plant tissue and the information obtained from the complete genomic sequence confirmed CmYLCV as a member of the Caulimoviridae family. All characteristic domains conserved in plant pararetroviruses were found in CmYLCV. Its genome is 8253 bp long and contains seven open reading frames (ORFs). Phylogenetic analysis of the relationships with other members of the Caulimoviridae revealed that CmYLCV is closely related to the Soybean chlorotic mottle virus (SbCMV)-like genus and particularly to SbCMV. However, in contrast to the other members of this genus, the primer-binding site is located in the intercistronic region following ORF Ib rather than within this ORF, and an ORF corresponding to ORF VII is missing.

    to identify the coping strategies of family members of patients with mental disorders and relate them to family member sociodemographic variables and to the patient's clinical variables. this was a descriptive study conducted at a psychiatric hospital in the interior of the state of São Paulo, with 40 family members of hospitalized patients over the age of 18, and who followed the patient before and during hospitalization. We used tools to characterize the subjects and the Folkman and Lazarus Inventory of Coping Strategies. the coping strategies most often used by family members were social support and problem solving. Mothers and fathers used more functional strategies (self-control p=0.037, positive reappraisal p=0.037, and social support p=0,021). We found no significant differences between the strategies and other variables examined. despite the suffering resulting from the illness of a dear one, family members make more use of functional strategies, allowing them to cope with adversities in a more well-adjusted way. identificar as estratégias de enfrentamento de familiares de pacientes com transtornos mentais e relacioná-las com as variáveis sociodemográficas do familiar e clínicas do paciente. estudo descritivo, desenvolvido em hospital psiquiátrico do interior do estado de São Paulo, com 40 familiares de pacientes internados, maiores de 18 anos e que acompanhavam o paciente antes e durante a internação.

    Full Text Available Purpose: To describe the potential role of the Internet as a vehicle for improving integration of care through activating chronic kidney disease patients and their family members. Also, to describe how that potential is being developed through a website sponsored by the Medicare program in the United States. Background: The Internet is expanding at a rapid rate, and health-related websites are one of its most popular features. Efforts to promote integration of care have focused mainly on providers up to now, and more emphasis is needed on the potential roles of patients. Chronically ill patients have particular needs for improved education about their conditions and enhanced involvement in care planning and treatment decisions. Medicare developed the Dialysis Facility Compare website to serve those goals for people with chronic kidney disease. Methods: We conducted qualitative research with 140 chronic kidney disease patients and family members, and 130 renal care professionals to evaluate and improve the Dialysis Facility Compare website. A series of 19 focus groups, 13 triads (small focus groups, and 56 individual interviews were conducted in four regions of the United States and by telephone. Results: We found that the Dialysis Facility Compare website has the potential to improve integration of care for people with chronic kidney disease in at least three ways. First: by expanding the roles of patients as members of the multi-disciplinary team of caregivers treating their disease. Second: through better integration of the informal care provided in the home and community with the formal care provided by health professionals. Third: by improving coordination of between care provided in the pre-dialysis and dialysis phases of the disease. Discussion: We developed recommendations for revising and enhancing the Dialysis Facility Compare website in a number of ways to better promote patient activation and integration of care.

    The purpose of this study is to compare the agreement in opinion between the elderly in care facilities and their family members regarding the life-sustaining treatment at the deathbed and to find out if the intentions of the elderly are being properly reflected in their deathbed treatment. Data were collected from 85 elderly individuals at five care facilities in Chunkcheongnam-do and 85 family members. The data were collected with a self-administered questionnaire from July 22, 2013 to August 15, 2014. A total of 170 cases were analyzed using SPSS version 21. First, the family members' preference for life-sustaining treatment was higher than the patients' preference. The preference between the elderly and their family members regarding life-sustaining treatment was statistically significant with regards to oral nutrition, pain control through oral and anal administration, pain control through intravenous administration, transfusion, and admission to an intensive care unit. Second, looking at the agreement between elderly and guardians regarding life-sustaining treatment, there was significant concordance about general testing, oral nutrition, intravenous hydration, intravenous nutrition, antibiotic treatment for severe infection with low resiliency, admission to an intensive care unit, blood pressure increase medication use, cardiopulmonary resuscitation, and tracheotomy. It is essential for the medical staff to confirm agreement between the elderly and their family members regarding life-sustaining treatment, and if such a prior agreement is not feasible, the patient's intention should be considered more actionable than their family members.

  1. Family members' obstructive behaviors appear to be more harmful among adults with type 2 diabetes and limited health literacy.

    Family members' diabetes-specific obstructive behaviors (e.g., nagging/arguing or getting in the way of patients' self-care) are associated with adults having worse glycemic control (HbA1C), with diabetes-specific supportive family behaviors protecting against this detrimental effect. Given the role of family members in helping patients with limited health literacy, patients' health literacy status may moderate these relations. The authors tested this hypothesis with 192 adults with type 2 diabetes. Twenty-six percent had limited health literacy, and limited health literacy was associated with more supportive family behaviors (pliteracy and low supportive family behaviors than for participants with adequate health literacy and low supportive family behaviors (adjusted simple slopes β=0.70, p=.05 vs. β=0.36, p=.009). However, there was no association between obstructive family behaviors and HbA1C in the context of high supportive family behaviors, regardless of health literacy status. Involving family members in adults' self-care without teaching them to avoid obstructive behaviors may be particularly harmful for patients with limited health literacy. Future research should identify intervention content to reduce obstructive family behaviors and identify which supportive family behaviors may be protective.

    Patients with endotracheal intubation often experience anxiety because they are unable to express their needs freely. However, the family members of these patients are able to provide encouragement, comfort, and substantive support. The aims of the present study were: (1) to compare the anxiety scores, vital signs, and incidence of unplanned extubation (UE) between the two comparison groups; (2) to compare the differences in vital signs before and after the intervention in the experimental group; and (3) to explore the satisfaction of patients in the experimental group with the intervention. A quasi-experimental, pretest-posttest design was carried out. A convenience sampling was adopted to recruit patients with endotracheal intubation in intensive care units (ICUs). The experimental group listened to the UE-prevention reminders of their family members for three times a day for 4 days. The control group was provided with usual care. (1) No significant difference was observed in the anxiety scores between the two groups (t = -1.282, p = .205). (2) A repeated-measures analysis found no significant difference in vital signs, taken nightly at 10 p.m., between the experimental and control groups (p > .05). (3) The experimental group registered significantly lower heart rates, systolic blood pressure, diastolic blood pressure, and mean arterial pressure after the conclusion of the intervention (p family reminders encouraging and reminding patients about intubation safety, achieved a very high level of patient satisfaction and reduced their anxiety-related vital signs. The results may serve as a reference for providing intervention treatment to patients with endotracheal intubation in ICUs.

  3. Evolutionary, structural and functional interplay of the IκB family members.

    Full Text Available A primary level of control for nuclear factor kappa B (NF-κB is effected through its interactions with the inhibitor protein, inhibitor of kappa B (IκB. Several lines of evidence confirm the existence of multiple forms of IκB that appear to regulate NF-κB by distinct mechanisms. Therefore, we performed a comprehensive bioinformatics analysis to understand the evolutionary history and intrinsic functional diversity of IκB family members. Phylogenetic relationships were constructed to trace the evolution of the IκB family genes. Our phylogenetic analysis revealed 10 IκB subfamily members that clustered into 5 major clades. Since the ankyrin (ANK domain appears to be more ancient than the Rel homology domain (RHD, our phylogenetic analysis suggests that some undefined ancestral set of ANK repeats acquired an RHD before any duplication and was later duplicated and then diverged into the different IκB subfamilies. Functional analysis identified several functionally divergent sites in the ANK repeat domains (ARDs and revealed that this region has undergone strong purifying selection, suggesting its functional importance in IκB genes. Structural analysis showed that the major variations in the number of ANK repeats and high conformational changes in the finger loop ARD region contribute to the differing binding partner specificities, thereby leading to distinct IκB functions. In summary, our study has provided useful information about the phylogeny and structural and functional divergence of the IκB family. Additionally, we identified a number of amino acid sites that contribute to the predicted functional divergence of these proteins.

    Full Text Available Bid is the only known Bcl-2 family member that can function as an agonist of proapoptotic Bcl-2-related proteins such as Bax and Bak. Expression of the proapoptotic Bcl-2 family protein Bid was assessed by immunoblotting and immunohistochemical methods in normal murine and human tissues, and in several types of human cancers and tumor cell lines. Bid expression in normal tissues varied widely, with prominent Bid immunostaining occurring in several types of short-lived cells (e.g., germinal center B cells, peripheral blood granulocytes, differentiated keratinocytes and in apoptosissensitive cells (e.g., adult neurons. Analysis of Bid expression by immunostaining of 100 colon, 95 ovarian, and 254 prostate cancers, as well as 59 brain tumors and 50 lymphomas, revealed evidence of altered Bid regulation in sometypes of cancers. Correlations with clinical outcome data revealed association of higher levels of Bid with longer recurrence-free survival in men with locally advanced (T3 stage prostate cancer (P=0.04. Immunoblot analysis of Bid protein levels in the NCI's panel of 60 human tumor cell lines revealed a correlation between higher levels of Bid and sensitivity to ribonucleotide reductase (RR-inhibiting drugs (P<0.0005. Overexpression of Bid in a model tumor cell line by gene transfection resulted in increased sensitivity to apoptosis induction by a RR inhibitor. Taken together, these observations suggest a potential role for Bid in tumor responses to specific chemotherapeutic drugs, and lay a foundation for future investigations of this member of the Bcl-2 family in healthy and diseased tissues.

    2016-12-01

    Eight beetle species of the superfamily Scarabaeoidea were investigated with respect to peptides belonging to the adipokinetic hormone (AKH) family in their neurohemal organs, the corpora cardiaca (CC). The following beetle families are represented: Scarabaeidae, Lucanidae, and Geotrupidae. AKH peptides were identified through a heterospecific trehalose-mobilizing bioassay and by sequence analyses, using liquid chromatography coupled to positive electrospray mass spectrometry (LC-ESI-MS) and analysis of the tandem MS(2) spectra obtained by collision-induced dissociation. All the beetle species have octapeptide AKHs; some have two AKHs, while others have only one. Novel AKH members were found in Euoniticellus intermedius and Circellium bacchus (family Scarabaeidae), as well as in Dorcus parallelipipedus (family Lucanidae). Two species of the family Geotrupidae and two species of the Scarabaeidae subfamily Cetoniinae contain one known AKH peptide, Melme-CC, while E. intermedius produces a novel peptide code named Euoin-AKH: pEINFTTGWamide. Two AKH peptides were each identified in CC of C. bacchus and D. parallelipipedus: the novel Cirba-AKH: pEFNFSAGWamide and the known peptide, Scade-CC-I in the former, and the novel Dorpa-AKH: pEVNYSPVW amide and the known peptide, Melme-CC in the latter. Kheper bonelli (subfamily Scarabaeinae) also has two AKHs, the known Scade-CC-I and Scade-CC-II. All the novel peptides were synthesized and the amino acid sequence assignments were unequivocally confirmed by co-elution of the synthetic peptides with their natural equivalent, and identical MS parameters of the two forms. The novel synthetic peptides are all active in inducing hypertrehalosemia in cockroaches.

    2007-01-01

    We have witnessed a dramatic increase in the frequency and diversity of herbicide-resistant weed biotypes over the past two decades, which poses a threat to the sustainability of agriculture at both local and global levels. In addition, non-target-site mechanisms of herbicide resistance seem to be increasingly implicated. Non-target-site herbicide resistance normally involves the biochemical modification of the herbicide and/or the compartmentation of the herbicide (and its metabolites). In contrast to herbicide target site mutations, fewer non-target mechanisms have been elucidated at the molecular level because of the inherently complicated biochemical processes and the limited genomic information available for weedy species. To further understand the mechanisms of non-target-site resistance, we propose an integrated genomics approach to dissect systematically the functional genomics of four gene families in economically important weed species.

    Full Text Available Nhi Huynh, Hong He Department of Surgery, University of Melbourne, Austin Health, Melbourne, VIC, Australia Abstract: The p21-activated kinase (PAK family of serine/threonine protein kinases are downstream effectors of the Rho family of GTPases. PAKs are frequently upregulated in human diseases, including various cancers, and their overexpression correlates with disease progression. Current research findings have validated important roles for PAKs in cell proliferation, survival, gene transcription, transformation, and cytoskeletal remodeling. PAKs are shown to act as a converging node for many signaling pathways that regulate these cellular processes. Therefore, PAKs have emerged as attractive targets for treatment of disease. This review discusses the physiological and pathological roles of PAKs, validation of PAKs as new promising drug targets, and current challenges and advances in the development of PAK-targeted anticancer therapy, with a focus on PAKs and human cancers.

    Almost two-thirds of the 110,000 people living with dementia in Switzerland receive home care from family members. Outreach counselling can reduce the burden for family caregivers and delay nursing home placement. However, little is known of how this works and how caregivers experience the counselling. The Canton of Aargau Alzheimer's Association has been conducting a pilot project to demonstrate the necessity, effectiveness and practicability of outreach counselling in (their canton). As a part of the evaluation of the project this study explored how family members experience the process of caring for a relative with dementia and outreach counselling. Interpretive phenomenology–a qualitative approach–was used to analyse data from interviews with twelve family caregivers. Most family members felt supported in caregiving by outreach counselling. Three aspects of the counselling were especially important to the participants: being understood and taken seriously by the counsellor; receiving answers to their most pressing questions concerning the illness and being supported when difficult decision had to be taken; regaining personal time and learning how to better interact with the person with dementia. Two participants would have wished for more help by the counsellor. To meet the needs of the family members, consultants should have sufficient experience in dementia patient care and should be strongly networked across the local health and welfare system. This study shows that family members can experience outreach counselling as a great support in their caregiving roles.

    Full Text Available Parasitism experienced early in ontogeny can have a major impact on host growth, development and future fitness, but whether siblings are affected equally by parasitism is poorly understood. In birds, hatching asynchrony induced by hormonal or behavioural mechanisms largely under parental control might predispose young to respond to infection in different ways. Here we show that parasites can have different consequences for offspring depending on their position in the family hierarchy. We experimentally treated European Shag (Phalacrocorax aristoteli nestlings with the broad-spectrum anti-parasite drug ivermectin and compared their growth rates with nestlings from control broods. Average growth rates measured over the period of linear growth (10 days to 30 days of age and survival did not differ for nestlings from treated and control broods. However, when considering individuals within broods, parasite treatment reversed the patterns of growth for individual family members: last-hatched nestlings grew significantly slower than their siblings in control nests but grew faster in treated nests. This was at the expense of their earlier-hatched brood-mates, who showed an overall growth rate reduction relative to last-hatched nestlings in treated nests. These results highlight the importance of exploring individual variation in the costs of infection and suggest that parasites could be a key factor modulating within-family dynamics, sibling competition and developmental trajectories from an early age.

  11. Retroelements versus APOBEC3 family members: No great escape from the magnificent seven

    Directory of Open Access Journals (Sweden)

    2012-08-01

    Full Text Available Retroelements comprise a large and successful family of transposable genetic elements that, through intensive infiltration, have shaped the genomes of humans and other mammals over millions of years. In fact, retrotransposons now account for approximately 45% of the human genome. Based on their genomic mobility, some retroelements are known to be the cause of genetic diseases, not only in germ and embryonic stem cells but also in somatic cells, posing a threat to genomic stability throughout all cellular populations. In response, mammals have developed intrinsic immunity mechanisms that provide resistance against the threat of the deleterious effects of retrotransposition. Among these, seven members of the APOBEC3 (A3 family of cytidine deaminases serve as highly active, intrinsic, antiretroviral host factors. Certain A3 proteins effectively counteract infections of retroviruses such as HIV-1, as well as those of other virus families, while also blocking the transposition of retroelements. Based on their preferential expression in the germ cells, in which retrotransposons may be active, it is likely that A3 proteins were acquired through mammalian evolution primarily to inhibit retrotransposition and thereby maintain genomic stability in these cells. This review summarizes the recent advances in our understanding of the interplay between the retroelements currently active in the human genome and the anti-retroelement A3 proteins.

    Oral history makes a critical contribution in articulating the perspectives of people often overlooked in histories written from the standpoint of dominating class, gender, ethnic or professional groups. Using three interrelated approaches - life stories, oral history, and narrative analysis - this paper analyzes family responses to psychiatric care and mental illness in oral history interviews with family members who experienced mental illness themselves or within their family between 1930 and 1975. Interviews with three family members in Alberta, Canada are the primary focus. These stories provide an important avenue to understand the meaning and transformations of mental health-care from the point of view of families. Family members' stories reveal contradictory responses to the dominant cultural discourse. Using a performative framework of interpretation, the narratives reveal a complex interplay between medical, social and cultural conceptions of mental illness, deepening our understanding of its meaning. The history of mental health-care can be substantially enriched by the analysis of family members' stories, not only revealing the constructed nature of mental illness, but also illustrating the family as a mediating context in which the meaning of mental illness is negotiated.

    BACKGROUND: The Quality of Dying and Death (QODD) questionnaire is used as a self-reported measure to allow families and clinicians to assess patients' quality of dying and death. We evaluated end-of-life (EOL) experiences as measured by the QODD completed by families and nurses in the United...... States (US) and the Netherlands (NL) to explore similarities and differences in these experiences and identify opportunities for improving EOL care. METHODS: Questionnaire data were gathered from family members of patients dying in the ICU and nurses caring for these patients. In NL, data were gathered.......0025). The family-assessed overall QODD score (medians [IQR]) was the same in both countries: NL 9 [8-10], US 8[5-10]. US family members rated the quality of two items higher than NL families: "time spent with loved ones" and "time spent alone". Nurse-assessed QODD ratings varied: the single-item QODD summary score...

    The biological function and evolutionary diversity of the mitogen-activated protein kinase (MAPK) family have mostly been studied in fungi, animals and plants, with very limited information from lower eukaryotes. This study aimed to describe the MAPKs of unicellular Tetrahymena thermophila. Eight members of the T. thermophila MAPK (TtMPK) gene family, in addition to previously reported TtMPK1, TtMPK2 and TtMPK3, were identified bioinformatically using a T. thermophila genome database. Phylogenetic analysis assigned the TtMPKs into two major groups, ERK1/2-like (TtMPK1, 2, 3, 5, 6, 7, 8, and 9) as stress-responsive MAPKs for biotic and abiotic stresses, and ERK7/8-like (TtMPK4, 10, and 11) as cell-cycle-associated protein kinases for biotic factors. Semi-quantitative RT-PCR analysis of the TtMPKs showed high mRNA expression at 30°C; however, only TtMPK5 and TtMPK6 showed high expression at 37°C. Osmotic shock by 100mM NaCl only increased the expression of TtMPK2, whereas 20mM NaCl reduced the expression of all MPKs to almost zero. The results suggested that T. thermophila MAPKs are among the closest representatives of the ancestors of the eukaryotic MAPK family. Although no functional characterization of MPKs was performed, this study is the first report of the genome-wide MAPK family in T. thermophila. Copyright © 2014 Elsevier GmbH. All rights reserved.

    Health professionals and public health experts in maternal and newborn health encourage women to deliver at health facilities in an effort to reduce maternal and newborn mortality. In the existing literature, there is scant information on how migration, family members and community influence facility delivery. This study addresses this knowledge gap using 10 years of longitudinal surveillance data from a rural district of Tanzania. Multilevel logistic regression was used to quantify the influence of hypothesized migration, family and community-level factors on facility delivery while adjusting for known confounders identified in the literature. We report adjusted odds ratios (AOR). Overall, there has been an increase of 14% in facility delivery over the ten years, from 63% in 2001 to 77% in 2010 (p community were more likely to give birth in a facility AOR = 1.2 (95% CI 1.11-1.29). Furthermore, the previous facility delivery of sisters and sisters-in-law has a significant influence on women's facility delivery; AOR = 1.29, 95% CI 1.15-1.45 and AOR = 1.7, 95% CI 1.35-2.13 respectively. Community level characteristics play a role as well; women in communities with higher socioeconomic status and older women of reproductive age had increased odds of facility delivery; AOR = 2.37, 95% CI 1.88-2.98 and AOR = 1.17, 95% CI 1.03-1.32 respectively. Although there has been an increase in facility delivery over the last decade in Rufiji, this study underscores the importance of female migrants, family members and community in influencing women's place of delivery. The findings of this study suggest that future interventions designed to increase facility delivery must integrate person-to-person facility delivery promotion, especially through women of the community and within families. Furthermore, the results suggest that investment in formal education of the community and increased community socio-economic status may increase facility delivery.

    Forgiveness has begun to receive empirical attention in end-of-life contexts, but primarily among patients. This study examined forgiveness issues and communication priorities among family members of hospice patients. Surveys were distributed to family members of home-care patients in a large not-for-profit hospice in the Great Lakes region of the United States. Family members wrote what they would like to say to patients before they died. They also rated the importance of several expressions (love, gratitude, giving and seeking forgiveness, saying farewell) and the extent to which they had already expressed these messages. Participants rated their depressive symptoms and the quantity of unresolved offenses committed by themselves and the patient. Of 147 surveys returned by participants, 142 were usable. In comparison with forgiveness-related communications, expressions of love, gratitude, and farewell were more consistently rated important; yet many participants rated forgiveness (giving and seeking) as extremely important. If forgiveness was rated important but had not been fully expressed, participants reported more depressive symptoms (plove and gratitude, forgiveness-related communications are seen as extremely important by many family members of hospice patients. If family members see forgiveness (granting or seeking) as important but have not completed the process, these unresolved issues are associated with depressive symptoms. This study suggests that unresolved offenses and forgiveness issues warrant assessment and clinical attention within families receiving hospice care.

    The rare inherited condition acrodermatitis enteropathica (AE) results from a defect in the absorption of dietary zinc. Recently, we used homozygosity mapping in consanguineous Middle Eastern kindreds to localize the AE gene to an approximately 3.5-cM region on 8q24. In this article, we identify a gene, SLC39A4, located in the candidate region and, in patients with AE, document mutations that likely lead to the disease. The gene encodes a histidine-rich protein, which we refer to as "hZIP4," which is a member of a large family of transmembrane proteins, some of which are known to serve as zinc-uptake proteins. We show that Slc39A4 is abundantly expressed in mouse enterocytes and that the protein resides in the apical membrane of these cells. These findings suggest that the hZIP4 transporter is responsible for intestinal absorption of zinc.

    Metal-organic porous sheets, due to their unique atomic configurations and properties, represent a class of materials beyond graphene and BN monolayers. The Mo2-phthalocyanine-based sheet (Mo2Pc) is a new member of this porous organometallic family. Using density functional theory with hybrid functional for exchange-correlation potential, we show that this dimer-based material, unlike conventional organic monolayers that contain isolated metal atoms, possesses unique mechanical, magnetic, electronic, and optical properties due to inherent anisotropy in the structure. Furthermore, it is a semiconductor with a direct band gap of 0.93 eV and is antiferromagnetic with each Mo site carrying a magnetic moment of 0.88 μB. The strong anisotropy in elasticity and infrared light absorption is likely to open new doors for potential applications.

    The purpose of this study was to review current principles of therapy for affected patients and determine whether an emergent surgical approach or expectant management should be selected in cases of snakebites of fingers or toes by Viperidae family members. Over the past five years (January 2004 to December 2009), 12 patients bitten by Vipera ammodytes were admitted in our department. We retrospectively reviewed their demographic and epidemiological characteristics as well as their symptoms, laboratory findings, and complications. All snake bites occurred at the extremities (fingers and toes). The main complications were oedema, disseminated intravascular coagulation, and decrease in haematocrit. None of the patients developed compartment syndrome or required surgical debridement. The majority of the patients with snakebites of fingers or toes by Vipera ammodytes can be treated conservatively. Surgery is indicated only in case of compartment syndrome, where fasciotomies should be performed without delay after diagnosis.

    InvA, which is essential for Salmonella spp. to enter cultured epithelial cells, is a member of a family of proteins involved in either flagellar biosynthesis or the secretion of virulence determinants by a number of plant and mammalian pathogens. The predicted overall secondary structures of these proteins show significant similarities and indicate a modular construction with a hydrophobic amino-terminal half, consisting of six to eight potential transmembrane domains, and a hydrophilic carboxy terminus which is predicted to reside in the cytoplasm. These proteins can be aligned over the entire length of their polypeptide sequences, with the highest degree of homology found in the amino terminus and clusters of conserved residues in the carboxy terminus. We examined the functional conservation among members of this protein family by assessing the ability of MxiA of Shigella flexneri and LcrD of Yersinia pseudotuberculosis to restore invasiveness to an invA mutant of Salmonella typhimurium. We found that MxiA was able to complement the entry defect of the invA mutant strain of S. typhimurium. In contrast, LcrD failed to complement the same strain. However, a plasmid carrying a gene encoding a chimeric protein consisting of the amino terminus of LcrD and the carboxy terminus of InvA complemented the defect of the Salmonella invA mutant. These results indicate that the secretory systems in which these proteins participate are functionally similar and that the Salmonella and Shigella systems are very closely related. These data also suggest that determinants of specificity may be located at the carboxy termini of these proteins.

  4. Oncogenic intra-p53 family member interactions in human cancers

    Full Text Available The p53 gene family members p53, p73 and p63 display several isoforms derived from the presence of internal promoters and alternative splicing events. They are structural homologues but hold peculiar functional properties. p53, p73 and p63 are tumor suppressor genes that promote differentiation, senescence and apoptosis. p53, unlike p73 and p63, is frequently mutated in cancer often displaying oncogenic gain of function (GOF activities correlated with the induction of proliferation, invasion, chemoresistance and genomic instability in cancer cells. These oncogenic functions are promoted either by the aberrant transcriptional cooperation of mutant p53 (mutp53 with transcription cofactors (e.g., NF-Y, E2F1, Vitamin D Receptor (VDR, Ets-1, NF-kB and YAP or by the interaction with the p53 family members, p73 and p63, determining their functional inactivation. The instauration of these aberrant transcriptional networks leads to increased cell growth, low activation of DNA damage response pathways (DNA damage response (DDR, DNA double-strand breaks (DSBs response, enhanced invasion and high chemoresistance to different conventional chemotherapeutic treatments. Several studies have clearly shown that different cancers harboring mutant p53 proteins exhibit a poor prognosis when compared to those carrying wild type p53 (wt-p53 protein. The interference of mutantp53/p73 and/or mutantp53/p63 interactions, thereby restoring p53, p73 and p63 tumor suppression functions, could be among the potential therapeutic strategies for the treatment of mutant p53 human cancers.

    Highlights: {yields} Impaired trafficking of kAE1 causes distal renal tubular acidosis (dRTA). {yields} The interaction between kAE1 and kinesin family member 3B (KIF3B) is reported. {yields} The co-localization between kAE and KIF3B was detected in human kidney tissues. {yields} A marked reduction of kAE1 on the cell membrane was observed when KIF3B was knockdown. {yields} KFI3B plays an important role in trafficking of kAE1 to the plasma membrane. -- Abstract: Impaired trafficking of human kidney anion exchanger 1 (kAE1) to the basolateral membrane of {alpha}-intercalated cells of the kidney collecting duct leads to the defect of the Cl{sup -}/HCO{sub 3}{sup -} exchange and the failure of proton (H{sup +}) secretion at the apical membrane of these cells, causing distal renal tubular acidosis (dRTA). In the sorting process, kAE1 interacts with AP-1 mu1A, a subunit of AP-1A adaptor complex. However, it is not known whether kAE1 interacts with motor proteins in its trafficking process to the plasma membrane or not. We report here that kAE1 interacts with kinesin family member 3B (KIF3B) in kidney cells and a dileucine motif at the carboxyl terminus of kAE1 contributes to this interaction. We have also demonstrated that kAE1 co-localizes with KIF3B in human kidney tissues and the suppression of endogenous KIF3B in HEK293T cells by small interfering RNA (siRNA) decreases membrane localization of kAE1 but increases its intracellular accumulation. All results suggest that KIF3B is involved in the trafficking of kAE1 to the plasma membrane of human kidney {alpha}-intercalated cells.

    Laccases (benzenediol:oxygen oxidoreductases, EC 1.10.3.2) are blue multicopper oxidases, catalyzing the oxidation of an array of aromatic substrates concomitantly with the reduction of molecular oxygen to water. Most of the known laccases have fungal or plant origins, although few laccases have been also identified in bacteria and insects. Most of the fungal laccases reported thus far are extra-cellular enzymes, whereas only few enzymes from fruiting bodies have been described so far. Multiple isoforms of laccases are usually secreted by each fungus depending on species and environmental conditions. As a fact, a laccase gene family has been demonstrated in the white-rot fungus Pleurotus ostreatus. This work allowed identification and characterization of the first laccase isoenzyme from the fruiting body of P. ostreatus. Discovery through mass spectrometry of LACC12 proves the expression of a functional protein by the related deduced encoding transcript. The topology of phylogenetic tree of fungal laccases proves that LACC12 falls in cluster with the members of P. ostreatus LACC10 (=POXC) subfamily, although lacc12 deduced intron-exon structure differs from that of the subfamily members and the related locus is located in a different chromosome. Results show that the evolutionary pattern of lacc12 and that of the other laccase isozyme genes may have evolved independently, possibly through duplication-divergence events. The reported data add a new piece to the knowledge about P. ostreatus laccase multigene family and shed light on the role(s) played by individual laccase isoforms in P. ostreatus.

    Polymorphic light eruption (PLE) is described as a delayed-type hypersensitivity reaction (DTHR) toward a de novo light-induced antigen, yet to be identified. In effect, the inflammatory pathways of PLE and allergic contact dermatitis (ACD) share common patterns in terms of the mediators involved from the innate and adaptive immune system participating in the DTHR. As we have previously highlighted the role of interleukin (IL)-1 family members in ACD, we hypothesised that the same mediators could have similar functions in PLE. Our research aimed to assess the expression of certain IL-1family members in PLE patients vs. controls, and to compare it with ACD. The study population comprised 17 patients with PLE, 5 affected by ACD and 10 healthy controls in the same age range. Lesional and healthy skin samples were collected respectively from patients and donors. IL-36α, IL-36β, IL-36γ, IL-36 receptor antagonist (Ra), IL-1β, IL-33 gene and protein expressions were evaluated through RT-PCR and immunohistochemistry. Circulating proteins in the PLE patients were analysed by using western blot. The IL-36γ gene expression was significantly increased in PLE lesions compared to that in healthy controls and ACD lesions (***p PLE lesions compared to those of the healthy samples (***p PLE patients vs. controls (*p PLE with distinct differences from those in ACD, in particular with regard to IL-36γ mRNA regulation. Their role as activators of the local, and perhaps systemic, immune response, or as inhibitors of the immune tolerance machinery, needs further investigation.

    To explore family members' experiences when their loved one is undergoing chemotherapy treatment as an outpatient for newly diagnosed colorectal cancer and to develop an explanatory theory of how they process their main concern. Most individuals with cancer are now treated as outpatients and cared for by family members. International research highlights the many side effects of chemotherapy, which in the absence of specific information and/or experience can be difficult for family members to deal with. Unmet needs can have an impact on the health of both patients and family members. Classic grounded theory methodology was used for this study. Using classic grounded theory methodology, family members (n = 35) of patients undergoing chemotherapy treatment for cancer were interviewed (June 2010-July 2011). Data were analysed using the concurrent processes of constant comparative analysis, data collection, theoretical sampling and memo writing. The main concern that emerged for participants was fear of emotional collapse. This fear was dealt with through a process conceptualized as 'Emotional Resistance Building'. This is a basic social process with three phases: 'Figuring out', 'Getting on with it' and 'Uncertainty adjustment'. The phases are not linear, but interrelated as participants can be in any one or more of the phases at any one time. This theory has the potential to be used by healthcare professionals working in oncology to support family members of patients undergoing chemotherapy. New ways of supporting family members through this most difficult and challenging period are articulated within this theory. © 2014 John Wiley & Sons Ltd.

    Adherence to positive airway pressure (PAP) therapy for obstructive sleep apnea (OSA) remains a challenge in children. We hypothesized that the presence of another family member on PAP therapy (parent, sibling, other family member) would be associated with better adherence in the child. We conducted a retrospective chart review to identify children family member on PAP therapy, patient demographics, and clinical characteristics. Group differences between children with and without a family member on PAP therapy were determined using χ(2) test and Wilcoxon two-sample test. PAP adherence measures at each time point and patterns of change across time between the two groups were examined using mixed-effects models. The final analytic sample included 56 children: age 13.2 ± 3.7 years, 60% male, 67% African American, 65% obese, and 32% with developmental disabilities. The mean obstructive apnea-hypopnea index was 25.2 ± 28.7, and 19 (33%) had a family member on PAP therapy. Overall PAP adherence was 2.8 ± 2.4 h/night at 3 months. At month 3, the group with a family member on PAP therapy had significantly greater average nightly PAP use on all nights (3.6 ± 0.6 vs. 2.3 ± 0.39) and on nights used (4.8 ± 0.6 vs. 3.8 ± 0.40); (p value = 0.04). Overall PAP adherence was low, but having a family member on PAP therapy as a "role model" was associated with better adherence.

    Sodium reduction is very important in preventing cardiovascular diseases, especially in regions with high salt intake such as Japan. One strategy for salt reduction is to raise consumer awareness of the need to reduce daily salt intake. We investigated whether cooking classes given to housewives focussing on salt reduction would influence not only their own consumption behaviour but also that of their family members. Single-blinded, cluster randomized trial. We randomly assigned housewives to participate in cooking classes focussing on salt reduction (intervention group) or lectures about a healthy lifestyle (control group). The main outcome measure was the difference in estimated daily salt intake by spot urine sampling of housewives and their family members 2 months after intervention between the groups. A total of 35 housewives and 33 family members were randomized. The mean daily salt intake was 10.00 (standard deviation [SD] 1.75) g/day in the control group (17 housewives and 15 family members) and 9.57 (SD 2.45) g/day in the intervention group (18 housewives and 18 family members) at baseline. Two months after the intervention, the mean salt intake was 10.30 (SD 1.78) g/day in the control group and 8.95 (SD 2.45) g/day in the intervention group. The mean difference was -1.19 g/day (95% confidence interval -2.29, -0.09; P = 0.034). A similar tendency was observed in the subgroups of housewives and family members. Our trial suggested that the effects of cooking classes focussing on salt reduction for housewives could be transferred to family members (UMIN-CTR: 000018870).

    The family of resistin-like molecules (RELM), also known as found in inflammatory zone (FIZZ), consists of four members in mouse (RELMα/FIZZ1/HIMF, RELMβ/FIZZ2, Resistin/FIZZ3, and RELMγ/FIZZ4) and two members in human (resistin and RELMβ). The importance of these proteins in many aspects of physiology and pathophysiology, especially inflammatory processes, is rapidly evolving in the literature, and many investigators are beginning to work in this field. Most published studies focus on only one isoform, do not evaluate other isoforms that might be present, and have not tested for the specificity of the antibody used. Because RELM isoforms have high sequence and structural similarity and both distinct and overlapping functions, it is important to use a specific antibody to distinguish each isoform in the study. We constructed and established HEK 293 cell lines that constitutively express each isoform. Using these cell lines, we determined the specificity of antibodies (both commercially available and laboratory-made) to each isoform by Western blot and immunofluorescence. Some of the antibodies showed specificity in Western blotting but were not applicable in immunofluorescence. Others showed cross reactivity in Western blot assays. Our results indicate that RELM antibody specificity should be taken into account when using them in research and interpreting data obtained with them.

MttB is the only known trimethylamine methyltransferase, yet the great majority of members of COG5598 lack pyrrolysine, leaving the activity of these proteins an open question. Here, we describe the function of one of the nonpyrrolysine members of this large protein family. Three nonpyrrolysine MttB homologs are encoded in Desulfitobacterium hafniense, a Gram-positive strict anaerobe present in both the environment and human intestine. D. hafniense was found capable of growth on glycine betaine with electron acceptors such as nitrate or fumarate, producing dimethylglycine and CO2 as products. Examination of the genome revealed genes for tetrahydrofolate-linked oxidation of a methyl group originating from a methylated corrinoid protein, but no obvious means to carry out corrinoid methylation with glycine betaine. DSY3156, encoding one of the nonpyrrolysine MttB homologs, was up-regulated during growth on glycine betaine. The recombinant DSY3156 protein converts glycine betaine and cob(I)alamin to dimethylglycine and methylcobalamin. To our knowledge, DSY3156 is the first glycine betaine:corrinoid methyltransferase described, and a designation of MtgB is proposed. In addition, DSY3157, an adjacently encoded protein, was shown to be a methylcobalamin:tetrahydrofolate methyltransferase and is designated MtgA. Homologs of MtgB are widely distributed, especially in marine bacterioplankton and nitrogen-fixing plant symbionts. They are also found in multiple members of the human microbiome, and may play a beneficial role in trimethylamine homeostasis, which in recent years has been directly tied to human cardiovascular health.

    Full Text Available Auxin response factors (ARFs can function as transcriptional activators or repressors to regulate the expression of auxin response genes by specifically binding to auxin response elements (AuxREs during plant development. Based on a genome-wide strategy using the medicinal model plant Salvia miltiorrhiza, 25 S. miltiorrhiza ARF (SmARF gene family members in four classes (class Ia, IIa, IIb and III were comprehensively analyzed to identify characteristics including gene structures, conserved domains, phylogenetic relationships and expression patterns. In a hybrid analysis of the phylogenetic tree, microRNA targets, and expression patterns of SmARFs in different organs, root tissues, and methyl jasmonate or indole-3-acetic acid treatment conditions, we screened for candidate SmARFs involved in various developmental processes of S. miltiorrhiza. Based on this analysis, we predicted that SmARF25, SmARF7, SmARF16 and SmARF20 are involved in flower, leaf, stem and root development, respectively. With the further insight into the targets of miR160 and miR167, specific SmARF genes in S. miltiorrhiza might encode products that participate in biological processes as described for ARF genes in Arabidopsis. Our results provide a foundation for understanding the molecular basis and regulatory mechanisms of SmARFs in S. miltiorrhiza.

    Borderline personality disorder (BPD) is challenging for family members who are often required to fulfil multiple roles such as those of advocate, caregiver, coach and guardian. To date, two uncontrolled studies by the treatment developers suggest that Family Connections (FC) is an effective programme to support, educate and teach skills to family members of individuals with BPD. However, such studies have been limited by lack of comparison to other treatment approaches. This study aimed to compare the effectiveness of FC with an optimised treatment-as-usual (OTAU) programme for family members of individuals with BPD. A secondary aim was to introduce a long term follow-up to investigate if positive gains from the intervention would be maintained following programme completion.

    Heat shock proteins (Hsps) are involved in a variety of critical biological functions, including protein folding, degradation, and translocation and macromolecule assembly, act as molecular chaperones during periods of stress by binding to other proteins. Using expressed sequence tag (EST) and silkworm (Bombyx mori) transcriptome databases, we identified 27 cDNA sequences encoding the conserved J domain, which is found in DnaJ-type Hsps. Of the 27 J domain-containing sequences, 25 were complete cDNA sequences. We divided them into three types according to the number and presence of conserved domains. By analyzing the gene structures, intron numbers, and conserved domains and constructing a phylogenetic tree, we found that the DnaJ family had undergone convergent evolution, obtaining new domains to expand the diversity of its family members. The acquisition of the new DnaJ domains most likely occurred prior to the evolutionary divergence of prokaryotes and eukaryotes. The expression of DnaJ genes in the silkworm was generally higher in the fat body. The tissue distribution of DnaJ1 proteins was detected by western blotting, demonstrating that in the fifth-instar larvae, the DnaJ1 proteins were expressed at their highest levels in hemocytes, followed by the fat body and head. We also found that the DnaJ1 transcripts were likely differentially translated in different tissues. Using immunofluorescence cytochemistry, we revealed that in the blood cells, DnaJ1 was mainly localized in the cytoplasm.

    The mammalian endoplasmic reticulum (ER) harbors disulfide bond-generating enzymes, including Ero1α and peroxiredoxin 4 (Prx4), and nearly 20 members of the protein disulfide isomerase family (PDIs), which together constitute a suitable environment for oxidative protein folding. Here, we clarified the Prx4 preferential recognition of two PDI family proteins, P5 and ERp46, and the mode of interaction between Prx4 and P5 thioredoxin domain. Detailed analyses of oxidative folding catalyzed by the reconstituted Prx4-PDIs pathways demonstrated that, while P5 and ERp46 are dedicated to rapid, but promiscuous, disulfide introduction, PDI is an efficient proofreader of non-native disulfides. Remarkably, the Prx4-dependent formation of native disulfide bonds was accelerated when PDI was combined with ERp46 or P5, suggesting that PDIs work synergistically to increase the rate and fidelity of oxidative protein folding. Thus, the mammalian ER seems to contain highly systematized oxidative networks for the efficient production of large quantities of secretory proteins.

    Using a modified cDNA representational difference analysis (RDA) method, a LEA gene fragment was isolated from the regulated carrot somatic embryo, which was used as the probe to screen the cDNA library of the regulated carrot somatic embryo and the genomic library constructed by the method of altering osmotic pressure. Sequence analysis showed that it is homologous to LEA gene family and designated as DcLEA1 (GenBank number: AF308739), a new member of the carrot LEA gene family. Its transcription region contains 5′ UTR, two exons, one intron and 3′ UTR region; its coding region is 480 bp long, coding for 159 amino acids and one stop codon. Northern hybridization indicated that DcLEA1 gene was not expressed in the adult carrot but expressed at high levels in the regulated carrot somatic embryo. In carrot somatic embryo which had been deregulated for 12 hours, the expression levels dropped rapidly; with the prolongation of deregulation, the radicle of carrot somatic embryo began to stretch, and the expression level of DcLEA1 gene increased. This phenomenon is similar to the expression pattern of LEA gene in the course of dormancy and germination of the seed; thus suggesting that the sucrose regulation-deregulation system of the carrot somatic embryo can be used to mimic plant seed dormancy and germination and can also be used to study the molecular mechanisms of these two biological processes.

    Full Text Available Abstract: The Enterobacteriaceae family contains potentially zoonotic bacteria, and their presence in canaries is often reported, though the current status of these in bird flocks is unknown. Therefore, this study aimed to identify the most common genera of enterobacteria from canaries (Serinus canaria and their antimicrobial resistance profiles. From February to June of 2013, a total of 387 cloacal swab samples from eight domiciliary breeding locations of Fortaleza city, Brazil, were collected and 58 necropsies were performed in canaries, which belonged to the Laboratory of Ornithological Studies. The samples were submitted to microbiological procedure using buffered peptone water and MacConkey agar. Colonies were selected according to their morphological characteristics on selective agar and submitted for biochemical identification and antimicrobial susceptibility. A total of 61 isolates were obtained, of which 42 were from cloacal swabs and 19 from necropsies. The most isolated bacteria was Escherichia coli with twenty five strains, followed by fourteen Klebsiellaspp., twelve Enterobacterspp., seven Pantoea agglomerans, two Serratiaspp. and one Proteus mirabilis. The antimicrobial to which the strains presented most resistance was sulfonamides with 55.7%, followed by ampicillin with 54.1% and tetracycline with 39.3%. The total of multidrug-resistant bacteria (MDR was 34 (55.7%. In conclusion, canaries harbor members of the Enterobacteriaceae family and common strains present a high antimicrobial resistance rate, with a high frequency of MDR bacteria.

When comparative studies of family businesses begin to surface on the family involvement in business, there is that irritating question on what effect is brought about by family involvement to the business. Therefore, the purpose of this study is to explore business advantages and disadvantages generated by family involvement in...

  1. P53 family members modulate the expression of PRODH, but not PRODH2, via intronic p53 response elements.

    Directory of Open Access Journals (Sweden)

    Ivan Raimondi

    Full Text Available The tumor suppressor p53 was previously shown to markedly up-regulate the expression of the PRODH gene, encoding the proline dehydrogenase (PRODH enzyme, which catalyzes the first step in proline degradation. Also PRODH2, which degrades 4-hydroxy-L-proline, a product of protein (e.g. collagen catabolism, was recently described as a p53 target. Here, we confirmed p53-dependent induction of endogenous PRODH in response to genotoxic damage in cell lines of different histological origin. We established that over-expression of TAp73β or TAp63β is sufficient to induce PRODH expression in p53-null cells and that PRODH expression parallels the modulation of endogenous p73 by genotoxic drugs in several cell lines. The p53, p63, and p73-dependent transcriptional activation was linked to specific intronic response elements (REs, among those predicted by bioinformatics tools and experimentally validated by a yeast-based transactivation assay. p53 occupancy measurements were validated in HCT116 and MCF7 human cell lines. Conversely, PRODH2 was not responsive to p63 nor p73 and, at best, could be considered a weak p53 target. In fact, minimal levels of PRODH2 transcript induction by genotoxic stress was observed exclusively in one of four p53 wild-type cell lines tested. Consistently, all predicted p53 REs in PRODH2 were poor matches to the p53 RE consensus and showed very weak responsiveness, only to p53, in the functional assay. Taken together, our results highlight that PRODH, but not PRODH2, expression is under the control of p53 family members, specifically p53 and p73. This supports a deeper link between proteins of the p53-family and metabolic pathways, as PRODH modulates the balance of proline and glutamate levels and those of their derivative alpha-keto-glutarate (α-KG under normal and pathological (tumor conditions.

    To investigate the intentions of nurses and nursing students to telling the truth to patients and families, based on the Theory of Planned Behavior which examines intention to perform behaviours. In recent decades, the perception that patients have a moral and legal right to truthful and reliable information has become dominant. However, the study of telling the truth to non-oncology patients has received scant attention and little is known about the intention of nurses and nursing students to tell the truth. A cross-sectional design. We used a scenario-based questionnaire, illustrating eight different situations in which nurses/nursing students are asked to tell the truth to a patient or family member regarding a devastating disease with which the patient is afflicted. Data were analysed using the Mann-Whitney U-test and ridge regression. The sample included 150 participants, 110 registered nurses and 40 third year nursing students, with a response rate of 87%. The results show that nurses and nursing students intend to tell the whole truth even if this is not easy for them. Nurses more than students think that it is important to tell the whole truth and intend to do so. Head nurses tend to tell the truth more than staff nurses. For nurses, the components of the Theory of Planned Behaviour predicted intention to tell the truth, whereas among students subjective norms were the only predictor of intention. The Theory of Planned Behaviour is a powerful predictor of nurse intention to tell the whole truth to patients and their families. Students perceive social pressure as the most important incentive of their intention to tell the truth. Nurses and nursing students should receive additional training in dealing with various situations involving truth telling. © 2012 Blackwell Publishing Ltd.

    The aim of the study was to find out how nursing home residents, their families and nurses experienced the change to primary nursing in the nursing home. This study was carried out in a nursing home in Finland. Following years of functional nursing, the change to primary nursing had started 18 months prior to data collection. The transition was preceded by staff training, planning for the change to primary nursing and discussions with staff members. Meetings were also arranged with family members to inform them of what was happening and why. Staff implemented the changeover independently with the support of the institution's management. The data were gathered in focused interviews. There were five interview themes: change in the nursing home, the position of the resident in the nursing home, the relationship between the resident and nurse, the relationship between family member and nurse, and the role of the nurse as provider of nursing care. Residents reported no major changes in nursing care or in their relationship with nurses. However, family members had noticed changes in the behaviour of the nursing staff. Staff members had become friendlier, spent more time with the residents and showed a strong job motivation. Cooperation between nurses and family members had changed very little. Some nurses in the early stages of the change tended to show signs of resistance. Others said that there had been many changes during the past year, that they acted more independently and could use their own decision-making authority more freely than before. They treated residents as individuals and gave them a greater say in decision-making. They felt responsible for the development of the workplace as a collectivity. Primary nursing is one way in which nurses and family members can work more closely in the best interests of older residents. The findings of this study speak in favour of making the change from functional to primary nursing and at the same time highlight certain

    Classical nuclear localization signal (NLS) dependent nuclear import is carried out by a heterodimer of importin alpha and importin beta. NLS cargo is recognized by importin alpha, which is bound by importin beta. Importin beta mediates translocation of the complex through the central channel of the nuclear pore, and upon reaching the nucleus, RanGTP binding to importin beta triggers disassembly of the complex. To date, six importin alpha family members, encoded by separate genes, have been described in humans. We sequenced and characterized a seventh member of the importin alpha family of transport factors, karyopherin alpha 7 (KPNA7), which is most closely related to KPNA2. The domain of KPNA7 that binds Importin beta (IBB) is divergent, and shows stronger binding to importin beta than the IBB domains from of other importin alpha family members. With regard to NLS recognition, KPNA7 binds to the retinoblastoma (RB) NLS to a similar degree as KPNA2, but it fails to bind the SV40-NLS and the human nucleoplasmin (NPM) NLS. KPNA7 shows a predominantly nuclear distribution under steady state conditions, which contrasts with KPNA2 which is primarily cytoplasmic. KPNA7 is a novel importin alpha family member in humans that belongs to the importin alpha2 subfamily. KPNA7 shows different subcellular localization and NLS binding characteristics compared to other members of the importin alpha family. These properties suggest that KPNA7 could be specialized for interactions with select NLS-containing proteins, potentially impacting developmental regulation.

    This article presents emerging findings from the first year of a two-year study, which employed ethnographic methods to explore the culture of interprofessional collaboration (IPC) and family member involvement in eight North American intensive care units (ICUs). The study utilized a comparative ethnographic approach - gathering observation, interview and documentary data relating to the behaviors and attitudes of healthcare providers and family members across several sites. In total, 504 hours of ICU-based observational data were gathered over a 12-month period in four ICUs based in two US cities. In addition, 56 semi-structured interviews were undertaken with a range of ICU staff (e.g. nurses, doctors and pharmacists) and family members. Documentary data (e.g. clinical guidelines and unit policies) were also collected to help develop an insight into how the different sites engaged organizationally with IPC and family member involvement. Directed content analysis enabled the identification and categorization of major themes within the data. An interprofessional conceptual framework was utilized to help frame the coding for the analysis. The preliminary findings presented in this paper illuminate a number of issues related to the nature of IPC and family member involvement within an ICU context. These findings are discussed in relation to the wider interprofessional and health services literature.

    Crying has not been studied from the perspective of family members of patients in palliative care. The aim of this study was to explore the significance of family members crying in a palliative care context with special reference to factors that influence crying. Interviews were carried out with 14 family members of patients admitted to palliative care. A hermeneutic approach according to Gadamer was used. Three main categories emerged. (1) Before the start of crying, some prerequisites for crying had to be fulfilled, such as an allowing attitude and courage, time, feeling secure, honesty, and trusting relationships. These prerequisites did not cause crying themselves; rather crying emerged when triggering factors occurred. (2) Triggers for crying were circumstances that created uncertainty and turbulence (bad news), exhaustion due to lack of own time, and sympathy from others. (3) Family members tried to do the best possible by adopting or hiding their crying, to ease the patient's burden and to create a positive counterbalance to suffering and grief. As an interpretation of the whole, crying could be expressed as being shared with someone for support and consolation or escape to solitude for integrity and respite. As a conclusion, crying may be an efficient strategy for family members in palliative care to express their suffering and to gain new energy to continue.

    Mono-ADP-ribosylation is one of the posttranslational protein modifications regulating cellular metabolism, e.g., nitrogen fixation, in prokaryotes. Several bacterial toxins mono-ADP-ribosylate and inactivate specific proteins in their animal hosts. Recently, two mammalian GPI-anchored cell surface enzymes with similar activities were cloned (designated ART1 and ART2). We have now identified six related expressed sequence tags (ESTs) in the public database and cloned the two novel human genes from which these are derived (designated ART3 and ART4). The deduced amino acid sequences of the predicted gene products show 28% sequence identity to one another and 32-41% identity vs the muscle and T cell enzymes. They contain signal peptide sequences characteristic of GPI anchorage. Southern Zoo blot analyses suggest the presence of related genes in other mammalian species. By PCR screening of somatic cell hybrids and by in situ hybridization, we have mapped the two genes to human chromosomes 4p14-p15.l and 12q13.2- q13.3. Northern blot analyses show that these genes are specifically expressed in testis and spleen, respectively. Comparison of genomic and cDNA sequences reveals a conserved exon/intron structure, with an unusually large exon encoding the predicted mature membrane proteins. Secondary structure prediction analyses indicate conserved motifs and amino acid residues consistent with a common ancestry of this emerging mammalian enzyme family and bacterial mono(ADP-ribosyl)transferases. It is possible that the four human gene family members identified so far represent the {open_quotes}tip of an iceberg,{close_quote} i.e., a larger family of enzymes that influences the function of target proteins via mono-ADP-ribosylation. 35 refs., 4 figs.

    MicroRNAs (miRNAs) are a class of endogenous small RNAs that play important regulatory roles in both animals and plants, miRNA genes have been intensively studied in animals, but not in plants. In this study, we adopted a homology search approach to identify homologs of previously validated plant miRNAs in Arabidopsis thaliana and Oryza sativa. We identified 20 potential miRNA genes in Arabidopsis and 40 in O. sativa, providing a relatively complete enumeration of family members for these miRNAs in plants. In addition, a greater number ofArabidopsis miRNAs (MIR168, MIR159 and MIR172) were found to be conserved in rice. With the novel homologs, most of the miRNAs have closely related fellow miRNAs and the number of paralogs varies in the different miRNA families. Moreover, a probable functional segment highly conserved on the elongated stem of pre-miRNA fold-backs of MIR319 and MIR 159 family was identified. These results support a model of variegated miRNA regulation in plants, in which miRNAs with different functional elements on their pre-miRNA fold-backs can differ in their function or regulation, and closely related miRNAs can be diverse in their specificity or competence to downregulate target genes. It appears that the sophisticated regulation of miRNAs can achieve complex biological effects through qualitative and quantitative modulation of gene expression profiles in plants.

    Full Text Available This study aimed to understand the concepts of family members of patients with cancer, who were inserted and guided by the actions of an extension project aimed at patients with cancer and their families, about the home care given to them, during the treatment phase and progression of the disease. This is an evaluative qualitative research conducted with six family members from June to October, 2013, through semi-structured interviews, analyzed by the method of content analysis. Three categories emerged: the support of nurses in coping with the disease, creating a bond with the patients and their families and nursing as a link to social support networks. It was understood that the health monitoring in the home context gave to the families and patients support and safety to handle concerns that cancer brought into their lives.

    The positive effect of family support on the outcome from serious illness that requires intensive care has been recognized by clinicians for decades. We have all seen that family visitation and an intensive care environment more similar to that of a general ward (sunlight, radio, television) can benefit patients with psychosis related to intensive care. The severity of illness of the individual patient exerts a powerful stress on the family unit, but it has been difficult to measure this effect. We used a 40-question family needs survey with a degree of importance scale to compare the intensive care unit (ICU) with the general ward in terms of impact on the family. Five needs were found to discriminate these two environments. The family members of patients in an ICU considered it very important (1) for staff to give directions on what to do at the bedside, (2) to receive more support from their own family unit, (3) to have a place to be alone as a family unit in the hospital, (4) to be informed in advance of any transfer plan, and (5) to have flexibility in the time allowed for visitation. Family members are willing to accept decreased visitation time if the physicians and nurses can equate this decrease with the complexity of care in the ICU. The results of this survey have helped us modify and individualize our approach based on family expectations especially when patients are transferred from the general ward to the ICU or from the ICU to the ward.

    Social workers in substance abuse treatment settings are responsible for involving families in treatment program to improve family functioning. The effectiveness of available interventions in treating codependency of family members of drug users in Iran is not well explored. We evaluated the effectiveness of the Satir communication family therapy (CFT) in healing codependency of drug dependents' family members in Tehran, Iran. The intervention group participants (n = 27) received a seven-session social work intervention with CFT approach and the control group (n = 26) received treatment as usual. We used the Holyoake Codependency Index to measure participants' codependency at baselines, end of intervention, and 90 days post intervention. Codependents enrolled in the intervention had a significantly lower codependency score than controls at the end of intervention and 90 days post intervention. CFT is an effective strategy to reduce codependency in Iranian population and can be explored as a population-based strategy.

    As European Member States are making progress towards their 2020 targets in the Effort Sharing Decision, the attention of policymakers is shifting to a framework beyond 2020. The European Commission launched a discussion with its Green Paper on a possible policy framework for 2030. This PBL Note aims to contribute to that discussion by analysing the effects of various assumptions on Member States' non-ETS emission targets for 2030. The effort sharing of the current European target for 2020 has resulted in an emission target of +20% relative to 2005 levels for the least wealthy Member State and -20% for the three wealthiest Member States. The targets for all other Member States were determined based on per-capita income levels of 2005. For possible non-ETS targets for 2030, we assumed a Europe-wide emission reduction target of 40% for 2030, compared to 1990 levels. This target is considered by the European Commission as the most cost-efficient to achieve a low-carbon economy by 2050. The 2030 target was split into a target for emissions covered by the EU Emissions Trading System (ETS) and one for emissions that are not covered by the ETS (non-ETS). According to our estimations, European non-ETS emissions need to be reduced by around 30% by 2030, compared to 2005 levels. We distributed the non-ETS reduction target of 30% over the Member States by using similar effort sharing principles that are applied in the EU Effort Sharing Decision for 2020, but with different targets assumed for the least wealthy Member State. We also took recent per-capita income levels into account. However, we did not take into account the costs and effects of emission reductions on GDP. This PBL Note analyses two possible scenarios that differ in the target assumed for the least wealthy Member State, in order to assess the effects of differing assumptions on the 2030 non-ETS targets. These scenarios should be considered as 'what if' scenarios and not as political positions

  13. Youth’s narratives about family members smoking: parenting the parent- it’s not fair!

    Science.gov (United States)

    2012-01-01

    Background Successful cancer prevention policies and programming for youth must be based on a solid understanding of youth’s conceptualization of cancer and cancer prevention. Accordingly, a qualitative study examining youth’s perspectives of cancer and its prevention was undertaken. Not surprisingly, smoking (i.e., tobacco cigarette smoking) was one of the dominant lines of discourse in the youth’s narratives. This paper reports findings of how youth conceptualize smoking with attention to their perspectives on parental and family-related smoking issues and experiences. Methods Seventy-five Canadian youth ranging in age from 11–19 years participated in the study. Six of the 75 youth had a history of smoking and 29 had parents with a history of smoking. Youth were involved in traditional ethnographic methods of interviewing and photovoice. Data analysis involved multiple levels of analysis congruent with ethnography. Results Youth’s perspectives of parents and other family members’ cigarette smoking around them was salient as represented by the theme: It’s not fair. Youth struggled to make sense of why parents would smoke around their children and perceived their smoking as an unjust act. The theme was supported by four subthemes: 1) parenting the parent about the dangers of smoking; 2) the good/bad parent; 3) distancing family relationships; and 4) the prisoner. Instead of being talked to about smoking it was more common for youth to share stories of talking to their parents about the dangers of smoking.

    Full Text Available Abstract Background Successful cancer prevention policies and programming for youth must be based on a solid understanding of youth’s conceptualization of cancer and cancer prevention. Accordingly, a qualitative study examining youth’s perspectives of cancer and its prevention was undertaken. Not surprisingly, smoking (i.e., tobacco cigarette smoking was one of the dominant lines of discourse in the youth’s narratives. This paper reports findings of how youth conceptualize smoking with attention to their perspectives on parental and family-related smoking issues and experiences. Methods Seventy-five Canadian youth ranging in age from 11–19 years participated in the study. Six of the 75 youth had a history of smoking and 29 had parents with a history of smoking. Youth were involved in traditional ethnographic methods of interviewing and photovoice. Data analysis involved multiple levels of analysis congruent with ethnography. Results Youth’s perspectives of parents and other family members’ cigarette smoking around them was salient as represented by the theme: It’s not fair. Youth struggled to make sense of why parents would smoke around their children and perceived their smoking as an unjust act. The theme was supported by four subthemes: 1 parenting the parent about the dangers of smoking; 2 the good/bad parent; 3 distancing family relationships; and 4 the prisoner. Instead of being talked to about smoking it was more common for youth to share stories of talking to their parents about the dangers of smoking. Parents who did not smoke were seen by youth as the good parent, as opposed to the bad parent who smoked. Smoking was an agent that altered relationships with parents and other family members. Youth who lived in homes where they were exposed to cigarette smoke felt like a trapped prisoner. Conclusions Further research is needed to investigate youth’s perceptions about parental cigarette smoking as well as possible linkages

    8000 cases of renal cancer are diagnosed each year in the UK, with a five-year survival rate of 50%. Treatment options are limited; a potential therapeutic target is the Src family kinases (SFKs). SFKs have roles in multiple oncogenic processes and promote metastases in solid tumours. The aim of this study was to investigate SFKs as potential therapeutic targets for clear cell renal cell carcinoma (ccRCC). SFKs expression was assessed in a tissue microarray consisting of 192 ccRCC patients with full clinical follow-up. SFK inhibitors, dasatinib and saracatinib, were assessed in early ccRCC cell lines, 786-O and 769-P and a metastatic ccRCC cell line, ACHN (± Src) for effects on protein expression, apoptosis, proliferation and wound healing. High nuclear expression of Lyn and the downstream marker of activation, paxillin, were associated with decreased patient survival. Conversely, high cytoplasmic expression of other SFK members and downstream marker of activation, focal adhesion kinase (FAK) were associated with increased patient survival. Treatment of non-metastatic 786-O and 769-P cells with dasatinib, dose dependently reduced SFK activation, shown via SFK (Y(419)) and FAK (Y(861)) phosphorylation, with no effect in metastatic ACHN cells. Dasatinib also increased apoptosis, while decreasing proliferation and migration in 786-O and 769-P cell lines, both in the presence and absence of Src protein. Our data suggests that nuclear Lyn is a potential therapeutic target for ccRCC and dasatinib affects cellular functions associated with cancer progression via a Src kinase independent mechanism.

    Pleomorphic adenoma gene (PLAG) 1, the main translocation target in pleomorphic adenomas of the salivary glands, is a member of a new subfamily of zinc finger proteins comprising the tumor suppressor candidate PLAG-like1 (also called ZAC1 or lost on transformation 1) and PLAGL2. In this report, we show that NIH3T3 cells overexpressing PLAG1 or PLAGL2 display the typical markers of neoplastic transformation: (a) the cells lose cell-cell contact inhibition; (b) show anchorage-independent growth; and (c) are able to induce tumors in nude mice. In contrast, PLAGL1 has been shown to prevent the proliferation of tumor cells by inducing cell cycle arrest and apoptosis. This difference in function is also reflected in their DNA binding, as we show here that the three PLAG proteins, although highly homologous in their DNA-binding domain, bind different DNA sequences in a distinct fashion. Interestingly, the PLAG1- and PLAGL2-induced transformation is accompanied by a drastic up-regulation of insulin-like growth factor-II, which we prove is a target of PLAG1 and PLAGL2. This strongly suggests that the oncogenic capacity of PLAG1 and PLAGL2 is mediated at least partly by activating the insulin-like growth factor-II mitogenic pathway.

    The aim of this study is to examine family members' experiences of end-of-life decision-making processes in Norwegian intensive care units (ICUs) to ascertain the degree to which they felt included in the decision-making process and whether they received necessary information. Were they asked about the patient's preferences, and how did they view their role as family members in the decision-making process? A constructivist interpretive approach to the grounded theory method of qualitative research was employed with interviews of 27 bereaved family members of former ICU patients 3-12 months after the patient's death. The core finding is that relatives want a more active role in end-of-life decision-making in order to communicate the patient's wishes. However, many consider their role to be unclear, and few study participants experienced shared decision-making. The clinician's expression "wait and see" hides and delays the communication of honest and clear information. When physicians finally address their decision, there is no time for family participation. Our results also indicate that nurses should be more involved in family-physician communication. Families are uncertain whether or how they can participate in the decision-making process. They need unambiguous communication and honest information to be able to take part in the decision-making process. We suggest that clinicians in Norwegian ICUs need more training in the knowledge and skills of effective communication with families of dying patients.

  18. Mth10b, a unique member of the Sac10b family, does not bind nucleic acid.

    Yan-Feng Liu

    Full Text Available The Sac10b protein family is regarded as a group of nucleic acid-binding proteins that are highly conserved and widely distributed within archaea. All reported members of this family are basic proteins that exist as homodimers in solution and bind to DNA and/or RNA without apparent sequence specificity in vitro. Here, we reported a unique member of the family, Mth10b from Methanobacterium thermoautotrophicum ΔH, whose amino acid sequence shares high homology with other Sac10b family proteins. However, unlike those proteins, Mth10b is an acidic protein; its potential isoelectric point is only 4.56, which is inconsistent with the characteristics of a nucleic acid-binding protein. In this study, Mth10b was expressed in Escherichia coli and purified using a three-column chromatography purification procedure. Biochemical characterization indicated that Mth10b should be similar to typical Sac10b family proteins with respect to its secondary and tertiary structure and in its preferred oligomeric forms. However, an electrophoretic mobility shift analysis (EMSA showed that neither DNA nor RNA bound to Mth10b in vitro, indicating that either Mth10b likely has a physiological function that is distinct from those of other Sac10b family members or nucleic acid-binding ability may not be a fundamental factor to the actual function of the Sac10b family.

    Two aerobic, Gram-stain-negative, pale-red-pigmented and rod-shaped bacterial strains, designated SAORIC-26 and SAORIC-28(T), were isolated from seawater (3000 m depth) from the Pacific Ocean. Phylogenetic analysis based on their 16S rRNA gene sequences revealed that the novel isolates could be affiliated with the family Rhodothermaceae of the class Cytophagia. Strains SAORIC-26 and SAORIC-28(T) shared 99.7% pairwise sequence similarity with each other and showed less than 92.6% similarity with other cultivated members of the class Cytophagia. The strains were found to be non-motile, oxidase-positive, catalase-negative and able to hydrolyse gelatin and aesculin. The DNA G+C contents were determined to be 64.8-65.8 mol% and MK-7 was the predominant menaquinone. Summed feature 9 (iso-C17:1ω9c and/or C16:0 10-methyl), summed feature 3 (C16:1ω6c and/or C16:1ω7c) and iso-C15:0 were found to be the major cellular fatty acids. On the basis of this taxonomic study using a polyphasic approach, it was concluded that strains SAORIC-26 and SAORIC-28(T) represent a novel species of a new genus in the family Rhodothermaceae, for which the name Rubrivirga marina gen. nov., sp. nov. is proposed. The type strain of the type species of is SAORIC-28(T) (=KCTC 23867(T)=NBRC 108816(T)). An additional strain of the species is SAORIC-26.

    We report a Caucasian family of two veterinary practitioners and their two children, ages 2 years and 6 months, simultaneously infected with the dermatophyte Trichophyton tonsurans, causing tinea capitis and tinea corporis in the children and tinea corporis in the parents. The parents and older child were successfully treated with oral terbinafine. The infant clinically responded to treatment with topical terbinafine and ketoconazole shampoo but presented with recurrent tinea capitis 12 months later, from which T. tonsurans was cultured. At this time, scalpbrush samples from the other family members failed to culture any fungi, and neither were fungi isolated from the family hairbrushes. The infant then received oral terbinafine, resulting in clinical and mycologic cure. After a further 12 months follow-up, there has been no mycologic evidence of recurrence in any family member.

    Full Text Available This is a qualitative research made from March 2012 to February 2014 to identify and to analyze conceptions and practices of embracement to the family members of the people who use drugs, from the family’s and the professionals’ perspective in a Psychosocial Attention Center specialized in Alcohol and Other Drugs in Maceió, AL, Brazil. Data collection was made by semi-structured interviews with the use of previously elaborated script. Bardin's thematic analysis and discussion approved by Merhy revealed it as an act of receiving. For professionals, it is an administrative reception, triage, and transfer of information. For the family members, it is always to be welcome. The practice, present in relations in which there is the encounter professional-user, materialized in family groups and listening. In the working process, embracement to the families expresses the need of qualified listening, constitution of bond and their co-responsibilities.

  2. Mice lacking the SLAM family member CD84 display unaltered platelet function in hemostasis and thrombosis.

    Directory of Open Access Journals (Sweden)

    Sebastian Hofmann

    Full Text Available BACKGROUND: Platelets are anuclear cell fragments derived from bone marrow megakaryocytes that safeguard vascular integrity by forming thrombi at sites of vascular injury. Although the early events of thrombus formation--platelet adhesion and aggregation--have been intensively studied, less is known about the mechanisms and receptors that stabilize platelet-platelet interactions once a thrombus has formed. One receptor that has been implicated in this process is the signaling lymphocyte activation molecule (SLAM family member CD84, which can undergo homophilic interactions and becomes phosphorylated upon platelet aggregation. OBJECTIVE: The role of CD84 in platelet physiology and thrombus formation was investigated in CD84-deficient mice. METHODS AND RESULTS: We generated CD84-deficient mice and analyzed their platelets in vitro and in vivo. Cd84(-/- platelets exhibited normal activation and aggregation responses to classical platelet agonists. Furthermore, CD84 deficiency did not affect integrin-mediated clot retraction and spreading of activated platelets on fibrinogen. Notably, also the formation of stable three-dimensional thrombi on collagen-coated surfaces under flow ex vivo was unaltered in the blood of Cd84(-/- mice. In vivo, Cd84(-/- mice exhibited unaltered hemostatic function and arterial thrombus formation. CONCLUSION: These results show that CD84 is dispensable for thrombus formation and stabilization, indicating that its deficiency may be functionally compensated by other receptors or that it may be important for platelet functions different from platelet-platelet interactions.

    The pro-apoptotic BH3-only BCL-2 family member BIM is a critical determinant of hematopoietic cell development and homeostasis. It has been argued that the striking hematopoietic abnormalities of BIM-deficient mice (accumulation of lymphocytes and granulocytes) may be the result of the loss of the protein throughout the whole animal rather than a consequence intrinsic to the loss of BIM in hematopoietic cells. To address this issue and allow the deletion of BIM in specific cell types in future studies, we have developed a mouse strain with a conditional Bim allele as well as a new Cre transgenic strain, Vav-CreER, in which the tamoxifen-inducible CreER recombinase (fusion protein) is predominantly expressed in the hematopoietic system. We show that acute loss of BIM in the adult mouse rapidly results in the hematopoietic phenotypes previously observed in mice lacking BIM in all tissues. This includes changes in thymocyte subpopulations, increased white blood cell counts and resistance of lymphocytes to BIM-dependent apoptotic stimuli, such as cytokine deprivation. We have validated this novel conditional Bim knockout mouse model using established and newly developed CreER strains (Rosa26-CreER and Vav-CreER) and will make these exciting new tools for studies on cell death and cancer available.

    Kalilo is a linear 9-kb plasmid, isolated originally from Hawaiian strains of the heterothallic fungus Neurospora intermedia. Its properties include terminal inverted repeats, two ORFs coding for a presumptive DNA and an RNA polymerase, and the ability to cause senescence in its original host and in the closely related species Neurospora crassa. We have examined natural isolates alleged to contain plasmids homologous to kalilo. Most of these isolates do in fact contain plasmids with so close an identity to kalilo as to be certain relatives. We found a new case of kalilo in Neurospora tetrasperma from Moorea-Tahiti, and a new case of LA-kalilo (previously found only in N. tetrasperma) in N. crassa from Haiti. A previously unreported, substantially shorter, kalilo variant has been found in three geographically separate isolates of the heterothallic species Neurospora discreta. Therefore, if the previously reported kalilo variant from the genus Gelasinospora is included, in all there are four members of the kalilo plasmid family. The main differences between these plasmids are in the terminal inverted repeats (TIRs). The phylogeny of the TIR sequences is largely congruent with that of nuclear DNA in the species in which they are found, suggesting that the plasmids are related by vertical descent throughout the evolution of these species. However, there are two cases of a plasmid found in a heterothallic and a pseudohomothallic species in the same global area; these cases might have arisen from more recent horizontal transmission or introgression.

    Malaysia, which currently uses the informed consent system (ICS), is suffering from a severe shortage of organs for transplantation. Family members of dialysis patients (FMDPs) are expected to have a positive attitude toward deceased organ donation (DOD) because they have a close relative in need of a kidney donation. This study explores FMDPs' attitude toward DOD under the ICS and the presumed consent system (PCS). The attitude of 350 FMDPs toward DOD under the ICS and PCS were sought between June and October 2013 in 3 dialysis institutions in Kuala Lumpur, Malaysia. Under the ICS, 6.6% of respondents were registered donors, 6.6% were ready to register at the time of the survey, 38.6% were willing to donate but not ready to register at the time of the survey, and 48.2% were unwilling to donate organs upon death. If the PCS were implemented, 57.7% of respondents (28.7% of the willing donors and 88.7% of the unwilling respondents) stated that they would officially object to organ donation. FMDPs' attitude toward DOD is not more positive or significantly better than that of the general public (based on earlier studies). The PCS may increase the number of donors, but it may also worsen the attitude of FMDPs toward DOD. Strategies aiming to promote DOD in Malaysia should be revised, and should perhaps be focused on enhancing trust of the medical system.

    This study aimed to analyze what looking after physically disabled persons with spinal cord injury by trauma means to their caregivers and family members. The analysis of the testimony of eight caregivers, obtained in open interviews, which was methodologically based on the Social Representations Theory (SR), pointed out two main routes: coping with the suffering process in care practice and the troubled waters that permeate this suffering process. These two routes, characterized as SR Central Core and Peripheral System, respectively, consisted of themes like the way of looking at impairment, affectivity, religiosity, social-economical changes and (lack of) technical and institutional support. The results show a handicapped caregiver dedicated to look after someone who is physically disabled, considered incapacitated, and who leads his or her chores with distress and privations, based on guilt and religiosity, supported by ambiguous affection and affected by deteriorating social-economical changes and (lack of) technical and institutional support to practice an activity that implies so many peculiarities. The transformation alternatives of these caregivers' daily life principally lead to a symbiosis of disability with the patient - to live for the physically disabled - or yet, for a few, a sketch to restart personal life projects - to live with the physically disabled.

    Vertebrates express two members of the dystrophin gene family. The prototype, dystrophin, is expressed in muscle and neural tissue, and is defective in the human disorders Duchenne and Becker muscular dystrophy (DMD, BMD). The dystrophin homologue utrophin is more generally expressed but has not yet been associated with a genetic disorder. The function of neither protein is clear. A comparison of human utrophin with the known dystrophins (human, mouse, chicken, Torpedo) suggests that dystrophin and utrophin diverged before the vertebrate radiation. We have used reverse-transcript PCR (RT-PCR) directed by degenerate primers to characterize dystrophin and utrophin transcripts from a range of vertebrate and invertebrate animals. Our results suggest that the duplication leading to distinct dystrophin and utrophin genes occurred close to the point of divergence of urochordates from the cephalochordate-vertebrate lineage. This divergence may have occurred to fulfill a novel role which arose at this point, or may reflect a need for separate regulation of the neuromuscular and other functions of the ancient dystrophin. Our data include sequences of the first non-human utrophins to be characterized, and show these to be substantially more divergent than their cognate dystrophins. In addition, our results provide a large body of information regarding the tolerance of amino acid positions in the cysteine-rich and C-terminal domains to substitution. This will aid the interpretations of DMD and BMD missense mutations in these regions.

    Langerhans cells (LC) are skin-specific members of the dendritic cell (DC) family. DC are unique among APC for their capacity to activate immunologically naive T cells, but little is known about their chemotactic recruitment of T cells. We now report that LC produce macrophage inflammatory protein-1 gamma (MIP-1 gamma), a newly identified CC chemokine. MIP-1 gamma mRNA was detected in epidermal cells freshly procured from BALB/c mice, and depletion of I-A+ epidermal cells (i.e., LC) abrogated that expression. MIP-1 gamma mRNA was detected in the XS52 LC-like DC line as well as by 4F7+ splenic DC and granulocyte-macrophage CSF-propagated bone marrow DC. XS52 DC culture supernatants contained 9 and 10.5 kDa immunoreactivities with anti-MIP-1 gamma Abs. We observed in Boyden chamber assays that 1) XS52 DC supernatant (added to the lower chambers) induced significant migration by splenic T cells; 2) this migration was blocked by the addition of anti-MIP-1 gamma in the lower chambers or by rMIP-1 gamma in the upper chambers; and 3) comparable migration occurred in both CD4+ and CD8+ T cells and in both activated and nonactivated T cells. We conclude that mouse DC (including LC) have the capacity to elaborate the novel CC chemokine MIP-1 gamma, suggesting the active participation of DC in recruiting T cells before activation.

    Full Text Available Purpose: Nurses and physicians must be competent enough to provide care for the clients. As a lack of knowledge and a poor attitude result in a low performance of delivering care, this study aimed to explore the nurses versus physicians’ knowledge, attitude, and performance on care for the family members of dying patients (FMDPs. Methods: This descriptive study was conducted at the educational hospitals in Isfahan, Iran. The samples were 110 nurses and 110 physicians. The data were collected through a convenience sampling method and using a valid and reliable questionnaire. Results: The average knowledge, attitude, and performance on care for the FMDPs were not significantly different between nurses and physicians (p>0.05. The majority of nurses (55.4% and physician (63.6% were at a moderate and a fair level of knowledge of care for the FMDPs. Most of the nurses (81% and physicians (87.3% had a positive attitude towards caring the FMDPs. Most of the nurses (70% and physicians (86.3% had a moderate and fair performance. Conclusion: Having enough knowledge and skills, and a positive attitude are necessary for caring the FMDPs. Nurses’ and physicians' competencies must be improved through continuing educational programs and holding international and national conferences with a focus on the palliative care.

    Full Text Available Purpose: The present study was undertaken to assess the level of awareness on legislations relating to intellectual disability among family members in India.Method: A sample of 103 respondents attending home based training services for their wards at National Institute for the Mentally Handicapped (NIMH, India, were administered a thirty item questionnaire, classified into awareness of legislations, awareness of rights, concessions and benefits and life cycle needs.Results: There is a moderate level of awareness on legislative aspects. Educated respondents showed better awareness about legislations than less educated persons. Respondents were better aware of benefits and concessions because of their direct utility in their day-to-day activities.Conclusion: There is a need for creation of awareness and sensitization among parents and caregivers having persons with intellectual disability to enable them to receive optimum benefits. To reach the uneducated population the materials must also be made available in non-print media such as television, posters and illustrated pamphlets.

    The phytohormone ethylene regulates many aspects of plant growth, development, and environmental responses. Much of the developmental regulation of ethylene responses in tomato (Lycopersicon esculentum) occurs at the level of hormone sensitivity. In an effort to understand the regulation of ethylene responses, we isolated and characterized tomato genes with sequence similarity to the Arabidopsis ETR1 (ethylene response 1) ethylene receptor. Previously, we isolated three genes that exhibit high similarity to ETR1 and to each other. Here we report the isolation of two additional genes, LeETR4 and LeETR5, that are only 42% and 40% identical to ETR1, respectively. Although the amino acids known to be involved in ethylene binding are conserved, LeETR5 lacks the histidine within the kinase domain that is predicted to be phosphorylated. This suggests that histidine kinase activity is not necessary for an ethylene response, because mutated forms of both LeETR4 and LeETR5 confer dominant ethylene insensitivity in transgenic Arabidopsis plants. Expression analysis indicates that LeETR4 accounts for most of the putative ethylene-receptor mRNA present in reproductive tissues, but, like LeETR5, it is less abundant in vegetative tissues. Taken together, ethylene perception in tomato is potentially quite complex, with at least five structurally divergent, putative receptor family members exhibiting significant variation in expression levels throughout development.

    The highly conserved LC8/DYNLL family proteins were originally identified in axonemal dyneins and subsequently found to function in multiple enzyme systems. Genomic analysis uncovered a third member (LC10) of this protein class in Chlamydomonas. The LC10 protein is extracted from flagellar axonemes with 0.6 M NaCl and cofractionates with the outer dynein arm in sucrose density gradients. Furthermore, LC10 is specifically missing only from axonemes of those strains that fail to assemble outer dynein arms. Previously, the oda12-1 insertional allele was shown to lack the Tctex2-related dynein light chain LC2. The LC10 gene is located ∼2 kb from that of LC2 and is also completely missing from this mutant but not from oda12-2, which lacks only the 3′ end of the LC2 gene. Although oda12-1 cells assemble outer arms that lack only LC2 and LC10, this strain exhibits a flagellar beat frequency that is consistently less than that observed for strains that fail to assemble the entire outer arm and docking complex (e.g., oda1). These results support a key regulatory role for the intermediate chain/light chain complex that is an integral and highly conserved feature of all oligomeric dynein motors. PMID:18579685

    Malaria is one of the deadliest human diseases and efforts to control it have been difficult due to the protozoan parasites' complex biology. Malaria merozoite invasion of erythrocytes is an essential part of blood-stage infections. The invasion process is mediated by numerous parasite molecules, such as EBA-175, a member of the ebl family of erythrocyte binding proteins. We have identified maebl, an ebl paralogue, in Plasmodium falciparum and found it highly conserved with its orthologues in P. yoelii and P. berghei, but distinct from other Plasmodium ebl. Importantly, the putative MAEBL ligand domains are highly conserved and are similar to AMA-1, but not the consensus DBL ligand domains present in all other ebl. In mature merozoites, MAEBL localized with rhoptry proteins (RhopH2, RAP-1), including surface localization with RhopH2, but not microneme proteins (EBA-175, BAEBL). MAEBL appears as proteolytically processed fragments in P. falciparum parasites. The amino cysteine-rich ligand domains were present primarily in culture supernatants, while the carboxyl cysteine-rich domain adjacent to the transmembrane domain was preferentially isolated from Triton X-100 extracted fractions. These data indicate that the primary structure of maebl is highly conserved among Plasmodium species, while its characteristics demonstrate a function unique among the ebl proteins.

    Plant cells contain distinct compartments such as the nucleus, the endomembrane system comprising the endoplasmic reticulum and Golgi apparatus, peroxisomes, vacuoles, as well as mitochondria and chloroplasts. All of these compartments are surrounded by 1 or 2 limiting membranes and need to import proteins from the cytosol. Previous work led to the conclusion that mitochondria and chloroplasts use structurally different protein import machineries in their outer and inner membranes for the uptake of cytosolic precursor proteins. Our most recent data show that there is some unexpected overlap. Three members of the family of preprotein and amino acid transporters, PRAT, were identified in chloroplasts that mediate the uptake of transit sequence-less proteins into the inner plastid envelope membrane. By analogy, mitochondria contain with TIM22 a related PRAT protein that is involved in the import of transit sequence-less proteins into the inner mitochondrial membrane. Both mitochondria and chloroplasts thus make use of similar import mechanisms to deliver some of their proteins to their final place. Because single homologs of HP20- and HP30-like proteins are present in algae such as Chlamydomonas, Ostreococcus, and Volvox, which diverged from land plants approximately 1 billion years ago, it is likely that the discovered PRAT-mediated mechanism of protein translocation evolved concomitantly with the secondary endosymbiotic event that gave rise to green plants.

    Objective:To discuss progesterone and adiponectin receptor family member 3 expression and clinical significance in breast cancer tissues. Method:A total of 90 cases with breast cancer who were admitted in our hospital from Jan 2000 to Jan 2010 were selected. Meanwhile, normal tumor-adjacent breast tissues were selected as comparison. Diagnosis of all patients was confirmed by postoperative pathological examinations. Immunohistochemistry method was adopted to detect PAQR3 protein expression in breast cancer tissues and normal tumor-adjacent breast tissues and its clinical significance was discussed. Results:PAQR3 protein positive expression rate in breast cancer tissues was 25.6%, which was significantly lower than that (78.9%) in normal tumor-adjacent breast tissues;PAQR3 protein positive expression rate had nothing to do with age, tumor size, pathological types and differentiated degree of patients, but had significant correlation with TNM staging and lymphatic metastasis existence of patients. Kaplan–Meier survival analysis results showed that five years survival rate of patients with PAQR3 protein positive expression was significantly higher than whom with negative expression. Conclusion:PAQR3 protein expression in breast cancer tissues was significantly reduced, which indicated that PAQR3 protein possibly played an important role in pathogenesis of breast cancer.

Design: Program implementation and subsequent survey of team members. Setting: A large multisite FHT in Toronto, Ontario. Participants: Health professionals of the FHT. Main outcome measures: Usage patterns and self-reported perceptions of the Facebook group by team members. Results: At the time of the evaluation survey, the Facebook group had 43 members (37.4% of all FHT members. Activity in the group was never high, and posts by team members who were not among the researchers were infrequent throughout the study period. The content of posts fell into two broad categories: 1 information that might be useful to various team members and 2 questions posed by team members that others might be able to answer. Of the 26 team members (22.6% who completed the evaluation survey, many reported that they never logged into the Facebook page (16 respondents, and never used it to communicate with team members outside of their own site of practice (19 respondents. Only six respondents reported no concerns with using Facebook as a professional communication tool; the most frequent concerns were regarding personal and patient privacy. Conclusion: The use of social media by health care practitioners is becoming ubiquitous. However, the issues of privacy concerns and determining how to use social media without adding to provider workload must be addressed to make it a useful tool in health care.

    NK-T-B antigen (NTBA) is a CD2 family member that functions as a coreceptor in human NK cell activation. Several receptor/ligand interactions occur between different members of this molecular family. In this study, in order to identify the natural ligand of NTBA, we produced a chimeric protein formed by the NTBA extracellular region fused with the Fc portion of human IgG1 (termed NTBA-Fc*). NTBA-Fc* specifically binds to NTBA cell transfectants but not to cells transfected with other CD2 family members including CD2, CD48, CD84, CD150, CD229, and CD244. Moreover, NTBA-Fc* also binds to NTBA(+) but not to NTBA(-) T cell lines. Enzyme-linked immunosorbent assays, plasmon resonance analysis, as well as NTBA-Fc*-mediated down-regulation of NTBA surface expression further confirmed the occurrence of NTBA/NTBA homophilic interaction. Functionally, in NK cells, NTBA-Fc* promoted a strong production of IFN-gamma and TNF-alpha. Moreover, NTBA-transfected targets displayed increased susceptibility to NK-mediated killing as compared to untransfected cells and this effect was specifically inhibited by anti-NTBA mAb. Altogether our data indicate that NTBA is characterized by self recognition.

    2015-05-01

    Bactericidal/permeability-increasing protein fold-containing family member A1 (BPIFA1), formerly known as SPLUNC1, is one of the most abundant proteins in respiratory secretions and has been identified with increasing frequency in studies of pulmonary disease. Its expression is largely restricted to the respiratory tract, being highly concentrated in the upper airways and proximal trachea. BPIFA1 is highly responsive to airborne pathogens, allergens, and irritants. BPIFA1 actively participates in host protection through antimicrobial, surfactant, airway surface liquid regulation, and immunomodulatory properties. Its expression is modulated in multiple lung diseases, including cystic fibrosis, chronic obstructive pulmonary disease, respiratory malignancies, and idiopathic pulmonary fibrosis. However, the role of BPIFA1 in pulmonary pathogenesis remains to be elucidated. This review highlights the versatile properties of BPIFA1 in antimicrobial protection and its roles as a sensor of environmental exposure and regulator of immune cell function. A greater understanding of the contribution of BPIFA1 to disease pathogenesis and activity may clarify if BPIFA1 is a biomarker and potential drug target in pulmonary disease.

    Advocates for quality and safety have called for healthcare that is patient-centred and decision-making that involves patients. The aim of the paper is to explore the barriers and facilitators to patient-centred care in the hospital discharge process. A qualitative study using purposive sampling of 192 individual interviews and 26 focus group interviews was conducted in five European Union countries with patients and/or family members, hospital physicians and nurses, and community general practitioners and nurses. A modified Grounded Theory approach was used to analyse the data. The barriers and facilitators were classified into 15 categories from which four themes emerged: (1) healthcare providers do not sufficiently prioritise discharge consultations with patients and family members due to time restraints and competing care obligations; (2) discharge communication varied from instructing patients and family members to shared decision-making; (3) patients often feel unprepared for discharge, and postdischarge care is not tailored to individual patient needs and preferences; and (4) pressure on available hospital beds and community resources affect the discharge process. Our findings suggest that involvement of patients and families in the preparations for discharge is determined by the extent to which care providers are willing and able to accommodate patients' and families' capabilities, needs and preferences. Future interventions should be directed at healthcare providers' attitudes and their organisation's leadership, with a focus on improving communication among care providers, patients and families, and between hospital and community care providers.

    Full Text Available Myotonic dystrophy type 1 (DM1 is caused by the expansion of an unstable CTG repeat located in the 3′-UTR of (DMPK the DM protein kinase gene. Patients with DM1 have expansions of greater than 50 repeats and up to many thousands. In the present study we aimed to evaluate the utility of TP-PCR in diagnostics as well as the assessment of premutation carriers in proband families. Twenty-seven DM1 cases were enrolled (from twenty-six families and the 13 families of these cases came forward for family screening. The patient group constitute 22 males and 5 females and the average age of onset was 32.8 years (range 17 to 52. All clinically diagnosed DM1 cases and their family members DNA samples were analyzed by TP-PCR. All the cases were found to be positive for the CTG repeat expansion. Among those five families, four had at least an asymptomatic carrier. In the remaining one family other than the proband none was found to be neither affected nor asymptomatic. We reconfirmed the utility of PCR based screening for DM1 as being reliable and rapid molecular test and it should be used as an initial screening test for all patients with DM and their family members for initial screening purpose.

    Full Text Available Abstract Background Studies of family reactions following teenage suicide are hampered by the psychological difficulties of approaching families and recruiting an unbiased sample of study subjects. By using a small but consecutive series of cases, we examined the qualitative aspects of loosing a teenage family member due to suicide. Such an understanding is important for future organisation of proper programs that provide professional support in the grief process. Methods From a large project on teenage unnatural death in northern Sweden 1981–2000 (including 88 suicides, 13 cases from 1995 through 1998 were retrospectively identified and consecutively analysed. Ten families agreed to participate. The open interviews took place 15 to 25 months after the suicide. The information gathered was manually analysed according to a grounded theory model, resulting in allocation of data into one of three domains: post-suicidal reactions, impact on daily living, and families' need for support. Results Teenager suicide is a devastating trauma for the surviving family and the lack of sustainable explanations for the suicide is a predominant issue in the grief process. The prolonged social and psychological isolation of the families in grief should be challenged. At the time of the interview, the families were still struggling with explaining why the suicide occurred, especially since most suicides had occurred without overt premonitory signs. The bereaved family members were still profoundly affected by the loss, but all had returned to an ostensibly normal life. Post-suicide support was often badly timed and insufficient, especially for younger siblings. Conclusion Family doctors can organise a long-term, individually formulated support scheme for the bereaved, including laymen who can play a most significant role in the grief process. There is also a need for better understanding of the families who have lost a teenager whom committed suicide and for the

  2. Elucidating the role of highly homologous Nicotiana benthamiana ubiquitin E2 gene family members in plant immunity through an improved virus-induced gene silencing approach.

    Virus-induced gene silencing (VIGS) has been used in many plant species as an attractive post transcriptional gene silencing (PTGS) method for studying gene function either individually or at large-scale in a high-throughput manner. However, the specificity and efficiency for knocking down members of a highly homologous gene family have remained to date a significant challenge in VIGS due to silencing of off-targets. Here we present an improved method for the selection and evaluation of gene fragments used for VIGS to specifically and efficiently knock down members of a highly homologous gene family. Using this method, we knocked down twelve and four members, respectively of group III of the gene family encoding ubiquitin-conjugating enzymes (E2) in Nicotiana benthamiana. Assays using these VIGS-treated plants revealed that the group III E2s are essential for plant development, plant immunity-associated reactive oxygen species (ROS) production, expression of the gene NbRbohB that is required for ROS production, and suppression of immunity-associated programmed cell death (PCD) by AvrPtoB, an effector protein of the bacterial pathogen Pseudomons syringae. Moreover, functional redundancy for plant development and ROS production was found to exist among members of group III E2s. We have found that employment of a gene fragment as short as approximately 70 base pairs (bp) that contains at least three mismatched nucleotides to other genes within any 21-bp sequences prevents silencing of off-target(s) in VIGS. This improved approach in the selection and evaluation of gene fragments allows for specific and efficient knocking down of highly homologous members of a gene family. Using this approach, we implicated N. benthamiana group III E2s in plant development, immunity-associated ROS production, and suppression of multiple immunity-associated PCD by AvrPtoB. We also unraveled functional redundancy among group III members in their requirement for plant development and

  3. Comprehensive Identification of Kruppel-Like Factor Family Members Contributing to the Self-Renewal of Mouse Embryonic Stem Cells and Cellular Reprogramming.

    Full Text Available Pluripotency is maintained in mouse embryonic stem (ES cells and is induced from somatic cells by the activation of appropriate transcriptional regulatory networks. Krüppel-like factor gene family members, such as Klf2, Klf4 and Klf5, have important roles in maintaining the undifferentiated state of mouse ES cells as well as in cellular reprogramming, yet it is not known whether other Klf family members exert self-renewal and reprogramming functions when overexpressed. In this study, we examined whether overexpression of any representative Klf family member, such as Klf1-Klf10, would be sufficient for the self-renewal of mouse ES cells. We found that only Klf2, Klf4, and Klf5 produced leukemia inhibitory factor (LIF-independent self-renewal, although most KLF proteins, if not all, have the ability to occupy the regulatory regions of Nanog, a critical Klf target gene. We also examined whether overexpression of any of Klf1-Klf10 would be sufficient to convert epiblast stem cells into a naïve pluripotent state and found that Klf5 had such reprogramming ability, in addition to Klf2 and Klf4. We also delineated the functional domains of the Klf2 protein for LIF-independent self-renewal and reprogramming. Interestingly, we found that both the N-terminal transcriptional activation and C-terminal zinc finger domains were indispensable for this activity. Taken together, our comprehensive analysis provides new insight into the contribution of Klf family members to mouse ES self-renewal and cellular reprogramming.

  4. Maastricht Criteria Targeting and Credit Growth: Empirical Evidences for the New EU Member States

    Full Text Available The study aims to investigate the impact of credit growth on the Maastricht criteria targeting process in the new member states of the European Union. The methodological framework is based on a two-compenent transmission mechanism represented by the output gap and the nonperforming loans. The empirical analysis consists of a set of simplified econometric models, built by panel estimates using annual data from 2000 to 2011. Statistical results revealed the existence of a reaction of long term interest rates to the developments in sovereign risk premium, determined, in turn, by the impact of the mutual reinforcing between lending rate and output gap on the loan portfolio quality dynamics. Strengthening prudential conduct of monetary policy with a conservative macro-prudential policy is a critical need for increased resilience of nominal convergence to exogenous shocks, given that containing the volatility of economic activity depends in a decisive way, on succeding to maintain credit growth levels close to economic growth potential.

    2015-01-01

    RHO GTPases, members of the RAS superfamily of small GTPases, are adhesion and growth factor-activated molecular switches that play important roles in tumor development and progression. When activated, RHO-family GTPases such as RAC1, CDC42, and RHOA, transmit signals by recruiting a variety of effector proteins, including the protein kinases PAK, ACK, MLK, MRCK, and ROCK. Genetically induced loss of RHO function impedes transformation by a number of oncogenic stimuli, leading to an interest in developing small-molecule inhibitors that either target RHO GTPases directly, or that target their downstream protein kinase effectors. Although inhibitors of RHO GTPases and their downstream signaling kinases have not yet been widely adopted for clinical use, their potential value as cancer therapeutics continues to facilitate pharmaceutical research and development and is a promising therapeutic strategy.

    BACKGROUND: This study evaluated stress management training to improve mental health, social interaction and family function among adolescents of families with one Human Immunodeficiency Virus (HIV) positive member. METHODS: There were 34 adolescents (13-18 years old) with at least one family member living with HIV from whom finally 15 attended the study and participated in 8 weekly sessions of stress management training. The tests used in this study were: Strengths and Difficulties Questionnaire (self and parent report), General Health Questionnare-28 (GHQ-28) and Family Assessment Device (FAD), conducted before, after and three months after the intervention. The collected data were analyzed by repeated measure test using SPSS software (Version 18.0). RESULTS: Adolescents with one HIV positive family member showed high level of emotional problem (40%) and conduct problem (33.3%). There was a significant difference between before, after and 3months after intervention based on GHQ-28 mean scores and FAD mean sores (p < 0.001). There was a significant difference between mean scores of peers’ relationship based on SDQ (self report and parents report forms) before and after intervention, but there was no significant difference between mean scores of pro social behavior based on SDQ (self report and parents report forms) in all three stages (before, after and three months after intervention). CONCLUSIONS: Stress management training is effective in improving mental health, family function and social interaction among adolescents living with parents infected with HIV/AIDS. PMID:22091302

    2015-02-01

    This paper is a development of a doctoral thesis presented at the Federal University of Espírito Santo. It seeks to analyze the elucidation of needs, development of supply and demand in the provision of care and the relationship between mental health professionals and family members of people with mental disorders. A qualitative research approach was used as the method of choice to achieve the proposed objectives. Semi-structured interviews were conducted with mental health professionals from two psychosocial care centers (CAPS) in the city of Vitória, Espírito Santo, and with family members of frequenters of these institutions. After thematic analysis of content, senses, meanings and values assigned to the needs, supplies and demands present in this relationship were revealed. It highlighted the disparity between supply and demand and the lack of awareness of the needs of family members and their demands related to the routines of mental institutions. Using ethics in the philosophy of Spinoza as a benchmark, the ramifications of this process are discussed in the meetings between mental health professionals and family members of people with mental disorders and the micropolitics of the provision of care in the context of these actors.

  9. Does Death of a Family Member Moderate the Relationship between Religious Attendance and Depressive Symptoms? The HUNT Study, Norway

    2012-01-01

    Full Text Available Background. The death of a family member is a stressful life event and can result in an increased level of depressive symptoms. Previous American research has shown inverse relationships between religious involvement and depression. European investigations are few and findings inconsistent; different contexts may have an important influence on findings. We therefore investigated the relationship between attendance at church/prayer house and depressive symptoms, and whether this relationship was moderated by the death of a close family member, in Norway. Methods. A population-based sample from the Nord-Trøndelag Health Study, Norway (HUNT 3, N=37,981, was the population examined. Multiple regression and interaction tests were utilised. Results. Religious attendees had lower scores on depressive symptoms than non-attendees; death of a close family member moderated this relationship. The inverse relationships between attendance at church/prayer house and depressive symptoms were greater among those experiencing the death of an immediate family member in the last twelve months compared to those without such an experience, with men's decrease of depressive symptoms more pronounced than women's. Conclusion. In a population-based study in Norway, attendance at church/prayer house was associated with lower depressive symptoms, and the death of a close relative and gender moderated this relationship.

    Bcl-2 family members are important regulators of cell fate in normal organ development and in disease status. Pro- and anti-apoptotic members of this family function through a complex network of homo- and hetero-dimers to determine whether a cell lives or dies. Members of the Bcl-2 family are classically recognized for their role in apoptosis, yet emerging evidence has highlighted their importance in the regulation of cell cycle. Cellular proliferation, differentiation and death accompany early placental development of the trophoblast lineage. We have recently reported on the expression and function of two Bcl-2 family members in normal placental development, namely the pro-apoptotic Mtd/Bok, and its anti-apoptotic partner Mcl-1 and have found that their expression is upregulated by low oxygen, a key mediator of trophoblast cell proliferation in early placentation. Interestingly, we have also reported that the expression of the Mtd/Mcl-1 system is altered in preeclampsia, a placental pathology associated with a status of oxidative stress and typically characterized by an immature proliferative trophoblast phenotype and excessive trophoblast cell death. In this pathology levels of pro-apototic Mtd-L and Mtd-P are increased and anti-apoptotic Mcl-1 is cleaved in to a pro-apoptotic isoform. Disruption in Mtd/Mcl-1 expression seen in preeclampsia may contribute to both the increased apoptosis and hyperproliferative nature of this disorder.

    Understanding the difficulties and needs of the family carers in taking care of a person with ID can facilitate the development of appropriate intervention programmes and services to strengthen their caring capacity and empower them to continue with their caring roles. This study aims to explore ageing family carers' caregiving experiences and the plans they have to provide care for themselves and their ageing children with mild or moderate intellectual disability (ID). A constructivist grounded theory will be used to interview around 60 carers who have a family member with mild or moderate ID and attending sheltered workshops in Hong Kong. Constant comparative analysis methods will be used for data analysis. The theory will capture family caregiving experiences and the processes of carers in addressing caregiving needs, support received and plans to continue to provide care for themselves and their relatives with ID in their later life. New insights into the emerging issues, needs and plights of family caregivers will be provided to inform the policies and practices of improving the preparation for the ageing process of the persons with ID, and to better support the ageing carers. The theoretical framework that will be generated will be highly practical and useful in generating knowledge about factors that influence the caregiving processes; and, tracking the caregiving journey at different time-points to clearly delineate areas to implement practice changes. In this way, the theoretical framework will be highly useful in guiding timely and appropriate interventions to target at the actual needs of family carers as they themselves are ageing and will need to continue to take care of their family members with ID in the community.

    Separation of an extract of corpora cardiaca from the protea beetle, Trichostetha fascicularis, by single-step RP (reverse-phase)-HPLC and monitoring of tryptophan fluorescence resulted in two distinctive peaks, the material of which mobilized proline and carbohydrates in a bioassay performed using the beetle. Material from one of these peaks was; however, inactive in the classical bioassays of locusts and cockroaches that are used for detecting peptides belonging to the AKH (adipokinetic hormone) family. After enzymatically deblocking the N-terminal pyroglutamic acid (pGlu) residue in the peptide material and sequencing by Edman degradation, a partial sequence was obtained: (pGlu)-Ile-Asn-Met-Thr-Xaa-Gly-Trp. The complete sequence was deduced from ESI-MSn (electrospray ionization multi-stage-MS); position six was identified as a phosphothreonine residue and the C-terminus is amidated. The peptide, code-named Trifa-CC, was chemically synthesized and used in confirmatory experiments to show that the primary structure had been correctly assigned. To our knowledge, this is the first report of a phosphorylated invertebrate neuropeptide. Synthetic Trifa-CC co-elutes with the natural peptide, found in the gland of the protea beetle, after RP-HPLC. Moreover, the natural peptide can be dephosphorylated by alkaline phosphatase and the product of that reaction has the same retention time as a synthetic nonphosphorylated octapeptide which has the same sequence as Trifa-CC. Finally, synthetic Trifa-CC has hypertrehalosaemic and hyperprolinaemic biological activity in the protea beetle, but even high concentrations of synthetic Trifa-CC are inactive in locusts and cockroaches. Hence, the correct peptide structure has been assigned. Trifa-CC of the protea beetle is an unusual member of the AKH family that is unique in its post-translational modification. Since it increases the concentration of carbohydrates and proline in the haemolymph when injected into the protea beetle, and

    Full Text Available Background. A discoid meniscus is a thickened variant of the normal C-shaped meniscus prone to injury. Discoid medial meniscal tears have rarely been reported within families and may suggest familial or developmental origins. Methods. We report the cases of two Caucasian brothers with symptomatic discoid medial meniscus tears. A literature review was conducted addressing discoid medial meniscus and cases of familial meniscus tears. Case Presentation. Physically active brothers presented with progressively worsening knee pain. MRI revealed medial meniscus tears in both brothers. The family history of medial meniscus tears in their mother and the discoid medial meniscus injuries found on arthroscopy suggested evidence for familial discoid medial meniscus tears. Conclusions. Discoid medial meniscus tears within a family have not been previously reported. Two cases of families with discoid lateral meniscus tears have been reported. Discoid medial meniscus is rare relative to the discoid lateral meniscus and predisposes children to symptomatic tears.

    Full Text Available Survivors of human trafficking often experience considerable financial difficulties upon exiting human trafficking, including pressure to provide financially for their families, challenges securing employment, lack of savings, and familial debt. Few evaluations have been conducted of reintegration support interventions addressing financial vulnerability among trafficking survivors. In this article, we present findings from a participatory assessment of the BARUG program, a matched savings and financial capability program for survivors of human trafficking and their family members in the Philippines. Photovoice was used to understand the experiences of two cohorts of BARUG participants. Survivors collaborated with research team members in conducting thematic analysis of transcripts from the photovoice sessions. Themes included: the positive emotional impact of financial wellness, overcoming the challenges of saving, applying financial management skills in daily decision making, developing a habit of savings, building a future-oriented mindset, receiving guidance and enlightenment, the learning process, and the change process. Findings reinforce the importance of interventions to support trafficked persons and their family members in getting out of debt and accumulating emergency savings, while also providing emotional support to survivors in coping with family financial pressures. The study also highlights the value of using participatory research methods to understand the experiences of trafficked persons. URN: http://nbn-resolving.de/urn:nbn:de:0114-fqs1702116

    ABSTRACT Objective: women are more likely to give birth at a health facility when their families agree with the birthplace. However, in rural areas of Tanzania, women are often marginalized from decision-making. This study predicted birthplace intention and identified factors to reduce perceptional gaps among pregnant women, husbands and family members. Method: explanatory cross-sectional survey was conducted in three villages in North Eastern Tanzania. Participants were 138 pregnant women and their families who answered the Birth Intention Questionnaire (BIQ), measuring knowledge, attitude, perceived behavioral control, subjective norms and intention for birthplace. Descriptive analysis, ANOVA, Chi-square, and multiple linear regression was used to analyze the data. Results: the regression model showed that knowledge, perceived behavioral control, and subjective norms predicted intention for birthplace (R2 = .28). While 81% of pregnant women thought their husbands were decision-makers for their birth, only 38% of husbands and 37% of family members agreed. Pregnant women had significantly lower scores on the item “I will prepare for childbirth with my family” compared with husbands (p < .01) and other family members (p < .001). Conclusion: providing evidence-based birth preparation and reducing the identified perceptual gaps may enhance women’s intention to deliver at health facilities. PMID:28146180

    Full Text Available Abstract Background Classical nuclear localization signal (NLS dependent nuclear import is carried out by a heterodimer of importin α and importin β. NLS cargo is recognized by importin α, which is bound by importin β. Importin β mediates translocation of the complex through the central channel of the nuclear pore, and upon reaching the nucleus, RanGTP binding to importin β triggers disassembly of the complex. To date, six importin α family members, encoded by separate genes, have been described in humans. Results We sequenced and characterized a seventh member of the importin α family of transport factors, karyopherin α 7 (KPNA7, which is most closely related to KPNA2. The domain of KPNA7 that binds Importin β (IBB is divergent, and shows stronger binding to importin β than the IBB domains from of other importin α family members. With regard to NLS recognition, KPNA7 binds to the retinoblastoma (RB NLS to a similar degree as KPNA2, but it fails to bind the SV40-NLS and the human nucleoplasmin (NPM NLS. KPNA7 shows a predominantly nuclear distribution under steady state conditions, which contrasts with KPNA2 which is primarily cytoplasmic. Conclusion KPNA7 is a novel importin α family member in humans that belongs to the importin α2 subfamily. KPNA7 shows different subcellular localization and NLS binding characteristics compared to other members of the importin α family. These properties suggest that KPNA7 could be specialized for interactions with select NLS-containing proteins, potentially impacting developmental regulation.

  7. Paradoxical role of an Egr transcription factor family member, Egr2/Krox20, in learning and memory

    Full Text Available It is well established that Egr1/zif268, a member of the Egr family of transcription factors, is critical for the consolidation of several forms of memories. Recently, the Egr3 family member has also been implicated in learning and memory. Because Egr family members encode closely related zinc-finger transcription factors sharing a highly homologous DNA binding domain that recognises the same DNA sequence, they may have related functions in brain. Another Egr family member expressed in brain, Egr2/Krox20 is known to be crucial for normal hindbrain development and has been implicated in several inherited peripheral neuropathies; however, due to Egr2-null mice perinatal lethality, its potential role in cognitive functions in the adult has not been yet explored. Here, we generated Egr2 conditional mutant mice allowing postnatal, forebrain-specific Cre-mediated Egr2 excision and tested homozygous, heterozygous and control littermates on a battery of behavioural tasks to evaluate motor capacity, exploratory behaviour, emotional reactivity and learning and memory performance in spatial and non-spatial tasks. Egr2-deficient mice had no sign of locomotor, exploratory or anxiety disturbances. Surprisingly, they also had no impairment in spatial learning and memory, taste aversion memory or fear memory using a trace conditioning paradigm. On the contrary, Egr2-deficient mice had improved performance in motor learning on a rotarod, and in object recognition memory. These results clearly do not extend the phenotypic consequences resulting from either Egr1 or Egr3 loss-of-function to Egr2. In contrast, they indicate that Egr family members may have different, and in certain circumstances antagonistic functions in the adult brain.

    The proapoptotic Bcl-2 family member PUMA is a critical regulator of apoptosis. We have previously shown that PUMA plays a pivotal role in the apoptosis associated with skeletal myoblast differentiation and that a MyoD-dependent mechanism is responsible for the increased expression of PUMA in these cells. Herein, we report that the increased expression of PUMA under these conditions involves regulation at the level of translation. Specifically, we have found that the increase in PUMA protein levels occurs under conditions of decreased total protein synthesis, eIF2-alpha phosphorylation and hypophosphorylation of eIF4E-BP, suggesting that PUMA translation is proceeding via an alternative initiation mechanism. Polyribosome analysis of PUMA mRNA further corroborated this suggestion. A combination of in vitro and ex vivo (cellular) approaches has provided evidence suggesting that PUMA mRNA 5'UTR harbors an Internal Ribosome Entry Site (IRES) element. Using mono- and bi-cistronic reporter constructs, we have delineated an mRNA fragment that allows for cap-independent translation in vitro and ex vivo (in skeletal myoblasts) in response to culture in differentiation media (DM), or in response to treatment with the DNA-damaging agent, etoposide. This mRNA fragment also supports translation in HeLa and 293T cells. Thus, our data has revealed a novel IRES-mediated regulation of PUMA expression in several cell types and in response to several stimuli. These findings contribute to our understanding and potential manipulation of any developmental or therapeutic scenario involving PUMA.

    Although several studies have reported that child physical abuse increased the risk for bullying involvement, the effect of current violence from adult family members (CVA) on bullying involvement and suicidal feelings among adolescents has not been sufficiently examined. This study investigated the association of CVA with adolescent bullying involvement and the interaction effect of CVA and bullying involvement on suicidal feelings. This cross-sectional study used data from a school-based survey with a general population of adolescents (grades 7 to 12). Data were collected using a self-report questionnaire completed by 17,530 students. Logistic regression analyses were performed to explore the association of CVA with adolescent bullying involvement and suicidal feelings. The overall response rate was 90.2%. The odds of students being characterized as bullies, victims, and bully-victims were higher among adolescents with CVA than without CVA (odds ratios (OR) = 2.9, 95% confidence interval (CI), [2.3-3.7], 4.6 [3.6-5.8], and 5.8 [4.4-7.6], respectively). Both CVA (OR = 3.4 [95% CI 2.7-4.3]) and bullying (bullies, victims, and bully-victims; OR = 2.0 [95% CI 1.6-2.6], 4.0 [3.1-5.1], 4.1 [3.0-5.6], respectively), were associated with increased odds of current suicidal feelings after adjusting for confounding factors. Furthermore, positive additive effects of CVA and all three types of bullying involvement on suicidal feelings were found. For example, bully-victims with CVA had about 19-fold higher odds of suicidal feelings compared with uninvolved adolescents without CVA. This study, although correlational, suggested that CVA avoidance might prevent bullying involvement and suicidal feelings in adolescents.

    Full Text Available Abstract Introduction Hemoglobin Q-Iran (α75Asp→His is an important member of the hemoglobin Q family, molecularly characterized by the replacement of aspartic acid by histidine. The first report of hemoglobin Q-Iran and the nomenclature of this hemoglobinopathy dates back to 1970. Iran is known as a country with a high prevalence of α- and β-thalassemia and different types of hemoglobinopathy. Many of these variants are yet to be identified as the practice of molecular laboratory techniques is limited in this part of the world. Applying such molecular methods, we report the first hemoglobin Q-Iran cases in Northern Iran. Case presentation An unusual band was detected in an isoelectric focusing test and cellulose acetate electrophoresis of a sample from a 22-year-old Iranian man from Mazandaran Province. Capillary zone electrophoresis analysis identified this band as hemoglobin Q. A similar band was also detected in his mother's electrophoresis (38 years, Iranian ethnicity. The cases underwent molecular investigation and the presence of a hemoglobin Q-Iran mutation was confirmed by the amplification refractory mutation system polymerase chain reaction method. Direct conventional sequencing revealed a single guanine to cytosine missense mutation (c.226G > C; GAC >CAC at codon 75 in the α-globin gene in both cases. Conclusion The wide spectrum and high frequency of nondeletional α-globin mutations in Mazandaran Province is remarkable and seem to differ considerably from what has been found in Mediterranean populations. This short communication reports the first cases of patients with hemoglobin Q found in that region.

    Activation of microglial cells, the resident immune cells of the CNS causes neurotoxicity through the release of a wide array of inflammatory mediators including proinflammatory cytokines, chemokines and reactive oxygen species. In this study, we have investigated the expression of NG2 (also known as CSPG4), one of the members of transmembrane chondroitin sulfate proteoglycans family, in microglial cells and its role on inflammatory reaction of microglia by analyzing the expression of the proinflammation cytokines (interleukin-1beta (IL-1beta) and tumor necrosis factor-alpha (TNF-alpha)), chemokines (stromal cell-derived factor-1alpha and monocyte chemotactic protein-1) and inducible nitric oxide synthase (iNOS). NG2 expression was not detectable in microglial cells expressing OX-42 in the brains of 1-day old postnatal rat pups and adult rats; it was, however, induced in activated microglial cells in pups and adult rats injected with lipopolysaccharide (LPS). In vitro analysis further confirmed that LPS induced the expression of NG2 in primary microglial cells and this was inhibited by dexamethasone. It has been well demonstrated that LPS induces the expression of iNOS and proinflammatory cytokines in microglia. However in this study, LPS did not induce the mRNA expression of iNOS and cytokines including IL-1beta, and TNF-alpha in microglial cells transfected with CSPG4 siRNA. On the contrary, mRNA expression of chemokines such as monocyte chemoattractant protein-1 (MCP-1) and stromal cell-derived factor-1alpha (SDF-1alpha) was significantly increased in LPS-activated microglial cells after CSPG4 siRNA transfection in comparison with the control. The above results indicate that NG2 mediates the induction of iNOS and inflammatory cytokine expression, but not the chemokine expression in activated microglia.

    Receiving a cancer diagnosis affects family members as well as the person diagnosed. Family members often provide support for the sick person in daily life out of duty and love, and may not always think of their own vulnerability to illness. To individualise support for them, family members who are most at risk for becoming ill must be identified.The aim of this study was to investigate health-related quality of life (HRQOL) in family members of patients with advanced lung or gastrointestinal cancer 3 to 15 months after diagnosis. Data on mental and physical dimensions of HRQOL were collected from family members of these patients in this prospective quantitative study. Five assessments using the Short Form 36 Health Survey (SF-36) and EuroQol (EQ-5D) were conducted during a 1-year period starting 3 months after diagnosis. Thirty-six family members completed the study, i.e. participated in all five data collections. No statistically significant changes in physical or mental HRQOL within the study group appeared over the 1-year follow-up. Compared with norm-based scores, family members had significantly poorer mental HRQOL scores throughout the year as measured by the SF-36. Family members also scored statistically significantly worse on the EQ-5D VAS in all five assessments compared to the norm-based score. Findings showed that older family members and partners were at higher risk for decreased physical HRQOL throughout the 1-year period, and younger family members were at higher risk for poorer mental HRQOL. It is well known that ill health is associated with poor HRQOL. By identifying family members with poor HRQOL, those at risk of ill health can be identified and supported. Future large-scale research that verifies our findings is needed before making recommendations for individualised support and creating interventions best tailored to family members at risk for illness.

    Political participation and citizens' perceptions of the legitimacy and fairness of government are central components of democracy. In this article, we examine one possible threat to these markers of a just political system: family member incarceration. We offer a unique glimpse into the broader social consequences of punishment that are brought on by a partner's or parent's incarceration. We argue that the criminal justice system serves as an important institution for political socialization for the families of those imprisoned, affecting their attitudes and orientations toward the government and their will and capacity to become involved in political life. We draw from ethnographic data collected by one of the authors, quantitative data from the National Longitudinal Study of Adolescent Health, and interviews with recently released male prisoners and their female partners. Our findings suggest that experiences of a family member's incarceration complicate perceptions of government legitimacy and fairness and serve as a barrier to civic participation.

    In their study Bottke et al. (2007) suggest that a member of the Baptistina asteroid family was the probable source of the K/T impactor which ended the reign of the Dinosaurs 65 Myr ago. Knowledge of the physical and material properties pertaining to the Baptistina asteroid family are, however, not well constrained. In an effort to begin addressing the situation, data from an international collaboration of observatories were synthesized to determine the rotational period of the family's largest member, asteroid 298 Baptistina (P_r = 16.23+-0.02 hrs). Discussed here are aspects of the terrestrial impact delivery system, implications arising from the new constraints, and prospects for future work.

    This pragmatic, exploratory qualitative study, as part of a larger funded research project, sought to explore families' perspectives on what it means to value a person with dementia and how this value might influence the quality of life of people with dementia. In-depth interviews were conducted with 20 family members who used one long-term care service provider in Australia. Families described the factors influencing a positive quality of life for the person with dementia as being related to the environment and, in particular, to the resident's room, supportive staff and individualised care that valued the person's life experience. Family also reported a negative impact on quality of life when staff and the care facility neglected to provide an individualised approach. This study highlights the importance of demonstrating the value of the person with dementia, the family role and partnerships of care.

    Molybdenum (Mo) is an important trace element that is toxic at high concentrations. To resolve the mechanisms underlying Mo toxicity, Rhodobacter capsulatus mutants tolerant to high Mo concentrations were isolated by random transposon Tn5 mutagenesis. The insertion sites of six independent isolates mapped within the same gene predicted to code for a permease of unknown function located in the cytoplasmic membrane. During growth under Mo-replete conditions, the wild-type strain accumulated considerably more Mo than the permease mutant. For mutants defective for the permease, the high-affinity molybdate importer ModABC, or both transporters, in vivo Mo-dependent nitrogenase (Mo-nitrogenase) activities at different Mo concentrations suggested that ModABC and the permease import molybdate in nanomolar and micromolar ranges, respectively. Like the permease mutants, a mutant defective for ATP sulfurylase tolerated high Mo concentrations, suggesting that ATP sulfurylase is the main target of Mo inhibition in R. capsulatus. Sulfate-dependent growth of a double mutant defective for the permease and the high-affinity sulfate importer CysTWA was reduced compared to those of the single mutants, implying that the permease plays an important role in sulfate uptake. In addition, permease mutants tolerated higher tungstate and vanadate concentrations than the wild type, suggesting that the permease acts as a general oxyanion importer. We propose to call this permease PerO (for oxyanion permease). It is the first reported bacterial molybdate transporter outside the ABC transporter family.

    The Inhibitor of Growth (ING) gene family is an emerging putative type II tumor suppressor gene (TSG). Proteins of INGs (ING1-5), critical modulator of the histone code via PHD fingers, are able to suppress cell growth and proliferation, induce apoptosis, and modulate cell cycle progression. ING proteins are involved in transcriptional regulation of genes, such as the p53-inducible gene p21. ING proteins also serve as shuttling proteins between nucleus and cytoplasm, and dysregulation of this nucleocytoplasmic traffic has been shown in some cancer cells. In cancer cells, ING mRNA levels are often lost or suppressed but the genes are rarely mutated. Recently the potential roles of ING proteins as prognostic biomarkers, detection of aggressive behavior of the tumor as well as prediction of chemo-radiotherapy response have also emerged. In this review, we summarize the up-to-date knowledge on functions of the ING proteins, the protein status in human tumors and discuss as a potential target in the molecular diagnostics and therapy of cancer.

    The gaseous phytohormone ethylene regulates many developmental processes and responses to environmental conditions in higher plants.In Arabidopsis thaliana,ethylene perception and initiation of signaling are mediated by a family of five receptors which are related to prokaryotic two-component sensor histidine kinases.The transient expression of fluorescence-tagged receptors in tobacco (Nicotiana benthamiana) epidermal leaf cells demonstrated that all ethylene receptors are targeted to the ER endomembrane network and do not localize to the plasmalemma.In support of in planta overlay studies,the ethylene receptors form homomeric and heteromeric protein complexes at the ER in living plant cells,as shown by membrane recruitment assays.A comparable in vivo interaction pattern was found in the yeast mating-based split-ubiquitin system.The overlapping but distinct expression pattern of the ethylene receptor genes suggests a differential composition of the ethylene receptor complexes in different plant tissues.Our findings may have crucial functional implications on the ethylene receptor-mediated efficiency of hormone perception,induction of signaling,signal attenuation and output.

    A human member of the aldo-keto reductase (AKR) superfamily, AKR1B10, is a cytosolic NADPH-dependent reductase toward various carbonyl compounds including reactive aldehydes, and is normally expressed in intestines. The enzyme is overexpressed in several extraintestinal cancers, and suggested as a potential target for cancer treatment. We found that saturated and cis-unsaturated fatty acids inhibit AKR1B10. Among the saturated fatty acids, myristic acid was the most potent, showing the IC50 value of 4.2 μM cis-Unsaturated fatty acids inhibited AKR1B10 more potently, and linoleic, arachidonic, and docosahexaenoic acids showed the lowest IC50 values of 1.1 μM. The inhibition by these fatty acids was reversible and kinetically competitive with respect to the substrate, showing the Ki values of 0.24-1.1 μM. These fatty acids, except for α-linoleic acid, were much less inhibitory to structurally similar aldose reductase. Site-directed mutagenesis study suggested that the fatty acids interact with several active site residues of AKR1B10, of which Gln114, Val301 and Gln303 are responsible for the inhibitory selectivity. Linoleic and arachidonic acids also effectively inhibited AKR1B10-mediated 4-oxo-2-nonenal metabolism in HCT-15 cells. Thus, the cis-unsaturated fatty acids may be used as an adjuvant therapy for treatment of cancers that up-regulate AKR1B10. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available BACKGROUND: The high frequency of hemoglobinopathies in Brazil constitutes a public health problem and thus educational and preventive measures are necessary to reduce the incidence. Genetic guidance, a modality of genetic counseling, and family screening are measures that can assist in reproductive decisions and mitigate clinical, psychological and social problems of families with these disorders. OBJETIVE: The objective of the current study was to evaluate the effectiveness of educational and preventive measures for hemoglobinopathies using genetic guidance and laboratory screening of families. METHODS: The diagnoses of patients with hemoglobinopathies were confirmed and then the level of knowledge about their disease was evaluated and genetic guidance was provided. Three months later, the level of assimilated information of these patients was evaluated. In addition, laboratory diagnosis of family members was carried out. RESULTS: Diagnosis of sickle cell anemia was confirmed for most patients. Moreover, the majority of the patients who had a low level of knowledge before genetic guidance (68.8% demonstrated a higher level of assimilated information after the process (81.8%. Almost 70% of the family members had hemoglobin changes and some had hemoglobinopathies (2.6%. They were duly informed about the results of the examinations, which made it possible to investigate further. CONCLUSION: Genetic guidance and family screening were effective preventive and educational measures that improved the quality of life of patients, preventing complications and sequels and allowed the referral of those who may transmit altered genes for clinical diagnosis and to genetic counseling services.

    The cystatin-related epididymal spermatogenic (CRES) and recently identified testatin and cystatin T proteins define a new subgroup within the family 2 cystatins of cysteine protease inhibitors. Members of the CRES subgroup are predominantly expressed in reproductive tissues and lack critical cystatin active-site sequences implying divergent functions. To determine whether there are additional members of the subgroup, we searched nucleotide databases and identified two novel genes that we designated Cres2 and Cres3. These genes, like other subgroup members, encode proteins with four conserved cysteine residues and predicted molecular weights characteristic of family 2 cystatins but have divergent cystatin inhibitory sequences. Furthermore, the genes exhibited reproductive-specific expression with Cres2 exclusively expressed in the epithelial cells of the proximal and midcaput epididymal regions and Cres3 expressed in the proximal caput epididymal epithelium, Sertoli cells of the testis, and early follicles and corpora lutea in the ovary. Additional studies showed that, like Cres, both Cres2 and Cres3 genes are dependent on testicular factors for epididymal expression. Taken together, CRES2 and CRES3 represent new members of a subgroup of cystatin family 2 proteins that likely carry out tissue-specific functions distinct from that of typical cystatins.

    Janus kinase (JAK) is a family of non-receptor tyrosine kinases that participate in transducing cytokine signals from the external environment to the nucleus in various biological processes. Currently, information about their genes structure and evolutionary history has been extensively studied in mammals as well as in several fish species. By contrast, limited reports have addressed potential role of diverse JAK in signaling responses to leptin in fish. In this study, we identified and characterized five JAK members of Synechogobius hasta. Compared to mammals, more members of the JAK family were found in S. hasta, which provided evidence that the JAK family members had arisen by the whole genome duplications during vertebrate evolution. For protein structure, all of these members possessed similar domains compared with those of mammals. Their mRNAs were expressed in a wide range of tissues, but at the different levels. Incubation in vitro of freshly isolated hepatocytes of S. hasta with different concentrations of recombinant human leptin decreased the intracellular triglyceride content and lipogenic genes expression, and increased mRNA expression of several JAK and lipolytic genes. AG490, a specific inhibitor of JAK, reversed leptin-induced effects on TG content and JAK2a, JAK2b, hormone-sensitive lipase (HSL2) and acetyl-CoA carboxylase (ACCa), indicating that the JAK2a/b may have mediated the actions of leptin on lipid metabolism at transcriptional level.

    Body axes and germ layers evolve at gastrulation, and in mammals are driven by many genes; however, what orchestrates the genetic pathways during gastrulation remains elusive. Previously, we presented evidence that microRNA-17 (miRNA-17) family members, miR-17-5p, miR-20a, miR-93, and miR-106a were differentially expressed in mouse embryos and functioned to control differentiation of the stem cell population. Here, we identify function(s) that these miRNAs have during gastrulation. Fluorescent in situ hybridization miRNA probes reveal that these miRNAs are localized at the mid/posterior primitive streak (ps) in distinct populations of primitive ectoderm, mesendoderm, and mesoderm. Seven different miRNA prediction algorithms are identified in silico bone morphogenic protein receptor 2 (Bmpr2) as a target of these miRNAs. Bmpr2 is a member of the TGFβ pathway and invokes stage-specific changes during gastrulation. Recently, Bmpr2 was shown regulating cytoskeletal dynamics, cell movement, and invasion. Our previous and current data led to a hypothesis by which members of the miR-17 family influence gastrulation by suppressing Bmpr2 expression at the primitive streak. This suppression influences fate decisions of cells by affecting genes downstream of BMPR2 as well as mesoderm invasion through regulation of actin dynamics.

    Full Text Available Transglutaminase 2 (TG2 is the most widely distributed and most abundantly expressed member of the transglutaminase family of enzymes, a group of intracellular and extracellular proteins that catalyze the Ca2+-dependent posttranslational modification of proteins. It is a unique member of the transglutaminase family owing to its specialized biochemical, structural and functional elements, ubiquitous tissue distribution and subcellular localization, and substrate specificity. The broad substrate specificity of TG2 and its flexible interaction with numerous other gene products may account for its multiple biological functions. In addition to the classic Ca2+-dependent transamidation of proteins, which is a hallmark of transglutaminase enzymes, additional Ca2+-independent enzymatic and nonenzymatic activities of TG2 have been identified. Many such activities have been directly or indirectly implicated in diverse cellular physiological events, including cell growth and differentiation, cell adhesion and morphology, extracellular matrix stabilization, wound healing, cellular development, receptor-mediated endocytosis, apoptosis, and disease pathology. Given the wide range of activities of the transglutaminase gene family it has been suggested that, in the absence of active versions of TG2, its function could be compensated for by other members of the transglutaminase family. It is in the light of this assertion that we review, herein, TG2 activities and the possibilities and premises for compensation for its absence.
