Suicide attempt by self-poisoning: characteristics of suicide attempters seen at the Emergency Room at the University Hospital of the West Indies.

OBJECTIVE To document the characteristics of self-poisoning suicide attempters who were brought to the University Hospital of the West Indies (UHWI) Emergency Room and to outline the type of drug used in the attempt. METHOD This was a retrospective study conducted over the period 2005-2009. Data were gathered from patients' case records, log books and the hospital records using a questionnaire developed for this study. The questionnaire examined demographics, parameters of the drug ingested, patient's disposition, and reasons for attempt, final outcome and the type of discharge of patients who reported to the UHWI Emergency Room due to a suicide attempt by self-poisoning. RESULTS Over the five-year period, 127 cases of suicide attempt by self-poisoning were reported. Significantly more females than males presented to the hospital due to self-poisoning (3:1, chi2 = 33.37; p < 0.001). Of this amount, 96 cases (75.6%) were females and 31 (24.4%) were males. The age group most recorded was 16-30 years (70.8%). The most common reason for the suicide attempt was an interpersonal conflict (52%). The drug category most often used in self-poisoning was analgesics (52%) with acetaminophens being the most common (26.2%). CONCLUSION These findings are consistent with global suicide trends and indicate an urgent need to develop and implement national preventative and treatment measures for groups known to be at risk of suicidal attempts.
Assessment of Wear‐Related Features of the Kerf Wall from Saw Marks in Bone *†

Abstract: Analyses of saw marks in bone may yield important information about the class characteristics of saws used in postmortem dismemberments, yet little research has been directed at identifying saws’ individualizing characteristics. This study adds to existing saw mark analysis methodologies by examining wear‐related features of kerf walls using light‐ and environmental scanning electron microscopy. A crosscut saw and hacksaw were used to create sequences of 30 cuts in bone; these sequences reveal patterns of progressive loss of fine details of kerf wall morphology with increasing saw blade wear, because of the rounding of sharp points and edges. Nevertheless, diagnostic kerf wall features used to establish class characteristics persist despite these wear‐related changes. Unsuccessful attempts at statistical analysis of wear‐related changes, based on striae width and density, suggest these patterns are not readily quantifiable. Additionally, despite the scanning electron microscope’s superior imaging capabilities, it provided few practical, methodological gains over traditional light microscopy.
Dynamics of the Interaction of Human Apurinic Endonuclease (Ape1) with Its Substrate and Product*

We investigated the interaction dynamics of human abasic endonuclease, the Ape1 protein (also called Ref1, Hap1, or Apex), with its DNA substrate and incised product using electrophoretic assays and site-specific amino acid substitutions. Changing aspartate 283 to alanine (D283A) left 10% residual activity, contrary to a previous report, but complementation of repair-deficient bacteria by the D283A Ape1 protein was consistent with its activity in vitro. The D308A, D283/D308A double mutant, and histidine 309 to asparagine proteins had 22, 1, and ∼0.02% of wild-type Ape1 activity, respectively. Despite this range of enzymatic activities, all the mutant proteins had near-wild-type binding affinity specific for DNA containing a synthetic abasic site. Thus, substrate recognition and cleavage are genetically separable steps. Both the wild-type and mutant Ape1 proteins bound strongly to the enzyme incision product, an incised abasic site, which suggested that Ape1 might exhibit product inhibition. The use of human DNA polymerase β to increase Ape1 activity by eliminating the incision product supports this conclusion. Notably, the complexes of the D283A, D308A, and D283A/D308A double mutant proteins with both intact and incised abasic DNA were significantly more stable than complexes containing wild-type Ape1, which may contribute to the lower turnover numbers of the mutant enzymes. Wild-type Ape1 protein bound tightly to DNA containing a one-nucleotide gap but not to DNA with a nick, consistent with the proposal that substrate recognition by Ape1 involves a space bracketed by duplex DNA, rather than mere flexibility of the DNA.
Design and implementation of transmission system of initial haptic impression

This study proposes and implements a transmission system of haptic information employing the vision-based cutaneous sensor and the cutaneous display consists of electrotactile display. The proposed system can transmit not only kinesthetic but also spatially distributed tactile and thermal information. The implemented prototype system enabled a user to perceive the shape and material information of a remote object as the initial haptic impression.
Neutrophils Are Essential for Rapid Clearance of Enterococcus faecium in Mice

ABSTRACT A progressive increase in infections with multiresistant Enterococcus faecium has been reported, especially in cancer patients and neutropenic patients. Despite its increasing importance as a nosocomial pathogen, knowledge of the pathogenesis of E. faecium infections is highly limited. In this study, we investigated the role of neutrophils during peritonitis with subsequent bacteremia caused by E. faecium. Therefore, we depleted neutrophils by intraperitoneal injections of monoclonal antibody RB6-8C5. Mice were followed for 5 days, and the enterococcal outgrowth and inflammatory response were compared between neutropenic mice and immunoglobulin G-injected control mice. Neutropenic mice demonstrated a severe delay in enterococcal clearance from all cultured organs (peritoneal fluid, blood, and lung and liver tissue). In particular, neutropenic mice remained bacteremic for up to 3 days, whereas all nonneutropenic mice had cleared the bacteria from circulation by 2 days. Furthermore, neutropenic mice displayed elevated peritoneal cytokine and chemokine levels 1 day after the infection and attracted fewer macrophages into the peritoneal cavity. In the circulation, a prolonged elevation of tumor necrosis factor alpha, interleukin-6, and the acute-phase proteins serum amyloid A and complement 3 were measured in neutropenic mice. In conclusion, attraction of neutrophils to the primary site of E. faecium infection is important for a rapid clearance of this bacterium, thereby attenuating a systemic inflammatory response.
Local Lymph Node Data for the Evaluation of Skin Sensitization Alternatives: A Second Compilation

Background: Development, evaluation and validation of alternatives to skin sensitisation testing require the availability of reliable databases with which comparative analyses can be conducted to establish performance characteristics. To facilitate this we have published previously a database comprising results from local lymph node assays (LLNAs) conducted with 211 chemicals. That database embraced a substantial range of chemistry, and of relative skin sensitising potency, and has found application in the assessment of new or refined methods. Objective: In this paper we describe a second compilation to extend the LLNA database. Methods: This second data compilation was derived from previously conducted LLNA studies involving an additional 108 chemicals. In addition, the first database contained a small number of inaccuracies, affecting results recorded with a few chemicals. In this paper these have been corrected. Results: The inclusion of 108 new substances has served to extend and consolidate the areas of chemistry covered by the database. In addition, the entire dataset was evaluated for pre and prohaptens which will facilitate the choice of chemicals for alternative assay developments. Conclusions: It is anticipated that the new revised and extended database totalling over 300 chemicals will now serve as the primary resource to support the development and evaluation of new approaches to hazard identification and potency assessment.
Dextran sulfate triggers platelet aggregation via direct activation of PEAR1

Abstract Dextran sulfate (DxS; Mr 500 kD) induces fibrinogen receptor (αIIbβ3) activation via CLEC-2/Syk signaling and via a Syk-independent SFK/PI3K/Akt-dependent tyrosine kinase pathway in human and murine platelets. The platelet surface receptor, responsible for the DxS-induced Syk-independent Akt-activation, has hitherto not been identified. We found that DxS elicited a concentration-dependent aggregation of human platelets resulting from direct PEAR1 activation by DxS. Blocking the PEAR1 receptor, in combination with a selective Syk-inhibitor, completely abrogated the DxS-driven platelet aggregation. The DxS-induced Syk-phosphorylation was not affected in Pear1−/− platelets, but Akt-phosphorylation was largely abolished. As a result, the aggregation of Pear1−/− platelets was reduced and reversible, i.e. aggregates were less stable compared to wild-type platelet aggregates. Moreover, DxS-induced Pear1−/− platelet aggregation was fully abrogated by Syk inhibition, indicating that the remaining platelet aggregation of Pear1−/− platelets was Syk dependent. Hence, the Pear1/c-Src/PI3K/Akt- and CLEC-2/Syk-signaling pathways are independently and additively activated during platelet aggregation by DxS. Conclusion. The DxS-induced aggregation of human and murine platelets is the result of activation of PI3K/Akt through direct PEAR1 phosphorylation and parallel Syk-signaling through CLEC-2.
Longitudinal Study of Physical Activity and Sedentary Behavior in Children

OBJECTIVE: Physical activity is thought to decline during childhood, but the extent of the decline is unknown. We made objective measures of 2-year changes in physical activity and sedentary behavior in English children who participated in the Gateshead Millennium Study to explore the nature, timing, and extent of changes in physical activity and sedentary behavior before adolescence. METHODS: We conducted a longitudinal study of 405 children (207 girls), aged 7 years, in 2006/2007 and again 24 months later. Physical activity and sedentary behavior were measured with the Actigraph GT1M accelerometer. Data were analyzed in 2010. Changes in total volume of physical activity (accelerometer counts per minute [cpm]), moderate-to-vigorous–intensity physical activity (MVPA), and sedentary behavior were quantified. Factors associated with changes in physical activity and sedentary behavior were tested by using linear regression. Tracking of physical activity and sedentary behavior over the 2-year period was assessed by rank-order correlation. RESULTS: Mean daily volume of physical activity declined by 83 cpm (interquartile range [IQR]: −189 to 31) over 2 years; the percentage of daily time spent in MVPA was low at baseline and declined by 0.3% (IQR: −1.4 to 0.9). The percentage of daily time in sedentary behavior was high at baseline and increased from 78.0% to 81.1% of the day (change 3.1% [IQR: −0.3 to 6.0]). The decline in MVPA and increase in sedentary behavior were significantly greater in girls and in those with higher BMI z scores at baseline. Physical activity and sedentary behavior showed moderate tracking over the 2-year period. CONCLUSIONS: We report here new evidence of low and declining levels of physical activity and MVPA and increasing sedentary behavior before adolescence.
QoE-aware service delivery: A joint-venture approach for content and network providers

The objective of this work is the investigation of a possible collaboration between Over-The-Top (OTTs) service providers and Internet Service Providers (ISPs), which is centered around the Quality of Experience (QoE). Initially, we define a reference architecture with the required modules and interfaces for the interaction between the two providers. Then, we focus on the modeling of the revenue, whose maximization drives the collaboration. It is considered as depending on the user churn, which in turn is affected by the QoE and is modeled using the Sigmoid function. We illustrate simulation results based on our proposed collaboration approach which highlights how the proposed strategy increases the revenue generation and QoE for both players hence providing a ground for ISP to join the loop of revenue generation between OTT and users.
CPEB Interacts with an Ovary-specific eIF4E and 4E-T in Early Xenopus Oocytes*

CPEB (cytoplasmic polyadenylation element-binding protein) is an important regulator of translation in oocytes and neurons. Although previous studies of CPEB in late Xenopus oocytes involve the eIF4E-binding protein maskin as the key factor for the repression of maternal mRNA, a second mechanism must exist, since maskin is absent earlier in oogenesis. Using co-immunoprecipitation and gel filtration assays, we show that CPEB specifically interacts, via protein/protein interactions, with the RNA helicase Xp54, the RNA-binding proteins P100(Pat1) and RAP55, the eIF4E-binding protein 4E-T, and an eIF4E protein. Remarkably, these CPEB complex proteins have been characterized, in one or more organism, as P-body, maternal, or neuronal granule components. We do not detect interactions with eIF4E1a, the canonical cap-binding factor, eIF4G, or eIF4A or with proteins expressed late in oogenesis, including maskin, PARN, and 4E-BP1. The eIF4E protein was identified as eIF4E1b, a close homolog of eIF4E1a, whose expression is restricted to oocytes and early embryos. Although eIF4E1b possesses all residues required for cap and eIF4G binding, it binds m7GTP weakly, and in pull-down assays, rather than binding eIF4G, it binds 4E-T, in a manner independent of the consensus eIF4E-binding site, YSKEELL. Wild type and Y-A mutant 4E-T (which binds eIF4E1b but not eIF4E1a), when tethered to a reporter mRNA, represses its translation in a cap-dependent manner, and injection of eIF4E1b antibody accelerates meiotic maturation. Altogether, our data suggest that CPEB, partnered with several highly conserved RNA-binding partners, inhibits protein synthesis in oocytes using a novel pairing of 4E-T and eIF4E1b.
Adiponectin: a link between obesity and cancer

Adiponectin, an insulin-sensitising hormone produced by adipocytes, has direct antidiabetic, antiatherogenic, anti-inflammatory and antiangiogenic properties. Circulating adiponectin levels are lower in obesity, a disease state that is associated with certain malignancies. Recently, accumulating evidence suggests that adiponectin may have an important protective role in carcinogenesis. There is also evidence that at least some, if not most, cancer cell types express adiponectin receptors; thus adiponectin may act on tumour cells directly by binding and activating adiponectin receptors and downstream signalling pathways. Through its antiangiogenic properties, and also possibly through other mechanisms regulating cell proliferation discussed in this review, adiponectin may prove to be an effective novel anticancer agent. Large association and prospective studies to assess adiponectin levels in relation to risk from cancer, as well as mechanistic studies to prove adiponectin’s role in the development of malignancies, and interventional trials to address potential roles of adiponectin in cancer pathogenesis and therapeutics are needed.
Implementation of Resonant Controllers and Filters in Fixed-Point Arithmetic

Resonant controllers and filters are useful in voltage-source-converter control systems. Although the trend is toward implementation in floating-point arithmetic, fixed-point arithmetic is still of interest, but requires much greater care in the algorithm design. This paper covers some important issues, namely, choice of structure, design formulas, scaling, sensitivity, quantization-noise amplification, and suppression of overflow limit cycles. The results presented should be particularly helpful as design guidelines to practical engineers in a situation where one often resorts to trial and error.
Use of a Virtual Reality Physical Ride-On Sailing Simulator as a Rehabilitation Tool for Recreational Sports and Community Reintegration: A Pilot Study

ABSTRACTParticipation in sailing by people with disabilities, particularly in small sailboats, is widely regarded as having positive outcomes on self-esteem and general health for the participants. However, a major hurdle for people with no previous experience of sailing, even by those without disabilities, is the perception that sailing is elitist, expensive, and dangerous. Real-time “ride-on” sailing simulators have the potential to bridge the gap between dry-land and on-the-water sailing. These provide a realistic, safe, and easily supervised medium in which nonsailors can easily and systematically learn the required skills before venturing out on the water. The authors report a 12-wk pilot therapeutic sailing program using the VSail-Access sailing simulation system followed by on-water experience. After completion of the training, all subjects demonstrated the ability to navigate a simple course around marker buoys (triangular configuration) on the computer screen, the ability to sail independently in winds of moderate strength (up to 14 knots) on water, and measurable improvements in their psychologic health. In addition, the subjects were able to participate in a sports activity with their respective family members and experienced a sense of optimism about their future.
Epidemiology of Major Depressive Disorder in Iran: a Systematic Review and Meta-Analysis

Objectives: There are a large number of primary researches on the prevalence of major depressive disorder (MDD) in Iran; however, their findings are varied considerably. A systematic review was performed in order to summarize the findings. Methods: Electronic and manual searches in international and Iranian journals were conducted to find relevant studies reporting MDD prevalence. To maximize the sensitivity of the search, the references of relevant papers were also explored. We explored the potential sources of heterogeneity such as diagnostic tools, gender and other characteristics using meta-regression model. The combined mean prevalence rates were calculated for genders, studies using each type of instruments and for each province using meta-analysis method. Results: From 44 articles included in the systematic review, 24 reported current prevalence and 20 reported lifetime prevalence of MDD. The overall estimation of current prevalence of MDD was 4.1% (95% CI: 3.1-5.1). Women were 1.95 (95% CI: 1.55-2.45) times more likely to have MDD. The current prevalence of MDD in urban inhabitants was not significantly different from rural inhabitants. The analysis identified the variations in diagnostic tools as an important source of heterogeneity. Conclusions: Although there is not adequate information on MDD prevalence in some areas of Iran, the overall current prevalence of MDD in the country is high and females are at the greater risk of disease.
Discontinuidades y limitaciones de los últimos planes turísticos de España en relación a la sostenibilidad ambiental del turismo de sol y playa

El turismo de sol y playa es una actividad estrategica para la economia espanola que depende altamente de los recursos naturales que la posibilitan. Para garantizar su competitividad y su sostenibilidad futura es imprescindible la incorporacion de medidas ambientales en la politica turistica. El analisis critico argumentativo de los tres ultimos planes turisticos aprobados por el gobierno de Espana permite observar el alcance y las limitaciones de la incorporacion de tales medidas. Los poderes publicos reconocen la persistencia de los problemas ambientales pero esto no siempre se ha plasmado en los planes.
Long-term use of oral anticoagulants and the risk of fracture.

BACKGROUND Vitamin K participates in bone metabolism and, since oral anticoagulants antagonize vitamin K, their use may increase the risk of osteoporosis. OBJECTIVE To evaluate fracture risk at all skeletal sites following exposure to oral anticoagulants. METHODS In a population-based retrospective cohort study, 572 Olmsted County, Minnesota, women 35 years or older at their first lifetime venous thromboembolism event between 1966 and 1990 were followed up for fractures. Risk was assessed by comparing new fractures with the number expected from sex- and age-specific fracture incidence rates for the general population (standardized incidence ratio [SIR]). RESULTS Altogether, 480 fractures occurred during 6314 person-years of follow-up. Increasing exposure to oral anticoagulation was associated with an increased SIR for vertebral fractures: at less than 3 months of exposure, 2.4 (95% confidence interval [CI], 1.6-3.4); 3 to less than 12 months, 3.6 (95% CI, 2.5-4.9); and 12 months or more, 5.3 (95% CI, 3.4-8.0); and for rib fractures: at less than 3 months, 1.6 (95% CI, 0.9-2.7); 3 to less than 12 months, 1.6 (95% CI, 0.9-2.6); and 12 months or more, 3.4 (95% CI, 1.8-5.7). The data revealed no increased risk for other types of fractures. Oral anticoagulation for 12 months or more was an independent predictor of vertebral fractures (P = .009) and rib fractures (P = .02), but not other fractures. CONCLUSIONS Long-term exposure to oral anticoagulation is associated with an increased risk of vertebral and rib fractures. The mechanism by which this occurs is still unclear and needs further investigation.
