Neutrophil migration is an essential step in leukocyte trafficking during inflammatory responses. Semaphorins, originally discovered as axon guidance cues in neural development, have been shown to regulate cell migration beyond the nervous system. However, the potential contribution of semaphorins in the regulation of neutrophil migration is not well understood. This study examines the possible role of a secreted chemorepellent, Semaphorin 3E (Sema3E), in neutrophil migration. In this study, we demonstrated that human neutrophils constitutively express Sema3E high-affinity receptor, PlexinD1...

Colorectal cancer (CRC) is a worldwide problem for public health. mutL homolog 1 (MLH1) is a key component of the mismatch repair system, and the MLH1-93G/A polymorphism (rs1800734) is predicted to affect MLH1 protein expression, suggesting that the polymorphism may be associated with the cancer risk; however, the results concerning this have been inconsistent. In order to investigate the possible correlation between human (h)MLH1-93G/A polymorphism and the development and progression of sporadic CRC (SCRC) in China, the genotypes of hMLH1-93G/A were detected by the TaqMan MGB probe method in 312 SCRC patients and 300 healthy controls, and immunohistochemical staining was also performed to measure the expression of hMLH1 in cases with different alleles among the SCRC patients and normal controls...

BACKGROUND AND PURPOSE: Patients presenting with an intracerebral hemorrhage (ICH) generally have an initial noncontrast computed tomography (NCCT) of the brain. Computed tomography angiography (CTA) can help identify secondary causes of ICH and detect a "spot sign." We hypothesized that performing an urgent CTA in the setting of a presumed primary ICH has only limited utility and did not alter urgent management. METHODS: This was a retrospective study of consecutive patients presenting with a primary ICH identified from the Duke University Stroke Registry from 2010 to 2013 who had an ICH detected on an initial NCCT...

BACKGROUND: The ability of a simple self-assessment tool for estimated functional capacity to predict long-term prognosis in patients with established peripheral artery disease (PAD) is unknown. We investigate whether subjective measurement of functional capacity estimated by using the Duke Activity Status Index (DASI) questionnaire predicts long-term prognosis in patients with established PAD. METHODS: We administered the DASI questionnaire to 771 stable patients with established PAD who underwent elective diagnostic coronary angiography with 5-year follow-up all-cause mortality...

BACKGROUND: Geographic variation in congenital heart disease is not well-described. This study uses geographic information systems (GIS) to describe the spatial epidemiology of tetralogy of Fallot (TOF), in North Carolina (NC) and to compare travel time for cases to congenital heart centers in NC. METHODS: Using the NC Birth Defects Monitoring Program database, live births with TOF born between 2003 and 2012 were identified. Birth certificates provided demographic variables...

Accurate representation of photosynthesis in terrestrial biosphere models (TBMs) is essential for robust projections of global change. However, current representations vary markedly between TBMs, contributing uncertainty to projections of global carbon fluxes. Here we compared the representation of photosynthesis in seven TBMs by examining leaf and canopy level responses of photosynthetic CO2 assimilation (A) to key environmental variables: light, temperature, CO2 concentration, vapor pressure deficit and soil water content...

Propolis samples from Kangaroo Island, South Australia, were investigated for chemical constituents using high-field nuclear magnetic resonance spectral profiling. A type of propolis was found containing a high proportion of prenylated hydroxystilbenes. Subsequently, the botanical origin of this type of propolis was identified using a beehive propolis depletion method and analysis of flora. Ligurian honey bees, Apis mellifera ligustica Spinola, were found to produce propolis from resin exuded by the Australian native sedge plant Lepidosperma sp...

Thrombotic microangiopathy has numerous causes and may result in chronic kidney disease with secondary glomerulosclerosis. Detailed analyses of this interplay of lesions have been lacking. Buob et al. report on their adult, mostly Caucasian patients, showing frequent sclerosis, most often of collapsing type, with worse prognosis than in those without segmental scars. The complex interplay of glomerular cells and possible ways in which the endothelial cells may talk back to the podocytes, and vice versa, are discussed...

When there have been substantial failures by institutional leadership in their oversight responsibility to protect research integrity, the public should demand that these be recognized and addressed by the institution itself, or the funding bodies. This commentary discusses a case of research failures in developing genomic predictors for cancer risk assessment and treatment at a leading university. In its review of this case, the Office of Research Integrity, an agency within the US Department of Health and Human Services, focused their report entirely on one individual faculty member and made no comment on the institution's responsibility and its failure to provide adequate oversight and investigation...

This participant outcome evaluation serves as a preliminary investigation into the effects of lectio divina, a chaplaincy service representing a form of focused Scripture reading. A sample of n = 19 patients who participated in this service at a Department of Veterans Affairs Medical Center in upstate New York was screened at baseline and 30-days follow-up using the Duke University Religion Index, Berg Spiritual Injury Scale, and a screening question for thoughts of harming self or others. These measures were used to assess the intended outcomes of enhanced religiosity, ameliorated spiritual injury, and decreased thoughts of violence...

International research is an essential means of reducing health disparities between and within countries and should do so as a matter of global justice. Research funders from high-income countries have an obligation of justice to support health research in low and middle-income countries (LMICs) that furthers such objectives. This paper investigates how their current funding schemes are designed to incentivise health systems research in LMICs that promotes health equity. Semi-structured in-depth interviews were performed with 16 grants officers working for 11 funders and organisations that support health systems research: the Alliance for Health Policy and Systems Research, Comic Relief, Doris Duke Foundation, European Commission, International Development Research Centre, Norwegian Agency for Development Cooperation, Research Council of Norway, Rockefeller Foundation, UK Department of International Development, UK Medical Research Council, and Wellcome Trust...

I joined The Hastings Center this past summer, after graduating from Duke University, where I researched advancements in neuroscience and genomics and their import for law, ethics, and policy. This research required, to an extent, faith in the idea that researchers can identify pathways by which genes combine with epigenetic and environmental factors to affect neuronal activity and influence behaviors. Throughout my first months here, I have puzzled over broad critiques of "genomic hype" in recent literature, which clash with the optimistic rhetoric found in the Human Genome Project and the Precision Medicine Initiative...

The increasing debate and restrictions on primate research have prompted many surveys about their status. However, there is a lack of information regarding strepsirrhine primates in the literature. This study provides an overview of research on strepsirrhines in captivity by analyzing scientific articles published from 2010 to 2013 and assessing publicly available government reports in Europe and the United States. Data on taxonomy, country, research area, research class, and type of institution were extracted...
