Abstract
Puromycin-sensitive aminopeptidases are found across phyla and are known to regulate the cell-cycle and play a protective role in neurodegenerative disease. PAM-1 is a puromycin-sensitive aminopeptidase important for meiotic exit and polarity establishment in the one-cell Caenorhabditis elegans embryo. Despite conservation of this aminopeptidase, little is known about its targets during development. In order to identify novel interactors, we conducted a suppressor screen and isolated four suppressing mutations in three genes that partially rescued the maternal-effect lethality of pam-1 mutants. Suppressed strains show improved embryonic viability and polarization of the anterior–posterior axis. We identified a missense mutation in wee-1.3 in one of these suppressed strains. WEE-1.3 is an inhibitory kinase that regulates maturation promoting factor. Although the missense mutation suppressed polarity phenotypes in pam-1, it does so without restoring centrosome–cortical contact or altering the cortical actomyosin cytoskeleton. To see if PAM-1 and WEE-1.3 interact in other processes, we examined oocyte maturation. Although depletion of wee-1.3 causes sterility due to precocious oocyte maturation, this effect was lessened in pam-1 worms, suggesting that PAM-1 and WEE-1.3 interact in this process. Levels of WEE-1.3 were comparable between wild-type and pam-1 strains, suggesting that WEE-1.3 is not a direct target of the aminopeptidase. Thus, we have established an interaction between PAM-1 and WEE-1.3 in multiple developmental processes and have identified suppressors that are likely to further our understanding of the role of puromycin-sensitive aminopeptidases during development.

Abstract
Morphogenesis involves coordinated cell migrations and cell shape changes that generate tissues and organs, and organize the body plan. Cell adhesion and the cytoskeleton are important for executing morphogenesis, but their regulation remains poorly understood. As genes required for embryonic morphogenesis may have earlier roles in development, temperature-sensitive embryonic-lethal mutations are useful tools for investigating this process. From a collection of ∼200 such Caenorhabditis elegans mutants, we have identified 17 that have highly penetrant embryonic morphogenesis defects after upshifts from the permissive to the restrictive temperature, just prior to the cell shape changes that mediate elongation of the ovoid embryo into a vermiform larva. Using whole genome sequencing, we identified the causal mutations in seven affected genes. These include three genes that have roles in producing the extracellular matrix, which is known to affect the morphogenesis of epithelial tissues in multicellular organisms: the rib-1 and rib-2 genes encode glycosyltransferases, and the emb-9 gene encodes a collagen subunit. We also used live imaging to characterize epidermal cell shape dynamics in one mutant, or1219ts, and observed cell elongation defects during dorsal intercalation and ventral enclosure that may be responsible for the body elongation defects. These results indicate that our screen has identified factors that influence morphogenesis and provides a platform for advancing our understanding of this fundamental biological process.

Abstract
This article distinguished particular members of the deaf-blind population as needing additional support to secure and maintain employment. Supported employment is examined and offered as an appropriate vehicle for providing this needed support. The currently held models of supported employment are described in detail as they pertain to this population, and the individual placement model is highlighted as perhaps the best choice for many persons with deaf-blindness. Finally, issues surrounding supported employment are provided and examined to raise questions for further exploration.

Abstract
Although there have been many developments related to specific strategies for treating patients after poisoning exposures, the mainstay of therapy remains symptomatic and supportive care. One of the most aggressive supportive modalities is extracorporeal membrane oxygenation (ECMO). Our goal was to describe the use of ECMO for toxicological exposures reported to the American College of Medical Toxicology (ACMT) Toxicology Investigators Consortium (ToxIC). We performed a retrospective review of the ACMT ToxIC Registry from January 1, 2010 to December 31, 2013. Inclusion criteria included patients aged 0 to 89 years, evaluated between January 2010 through December 2013, and received ECMO for toxicological exposure. There were 26,271 exposures (60 % female) reported to the ToxIC Registry, 10 (0.0004 %) received ECMO: 4 pediatric (< 12 years), 2 adolescent (12-18 years), and 4 adults (>18 years). Time of initiation of ECMO ranged from 4 h to 4 days, with duration from 15 h to 12 days. Exposures included carbon monoxide/smoke inhalation (2), bitter almonds, methanol, and several medications including antihistamines (2), antipsychotic/antidepressant (2), cardiovascular drugs (2), analgesics (2), sedative/hypnotics (2), and antidiabetics (2). Four ECMO patients received cardiopulmonary resuscitation (CPR) during their hospital course, and the overall survival rate was 80 %. ECMO was rarely used for poisoning exposures in the ACMT ToxIC Registry. ECMO was utilized for a variety of ages and for pharmaceutical and non-pharmaceutical exposures. In most cases, ECMO was administered prior to cardiovascular failure, and survival rate was high. If available, ECMO may be a valid treatment modality.

Abstract
The adult Caenorhabditis elegans hermaphrodite gonad consists of two mirror-symmetric U-shaped arms, with germline nuclei located peripherally in the distal regions of each arm. The nuclei are housed within membrane cubicles that are open to the center, forming a syncytium with a shared cytoplasmic core called the rachis. As the distal germline nuclei progress through meiotic prophase, they move proximally and eventually cellularize as their compartments grow in size. The development and maintenance of this complex and dynamic germline membrane architecture are relatively unexplored, and we have used a forward genetic screen to identify 20 temperature-sensitive mutations in 19 essential genes that cause defects in the germline membrane architecture. Using a combined genome-wide SNP mapping and whole genome sequencing strategy, we have identified the causal mutations in 10 of these mutants. Four of the genes we have identified are conserved, with orthologs known to be involved in membrane biology, and are required for proper development or maintenance of the adult germline membrane architecture. This work provides a starting point for further investigation of the mechanisms that control the dynamics of syncytial membrane architecture during adult oogenesis.

Abstract
OBJECTIVES The aim of this systematic review was to examine the epidemiology of malpractice claims in primary care. DESIGN A computerised systematic literature search was conducted. Studies were included if they reported original data (≥10 cases) pertinent to malpractice claims, were based in primary care and were published in the English language. Data were synthesised using a narrative approach. SETTING Primary care. PARTICIPANTS Malpractice claimants. PRIMARY OUTCOME Malpractice claim (defined as a written demand for compensation for medical injury). We recorded: medical misadventure cited in claims, missed/delayed diagnoses cited in claims, outcome of claims, prevalence of claims and compensation awarded to claimants. RESULTS Of the 7152 articles retrieved by electronic search, a total of 34 studies met the inclusion criteria and were included in the narrative analysis. Twenty-eight studies presented data from medical indemnity malpractice claims databases and six studies presented survey data. Fifteen studies were based in the USA, nine in the UK, seven in Australia, one in Canada and two in France. The commonest medical misadventure resulting in claims was failure to or delay in diagnosis, which represented 26-63% of all claims across included studies. Common missed or delayed diagnoses included cancer and myocardial infarction in adults and meningitis in children. Medication error represented the second commonest domain representing 5.6-20% of all claims across included studies. The prevalence of malpractice claims in primary care varied across countries. In the USA and Australia when compared with other clinical disciplines, general practice ranked in the top five specialties accounting for the most claims, representing 7.6-20% of all claims. However, the majority of claims were successfully defended. CONCLUSIONS This review of malpractice claims in primary care highlights diagnosis and medication error as areas to be prioritised in developing educational strategies and risk management systems.

Abstract
Kinins are vasoactive peptides that play important roles in cardiovascular homeostasis, pain and inflammation. After release from their precursor kininogens, kinins or their C-terminal des-Arg metabolites activate two distinct G protein-coupled receptors (GPCR), called B2 (B2R) or B1 (B1R). The B2R is expressed constitutively with a wide tissue distribution. In contrast, the B1R is not expressed under normal conditions but is upregulated by tissue insult or inflammatory mediators. The B2R is considered to mediate many of the acute effects of kinins while the B1R is more responsible for chronic responses in inflammation. Both receptors can couple to Galphai and Galphaq families of G proteins to release mediators such as nitric oxide (NO), arachidonic acid, prostaglandins, leukotrienes and endothelium-derived hyperpolarizing factor and can induce the release of other inflammatory agents. The focus of this review is on the different transduction events that take place upon B2R and B1R activation in human endothelial cells that leads to generation of NO via activation of different NOS isoforms. Importantly, B2R-mediated eNOS activation leads to a transient ( approximately 5min) output of NO in control endothelial cells whereas in cytokine-treated endothelial cells, B1R activation leads to very high and prolonged ( approximately 90min) NO production that is mediated by a novel signal transduction pathway leading to post-translational activation of iNOS.

Abstract
OBJECTIVES On graduation, UK dentists wishing to advance their career enter two years of general professional training aimed at consolidating their undergraduate experience. The Membership of the Faculty of Dental Surgery examination (MFDS) attests to its successful completion and is a pre-requisite for entry into training programmes which lead to specialist status. Most MFDS candidates prepare for the examination on their own while in full-time employment and many reinforce this self-directed learning with participation in short revision courses or through distance learning. Here we seek to obtain data on the specific educational needs of these individuals. METHODS Questionnaires were used to interrogate 92 UK graduates attending short MFDS revision courses of up to 1 week's duration to identify which topic areas were perceived as particular areas of weakness. To gain greater insight into the responses obtained, 18/92 respondents were selected at random and followed up with semi-structured interviews informed by the questionnaires. RESULTS Basic medical science, human diseases, law and ethics and health and safety regulations were the areas of weakness most frequently highlighted by the respondents. Most had undergone comprehensive courses in the first two topics; however, the interviews suggested that this was generally in the early stages of undergraduate training when they had difficulty in contextualising large quantities of new information. In the case of the latter two, teaching had been very varied and several interviewees felt that it had been inadequate. CONCLUSION Recent graduates preparing for MFDS have clear educational needs. These data have begun to characterise the requirements of this group and may inform the planning of short revision courses designed to assist them.

Abstract
The Daly River (catchment 53,000 km2) has the largest flow of all rivers in the Northern Territory and, due to the vast underground aquifers supplying the river, reliable flows of water and areas of high potential soils, is the centre of a region where water resource and agricultural development is being given serious consideration. As part of a larger assessment of environmental flow requirements, an inventory and risk assessment of water dependent ecosystems (wetlands) was undertaken for the Daly basin, a limestone dominated region, 19,382 km2 in size, located in the centre of the catchment. The assessment utilized geographic information system technology to collate, interrogate and analyse soil and topographic data that had been collected previously for the purpose of land capability analysis. The aggregated data were used as a surrogate for mapping the distribution of wetlands in the Daly basin. The land units mapped were composed of individual areas within which the soil, vegetation and landform exhibited a uniform pattern on aerial photographs. The wetland features mapped were classified using landform and hydroperiod as a basis and, to assist in the classification process, a ground-truthing exercise and a basin-wide low-level aerial survey were conducted.

Abstract
Following the amalgamation on one site of inpatient oral and maxillofacial surgical (OMFS) services serving four towns, patients attending accident and emergency (A and E) departments in Bolton, Burnley and Bury who required specialist OMFS care were transferred to Blackburn. This sometimes led to inappropriate transfer, with inconvenience for patients, sub-standard care and wasted resources. To reduce these problems, a videoconferencing system was established, linking the A and E departments of three peripheral hospitals to the central site. This allowed realtime visualization of patients and their radiographs, discussion between clinicians and transfer of a summary data-sheet. The aim was to improve remote diagnosis and to deliver a cost-effective, high-quality specialist service. In the first 12 months, there were an average of 25 remote consultations per month, with favourable feedback from both patients and clinicians.

Abstract
STUDY DESIGN A case-control study involving parallel benchmarking audits was conducted. OBJECTIVE To compare the safety, efficacy, and cost effectiveness of evidence-based medical care and usual care for acute low back pain. SUMMARY OF BACKGROUND DATA Although several sets of guidelines have been promoted for the management of acute low back pain, there is no evidence that following guidelines results in better outcomes. METHODS Special clinics were established, at which trained medical practitioners managed patients with acute low back pain according to evidence-based guidelines. Their outcomes were audited by independent research nurses. Meanwhile, and separately, the outcomes of patients managed by their own general practitioners were audited by research nurses using the same instruments of assessment. RESULTS In both settings, patients showed remarkable degrees and rates of recovery, with low rates of recurrence. However, evidence-based medical care resulted in a significantly lower cost of treatment; a significantly greater reduction in pain, sustained at both 6 and 12 months; significantly fewer patients requiring continuing care at 3, 6, and 12 months; a significantly greater proportion of patients fully recovered at 12 months; and significantly greater proportions of patients rating their treatment as extremely helpful and offering positive, unsolicited comments about their treatment. CONCLUSIONS The immediate results from evidence-based care are marginally better than those from good usual care, but in the long term, evidence-based care achieves clinically and statistically significant gains, with fewer patients requiring continuing care and remaining in pain. Consumers approve of evidence-based care.

Abstract
The purpose of this study was to evaluate the use of rectal gluten challenge in the diagnosis of coeliac disease. A total of 103 patients with features suggestive of this diagnosis were prospectively enrolled into the study; a diagnosis of coeliac disease was based on strictly defined criteria used in judging the proximal jejunal biopsy. On that basis, 45 out of the 103 patients were deemed to have coeliac disease. A slurry of gluten powder in physiological saline was introduced into the rectum, and biopsies taken before and at 2 h or 4 h after the challenge were examined immunohistochemically by computerized image analysis. Cell counts were analysed by logistic regression, and the best equations were obtained for each challenge group. The 2 h challenge yielded diagnostic sensitivity and specificity of 69.6% and 78.6% respectively. The 4 h challenge provided sensitivity and specificity of 100% and 100% respectively. These results were compared with other clinical diagnostic predictors,including anti-endomysial antibodies, which yielded diagnostic sensitivity and specificity of 70% and 98% respectively. It is concluded that a 4 h rectal challenge is a highly sensitive means of identifying gluten-sensitized individuals, and would be of particular value in cases showing negative antibody screening or equivocal biopsy appearances.

Abstract
The recent discussion of evidence-based, adaptive treatment planning highlights the need for models for the prediction of courses of treatment response. We combine a dose-response model with growth curve modeling to determine dose-response relations for well-being, symptoms, and functioning. Hierarchical linear modeling was used to model each patient's expected course of improvement. The resulting predictions were cross-validated on two samples of psychotherapy outpatients. The results give further empirical support for the dose-response model and the phase model of psychotherapy as well as for the usefulness of patient treatment response profiling for individual treatment management.

Abstract
OBJECTIVE NOD mice exhibit at least 2 overlapping autoimmune diseases: autoimmune endocrinopathy (Type I, insulin dependent diabetes) and autoimmune exocrinopathy (Sjogren's syndrome, SS). To date, 18 chromosomal regions have been identified that contribute to development of diabetes in NOD mice; however, genetic mapping of similar susceptibility loci for autoimmune exocrinopathy is just beginning. We investigated if these 2 autoimmune diseases share a genetic predisposition. METHODS Congenic partner strains of NOD and C57BL/6 mice containing defined genetic intervals influencing susceptibility to diabetes (Idd) were screened for histological and biochemical markers for their effect on the development of SS-like disease. Saliva flow rates, protein concentration, amylase activity, and cysteine protease activity were evaluated. RESULTS In contrast to the nonsusceptible parental C57BL/6 strain, C57BL/6.NOD Idd5 congenic partner strain, containing a genetic region derived from chromosome 1 of the NOD mouse, exhibited pathophysiological characteristics of autoimmune exocrinopathy. Replacement of individual diabetes susceptibility intervals Idd3, Idd5, Idd13, Idd1, and Idd9, as well as a combination of the Idd3, Idd10, and Idd17 intervals, with resistance alleles had little effect on development of autoimmune exocrinopathy. Conversely, NOD mice, in which the chromosome regions containing both Idd5 and Idd3 have been replaced by intervals derived from C57BL mice, exhibit a reduced pathophysiology associated with SS-like autoimmune exocrinopathy. CONCLUSION Alleles on chromosomes 1 (Idd5) and 3 (Idd3) in combination appear to greatly influence susceptibility and resistance to development of autoimmune exocrinopathy. The association with certain Idd, but not other Idd loci, indicate that genetic overlap is present but probably not inclusive.

Abstract
Previous research on highly reflective multilayer optical coatings has shown that varying the thickness of layers from their traditional quarter-wave values gives the potential for greater damage thresholds without sacrificing the desired optical properties. We numerically investigate the influence of unintended layer thickness fluctuations in these nontraditional designs, concluding that such fluctuations should have minimal effect on the optical properties of the coating. This result makes the prospect of producing nontraditional designs more promising.

Abstract
BACKGROUND Single-fraction radiosurgery of acoustic neuromas less than 3 cm in diameter is remarkable for high control but not infrequent incidence of facial and trigeminal neuropathy. Larger tumors treated surgically often result in deafness and facial neuropathy. Fractionated stereotactic radiosurgery was used in an effort to maintain effective therapy while minimizing toxicity of treatment. METHODS The authors described 38 patients with acoustic neuromas, with age range 35-89 years (mean, 60 years). 2,000 cGy in divided weekly doses of 400 or 500 cGy was most commonly prescribed. Tumors > or = 3 cm (n = 16) received the 5 fraction schema. Mean tumor volume was 6.9 cm3, with range from 0.1 to 32.0 cm3. RESULTS Median clinical follow-up was 27.1 months, while neuroimaging follow-up had a median of 16.3 months. All tumors were controlled. Of 23 tumors smaller than 3 cm, 14 (61%) decreased in size, and 9 showed cessation of growth. Thirteen of 16 (81%) large acoustic neuromas (3-5 cm) diminished in size. The remaining 3 showed cessation of growth. Median radiographic follow-up was 20 months, with a median clinical follow-up of 28 months. No patient developed fifth nerve symptoms after treatment nor did any patient require surgery for treatment failure. Only one had temporary seventh nerve palsy. CONCLUSION Fractionated stereotactic radiosurgery offers a therapeutic approach producing high control rates while avoiding morbidity frequently seen after single-fraction radiosurgery or microsurgery.

Abstract
In the promoters of many immediate early genes, including c-fos, CArG DNA regulatory elements mediate basal constituitive expression and rapid and transient serum induction. CArG boxes also occur in the promoters of muscle-specific genes, including skeletal alpha-actin, where it confers muscle-specific expression. These elements are regulated, at least in part, by the ubiquitous transcription factors serum response factor (SRF) and YY1. The homeobox transcription factor Phox1/MHox has also been implicated in regulation of the c-fos CArG element and is thought to function by facilitating SRF binding to DNA. Here, we provide in vitro and in vivo evidence that the mechanism of YY1 repression of CArG elements results from competition with SRF for overlapping binding sites. We describe in detail the binding sites of YY1 and SRF through serial point mutations of the skeletal alpha-actin proximal CArG element and identify a mutation that dramatically reduces YY1 binding but retains normal SRF binding. YY1 competes with SRF for binding to wild-type CArG elements, but not to this point mutant in vitro. This mutant is sufficient for muscle-specific expression in vivo but is much less sensitive to repression by YY1 overexpression. We utilized the YY1/SRF competition to address the role of Phox1 at these elements. Phox1 overexpression did not diminish YY1-mediated repression, suggesting that transcriptional activation by Phox1 does not result from enhanced SRF binding to these elements. These methods may prove to be useful for assessing interactions between other CArG element regulatory factors.

Abstract
GATA factors constitute a family of transcriptional regulatory proteins expressed with distinct developmental and tissue-specific profiles and thought to regulate cell-restricted programs of gene expression. Here we describe the molecular cloning, chromosomal location, and transcription of the human GATA-6 gene. The GATA-6 cDNA encodes a predicted 449-amino-acid protein, which is highly conserved among vertebrates, and includes the two adjacent zinc-finger/basic domains characteristic of the GATA factor family. GATA-6 maps to human chromosome 18q11.1-q11.2 by fluorescence in situ hybridization. The gene is transcribed in a pattern overlapping that of GATA-4. Transcripts for both of these genes are prominent in heart, pancreas, and ovary, but only GATA-6 mRNA is found in lung and liver. GATA-6 transcripts are also detected in cultures of human and rat vascular smooth muscle cells (VSMCs). In VSMCs, GATA-6 transcripts are down- regulated when quiescent cultures are stimulated to proliferate in response to mitogen activation. These data demonstrate that GATA-6 is subject to both tissue-specific and mitogen-responsive regulatory signals. GATA-6 is a prime candidate for a gene that might regulate the differentiative state of VSMCs.

Abstract
The purpose of this study was to assess changes in parenting attitudes among high school students as an effect of a child abuse prevention unit taught in a required health class. Attitudes were measured using the Adult-Adolescent Parenting Inventory (AAPI), which was administered as a pretest-posttest. This was a primary prevention approach targeting students before they become parents. The unit consisted of an overview of child abuse, normal developmental expectations of children, anger management, and positive parenting techniques. Students from 4 schools participated in the study, and most students in the sample (N = 585) demonstrated healthy parenting attitudes. Low scores on multiple scales at pretest were recorded for 3.6% of the sample. Effect of intervention was measured using paired t tests, and a positive and statistically significant effect of intervention was noted, especially in 2 of 4 schools. Low-scoring students increased scores significantly although not up to mean pretest levels for the whole sample. Recommendations for further community health nursing research and educational initiatives are supported by these findings.

Abstract
The age-adjusted prevalence of peripheral arterial disease (PAD) in the U.S. population has been estimated to approach 12%. The clinical consequences of occlusive peripheral arterial disease (PAD) include pain on walking (claudication), pain at rest, and loss of tissue integrity in the distal limbs; the latter may ultimately lead to amputation of a portion of the lower extremity. Surgical bypass techniques and percutaneous catheter-based interventions may be used to successfully revascularize the limbs of certain patients with PAD. In many patients, however, the anatomic extent and distribution of arterial occlusion is too severe to permit relief of pain and/or healing of ischemic ulcers. No effective medical therapy is available for the treatment of such patients. The purpose of this clinical protocol is to document the safety of therapeutic angiogenesis achieved in this case by percutaneous catheter-based delivery of the gene encoding vascular endothelial growth factor (VEGF) in patients with PAD; and, as secondary objectives, investigate the bioactivity of this strategy to relieve rest pain and heal ischemic ulcers of the lower extremities. The rationale for this human protocol is based upon preclinical studies performed in a rabbit model of hindlimb ischemia. These studies are described in detail below and in the manuscripts enclosed in the Appendix to this proposal. In brief, a single intra-arterial bolus of VEGF recombinant human protein, delivered percutaneously to the ischemic limb via an intravascular catheter, resulted in angiographic, hemodynamic, physiologic, and histologic evidence of augmented collateral artery development. Subsequently, similar results were achieved using an angioplasty catheter with a hydrogel-coated balloon to deliver 400 micrograms of a plasmid containing the cDNA for VEGF to the internal iliac artery in the same animal model. Accordingly, we propose to administer arterial gene (VEGF) therapy to patients with rest pain and/or ischemic leg ulcers considered not to be candidates for conventional revascularization techniques. The dose of plasmid to be administered will be progressively escalated beginning with 500 micrograms for the first four patients, 1000 micrograms for the following six patients, 2000 micrograms for the third group of six patients, and 400 micrograms for the fourth group of six patients.

Abstract
The MEF2 family of transcription factors control the expression of muscle-specific and mitogen-induced genes. Here we describe the isolation and structure of the human MEF2A gene. The protein coding region of MEF2A is divided by 10 introns. The 3' untranslated region (UTR) is 3.7 kb in length, and it contains a region that is highly homologous with a portion of the 3' UTR of Xenopus MEF2A. A partially processed pseudogene (MEF2AP) corresponding to MEF2A was also isolated and characterized. Human MEF2A was mapped by fluorescence in situ hybridization to chromosome 15q26, and MEF2AP was mapped to chromosome 1q24 --> q25.
