    Scintillation proximity assay is a one of radioimmunoassay and can be assayed without the washing or filtration procedures normally used to separate bound from free fractions. Due to its simplicity and high-throughput protocol, it is broadly applicable to immunology, receptor binding, monitoring receptor-ligand interactions and enzyme reactions. Briefly, an antibody or receptor is coated on SPA beads. When a radiolabeled antigen or ligand binds to the beads, the SPA beads stimulate to emit short range electrons. The {sup 3}H and {sup 125}I are commonly used for radiolabeling and the produced photons are detectable with a liquid scintillation counter (LSC). A binding affinity of unlabeled ligands can be determined by competitive reaction of the radiolabeled ligands. Bevacizumab is a recombinant humanized monoclonal antibody, and can stop or delay growth of tumors by inhibiting vascular endothelial growth factor (VEGF). Bevacizumab was approved by FDA for metastatic cancer such as colorectal cancers, ovarian cancers, breast cancers and glioblastoma multiform of the brain. Recently, Dan G. duda et al. was reported that the concentration of vascular endothelial growth factor receptor-1 (VEGFR-1) in plasma may potentially be used as a negative selection biomarker. In this study, we describe a method using scintillation proximity assay to detect the amounts of VEGFR-1 protein. This method is successfully used to measure the concentration of VEGFR-1 protein in human cell extracts. In summary, a simple and sensitive assay is developed for measuring the amount of VEGFR 1 protein in cancer cell lysate using SPA beads. The antibody coating on the beads and antigen binding are achieved in one mixing step.

    The scintillation proximity assay (SPA) technology has been widely used to establish high throughput screens (HTS) for a range of targets in the pharmaceutical industry. PDE12 (aka. 2'- phosphodiesterase) has been published to participate in the degradation of oligoadenylates that are involved in the establishment of an antiviral state via the activation of ribonuclease L (RNAse-L). Degradation of oligoadenylates by PDE12 terminates these antiviral activities, leading to decreased resistance of cells for a variety of viral pathogens. Therefore inhibitors of PDE12 are discussed as antiviral therapy. Here we describe the use of the yttrium silicate SPA bead technology to assess inhibitory activity of compounds against PDE12 in a homogeneous, robust HTS feasible assay using tritiated adenosine-P-adenylate ([3H]ApA) as substrate. We found that the used [3H]ApA educt, was not able to bind to SPA beads, whereas the product [3H]AMP, as known before, was able to bind to SPA beads. This enables the measurement of PDE12 activity on [3H]ApA as a substrate using a wallac microbeta counter. This method describes a robust and high throughput capable format in terms of specificity, commonly used compound solvents, ease of detection and assay matrices. The method could facilitate the search for PDE12 inhibitors as antiviral compounds.

    Full Text Available We analyzed 93 couples undergoing male screening with the Sperm Penetration Assay (SPA before in vitro fertilization and intracytoplasmic sperm injection (ICSI, to determine the accuracy of SPA for subsequent embryonic development, incidence of pregnancy and miscarriage rates (SAB. ICSI patients with the lowest SPA scores had significantly higher incidences of Sthan did patients in the other SPA groups. Sperm quality is higher with better SPA scores. Poor sperm quality has increased incidence of chromosomal abnormalities and is associated with early fetal loss. Couples with negative SPA are candidates for preimplantation genetic diagnosis, to reduce the incidence of SAB.

    Methylation of RNA by methyltransferases is a phylogenetically ubiquitous post-transcriptional modification that occurs most extensively in transfer RNA (tRNA) and ribosomal RNA (rRNA). Biochemical characterization of RNA methyltransferase enzymes and their methylated product RNA or RNA-protein complexes is usually done by measuring the incorporation of radiolabeled methyl groups into the product over time. This has traditionally required the separation of radiolabeled product from radiolabeled methyl donor through a filter binding assay. We have adapted and optimized a scintillation proximity assay (SPA) to replace the more costly, wasteful and cumbersome filter binding assay and demonstrate its utility in studies of three distinct methyltransferases, RmtA, KsgA and ErmC'. In vitro, RmtA and KsgA methylate different bases in 16S rRNA in 30S ribosomal particles, while ErmC' most efficiently methylates protein-depleted or protein-free 23S rRNA. This assay does not utilize engineered affinity tags that are often required in SPA, and is capable of detecting either radiolabeled RNA or RNA-protein complex. We show that this method is suitable for quantitating extent of RNA methylation or active RNA methyltransferase, and for testing RNA-methyltransferase inhibitors. This assay can be carried out with techniques routinely used in a typical biochemistry laboratory or could be easily adapted for a high throughput screening format.

    The ability to detect minute amounts of specific proteins or protein modifications in blood as biomarkers for a plethora of human pathological conditions holds great promise for future medicine. Despite a large number of plausible candidate protein biomarkers published annually, the translation to clinical use is impeded by factors such as the required size of the initial studies, and limitations of the technologies used. The proximity ligation assay (PLA) is a versatile molecular tool that has the potential to address some obstacles, both in validation of biomarkers previously discovered using other techniques, and for future routine clinical diagnostic needs. The enhanced specificity of PLA extends the opportunities for large-scale, high-performance analyses of proteins. Besides advantages in the form of minimal sample consumption and an extended dynamic range, the PLA technique allows flexible assay reconfiguration. The technology can be adapted for detecting protein complexes, proximity between proteins in extracellular vesicles or in circulating tumor cells, and to address multiple post-translational modifications in the same protein molecule. We discuss herein requirements for biomarker validation, and how PLA may play an increasing role in this regard. We describe some recent developments of the technology, including proximity extension assays, the use of recombinant affinity reagents suitable for use in proximity assays, and the potential for single cell proteomics.

    The scintillation proximity assay (SPA) is a rapid radioligand binding assay. Upon binding of radioactively labeled ligands (here L-[(3)H]arginine or D-[(3)H]glucose) to acceptor proteins immobilized on fluoromicrospheres (containing the scintillant), a light signal is stimulated and measured. The application of SPA to purified, detergent-solubilized membrane transport proteins allows substrate-binding properties to be assessed (e.g., substrate specificity and affinity), usually within 1 d. Notably, the SPA makes it possible to study specific transporters without interference from other cellular components, such as endogenous transporters. Reconstitution of the target transporter into proteoliposomes is not required. The SPA procedure allows high sample throughput and simple sample handling without the need for washing or separation steps: components are mixed in one well and the signal is measured directly after incubation. Therefore, the SPA is an excellent tool for high-throughput screening experiments, e.g., to search for substrates and inhibitors, and it has also recently become an attractive tool for drug discovery.

    Full Text Available Mineral waters from Bardejovske Kupele spa are natural, strongly mineralized, with healing effects. They are classified as hydrocarbonic - containing chloride and sodium - carbonic, cold, hypotonic, with a relatively high boric acid content. Potential anti-oxidative effects of curative waters from Bardejovske Kupele were investigated against the hyaluronan (HA degradation. High-molar-mass HA was exposed to the action of ascorbate and cupric ions, which initiate free-radical chain degradation. Time-dependent changes of dynamic viscosity (h of the HA solutions were monitored by rotational viscometry. The radical scavenging capacity of curative waters was determined by the ABTS assay. Despite a significantly high content of transition metal ions, especially iron, remarkable protective effects of the two curative spa waters were found, namely Alzbeta and Klara. Even though “Alzbeta´s“ iron content was 3.5-fold higher than “Klara´s“, “Alzbeta“ was shown to have better protective properties against the HA degradation compared to “Klara“. Bolus addition of ferric ions to the reaction system instead of the natural iron-containing curative water caused a significant HA degradation. The ABTS decolorization assay revealed that the curative spa waters were proven as poorly effective scavengers of the ABTS·+ cation radical.

  8. A new scintillation proximity assay-based approach for the detection of KRAS mutations

    KRAS is very commonly mutated resulting in a constitutively activated protein, which is independent of epidermal growth factor receptor (EGFR) ligand binding and resistant to anti-EGFR therapy. Although KRAS is frequently studied, there is still no uniform standard for detecting of KRAS mutations. In this report, a new scintillation proximity assay-based approach is described that determines the relative affinities of wild-type and mutated KRAS to the anti-KRAS antibody. We performed in vitro experiments using normal human colonic cells (CCD18Co), KRAS wild type (Caco-2) and KRAS mutant (HCT 116) cell lines to determine the relative affinities of wild type or mutated KRAS toward an anti-KRAS monoclonal antibody. The process consists of two primary steps: immunoprecipitation from cell lysate to enrich the KRAS protein and the scintillation proximity assay of the immunoprecipitant to determine the relative affinity against the antibody. A fixed concentration of cell lysates was purified by the immunoprecipitation method. The expressions of the KRAS protein in all cell lines was quantitatively confirmed by western blot analysis. For the scintillation proximity assay, the KRAS standard protein was radiolabeled with {sup 125}I by a simple mixing process in the iodogen tube immediately at room temperature immediately before use. The obtained CPM (count per minute) values of were used to calculate the KRAS concentration using purified KRAS as the standard. The calculated relative affinities of 7 μg of Caco-2 and HCT 116 immunoprecipitants for the anti-KRAS antibody were 77 and 0%, respectively. The newly developed scintillation proximity assay-based strategy determines the relative affinities of wild-type or mutated KRAS towards the anti-KRAS monoclonal antibody. This determination can help distinguish mutated KRAS from the wild type protein. The new SPA based approach for detecting KRAS mutations is applicable to many other cancer-related mutations.

    The rapid influenza diagnostic tests (RIDTs) are widely distributed, simple to use, but often lack sensitivity as compared to gold standard methods (viral culture and nucleic acid detection technologies). Applying RIDTs outside of epidemic or pandemic infections results in large numbers of false negatives. Hence, a sensitive RIDT that would reduce the number of false negatives would result in an increased clinical value. We evaluated the potential of a proximity extension assay (PEA) for the detection of influenza A H1 viruses. This technology makes use of antibodies to capture the pathogen, followed by molecular detection. Forty-seven nasopharyngeal swab samples, all confirmed infections of the H1 2009 pandemic influenza virus, were evaluated. The performance of PEA was compared to the RIDT Quickvue Influenza A+B assay. The success rate of the comparative assays was modeled by means of a binary logistic response model. Both assays performed equally well within the current range of viral particles, expressed as log10 copies/ml. When the actual input of viral particles was taken into account, the 95% hitrate of PEA lies within the range of 4.60-7.02 log10 copies/reaction, which is an almost 2 log10 sensitivity improvement over the 95% hitrate of the Quickvue RIDT, ranging from 6.86 to 9.37 log10 copies/reaction. The PEA method holds promise to improve sensitive detection of influenza viruses in clinical samples. Copyright © 2013 Elsevier B.V. All rights reserved.

  12. A reusable electrochemical proximity assay for highly selective, real-time protein quantitation in biological matrices.

    Rapid and specific quantitation of a variety of proteins over a wide concentration range is highly desirable for biosensing at the point-of-care, in clinical laboratories, and in research settings. Our recently developed electrochemical proximity assay (ECPA) is a target-flexible, DNA-directed, direct-readout protein quantitation method with detection limits in the low femtomolar range, making it particularly amenable to point-of-care detection. However, consistent quantitation in more complex matrices is required at the point-of-care, and improvements in measurement speed are needed for clinical and research settings. Here, we address these concerns with a reusable ECPA, where a gentle regeneration of the surface DNA monolayer (used to capture the proximity complex) is achieved enzymatically through a novel combination of molecular biology and electrochemistry. Strategically placed uracils in the DNA sequence trigger selective cleavage of the backbone, releasing the assembled proximity complex. This allows repeated protein quantitation by square-wave voltammetry (SWV)-as quickly as 3 min between runs. The process can be repeated up to 19 times on a single electrode without loss of assay sensitivity, and currents are shown to be highly repeatable with similar calibrations using seven different electrodes. The utility of reusable ECPA is demonstrated through two important applications in complex matrices: (1) direct, quantitative monitoring of hormone secretion in real time from as few as five murine pancreatic islets and (2) standard addition experiments in unspiked serum for direct quantitation of insulin at clinically relevant levels. Results from both applications distinguish ECPA as an exceptional tool in protein quantitation.

  13. Design and validation of DNA libraries for multiplexing proximity ligation assays.

    Full Text Available Here, we present an in silico, analytical procedure for designing and testing orthogonal DNA templates for multiplexing of the proximity ligation assay (PLA. PLA is a technology for the detection of protein interactions, post-translational modifications, and protein concentrations. To enable multiplexing of the PLA, the target information of antibodies was encoded within the DNA template of a PLA, where each template comprised four single-stranded DNA molecules. Our DNA design procedure followed the principles of minimizing the free energy of DNA cross-hybridization. To validate the functionality, orthogonality, and efficiency of the constructed template libraries, we developed a high-throughput solid-phase rolling-circle amplification assay and solid-phase PLA on a microfluidic platform. Upon integration on a microfluidic chip, 640 miniaturized pull-down assays for oligonucleotides or antibodies could be performed in parallel together with steps of DNA ligation, isothermal amplification, and detection under controlled microenvironments. From a large computed PLA template library, we randomly selected 10 template sets and tested all DNA combinations for cross-reactivity in the presence and absence of antibodies. By using the microfluidic chip application, we determined rapidly the false-positive rate of the design procedure, which was less than 1%. The combined theoretical and experimental procedure is applicable for high-throughput PLA studies on a microfluidic chip.

    Virus entry into cells is a complex, multistep process that requires the coordinated activities of a large number of cellular factors and multiple membrane compartments. Because viruses can enter cells via one or more of a large number of preexisting pathways, understanding the mechanism of virus entry and transport between various intracellular compartments is a challenging task. The arrival of "omics" technologies such as genome-wide RNA interference screens has greatly advanced our ability to study the molecular intricacies of viral entry. Bioinformatics analyses of high-throughput screen data can identify enriched gene categories and specific individual genes required for infection, which can yield important insights into the cellular compartments that viruses traverse during infection. Although there are a variety of well-established genetic and biochemical approaches to validate genome-wide screen findings, confirmation of phenotypes obtained from RNA interference studies remains an important challenge. Imaging techniques commonly used to visualize virus localization to cellular organelles are often prone to artifacts that result from the necessity of using a high multiplicity of infection. Fortunately, recent advances in microscopy-based methods for studying protein location have improved our ability to accurately pinpoint virus localization within its host cell. Here we describe in detail one such technique-the proximity ligation assay (PLA)-as a tool to validate findings from a genome-wide loss-of-function genetic screen. In addition, we discuss a number of important considerations for the utilization of immunofluorescence microscopy and RNA interference to investigate the molecular mechanisms of virus entry.

    Potassium monopersulfate (MPS) is widely used in spa and pool "shock" treatments, yet contact dermatitis associated with MPS has been rarely reported. A patient presented with a generalized scattered dermatitis from the neck down that worsened after spa use. Patch testing elicited a ++ reaction to ammonium persulfate. Contact with ammonium persulfate was ruled out; however, MPS, which can cross-react with ammonium persulfate, was found to be the active ingredient in the patient's spa shock treatments. The dermatitis cleared after the patient switched to a hydrogen peroxide-based shock treatment.

    Full Text Available The diagnosis of malignant melanoma currently relies on clinical inspection of the skin surface and on the histopathological status of the excised tumor. The serum marker S100B is used for prognostic estimates at later stages of the disease, but analyses are marred by false positives and inadequate sensitivity in predicting relapsing disorder.To investigate SOX10 as a potential biomarker for melanoma and vitiligo.In this study we have applied proximity ligation assay (PLA to detect the transcription factor SOX10 as a possible serum marker for melanoma. We studied a cohort of 110 melanoma patients. We further investigated a second cohort of 85 patients with vitiligo, which is a disease that also affects melanocytes.The specificity of the SOX10 assay in serum was high, with only 1% of healthy blood donors being positive. In contrast, elevated serum SOX10 was found with high frequency among vitiligo and melanoma patients. In patients with metastases, lack of SOX10 detection was associated with treatment benefit. In two responding patients, a change from SOX10 positivity to undetectable levels was seen before the response was evident clinically.We show for the first time that SOX10 represents a promising new serum melanoma marker for detection of early stage disease, complementing the established S100B marker. Our findings imply that SOX10 can be used to monitor responses to treatment and to assess if the treatment is of benefit at stages earlier than what is possible radiologically.

    2013-10-01

    Full Text Available We have shown previously that the raft-associated proteins flotillin-1 and -2 are rapidly recruited to the uropods of chemoattractant-stimulated human neutrophils and T-cells and are involved in cell polarization. Other proteins such as the adhesion receptor PSGL-1, the actin-membrane linker proteins ezrin/radixin/moesin (ERM and the signaling enzyme phosphatidylinositol-4-phosphate 5-kinase type Iγ90 (PIPKIγ90 also accumulate in the T-cell uropod. Using the in situ proximity ligation assay (PLA we now have investigated putative close associations of these proteins in human freshly isolated T-cells before and after chemokine addition. The PLA allows in situ subcellular localization of close proximity of endogenous proteins at single-molecule resolution in fixed cells. It allows detection also of weaker and transient complexes that would not be revealed with co-immunoprecipitation approaches. We previously provided evidence for heterodimer formation of tagged flotillin-1 and -2 in T-cells before and after chemokine addition using fluorescence resonance energy transfer (FRET. We now confirm these findings using PLA for the endogenous flotillins in fixed human T-cells. Moreover, in agreement with the literature, our PLA findings confirm a close association of endogenous PSGL-1 and ERM proteins both in resting and chemokine-activated human T-cells. In addition, we provide novel evidence using the PLA for close associations of endogenous activated ERM proteins with PIPKIγ90 and of endogenous flotillins with PSGL-1 in human T-cells, before and after chemokine addition. Our findings suggest that preformed clusters of these proteins coalesce in the uropod upon cell stimulation.

    NASA's environment mirrors the changes taking place in the nation at large, i.e. workers are being asked to do more work with fewer resources. For software developers at NASA's Goddard Space Flight Center (GSFC), the effects of this change are that we must continue to produce quality code that is maintainable and reusable, but we must learn to produce it more efficiently and less expensively. To accomplish this goal, the Data Systems Technology Division (DSTD) at GSFC is trying a variety of both proven and state-of-the-art techniques for software development (e.g., object-oriented design, prototyping, designing for reuse, etc.). In order to evaluate the effectiveness of these techniques, the Software Process Assessment (SPA) program was initiated. SPA was begun under the assumption that the effects of different software development processes, techniques, and tools, on the resulting product must be evaluated in an objective manner in order to assess any benefits that may have accrued. SPA involves the collection and analysis of software product and process data. These data include metrics such as effort, code changes, size, complexity, and code readability. This paper describes the SPA data collection and analysis methodology and presents examples of benefits realized thus far by DSTD's software developers and managers.

  5. In situ proximity ligation assays indicate that hemochromatosis proteins Hfe and transferrin receptor 2 (Tfr2) do not interact.

    2013-01-01

    The hemochromatosis associated proteins HFE and Transferrin Receptor 2 (TFR2) have been shown to be important for the proper regulation of hepcidin. A number of in vitro studies using transient overexpression systems have suggested that an interaction between HFE and TFR2 is required for the regulation of hepcidin. This model of iron sensing which centers upon the requirement for an interaction between HFE and TFR2 has recently been questioned with in vivo studies in mice from our laboratory and others which suggest that Hfe and Tfr2 can regulate hepcidin independently of each other. To re-examine the postulated interaction between Hfe and Tfr2 we developed a novel expression system in which both proteins are stably co-expressed and used the proximity ligation assay to examine the interactions between Hfe, Tfr1 and Tfr2 at a cellular level. We were able to detect the previously described interaction between Hfe and Tfr1, and heterodimers between Tfr1 and Tfr2; however no interaction between Hfe and Tfr2 was observed in our system. The results from this study indicate that Hfe and Tfr2 do not interact with each other when they are stably expressed at similar levels. Furthermore, these results support in vivo studies which suggest that Hfe and Tfr2 can independently regulate hepcidin.

    Lactobacillus rhamnosus GG (LGG) is a well-established probiotic strain. The beneficial properties of this strain are partially dependent on its prolonged residence in the gastrointestinal tract, and are likely influenced by its adhesion to the intestinal mucosa. The pilin SpaC subunit, located within the Spa pili structure, is the most well studied LGG adhesion factor. However, the binding epitopes of SpaC remain largely unknown. The aim of this study was to evaluate the binding properties of SpaC to the carbohydrate moieties of intestinal glycoconjugates using a recombinant SpaC protein. In a competitive enzyme-linked immunosorbent assay, SpaC binding was markedly reduced by addition of purified mucin and the mucin oligosaccharide fraction. Histochemical staining revealed that the binding of SpaC was drastically reduced by periodic acid treatment. Moreover, in the surface plasmon resonance-based Biacore assay, SpaC bound strongly to the carbohydrate moieties containing β-galactoside at the non-reducing terminus of glycolipids. We here provide the first demonstration that SpaC binds to the oligosaccharide chains of mucins, and that the carbohydrate moieties containing β-galactoside at the non-reducing termini of glycoconjugates play a crucial role in this binding. Our results demonstrate the importance of carbohydrates of SpaC for mucus interactions. © 2015 Japanese Society of Animal Science.

  8. Luciferase reporter gene assay on human, murine and rat histamine H4 receptor orthologs: correlations and discrepancies between distal and proximal readouts.

    Full Text Available The investigation of the (pathophysiological role of the histamine H4 receptor (H4R and its validation as a possible drug target in translational animal models are compromised by distinct species-dependent discrepancies regarding potencies and receptor subtype selectivities of the pharmacological tools. Such differences were extremely pronounced in case of proximal readouts, e. g. [(32P]GTPase or [(35S]GTPγS binding assays. To improve the predictability of in vitro investigations, the aim of this study was to establish a reporter gene assay for human, murine and rat H4Rs, using bioluminescence as a more distal readout. For this purpose a cAMP responsive element (CRE controlled luciferase reporter gene assay was established in HEK293T cells, stably expressing the human (h, the mouse (m or the rat (r H4R. The potencies and efficacies of 23 selected ligands (agonists, inverse agonists and antagonists were determined and compared with the results obtained from proximal readouts. The potencies of the examined ligands at the human H4R were consistent with reported data from [(32P]GTPase or [(35S]GTPγS binding assays, despite a tendency toward increased intrinsic efficacies of partial agonists. The differences in potencies of individual agonists at the three H4R orthologs were generally less pronounced compared to more proximal readouts. In conclusion, the established reporter gene assay is highly sensitive and reliable. Regarding discrepancies compared to data from functional assays such as [(32P]GTPase and [(35S]GTPγS binding, the readout may reflect multifactorial causes downstream from G-protein activation, e.g. activation/amplification of or cross-talk between different signaling pathways.

    Small-molecule inhibitors of HIV integrase (HIV IN) have emerged as a promising new class of antivirals for the treatment of HIV/AIDS. The compounds currently approved or in clinical development specifically target HIV DNA integration and were identified using strand-transfer assays targeting the HIV IN/viral DNA complex. The authors have developed a second biochemical assay for identification of HIV integrase inhibitors, targeting the interaction between HIV IN and the cellular cofactor LEDGF/p75. They developed a luminescent proximity assay (AlphaScreen) designed to measure the association of the 80-amino-acid integrase binding domain of LEDGF/p75 with the 163-amino-acid catalytic core domain of HIV IN. This assay proved to be quite robust (with a Z' factor of 0.84 in screening libraries arrayed as orthogonal mixtures) and successfully identified several compounds specific for this protein-protein interaction.

    Methicillin-resistant Staphylococcus aureus is one of the most significant pathogens associated with health care. For efficient surveillance, control and outbreak investigation, S. aureus typing is essential. A high resolution melting curve analysis was developed and evaluated for rapid identification of the most frequent spa types found in an Austrian hospital consortium covering 2,435 beds. Among 557 methicillin-resistant Staphylococcus aureus isolates 38 different spa types were identified by sequence analysis of the hypervariable region X of the protein A gene (spa). Identification of spa types through their characteristic high resolution melting curve profiles was considerably improved by double spiking with genomic DNA from spa type t030 and spa type t003 and allowed unambiguous and fast identification of the ten most frequent spa types t001 (58%), t003 (12%), t190 (9%), t041 (5%), t022 (2%), t032 (2%), t008 (2%), t002 (1%), t5712 (1%) and t2203 (1%), representing 93% of all isolates within this hospital consortium. The performance of the assay was evaluated by testing samples with unknown spa types from the daily routine and by testing three different high resolution melting curve analysis real-time PCR instruments. The ten most frequent spa types were identified from all samples and on all instruments with 100% specificity and 100% sensitivity. Compared to classical spa typing by sequence analysis, this gene scanning assay is faster, cheaper and can be performed in a single closed tube assay format. Therefore it is an optimal screening tool to detect the most frequent endemic spa types and to exclude non-endemic spa types within a hospital.

    The type III secretion apparatus (T3SA) is a central virulence factor of many Gram-negative bacteria. Its overall morphology consists of a cytoplasmic region, inner- and outer-membrane sections and an extracellular needle. In Shigella, the length of the needle is regulated by Spa32. To understand better the role of Spa32 we searched for its interacting partners using a two-hybrid screen in yeast. We found that Spa32 interacts with the 33 C-terminal residues (CC*) of Spa40, a member of the conserved FlhB/YscU family. Using a GST pull-down assay we confirmed this interaction and identified additional interactions between Spa40 and the type III secretion components Spa33, Spa47, MxiK, MxiN and MxiA. Inactivation of spa40 abolished protein secretion and led to needleless structures. Genetic and functional analyses were used to investigate the roles of residues L310 and V320, located within the CC* domain of Spa40, in the assembly of the T3SA. Spa40 cleavage, at the conserved NPTH motif, is required for assembly of the T3SA and for its interaction with Spa32, Spa33 and Spa47. In contrast, unprocessed forms of Spa40 interacted only with MxiA, MxiK and MxiN. Our data suggest that the conformation of the cytoplasmic domain of Spa40 defines the multi-step assembly process of the T3SA.

    The development of small molecule and antibody inhibitors targeting the interaction of receptor tyrosine kinases (RTKs), such as epidermal growth factor receptor (EGFR), is of high pharmacological and biological interest. Unfortunately, conventional biochemical techniques using cell or tissue lysates and co-immunoprecipitation experiments to investigate EGFR dimerization are not always conclusive. Here we describe a series of technical and biological validation experiments demonstrating the utility of a proximity ligation assay (PLA)-based methodology for in situ visualization and quantification of ligand-dependent EGFR receptor dimerization in intact cells. Using the PLA approach combined with a universally applicable epitope tagging strategy, we detected EGFR dimers in cells transiently co-expressing FLAG-tagged and MYC-tagged human EGFRs. Our data strongly suggest that PLA can be used to detect ligand-dependent EGFR dimerization and this signal is generated in a protein interaction-based manner, rather than solely due to proximity of target proteins. This application represents a generalized RTK expression strategy for protein-interaction analysis in a transient expression system where antibody epitopes are not known or not unique enough to discriminate between interaction partners. This assay also holds promise as a general RTK dimerization screening tool in tissue specimens to identify potential dimerization inhibitors with clinical relevance.

    This unit provides a guide and detailed protocol for studying membrane protein-protein interactions (PPI) using the acceptor-sensitized Förster resonance electron transfer (FRET) method in combination with the proximity ligation assay (PLA). The protocol in this unit is focused on the preparation of FRET-PLA samples and the detection of correlative FRET/PLA signals as well as on the analysis of FRET-PLA data and interpretation of correlative results when using cyan fluorescent protein (CFP) as a FRET donor and yellow fluorescent protein (YFP) as a FRET acceptor. The correlative application of FRET and PLA combines two powerful tools for monitoring PPI, yielding results that are more reliable than with either technique alone. © 2016 by John Wiley & Sons, Inc.

    The aim of this study was to investigate the effect of various classes of clinically relevant antibiotics at sub-lethal concentrations on virulence gene expression and biofilm formation in Staphylococcus aureus. LacZ promoter fusions of genes related to staphylococcal virulence were used to monitor the effects of antibiotics on gene expression in a disc diffusion assay. The selected genes were hla and spa encoding α-hemolysin and Protein A, respectively and RNAIII, the effector molecule of the agr quorum sensing system. The results were confirmed by quantitative real-time PCR. Additionally, we monitored the effect of subinhibitory concentrations of antibiotics on the ability of S. aureus to form biofilm in a microtiter plate assay. The results show that sub-lethal antibiotic concentrations diversely modulate expression of RNAIII, hla and spa. Consistently, expression of all three genes were repressed by aminoglycosides and induced by fluoroquinolones and penicillins. In contrast, the β-lactam sub-group cephalosporins enhanced expression of RNAIII and hla but diversely affected expression of spa. The compounds cefalotin, cefamandole, cefoxitin, ceftazidime and cefixine were found to up-regulate spa, while down-regulation was observed for cefuroxime, cefotaxime and cefepime. Interestingly, biofilm assays demonstrated that the spa-inducing cefalotin resulted in less biofilm formation compared to the spa-repressing cefotaxime. We find that independently of the cephalosporin generation, cephalosporins oppositely regulate spa expression and biofilm formation. Repression of spa expression correlates with the presence of a distinct methyloxime group while induction correlates with an acidic substituted oxime group. As cephalosporines target the cell wall penicillin binding proteins we speculate that subtle differences in this interaction fine-tunes spa expression independently of agr.

    This study aimed to investigate the prevalence of Simkania negevensis in the chlorinated water of spa swimming pools and domestic network systems. A total of 10 and 36 samples were collected from two domestic water supplies and four spa facilities, respectively. Simkania negevensis was isolated in Acanthamoeba castellanii monolayers and detected by Gimenez staining and immunofluorescence test. Simkania negevensis DNA, extracted from the positive samples, was confirmed by a nested PCR assay followed by sequencing. Simkania negevensis was detected in 41·3% of samples (domestic water: 50%; untreated spa supply water: 25%; chlorinated spa pool water: 42·9%) from all the examined water systems in successive samplings performed in 1 year. The presence of S. negevensis was not correlated with the counts of Heterotrophic Bacteria and Pseudomonas aeruginosa. Unlike Legionella spp., which were never isolated from the swimming-pool water samples, S. negevensis was also detected in chlorinated spa water. This investigation shows that Simkania is widespread in natural and man-made aquatic environments, which may represent possible sources of infection: in the swimming pools, in particular, the aerosol generated by the water movement could increase the risk of inhalation of infected particles. This study represents the first evidence of the presence of S. negevensis in spa pool water. Sero-epidemiological surveys on spa users could help to clarify its transmission in this environment. © 2015 The Society for Applied Microbiology.

    2011-04-01

    This paper is about the changing shape of health tourism in a Czech spa town. The research focuses on balneotherapy as a traditional Czech healing technique, which involves complex drinking and bathing therapies, as it is increasingly being incorporated into the development of a Czech health tourism industry. Today, the health tourism industry in Mariánske Lázne is attempting to 'harmoniously' combine three elements--balneology, travel and business activities. One detects subtle shifts and consequent incongruities as doctors struggle for control over the medical portion of spa hotels. At the same time, marketing groups are creating new packages for a general clientele, and the implementation of these new packages de-medicalizes balneotherapy. Related to the issue of the doctor's authority in the spa, the changes occurring with the privatization of tourism entails the entrance of 'tourists' to Mariánske Lázne who are not necessarily seeking spa treatment but who are still staying at spa hotels. There is a general consensus among spa doctors and employees that balneotherapy has become commodified. Thus, while balneotherapy remains a traditional form of therapy, the commercial context in which it exists has created a new form of health tourism.

    Hypospadias results from abnormal development of the penis that leaves the urethral meatus proximal to its normal glanular position. Meatal position may be located anywhere along the penile shaft, but more severe forms of hypospadias may have a urethral meatus located at the scrotum or perineum. The spectrum of abnormalities may also include ventral curvature of the penis, a dorsally redundant prepuce, and atrophic corpus spongiosum. Due to the severity of these abnormalities, proximal hypospadias often requires more extensive reconstruction in order to achieve an anatomically and functionally successful result. We review the spectrum of proximal hypospadias etiology, presentation, correction, and possible associated complications. PMID:21516286

    The genetic distribution of invasive methicillin-susceptible (MSSA) and resistant S. aureus (MRSA) strains has to be addressed in order to target infection control strategies. A large MRSA epidemic caused by a certain MRSA strain (spa type 067) broke out in 2001 in our health district. We wanted to investigate the current spa type distribution in MRSA and MSSA bacteremias and assess the potential association of spa clonal complexes (spaCC) with the clinical characteristics of S. aureus bacteremia. One hundred nine invasive MRSA isolates and 353 invasive MSSA isolates were spa typed and grouped into clonal complexes (spaCC). Spa type distribution was compared to that of colonizing MRSA strains. Spa type and spaCC data linked to clinical information on the course of bacteremic cases was used to search for differences in virulence between strains. Spa type distribution in MRSA is less heterogenic than in MSSA. t067 dominates both in MRSA colonisations and in invasive findings. Among MSSA, no such dominating strains were found. Of spaCCs, mortality was the highest in spaCC 067 (25.6%). SpaCC 008 was more often associated with endocarditis than other CCs (22.7 vs 5.8%, p = 0.013), spaCC 2133 with skin infections (68.4 vs 36.4%, p = 0.007), and spaCC 012 with foreign body infections (25.0 vs 9.3%, p = 0.029) than other clonal complexes. A single successful strain can explain the major proportion of MRSA among S. aureus bacteremias. Certain spaCCs showed association with certain clinical characteristics. These findings suggest that S. aureus strains differ in their virulence and invasiveness.

  8. Insulin utilizes the PI 3-kinase pathway to inhibit SP-A gene expression in lung epithelial cells

    Directory of Open Access Journals (Sweden)

    Snyder Jeanne M

    2002-10-01

    Full Text Available Abstract Background It has been proposed that high insulin levels may cause delayed lung development in the fetuses of diabetic mothers. A key event in lung development is the production of adequate amounts of pulmonary surfactant. Insulin inhibits the expression of surfactant protein A (SP-A, the major surfactant-associated protein, in lung epithelial cells. In the present study, we investigated the signal transduction pathways involved in insulin inhibition of SP-A gene expression. Methods H441 cells, a human lung adenocarcinoma cell line, or human fetal lung explants were incubated with or without insulin. Transcription run-on assays were used to determine SP-A gene transcription rates. Northern blot analysis was used to examine the effect of various signal transduction inhibitors on SP-A gene expression. Immunoblot analysis was used to evaluate the levels and phosphorylation states of signal transduction protein kinases. Results Insulin decreased SP-A gene transcription in human lung epithelial cells within 1 hour. Insulin did not affect p44/42 mitogen-activated protein kinase (MAPK phosphorylation and the insulin inhibition of SP-A mRNA levels was not affected by PD98059, an inhibitor of the p44/42 MAPK pathway. In contrast, insulin increased p70 S6 kinase Thr389 phosphorylation within 15 minutes. Wortmannin or LY294002, both inhibitors of phosphatidylinositol 3-kinase (PI 3-kinase, or rapamycin, an inhibitor of the activation of p70 S6 kinase, a downstream effector in the PI 3-kinase pathway, abolished or attenuated the insulin-induced inhibition of SP-A mRNA levels. Conclusion Insulin inhibition of SP-A gene expression in lung epithelial cells probably occurs via the rapamycin-sensitive PI 3-kinase signaling pathway.

  9. SPA Proteins Affect the Subcellular Localization of COP1 in the COP1/SPA Ubiquitin Ligase Complex during Photomorphogenesis.

    The Arabidopsis ( Arabidopsis thaliana ) COP1/SPA ubiquitin ligase is a central repressor that suppresses light signaling in darkness by targeting positive regulators of the light response, mainly transcription factors, for degradation. Light inactivates COP1/SPA, in part by excluding COP1 from the nucleus. SPA proteins are essential cofactors of COP1, but their exact role in the COP1/SPA complex is thus far unknown. To unravel a potential role of SPA proteins in COP1 nucleocytoplasmic partitioning, we monitored the subcellular localization of COP1 in a spa1234 quadruple mutant ( spaQn ). We analyzed a YFP-COP1-expressing transgenic line and endogenous COP1 after subcellular fractionation. In dark-grown seedlings, both YFP-COP1 and endogenous COP1 accumulated in the nucleus in the absence and presence of SPA proteins, indicating that SPA proteins are not required for nuclear localization of COP1 in darkness. In contrast, in white light-grown seedlings, spaQn mutants failed to relocalize COP1 from the nucleus to the cytoplasm. Hence, SPA proteins are necessary for the light-controlled change in COP1 subcellular localization. We conclude that SPA proteins have a dual role: (1) they are required for light-responsiveness of COP1 subcellular localization, and (2) they promote COP1 activity in darkness in a fashion that is independent of the nuclear import/nuclear retention of COP1. © 2017 American Society of Plant Biologists.

    Pesticide residue in fruits & vegetables is one of the key issues affecting the export of rural products in India. Pesticide exposure or intake causes major nervous system problems in children. The solutions to quantitate them in field are rare and the pesticide residue detection in the parts per billion (ppb) ranges is challenging. Except ELISA, none of the existing methods can detect pesticide residues in ppb range in the field. We employed a new approach of concentrating field samples and used sodium polyacrylate (SPA) as water absorbing material. The SPA beads concentrate the field samples and obtained a sub ppb range detection using an existing FPIA system and could improve overall sensitivity by 10-100 fold. The developed assay can be done in few seconds. We have used three pesticides 2,4-D, atrazine and methyl parathion with 0.1, 0.5 and 3 ppb detection limit respectively. We developed a simple field ready FPIA device and used sodium poly acrylate (SPA) in this biochemical FPIA to enhance sensitivity. Our tests with spiked field samples offers a possibility of using SPA concentration assisted FPIA in field. This study will have far reaching applications of both qualitative & quantitative analysis chemical analytes in field samples.

In the present in vitro study, we compared the effect of culture media supplemented with (a) thermal spa waters (La Roche-Posay, Avène) and (b) two natural mineral drinking waters (Heppinger, Adelholzener) on physiological parameters in HaCaT keratinocytes. The different medium preparations were investigated with regard to cell proliferation and cell damage. Moreover, the impact on inflammation parameters with and without ultraviolet B (UVB) irradiation was examined. Two popular thermal spring waters were found to suppress cell proliferation and cell damage. Moreover, these waters reversed the induction of interleukin-6, as measured using enzyme-linked immunosorbent assay and promoter transactivation, and the formation of reactive oxygen species after UVB stimulation. Of note, the two natural mineral waters, which are distributed as drinking waters, had some effect on the above-mentioned parameters but to a lesser extent. In summary, our results show that spa waters, and particularly those derived from thermal springs, reduce parameters associated with inflammation. It seems likely that trace elements such as selenium and zinc are critical for the observed effects.

    Full Text Available A comprehensive analysis of physicochemical parameters in geothermal waters from the sites in Sijarinska spa (drill hole B-4 and Vranjska spa (drill hole VG-2 in order to investigate their tendency to form deposits in the pipe installation is presented. Drill holes B-4/VG-2 posses utilization capacity of 30/27 L s-1 with water temperatures 75/90 oC. VG-2 water does not show any tendency to (or shows very small sedimentation compared to the B4 water. The behaviour of the geothermal water from the B-4 hole was examined in real condition in Sijarinska spa, by letting it flow through the pipe installation. The results of geochemical analysis of water B-4 show that aragonite is the predominant mineral in the sediment (98 % with lesser amount of calcite, vaterite and anhydrite.

    Full Text Available The paper treats the area of Jodna spa in Novi Sad, which largely coincides with Futoški park, making with it the indissoluble unity. The main problem in the functioning of the Jodna psa is the fact that in legal sense Jodna spa does not exists, and in spatial sense there are still all of its content. The case of the paper is Jodna spa area, which includes the Special Hospital for Rheumatic Diseases, Hotel 'Park', Sports Center 'Sajmište' and Futoški park, which integrate them. The question of the Jodna spa planning, as well as the modern city recreation, spa and tourist center, is the goal of this paper. For this purpose it was necessary to show the historical background of the development of Jodna spa, to make the assessment of the state, critically analyze spatial plans which treat it and provide concrete suggestions for its design and equipping.

    Full Text Available Apart from very contaminated spatial areas, there are places with attractive and non-polluted environment, that are suitable for tourism and recreation. Such places are spa resorts, characterized by numerous and various natural elements having significant health and recreative functions (thermo-mineral springs, rare gases, favorable climatic conditions, rich vegetation, etc., which attract attention of ample tourist demand. Serbia is welknown as a 'country of spa resorts', because of a great number of thermo-mineral springs, long tradition and their significance for tourism economy. Official statistical service keeps records of tourist flows only at 30 spa resorts (approximately, having participation at 95% of the total tourist trade in Serbia's spas. The topic of this paper is devoted to estimation of the present state and perspectives of spa tourism in Serbia. Special attention is focused on: analysis of resources for spa tourism, discussion of key factors for tourist valorization of Serbia's spas, investigation of structural features of spa tourism, comparison of Serbia's experiences in domain of spa tourism with contemporary trends in certain spa resorts in other European countries, and, finally, defining the most important tasks for spa tourism improvement.

    The ability to adhere to enterocytes is one of the key features of probiotics. This process involves a number of factors, among which the important role of pili was demonstrated. Some Lactobacillus species are confirmed to have heterotrimeric spaCBA type pili. The aim of this study was to identify spaCBA pili in strains of selected Lactobacillus spp. and assess the impact of their presence and sequence polymorphism on the adhesion of these strains to enterocytes. Total 20 bacterial strains of L. rhamnosus, L. casei and L. paracasei were tested. The presence of pilus specific proteins coding genes spaA, spaB and spaC was verified by PCR in order to identify the presence of sequence polymorphism in the genes possibly affecting the structure of the spaCBA pilus. To correlate spaCBA polymorphism to adhesion capability the adhesion assay was carried out using Caco-2 cell line. The effectiveness of the adhesion was measured using a scintillation counter. The Lactobacillus strains analyzed showed the adhesion to Caco-2 enterocytes capability from 0.6% to 19.6%. The presence of spaCBA pili is a factor increasing the adhesion efficiency of Lactobacillus spp. to Caco-2 enterocytes. Lack of these structures on the surface of bacterial cells results in the reduction in adhesion efficiency, indicating its important role in the adhesion process. But not in all cases the correlation between the presence of protein spaCBA structures and adhesion efficiency was observed, what may indicate the important role of other factors in adhesion of analyzed strains to Caco-2 cells.

    Insulin-like growth factor binding protein (IGFBP)-1 influences fetal growth by modifying insulin-like growth factor-I (IGF-I) bioavailability. IGFBP-1 phosphorylation, which markedly increases its affinity for IGF-I, is regulated by mechanistic target of rapamycin (mTOR) and casein kinase (CSNK)-2. However, the underlying molecular mechanisms remain unknown. We examined the cellular localization and potential interactions of IGFBP-1, CSNK-2β, and mTOR as a prerequisite for protein-protein interaction. Analysis of dual immunofluorescence images indicated a potential perinuclear co-localization between IGFBP-1 and CSNK-2β and a nuclear co-localization between CSNK-2β and mTOR. Proximity ligation assay (PLA) indicated proximity between IGFBP-1 and CSNK-2β as well as mTOR and CSNK-2β but not between mTOR and IGFBP-1. Three-dimensional rendering of the PLA images validated that IGFBP-1 and CSNK-2β interactions were in the perinuclear region and mTOR and CSNK-2β interactions were predominantly perinuclear rather than nuclear as indicated by mTOR and CSNK-2β co-localization. Compared with control, hypoxia and rapamycin treatment showed markedly amplified PLA signals for IGFBP-1 and CSNK-2β (approximately 18-fold, P = 0.0002). Stable isotope labeling with multiple reaction monitoring-mass spectrometry demonstrated that hypoxia and rapamycin treatment increased IGFBP-1 phosphorylation at Ser98/Ser101/Ser119/Ser174 but most considerably (106-fold) at Ser169. We report interactions between CSNK-2β and IGFBP-1 as well as mTOR and CSNK-2β, providing strong evidence of a mechanistic link between mTOR and IGF-I signaling, two critical regulators of cell growth via CSNK-2.

    The paper presents the results of indoor radon concentration survey in 201 homes and offices in Niska Banja (the Spa of Nis), a well-known health resort and a spa in the South-East of Serbia. Radon indoor concentrations were determined by active charcoal method, according to standard EPA procedure. The indoor radon concentrations were in the range of up to 200 Bq/m(3) (47%), from 200-600 Bq/m(3) (26%) and over 600 Bq/m(3) (27%). Three areas of extremely high average radon concentrations were found (1,340-4,340 Bq/m(3)), with a maximum above 13,000 Bq/m(3). The content of natural radionuclides ((226)Ra, (214)Pb, (214)Bi, (235)U, (228)Ac, (212)Pb, (212)Bi, (208)Tl, (40)K) and (137)Cs, as well as the content of total uranium, thorium and potassium in mud used in peloidotherapy in the Health Institute "Niska Banja" was determined, too. The activities of the radionuclides were determined on an HPGe detector, by standard gamma spectroscopy. The results indicated considerably high amounts of total uranium and thorium (0.021 g/kg mud and 0.003 g/kg mud, respectively), due to the karsts origin of the soil.

  3. SPA face lift: SMAS plication-anchoring.

    Mottura, A Aldo

    2011-08-01

    A variation of the superficial musculoaponeurotic system (SMAS) plication called SPA face lift is here described. An axial line and then two medial and lateral parallel lines are penciled on the skin from the lateral canthus to the earlobe to show the future plication area. The undermining zone is delimited 1 cm beyond the medial line. In face- and neck-lifting, such marks extend vertically to the neck. Once the skin is undermined up to the delimiting marks, the three lines are penciled again on the fat layer, and a running lock suture is used for plication, with big superficial bites between the two distal lines. In fatty faces, a strip of fat is removed along the axial line to avoid bulging that can be seen through the skin. Because the undermining is limited, minor swelling occurs, and the postoperative recovery is shorter and faster. The same three lines can be marked in the contralateral side or can differ in cases of asymmetry. This report describes 244 face-lifts without any facial nerve problems. The author managed five hematoma cases in which surgery to the neck was performed. Three patients had to be touched up for insufficient skin tension. The SPA technique is consistent and easy to learn.

    BACKGROUND: Surfactant protein A (SP-A) is synthesized in the lung and is a part of the innate immune system. The aim of this study was to evaluate the expression of SP-A in lung tissue from fetuses, infants, children and adults with special regard to sudden infant death syndrome (SIDS). METHODS......: A total of 160 cases were studied; 19 fetuses and neonates, 59 SIDS and 49 explained infant deaths below 1 year of age, 19 toddlers and 14 adults. Immunohistochemical detection of SP-A using monoclonal antibodies was performed by microscopy of lung tissue specimens collected at autopsy. A scoring system...... was developed enabling semi-quantitative estimation of staining intensity and distribution. RESULTS: SP-A was detected in the terminal bronchioles and alveolar spaces of fetuses >35 weeks gestation. The intra-alveolar SP-A expression increased in the perinatal period followed by a marked drop in infants aged...

    Radioimmunoassay (RIA) and related competitive protein-binding methods began a little over 20 years ago as a cumbersome research methodology in a few specialized laboratories. Endocrinology has been greatly enriched by the new knowledge that has come as a direct result of RIA methods. Establishment of the taxol RIA system will be expected to develop RIA for drug monitoring. Scintillation proximity assay was useful since any separation step is not required, it has the advantage of dealing with multiple samples. The increased sensitivity of the new assay in determining HCV RT([{sup 125}I]dUTP) suggests that it would be worth investigating whether the system can be applied to analysis. [{sup 125}I] lodotyramine with 98.5% radiochemical purity. Optimal background counts was certificated using varied radioactivity of radionuclides. Appropriate standard curve was obtained from SPA method successively, and the concentration of hCG from unknown serum was determined by standard curve. The result concentration of hCG from unknown serum was determined by synthesized successively and purified by HPLC system. Hybridoma reducing monoclonal anti thyroglobulin antibodies titer is measured by ELISA. These studies play an important role in development of in vitro assay with radionuclides.

    Dissemination of spa services across the globe and its market saturation drive demand for differentiated communication methods. This study aims to explore the influential factors on spa goers' repeated visits and their practical applications in the health and wellness spa industry. The identified factors were used as the measurement variables to examine the relation with spa goers' repeated visits. The proposed concept was tested by a mixed method combining a self-administered questionnaire and semistructured interview with 54 survey participants and 6 interviewees. It was meaningful to use a sample of the UK spa goers from the southwest region since global spa trends stem from the EU spas, and the United Kingdom is one of the market leaders. The data were analyzed using frequency, percentage, multiple logistic regression analysis, and coding process. The survey findings demonstrated that the most significant influential factor on the repeated spa visits is a memorable experience of which showed 13.7 times higher probability than the reference up-to-date facility. The details of memorable experiences were discovered throughout the interviews that include the rediscovery of self, feeling of connectedness, recharge for positive emotions, self-reward through escapism, and experience of noncommercialized local products and attractions. Therefore, using experiential marketing methods can be effective spa service marketing.

  9. The plant defense and pathogen counterdefense mediated by Hevea brasiliensis serine protease HbSPA and Phytophthora palmivora extracellular protease inhibitor PpEPI10.

    Directory of Open Access Journals (Sweden)

    Kitiya Ekchaweng

    Full Text Available Rubber tree (Hevea brasiliensis Muell. Arg is an important economic crop in Thailand. Leaf fall and black stripe diseases caused by the aggressive oomycete pathogen Phytophthora palmivora, cause deleterious damage on rubber tree growth leading to decrease of latex production. To gain insights into the molecular function of H. brasiliensis subtilisin-like serine proteases, the HbSPA, HbSPB, and HbSPC genes were transiently expressed in Nicotiana benthamiana via agroinfiltration. A functional protease encoded by HbSPA was successfully expressed in the apoplast of N. benthamiana leaves. Transient expression of HbSPA in N. benthamiana leaves enhanced resistance to P. palmivora, suggesting that HbSPA plays an important role in plant defense. P. palmivora Kazal-like extracellular protease inhibitor 10 (PpEPI10, an apoplastic effector, has been implicated in pathogenicity through the suppression of H. brasiliensis protease. Semi-quantitative RT-PCR revealed that the PpEPI10 gene was significantly up-regulated during colonization of rubber tree by P. palmivora. Concurrently, the HbSPA gene was highly expressed during infection. To investigate a possible interaction between HbSPA and PpEPI10, the recombinant PpEPI10 protein (rPpEPI10 was expressed in Escherichia coli and purified using affinity chromatography. In-gel zymogram and co-immunoprecipitation (co-IP assays demonstrated that rPpEPI10 specifically inhibited and interacted with HbSPA. The targeting of HbSPA by PpEPI10 revealed a defense-counterdefense mechanism, which is mediated by plant protease and pathogen protease inhibitor, in H. brasiliensis-P. palmivora interactions.

    To investigate the effect of spa adjuvant therapy on diabetic lower extremity arterial disease (LEAD). 128 patients with type II diabetes were separated into three groups according to the degree of lower extremity vascular stenosis. Patients within each group were then randomly divided to receive no treatment (control) or spa adjuvant therapy (treatment). Clinical symptoms, blood pressure and hemodynamic analyses were compared between control and treatment groups by Chi square or t-test. After adjuvant therapy with spa, patients' pain, numbness, and cold sensation were significantly improved compared with control groups (PSpa adjuvant therapy also significantly increased the dorsalis pedis pulse and systolic peak velocity ratio of patients with mild lower extremity vascular stenosis compared with control groups (P0.05). Both in the spa and control groups, there were no significant differences before and after medication for fasting, 2-h postprandial blood glucose and glycosylated hemoglobin (HbA1C) analyses (P>0.05). Spa adjuvant therapy can significantly alleviate lower extremity pain, numbness, and cold sensory symptoms in diabetic LEAD patients with stenosis. Moreover, in LEAD patients with mild stenosis, spa adjuvant therapy also improves the dorsalis pedis pulse and systolic peak velocity ratio, suggesting a potential role for spa therapy as an early intervention strategy to treat the initial stages of disease.

    Full Text Available Over the last ten years, spa as one of the products of wellness tourism is growing very fast in Bali, necessitating the development strategy in accordance with the conditions of Bali. The rapid development momentum for the business of spa is opened in Bali, although in the external side of the business will compete with the international trade environment to take advantage and create sustainable economic growth prospects. This will be an opportunity for Bali as a destination spa in the future. In an effort to maintain and continue to develop quality as the best spa destinations in the world, we need the right strategy to make the creation and supporting product innovation spa in Bali. This study aims to create an integrated assessment of the extent of the influence of the utilization of natural resources, human resources and local knowledge of the existence and essence of spa in Bali and methods for utilizing natural resources, human resources and local knowledge of Bali on development of spa in Bali. Research design and methods of approach to the problem that are done in this study using descriptive design, where the planning and execution of research conducted in the form of field data are collected in the form of surveys, questionnaires and statistical data processing. The target population in this study is divided into three, namely: the company or a place that offers spa services, spa services supporting manufacturers and both foreign and domestic tourists who use the services of spa services in Badung and Gianyar, by assuming the two districts can represent the tourist population to Bali. Based on several case studies found that the performance of spa services in terms of utilization of natural resources, human resources, and local wisdom of Bali, particularly in terms of (1 the atmosphere (ambience, (2 equipment and design, (3 the qualifications and skills of the therapist, (4 treatment menu, and (5 the quality of services as a whole has

    Surfactant protein A (SP-A) plays a role in lung innate immunity and surfactant-related functions. Two functional genes, SP-A1 (SFTPA1) and SP-A2 (SFTPA2), are present in humans and primates (rodents have one gene). Single gene SP-A1 or SP-A2 proteins expressed in vitro are functional. To study their role in vivo, we generated humanized transgenic (hTG) C57BL/6 mice, SP-A1(6A4) and SP-A2(1A3). The SP-A cDNA in experimental constructs was driven by the 3.7-kb SP-C promoter. Positive hTG mice were bred with SP-A knock-out mice to generate F8 offspring for study. Epithelial alveolar type II cells were SP-A-positive, and Clara cells were negative by immunohistochemistry in hTG mice. The levels of SP-A in lungs of two hTG lines used were comparable with those in human lungs. Southern blot analysis indicated that two cDNA copies of either SP-A1(6A4) or SP-A2(1A3) were integrated as a concatemer into the genome of each of the two hTG lines. Electron microscopy analysis revealed that hTG mice with a single SP-A1(6A4) or SP-A2(1A3) gene product lacked tubular myelin (TM), but hTG mice carrying both had TM. Furthermore, TM was observed in human bronchoalveolar lavage fluid only if both SP-A1 and SP-A2 gene products were present and not in those containing primarily (>99.7%) either SP-A1 or SP-A2 gene products. In vivo rescue study confirmed that TM can only be restored after administering exogenous SP-A containing both SP-A1 and SP-A2 into the lungs of SP-A knock-out mice. These observations indicate that SP-A1 and SP-A2 diverged functionally at least in terms of TM formation. PMID:20048345

    Staphylococcus aureus is a major human pathogen responsible for increasing the prevalence of community- and hospital-acquired infections. Protein A (SpA) is a key virulence factor of S. aureus and is highly conserved. Sequencing of the variable-number tandem-repeat region of SpA (spa typing......) provides a rapid and reliable method for epidemiological studies. Rarely, non-spa-typeable S. aureus strains are encountered. The reason for this is not known. In this study, we characterized eight non-spa-typeable bacteremia isolates. Sequencing of the entire spa locus was successful for five strains...... and revealed various mutations of spa, all of which included a deletion of immunoglobulin G binding domain C, in which the upper primer for spa typing is located, while two strains were truly spa negative. This is the first report demonstrating that nontypeability of S. aureus by spa sequencing is due either...

    The aim of this paper was to investigate beliefs and preferences towards treatment of patients with psoriasis attending Comano SPA (Trentino, Italy) in comparison to patients referring to the University Hospital of Verona. Patient with psoriasis referring to Comano SPA and to the University Hospital of Verona were visited, their clinical data were collected and they were administered a questionnaire investigating their knowledge about psoriasis, as well as their attitude and preferences towards conventional therapies and SPA treatments. [Corrected] A total of 288 patients with chronic plaque psoriasis were recruited, 169 from Comano SPA and 119 from Verona Hospital. There were no differences regarding demographic data, severity of psoriasis, impact on quality of life and prevalence of cardio-metabolic comorbidities between the two groups. SPA patients more rarely believed that pharmacological treatments are safe and effective (6.5% vs. 21.8% P=0.001), had less trust in physician (32.5% vs. 67.2%; P=0.001) and preferred alternative therapies like balneotherapy compared to hospital patients (55.6% vs. 30.3%; P=0.0001), because they assumed they were more safe and effective than systemic drugs (37.3% vs. 1.7%; P=0.001). SPA patients preferred living with psoriasis rather than taking drugs to treat it more commonly than hospital patients (26.6% vs. 5%; P=0.001). Patients attending a SPA centre tend to trust conventional drug treatments less often than those attending a hospital clinic, and prefer balneotherapy as a dedicated alternative therapy. Fear of adverse events is a major concern among patients with psoriasis, especially those attending a SPA center.

  18. MANAGEMENT AND DEVELOPMENT POSSIBILITIES FOR SPA TOURISM IN SERBIA

    2010-06-01

    Full Text Available Two forms of tourism, which are represented to a large extent in the world, are spa and wellness tourism. In Serbia, spa and wellness tourism are not sufficiently used, although there are excellent conditions. During twenty century the state was paying more attention and money on the sea and river tourism. However, the separation of Serbia and Montenegro in two independent counties had left Serbia without an entrance to the Adriatic Sea, so development of other tourist products and destinations became an imperative for survival and existence in the tourist map of Europe and the world. The paper presents the basic aims and policies of development of spa tourism in Serbia and data obtained in the survey regarding quality of services provided in some spa towns in Serbia. Based on the results to which the research occurred, authors wished to point out main activities and tasks that the state uses in creating a development strategy of spa tourism, the programs that have already been taken, so as the influence of the economic crisis to spa tourism.

    Staphylococcus aureus is a major human pathogen responsible for increasing the prevalence of community- and hospital-acquired infections. Protein A (SpA) is a key virulence factor of S. aureus and is highly conserved. Sequencing of the variable-number tandem-repeat region of SpA (spa typing......) provides a rapid and reliable method for epidemiological studies. Rarely, non-spa-typeable S. aureus strains are encountered. The reason for this is not known. In this study, we characterized eight non-spa-typeable bacteremia isolates.

    BACKGROUND: The sperm penetration assay (SPA) is used to predict the fertilizing capacity of sperm. Thus, some programs rely on SPA scores to formulate insemination plans in conjunction with in-vitro fertilization (IVF) cycles. The purpose of this study was to evaluate if a relationship exists between SPA scores and polyspermy rates during conventional IVF cycles. METHODS: A total of 1350 consecutive IVF patients using conventional IVF insemination were evaluated in the study. Oocytes were inseminated three hours post-retrieval by the addition of 150,000 to 300,000 progressively motile sperm. Approximately 18 hours after insemination, the oocytes were evaluated for fertilization by the visualization of pronuclei. The presence of three or more pronuclei was indicative of polyspermy. Polyspermy rates, fertilization success, embryo quality, and pregnancy rates were analyzed retrospectively to evaluate their relationship with SPA score, count, motility, number of progressively motile sperm inseminated, oocyte pre-insemination incubation time, patient age, and diagnosis. RESULTS: A significant positive relationship was observed between SPA score and polyspermy rate (rs = 0.10, p polyspermy rates than those with abnormal SPA scores (6.3% +/- 1.5% vs. 2.0% +/- 0.7%, p polyspermy rates and IVF fertilization percentage. Additionally, there is a slight increase in clinical pregnancy rates, and embryo implantation rates with increased SPA. Furthermore, there is a slight decrease in spontaneous abortions rates related to increased SPA.

    Full Text Available A multiset is a collection of objects in which repetition of elements is essential. This paper is an attempt to explore the theoretical aspects of multiset by extending the notions of compact, proximity relation and proximal neighborhood to the multiset context. Examples of new multiset topologies, open multiset cover, compact multiset and many identities involving the concept of multiset have been introduced. Further, an integral examples of multiset proximity relations are obtained. A multiset topology induced by a multiset proximity relation on a multiset M has been presented. Also the concept of multiset δ- neighborhood in the multiset proximity space which furnishes an alternative approach to the study of multiset proximity spaces has been mentioned. Finally, some results on this new approach have been obtained and one of the most important results is: every T4- multiset space is semi-compatible with multiset proximity relation δ on M (Theorem 5.10.

    Molecular typing is an important tool for control and prevention of infection. A suitable molecular typing method for epidemiological investigation must be easy to perform, highly reproducible, inexpensive, rapid and easy to interpret. In this study, two molecular typing methods including the conventional PCR-sequencing method and high resolution melting (HRM) analysis were used for staphylococcal protein A (spa) typing of 30 Methicillin-resistant Staphylococcus aureus (MRSA) isolates recovered from clinical samples. Based on PCR-sequencing method results, 16 different spa types were identified among the 30 MRSA isolates. Among the 16 different spa types, 14 spa types separated by HRM method. Two spa types including t4718 and t2894 were not separated from each other. According to our results, spa typing based on HRM analysis method is very rapid, easy to perform and cost-effective, but this method must be standardized for different regions, spa types, and real-time machinery.

    2011-04-01

    Full Text Available Background: Streptococcus mutans surface-protein antigen (SpaP, PAc, or antigen I/II has been well known to play an important role in initial attachment to tooth surfaces. However, strains with weak SpaP-expression were recently reported to be found in natural populations of S. mutans. The S. mutans gbpC-negative strain Z1, which we previously isolated from saliva and plaque samples, apparently expresses relatively low levels of SpaP protein compared to S. mutans strains MT8148 or UA159. Objective: To elucidate the mechanism for weak SpaP-expression in this strain, the spaP gene region in strain Z1 was amplified by polymerase chain reaction (PCR and analyzed. Methods: Allelic exchange mutants between strains Z1 and UA159 involving the spaP gene region were constructed. The SpaP protein expressed in the mutants was detected with Coomasie Brilliant Blue (CBB-staining and Western blot analysis following SDS-PAGE. Results: The 4689 bp spaP gene coding sequence for Z1 appeared to be intact. In contrast, a 20 bp nucleotide sequence appeared to be deleted from the region immediately upstream from the Z1 spaP gene when compared to the same region in UA159. The 216 bp and 237 bp intergenic fragments upstream from the spaP gene, respectively, from Z1 and UA159 were isolated, modified, and transformed into the other strain by allelic replacement. The resultant UA159-promoter region-mutant exhibited extremely weak SpaP-expression similar to that of strain Z1 and the Z1 complemented mutant expressed Spa protein levels like that of strain UA159. Conclusion: These results suggest that weak SpaP-expression in strain Z1 resulted from a 20 bp-deletion in the spaP gene promoter region.

  16. SPA- STATISTICAL PACKAGE FOR TIME AND FREQUENCY DOMAIN ANALYSIS

    Science.gov (United States)

    Brownlow, J. D.

    1994-01-01

    The need for statistical analysis often arises when data is in the form of a time series. This type of data is usually a collection of numerical observations made at specified time intervals. Two kinds of analysis may be performed on the data. First, the time series may be treated as a set of independent observations using a time domain analysis to derive the usual statistical properties including the mean, variance, and distribution form. Secondly, the order and time intervals of the observations may be used in a frequency domain analysis to examine the time series for periodicities. In almost all practical applications, the collected data is actually a mixture of the desired signal and a noise signal which is collected over a finite time period with a finite precision. Therefore, any statistical calculations and analyses are actually estimates. The Spectrum Analysis (SPA) program was developed to perform a wide range of statistical estimation functions. SPA can provide the data analyst with a rigorous tool for performing time and frequency domain studies. In a time domain statistical analysis the SPA program will compute the mean variance, standard deviation, mean square, and root mean square. It also lists the data maximum, data minimum, and the number of observations included in the sample. In addition, a histogram of the time domain data is generated, a normal curve is fit to the histogram, and a goodness-of-fit test is performed. These time domain calculations may be performed on both raw and filtered data. For a frequency domain statistical analysis the SPA program computes the power spectrum, cross spectrum, coherence, phase angle, amplitude ratio, and transfer function. The estimates of the frequency domain parameters may be smoothed with the use of Hann-Tukey, Hamming, Barlett, or moving average windows. Various digital filters are available to isolate data frequency components. Frequency components with periods longer than the data collection interval

    Pulsed-field gel electrophoresis (PFGE) is a valuable molecular typing assay used for methicillin-resistant Staphylococcus aureus (MRSA) surveillance and genotyping. However, there are several limitations associated with PFGE. In Alberta, Canada, the significant increase in the number of MRSA isolates submitted to the Provincial Laboratory for Public Health (ProvLab) for PFGE typing led to the need for an alternative genotyping method. In this study, we describe the transition from PFGE to Staphylococcus protein A (spa), Staphylococcal cassette chromosome (SCCmec), and Panton-Valentine leukocidin (PVL) typing. A total of 1915 clinical MRSA isolates collected from 2005 to 2009 were used to develop and validate an algorithm for assigning PFGE epidemic types using spa, SCCmec, and PVL typing and the resulting data was used to populate a new Alberta MRSA typing database. An additional 12620 clinical MRSA isolates collected from 2010 to 2012 as part of ongoing routine molecular testing at ProvLab were characterized using the new typing algorithm and the Alberta MRSA typing database. Switching to spa, SCCmec, and PVL from PFGE typing substantially reduced hands-on and turn-around times while maintaining historical PFGE epidemic type designations. This led to an approximate $77,000 reduction in costs from 2010 to 2012. PFGE typing is still required for a small subset of MRSA isolates that have spa types that are rare, novel, or associated with more than one PFGE epidemic type. PMID:24244440

  18. SpaK/SpaR two-component system characterized by a structure-driven domain-fusion method and in vitro phosphorylation studies.

    Directory of Open Access Journals (Sweden)

    Anu Chakicherla

    2009-06-01

    Full Text Available Here we introduce a quantitative structure-driven computational domain-fusion method, which we used to predict the structures of proteins believed to be involved in regulation of the subtilin pathway in Bacillus subtilis, and used to predict a protein-protein complex formed by interaction between the proteins. Homology modeling of SpaK and SpaR yielded preliminary structural models based on a best template for SpaK comprising a dimer of a histidine kinase, and for SpaR a response regulator protein. Our LGA code was used to identify multi-domain proteins with structure homology to both modeled structures, yielding a set of domain-fusion templates then used to model a hypothetical SpaK/SpaR complex. The models were used to identify putative functional residues and residues at the protein-protein interface, and bioinformatics was used to compare functionally and structurally relevant residues in corresponding positions among proteins with structural homology to the templates. Models of the complex were evaluated in light of known properties of the functional residues within two-component systems involving His-Asp phosphorelays. Based on this analysis, a phosphotransferase complexed with a beryllofluoride was selected as the optimal template for modeling a SpaK/SpaR complex conformation. In vitro phosphorylation studies performed using wild type and site-directed SpaK mutant proteins validated the predictions derived from application of the structure-driven domain-fusion method: SpaK was phosphorylated in the presence of (32P-ATP and the phosphate moiety was subsequently transferred to SpaR, supporting the hypothesis that SpaK and SpaR function as sensor and response regulator, respectively, in a two-component signal transduction system, and furthermore suggesting that the structure-driven domain-fusion approach correctly predicted a physical interaction between SpaK and SpaR. Our domain-fusion algorithm leverages quantitative structure information

    The use of water for medical treatment is probably as old as mankind. Until the middle of the last century, spa treatment, including hydrotherapy and balneotherapy, remained popular but went into decline especially in the Anglo-Saxon world with the development of effective analgesics. However, no analgesic, regardless of its potency, is capable of eliminating pain, and reports of life-threatening adverse reactions to the use of these drugs led to renewed interest in spa therapy. Because of methodologic difficulties and lack of research funding, the effects of 'water treatments' in the relief of pain have rarely been subjected to rigorous assessment by randomised, controlled trials. It is our opinion that the three therapeutic modalities must be considered separately, and this was done in the present paper. In addition, we review the research on the mechanism of action and cost effectiveness of such treatments and examine what research might be useful in the future.

    Phytochromes function as red/far-red photoreceptors in plants and are essential for light-regulated growth and development. Photomorphogenesis, the developmental program in light, is the default program in seed plants. In dark-grown seedlings, photomorphogenic growth is suppressed by the action of the CONSTITUTIVELY PHOTOMORPHOGENIC1 (COP1)/SUPPRESSOR OF phyA-105 (SPA) complex, which targets positive regulators of photomorphogenic growth for degradation by the proteasome. Phytochromes inhibit the COP1/SPA complex, leading to the accumulation of transcription factors promoting photomorphogenesis; yet, the mechanism by which they inactivate COP1/SPA is still unknown. Here, we show that light-activated phytochrome A (phyA) and phytochrome B (phyB) interact with SPA1 and other SPA proteins. Fluorescence resonance energy transfer-fluorescence lifetime imaging microscopy analyses show that SPAs and phytochromes colocalize and interact in nuclear bodies. Furthermore, light-activated phyA and phyB disrupt the interaction between COP1 and SPAs, resulting in reorganization of the COP1/SPA complex in planta. The light-induced stabilization of HFR1, a photomorphogenic factor targeted for degradation by COP1/SPA, correlates temporally with the accumulation of phyA in the nucleus and localization of phyA to nuclear bodies. Overall, these data provide a molecular mechanism for the inactivation of the COP1/SPA complex by phyA- and phyB-mediated light perception. © 2015 American Society of Plant Biologists.

    2016-06-01

    Osteoarthritis (OA) is a public health problem that will probably increase in the future with the aging of the population. Crenobalneotherapy is commonly used to treat OA, but evidence from previous reviews was not sufficient. This systematic review aimed to identify the best evidence for the clinical effect of crenobalneotherapy for knee OA. We systematically searched MEDLINE via PubMed, PEDRO and the Cochrane Central Register of Controlled Trials for articles published up to September 2015. Articles were included if trials were comparative, if one or more of the subgroups had knee OA with separate data, and if spa therapy or any hydrotherapy techniques involving mineral water or mineral mud was compared to any other intervention or no treatment. Statistical validity, external validity and quality of side effects assessment were evaluated by personal checklists. Risk of bias was assessed by the CLEAR NTP. Treatments (hot mineral water baths, mud therapy, hot showers, and sometimes massage and supervised water exercises) delivered in spa centers across Europe and the Middle East seem to improve symptoms in knee OA. They may be effective for pain and function. There are conflicting results about the effect on quality of life and drug consumption. Improvements with spa therapy for knee OA appear to be clinically relevant until 3 to 6 months and sometimes 9 months. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    2012-01-01

    Full Text Available Fibromyalgia syndrome (FS is a common musculoskeletal disorder characterized by otherwise unexplained chronic widespread pain, a lowered pain threshold, high tender point counts, sleep disturbances, fatigue, headache, irritable bowel syndrome, morning stiffness, paraesthesias in the extremities, often psychological distress and depressed mood. Consequently, FS has a negative impact on working capacity, family life, social functioning and quality of life. Because of unknown etiology and not clearly understood pathogenesis, there is no standard therapy regime for FS. A variety of medical treatments, including antidepressants, opioids, analgesic or non-steroidal anti-inflammatory drugs, sedatives, muscle relaxants and antiepileptics, have been used to treat FS. Currently, no pharmacological treatment for FS is consistently successful. According to recent guidelines, the optimal treatment of FS requires a multidisciplinary approach with a combination of non-pharmacological and pharmacological treatment modalities. Spa therapy is a popular treatment for FS in many European countries, as well as in Japan and Israel. However, despite their long history and popularity spa treatments are still the subject of debate and their role in modern medicine is still not clear. The objective of this review is to summarize the currently available information on clinical effects and mechanism of action of spa therapy in FS. We also provide some suggestions for further development in this area.

    The purpose of this study was to assess the quality of study reports on spa therapy based on randomized controlled trials by the spa therapy and balneotherapy checklist (SPAC), and to show the relationship between SPAC score and the characteristics of publication. We searched the following databases from 1990 up to September 30, 2013: MEDLINE via PubMed, CINAHL, Web of Science, Ichushi Web, Global Health Library, the Western Pacific Region Index Medicus, PsycINFO, and the Cochrane Database of Systematic Reviews. We used the SPAC to assess the quality of reports on spa therapy and balneotherapy trials (SPAC) that was developed using the Delphi consensus method. Fifty-one studies met all inclusion criteria. Forty studies (78%) were about "Diseases of the musculoskeletal system and connective)". The total SPAC score (full-mark; 19 pts) was 10.8 ± 2.3 pts (mean ± SD). The items for which a description was lacking (very poor; spa facility where the data were collected"; "pH"; "scale of bathtub"; "presence of other facility and exposure than bathing (sauna, steam bath, etc.)"; "qualification and experience of care provider"; "Instructions about daily life" and "adherence". We clarified that there was no relationship between the publish period, languages, and the impact factor (IF) for the SPAC score. In order to prevent flawed description, SPAC could provide indispensable information for researchers who are going to design a research protocol according to each disease.

    Recognized outbreaks of Legionnaires' disease (LD) are rare; when they occur, they provide opportunities to understand the epidemiology of the illness and improve prevention strategies. We investigated a population-based outbreak. After the confirmation of LD in October 1996 in five people in neighbouring towns in southwest Virginia, active surveillance for additional cases was undertaken. A case-control study was conducted to identify exposures associated with illness, followed by a cohort study among employees of the facility at which the source of the outbreak was located in order to assess unrecognized exposure and illness. Samples of likely sources of LD in the facility were cultured for LEGIONELLA: In all, 23 laboratory-confirmed cases of LD were eventually identified. Of the 15 cases in the case-control study, 14 (93%) reported visiting a home-improvement store, compared with 12 (27%) of 45 controls (matched odds ratio [MOR] = 23.3; 95% CI : 3-182). Among home-improvement centre patrons, 10 (77%) of 13 cases questioned recalled either visiting or walking by a display whirlpool spa, compared with 3 (25%) of 12 controls (MOR = 5.5; 95% CI : 0.7-256.0). Two cases' sputum isolates were an exact match, by monoclonal antibody subtyping and arbitrarily primed polymerase chain reaction, to a whirlpool spa filter isolate from the store. Employees reporting more exposure to the display spas were more likely to report symptoms of LD or to have an elevated titre. This investigation shows that LD can be transmitted from a whirlpool spa used for display only, and highlights the need for minimizing the risk of transmission of LD from all water-filled spas. Key messages This paper describes an investigation of a population-based outbreak of Legionnaires' disease (LD). A case-control study first identified a home-improvement store as the likely source of the outbreak. An environmental investigation later confirmed that finding, as two cases' sputum isolates were an exact

  9. Human Pulmonary Surfactant Protein SP-A1 Provides Maximal Efficiency of Lung Interfacial Films.

    Pulmonary surfactant is a lipoprotein complex that reduces surface tension to prevent alveolar collapse and contributes to the protection of the respiratory surface from the entry of pathogens. Surfactant protein A (SP-A) is a hydrophilic glycoprotein of the collectin family, and its main function is related to host defense. However, previous studies have shown that SP-A also aids in the formation and biophysical properties of pulmonary surfactant films at the air-water interface. Humans, unlike rodents, have two genes, SFTPA1 and SFTPA2. The encoded proteins, SP-A1 and SP-A2, differ quantitatively or qualitatively in function. It has been shown that both gene products are necessary for tubular myelin formation, an extracellular structural form of lung surfactant. The goal of this study was to investigate potential differences in the biophysical properties of surfactants containing human SP-A1, SP-A2, or both. For this purpose, we have studied for the first time, to our knowledge, the biophysical properties of pulmonary surfactant from individual humanized transgenic mice expressing human SP-A1, SP-A2, or both SP-A1 and SP-A2, in the captive bubble surfactometer. We observed that pulmonary surfactant containing SP-A1 reaches lower surface tension after postexpansion interfacial adsorption than surfactants containing no SP-A or only SP-A2. Under interfacial compression-expansion cycling conditions, surfactant films containing SP-A1 also performed better, particularly with respect to the reorganization of the films that takes place during compression. On the other hand, addition of recombinant SP-A1 to a surfactant preparation reconstituted from the hydrophobic fraction of a porcine surfactant made it more resistant to inhibition by serum than the addition of equivalent amounts of SP-A2. We conclude that the presence of SP-A1 allows pulmonary surfactant to adopt a particularly favorable structure with optimal biophysical properties. Copyright © 2016 Biophysical

    Very little is known about how the spa gene mutates over time in methicillin-resistant Staphylococcus aureus (MRSA) from the same patient. Copenhagen is an area with low prevalence of MRSA but with high variability in spa types. We collected 1536 MRSA isolates from 319 patients during a 5-year...... period and found spa type alterations in 30 MRSA isolates (2%) from 13 patients (4%). The alteration most often seen was the deletion of repeats followed by repeat duplication and point mutation....

    Surfactant protein A (SP-A) plays a role in lung innate immunity and surfactant-related functions. Two functional genes, SP-A1 (SFTPA1) and SP-A2 (SFTPA2), are present in humans and primates (rodents have one gene). Single gene SP-A1 or SP-A2 proteins expressed in vitro are functional. To study their role in vivo, we generated humanized transgenic (hTG) C57BL/6 mice, SP-A1(6A(4)) and SP-A2(1A(3)). The SP-A cDNA in experimental constructs was driven by the 3.7-kb SP-C promoter. Positive hTG mice were bred with SP-A knock-out mice to generate F8 offspring for study. Epithelial alveolar type II cells were SP-A-positive, and Clara cells were negative by immunohistochemistry in hTG mice. The levels of SP-A in lungs of two hTG lines used were comparable with those in human lungs. Southern blot analysis indicated that two cDNA copies of either SP-A1(6A(4)) or SP-A2(1A(3)) were integrated as a concatemer into the genome of each of the two hTG lines. Electron microscopy analysis revealed that hTG mice with a single SP-A1(6A(4)) or SP-A2(1A(3)) gene product lacked tubular myelin (TM), but hTG mice carrying both had TM. Furthermore, TM was observed in human bronchoalveolar lavage fluid only if both SP-A1 and SP-A2 gene products were present and not in those containing primarily (>99.7%) either SP-A1 or SP-A2 gene products. In vivo rescue study confirmed that TM can only be restored after administering exogenous SP-A containing both SP-A1 and SP-A2 into the lungs of SP-A knock-out mice. These observations indicate that SP-A1 and SP-A2 diverged functionally at least in terms of TM formation.

    Full Text Available Spam reviews are increasingly appearing on the Internet to promote sales or defame competitors by misleading consumers with deceptive opinions. This paper proposes a co-training approach called CoSpa (Co-training for Spam review identification to identify spam reviews by two views: one is the lexical terms derived from the textual content of the reviews and the other is the PCFG (Probabilistic Context-Free Grammars rules derived from a deep syntax analysis of the reviews. Using SVM (Support Vector Machine as the base classifier, we develop two strategies, CoSpa-C and CoSpa-U, embedded within the CoSpa approach. The CoSpa-C strategy selects unlabeled reviews classified with the largest confidence to augment the training dataset to retrain the classifier. The CoSpa-U strategy randomly selects unlabeled reviews with a uniform distribution of confidence. Experiments on the spam dataset and the deception dataset demonstrate that both the proposed CoSpa algorithms outperform the traditional SVM with lexical terms and PCFG rules in spam review identification. Moreover, the CoSpa-U strategy outperforms the CoSpa-C strategy when we use the absolute value of decision function of SVM as the confidence.

    Full Text Available Spa and wellness tourism is one of the fastest-growing market segments in the hospitality and tourism industry. The aim of this study is to investigate and identify spa-goers’ characteristics, motivations, preferences and perceptions, providing a better understanding of the main features of this type of tourists’ behavior and expectations from a spa and wellness centre. Primary quantitative research was conducted via a structured questionnaire in a sample of 123 spa customers at Elounda in Crete. The results of the study revealed a number of important factors that influence them when choosing a spa, namely the cleanliness and the maintenance of a spa, the staff knowledge and hygiene, the personnel behavior and courtesy, and the quality of services. In addition, the main reason for visiting the spa is for stress relief/relaxation, followed by physical health improvement and beauty treatments. Findings and discussion of this study are useful to industry practitioners (spa and wellness service providers who wish to develop appropriate marketing strategies and enhance customer satisfaction and academic researchers interested in spa and wellness tourism.

    The present study was conducted to determine the molecular diversity of Staphylococcus aureus strains isolated from human, bovine and food samples based on the polymorphism of the spa gene. A total of 208 S. aureus isolated from human, bovine raw milk and food samples were assessed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and single locus sequence typing (SLST) methods, followed by determination of spa types using Ridom SpaServer. Altogether, 15 distinct RFLP patterns were recorded (I-XV). The highest heterogeneity was observed among S. aureus isolated from humans, whereas most of bovine and food S. aureus isolates indicated certain RFLP patterns. Although most of the isolates from patients showed RFLP pattern I, none of the S. aureus isolated from carriers had this spa pattern. Besides, the results of SLST led to the characterization of 16 spa types, and one of them was a novel spa type which has been registered in Ridom SpaServer for the first time and designated as type t16929. Determination of a high number of shared RFLP patterns between human and food S. aureus isolates indicated possible transmission of S. aureus and the source of food contamination. Thus, effective hygiene measures should be taken to break transmission routes. However, it seems that S. aureus isolated from patients, carriers and bovine should be considered in a different way, since some isolates had similar patterns, while the others showed their own specific pattern.

  15. Phenotypical analysis of the Lactobacillus rhamnosus GG fimbrial spaFED operon: surface expression and functional characterization of recombinant SpaFED pili in Lactococcus lactis.

    A noticeable genomic feature of many piliated Gram-positive bacterial species is the presence of more than one pilus-encoding operon. Paradigmatically, the gut-adapted Lactobacillus rhamnosus GG strain contains two different fimbrial operons in its genome. However, whereas one of these operons (called spaCBA) is encoding for the functionally mucus-/collagen-binding SpaCBA pilus, for the other operon (called spaFED) any native expression of the SpaFED-called pili is still the subject of some uncertainty. Irrespective of such considerations, we decided it would be of relevance or interest to decipher the gross structure of this pilus type, and as well assess its functional capabilities for cellular adhesion and immunostimulation. For this, and by following the approach we had used previously to explicate the immuno-properties of SpaCBA pili, we constructed nisin-inducible expression clones producing either wild-type or SpaF pilin-deleted surface-assembled L. rhamnosus GG SpaFED pili on Lactococcus lactis cells. Using these piliated lactococcal constructs, we found that the pilin-polymerized architecture of a recombinant-produced SpaFED pilus coincides with sequence-based functional predictions of the related pilins, and in fact is prototypical of those other sortase-dependent pilus-like structures thus far characterized for piliated Gram-positive bacteria. Moreover, we confirmed that among the different pilin subunits encompassing spaFED operon-encoded pili, the SpaF pilin is a main adhesion determinant, and when present in the assembled structure can mediate pilus binding to mucus, certain extracellular matrix proteins, and different gut epithelial cell lines. However, somewhat unexpectedly, when recombinant SpaFED pili are surface-attached, we found that they could not potentiate the existing lactococcal cell-induced immune responses so elicited from intestinal- and immune-related cells, but rather instead, they could dampen them. Accordingly, we have now provided

    Full Text Available With 298 heterogeneous soil samples from Yixing (Jiangsu Province, Zhongxiang and Honghu (Hubei Province, this study aimed to combine a successive projections algorithm (SPA with a support vector machine regression (SVMR model (SPA-SVMR model to improve the estimation accuracy of soil organic carbon (SOC contents using the laboratory-based visible and near-infrared (VIS/NIR, 350−2500 nm spectroscopy of soils. The effects of eight spectra pre-processing methods, i.e., Log (1/R, Log (1/R coupled with Savitzky-Golay (SG smoothing (Log (1/R + SG, first derivative with SG smoothing (FD, second derivative with SG smoothing (SD, SG, standard normal variate (SNV, mean center (MC and multiplicative scatter correction (MSC, on SPA-based informative wavelength selection were explored. The SVMR model (i.e., SVMR without SPA and SPA-PLSR model (i.e., SPA combined with partial least squares regression (PLSR were developed and compared with the SPA-SVMR model in order to evaluate the performance of SPA-SVMR. The results indicated that the variables selected by SPA and their distributions were strongly affected by different pre-processing methods, and SG was the optimal pre-processing method for SPA-SVMR model development; the SPA-SVMR model using SG pre-processing and 28 SPA-selected wavelengths obtained a better result (R2V = 0.73, RMSEV = 2.78 g∙kg−1 and RPDV = 1.89 and outperformed the SVMR model (R2V = 0.72, RMSEV = 2.83 g∙kg−1 and RPDV = 1.86 and the SPA-PLSR model (R2V = 0.62, RMSEV = 3.23 g∙kg−1 and RPDV = 1.63. Most of the spectral bands used by the SPA-SVMR model over the near-infrared region were important wavelengths for SOC content estimation. This study demonstrated that the combination of SPA and SVMR is feasible and reliable for estimating SOC content from the VIS/NIR spectra of soils in regions with multiple soil and land-use types.

  20. Large Negative Stress Phase Angle (SPA) attenuates nitric oxide production in bovine aortic endothelial cells.

    2006-06-01

    Hemodynamics plays an important role in cardiovascular physiology and pathology. Pulsatile flow (Q), pressure (P), and diameter (D) waveforms exert wall shear stress (WSS), normal stress, and circumferential strain (CS) on blood vessels. Most in vitro studies to date have focused on either WSS or CS but not their interaction. Recently, we have shown that concomitant WSS and CS affect EC biochemical response modulated by the temporal phase angle between WSS and CS (stress phase angle, SPA). Large negative SPA has been shown to occur in regions of the circulation where atherosclerosis and intimal hyperplasia are prevalent. Here, we report that nitric oxide (NO) biochemical secretion was significantly decreased in response to a large negative SPA of -180 deg with respect to an SPA of 0 degrees in bovine aortic endothelial cells (BAEC) at 5 h. A new hemodynamic simulator for the study of the physiologic SPA was used to provide the hemodynamic conditions of pro-atherogenic (SPA = -180 deg) and normopathic (SPA = 0 deg) states. The role of complex hemodynamics in vascular remodeling, homeostasis, and pathogenesis can be advanced by further assessment of the hypothesis that a large negative SPA is pro-atherogenic.

Gene cloning, PCR, electrophoresis, DNA sequencing, bacteria cells culturing, protein expression and purification, ELISA, Western-blotting were used. Results. The DNA sequences encoding Staphylococcus aureus protein A (SPA and bacterial alkaline phosphatase with enhanced catalytic activity (BAPmut were used for construction of gene encoding fusion protein SPA-BAPmut that was expressed in the high-productive Escherichia coli system and obtained in a soluble form. Cultivation conditions to provide a high-level expression of SPA-ВAPmut (> 1 g/l were determined. The target protein was obtained with purity more than 95 % using ІМАХ method. SPA-ВAPmut is thermostable, and both parts of fusion protein (SPA and BAPmut retain their IgG binding and alkaline phosphatase activity for a long time. SPA-BAPmut was used as a substitute of secondary antibodies in immunoassays. As little as 5 ng of the antigen could be detected in Western blotting and 1 g/ml of IgG in ELISA. Conclusions. The possibility of using SPA-ВAPmut as universal secondary immunoreagent for different types of immunoassays was shown.

    Kronberg, James W.

    1994-01-01

    A proximity sensor based on a closed field circuit. The circuit comprises a ring oscillator using a symmetrical array of plates that creates an oscillating displacement current. The displacement current varies as a function of the proximity of objects to the plate array. Preferably the plates are in the form of a group of three pair of symmetric plates having a common center, arranged in a hexagonal pattern with opposing plates linked as a pair. The sensor produces logic level pulses suitable for interfacing with a computer or process controller. The proximity sensor can be incorporated into a load cell, a differential pressure gauge, or a device for measuring the consistency of a characteristic of a material where a variation in the consistency causes the dielectric constant of the material to change.

The absolute “strangeness” of the crowd (Simmel 1997: 74 expressed, in its purest form, in the absolute proximity of a crowded subway train, does not generally allow for any movements of approach, but only for nervous hostile reactions and submissive hypnotic gestures.

    To assess the radiation exposure of radon spa personnel in Ja'chymov, Czech Republic. The frequency of micronucleus-containing cells and the percentage of centromere-free micronuclei (micronuclei containing only acentric fragments) was determined in peripheral blood lymphocytes of 42 individuals working at the Jachymov spa and 42 control individuals. There was a highly significant increase in the frequency of micronucleus-containing cells as well as the percentage of centromere-free micronuclei in the lymphocytes of spa personnel versus controls. No individual dosimetry data were available. A comparison with results from currently active uranium miners suggests that the individuals examined at the Jachymov spa had accumulated effective doses in the order of several tens of mSv, very similar to those of the miners. The spa personnel in Jachymov needs to be monitored on an individual level.

    The chemical and biological characteristics of Soluble Protective Antigen (SPA) separated from culture fluids of Salmonella enteritidis strain 2547 were analysed. It was shown that SPA has 3-hydroxy, nonpolar fatty acids by thin-layer chromatography. The fatty acids were identified as lauric, myristic, palmitic and 3-hydroxymyristic acid using gas chromatography-mass spectrometry and mass chromatography. These fatty acids are common constituents of the lipid A obtained from S. enteritidis. SPA was found to enhance the plaque-forming cell (PFC)-response to sheep erythrocytes in the recipients' spleen. In addition, SPA enhanced the clotting activity of Limulus amebocyte lysate. These results show that SPA possesses the properties of lipopolysaccharides isolated from strain 2547 by chemical procedures.

    This study aims to investigate whether 2-week spa therapy, as an adjunct to usual pharmacological therapy, has any beneficial effect in patients with rheumatoid arthritis (RA). In this single-blind crossover study, 50 patients were randomly assigned in a 1:1 manner to receive usual pharmacological therapy plus 2-week spa therapy or usual pharmacological therapy alone (period 1.6 months); after a 9-month washout, patients were crossed over to the opposite assignment (period 2.6 months). Spa therapy program included a daily saline balneotherapy session at 36-37 °C for 20 min except Sundays. The clinical outcomes were evaluated at baseline, after spa therapy (2 weeks) and 3 and 6 months after the spa therapy in both period and were pain (Visual Analogue Scale (VAS)), patient and physician global assessments (VAS), Health Assessment Questionnaire (HAQ), and Disease Activity Score (DAS28). Spa therapy was superior to control therapy in improving all the assessed clinical outcomes at the end of the spa therapy. This superiority persisted significantly in physician global assessment (p = 0.010) and with a trend in favor of spa group in patient global assessment (p = 0.058), function (p = 0.092), and disease activity (p = 0.098) at 3 months. Statistically significant improvements were found in spa therapy compared to control in disease activity (p = 0.006) and patient (p = 0.020) and physician global (p = 0.011) assessments, and a trend toward improvements in pain (p = 0.069) and swollen joints (p = 0.070) at 6 months. A 2-week spa therapy adjunct to usual pharmacological therapy provided beneficial clinical effects compared to usual pharmacological therapy alone, in RA patients treated with traditional disease-modifying antirheumatic drugs. These beneficial effects may last for 6 months.

    Very few studies tested the effectiveness of spa therapy in older patients with osteoarthritis. Therefore, we aimed to evaluate the short-term effects of spa therapy in patients aged 65 years and older with generalized, knee, hip, and cervical and lumbar spine osteoarthritis. In an observational retrospective study design at the Medical Ecology and Hydroclimatology Department of Istanbul Medical Faculty, we analyzed the records of 239 patients aged over 65 years with the diagnosis of all types of osteoarthritis who were prescribed a spa therapy course in some spa resorts in Turkey between 7 March 2002 and 31 December 2012. They travelled to a spa resort where they stayed at a thermal spa hotel and followed the usual therapy packages for 2 weeks. Patients were assessed by an experienced physician within a week before the spa journey and within a week after the completion of the spa therapy. Compared with baseline in whole sample, statistically significant improvements were observed in pain (visual analog scale, VAS), patient and physician global assessments (VAS), Health Assessment Questionnaire disability index (HAQ-DI), Lequesne algofunctional index (LAFI) for knee, Western Ontario and McMaster Universities index (WOMAC), Waddell disability index (WDI), and Neck Pain and Disability Scale (NPAD). According to Outcome Measures in Rheumatology—Osteoarthritis Research Society International (OMERACT-OARSI) Set of Responder Criteria, responder rate were 63.8 % (51/80) in generalized, 52 % (13/25) in knee, 50 % (2/4) in hip, 66.7 % (8/12) in lumbar, and 100 % (6/6) in cervical osteoarthritis subgroups. Spa therapy improved pain and physical functional status in older patients with osteoarthritis, especially generalized osteoarthritis and multiple joint osteoarthritis with involvement of knee. This improvement was clinically important in majority of the patients. To confirm the results of this preliminary study, there is a need of a randomized controlled clinical study

    Staphylococcal protein A (spa) is an important virulence factor which enables Staphylococcus aureus to evade host immune responses. Genotypes known as "spa-types", based on highly variable Xr region sequences of the spa-gene, are frequently used to classify strains. A weakness of current spa-typing primers is that rearrangements in the IgG-binding region of the gene cause 1-2% of strains to be designated as "non-typeable". We developed an improved primer which enabled sequencing of all strains, containing any type of genetic rearrangement, in a large study among community carriers and hospital inpatients in Oxfordshire, UK (6110 isolates). We identified eight novel spa-gene variants, plus one previously described. Three of these rearrangements would be designated "non-typeable" using current spa-typing methods; they occurred in 1.8% (72/3905) asymptomatically carried and 0.6% (14/2205) inpatient S. aureus strains. Some individuals were simultaneously colonized by both formerly non-typeable and typeable strains; previously such patients would have been identified as carrying only currently typeable strains, underestimating mixed carriage prevalence and diversity. Formerly non-typeable strains were found in more spa-types associated with multilocus sequence type ST398 (35%), common among livestock, compared to other groups with any non-typeable strains (1-4%), suggesting particular spa-types may have been under-represented in previous human studies. This improved method allows us to spa-type previously non-typeable strains with rearrangements in the spa-gene and to resolve cases of mixed colonization with deletions in one or more strains, thus accounting for hidden diversity of S. aureus in both community and hospital environments.

    Recent studies suggest that SIPA1 encoding a Rap GTPase-activating protein SPA-1 is a candidate metastasis efficiency-modifying gene in human breast cancer. In this study, we investigated the expression and function of SPA-1 in human prostate cancer (CaP). Immunohistochemical studies of tumor specimens from CaP patients revealed a positive correlation of SPA-1 expression with disease progression and metastasis. The correlation was recapitulated in human CaP cell lines; LNCaP that rarely showed metastasis in SCID mice expressed an undetectable level of SPA-1, whereas highly metastatic PC3 showed abundant SPA-1 expression. Moreover, SIPA1 transduction in LNCaP caused prominent abdominal lymph node metastasis without affecting primary tumor size, whereas shRNA-mediated SIPA1 knockdown or expression of a dominant-active Rap1 mutant (Rap1V12) in PC3 suppressed metastasis. LNCaP transduced with SPA-1 (LNCaP/SPA-1) showed attenuated adhesion to the precoated extracellular matrices (ECM) including collagens and fibronectin, due to defective ECM-medicated Rap1 activation. In addition, LNCaP/SPA-1 showed a diminished level of nuclear Brd4, which is known to bind SPA-1, resulting in reduced expression of a series of ECM-related genes. These results suggest that SPA-1 plays an important role in controlling metastasis efficiency of human CaP by regulating the expression of and interaction with ECM in the primary sites. © 2011 Japanese Cancer Association.

    2014-12-01

    spa typing of methicillin-resistant Staphylococcus aureus (MRSA) has traditionally been done by PCR amplification and Sanger sequencing of the spa repeat region. At Hvidovre Hospital, Denmark, whole-genome sequencing (WGS) of all MRSA isolates has been performed routinely since January 2013, and an in-house analysis pipeline determines the spa types. Due to national surveillance, all MRSA isolates are sent to Statens Serum Institut, where the spa type is determined by PCR and Sanger sequencing. The purpose of this study was to evaluate the reliability of the spa types obtained by 150-bp paired-end Illumina WGS. MRSA isolates from new MRSA patients in 2013 (n = 699) in the capital region of Denmark were included. We found a 97% agreement between spa types obtained by the two methods. All isolates achieved a spa type by both methods. Nineteen isolates differed in spa types by the two methods, in most cases due to the lack of 24-bp repeats in the whole-genome-sequenced isolates. These related but incorrect spa types should have no consequence in outbreak investigations, since all epidemiologically linked isolates, regardless of spa type, will be included in the single nucleotide polymorphism (SNP) analysis. This will reveal the close relatedness of the spa types. In conclusion, our data show that WGS is a reliable method to determine the spa type of MRSA.

  10. SPaMOB eat atmospheric methane in Antarctica

    2016-12-01

    The diverse and endemic soil microorganisms that have adapted to the hostile environments in Antarctica are facing challenges due to climate change. The seasonally thawed active layer would exhibit greater daily and/or seasonal temperature variations and different soil moisture regimes, which would cause compositional shifts in these microbial communities. Our preliminary data reveal that Antarctic cryosols from the Taylor Dry Valley are capable of oxidizing methane at atmospheric concentration ( 2 ppmv) at significantly higher rates than the acidic mineral cryosols from the Canadian High Arctic (N 79°) [The ISME J (2015) 9: 1880-1891]. Understanding of this understudied behavior for these active layer cryosols is important for determining the potential methane feedback responses in the Antarctic region. We therefore investigate the biodiversity and genome-wide adaptation of the responsible Southern Polar atmospheric methane-oxidizing bacteria (SPaMOB) in these cryosols. Methane consumption at atmospheric concentration at 4 and 10°C was monitored over a period of four weeks. Two cryosol samples that oxidized methane at both temperatures were selected for molecular analyses. PCR-cloning and sequencing of pmoA (particulate methane monooxygenase beta subunit), the marker gene of methane oxidation, revealed that the SPaMOB in alkaline Antarctic cryosols are closely related to Upland Soil Cluster γ (USCγ), whereas the high Canadian Arctic cryosols contain predominantly USCa-like phylotypes. Four metagenomic libraries were prepared from total DNA and sequenced (2x100bp, Illumina). Quality-filtered reads (avg. 20 M reads per library) were de novo assembled and annotated. A 42.8 kb-long contig containing the pmoCBAcluster was successfully assembled. The pmoA gene is closely related to our USCγ clone sequences. In addition to pmo genes, the presence of genes for conversion of methanol to formaldehyde, production of formate and eventually CO2 indicates SPaMOB's ability

  12. The recombination dynamics of Staphylococcus aureus inferred from spA gene.

    Science.gov (United States)

    Santos-Júnior, Célio D; Veríssimo, António; Costa, Joana

    2016-07-11

    Given the role of spA as a pivotal virulence factor decisive for Staphylococcus aureus ability to escape from innate and adaptive immune responses, one can consider it as an object subject to adaptive evolution and that variations in spA may uncover pathogenicity variations. The population genetic structure was deduced from the extracellular domains of SpA gene sequence (domains A-E and the X-region) and compared to the MLST-analysis of 41 genetically diverse methicillin-resistant (MRSA) and methicillin-susceptible (MSSA) S. aureus strains. Incongruence between tree topologies was noticeable and in the inferred spA tree most MSSA isolates were clustered in a distinct group. Conversely, the distribution of strains according to their spA-type was not always congruent with the tree inferred from the complete spA gene foreseeing that spA is a mosaic gene composed of different segments exhibiting different evolutionary histories. Evidences of a network-like organization were identified through several conflicting phylogenetic signals and indeed several intragenic recombination events (within subdomains of the gene) were detected within and between CC's of MRSA strains. The alignment of SpA sequences enabled the clustering of several isoforms as a result of non-randomly distributed amino acid variations, located in two clusters of polymorphic sites in domains D to B and Xr (a). Nevertheless, evidences of cluster specific structural arrangements were detected reflecting alterations on specific residues with potential impact on S. aureus pathogenicity. The detection of positive selection operating on spA combined with frequent non-synonymous mutations, domain duplication and frequent intragenic recombination events represent important mechanisms acting in the evolutionary adaptive mechanism promoting spA genetic plasticity. These findings argue that crucial allelic forms correlated with pathogenicity can be identified by sequences analysis enabling the design of more

  17. COP1/SPA ubiquitin ligase complexes repress anthocyanin accumulation under low light and high light conditions.

    Science.gov (United States)

    Maier, Alexander; Hoecker, Ute

    2015-01-01

    In Arabidopsis and many other plant species, anthocyanin pigments accumulate only after light exposure and not in darkness. Excess light of very high fluence rates leads to a further, very strong increase in anthocyanin levels. How excess light is sensed is not well understood. Here, we show that mutations in the key repressor of light signaling, the COP1/SPA complex, cause a strong hyperaccumulation of anthocyanins not only under normal light but also under excess, high light conditions. Hence, normal light signaling via COP1/SPA is required to prevent hyperaccumulation of anthocyanins under these high light conditions. However, since cop1 and spa mutants show a similar high-light responsiveness of anthocyanin accumulation as the wild type it remains to be resolved whether COP1/SPA is directly involved in the high-light response itself.

    2013-03-01

    In this article, we validate an experimental paradigm, SPaM, that we first described elsewhere (Luke & Christianson, Memory & Cognition 40:628-641, 2012). SPaM is a synthesis of self-paced reading and masked priming. The primary purpose of SPaM is to permit the study of sentence context effects on early word recognition. In the experiment reported here, we show that SPaM successfully reproduces results from both the self-paced reading and masked-priming literatures. We also outline the advantages and potential uses of this paradigm. For users of E-Prime, the experimental program can be downloaded from our lab website, http://epl.beckman.illinois.edu/.

    Objective To determine whether spa therapy, plus home exercises and usual medical treatment provides any benefit over exercises and usual treatment, in the management of knee osteoarthritis. Methods Large multicentre randomised prospective clinical trial of patients with knee osteoarthritis according to the American College of Rheumatology criteria, attending French spa resorts as outpatients between June 2006 and April 2007. Zelen randomisation was used so patients were ignorant of the other group and spa personnel were not told which patients were participating. The main endpoint criteria were patient self-assessed. All patients continued usual treatments and performed daily standardised home exercises. The spa therapy group also received 18 days of spa therapy (massages, showers, mud and pool sessions). Main Endpoint The number of patients achieving minimal clinically important improvement (MCII) at 6 months, defined as ≥19.9 mm on the visual analogue pain scale and/or ≥9.1 points in a normalised Western Ontario and McMaster Universities osteoarthritis index function score and no knee surgery. Results The intention to treat analysis included 187 controls and 195 spa therapy patients. At 6 months, 99/195 (50.8%) spa group patients had MCII and 68/187 (36.4%) controls (χ2=8.05; df=1; p=0.005). However, no improvement in quality of life (Short Form 36) or patient acceptable symptom state was observed at 6 months. Conclusion For patients with knee osteoarthritis a 3-week course of spa therapy together with home exercises and usual pharmacological treatments offers benefit after 6 months compared with exercises and usual treatment alone, and is well tolerated.

    Staphylococcus aureus is an opportunistic pathogen causing infections in humans and animals. Here we report for the first time the prevalence of nasal carriage, spa typing and antimicrobial resistance of S. aureus in a Tanzanian livestock community. Nasal swabs were taken from 100 humans, 100 pigs and 100 dogs in Morogoro Municipal. Each swab was enriched in Mueller Hinton broth with 6.5% NaCl and subcultured on chromogenic agar for S. aureus detection. Presumptive S. aureus colonies were confirmed to the species level by nuc PCR and analysed by spa typing. Antimicrobial susceptibility patterns were determined by disc diffusion method. S. aureus was isolated from 22% of humans, 4% of pigs and 11% of dogs. A total of 21 spa types were identified: 13, 7 and 1 in human, dogs, and pigs, respectively. Three spa types (t314, t223 and t084) were shared between humans and dogs. A novel spa type (t10779) was identified in an isolate recovered from a colonized human. Antimicrobials tested revealed resistance to ampicillin in all isolates, moderate resistances to other antimicrobials with tetracycline resistance being the most frequent. S. aureus carrier frequencies in dogs and humans were within the expected range and low in pigs. The S. aureus spa types circulating in the community were generally not shared by different hosts and majority of types belonged to known clones. Besides ampicillin resistance, moderate levels of antimicrobial resistance were observed irrespective of the host species from which the strains were isolated.

    The virulence-associated protein-A of Staphylococcus aureus, encoded by spa gene shows a variation in length in different strains. In this study, the spa gene variation in S. aureus strains was studied which were isolated from subclinical cases of bovine mastitis. About 38 isolatesof S. aureus were recovered from Holstein-Friesian (HF) crossbred (n=16) and Rathi cattle (n=22) with subclinical mastitis as per standard procedures, and these isolates were subjected to amplification of spa gene (X-region) by polymerase chain reaction and calculation of number of tandem repeats were done. Of the 16 isolates from H-F crossbred cattle, all with the exception of one isolate produced spa amplicon. Seven isolates produced amplicons of 200 bp, one produced 160 bp, and other seven produced spa amplicon of 150 bp with calculated number of 6, 5, and 4 repeats, respectively, whereas nine different types of amplicons were produced by 22 S. aureus isolates from Rathi cattle, viz., 280, 250, 240, 200, 190, 180, 170, 150, and 140 bp with 10, 8, 8, 6, 6, 6, 5, 4, and 4 repeats, respectively. One of the isolates from Rathi cattle produced two spa amplicons (150 and 190 bp). A greater polymorphism was observed in the S. aureus isolates from Rathi cattle than from H-F crossbreds with subclinical mastitis.

    Aim. To perform a narrative review of spa therapy for management of the fibromyalgia syndrome (FMS), evaluating this traditional time-honored form of therapy in a historical perspective. Methods. Medline was searched using the terms "Spa therapy," "Balneotherapy," and "Fibromyalgia" between 1990 (year of ACR fibromyalgia criteria publication) and April 2013. The Cochrane database was also searched. Publications relating to the implementation of spa therapy and related practices over the centuries were identified through references, searched, and reviewed. Results. Reports of balneotherapy were described from diverse locations throughout Europe and Asia, and various forms of water-related therapy have been incorporated for many musculoskeletal indications. In the management of FMS, spa therapy has generally been shown to be well accepted and moderately effective for symptom reduction. Conclusion. While achieving high-quality evidence-based conclusions is difficult for complex natural therapies such as spa therapy, the existing evidence indicates a positive effect in management of FMS. In view of the long history of this modality in the management of rheumatic pain as well as the inherent difficulties related to pharmacological treatment, the role of spa therapy should currently be recognized as part of a therapeutic program for FMS.

    SPA2 encodes a yeast protein that is one of the first proteins to localize to sites of polarized growth, such as the shmoo tip and the incipient bud. The dynamics and requirements for Spa2p localization in living cells are examined using Spa2p green fluorescent protein fusions. Spa2p localizes to one edge of unbudded cells and subsequently is observable in the bud tip. Finally, during cytokinesis Spa2p is present as a ring at the mother-daughter bud neck. The bud emergence mutants bem1 and bem2 and mutants defective in the septins do not affect Spa2p localization to the bud tip. Strikingly, a small domain of Spa2p comprised of 150 amino acids is necessary and sufficient for localization to sites of polarized growth. This localization domain and the amino terminus of Spa2p are essential for its function in mating. Searching the yeast genome database revealed a previously uncharacterized protein which we name, Sph1p (a2p omolog), with significant homology to the localization domain and amino terminus of Spa2p. This protein also localizes to sites of polarized growth in budding and mating cells. SPH1, which is similar to SPA2, is required for bipolar budding and plays a role in shmoo formation. Overexpression of either Spa2p or Sph1p can block the localization of either protein fused to green fluorescent protein, suggesting that both Spa2p and Sph1p bind to and are localized by the same component. The identification of a 150-amino acid domain necessary and sufficient for localization of Spa2p to sites of polarized growth and the existence of this domain in another yeast protein Sph1p suggest that the early localization of these proteins may be mediated by a receptor that recognizes this small domain.

    Full Text Available The study area lies in the central part of Bela Krajina in south-eastern Slovenia, between the town of Črnomelj and the border crossing at Vinica. It is situated in the vicinity of the Lahinja Landscape Park, where natural and cultural heritage sites interact in the interesting settings of preserved towns and villages. The urban planning concept developed at the workshop was based on the idea that the best space is one where the qualities of "empty spaces" and a fusion with the landscape are recognised. The concept was based on the design of a complex with several connecting structures. A green clearing was defined as the centre of activities, i.e. the core of the activity and pivot of life being the common point of all structures: it is empty, intended to allow for random connections, network organisation or spatial networking, where the key points in the built and natural structures are connected, hence representing the main communication hub between the individual structures. The concept complements the system with accommodation capacities, which are also located outside the spa complex, providing attractive accommodation in a natural setting.

    Spa resorts are known for thousands of years for their healing properties and have been empirically used for the treatment of many inflammatory conditions. Mud is one of the most often used natural materials for preventive, healing and cosmetic reasons and although it has been used since the antiquity, little light has been shed on its physical, chemical and biological properties. In this study we examined the effect of mud extracts on the expression of adhesion molecules (CAMs) by endothelial cells as well as their effects on monocyte adhesion to activated endothelial cells. Most of mud extracts inhibited the expression of VCAM-1 by endothelial cells and reduced monocyte adhesion to activated endothelial cells, indicating a potent anti-inflammatory activity. Furthermore, the mud extracts were tested for their antimicrobial activity; however, most of them appeared inactive against S. aureus and S. epidermidis. One of the mud extracts (showing the best stabilization features) increased significantly the expression of genes involved in cell protection, longevity and hydration of human keratinocytes, such as, collagen 6A1, forkhead box O3, sirtuin-1, superoxide dismutase 1 and aquaporin-3. The present study reveals that mud exerts important beneficial effects including anti-inflammatory and anti-aging activity as well as moisturizing effects, implicating important cosmeceutical applications.

    Full Text Available Over the last decades “wellness spa” industry has experienced a boom around the world. The word “Wellness” has been formed by merging two words: “Well Being” + “fitness”, and appeared in the thirties of the last century in the United States. The primary objective of this movement is an ancient philosophy, according to which there ́s no fulfilled life without the assent of the physical and mental, also physical and spiritual. Hotel guests, today more than ever, want higher quality offer for their money. This means that wellness is today a very important criterion by which customers select hotels. For this reason it is necessary to pay great attention to the planning, design and construction of this part of the hotel facility. The subject of this paper is wellness and spa centers as part of the hotel facility. The task is to investigate and analyze elements of this space, to determine spatial areas of wellness center, as well as their relationships and spatial organization, in order to reach the goal - getting useful guidelines for planning quality wellness center. To all of this could be achieved, we must first go back to distant history where dating back the beginnings of wellness.

    Very few studies tested the effectiveness of spa therapy in older patients with osteoarthritis. Therefore, we aimed to evaluate the short-term effects of spa therapy in patients aged 65 years and older with generalized, knee, hip, and cervical and lumbar spine osteoarthritis. In an observational retrospective study design at the Medical Ecology and Hydroclimatology Department of Istanbul Medical Faculty, we analyzed the records of 239 patients aged over 65 years with the diagnosis of all types of osteoarthritis who were prescribed a spa therapy course in some spa resorts in Turkey between 7 March 2002 and 31 December 2012. They travelled to a spa resort where they stayed at a thermal spa hotel and followed the usual therapy packages for 2 weeks. Patients were assessed by an experienced physician within a week before the spa journey and within a week after the completion of the spa therapy. Compared with baseline in whole sample, statistically significant improvements were observed in pain (visual analog scale, VAS), patient and physician global assessments (VAS), Health Assessment Questionnaire disability index (HAQ-DI), Lequesne algofunctional index (LAFI) for knee, Western Ontario and McMaster Universities index (WOMAC), Waddell disability index (WDI), and Neck Pain and Disability Scale (NPAD). According to Outcome Measures in Rheumatology-Osteoarthritis Research Society International (OMERACT-OARSI) Set of Responder Criteria, responder rate were 63.8 % (51/80) in generalized, 52 % (13/25) in knee, 50 % (2/4) in hip, 66.7 % (8/12) in lumbar, and 100 % (6/6) in cervical osteoarthritis subgroups. Spa therapy improved pain and physical functional status in older patients with osteoarthritis, especially generalized osteoarthritis and multiple joint osteoarthritis with involvement of knee. This improvement was clinically important in majority of the patients. To confirm the results of this preliminary study, there is a need of a randomized controlled clinical

    To evaluate the virulence determinants and genetic diversity of Staphylococcus aureus from bovine subclinical mastitis milk. PCR detection of virulence genes was performed for 173 Staph. aureus from bovine subclinical mastitis milk. Further, genetic diversity was analysed by agr and spa typing followed by pulsed field gel electrophoresis (PFGE) of selected isolates. Screening of virulence genes (n = 19) showed the adherence genes viz. fnbA, clfA, fnbB and cna in 98·8, 97·1, 68·8 and 28·3 percentage of isolates, respectively, and 80 strains (46·24%) positive for enterotoxin genes were distributed as 23 toxinotypes, of which, 5 genotypes contained a single gene and the rest comprised of multiple toxin genes. Out of agr type-1 (87·3%), 74·2 per cent belonged to the three predominant spa types. Of 27 spa types, 11 were identified for the first time. The predominant spa types were t267 (N =44), t359 (N = 42) and t6877 (N =29), which together accounts to 66·5 per cent of isolates. PFGE analysis of isolates (N = 45) covering all the spa types revealed mostly similar or closely related pulsotypes. Local emergence of spa type t6877 in herd-dependant manner was observed. spa sequence-based phylogenetic analysis suggested t267 as the ancestral clone of t359, t6877 and other spa types except two. Heterogenous virulence profile of the isolates had no significant association with the genotype. High prevalence of agr group I reaffirms their association with persistent subclinical mastitis. The spa type t267 appears to be the ancestral clone endemic in the region causing subclinical mastitis. In addition, few new spa types have emerged in the geographic region. Gives an insight into the genetic and evolutionary behaviour of Staph. aureus associated with bovine subclinical mastitis in India. The study would pave the way for devising effective control strategy for bovine mastitis in Indian context. © 2013 The Society for Applied Microbiology.

    This study aims to investigate whether 2-week spa therapy, as an adjunct to usual pharmacological therapy, has any beneficial effect in patients with rheumatoid arthritis (RA). In this single-blind crossover study, 50 patients were randomly assigned in a 1:1 manner to receive usual pharmacological therapy plus 2-week spa therapy or usual pharmacological therapy alone (period 1.6 months); after a 9-month washout, patients were crossed over to the opposite assignment (period 2.6 months). Spa therapy program included a daily saline balneotherapy session at 36-37 °C for 20 min except Sundays. The clinical outcomes were evaluated at baseline, after spa therapy (2 weeks) and 3 and 6 months after the spa therapy in both period and were pain (Visual Analogue Scale (VAS)), patient and physician global assessments (VAS), Health Assessment Questionnaire (HAQ), and Disease Activity Score (DAS28). Spa therapy was superior to control therapy in improving all the assessed clinical outcomes at the end of the spa therapy. This superiority persisted significantly in physician global assessment (p = 0.010) and with a trend in favor of spa group in patient global assessment (p = 0.058), function (p = 0.092), and disease activity (p = 0.098) at 3 months. Statistically significant improvements were found in spa therapy compared to control in disease activity (p = 0.006) and patient (p = 0.020) and physician global (p = 0.011) assessments, and a trend toward improvements in pain (p = 0.069) and swollen joints (p = 0.070) at 6 months. A 2-week spa therapy adjunct to usual pharmacological therapy provided beneficial clinical effects compared to usual pharmacological therapy alone, in RA patients treated with traditional disease-modifying antirheumatic drugs. These beneficial effects may last for 6 months.

    We study the fuzzy soft proximity spaces in Katsaras's sense. First, we show how a fuzzy soft topology is derived from a fuzzy soft proximity. Also, we define the notion of fuzzy soft δ-neighborhood in the fuzzy soft proximity space which offers an alternative approach to the study of fuzzy soft proximity spaces. Later, we obtain the initial fuzzy soft proximity determined by a family of fuzzy soft proximities. Finally, we investigate relationship between fuzzy soft proximities and proximities. PMID:25793224

    Early diagnosis, monitoring of disease activity, prediction of treatment response, and structural outcome remain major challenges in spondyloarthritis (SpA). Biomarkers could play a role in addressing these challenges, but in SpA there is a lack of suitable biomarkers. Areas covered: As SpA is clinically and pathophysiologically closely related to psoriasis and inflammatory bowel disease (IBD), we reviewed in literature, the value of serum biomarkers in these conditions with the aim to find potential candidates for assessing SpA. Expert commentary: Candidates of interest were antimicrobial peptides, including serum human beta defensin-2 (hBD-2) and lipocalin-2 (LCN-2), and class-1 MHC molecule beta2-microglobulin. Since these biomarkers are relevant in psoriasis and/or IBD from a pathophysiological point of view, and may play a role in the pathogenesis of SpA, we recommend further exploration of their value as biomarker in the diagnosis and prognosis of SpA.

    Assess the best approach to type methicillin-resistant Staphylococcus aureus (MRSA), Staphylococcal protein A (spa) typing, multiple-locus variable number tandem repeat analysis (MLVA) or both. Discriminatory power of spa typing and MLVA was determined using 20,771 MRSA isolates. There were twice as many MLVA types (MTs) as spa types present in the collection. Among the top 70% of the isolates, 37 spa types and 139 MTs were found. MLVA diversity among the top-10 spa types was high (diversity index 0.96), while spa diversity among the top-10 MTs was much lower (diversity index 0.83). The probability that two MRSA isolates with the same spa type also had the same MT was low (Wallace's coefficient 0.27). By contrast, most MRSA isolates yielding the same MT also had the same spa type (Wallace's coefficient 0.90). MLVA is superior to spa typing and will suffice to characterize MRSA isolates for surveillance.

    We investigated the immune camouflage effects of methoxy polyethylene glycol succinimidyl propionate (mPEG-SPA) on corneal antigens and explored a novel approach for reducing corneal antigenicity, thereby decreasing corneal graft rejection. Importantly, this approach did not alter normal local immunity. Corneal grafts were treated with mPEG-SPA 5KD or 20KD (3% W/V), which could shield major histocompatibility antigen class I molecules (RT1-A) of corneal grafts. Skin grafts of Wistar rats were transplanted to SD rats. Then the splenic lymphocytes were isolated from SD rats. Subsequently, the lymphocytes were co-cultured with autologous corneal grafts or untreated corneal grafts and PEGylated grafts treated with mPEG-SPA 5KD or 20KD obtained from the counterpart skin donors, which were used as autologous control, allogeneic control, mPEG-SPA 5KD group and mPEG-SPA 20KD group, respectively. Lymphocyte proliferation was lower in mPEG-SPA 5KD group and mPEG-SPA 20KD group than in the allogeneic control. SD rats with corneal neovascularisation were used as recipients for high-risk corneal transplantation and were randomly divided into four groups: autologous control, allogeneic control, mPEG-SPA 5KD group and mPEG-SPA 20KD group. The recipients received corneal grafts from Wistar rats. Corneal graft survival was prolonged and graft rejection was reduced in the mPEG-SPA 5KD group and the mPEG-SPA 20KD group compared to the allogeneic control. Thus, we think that mPEG-SPA could immunologically camouflage corneal antigens to prolong corneal grafts survival in high-risk transplantation. Copyright © 2014 Elsevier Ltd. All rights reserved.

  2. An insight into the immune roles of surfactant proteins, SP-A and SP-D

    2012-06-01

    Full Text Available Pulmonary surfactant proteins, SP-A and SP-D, are hydrophilic collagen-containing calcium-dependent lectins, which appear to have a range of innate immune functions at pulmonary as well as extrapulmonary sites. These proteins bind to target ligands on pathogens, allergens and apoptotic cells via C-terminal carbohydrate recognition domains while the collagen region brings about the effector functions. SP-A and SP-D deals with various pathogens triggering a range of innate immune mechanisms such as agglutination/aggregation, enhancement of phagocytosis and killing reactions, and growth inhibition. SP-A and SP-D have also been involved in the control of pulmonary inflammation including allergy and asthma, and hence, they are likely to central issues in a range of pathological situations. There is also emerging evidence to suggest that SP-A and SP-D are capable of linking innate immunity with adaptive immunity that includes modulation of dendritic cell function and helper T cell polarisation. It is clear now that SP-A and SP-D are potent innate immune molecules in the lungs. This review is a summary of their immunological properties in general and their importance in human health and disease.

    Although body-warming with hot spa-bathing has been proposed to exert medical therapeutic effects on certain diseases, whether body-warming has preventive and promotive effects remains unknown. To clarify this issue, an epidemiological questionnaire study regarding personal hot spa-bathing habits and disease history was carried out in Japan, where individuals engage in daily warm water bathing. Questionnaires regarding hot spa-bathing habits and disease history were randomly sent to 20,000 residents aged ≥65 years living in Beppu, a city in Japan that has the highest concentration of hot spa sources in the world. The results showed that habitual hot spa-bathing exerts preventive or promotive effects on the occurrence of certain diseases, such as hypertension (preventive) and collagen disease (promotive) in women, and cardiovascular diseases (preventive) and colon cancer survival (promotive) in men. These findings suggest that habitual body warming is an effective and economical method with beneficial preventive and promotive effects on various diseases.

  6. The blue light-induced interaction of cryptochrome 1 with COP1 requires SPA proteins during Arabidopsis light signaling.

    2017-10-01

    Plants constantly adjust their growth, development and metabolism to the ambient light environment. Blue light is sensed by the Arabidopsis photoreceptors CRY1 and CRY2 which subsequently initiate light signal transduction by repressing the COP1/SPA E3 ubiquitin ligase. While the interaction between cryptochromes and SPA is blue light-dependent, it was proposed that CRY1 interacts with COP1 constitutively, i.e. also in darkness. Here, our in vivo co-immunoprecipitation experiments suggest that CRY1 and CRY2 form a complex with COP1 only after seedlings were exposed to blue light. No association between COP1 and CRY1 or CRY2 was observed in dark-grown seedlings. Thus, our results suggest that cryptochromes bind the COP1/SPA complex after photoactivation by blue light. In a spa quadruple mutant that is devoid of all four SPA proteins, CRY1 and COP1 did not interact in vivo, neither in dark-grown nor in blue light-grown seedlings. Hence, SPA proteins are required for the high-affinity interaction between CRY1 and COP1 in blue light. Yeast three-hybrid experiments also show that SPA1 enhances the CRY1-COP1 interaction. The coiled-coil domain of SPA1 which is responsible for COP1-binding was necessary to mediate a CRY1-SPA1 interaction in vivo, implying that-in turn-COP1 may be necessary for a CRY1-SPA1 complex formation. Hence, SPA1 and COP1 may act cooperatively in recognizing and binding photoactivated CRY1. In contrast, the blue light-induced association between CRY2 and COP1 was not dependent on SPA proteins in vivo. Similarly, ΔCC-SPA1 interacted with CRY2, though with a much lower affinity than wild-type SPA1. In total, our results demonstrate that CRY1 and CRY2 strongly differ in their blue light-induced interaction with the COP1/SPA complex.

    Osteoarthritis (OA) continues to be one of the leading causes of 'years lived with disability' worldwide. Symptomatic knee OA is highly prevalent among people aged 50 years and over and is destined to become an ever more important healthcare problem. Current management of knee OA includes non-pharmacological and pharmacological treatments. Spa therapy is one of the most commonly used non-pharmacological approaches for OA in many European countries, as well as in Japan and Israel. Despite its long history and popularity, spa treatment is still the subject of debate and its role in modern medicine continues to be unclear. The objective of this review is to summarize the currently available information on clinical effects and mechanisms of action of spa therapy in knee OA. Various randomized controlled clinical trials (RCTs) were conducted to assess the efficacy and tolerability of balneotherapy and mud-pack therapy in patients with knee OA. Data from these clinical trials support a beneficial effect of spa therapy on pain, function and quality of life in knee OA that lasts over time, until 6-9 months after the treatment. The mechanisms by which immersion in mineral or thermal water or the application of mud alleviate suffering in OA are not fully understood. The net benefit is probably the result of a combination of factors, among which the mechanical, thermal and chemical effects are most prominent. In conclusion, spa therapy seems to have a role in the treatment of knee OA. Additional RCTs and further studies of mechanisms of action with high methodological quality are necessary to prove the effects of spa therapy.

    The SpaRibs topology of an aircraft wing has a significant effect on its structural behavior and stability as well as the flutter performance. The development of additive manufacturing techniques like Electron Beam Free Form Fabrication (EBF3) has made it feasible to manufacture aircraft wings with curvilinear spars, ribs (SpaRibs) and stiffeners. In this article a new global-local optimization framework for wing with multiple sections using curvilinear SpaRibs is described. A single design space is used to parameterize the SpaRibs geometry. This method has been implemented using MSC-PATRAN to create a broad range of SpaRibs topologies using limited number of parameters. It ensures C0 and C1 continuities in SpaRibs geometry at the junction of two wing sections with airfoil thickness gradient discontinuity as well as mesh continuity between all structural components. This method is advantageous in complex multi-disciplinary optimization due to its potential to reduce the number of design variables. For the global-local optimization the local panels are generated by an algorithm which is totally based on a set algebra on the connectivity matrix data. The great advantage of this method is that it is completely independent of the coordinates of the nodes of the finite element model. It is also independent of the order in which the elements are distributed in the FEM. The code is verified by optimizing of the CRM Baseline model at trim condition at Mach number equal to 0.85 for five different angle of attack (-2deg, 0deg,2deg,4deg and 6deg). The final weight of the wing is 19,090.61 lb. This value is comparable to that obtained by Qiang et al. 6 (19,269 lb).

    Data from recent lunar orbital missions have provided critical insight into the surface composition, morphology, and geologic history of the Moon. A key region that has benefited from this new data is the South Pole-Aitken Basin (SPA), a key area for future sample return]. A key area of investigation of SPA has been the characterization of its surface, detailing the interior composition, geologic evolution, and possible exposure of deep-seated materials. Recently we have applied a number of datasets to ascertain the origin of surfaces in central SPA and identify units that represent the ancient SPA-derived impact melt and those that represent volcanic activity. Here we apply a technique that utilizes high-resolution topographic data to remove local slopes to highlight subtle topographic variations. Such detrended data allows us to characterize units that are either ancient (SPA impact melt) or that represent subsequent volcanic activity.

    spa-typing of methicillin-resistant Staphylococcus aureus (MRSA) has been used widely in clinical diagnostics and epidemiological studies. The aim of this study was to evaluate high-resolution melting (HRM) as a rapid and cost-effective method, to replace DNA-sequencing, for spa-typing in a global collection of 50 MRSA isolates. The polymorphic X region of the spa gene was amplified by colony PCR using the SensiMix HRM kit, and the melting temperature (Tm) and melting curves of the amplicons were analyzed in close tubes using a Rotor-Gene 6000 instrument. Fifteen out of 19 spa-types each had a distinct Tm, which was sufficient to unambiguously type each of these spa-types. The remaining four spa-types could not be separated by Tm alone: t008 and t2770 shared a Tm (80.3°C) and t021 and t311 shared a Tm (80.0°C). However, they could be separated based on the shapes of their melting curves. There are discrepancies between the findings of the present study and those of previous studies, suggesting that standardization remains a challenge for cross-referencing. HRM-based spa-typing is reproducible, simple, rapid, and cost-effective. t037 is prevalent in Brazil and Sudan, while diverse spa-types are found in Scotland and Saudi Arabia. Standardization is required for cross-referencing between laboratories globally. Copyright © 2015. Published by Elsevier Ltd.

    Osteoarthritis (OA) is the most common form of arthritis and its current treatment includes non-pharmacological and pharmacological modalities. Spa therapy represents a popular treatment for many rheumatic diseases. The aim of this review was to summarize the currently available information on clinical effects and mechanisms of action of spa therapy in OA of the hand. We conducted a search of the literature to extract articles describing randomized clinical trials (RCTs) in hand OA published in the period 1952-2015. We identified three assessable articles reporting RCTs on spa therapy in hand OA. Data from these clinical trials support a beneficial effect of spa therapy on pain, function and quality of life in hand OA. Spa therapy seems to have a role in the treatment of hand OA. However, additional RCTs are necessary to clarify the mechanisms of action and the effects of the application of thermal treatments.

    Type III Secretion Systems (T3SSs) are structurally conserved nanomachines that span the inner and outer bacterial membranes, and via a protruding needle complex contact host cell membranes and deliver type III effector proteins. T3SS are phylogenetically divided into several families based on structural basal body components. Here we have studied the evolutionary and functional conservation of four T3SS proteins from the Inv/Mxi-Spa family: a cytosolic chaperone, two hydrophobic translocators that form a plasma membrane-integral pore, and the hydrophilic 'tip complex' translocator that connects the T3SS needle to the translocon pore. Salmonella enterica serovar Typhimurium (S. Typhimurium), a common cause of food-borne gastroenteritis, possesses two T3SSs, one belonging to the Inv/Mxi-Spa family. We used invasion-deficient S. Typhimurium mutants as surrogates for expression of translocator orthologs identified from an extensive phylogenetic analysis, and type III effector translocation and host cell invasion as a readout for complementation efficiency, and identified several Inv/Mxi-Spa orthologs that can functionally substitute for the S. Typhimurium chaperone and translocator proteins. Functional complementation correlates with amino acid sequence identity between orthologs, but varies considerably between the four proteins. This is the first in-depth survey of the functional interchangeability of Inv/Mxi-Spa T3SS proteins acting directly at the host-pathogen interface. © 2016 John Wiley & Sons Ltd.

    The current study presents the results of the activity of radionuclides in spa waters, and evaluates their radiological influences on the population consuming these waters in the Central and Eastern Black Sea regions of Turkey. Since these waters are used for therapy and consumption purposes unconsciously, their radiological impact on the people was computed by taking into consideration the annual intake through ingestion of 226 Ra, 232 Th, 40 K, 137 Cs and 222 Rn. The mean activities were estimated to be 11.35 for gross alpha, 6.23 for gross beta, 2.96 for 226 Ra, 0.42 for 232 Th, 0.069 for 137 Cs, 0.19 for 40 K, and 267 Bq L -1 for 222 Rn, respectively. The estimated effective doses from spa water were found to be 49.77 µSv a -1 ( 226 Ra), 5.95 µSv a -1 ( 232 Th), 0.07 µSv a -1 ( 137 Cs), 0.83 µSv a -1 ( 40 K) and 56.03 µSv a -1 ( 222 Rn). These values were evaluated and compared with related verified values from literature. Also, physico-chemical characterizations of spa water samples considered in the current study were investigated. This study would be useful for consumers and official authorities for the assessment of radiation exposure risk due to usage of the considered spa waters.

    The aim of this article is to present the course of privatization of spa companies in Poland during the period 2001-2011. We discuss assumptions of the privatization process, as well as actual implementation, having identified the process as chaotic and inconsistent with prior legal provisions. We found that in its applied form the process resulted in limitation of the therapeutic potential of spas, and reduction of the State's ability to implement health policy in a legally determined form. We also found that privatization potentially improved spa infrastructure standards and increases the tourist potential of spa resorts. We recommend that clear eligibility criteria are applied to institutions in the privatization process, as well as the provision of legal guarantees for access to spa services financed from public resources. Such guarantees should be made a public obligation, to ensure the availability of services for insured persons, and there should be an obligation to maintain a specific part of a given institution's potential for the needs of patients funded by public health insurance.

    The presence of pathogenic microorganisms in public spa pools poses a serious threat to human health. The problem is particularly acute in herbal spas, in which the herbs and microorganisms may interact and produce undesirable consequences. Accordingly, the present study investigated the effectiveness of a combined disinfectant containing chlorine dioxide and sodium hypochlorite in improving the water quality of a public herbal spa in Taiwan. Water samples were collected from the spa pool and laboratory tests were then performed to measure the variation over time of the microorganism content (total CFU and total coliforms) and residual disinfectant content given a single disinfection mode (SDM) with disinfectant concentrations of 5.2 × 10, 6.29 × 10, 7.4 × 10, and 11.4 × 10(-5) N, respectively. Utilizing the experience gained from the laboratory tests, a further series of on-site investigations was performed using three different disinfection modes, namely SDM, 3DM (once every 3 h disinfection mode), and 2DM (once every 2 h disinfection mode). The laboratory results showed that for all four disinfectant concentrations, the CFU concentration reduced for the first 6 h following SDM treatment, but then increased. Moreover, the ANOVA results showed that the sample treated with the highest disinfectant concentration (11.4 × 10(-5) N) exhibited the lowest rate of increase in the CFU concentration. In addition, the on-site test results showed that 3DM and 2DM treatments with disinfectant concentrations in excess of 9.3 × 10 and 5.5 × 10(-5) N, respectively, provided an effective reduction in the total CFU concentration. In conclusion, the experimental results presented in this study provide a useful source of reference for spa businesses seeking to improve the water quality of their spa pools.

  14. Epithelial adhesion mediated by pilin SpaC is required for Lactobacillus rhamnosus GG-induced cellular responses.

    Lactobacillus rhamnosus GG is a widely used probiotic, and the strain's salutary effects on the intestine have been extensively documented. We previously reported that strain GG can modulate inflammatory signaling, as well as epithelial migration and proliferation, by activating NADPH oxidase 1-catalyzed generation of reactive oxygen species (ROS). However, how strain GG induces these responses is unknown. Here, we report that strain GG's probiotic benefits are dependent on the bacterial-epithelial interaction mediated by the SpaC pilin subunit. By comparing strain GG to an isogenic mutant that lacks SpaC (strain GGΩspaC), we establish that SpaC is necessary for strain GG to adhere to gut mucosa, that SpaC contributes to strain GG-induced epithelial generation of ROS, and that SpaC plays a role in strain GG's capacity to stimulate extracellular signal-regulated kinase/mitogen-activated protein kinase (ERK/MAPK) signaling in enterocytes. In addition, we show that SpaC is required for strain GG-mediated stimulation of cell proliferation and protection against radiologically inflicted intestinal injury. The identification of a critical surface protein required for strain GG to mediate its probiotic influence advances our understanding of the molecular basis for the symbiotic relationship between some commensal bacteria of the gut lumen and enterocytes. Further insights into this relationship are critical for the development of novel approaches to treat intestinal diseases. Copyright © 2014, American Society for Microbiology. All Rights Reserved.

    Protein A from Staphylococcus aureus (SpA) is a 40-60 kDa cell-wall component, composed of five homologous immunoglobulin (Ig)-binding domains folded into a three-helix bundle. Each of these five domains is able to bind Igs from many different mammalian species. Recombinant SpA is widely used as a component of diagnostic kits for the detection and purification of IgGs from serum or other biological fluids. In this study, purified SpA was adsorbed and covalently linked to Bacillus subtilis spores. Spores are extremely stable cell forms and are considered as an attractive platform to display heterologous proteins. A sample containing about 36 μg of SpA was covalently immobilized on the surface of 4 × 10(10) spores. Spore-bound SpA retained its IgG-binding activity, even after seven consecutive binding and washing steps, suggesting that it can be recycled and utilized several times. FACS analysis revealed that spores with covalently attached SpA had significantly improved fluorescence intensities when compared to those of spores with adsorbed SpA, suggesting that the covalent approach is more efficient than sole adsorption regarding protein attachment to the spore surface.

    2005-12-01

    Full Text Available Abstract Background α1-antitrypsin and surfactant protein-A (SP-A are major lung defense proteins. With the hypothesis that SP-A could bind α1-antitrypsin, we designed a series of in vitro experiments aimed at investigating the nature and consequences of such an interaction. Methods and results At an α1-antitrypsin:SP-A molar ratio of 1:1, the interaction resulted in a calcium-dependent decrease of 84.6% in the association rate constant of α1-antitrypsin for neutrophil elastase. The findings were similar when SP-A was coupled with the Z variant of α1-antitrypsin. The carbohydrate recognition domain of SP-A appeared to be a major determinant of the interaction, by recognizing α1-antitrypsin carbohydrate chains. However, binding of SP-A carbohydrate chains to the α1-antitrypsin amino acid backbone and interaction between carbohydrates of both proteins are also possible. Gel filtration chromatography and turnover per inactivation experiments indicated that one part of SP-A binds several molar parts of α1-antitrypsin. Conclusion We conclude that the binding of SP-A to α1-antitrypsin results in a decrease of the inhibition of neutrophil elastase. This interaction could have potential implications in the physiologic regulation of α1-antitrypsin activity, in the pathogenesis of pulmonary emphysema, and in the defense against infectious agents.

    Full Text Available The limited predictive value of semen analysis in achieving natural conception or in IVF outcome confirms the need for sperm function tests to determine optimal management. We reviewed HZA and SPA predictive power in IVF outcome, with statistical significance of diagnostic power of the assays. HZA was readily efficient in predicting IVF outcome, while evident inconsistency among the studies analysed framed the SPA’s role in male fertility evaluation. Considerable variation was noted in the diagnostic accuracy values of SPA with wide sensitivity (52–100%, specificity (0–100%, and PPV (18–100% and NPV (0–100% together with fluctuation and notable differentiation in methodology and cutoff values employed by each group. HZA methodology was overall consistent with minor variation in cutoff values and oocyte source, while data analysis reported strong correlation between HZA results with IVF outcome, high sensitivity (75–100%, good specificity (57–100%, and high PPV (79–100% and NPV (68–100%. HZA correlated well with IVF outcome and demonstrated better sensitivity/specificity and positive/negative predictive power. Males with normal or slightly abnormal semen profiles could benefit by this intervention and could be evaluated prior to referral to assisted reproduction. HZA should be used in a sequential fashion with semen analysis and potentially other bioassays in an IVF setting.

  1. Novel expression of a functional trimeric fragment of human SP-A with efficacy in neutralisation of RSV

    DEFF Research Database (Denmark)

    Watson, Alastair; Kronqvist, Nina; Spalluto, C Mirella

    2017-01-01

    Respiratory syncytial virus (RSV) is the leading cause of bronchiolitis and hospitalisation of infants in developed countries. Surfactant protein A (SP-A) is an important innate immune molecule, localized in pulmonary surfactant. SP-A binds to carbohydrates on the surface of pathogens in a calcium......-dependent manner to enable neutralisation, agglutination and clearance of pathogens including RSV. SP-A forms trimeric units and further oligomerises through interactions between its N-terminal domains. Whilst a recombinant trimeric fragment of the closely related molecule (surfactant protein D) has been shown...... to retain many of the native protein's functions, the importance of the SP-A oligomeric structure in its interaction with RSV has not been determined. The aim of this study was to produce a functional trimeric recombinant fragment of human (rfh)SP-A, which lacks the N-terminal domain (and the capacity...

  2. The activities of the E3 ubiquitin ligase COP1/SPA, a key repressor in light signaling.

    2017-06-01

    Light is a critical signal to integrate plant growth and development with the environment. Downstream of photoreceptors, the E3 ubiquitin ligase COP1/SPA is a key repressor of photomorphogenesis which targets many positive regulators of light signaling, mainly transcription factors, for degradation in darkness. In light-grown plants COP1/SPA activity is repressed, allowing light responses to occur. This review provides an overview on our current knowledge on COP1/SPA repressor function, focusing in particular on the roles of the respective protein domains and the mechanisms of light-induced inactivation of COP1/SPA. Moreover, we summarize how COP1 activity is regulated by other interacting proteins, such as a SUMO E3 ligase and Phytochrome-Interacting Factors (PIFs), as well as by hormones. At last, several novel functions of COP1 that were recently revealed are included. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available The famous tradition of spa places like cultural centers and health resorts with unique potential in natural curing springs could be a solid, but not an adequate, ground for their development according to the challenges of contemporary society. The renewed interest in the territorial aspects of tourism as a response to globalization enhanced the influence of spatial factor (tourismscape on current on tourism demand. The network of flows, relationships and interactions, as the core of the territoriality concept, is not something new and unknown in regional planning but requires a new analytical tool for researching the global network connectivity. This paper analyzes the concept of territorial networking in the system of physical, functional and organizational networks as one of the crucial aspects in the development of well balanced tourism region. The consideration aim is to examine and define the relevant indicators that may specify the level of competitiveness of spa region in the global tourism market.

    There has been a marked increase in the incidence of MRSA during the past decade in Norway, a country with one of the lowest prevalence's and an active "search-and-destroy" policy applied to hospital settings. To characterize the trends of notification rates of community associated (CA) and healthcare associated (HA) MRSA in Norway and explore the diversity and circulation of MRSA spa-types within and outside healthcare settings. We conducted a registry-based study on notified MRSA infections and colonizations in Norway between 2006 and 2015. The diversity and abundance of CA- and HA-MRSA spa-types were compared using novel ecological diversity measures, Hill numbers. During the study period, the monthly notification rate increased 6.9-fold and 1.8-fold among CA- and HA-MRSA, respectively; the increase was steeper among colonizations than infections. In both settings the distribution of spa-types was uneven, with a few dominant spa-types and many singletons. The spa-type diversity of CA-MRSA was higher than HA-MRSA in terms of different types (685 vs. 481) and increased during the study period. However, the diversity associated with the dominant spa-types were similar and remained stable. A high overlap of spa-types was estimated between the settings; spa-t002, t019 and t008 were the most common. The present findings suggest a strong connection between CA- and HA-MRSA epidemiology in Norway. If the fast-growing trend of CA-MRSA continues, in the years to come, it may challenge current guidelines and infection control of MRSA in healthcare environments. Copyright © 2017.

    2009-01-01

    Full Text Available Purpose: To characterize methicillin-resistant Staphylococcus aureus (MRSA strains by molecular typing based on polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP of spa gene and to assess the utility of spa genotyping over bacteriophage typing in the discrimination of the strains. Materials and Methods: Studies were undertaken on 125 MRSA strains representing the most predominant phage types and the non phage typeable strains. Strains were typed by bacteriophage typing and PCR-RFLP of spa gene. DNA sequence analysis of the amplified spa gene fragment of the representative RFLP patterns was performed using standard protocols. Results: All the strains resistant to oxacillin were found to contain mec A gene. Fifty-two per cent of these strains were typeable by the international basic set of 23 phages. Five different PCR-RFLP patterns were observed among 125 MRSA strains. Non phage typeable strains were differentiated into four PCR-RFLP patterns. Sequencing of the spa gene from the representative strains of each RFLP pattern confirmed the length of these restriction fragments due to variation in the 24 bp and the 174 bp tandem repeats. It also revealed the presence of three new spa repeat patterns. Conclusion: The study demonstrates the importance of spa genotyping in the discrimination of MRSA strains, which were otherwise indistinguishable by bacteriophage typing. spa genotyping allowed differentiation of strains within a particular phage type. Nucleotide sequencing of isolates of different PCR-RFLP patterns indicated a correlation between the RFLP patterns of a variable number of tandem repeats and the phage type. The study provides valuable information on the epidemiological characterization of MRSA strains.

    Adipocytokine, including leptin and adiponectin, may play an important role in the pathophysiology of osteoarthritis (OA). Spa therapy is one of the most commonly used non-pharmacological approaches for OA, but its mechanisms of action are not completely known. The aim of the present study was to assess whether spa therapy modified plasma levels of leptin and adiponectin in thirty patients with knee OA treated with a cycle of a combination of daily locally applied mud-packs and bicarbonate-sulphate mineral bath water. Leptin and adiponectin plasma levels were assessed at baseline and after 2 weeks, upon completion of the spa treatment period. The concentrations of leptin and adiponectin were measured by ELISA. At basal time, plasma leptin levels were significantly correlated with body mass index (BMI) and gender, but no significant correlation was found with patient age, duration of disease, radiographic severity of knee OA, VAS score or Lequesne index. There was no correlation between plasma adiponectin level and BMI, gender and age, duration of the disease, radiographic severity of knee OA and VAS score. A significant correlation of plasma adiponectin levels was found only with the Lequesne index. At the end of the mud-bath therapy cycle, serum leptin levels showed a slight but not significant increase, while a significant decrease (P leptin and adiponectin concentrations after treatment were not correlated with other clinical parameters. In conclusion, our data show that spa therapy can modify plasma levels of the adipocytokines leptin and adiponectin, important mediators of cartilage metabolism. Whether this effect may play a potential role in OA needs further investigations.

    Staphylococcus aureus is both human commensal and an important human pathogen, responsible for community-acquired and nosocomial infections ranging from superficial wound infections to invasive infections, such as osteomyelitis, bacteremia and endocarditis, pneumonia or toxin shock syndrome with a mortality rate up to 40%. S. aureus reveals a high genetic polymorphism and detecting the genotypes is extremely useful to manage and prevent possible outbreaks and to understand the route of infection. One of current and expanded typing method is based on the X region of the spa gene composed of a succession of repeats of 21 to 27 bp. More than 10000 types are known. Extracting the repeats is impossible by hand and needs a dedicated software. Unfortunately the only software on the market is a commercial program from Ridom. This article presents DNAGear, a free and open source software with a user friendly interface written all in Java on top of NetBeans Platform to perform spa typing, detecting new repeats and new spa types and synchronizing automatically the files with the open access database. The installation is easy and the application is platform independent. In fact, the SPA identification is a formal regular expression matching problem and the results are 100% exact. As the program is using Java embedded modules written over string manipulation of well established algorithms, the exactitude of the solution is perfectly established. DNAGear is able to identify the types of the S. aureus sequences and detect both new types and repeats. Comparing to manual processing, which is time consuming and error prone, this application saves a lot of time and effort and gives very reliable results. Additionally, the users do not need to prepare the forward-reverse sequences manually, or even by using additional tools. They can simply create them in DNAGear and perform the typing task. In short, researchers who do not have commercial software will benefit a lot from this

    To determine the accuracy of splenic artery peak systolic velocity (SPA-PSV) in predicting fetal hemoglobin (Hb) Bart's disease at mid-pregnancy among fetuses at risk. Pregnant women at risk of having a fetus with Hb Bart's disease were recruited into the study at 18 - 22 weeks of gestation and underwent SPA-PSV measurement before cordocentesis. The final diagnosis used as a gold standard was based on fetal hemoglobin typing using high performance liquid chromatography (HPLC). A total of 136 fetuses from 132 singleton pregnancies and 2 twin pregnancies were recruited into the study. The mean maternal age was 28.7 ± 5.4 years, the mean gestational age was 19.1 ± 1.02 weeks, and the incidence of Hb Bart's disease was 23.5 % (32 fetuses). Using SPA-PSV above 1.51 Multiple of Median (MoM) as a cut-off point, the sensitivity, specificity, positive predictive value and negative predictive value of SPA-PSV to identify affected fetuses was 84.4 % (32 from 36 cases), 98.1 %, 93.1 % and 95.3 % respectively. Nearly all normal fetuses had a normal SPA-PSV. SPA-PSV assessment at mid-pregnancy may be used as an adjunct method to identify fetuses with Hb Bart's disease with high, but not perfect, accuracy and may reduce the risk from unnecessary cordocentesis in some fetuses. © Georg Thieme Verlag KG Stuttgart · New York.

    2009-01-01

    The South Pole-Aitken (SPA) basin is an important target for absolute age-dating. Vertical and lateral impact mixing ensures that regolith within SPA will contain rock fragments from SPA itself, local impact craters, and faraway giant basins. About 20% of the regolith at any given site is foreign [1, 2], but much of this material will be cold ejecta, not impact melt. We calculated the fraction of contributed impact melt using scaling laws to estimate the amount and provenance of impact melt, demonstrating that SPA melt is the dominant impact melt rock (>70%) likely to be present. We also constructed a statistical model to illustrate how many randomly-selected impact-melt fragments would need to be dated, and with what accuracy, to confidently reproduce the impact history of a site. A detailed impact history becomes recognizable after a few hundred to a thousand randomly-selected marbles, however, it will be useful to have more information (e.g. compositional, mineralogical, remote sensing) to group fragments. These exercises show that SPA melt has a high probability of being present in a scoop sample and that dating of a few hundred to a thousand impact-melt fragments will yield the impact history of the SPA basin.

    2015-01-01

    Pulsed-field gel electrophoresis (PFGE) is the 'gold standard' for genotyping of methicillin-resistant Staphylococcus aureus (MRSA); however, the DiversiLab (DL) system, based on rep-PCR, is faster, simpler and could be better adapted to daily routine hospital work. We genotyped 100 MRSA isolates using PFGE, DL, and spa typing, and evaluated the discriminatory power of each technique and the correlation between them by Simpson's index(SI) and adjusted Rand coefficient (ARI), respectively. The isolates were from clinical samples from eight hospitals in Extremadura (Spain) during 2010. DL separated the 100 MRSA into 18 patterns, with 69% of the isolates grouped into four predominant patterns. spa typing reported 17 spa types, classifying 69% of MRSA into two major types (t067 and t002). PFGE revealed the existence of 27 patterns, gathering 54% of MRSA into three pulse types (E8a, E7a and E7b). SI values were 0.819, 0.726, 0.887 and 0.460 for DL, spa typing, PFGE and CC-BURP, respectively. ARI values of DL over PFGE, spa typing and CC-BURP were 0.151, 0.321 and 0.071, respectively. DL has less discriminatory power than PFGE but more than spa typing. The concordance of DL with PFGE is low, primarily because DL does not discriminate between the three predominant MRSA pulse types in our environment.

    Despite advances in pharmacological therapy, physical treatment continues to be important in the management of ankylosing spondylitis (AS). The objective of the present study was to evaluate the effects and tolerability of combined spa therapy and rehabilitation in a group of AS patients being treated with TNF inhibitors. Thirty AS patients attending the Rheumatology Unit of the University of Padova being treated with TNF inhibitors for at least 3 months were randomized and assessed by an investigator independent from the spa staff: 15 were prescribed 10 sessions of spa therapy (mud packs and thermal baths) and rehabilitation (exercises in a thermal pool) and the other 15 were considered controls. The patients in both groups had been receiving anti-TNF agents for at least three months. The outcome measures utilized were BASFI, BASDAI, BASMI, VAS for back pain and HAQ. The evaluations were performed in all patients at the entry to the study, at the end of the spa treatment, and after 3 and 6 months. Most of the evaluation indices were significantly improved at the end of the spa treatment, as well as at the 3 and 6 months follow-up assessments. No significant alterations in the evaluation indices were found in the control group. Combined spa therapy and rehabilitation caused a clear, long-term clinical improvement in AS patients being treated with TNF inhibitors. Thermal treatment was found to be well tolerated and none of the patients had disease relapse.

    2016-08-01

    In this review we focus on the role of SPA proteins in light signalling and discuss different aspects, including molecular mechanisms, specificity, and evolution. The ability of plants to perceive and respond to their environment is key to their survival under ever-changing conditions. The abiotic factor light is of particular importance for plants. Light provides plants energy for carbon fixation through photosynthesis, but also is a source of information for the adaptation of growth and development to the environment. Cryptochromes and phytochromes are major photoreceptors involved in control of developmental decisions in response to light cues, including seed germination, seedling de-etiolation, and induction of flowering. The SPA protein family acts in complex with the E3 ubiquitin ligase COP1 to target positive regulators of light responses for degradation by the 26S proteasome to suppress photomorphogenic development in darkness. Light-activated cryptochromes and phytochromes both repress the function of COP1, allowing accumulation of positive photomorphogenic factors in light. In this review, we highlight the role of the SPA proteins in this process and discuss recent advances in understanding how SPAs link light-activation of photoreceptors and downstream signaling.

    The main aim of the paper is to outline the perspective for future developments of the spa treatment in light of demographic transitions characterized by the increasing number of seniors, as well as changing expectations and health needs of younger population. We made a systematic review of literature referring to the experience of Poland, and similar experiences of other countries in Central Europe. Based on the existing knowledge we conclude that spa treatment should become one of the preferred directions of development of health systems in European countries. Moreover, we state that a desirable direction to modify the therapeutic paradigm used in spa treatment is to put a far-reaching greater emphasis on the provision of innovative health promotion, which is justified by both its effectiveness, and strongly good foundation for its provision in spas. For this purpose it is necessary to extend the specialized health sector personnel with qualified health educators, which will enable an effective implementation of health promotion actions and their proper alignment to the specific target groups. Developing this category of specialists will also enable other professionals to concentrate on therapeutic activity fitting their competence.

    To evaluate the medium-term impact of education workshops on low back pain (LBP) in the setting of a thermal spa on: fear-avoidance beliefs, disability, pain, and satisfaction. Randomized prospective alternate-month design-type study including 360 individuals having thermal spa therapy for LBP: 188 in the intervention group (three standardized education workshops lasting 1 h 30 each and usual thermal therapy for 3 weeks), 172 in the control group (usual thermal therapy and non-standardized verbal information). The principal analysis criterion was the difference in the fear-avoidance beliefs (physical FABQ) score between baseline and 6 months after the therapy; secondary criteria were: evolution of disability (Quebec Scale) and pain intensity (Visual Analogue Scale), and satisfaction with the information received. There was a significant reduction in the physical FABQ score at 6 months (Pspa therapy by reducing the effect of fear-avoidance beliefs as well as relieving pain. Extending the use of such workshops could contribute to enhance the positive impact of spa therapy in the management of chronic disabling diseases. Copyright © 2012 Société française de rhumatologie.

    Full Text Available Staphylococcus aureus, including methicillin-resistant S. aureus (MRSA, is an important human pathogen that produces a variety of toxins and causes a wide range of infections, including soft-tissue infections, bacteremia, and staphylococcal food poisoning. A loop-mediated isothermal amplification (LAMP assay targeting the arcC gene of S. aureus was developed and evaluated with 119 S. aureus and 25 non-S. aureus strains. The usefulness of the assay was compared with the PCR method that targets spa and arcC genes. The optimal temperature for the LAMP assay was 58.5°C with a detection limit of 2.5 ng/μL and 102 CFU/mL when compared to 12.5 ng/μL and 103 CFU/mL for PCR (spa and arcC. Both LAMP and PCR assays were 100% specific, 100% sensitive, 100% positive predictive value (PPV, and 100% negative predictive value (NPV. When tested on 30 spiked blood specimens (21 MRSA, eight non-S. aureus and one negative control, the performance of LAMP and PCR was comparable: 100% specific, 100% sensitive, 100% PPV, and 100% NPV. In conclusion, the LAMP assay was equally specific with a shorter detection time when compared to PCR in the identification of S. aureus. The LAMP assay is a promising alternative method for the rapid identification of S. aureus and could be used in resource-limited laboratories and fields.

    Identification of molecular interactions is paramount to understanding how cells function. Most available technologies rely on co-purification of a protein of interest and its binding partners. Therefore, they are limited in their ability to detect low-affinity interactions and cannot be applied to proteins that localize to difficult-to-solubilize cellular compartments. In vivo proximity labeling (IPL) overcomes these obstacles by covalently tagging proteins and RNAs based on their proximity in vivo to a protein of interest. In IPL, a heterobifunctional probe comprising a photoactivatable moiety and biotin is recruited by a monomeric streptavidin tag fused to a protein of interest. Following UV irradiation, candidate interacting proteins and RNAs are covalently biotinylated with tight spatial and temporal control and subsequently recovered using biotin as an affinity handle. Here, we describe experimental protocols to discover novel protein-protein and protein-RNA interactions using IPL. © 2017 by John Wiley & Sons, Inc. Copyright © 2017 John Wiley & Sons, Inc.

    Visible near spectra tecnnology was adopted to detect soil total nitrogen content. 394 soil samples were collected from Wencheng, Zhejiang province to be used for calibration model (n=263) and independent prediction set (n=131). Raw spectra and wavelength-reduced spectra with five different pretreatment methods (SG smoothing, SNV, MSC, 1st-D and 2nd-D) were compared to determine the optimal wavelength range and pretreatment method for analysis. The results with 5 different pretreatment methods were not improved compared to that both of full spectra PLS model and wavelength reduction spectra model. Spectral variable selection is an important strategy in spectrum modeling analysis, because it tends to parsimonious data representation and can lead to multivariate models with better performance. In order to simply calibration models, the wavelength variables selected by two different variable selection methods (i. e. regression coefficient analysis (RCA) and successive projections algorithm (SPA) were proposed to be the inputs of calibration methods of PLS, MLR and LS-SVM models separately. These calibration models were also compared to select the best model to predict soil TN. In total, 9 different models were built ahd the best results indicated that PLS, MLR and LS-SVM obtained the highest precision with determination coefficient of prediction R2(pre) =0. 81, RMSEP=0. 0031 and RPD=2. 26 based on wavelength variables selected by RCA (0. 0002) and SPA as inputs of models. SPA-MLR model and other three models based on 7 sensitive variables selected by RC using 0. 0002 regression coefficient threshold value obtained the best result with R2(pre), RMSEP and RPD as 0. 81, 0. 0031 and 2. 26. This prediction accuracy is classied to be very good. For all the models, it could be concluded that RCA and SPA could be very useful ways to selected sensitive wavelengths, and the selected wavelengths were effective to estimate soil TN. It is recommended to adopt SPA variable

    The emergence of methicillin-resistant Staphylococcus aureus (MRSA) has become an increasing problem worldwide in recent decades. Molecular typing methods have been developed to identify clonality of strains and monitor spread of MRSA. We compared a new commercially available DiversiLab (DL) repetitive element PCR system with spa typing, spa clonal cluster analysis, and pulsed-field gel electrophoresis (PFGE) in terms of discriminatory power and concordance. A collection of 106 well-defined MRSA strains from our hospital was analyzed, isolated between 1994 and 2006. In addition, we analyzed 6 USA300 strains collected in our institution. DL typing separated the 106 MRSA isolates in 10 distinct clusters and 8 singleton patterns. Clustering analysis into spa clonal complexes resulted in 3 clusters: spa-CC 067/548, spa-CC 008, and spa-CC 012. The discriminatory powers (Simpson's index of diversity) were 0.982, 0.950, 0.846, and 0.757 for PFGE, spa typing, DL typing, and spa clonal clustering, respectively. DL typing and spa clonal clustering showed the highest concordance, calculated by adjusted Rand's coefficients. The 6 USA300 isolates grouped homogeneously into distinct PFGE and DL clusters, and all belonged to spa type t008 and spa-CC 008. Among the three methods, DL proved to be rapid and easy to perform. DL typing qualifies for initial screening during outbreak investigation. However, compared to PFGE and spa typing, DL typing has limited discriminatory power and therefore should be complemented by more discriminative methods in isolates that share identical DL patterns.

    The plaque psoriasis, one of the most common form of psoriasis, is a chronic inflammatory disease. This pathology can cause devastating effects on quality of life and social relations with significant physical and psychological distress. Currently among the therapeutic agents available for the treatment of psoriasis is including SPA therapy, whose mechanism of action is only partially known, as well as very few studies examined the impact of this therapy on the quality of life. On the basis of these considerations, the research analyzed the effectiveness of SPA bath therapy (BLT) and its impact on quality of life and psychological distress in patients suffering from chronic plaque psoriasis. The study was conducted on 35 patients with chronic plaque psoriasis: 23% male and 77% female; mean age:56 ± 19 years; age range:17-85 years. The subjects were treated, for 2 weeks, with sulphureous SPA bath therapy from Terme of Telese SpA (Benevento-Italy). At the beginning and at the end of the SPA treatment considered was evaluated: the itching symptom (using NRS scale); the PASI Index; the impact on quality of life (using SF-36 and DLQI questionnaires) and on psychological distress (using ZUNG -tests). At the end of the SPA treatment, the mean values ± SD, compared to baseline, have showed a significant (p 1.0 ± 1.0) and PASI score (4 ± 4-->1.7 ± 2) with an improvement in quality of life and psichological distress as demonstrated by SF-36, DLQI and ZUNG tests. The data of this research show that the sulphureous SPA bath therapy can be considered very useful in patients with mild-to-moderate psoriasis for the improving of the quality of life and social relationship.

    Flagellar type III secretion systems (T3SS) contain an essential cytoplasmic-ring (C-ring) largely composed of two proteins FliM and FliN, whereas an analogous substructure for the closely related non-flagellar (NF) T3SS has not been observed in situ. We show that the spa33 gene encoding the putative NF-T3SS C-ring component in Shigella flexneri is alternatively translated to produce both full-length (Spa33-FL) and a short variant (Spa33-C), with both required for secretion. They associate in a 1:2 complex (Spa33-FL/C2) that further oligomerises into elongated arrays in vitro. The structure of Spa33-C2 and identification of an unexpected intramolecular pseudodimer in Spa33-FL reveal a molecular model for their higher order assembly within NF-T3SS. Spa33-FL and Spa33-C are identified as functional counterparts of a FliM-FliN fusion and free FliN respectively. Furthermore, we show that Thermotoga maritima FliM and FliN form a 1:3 complex structurally equivalent to Spa33-FL/C2 , allowing us to propose a unified model for C-ring assembly by NF-T3SS and flagellar-T3SS. © 2015 The Authors.

    Methicillin-resistant Staphylococcus aureus (MRSA) is a major cause of bacteraemia. We aimed to obtain a complete picture of severe MRSA infections by characterizing all MRSA isolates from bloodstream infections in the largest German federal state (North Rhine-Westphalia, 18 million inhabitants) using S. aureus protein A (spa) sequence-typing and antimicrobial susceptibility testing. MRSA isolates (n = 1952) were collected prospectively (2011-2013) and spa-typed. Among 181 different spa types, t003 (n = 746 isolates; 38.2%) and t032 (n = 594; 30.4%) were predominant. Analysis of the geographical occurrence of spa clonal complexes (spa-CCs) and spa types revealed divergent distribution between federal state districts for spa-CCs 003 (p spa type t2807 (p spa-CC011), for MRSA bacteraemia in some parts of the federal state. Susceptibility testing revealed broad resistance to substances used for oral treatment, but demonstrated that those antibiotics that are mostly applied for treatment of MRSA bacteraemia and important combination partners were highly susceptible.

    Staphylococcus aureus is a leading cause of bloodstream infections. For epidemiological investigations of this bacteria spa genotyping is used as the method which has a high discriminatory power and gives results that can be easily compared between laboratories. In contrast to methicillin-resistant S.aureus (MRSA), relatively little is known about spa types among methicillin-susceptible strains (MSSA). We used spa typing and antibiotic resistance patterns analysis for retrospective study of S.aureus bloodstream isolates population from the University Clinical Centre (UCC) in Gdańsk. The study was performed on 53 isolates from patients of 19 different units/ departments of the UCC. The isolates were tested for the susceptibility to antimicrobial agents. Spa typing was performed on the basis of the sequence analysis of the polymorphic X region of the protein A gene (spa) amplified form the isolates. Spa types were determined by Ridom Staph Type software and were clustered into spa-CCs (clonal complexes) using the algorithm BURP-based upon repeat pattern. MLST (Multilocus Sequence Typing) clonal complexes were predicted from BURP analysis by the Ridom SpaServer database. In MRSA the staphylococcal chromosomal casette (SCC) mec was determined, Spa-typing yielded 26 types. Six spa-CC and seven singletons were identified. The most frequent was spa-CC021involving 38% of isolates. The CC021 consisted of 7 spa types and the most common was t021 corresponding with MLST-CC30. The second frequent was singleton, related to MLST-CC1, with only one type t127. There were 3 MRSA isolates in the population. The MRSA strains were identified as different spa types: t003/ SCCmecII, t008/SCCmecIV and clonally related to MSSA t032/SCCmecIV. No one MRSA strains belonged to spa-CC021. The spa clonal cluster corresponding with widely distributed among invasive S.aureus strains in Europe MLST-CC30 was found as the most frequent among S.aureus bloodstream isolates from the UCC.

    Finger dislocations are common injuries that are often managed by emergency nurse practitioners. A systematic physical examination following these injuries is imperative to avoid complications. Radiographic views, including the anteroposterior, lateral, and oblique views, are imperative to evaluate these finger dislocations. A dorsal dislocation of the proximal interphalangeal (PIP) joint is the most common finger dislocation type often easily reduced. A volar PIP dislocation can often be difficult to reduce and may result in finger deformity. Finger dislocations should be reduced promptly. Referral to an orthopedic hand specialist is required if the dislocation is unable to be reduced or if the finger joint is unstable following reduction attempts.

    The proximity effect in diffusive normal-superconducting (NS) nano-structures is described by the Usadel equations for the electron pair correlations. We show that these equations obey a variational principle with a potential which generalizes the Ginzburg-Landau energy functional. We discuss simple examples of NS circuits using this formalism. In order to test the theoretical predictions of the Usadel equations, we have measured the density of states as a function of energy on a long N wire in contact with a S wire at one end, at different distances from the NS interface.

    Methicillin-resistant Staphylococcus aureus (MRSA) is a major nosocomial pathogen that causes a variety of infections. MRSA has evolved resistance to multiple antibiotics. Genetic background and virulence differs in different geographic regions. The present study was aimed to investigate the prevalence of enterotoxin genes and spa genotypes of hospital-associated methicillin-resistant Staphylococcus aureus (HA-MRSA) isolated from a tertiary care hospital of Jiangsu province, China. HA-MRSA isolates from August 2013 to April 2014 at a tertiary care hospital of China were collected. We investigated antimicrobial pattern, spa types, SCCmec types and the presence of 14 virulence genes. Eighty HA-MRSA isolates were collected. Results from SCCmec typing revealed that 73.8% were type II; 13.8% were type III; 12.5% were type V. There were 19 different spa types. Spa type t2460 was the most common (35.0%), followed by t002 (11.3%). CC5 was the predominant MLST CCs type (50%). The most frequent toxin genes were sea, seb, sed, sel, sen and seo (100.0%). None of the investigated isolates carried the sec or tst. Genotypic and virulence evaluation of the isolated HA-MRSA revealed that the isolates with CC5 and SCCmec II were the predominant type and highly homological. The virulence profiles mainly existed in the genes of sea, seb, sed, sel, sen, seo and ser. The prevalence of t2460 was an outbreak and the predominant spa type.

    Methicillin-resistant Staphylococcus aureus (MRSA) has been endemic in Hong Kong for three decades. This study evaluated the practical use of high-resolution melting (HRM) real-time PCR analysis on MRSA staphylococcal Protein A (spa) typing on local MRSA isolates. Among 55 clinical MRSA isolates collected in 2011, 12 different spa types were observed by the conventional PCR-sequencing method including the locally predominant spa type t1081 and two locally predominant community acquired MRSA spa types t019 and t437. By using the HRM method, it could differentiate all 12 spa genotypes by distinct melting curves and HRM difference plot analysis. These two methods demonstrated 100% concordance whereas the HRM method required only 3h of turnaround time and one-fifth of reagent cost compared to the conventional method. Our study confirmed that the cost effective and rapid HRM typing approach is practically useful for MRSA community transmission monitoring and nosocomial outbreak control in Hong Kong.

    The ability of impacts of all sizes to laterally transport ejected material across the lunar surface is well-documented both in lunar samples [1-4] and in remote sensing data [5-7]. The need to quantify the amount of lateral transport has lead to several models to estimate the scale of this effect. Such models have been used to assess the origin of components at the Apollo sites [8-10] or to predict what might be sampled by robotic landers [11-13]. Here we continue to examine the regolith inside the South Pole-Aitken Basin (SPA) and specifically assess the contribution to the SPA regolith by smaller craters within the basin. Specifically we asses the effects of four larger craters within SPA, Bose, Bhabha, Stoney, and Bellinsgauzen all located within the mafic enhancement in the center of SPA (Figure 1). The region around these craters is of interest as it is a possible landing and sample return site for the proposed Moon-Rise mission [14-17]. Additionally, understanding the provenance of components in the SPA regolith is important for interpreting remotely sensed data of the basin interior [18-20].

    Radon ({sup 222}Rn) levels in air and water have been analyzed continuously for almost a year in Las Caldas de Besaya thermal spa, north Spain. Radon is a naturally occurring noble gas from the decay of radium ({sup 226}Ra) both constituents of radioactive uranium 238 series. It has been recognized as a lung carcinogen by the World Health Organization (WHO) and International Agency for Research on Cancer (IARC). Furthermore the Royal Decree R.D 1439/2010 of November, 2010 establishes the obligation to study occupational activities where workers and, where appropriate, members of the public are exposed to inhalation of radon in workplaces such as spas. Together with radon measures several physico-chemical parameters were obtained such as pH, redox potential, electrical conductivity and air and water temperature. The devices used for the study of the temporal evolution of radon concentration have been the RTM 2100, the Radon Scout and gamma spectrometry was complementarily used to determine the transfer factor of the silicone tubes in the experimental device. Radon concentrations obtained in water and air of the spa are high, with an average of 660 Bq/l and 2900 Bq/m{sup 3} respectively, where water is the main source of radon in the air. Radiation dose for workers and public was estimated from these levels of radon. The data showed that the thermal processes can control the behavior of radon which can be also influenced by various physical and chemical parameters such as pH and redox potential. - Highlights: • Radon in water is the major source of indoor air radon concentration in thermal facilities. • Radon in water has been used to characterize the origin of water used for treatments in a spa. • Preliminary dose assessment from radon exposure has been performed.

    Our previous crossover randomized trial suggested that spa therapy added to usual pharmacotherapy provides benefits that lasted 6 months over pharmacotherapy alone in rheumatoid arthritis patients. We now extend, and report the long-term results of that study. In the crossover trial, patients were randomized to spa therapy first group or control first group (first assignment, period 1, 6 months); after this period and washout phase (9 months), they crossed over to the other arm (second assignment, period 2, 6 months). In this long-term study, we now analyze the 15-month results of the first assignment, and 12-month results of the second assignment in the opposite side with a 6-month extension of the follow-up period. The clinical outcome measures were pain, patient and physician global assessment, Health Assessment Questionnaire, and Disease Activity Score-28. The 15-month results of first assignment revealed no statistically significant differences between the groups in any of the efficacy outcomes (p > 0.05 for all). The 12-month results for the second assignment after crossover revealed a statistically significant decrease between the groups regarding the patient global assessment scores (p = 0.016), physician global assessment scores (p = 0.003) and swollen joints counts (p = 0.030); however, no statistically significant difference was found between the groups in any of the other efficacy outcomes (p > 0.05 for all). The short- and medium-term beneficial effects of the 2-week spa therapy added to the usual pharmacotherapy observed through the initial 6-month evaluation period may be maintained mildly to moderately to the 12-month mark in rheumatoid arthritis patients receiving conventional disease-modifying antirheumatic drugs. Further studies with a larger sample size are needed for the confirmation of the study results.

  2. Natural radioactivity in mineral and spa water: the current regulatory approach in Italy

    Mineral and thermal waters can contain radioactivity of natural origin which, in some cases, can lead to radiation-protection problems for both workers and consumers. In Italy, as in many other countries, the consumption of bottled mineral water is rather high and the practice of spending short stays in spas is also popular. Consumer protection against natural radioactivity in mineral water is not regulated at all and exposure from thermal waters is not treated in detail, in either the European Union or Italy. For this reason, the Italian Ministry of Health - which has the duty to authorize spa activities and the sale of mineral water on the basis of water characteristics - asked the Istituto Superiore di Sanita (the Italian National Institute of Health) to provide ad-hoc reports containing both dosimetric calculations and analysis of the radiation-protection regulations to be applied in these situations. On the basis of these reports, the Ministry of Health decided, in two statements for spa and mineral waters respectively, to indicate upper levels for natural radioactivity content. Since 2002, spa water parameters have been in force for authorization of their use and sale, and are to be promulgated by specific and more comprehensive regulations. For mineral waters used for infant feeding and drinking, levels lower than those for general public uses have been proposed, in order to take into account the higher ingestion dose coefficients for infants. At the moment, mineral water levels are not enforced as law. This paper presents the dosimetric calculation results and the Ministry of Health statements. (Author) 17 refs.

    In January 2014 an internal audit was performed at the department of surgery, division of vascular surgery of the Medical University Graz, Austria, to assess the short and long-term outcomes of prosthetic shunt graft implantations performed between December 1998 and December 2013. A 10.8 % explantation rate due to graft infection was detected. The majority of the cases were associated with Staphylococcus aureus . The aim of this study was to clarify whether this constitutes a nosocomial problem. Between December 1998 and December 2014 a total of 490 prosthetic shunt grafts were implanted. After exclusion of 54 cases, 436 shunts remained for statistical analysis. Genetic analysis (spa typing) was acquired from three new cases with involvement of S. aureus in 2014. The impact of several factors (e.g. sex, institute for dialysis, age, type of prosthesis, implantation surgeon and position of shunt) on the shunt graft infection rate was statistically analyzed. Of the prostheses 14.0 % (61 out of 436) had to be explanted of which 12.4 % (54/436) were due to infection. In 77.8 % (42/54) bacteria were found in blood and/or wound cultures. Staphylococcus aureus was present in 76.2 % (32/42) of the cases with detected bacteria and in all cases was sensitive to methicillin. The infection rate was not significantly dependent on any of the investigated factors; however, the factor "institute for dialysis" had a remarkable p‑value of 0.060 with the infection rate ranging from 8.5 % to 18.2 % depending on the institution. Three different S. aureus protein A (spa) types were found: t015, t359, t6265. The detection of three different spa types means that these patients had different sources of S. aureus so that a nosocomial problem is very unlikely. Genetic typing of spa is a suitable technique for distinguishing between nosocomial and community acquired sources of prosthetic shunt graft infections.

    Methicillin-resistant S. aureus (MRSA) of clonal complex 398 (CC398) is emerging globally among production animals such as cattle, pigs and poultry as well as among humans. However, little is known about the prevalence of CC398 among methicillin sensitive S. aureus (MSSA) or the relative clonal...... distribution of S. aureus isolated from these three animal reservoirs. To study this, we have analyzed a random sample of S. aureus consisting of 296 epidemiologically unrelated isolates from infections and colonisation of pigs, cattle and poultry. These were examined and compared by spa and multi...

    The purpose of this study was to clarify the effect of stone spa bathing (Ganban-yoku) and hot-spring bathing on brachial-ankle pulse wave velocity (baPWV) in healthy, late middle-aged females. The subjects were 13 females (mean age, 47.3 years). The skin and tympanic temperatures, blood pressure, and baPWV were measured before and after stone spa bathing and hot-spring bathing. For the stone spa bathing, the subjects lay down three times for approximately 10 min each time over warm stone beds. Although body weight showed no change after the hot-spring bathing, it significantly increased after the stone spa bathing. The increase was significantly related to the amount of water intake. The skin and tympanic temperatures increased to a smaller degree after the stone spa bathing than after the hot-spring bathing. The diastolic blood pressure decreased to a smaller degree after the stone spa bathing. BaPWV showed no significant change after bathing both in the stone spa and in the hot-spring. The results of multiple regression analysis showed that the factors significantly related to the change in baPWV after the stone spa bathing were the changes in skin and tympanic temperatures and habit of smoking, and that after the hot-spring bathing was the change in skin temperature. The results suggest that, compared with the hot-spring bathing, stone spa bathing causes less strain on the body. The stone spa bathing and hot-spring bathing showed no marked effect on baPWV. However, there is a possibility that the stone spa bathing may be used as a load for investigating arterial stiffness.

    Staphylococcus aureus nasal carriers risk autoinfection; however, knowledge about the factors that make specific strains successful colonizers is limited. This study was undertaken to identify the most successful S. aureus clones in nasal carriers and compare their distribution among host groups. The population structure of S. aureus isolates from healthy adults was investigated by spa typing 1,981 isolates from persistent and intermittent nasal carriers participating in a health survey. In the baseline screening (1,113 isolates), the most common spa types were t012 (8.4%), t084 (7.6%), and t065 (4.9%). Three large spa clonal complexes (spa CC012, spa CC065, and spa CC084) comprised 62.4% of the isolates. In multivariate models adjusted for age and smoking status, male sex was associated with higher risk for spa type t084 (odds ratio [OR], 1.72; 95% confidence interval [CI], 1.06 to 2.77), and lower risk of spa type t012 (OR, 0.60; 95% CI, 0.39 to 0.92) colonization. The prevalence of spa type t012 decreased significantly with increasing age (P = 0.03), with a prevalence almost twice as high in the youngest group (age 30 to 44 years, prevalence = 11.1%) as in the oldest group (age, 60 to 87 years; prevalence = 5.6%). Among baseline isolates, spa type t084 had a twofold-higher prevalence among intermittent carriers than among persistent carriers (10.6% versus 5.5%; P = 0.04). In summary, the two most prevalent spa types found in this study were significantly associated with age and/or gender. This may provide valuable clues to the multifactorial mechanisms, among them bacterial factors, involved in nasal colonization with S. aureus.

    The South Pole Aitken (SPA) basin is the stratigraphically oldest identifiable lunar basin and is therefore one of the most important targets for absolute age-dating to help understand whether ancient lunar bombardment history smoothly declined or was punctuated by a cataclysm. A feasible near-term approach to this problem is to robotically collect a sample from near the center of the basin, where vertical and lateral mixing provided by post-basin impacts ensures that such a sample will be composed of small rock fragments from SPA itself, from local impact craters, and from faraway giant basins. The range of ages, intermediate spikes in the age distribution, and the oldest ages are all part of the definition of the absolute age and impact history recorded within the SPA basin.

    Necrosis of the humeral head, infections and non-unions are among the most dangerous and difficult-to-treat complications of proximal humeral fractures. The aim of this work was to analyse in detail non-unions and post-traumatic bone defects and to suggest an algorithm of care. Treatment options are based not only on the radiological frame, but also according to a detailed analysis of the patient, who is classified using a risk factor analysis. This method enables the surgeon to choose the most suitable treatment for the patient, thereby facilitating return of function in the shortest possible time. The treatment of such serious complications requires the surgeon to be knowledgeable about the following possible solutions: increased mechanical stability; biological stimulation; and reconstructive techniques in two steps, with application of biotechnologies and prosthetic substitution.

    Antonelli, Michele; Donelli, Davide

    2018-02-18

    Balneotherapy and spa therapy are well-known practices, even though limited evidence has been produced about their biological effects. This systematic review primarily aims at assessing if balneotherapy, mud/peloid therapy, and spa therapy may influence cortisol levels. Secondarily, it aims at understanding if these interventions may improve stress resilience. PubMed/Medline, Embase, and Cochrane Library were searched for relevant articles in English or Italian about studies involving healthy and sub-healthy subjects or patients with a diagnosed disease about effects of balneotherapy, mud/peloid therapy, and spa therapy on serum and salivary cortisol levels. Fifteen studies involving 684 subjects were included. Five studies investigated biological effects of balneotherapy alone. Two of them reported significant changes of cortisol levels in healthy participants. The other three studies reported no significant variations in patients with rheumatic conditions. No studies investigated biological effects of mud/peloid therapy alone. Ten studies investigated biological effects of spa therapy with or without included mud/peloid therapy, and in all but two studies, significant variations of cortisol levels were reported. Our main findings suggest that balneotherapy may have the potential to influence cortisol levels in healthy subjects, in such a way as to improve stress resilience. Spa therapy with or without included mud/peloid therapy demonstrated the same potential to influence cortisol levels also in sub-healthy subjects and in patients with a diagnosed disease. Therefore, balneotherapy and spa therapy may be considered as useful interventions for the management of stress conditions. Further investigation is needed because of limited available data.

    In most European countries, balneotherapy and spa therapy are widely prescribed by physicians and preferred by European citizens for the treatment of musculoskeletal problems including chronic low back pain (LBP). We aimed to review and evaluate the recent evidence on the effectiveness of balneotherapy and spa therapy for patients with LBP. We comprehensively searched data bases for randomized controlled trials (RCTs) published in English between July 2005 and December 2013. We identified all trials testing balneotherapy or spa therapy for LBP that reported that the sequence of allocation was randomized. We finally included total of eight RCTs: two on balneotherapy and six on spa therapy. All reviewed trials reported that balneotherapy was superior in long term to tap water therapy in relieving pain and improving function and that spa therapy combining balneotherapy with mud pack therapy and/or exercise therapy, physiotherapy, and/or education was effective in the management of low back pain and superior or equally effective to the control treatments in short and long terms. We used Jadad scale to grade the methodological quality. Only three out of total eight had a score of above 3 indicating the good quality. The data from the RCTs indicates that overall evidence on effectiveness of balneotherapy and spa therapy in LBP is encouraging and reflects the consistency of previous evidence. However, the overall quality of trials is generally low. Better quality RCTs (well designed, conducted, and reported) are needed testing short- and long-term effects for relieving chronic back pain and proving broader beneficial effects.

    Full Text Available Application of bioclimatic parameters in the design of tourist objects is an important factor for reducing energy consumption and preserving the environment. It represents the response to constant changing of climate conditions. Given the fact that development of tourism has negative consequences on the environment, it is necessary to examine the way design process can affect the reduction of energy and environmental pollution. This paper analyzes the principles of bioclimatic planning and design of the Spa Center at the Balkan Mountain that is one of the most valuable ecosystems in Serbia. Adaptation to the existing climate change was analyzed on two levels. The first level was urban factors that include analysis of local climate and environment that affect the positioning of the object and preliminary form. The second level was architecture factors with technical and technological solutions that can be achieved through the application of climate and energy responsible designing. Final analyses indicate that the bioclimatic approach is necessary in the initial stage of setting preliminary design for the building, because later it would take more effort to install technology that requires time and the whole process makes much more expensive. The work indicates that the energy needs of optimized Spa center like represented, from the very beginning of planning and designing, can be drastically reduced.

    Full Text Available Modern civilization moves to endless automation and mechanization. This fact, in one hand, has positive effect on increase of life standard, but also carries its own risks and threats of mankind. Axelberg, famous academician, makes an interesting remark that only a hundred years ago man did 96 % of his work by himself, while today most manufacturing processes are 100% automated. Stress, lack of physical activity and bad food regime are canses of organic damages of cardiopulmonary system. Latest research, conducted in many countries, shows that for proper functioning of every organism the minimum of moving is necessary.Term neurosis was introduced in medical literature by Scottish doctor W. Cullen in 1777. By that term were considered different clinical appearances which are believed neurotic todey, but also the phenomena today considered as psychosomatic disorders of character and behavior. Pavlov’s reflexive theory is basic in treatment of some types of neurossis’ during spa treatments in Nerečinska Banja. It usually starts at the beginning of May and ends in October, but sometimes if weather is nice, it can last until the middle of November. The treatment cure last tventy-one day, doesn’t include medicaments, but only spa water, baths and massage.

    Since 2012, low-to-moderate mortality associated with an Erysipelothrix sp. bacterium has been reported in ornamental fish. Histological findings have included facial cellulitis, necrotizing dermatitis and myositis, and disseminated coelomitis with abundant intralesional Gram-positive bacterial colonies. Sixteen Erysipelothrix sp. isolates identified phenotypically as E. rhusiopathiae were recovered from diseased cyprinid and characid fish. Similar clinical and histological changes were also observed in zebrafish, Danio rerio, challenged by intracoelomic injection. The Erysipelothrix sp. isolates from ornamental fish were compared phenotypically and genetically to E. rhusiopathiae and E. tonsillarum isolates recovered from aquatic and terrestrial animals from multiple facilities. Results demonstrated that isolates from diseased fish were largely clonal and divergent from E. rhusiopathiae and E. tonsillarum isolates from normal fish skin, marine mammals and terrestrial animals. All ornamental fish isolates were PCR positive for spaC, with marked genetic divergence (ornamental fish isolates and other Erysipelothrix spp. isolates. This study supports previous work citing the genetic variability of Erysipelothrix spp. spa types and suggests isolates from diseased ornamental fish may represent a genetically distinct species. © 2017 John Wiley & Sons Ltd.

    A system of medical weather forecast for the Caucasian Mineral Waters spa-and-resort complex has been modified and updated based on the results of long-term observations of weather conditions in the region of interest with special reference to the bioclimatic regime, atmospheric circulation, aerosol pollution of the near-ground air, ultraviolet radiation, heliomagnetic activity, and meteopathic effects. This system provides a basis for the timely emergency meteopreventive treatment of meteodependent patients and therefore can be instrumental in enhancing efficiency of spa-and-resort rehabilitative therapy.

    To investigate the accuracy and reliability of the Cobb angle, the spinous process angle (SPA), and apical vertebral rotation (AVR) for measuring adolescent idiopathic scoliosis (AIS), and to evaluate the correlations between these measurements. A retrospective study of two sets of standing posteroanterior radiographs of patients with AIS was performed. The first set was 59 consecutive patients with AIS with Cobb angles 45°. The Cobb angle, SPA and AVR of each curve was measured twice by three observers with varying measurement experience. The mean absolute difference, standard deviation, and intra- and inter-rater reliability coefficients for each measurement were examined. The Pearson correlation coefficients between any two parameters were reported. The association of the Cobb angle with the SPA and AVR was examined using a multiple regression model. The average intra- and inter-observer reliabilities (ICC [2, 1]) of the Cobb angle, SPA, and AVR were 0.99, 0.95, 0.92 and 0.98, 0.88, 0.83, respectively. The correlation coefficients (r) between Cobb angle and SPA, Cobb angle and AVR, and SPA and AVR were 0.93, 0.68, and 0.60, respectively. Using multiple regression, the association between the Cobb angle and SPA combined with AVR was R (2) = 0.90. The resulting regression model was: [Formula: see text]. The SPA has high correlation with the Cobb angle. Including the AVR as an additional factor in multiple regression improves the prediction of the Cobb angle.

    Plants have evolved light sensing mechanisms to optimally adapt their growth and development to the ambient light environment. The COP1/SPA complex is a key negative regulator of light signaling in the well-studied dicot Arabidopsis thaliana. COP1 and members of the four SPA proteins are part of an E3 ubiquitin ligase that acts in darkness to ubiquitinate several transcription factors involved in light responses, thereby targeting them for degradation by the proteasome. While COP1 is also found in humans, SPA proteins appear specific to plants. Here, we have functionally addressed evolutionary conservation of COP1 and SPA orthologs from the moss Physcomitrella, the monocot rice and the dicot Arabidopsis. To this end, we analyzed the activities of COP1- and SPA-like proteins from Physcomitrella patens and rice when expressed in Arabidopsis. Expression of rice COP1 and Physcomitrella COP1 protein sequences predominantly complemented all phenotypic aspects of the viable, hypomorphic cop1-4 mutant and the null, seedling-lethal cop1-5 mutant of Arabidopsis: rice COP1 fully rescued the constitutive-photomorphogenesis phenotype in darkness and the leaf expansion defect of cop1 mutants, while it partially restored normal photoperiodic flowering in cop1. Physcomitrella COP1 partially restored normal seedling growth and flowering time, while it fully restored normal leaf expansion in the cop1 mutants. In contrast, expression of a SPA ortholog from Physcomitrella (PpSPAb) in Arabidopsis spa mutants did not rescue any facet of the spa mutant phenotype, suggesting that the PpSPAb protein is not functionally conserved or that the Arabidopsis function evolved after the split of mosses and seed plants. The SPA1 ortholog from rice (OsSPA1) rescued the spa mutant phenotype in dark-grown seedlings, but did not complement any spa mutant phenotype in light-grown seedlings or in adult plants. Our results show that COP1 protein sequences from Physcomitrella, rice and Arabidopsis have

    To determine whether spa therapy has a beneficial effect on pain and disability in patients with chronic shoulder pain, this single-blind randomised controlled clinical trial included patients with chronic shoulder pain due to miscellaneous conditions attending one of four spa centres as outpatients. Patients were randomised into two groups: spa therapy (18 days of standardised treatment combining thermal therapy together with supervised mobilisation in a thermal pool) and controls (spa therapy delayed for 6 months: 'immediate versus delayed treatment' paradigm). All patients continued usual treatments during the 6-month follow-up period. The main endpoint was the mean change in the French-Quick DASH (F-QD) score at 6 months. The effect size of spa therapy was calculated, and the proportion of patients reaching minimal clinically important improvement (MCII) was compared. Secondary endpoints were the mean change in SF-36, treatment use and tolerance. One hundred eighty-six patients were included (94 patients as controls, 92 in the spa group) and analysed by intention to treat. At 6 months, the mean change in the F-QD score was statistically significantly greater among spa therapy patients than controls (- 32.6 versus - 8.15%; p spa therapy patients reached MCII (59.3 versus 17.9%). Spa therapy was well tolerated with a significant impact on SF-36 components but not on drug intake. Spa therapy provided a statistically significant benefit on pain, function and quality of life in patients with chronic shoulder pain after 6 months compared with usual care.

    We investigated the applicability of the Gestalt principle of perceptual grouping by proximity in the haptic modality. To do so, we investigated the influence of element proximity on haptic contour detection. In the course of four sessions ten participants performed a haptic contour detection task in which they freely explored a haptic random dot display that contained a contour in 50% of the trials. A contour was defined by a higher density of elements (raised dots), relative to the background surface. Proximity of the contour elements as well as the average proximity of background elements was systematically varied. We hypothesized that if proximity of contour elements influences haptic contour detection, detection will be more likely when contour elements are in closer proximity. This should be irrespective of the ratio with the proximity of the background elements. Results showed indeed that the closer the contour elements were, the higher the detection rates. Moreover, this was the case independent of the contour/background ratio. We conclude that the Gestalt law of proximity applies to haptic contour detection. PMID:23762364

    Staphylococcus aureus is a pathogen associated a different kind of infection. Molecular markers are useful tools to study microbial epidemiology. Twenty two methicillin-resistant S. aureus (MRSA) and 23 methicillin-susceptible S. aureus (MSSA) were studied by mecA gene, SCCmec cassette, Panton Valentine leucocidin (PVL) and spa polymorphism. The clinical data patients were analyzed. MSSA was prevalent in samples different from skin and soft tissue (SST) and in hospitalized patients, whereas MRSA in SST. SCCmec type IV was predominant, followed by type I. Low presence of PVL was found. In MRSA 11 different types of spa were detected, t019 was the most frequent and associated with outpatient, 17 types were found in MSSA and t189 was prevalent. spa t002 was present in MSSA and MRSA. We found 11 types of spa not reported in our country. Copyright © 2017 Asociación Argentina de Microbiología. Publicado por Elsevier España, S.L.U. All rights reserved.

    Oxidative stress has been shown to play a contributory role in the pathogenesis of rheumatoid arthritis (RA). Recent studies have provided evidence for antioxidant properties of spa therapy. The purpose of this study is to investigate whether spa therapy with saline balneotherapy has any influence on the oxidant/antioxidant status in patients with RA and to assess clinical effects of spa therapy. In this investigator-blind randomized controlled trial, we randomly assigned 50 patients in a 1:1 ratio to spa therapy plus standard drug treatment (spa group) or standard drug treatment alone (control group). Spa group followed a 2-week course of spa therapy regimen consisting of a total of 12 balneotherapy sessions in a thermal mineral water pool at 36-37 °C for 20 min every day except Sunday. All clinical and biochemical parameters were assessed at baseline and after spa therapy (2 weeks). The clinical parameters were pain intensity, patient global assessment, physician global assessment, Health Assessment Questionnaire disability index (HAQ-DI), Disease Activity Score for 28-joints based on erythrocyte sedimentation rate (DAS28-4[ESR]). Oxidative status parameters were malondialdehyde (MDA), nonenzymatic superoxide radical scavenger activity (NSSA), antioxidant potential (AOP), and superoxide dismutase (SOD). The NSSA levels were increased significantly in the spa group ( p = 0.003) but not in the control group ( p = 0.509); and there was a trend in favor of spa therapy for improvements in NSSA levels compared to control ( p = 0.091). Significant clinical improvement was found in the spa group compared to the control in terms of patient global assessment ( p = 0.011), physician global assessment ( p = 0.043), function (HAQ-DI) ( p = 0.037), disease activity (DAS28-4[ESR]) (0.044) and swollen joint count (0.009), and a trend toward improvement in pain scores (0.057).

    Proximal ulna fractures account for 20% of all proximal forearm fractures. Many treatment options are available for such fractures, such as cast immobilisation, plate and screw fixation, tension band wiring and intramedullary screw fixation, depending on the fracture pattern. Due to the subcutaneous nature of the proximal forearm, it is vulnerable to open injuries over the dorsal aspect of the proximal ulna. This may in turn prove challenging, as it is critical to obtain adequate soft tissue coverage to reduce the risk of implant exposure and bony infections. We herein describe a patient with a Gustillo III-B open fracture of the proximal ulna, treated with minimally invasive intramedullary screw fixation using a 6.0-mm cannulated headless titanium compression screw (FusiFIX, Péronnas, France).

    Aim of the study is to explore in shiftworkers: a) blood pressure and hormonal variations; b) dyslipidemia and blood glucose levels; c) insulin resistence syndrome. We have assessed 48 male workers employes in Amsa SpA, a large municipal enterprise in charge of street cleaning and domestic waste collection, in permanent day and night work as hand sweepers, motor sweepers and delivery tricar drivers. 24 of those workers (daily and nightly) were normotensive and 24 were hypertensive. Our medical checks were: physical examination: BMI; laboratory findings (blood): glucose, total cholesterol, triglycerides, endothelin, insulin, FFA, HOMA S, HOMA B, HOMA R; assay of salivary cortisol and urinary cortisol in 24 h; 24 h pressure monitoring. Nightly hypertensive: increased consumption in wine and coffee, weight and BMI, total cholesterol and FFA and endothelin. Nightly normotensive: increased consumption in cigarettes and salivary cortisol. Daily hypertensive: increased total cholesterol; 24 h pressure monitoring showed more pronounced variations of pressure in night workers both normotensive and hypertensive in working time. Night shiftwork looks like more stressfull than day shiftwork. Insuline resistance isn't noticed in all four groups.

    Full Text Available One balneological resource of extraordinary value, to which the town of Sandanski owes its existence, are the mineral waters. Within the whole region their total discharge is estimated at 65 1/s while for the town of Sandanski only it is about 25 1/s. Their temperature varies from 33°C to 88°C and the mineral content in them is poor - 0.78-1.02 g/1. That is why diseases can be treated both by drinking the water and by bathing. Besides its diverse natural scenery the Sandanski spa is famous for its important historical events. Melnik is a real monument of the Bulgarian culture. It is designated as a cultural and historical reserve and a museum town and has got the status of a unique settlement of international importance for economic tourism.

    Full Text Available The aim of this paper is to analyze the key features of an effective complaint management process as well as to explore whether these systems are formally constituted in terms of standards or other models for complaints management. We use four case studies of spa organizations from Spain. The case studies illustrate the organizations' approach to managing complaints and customer satisfaction effectively. The results of this exploratory study show that all four organizations have some mechanisms implemented to handle complaints although different levels of formalization have been achieved. The analysis unveils some common difficulties and key success factors of implementing a complaints handling system. The results of this paper suggest that managers should prioritize managing customer complaints effectively in order to enhance their chances of meeting customer expectations. This strategy can result into turning customer complaints to customer satisfaction, especially when the organization views complaints as an opportunity to improve.

    The aim of this study is to determine the effects of a combination treatment with etanercept and spa rehabilitation versus etanercept alone on function, disability and quality of life in a group of patients with active ankylosing spondylitis (AS). Sixty patients with AS underwent etanercept as suggested by ASAS/EULAR recommendations. As the clinical and laboratory conditions improved, 30 patients accepted the proposal of coupling the medical therapy with a 7-day rehabilitation program in a thermal baths centre; the remaining 30 subjects continued to take the biologic agent alone. The comparisons between the 2 groups were made after 3 and 6 months. The primary outcome was an improvement in BASFI. The secondary outcome was an improvement in the visual analogic scale of EuroQol (EQ-5Dvas). After 6 months a statistically significant improvement in BASFI (p intensive rehabilitation program contributes to disability reduction and ameliorates quality of life for AS patients.

    The function of pulmonary surfactant is affected by lung transplantation, contributing to impaired lung transplant function. A decreased amount of surfactant protein-A (SP-A) after reperfusion is believed to contribute to the impaired surfactant function. Surfactant treatment has been shown to improve lung transplant function, but the effect is variable. We investigated whether SP-A enrichment of surfactant improved the efficacy of surfactant treatment in lung transplantation. Left and right lungs of Lewis rats, inflated with 50% O2, were stored for 20 hr at 8 degrees C. Surfactant in bronchoalveolar lavage fluid from right lungs was investigated after storage (n=6). Left lungs were transplanted into syngeneic recipients and treated with SP-A-deficient surfactant (n=6) or SP-A-enriched surfactant (n=6) just before reperfusion. Air was instilled into untreated lung transplants (n=6). Sham operated (n=4) and normal (n=8) animals served as controls. Lung function was measured during 1 hr of reperfusion; surfactant components in bronchoalveolar lavage fluid were measured after reperfusion. After storage the amount of SP-A decreased by 27%, whereas surfactant phospholipids changed minimally. After reperfusion a further decrease of SP-A was paralleled by profound changes in surfactant phospholipids. Lung transplant function, however, remained relatively good. After instillation of SP-A-enriched surfactant, PO2 values were reached that approximated sham control PO2 values, whereas after SP-A-deficient surfactant treatment, the PO2 values did not improve. Enrichment of surfactant with SP-A for treatment of lung transplants improves the efficacy of surfactant treatment.

    Radon ((222)Rn) levels in air and water have been analyzed continuously for almost a year in Las Caldas de Besaya thermal spa, north Spain. Radon is a naturally occurring noble gas from the decay of radium ((226)Ra) both constituents of radioactive uranium 238 series. It has been recognized as a lung carcinogen by the World Health Organization (WHO) and International Agency for Research on Cancer (IARC). Furthermore the Royal Decree R.D 1439/2010 of November, 2010 establishes the obligation to study occupational activities where workers and, where appropriate, members of the public are exposed to inhalation of radon in workplaces such as spas. Together with radon measures several physico-chemical parameters were obtained such as pH, redox potential, electrical conductivity and air and water temperature. The devices used for the study of the temporal evolution of radon concentration have been the RTM 2100, the Radon Scout and gamma spectrometry was complementarily used to determine the transfer factor of the silicone tubes in the experimental device. Radon concentrations obtained in water and air of the spa are high, with an average of 660 Bq/l and 2900 Bq/m(3) respectively, where water is the main source of radon in the air. Radiation dose for workers and public was estimated from these levels of radon. The data showed that the thermal processes can control the behavior of radon which can be also influenced by various physical and chemical parameters such as pH and redox potential.

    Fifteen sequences with stop codons have been obtained in the course of standard methicillin-resistant Staphylococcus aureus (MRSA) spa typing. In nine of those sequences, stop codons occurred due to nonsense G-T and A-T transversions. G-T transversions would appear to be frequent in the spa gene, mostly due to symmetric mutational AT-pressure in the whole S. aureus genome and due to replication-associated mutational pressure characteristic of lagging strands of the "chromosome". A-T transversions would appear to be frequent in the spa gene mostly due to transcription-associated mutational pressure. Relative to other S. aureus genes, short repeats in spa are enriched by nonsense sites for G-T and A-T transversions; the probability of being nonsense for A-T transversion is high in that part of spa coding region. 13 out of 15 (87%) of the sequences with stop codons were obtained from strains isolated from patients with generalized S. aureus infection. Truncation of spa at its C-terminus is predicted to result in a protein that possesses functional IgG binding domains unable to be linked to the cell wall. This is discussed in light of the known fact that extracellular spa is a strong virulence factor involved in immune evasion. Copyright © 2013 Institut Pasteur. Published by Elsevier Masson SAS.

  14. Proximal Alternating Direction Method with Relaxed Proximal Parameters for the Least Squares Covariance Adjustment Problem

    Directory of Open Access Journals (Sweden)

    Minghua Xu

    2014-01-01

    Full Text Available We consider the problem of seeking a symmetric positive semidefinite matrix in a closed convex set to approximate a given matrix. This problem may arise in several areas of numerical linear algebra or come from finance industry or statistics and thus has many applications. For solving this class of matrix optimization problems, many methods have been proposed in the literature. The proximal alternating direction method is one of those methods which can be easily applied to solve these matrix optimization problems. Generally, the proximal parameters of the proximal alternating direction method are greater than zero. In this paper, we conclude that the restriction on the proximal parameters can be relaxed for solving this kind of matrix optimization problems. Numerical experiments also show that the proximal alternating direction method with the relaxed proximal parameters is convergent and generally has a better performance than the classical proximal alternating direction method.

  15. Enhanced discrimination of highly clonal ST22-methicillin-resistant Staphylococcus aureus IV isolates achieved by combining spa, dru, and pulsed-field gel electrophoresis typing data.

    LENUS (Irish Health Repository)

    Shore, Anna C

    2010-05-01

    ST22-methicillin-resistant Staphylococcus aureus type IV (ST22-MRSA-IV) is endemic in Irish hospitals and is designated antibiogram-resistogram type-pulsed-field group (AR-PFG) 06-01. Isolates of this highly clonal strain exhibit limited numbers of pulsed-field gel electrophoresis (PFGE) patterns and spa types. This study investigated whether combining PFGE and spa typing with DNA sequencing of the staphylococcal cassette chromosome mec element (SCCmec)-associated direct repeat unit (dru typing) would improve isolate discrimination. A total of 173 MRSA isolates recovered in one Irish hospital during periods in 2007 and 2008 were investigated using antibiogram-resistogram (AR), PFGE, spa, dru, and SCCmec typing. Isolates representative of each of the 17 pulsed-field group 01 (PFG-01) spa types identified underwent multilocus sequence typing, and all isolates were ST22. Ninety-seven percent of isolates (168 of 173) exhibited AR-PFG 06-01 or closely related AR patterns, and 163 of these isolates harbored SCCmec type IVh. The combination of PFGE, spa, and dru typing methods significantly improved discrimination of the 168 PFG-01 isolates, yielding 65 type combinations with a Simpson\\'s index of diversity (SID) of 96.53, compared to (i) pairwise combinations of spa and dru typing, spa and PFGE typing, and dru and PFGE typing, which yielded 37, 44, and 43 type combinations with SIDs of 90.84, 91.00, and 93.57, respectively, or (ii) individual spa, dru, and PFGE typing methods, which yielded 17, 17, and 21 types with SIDs of 66.9, 77.83, and 81.34, respectively. Analysis of epidemiological information for a subset of PFG-01 isolates validated the relationships inferred using combined PFGE, spa, and dru typing data. This approach significantly enhances discrimination of ST22-MRSA-IV isolates and could be applied to epidemiological investigations of other highly clonal MRSA strains.

  16. Microbead agglutination based assays

    KAUST Repository

    Kodzius, Rimantas

    2013-01-21

    We report a simple and rapid room temperature assay for point-of-care (POC) testing that is based on specific agglutination. Agglutination tests are based on aggregation of microbeads in the presence of a specific analyte thus enabling the macroscopic observation. Such tests are most often used to explore antibody-antigen reactions. Agglutination has been used for protein assays using a biotin/streptavidin system as well as a hybridization based assay. The agglutination systems are prone to selftermination of the linking analyte, prone to active site saturation and loss of agglomeration at high analyte concentrations. We investigated the molecular target/ligand interaction, explaining the common agglutination problems related to analyte self-termination, linkage of the analyte to the same bead instead of different microbeads. We classified the agglutination process into three kinds of assays: a two- component assay, a three-component assay and a stepped three- component assay. Although we compared these three kinds of assays for recognizing DNA and protein molecules, the assay can be used for virtually any molecule, including ions and metabolites. In total, the optimized assay permits detecting analytes with high sensitivity in a short time, 5 min, at room temperature. Such a system is appropriate for POC testing.

    The practice of proximal formative assessment - the continual, responsive attention to students' developing understanding as it is expressed in real time - depends on students' sharing their ideas with instructors and on teachers' attending to them. Rogerian psychology presents an account of the conditions under which proximal formative assessment may be promoted or inhibited: (1) Normal classroom conditions, characterized by evaluation and attention to learning targets, may present threats to students' sense of their own competence and value, causing them to conceal their ideas and reducing the potential for proximal formative assessment. (2) In contrast, discourse patterns characterized by positive anticipation and attention to learner ideas increase the potential for proximal formative assessment and promote self-directed learning. We present an analysis methodology based on these principles and demonstrate its utility for understanding episodes of university physics instruction.

    The transport of ammonia in the proximal tubule is a complex interaction of a number of processes. Ammonia transport in the proximal tubule is clearly bidirectional; ammonia is secreted into the early proximal tubule lumen, but later in the proximal tubule, efflux out of the lumen may result in net ammonia reabsorption. Two mechanisms of ammonia transport have clearly been established: NH3 diffusion and NH4+ transport on the Na(+)-H+ exchanger. The relative contribution of these pathways to ammonia transport is still unsettled. Other pathways for ammonia transport, particularly NH4+ efflux out of the lumen, may be important as well. A variety of factors may modulate ammonia transport: plasma, cell and luminal pH, luminal flow rate, luminal potassium, and angiotensin II. Each of these factors also alters ammonia production rates and in most circumstances, ammonia transport appears to follow ammonia production rates.

    1998-01-01

    Lockheed Martin Energy Research Corporation (LMERC) and Merritt Systems, Inc. (MSI) entered into a Cooperative Research and Development Agreement (CRADA) for the development and demonstration of a compact, modular proximity sensing system suitable for application to a wide class of manipulator systems operated in support of environmental restoration and waste management activities. In teleoperated modes, proximity sensing provides the manipulator operator continuous information regarding the proximity of the manipulator to objects in the workspace. In teleoperated and robotic modes, proximity sensing provides added safety through the implementation of active whole arm collision avoidance capabilities. Oak Ridge National Laboratory (ORNL), managed by LMERC for the United States Department of Energy (DOE), has developed an application specific integrated circuit (ASIC) design for the electronics required to support a modular whole arm proximity sensing system based on the use of capacitive sensors developed at Sandia National Laboratories. The use of ASIC technology greatly reduces the size of the electronics required to support the selected sensor types allowing deployment of many small sensor nodes over a large area of the manipulator surface to provide maximum sensor coverage. The ASIC design also provides a communication interface to support sensor commands from and sensor data transmission to a distributed processing system which allows modular implementation and operation of the sensor system. MSI is a commercial small business specializing in proximity sensing systems based upon infrared and acoustic sensors.

    Participation in extreme sports has been linked to personal transformations in everyday life. Descriptions of lived experience resulting from transformative experiences are limited. Proximity flying, a relatively new discipline involving BASE jumping with a wingsuit where participants fly close to solid structures, is arguably one of the most extreme of extreme sports. The aim of this paper, part of a larger phenomenological study on the lived experience of proximity flying, is to explicate the ways in which participating in proximity flying influences the everyday lives of participants. Interpretative phenomenological analysis was used to explicate the lived experience of six proximity pilots. An analysis of interview transcripts revealed three significant themes describing the lived experience of participants. First, experiences of change were described as positive and skills developed through proximity flying were transferable into everyday life. Second, transformative experiences were considered fundamental to participants’ perspectives on life. Third, experience of transformation influenced their sense of personal identity and facilitated flourishing in other aspects of everyday life. Participants were clear that their experiences in proximity flying facilitated a profound process of transformation which manifest as changes in everyday capabilities and behaviors, values and sense of identity.

    Full Text Available En 1998 el inicio de la temporada de actividad de un balneario en Gipuzkoa coincidió con la detección de un brote de legionelosis asociado al mismo, lo cual condujo al cierre de la instalación y al estudio epidemiológico -casos y controles- y ambiental oportunos. Se definió como caso toda persona que durante su estancia en el balneario o durante los 10 días siguientes presentará neumonía o un cuadro febril compatible con fiebre de Pontiac.El estudio ambiental incluyó la inspección del balneario y entorno y muestreos de los sistemas sanitarios de agua y de los elementos de hidroterapia.De las 287 personas encuestadas de la Comunidad Autónoma Vasca, el 12.5% cumplían con la definición de caso; 9 casos presentaron neumonía y 26 fiebre de Pontiac. La curva epidémica se inició el 7 de mayo, alcanzando un pico los días 14 y 15 de mayo y finalizando el día 20. El riesgo de enfermar ajustado por edad, sexo y consumo de tabaco se asoció con la duración de la estancia en el balneario (OR=118.5, 95% I.C: 18.7-750.2 y con el uso de una piscina (OR=10.5, 95% I.C: 1.3-82.6.

    Asthma is a chronic inflammatory lung disease that leads to 250 000 deaths annually. There is a need to better understand asthma by identifying new pathogenic molecules. We conducted a liquid-chromatography time-of-flight mass spectrometry (LC-Q-TOF-MS)-based metabolomics study to test for asthma and investigate the interventional mechanisms of surfactant protein A (SPA) in OVA-induced asthma mice. The results revealed that asthma disturbed 32 metabolites in 9 metabolic pathways. After SPA treatment, the metabolomics profile found in asthma was significantly reversed, shifting much closer to that of the control group, indicating that SPA has therapeutic effects against asthma. Metabolomic pathway analysis by the ingenuity pathway analysis demonstrated that several pathways including fatty acid metabolism, lipid metabolism, and purine metabolism were significantly altered in asthma. This study offers new methodologies for the understanding of asthma and the mechanisms of SPA in treating asthma.

    The purpose of this study was to evaluate the effectiveness and complications of the locking proximal humerus plate to treat proximal humerus fractures. A retrospective clinical trial. Department of Orthopaedics, Tianjin Medical University General Hospital. Sixty-eight consecutive patients with three- or four-part fractures of the proximal humerus were treated with locking proximal humerus plates. The deltopectoral anterolateral acromial approach was used to the proximal humerus; open reduction and locking proximal humerus plate were applied. Constant Score was used to measure the shoulder functional recovery, and Visual Analog Scale (VAS) was used to measure subjective evaluation of pain. The radiology was observed. After average 26.7 months, the average Constant Score was 72.6 ± 13.2 points and the average VAS was 1.2 ± 0.8 points. All the complications such as screw perforation into the glenohumeral joint, screws loosening, soft tissue infections, avascular necrosis and delayed union occurred in eight cases (11.8 %). The effectiveness of the locking proximal humerus plate was similar to other published literatures on treating fractures of the proximal humerus; however, a lower complications rate in short follow-up time was observed in this study. It may potentially provide a favorable option for treating three- or four-part fractures of the proximal humerus. Dealing with each particular fracture pattern, surgeons should have a decision of appropriate way to internal fixation.

  15. 'An adept in medicine': the Reverend Dr William Laing, nervous complaints and the commodification of spa water.

    Science.gov (United States)

    Eddy, M D

    2008-03-01

    This essay addresses mineral water as a medical, experimental and economic material. It focuses on the career of the Reverend Dr William Laing (1742-1812), a physician and cleric who wrote two pamphlets about the water of provincial spa located in Peterhead, a town on the north-east coast of Scotland. I begin by outlining his education and I then reconstruct the medical theory that guided his efforts to identify tonics in the well's water. Next, I explain why Laing and several other local inhabitants thought themselves to be authorities on the palliative power of the water and I close by showing how such effects were commodified by local entrepreneurs. Although I concentrate primarily upon Peterhead Spa, this study touches upon several issues relevant to the types of medical theory and chemical experimentation that were being used in provincial Scotland during the late eighteenth and early nineteenth centuries.

    The DNA assisted solid-phase proximity ligation assay (SP-PLA) provides a unique opportunity to specifically detect prion protein (PrP) aggregates by investigating the collocation of 3 or more copies of the specific protein. We have developed an SP-PLA that can detect PrP aggregates in brain homogenates from infected hamsters even after a 10(7)-fold dilution. In contrast, brain homogenate from uninfected animals did not generate a detectable signal at 100-fold higher concentration. Using either of the 2 monoclonal anti-PrP antibodies, 3F4 and 6H4, we successfully detected low concentrations of aggregated PrP. The presented results provide a proof of concept that this method might be an interesting tool in the development of diagnostic approaches of prion diseases.

    The prevalence of meticillin-resistant Staphylococcus aureus (MRSA) in Norway is low but increasing. Over the last decade, numerous nursing homes have experienced MRSA outbreaks. One genetic lineage, spa type t304, has been identified at multiple nursing homes and has caused large outbreaks lasting for several years. To evaluate whether spa typing is sufficient for the detection of MRSA spread and endemic establishment in a low-prevalence area, using spa type t304 as the test organism. All spa type t304 isolates detected in 1991-2010 in the most densely populated area of Norway were included. Time and place of bacterial sampling were recorded. The isolates were analysed using multi-locus sequence typing, staphylococcal cassette chromosome mec typing, detection of lukS/F-PV and pulsed-field gel electrophoresis (PFGE). In total, 181 spa type t304 isolates were identified in three of 23 municipalities. Most (91%) of the isolates could be linked to 13 nursing homes, eight of which experienced outbreaks. PFGE analysis revealed three PFGE types, consisting of 19 PFGE patterns; 95% of the isolates were PFGE type 2. In total, PFGE types 2 and 3 accounted for 99% of all nursing home isolates, and included isolates from different nursing homes, different outbreaks and different time periods. Additional genetic analyses did not further differentiate between the spa type t304 isolates. MRSA spa type t304 appears to have established itself as an endemic genetic lineage in the study area. spa typing does not provide sufficient resolution when investigating the spread of an endemic-like genetic lineage in a low-prevalence area, and should be supplemented by additional typing techniques.

    Degenerative joints and disc disease is accompanied by chronic pain which is the main symptom of the disease. Medical spa therapy has the task of providing comprehensive treatment embracing diseases of limbs as well as other systems and the essential role of medical treatment, in particular spa therapy, is pain relief. The aim of the study was to evaluate the effect of the spa treatment on the level of pain perception in patients with degenerative joints and disc disease. The observation embraced 120 people with degenerative joints and disc disease treated in the spa. The study included a comprehensive therapy conducted over a 21-day stays at the spa Przerzeczyn-Zdrój with the application of selected physical treatments, physiotherapy and the use of therapeutic natural resources: peloid mud and healing radon-sulphide water. Moreover, there was psychological counseling and health education conducted. The study also included observation of 21 persons from the control group. However, the patients in the control group did not benefit from balneotherapy, psychological care and education. There was a standard VAS scale for pain and non-standard questionnaire of pain assessment constructed for the study purposes. The assessment of pain using the VAS scale and questionnaire of pain assessment both in the study group and the control group were performed before and after the treatment. The results were analyzed statistically, there was Statistica program in Polish version used. In the analysis of the obtained results there were two tests scheduled: the sign test, the Wilcoxon test and descriptive statistics. As a result of the spa therapy and treatments administered on an outpatient basis there was reduction of pain intensity observed. 1. Spa therapy and outpatient treatment reduce the level of pain in patients with degenerative joints and disc disease. 2. The reduction of pain level was more effective in case of therapy conducted in the spa.

    Background: Staphylococcus aureus, a leading cause of community-acquired and nosocomial infections, remains a major health problem worldwide. Molecular typing methods, such as spa typing, are vital for the control and, when typing can be made more timely, prevention of S. aureus spread around healthcare settings. The current study aims to review the literature to report the most common clinical spa types around the world, which is important for epidemiological surveys and nosocomial infection control policies. Methods: A search via PubMed, Google Scholar, Web of Science, Embase, the Cochrane library, and Scopus was conducted for original articles reporting the most prevalent spa types among S. aureus isolates. The search terms were “Staphylococcus aureus, spa typing.” Results: The most prevalent spa types were t032, t008 and t002 in Europe; t037 and t002 in Asia; t008, t002, and t242 in America; t037, t084, and t064 in Africa; and t020 in Australia. In Europe, all the isolates related to spa type t032 were MRSA. In addition, spa type t037 in Africa and t037and t437 in Australia also consisted exclusively of MRSA isolates. Given the fact that more than 95% of the papers we studied originated in the past decade there was no option to study the dynamics of regional clone emergence. Conclusion: This review documents the presence of the most prevalent spa types in countries, continents and worldwide and shows big local differences in clonal distribution. PMID:29487578

  5. The Present and Future of Szigetvár Spa – An Economic Analysis of Geothermal Energy Investment

    2014-09-01

    Full Text Available In Hungary, geothermal energy has proved to be an economical source of energy for direct use. It highlights the pros and cons of including renewable energy in the power generation mix of Hungary, and the pros and cons of local application. This paper looks at the operation of Szigetvár Spa from both economic and social aspects. In this study, qualitative analysis is used for the basic economic and social introduction of the Spa, and then real options, based on quantitative methods, are described to identify the long-term financial consequences of the project. In 1966, thermal water was found in Szigetvár. In 1997, this thermal water was certified as medicinal water. The wellhead temperature of Szigetvár thermal water is 62°C in the 790 metres deep thermal well. It is used as so-called domestic hot water in the Szent István housing estate and in Szigetvár Spa. One of the problems with the project is that it is based on single stage thermal water utilization, another problem is that the waste water is too hot. This can be solved by exploiting the heat energy of thermal water more intensively. This way, maximum benefits can be gained from geothermal energy with minimum use of energy. Static and dynamic investment analyses were carried out to examine the spa from a financial aspect. The methods used include static payback period, average rate of return, levelized cost of electricity, net present value, profitability index, dynamic payback period, internal rate of return and real options. By pricing geothermal technology, it is possible to identify the strategic value of flexibility, to quantify what was previously left unquantified, and thus to show that geothermal investments are profitable not only from a social but also from a financial aspect as well.

    Atmospheric observations from tall towers are an important source of information about CO2 exchange at the regional scale. Here, we have used a forward running model, WRF-SPA, to generate a time series of CO2 at a tall tower for comparison with observations from Scotland over multiple years (2006-2008). We use this comparison to infer strength and distribution of sources and sinks of carbon and ecosystem process information at the seasonal scale. The specific aim of this research is to combine a high resolution (6 km) forward running meteorological model (WRF) with a modified version of a mechanistic ecosystem model (SPA). SPA provides surface fluxes calculated from coupled energy, hydrological and carbon cycles. This closely coupled representation of the biosphere provides realistic surface exchanges to drive mixing within the planetary boundary layer. The combined model is used to investigate the sources and sinks of CO2 and to explore which land surfaces contribute to a time series of hourly observations of atmospheric CO2 at a tall tower, Angus, Scotland. In addition to comparing the modelled CO2 time series to observations, modelled ecosystem specific (i.e. forest, cropland, grassland) CO2 tracers (e.g., assimilation and respiration) have been compared to the modelled land surface assimilation to investigate how representative tall tower observations are of land surface processes. WRF-SPA modelled CO2 time series compares well to observations (R2 = 0.67, rmse = 3.4 ppm, bias = 0.58 ppm). Through comparison of model-observation residuals, we have found evidence that non-cropped components of agricultural land (e.g., hedgerows and forest patches) likely contribute a significant and observable impact on regional carbon balance.

    Thus far, all solved structures of pilin-proteins comprising sortase-assembled pili are from pathogenic genera and species. Here, we present the first crystal structure of a pilin subunit (SpaA) from a non-pathogen host (Lactobacillus rhamnosus GG). SpaA consists of two tandem CnaB-type domains, each with an isopeptide bond and E-box motif. Intriguingly, while the isopeptide bond in the N-terminal domain forms between lysine and asparagine, the one in the C-terminal domain atypically involves aspartate. We also solved crystal structures of mutant proteins where residues implicated in forming isopeptide bonds were replaced. Expectedly, the E-box-substituted E139A mutant lacks an isopeptide bond in the N-terminal domain. However, the C-terminal E269A substitution gave two structures; one of both domains with their isopeptide bonds present, and another of only the N-terminal domain, but with an unformed isopeptide bond and significant conformational changes. This latter crystal structure has never been observed for any other Gram-positive pilin. Notably, the C-terminal isopeptide bond still forms in D295N-substituted SpaA, irrespective of E269 being present or absent. Although E-box mutations affect SpaA proteolytic and thermal stability, a cumulative effect perturbing normal pilus polymerization was unobserved. A model showing the polymerized arrangement of SpaA within the SpaCBA pilus is proposed. PMID:27349405

    SpaE is the predicted basal pilin subunit in the sortase-dependent SpaFED pilus from the gut-adapted and commensal Lactobacillus rhamnosus GG. Thus far, structural characterization of the cell-wall-anchoring basal pilins has remained difficult and has been limited to only a few examples from pathogenic genera and species. To gain a further structural understanding of the molecular mechanisms that are involved in the anchoring and assembly of sortase-dependent pili in less harmful bacteria, L. rhamnosus GG SpaE for crystallization was produced by recombinant expression in Escherichia coli. Although several attempts to crystallize the SpaE protein were unsuccessful, trigonal crystals that diffracted to a resolution of 3.1 Å were eventually produced using PEG 3350 as a precipitant and high protein concentrations. Further optimization with a combination of additives led to the generation of SpaE crystals in an orthorhombic form that diffracted to a higher resolution of 1.5 Å. To expedite structure determination by SAD phasing, selenium-substituted (orthorhombic) SpaE crystals were grown and X-ray diffraction data were collected to 1.8 Å resolution.

    Methicillin-resistant Staphylococcus aureus (MRSA) represent a serious threat for public health worldwide. Of particular concern is the emergence of community-acquired MRSA, which is often difficult to distinguish from nosocomial MRSA due to a lack of suitable typing methods for early detection. For example, the USA300 pulsed-field gel electrophoresis (PFGE) pattern includes both the 'classical' community-acquired USA300 clone with spa type t008 and an epidemiologically unrelated nosocomial clone with spa type t024. Likewise, spa typing cannot distinguish the classic USA300 from nosocomial MRSA with the spa type t008. Since the fast and high-resolution distinction of these S. aureus types is important for infection prevention and surveillance, we investigated whether multiple-locus variable number tandem repeat fingerprinting (MLVF) can be applied to overcome these limitations. Indeed, MLVF correctly grouped 91 MRSA isolates belonging to the classic USA300 lineage, nosocomial MRSA isolates with the USA300 PFGE profile and spa type t024, and nosocomial MRSA isolates with spa type t008 into 3 distinct clusters. Importantly, several sub-clusters were also identified, reflecting epidemiological relationships between the respective isolates. We conclude that MLVF has the discriminatory power needed to rapidly distinguish very similar community-acquired and nosocomial MRSA isolates and that MLVF-based sub-clustering of isolates is highly useful for epidemiological investigations, outbreak prevention, and control.

    A number of molecular typing methods have been developed for characterization of Staphylococcus aureus isolates. The utility of these systems depends on the nature of the investigation for which they are used. We compared two commonly used methods of molecular typing, multilocus sequence typing (MLST) (and its clustering algorithm, Based Upon Related Sequence Type [BURST]) with the staphylococcal protein A (spa) typing (and its clustering algorithm, Based Upon Repeat Pattern [BURP]), to assess the utility of these methods for macroepidemiology and evolutionary studies of S. aureus in the United States. We typed a total of 366 clinical isolates of S. aureus by these methods and evaluated indices of diversity and concordance values. Our results show that, when combined with the BURP clustering algorithm to delineate clonal lineages, spa typing produces results that are highly comparable with those produced by MLST/BURST. Therefore, spa typing is appropriate for use in macroepidemiology and evolutionary studies and, given its lower implementation cost, this method appears to be more efficient. The findings are robust and are consistent across different settings, patient ages, and specimen sources. Our results also support a model in which the methicillin-resistant S. aureus (MRSA) population in the United States comprises two major lineages (USA300 and USA100), which each consist of closely related variants.

    Full Text Available Tourism potential of the tourist destination is determined using the evaluation of natural and anthropogenic resources which are significant for the development of certain forms of tourism. Specifically, for the evaluation of tourist potential Spa of Niš, a tourist and geographical location and a concrete zone size can be used, as well as the attractiveness of natural and anthropogenic resources, facilities already built of infra and supra structures and so on. According to the recommendation of the World Tourism Organization (UNWTO for precise inventory and assessment of tourist values, it is desirable to outline a standard form by which the researchers could perform an inventory of tourist potential of a particular spatial area, regardless of size or hierarchical rang. In this paper, in a universal way, through analysis and synthesis of the values of internal and external factors, an attempt has been made to determine the value of the tourism potential Spa of Niš. In addition, a scoring method is used, by which it is possible to examine and compare a number of properties of various tourism resources. Lack of the scoring method can be seen through subjectivity which prevails in all stages of evaluation, but if adequately implemented, it still can give satisfactory results. The main aim of the research to rank the valorization of tourism potential, identify the advantages and disadvantages Spa of Niš tourism, as compared to other tourist destination of health and wellness tourism in Serbia, and in the wider environment, as well.

    Full Text Available Objectives: The present study was aimed at evaluating microbiological contamination of air in Ciechocinek and Ino­wro­cław – Polish lowland spa towns. Additionally, the impact of open-air inhalatoria on the quality of air was evaluated. Material and Methods: Air samples were collected seasonally in the urban areas, in the recreation areas and in the vicinity of inhalatoria in both towns using impaction. The numbers of mesophilic bacteria, staphylococci, hemolytic bacteria and actinomycetes were determined on media according to the Polish Standard PN-86/Z-04111/02. The number of moulds was determined on media according to the Polish Standard PN-86/Z-04111/03. Results: While the highest numbers of microorganisms were noted at the sites located in the urban areas, the lowest numbers were noted in the vicinity of the open-air inhalatoria. In all the investigated air samples the values of bioaerosol concentrations were below the recommended TLVs (≤ 5000 CFU×m–3 for both bacteria and fungi in outdoor environments. Location of the sampling site was invariably a decisive factor in determining the number of microorganisms in the air. Conclusions: The aerosol which is formed in the open-air inhalatoria has a positive influence on microbiological air quality. Owing to a unique microclimate and low air contamination, Ciechocinek and Inowrocław comply with all necessary requirements set for health resorts specializing in treating upper respiratory tract infections.

    The aim of this study was optimizing conditions for the specific activities determination of some uranium-series radionuclides present in Spa rus aura ta by alpha spectrometry. Determinations of specific activities were conducted varying the type of digestion: acid attack on hot plate, controlled microwave digestion and acid attack after calcination of the sample. The latter procedure was applied only to the case of uranium isotopes determination. The variation in the isotope extraction method consisted of applying the techniques of liquid-liquid extracting using Tributyl phosphate or chromatographic UTEVA resin. Results depending on the type of treatment given to the samples were compared based on obtained chemical yields. The results reveal a higher bioaccumulation of polonium in the liver sample, with activities of 0.809, 2.495 and 2.439 Bq kg{sup -1} fresh wt compared with the fillet. The best chemical yields of polonium were close to 60% for samples that were digested by microwave. In the case of uranium the best chemical yields, close to 80% for fillet, were obtained with a previous calcination of the sample and using the UTEVA resin. (Author)

  18. Locking plate fixation for proximal humerus fractures.

    Burke, Neil G

    2012-02-01

    Locking plates are increasingly used to surgically treat proximal humerus fractures. Knowledge of the bone quality of the proximal humerus is important. Studies have shown the medial and dorsal aspects of the proximal humeral head to have the highest bone strength, and this should be exploited by fixation techniques, particularly in elderly patients with osteoporosis. The goals of surgery for proximal humeral fractures should involve minimal soft tissue dissection and achieve anatomic reduction of the head complex with sufficient stability to allow for early shoulder mobilization. This article reviews various treatment options, in particular locking plate fixation. Locking plate fixation is associated with a high complication rate, such as avascular necrosis (7.9%), screw cutout (11.6%), and revision surgery (13.7%). These complications are frequently due to the varus deformation of the humeral head. Strategic screw placement in the humeral head would minimize the possibility of loss of fracture reduction and potential hardware complications. Locking plate fixation is a good surgical option for the management of proximal humerus fractures. Complications can be avoided by using better bone stock and by careful screw placement in the humeral head.

    Diabetes mellitus is not just a simple metabolic disorder, however, it is considered to be a cardiovascular disease of a metabolic origin. This is apparent especially when speaking about type 2 diabetes (DM II). The objective of our study was to determine whether a comprehensive spa treatment (procedures and drinking cure) may affect the level of the sympathetic tone of patients suffering from DM II. As an indicator of the sympathetic tone, selected electrocardiographic parameters derived from the heart rate variability and microwave alternans were chosen. There were 96 patients enrolled in our study: 38 patients with poorly controlled DM II and two control groups: 9 patients with compensated DM II and 49 patients, average age without diabetes or other disorders of the glucose metabolism. All received an identical spa treatment and continued their medical therapy. The electrophysiological examination of patients was performed before and after a three-week spa treatment using the KARDiVAR system. Parameters derived from the analysis of heart rate variability (HRV), microvolt T-wave alternans, and microvolt R-wave alternans were analyzed in order to evaluate the tones of the autonomic nervous system (ANS). The control group showed a slight increase of parameter the index of activity of regulatory systems (IRSA) (4.4+/-1.3 vs. 3.8+/-1.4; p=0.006) after the spa treatment, while increased heart rate (80.9+/-11.0 vs. 74.6+/-9.6; p=0.028), reduced index of centralization (IC) (1.3+/-0.6 vs. 2.9+/-1.4; p=0.027) and reduced index of myocardium (IM) (9.9+/-7.4 vs. 18.0+/-6.3; p=0.041) were found in patients with a compensated DM II. Patients with a poorly compensated DM II showed a decreased IM (10.9+/-8.6 vs. 16.9+/-5.2; p=0.001) and also a reduced IRSA (4.1+/-3.5 vs. 6.3+/-1.9; p=0.001). The results proved favorable changes in ANS cardiovascular control of patients with DM II after a spa treatment, especially in terms of reducing the sympathoadrenal system activity

    Streptococcus mutans and Streptococcus sobrinus are the main pathogens associated with the development of dental caries in humans. Recently, the real-time polymerase chain reaction (qPCR-TR) has been used for fast and exact quantification of these bacteria species. This molecular biology method has made the detection of these bacteria in saliva and dental plaque possible; additionally, it aids the development of illness risk prediction. The purpose of this prospective, analytic, transversal, observational and unicenter study was to quantify the spaP gene of the Streptococcus mutans and its correlation with caries in a group of children using isolated DNA from plaque samples processed through qPCR-TR, using specific oligonucleotides for this gene detection. The cariogenic potential of Streptococcus mutans in the dental plaque was analysed in a group of patients aged 12 to 46 months. A descriptive statistical analysis was performed. The Spearman's correlation coefficient was used to establish the correlation between caries (dmft) index (decayed/missing/filled primary teeth), spaP gene and age group. The Wilcoxon test was used to compare MSB cultivation technique and qPCR-TR. In the molecular trials, a close association between caries prevalence in childhood and the presence and high proportion of the spaP gene of S. mutans was found. The average caries prevalence was 3.71, and it increased as age range increased. The highest caries prevalence was observed in female patients and in the oldest age range studied (40 46 months) which contrasts with the 12-18 months age that had a caries (dmft) index of zero. The amplification using as initiator the gene spaP of the nucleic acids extracted from the S. mutans resulted positive in 91.3% of the cases. Every child with caries was positive for the spaP and only 8.75% were negative, this group included children without caries. In conclusion, there was a correlation with infant caries prevalence and S. mutans.

    Angiogenesis involves the generation of new blood vessels from the existing vasculature and is dependent on many growth factors and signaling events. In vivo angiogenesis is dynamic and complex, meaning assays are commonly utilized to explore specific targets for research into this area. Tube-forming assays offer an excellent overview of the molecular processes in angiogenesis. The Matrigel tube forming assay is a simple-to-implement but powerful tool for identifying biomolecules involved in angiogenesis. A detailed experimental protocol on the implementation of the assay is described in conjunction with an in-depth review of methods that can be applied to the analysis of the tube formation. In addition, an ImageJ plug-in is presented which allows automatic quantification of tube images reducing analysis times while removing user bias and subjectivity.

    In this thesis, we present ProxiSART, a flexible proximal framework for robust 3D cone beam tomographic reconstruction based on the Simultaneous Algebraic Reconstruction Technique (SART). We derive the proximal operator for the SART algorithm and use it for minimizing the data term in a proximal algorithm. We show the flexibility of the framework by plugging in different powerful regularizers, and show its robustness in achieving better reconstruction results in the presence of noise and using fewer projections. We compare our framework to state-of-the-art methods and existing popular software tomography reconstruction packages, on both synthetic and real datasets, and show superior reconstruction quality, especially from noisy data and a small number of projections.

    Human behaviors exhibit ubiquitous correlations in many aspects, such as individual and collective levels, temporal and spatial dimensions, content, social and geographical layers. With rich Internet data of online behaviors becoming available, it attracts academic interests to explore human mobility similarity from the perspective of social network proximity. Existent analysis shows a strong correlation between online social proximity and offline mobility similarity, namely, mobile records between friends are significantly more similar than between strangers, and those between friends with common neighbors are even more similar. We argue the importance of the number and diversity of common friends, with a counter intuitive finding that the number of common friends has no positive impact on mobility similarity while the diversity plays a key role, disagreeing with previous studies. Our analysis provides a novel view for better understanding the coupling between human online and offline behaviors, and will help model and predict human behaviors based on social proximity.

    Children with ambiguous genitalia due to different chromosome or gonadal sex are a particular challenge concerning the diagnostic and therapeutic implications. Proximal hypospadias patients with normal gonadal development should be distinguished from children with DSD (disorders of sex development) to guarantee normal gender identity and the best possible surgical therapy. This paper focuses on the terminology, embryology, and pathophysiology of the different manifestations of DSD. The state of knowledge about this disease pattern with particular emphasis on proximal hypospadias based on national and international scientific discussions is presented. The different clinical pictures as well as therapeutic options of DSD with a special focus on recent literature and giving particular attention to patients with proximal hypospadias are presented. Because of the complexity of patients suffering from disorders of sex development an interdisciplinary DSD healthcare team including a paediatric endocrinologist as well as paediatric urologist should be provided. These specialists enable an accurate diagnosis in severe hypospadias patients without reference to DSD diseases patterns.

    The single-cell gel electrophoresis technique or comet assay is widely regarded as a quick and reliable method of analysing DNA damage in individual cells. It has a proven track record from the fields of biomonitoring to nutritional studies. The assay operates by subjecting cells that are fixed in agarose to high salt and detergent lysis, thus removing all the cellular content except the DNA. By relaxing the DNA in an alkaline buffer, strands containing breaks are released from supercoiling. Upon electrophoresis, these strands are pulled out into the agarose, forming a tail which, when stained with a fluorescent dye, can be analysed by fluorescence microscopy. The intensity of this tail reflects the amount of DNA damage sustained. Despite being such an established and widely used assay, there are still many aspects of the comet assay which are not fully understood. The present review looks at how the comet assay is being used, and highlights some of its limitations. The protocol itself varies among laboratories, so results from similar studies may vary. Given such discrepancies, it would be attractive to break the assay into components to generate a mathematical model to investigate specific parameters.

    Proximal radioulnar synostosis is a rare upper limb malformation. The elbow is first identifiable at 35 days (after conception), at which stage the cartilaginous anlagen of the humerus, radius and ulna are continuous. Subsequently, longitudinal segmentation produces separation of the distal radius and ulna. However, temporarily, the proximal ends are united and continue to share a common perichondrium. We investigated the hypothesis that posterior congenital dislocation of the radial head and proximal radioulnar fusion are different clinical manifestations of the same primary developmental abnormality. Records were searched for ''proximal radioulnar fusion/posterior radial head dislocation'' in patients followed at the local Children's Hospital and Rehabilitation Centre for Children. Relevant radiographic, demographic and clinical data were recorded. Ethics approval was obtained through the University Research Ethics Board. In total, 28 patients met the inclusion criteria. The majority of patients (16) had bilateral involvement; eight with posterior dislocation of the radial head only; five had posterior radial head dislocation with radioulnar fusion and two had radioulnar fusion without dislocation. One patient had bilateral proximal radioulnar fusion and posterior dislocation of the left radial head. Nine patients had only left-sided involvement, and three had only right-sided involvement.The degree of proximal fusion varied, with some patients showing 'complete' proximal fusion and others showing fusion that occurred slightly distal to the radial head: 'partially separated.' Associated disorders in our cohort included Poland syndrome (two patients), Cornelia de Lange syndrome, chromosome anomalies (including tetrasomy X) and Cenani Lenz syndactyly. The suggestion of a developmental relationship between posterior dislocation of the radial head and proximal radioulnar fusion is supported by the fact that both anomalies

    The relevance of the problem arises from the lack of substantiation for the inclusion of transcutaneous spinal direct current stimulation (tSDCS) in the comprehensive spa and health resort-based treatment of back pain syndrome in the adolescents presenting with juvenile idiopathic scoliosis. The objective of the present study was to demonstrate the effectiveness of transcutaneous spinal direct current stimulation for the comprehensive spa and health resort-based treatment of back pain syndrome in the adolescents presenting with juvenile idiopathic scoliosis. A total of 18 patients with scoliosis forming the study group 1 received the traditional comprehensive spa and health resort-based treatment. The course of transcutaneous spinal direct current stimulation was prescribed to 38 other patients (comprising group 2) in addition to the standard procedures. Another control group was comprised of 15 practically healthy adolescents having no signs of spinal deformations. The visual analog scale for pain, the McGill questionnaire, the scale for the assessment of the situational and personal uneasiness levels (Spilberger Ch.D., Khanin Yu.L.), and the Beck and Tsung depression scales were used, beside the routine clinical methods. Statistical data processing was carried out with the use of the Statistica 6.0 software package. In the group of patients treated with the use of transcutaneous spinal direct current stimulation, regression of pain syndrome was well apparent. In the boys with the severity of pain estimated at 2 points based on the visual analog scale who received the standard course of the spa and health resort-based treatment, the pain rank index and the index of the number of the selected descriptors decreased significantly but nonetheless remained higher than in the patients treated by means of tSDCS as a component of the combined therapy (p=0.039). Simultaneously, the significantly lower level of situational (Q1=25.00; Me=36.50; Q3=45.00; p=0.036) and

    Full Text Available Nowadays, inductive proximity sensor and mobile robot are one of the most interesting topics attracting scientists. With enhancement techniques from using sensor for controlling mobile robots which can be developed more in the future. Additionally, measuring of static performance of inductive proximity sensor is also essential because the testing and navigation systems perform more exactly by result information from the experiment by assaying the output signal. In this paper, the hand-made measurement system is used to verify again the static performance of proximity sensor with ferrous, non-ferrous and alloy metal tape. Simultaneously, improve static properties of typical tape metal through the relationship between the output signal and the sensing distance of sensor. According to theoretical basis, the relationship of the static parameters can be determined such as: thickness of metal, sensing distance, dimension of metal, and so on. The testing results have shown the output signal of proximity sensor in the model and theory is not similar. The final data will accommodate some information about the relationship of the thickness of metal tape and the sensing distance of proximity sensor, the different affects of position sensor and optimum operation range of mobile robot.

  13. Real-Time PCR to Identify Staphylococci and Assay for Virulence from Blood.

    The genus Staphylococcus includes pathogenic and non-pathogenic facultative anaerobes. Due to the plethora of virulence factors encoded in its genome, the species Staphylococcus aureus is known to be the most pathogenic. S. aureus strains harboring genes encoding virulence and antibiotic resistance are of public health importance. In clinical samples, however, pathogenic S. aureus is often mixed with putatively less pathogenic coagulase-negative staphylococci (CoNS), both of which can harbor mecA, the genetic driver for staphylococcal methicillin-resistance. In this chapter, the detailed practical procedure for operating a real-time pentaplex PCR assay in blood cultures is described. The pentaplex real-time PCR assay simultaneously detects markers for the presence of bacteria (16S rRNA), coagulase-negative staphylococcus (cns), S. aureus (spa), Panton-Valentine leukocidin (pvl), and methicillin resistance (mecA).

    composition of chromatin in proximity to the nuclear protein of interest. Using the RAD18 protein as a model, we demonstrated that the RAD18-proximal chromatin is enriched in some H4 acetylated species. Moreover, the RAD18-proximal chromatin containing a replacement histone H2Az has a different pattern of H4 acetylation.Conclusion. Progress in the last decade in cancer drug therapy has led us to the conclusion that the nucleus of eukaryotic cells is an active site for many cellular processes important to the development of cancer. These processes include changes in genetic and epigenetic landscape (e. g. methylation of DNA, modification of histones and the expression levels of transcription factors, which regulates gene products (e.g. hypoxia-inducible factor 1α (HIF-1α in chronic anemia, etc. where protein-protein interactions play important role. Understanding the nature of protein-protein interactions may improve design strategies for small-molecule PPI modulators. PPI assay technologies that closely reflect physiological conditions hold the key to developing specific anti-cancer drugs.

    Here, we report the extensive bioinformatic and functional analyses of the unusual pLOCK 0919, a plasmid originating from the probiotic Lactobacillus casei LOCK 0919 strain. This plasmid is atypical because it harbors the spaCBA-srtC gene cluster encoding SpaCBA pili. We show that all other spaCBA-srtC sequences of the Lactobacillus genus that have been previously described and deposited in GenBank are present in the chromosomal DNA. Another important observation for pLOCK 0919 is that the spaCBA-srtC gene cluster and its surrounding genes are highly similar to the respective DNA region that is present in the most well-known and active SpaCBA pili producer, the probiotic Lactobacillus rhamnosus GG strain. Our results demonstrate that the spaCBA-srtC clusters of pLOCK 0919 and L. rhamnosus GG are genealogically similar, located in DNA regions that are rich in transposase genes and are poorly conserved among the publicly available sequences of Lactobacillus sp. In contrast to chromosomally localized pilus gene clusters from L. casei and Lactobacillus paracasei, the plasmidic spaC of L. casei LOCK 0919 is expressed and undergoes a slight glucose-induced repression. Moreover, results of series of in vitro tests demonstrate that L. casei LOCK 0919 has an adhesion potential, which is largely determined by the presence of the pLOCK 0919 plasmid. In particular, the plasmid occurrence positively influenced the hydrophobicity and aggregation abilities of L. casei LOCK 0919. Moreover, in vivo studies indicate that among the three Lactobacillus strains used to colonize the gastrointestinal tract of germ-free mice, already after 2 days of colonization, L. casei LOCK 0919 became the dominant strain and persisted there for at least 48 days. © The Author 2015.

    Genetic variation in C-type lectins influences infectious disease susceptibility but remains poorly understood. We used allelic mRNA expression imbalance (AEI) technology for surfactant protein (SP)-A1, SP-A2, SP-D, dendritic cell-specific ICAM-3-grabbing non-integrin (DC-SIGN), macrophage mannose receptor (MRC1) and Dectin-1, expressed in human macrophages and/or lung tissues. Frequent AEI, an indicator of regulatory polymorphisms, was observed in SP-A2, SP-D and DC-SIGN. AEI was measured for SP-A2 in 38 lung tissues using four marker single-nucleotide polymorphisms (SNPs) and was confirmed by next-generation sequencing of one lung RNA sample. Genomic DNA at the SP-A2 DNA locus was sequenced by Ion Torrent technology in 16 samples. Correlation analysis of genotypes with AEI identified a haplotype block, and, specifically, the intronic SNP rs1650232 (30% minor allele frequency); the only variant consistently associated with an approximately twofold change in mRNA allelic expression. Previously shown to alter a NAGNAG splice acceptor site with likely effects on SP-A2 expression, rs1650232 generates an alternative splice variant with three additional bases at the start of exon 3. Validated as a regulatory variant, rs1650232 is in partial linkage disequilibrium with known SP-A2 marker SNPs previously associated with risk for respiratory diseases including tuberculosis. Applying functional DNA variants in clinical association studies, rather than marker SNPs, will advance our understanding of genetic susceptibility to infectious diseases.

    The anionic antimicrobial peptide SP-B(N), derived from the N-terminal saposin-like domain of the surfactant protein (SP)-B proprotein, and SP-A are lung anti-infective proteins. SP-A-deficient mice are more susceptible than wild-type mice to lung infections, and bacterial killing is enhanced in transgenic mice overexpressing SP-B(N). Despite their potential anti-infective action, in vitro studies indicate that several microorganisms are resistant to SP-A and SP-B(N). In this study, we test the hypothesis that these proteins act synergistically or cooperatively to strengthen each other's microbicidal activity. The results indicate that the proteins acted synergistically in vitro against SP-A- and SP-B(N)-resistant capsulated Klebsiella pneumoniae (serotype K2) at neutral pH. SP-A and SP-B(N) were able to interact in solution (Kd = 0.4 μM), which enabled their binding to bacteria with which SP-A or SP-B(N) alone could not interact. In vivo, we found that treatment of K. pneumoniae-infected mice with SP-A and SP-B(N) conferred more protection against K. pneumoniae infection than each protein individually. SP-A/SP-B(N)-treated infected mice showed significant reduction of bacterial burden, enhanced neutrophil recruitment, and ameliorated lung histopathology with respect to untreated infected mice. In addition, the concentrations of inflammatory mediators in lung homogenates increased early in infection in contrast with the weak inflammatory response of untreated K. pneumoniae-infected mice. Finally, we found that therapeutic treatment with SP-A and SP-B(N) 6 or 24 h after bacterial challenge conferred significant protection against K. pneumoniae infection. These studies show novel anti-infective pathways that could drive development of new strategies against pulmonary infections. Copyright © 2015 by The American Association of Immunologists, Inc.

    Tubulointerstitial fibrosis (TIF) is the hallmark of chronic kidney disease and best predictor of renal survival. Many different cell types contribute to TIF progression including tubular epithelial cells, myofibroblasts, endothelia, and inflammatory cells. Previously, most of the attention has centered on myofibroblasts given their central importance in extracellular matrix production. However, emerging data focuses on how the response of the proximal tubule, a specialized epithelial segment vulnerable to injury, plays a central role in TIF progression. Several proximal tubular responses such as de-differentiation, cell cycle changes, autophagy, and metabolic changes may be adaptive initially, but can lead to maladaptive responses that promote TIF both through autocrine and paracrine effects. This review discusses the current paradigm of TIF progression and the increasingly important role of the proximal tubule in promoting TIF both in tubulointerstitial and glomerular injuries. A better understanding and appreciation of the role of the proximal tubule in TIF has important implications for therapeutic strategies to halt chronic kidney disease progression.

    Full Text Available Osteoarthrosis (OA includes degenerative joint disorders that affect articular cartilage in the first instance, followed by changes of all components of the joint. The disease is detected in a proportion of 33% by X-ray in patients aged over 60 years. Knee OA (KOA ranks first among chronic diseases from the point of view of patient disability. This article is a review of guidelines and articles regarding arthrosis, balneotherapy, and balneotherapy in KOA treatment. These were accessed on the Pubmed site in the period March-April 2015. The components of balneo-therapy to which the selected articles refer include mud packs, mineral waters, climate change. These are evaluated in association or in comparison with other methods used in the rehabilitation specialty area for the treatment of KOA: kinesitherapy, intra-articular infiltrations, hydrothermotherapy. The changes induced by these therapies on clinical evolution (pain relief, tenderness, functionality, quality of life, depression symptoms or certain serum parameters (biomarkers of oxidative stress, inflammation and cartilage destruction, vitamin D and other serum metabolites were recorded. The results of our review are consistent with the studies focused on spa modalities in all types of OA. All these data helped defining the role of balneotherapy as part of the rehabilitation program for the treatment of KOA, through the benefits specific to it. Conclusion: Balneotherapy has beneficial effects on patients with KOA, both clinically and serologic improvements. Further studies are needed to quantify these effects using KOA specific markers, to establish a hierarchy of balneotherapy methods based on their effects on KOA, as well as to refine indications depending on the stage of the disease.

    Methicillin-resistant Staphylococcus aureus bacteria are one of the key etiological factors of hospital-acquired and community-acquired infections. MRSA strains have an ability of causing a broad spectrum infections: from a relatively mild skin infections to severe life-threatening systemic infections. They are characterized by multi-drug resistance, virulence of a number of factors, may clonally spread within the hospitals and between hospitals. The study embraced a number of 75 isolates of MRSA isolated from patients of 7 medical sites of the Gdansk region within the period of six months (June to December 2013). Strains have derived from various clinical materials, both of hospitalized patients (n=59) and outpatient (n=16). The isolates were tested for the susceptibility to antimicrobial agents accordance with the guidelines EUCAST. To estimate of the variability of occurrence of S. aureus clones used were standard spa gene, consisting in the amplified polymorphic region of the X gene encoding the protein A gene (spa). After receiving the results, a spa types were identified using international database Ridom Spa Server (www.spaserver.ridom.de). To determine the polymorphism cassette carrying the inecA gene from MRSA strains, used typing five major chromosomal cassette SCCmec (I-V) by multiplex PCR. MRSA population genetic analysis carried out on the basis of typing SCCmec cassettes and spa gene has showed a predominance of strains with SCCmec type II casette (46.7%) and SCCmec IV casette (38.7%). Less frequently detected were strains containing SCCmec I cassette (12.0%) and SCCmec III cassette (2.6%). Spa typing revealed the presence of 13 gene types in MRSA. The most frequently observed spa types were: t151 (24.0%), t003 (16.0%) in strains of the SCCmec II cassette and t437 (16.0%) and t008 (14.8%) in the isolates with SCCmec cassette IV, whereas staphylococcus with the type of spa t011 (12.0%) had SCCmec cassette I. In our population most frequent strains

    Bacterial contact in utero modulates fetal and neonatal immune responses. Maternal probiotic supplementation reduces the risk of immune-mediated disease in the infant. We investigated the immunomodulatory properties of live Lactobacillus rhamnosus GG and its SpaC pilus adhesin in human fetal intestinal models. Tumor necrosis factor (TNF)-α mRNA expression was measured by qPCR in a human fetal intestinal organ culture model exposed to live L. rhamnosus GG and proinflammatory stimuli. Binding of recombinant SpaC pilus protein to intestinal epithelial cells (IECs) was assessed in human fetal intestinal organ culture and the human fetal intestinal epithelial cell line H4 by immunohistochemistry and immunofluorescence, respectively. TLR-related gene expression in fetal ileal organ culture after exposure to recombinant SpaC was assessed by qPCR. Live L. rhamnosus GG significantly attenuates pathogen-induced TNF-α mRNA expression in the human fetal gut. Recombinant SpaC protein was found to adhere to the fetal gut and to modulate varying levels of TLR-related gene expression. The human fetal gut is responsive to luminal microbes. L. rhamnosus GG significantly attenuates fetal intestinal inflammatory responses to pathogenic bacteria. The L. rhamnosus GG pilus adhesin SpaC binds to immature human IECs and directly modulates IEC innate immune gene expression.

    The E3 ligase CONSTITUTIVELY PHOTOMORPHOGENIC 1 (COP1) has been known to mediate key signaling factors for degradation via the ubiquitin/26S proteasome pathway in both plants and animals. Here, we report a noncanonical function of Arabidopsis COP1, the central repressor of photomorphogenesis, in the form of a COP1/ SUPPRESSOR of phyA-105 (SPA) complex. We show that the COP1/SPA complex associates with and stabilizes PHYTOCHROME INTERACTING FACTOR 3 (PIF3) to repress photomorphogenesis in the dark. We identify the GSK3-like kinase BRASSINOSTEROID-INSENSITIVE 2 (BIN2) as a kinase of PIF3, which induces PIF3 degradation via 26S proteasome during skotomorphogenesis. Mutations on two typical BIN2 phosphorylation motifs of PIF3 lead to a strong stabilization of the protein in the dark. We further show that the COP1/SPA complex promotes PIF3 stability by repressing BIN2 activity. Intriguingly, without affecting BIN2 expression, the COP1/SPA complex modulates BIN2 activity through interfering with BIN2-PIF3 interaction, thereby inhibiting BIN2-mediated PIF3 phosphorylation and degradation. Taken together, our results suggest another paradigm for COP1/SPA complex action in the precise control of skotomorphogenesis.

    The 'Elguea' spa, located in the north coast of the county of Villa Clara, Cuba, is considered one of those more important spas of Latin America. The waters of this spa are rich in salts of chlorine, sodium, bromine, sulfides and its contain radon. As a result of measurements of environmental gamma dose rates carried out in the area of the spa, its were considered levels of dose between 0.13 and 2.3 mSv. The obtained results motivated that it was carried out a characterization, from the radiological point of view, of the spa. This characterization is of supreme importance to be able to evaluate the impact that it has and the discharges of its waters on the environment, as well as, those dose that the population potentially affected can receive by these discharges. With this end its were carried out quantitative determinations of those existent natural more significant radionuclides in different environmental objects coming from the area of the spa and its surroundings, as well as one characterization gamma 'in situ' of the same one. The obtained results are present in this work. (Author)

    The incidence of nosocomial Staphylococcus aureus infection is increasing annually and becoming a true global challenge. The pattern of Staphylococcus aureus protein A (spa) types in different geographic regions is diverse. This study determined the prevalence of methicillin-resistant S. aureus and different spa types in S. aureus clinical isolates. During a six-month period, 90 S. aureus isolates were recovered from 320 clinical specimens. The in vitro susceptibility of various S. aureus isolates to 16 antibiotic discs was assessed using the Kirby-Bauer disk diffusion method. Molecular typing was carried out with S. aureus protein A typing via polymerase chain reaction. The frequency of methicillin-resistant S. aureus in our study was 88.9%. Twenty-three (25.5%) isolates were positive for panton-valentine leukocidin encoding genes. S. aureus presented a high resistance rate to ampicillin (100%) and penicillin (100%). No resistance was observed to vancomycin, teicoplanin, or linezolid. The rates of resistance to the majority of antibiotics tested varied between 23.3% and 82.2%. The rate of multidrug resistance among these clinical isolates was 93.3%. The 90 S. aureus isolates were classified into five S. aureus protein A types: t037 (33.3%), t030 (22.2%), t790 (16.7%), t969 (11.1%), and t044 (7.7%). Eight (8.9%) isolates were not typable using the S. aureus protein A typing method. We report a high methicillin-resistant S. aureus rate in our hospital. Additionally, t030 and t037 were the predominant spa-types among hospital-associated S. aureus. Our findings emphasize the need for continuous surveillance to prevent the dissemination of multidrug resistance among different S. aureus protein A types in Iran.

    Hemodynamic forces play an important role in the non-uniform distribution of atherosclerotic lesions. Endothelial cells are exposed simultaneously to fluid wall shear stress (WSS) and solid circumferential stress (CS). Due to variations in impedance (global factors) and geometric complexities (local factors) in the arterial circulation a time lag arises between these two forces that can be characterized by the temporal phase angle between CS and WSS (stress phase angle–SPA). Asynchronous flows (SPA close to -180°) that are most prominent in coronary arteries have been associated with localization of atherosclerosis. Reversing oscillatory flows characterized by an oscillatory shear index (OSI) that is great than zero are also associated with atherosclerosis localization. In this study we examined the relationship between asynchronous flows and reversing flows in altering the expression of 37 genes relevant to atherosclerosis development. In the case of reversing oscillatory flow, we observed that the asynchronous condition upregulated 8 genes compared to synchronous hemodynamics, most of them proatherogenic. Upregulation of the pro-inflammatory transcription factor NFκB p65 was confirmed by western blot, and nuclear translocation of NFκB p65 was confirmed by immunofluorescence staining. A comparative study between non-reversing flow and reversing flow found that in the case of synchronous hemodynamics, reversing flow altered the expression of 11 genes, while in the case of asynchronous hemodynamics, reversing flow altered the expression of 17 genes. Reversing flow significantly upregulated protein expression of NFκB p65 for both synchronous and asynchronous conditions. Nuclear translocation of NFκB p65 was confirmed for synchronous and asynchronous conditions in the presence of flow reversal. These data suggest that asynchronous hemodynamics and reversing flow can elicit proatherogenic responses in endothelial cells compared to synchronous hemodynamics

    The professional, scientific and didactic careers of Alfred Marcin Sokołowski (1849-1924) and Władysław Matlakowski (1851-1895) are presented at the beginning. Sokołowski was an assistant and afterwards a deputy of the head of hospital department Herman Brehmer in health resort in Goerbersdorf. In 1880 Sokołowski organized the internal diseases ward and rhinolaryngological outpatient clinic at St. Spirit Hospital in Warsaw. Sokołowski published "Clinical lectures of diseases of respiratory tract" (1902-1906) and many scientific papers. He was a pioneer of Polish pulmonology, rhinolaryngology and spa treatment of respiratory tract diseases. He was a well-known social worker. Matlakowski, who was a surgeon of Surgical Clinic of Warsaw Emperor University and an assistant of Julian Kosiński specialized in abdominal surgery and gynaecologic surgery. While suffering from pulmonary tuberculosis he moved to Zakopane, where he became famous as an ethnographer, an author of two books: "Country architecture of the Tatra Highlands" and "Decoration and equipment of Polish people of the Tatra Highlands". He translated Shakespearian "Hamlet" into Polish. He was also a well-known philosopher and an ornithologist. The meeting of Sokołowski and Matlakowski in Goerbersdorf, and also their further acquaintance and friendship are described widely by the author. Their work at "Gazeta Lekarska" ("Medical Magazine's") editorial office, which was well-known in three sectors of partitioned Poland is presented with more details by the author. Finally the epitome of spa treatment of pulmonary tuberculosis is presented. Sokołowski and Matlakowski were propagators of spa treatment of pulmonary tuberculosis; Sokołowski made Goerbersdorf famous, Matlakowski did the same for Zakopane.

    The feasibility of Fourier transform near infrared (FT-NIR) spectroscopy with spectral range between 833 and 2 500 nm to detect the moldy corn kernels with different levels of mildew was verified in this paper. Firstly, to avoid the influence of noise, moving average smoothing was used for spectral data preprocessing after four common pretreatment methods were compared. Then to improve the prediction performance of the model, SPXY (sample set partitioning based on joint x-y distance) was selected and used for sample set partition. Furthermore, in order to reduce the dimensions of the original spectral data, successive projection algorithm (SPA) was adopted and ultimately 7 characteristic wavelengths were extracted, the characteristic wave-lengths were 833, 927, 1 208, 1 337, 1 454, 1 861, 2 280 nm. The experimental results showed when the spectrum data of the 7 characteristic wavelengths were taken as the input of SVM, the radial basic function (RBF) used as the kernel function, and kernel parameter C = 7 760 469, γ = 0.017 003, the classification accuracies of the established SVM model were 97.78% and 93.33% for the training and testing sets respectively. In addition, the independent validation set was selected in the same standard, and used to verify the model. At last, the classification accuracy of 91.11% for the independent validation set was achieved. The result indicated that it is feasible to identify and classify different degree of moldy corn grain kernels using SPA and SVM, and characteristic wavelengths selected by SPA in this paper also lay a foundation for the online NIR detection of mildew corn kernels.

    The aim of this study was to provide molecular characterization of methicillin-resistant Staphylococcus aureus (MRSA) spa type t127, sequence type (ST) 1 isolates, detected in a European baseline survey in holdings of breeding pigs, to determine phenotypic and genotypic drug resistance and to compare the results with those obtained from a collection of t127, ST1 MRSA and methicillin-susceptible S. aureus (MSSA) clinical isolates. Twenty-four t127, ST1 MRSA from dust sampled in different breeding holdings in Italy, Spain and Cyprus were studied, along with 2 t127, ST1 MRSA from fattening pigs and 11 human t127, ST1 MRSA and MSSA. Genotyping was performed using multilocus sequence typing (MLST), spa typing and PFGE. SCCmec elements were characterized by multiplex-PCR and resistance and pathogenicity genes by PCR and microarray. PFGE patterns separated a porcine cluster (PC) from a human cluster (HC), with 75% similarity. The PC carried SCCmec cassette type V, while all isolates of the HC carried SCCmec cassette type IVa. Kanamycin resistance mediated by aadD, fluoroquinolone and erm(A)-mediated macrolide resistance and the absence of the sakA gene were features of the PC only. All isolates of both clusters were positive for LukE-LukD and LuF-LukS-HlgA leukotoxin genes and one human MSSA harboured Panton-Valentine leucocidin genes. Despite differences in the host-specific genetic features, the possibility of PC transmission to humans cannot be excluded. MRSA spa type t127, ST1 from pigs possesses several virulence and resistance genes towards major classes of antimicrobials and may represent a serious therapeutic challenge in case of invasive infections in humans.

    Surgical management of proximal humerus fractures remains controversial and there is an increasing interest in intramedullary nailing. Created to improve previous designs, the T2-proximal humeral nail (PHN) (Stryker) has been recently released, and the English literature lacks a series evaluating its results. We present a clinical prospective study evaluating this implant for proximal humeral fractures. We evaluated the functional and radiological results and possible complications. Twenty-nine patients with displaced fractures of the proximal humerus were treated with this nail. One patient was lost right after surgery and excluded from the assessment. Eighteen patients were older than 70 years. There were 21 fractures of the proximal part of the humerus and 7 fractures that also involved the shaft; 15 of the fractures were two-part fractures (surgical neck), 5 were three-part fractures, and 1 was a four-part fracture. All fractures healed in a mean period of 2.7 months. There was one delayed union that healed in 4 months. One case of avascular necrosis of the humeral head was observed (a four-part fracture), but remained asymptomatic and did not require further treatment. In one case a back-out of one proximal screw was observed. A final evaluation with a minimum 1 year follow-up was performed by an independent observer; in 18 patients, the mean Constant score was 65.7 or 76.1% with the adjustment of age and gender; in 19 patients, the mean Oxford Shoulder Score was 21.7. The results obtained with the T2-PHN nail indicate that it represents a safe and reliable method in the treatment of two- and three-part fractures of the proximal humerus. The proximal fixation mechanism diminishes the rate of back-out of the screws, a frequent complication described in the literature. Better functional results were obtained from the patients younger than 70 years, but these were not statistically significant.

  16. Proximal tubular hypertrophy and enlarged glomerular and proximal tubular urinary space in obese subjects with proteinuria.

    Ana Tobar

    Full Text Available BACKGROUND: Obesity is associated with glomerular hyperfiltration, increased proximal tubular sodium reabsorption, glomerular enlargement and renal hypertrophy. A single experimental study reported an increased glomerular urinary space in obese dogs. Whether proximal tubular volume is increased in obese subjects and whether their glomerular and tubular urinary spaces are enlarged is unknown. OBJECTIVE: To determine whether proximal tubules and glomerular and tubular urinary space are enlarged in obese subjects with proteinuria and glomerular hyperfiltration. METHODS: Kidney biopsies from 11 non-diabetic obese with proteinuria and 14 non-diabetic lean patients with a creatinine clearance above 50 ml/min and with mild or no interstitial fibrosis were retrospectively analyzed using morphometric methods. The cross-sectional area of the proximal tubular epithelium and lumen, the volume of the glomerular tuft and of Bowman's space and the nuclei number per tubular profile were estimated. RESULTS: Creatinine clearance was higher in the obese than in the lean group (P=0.03. Proteinuria was similarly increased in both groups. Compared to the lean group, the obese group displayed a 104% higher glomerular tuft volume (P=0.001, a 94% higher Bowman's space volume (P=0.003, a 33% higher cross-sectional area of the proximal tubular epithelium (P=0.02 and a 54% higher cross-sectional area of the proximal tubular lumen (P=0.01. The nuclei number per proximal tubular profile was similar in both groups, suggesting that the increase in tubular volume is due to hypertrophy and not to hyperplasia. CONCLUSIONS: Obesity-related glomerular hyperfiltration is associated with proximal tubular epithelial hypertrophy and increased glomerular and tubular urinary space volume in subjects with proteinuria. The expanded glomerular and urinary space is probably a direct consequence of glomerular hyperfiltration. These effects may be involved in the pathogenesis of obesity

    The correction and optimization of the motor activity of the patients are currently the main priorities of all rehabilitative and recreational activities based at the spa and health resort facilities. The forms of such activities include walking tours and excursion trips. In other words, the excursion potential is one of the very important attributes of the recreational recourses. Under the current conditions characterized by the rapid socio-economic changes, the studies concerning the structural and functional transformation of spa and health resorts, recreational and tourist facilities acquire special importance, both from the humanitarian and economic points of view. The results of these studies may greatly contribute to the organization and the further development of rehabilitative and recreational activities based at the spa and health resort facilities, recreational and tourist centers taking into consideration their evolution. The objective of the present article is to analyze the structure and functions of the recreation and tourist centres as well as the modes of their cooperation with the spa and health resort facilities. In other words, these structures and their functions are both the object and the subject of the present study. The methodology of the study is based on the logical analysis of the development of the recreational and tourist systems in the framework of the evolutionary approach. (1) the notions of «tourist destination» and «recreation» have been substantiated; (2) the results of the studies carried out at the Institute of Physical Culture, Sports and Tourism and the Petrozavodsk State University have been used to elaborate the affiliate international Master Degree program «Project management in the tourism industry». The main emphasis in this program is placed on the necessity and methods of the improvement of recreational activities and more efficacious utilization of the climatic factors and the health resort infrastructure as

    Arthroscopy has become increasingly more established in the treatment of proximal humeral fractures. In addition to the known advantages of minimally invasive surgery fracture and implant positioning can be optimized and controlled arthroscopically and relevant intra-articular concomitant pathologies (e.g. biceps tendon complex and rotator cuff) can be diagnosed and treated. Arthroscopic techniques have proven to be advantageous in the treatment of various entities of greater tuberosity fractures, lesser tuberosity fractures (suture bridging technique) and subcapital humeral fractures (arthroscopic nailing). This article presents an overview on innovative arthroscopic modalities for treating proximal humeral fractures, describes the surgical techniques and the advantages compared to open procedures as well as initial clinical results.

    SINA, a signal generator that can be used for testing proximity fuses, is described. The circuitry of proximity fuses is presented; the output signal of the RF circuit results from a mixing of the emitted signal and received signal that is Doppler shifted in frequency by the relative motion of the fuse with respect to the reflecting target of surface. With SINA, digitized and stored target and clutter signals (previously measured) can be transformed to Doppler signals, for example during a real flight. SINA can be used for testing fuse circuitry, for example in the verification of results of computer simulations of the low frequency Doppler signal processing. The software of SINA and its use are explained.

    The characteristic length of the magnetic proximity effects exceed the thickness of a graphene layer leading to an important, but typically overlooked, modifications of equilibrium and transport properties, as well as the implications for graphene spintronics. Using the first-principles studies that integrate a real space density functional theory (GPAW) with the state-of-the art boundary elements electrostatic code based on the Robin Hood method, we explore tunable electronic structure and magnetic proximity effects in the ferromagnet/insulator/graphene junctions. We show that the inclusion of a finite-size gate electrodes and van der Walls interaction lead to nontrivial effects that could also be important in other two-dimensional materials beyond graphene.

    Full Text Available Notwithstanding the recent success in major limb replantation achieved through the advancements in microsurgical techniques, the viability of the extremity is still relatively low at the transhumeral level following a replantation. There are no exact guidelines for deciding whether to undertake a stump repair or a replantation in such amputations at the proximal level. However, a highly motivated patient with realistic expectations and protected shoulder function can be a candidate to undergo replantation. The replanted arm may help the uninjured arm in daily activities. In this report we present the case of a 47-year-old man whose arm was amputated at proximal third level by an asphalt machine and successfully replanted together with the encountered problems and their solutions. The roadmap followed in this rare case may be a guide for hand surgeons.

    Full Text Available Dedifferentiated chondrosarcoma (DDCS comprises approximately 10% of all chondrosarcomas. The tumor generally occurs after the age of 50 years, with equal distribution among males and females. It is most often located in the bones of the pelvis, the proximal femur or humerus, the distal femur, and the ribs. Regardless of treatment, the prognosis is ominous with 90% of patients dying with distant metastases within 2 years. We report a case of DDCS of right proximal femur in a 73-year-old woman. The most important factors affecting survival are early recognition of the radiographic features, adequate histological sampling, and wide-margin resection of the lesion. So for the correct histopathological diagnosis the biopsy sample should be adequate to visualize both cartilaginous and noncartilaginous sarcomatous component which helps to increase the survival of patients before the distant metastasis occurs.

    To validate the Dudley Inflammatory Bowel Disease Questionnaire (DISQ) for determining the presence and severity of bowel symptoms in axial SpA. Seventy-seven SpA patients were assessed for disease activity using the BASDAI. All participants, including 32 healthy controls and 29 patients with Crohn's Disease (CD), completed the DISQ and an assessment of stool form and frequency. Validation of the DISQ was undertaken in accordance with OMERACT criteria. Validity of the DISQ for measuring bowel symptoms in SpA was confirmed (Cronbach's α 0.79). Mean DISQ scores (s.d.) were: controls 2.6 (2.6), SpA 8.7 (6.1) and CD 17.1 (10.2). Differences were significant between controls and SpA, and SpA and CD, and correlated with disease activity (ρ 0.27, P = 0.02). In SpA, DISQ scores of those taking NSAIDs (n = 59) did not differ from those not taking NSAIDs (n = 18) (P = 0.31). Stool form and frequency differed significantly between SpA patients and healthy controls (P SpA is 31%, and 7.8% experience bowel symptoms equivalent to active CD. The DISQ is a valid measure of bowel symptoms in SpA. Bowel symptoms are prevalent in SpA and correlate with disease activity. Symptoms do not relate to treatment with NSAIDs. We conclude that bowel symptoms should be included as a domain in the clinical assessment of patients with SpA and that the DISQ has potential as an outcome measure in clinical trials.

    Proximal humeral fractures, which typically occur in elderly persons, are among the most common fractures. A myriad of nonsurgical and surgical treatment options exist for these injuries, including short-term immobilization and early physical therapy, percutaneous fixation, plate osteosynthesis, intramedullary nailing, hemiarthroplasty, and reverse shoulder arthroplasty. The choice of treatment depends on the fracture type and severity, surgeon expertise, patient age, and patient health status.

    We investigate the superconducting proximity effect in clean ferromagnetic layers with rough boundaries. The subgap density of states is formed by Andreev bound states at energies which depend on trajectory length and the ferromagnetic exchange field. At energies above the gap, the spectrum is governed by resonant scattering states. The resulting density of states, measurable by tunneling spectroscopy, exhibits a rich structure, which allows us to connect the theoretical parameters from exper...

    International audience; We consider a variational formulation of blind image recovery problems. A novel iterative proximal algorithm is proposed to solve the associated nonconvex minimization problem. Under suitable assumptions, this algorithm is shown to have better convergence properties than standard alternating minimization techniques. The objective function includes a smooth convex data fidelity term and nonsmooth convex regularization terms modeling prior information on the data and on ...

    Abstract Among stress fractures associated with sports activities, patellar stress fracture is rare. Regarding patella stress fractures, so far only distal transverse or lateral longitudinal fractures have been reported, but there are no reports of transverse fractures occurring in the proximal patella. We describe an extremely rare case of transverse stress fracture of proximal patella in a 9-year-old athlete. A 9-year old boy, who participated in sports (sprints and Kendo) presented with left knee pain without any external injury. In plain radiographs, a fracture line was observed in the proximal 1/3 of the left patella, and a patella stress fracture was diagnosed. For treatment, because 7 months of conservative therapy showed no improvement, internal fixation was carried out using Acutrak screws, and bone union was thus achieved. Three months after the operation, he was able to return to his previous level of athletic sports activity. Regarding the mechanism of onset, it is believed that the causes are longitudinal traction force and patellofemoral contact pressure. On the other hand, the contact region of the patella with the femur changes with the flexion angle of the knee. In the current case, the fracture occurred at a site where the patella was in contact with the femur at a flexion angle of >90°, so it is believed that it occurred as a clinical condition from being subjected to repeated longitudinal traction force and patellofemoral contact pressure at a flexion angle of >90°, during the sports activities of sprints and Kendo. The nonunion of the transverse stress fracture of his proximal patella was successfully treated with internal fixation using Acutrak screws. PMID:26871789

  16. Proximal Gastrojejunal Reconstruction after Pancreaticoduodenal Resection

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Introduction. Reconstruction by proximal gastrojejunostomy, and distal biliary and pancreatic anastomoses is infrequently used after resection of the head of the pancreas because of fear of fistulas and cholangitis. Pancreaticoduodenectomy is being performed more frequently for cystic malignant and premalignant lesions. Because of this there is a need for endoscopic visualization and biopsy of the residual pancreatic duct, since multi-centricity is characteristic of some of these malignancies. Since endoscopic access of the bile duct and pancreatic duct is difficult and unsuccessful in 50–70% after B II or Roux Y reconstruction, we prospectively studied the merit and complications (early and late of proximal gastrojejunal (PGJ reconstruction after pancreaticoduodenal resection. Material and Methods. Thirty nine consecutive, non-radomized patients underwent pancreaticoduodenectomy and PGJ reconstruction over 14 mos. There were 21 males and 18 females. Results. 7 patients with IPMN have undergone repeat CT scanning for surveillance, with 3 requiring repeat EUS and ERCP. There were no technical difficulties accessing the pancreas or the pancreatic duct, supporting the PGJ reconstruction. Conclusion. Proximal gastrojejunal reconstruction following pancreaticoduodenal resection may be safely done with similar morbidity to traditional pancreaticojejunal reconstructions. PGJ reconstruction may be of greater value when direct visual access to the bile duct or pancreatic duct is necessary, and should be considered when doing resection for mucinous cysts or IPMN of the head of the pancreas.

    Dislocation of the tibiofibular joint is rare and usually results from a traumatic event. Only 1 case of atraumatic proximal tibiofibular joint instability in a 14-year-old girl has been reported in the literature, however this condition might occur more frequently than once thought. A wide range of treatment options exist for tibiofibular dislocations. Currently, the first choice is a conservative approach, and when this fails, surgical means such as resection of the fibula head, arthrodesis, and reconstruction are considered. However, no consensus exists on the most effective treatment. This article reports a unique case of bilateral, atraumatic, proximal tibia and fibular joint instability involving a 30-year-old man with a 20-year history of pain and laxity in the right knee. The patient had no trauma to his knees; he reported 2 immediate family members with similar complaints, which suggests that this case is likely congenital. After conservative approaches proved to be ineffective, the patient underwent capsular reconstruction using free autologous gracilis tendon. At 6-month postoperative follow-up, the patient was pain free with no locking and instability. He then underwent surgery on the left knee. At 1-year follow-up after the second surgery, the patient had no symptoms or restrictions in mobility. We provide an alternative surgical approach to arthrodesis and resection for the treatment of chronic proximal tibiofibular instability. In the treatment of chronic tibiofibular instability, we believe that reconstruction of the tibiofibular joint is a safe and effective choice. Copyright 2011, SLACK Incorporated.

    Growing interest in the structure and dynamics of animal social networks has stimulated efforts to develop automated tracking technologies that can reliably record encounters in free-ranging subjects. A particularly promising approach is the use of animal-attached 'proximity loggers', which collect data on the incidence, duration and proximity of spatial associations through inter-logger radio communication. While proximity logging is based on a straightforward physical principle - the attenuation of propagating radio waves with distance - calibrating systems for field deployment is challenging, since most study species roam across complex, heterogeneous environments.In this study, we calibrated a recently developed digital proximity-logging system ('Encounternet') for deployment on a wild population of New Caledonian crows Corvus moneduloides. Our principal objective was to establish a quantitative model that enables robust post hoc estimation of logger-to-logger (and, hence, crow-to-crow) distances from logger-recorded signal-strength values. To achieve an accurate description of the radio communication between crow-borne loggers, we conducted a calibration exercise that combines theoretical analyses, field experiments, statistical modelling, behavioural observations, and computer simulations.We show that, using signal-strength information only, it is possible to assign crow encounters reliably to predefined distance classes, enabling powerful analyses of social dynamics. For example, raw data sets from field-deployed loggers can be filtered at the analysis stage to include predominantly encounters where crows would have come to within a few metres of each other, and could therefore have socially learned new behaviours through direct observation. One of the main challenges for improving data classification further is the fact that crows - like most other study species - associate across a wide variety of habitats and behavioural contexts, with different signal

    Staphylococcus aureus belongs to one of the most common bacteria causing healthcare and community associated infections in China, but their molecular characterization has not been well studied. From May 2011 to June 2012, a total of 322 non-duplicate S. aureus isolates were consecutively collected from seven tertiary care hospitals in seven cities with distinct geographical locations in China, including 171 methicillin sensitive S. aureus (MSSA) and 151 MRSA isolates. All isolates were characterized by spa typing. The presence of virulence genes was tested by PCR. MRSA were further characterized by SCCmec typing. Seventy four and 16 spa types were identified among 168 MSSA and 150 MRSA, respectively. One spa type t030 accounted for 80.1% of all MRSA isolates, which was higher than previously reported, while spa-t037 accounted for only 4.0% of all MRSA isolates. The first six spa types (t309, t189, t034, t377, t078 and t091) accounted for about one third of all MSSA isolates. 121 of 151 MRSA isolates (80.1%) were identified as SCCmec type III. pvl gene was found in 32 MSSA (18.7%) and 5 MRSA (3.3%) isolates, with ST22-MSSA-t309 as the most commonly identified strain. Compared with non-epidemic MRSA clones, epidemic MRSA clones (corresponding to ST239) exhibited a lower susceptibility to rifampin, ciprofloxacin, gentamicin and trimethoprim-sulfamethoxazole, a higher prevalence of sea gene and a lower prevalence of seb, sec, seg, sei and tst genes. The increasing prevalence of multidrug resistant spa-t030 MRSA represents a major public health problem in China.

    In using spectroscopy to quantitatively or qualitatively analyze the quality of fruit, how to obtain a simple and effective correction model is very critical for the application and maintenance of the developed model. Strawberry as the research object, this research mainly focused on selecting the key variables and characteristic samples for quantitatively determining the soluble solids content. Competitive adaptive reweighted sampling (CARS) algorithm was firstly proposed to select the spectra variables. Then, Samples of correction set were selected by successive projections algorithm (SPA), and 98 characteristic samples were obtained. Next, based on the selected variables and characteristic samples, the second variable selection was performed by using SPA method. 25 key variables were obtained. In order to verify the performance of the proposed CARS algorithm, variable selection algorithms including Monte Carlo-uninformative variable elimination (MC-UVE) and SPA were used as the comparison algorithms. Results showed that CARS algorithm could eliminate uninformative variables and remove the collinearity information at the same time. Similarly, in order to assess the performance of the proposed SPA algorithm for selecting the characteristic samples, SPA algorithm was compared with classical Kennard-Stone algorithm Results showed that SPA algorithm could be used for selection of the characteristic samples in the calibration set. Finally, PLS and MLR model for quantitatively predicting the SSC (soluble solids content) in the strawberry were proposed based on the variables/samples subset (25/98), respectively. Results show that models built by using the 0.59% and 65.33% information of original variables and samples could obtain better performance than using the ones obtained by using all information of the original variables and samples. MLR model was the best with R(pre)2 = 0.9097, RMSEP=0.3484 and RPD = 3.3278.

  1. Smooth pursuit adaptation (SPA) exhibits features useful to compensate changes in the properties of the smooth pursuit eye movement system due to usage.

    Dash, Suryadeep; Thier, Peter

    2013-01-01

    Smooth-pursuit adaptation (SPA) refers to the fact that pursuit gain in the early, still open-loop response phase of the pursuit eye movement can be adjusted based on experience. For instance, if the target moves initially at a constant velocity for ~100-200 ms and then steps to a higher velocity, subjects learn to up-regulate the pursuit gain associated with the initial target velocity (gain-increase SPA) in order to reduce the retinal error resulting from the velocity step. Correspondingly, a step to a lower target velocity leads to a decrease in gain (gain-decrease SPA). In this study we demonstrate that the increase in peak eye velocity during gain-increase SPA is a consequence of expanding the duration of the eye acceleration profile while the decrease in peak velocity during gain-decrease SPA results from reduced peak eye acceleration but unaltered duration. Furthermore, we show that carrying out stereotypical smooth pursuit eye movements elicited by constant velocity target ramps for several hundred trials (=test of pursuit resilience) leads to a clear drop in initial peak acceleration, a reflection of oculomotor and/or cognitive fatigue. However, this drop in acceleration gets compensated by an increase in the duration of the acceleration profile, thereby keeping initial pursuit gain constant. The compensatory expansion of the acceleration profile in the pursuit resilience experiment is reminiscent of the one leading to gain-increase SPA, suggesting that both processes tap one and the same neuronal mechanism warranting a precise acceleration-duration trade-off. Finally, we show that the ability to adjust acceleration duration during pursuit resilience depends on the integrity of the oculomotor vermis (OMV) as indicated by the complete loss of the duration adjustment following a surgical lesion of the OMV in one rhesus monkey we could study.

  2. SpA, ClfA, and FnbA Genetic Variations Lead to Staphaurex Test-Negative Phenotypes in Bovine Mastitis Staphylococcus aureus Isolates▿

    Staphylococcus aureus encodes many proteins that act as virulence factors, leading to a variety of diseases, including mastitis in cows. Among these virulence factors, SpA, ClfA, ClfB, FnbA, and FnbB are important for the ability of S. aureus to adhere to and invade host cells as well as to evade host immune responses. The interaction between these S. aureus surface proteins and human immunoglobulin G and fibrinogen that are coupled to latex particles is utilized to induce latex agglutination reactions, which are used widely in diagnostic kits for confirmation of presumptive S. aureus isolates. In this study, the Staphaurex latex agglutination test was performed on a collection of confirmed bovine mastitis S. aureus isolates. Notably, 54% (43/79 isolates) of these isolates exhibited latex agglutination-negative phenotypes (Staphaurex-negative result). To gain insights into the reasons for the high frequency of Staphaurex-negative bovine mastitis S. aureus isolates, the spa, clfA, clfB, fnbA, and fnbB genes were examined. Specific genetic changes in spa, clfA, and fnbA, as well as a loss of fnbB, which may impair SpA, ClfA, FnbA, and FnbB functions in latex agglutination reactions, were detected in Staphaurex-negative S. aureus isolates. The genetic changes included a premature stop codon in the spa gene, leading to a truncated SpA protein that is unable to participate in S. aureus cell-mediated agglutination of latex particles. In addition, clfA and fnbA genetic polymorphisms were detected that were linked to ClfA and FnbA amino acid changes that may significantly reduce fibrinogen-binding activity. The genetic variations in these S. aureus isolates might also have implications for their bovine mastitis virulence capacity. PMID:21147952

    Staphylococcus aureus is a leading cause of bacteremia in hospitalized patients. Whether or not S. aureus bacteremia (SAB) is associated with clonality, implicating potential nosocomial transmission, has not, however, been investigated. Herein, we examined the epidemiology of SAB using whole genome sequencing (WGS). 152 SAB isolates collected over the course of 2015 at a single large Minnesota medical center were studied. Staphylococcus protein A (spa) typing was performed by PCR/Sanger sequencing; multilocus sequence typing (MLST) and core genome MLST (cgMLST) were determined by WGS. Forty-eight isolates (32%) were methicillin-resistant S. aureus (MRSA). The isolates encompassed 66 spa types, clustered into 11 spa clonal complexes (CCs) and 10 singleton types. 88% of 48 MRSA isolates belonged to spa CC-002 or -008. Methicillin-susceptible S. aureus (MSSA) isolates were more genotypically diverse, with 61% distributed across four spa CCs (CC-002, CC-012, CC-008 and CC-084). By MLST, there was 31 sequence types (STs), including 18 divided into 6 CCs and 13 singleton STs. Amongst MSSA isolates, the common MLST clones were CC5 (23%), CC30 (19%), CC8 (15%) and CC15 (11%). Common MRSA clones were CC5 (67%) and CC8 (25%); there were no MRSA isolates in CC45 or CC30. By cgMLST analysis, there were 9 allelic differences between two isolates, with the remaining 150 isolates differing from each other by over 40 alleles. The two isolates were retroactively epidemiologically linked by medical record review. Overall, cgMLST analysis resulted in higher resolution epidemiological typing than did multilocus sequence or spa typing.

    Far infrared radiation, a subdivision of the electromagnetic spectrum, is beneficial for long-term tissue healing, anti-inflammatory effects, growth promotion, sleep modulation, acceleration of microcirculation, and pain relief. We investigated if far infrared radiation is beneficial for renal proximal tubule cell cultivation and renal tissue engineering. We observed the effects of far infrared radiation on renal proximal tubules cells, including its effects on cell proliferation, gene and protein expression, and viability. We also examined the protective effects of far infrared radiation against cisplatin, a nephrotoxic agent, using the human proximal tubule cell line HK-2. We found that daily exposure to far infrared radiation for 30 min significantly increased rabbit renal proximal tubule cell proliferation in vitro, as assessed by MTT assay. Far infrared radiation was not only beneficial to renal proximal tubule cell proliferation, it also increased the expression of ATPase Na+/K+ subunit alpha 1 and glucose transporter 1, as determined by western blotting. Using quantitative polymerase chain reaction, we found that far infrared radiation enhanced CDK5R1, GNAS, NPPB, and TEK expression. In the proximal tubule cell line HK-2, far infrared radiation protected against cisplatin-mediated nephrotoxicity by reducing apoptosis. Renal proximal tubule cell cultivation with far infrared radiation exposure resulted in better cell proliferation, significantly higher ATPase Na+/K+ subunit alpha 1 and glucose transporter 1 expression, and significantly enhanced expression of CDK5R1, GNAS, NPPB, and TEK. These results suggest that far infrared radiation improves cell proliferation and differentiation. In HK-2 cells, far infrared radiation mediated protective effects against cisplatin-induced nephrotoxicity by reducing apoptosis, as indicated by flow cytometry and caspase-3 assay.

    Fibrinolysis is an important and integral part of the hemostatic system. Acting as a balance to blood coagulation, the fibrinolytic system protects the body from unwanted thrombus formation and occlusion of blood vessels. As long as blood coagulation and fibrinolysis remain in equilibrium, response to injury, such as vessel damage, is appropriately regulated. However, alterations in this balance may lead to thrombosis or bleeding. A variety of methods have been proposed to assess fibrinolytic activity in blood or its components, but due to the complexity of the system, the design of a "gold standard" assay that reflects overall fibrinolysis has remained an elusive goal. In this review, we describe the most commonly used methods that have been described, such as thromboelastography (TEG and ROTEM), global fibrinolytic capacity in plasma and whole blood, plasma turbidity methods, simultaneous thrombin and plasmin generation assays, euglobulin clot lysis time and fibrin plate methods. All of these assays have strengths and limitations. We suggest that some methods may be preferable for detecting hypofibrinolytic conditions, whereas others may be better for detecting hyperfibrinolytic states. © 2017 John Wiley & Sons Ltd.

    To assess the prevalence of sex work and its associations with substance use among female bar/spa workers in the Philippines (N = 498), workers from 54 bar or spa venues in Metro Manila (2009-2010) were surveyed on demographics, drug/alcohol use, abuse history, and sex work. Their median age was 23 years and 35% engaged in sex work. Sex work was independently associated with methamphetamine use (19% vs 4%; adjusted odds ratio [AOR] =2.9, 95% confidence interval [CI] = 1.3-6.2), alcohol use with patrons (49% vs. 27%; AOR = 1.9, 95% CI = 1.1-3.4), and alcohol intoxication during sex (50% vs. 24%; AOR = 2.0, 95% CI = 1.2-3.5), but inversely associated with daily alcohol use (13% vs. 16%; AOR = 0.2, 95% CI = 0.1-0.5). Additional significant covariates included sexual abuse history, younger age, and not having a higher education. Findings suggest that interventions with sex workers in bars and spas should focus on methamphetamine use, alcohol use contexts, and violence victimization, to better meet the needs of this population.

    Full Text Available Introduction: The association between Sleep Obstructive Apnea Syndrome (SOAS and the obesity has been highly studied. The SOAS is characterized by the repetitive obstruction of the upper airways during the sleep, many times accompanied by snores, oxygen desaturation, sleep fragmentation and excessive daytime somnolence (EDS. Type of Study: Prospective Transversal. Objective: To analyze the results of the Berlin Questionnaire (BQ and the Epworth Somnolence Scale (ESS completed by the patients interned in the Spa Med Campus Sorocaba, attempting to find who has daytime somnolence and high risk for SOAS. Method: The patients completed the Berlin Questionnaire and the ESS voluntarily. The study was of transversal type with analysis of the questionnaires completed during the year of 2008. Results: We obtained a total of 276 patients with a total of 183 women and 93 men. The prevalence of obese patients was of 111 patients (40.2%. In the positive BQ group, we obtained a total of 84 patients; 34 male; as to the positive ESS group, we found a total of 67 patients, 24 male. Conclusion: The ESS and the BQ have been useful currently for selection of the sleep disorders and may serve as a possible indicator for polysonography. The questionnaires' results show us the high prevalence of individuals interned in SPA with the risk of having SOAS, specially the obese ones.

    A novel type of very fast nucleation was recently found in Pb/Si(111) with 4- to 7-layer high islands becoming crystalline in an "explosive" way, when the Pb deposited amount in the wetting layer is compressed to θc 1.22 ML, well above the metallic Pb(111) density. This "explosive" nucleation is very different from classical nucleation when island growth is more gradual and islands grow in size by single adatom aggregation [8]. In order to identify the key parameters that control the nucleation we used scanning tunneling microscopy (STM) and spot profile analysis low energy electron diffraction (SPA-LEED). It was found that the number and duration of steps in iterative deposition used to approach θc and the flux rate have dramatic effects on the crystallization process. Larger depositions over shorter times induce greater spatial coverage fluctuations, so local areas can reach the critical coverage θc easier. This can trigger the collective motion of the wetting layer from far away to build the Pb islands "explosively". The SPA-LEED experiments show that even low flux experiments in iterative deposition experiments can trigger transfer of material to the superstable 7-layer islands, as seen from the stronger satellite rings close to the (00) spot.

    Ankylosing spondylitis (AS) can cause severe functional disorders that lead to loss of balance. The aim of this study was to investigate the effects of balance and postural stability exercises on spa based rehabilitation programme in AS subjects. Twenty-one participants were randomized to the study (n= 11) and control groups (n= 10). Patients balance and stability were assessed with the Berg Balance Scale (BBS), Timed Up and Go (TUG) Test, Single Leg Stance Test (SLST) and Functional Reach Test (FRT). AS spesicied measures were used for assessing to other parameters. The treatment plan for both groups consisted of conventional transcutaneous electrical nerve stimulation (TENS), spa and land-based exercises 5 days per week for 3 weeks. The study group performed exercises based on postural stability and balance with routine physiotherapy practice in thermal water and in exercise room. The TUG, SLST and FUT scores were significantly increased in the study group. In both groups, the BASMI, BASFI, BASDAI and ASQoL scores decreased significantly by the end of the treatment period (pspa based routine approaches can increase the duration of maintaining balance and can improve the benefits of physiotherapy.

    The purpose of the study was to investigate the molecular characteristics of meticillin-resistant Staphylococcus aureus (MRSA) isolated from clinical sources in Tripoli, Libya. A total of 95 MRSA strains collected at the Tripoli medical Centre were investigated by spa typing and identification of the Panton-Valentine Leukocidin (pvl) genes. A total of 26 spa types were characterized and distributed among nine clonal complexes; CC5 (n=32), CC80 (n=18), CC8 (n=17) and CC22 (n=12) were the most prevalent clonal complexes. In total, 34% of the isolates were positive for PVL. This study demonstrated the presence of CA-MRSA and pvl positive strains in hospital settings and underlines the importance of using molecular typing to investigate the epidemiology of MRSA. Preventative measures and surveillance systems are needed to control and minimize the spread of MRSA in the Libyan health care system.

    1981-10-26

    The purpose of this study is to determine the engineering and economic feasibility for utilizing geothermal energy for air conditioning and service water heating at the Wine Valley Inn, a mineral water spa in Calistoga, California. The study evaluates heating, ventilating, air conditioning and water heating systems suitable for direct heat geothermal application. Due to the excellent geothermal temperatures available at this site, the mechanics and economics of a geothermally powered chilled water cooling system are evaluated. The Wine Valley Inn has the resource potential to have one of the few totally geothermal powered air conditioning and water heating systems in the world. This total concept is completely developed. A water plan was prepared to determine the quantity of water required for fresh water well development based on the special requirements of the project. An economic evaluation of the system is included to justify the added capital investment needed to build the geothermally powered mineral spa. Energy payback calculations are presented. A thermal cascade system is proposed to direct the geothermal water through the energy system to first power the chiller, then the space heating system, domestic hot water, the two spas and finally to heat the swimming pool. The Energy Management strategy required to automatically control this cascade process using industrial quality micro-processor equipment is described. Energy Management controls are selected to keep equipment sizing at a minimum, pump only the amount of geothermal water needed and be self balancing.

    2011-01-01

    Full Text Available In this paper we have examined the effect of variable frequency electromagnetic field generated with a homemade device on deposit formation in installations with geothermal water from Sijarinjska Spa. The frequency alteration of the electromagnetic field in time was made by means of the sinusoidal and saw-tooth function. In laboratory conditions, with the flow of geothermal water at 0.015 l/s and temperature of 60 °C for 6 hours through a zig-zag glass pipe, a multiple decrease of total deposit has been achieved. By applying the saw-tooth and sinusoidal function, the decrease in contents of calcium and deposit has been achieved by 8 and 6 times, respectively. A device was also used on geothermal water installation in Sijarinjska Spa (Serbia, with the water flow through a 1'' diameter non-magnetic prochrome pipe at 0.15 l/s and temperature of 75 °C in a ten-day period. A significant decrease in total deposit and calcium in the deposit has also been achieved.

    The aim of current study was to examine clonal structure and genetic profile of invasive Staphylococcus aureus isolates recovered from infants and children treated at the Jagiellonian University Children's Hospital of Krakow, Poland. The 107 invasive S. aureus isolates, collected between February 2012 and August 2014, were analysed retrospectively. Antimicrobial susceptibility testing, spa typing and DNA microarray analysis were performed to determine clonal distribution, diversity and gene content in regard to patients characteristics. In total, 107 isolates were recovered from 88 patients with clinical symptoms of invasive bacterial infection. The final set of 92 non-duplicate samples included 38 MRSA isolates. Additionally, a set of 54 S. aureus isolates collected during epidemiological screening was genotyped and analysed. There were 72 healthcare-associated (HCA) and 20 community-onset (CO) infection events caused by 33 and 5 MRSA isolates, respectively. The majority of isolates were affiliated with the major European clonal complexes CC5 (t003, spa-CC 002), CC45 (spa-CC 015), CC7 or CC15 (t084, t091, spa-CC 084). Two epidemic clones (CC5-MRSA-II or CC45-MRSA-IV) dominated among MRSA isolates, while MSSA population contained 15 different CCs. The epidemiological screening isolates belonged to similar genetic lineages as those collected from invasive infection cases. The HCA infection events, spa types t003, t2642 or CC5 were significantly associated with infections occurring in neonates and children under 5 years of age. Moreover, carriage of several genetic markers, including erm(A), sea (N315), egc-cluster, chp was significantly higher in isolates obtained from children in this age group. The spa types t091 and t008 were underrepresented among patients aged 5 years or younger, whereas spa type t008, CC8 and presence of splE was associated with infection in children aged 10 years or older. The HCA-MRSA strains were most frequently found in children under 5

  4. Delayed homicides and the proximate cause.

    Science.gov (United States)

    Lin, Peter; Gill, James R

    2009-12-01

    Delayed homicides result from complications of remote injuries inflicted by "the hands of another." The investigation of delayed homicides may be a challenge due to a number of factors including: failure to report the death to the proper authorities, lack of ready and adequate documentation of the original injury and circumstances, and jurisdictional differences between the places of injury and death. The certification of these deaths also requires the demonstration of a pathophysiologic link between the remote injury and death. In sorting through these issues, it is helpful to rely upon the definition of the proximate cause of death. Over a 2-year period in New York City, there were 1211 deaths certified as homicide of which 42 were due to injuries sustained greater than 1 year before death. The survival interval ranged from 1.3 to 43.2 years. The most common immediate causes of death were: infections (22), seizures (7), and intestinal obstructions/hernias (6). Common patterns of complications included infection following a gunshot wound of the spinal cord, seizure disorder due to blunt head trauma, and intestinal obstruction/hernia due to adhesions from an abdominal stab wound. Spinal cord injuries resulted in paraplegia in 14 instances and quadriplegia in 8. The mean survival interval for paraplegics was 20.3 years and 14.8 years for quadriplegics; infections were a frequent immediate cause of death in both groups, particularly infections due to chronic bladder catheterization. The definition of proximate cause originated with civil law cases and was later applied to death certification as the proximate cause of death. The gradual extinction of the "year and a day rule" for the limitation of bringing homicide charges in delayed deaths may result in more of these deaths going to trial. Medical examiners/coroners must be able to explain the reasoning behind these death certifications and maintain consistent standards for the certification of all delayed deaths due

    Proximal early gastric cancer is a good indication for totally laparoscopic proximal gastrectomy (TLPG) with double-tract reconstruction (DTR). However, when most of the dietary intake passes through the escape route of the jejunum, the functional benefits of proximal gastrectomy might be similar to those after total gastrectomy. Our DTR procedure was improved for easy passage through the remnant stomach. The purposes of this study were to present a novel technique for intracorporeal DTR using linear staplers after TLPG and to investigate surgical outcomes. DTR was performed using linear staplers only. A side-to-side jejunogastrostomy with twisting of both the remnant stomach and the anal jejunum was performed for the purpose of passing meals through the remnant stomach (an oblique jejunogastrostomy technique). The ten patients who underwent TLPG with DTR from January 2011 to August 2016 in Hokkaido University Hospital were retrospectively reviewed. Their clinicopathological characteristics and surgical and postoperative outcomes were collected and analyzed. The median duration of operation was 285 (range 146-440) min. No patients required blood transfusions. The number of dissected lymph nodes was 32 (range 22-56). There were no intraoperative complications, and no cases were converted to open surgery. All the patients were pT1N0M0 stage IA. No anastomotic leakage or complications were detected. Postoperative gastrography after reconstruction showed that contrast medium flowed mainly to the remnant stomach. The average percentage body weight loss was 14.0 ± 7.1% at 10 months. The average percentage decrease in serum hemoglobin was 5.4 ± 10.4% at 12 months. This novel technique for intracorporeal DTR provided a considerable advantage by the passage of dietary intake to the remnant stomach after LPG.

    1986-10-01

    Stripped segments of proximal colon (1-6 cm distal to the ampulla caecalis coli) were studied in vitro in Ussing chambers under short-circuit conditions using the pH-stat technique. With glucose and HCO3-CO2 present in the serosal bathing solution only, proximal colon alkalinizes the luminal bathing solution at a rate of 2.1 +/- 0.2 mu eq X h-1 X cm-2 (n = 36). With HCO3-CO2 present in the luminal bathing solution alone, proximal colon does not significantly acidify or alkalinize the serosal bathing solution. Addition of glucose (10 mM) to the luminal bathing solution abolished luminal alkalinization. Removal of HCO3 and CO2 from the serosal bathing solution or replacement of O2 with N2 also abolished luminal alkalinization. Acetazolamide (0.1 mM) added to both bathing solutions did not alter the rate of luminal alkalinization. Ion-replacement studies revealed that the alkalinization process was highly dependent on the presence of Na in the bathing solutions and much less dependent on the presence of Cl. Furthermore, ouabain (0.1 mM) significantly reduced luminal alkalinization. As in rabbit ileum, serosal epinephrine (0.1 mM) did not alter luminal alkalinization but increased serosal alkalinization by a Na-dependent mechanism. These results suggest that luminal alkalinization results from a Na-dependent, active transcellular HCO3 transport process and that a Na-dependent HCO3 absorptive process is activated by adrenergic stimuli.

  7. Temporal Proximity Promotes Integration of Overlapping Events.

    Events with overlapping elements can be encoded as two separate representations or linked into an integrated representation, yet we know little about the conditions that promote one form of representation over the other. Here, we tested the hypothesis that the proximity of overlapping events would increase the probability of integration. Participants first established memories for house-object and face-object pairs; half of the pairs were learned 24 hr before an fMRI session, and the other half 30 min before the session. During scanning, participants encoded object-object pairs that overlapped with the initial pairs acquired on the same or prior day. Participants were also scanned as they made inference judgments about the relationships among overlapping pairs learned on the same or different day. Participants were more accurate and faster when inferring relationships among memories learned on the same day relative to those acquired across days, suggesting that temporal proximity promotes integration. Evidence for reactivation of existing memories-as measured by a visual content classifier-was equivalent during encoding of overlapping pairs from the two temporal conditions. In contrast, evidence for integration-as measured by a mnemonic strategy classifier from an independent study [Richter, F. R., Chanales, A. J. H., & Kuhl, B. A. Predicting the integration of overlapping memories by decoding mnemonic processing states during learning. Neuroimage, 124, 323-335, 2016]-was greater for same-day overlapping events, paralleling the behavioral results. During inference itself, activation patterns further differentiated when participants were making inferences about events acquired on the same day versus across days. These findings indicate that temporal proximity of events promotes integration and further influences the neural mechanisms engaged during inference.

    Interactions between proteins are essential for fundamental cellular processes, and the diversity of such interactions enables the vast variety of functions essential for life. A persistent goal in biological research is to develop assays that can faithfully capture different types of protein interactions to allow their study. A major step forward in this direction came with a family of methods that delineates spatial proximity of proteins as an indirect measure of protein-protein interaction. A variety of enzyme- and DNA ligation-based methods measure protein co-localization in space, capturing novel interactions that were previously too transient or low affinity to be identified. Here we review some of the methods that have been successfully used to measure spatially proximal protein-protein interactions. Copyright © 2017 The Authors. Published by Elsevier Inc.

    2016-04-01

    Full Text Available Impacted valgus fractures of the proximal humerus are considered to be a special type fracture, since impaction of the humeral head on the metaphysis with maintenance of the posteromedial periosteum improves the prognosis regarding occurrences of avascular necrosis. This characteristic can also facilitate the reduction maneuver and increase the consolidation rate of these fractures, even in more complex cases. The studies included were obtained by searching the Bireme, Medline, PubMed, Cochrane Library and Google Scholar databases for those published between 1991 and 2013. The objective of this study was to identify the most common definitions, classifications and treatment methods used for these fractures in the orthopedic medical literature.

    Chronic flexion contracture of the proximal interphalangeal (PIP) joint presents a common yet challenging problem to hand surgeons. Over the years, multiple treatment modalities have been described for this problem, producing limited results. Nonoperative treatment using serial casting and splints should be tried before attempting open surgical release, which should be done in selected patients. The use of external fixation for treating PIP contracture has been encouraging and can be a useful alterative. This review provides an update on the current management of PIP joint contractures and presents a flowchart of treatment to aid decision making.

    2014-01-01

    Urea transport in the proximal tubule is passive and is dependent on the epithelial permeability. The present study examined the maturation of urea permeability (Purea) in in vitro perfused proximal convoluted tubules (PCT) and basolateral membrane vesicles (BLMV) from rabbit renal cortex. Urea transport was lower in neonatal than adult PCT at both 37 and 25°C. The PCT Purea was also lower in the neonates than the adults (37°C: 45.4 ± 10.8 vs. 88.5 ± 15.2 × 10−6 cm/s, P 0.05). The activation energy for PCT Purea was not different between the neonatal and adult groups. BLMV Purea was determined by measuring vesicle shrinkage, due to efflux of urea, using a stop-flow instrument. Neonatal BLMV Purea was not different from adult BLMV Purea at 37°C [1.14 ± 0.05 × 10−6 vs. 1.25 ± 0.05 × 10−6 cm/s; P = not significant (NS)] or 25°C (0.94 ± 0.06 vs. 1.05 ± 0.10 × 10−6 cm/s; P = NS). There was no effect of 250 μM phloretin, an inhibitor of the urea transporter, on Purea in either adult or neonatal BLMV. The activation energy for urea diffusion was also identical in the neonatal and adult BLMV. These findings in the BLMV are in contrast to the brush-border membrane vesicles (BBMV) where we have previously demonstrated that urea transport is lower in the neonate than the adult. Urea transport is lower in the neonatal proximal tubule than the adult. This is due to a lower rate of apical membrane urea transport, whereas basolateral urea transport is the same in neonates and adults. The lower Purea in neonatal proximal tubules may play a role in overall urea excretion and in developing and maintaining a high medullary urea concentration and thus in the ability to concentrate the urine during renal maturation.

    The SNO+ experiment will study neutrinos while located 6,800 feet below the surface of the earth at SNOLAB. Though shielded from surface backgrounds, emanation of radon radioisotopes from the surrounding rock leads to back-grounds. The characteristic decay of radon and its daughters allows for an alpha detection technique to count the amount of Rn-222 atoms collected. Traps can collect Rn-222 from various positions and materials, including an assay skid that will collect Rn-222 from the organic liquid scintillator used to detect interactions within SNO+.

  15. Chemiluminescence assay for the detection of biological warfare agents

    Energy Technology Data Exchange (ETDEWEB)

    Langry, K; Horn, J

    1999-11-05

    A chemiluminescent homogeneous immunoassay and a hand-size multiassay reader are described that could be used for detecting biological materials. The special feature of the assay is that it employs two different antibodies that each bind to a unique epitope on the same antigen. Each group of epitope-specific antibodies has linked to it an enzyme of a proximal-enzyme pair. One enzyme of the pair utilizes a substrate in high concentration to produce a second substrate required by the second enzyme. This new substrate enables the second enzyme to function. The reaction of the second enzyme is configured to produce light. This chemiluminescence is detected with a charge-coupled device (CCD) camera. The proximal pair enzymes must be in close proximity to one another to allow the second enzyme to react with the product of the first enzyme. This only occurs when the enzyme-linked antibodies are attached to the antigen, whether antigen is a single protein with multiple epitopes or the surface of a cell with a variety of different antigens. As a result of their juxtaposition, the enzymes produce light only in the presence of the biological material. A brief description is given as to how this assay could be utilized in a personal bio-agent detector system.

    In the present study, the antioxidant activity of successive leaf extracts of Dracaena reflexa was investigated using the scavenging activity on 1,1-diphenyl-2-picrylhydrazyl and reducing power by ferric reducing antioxidant power assay. Methanol extract was found potent in both the assays. IC50 values of 1,1-diphenyl-2-picrylhydrazyl assay for methanol extract was 0.97 mg/ml and ferric reducing antioxidant power value for the same is 1.19. Phytochemical screening, proximate analysis and total phenolic content were also determined. Qualitative screening for phytochemical showed the presence of alkaloids, flavonoids, terpenoids, glycosides and saponins. Highest phenolic content was shown by methanol extract (49.69 mg gallic acid equivalent/g dry weight). Proximate analysis showed moisture content (3.31%), ash content (8.02%), crude fibre (1.31%), crude fat (0.97%), total protein (3.70%), total carbohydrate (86.01) and nutritive value (367.56 kcal/100 g), which would make it a potential nutraceutical. This study suggested that Dracaena reflexa, a potential natural free radical scavenger, which could find use as an antioxidative.

    The occurrence of congenital anomalies in proximity to municipal landfill sites in the Eastern Region (counties Dublin, Kildare, Wicklow) was examined by small area (district electoral division), distance and clustering tendancies in relation to 83 landfills, five of which were major sites. The study included 2136 cases of congenital anomaly, 37,487 births and 1423 controls between 1986 and 1990. For the more populous areas of the region 50% of the population lived within 2-3 km of a landfill and within 4-5 km for more rural areas. In the area-level analysis, the standardised prevalence ratios, empirical and full Bayesian modelling, and Kulldorff\\'s spatial scan statistic found no association between the residential area of cases and location of landfills. In the case control analysis, the mean distance of cases and controls from the nearest landfill was similar. The odds ratios of cases compared to controls for increasing distances from all landfills and major landfills showed no significant difference from the baseline value of 1. The kernel and K methods showed no tendency of cases to cluster in relationship to landfills. In conclusion, congenital anomalies were not found to occur more commonly in proximity to municipal landfills.

    PETS (Proximity Effect Tunneling Spectroscopy) technique has been applied to Niobium/Yttrium and Niobium/Lutetium bilayers. We have determined electron - phonon interaction parameter lambda_{rm e -ph} is 0.55 for Yttrium and 0.67 for Lutetium. Spin fluctuations parameter lambda_{ rm S} is 0.20 for Yttrium and 0.33 for Lutetium. We found that the large spin fluctuations in Yttrium and Lutetium has responsibility to the absence of superconductivity in them. Our results have given a reasonable explanation of high superconducting transition temperature in them under high pressure. The large reflection coefficient and strong diffuse scattering at Nb/Y and Nb/Lu interface has been discovered and it should have strong influence on the transport properties of metallic superlattices. From the modeling study of elastic scattering in proximity effect tunnel junctions, we have explained why some conventional made high {rm T_{C}} superconducting tunnel junctions give ideal like characteristics in the gap region but variable strength phonon structures in the phonon region.

    While cilia are recognized as important signaling organelles, the extent of ciliary functions remains unknown because of difficulties in cataloguing proteins from mammalian primary cilia. We present a method that readily captures rapid snapshots of the ciliary proteome by selectively biotinylating ciliary proteins using a cilia-targeted proximity labeling enzyme (cilia-APEX). Besides identifying known ciliary proteins, cilia-APEX uncovered several ciliary signaling molecules. The kinases PKA, AMPK, and LKB1 were validated as bona fide ciliary proteins and PKA was found to regulate Hedgehog signaling in primary cilia. Furthermore, proteomics profiling of Ift27/Bbs19 mutant cilia correctly detected BBSome accumulation inside Ift27(-/-) cilia and revealed that β-arrestin 2 and the viral receptor CAR are candidate cargoes of the BBSome. This work demonstrates that proximity labeling can be applied to proteomics of non-membrane-enclosed organelles and suggests that proteomics profiling of cilia will enable a rapid and powerful characterization of ciliopathies.

  20. Empathy: Its ultimate and proximate bases.

    There is disagreement in the literature about the exact nature of the phenomenon of empathy. There are emotional, cognitive, and conditioning views, applying in varying degrees across species. An adequate description of the ultimate and proximate mechanism can integrate these views. Proximately, the perception of an object's state activates the subject's corresponding representations, which in turn activate somatic and autonomic responses. This mechanism supports basic behaviors (e.g., alarm, social facilitation, vicariousness of emotions, mother-infant responsiveness, and the modeling of competitors and predators) that are crucial for the reproductive success of animals living in groups. The Perception-Action Model (PAM), together with an understanding of how representations change with experience, can explain the major empirical effects in the literature (similarity, familiarity, past experience, explicit teaching, and salience). It can also predict a variety of empathy disorders. The interaction between the PAM and prefrontal functioning can also explain different levels of empathy across species and age groups. This view can advance our evolutionary understanding of empathy beyond inclusive fitness and reciprocal altruism and can explain different levels of empathy across individuals, species, stages of development, and situations.

    The purpose of this study was to examine the results of the proximal femoral osteotomy for the management of hip deformity in 32 children, aged 4 to 15 years. Twenty-two bilateral and ten unilateral procedures were performed. The indications for surgery were subluxation in 16, dislocation in two, and intoeing and femoral anteversion in 14. The average follow-up was two years and 11 months. CE angle of Wiberg, acetabular index and neck shaft angle were evaluated. The average time to regain preoperative ambulatory status was six months with intensive physical therapy. In osteotomies performed for subluxation, dislocation did not occur; roentgenographic indices showed variability in the degree of subluxation. Osteotomy performed in children older than 8 years of age produced no evidence of acetabular remodeling. THere was no recurrence with osteotomies for dislocation. In those patients with internal rotation gait, improvement resulted. Complications were few and minor. Hip dislocation in children with progressive subluxation, in spite of previous soft-tissue releases, is preventable by proximal femoral osteotomy. The inability of the roentgenographic indices to quantitate the increased stability indicates the procedure's major effect is to realign muscle forces about the hip. Treatment of the intoeing gait produced improvement of rotational deformity.

    We examined whether physical proximity to supermarkets or supermarket price was more strongly associated with obesity risk. The Seattle Obesity Study (SOS) collected and geocoded data on home addresses and food shopping destinations for a representative sample of adult residents of King County, Washington. Supermarkets were stratified into 3 price levels based on average cost of the market basket. Sociodemographic and health data were obtained from a telephone survey. Modified Poisson regression was used to test the associations between obesity and supermarket variables. Only 1 in 7 respondents reported shopping at the nearest supermarket. The risk of obesity was not associated with street network distances between home and the nearest supermarket or the supermarket that SOS participants reported as their primary food source. The type of supermarket, by price, was found to be inversely and significantly associated with obesity rates, even after adjusting for individual-level sociodemographic and lifestyle variables, and proximity measures (adjusted relative risk=0.34; 95% confidence interval=0.19, 0.63) Improving physical access to supermarkets may be one strategy to deal with the obesity epidemic; improving economic access to healthy foods is another.

    Automated spacecraft docking operations are being performed using a full scale motion based simulator and an optical sensor. This presentation will discuss the work in progress at TRW and MSFC facilities to study the problem of automated proximity and docking operations. The docking sensor used in the MSFC Optical Sensor and simulation runs are performed using the MSFC Flat Floor Facility. The control algorithms and six degrees of freedom (6DOF) simulation software were developed at TRW and integrated into the MSFC facility. Key issues being studied are the quantification of docking sensor requirements and operational constraints necessary to perform automated docking maneuvers, control algorithms capable of performing automated docking in the presence of sensitive and noisy sensor data, and sensor technologies for automated proximity and docking operations. As part of this study the MSFC sensor characteristics were analyzed and modeled so that off line simulation runs can be performed for control algorithm testing. Our goal is to develop and demonstrate full 6DOF docking capabilities with actual sensors on the MSFC motion based simulator. We present findings from actual docking simulation runs which show sensor and control loop performance as well as problem areas which require close attention. The evolution of various control algorithms using both phase plane and Clohessy-Wiltshire techniques are discussed. In addition, 6DOF target acquisition and control strategies are described.

    Methicillin-resistant Staphylococcus aureus (MRSA) infection and colonization, involving MRSA strains which differ from common human health care-associated clones, have become serious emerging conditions in equine veterinary hospitals. In 2010, MRSA spa type t535 caused an outbreak involving both horses and personnel in a veterinary teaching hospital in Israel. Since then, surveillance continued, and occasional MRSA isolation occurred. Two years later, MRSA of another spa type, t002, was isolated from a veterinarian and, 3 weeks later, from a horse. The appearance of spa type t002, a common clone in human medicine in Israel, among both personnel and horses, prompted a point-prevalence survey of hospital personnel and hospitalized horses. Fifty-nine staff members (n = 16 equine; n = 43, other) and 14 horses were screened. Ten of 59 staff members (16.9%) and 7 of 14 horses (50%) were MRSA carriers. Among the staff, 44% of large animal department (LAD) personnel, compared with only 7% of non-LAD personnel, were carriers. Isolates from all horses and from 9 of 10 personnel were found to be of MRSA spa type t002. This clone was later isolated from an infected postoperative wound in a hospitalized horse. Measures were taken to contain transmission between horses and personnel, as was done in the previous outbreak, resulting in reduction of transmission and, finally, cessation of cross-transmission between horses and personnel.

    Methicillin-resistant Staphylococcus aureus (MRSA) has been one of the most important antibiotic-resistant pathogen in many parts of the world over the past decades. This cross-sectional study was conducted to investigate MRSA isolated between July 2013 and July 2014 in Karaj, Iran. All tested isolates were collected in teaching hospitals from personnel, patients, and surfaces and each MRSA was analyzed by SCCmec and spa typing. Antibiotic susceptibility testing was accomplished by disk diffusion method. Out of 49 MRSA isolates from the Karaj's teaching hospitals, 82%, 10%, and 6% of the isolates were SCCmec types III, II, and I, respectively. The main spa type in this study was spa t030 with frequency as high as 75.5% from intensive care unit (ICU) of the hospitals and high rate of resistance to rifampicin (53%) was found in MRSA isolates. In conclusion, high frequency of spa t030 with SCCmec type III and MRSA phenotype illustrated circulating of one of the antibiotic-resistant strains in ICU of Karaj's teaching hospitals and emphasizes the need for ongoing molecular surveillance, antibiotic susceptibility monitoring, and infection control.

    Spread of methicillin-resistant Staphylococcus aureus (MRSA) isolates is a worldwide problem. Molecular typing is a useful tool to understand MRSA epidemiology. Herein, we determined vancomycin-resistant, SCCmec and spa types among MRSA isolates recovered from healthcare and community-acquired infections in Kerman, Iran. A total of 170 S. aureus isolates were collected from different patients who were admitted to affiliated hospitals of Kerman University of Medical science. MRSA and vancomycin-resistant S. aureus (VRSA) isolates were detected by phenotypic methods. Polymerase chain reaction (PCR) technique was used for detection of mecA, vanA and vanB genes. Staphylococcal cassette chromosomemec (SCCmec) and spa typing were used for molecular typing of among MRSA isolates. Overall, 53% of isolates were considered as MRSA. Two MRSA isolates were resistant to vancomycin and vanA was detected in only one of VRSA isolates. SCCmec type III belonged to spa types t030 and t459 which they were the dominant spa types among community-associated MRSA (CA-MRSA) and healthcare-acquired MRSA (HA-MRSA) isolates. Our findings showed that the SCCmec type I and III spread from hospital settings to community, although the SCCmec type IV spread from community to healthcare systems. We have also reported VRSA isolates from hospitalized patients, therefore, appropriate policies should be enforced in order to prevent the spread of antibiotic resistance isolates in hospitals settings.

    The interior of SPA contains a range of morphologic units, from smooth plains and mare basalts to rough, ancient, terrains. Recent data, particularly from LRO provide unique measures of SPA surface properties. With each new dataset, the differences between the interior of SPA and its surroundings become more, or in some cases less, clearly defined. Here we explore recent datasets that offer insight into surface roughness at a variety of scales and assess implications for the origins of units across SPA. Identifying the origin of units in SPA is critical for identifying future sampling sites that address the science goal of determining the age of SPA. The unique interior of SPA relative to the rest of the Moon is demonstrated by Mini-RF and LOLA derived products. Mini-RF data shows that the interior of SPA has a slightly higher average Circular Polarization Ratio than nearly any other terrain on the Moon, with the exception of the interior of the Orientale Basin. Cahill et al. [2014,Icarus] note that the average interior CPR value of SPA is similar but slightly higher than the mid-latitude farside highlands, suggesting that both are enhanced in blocks at the surface and near subsurface (to depths SPA is distinct relative to the interior of Orientale in the m-chi deconvolution, suggesting that the interior has a regolith with scatterers smaller than the wavelength of Mini-RF (12.6cm). LOLA-derived roughness shows that the interior of SPA is smoother than the surrounding highlands [Rosenburg et al.,2011,JGR; Kreslavsky et al., 2013,Icarus]. LOLA roughness measures show roughness variations within the basin tied to volcanism. However the expanse of smooth areas is broader than the previously mapped volcanic units, suggesting that ancient volcanism may be contributing to interior smoothness. The distinction between datasets is likely due to differences in spatial resolution and that Mini-RF data probes the near subsurface. These measurements of roughness offer insight

    Bone loss secondary to primary or metastatic lesions of the proximal humerus remains a challenging surgical problem. Options include preservation of the joint with stabilisation using internal fixation or resection of the tumour with prosthetic replacement. Resection of the proximal humerus often includes the greater tuberosity and adjacent diaphysis, which may result in poor function secondary to loss of the rotator cuff and/or deltoid function. Preservation of the joint with internal fixation may reduce the time in hospital and peri-operative morbidity compared with joint replacement, and result in a better functional outcome. We included 32 patients with pathological fractures of the proximal humerus in this study. Functional and radiological assessments were performed. At a mean follow-up of 17.6 months (8 to 61) there was no radiological evidence of failure of fixation. The mean revised musculoskeletal Tumour Society functional score was 94.6% (86% to 99%). There was recurrent tumour requiring further surgery in four patients (12.5%). Of the 22 patients who were employed prior to presentation all returned to work without restrictions. The use of a locking plate combined with augmentation with cement extends the indications for salvage of the proximal humerus with good function in patients with pathological and impending pathological fractures.

    To evaluate the diagnostic accuracy of proximal caries detection from digitized film images captured by a digital camera at different resolution settings. Twenty-five periapical radiographs of 50 premolar and 25 molar teeth were photographed using a digital camera, Sony Cyber-shot, DSC-S75 at three different resolution settings: 640 x 480, 1280 x 960 and 1600 x 1200. Seventy-five digital images were transferred to a computer, saved and opened using ACDSee software. In addition, a PowerPoint slide was made from each digital image. Five observers scored three groups of images (the films, the displayed 1:1 digital images on the ACDSee software, and the PowerPoint slides) for the existence of proximal caries using a 5-point confidence scale, and the depth of caries on a 4-point scale. Ground sections of the teeth were used as the gold standard. Az values under the receiver operating characteristic (ROC) curve of each group of images and at different resolutions were compared using the Friedman and Wilcoxon signed rank tests. Mean different values between the lesions' depth interpreted by the observers and that of the gold standard were analysed. Films showed the highest Az values. Only the 1280 x 960 images on the ACDSee software showed no significant difference of the Az value from the films (P=0.28). The digital images from three resolution settings on the PowerPoint slides showed no significant differences, either among each other or between them and the films. For caries depth, the 1280 x 960 images showed lower values of mean difference in enamel lesions compared with the other two resolution groups. This study showed that in order to digitize conventional films, it was not necessary to use the highest camera resolution setting to achieve high diagnostic accuracy for proximal caries detection. The 1280 x 960 resolution setting of the digital camera demonstrated comparable diagnostic accuracy with film and was adequate for digitizing radiographs for caries

    Legionnaires' disease can result when droplets or aerosols containing legionella bacteria are inhaled and deposited in the lungs. A number of outbreaks have been associated with the use of a spa pool where aeration, a high water temperature, and a large and variable organic load make disinfectant levels difficult to maintain. Spa pool ownership is increasing, and the aim of this study, using two surrogate organisms (MS-2 coliphage and Pseudomonas aeruginosa [a natural contaminant]), was to assess the potential risk to domestic users when disinfection fails. A representative "entry level" domestic spa pool was installed in an outdoor courtyard. The manufacturer's instructions for spa pool maintenance were not followed. A cyclone sampler was used to sample the aerosols released from the spa pool with and without activation of the air injection system. Samples were taken at increasing heights and distances from the pool. An aerodynamic particle sizer was used to measure the water droplet size distribution at each sample point. When the air injection system was inactivated, neither surrogate organism was recovered from the air. On activation of the air injection system, the mean mass of droplets within the respirable range (10 cm above the water line) was 36.8 μg cm(-3). This corresponded to a mean air concentration of P. aeruginosa of 350 CFU m(-3). From extrapolation from animal data, the estimated risk of infection from aerosols contaminated with similar concentrations of Legionella pneumophila was 0.76 (males) and 0.65 (females). At 1 m above and/or beyond the pool, the mean aerosol mass decreased to 0.04 μg cm(-3) and corresponded to a 100-fold reduction in mean microbial air concentration. The estimated risk of infection at this distance was negligible. Copyright © 2015, American Society for Microbiology. All Rights Reserved.

    The present study was undertaken to type Staphylococcus aureus isolates from cattle and buffalo mastitic milk on the basis of spa (X-region) and clfA genes, both responsible for producing virulence factors. In the present investigation S. aureus isolates were isolated as per standard protocols. Typing of S. aureus was carried out by molecular detection of spa and clfA gene by polymerase chain reaction. All the 32 isolates from cattle (16) and buffalo (16) were divisible into seven spa types with amplicon sizes ranging between 120 and 380bp. The cattle isolates produced seven different spa amplicons of 120, 150, 200, 250, 280, 300, and 330 bp with 3, 4, 6, 8, 10, 11 and 12 number of tandem repeats, respectively whereas buffalo isolates were divisible into five spa types with amplicons of 150, 200, 250, 330 and 380 bp having calculated number of repeats of 5, 7, 9, 12, and 14, respectively. Of the total isolates, 24 were considered pathogenic on the basis of more than seven number of tandem repeats. In the present investigation, clfA gene was amplified in 27 isolates from cattle and buffalo producing two different amplicons of 900 and 1000 bp sizes showing polymorphism. The most (71.80%) of the isolates produced amplicons of 900 bp while amplicon size of 1000 bp was produced by four (12.5%) of the isolates. The presence of these genes with a wide degree of polymorphism confirmed the pathogenic potential of S. aureus and their association with clinical manifestations in mastitis among cattle and buffalo.
