Temperature Assessment on a Reclaimed Surface Mine During Northern Bobwhite Breeding Season: Considerations for Habitat Management

Ground-level air temperatures were assessed within 4 distinct habitat areas on a managed reclaimed surface mine at Peabody Wildlife Management Area, Kentucky, 26 June–17 July 2015, during the northern bobwhite (Colinus virginianus) brood season. Habitat consisted of disked and nondisked areas of native grass and an invasive species, sericea lespedeza (Lespedeza cuneata). Disked areas offered more open space for bobwhite mobility and experienced higher average temperatures than nondisked sites. Although statistically significant, differences in air temperature between disked and nondisked areas were likely too small to have practical implications for bobwhite habitat management in Kentucky under current climatic conditions. This will likely change in the future as the regional climate warms and periods of excessive heat are more likely to occur. Consequently, managers may want to consider microclimate when making management decisions

Differences in NT-proBNP Response and Prognosis in Men and Women With Heart Failure With Reduced Ejection Fraction.

Background NT-proBNP (N-terminal pro-B-type natriuretic peptide) is a prognostic biomarker in heart failure (HF) with reduced ejection fraction. However, it is unclear whether there is a sex difference in NT-proBNP response and whether the therapeutic goal of NT-proBNP ≤1000 pg/mL has equivalent prognostic value in men and women with HF with reduced ejection fraction. Methods and Results In a secondary analysis of the GUIDE-IT (Guiding Evidence Based Therapy Using Biomarker Intensified Treatment) trial we analyzed trends in NT-proBNP and goal attainment by sex. Differences in clinical characteristics, HF treatment, and time to all-cause death or HF hospitalization were compared. Landmark analysis at 3 months determined the prognostic value of early NT-proBNP goal achievement in men and women. Of the 286 (32%) women and 608 (68%) men in the GUIDE-IT trial, women were more likely to have a nonischemic cause and shorter duration of HF. Guideline-directed medical therapy was less intense over time in women. The absolute NT-proBNP values were consistently lower in women; however, the change in NT-proBNP and clinical outcomes were similar. After adjustment, women achieving the NT-proBNP goal had an 82% reduction in death or HF hospitalization compared with a 59% reduction in men. Conclusions Men and women with HF with reduced ejection fraction had a similar NT-proBNP response despite less intensive HF treatment among women. However, compared with men, the early NT-proBNP goal of ≤1000 pg/mL had greater prognostic value in women. Future efforts should be aimed at intensifying guideline-directed medical therapy in women, which may result in greater NT-proBNP reductions and improved outcomes in women with HF with reduced ejection fraction.

Plasma Levels of Inter-α Inhibitor Proteins in Children with Acute Dengue Virus Infection

Background: Inter-α inhibitor proteins (IaIp) belong to a family of protease inhibitors that are involved in the haemostatic and the vascular system. Dengue viruses (DENV) infections are characterized by coagulopathy and increased vascular permeability. In this study we measured the concentration of IaIp during DENV infections and evaluated its potential as a biomarker. Methods and Findings: Concentrations of IaIp were measured in patients with acute DENV infections using a quantitative, competitive enzyme linked immunoassay. Concentrations of IaIp measured in pediatric patients suffering from severe DENV infections were significantly lower than in healthy controls. Conclusions: This is the first report to demonstrate changes in concentration of IaIp during viral infections. The data also highlight the potential of IaIp as a biological marker for severity of DENV infections

Riverine sustainment 2012

Student Integrated ProjectIncludes supplementary materialThis technical report analyzed the Navy's proposed Riverine Force (RF) structure and capabilities for 2012. The Riverine Sustainment 2012 Team (RST) examined the cost and performance of systems of systems which increased RF sustainment in logistically barren environments. RF sustainment was decomposed into its functional areas of supply, repair, and force protection. The functional and physical architectures were developed in parallel and were used to construct an operational architecture for the RF. The RST used mathematical, agent-based and queuing models to analyze various supply, repair and force protection system alternatives. Extraction of modeling data revealed several key insights. Waterborne heavy lift connectors such as the LCU-2000 are vital in the re-supply of the RF when it is operating up river in a non-permissive environment. Airborne heavy lift connectors such as the MV-22 were ineffective and dominated by the waterborne variants in the same environment. Increase in manpower and facilities did appreciable add to the operational availability of the RF. Mean supply response time was the biggest factor effecting operational availability and should be kept below 24 hours to maintain operational availability rates above 80%. Current mortar defenses proposed by the RF are insufficient.N

Outcomes of Anatomical versus Functional Testing for Coronary Artery Disease

BACKGROUND: Many patients have symptoms suggestive of coronary artery disease (CAD) and are often evaluated with the use of diagnostic testing, although there are limited data from randomized trials to guide care. METHODS: We randomly assigned 10,003 symptomatic patients to a strategy of initial anatomical testing with the use of coronary computed tomographic angiography (CTA) or to functional testing (exercise electrocardiography, nuclear stress testing, or stress echocardiography). The composite primary end point was death, myocardial infarction, hospitalization for unstable angina, or major procedural complication. Secondary end points included invasive cardiac catheterization that did not show obstructive CAD and radiation exposure. RESULTS: The mean age of the patients was 60.8±8.3 years, 52.7% were women, and 87.7% had chest pain or dyspnea on exertion. The mean pretest likelihood of obstructive CAD was 53.3±21.4%. Over a median follow-up period of 25 months, a primary end-point event occurred in 164 of 4996 patients in the CTA group (3.3%) and in 151 of 5007 (3.0%) in the functional-testing group (adjusted hazard ratio, 1.04; 95% confidence interval, 0.83 to 1.29; P = 0.75). CTA was associated with fewer catheterizations showing no obstructive CAD than was functional testing (3.4% vs. 4.3%, P = 0.02), although more patients in the CTA group underwent catheterization within 90 days after randomization (12.2% vs. 8.1%). The median cumulative radiation exposure per patient was lower in the CTA group than in the functional-testing group (10.0 mSv vs. 11.3 mSv), but 32.6% of the patients in the functional-testing group had no exposure, so the overall exposure was higher in the CTA group (mean, 12.0 mSv vs. 10.1 mSv; P<0.001). CONCLUSIONS: In symptomatic patients with suspected CAD who required noninvasive testing, a strategy of initial CTA, as compared with functional testing, did not improve clinical outcomes over a median follow-up of 2 years.

Arsenic Trioxide Enhances the Radiation Sensitivity of Androgen-Dependent and -Independent Human Prostate Cancer Cells

Prostate cancer is the most common malignancy in men. In the present study, LNCaP (androgen-sensitive human prostate cancer cells) and PC-3 cells (androgen-independent human prostate cancer cells) were used to investigate the anti-cancer effects of ionizing radiation (IR) combined with arsenic trioxide (ATO) and to determine the underlying mechanisms in vitro and in vivo. We found that IR combined with ATO increases the therapeutic efficacy compared to individual treatments in LNCaP and PC-3 human prostate cancer cells. In addition, combined treatment showed enhanced reactive oxygen species (ROS) generation compared to treatment with ATO or IR alone in PC-3 cells. Combined treatment induced autophagy and apoptosis in LNCaP cells, and mainly induced autophagy in PC-3 cells. The cell death that was induced by the combined treatment was primarily the result of inhibition of the Akt/mTOR signaling pathways. Furthermore, we found that the combined treatment of cells pre-treated with 3-MA resulted in a significant change in AO-positive cells and cytotoxicity. In an in vivo study, the combination treatment had anti-tumor growth effects. These novel findings suggest that combined treatment is a potential therapeutic strategy not only for androgen-dependent prostate cancer but also for androgen-independent prostate cancer

An organizational justice perspective to task-and person-focused counterproductive work behaviors towards individuals.

The authors investigated the relationship between organizational justice and counterproductive work behaviors directed towards individuals (CWBI) to understand if the two behaviors of task-focused and person-focused CWBIs exist within the domain of CWBI. A total of 143 working adults from various industries were surveyed. Regression analysis revealed non-significant relationships between distributive, procedural and interactional justice and task- and person- focused CWBIs. Hence, the hypothesized composite structure of CWBI could not be proven. An additional regression analysis and a further t-test analysis revealed a marginally significant interactional effect between interactional and distributive justice with respect to task-focused CWBI and significant differences between male and female CWBI scores respectively. The marginally significant interactional relationship emphasizes the importance of interactional justice in the workplace, thereby providing reasons for managers to ensure respectful treatment of employees. Lastly, possible theoretical explanations for the non-significant findings and future research directions are proposed at the end of the paper.BUSINES
