Effects of Test Conditions on APA Rutting and Prediction Modeling for Asphalt Mixtures

Directory of Open Access Journals (Sweden)

Hui Wang

2017-01-01

Full Text Available APA rutting tests were conducted for six kinds of asphalt mixtures under air-dry and immersing conditions. The influences of test conditions, including load, temperature, air voids, and moisture, on APA rutting depth were analyzed by using grey correlation method, and the APA rutting depth prediction model was established. Results show that the modified asphalt mixtures have bigger rutting depth ratios of air-dry to immersing conditions, indicating that the modified asphalt mixtures have better antirutting properties and water stability than the matrix asphalt mixtures. The grey correlation degrees of temperature, load, air void, and immersing conditions on APA rutting depth decrease successively, which means that temperature is the most significant influencing factor. The proposed indoor APA rutting prediction model has good prediction accuracy, and the correlation coefficient between the predicted and the measured rutting depths is 96.3%.

Molecular Regulation of Alternative Polyadenylation (APA) within the Drosophila Nervous System.

Science.gov (United States)

Vallejos Baier, Raul; Picao-Osorio, Joao; Alonso, Claudio R

2017-10-27

Alternative polyadenylation (APA) is a widespread gene regulatory mechanism that generates mRNAs with different 3'-ends, allowing them to interact with different sets of RNA regulators such as microRNAs and RNA-binding proteins. Recent studies have shown that during development, neural tissues produce mRNAs with particularly long 3'UTRs, suggesting that such extensions might be important for neural development and function. Despite this, the mechanisms underlying neural APA are not well understood. Here, we investigate this problem within the Drosophila nervous system, focusing on the roles played by general cleavage and polyadenylation factors (CPA factors). In particular, we examine the model that modulations in CPA factor concentration may affect APA during development. For this, we first analyse the expression of the Drosophila orthologues of all mammalian CPA factors and note that their expression decreases during embryogenesis. In contrast to this global developmental decrease in CPA factor expression, we see that cleavage factor I (CFI) expression is actually elevated in the late embryonic central nervous system, suggesting that CFI might play a special role in neural tissues. To test this, we use the UAS/Gal4 system to deplete CFI proteins from neural tissue and observe that in this condition, multiple genes switch their APA patterns, demonstrating a role of CFI in APA control during Drosophila neural development. Furthermore, analysis of genes with 3'UTR extensions of different length leads us to suggest a novel relation between 3'UTR length and sensitivity to CPA factor expression. Our work thus contributes to the understanding of the mechanisms of APA control within the developing central nervous system. Copyright © 2017 The Authors. Published by Elsevier Ltd..

2001-01-01

In the frame of the studies required by the French law of 1991, CEA have launched a wide range of assessments on waste management for different reactors (PWR, FBR). Considerable R and D work has already been performed in order to improve the use of Plutonium (Pu) in PWRs. In this context, the Advanced Plutonium Assembly (APA) aims to improve the use of Plutonium (Pu) in PWRs while minimizing Minor Actinides (MA) production, with only slight modifications of the core design. From a neutronic point of view, the overall studied cases lead to the stabilization of the Pu inventory with approximately 30% of the park refueled with APA assemblies in full APA cores. Multi-recycling could satisfy the stabilization of Pu+ (Am+Cm) inventory by the implementation of approximately 40% APA reactors in a conventional PWRs park. After 7 or 8 recycles, the equilibrium is reached. The Pu inventory in the fuel cycle ranges from 210 tons to 270 tons for Pu multi-recycling, and from 240 tons to 290 tons for Pu+(Am+Cm) multi-recycling. The saving in Natural Uranium and Separative Work Units (SWU) due to the use of APA reactors would be between 30% and 15% in comparison with the UO 2 open cycle. This paper presents a selection of the main preliminary Pu recycling results of the joint study program COGEMA-CEA. (author)

Oral administration of microcapsules containing live bacterial cells has potential as an alternative therapy for several diseases. This article evaluates the suitability of the alginate-poly-L-lysine-alginate (APA) microcapsules for oral delivery of live bacterial cells, in-vitro, using a dynamic simulated human gastro-intestinal (GI) model. Results showed that the APA microcapsules were morphologically stable in the simulated stomach conditions, but did not retain their structural integrity after a 3-day exposure in simulated human GI media. The microbial populations of the tested bacterial cells and the activities of the tested enzymes in the simulated human GI suspension were not substantially altered by the presence of the APA microcapsules, suggesting that there were no significant adverse effects of oral administration of the APA microcapsules on the flora of the human gastrointestinal tract. When the APA microcapsules containing Lactobacillus plantarum 80 (LP80) were challenged in the simulated gastric medium (pH = 2.0), 80.0% of the encapsulated cells remained viable after a 5-min incubation; however, the viability decreased considerably (8.3%) after 15 min and dropped to 2.6% after 30 min and lower than 0.2% after 60 min, indicating the limitations of the currently obtainable APA membrane for oral delivery of live bacteria. Further in-vivo studies are required before conclusions can be made concerning the inadequacy of APA microcapsules for oral delivery of live bacterial cells.

Family physicians have a key role in the promotion of physical activity, in particular in identifying and counseling persons who have a sedentary lifestyle. Some patients could benefit from intensive individual counseling. Physicians are often not aware of all physical activity promotion activities in the community that they could recommend their patients. In a pilot study, we have tested and adapted the referral of patients from family physicians to specialists in adapted physical activity (APAs). APAs are trained to assess and guide persons towards physical activities adapted to their needs and pathologies and thus towards an increase in physical activity. Pilot data suggest that, while few patients were oriented to the APAs in the pilot project, family physicians appreciate the possibility of collaborating with the APAs.

Actinobacillus pleuropneumoniae is the causative agent of porcine pleuropneumonia, and adherence to host cells is a key step in the pathogenic process. Although trimeric autotransporter adhesins (TAAs) were identified in many pathogenic bacteria in recent years, none in A. pleuropneumoniae have been characterized. In this study, we identified a TAA from A. pleuropneumoniae, Apa, and characterized the contribution of its amino acid residues to the adhesion process. Sequence analysis of the C-terminal amino acid residues of Apa revealed the presence of a putative translocator domain and six conserved HsfBD1-like or HsfBD2-like binding domains. Western blot analysis revealed that the 126 C-terminal amino acids of Apa could form trimeric molecules. By confocal laser scanning microscopy, one of these six domains (ApaBD3) was determined to mediate adherence to epithelial cells. Adherence assays and adherence inhibition assays using a recombinant E. coli- ApaBD3 strain which expressed ApaBD3 on the surface of E. coli confirmed that this domain was responsible for the adhesion activity. Moreover, cellular enzyme-linked immunosorbent assays demonstrated that ApaBD3 mediated high-level adherence to epithelial cell lines. Intriguingly, autoagglutination was observed with the E. coli- ApaBD3 strain, and this phenomenon was dependent upon the association of the expressed ApaBD3 with the C-terminal translocator domain.

2010-04-29

An interesting seed protein family with a role in preventing insect herbivory is the multi-gene, APA family encoding the alpha-amylase inhibitor, phytohemagglutinin and arcelin proteins of common bean (Phaseolus vulgaris). Variability for this gene family exists and has been exploited to breed for insect resistance. For example, the arcelin locus has been successfully transferred from wild to cultivated common bean genotypes to provide resistance against the bruchid species Zabrotes subfasciatus although the process has been hampered by a lack of genetic tools for and understanding about the locus. In this study, we analyzed linkage disequilibrium (LD) between microsatellite markers at the APA locus and bruchid resistance in a germplasm survey of 105 resistant and susceptible genotypes and compared this with LD in other parts of the genome. Microsatellite allele diversity was found to vary with each of the eight APA-linked markers analyzed, and two markers within the APA locus were found to be diagnostic for bruchid resistance or susceptibility and for the different arcelin alleles inherited from the wild accessions. Arc1 was found to provide higher levels of resistance than Arc5 and the markers in the APA locus were highly associated with resistance showing that introgression of this gene-family from wild beans provides resistance in cultivated beans. LD around the APA locus was found to be intermediate compared to other regions of the genome and the highest LD was found within the APA locus itself for example between the markers PV-atct001 and PV-ag004. We found the APA locus to be an important genetic determinant of bruchid resistance and also found that LD existed mostly within the APA locus but not beyond it. Moderate LD was also found for some other regions of the genome perhaps related to domestication genes. The LD pattern may reflect the introgression of arcelin from the wild into the cultivated background through breeding. LD and association studies for

To explore the changes of alginate-polylysine-alginate microcapsulated bovine adrenal medullary chromaffin cells (APA-BCC microcapsules) in morphology, survival rate and leucine- enkephalin secretion after they were transplanted into CSF of cancerpain patients, the APA- BCC microcapsules were Implanted into cavitas subarachnoidealis of cancer-pain patients by conventional lumbar puncture. After 7 or 8 days, cerebrospinal fluid was collected and the morphology of the APA-BCC microcapsule, the survival rate of cells were observed and secretory volume of leucine-enkephalin was assayed by radioimmunity method. Seven days after trans- plantation, the mean VAS decreased from 8.8 to 2.4, the survival rate of cells averagely reduced from 91.2% to 89.1%, morphology of APA-BCC microcapsules did not change obviously and secretory volume of leucine-enkephalin went up 1.65 times compared with that at pretrans- plantation. In conclusion, APA-BCC can survive, secret leucine-enkephalin and produce analgesic effect after transplanted into CSF of cancer-patients. (authors)

The Neuro-Mechanical Processes That Underlie Goal-Directed Medio-Lateral APA during Gait Initiation.

Science.gov (United States)

Honeine, Jean-Louis; Schieppati, Marco; Crisafulli, Oscar; Do, Manh-Cuong

2016-01-01

Gait initiation (GI) involves passing from bipedal to unipedal stance. It requires a rapid movement of the center of foot pressure (CoP) towards the future swing foot and of the center of mass (CoM) in the direction of the stance foot prior to the incoming step. This anticipatory postural adjustment (APA) allows disengaging the swing leg from the ground and establishing favorable conditions for stepping. This study aimed to describe the neuro-mechanical process that underlies the goal-directed medio-lateral (ML) APA. We hypothesized that controlled knee flexion of the stance leg contributes to the initial ML displacement of the CoP and to the calibration of the first step. Fourteen subjects initiated gait starting from three different initial stance widths of 15 cm (Small), 30 cm (Medium), and 45 cm (Large). Optoelectronic, force platform and electromyogram (EMG) measurements were performed. During APA, soleus activity diminished bilaterally, while tibialis anterior (TA) activity increased, more so in the stance leg than in the swing leg, and to a larger extent with increasing initial stance width. Knee flexion of the stance leg was observed during APA and correlated with the ML CoP displacement towards the swing leg. ML CoP and CoM displacements during APA increased with increasing stance width. The activity of stance-leg TA was correlated with the degree of knee flexion. Swing-leg tensor fasciae latae (TFL) was also active during APA. Across subjects, when stance-leg tibialis activity was low, TFL activity was large and vice versa. The modulation of the ML CoP position during APA allowed the gravity-driven torque to place the CoM just lateral to the stance foot during step execution. Accordingly, the gravity-driven torque, the ML CoM velocity during step execution, and the step width at foot contact (FC) were lower in the Small and greater in the Large condition. Consequently, the position of the stepping foot at FC remained close to the sagittal plane in all

Salerno, Marco; Giacomelli, Luca; Larosa, Claudio

2011-01-06

Examples of programmed tissue response after the interaction of cells with biomaterials are a hot topic in current dental research. We propose here the use of anodic porous alumina (APA) for the programming of cell growth in oral tissues. In particular, APA may trigger cell growth by the controlled release of specific growth factors and/or ions. Moreover, APA may be used as a scaffold to promote generation of new tissue, due to the high interconnectivity of pores and the high surface roughness displayed by this material.

2005-01-01

For optimization of preparation condition, simplification of technique and quality control, we observed partial physical and chemical factors in process of preparation of alginate-polylysine-alginate (APA) microcapsular immune isolation biomembrane. The result showed that granular diameter of the microcapsules was negatively correlated with pulse frequency of static microcapsule generator and positively correlated with speed of driving pump and bore of pinhead. The membrane thickness was remarkably increased with the increase of polylysine density. Prolonging reaction time of shaping membrane didn't change granular diameter of the microcapsules, but influenced membrane thickness. Liquefaction time of sodium citrate had no remarkable effect on granular diameter and membrane thickness. APA microcapsular immuno isolation biomembrane would have better permeability, flexibility, biological compatibility and intensity by optimizing preparation conditions. (authors)

2012-11-01

Presents a short biography of the winner of the American Psychological Association's Psi Chi/APA Edwin B. Newman Graduate Research Award. The 2012 winner is Cynthia J. Najdowski for an outstanding research paper that examines how jurors' judgments are influenced by a juvenile defendant's confession and status as intellectually disabled. Through the use of a mock trial experiment, the research revealed that jurors discounted a juvenile's coerced confession and sometimes used intellectual disability as a mitigating factor. Attribution theory and the discounting principle were used to identify the psychological mechanisms underlying this effect. The paper, titled 'Understanding Jurors' Judgments in Cases Involving Juvenile Defendants,' was published in Psychology, Public Policy, and Law in October 2011 and was the basis for Najdowski's selection as the recipient of the 2012 Psi Chi/APA Edwin B. Newman Graduate Research Award. Bette L. Bottoms, PhD, served as faculty supervisor. Najdowski's Award citation and a selected bibliography are also presented.

Cationic surfactant is a chemical substance used in hair conditioner, fabric softener and other household products. By investigating the relationship between the aquatic toxicity and the chemical structures of two types of mono alkyl cationic surfactants, alkyl trimethylammonium salts and alkyl dimethylamine salts, we have found that the C22 alkyl chain length is effective to reduce the toxicity. Besides, we have recognized that the amidopropyl functional group contributes to the enhanced biodegradability by investigating the biodegradation trend of (alkylamidopropyl)dimethylamine salt (alkyl chain length: C18). Based on these findings, we have developed mono alkyl cationic surfactant called APA-22, N-[3-(dimethylamino)propyl]docosanamide salt. APA-22 is formed by the C22 alkyl chain, amidopropyl functional group and di-methyltertiary amine group. We evaluated the aerobic and anaerobic biodegradability of APA-22 by two standard methods (OECD Test Guideline 301B and ECETOC technical document No.28) and found that this substance was degraded rapidly in both conditions. The toxicity to algae, invertebrate and fish of this substance are evaluated by using OECD Test Guideline 201, 202 and 203, respectively. All acute toxicity values are >1 mg/L, which indicates that environmental toxicity of this substance is relatively less toxic to aquatic organism. In addition, we estimated the biodegradation pathway of APA-22 and observed the complete disappearance of APA-22 and its intermediates during the test periods. Based on the environmental data provided above, we concluded that APA22 is more compatible with the aquatic environment compared to other cationic surfactants with mono long alkyl chain.

2018-01-01

Following a review of extant reporting standards for scientific publication, and reviewing 10 years of experience since publication of the first set of reporting standards by the American Psychological Association (APA; APA Publications and Communications Board Working Group on Journal Article Reporting Standards, 2008), the APA Working Group on Quantitative Research Reporting Standards recommended some modifications to the original standards. Examples of modifications include division of hypotheses, analyses, and conclusions into 3 groupings (primary, secondary, and exploratory) and some changes to the section on meta-analysis. Several new modules are included that report standards for observational studies, clinical trials, longitudinal studies, replication studies, and N-of-1 studies. In addition, standards for analytic methods with unique characteristics and output (structural equation modeling and Bayesian analysis) are included. These proposals were accepted by the Publications and Communications Board of APA and supersede the standards included in the 6th edition of the Publication Manual of the American Psychological Association (APA, 2010).

Selling violent video game solutions: A look inside the APA's internal notes leading to the creation of the APA's 2005 resolution on violence in video games and interactive media.

Science.gov (United States)

Copenhaver, Allen; Ferguson, Christopher J

For decades politicians, parent groups, researchers, media outlets, professionals in various fields, and laymen have debated the effects playing violent video games have on children and adolescents. In academia, there also exists a divide as to whether violent video games cause children and adolescents to be aggressive, violent, and even engage in criminal behavior. Given inconsistencies in the data, it may be important to understand the ways and the reasons why professional organizations take a stance on the violent video game effects debate which may reflect greater expressed certitude than data can support. This piece focuses on the American Psychological Association's internal communications leading to the creation of their 2005 Resolution on Violence in Video Games and Interactive Media. These communications reveal that in this case, the APA attempted to "sell" itself as a solution to the perceived violent video game problem. The actions leading to the 2005 resolution are then compared to the actions of the APA's 2013-2015 Task Force on Violent Media. The implications and problems associated with the APA's actions regarding violent video games are addressed and discussed below. Copyright © 2018 Elsevier Ltd. All rights reserved.

A new linker cis-5-aminopent-3-enoic acid (cis-Apa) was prepared for the synthesis of cyclic pseudopeptides by cyclization-cleavage by using ring-closing methatesis (RCM). We developed a new synthetic pathway for the preparation of the cis-Apa linker that was tested in the cyclization-cleavage process of different RGD peptide sequences. Different macrocyclic peptidomimetics were prepared by using this integrated microwave-assisted method, showing that the readily available cis-Apa amino acid is well adapted as a linker in the cyclization-cleavage process.

The repairing of large segmental bone defects is difficult for clinical orthopedists at present. Gene therapy is regarded as a promising method for bone defects repair. The present study aimed to construct an effective and controllable Tet-On expression system for transferring hBMP-2 gene into bone marrow mesenchymal progenitor cells (BMSCs). Meanwhile, with combination of alginate-poly-L-lysine-alginate (APA) microencapsulation technology, we attempted to reduce the influence of immunologic rejection and examine the effect of the Tet-On expression system on osteogenesis of BMSCs. The adenovirus encoding hBMP-2 (ADV-hBMP2) was constructed using the means of molecular cloning. The ADV-hBMP2 and Adeno-X Tet-On virus was respectively transfected to the HEK293 for amplification and afterward BMSCs were co-infected with the virus of ADV-hBMP2 and the Adeno-X Tet-On. The expression of hBMP-2 was measured with induction by doxycycline (DOX) at different concentration by means of RT-PCR and ELISA. Combining Tet-On expression system and APA microcapsules with the use of the pulsed high-voltage electrostatic microcapsule instrument, we examined the expression level of hBMP-2 in APA microcapsules by ELISA as well as the osteogenesis by alizarin red S staining. An effective Tet-On expression system for transferring hBMP-2 gene into BMSCs was constructed successfully. Also, the expression of hBMP-2 could be regulated by concentration of DOX. The data exhibited that BMSCs in APA microcapsules maintained the capability of proliferation and differentiation. The combination of Tet-On expression system and APA microcapsules could promote the osteogenesis of BMSCs. According to the results, microencapsulated Tet-On expression system showed the effective characteristics of secreting hBMP-2 and enhancing osteogenesis, which would provide a promising way for bone repair.

Silkworm pupae oil derived from reeling waste is a rich source of α-linolenic acid (ALA), which has multipal applications. ALAs were added in sn-1, 3 positions in a triacylglycerol (TAG) to produce an APA-human milk fat analogues (APA-HMFAs, A: α-linolenic acid, P: palmitic acid). The optimum condition is that tripalmitin to free fatty acids of 1:12 (mole ratio) at 65 °C for 48 h using lipase Lipozyme RM IM. Results show that, the major TAG species that comprised APA-HMFAs were rich in ALA and palmitic acid, which contained 64.52% total unsaturated fatty acids (UFAs) and 97.05% PA at the sn-2 position. The melting point of APA was -27.5 °C which is much lower than tripalmitin (40.5 °C) indicating more plastic character. In addition, the practical application of alkyl caffeates as liposoluble antioxidants in APA was developed. Alkyl caffeate showed a superior IC50 (1.25-1.66 μg/mL) compared to butyl hydroxy anisd (1.67 μg/mL) and L-ascorbic acid-6-palmitate (L-AP) (1.87 μg/mL) in DPPH analysis. The addition of ethyl caffeate to oil achieved a higher UFAs content (73.58%) at high temperatures. Overall, APA was obtained from silkworm pupae oil successfully, and the addition of caffeates extended storage ranges for APA-HMFAs.

Johne's disease or paratuberculosis is widespread in almost all countries and remains difficult to eradicate. Nowadays, diagnosis of Mycobacterium avium subsp. paratuberculosis (MPTB) infection is one of the main concerns. In this work, we evaluated the expression, biochemical properties and antigenicity of the Apa antigen, encoded by the gene annotated as MAP1569, in the MPTB genome. We confirmed its expression in MPTB and its glycosylation by the ConA binding assay. Although the MPTB-Apa is not an immunodominant antigen, MPTB-infected cattle showed a strong humoral response to recombinant Apa by Western blot and ELISA. Milk was also a suitable sample to be tested by ELISA. We comparatively analysed the humoral cross-reactivity to the Apa from MPTB (MPTB-Apa) and the orthologue from Mycobacterium tuberculosis (MT-Apa, identical to that from Mycobacterium bovis) in both infected and control cows. Response of M. bovis- and MPTB-infected animals against MT-Apa was similar (P=0.6985) but the response of the M. bovis-infected ones to MPTB-Apa was differential, being significantly diminished (PApa stimulation in the IFNgamma release assay, we found no significant differences when compared infected herds with non-infected ones (P=0.34). This antigen, in contrast to bovine Purified Protein Derivative (PPDb), was strongly represented in avian PPD (PPDa), as shown by the recognition of BALB/c mice hyperimmune sera against MPTB-Apa by Dot-blot immunoassay. We therefore demonstrated the antigenicity of Apa in MPTB-infected animals and a differential response to the recombinant antigen when compared to M. bovis-infected animals. These traits herein described, added to the usefulness of milk samples to detect IgG anti-Apa, could be important for routine screening in dairy cattle, considering a multiantigenic approach to overcome the lack of immunodominance.

In order to investigate the encapsulation of interleukin 1 receptor antagonist (IL-RA) gene-modified mesenchymal stem cells (MSCs) in alginate-poly-L-lysine (APA) microcapsules for the persistent delivery of interleukin 1 receptor antagonist (IL-RA) to treat Rheumatoid arthritis (RA). We transfect mesenchymal stem cells with IL-RA gene, and quantify the IL-RA proteins released from the encapsulated cells followed by microencapsulation of recombinant mesenchymal stem cells, and thus observe the permeability of APA microcapsules and evaluate clinical effects after induction and treatment of collagen-induced arthritis (CIA). The concentration of IL-RA in the supernatant was determined by IL-RA ELISA kit by run in technical triplicates using samples from three separate mice. Encapsulated IL-RA gene-transfected cells were capable of constitutive delivery of IL-RA proteins for at least 30 days. Moreover, the APA microcapsules could inhibit the permeation of fluorescein isothiocyanate-conjuncted immunoglobulin G. Also, it has been found that the APA microcapsules can significantly attenuate collagen induced arthritis after delivering of APA microcapsules to rats. Our results demonstrated that the nonautologous IL-RA gene-transfected stem cells are of potential utility for RA therapy.

There have been substantial improvements in the management of acute pancreatitis since the publication of the International Association of Pancreatology (IAP) treatment guidelines in 2002. A collaboration of the IAP and the American Pancreatic Association (APA) was undertaken to revise these guidelines using an evidence-based approach. Twelve multidisciplinary review groups performed systematic literature reviews to answer 38 predefined clinical questions. Recommendations were graded using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. The review groups presented their recommendations during the 2012 joint IAP/APA meeting. At this one-day, interactive conference, relevant remarks were voiced and overall agreement on each recommendation was quantified using plenary voting. The 38 recommendations covered 12 topics related to the clinical management of acute pancreatitis: A) diagnosis of acute pancreatitis and etiology, B) prognostication/predicting severity, C) imaging, D) fluid therapy, E) intensive care management, F) preventing infectious complications, G) nutritional support, H) biliary tract management, I) indications for intervention in necrotizing pancreatitis, J) timing of intervention in necrotizing pancreatitis, K) intervention strategies in necrotizing pancreatitis, and L) timing of cholecystectomy. Using the GRADE system, 21 of the 38 (55%) recommendations, were rated as 'strong' and plenary voting revealed 'strong agreement' for 34 (89%) recommendations. The 2012 IAP/APA guidelines provide recommendations concerning key aspects of medical and surgical management of acute pancreatitis based on the currently available evidence. These recommendations should serve as a reference standard for current management and guide future clinical research on acute pancreatitis. Copyright © 2013 IAP and EPC. Published by Elsevier B.V.

Heterologous prime-boosting has emerged as a powerful vaccination approach against tuberculosis. However, optimal timing to boost BCG-immunity using subunit vaccines remains unclear in clinical trials. Here, we followed the adhesin Apa-specific T-cell responses in BCG-primed mice and investigated its BCG-booster potential. The Apa-specific T-cell response peaked 32-52 weeks after parenteral or mucosal BCG-priming but waned significantly by 78 weeks. A subunit-Apa-boost during the contraction-phase of BCG-response had a greater effect on the magnitude and functional quality of specific cellular and humoral responses compared to a boost at the peak of BCG-response. The cellular response increased following mucosal BCG-prime-Apa-subunit-boost strategy compared to Apa-subunit-prime-BCG-boost approach. However, parenteral BCG-prime-Apa-subunit-boost by a homologous route was the most effective strategy in-terms of enhancing specific T-cell responses during waning in the lung and spleen. Two Apa-boosters markedly improved waning BCG-immunity and significantly reduced Mycobacterium tuberculosis burdens post-challenge. Our results highlight the challenges of optimization of prime-boost regimens in mice where BCG drives persistent immune-activation and suggest that boosting with a heterologous vaccine may be ideal once the specific persisting effector responses are contracted. Our results have important implications for design of prime-boost regimens against tuberculosis in humans.

The affection of alginate-polylysine-alginate (APA) microcapsulation on catecholamine (CA) and leucine-enkephalin (L-EK) secretion from bovine adrenal medullary chromaffin cells was analysed. Encapsulating BCCs with the APA microcapsulation, the secretion of CA and L-EK in encapsulated BCCs was detected by high-performance liquid chromatography-electrochemical assay and radioimmunoassay, respectively. There is little difference between the encapsulated BCCs and the non-encapsulated BCCs in the secretion of epinephrine (E) and noradrenaline (NE) but the secretion of dopamine (DA) and L-EK in several points decline. The studies indicated that APA microcapsulation of BCCs didn't affect the secretion of E and NE, but did the secretion DA and L-EK in forepart

A case-control study aiming to evaluate the relationship between Bsm I and Apa I restriction fragment gene polymorphisms and colorectal cancer (CRC) was carried out in Kashmir, including a total of 368 subjects (180 cases and 188 controls). DNA samples extracted from the blood of the subjects were analyzed for 3' untranslated region (3' UTR) Apa I and Bsm I polymorphisms using restriction fragment length polymorphism-polymerase chain reaction (RFLP-PCR). A statistically significant 2.7-fold increased risk was observed in individuals found homozygous for the presence of the 'b' allele, in comparison to subjects homozygous for the 'B' allele (odds ratio (OR) 2.7, 95% confidence interval (CI) 1.49-4.86 (Bsm I)), and a statistically insignificant 2-fold increased risk was found among individuals with the 'aa' genotype, as compared to subjects with the 'AA' genotype (OR 2.017, 95% CI 0.86-4.7). Our study also yielded statistically significant results when the Apa I polymorphism was stratified by age (≤ 50 years) and dwelling area (rural area), and the Bsm I polymorphism by gender (male gender), suggesting a possible role of Apa I and Bsm I polymorphisms in the etiology of CRC in Kashmir. We conclude that Apa I and Bsm I single-nucleotide polymorphisms (SNPs) in the vitamin D receptor gene (VDR) might be associated with susceptibility to CRC among Kashmiris. © 2014 S.

Vitamin D Receptor (VDR) is a transacting transcription factor which mediates immunomodulatory function and plays a key role in innate and adaptive immune responses through its ligand and polymorphisms in VDR gene may affect its regulatory function. To investigate the association of three VDR gene polymorphisms (TaqI rs731236, FokI rs2228570 and ApaI rs7975232) with leprosy. The study group includes 404 participants of which 222 were leprosy patients (paucibacillary=87, multibacillary=135) and 182 healthy controls. Genotyping was done using PCR-RFLP technique. Statistical analysis was performed using SNP Stats and PLINK software. The VDR FokI (rs2228570) ff genotype, ApaI (rs7975232) AA, Aa genotype and haplotype T-f-a, T-F-A were positively associated with leprosy when compared to healthy controls. The two variants at Fok and Apa positions in VDR gene are significantly associated with leprosy. Genotypes at FokI (ff), ApaI (aa) and haplotype (T-F-a, T-f-a) may contribute to the risk of developing leprosy by altering VDR phenotype/levels subsequently modulation of immune response.

Apa-Tappi Whole-Tree Utilization Committee: review of achievements

Energy Technology Data Exchange (ETDEWEB)

Plummer, G M

1978-03-01

The Apa-Tappi Whole-Tree Utilization Committee started its activities in mid-1974 with people who pioneered the concept of whole-tree chipping. The major problem retarding expansion of use of these chips was determined to be grit and dirt, which is primarily associated with bark and foliage. Utilization of research and tests by member companies and communication with manufacturers resulted in commercial applications that improved chip quality. Other achievements have been the establishment of a nationwide project to develop tree-weight tables, documentation of associated problems, harvesting equipment improvements, screening and separation advances, and needed research work.

Delgado Sánchez-Mateos, Juan

2007-05-01

Some basic characteristics, not always explicit, of the editorial style proposed by the American Psychological Association (APA), and from the objections posed by some authors who maintain critical positions towards the use of this style, are reviewed, starting with the work of Madigan, Johnson, and Linton (1995) and the subsequent controversy. Starting with this review, problems related to underlying assumptions of the style, with ethical aspects of research, and with the epistemological positions defended by the different traditions of research are discussed. In the conclusions, a simpler differentiation between the scientific-technical and communicative-practical systems of enquiry is proposed, and an explicit commitment, in the text of the report, to the ethical responsibilities derived from the authorship and the development of the research.

2017-10-01

APA is celebrating 125 years this year and at the journal we are commemorating this milestone with a special issue. The inspiration came from our editorial team, who wished to acknowledge the links between game-changing articles that have influenced our research community in the past-we call them classics for short-and contemporary works. The main idea was to feature the work of nine contemporary research teams, while at the same time drawing readers' attention to their links with the classics. In this introduction, we have organized the articles according to several broad themes: active perception, perception for action, action alters perception, perception of our bodies in action, and acting on selective perceptions. As all who have read and contributed to the journal over the past few years have come to realize, it is no longer possible to study perception without considering its role in action. Nor is it possible to study action (formerly called performance , as reflected in the journal title) without understanding the perceptual contributions to action. These nine articles each exemplify, in their own way, how these dynamic interactions play out in contemporary research in our field. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

APA guidelines: their importance and a plan to keep them current: 2013 annual report of the Policy and Planning Board.

Science.gov (United States)

2014-01-01

When guidelines are approved by APA, they become association policy, and it is imperative that they remain current. The revision of guidelines poses several challenges to the association. These challenges range from the availability and allocation of resources to support the complicated processes involved in developing and updating these policies to the lack of a clearly defined process that includes identification of tasks, assignments of responsibilities, and so forth. For this reason, the APA Board of Directors asked the Policy and Planning Board (P&P) to work with the boards of the four directorates (i.e., the Education Directorate, the Practice Directorate, the Public Interest Directorate, and the Science Directorate) to create a proposal that would (a) make recommendations with regard to how the review and revision of guidelines documents might best be accomplished in accordance with the APA Strategic Plan and existing policies and procedures and (b) make suggestions regarding the association resources that might be required. The Board of Directors approved the proposed review process in December 2013. 2014 APA, all rights reserved

A full-scale test was conducted with an up-flow anaerobic sludge blanket (UASB) pre-treating pharmaceutical wastewater containing 6-aminopenicillanic acid (6-APA) and amoxicillin. The aim of the study is to investigate the performance of UASB in the condition of a high chemical oxygen demand (COD) loading rate from 12.57 to 21.02 kgm(-3)d(-1) and a wide pH from 5.57 to 8.26, in order to provide a reference for treating the similar chemical synthetic pharmaceutical wastewater containing 6-APA and amoxicillin. The results demonstrated that the UASB average percentage reduction in COD, 6-APA and amoxicillin were 52.2%, 26.3% and 21.6%, respectively. In addition, three models, built on the back propagation neural network (BPNN) theory and linear regression techniques were developed for the simulation of the UASB system performance in the biodegradation of pharmaceutical wastewater containing 6-APA and amoxicillin. The average error of COD, 6-APA and amoxicillin were -0.63%, 2.19% and 5.40%, respectively. The results indicated that these models built on the BPNN theory were well-fitted to the detected data, and were able to simulate and predict the removal of COD, 6-APA and amoxicillin by UASB.

2014-11-01

The Edwin B. Newman Graduate Research Award is given jointly by Psi Chi and APA. The award was established to recognize young researchers at the beginning of their professional lives and to commemorate both the 50th anniversary of Psi Chi and the 100th anniversary of psychology as a science (dating from the founding of Wundt's laboratory). The 2014 recipient is Sümeyra Tosun. Tosun was chosen for "an outstanding research paper that examines the cognitive repercussions of obligatory versus optional marking of evidentiality, the linguistic coding of the source of information. In English, evidentiality is conveyed in the lexicon through the use of adverbs. In Turkish, evidentiality is coded in the grammar. In two experiments, it was found that English speakers were equally good at remembering and monitoring the source of firsthand information and the source of non-firsthand information. Turkish speakers were worse at remembering and monitoring non-firsthand information than firsthand information and were worse than English speakers at remembering and monitoring non-firsthand information." Tosun's award citation, biography, and a selected bibliography are presented here. PsycINFO Database Record (c) 2014 APA, all rights reserved.

Oscillatory transenantiomerization of the selected 2-arylpropionic acid (2-APAs) in vitro as a spontaneous phenomenon

International Nuclear Information System (INIS)

Sajewicz, M.; Alska, T.K.

2006-01-01

In this paper, we summarize the results of our earlier investigations on an attempted enantioseparation of the selected 2-arylpropionic acids (2-APAs) by means of the chiral thin layer chromatography (TLC). These results have been originally presented in a series of the research papers published in several chromatography journals. In the current article it was reminded that the prolonged storage of the investigated 2-APAs in the aqueous and the non-aqueous solutions results in an oscillatory change of the respective retardation factor (RF) and the specific rotation (alfa)/sub P/) values. An assumption is introduced as to the chemical nature of the observed phenomenon. It is assumed that the observed oscillations are due to the repeated structural inversion (in our study labelled as oscillatory transenantiomerization) of one enantiomer to its respective antimer. One attempts to at least roughly explain the molecular mechanism of transenantiomerization either by keto-enol tautomerism, or by formation of an intermediate enolic anion, any of these two reaction mechanisms possible only in the basic environment. Then one reflects on the most probable mechanism responsible for the oscillatory nature of the observed structural inversion. It is concluded that the oscillations could be due to an enhanced viscosity of the investigated 2-APA solutions (as compared with those of the respective pure solvents) and/or due to the molecular self-organization within these solutions, resulting in anisotropic properties thereof. Finally, it is concluded that an ultimate explanation of the observed oscillatory transenantiomerization of the selected 2-APAs could probably be offered by the Brusselator-type kinetic model implemented with the diffusion term. In the last section of this paper, argumentation is presented strongly in favour of this particular model and against any alternative speculation as to the supramolecular nature of the observed oscillatory phenomena.

Are adolescents less mature than adults?: minors' access to abortion, the juvenile death penalty, and the alleged APA "flip-flop".

Science.gov (United States)

Steinberg, Laurence; Cauffman, Elizabeth; Woolard, Jennifer; Graham, Sandra; Banich, Marie

2009-10-01

The American Psychological Association's (APA's) stance on the psychological maturity of adolescents has been criticized as inconsistent. In its Supreme Court amicus brief in Roper v. Simmons (2005), which abolished the juvenile death penalty, APA described adolescents as developmentally immature. In its amicus brief in Hodgson v. Minnesota (1990), however, which upheld adolescents' right to seek an abortion without parental involvement, APA argued that adolescents are as mature as adults. The authors present evidence that adolescents demonstrate adult levels of cognitive capability earlier than they evince emotional and social maturity. On the basis of this research, the authors argue that it is entirely reasonable to assert that adolescents possess the necessary skills to make an informed choice about terminating a pregnancy but are nevertheless less mature than adults in ways that mitigate criminal responsibility. The notion that a single line can be drawn between adolescence and adulthood for different purposes under the law is at odds with developmental science. Drawing age boundaries on the basis of developmental research cannot be done sensibly without a careful and nuanced consideration of the particular demands placed on the individual for "adult-like" maturity in different domains of functioning.

Herpes simplex virus type 1 (HSV-1) is responsible of common and widespread viral infections in humans through the world, and of rare, but extremely severe, clinical syndromes in the central nervous system. The emergence of resistant strains to drugs actually in use encourages the searching for novel antiviral compounds, including those of natural origin. In this study, the recently described poly-γ-glutamic acid (γ-PGA-APA), produced by the marine thermotolerant Bacillus horneckiae strain APA, and previously shown to possess biological and antiviral activity, was evaluated for its anti-HSV-1 and immunomodulatory properties. The biopolymer hindered the HSV-1 infection in the very early phase of virus replication. In addition, the γ-PGA-APA was shown to exert low cytotoxicity and noticeable immunomodulatory activities towards TNF-α and IL-1β gene expression. Moreover, the capacity to positively modulate the transcriptional activity of the cytokine genes was paired with increased level of activation of the transcription factor NF-kB by γ-PGA-APA. Overall, as non-cytotoxic biopolymer able to contribute in the antiviral defense against HSV-1, γ-PGA-APA could lead to the development of novel natural drugs for alternative therapies.

Acanthamoeba plasminogen activator (aPA) is a serine protease elaborated by Acanthamoeba trophozoites that facilitates the invasion of trophozoites to the host and contributes to the pathogenesis of Acanthamoeba keratitis (AK). The aim of this study was to explore if aPA stimulates proinflammatory cytokine in human corneal epithelial (HCE) cells via the protease-activated receptors (PARs) pathway. Acanthamoeba castellanii trophozoites were grown in peptone-yeast extract glucose for 7 days, and the supernatants were collected and centrifuged. The aPA was purified using the fast protein liquid chromatography system, and aPA activity was determined by zymography assays. Human corneal epithelial cells were incubated with or without aPA (100 μg/mL), PAR1 agonists (thrombin, 10 μM; TRAP-6, 10 μM), and PAR2 agonists (SLIGRL-NH2, 100 μM; AC 55541, 10 μM) for 24 and 48 hours. Inhibition of PAR1 and PAR2 involved preincubating the HCE cells for 1 hour with the antagonist of PAR1 (SCH 79797, 60 μM) and PAR2 (FSLLRY-NH2, 100 μM) with or without aPA. Human corneal epithelial cells also were preincubated with PAR1 and PAR2 antagonists and then incubated with or without PAR1 agonists (thrombin and TRAP-6) and PAR2 agonists (SLIGRL-NH2 and AC 55541). Expression of PAR1 and PAR2 was examined by quantitative RT-PCR (qRT-PCR), flow cytometry, and immunocytochemistry. Interleukin-8 expression was quantified by qRT-PCR and ELISA. Human corneal epithelial cells constitutively expressed PAR1 and PAR2 mRNA. Acanthamoeba plasminogen activator and PAR2 agonists significantly upregulated PAR2 mRNA expression (1- and 2-fold, respectively) (P aPA, and PAR2 agonists induced PAR2 mRNA expression in HCE cells (P aPA, significantly upregulated PAR1 mRNA expression, which was significantly inhibited by PAR1 antagonist in HCE cells. Acanthamoeba plasminogen activator and PAR2 agonists stimulated IL-8 mRNA expression and protein production, which is significantly diminished by PAR2 antagonist

Full Text Available One precondition of contribution of a discipline to its field, to the scientific word in general and to the entire humankind is producing qualified scientific publications in the related field or discipline. National and international standard(s provided for citing and referencing tables and figures, in addition to the content (and context of the scientific publications might provide the relevant publication to be more widely and correctly read and reviewed. This study deals with adaptation of the latest edition of the American Psychological Association (APA rules. This book, where the APA rules -already a universal authority in citing and referencing- are enriched with specific examples for every type of information source, is a basic reference source after Prof. Dr. S. Kurbanoğlu’s “Kaynak Gösterme El Kitabı” (Referencing Handbook in 2004 that can be implemented not only to the Information and Records Management field, but to the whole scientific world. The meaning and importance of the work of Şencan and Doğan, is much more profound in our country where along with the quality of the scientific publications, the stylistic compatibility with the scientific criteria is also very often questioned.

The ApaH-like phosphatase TbALPH1 is the major mRNA decapping enzyme of trypanosomes.

Full Text Available 5'-3' decay is the major mRNA decay pathway in many eukaryotes, including trypanosomes. After deadenylation, mRNAs are decapped by the nudix hydrolase DCP2 of the decapping complex and finally degraded by the 5'-3' exoribonuclease. Uniquely, trypanosomes lack homologues to all subunits of the decapping complex, while deadenylation and 5'-3' degradation are conserved. Here, I show that the parasites use an ApaH-like phosphatase (ALPH1 as their major mRNA decapping enzyme. The protein was recently identified as a novel trypanosome stress granule protein and as involved in mRNA binding. A fraction of ALPH1 co-localises exclusively with the trypanosome 5'-3' exoribonuclease XRNA to a special granule at the posterior pole of the cell, indicating a connection between the two enzymes. RNAi depletion of ALPH1 is lethal and causes a massive increase in total mRNAs that are deadenylated, but have not yet started 5'-3' decay. These data suggest that ALPH1 acts downstream of deadenylation and upstream of mRNA degradation, consistent with a function in mRNA decapping. In vitro experiments show that recombinant, N-terminally truncated ALHP1 protein, but not a catalytically inactive mutant, sensitises the capped trypanosome spliced leader RNA to yeast Xrn1, but only if an RNA 5' polyphosphatase is included. This indicates that the decapping mechanism of ALPH1 differs from the decapping mechanism of Dcp2 by leaving more than one phosphate group at the mRNA's 5' end. This is the first reported function of a eukaryotic ApaH-like phosphatase, a bacterial-derived class of enzymes present in all phylogenetic super-groups of the eukaryotic kingdom. The substrates of eukaryotic ApaH-like phosphatases are unknown. However, the substrate of the related bacterial enzyme ApaH, diadenosine tetraphosphate, is highly reminiscent of a eukaryotic mRNA cap.

Effect of oxygen and nitroaromatic cell radiosensitizers on radiation-induced cleavage of internucleotide bonds: ApA, dApA, and poly(A)

Irradiation of the dinucleoside monophosphates ApA and dApA in deoxygenated solution leads to a preferential cleavage of the 3' end of the internucleotide bond. Cleavage at the 3' bond is favored to the extent of 2 to 1 over 5' cleavage. Oxygen and nitroaromatic compounds inhibit 3' bond breaking in ApA and dApA in agreement with earlier findings from studies of 3'- and 5'-mononucleotides. In contrast to the mononucleotide results, no enhancement of 5' cleavage is observed for ApA and dApA irradiated in the presence of oxygen or the nitroaromatic additives. The over-all effect of the additives is to decrease the combined (3' and 5') yield of internucleotide bond breaking in ApA and dApA. This phenomenon is also observed for polyadenylic acid in the presence of the nitroaromatics. Oxygen marginally enhances internucleotide bond breaking in polyadenylic acid (factor 1.1) over that seen in deoxygenated solution. Postirradiation alkaline hydrolysis of dApA leads to further ester cleavage revealing the presence of radiation-induced alkali-labile bonds. The number of these bonds decreases in the order oxygen greater than nitrofurans greater than nitrobenzenes approximately irradiation in the absence of additives

Glycosylation is the most abundant post-translational polypeptide chain modification in nature. Although carbohydrate modification of protein antigens from many microbial pathogens constitutes important components of B cell epitopes, the role in T cell immunity is not completely understood. Here, using ELISPOT and polychromatic flow cytometry, we show that O-mannosylation of the adhesin, Apa, of Mycobacterium tuberculosis (Mtb) is crucial for its T cell antigenicity in humans and mice after infection. However, subunit vaccination with both mannosylated and non-mannosylated Apa induced a comparable magnitude and quality of T cell response and imparted similar levels of protection against Mtb challenge in mice. Both forms equally improved waning BCG vaccine-induced protection in elderly mice after subunit boosting. Thus, O-mannosylation of Apa is required for antigenicity but appears to be dispensable for its immunogenicity and protective efficacy in mice. These results have implications for the development of subunit vaccines using post-translationally modified proteins such as glycoproteins against infectious diseases like tuberculosis.

The aim of the study was to explore the mechanisms underlying the association of birth weight with later body mass index (BMI) from the biochemical markers related to metabolism and the Apa I polymorphism in IGF-II gene. A total of 300 children were selected randomly from the Macrosomia Birth Cohort in Wuxi, China. The height and weight were measured and blood samples were collected. Plasma concentrations of 8 biochemical markers were detected. Apa I polymorphism was analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Biochemical markers were detected for 296 subjects and 271 subjects were genotyped for the Apa I polymorphism. No association was found between birth weight and 8 biochemical markers. In boys, the BMIs of AA, AG and GG genotypes were 16.10 ± 2.24 kg/m(2), 17.40 ± 3.20 kg/m(2), 17.65 ± 2.66 kg/m(2). And there was statistical difference among the three genotypes. But in girls, there was no statistical difference. The birth weights of AA, AG and GG genotypes were 3751.13 ± 492.43 g, 3734.00 ± 456.88 g, 3782.00 ± 461.78 g. And there was no statistical difference among the three genotypes. Biochemical markers are not associated with birth weight. Apa I polymorphism may be related to childhood BMI, but it may be not associated with birth weight. Therefore, biochemical markers and Apa I polymorphism might not play a role in the association of birth weight and BMI.

Putative alternative polyadenylation (APA) events in the early interaction of Salmonella enterica Typhimurium and human host cells.

The immune response of epithelial cells upon infection is mediated by changing activity levels of a variety of proteins along with changes in mRNA, and also ncRNA abundance. Alternative polyadenylation (APA) represents a mechanism that diversifies gene expression similar to alternative splicing. T-cell activation, neuronal activity, development and several human diseases including viral infections involve APA, but at present it remains unclear if this mechanism is also implicated in the response to bacterial infections. Our recently published study of interacting Salmonella enterica Typhimurium and human host cells includes genome-wide expression profiles of human epithelial cells prior and subsequent to infection with the invasive pathogen. The generated dataset (GEO accession number: GSE61730) covers several points of time post infection, and one of these interaction stages was additionally profiled with MACE-based dual 3'Seq, which allows for identification of polyadenylation (PA) sites. The present study features the polyadenylation landscape in early interacting cells based on this data, and provides a comparison of the identified PA sites with those of a corresponding 3P-Seq dataset of non-interacting cells. Differential PA site usage of FTL , PRDX1 and VAPA results in transcription of mRNA isoforms with distinct sets of miRNA and protein binding sites that influence processing, localization, stability, and translation of the respective mRNA. APA of these candidate genes consequently harbors the potential to modulate the host cell response to bacterial infection.

Full Text Available Abstract Background The Ala-Pro-rich O-glycoprotein known as the 45/47 kDa or APA antigen from Mycobacterium tuberculosis is an immunodominant adhesin restricted to mycobacterium genus and has been proposed as an alternative candidate to generate a new vaccine against tuberculosis or for diagnosis kits. In this work, the recombinant O-glycoprotein APA was produced by the non-pathogenic filamentous bacteria Streptomyces lividans, evaluating three different culture conditions. This strain is known for its ability to produce heterologous proteins in a shorter time compared to M. tuberculosis. Results Three different shake flask geometries were used to provide different shear and oxygenation conditions; and the impact of those conditions on the morphology of S. lividans and the production of rAPA was characterized and evaluated. Small unbranched free filaments and mycelial clumps were found in baffled and coiled shake flasks, but one order of magnitude larger pellets were found in conventional shake flasks. The production of rAPA is around 3 times higher in small mycelia than in larger pellets, most probably due to difficulties in mass transfer inside pellets. Moreover, there are four putative sites of O-mannosylation in native APA, one of which is located at the carboxy-terminal region. The carbohydrate composition of this site was determined for rAPA by mass spectrometry analysis, and was found to contain different glycoforms depending on culture conditions. Up to two mannoses residues were found in cultures carried out in conventional shake flasks, and up to five mannoses residues were determined in coiled and baffled shake flasks. Conclusions The shear and/or oxygenation parameters determine the bacterial morphology, the productivity, and the O-mannosylation of rAPA in S. lividans. As demonstrated here, culture conditions have to be carefully controlled in order to obtain recombinant O-glycosylated proteins with similar "quality" in bacteria

The science of ethics: Deception, the resilient self, and the APA code of ethics, 1966-1973.

Science.gov (United States)

Stark, Laura

2010-01-01

This paper has two aims. The first is to shed light on a remarkable archival source, namely survey responses from thousands of American psychologists during the 1960s in which they described their contemporary research practices and discussed whether the practices were "ethical." The second aim is to examine the process through which the American Psychological Association (APA) used these survey responses to create principles on how psychologists should treat human subjects. The paper focuses on debates over whether "deception" research was acceptable. It documents how members of the committee that wrote the principles refereed what was, in fact, a disagreement between two contemporary research orientations. The paper argues that the ethics committee ultimately built the model of "the resilient self" into the APA's 1973 ethics code. At the broadest level, the paper explores how prevailing understandings of human nature are written into seemingly universal and timeless codes of ethics. © 2010 Wiley Periodicals, Inc.

Six Sigma methodology has been successfully applied to daily operations by several leading global private firms including GE and Motorola, to leverage their net profits. Comparatively, limited studies have been conducted to find out whether this highly successful methodology can be applied to research and development (R&D). In the current study, we have reviewed and proposed a process for a probable integration of Six Sigma methodology to large-scale production of Penicillin G and its subsequent conversion to 6-aminopenicillanic acid (6-APA). It is anticipated that the important aspects of quality control and quality assurance will highly benefit from the integration of Six Sigma methodology in mass production of Penicillin G and/or its conversion to 6-APA.

Ibuprofen and related 2-arylpropanoic acid (2-APA) drugs are often given as a racemic mixture and the R-enantiomers undergo activation in vivo by metabolic chiral inversion. The chiral inversion pathway consists of conversion of the drug to the coenzyme A ester (by an acyl-CoA synthetase) followed by chiral inversion by α-methylacyl-CoA racemase (AMACR; P504S). The enzymes responsible for hydrolysis of the product S-2-APA-CoA ester to the active S-2-APA drug have not been identified. In this study, conversion of a variety of 2-APA-CoA esters by human acyl-CoA thioesterase-1 and -2 (ACOT-1 and -2) was investigated. Human recombinant ACOT-1 and -2 (ACOT-1 and -2) were both able to efficiently hydrolyse a variety of 2-APA-CoA substrates. Studies with the model substrates R- and S-2-methylmyristoyl-CoA showed that both enzymes were able to efficiently hydrolyse both of the epimeric substrates with (2R)- and (2S)- methyl groups. ACOT-1 is located in the cytosol and is able to hydrolyse 2-APA-CoA esters exported from the mitochondria and peroxisomes for inhibition of cyclo-oxygenase-1 and -2 in the endoplasmic reticulum. It is a prime candidate to be the enzyme responsible for the pharmacological action of chiral inverted drugs. ACOT-2 activity may be important in 2-APA toxicity effects and for the regulation of mitochondrial free coenzyme A levels. These results support the idea that 2-APA drugs undergo chiral inversion via a common pathway. Copyright © 2013 Elsevier Inc. All rights reserved.

The APA concept was developed with the aim of increasing the PWR capacity to burn plutonium emerging from the recycling of irradiated fuels in the French park of nuclear power plants. At first, a concept using annular pins was optimised to allow a good consumption of plutonium while preserving an acceptable neutron control. To cope with the technological problems and those posed by the manufacture of these annular pins, an alternative concept is presented here. It poses as initial conditions the conservation of both the plutonium balance and the respect of the reactivity control. (authors)

The American Psychological Association Publications and Communications Board Working Group on Journal Article Reporting Standards for Qualitative Research (JARS-Qual Working Group) was charged with examining the state of journal article reporting standards as they applied to qualitative research and with generating recommendations for standards that would be appropriate for a wide range of methods within the discipline of psychology. These standards describe what should be included in a research report to enable and facilitate the review process. This publication marks a historical moment-the first inclusion of qualitative research in APA Style, which is the basis of both the Publication Manual of the American Psychological Association (APA, 2010) and APA Style CENTRAL, an online program to support APA Style. In addition to the general JARS-Qual guidelines, the Working Group has developed standards for both qualitative meta-analysis and mixed methods research. The reporting standards were developed for psychological qualitative research but may hold utility for a broad range of social sciences. They honor a range of qualitative traditions, methods, and reporting styles. The Working Group was composed of a group of researchers with backgrounds in varying methods, research topics, and approaches to inquiry. In this article, they present these standards and their rationale, and they detail the ways that the standards differ from the quantitative research reporting standards. They describe how the standards can be used by authors in the process of writing qualitative research for submission as well as by reviewers and editors in the process of reviewing research.

Vitamin D receptor (VDR) gene has an important role as a candidate gene for the regulation of bone mass in osteoporosis. However, its association with bone mineral density (BMD) is controversial and has not been established in different ethnic populations. To enhance the understanding of VDR gene polymorphism in the context of BMD, we investigated the plausible genetic association of TaqI and ApaI polymorphism with BMD in North Indian postmenopausal women with osteoporosis.254 osteoporotic women (Age 55.82 ± 6.91) and 254 postmenopausal non osteoporotic women (Age 54.76 ± 6.26) were included in the study. VDR TaqI and ApaI polymorphism were determined by PCR (polymerase chain reaction) and RFLP (restriction fragment length polymorphism). BMD was assessed by dual energy X-ray absorptiometry (DXA) at the lumbar spine (L 1 -L 4 ), hip, forearm and femoral neck. The average BMD with TT genotype was significantly lower at lumbar spine, hip and forearm. The Frequency of TT genotype and t allele was significantly high in osteoporotic women when compared with controls. The average BMD with Aa genotype was higher in ApaI. Furthermore, comparison of frequency distribution of genotype and allele for VDR ApaI between osteoporotic patients and controls did not show any significant difference. Our findings revealed that TaqI gene TT genotype was associated with low BMD in North Indian osteoporotic women. Moreover, TT genotype and t allele associated significantly with osteoporosis in postmenopausal women. Therefore, VDR TaqI gene is an important determinant of risk factor for osteoporosis.

Full Text Available Probiotics possess potential therapeutic and preventative effects for various diseases and metabolic disorders. One important limitation for the oral delivery of probiotics is the harsh conditions of the upper gastrointestinal tract (GIT which challenge bacterial viability and activity. One proposed method to surpass this obstacle is the use of microencapsulation to improve the delivery of bacterial cells to the lower GIT. The aim of this study is to use alginate-poly-L-lysine-alginate (APA microcapsules to encapsulate Lactobacillus fermentum NCIMB 5221 and characterize its enzymatic activity and viability through a simulated GIT. This specific strain, in previous research, was characterized for its inherent ferulic acid esterase (FAE activity which could prove beneficial in the development of a therapeutic for the treatment and prevention of cancers and metabolic disorders. Our findings demonstrate that the APA microcapsule does not slow the mass transfer of substrate into and that of the FA product out of the microcapsule, while also not impairing bacterial cell viability. The use of simulated gastrointestinal conditions led to a significant 2.5 log difference in viability between the free (1.10 × 104 ± 1.00 × 103 cfu/mL and the microencapsulated (5.50 × 106 ± 1.00 × 105 cfu/mL L. fermentum NCIMB 5221 following exposure. The work presented here suggests that APA microencapsulation can be used as an effective oral delivery method for L. fermentum NCIMB 5221, a FAE-active probiotic strain.

The work presented here suggests that APA microencapsulation can be used as an effective oral delivery method for L. fermentum NCIMB 5221, a FAE-active probiotic strain.

Immobilized penicillin acylase was used for bioconversion of penicillin PG into 6-APA in aqueous two-phase systems consisting of a light-sensitive polymer PNBC and a pH-sensitive polymer PADB. Partition coefficients of 6-APA was found to be about 5.78 in the presence of 1% NaCl. Enzyme kinetics showed that the reaction reached equilibrium at roughly 7 h. The 6-APA mole yields were 85.3% (pH 7.8, 20 degrees C), with about 20% increment as compared with the reaction of single aqueous phase buffer. The partition coefficient of PG (Na) varied scarcely, while that of the product, 6-APA and phenylacetic acid (PA) significantly varied due to Donnan effect of the phase systems and hydrophobicity of the products. The variation of the partition coefficients of the products also affected the bioconversion yield of the products. In the aqueous two-phase systems, the substrate, PG, the products of 6-APA and PA were biased in the top phase, while immobilized penicillin acylase at completely partitioned at the bottom. The substrate and PG entered the bottom phase, where it was catalyzed into 6-APA and PA and entered the top phase. Inhibition of the substrate and products was removed to result in improvement of the product yield, and the immobilized enzyme showed higher efficiency than the immobilized cells and occupied smaller volume. Compared with the free enzyme, immobilized enzyme had greater stability, longer life-time, and was completely partitioned in the bottom phase and recycle. Bioconversion in two-phase systems using immobilized penicillin acylase showed outstanding advantage. The light-sensitive copolymer forming aqueous two-phase systems could be recovered by laser radiation at 488 nm or filtered 450 nm light, while pH-sensitive polymer PADB could be recovered at the isoelectric point (pH 4.1). The recovery of the two copolymers was between 95% and 99%.

Mycobacterium bovis BCG prime DNA (Mycobacterium tuberculosis genes)-booster vaccinations have been shown to induce greater protection against tuberculosis (TB) than BCG alone. This heterologous prime-boost strategy is perhaps the most realistic vaccination for the future of TB infection control, especially in countries where TB is endemic. Moreover, a prime-boost regimen using biodegradable microspheres seems to be a promising immunization to stimulate a long-lasting immune response. The alanine proline antigen (Apa) is a highly immunogenic glycoprotein secreted by M. tuberculosis. This study investigated the immune protection of Apa DNA vaccine against intratracheal M. tuberculosis challenge in mice on the basis of a heterologous prime-boost regimen. BALB/c mice were subcutaneously primed with BCG and intramuscularly boosted with a single dose of plasmid carrying apa and 6,6'-trehalose dimycolate (TDM) adjuvant, coencapsulated in microspheres (BCG-APA), and were evaluated 30 and 70 days after challenge. This prime-boost strategy (BCG-APA) resulted in a significant reduction in the bacterial load in the lungs, thus leading to better preservation of the lung parenchyma, 70 days postinfection compared to BCG vaccinated mice. The profound effect of this heterologous prime-boost regimen in the experimental model supports its development as a feasible strategy for prevention of TB.

New homologs of bent molecules with a large bent-angle central core of 4,6-dichloro benzene and an alkylthio terminal tail have been synthesized. Although the corresponding alkoxy-tail homologs show only the calamitic phases because of its large bent angles around 160°, the new homologs with an alkylthio tail exhibit the antiferroelectric smectic APA (SmAPA) banana phase that is transformed on cooling from the calamitic smectic A (SmA) phase. The biaxial polar packing of bent molecules in the SmAPA phase is considered to arise from the hindered rotation around the molecular long axis due to the expansion of the mesophase temperatures to a lower temperature region. This study indicates that the bent molecules, even with a large bent angle, have the potential to form a switchable banana phase with a remarkable decrease in its phase temperature range to around 60 °C.

To evaluate vitamin D receptor (VDR) gene polymorphisms in Korean patients so as to identify the candidate genes associated with urinary stones. Urinary stones are a multifactorial disease that includes various genetic factors. A normal control group of 535 healthy subjects and 278 patients with urinary stones was evaluated. Of 125 patients who presented stone samples, 102 had calcium stones on chemical analysis. The VDR gene Alw I, Fok I, Apa I, and Taq I polymorphisms were evaluated using the polymerase chain reaction-restriction fragment length polymorphism analysis. Allelic and genotypic frequencies were calculated to identify associations in both groups. The haplotype frequencies of the VDR gene polymorphisms for multiple loci were also determined. For the VDR gene Alw I, Fok I, Apa I, and Taq I polymorphisms, there was no statistically significant difference between the patients with urinary stones and the healthy controls. There was also no statistically significant difference between the patients with calcium stones and the healthy controls. A novel haplotype (Ht 4; CTTT) was identified in 13.5% of the patients with urinary stones and in 8.3% of the controls (P = .001). The haplotype frequencies were significantly different between the patients with calcium stones and the controls (P = .004). The VDR gene Alw I, Fok I, Apa I, and Taq I polymorphisms does not seem to be candidate genetic markers for urinary stones in Korean patients. However, 1 novel haplotype of the VDR gene polymorphisms for multiple loci might be a candidate genetic marker. Copyright 2010 Elsevier Inc. All rights reserved.

The Mycobacterium tuberculosis cell-surface glycoprotein apa as a potential adhesin to colonize target cells via the innate immune system pulmonary C-type lectin surfactant protein A.

Tuberculosis is still a major health problem, and understanding the mechanism by which Mycobacterium tuberculosis (Mtb) invades and colonizes its host target cells remains an important issue for the control of infection. The innate immune system C-type lectins (C-TLs), including the human pulmonary surfactant protein A (PSP-A), have been recently identified as determinant players in the early recognition of the invading pathogen and in mounting the host defense response. Although the antigenic lipoglycan mannosylated lipoarabinomannan is currently considered to be the major C-TL target on the mycobacterial surface, the recognition by some C-TLs of the only mycobacterial species composing the "Mtb complex" indicates that mannosylated lipoarabinomannan cannot account alone for this specificity. Thus, we searched for the mycobacterial molecules targeted by human PSP-A, focusing our attention on the Mtb surface glycoproteins. We developed an original functional proteomic approach based on a lectin blot assay using crude human bronchoalveolar lavage fluid as a source of physiological PSP-A. Combined with selective cell-surface protein extraction and mass spectrometry peptide mapping, this strategy allowed us to identify the Apa (alanine- and proline-rich antigenic) glycoprotein as new potential target for PSP-A. This result was supported by direct binding of PSP-A to purified Apa. Moreover, EDTA addition or deglycosylation of purified Apa samples completely abolished the interaction, demonstrating that the interaction is calcium- and mannose-dependent, as expected. Finally, we provide convincing evidence that Apa, formerly considered as mainly secreted, is associated with the cell wall for a sufficiently long time to aid in the attachment of PSP-A. Because, to date, Apa seems to be restricted to the Mtb complex strains, we propose that it may account for the selective recognition of those strains by PSP-A and other immune system C-TLs containing homologous functional

"Bad girls rule": an interdisciplinary feminist commentary on the report of the APA Task Force on the Sexualization of Girls.

Science.gov (United States)

Lerum, Kari; Dworkin, Shari L

2009-01-01

Feminist, critical, and postmodern scholars have long recognized sexuality as a site of power relations. The recently released Report of the APA (American Psychological Association) Task Force on the Sexualization of Girls is a welcome addition to ongoing feminist and activist conversations on how to intervene on issues of sexuality in the name of girls' and women's health. This article offers a critical interdisciplinary analysis of this influential APA report, expanding on and challenging several of its main claims. This article critiques the report as over-determining the negative impact of sexualization; offers other literatures as critical additions including feminist literature on media, consumer culture, gender, and the body, and earlier "pro-desire" feminist psychology scholarship; and critiques the task force's conflations of objectification and sexualization. The article concludes with a call for broadening feminist scholarship and activism across disciplinary boundaries to emphasize girls' and women's sexual agency and resistance, as well as sexual health and rights.

Apa-I polymorphism in VDR gene is related to metabolic syndrome in polycystic ovary syndrome: a cross-sectional study.

2018-04-18

Polycystic ovary syndrome (PCOS) is a common endocrine disorder determined by polygenic traits as well as environmental factors. Lower vitamin D levels have been detected in PCOS women and related to hormone and metabolic disturbances. Vitamin D acts in tissues through the vitamin D receptor (VDR). VDR gene variants have been associated with worse metabolic profile in the general population. We investigated the genotype and haplotype distribution of the Bsm-I (rs1544410), Apa-I (rs7975232), and Taq-I (rs731236) VDR gene polymorphisms in PCOS and non-hirsute women from southern Brazil. We further investigated the associations of these gene variants and their haplotypes with PCOS, vitamin D levels, and metabolic abnormalities, including the metabolic syndrome (MetS). A group of 191 women with PCOS (Rotterdam criteria) and 100 non-hirsute controls with regular ovulatory cycles were genotyped for all polymorphisms by real-time PCR, with allelic discrimination assays. MetS and the cutoffs for its isolated components were defined in accordance with the Joint Scientific Statement. Women with PCOS were younger and had significantly higher BMI and total testosterone levels than controls (p Apa-I entailed higher risk of MetS in PCOS (OR: 2.133; 95% CI 1.020-4.464, p = 0.042), and was associated with higher systolic blood pressure (p = 0.009), total cholesterol (p = 0.040), and LDL-cholesterol (p = 0.038) in both PCOS and control groups (two-way ANOVA). The frequencies of VDR haplotypes were similar in PCOS and control women. The present results suggest that the Apa-I variant in VDR gene may be associated with MetS in southern Brazilian women with PCOS, and with blood pressure, total cholesterol, and LDL-c in women with and without PCOS.

Appelbaum, B C; Appelbaum, P S; Grisso, T

1998-09-01

In the wake of the U.S. Supreme Court's 1990 decision in Zinermon v. Burch, renewed attention has been given to capacities patients must have to be considered competent to consent to voluntary hospitalization. An American Psychiatric Association (APA) task force suggested that strong policy interests support the establishment of a low threshold for competence in this situation. The study examined whether, as previous research suggested, patients would have difficulty meeting even this lenient standard. One hundred voluntarily hospitalized psychiatric patients were read two brief paragraphs, one explaining the purposes of psychiatric hospitalization and and the other explaining policies for discharge. The paragraphs' readability measured about eighth-grade level. After each paragraph, participants were read two sets of questions, one testing recall of the presented information and the other testing recognition of the information in a true-false format. The scores of patients grouped by selected demographic and clinical variables were compared. The vast majority of patients were able to comprehend the information that the APA task force suggested was relevant to their decision. However, a subgroup of patients who were initially admitted involuntarily had significantly poorer performance and may constitute a group who need special educational efforts focused on the consequences of voluntary admission.

Aberrant expression of gonadotropin-releasing hormone receptor (GnRHR) has been reported in human adrenal tissues including aldosterone-producing adenoma (APA). However, the details of its expression and functional role in adrenals are still not clear. In this study, quantitative RT-PCR analysis revealed the mean level of GnRHR mRNA was significantly higher in APAs than in human normal adrenal (NA) (P=0.004). GnRHR protein expression was detected in human NA and neoplastic adrenal tissues. In H295R cells transfected with GnRHR, treatment with GnRH resulted in a concentration-dependent increase in CYP11B2 reporter activity. Chronic activation of GnRHR with GnRH (100nM), in a cell line with doxycycline-inducible GnRHR (H295R-TR/GnRHR), increased CYP11B2 expression and aldosterone production. These agonistic effects were inhibited by blockers for the calcium signaling pathway, KN93 and calmidazolium. These results suggest GnRH, through heterotopic expression of its receptor, may be a potential regulator of CYP11B2 expression levels in some cases of APA. Copyright © 2014 Elsevier Ireland Ltd.

Haddad, Shaden

2014-12-01

The vitamin D endocrine system regulates bone metabolism and calcium homeostasis as well as cellular proliferation and differentiation. Vitamin D receptor (VDR) mediates Vit-D activity, thus VDR gene polymorphisms may correlate with different diseases. This study aimed to determine the distribution of VDR gene (Taq-I and Apa-I) polymorphisms using a RFLP in unrelated normal healthy individuals of Syrian population. Allelic frequencies were 65% vs 35% and 66% vs 34% for T vs t and A vs a alleles, respectively. Genotype distribution was 36%, 58% and 6% for TT, Tt and tt and 42%, 47% and 10% for AA, Aa and aa, respectively. These results demonstrate that the frequency and distribution of the VDR polymorphisms in Syrian population are different from other populations worldwide.

A complete series of the 2 '-5 ' and 3 '-5 ' regioisomeric types of r(ApA) and 2 '-d(ApA) analogues with the α-hydroxy-phosphonate C3 '-O-P-CH(OH)-C4 ″ internucleotide linkage, isopolar but non-isosteric with the phosphodiester one, were synthesized and their hybridization properties with polyU studied. Due to the chirality on the 5 '-carbon atom of the modified internucleotide linkage bearing phosphorus and hydroxy moieties, each regioisomeric type of ApA dimer is split into epimeric pairs. To examine the role of the 5 '-hydroxyl of the α-hydroxy-phosphonate moiety during hybridization, the appropriate r(ApA) analogues with 3 '(2 ')-O-P-CH(2)-C4 ″ linkage lacking the 5 '-hydroxyl were synthesized. Nuclear magnetic resonance (NMR) spectroscopy study on the conformation of the modified sugar-phosphate backbone, along with the hybridization measurements, revealed remarkable differences in the stability of complexes with polyU, depending on the 5 '-carbon atom configuration. Potential usefulness of the α-hydroxy-phosphonate linkage in modified oligoribonucleotides is discussed.

Full Text Available El presente estudio descriptivo analiza los índices h de los presidentes de la American Psychological Association (APA desde 1940 hasta la actualidad. El índice h se calcula teniendo en cuenta el número de artículos publicados en las revistas de la Web of Science (WOS y las citas recibidas por los mismos en dicha base de datos. No se estableció un periodo de búsqueda y, por tanto, se analizaron todos los resultados incluidos en la WOS. El número total de resultados analizados fue de 16.676, de los cuales 3.734 fueron de los presidentes de la APA. Los resultados se presentan en forma de ranking y ponen de manifiesto que Albert Bandura y Alan Kazdin son los presidentes con un índice h más elevado, y en entre estos y los demás existe una diferencia considerable. Los resultados hacen especular que el criterio de productividad en artículos científicos no fue el criterio más importante para presidir esta institución.

The authors are currently investigating the potential for treatment optimization with the BSD APAS in tumors which are eccentrically located within the lower abdomen and pelvis. Attempts have been made to manipulate electric field (E-field) distribution during treatments through frequency changes and partial array activation (driving less than all four quadrants). Field shifts are qualitatively documented using the manufacturer's supplied diode array probes located at the patient/bolus interface in anterior, posterior and bilateral positions. Preliminary findings indicate that the internal E-field distributions can be manipulated to result in better treatment tolerance and better temperature distributions in selected target volumes. Phantom and clinical data are presented demonstrating the utility of these approaches

Full Text Available Mental retardation (MR, after years of mites and beliefs, finally was considered to be a neurological affection that should be treated by a medical intervention. Psychotropic drugs, if correctly prescribed, are able to improve the capacity of MR individuals to productively interact socially and reintegrate themselves to the society. This work has as an objective to quantify, by a descriptive study, the frequency of use of medicines by students of the APAE (Associação de Pais e Amigos dos Excepcionais from Londrina-PR, characterize those drugs and relate them to mental pathologies of major prevalence in the institution. To accomplish the objectives, a pool was conducted on a population of 147 students registered during the period from January/1989 to May/ 2003. The results shown the following medicines: antiepiletic (52.4%, neuroleptics (3.4%, hematopoietics (2.7%, anticolinergics and pro-kinetics agents (0.7% each. Fenobarbital was the most evident among the antiepiletic (29.8%. The prevalence of those drugs was higher among individuals with cerebral palsy (62.1% and lower for the Down syndrome group (17,24%. As a conclusion, we consider necessary to conduct research projects focusing on the dynamic of the personnel affected by MR, as well as to provide social assistance to destitute families. O retardo mental (RM, após anos de crenças e misticismos, finalmente passou a ser considerado uma afecção neurológica que deve ser tratada com intervenção médica. As drogas psicotrópicas, se administradas corretamente, podem permitir que os acometidos de RM recuperem a capacidade de interação social produtiva e reintegrem-se à sociedade. Este trabalho teve como objetivo verificar, por meio de estudo descritivo, a freqüência da utilização de medicamentos utilizados pelos alunos da APAE (Associação de Pais e Amigos dos Excepcionais de Londrina-PR, caracterizar essas drogas e relacionálas com as patologias mentais de maior prevalência na

There has been increasing interest in the study of the association between Vitamin D receptor (VDR) gene polymorphisms and risk of chronic periodontitis. However, the results remain inconclusive. To better understand the roles of VDR polymorphisms (BsmI, TaqI, FokI, and ApaI) in chronic periodontitis susceptibility, we conducted this systematic review and meta-analysis. The PubMed, Google Scholar, and Web of Science database were systemically searched to determine all the eligible studies about VDR polymorphisms and risk of chronic periodontitis up to April 2017. Odds ratio (OR) and 95% confidence interval (CI) were used to evaluate the associations between VDR polymorphisms and chronic periodontitis risk. All the statistical analyses were performed by Comprehensive Meta-Analysis. All P values were two-tailed with a significant level at 0.05. Finally, a total of 38 case-control studies in 19 publications were identified which met our inclusion criteria. There are ten studies with 866 chronic periodontitis cases and 786 controls for BsmI, 16 studies with 1570 chronic periodontitis cases and 1676 controls for TaqI, five studies with 374 chronic periodontitis cases and 382 controls for FokI, and seven studies with 632 chronic periodontitis cases and 604 controls for ApaI. Overall, no significant association was observed between VDR gene BsmI, TaqI, FokI, and ApaI polymorphisms and risk of chronic periodontitis in any genetic model. Subgroup analysis stratified by ethnicity suggested a significant association between BsmI polymorphism and chronic periodontitis risk in the Caucasian subgroup under allele model (A vs. G: OR = 1.747, 95% CI = 1.099-2.778, P = 0.018). Further, no significant associations were observed when stratified by Hardy-Weinberg equilibrium status for BsmI, TaqI, and ApaI. Our results suggest that BsmI, TaqI, FokI, and ApaI polymorphisms in the VDR gene might not be associated with risk of chronic periodontitis in overall population.

Apesar de tal fato e de ser uma área de proteção desde 1981, a APA São José vem sofrendo com degradações ambientais. Dentro desse contexto, emergiu a questão de se valorar a APA São José com o objetivo de fornecer subsídios para a elaboração e consecução de políticas públicas e de projetos públicos e privados de conservação ou exploração sustentável do referido ativo. Como método de valoração, utilizou-se a valoração contingente, por meio da abordagem de Hanemann (1984 e o método de bootstrapping, para obter uma disposição a pagar (DAP mensal por família dos cinco municípios que compreendem a APA São José, de R$ 22,88, com um desvio padrão relativamente baixo de R$ 3,25.

Observa-se uma sub-representação dos setores populares, e os representantes de renda média-alta temem a favelização da região. Conseqüentemente, o conflito ambiental surge em torno da perda da qualidade ambiental nas referidas áreas, em parte associada às alternativas de habitação popular, abrindo oportunidade para discursos que justifiquem a segregação social no espaço e a elitização da paisagem em questão.This paper talks about the power relations within the consultative council of the APA-Sul, a conservation area situated in the Metropolitan Region of Belo Horizonte. There the lower-class sectors are apparently underrepresented and higher middle class representatives are concerned about the slumisation of the region. Consequently an environmental conflict arises about the loss of "environmental quality" of the area, partly associated with lower class housing, providing opportunities of discourses to justify social segregation in space and the elitization of the landscape at stake.

We offer a critical and constructive appraisal of the conclusions provided by the Interdivisional (American Psychological Association [APA] Divisions 12 & 29) Task Force on Evidence-Based Therapy Relationships. We highlight problems in overlapping terminology and definitions, as well as problems in the conduct of its meta-analyses (i.e., duplication of studies between reviews, inappropriate study inclusion, and use of measures of specific constructs for the calculation of effects for multiple relationship elements). On this basis, we express reservation about the conclusions offered by the APA Task Force. This special issue explores whether there are other therapeutic relationship elements that warrant consideration and further study. We were particularly interested in those elements that showed promise based on empirical or theoretical grounds, and in each article, we asked for an account of how the case formulation would guide the methods of adaptation for each individual client, and how the element would contribute to clinically relevant changes. © 2015 Wiley Periodicals, Inc.

Full Text Available The media play a pivotal role in the democratization process in Indonesia and this is among others apparent in the surge of films, both fiction and documentaries that have been produced after the end Suharto’s decades of control over the media. It is important to note, however, that compared with fiction films, the documentary genre remains rather unpopular in Indonesia. Indonesian documentary films struggle to depict stories of the subaltern and those living in the “periphery” in order for them to be seen and heard by the greater masses and by those in power – the ones in the “centre” or Jakarta. This paper discusses the connection between urban and rural voices and its impact in the documentary films Nona nyonya? (Miss mrs?, 2008 and Untuk apa? (What’s the point?, 2008 produced by Kalyana Shira Films, an organization well-known for its work on gender issues using film as medium. Departing from the notion that the film industry itself is still largely Jakarta-centred, this article focuses on the way urban settings and voices are used to create rhetoric, and the impact of the domination of these urban voices over the rural ones.

Full Text Available Three adjacent single nucleotide polymorphisms of the vitamin D receptor gene (VDR BsmI (rs1544410, ApaI (rs7975232, and TaqI (rs731236 are commonly studied in several pathologies. We aimed to evaluate the distribution of VDR BsmI, ApaI, and TaqI allele, genotype, and haplotype frequencies in an Italian cohort of 266 patients with lumbar spine disorders assessed by Magnetic Resonance Imaging and 252 asymptomatic controls. The exposure to putative risk factors was evaluated by a questionnaire. Polymorphisms were detected by PCR-RFLP and TaqMan® SNP Genotyping Assay. The results were statistically adjusted for the identified conventional risk factors. The three SNPs were in linkage disequilibrium. For all cases BbAaTT was a 3-fold risk factor OR = 3.38, whereas bbAATT (OR = 0.22, and bbaaTT (OR = 0.47 genotypes were found to be protective. Specifically, for patients affected by disc herniation only (n = 88 and all lumbar pathologies excluding stenosis and/or spondylolistesis (n = 215 B allele, Bb, Aa, and BbAaTT genotypes were risky, whereas b allele, bb, aa, and bbaaTT genotypes were protective. In patients affected by osteochondrosis with or without disc hernation (n = 50, T allele, Aa, and bbAaTT genotypes were risky, whereas t allele, AA, tt genotypes were protective. In patients affected by stenosis and/or spondylolistesis (n = 51 no significant associations were found. This is the first study showing an association of the three genetic VDR variants BsmI, ApaI, and TaqI and lumbar spine pathologies. Our study contributes to delineate genetic risk factors for specific subgroups of patients with lumbar spine pathologies highlighting the importance of haplotype analysis, and of detailed clinical evaluation of the patients for identification of genetic biomarkers.

The APA Ethical Principles as a foundational competency: application to rehabilitation psychology.

Hanson, Stephanie L; Kerkhoff, Thomas R

2011-08-01

Competence is a core component of ethical conduct as reflected in its addition as an ethical standard in the 2002 APA Ethics Code. Successfully operationalizing and assessing competence provides psychologists a means to improve education and training, advance the field of practice, and create a framework for accountability to the public. Much of the recent competency discussion has been in response to a proposed Cube Model, with its three axes being foundational competencies (practice building blocks, such as scientific knowledge, ethical standards), functional competencies (attributes of providing services, such as assessment, intervention), and developmental progression (acquiring increasing competence over the course of one's education and career). Ethics is included on the foundational competency axis and has been operationalized to the extent that subcomponents and benchmarks have been promulgated. The competency model as proposed faces multiple challenges, including gaining consensus regarding its components, addressing reliable and valid assessment over time, and creating a culture of acceptance. We propose the Ethical Principles as an alternative framework for conceptualizing ethics as a foundational competency given the Ethics Code is already time tested and includes a serial review process for broad discipline input and adaptability. We apply the Ethical Principles as foundational components to rehabilitation psychology training at internship, postdoctoral, and specialty levels to illustrate the model. Rehabilitation psychology should engage in the competency movement at the predoctoral and postdoctoral level. The application of the Ethical Principles as a foundational competency to rehabilitation psychology represents a first step in this dialog.

Entre elas encontram-se as falésias, que, por sua beleza, atraem a exploração turística o que, muitas vezes, compromete seu equilíbrio. Com a finalidade de proteger o meio ambiente das ações antrópicas, o poder público vem criando áreas para preservar e/ou conservar o meio ambiente, entre elas existem as APA e as APP. O objetivo do presente trabalho foi analisar a variabilidade espaço-temporal da linha de ruptura do relevo, na borda das falésias da APA Tambaba, entre os anos de 1985 e 2012; e identificar a existência de edificações dentro da APP no ano de 2012. Para tanto, foram utilizadas imagens do satélite Quickbird de 2012, do satélite IKONOS II de 2005 e fotos aéreas de 1985 para delimitação das linhas das falésias; o DSAS, que é uma extensão gratuita do ArcGIS, para obtenção de taxas de variação da linha de ruptura do relevo; e o software ArcGIS para delimitação e análise das APP. Como resultados, foram identificadas variações no movimento das linhas estudadas, tanto para erosão como para deposição nas falésias da APA Tambaba. No maior trecho da APA obteve-se uma média de -0,17m/ano para erosão e de 0,49m/ano para deposição, já no menor trecho a média de erosão foi -0,38m/ano e de deposição 0,14m/ano. Foi comprovada a existência de edificações irregulares correspondente a 22.818,91 m², o que equivale a aproximadamente 3% da área total da APP.

Improving the industrial production of 6-APA: enzymatic hydrolysis of penicillin G in the presence of organic solvents.

The hydrolysis of penicillin G in the presence of an organic solvent, used with the purpose of extracting it from the culture medium, may greatly simplify the industrial preparation of 6-APA. However, under these conditions, PGA immobilized onto Eupergit displays very low stability (half-life of 5 h in butanone-saturated water) and a significant degree of inhibition by the organic solvent (30%). The negative effect of the organic solvent strongly depended on the type of solvent utilized: water saturated with butanone (around 28% v/v) had a much more pronounced negative effect than that of methylisobutyl ketone (MIBK) (solubility in water was only 2%). These problems were sorted out by using a new penicillin G acylase derivative designed to work in the presence of organic solvents (with each enzyme molecule surrounded by an hydrophilic artificial environment) and a suitable organic solvent (MIBK). Using such solvent, this derivative kept its activity unaltered for 1 week at 32 degrees C. Moreover, the enzyme activity was hardly inhibited by the presence of the organic solvent. In this way, the new enzyme derivative thus prepared enables simplification of the industrial hydrolysis of penicillin G.

Section 3 of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) includes a hybrid model of personality pathology, in which dimensional personality traits are used to derive one of seven categorical personality disorder diagnoses. The Personality Inventory for DSM-5 (PID-5) was developed by the DSM-5 Personality and Personality Disorders workgroup and their consultants to produce a freely available instrument to assess the personality traits within this new system. To date, the psychometric properties of the PID-5 have been evaluated primarily in undergraduate student and community adult samples. In the current investigation, we extend this line of research to a psychiatric patient sample who participated in the APA DSM-5 Field Trial (Centre for Addiction and Mental Health site). A total of 201 psychiatric patients (102 men, 99 women) completed the PID-5 and the Revised NEO Personality Inventory (NEO PI-R). The internal consistencies of the PID-5 domain and facet trait scales were acceptable. Results supported the unidimensional structure of all trait scales but one, and the convergence between the PID-5 and analogous NEO PI-R scales. Evidence for discriminant validity was mixed. Overall, the current investigation provides support for the psychometric properties of this diagnostic instrument in psychiatric samples.

This article provides a brief overview of important issues for educators regarding medical education and technology. The literature describes key concepts, prototypical technology tools, and model programs. A work group of psychiatric educators was convened three times by phone conference to discuss the literature. Findings were presented to and input was received from the 2005 Summit on Medical Student Education by APA and the American Directors of Medical Student Education in Psychiatry. Knowledge of, skills in, and attitudes toward medical informatics are important to life-long learning and modern medical practice. A needs assessment is a starting place, since student, faculty, institution, and societal factors bear consideration. Technology needs to "fit" into a curriculum in order to facilitate learning and teaching. Learning about computers and applying computer technology to education and clinical care are key steps in computer literacy for physicians.

Culture conditions in shake flasks affect filamentous Streptomyces lividans morphology, as well the productivity and O-mannosylation of recombinant Ala-Pro-rich O-glycoprotein (known as the 45/47 kDa or APA antigen) from Mycobacterium tuberculosis. In order to scale up from previous reported shake flasks to bioreactor, data from the literature on the effect of agitation on morphology of Streptomyces strains were used to obtain gassed volumetric power input values that can be used to obtain a morphology of S. lividans in bioreactor similar to the morphology previously reported in coiled/baffled shake flasks by our group. Morphology of S. lividans was successfully scaled-up, obtaining similar mycelial sizes in both scales with diameters of 0.21 ± 0.09 mm in baffled and coiled shake flasks, and 0.15 ± 0.01 mm in the bioreactor. Moreover, the specific growth rate was successfully scaled up (0.09 ± 0.02 and 0.12 ± 0.01 h(-1), for bioreactors and flasks, respectively), and the recombinant protein productivity measured by densitometry, as well. More interestingly, the quality of the recombinant glycoprotein measured as the amount of mannoses attached to the C-terminal of APA was also scaled- up; with up to five mannose residues in cultures carried out in shake flasks; and six in the bioreactor. However, final biomass concentration was not similar, indicating that although the process can be scaled-up using the power input, others factors like oxygen transfer rate, tip speed or energy dissipation/circulation function can be an influence on bacterial metabolism.

A pesquisa se constituiu por uma análise qualitativa e exploratória a partir de entrevistas com gestores de APAEs. Os resultados obtidos indicam a predominância de práticas de contratação e demissão como modalidades de mediação dos vínculos, realizada em parceria com as prefeituras locais. A cedência de servidores pelo município, a ausência de profissionais qualificados na região pesquisada e a identificação dos trabalhadores com as demandas e características das instituições são desafios presentes nestas organizações. Diferentemente do aspecto majoritário do terceiro setor, nas instituições pesquisadas não há membros voluntários em virtude do receio de ações trabalhistas e reduzida articulação da comunidade. Observa-se que a diretoria tem participação efetiva nas decisões, em conjunto com a coordenação pedagógica, e há multifuncionalidade nos processos de trabalho em função do quadro de pessoal restrito.

The complete family of ApA phosphonate analogues with the internucleotide linkage elongated by insertion of a -CH2- group was prepared and the hybridisation and structural properties of its members in interaction with polyuridylic acid were investigated using an original 2D Raman approach. Except for the conformationally restricted ACHpA(2′3′endo-5′) modification, all of the isopolar, non-isosteric analogues form triplex-like complexes with poly(rU) at room temperature, in which two polymer strands are bound by Watson–Crick and Hoogsteen bonds to a central pseudostrand consisting of a ‘chain’ of A-dimers. For all of these dimers, the overall conformation of the triplexes was found to be similar according to their extracted Raman spectra. A simple semi-empirical model was introduced to explain the observed dependency of the efficiency of triplex formation on the adenine concentration. Apparently, for most of the modifications studied, the creation of a stable complex at room temperature requires the formation of a central pseudostrand, consisting of several adenine dimers. Molecular dynamics calculations were finally performed to interpret the differences in ‘cooperative’ behaviour between the different dimers studied. The results indicate that the exceptional properties of the ApCH2A(3′-5′) dimer could be caused by the 3D conformational compatibility of this modified linkage with the second (Hoogsteen) poly(rU) strand.

To help preserve accessory pudendal arteries (APAs) and to ensure optimal postoperative sexual function after a laparoscopic or robot-assisted radical prostatectomy, we have evaluated the incidence of APAs as detected on multidetector-row CT (MDCT) angiography and have provided a detailed anatomical description. The distribution of APAs was evaluated in 121 consecutive male patients between February 2006 and July 2007 who underwent 64- channel MDCT angiography of the lower extremities. We defined an APA as any artery located within the periprostatic region running parallel to the dorsal vascular complex. We also subclassified APAs into lateral and apical APAs. Two radiologists retrospectively evaluated the origin, course and number of APAs; the final APA subclassification based on MDCT angiography source data was determined by consensus. We identified 44 APAs in 36 of 121 patients (30%). Two distinct varieties of APAs were identified. Thirty-three APAs (75%) coursed near the anterolateral region of the prostatic apex, termed apical APAs. The remaining 11 APAs (25%) coursed along the lateral aspect of the prostate, termed lateral APAs. All APAs originated from the internal obturator artery and iliac artery or a branch of the iliac artery such as the inferior vesical artery. The majority of apical APAs arose from the internal obturator artery (84%). Seven patients (19%) had multiple APAs. APAs are more frequently detected by the use of MDCT angiography than as suggested by previous surgical studies. The identification of APAs on MDCT angiography may provide useful information for the surgical preservation of APAs during a laparoscopic or robot-assisted radical prostatectomy

Abstract We aimed to detect novel genes associated with G protein-coupled receptors (GPCRs) in aldosterone-producing adenoma (APA) and elucidate the mechanisms underlying aldosterone production. Microarray analysis targeting GPCR-associated genes was conducted using APA without known mutations (APA-WT) samples (n = 3) and APA with the KCNJ5 mutation (APA-KCNJ5; n = 3). Since gonadotropin-releasing hormone receptor (GNRHR) was the highest expression in APA-WT by microarray analysis, we investigated the effect of gonadotropin-releasing hormone (GnRH) stimulation on aldosterone production. The quantitative polymerase chain reaction assay results revealed higher GNRHR expression levels in APA-WT samples those in APA-KCNJ5 samples (P APA-WT samples, and there was a significant and positive correlation between GNRHR and LHCGR expression in all APA samples (r = 0.476, P APA-WT (n = 9), which showed higher GNRHR and LHCGR levels, had significantly higher GnRH-stimulated aldosterone response than those with APA-KCNJ5 (n = 13) (P APA-WT, and the molecular analysis including the receptor expression associated with clinical findings of GnRH stimulation.

2018-05-01

Global shortening of 3'UTRs by alternative polyadenylation (APA) has been observed in cancer cells. However, the role of APA in cancer remains unknown. CCND1 is a proto-oncogene that regulates progression through the G1-S phase of the cell cycle; moreover, it has been observed to be switching to proximal APA sites in cancer cells. To investigate the biological function of the APA of CCND1, we edited the weak poly(A) signal (PAS) of the proximal APA site to a canonical PAS using the CRISPR/Cas9 method, which can force the cells to use a proximal APA site. Cell cycle profiling and proliferation assays revealed that the proximal APA sites of CCND1 accelerated the cell cycle and promoted cell proliferation, but UTR-APA and CR-APA act via different molecular mechanisms. These results indicate that PAS editing with CRISPR/Cas9 provides a good method by which to study the biological function of APA.

Some cases of apparently idiopathic GH deficiency (GHD) may be caused by pituitary autoimmunity. To study the variations in pituitary function and antipituitary antibodies (APA) from childhood to transition age in patients with apparently idiopathic GHD. We conducted a longitudinal study. Pituitary function and APA detection by immunofluorescence were investigated in 24 childhood patients with isolated GHD before starting recombinant GH therapy and after the stopping of this therapy in transition age. Sera of patients positive for APA were processed by double immunofluorescence to identify their pituitary target. At diagnosis, 16 out of 24 patients were APA positive targeting only somatotrophs (group 1), while the remaining eight were APA negative (group 2). When retested off therapy, 12 out of 16 patients in group 1 persisted being APA positive, while the remaining four became negative with recovery of pituitary function. All patients in group 2 persisted being APA negative but still showing GHD. Of the 12 patients persistently APA positive, eight with confirmed GHD showed APA still targeting somatotrophs, whereas four showed APA targeting only gonadotrophs associated with isolated hypogonadotropic hypogonadism (HH). Patients with APA at middle but not at high titer in childhood may show a remission of autoimmune GHD in childhood after GH replacement therapy. As APA may shift their target in transition period, an early characterization of APA by double immunofluorescence is advisable in APA positive GHD patients showing delayed puberty, to allow an early diagnosis and an appropriate therapy, thus preventing the progression toward HH. © 2016 European Society of Endocrinology.

Theory of affine projection algorithms for adaptive filtering

CERN Document Server

Ozeki, Kazuhiko

2016-01-01

This book focuses on theoretical aspects of the affine projection algorithm (APA) for adaptive filtering. The APA is a natural generalization of the classical, normalized least-mean-squares (NLMS) algorithm. The book first explains how the APA evolved from the NLMS algorithm, where an affine projection view is emphasized. By looking at those adaptation algorithms from such a geometrical point of view, we can find many of the important properties of the APA, e.g., the improvement of the convergence rate over the NLMS algorithm especially for correlated input signals. After the birth of the APA in the mid-1980s, similar algorithms were put forward by other researchers independently from different perspectives. This book shows that they are variants of the APA, forming a family of APAs. Then it surveys research on the convergence behavior of the APA, where statistical analyses play important roles. It also reviews developments of techniques to reduce the computational complexity of the APA, which are important f...

2016-01-01

Alternative polyadenylation (APA), in which a transcript uses one of the poly(A) sites to define its 3′-end, is a common regulatory mechanism in eukaryotic gene expression. However, the potential of APA in determining crop agronomic traits remains elusive. This study systematically tallied poly(A) sites of 14 different rice tissues and developmental stages using the poly(A) tag sequencing (PAT-seq) approach. The results indicate significant involvement of APA in developmental and quantitative trait loci (QTL) gene expression. About 48% of all expressed genes use APA to generate transcriptomic and proteomic diversity. Some genes switch APA sites, allowing differentially expressed genes to use alternate 3′ UTRs. Interestingly, APA in mature pollen is distinct where differential expression levels of a set of poly(A) factors and different distributions of APA sites are found, indicating a unique mRNA 3′-end formation regulation during gametophyte development. Equally interesting, statistical analyses showed that QTL tends to use APA for regulation of gene expression of many agronomic traits, suggesting a potential important role of APA in rice production. These results provide thus far the most comprehensive and high-resolution resource for advanced analysis of APA in crops and shed light on how APA is associated with trait formation in eukaryotes.

The pathophysiology of aldosterone-producing adenomas (APAs) has been investigated via genetic approaches and the pathogenic significance of a series of somatic mutations, including KCNJ5 , has been uncovered. However, how the mutational status of an APA is associated with its molecular characteristics, including its transcriptome and methylome, has not been fully understood. This study was undertaken to explore the molecular characteristics of APAs, specifically focusing on APAs with KCNJ5 mutations as opposed to those without KCNJ5 mutations, by comparing their transcriptome and methylome status. Cortisol-producing adenomas (CPAs) were used as reference. We conducted transcriptome and methylome analyses of 29 APAs with KCNJ5 mutations, 8 APAs without KCNJ5 mutations and 5 CPAs. Genome-wide gene expression and CpG methylation profiles were obtained from RNA and DNA samples extracted from these 42 adrenal tumors. Cluster analysis of the transcriptome and methylome revealed molecular heterogeneity in APAs depending on their mutational status. DNA hypomethylation and gene expression changes in Wnt signaling and inflammatory response pathways were characteristic of APAs with KCNJ5 mutations. Comparisons between transcriptome data from our APAs and that from normal adrenal cortex obtained from the Gene Expression Omnibus suggested similarities between APAs with KCNJ5 mutations and zona glomerulosa. The present study, which is based on transcriptome and methylome analyses, indicates the molecular heterogeneity of APAs depends on their mutational status. Here, we report the unique characteristics of APAs with KCNJ5 mutations. © 2017 Society for Endocrinology.

Low complexity adaptive equalizers for underwater acoustic communications

Science.gov (United States)

Soflaei, Masoumeh; Azmi, Paeiz

2014-08-01

Interference signals due to scattering from surface and reflecting from bottom is one of the most important problems of reliable communications in shallow water channels. To solve this problem, one of the best suggested ways is to use adaptive equalizers. Convergence rate and misadjustment error in adaptive algorithms play important roles in adaptive equalizer performance. In this paper, affine projection algorithm (APA), selective regressor APA(SR-APA), family of selective partial update (SPU) algorithms, family of set-membership (SM) algorithms and selective partial update selective regressor APA (SPU-SR-APA) are compared with conventional algorithms such as the least mean square (LMS) in underwater acoustic communications. We apply experimental data from the Strait of Hormuz for demonstrating the efficiency of the proposed methods over shallow water channel. We observe that the values of the steady-state mean square error (MSE) of SR-APA, SPU-APA, SPU-normalized least mean square (SPU-NLMS), SPU-SR-APA, SM-APA and SM-NLMS algorithms decrease in comparison with the LMS algorithm. Also these algorithms have better convergence rates than LMS type algorithm.

We show that a membrane-associated protease, aminopeptidase A (APA), is upregulated and enzymatically active in blood vessels of human tumors. To gain mechanistic insight, we evaluated angiogenesis in APA null mice. We found that, although these mice develop normally, they fail to mount the expected angiogenic response to hypoxia or growth factors. We then isolated peptide inhibitors of APA from a peptide library and show that they specifically bind to and inhibit APA, suppress migration and proliferation of endothelial cells, inhibit angiogenesis, and home to tumor blood vessels. Finally, we successfully treated tumor-bearing mice with APA binding peptides or anti-APA blocking monoclonal antibodies. These data show that APA is a regulator of blood vessel formation, and can serve as a functional vascular target.

Full Text Available Background. Auricular point acupressure (APA is a promising treatment for pain management. Few studies have investigated the physiological mechanisms of APA analgesics. Method. In this pilot randomized clinical trial (RCT, a 4-week APA treatment was used to manage chronic low back pain (CLBP. Sixty-one participants were randomized into a real APA group (n=32 or a sham APA group (n=29. Blood samples, pain intensity, and physical function were collected at baseline and after 4 weeks of treatment. Results. Subjects in the real APA group reported a 56% reduction of pain intensity and a 26% improvement in physical function. Serum blood samples showed (1 a decrease in IL-1β, IL-2, IL-6, and calcitonin gene-related peptide [CGRP] and (2 an increase in IL-4. In contrast, subjects in the sham APA group (1 reported a 9% reduction in pain and a 2% improvement in physical function and (2 exhibited minimal changes of inflammatory cytokines and neuropeptides. Statistically significant differences in IL-4 and CGRP expression between the real and sham APA groups were verified. Conclusion. These findings suggest that APA treatment affects pain intensity through modulation of the immune system, as reflected by APA-induced changes in serum inflammatory cytokine and neuropeptide levels.

Alternative cleavage and polyadenylation (APA) plays a crucial role in the regulation of gene expression across eukaryotes. Although APA is extensively studied, its regulation within cellular compartments and its physiological impact remains largely enigmatic. Here, we used a rigorous subcellular fractionation approach to compare APA profiles of cytoplasmic and nuclear RNA fractions from human cell lines. This approach allowed us to extract APA isoforms that are subjected to differential regulation and provided us with a platform to interrogate the molecular regulatory pathways that shape APA profiles in different subcellular locations. Here, we show that APA isoforms with shorter 3' UTRs tend to be overrepresented in the cytoplasm and appear to be cell-type-specific events. Nuclear retention of longer APA isoforms occurs and is partly a result of incomplete splicing contributing to the observed cytoplasmic bias of transcripts with shorter 3' UTRs. We demonstrate that the endoribonuclease III, DICER1, contributes to the establishment of subcellular APA profiles not only by expected cytoplasmic miRNA-mediated destabilization of APA mRNA isoforms, but also by affecting polyadenylation site choice. © 2016 Neve et al.; Published by Cold Spring Harbor Laboratory Press.

Barak, Sharon; Hutzler, Yeshayahu; Dubnov-Raz, Gal

2014-05-01

The management goal of cerebral palsy (CP) is improving functionality, locomotion and independence. Treatment programs commonly encompass adapted physical activity (APA). This review summarizes the knowledge regarding the effects and recommendations for APA in persons with CP. In addition, barriers to APA in this population are reviewed. The available literature on benefits of APA to persons with CP has focused mainly on youth. The components of the APA programs generally consist of strength, aerobic and flexibility training. There is no empirical evidence that strength-training increases spasticity in people with CP. Furthermore, strength-training may increase strength and the ability to perform daily activities. Aerobic-training is especially important as persons with CP typically have low cardiorespiratory fitness and high prevalence of cardiac disease. However, limited published evidence exists on aerobic-training effects in this population. Nonetheless, the evidence suggests that aerobic-training in persons with CP can improve physiological outcomes, yet the influence of these changes on participation has not been investigated sufficiently. Stretching exercise is a common treatment for spasticity. Surprisingly, there is inconclusive evidence for the effectiveness of stretching exercise for persons with CP. Despite the importance attributed to APA for people with CP, low levels of physical activity have been reported in this population. However, when caregivers perceive greater benefits of exercise, individuals with CP are more likely to be active. In contrast, barriers to APA include costs of APA programs, limited means of transportation to APA facilities, lack of information regarding APA facilities and limited appropriate exercising equipment in the APA facilities.

Case Report: Nodule Development From Subcapsular Aldosterone-Producing Cell Clusters Causes Hyperaldosteronism.

We previously reported that the human adrenal cortex remodels to form subcapsular aldosterone-producing cell clusters (APCCs). Some APCCs were recently found to carry aldosterone-producing adenoma (APA)-associated somatic mutations in ion channel/pump genes, which implied that APCCs produce aldosterone autonomously and are an origin of APA. However, there has been no report describing an APCC-to-APA transitional lesion. A histological examination revealed unilateral multiple adrenocortical micronodules in the adrenals of two patients with primary aldosteronism (PA). Based on immunohistochemistry for aldosterone synthase, some of the micronodules were identified as possible APCC-to-APA transitional lesions (pAATLs; a tentative term used in this manuscript), which consisted of a subcapsular APCC-like portion and an inner micro-APA-like (mAPA-like) portion without an apparent histological border. Genomic DNA samples prepared from pAATL histological sections were analyzed by next-generation sequencing for the known APA-associated mutations. The mAPA-like portions from two of the three large pAATLs examined harbored mutations (KCNJ5 [p.G151R] in pAATL 3 and ATP1A1 [p.L337M] in pAATL 7), whereas their corresponding APCC-like portions did not, suggesting their role in the formation of mAPA. Another lesion carried novel mutations in ATP1A1 (p.Ile322_Ile325del and p.Ile327Ser) in both the mAPA-like and APCC-like portions, thereby supporting these portions having a clonal origin. A novel aldosterone-producing pathology, pAATL that causes unilateral PA, was detected in the adrenals of two patients. Next-generation sequencing analyses of the large pAATLs suggested that the introduction of APA-associated mutations in the ion channel/pump genes may be involved in the development of mAPA from existing APCCs.

mRNA alternative polyadenylation (APA) plays a critical role in post-transcriptional gene control and is highly regulated during development and disease. However, the regulatory mechanisms and functional consequences of APA remain poorly understood. Here, we show that an mRNA 3′ processing factor, Fip1, is essential for embryonic stem cell (ESC) self-renewal and somatic cell reprogramming. Fip1 promotes stem cell maintenance, in part, by activating the ESC-specific APA profiles to ensure the optimal expression of a specific set of genes, including critical self-renewal factors. Fip1 expression and the Fip1-dependent APA program change during ESC differentiation and are restored to an ESC-like state during somatic reprogramming. Mechanistically, we provide evidence that the specificity of Fip1-mediated APA regulation depends on multiple factors, including Fip1-RNA interactions and the distance between APA sites. Together, our data highlight the role for post-transcriptional control in stem cell self-renewal, provide mechanistic insight on APA regulation in development, and establish an important function for APA in cell fate specification.

2016-01-01

Presents the 2015 Annual Report of the American Psychological Association. In his introduction, President Barry Anton describes how 2015 was among APA's most challenging. Although 2015 ushered in an era of greater transparency within the association and enhanced communications to members and the public, it also required painful self-reflection stemming from the revelations of an independent review by an outside law firm. The review examined the question of whether APA played any role related to the Bush administration's use of abusive interrogation techniques during the war on terror. Anton's introduction also discusses (1) the APA convention, (2) representing APA at a White House meeting with health care providers and insurance companies, (3) APA's effort to increase the number of APA-accredited internships, (4) international activities, and (5) the global summit on psychology and integrated care.

Single Nucleotide Polymorphisms Can Create Alternative Polyadenylation Signals and Affect Gene Expression through Loss of MicroRNA-Regulation

Science.gov (United States)

Thomas, Laurent F.; Sætrom, Pål

2012-01-01

Alternative polyadenylation (APA) can for example occur when a protein-coding gene has several polyadenylation (polyA) signals in its last exon, resulting in messenger RNAs (mRNAs) with different 3′ untranslated region (UTR) lengths. Different 3′UTR lengths can give different microRNA (miRNA) regulation such that shortened transcripts have increased expression. The APA process is part of human cells' natural regulatory processes, but APA also seems to play an important role in many human diseases. Although altered APA in disease can have many causes, we reasoned that mutations in DNA elements that are important for the polyA process, such as the polyA signal and the downstream GU-rich region, can be one important mechanism. To test this hypothesis, we identified single nucleotide polymorphisms (SNPs) that can create or disrupt APA signals (APA-SNPs). By using a data-integrative approach, we show that APA-SNPs can affect 3′UTR length, miRNA regulation, and mRNA expression—both between homozygote individuals and within heterozygote individuals. Furthermore, we show that a significant fraction of the alleles that cause APA are strongly and positively linked with alleles found by genome-wide studies to be associated with disease. Our results confirm that APA-SNPs can give altered gene regulation and that APA alleles that give shortened transcripts and increased gene expression can be important hereditary causes for disease.

Full Text Available Aminopeptidase A (APA cleaves angiotensin (Ang II, kallidin, and other related peptides. In the brain, it activates the renin angiotensin system and causes hypertension. Limited data are available on the dipsogenic effect of APA and pressor effect of degraded peptides of APA such as bradykinin. Wistar-Kyoto rats received intracerebroventricular (icv APA in a conscious, unrestrained state after pretreatment with (i vehicle, (ii 80 μg of telmisartan, an Ang II type-1 (AT1 receptor blocker, (iii 800 nmol of amastatin, an aminopeptidase inhibitor, and (iv 1 nmol of HOE-140, a bradykinin B2 receptor blocker. Icv administration of 400 and 800 ng of APA increased blood pressure by 12.6 ± 3.0 and 19.0 ± 3.1 mmHg, respectively. APA did not evoke drinking behavior. Pressor response to APA was attenuated on pretreatment with telmisartan (vehicle: 22.1 ± 2.2 mmHg versus telmisartan: 10.4 ± 3.2 mmHg. Pressor response to APA was also attenuated with amastatin and HOE-140 (vehicle: 26.5 ± 1.1 mmHg, amastatin: 14.4 ± 4.2 mmHg, HOE-140: 16.4 ± 2.2 mmHg. In conclusion, APA increase in the brain evokes a pressor response via enzymatic activity without dipsogenic effect. AT1 receptors and B2 receptors in the brain may contribute to the APA-induced pressor response.

Aminopeptidase A (APA) is expressed in glomerular podocytes and tubular epithelia and metabolizes angiotensin II (AngII), a peptide known to promote glomerulosclerosis. In this study, we tested whether APA expression changes in response to progressive nephron loss or whether APA exerts a protective role against glomerular damage and during AngII-mediated hypertensive kidney injury. At advanced stages of FSGS, fawn-hooded hypertensive rat kidneys exhibited distinctly increased APA staining in areas of intact glomerular capillary loops. Moreover, BALB/c APA-knockout (KO) mice injected with a nephrotoxic serum showed persistent glomerular hyalinosis and albuminuria 96 hours after injection, whereas wild-type controls achieved virtually full recovery. We then tested the effect of 4-week infusion of AngII (400 ng/kg per minute) in APA-KO and wild-type mice. Although we observed no significant difference in achieved systolic BP, AngII-treated APA-KO mice developed a significant rise in albuminuria not observed in AngII-treated wild-type mice along with increased segmental and global sclerosis and/or collapse of juxtamedullary glomeruli, microcystic tubular dilation, and tubulointerstitial fibrosis. In parallel, AngII treatment significantly increased the kidney AngII content and attenuated the expression of podocyte nephrin in APA-KO mice but not in wild-type controls. These data show that deficiency of APA increases susceptibility to glomerular injury in BALB/c mice. The augmented AngII-mediated kidney injury observed in association with increased intrarenal AngII accumulation in the absence of APA suggests a protective metabolizing role of APA in AngII-mediated glomerular diseases.

Full Text Available Antiphospholipid antibodies (APA are associated with thrombosis, thrombocytopenia and fetal loss but they occur in a variety of diseases. Despite many efforts, a correlation between the specificity of particular subgroups of APA and particular clinical situations remains to be established. The antigens at the origin of APA remain to be identified. We discuss here the possible links between cell apoptosis or necrosis, leading to plasma membrane alterations, and the occurrence of APA in response to sustained stimulation. The pathogenic potential of APA is also considered with respect to recurrent pregnancy loss.

Sparse Adaptive Channel Estimation Based on lp-Norm-Penalized Affine Projection Algorithm

Directory of Open Access Journals (Sweden)

Yingsong Li

2014-01-01

Full Text Available We propose an lp-norm-penalized affine projection algorithm (LP-APA for broadband multipath adaptive channel estimations. The proposed LP-APA is realized by incorporating an lp-norm into the cost function of the conventional affine projection algorithm (APA to exploit the sparsity property of the broadband wireless multipath channel, by which the convergence speed and steady-state performance of the APA are significantly improved. The implementation of the LP-APA is equivalent to adding a zero attractor to its iterations. The simulation results, which are obtained from a sparse channel estimation, demonstrate that the proposed LP-APA can efficiently improve channel estimation performance in terms of both the convergence speed and steady-state performance when the channel is exactly sparse.

Independence of scientific publishing. Reaffirming the principle.

Science.gov (United States)

Bjork, R A

2000-09-01

Historically, the American Psychological Association (APA), as part of its contract with the editors of APA journals, has granted to the editors sole responsibility to accept or reject manuscripts for publication, without such actions being open for review by APA. Such a policy fosters the freedom of inquiry and expression so necessary for a healthy science. It also serves to protect the Association because publication of an article in an APA journal does not represent endorsement by APA itself. The lessons of history are clear: When political or other pressures interfere with the autonomy of science, the societal and scientific consequences are grim. APA should reaffirm the principle that a healthy science of psychology requires an open exchange of ideas and findings.

Dynamic Analyses of Alternative Polyadenylation from RNA-Seq Reveal 3′-UTR Landscape Across 7 Tumor Types

Science.gov (United States)

Xia, Zheng; Donehower, Lawrence A; Cooper, Thomas A.; Neilson, Joel R.; Wheeler, David A.; Wagner, Eric J.; Li, Wei

2015-01-01

Alternative polyadenylation (APA) is a pervasive mechanism in the regulation of most human genes, and its implication in diseases including cancer is only beginning to be appreciated. Since conventional APA profiling has not been widely adopted, global cancer APA studies are very limited. Here we develop a novel bioinformatics algorithm (DaPars) for the de novo identification of dynamic APAs from standard RNA-seq. When applied to 358 TCGA Pan-Cancer tumor/normal pairs across 7 tumor types, DaPars reveals 1,346 genes with recurrent and tumor-specific APAs. Most APA genes (91%) have shorter 3′ UTRs in tumors that can avoid miRNA-mediated repression, including glutaminase (GLS), a key metabolic enzyme for tumor proliferation. Interestingly, selected APA events add strong prognostic power beyond common clinical and molecular variables, suggesting their potential as novel prognostic biomarkers. Finally, our results implicate CstF64, an essential polyadenylation factor, as a master regulator of 3′ UTR shortening across multiple tumor types. PMID:25409906

Adaptive Equalizer Using Selective Partial Update Algorithm and Selective Regressor Affine Projection Algorithm over Shallow Water Acoustic Channels

2014-01-01

Full Text Available One of the most important problems of reliable communications in shallow water channels is intersymbol interference (ISI which is due to scattering from surface and reflecting from bottom. Using adaptive equalizers in receiver is one of the best suggested ways for overcoming this problem. In this paper, we apply the family of selective regressor affine projection algorithms (SR-APA and the family of selective partial update APA (SPU-APA which have low computational complexity that is one of the important factors that influences adaptive equalizer performance. We apply experimental data from Strait of Hormuz for examining the efficiency of the proposed methods over shallow water channel. We observe that the values of the steady-state mean square error (MSE of SR-APA and SPU-APA decrease by 5.8 (dB and 5.5 (dB, respectively, in comparison with least mean square (LMS algorithm. Also the families of SPU-APA and SR-APA have better convergence speed than LMS type algorithm.

Biaxial and antiferroelectric structure of the orthogonal smectic phase of a bent-shaped molecule and helical structure in a chiral mixture system

Science.gov (United States)

Kang, Sungmin; Nguyen, Ha; Nakajima, Shunpei; Tokita, Masatoshi; Watanabe, Junji

2013-05-01

We examined the biaxial and antiferroelectric properties in the Smectic-APA (Sm-APA) phase of bent-shaped DC-S-8. The biaxiality, which results from the existence of a secondary director, was well established from birefringence observations in the homeotropically aligned Sm-APA. By entering into Sm-APA phase, the birefringence (Δn, difference between two refractive indices of short axes) continuously increased from 0 to 0.02 with decreasing temperature. The antiferroelectric switching and second harmonic generation (SHG) activity on the field-on state were also observed in the Sm-APA phase, and the evaluated spontaneous polarization (PS) value strongly depended on temperature. The temperature dependence of Δn and PS resembles each other and follows Haller's approximation, showing that the biaxiality is due to polar packing in which the molecules are preferentially packed with their bent direction arranged in the same direction, and that the phase transition of Sm-APA to Sm-A is second order. The biaxiality was further examined in chiral Sm-APA*. Doping with chiral components induced the helical twisting of the secondary director in the Sm-APA* phase, which was confirmed by observing the reflection of the circular dichroism (CD) bands in the homeotropically aligned cell. The helical pitch of Sm-APA* is tunable in the range of 300-700 nm wavelength with a variation in the chiral content of 5 to 10 weight (wt)%.

The Hoffman Report (Hoffman et al., 2015) documented devastating information about the American Psychological Association (APA) and the profession of psychology in the United States, prompting a public apology and a formal commitment by APA to correct its mistakes (APA, 2015). In the current article, we utilize betrayal trauma theory (Freyd, 1997), including betrayal blindness (e.g., Freyd, 1996; Tang, 2015) and institutional betrayal (Smith & Freyd, 2014b), to understand and learn from APA's behaviors. We further situate this discussion in the context of inequality, both within APA and in American society generally. We detail how the impact of APA's institutional betrayals extended beyond the organization, its members, and the psychology profession, highlighting the potential for disproportionate harm to minorities, including those who were tortured; Muslims, Middle Easterners, Afghans, and non-Americans who were not tortured; and other minority individuals (Gómez, 2015d). Acknowledging, understanding, and addressing its institutional betrayals offers APA the opportunity to take meaningful corrective and preventive measures. We propose several institutional reparations, including making concrete changes with transparency and conducting self-assessments to inform further needed changes (Freyd & Birrell, 2013). By engaging in institutional courage, APA has the potential to grow into an ethical governing body that fulfills its mission to "advance the creation, communication and application of psychological knowledge to benefit society and improve people's lives" (APA, 2016).

Context: Primary aldosteronism is a heterogeneous disease that includes both sporadic and familial forms. A point mutation in the KCNJ5 gene is responsible for familial hyperaldosteronism type III. Somatic mutations in KCNJ5 also occur in sporadic aldosterone producing adenomas (APA). Objective: The objective of the study was to define the effect of the KCNJ5 mutations on gene expression and aldosterone production using APA tissue and human adrenocortical cells. Methods: A microarray analysis was used to compare the transcriptome profiles of female-derived APA samples with and without KCNJ5 mutations and HAC15 adrenal cells overexpressing either mutated or wild-type KCNJ5. Real-time PCR validated a set of differentially expressed genes. Immunohistochemical staining localized the KCNJ5 expression in normal adrenals and APA. Results: We report a 38% (18 of 47) prevalence of KCNJ5 mutations in APA. KCNJ5 immunostaining was highest in the zona glomerulosa of NA and heterogeneous in APA tissue, and KCNJ5 mRNA was 4-fold higher in APA compared with normal adrenals (P APA with and without KCNJ5 mutations displayed slightly different gene expression patterns, notably the aldosterone synthase gene (CYP11B2) was more highly expressed in APA with KCNJ5 mutations. Overexpression of KCNJ5 mutations in HAC15 increased aldosterone production and altered expression of 36 genes by greater than 2.5-fold (P APA, and our data suggest that these mutations increase expression of CYP11B2 and NR4A2, thus increasing aldosterone production.

The AP Advance (APA) is a videolaryngoscope with interchangeable blades: intubators can choose standard Macintosh blades or a difficult-airway blade with increased curvature and a channel to guide the tube to the larynx. The APA may therefore be comparably effective in both normal and difficult airways. We tested the hypotheses that intubation with the APA is no slower than Macintosh laryngoscopy for normal mannequin airways, and that it is no slower than videolaryngoscopy using a GlideScope Ranger in difficult mannequin airways. Medical professionals whose roles potentially include tracheal intubation were trained with each device. Participants intubated simulated (Laerdal SimMan) normal and difficult airways with the APA, GlideScope, and a conventional Macintosh blade. Speed of intubation was compared using Cox proportional hazards regression, with a hazard ratio >0.8 considered noninferior. We also compared laryngeal visualization, failures, and participant preferences. Unadjusted intubation times in the normal airway with the APA and Macintosh were virtually identical (median, 22 vs 23 seconds); after adjustment for effects of experience, order, and period, the hazard ratio (95% confidence interval) comparing APA with Macintosh laryngoscopy was 0.87 (0.65, 1.17), which was not significantly more than our predefined noninferiority boundary of 0.8 (P = 0.26). Intubation with the APA was faster than with the GlideScope in difficult airways (hazard ratio = 7.6 [5.0, 11.3], P APA, whereas 33% and 37% failed with the GlideScope and Macintosh, respectively. In the difficult airway, 99% of participants achieved a Cormack and Lehane grade I to II view with the APA, versus 85% and 33% with the GlideScope and Macintosh, respectively. When asked to choose 1 device overall, 82% chose the APA. Intubation times were similar with the APA and Macintosh laryngoscopes in mannequins with normal airways. However, intubation with the APA was significantly faster than with the Glide

Full Text Available This paper addresses the social and environmental conflicts in a protected landscape of sustainable use which has faced urban expansion of high social exclusion. In this scenario of both socio and environmental vulnerability, the Protected Landscape of Borore-Colonia was created, at the same time that municipal natural parks in the interior of this APA were also created as compensatory measure for the environmental licensing of the South Part of the Metropolitan Ring Road. The research question that guided the study is: What are the interference of environmental licensing of the Metropolitan Ring Road both in existing conflicts and in the generation new conflicts in the implementation of the Municipal Natural Park Itaim in the region of Borore-Colonia Protected Landscape? The objetive of this study was to analyze the conflicts in the Protected Landscape of Borore-Colonia considering both the pre-existing conflicts to the environmental licensing of the Southern Ring Road stretch and the conflicts that emerged with the creation of the park as a compensatory measure of this licensing. This research was developed as a case study having documental analysis, semi-structured interview carried out with nine social actors, and participatory research as major sources of information. The ethnographic perspective was the selected one for the conflict analysis. As a result, both socio and environmental conflicts that took place previously and simultaneously to the environmental licensing of the South Part of the Metropolitan Ring Road were analyzed with identification of the natural and social agents involved, the major actors (including the Public Power, and their power of quotas. As a conclusion, it was perceived that the pre-existing conflicts were accentuated by the new ones resulting from the licensing and the environmental impacts of the construction of the Southern Section of the Ring Road and the conduct of the Bill of the creation of the protected

Full Text Available Introduction : Despite increasing use of antiplatelet agents (APA, little is known regarding the effect of these agents on the orthopedic trauma patient. This study reviews clinical outcomes of patients with pelvic fractures (Pfx who were using pre-injury APA. Specifically, we focused on the influence of APA on postinjury bleeding, transfusions, and outcomes after Pfx. Methods : Patients with Pfx admitted during a 37-month period beginning January 2006 were divided into APA and non-APA groups. Pelvic injuries were graded using pelvic fracture severity score (PFSS-a combination of Young-Burgess (pelvic ring, Letournel-Judet (acetabular, and Denis (sacral fracture classifications. Other clinical data included demographics, co-morbid conditions, medications, injury severity score (ISS, associated injuries, morbidity/mortality, hemoglobin trends, blood product use, imaging studies, procedures, and resource utilization. Multivariate analyses for predictors of early/late transfusions, pelvic surgery, and mortality were performed. Results : A total of 109 patients >45 years with Pfx were identified, with 37 using preinjury APA (29 on aspirin [ASA], 8 on clopidogrel, 5 on high-dose/scheduled non-steroidal anti-inflammatory agents [NSAID], and 8 using >1 APAs. Patients in the APA groups were older than patients in the non-APA group (70 vs. 63 years, P < 0.01. The two groups were similar in gender distribution, PFSS and ISS. Patients in the APA group had more comorbidities, lower hemoglobin levels at 24 h, and received more packed red blood cell (PRBC transfusions during the first 24 h of hospitalization (all, P < 0.05. There were no differences in platelet or late (>24 h PRBC transfusions, blood loss/transfusions during pelvic surgery, lengths of stay, post-ED/discharge disposition, or mortality. In multivariate analysis, predictors of early PRBC transfusion included higher ISS/PFSS, pre-injury ASA use, and lower admission hemoglobin (all, P < 0

Data on calcium carboorthovanadate, Ca 10 (VO 4 ) 6 CO 3 , a new compound with an appatite structure based on calcium orthovanadate, are reported. The synthesis has been conducted in a stoichiometric mixture of finely ground calcium carbonate and calcium orthovanadate. It is found that calcium carboorthovanadate belongs to the hexagonal syngony and has an apatite structure. An analysis of the infrared spectra of initial compounds and calcium carboorthovanadate confirmed the presence of carbonate (CO 3 ) 2- and orthovanadate (VO 4 ) 3 groupings in the latter. On heating in air, beginning with 450 deg C calcium carboorthovanadate decomposes at a slow rate into calcium oxide, calcium orthovanadate, and carbon dioxide

Increasing phytoplankton-available phosphorus and inhibition of macrophyte on phytoplankton bloom.

Science.gov (United States)

Dai, Yanran; Wu, Juan; Ma, Xiaohang; Zhong, Fei; Cui, Naxin; Cheng, Shuiping

2017-02-01

We assembled mesocosms to address the coherent mechanisms that an increasing phosphorus (P) concentration in water columns coupled with the phytoplankton bloom and identify the performance gap of regulating phytoplankton growth between two macrophyte species, Ceratophyllum demersum L. and Vallisneria spiralis L. Intense alkaline phosphatase activities (APA) were observed in the unplanted control, with their predominant part, phytoplankton APA (accounting for up to 44.7% of the total APA), and another large share, bacterial APA. These correspond with the large average concentration of total phosphorus (TP), total dissolved phosphorus (TDP) and soluble reactive (SRP) as well as high phytoplankton density in the water column. The consistency among P concentrations, phytoplankton density and APA, together with the positive impact of phytoplankton density on total APA revealed by the structural equation modelling (SEM), indicates that facilitated APA levels in water is an essential strategy for phytoplankton to enhance the available P. Furthermore, a positive interaction between phytoplankton APA and bacteria APA was detected, suggesting a potential collaboration between phytoplankton and bacteria to boost available P content in the water column. Both macrophyte species had a prominent performance on regulating phytoplankton proliferation. The phytoplankton density and quantum yield in C. demersum systems were all significantly lower (33.8% and 24.0%) than those in V. spiralis systems. Additionally, a greater decoupling effect of C. demersum on the relationship between P, APA, phytoplankton density, bacteria dynamic and quantum yield was revealed by SEM. These results imply that the preferred tactic of different species could lead to the performance gap. Copyright © 2016 Elsevier B.V. All rights reserved.

Auricular point acupressure as an adjunct analgesic treatment for cancer patients: a feasibility study.

Yeh, Chao Hsing; Chien, Lung-Chang; Chiang, Yi Chien; Ren, Dianxu; Suen, Lorna Kwai-Ping

2015-06-01

This study aimed (1) to examine the feasibility of an auricular point acupressure (APA) research protocol in terms of recruitment and for the assessment and management of pain and (2) to examine the potential APA analgesic effects for cancer patients. This study was a repeated-measures one-group design. Participants were recruited from the cancer center follow-up clinic affiliated with a large university hospital in the northeastern United States. Participants included 50 patients aged 55-87 years with a diagnosis of cancer. Participants received 7 days of APA treatment for their pain. After appropriate acupoints were identified, vaccaria seeds were carefully taped onto each selected auricular point on each ear. The study recruitment and retention rates were 92% and 91%, respectively. Importantly, the study found preliminary evidence for the analgesic effects of APA for cancer pain management. For example, by the end of the 7-day study, APA reduced pain intensity more than 55% for "worst pain" and about 57% for "average pain" and "pain intensity." Moreover, the use of pain medication was reduced during the APA treatment (e.g., 78% of patients [n = 39] took less pain medication than before the treatment). APA appears to be highly acceptable to patients with cancer-related pain. However, without a placebo control, we cannot draw conclusive evidence for the analgesic effect of APA for cancer patients. A sham group must be added to future studies to differentiate the true effects of APA from the possible psychological effects of the APA treatment.

Immunohistochemical characteristics of atypical polypoid adenomyoma with special reference to h-caldesmon.

Science.gov (United States)

Horita, Ayako; Kurata, Atsushi; Maeda, Daichi; Fukayama, Masashi; Sakamoto, Atsuhiko

2011-01-01

Atypical polypoid adenomyoma (APA) is a relatively rare benign uterine tumor, histologically characterized by proliferation of irregular endometrioid glands accompanied by stromal cells of smooth muscle origin. As the epithelial components of APA usually show cytological atypia, a differential diagnosis between this tumor and endometrioid carcinoma invading myometrium is often difficult, especially in curettage material. This distinction is clinically very important to avoid unnecessary hysterectomy. However, only a few immunohistochemical studies of APA that differentiate it from malignancy have been published. Therefore, we have investigated the expression of several antigens in APA and compared them with those present in myoinvasive carcinoma. Six specimens of APA were studied, along with controls of endometrioid carcinoma invading myometrium. Antibodies to p53, Ki-67, CD10, and h-caldesmon reacted positively using immunohistochemistry. Variable positive expressions of p53 and Ki-67 were observed in both epithelial and stromal components of APA, and in myoinvasive endometrioid carcinoma. CD10 was negative or partially and weakly positive whereas h-caldesmon was completely negative in the stromal cells of all 6 specimens of APA. However, in the myometrium in which endometrioid carcinoma invaded, a fringe-like positive staining pattern was occasionally observed for CD10, whereas a diffuse positive signal was obtained for h-caldesmon. The results of this study indicate that immunohistochemically, p53, and Ki-67 are not reliable markers but that h-caldesmon is useful in distinguishing APA from myoinvasive endometrioid carcinoma. Further, our data suggest that the stromal cells of APA are mainly immature smooth muscle cells, and thus APA may be a mixed tumor.

DHEA, DHEAS and PCOS.

Science.gov (United States)

Goodarzi, Mark O; Carmina, Enrico; Azziz, Ricardo

2015-01-01

Approximately 20-30% of PCOS women demonstrate excess adrenal precursor androgen (APA) production, primarily using DHEAS as a marker of APA in general and more specifically DHEA, synthesis. The role of APA excess in determining or causing PCOS is unclear, although observations in patients with inherited APA excess (e.g., patients with 21-hydroxylase deficient congenital classic or non-classic adrenal hyperplasia) demonstrate that APA excess can result in a PCOS-like phenotype. Inherited defects of the enzymes responsible for steroid biosynthesis, or defects in cortisol metabolism, account for only a very small fraction of women suffering from hyperandrogenism or APA excess. Rather, women with PCOS and APA excess appear to have a generalized exaggeration in adrenal steroidogenesis in response to ACTH stimulation, although they do not have an overt hypothalamic-pituitary-adrenal axis dysfunction. In general, extra-adrenal factors, including obesity, insulin and glucose levels, and ovarian secretions, play a limited role in the increased APA production observed in PCOS. Substantial heritabilities of APAs, particularly DHEAS, have been found in the general population and in women with PCOS; however, the handful of SNPs discovered to date account only for a small portion of the inheritance of these traits. Paradoxically, and as in men, elevated levels of DHEAS appear to be protective against cardiovascular risk in women, although the role of DHEAS in modulating this risk in women with PCOS remains unknown. In summary, the exact cause of APA excess in PCOS remains unclear, although it may reflect a generalized and inherited exaggeration in androgen biosynthesis of an inherited nature.

2013-01-01

Full Text Available Objectives. This prospective, randomized clinical trial (RCT was designed to investigate the feasibility and effects of a 4-week auricular point acupressure (APA for chronic low back pain (CLBP. Methods. Participants were randomized to either true APA (true acupoints with taped seeds on the designated ear points for CLBP or sham APA (sham acupoints with taped seeds but on different locations than those designated for CLBP. The duration of treatment was four weeks. Participants were assessed before treatment, weekly during treatment, and 1 month following treatment. Results. Participants in the true APA group who completed the 4-week APA treatment had a 70% reduction in worst pain intensity, a 75% reduction in overall pain intensity, and a 42% improvement in disability due to back pain from baseline assessment. The reductions of worst pain and overall pain intensity in the true APA group were statistically greater than participants in the sham group (P<0.01 at the completion of a 4-week APA and 1 month followup. Discussion. The preliminary findings of this feasibility study showed a reduction in pain intensity and improvement in physical function suggesting that APA may be a promising treatment for patients with CLBP.

Variations of alkaline phosphatase activity and P fractions in sediments of a shallow Chinese eutrophic lake (Lake Taihu)

2007-01-01

The distribution of alkaline phosphatase activity (APA) and P fractions in sediment cores and the relationship between them were studied in a shallow Chinese freshwater lake (Lake Taihu). Sediment cores were collected from four sites, characterized by different degrees of eutrophication in June 2004. Sediment P was fractionated into Fe/Al-P, Ca-P, organic P (OP), inorganic P (IP) and total P (TP). The former two species made the largest contribution to the sediment P pool. Results show that trophic status and hydrological conditions have great impact on the APA of the sediments. The order of the APA in sediments was conjectured to be: macrophyte dominated lake > transitional lake > algal dominated lake. APA profiles follow a similar downcore decreasing trend. There was a positive relationship between the APA and the TP, IP. The multiple linear regression equation of the APA and P fractions is: APA = -97 + 0.768TP - 0.985Fe/Al-P. - Characteristics of the alkaline phosphatase activity and P fractions in sediments of different trophic status lake were studied in Lake Taihu

Takeda, R; Matsubara, T; Miyamori, I; Hatakeyama, H; Morise, T

1995-05-01

The incidence of vascular complications in 224 patients with aldosterone-producing adenoma (APA) which was proven on adrenal surgery, was compared to that in 224 sex- and age-matched patients with essential hypertension (EHT). The incidence of cerebral hemorrhage was significantly higher (p < 0.05) in the patients with APA when compared to the EHT group. On the other hand, the incidence of myocardial infarction and/or congestive heart failure in the APA group was lower, although this difference did not reach statistical significance. Diastolic blood pressure in the APA group was significantly higher (p < 0.001) in the EHT group. However, a significant difference in diastolic blood pressure was not detected between the APA groups with and without vascular complications, whereas in the EHT group diastolic blood pressure was significantly higher (p < 0.001) in cases with vascular complications as compared to those without complications. As a possible factor contributing to the higher incidence of cerebral hemorrhage in the APA group, proteinuria was suggested. It was recommended that patients with primary aldosteronism should undergo operation when localization of the APA is established.

2005-09-01

For this study, the authors analyzed the contents of 16 psychology journals for the presence of empirical articles on African Americans, Latinos, Asians, and Native Americans during the period ranging from 1990 to 1999. In 6 APA journals, there was a low percentage (4.7%) of such articles. African Americans were the most studied ethnic group. Data collected for this study also indicated that minority research has been increasing more in non-APA journals than in APA journals. In both APA and non-APA journals, counseling-oriented journals had higher percentages of minority articles than did journals of other subdisciplines. Possible explanations, consequences, and suggestions for future research are discussed.

Presence and patterns of alkaline phosphatase activity and phosphorus cycling in natural riparian zones under changing nutrient conditions

Directory of Open Access Journals (Sweden)

Peifang Wang

2014-08-01

Full Text Available Phosphorus (P is an important limiting nutrient in aquatic ecosystems and knowledge of P cycling is fundamental for reducing harmful algae blooms and other negative effects in water. Despite their importance, the characteristics of P cycling under changing nutrient conditions in shallow lakes were poorly investigated. In this study, in situ incubation experiments were conducted in a natural riparian zone in the main diversion channel used for water transfer into Lake Taihu (Wangyu River. Variations in microbial biomass, dissolved P fractions (organic and inorganic, and alkaline phosphatase activity (bulk APA and specific APA were determined after incubation with and without the addition of P and nitrogen (N (4 total water treatments: +P, +N, +NP, and control. Experiments were conducted during two seasons (late spring and early fall to account for natural differences in nutrient levels that may occur in situ. Our results demonstrated that low levels of DRP may not necessarily indicate P limitation. Phytoplankton exhibited “serial N limitation with P stress” in May, such that chlorophyll a (Chl a increased significantly with N addition, while the limiting nutrient shifted to P in October and phytoplankton biomass increased with P addition. Phytoplankton contributed greatly to APA production and was significantly influenced by P bioavailability, yet high levels of bulk APA were also not necessarily indicative of P limitation. In contrast to phytoplankton, bacteria were less P stressed. As a consequence of enhanced utilization of dissolved reactive P (DRP and dissolved organic P (DOP, +N treatment elevated APA significantly. By contrast, APA could be repressed to low values and phytoplankton converted a large portion of DRP to DOP with P addition. But this was not consistent with bacteria APA (bact-APA in the absence or presence of abundant phytoplankton biomass. The correlation between bulk APA and DRP was good at separate sites and discrepant

Are Hypometric Anticipatory Postural Adjustments Contributing to Freezing of Gait in Parkinson’s Disease?

2018-02-01

Full Text Available Introduction: This study aims at investigating whether impaired anticipatory postural adjustments (APA during gait initiation contribute to the occurrence of freezing of gait (FOG or whether altered APAs compensate for FOG in Parkinson’s disease (PD.Methods: Gait initiation after 30 s quiet stance was analyzed without and with a cognitive dual task (DT in 33 PD subjects with FOG (PD+FOG, 30 PD subjects without FOG (PD-FOG, and 32 healthy controls (HC. APAs were characterized with inertial sensors and muscle activity of the tensor fasciae latae (TFL, gastrocnemius, and tibialis anterior was captured with electromyography recordings. Nine trials (of 190 were associated with start hesitation/FOG and analyzed separately.Results: PD+FOG and PD-FOG did not differ in disease duration, disease severity, age, or gender. PD+FOG had significantly smaller medio-lateral (ML and anterio-posterior APAs compared to PD-FOG (DT, p < 0.05. PD+FOG had more co-contraction of left and right TFL during APAs compared to PD-FOG (p < 0.01. Within the PD+FOG, the ML size of APA (DT was positively correlated with the severity of FOG history (NFOG-Q, with larger APAs associated with worse FOG (rho = 0.477, p = 0.025. ML APAs were larger during trials with observed FOG compared to trials of PD+FOG without FOG.Conclusions: People with PD who have a history of FOG have smaller ML APAs (weight shifting during gait initiation compared to PD-FOG and HC. However, start hesitation (FOG is not caused by an inability to sufficiently displace the center of mass toward the stance leg because APAs were larger during trials with observed FOG. We speculate that reducing the acceleration of the body center of mass with hip abductor co-contraction for APAs might be a compensatory strategy in PD+FOG, to address postural control deficits and enable step initiation.

Alkaline Phosphatase Activity : an overlooked player on the phosphate behavior in macrotidal estuaries

Science.gov (United States)

Delmas, Daniel; Labry, Claire; Youenou, Agnes; Quere, Julien; Auguet, Jean Christophe; Montanie, Helene

2014-05-01

The non-conservative behavior of phosphate within the estuarine salinity gradient is essentially assigned to physico-chemical processes, such as desorption at low salinity and to benthic exchanges. Microbial phosphatase activity (APA), generally related to phosphate deficiency, is seldom studied in phosphate rich estuarine waters. In order to address the impact of microbial activity (bacterial abundance, production BSP, APA) on phosphate behavior, we studied these activities on a seasonal basis within the salinity gradient of two macrotidal estuaries presenting different levels of suspended solids. Whatever the season the Charente estuary is characterized by high levels of Suspended Particulate Matter (SPM > 1g.L-1), particularly in the Maximum Turbidity Zone (MTZ) located at the 5-10 psu. In this area characterized by high BSP and APA there is a significant increase of PO4 levels especially during summer. In the Aulne estuary the particle load is significantly lower (1/10) but high BSP and APA are equally recorded. In the highly turbid waters of the Charente estuary, active phytoplankton is virtually absent as pheopigments constitute up to 80% of the total pigments, particularly in the MTZ, therefore APA may essentially have a bacterial origin. In the Aulne estuary attached bacteria are dominant, both in numbers and production, and their distribution along the haline gradient perfectly follows those of APA and phosphate levels. These observations, associated with the very close relationships observed between APA, SPM and BSP, suggest that APA derive mainly from bacterial (attached) origin and operate at the expense of particulate phosphorus and hence contribute to PO4 regeneration, especially in spring and summer. Finally, as APA increased as PO4, whereas the reverse is observed in both fresh and marine waters, an original scheme for APA regulation, related to the large dominance of attached bacteria can be described for the estuarine waters.

Primary aldosteronism could exert a negative feedback on prorenin secretion, of possibly different magnitude, whether it is related to an aldosterone-producing adenoma (APA) or an idiopathic hyperaldosteronism (IHA). The objectives of this study were to evaluate the level of prorenin in three subgroups: APA, IHA, and essential hypertension; and the performance of the aldosterone-to-prorenin ratio (APR) for the diagnosis of an APA. Seven hundred and forty-six hypertensive patients with a standardized work-up, including a prorenin measurement, were considered. Ninety-six patients without neutral treatment and 38 patients with other forms of secondary hypertension were excluded. APA and IHA were categorized according to computed tomography scan, adrenal venous sampling, pathological analysis and improvement of hypertension after surgery. Thirty-five patients had a diagnosis of APA, 57 of IHA and 504 of essential hypertension. Prorenin was lower in APA and IHA than in essential hypertension (32.9, 40.4 and 50.3  pg/ml, respectively; P < 0.001). APR was higher in patients with APA and IHA than in those with essential hypertension (24.0, 11.8, and 4.0  pmol/l per pg/ml, respectively; P < 0.001). The APR was more discriminant than the aldosterone-to-renin ratio to identify APA compared to IHA (area under the receiver operating curve at 0.750 and 0.639, respectively; P = 0.04). The optimal cut-off values were 22  pmol/l per pg/ml for APR (sensitivity 57.0%, specificity 93.0%) and 440  pmol/l per pg/ml for aldosterone-to-renin ratio (sensitivity 54.3%, specificity 82.5%). Primary aldosteronism and particularly its most caricatural form, that is APA, seems associated with a lower level of prorenin than essential hypertension. The APR could be included in the diagnostic strategy of APA.

Detection of antipituitary antibodies (APA) at high levels and with a particular immunofluorescence pattern in patients with autoimmune polyendocrine syndromes may indicate a possible future autoimmune pituitary involvement. This longitudinal study was aimed at characterizing in patients with a single organ-specific autoimmune disease the pituitary cells targeted by APA at start, verifying whether this characterization allows to foresee the kind of possible subsequent hypopituitarism. Thirty-six APA positive and 40 APA negative patients with isolated autoimmune diseases participated in the study. None of them had pituitary dysfunction at entry. Characterization by four-layer immunofluorescence of pituitary cells targeted by APA in APA positive patients at entry and study of pituitary function in all patients were performed every 6 months during a 5 year follow-up. Antipituitary antibodies immunostained selectively one type of pituitary-secreting cells in 21 patients (58.3 %, group 1), and several types of pituitary cells in the remaining 15 (41.7 %, group 2). All patients in group 1 showed subsequently a pituitary insufficiency, corresponding to the type of cells targeted by APA in 18 of them (85.7 %). Only 8 out of 15 patients in group 2 (53.3 %) showed a hypopituitarism, isolated in 7 and combined in the other one. None of APA negative patients showed hypopituitarism. The characterization of pituitary cells targeted by APA in patients with isolated autoimmune diseases, when the pituitary function is still normal, may help to foresee the kind of subsequent hypopituitarism, especially when APA immunostained selectively only one type of pituitary cells. A careful follow-up of pituitary function in these patients is advisable to allow an early diagnosis of hypopituitarism, even in subclinical phase and a consequent timely replacement therapy.

Aminopeptidase A (APA) is one of the many renal hydrolases. In mouse kidney, APA is predominantly expressed on the brush borders and sparsely on the basolateral membranes of proximal tubular epithelial cells. However, when large amounts of monoclonal antibodies (MAbs) against APA were injected into mice, we observed strong binding of the MAbs to the basolateral membranes, whereas the MAbs bound only transiently to the brush borders of the proximal tubular epithelial cells. In parallel, APA itself disappeared from the brush borders by both endocytosis and shedding, whereas it was increasingly expressed on the basolateral sides. Using ultrastructural immunohistology, we found no evidence for transcellular transport of endocytosed APA to the basolateral side of the proximal tubular epithelial cells. The absence of transcellular transport was confirmed by experiments in which we used a low dose of the MAbs. Such a low dose did not result in binding of the MAbs to the brush borders and had no effect on the presence of APA in the brush borders of the proximal tubular epithelial cells. In these experiments we still could observe binding of the MAbs to the basolateral membranes in parallel with the local appearance of APA. In addition, treatment of mice with chlorpromazine, a calmodulin antagonist that interferes with cytoskeletal function, largely inhibited the MAb-induced modulation of APA. Our studies suggest that injection of MAbs to APA specifically interrupts the normal intracellular traffic of this enzyme in proximal tubular epithelial cells. This intracellular transport is dependent on the action of cytoskeletal proteins.

Alternative polyadenylation of tumor suppressor genes in small intestinal neuroendocrine tumors.

The tumorigenesis of small intestinal neuroendocrine tumors (SI-NETs) is poorly understood. Recent studies have associated alternative polyadenylation (APA) with proliferation, cell transformation, and cancer. Polyadenylation is the process in which the pre-messenger RNA is cleaved at a polyA site and a polyA tail is added. Genes with two or more polyA sites can undergo APA. This produces two or more distinct mRNA isoforms with different 3' untranslated regions. Additionally, APA can also produce mRNAs containing different 3'-terminal coding regions. Therefore, APA alters both the repertoire and the expression level of proteins. Here, we used high-throughput sequencing data to map polyA sites and characterize polyadenylation genome-wide in three SI-NETs and a reference sample. In the tumors, 16 genes showed significant changes of APA pattern, which lead to either the 3' truncation of mRNA coding regions or 3' untranslated regions. Among these, 11 genes had been previously associated with cancer, with 4 genes being known tumor suppressors: DCC, PDZD2, MAGI1, and DACT2. We validated the APA in three out of three cases with quantitative real-time-PCR. Our findings suggest that changes of APA pattern in these 16 genes could be involved in the tumorigenesis of SI-NETs. Furthermore, they also point to APA as a new target for both diagnostic and treatment of SI-NETs. The identified genes with APA specific to the SI-NETs could be further tested as diagnostic markers and drug targets for disease prevention and treatment.

Microarray Meta-Analysis of RNA-Binding Protein Functions in Alternative Polyadenylation

Science.gov (United States)

Hu, Wenchao; Liu, Yuting; Yan, Jun

2014-01-01

Alternative polyadenylation (APA) is a post-transcriptional mechanism to generate diverse mRNA transcripts with different 3′UTRs from the same gene. In this study, we systematically searched for the APA events with differential expression in public mouse microarray data. Hundreds of genes with over-represented differential APA events and the corresponding experiments were identified. We further revealed that global APA differential expression occurred prevalently in tissues such as brain comparing to peripheral tissues, and biological processes such as development, differentiation and immune responses. Interestingly, we also observed widespread differential APA events in RNA-binding protein (RBP) genes such as Rbm3, Eif4e2 and Elavl1. Given the fact that RBPs are considered as the main regulators of differential APA expression, we constructed a co-expression network between APAs and RBPs using the microarray data. Further incorporation of CLIP-seq data of selected RBPs showed that Nova2 represses and Mbnl1 promotes the polyadenylation of closest poly(A) sites respectively. Altogether, our study is the first microarray meta-analysis in a mammal on the regulation of APA by RBPs that integrated massive mRNA expression data under a wide-range of biological conditions. Finally, we present our results as a comprehensive resource in an online website for the research community. PMID:24622240

Joint effect of freshwater plume and coastal upwelling on phytoplankton growth off the Changjiang River

The Changjiang (Yangtze) River discharges vast amount of unbalanced nutrients (dissolved inorganic nitrogen and phosphorus with N / P ratio > 80 in general) into the East China Sea in summer. To study nutrient dynamics and P-stress potential for phytoplankton, a cruise was conducted in the Changjiang plume during summer 2011. With 3-D observations of nutrients, chlorophyll a (Chl a), and bulk alkaline phosphatase activity (APA), we concluded that the Changjiang Diluted Water and coastal upwelling significantly influenced the horizontal and vertical heterogeneities of phytoplankton P deficiency in the Changjiang plume. Allochthonous APA was detected at nutrient-enriched freshwater end. Excessive N (~ 10 to 112 μM) was observed throughout the entire plume surface. In the plume fringe featuring stratification and excess N, diapycnal phosphate supply was blocked and phytoplankton APA was stimulated for growth. We observed an upwelling just attaching to the turbidity front at seaward side where Chl a peaked yet much less APA was detected. An external phosphate supply from subsurface, which promoted phytoplankton growth but inhibited APA, was suggested to be sourced from the Nearshore Kuroshio Branch Current. In the so hydrographically complicated Changjiang plume, phosphate supply instead of its concentration may be more important in determining the expression of APA. Meanwhile, allochthonous APA may also alter the usefulness of APA as a P-stress indicator.

The Alaska Power Administration (APA) will continue to encourage economic and industrial development in Alaska through implementing the sale of APA assets in a manner consistent with the authorizing legislation while balancing all the stakeholders` interests. Alaska Power Administration will provide their employees opportunities for successful career transitions and conduct an efficient transfer of assets and closeout of APA, while continuing to provide customers reliable, low-cost hydroelectric energy during the transition. The attached report presents the results of the independent certified public accounts` audit of the Alaska Power Administration`s (APA) combined power system statements of assets; Federal investment and liabilities; and the related combined statements of revenues, expenses and accumulated net revenues, and cash flows. The auditors` reports on APA`s internal control structure and compliance with laws and regulations disclosed no reportable conditions or instances of noncompliance. Based on the unqualified opinion of the independent public accounting firm of KPMG Peak Marwick LLP and review of their audit work, the authors believe the financial statements fairly present the financial condition and results of the operations of APA for the period under audit.

Should title lengths really adhere to the American Psychological Association's twelve word limit?

Science.gov (United States)

Hallock, Robert M; Dillner, Kari M

2016-04-01

The publication manual for the American Psychological Association (APA) suggests that title lengths do not exceed 12 words, yet journals do not prevent longer titles. Here, we examined title lengths in APA journals to see how many exceeded the APA's suggested limit. First, we conducted a systematic analysis of 235 articles in the current issues of 23 APA journals. A total of 52% of titles were more than 12 words long. Second, we examined articles from APA journals that were at least 50 years old to examine whether title lengths have changed over time. Our results suggested that the average title lengths have indeed increased with time. One of 2 courses should be taken. Perhaps science is becoming more complex that longer titles are needed in order to convey the primary message to the reader. If this is the case, then the APA's word limit should be increased. On the other hand, however, maybe editor and reviewers should try to enforce the current word limit to force writers to be succinct. Either way, editors should make their preferences clear so that the trend for longer titles does not continue unchecked. (c) 2016 APA, all rights reserved).

Lateral variations along the Himalayan arc are suggested by an increasing number of studies and carry important information about the orogen’s segmentation. Here we compile the hitherto most complete land gravity dataset in the region which enables the currently highest resolution plausible analysis. To study lateral variations in collisional structure we compute arc-parallel gravity anomalies (APaGA) by subtracting the average arc-perpendicular profile from our dataset; we compute likewise for topography (APaTA). We find no direct correlation between APaGA, APaTA and background seismicity, as suggested in oceanic subduction context. In the Himalayas APaTA mainly reflect relief and erosional effects, whereas APaGA reflect the deep structure of the orogen with clear lateral boundaries. Four segments are outlined and have disparate flexural geometry: NE India, Bhutan, Nepal & India until Dehradun, and NW India. The segment boundaries in the India plate are related to inherited structures, and the boundaries of the Shillong block are highlighted by seismic activity. We find that large earthquakes of the past millennium do not propagate across the segment boundaries defined by APaGA, therefore these seem to set limits for potential rupture of megathrust earthquakes.

1997-01-01

The carboxylation in aqueous solution of 6-amino-penicillanic acid (6-APA) to 8-hydroxy-penillic acid (8-HPA) was studied at 25 degrees C and pH 6.5. During sparging with either a citrate buffer or a chemically defined cultivation medium containing 6-APA with mixtures of carbon dioxide and air (2.......7-41% (v/v) CO2), the kinetics for conversion of 6-APA was followed by HPLC. In the citrate buffer 6-APA was converted by two competitive reactions each following first order kinetics with respect to the concentration of 6-APA: 1. carboxylation into 8-HPA; and 2. slow conversion into an unknown compound....... Formation of the unknown compound was not observed in the cultivation medium. The carboxylation of 6-APA was also found to be first order with respect to the concentration of dissolved carbon dioxide. The rate constant for formation of 8-HPA did not differ significantly in the cultivation medium compared...

With the increasing use of antiplatelet agents (APA), their management during the periendoscopic period has become a more common and more difficult problem. The increase in use is due to the availability of new drugs and the widespread use of drug-eluting coronary stents. Acute coronary syndromes can occur when APA therapy is withheld for noncardiovascular interventions. Guidelines about APA management during the periendoscopic period are traditionally based on assessments of the procedure-related risk of bleeding and the risk of thrombosis if APA are stopped. New data allow better assessment of these risks, of the necessary duration of APA discontinuation before endoscopy, of the use of alternative procedures (mostly for endoscopic retrograde cholangiopancreatography [ERCP]), and of endoscopic methods that can be used to prevent bleeding (following colonic polypectomy). This guideline makes graded, evidence-based, recommendations for the management of APA for all currently performed endoscopic procedures. A short summary and two tables are included for quick reference. © Georg Thieme Verlag KG Stuttgart · New York.

Femtosecond laser has been proposed as a method for conditioning zirconia surfaces to boost bond strength. However, metallic or ceramic bracket bonding to femtosecond laser-treated zirconia surfaces has not been tested. This study compared the effects of four conditioning techniques, including femtosecond laser irradiation, on shear bond strength (SBS) of metallic and ceramic brackets to zirconia.Three hundred zirconia plates were divided into five groups: 1) control (C); 2) sandblasting (APA); 3) silica coating and silane (SC); 4) femtosecond laser (FS); 5) sandblasting followed by femtosecond laser (APA+SC). A thermal imaging camera measured temperature changes in the zirconia during irradiation. Each group was divided into 2 subgroups (metallic vs ceramic brackets). SBS was evaluated using a universal testing machine. The adhesive remnant index (ARI) was registered and surfaces were observed under SEM. Surface treatment and bracket type significantly affected the bracket-zirconia bond strength. SBS was significantly higher (pbrackets in all groups (APA+FS > APA > FS > SC > control) than metallic brackets (APA+FS > FS > SC > APA > control). For metallic brackets, groups SC (5.99 ± 1.86 MPa), FS (6.72 ± 2.30 MPa) and APA+FS (7.22 ± 2.73 MPa) reported significantly higher bond strengths than other groups (p brackets, the highest bond strength values were obtained in groups APA (25.01 ± 4.45 MPa), FS (23.18 ± 6.51 MPa) and APA+FS (29.22 ± 8.20 MPa).Femtosecond laser enhances bond strength of ceramic and metallic brackets to zirconia. Ceramic brackets provide significantly stronger adhesion than metallic brackets regardless of the surface treatment method.

Anticipatory postural adjustment patterns during gait initiation across the adult lifespan.

Science.gov (United States)

Lu, Chiahao; Amundsen Huffmaster, Sommer L; Harvey, Jack C; MacKinnon, Colum D

2017-09-01

Gait initiation involves a complex sequence of anticipatory postural adjustments (APAs) during the transition from steady state standing to forward locomotion. APAs have four core components that function to accelerate the center of mass forwards and towards the initial single-support stance limb. These components include loading of the initial step leg, unloading of the initial stance leg, and excursion of the center of pressure in the posterior and lateral (towards the stepping leg) directions. This study examined the incidence, magnitude, and timing of these components and how they change across the lifespan (ages 20-79). 157 individuals performed five trials of self-paced, non-cued gait initiation on an instrumented walkway. At least one component of the APA was absent in 24% of all trials. The component most commonly absent was loading of the initial step leg (absent in 10% of all trials in isolation, absent in 10% of trials in conjunction with another missing component). Trials missing all four components were rare (1%) and were observed in both younger and older adults. There was no significant difference across decades in the incidence of trials without an APA, the number or type of APA components absent, or the magnitude or timing of the APA components. These data demonstrate that one or more components of the APA sequence are commonly absent in the general population and the spatiotemporal profile of the APA does not markedly change with ageing.

Characterising antimicrobial protein-membrane complexes

International Nuclear Information System (INIS)

Xun, Gloria; Dingley, Andrew; Tremouilhac, Pierre

2009-01-01

Full text: Antimicrobial proteins (AMPs) are host defence molecules that protect organisms from microbial infection. A number of hypotheses for AMP activity have been proposed which involve protein membrane interactions. However, there is a paucity of information describing AMP-membrane complexes in detail. The aim of this project is to characterise the interactions of amoebapore-A (APA-1) with membrane models using primarily solution-state NMR spectroscopy. APA-1 is an AMP which is regulated by a pH-dependent dimerisation event. Based on the atomic resolution solution structure of monomeric APA-1, it is proposed that this dimerisation is a prerequisite for ring-like hexameric pore formation. Due to the cytotoxicity of APA-1, we have developed a cell-free system to produce this protein. To facilitate our studies, we have adapted the cell-free system to isotope label APA-1. 13 C /15 N -enriched APA-1 sample was achieved and we have begun characterising APA-1 dimerisation and membrane interactions using NMR spectroscopy and other biochemical/biophysical methods. Neutron reflectometry is a surface-sensitive technique and therefore represents an ideal technique to probe how APA-1 interacts with membranes at the molecular level under different physiological conditions. Using Platypus, the pH-induced APA-1-membrane interactions should be detectable as an increase of the amount of protein adsorbed at the membrane surface and changes in the membrane properties. Specifically, detailed information of the structure and dimensions of the protein-membrane complex, the position and amount of the protein in the membrane, and the perturbation of the membrane phospholipids on protein incorporation can be extracted from the neutron reflectometry measurement. Such information will enable critical assessment of current proposed mechanisms of AMP activity in bacterial membranes and complement our NMR studies

Smooth Approximation l 0-Norm Constrained Affine Projection Algorithm and Its Applications in Sparse Channel Estimation

Science.gov (United States)

2014-01-01

We propose a smooth approximation l 0-norm constrained affine projection algorithm (SL0-APA) to improve the convergence speed and the steady-state error of affine projection algorithm (APA) for sparse channel estimation. The proposed algorithm ensures improved performance in terms of the convergence speed and the steady-state error via the combination of a smooth approximation l 0-norm (SL0) penalty on the coefficients into the standard APA cost function, which gives rise to a zero attractor that promotes the sparsity of the channel taps in the channel estimation and hence accelerates the convergence speed and reduces the steady-state error when the channel is sparse. The simulation results demonstrate that our proposed SL0-APA is superior to the standard APA and its sparsity-aware algorithms in terms of both the convergence speed and the steady-state behavior in a designated sparse channel. Furthermore, SL0-APA is shown to have smaller steady-state error than the previously proposed sparsity-aware algorithms when the number of nonzero taps in the sparse channel increases. PMID:24790588

Full Text Available Alternative polyadenylation (APA, a phenomenon that RNA molecules with different 3′ ends originate from distinct polyadenylation sites of a single gene, is emerging as a mechanism widely used to regulate gene expression. In the present review, we first summarized various methods prevalently adopted in APA study, mainly focused on the next-generation sequencing (NGS-based techniques specially designed for APA identification, the related bioinformatics methods, and the strategies for APA study in single cells. Then we summarized the main findings and advances so far based on these methods, including the preferences of alternative polyA (pA site, the biological processes involved, and the corresponding consequences. We especially categorized the APA changes discovered so far and discussed their potential functions under given conditions, along with the possible underlying molecular mechanisms. With more in-depth studies on extensive samples, more signatures and functions of APA will be revealed, and its diverse roles will gradually heave in sight.

Knee Trembling During Freezing of Gait Represents Multiple Anticipatory Postural Adjustments

Science.gov (United States)

Jacobs, Jesse V.; Nutt, John G.; Carlson-Kuhta, Patricia; Stephens, Marilee; Horak, Fay B.

2011-01-01

Freezing of gait (FoG) is an episodic, brief inability to step that delays gait initiation or interrupts ongoing gait. FoG is often associated with an alternating shaking of the knees, clinically referred to as knee trembling or trembling in place. The pathophysiology of FoG and of the concomitant trembling knees is unknown; impaired postural adjustment in preparation for stepping is one hypothesis. We examined anticipatory postural adjustments (APAs) prior to protective steps induced by a forward loss of balance in 10 Parkinson’s disease (PD) subjects with marked FoG and in 10 control subjects. The amplitude and timing of the APAs were determined from changes in the vertical ground-reaction forces recorded by a force plate under each foot and were confirmed by electromyographic recordings of bilateral medial gastrocnemius, tibialis anterior and tensor fascia latae muscles. Protective steps were accomplished with a single APA followed by a step for control subjects, whereas PD subjects frequently exhibited multiple, alternating APAs coexistent with the knee trembling commonly observed during FoG as well as delayed, inadequate or no stepping. These multiple APAs were not delayed in onset and were of similar or larger amplitude than the single APAs exhibited by the control subjects. These observations suggest that multiple APAs produce the knee trembling commonly associated with FoG and that FoG associated with a forward loss of balance is caused by an inability to couple a normal APA to the stepping motor pattern.

Protocol to assess the neurophysiology associated with multi-segmental postural coordination

Lomond, Karen V; Henry, Sharon M; Jacobs, Jesse V; Hitt, Juvena R; Horak, Fay B; Cohen, Rajal G; Schwartz, Daniel; Dumas, Julie A; Naylor, Magdalena R; Watts, Richard; DeSarno, Michael J

Anticipatory postural adjustments (APAs) stabilize potential disturbances to posture caused by movement. Impaired APAs are common with disease and injury. Brain functions associated with generating APAs remain uncertain due to a lack of paired tasks that require similar limb motion from similar postural orientations, but differ in eliciting an APA while also being compatible with brain imaging techniques (e.g., functional magnetic resonance imaging; fMRI). This study developed fMRI-compatible tasks differentiated by the presence or absence of APAs during leg movement. Eighteen healthy subjects performed two leg movement tasks, supported leg raise (SLR) and unsupported leg raise (ULR), to elicit isolated limb motion (no APA) versus multi-segmental coordination patterns (including APA), respectively. Ground reaction forces under the feet and electromyographic activation amplitudes were assessed to determine the coordination strategy elicited for each task. Results demonstrated that the ULR task elicited a multi-segmental coordination that was either minimized or absent in the SLR task, indicating that it would serve as an adequate control task for fMRI protocols. A pilot study with a single subject performing each task in an MRI scanner demonstrated minimal head movement in both tasks and brain activation patterns consistent with an isolated limb movement for the SLR task versus multi-segmental postural coordination for the ULR task.

As metoclopramide stimulates aldosterone secretion, we tested its usefulness in the assessment of lateralization of primary aldosteronism by adrenal vein sampling (AVS). Prospective within-patient study in consecutive patients undergoing AVS for primary aldosteronism subtyping. We compared the diagnostic accuracy of baseline and postmetoclopramide lateralization index and relative (to cortisol) aldosterone secretion indices (RASI) for each adrenal gland with aldosterone-producing adenoma (APA) determined by the four corners criteria as the reference diagnosis. We recruited 93 consecutive patients (mean age: 52 years; women 31%). Metoclopramide increased plasma aldosterone in the inferior vena cava and in both adrenal veins. The postmetoclopramide lateralization index was accurate in identifying APA, but did not increase diagnostic accuracy over baseline lateralization index, because the RASI increased similarly in both sides. Conversely, metoclopramide raised RASI to values more than 0.90 bilaterally in non-APA patients allowing accurate identification of factitious aldosterone suppression. In contrast, RASI was 0.90 or less in 48% contralateral to the tumor in APA patients. Regression analysis showed the APA patients with persistent suppression of RASI contralaterally showed a more florid primary aldosteronism phenotype. Metoclopramide does not enhance lateralization of aldosterone excess in APA, but consistently increased the value of RASI in non-APA cases, thus unmasking potentially misleading suppression of aldosterone. Postmetoclopramide RASI may therefore allow a more precise diagnosis when AVS can be achieved only unilaterally.

Adolescent-to-Parent Abuse as a Form of "Domestic Violence": A Conceptual Review.

Science.gov (United States)

Holt, Amanda

2016-12-01

Across the Global North, adolescent-to-parent abuse (APA) is becoming recognized as a significant social problem and is receiving attention from researchers, policymakers, and practitioners who work in the intersecting fields of juvenile justice, child protection, and domestic violence. One of the key questions shaping current debates concerns the extent to which APA maps onto the contours of domestic violence, in terms of research and theory, policy, and practice. In particular, to what extent can our established ways of working with domestic violence be applied when working with APA? This article begins by reviewing definitions and prevalence rates of APA. It then considers how the problem fits into the "family conflicts" and "gender-based violence" paradigms that are most frequently used to conceptualize domestic violence. The article then examines how APA represents a similar but distinct phenomenon to adult-instigated domestic violence and identifies how its departures represent particular challenges in working toward its elimination. The article concludes by reviewing intervention programs that work with APA and exploring some of the ways in which they adopt and reject elements of good practice from the domestic violence practice field. © The Author(s) 2015.

Structural insights into central hypertension regulation by human aminopeptidase A.

Hypertension is regulated through both the central and systemic renin-angiotensin systems. In the central renin-angiotensin system, zinc-dependent aminopeptidase A (APA) up-regulates blood pressure by specifically cleaving the N-terminal aspartate, but not the adjacent arginine, from angiotensin II, a process facilitated by calcium. Here, we determined the crystal structures of human APA and its complexes with different ligands and identified a calcium-binding site in the S1 pocket of APA. Without calcium, the S1 pocket can bind both acidic and basic residues through formation of salt bridges with the charged side chains. In the presence of calcium, the binding of acidic residues is enhanced as they ligate the cation, whereas the binding of basic residues is no longer favorable due to charge repulsion. Of the peptidomimetic inhibitors of APA, amastatin has higher potency than bestatin by fitting better in the S1 pocket and interacting additionally with the S3' subsite. These results explain the calcium-modulated substrate specificity of APA in central hypertension regulation and can guide the design and development of brain-targeting antihypertensive APA inhibitors.

2014-01-01

The tumorigenesis of small intestinal neuroendocrine tumors (SI-NETs) is poorly understood. Recent studies have associated alternative polyadenylation (APA) with proliferation, cell transformation, and cancer. Polyadenylation is the process in which the pre-messenger RNA is cleaved at a polyA site...... and a polyA tail is added. Genes with two or more polyA sites can undergo APA. This produces two or more distinct mRNA isoforms with different 3' untranslated regions. Additionally, APA can also produce mRNAs containing different 3'-terminal coding regions. Therefore, APA alters both the repertoire...... and the expression level of proteins. Here, we used high-throughput sequencing data to map polyA sites and characterize polyadenylation genome-wide in three SI-NETs and a reference sample. In the tumors, 16 genes showed significant changes of APA pattern, which lead to either the 3' truncation of mRNA coding regions...

Chemotherapy is the main treatment for patients with breast cancer metastases, but natural alternatives have been receiving attention for their potential as novel anti-tumor reagents. Amplexicaule A (APA) is a flavonoid glucoside isolated from rhizomes of Polygonum amplexicaule D. Don var. sinense Forb (PADF). We found that APA has anti-tumor effects in a breast cancer xenograft mouse model and induces apoptosis in breast cancer cell lines. APA increased levels of cleaved caspase-3,-8,-9 and PARP, which resulted from suppression of MCL-1 and BCL-2 expression in the cells. APA also inactivated the Akt/mTOR pathway in breast cancer cells. Thus, APA exerts a strong anti-tumor effect on breast cancer cells, most likely through induction of apoptosis. Our study is the first to identify this novel anti-tumor compound and provides a new strategy for isolation and separation of single compounds from herbs. PMID:26943775

The road less traveled: transarterial embolization of dural arteriovenous fistulas via the ascending pharyngeal artery.

Gross, Bradley A; Albuquerque, Felipe C; Moon, Karam; McDougall, Cameron G

2017-01-01

With the introduction of Onyx, transarterial embolization has become the most common endovascular approach to treating dural arteriovenous fistulas (dAVFs), often via the middle meningeal or occipital arteries. The ascending pharyngeal artery (APA) is a less frequently explored transarterial route because of its small caliber, potential anastomoses to the internal carotid and vertebral arteries, and vital supply to lower cranial nerves. To review our institutional experience and highlight the prevalence of APA supply to dAVFs and cases where it is a safe and effective pedicle for embolization. We reviewed our endovascular database (January 1, 1996 to March 1, 2016) for cranial dAVFs, evaluating dAVF characteristics and embolization results for those treated transarterially via the APA. Of 267 endovascularly treated dAVFs, 68 had APA supply (25%). Of these 68 dAVFs, embolization was carried out via this pedicle in 8 (12%) and 7 were ultimately occluded. No complications, including post-treatment cranial neuropathies or radiographic evidence of non-target embolization, were found. For 5 dAVFs, the APA was selected as the initial pedicle for embolization (two marginal sinus, one distal sigmoid, one cavernous, one tentorial). In four of these five cases, dAVF occlusion was achieved via the initial APA feeding artery pedicle. In one case, near-complete, stagnant occlusion was achieved after APA embolization; complete occlusion was achieved after adjunctive embolization of a single additional middle meningeal artery pedicle. In three other cases of complex transverse/sigmoid dAVFs, the APA was used after multiple attempts via middle meningeal and occipital artery pedicles. Occlusion was not achieved transarterially; two of these three dAVFs were ultimately occluded transvenously. In rare, select cases, the APA is an excellent route for transarterial embolization of cranial dAVFs. Published by the BMJ Publishing Group Limited. For permission to use (where not already

Soil acid phosphomonoesterase activity (APA) plays a vital role in controlling phosphorus (P) cycling and reflecting the current degree of P limitation Responses of soil APA to elevating nitrogen (N) deposition are important because of their potential applications in addressing the relationship between N and P in forest ecosystems.A study of responses of soll APA to simulated N deposition was conducted in three succession forests of subtropical China.The three forests include a Masson pine (Pinus massoniana) forest (MPF)—pioneer community,a coniferous and broad-leaved mixed forest (MF)—transition community and a monsoon evergreen broadleaved forest (MEBF)—climax community.Four N treatments were designed for MEBF:control (without N added),low-N (50 kg N ha-1 year-1),and medium-N (100 kg N ha-1 year-1) and high-N (150 kg N ha-1 year-1),and only three N treatments (i.e.,control,low-N,mediun-N) were established for MPF and MF.Results showed that soil APA was highest in MEBF.followed by MPF and MF.Soil APAs in both MPF and MF were not influenced by low-N treatments but depressed in medium-N trcatments.However,soil APA in MEBF exhibited negative responses to high N additions,indicating that the environment of enhanced N depositions would reduce P supply for the mature forest ecosystem.Soil APA and its responses to N additions in subtropical forests were closely related to the succession stages in the forests.

The stress-induced heat shock protein 70.3 expression is regulated by a dual-component mechanism involving alternative polyadenylation and HuR.

Heat shock protein 70.3 (Hsp70.3) expression increases in response to cellular stress and plays a cytoprotective role. We have previously shown that Hsp70.3 expression is controlled through coordinated post-transcriptional regulation by miRNAs and alternative polyadenylation (APA), and APA-mediated shortening of the Hsp70.3 3'-UTR facilitates increased protein expression. A stress-induced increase in Hsp70.3 mRNA and protein expression is accompanied by alternative polyadenylation (APA)-mediated truncation of the 3'UTR of the Hsp70.3 mRNA transcript. However, the role that APA plays in stress-induced expression of Hsp70.3 remains unclear. Our results show that APA-mediated truncation of the Hsp70.3 3'UTR increases protein expression through enhanced polyribosome loading. Additionally, we demonstrate that the RNA binding protein HuR, which has been previously shown to play a role in mediating APA, is necessary for heat shock mediated increase in Hsp70.3 mRNA and protein. However, it is somewhat surprising to note that HuR does not play a role in APA of the Hsp70.3 mRNA, and these two regulatory events appear to be mutually exclusive regulators of Hsp70.3 expression. These results not only provide important insight to the regulation of stress response genes following heat shock, but also contribute an enhanced understanding of how alternative polyadenylation contributes to gene regulation.

Alternative polyadenylation (APA) regulates mRNA translation, stability, and protein localization. However, it is unclear to what extent APA regulates these processes uniquely in specific cell types. Using a new technique, cTag-PAPERCLIP, we discovered significant differences in APA between the principal types of mouse cerebellar neurons, the Purkinje and granule cells, as well as between proliferating and differentiated granule cells. Transcripts that differed in APA in these comparisons were enriched in key neuronal functions and many differed in coding sequence in addition to 3’UTR length. We characterize Memo1, a transcript that shifted from expressing a short 3’UTR isoform to a longer one during granule cell differentiation. We show that Memo1 regulates granule cell precursor proliferation and that its long 3’UTR isoform is targeted by miR-124, contributing to its downregulation during development. Our findings provide insight into roles for APA in specific cell types and establish a platform for further functional studies. PMID:29578408

Of 211 admissions, we excluded 98 patients who were admitted at >30 days of age or did not survive/stay for >6 weeks. Bone radiographs obtained in 32 infants were reviewed by a radiologist masked to laboratory values. Results In this cohort of 113 infants, P-APA was found to have a significant inverse relationship with BW, gestational age and serum phosphorus. In paired comparisons, P-APA of infants Conclusion Elevation of P-APA >600 IU/L was very common in ELBW infants. BW was significantly inversely related to both P-APA and radiologic rickets. No single value of P-APA was related to radiological findings of rickets. Given the very high risk of osteopenia and rickets among ELBW infants, we recommend consideration of early screening and early mineral supplementation, especially among infants

In 1939, a psychologist could become a member of the Southern Society for Philosophy and Psychology (SSPP) automatically with the endorsement of two members, payment of dues, and membership in the American Psychological Association (APA). Non-APA members with endorsements and payment of dues had to be voted in by the membership. In 1940, the rules for admission were changed to eliminate the automatic membership for APA members. Francis Cecil Sumner, the first African American PhD in psychology, qualified for SSPP membership as a member of the APA in 1939, but the SSPP's council delayed his membership and introduced the amendment to its constitution that eliminated Sumner's route to membership. This article examines the circumstances surrounding council's actions and the role that Sumner's application for membership played in it as an example of the role that race and discrimination played in the decision to change the route to SSPP membership for members of the APA.

In order to determine the eyeball shape, the authors have carried out ultrasonic biometry of its three major parameters, the anteroposterior axis (APA), horizontal diameter (HD), and vertical diameter (VD), and estimated the ratios of these values (APA/HD and APA/VD) in children with emmetropia (234 eyes) and those with slight and medium-grave myopia (660 eyes), aged 7 to 14. The findings evidence a compressed ellipsoidal shape of the eyeball, presenting as a vertical oval, in all subjects with emmetropic refraction, whatever their age. In myopia the eyeball shape transforms, and all the eyeball sizes are increased, but the APA size is growing more rapidly than the rest sizes, and the eyeball acquires the ball shape with a trend to an elongated ellipsoidal shape. The mean APA length in 7-14-year-old children with emmetropia was up to 23 +/- 0.15 mm, whereas in those with the ball shape of the eyeball it was distended.

Purpose. Previous studies have studied the role of proprioception on the setting of anticipatory postural adjustments (APA) during gait initiation. However, these studies did not investigate the role of proprioception in the sagittal APA setting. We aimed to investigate the role of proprioception manipulation to induce APA sagittal adaptations on gait initiation. Methods. Fourteen healthy adults performed gait initiation without, and with, vibration applied before movement onset, and during m...

Alkaline phosphatase activity in the subtropical ocean: insights from nutrient, dust and trace metal addition experiments

Full Text Available Phosphorus is an essential nutrient for all life on earth. In the ocean, the most bioavailable form of phosphorus is inorganic phosphate, but in the extensive subtropical gyres, phosphate concentrations can be chronically low and limit primary productivity and nitrogen fixation. In these regions, organisms produce hydrolytic enzymes, such as alkaline phosphatase (AP, that enable them to utilize the more replete dissolved organic phosphorus (DOP pool to meet their cellular phosphorus demands. In this study, we synthesized data from 14 published studies and present our own findings from two research cruises (D326 and D361 in the eastern subtropical Atlantic to explore the relationship between AP activity (APA and nutrients, Saharan dust and trace metals. We found that below a threshold phosphate concentration of ~ 30 nM, APA increased with an inverse hyperbolic relationship with phosphate concentration. Meanwhile, DOP concentrations decreased with enhanced APA, indicating utilization of the DOP pool. We found APA rates were significantly higher in the subtropical Atlantic compared to the subtropical Pacific Ocean, even over the same low phosphate concentration range (0 to 50 nM. While the phosphate concentration may have a first order control on the APA rates, we speculate that other factors influence this basin scale contrast. Using bioassay experiments, we show that the addition of Saharan dust and zinc significantly increased the rate of APA. To our knowledge, our results are the first direct field-based evidence that APA is limited by zinc in the subtropical ocean. Further work is required to explore the relationship between trace metals such as iron and zinc, which are co-factors of phosphohydrolytic enzymes, specifically PhoX and PhoA, respectively, and APA in the ocean.

Full Text Available BACKGROUND: In Vietnam, as doctor of medicine is socially considered a special career, both men and women who are enrolled in medical universities often study topics of medicine seriously. However, as culturally expected, women often perform better than men. Because of this, teaching leadership and management skill (LMS to develop academic planning activity (APA for female medical students would also be expected to be more effective than male counterparts. This research aimed to compare by gender the effect of teaching LMS on increasing APA, using propensity score matching (PSM. METHODS: In a cross-sectional survey utilizing a self-reported structured questionnaire on a systematic random sample of 421 male and female medical students in Hanoi Medical University, this study adopted first regression techniques to construct a fit model, then PSM to create a matched control group in order to allow for evaluating the effect of LMS education. RESULTS: There were several interesting gender differences. First, while for females LMS education had both direct and indirect effects on APA, it had only direct effect on males' APA. Second, after PSM to adjust for the possible confounders to balance statistically two groups - with and without LMS education, there is statistically a significant difference in APA between male and female students, making a net difference of 11% (p<.01, equivalent to 173 students. The difference in APA between exposed and matched control group in males and females was 9% and 20%, respectively. These estimates of 9.0 and 20.0 percentage point increase can be translated into the practice of APA by 142 males and 315 females, respectively, in the population. These numbers of APA among male and female students can be explained by LMS education. CONCLUSIONS: Gender appears to be a factor explaining in part academic planning activity.

Aldosterone-producing adenoma (APA) is the main curable cause of endocrine hypertension cause of primary aldosteronism (PA) and it is in up to 66% of all cases investigated with adrenal vein sampling (AVS). Mutations in the KCNJ5 potassium channel involve up to 70% of APA and cause the most florid PA phenotypes. The recent finding that macrolide antibiotics specifically inhibit in vitro the altered function of mutated KCNJ5 channels has opened new horizons for the diagnosis and treatment of APA with KCNJ5 mutations in that it can allow identification and target treatment of PA patients harbouring a mutated APA. Thus, we aimed at investigating if clarithromycin and roxithromycin, two macrolides that potently blunt mutated Kir3.4 channel function in vitro, affect plasma aldosterone concentration in adrenal vein blood during AVS and in peripheral blood, respectively, in PA patients with a mutated APA. We designed two proof of concept studies. In study A: consecutive patients with an unambiguous biochemical evidence of PA will be exposed to a single dose of 250 mg clarithromycin during AVS, to assess its effect on the relative aldosterone secretion index in adrenal vein blood from the gland with and without APA. In study B: consecutive hypertensive patients submitted to the work-up for hypertension will receive a single oral dose of 150 mg roxithromycin. The experimental endpoints will be the change induced by roxithromycin of plasma aldosterone concentration and other steroids, direct active renin concentration, serum K + , systolic and diastolic blood pressure. We expect to prove that: (i) clarithromycin allows identification of mutated APA before adrenalectomy and sequencing of tumour DNA; (ii) the acute changes of plasma aldosterone concentration, direct active renin concentration, and blood pressure in peripheral venous blood after roxithromycin can be a proxy for the presence of an APA with somatic mutations.

Alternative polyadenylation (APA) is a mechanism that generates multiple mRNA isoforms with different 3'UTRs and/or coding sequences from a single gene. Here, using 3' region extraction and deep sequencing (3'READS), we have systematically mapped cleavage and polyadenylation sites (PASs) in Drosophila melanogaster , expanding the total repertoire of PASs previously identified for the species, especially those located in A-rich genomic sequences. Cis -element analysis revealed distinct sequence motifs around fly PASs when compared to mammalian ones, including the greater enrichment of upstream UAUA elements and the less prominent presence of downstream UGUG elements. We found that over 75% of mRNA genes in Drosophila melanogaster undergo APA. The head tissue tends to use distal PASs when compared to the body, leading to preferential expression of APA isoforms with long 3'UTRs as well as with distal terminal exons. The distance between the APA sites and intron location of PAS are important parameters for APA difference between body and head, suggesting distinct PAS selection contexts. APA analysis of the RpII215 C4 mutant strain, which harbors a mutant RNA polymerase II (RNAPII) with a slower elongation rate, revealed that a 50% decrease in transcriptional elongation rate leads to a mild trend of more usage of proximal, weaker PASs, both in 3'UTRs and in introns, consistent with the "first come, first served" model of APA regulation. However, this trend was not observed in the head, suggesting a different regulatory context in neuronal cells. Together, our data expand the PAS collection for Drosophila melanogaster and reveal a tissue-specific effect of APA regulation by RNAPII elongation rate. © 2017 Liu et al.; Published by Cold Spring Harbor Laboratory Press for the RNA Society.

Full Text Available Abstract The Psychological Ethics and National Security (PENS task force was assembled by the American Psychological Association (APA to guide policy on the role of psychologists in interrogations at foreign detention centers for the purpose of U.S. national security. The task force met briefly in 2005, and its report was quickly accepted by the APA Board of Directors and deemed consistent with the APA Ethics Code by the APA Ethics Committee. This rapid acceptance was unusual for a number of reasons but primarily because of the APA's long-standing tradition of taking great care in developing ethical policies that protected anyone who might be impacted by the work of psychologists. Many psychological and non-governmental organizations (NGOs, as well as reputable journalists, believed the risk of harm associated with psychologist participation in interrogations at these detention centers was not adequately addressed by the report. The present critique analyzes the assumptions of the PENS report and its interpretations of the APA Ethics Code. We demonstrate that it presents only one (and not particularly representative side of a complex set of ethical issues. We conclude with a discussion of more appropriate psychological contributions to national security and world peace that better respect and preserve human rights.

Direct percutaneous transaortic approach for treatment of aortic pseudoaneurysms.

Pirelli, Luigi; Kliger, Chad; Fontana, Gregory P; Ruiz, Carlos E

2015-05-01

Aortic pseudoaneurysms (APAs) can develop months or years after aortic and cardiac surgery. If not treated appropriately, APAs can lead to fatal complications and ultimately death. We describe a case of a 61-year old patient with a diagnosed large pseudoaneurysm 5 years after his aortic valve surgery, who was treated with a novel transcatheter direct transaortic approach. The patient had dilated cardiomyopathy with an APA adjacent to the lower sternal plate. An Amplatzer septal occlusion device followed by coils was delivered transcutaneously through the APA to close its neck and fill the false aneurysm, respectively. Triple fusion multimodality imaging was used to guide the placement of the occlusion devices. The merging of computed tomography (CT) and echocardiography with real-time fluoroscopy was fundamental in procedural planning and guidance. Post-procedural transoesophageal echocardiogram (TOE) and CT angiography showed complete exclusion of the APA. A direct transaortic approach is a valid option for closure of an APA if the surgical risk is prohibitive, and the use of triple fusion technology is an essential tool in the hands of interventionalists and surgeons for preoperative planning and conduction of these procedures. © The Author 2015.

We aimed to clarify postural control deficits in older adults with mild cognitive impairment (MCI) at high risk of falling by addressing the inhibitory process. This study involved 376 community-dwelling older adults with MCI. Participants were instructed to execute forward stepping on the side indicated by the central arrow while ignoring the 2 flanking arrows on each side (→→→→→, congruent, or →→←→→, incongruent). Initial weight transfer direction errors [anticipatory postural adjustment (APA) errors], step execution times, and divided phases (reaction, APA, and swing phases) were measured from vertical force data. Participants were categorized as fallers (n = 37) and non-fallers (n = 339) based on fall experiences in the last 12 months. There were no differences in the step execution times, swing phases, step error rates, and APA error rates between groups, but fallers had a significantly longer APA phase relative to non-fallers in trials of the incongruent condition with APA errors (p = 0.005). Fallers also had a longer reaction phase in trials with the correct APA, regardless of the condition (p = 0.01). Analyses of choice stepping with visual interference can detect prolonged postural preparation as a specific falling-associated deficit in older adults with MCI. © 2015 S. Karger AG, Basel.

Full Text Available Background. The persistent presence of antiphospholipid antibodies (APA may lead to the development of primary or secondary antiphospholipid syndrome. Although the genetic basis of APA has been suggested, the identity of the underlying genes is largely unknown. In this study, we have performed a genome-wide association study (GWAS in an effort to identify susceptibility loci/genes for three main APA: anticardiolipin antibodies (ACL, lupus anticoagulant (LAC, and anti-β2 glycoprotein I antibodies (anti-β2GPI. Methods. DNA samples were genotyped using the Affymetrix 6.0 array containing 906,600 single-nucleotide polymorphisms (SNPs. Association of SNPs with the antibody status (positive/negative was tested using logistic regression under the additive model. Results. We have identified a number of suggestive novel loci with PAPA. We have replicated the previously reported associations of HLA genes and APOH with APA but these were not the top loci. Conclusions. We have identified a number of suggestive novel loci for APA that will stimulate follow-up studies in independent and larger samples to replicate our findings.

The state of the psychology health service provider workforce.

Michalski, Daniel S; Kohout, Jessica L

2011-12-01

Numerous efforts to describe the health service provider or clinical workforce in psychology have been conducted during the past 30 years. The American Psychological Association (APA) has studied trends in the doctoral education pathway and the resultant effects on the broader psychology workforce. During this period, the creation and growth of the PsyD degree and the formalization of the predoctoral internship placement system (the APPIC Match) have been well noted, but efforts to gain a complete understanding of professional practice are lacking. Specifically, piecemeal research on the provider workforce has led to the study of specific subpopulations using varying approaches and definitions of those providing direct clinical service. Consequently, estimates of the supply and need for health service providers are distinctly divergent and generate protracted debate in organized psychology. The APA membership directory and the APA Doctorate Employment Surveys have traditionally been relied on for workforce analyses. Yet, these data have become characterized by limited generalizability in recent years because of declining survey response rates and the fact that APA member data may not be as representative of the entire psychology health service provider population as they were previously. The 2008 APA Survey of Psychology Health Service Providers targeted these limitations by including nonmember psychologists in the sampling frame. Results revealed emerging themes in the demographics, work settings, and delivery of health services of the psychology health service provider workforce. Future areas of research for APA and organized psychology to undertake in addressing need and demand are suggested. (PsycINFO Database Record (c) 2011 APA, all rights reserved).

Alternative cleavage and polyadenylation (APA) results in mRNA isoforms containing different 3’ untranslated regions (3’UTRs) and/or coding sequences. How core cleavage/polyadenylation (C/P) factors regulate APA is not well understood. Using siRNA knockdown coupled with deep sequencing, we found that several C/P factors can play significant roles in 3’UTR-APA. Whereas Pcf11 and Fip1 enhance usage of proximal poly(A) sites (pAs), CFI-25/68, PABPN1 and PABPC1 promote usage of distal pAs. Strong cis element biases were found for pAs regulated by CFI-25/68 or Fip1, and the distance between pAs plays an important role in APA regulation. In addition, intronic pAs are substantially regulated by splicing factors, with U1 mostly inhibiting C/P events in introns near the 5’ end of gene and U2 suppressing those in introns with features for efficient splicing. Furthermore, PABPN1 inhibits expression of transcripts with pAs near the transcription start site (TSS), a property possibly related to its role in RNA degradation. Finally, we found that groups of APA events regulated by C/P factors are also modulated in cell differentiation and development with distinct trends. Together, our results support an APA code where an APA event in a given cellular context is regulated by a number of parameters, including relative location to the TSS, splicing context, distance between competing pAs, surrounding cis elements and concentrations of core C/P factors.

Adrenal venous sampling (AVS) is critical to determine the subtype of primary aldosteronism (PA). Central AVS (C-AVS)--that is, the collection of effluents from bilateral adrenal central veins (CV)--sometimes does not allow differentiation between bilateral aldosterone-producing adenomas (APA) and idiopathic hyperaldosteronism. To establish the best treatment course, we have developed segmental AVS (S-AVS); that is, we collect effluents from the tributaries of CV to determine the intra-adrenal sources of aldosterone overproduction. We then evaluated the clinical utility of this novel approach in the diagnosis and treatment of PA. We performed C-AVS and/or S-AVS in 297 PA patients and assessed the accuracy of diagnosis based on the results of C-AVS (n=138, 46.5%) and S-AVS (n=159, 53.5%) by comparison with those of clinicopathological evaluation of resected specimens. S-AVS demonstrated both elevated and attenuated secretion of aldosterone from APA and non-tumorous segments, respectively, in patients with bilateral APA and recurrent APA. These findings were completely confirmed by detailed histopathological examination after surgery. S-AVS, but not C-AVS, also served to identify APA located distal from the CV. Compared to C-AVS, S-AVS served to identify APA in some patients, and its use should expand the pool of patients eligible for adrenal sparing surgery through the identification of unaffected segments, despite the fact that S-AVS requires more expertise and time. Especially, this new technique could enormously benefit patients with bilateral or recurrent APA because of the preservation of non-tumorous glandular tissue. © 2015 European Society of Endocrinology.

In 2017, the American Psychological Association (APA) celebrates the 125th anniversary of its founding. This special issue commemorates this milestone by providing long- and short-term views on the history of APA and its role in psychology in America. The opening paper presents an overview of initiatives and challenges facing the field of psychology and APA in five periods, each roughly 25 years in length. The remaining eight articles review specific issues and areas of activity over varying lengths of time in more recent years. Issues of policy involvement, relations with the media, and involvement with the courts are described, as well as developments related to social justice, education, science, practice, and publications.

Significance testing is widely used and often criticized. The Task Force on Statistical Inference of the American Psychological Association (TFSI, APA; Wilkinson & TFSI, 1999) addressed the use of significance testing and made recommendations that were incorporated in the fifth edition of the APA Publication Manual (APA, 2001). They emphasized the interpretation of significance testing and the importance of reporting confidence intervals and effect sizes. We examined whether 286 Psychonomic Bulletin & Review articles submitted before and after the publication of the TFSI recommendations by APA complied with these recommendations. Interpretation errors when using significance testing were still made frequently, and the new prescriptions were not yet followed on a large scale. Changing the practice of reporting statistics seems doomed to be a slow process.

Utilizando-se dados de chuva e vazão, obtidos durante um ano hidrológico, estabeleceram-se os regimes pluviométricos e fluviométricos e determinaram-se alguns parâmetros hidrológicos, como o fluxo de base pela técnica smoothed mínima e o coeficiente de recessão (α pela técnica matching strip. A análise conjugada destes parâmetros, de índices morfométricos e de dados físico-químicos das águas indicam que as bacias em áreas de relevo mais suave tendem a apresentar menores coeficientes de recessão e maiores volumes de fluxo de base. Portanto, nestas áreas o potencial hídrico é maior, já que a vazão das drenagens se mantém por mais tempo na estação seca. O relevo mais suave, com solo mais espesso e maior tempo de trânsito das águas subterrâneas, também justificam as águas mais redutoras e com maiores condutividades elétricas. Os dados também sugerem que as bacias da área com maiores proporções de florestas tendem a apresentar menores fluxos de base por conta das maiores taxas de evapotranspiração. Os métodos aplicados se mostraram adequados para caracterizar o regime hídrico de pequenas bacias hidrográficas e podem ser importantes para a gestão de recursos hídricos.

Chemotherapy is the main treatment for patients with breast cancer metastases, but natural alternatives have been receiving attention for their potential as novel anti-tumor reagents. Amplexicaule A (APA) is a flavonoid glucoside isolated from rhizomes of Polygonum amplexicaule D. Don var. sinense Forb (PADF). We found that APA has anti-tumor effects in a breast cancer xenograft mouse model and induces apoptosis in breast cancer cell lines. APA increased levels of cleaved caspase-3,-8,-9 and ...

The Economics of Advance Pricing Agreements

OpenAIRE

2014-01-01

Advance pricing agreements (APAs) determine transfer prices for intra-firm transactions in advance. This paper interprets these contracts as a means to overcome a hold-up problem that occurs because governments cannot commit to non-excessive future tax rates. In addition, with private information, just as in practice, our APAs will be complex and require lengthy negotiations. Never- theless, implemented APAs lead to a Pareto improvement even when all agents are risk neutral. However, not all ...

RNA regulatory elements and polyadenylation in plants

Directory of Open Access Journals (Sweden)

Arthur G. Hunt

2012-01-01

Full Text Available Alternative poly(A site choice (also known as alternative polyadenylation, or APA has the potential to affect gene expression in qualitative and quantitative ways. Alternative polyadenylation may affect as many as 82% of all expressed genes in a plant. The consequences of APA include the generation of transcripts with differing 3’-UTRs (and thus differing potential regulatory potential and of transcripts with differing protein-coding potential. Genome-wide studies of possible APA suggest a linkage with pre-mRNA splicing, and indicate a coincidence of and perhaps cooperation between RNA regulatory elements that affect splicing efficiency and the recognition of novel intronic poly(A sites. These studies also raise the possibility of the existence of a novel class of polyadenylation-related cis elements that are distinct from the well-characterized plant polyadenylation signal. Many potential APA events, however, have not been associated with identifiable cis elements. The present state of the field reveals a broad scope of APA, and also numerous opportunities for research into mechanisms that govern both choice and regulation of poly(A sites in plants.

Quantitative selenium-75-cholesterol imaging and computed tomography of the adrenal glands in Conn's syndrome

International Nuclear Information System (INIS)

Miller, J.L.

1982-01-01

Six consecutive patients with biochemically proven primary aldosteronism (4 with unilateral aldosteronomas and 2 with bilateral hyperplasia) underwent imaging with 75 Se-selenomethyl-nor-cholesterol (Scintadren; Radiochemical Centre, Amersham, UK) and computed tomography (CT) of the adrenal glands to aid in lateralizing unilateral aldosterone-producing adenomas (APA) and to differentiate APA from idiopathic adrenal hyperplasia (IAH). Scintadren quantitative imaging alone was successful in lateralizing the lesion in all 4 cases of unilateral APA; mean uptake by the affected adrenal gland was 0,47% of the administered dose as against 0,23% in the normal gland (P smaller than 0,01). The mean uptake ratio for the adenomatous as against the normal gland was 2,03 (range 1,75-2,21), which was significantly greater than the uptake ratio of 0,82 in 4 normal individuals (P smaller than 0,01). CT lateralized all the APAs. In the 2 cases of IAH, Scintadren uptake was bilaterally increased in one case in which CT was normal, whereas in the other case Scintadren uptakes were normal while CT showed two abnormal glands. The overall diagnostic yield for Scintadren was 83%; the figure for CT was also 83%. When the results of Scintadren imaging and CT are pooled, the accuracy in lateralizing APAs and differentiating APA from IAH as a cause of Conn's syndrome is 100%

Influence of chronic ethanol intake on mouse synaptosomal aspartyl aminopeptidase and aminopeptidase A: relationship with oxidative stress indicators.

Mayas, María Dolores; Ramírez-Expósito, María Jesús; García, María Jesús; Carrera, María Pilar; Martínez-Martos, José Manuel

2012-08-01

Aminopeptidase A (APA) and aspartyl aminopeptidase (ASAP) not only act as neuromodulators in the regional brain renin-angiotensin system, but also release N-terminal acidic amino acids (glutamate and aspartate). The hyperexcitability of amino acid neurotransmitters is responsible for several neurodegenerative processes affecting the central nervous system. The purpose of the present work was to study the influence of chronic ethanol intake, a well known neurotoxic compound, on APA and ASAP activity under resting and K(+)-stimulated conditions at the synapse level. APA and ASAP activity were determined against glutamate- and aspartate-β-naphthylamide respectively in mouse frontal cortex synaptosomes and in their incubation supernatant in a Ca(2+)-containing or Ca(2+)-free artificial cerebrospinal fluid. The neurotoxic effects were analyzed by determining free radical generation, peroxidation of membrane lipids and the oxidation of synaptosomal proteins. In addition, the bioenergetic behavior of synaptosomes was analyzed under different experimental protocols. We obtained several modifications in oxidative stress parameters and a preferential inhibitor effect of chronic ethanol intake on APA and ASAP activities. Although previous in vitro studies failed to show signs of neurodegeneration, these in vivo modifications in oxidative stress parameters do not seem to be related to changes in APA and ASAP, invalidating the idea that an excess of free acidic amino acids released by APA and ASAP induces neurodegeneration.

The realization of the potential importance of phosphorus (P) as a limiting nutrient in marine ecosystem is increasing globally. Hence, the contribution of biotic variables in mobilizing this nutrient would be relevant especially in productive coastal waters. As alkaline phosphatase activity (APA) indicates the status of P for primary production in aquatic environments, we asked the following question: is the level of APA indicative of P sufficiency or deficiency in coastal waters, especially, where upwelling is a regular phenomenon? Therefore, we have examined the total APA, chlorophyll a along with phosphatase producing bacteria (PPB) and related environmental parameters from nearshore to offshore in coastal waters off Trivandrum and Kochi regions differently affected by upwelling during the onset of monsoon. Off Trivandrum, APA in the offshore waters of 5-m layer at 2.23 μM P h- 1 was > 4 times higher than nearshore. Thus, low APA could be indicative of P sufficiency in coastal waters and higher activity suggestive of deficiency in offshore waters off Trivandrum. In contrast, there was less difference in APA between near and offshore surface waters off Kochi. Our results show that the regions differently affected by upwelling respond differently according to ambient P concentration, distance from shore or depth of water. These observations could apparently be applicable to other coastal systems as well, where gradients in upwelling and phosphate runoff have been noticed. Further studies on other transects would throw more light on the extent and direction of the relationship between APA and ambient P concentration. Such studies would help in understanding the level of control of this nutrient on the productivity of coastal waters.

Alternative Polyadenylation of Tumor Suppressor Genes in Small Intestinal Neuroendocrine Tumors

OpenAIRE

2014-01-01

The tumorigenesis of small intestinal neuroendocrine tumors (SI-NETs) is poorly understood. Recent studies have associated alternative polyadenylation (APA) with proliferation, cell transformation, and cancer. Polyadenylation is the process in which the pre-messenger RNA is cleaved at a polyA site and a polyA tail is added. Genes with two or more polyA sites can undergo APA. This produces two or more distinct mRNA isoforms with different 3′ untranslated regions. Additionally, APA can also pro...

Structures and related properties of helical, disulfide-stabilized peptides

Energy Technology Data Exchange (ETDEWEB)

Pagel, Mark D. [Univ. of California, Berkeley, CA (United States). Dept. of Chemistry

1993-11-01

The three dimensional structure of several peptides were determined by NMR spectroscopy and distance geometry calculations. Each peptide formed a predictable, rigid structure, consisting of an α-helix, a "scaffold" region which packed along one face of the helix, and two disulfide bridges which covalently connect the helix and scaffold regions. The peptide Apa-M5 was designed to constrain the M5 peptide from MLCK in a helical geometry using the apamin disulfide scaffold. This scaffold constrains the N- terminal end of the helix with two disulfide bridges and a reverse turn. Like the M5 peptide, Apa-M5 was found to bind calmodulin in a Ca²⁺-dependent 1:1 stoichiometry. However, the dissociation constant of the (Apa-M5)-calmodulin complex, 107 nM, was 100-fold higher than the dissociation constant of the M5-calmodulin complex. This difference was due to a putative steric overlap between the Apa-M5 scaffold and calmodulin. The peptide Apa-Cro was designed to replace the large structural protein matrix of λ Cro with the apamin disulfide scaffold. However, Apa-Cro did not bind the consensus DNA operator half-site of λ Cro, probably due to a steric overlap between the Apa-Cro disulfide framework and the DNA. The amino acid sequence of the scaffold-disulfide bridge arrangement of the peptide Max was derived from the core sequence of scyllatoxin, which contains an α-helix constrained at the C-terminal end by two disulfide bridges and a two-stranded βsheet scaffold. Max was shown to fold with >84% yield to form a predictable, stable structure that is similar to scyllatoxin. The folding and stability properties of Max make this scaffold and disulfide bridge arrangement an ideal candidate for the development of hybrid sequence peptides. The dynamics of a fraying C-terminal end of the helix of the peptide Apa-AlaN was determined by analysis of ¹⁵N NMR relaxation properties.

Objective To characterize preparation for compensatory stepping in people with Parkinson’s disease (PD) compared with healthy control subjects, and to determine whether levodopa medication improves preparation or the execution phases of the step. Design Observational study. Setting Outpatient neuroscience laboratory. Participants Nineteen participants with idiopathic PD tested both in the on and off levodopa states and 17 healthy subjects. Intervention Moveable platform with posterior translations of 24cm at 56cm/s. Main Outcome Measures Compensatory steps forward, in response to a backward surface translation (24cm amplitude at 56cm/s), were categorized according to the presence of an anticipatory postural adjustment (APA) before stepping: no APA, single APA, or multiple APAs. The following step parameters were calculated: step latency, step length, center of mass (CoM) average velocity, and CoM displacement at the step initiation. Results Lateral APAs were evident in 57% and 42% of trials for people with PD in the off and on medication states, respectively, compared with only 10% of trials for control subjects. Compared with subjects with PD who did not have APAs, those subjects with PD who did make an APA prior to stepping had significantly later (mean ± SEM, 356 ± 16ms vs 305 ± 8ms) and shorter (mean ± SEM, 251 ± 27mm vs 300 ± 16mm) steps, their CoM was significantly farther forward (185 ± 7mm vs 171 ± 5mm) at foot-off, and they took significantly more steps to regain equilibrium. Levodopa did not affect the preparation or execution phase of compensatory stepping. Poor axial scores and reports of freezing in the United Parkinson’s Disease Rating Scale were associated with use of 1 or more APAs before compensatory stepping. Conclusions Lateral postural preparation prior to compensatory stepping in subjects with PD was associated with inefficient balance recovery from external perturbations. PMID:20801249

The problems of abused and neglected children are epidemic in our society (U.S. Department of Health and Human Services, Administration on Children, Youth, and Families, 2008) and create issues that psychologists may be called upon to address. Psychologists are positioned to contribute significantly to decision making in child protection matters. Psychological data and expertise may provide sources of information and a perspective not otherwise available to courts regarding the functioning of parties, and thus may increase the fairness of decisions by the court, state agency, or other party. such matters. These guidelines are a revision of the 1999 "Guidelines for Psychological Evaluations in Child Protection Matters" (American Psychological Association [APA], 1999). These guidelines are informed by APA's "Ethical Principles of Psychologists and Code of Conduct" ("APA Ethics Code"; APA, 2002a, 2010).

Are the American Psychological Association's Detainee Interrogation Policies Ethical and Effective?: Key Claims, Documents, and Results.

2011-01-01

After 9-11, the United States began interrogating detainees at settings such as Abu Ghraib, Bagram, and Guantanamo. The American Psychological Association (APA) supported psychologists' involvement in interrogations, adopted formal policies, and made an array of public assurances. This article's purpose is to highlight key APA decisions, policies, procedures, documents, and public statements in urgent need of rethinking and to suggest questions that may be useful in a serious assessment, such as, "However well intended, were APA's interrogation policies ethically sound?"; "Were they valid, realistic, and able to achieve their purpose?"; "Were other approaches available that would address interrogation issues more directly, comprehensively, and actively, that were more ethically and scientifically based, and that would have had a greater likelihood of success?"; and "Should APA continue to endorse its post-9-11 detainee interrogation policies?"

Critical Pedagogy and APA: A Resonant (and Timely) Interdisciplinary Blend.

Science.gov (United States)

Connolly, Maureen; Harvey, William J

2018-04-12

Critical pedagogy owes much of its emergence, development, and ongoing relevance to the work of Paulo Freire whose legacy remains relevant for a next generation of scholars who seek to explore issues of inclusion, oppression, social justice, and authentic expression. An interdisciplinary dialogue between critical pedagogy and adapted physical activity is timely, appropriate, and should focus on complex profiles of neurodiversity, mental illness, and mental health, with emphasis on pedagogic practices of practitioners in service delivery and teacher educators who prepare them for professional practice. A case-based scenario approach is used to present practitioner and teacher educator practices. Concrete examples are provided for analyzing and understanding deeper issues and challenges related to neurodiversity in a variety of embodied dimensions in educational and activity contexts. We work with Szostak's approach to interdisciplinary research and model an analysis strategy that integrates and applies the methodological features of interdisciplinarity, adapted physical activity, and critical pedagogy.

This study reviewed 402 empirical research papers published during 1999 in 9 American Psychological Association journals from the perspective of the Personal Dimensions of Identity (PDI) model. Descriptions of participants were reviewed to determine whether researchers reported information concerning Dimensions A, B, and C of the PDI model. PDI A and B Dimensions of age, gender, education, and geographic location were reported with the highest frequency: 88.56%, 89.30%, 78.50%, and 73.88%, respectively, whereas race/ethnicity was reported with moderate frequency, 60.70%. The remaining PDI A Dimensions of language, physical disability, sexual orientation, and social class, and the remaining B Dimensions of citizenship status, employment status, income, marital status, military experience, occupation, and religion, were reported in relatively low percentages of studies.

Uranium(VI) adsorption properties of a chelating resin containing polyamine-substituted methylphosphonic acid moiety

International Nuclear Information System (INIS)

Matsuda, Masaaki; Akiyoshi, Yoshirou

1991-01-01

Uranium(VI) adsorption and desorption properties of a chelating resin containing polyamine-substituted methylphosphonic acid moiety of 2.29 mmol/g-resin (APA) were examined. Uranium(VI) adsorption properties of several ion exchange resins and extractant agents which were known as excellent adsorbents for uranium(VI), were examined together for a comparison with those of APA. Uranium(VI) adsorption capacity of APA at the concentration of 100 mg·dm -3 -uranium(VI) in 100 g·dm -3 -H 2 SO 4 aq. soln., 190 g·dm -3 -H 3 PO 4 aq. soln. and uranium enriched sea water, was 0.2, 0.05 and 0.05 mmol·g -1 respectively. The adsorption capacity of APA for uranium(VI) in these solutions was larger than that of another adsorbents, except the adsorption of uranium(VI) in enriched sea water on ion exchange resin containing phosphoric acid moiety (adsorption capacity ; 0.2 mmol·g -1 ). Uranium(VI) adsorption rate on APA was high and the relation between treatment time (t : min) and uranium(VI) concentration (y : mg·dm -3 ) in 100 g·dm -3 H 2 SO 4 aq. soln. after treatment, was shown as following equation, y=20 0.048t+1.90 (0≤t≤30). The adsorbed uranium(VI) on APA was able to be eluted with a mixed aq. soln. of hydrogen peroxide and sodium hydroxide and also was able to be eluted with an aq. alkaline soln. dissolved reduction agents such as sodium sulfite and hydrazine. From these results, it was thought that uranium(VI) adsorbed on APA was eluted due to the reduction to uranium(VI) by these eluents. (author)

Managing Assets Of Agricultural Property Of The National Treasury In The Context Of State Aid Granted By The Agricultural Property Agency

Lizińska Wiesława

2015-09-01

Full Text Available This study covers the issue of activities of the Agricultural Property Agency in terms of state aid in the form of non-repayable financial aid, with the following specific objectives: determining the scale and diversity of state aid granted by the APA (including the local branch in Olsztyn, evaluating the current technical condition of some of the assets and their condition upon being handed over by the APA, determining their importance, main problems associated with resources which are taken over, identifying and assessing the importance of actions which encourage communes to take over property still held by the APA, assessing the scale and procedure of aid granted in the opinion of representatives of APA units. The article makes use of information obtained from the local branch of the APA in Olsztyn in the years 2003-2014. A direct survey among the entities was taken. The survey questionnaire was sent in 2014 to all communes (gminas of the Province (Voivodeship of Warmia and Mazury (116 units. Completed questionnaires were returned by 73 representatives of the communes. A total of PLN 327.1 million was allotted in the Agency’s financial plans for the program of non-repayable financial aid during the period from 2009 to 2014. Approximately 81.6% of PLN 164.4 million granted by the local branch of the APA in Olsztyn, was granted to units of the public finance sector. As was shown in the survey conducted among representatives of local governments, the interest of communes in taking over assets still held by2 the local branch of the APA in Olsztyn could be increased by limiting the number of tenants who do not pay the rent regularly and by increasing the amount of non-repayable financial aid. It is possible to carry out the latter action, but the former could prove to be extremely difficult.

Influence of fear of falling on anticipatory postural control of medio-lateral stability during rapid leg flexion.

Science.gov (United States)

Yiou, E; Deroche, T; Do, M C; Woodman, T

2011-04-01

During leg flexion from erect posture, postural stability is organized in advance during "anticipatory postural adjustments" (APA). During these APA, inertial forces are generated that propel the centre of gravity (CoG) laterally towards stance leg side. This study examined how fear of falling (FoF) may influence this anticipatory postural control of medio-lateral (ML) stability. Ten young healthy participants performed a series of leg flexions at maximal velocity from low and high surface heights (6 and 66 cm above ground, respectively). In this latter condition with increased FoF, stance foot was placed at the lateral edge of the support surface to induce maximal postural threat. Results showed that the amplitude of ML inertial forces generated during APA decreased with FoF; this decrease was compensated by an increase in APA duration so that the CoG position at time of swing foot-off was located further towards stance leg side. With these changes in ML APA, the CoG was propelled in the same final (unipodal) position above stance foot as in condition with low FoF. These results contrast with those obtained in the literature during quiet standing which showed that FoF did not have any influence on the ML component of postural control. It is proposed that ML APA are modified with increased FoF, in such a way that the risk of a sideway fall induced by the large CoG motion is attenuated.

Correlation of Traditional Point a With Anatomic Location of Uterine Artery and Ureter in Cancer of the Uterine Cervix

2007-01-01

Purpose: Point A, used for dose specification for intracavitary brachytherapy for cervical cancer, is the point at which the uterine artery and ureter cross. This study assessed compatibility of commonly used traditional point A (TPA) and actual anatomic point A (APA). Methods and Materials: We visualized and placed radiopaque clips at the APA during pelvic and paraaortic lymphadenectomy in 11 patients with cervical carcinoma. Orthogonal and oblique radiographs were obtained after insertion of brachytherapy applicators. We measured the distance between the TPA and APA and estimated the brachytherapy dose to each of the two points. Results: A total of 64 brachytherapy treatments were performed. The mean distances between the TPA and APA were 5.2 ± 1.0 cm on the right and 5.4 ± 1.1 cm on the left. The estimated brachytherapy doses delivered to the APA as a percentage of the presumed 500-cGy fraction size to the TPA were 35.2% (176.6 ± 59.0 cGy) on the right and 30.0% (150.2 ± 42.9 cGy) on the left. The marked discrepancy in the position of the two points was not related to individual kinetic variations during brachytherapy treatment, tumor size, or bladder filling. Conclusions: The conventional TPA does not provide an accurate estimate of the APA determined during lymphadenectomy, indicating a need to reevaluate the current practice for determining the brachytherapy prescription for cervical cancer.

Role of Nox2 and p22phox in Persistent Postoperative Hypertension in Aldosterone-Producing Adenoma Patients after Adrenalectomy

Directory of Open Access Journals (Sweden)

Xiaojing Geng

2016-01-01

Full Text Available Adrenal aldosterone-producing adenoma (APA, producing the salt-retaining hormone aldosterone, commonly causes secondary hypertension, which often persists after unilateral adrenalectomy. Although persistent hypertension was correlated with residual hormone aldosterone, the in vivo mechanism remains unclear. NADPH oxidase is the critical cause of aldosterone synthesis in vitro. Nox2 and p22phox comprise the NADPH oxidase catalytic core, serving to initiate a reactive oxygen species (ROS cascade that may participate in the pathology. mRNAs of seven NADPH oxidase isoforms in APA were evaluated by RT-PCR and Q-PCR and their proteins by immunohistochemistry and Western blotting. NADPH oxidase activity was also detected. Nox2 and p22phox were especially abundant in APA. Particularly higher Nox2 and p22phox gene and protein levels were seen in APA than controls. Significant correlations between Nox2 mRNA and aldosterone synthase (CYP11B2 mRNA (R=0.66, P<0.01 and Nox2 protein and baseline plasma aldosterone concentration (PAC (R=0.503, P<0.01 were detected in APA; however, none were found between p22phox mRNA, CYP11B2 mRNA, p22phox protein, and baseline PAC. Importantly, we found that Nox2 localized specifically in hyperplastic zona glomerulosa cells. In conclusion, our results highlight that Nox2 and p22phox may be directly involved in pathological aldosterone production and zona glomerulosa cell proliferation after APA resection.

Same-sex parenting and children's outcomes: A closer examination of the American psychological association's brief on lesbian and gay parenting.

Science.gov (United States)

Marks, Loren

2012-07-01

In 2005, the American Psychological Association (APA) issued an official brief on lesbian and gay parenting. This brief included the assertion: "Not a single study has found children of lesbian or gay parents to be disadvantaged in any significant respect relative to children of heterosexual parents" (p. 15). The present article closely examines this assertion and the 59 published studies cited by the APA to support it. Seven central questions address: (1) homogeneous sampling, (2) absence of comparison groups, (3) comparison group characteristics, (4) contradictory data, (5) the limited scope of children's outcomes studied, (6) paucity of long-term outcome data, and (7) lack of APA-urged statistical power. The conclusion is that strong assertions, including those made by the APA, were not empirically warranted. Recommendations for future research are offered. Copyright © 2012 Elsevier Inc.

The psychiatric evaluation of a physician's fitness for duty is an undertaking that is both important to patients' well-being and to the physician-subject of the evaluation. It is necessary that psychiatrists who agree to perform such evaluations proceed in a careful and thorough manner. This document was developed to provide general guidance to the psychiatric evaluators in these situations. It was prepared by the American Psychiatric Association (APA) Council on Psychiatry and Law and Corresponding Committee on Physician Health, Illness, and Impairment, of which the authors are members. The Resource Document was approved by the APA Joint Reference Committee in June 2004. APA Resource Documents do not represent official policy of the American Psychiatric Association. This Resource Document was edited to conform to Journal style and has therefore been modified slightly from the original document approved by the APA.

Advanced paternal age effects in neurodevelopmental disorders-review of potential underlying mechanisms.

Science.gov (United States)

Janecka, M; Mill, J; Basson, M A; Goriely, A; Spiers, H; Reichenberg, A; Schalkwyk, L; Fernandes, C

2017-01-31

Multiple epidemiological studies suggest a relationship between advanced paternal age (APA) at conception and adverse neurodevelopmental outcomes in offspring, particularly with regard to increased risk for autism and schizophrenia. Conclusive evidence about how age-related changes in paternal gametes, or age-independent behavioral traits affect neural development is still lacking. Recent evidence suggests that the origins of APA effects are likely to be multidimensional, involving both inherited predisposition and de novo events. Here we provide a review of the epidemiological and molecular findings to date. Focusing on the latter, we present the evidence for genetic and epigenetic mechanisms underpinning the association between late fatherhood and disorder in offspring. We also discuss the limitations of the APA literature. We propose that different hypotheses relating to the origins of the APA effects are not mutually exclusive. Instead, multiple mechanisms likely contribute, reflecting the etiological complexity of neurodevelopmental disorders.

Phenomenology and adapted physical activity: philosophy and professional practice.

Science.gov (United States)

Standal, Øyvind F

2014-01-01

Through the increased use of qualitative research methods, the term phenomenology has become a quite familiar notion for researchers in adapted physical activity (APA). In contrast to this increasing interest in phenomenology as methodology, relatively little work has focused on phenomenology as philosophy or as an approach to professional practice. Therefore, the purpose of this article is to examine the relevance of phenomenology as philosophy and as pedagogy to the field of APA. First, phenomenology as philosophy is introduced through three key notions, namely the first-person perspective, embodiment, and life-world. The relevance of these terms to APA is then outlined. Second, the concept of phenomenological pedagogy is introduced, and its application and potential for APA are discussed. In conclusion, it is argued that phenomenology can help theorize ways of understanding human difference in movement contexts and form a basis of action-oriented research aiming at developing professional practice.

2017-07-01

To examine the effects of cue timing, across 3 sensory modalities, on anticipatory postural adjustments (APAs) during gait initiation in people with Parkinson disease (PD). Observational study. Biomechanics research laboratory. Individuals with idiopathic PD (N=25; 11 with freezing of gait [FOG]) were studied in the off-medication state (12-h overnight withdrawal). Gait initiation was tested without cueing (self-initiated) and with 3 cue timing protocols: fixed delay (3s), random delay (4-12s), and countdown (3-2-1-go, 1-s intervals) across 3 sensory modalities (acoustic, visual, and vibrotactile). The incidence and spatiotemporal characteristics of APAs during gait initiation were analyzed, including vertical ground reaction forces and center of pressure. All cue timings and modalities increased the incidence and amplitude of APAs compared with self-initiated stepping. Acoustic and visual cues, but not vibrotactile stimulation, improved the timing of APAs. Fixed delay or countdown timing protocols were more effective at decreasing APA durations than random delay cues. Cue-evoked improvements in APA timing, but not amplitude, correlated with the level of impairment during self-initiated gait. Cues did not improve the late push-off phase in the FOG group. External cueing improves gait initiation in PD regardless of cue timing, modality, or clinical phenotype (with and without FOG). Acoustic or visual cueing with predictive timing provided the greatest improvements in gait initiation; therefore, these protocols may provide the best outcomes when applied by caregivers or devices.

Errors in Postural Preparation Lead to Increased Choice Reaction Times for Step Initiation in Older Adults

Science.gov (United States)

Nutt, John G.; Horak, Fay B.

2011-01-01

Background. This study asked whether older adults were more likely than younger adults to err in the initial direction of their anticipatory postural adjustment (APA) prior to a step (indicating a motor program error), whether initial motor program errors accounted for reaction time differences for step initiation, and whether initial motor program errors were linked to inhibitory failure. Methods. In a stepping task with choice reaction time and simple reaction time conditions, we measured forces under the feet to quantify APA onset and step latency and we used body kinematics to quantify forward movement of center of mass and length of first step. Results. Trials with APA errors were almost three times as common for older adults as for younger adults, and they were nine times more likely in choice reaction time trials than in simple reaction time trials. In trials with APA errors, step latency was delayed, correlation between APA onset and step latency was diminished, and forward motion of the center of mass prior to the step was increased. Participants with more APA errors tended to have worse Stroop interference scores, regardless of age. Conclusions. The results support the hypothesis that findings of slow choice reaction time step initiation in older adults are attributable to inclusion of trials with incorrect initial motor preparation and that these errors are caused by deficits in response inhibition. By extension, the results also suggest that mixing of trials with correct and incorrect initial motor preparation might explain apparent choice reaction time slowing with age in upper limb tasks.

Full Text Available While antineutrophil cytoplasmic antibody (ANCA positivity has been documented in some patients with postinfectious glomerulonephritis (PIGN and is associated with more severe disease, antiphospholipid antibodies (APA are not known to be a common occurrence. We describe a child with severe acute kidney injury who was noted to have prolonged positivity of both ANCA and APA; a renal biopsy showed noncrescentic immune complex mediated glomerulonephritis with subepithelial deposits compatible with PIGN. He recovered without maintenance immunosuppressive therapy and at last follow-up had normal renal function. We discuss the cooccurrence and implications of ANCA and APA in children with PIGN.

Regional heating patterns of RF hyperthermia applicators in phantoms

International Nuclear Information System (INIS)

Kantor, G.; Ruggera, P.S.; Samulski, T.V.

1984-01-01

An elliptical phantom (20 cm by 30 cm cross-section and 40 cm long) with a 1 cm fat layer filled with muscle material was used to compare the induced heating patterns of the NCDRH helical coil, a Henry Medical Magnetrode coil, both with a diameter of 35.6 cm, and the BSD Annular Phased Array System (APAS). Temperature profiles were taken in the midplane cross-sectional slice along the major and minor axes of the phantom. These profiles were measured with a Vitek thermistor probe and the associated specific absorption rates (SAR) were determined from this data. SAR curves for each applicator were obtained along the major and minor axes of the phantom. The depths of heating of the Magnetrode applicator are considerably smaller than those for the helical applicator. Heating patterns for the APAS can be highly variable and asymmetric depending on the frequency of operation and the location of the phantom within the APAS aperture. While the APAS requires a water bolus for good coupling, the NCDRH and Magnetrode coils need only to be air coupled for good phantom coupling. Both the helical applicator and APAS can provide significant heating in the central region of the phantom. However, the heating of the helical coil does not critically depend on the phantom loading

Partial purification and identification of the thrombozane A2/prostaglandin H2 receptor protein in human platelets

International Nuclear Information System (INIS)

Lim, C.T.; Kattelman, E.J.; Arora, S.K.; Venton, D.L.; Le Breton, G.C.

1986-01-01

The thromboxane A 2 /prostaglandin H 2 (TXA 2 /PGH 2 ) receptor antagonist [ 3 H]-13-azaprostanoic acid (13-APA) was used to identify and purify the platelet TXA 2 /PGH 2 receptor protein. Optimal solubilization of the 13-APA binding protein was achieved by extraction with 3-[(3-cholamidopropyl)dimethyl-ammonio]-1-propanesulfonate (CHAPS) detergent. Preliminary purification of the crude solubilized membrane fraction was performed by gel filtration chromatography using a Sepharose 4B column. Further purification was accomplished by high performance liquid chromatography (HPLC) using a Synchropak GPC-500 column. The HPLC protein profile revealed two protein peaks, only one of which was enriched in [ 3 H]-13-APA. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of this peak revealed two bands with molecular weights of 65,000 and 60,000 daltons. In binding studies using the 60,000 dalton-enriched subfraction, unlabelled 13-APA, the TXA 2 /PGH 2 mimetic U46619 and the TXA 2 /PGH 2 antagonist SQ 29,548 all competed for [ 3 H]-13-APA binding whereas TXB 2 did not compete for binding. Heat denaturation of this subfraction resulted in a complete loss of binding activity. These findings indicate that a protein of approximately 60,000 daltons represents the human platelet TXA 2 /PGH 2 receptor

The Role of Proprioception in the Sagittal Setting of Anticipatory Postural Adjustments During Gait Initiation

Directory of Open Access Journals (Sweden)

Pereira Marcelo P.

2015-12-01

Full Text Available Purpose. Previous studies have studied the role of proprioception on the setting of anticipatory postural adjustments (APA during gait initiation. However, these studies did not investigate the role of proprioception in the sagittal APA setting. We aimed to investigate the role of proprioception manipulation to induce APA sagittal adaptations on gait initiation. Methods. Fourteen healthy adults performed gait initiation without, and with, vibration applied before movement onset, and during movement. In addition, the effects of two different vibration frequencies (80 and 120Hz were tested. Vibration was applied bilaterally on the tibialis anterior, rectus femoris and trapezius superior. The first step characteristics, ground reaction forces and CoP behaviour were assessed. Results. Vibration improved gait initiation performance regardless of the moment it was applied. CoP velocity during the initial phase of APA was increased by vibration only when it was applied before movement. When vibration was applied to disturb the movement, no effects on the CoP behaviour were observed. Manipulation of vibration frequency had no effects. Conclusions. Rather than proprioception manipulation, the results suggest that post-vibratory effects and attentional mechanisms were responsible for our results. Taken together, the results show that sagittal APA setting is robust to proprioception manipulation.

Full Text Available Objectives. The objective of this one-group, repeated-measures design was to explore the acceptance of auricular point acupressure (APA to reduce chronic low back pain (CLBP and estimate minimum clinically important differences (MCIDs for pain intensity change. Methods. Subjects received 7-day APA treatment. After appropriate acupoints were identified, vaccaria seeds were carefully taped onto each selected auricular point for 7-day. The Brief Pain Inventory Short Form (BPI was used to collect outcome data. Results. A total of 74 subjects participated in the study. Ten subjects dropped out and the retention rate was 87%. Subjects reported a 46% reduction in BPI worst pain, and over 50% reduction in BPI average pain, overall pain severity and pain interference by the end of study, and 62.5% subjects also reported less pain medication use. The MCIDs for the subscale of BPI ranged from .70 to 1.86 points. The percentage improvement of MCIDs from baseline was between 14.5–24.9%. Discussion. APA appears to be highly acceptable to patients with CLBP. A sham group is needed in order to differentiate the true effects of APA from the possible psychological effects of more frequent visits by the auricular therapist and patients’ expectation of the APA treatment.

New Perspectives on Rodent Models of Advanced Paternal Age: Relevance to Autism

Directory of Open Access Journals (Sweden)

Claire J Foldi

2011-06-01

Full Text Available Offspring of older fathers have an increased risk of various adverse health outcomes, including autism and schizophrenia. With respect to biological mechanisms for this association, there are many more germline cell divisions in the life history of a sperm relative to that of an oocyte. This leads to more opportunities for copy error mutations in germ cells from older fathers. Evidence also suggests that epigenetic patterning in the sperm from older men is altered. Rodent models provide an experimental platform to examine the association between paternal age and brain development. Several rodent models of advanced paternal age (APA have been published with relevance to intermediate phenotypes related to autism. All four published APA models vary in key features creating a lack of consistency with respect to behavioural phenotypes. A consideration of common phenotypes that emerge from these APA-related mouse models may be informative in the exploration of the molecular and neurobiological correlates of APA.

Faculty application of the American Psychological Association style.

Morse, Gwen Goetz

2009-10-01

This article explores current faculty methods with the application and evaluation of the American Psychological Association (APA) style. Specific aims were to determine concerns related to APA style, review faculty grading practices, identify institutional resources, and report potential solutions for improving application of APA style. A survey with an exploratory descriptive research design was developed and distributed online to academic chairs and deans, requesting their support in distributing the survey to their faculty. Responses (N = 704) were grouped into five categories: departmental and personal concerns; faculty grading practices; institutional resources; format, writing style, and grammar; and suggestions and potential solutions. Sixty percent reported that application and evaluation of APA style is a concern in their department. Content analysis identified four categories as proposed solutions: consistency, education, resources, and dialogue. On the basis of the feedback of the participants, the CRED program is proposed for the issues that were identified. Copyright 2009, SLACK Incorporated.

Alternative Polyadenylation Patterns for Novel Gene Discovery and Classification in Cancer

Directory of Open Access Journals (Sweden)

Oguzhan Begik

2017-07-01

Full Text Available Certain aspects of diagnosis, prognosis, and treatment of cancer patients are still important challenges to be addressed. Therefore, we propose a pipeline to uncover patterns of alternative polyadenylation (APA, a hidden complexity in cancer transcriptomes, to further accelerate efforts to discover novel cancer genes and pathways. Here, we analyzed expression data for 1045 cancer patients and found a significant shift in usage of poly(A signals in common tumor types (breast, colon, lung, prostate, gastric, and ovarian compared to normal tissues. Using machine-learning techniques, we further defined specific subsets of APA events to efficiently classify cancer types. Furthermore, APA patterns were associated with altered protein levels in patients, revealed by antibody-based profiling data, suggesting functional significance. Overall, our study offers a computational approach for use of APA in novel gene discovery and classification in common tumor types, with important implications in basic research, biomarker discovery, and precision medicine approaches.

Monthly sediment and interstitial water samples were collected in a shallow Chinese freshwater lake (Lake Donghu) from three areas to determine if alkaline phosphatase activity (APA) plays an important role, in phosphorus cycling in sediment. The seasonal variability in the kinetics of APA and other relevant parameters were investigated from 1995-1996. The phosphatase hydrolyzable phosphorus (PHP) fluctuated seasonally in interstitial water, peaking in the spring. A synchronous pattern was observed in chlorophyll a contents in surface water in general. The orthophosphate (o-P) concentrations in the interstitial water increased during the spring. An expected negative relationship between PHP and Vmax of APA is not evident in interstitial water. The most striking feature of the two variables is their co-occurring, which can be explained in terms of an induction mechanism. It is argued that phosphatase activity mainly contributes to the driving force of o-P regeneration from PHP in interstitial water, supporting the development of phytoplankton biomass in spring. The Vmax values in sediment increased during the summer, in conjunction with lower Km values in interstitial water that suggest a higher affinity for the substrate. The accumulation of organic matter in the sediment could be traced back to the breakdown of the algal spring bloom, which may stimulate APA with higher kinetic efficiency, by a combination of the higher Vmax in sediments plus lower Km values in interstitial water, in summer. In summary, a focus on phosphatase and its substrate in annual scale may provide a useful framework for the development of novel P cycling, possible explanations for the absence of a clear relationship between PHP and APA were PHP released from the sediment which induced APA, and the presence of kinetically higher APA both in sediment and interstitial water which permitted summer mineralization of organic matter derived from the spring bloom to occur. The study highlighted the

Ultraviolet Radiation (UVR) is a stressor for aquatic organisms affecting enzyme activities in planktonic populations because of the increase in reactive oxygen species. In addition, UVR exposure combined with other environmental factors (i.e. temperature and food quality) could have even higher detrimental effects. In this work, we aimed to determine the effect of UVR on somatic Alkaline Phosphatase Activity (APA) and Glutathione S-Transferase (GST) activity on the cladoceran Daphnia commutata under two different temperatures (10 °C and 20 °C) and under three food qualities (carbon:phosphorus ratios: 1150, 850 and 550). APA is a biomarker that is considered as a P deficiency indicator in zooplankton. Since recovery from UVR damage under dark conditions is an ATP depending reaction we also measured APA during recovery phases. We carried out a laboratory experiment combining different temperatures and food qualities with exposition to UVR followed by luminic and dark phases for recovery. In addition, we exposed organisms to H2O2, to establish if the response on APA to UVR was a consequence of the reactive oxygen species produced these short wavelengths. Our results showed that somatic APA was negatively affected by UVR exposure and this effect was enhanced under high temperature and low food quality. Consistently, GST activity was higher when exposed to UVR under both temperatures. The H2O2 experiments showed the same trend as UVR exposure, indicating that APA is affected mainly by oxidative stress than by direct effect of UVR on the enzyme. Finally, APA was affected in the dark phase of recovery confirming the P demands. These results enlighten the importance of food quality in the interacting effect of UVR and temperature, showing that C:P food ratio could determine the success or failure of zooplanktonic populations in a context of global change.

According to international recommendations [from the American College of Cardiology/American Heart Association/European Society of Cardiology] and those of the Haute Autorité de Santé (HAS) in France, treatment with a vitamin K antagonist is recommended in patients with atrial fibrillation (AF) in the presence of a high thromboembolic risk factor [history of stroke, transient ischemic attack, systemic embolism, or valvular heart disease, or presence of a mechanical heart valve prosthesis] or at least two moderate risk factors (age ≥75 years, hypertension, congestive heart failure, or diabetes). In patients with a major contraindication, the vitamin K antagonist can be replaced by an antiplatelet agent (APA). These recommendations are not systematically observed in patients with Alzheimer disease (AD). The aim of our study was to determine the factors associated with undertreatment of AF in geriatric outpatients with AD. Use of oral anticoagulants or APAs was studied in 66 patients with AF who were included in the French Network on Alzheimer Disease (REAL.FR) cohort, consisting of 686 outpatients living at home, supported by an informal caregiver, and suffering from Alzheimer-type dementia, with a Mini Mental Status Examination (MMSE) score between 10 and 26. First, demographic characteristics (age, sex, body mass index [BMI], living arrangements, educational level), medical conditions (comorbidity, number of medications), disability (activities of daily living [ADL], instrumental activities of daily living [IADL]), risk of falls (one-leg balance test), cognitive status (according to MMSE, Alzheimer's Disease Assessment Scale-Cognitive Subscale [ADAS-Cog], and Clinical Dementia Rating [CDR] scores), risk factors for stroke (hypertension, history of stroke, congestive heart failure, diabetes, or age ≥75 years) and potential contraindications to oral anticoagulants (OACs) or APAs (polypharmacy, risk of falls, renal failure, gastrointestinal diseases) of

Gernigon, Christophe; Pereira Dias, Catarina; Riou, François; Briki, Walid; Ninot, Grégory

2015-01-01

This study tested whether persons with Recent Spinal Cord Injury (RSCI) who practice adapted physical activities (APA) and those who do not differ with regard to achievement goals, physical self-perceptions, and global self-esteem. Adults with RSCI in rehabilitation centers voluntarily completed questionnaires of achievement goals and self-esteem. Then, based on whether they engaged or not in APA programs, they were considered participants or non-participants in APA. Compared to participants in APA, non-participants were more oriented toward mastery-avoidance goals and had lower scores of physical self-worth and global self-esteem. No differences were found for other achievement goals and for low-level dimensions of physical self. These findings suggest that mastery-avoidance goals are associated with a maladaptive motivational pattern when intrapersonal comparison conveys a threat for the self. Practical implications for rehabilitation programs for persons with RSCI are offered. Adapted Physical Activities (APA) programs are supervised physical activity programs in which the choice of the activity as well as the frequency, the duration, and the intensity of practice are adapted to the inpatients' capabilities. Attempts to master physical activities can be seen as threatening experiences to be avoided by persons with Recent Spinal Cord Injury (RSCI) in rehabilitation centers. Comparing one's capabilities in physical activities with those of other persons with RSCI is not motivationally detrimental with respect to the practice of these activities. Upon persons with RSCI' arrival in rehabilitation centers, physical educators should promote a friendly competitive climate in the practice of APA to help inpatients recover healthy levels of physical self-perceptions and global self-esteem as well as motivation to exercise.

Advanced paternal age (APA) is a risk factor for schizophrenia (Sz) and bipolar disorder (BP). Putative mechanisms include heritable genetic factors, de novo mutations, and epigenetic mechanisms. Few studies have explored phenotypic features associated with APA. The Genomic Psychiatry Cohort established a clinically characterized repository of genomic samples from subjects with a Sz-BP diagnosis or unaffected controls, 12,975 with parental age information. We estimated relative risk ratios for Sz, schizoaffective depressed and bipolar types (SA-D, SA-B), and BP with and without history of psychotic features (PF) relative to the control group, comparing each paternal age group to the reference group 20-24 years. All tests were two-sided with adjustment for multiple comparisons. Subjects with fathers age 45+ had significantly higher risk for all diagnoses except for BP w/o PF. APA also bore no significant relation to family psychiatric history. In conclusion, we replicated APA as a risk factor for Sz. To our knowledge, this is the first published report of APA in a BP sample stratified by psychosis history, extending this association only in BP w/PF. This suggests that phenotypic expression of the APA effect in Sz-BP spectrum is psychosis, per se, rather than other aspects of these complex disorders. The lack of a significant relationship between paternal age and familial disease patterns suggests that underlying mechanisms of the paternal age effect may involve a complex interaction of heritable and non-heritable factors. The authors discuss implications and testable hypotheses, starting with a focus on genetic mechanisms and endophenotypic expressions of dopaminergic function. © 2015 Wiley Periodicals, Inc. © 2015 Wiley Periodicals, Inc.

Diagnostic value of amplitude-phase analysis in myocardial infarct. Comparison with thallium perfusion scintigraphy and contrast ventrilography

The evaluation is based on the results of investigation of 34 patients who have had myocardial infarct without rhythm disturbances. Compared to contrast ventrilography, the amplitude-phase analysis (APA) of 'rest' radionuclide ventrilography show 80% sensitivity and 100% specificity, as well as high accuracy in determination of the type and localization of the kinetic disturbances. The comparison with the thallium perfusion scintigraphy demonstrates the possibility of APA to vizualize abnormal kinetic area of the myocardial wall and shows its independent significance in the cases of doubtful findings. APA is a powerful tool for unambigious differentiating of hypokinetic from akinetic and diskinetic areas. 1 tab., 1 fig., 4 refs

The Society for Industrial and Organizational Psychology (SIOP, Division 14 of the American Psychological Association [APA]) maintains Guidelines for Education and Training to provide guidance for the training of industrial-organizational (I-O) psychologists. The 2016/2017 revision combines separate documents for master's- and doctoral-level training into one document, because the competencies required for each degree are not very different. Instead, the degrees differ in breadth and depth. The updated Guidelines were approved as APA policy in August 2017. In this article, we briefly review the revision process and highlight the updates made in the latest version of the Guidelines. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

2001-12-01

It has been shown that injection of combinations of anti-aminopeptidase A (APA) monoclonal antibodies (mAb) that inhibit the enzyme activity induces an acute albuminuria in mice. This albuminuria is not dependent on inflammatory cells, complement, or the coagulation system. APA is an important regulator of the renin-angiotensin system because it is involved in the degradation of angiotensin II (Ang II). This study examined the potential role of glomerular Ang II in the induction of albuminuria. The relation among renal Ang II, glomerular APAX enzyme activity, and albuminuria was examined first. Injection of the nephritogenic combinations ASD-3/37 and ASD-37/41 in BALB/c mice induced albuminuria, whereas the non-nephritogenic combination ASD-3/41 had no effect. There was no clear relation between the inhibition of glomerular APA activity and albuminuria, yet it was evident that intrarenal Ang II levels were significantly increased in albuminuric mice and not in nonalbuminuric mice. As a next step, anti-APA mAb were administered to angiotensinogen-deficient mice that do not produce Ang II, and kidney morphology and albuminuria were determined. Angiotensinogen-deficient mice also developed albuminuria upon ASD-37/41 administration. Altogether, these findings clearly demonstrate that Ang II is not required for the induction of albuminuria upon injection of enzyme-inhibiting anti-APA mAb.

Asymmetry of Anticipatory Postural Adjustment During Gait Initiation

Directory of Open Access Journals (Sweden)

Hiraoka Koichi

2014-10-01

Full Text Available The purpose of this study was to investigate the asymmetry of anticipatory postural adjustment (APA during gait initiation and to determine whether the process of choosing the initial swing leg affects APA during gait initiation. The participants initiated gait with the leg indicated by a start tone or initiated gait with the leg spontaneously chosen. The dependent variables of APA were not significantly different among the condition of initiating gait with the preferred leg indicated by the start tone, the condition of initiating gait with the non-preferred leg indicated by the start tone, and the condition of initiating gait with the leg spontaneously chosen. These findings fail to support the view that the process of choosing the initial swing leg affects APA during gait initiation. The lateral displacement of the center of pressure in the period in which shifting the center of pressure to the initial swing phase before initiating gait with the left leg indicated by the external cue was significantly larger than that when initiating gait with the right leg indicated by the external cue, and significantly larger than that when initiating gait with the leg spontaneously chosen. Weight shift to the initial swing side during APA during gait initiation was found to be asymmetrical when choosing the leg in response to an external cue

Most experts agree that primary hyperaldosteronism (PHA) caused by an aldosterone-producing adenoma (APA) is best treated by adrenalectomy. From a public health standpoint, the cost of treatment must be considered. We sought to compare the current guideline-based (surgical) strategy with universal pharmacologic management to determine the optimal strategy from a cost perspective. A decision analysis was performed using a Markov state transition model comparing the strategies for PHA treatment. Pharmacologic management for all patients with PHA was compared with a strategy of screening for and resecting an aldosterone-producing adenoma. Success rates were determined for treatment outcomes based on a literature review. Medicare reimbursement rates were calculated to estimate costs from a third-party payer perspective. Screening for and resecting APAs was the least costly strategy in this model. For a reference patient with 41 remaining years of life, the discounted expected cost of the surgical strategy was $27,821. The discounted expected cost of the medical strategy was $34,691. The cost of adrenalectomy would have to increase by 156% to $22,525 from $8,784 for universal pharmacologic therapy to be less costly. Screening for APA is more costly if fewer than 9.6% of PHA patients have resectable APA. Resection of APAs was the least costly treatment strategy in this decision analysis model.

High-altitude peatlands of the Andes still remain relatively unexplored since most of the studies on carbon capture in tropical soils have focused on peatlands in low altitude areas, leaving aside the importance of the study of high mountain wetlands, currently called "bofedales" located between 3000 and 5000 masl, covering most of the Andes mountains in South America. These peatlands in turn may also represent important paleoclimatic records. In this study, we investigated three peatland cores (APA-01, APA2-01, and APA2-02) at different altitudes (4210 m, 4420 m and 4432 m, respectively) in high Andean Peatlands of southern Peru. The peatland studied is located at the headwater basin Cachi River, in the town of Ayacucho, Peru. The aim of this study was to evaluate the role played by past climatic changes on the peatlands carbon accumulation. Each core was sectioned centimeter by centimeter and sub samples (n = 31) were collected for radiocarbon dating by AMS (acceleration mass spectrometer) and were used to create a sedimentological model based on the program Clam2.2R. The concentrations of carbon and nitrogen were determined from a C / H / N elemental analyzer and the stable carbon and nitrogen isotopes (δ13C and δ15N) were also analyzed. The bulk density was determined based on the volume occupied by the sediment (g /cm3). Finally, the carbon accumulation rate (gC m-2año-1) was determined. The three cores were characterized by two sedimentary units, the results present in the first sedimentary unit of APA01 an average long-term carbon accumulation rate of 59 gC m-2año-1, APA2-01 with 32 gC m-2año-1 and finally APA2-02 with 24 gC m-2año-1; for the second sedimentary unit we have: APA01 on average 17 gC m-2año-1, APA2-01 with 33 gC m-2año-1 and finally APA2-02 with 49 gC m-2año-1. In conclusion, we can say that the carbon accumulation rate for the first sedimentary unit of the three cores decreases as the altitude increases; on the other hand, we have the
