Understanding nest site choice by chimpanzees has implications for ecology, anthropology, and in the collection of census data, yet it remains controversial. Here we provide the first information on environmental factors affecting nest site choice in a montane population of the rare and relatively understudied Nigerian/Cameroon chimpanzee (Pan troglodytes ellioti) in Ngel Nyaki Forest Reserve, Nigeria. The forest is small, isolated, and visited by researchers, community members, and hunters. We also tested the hypothesis that people (researchers) walking along forest trails collecting data on a regular basis since 2005 will have changed nesting behaviour in the vicinity of the trails...

: TNF-related apoptosis inducing ligand (TRAIL) is a potent death-inducing ligand that mediates apoptosis through the extrinsic pathway and serves as an important endogenous tumor suppressor mechanism. Because tumor cells are often killed by TRAIL and normal cells are not, drugs that activate the TRAIL pathway have been thought to have potential clinical value. However, to date, most TRAIL-related clinical trials have largely failed due to the tumor cells having intrinsic or acquired resistance to TRAIL-induced apoptosis...

BACKGROUND: The interleukin-17 (IL-17) cytokine pathway plays a key role in the development of psoriasis. Antibodies targeting IL-17 or blocking its receptor may be a new therapeutic approach for psoriasis. To assist treatment selection in daily practice it is essential to understand the benefit and risk profile of IL-17 antagonists. OBJECTIVE: We performed a meta-analysis to evaluate the efficacy and safety of IL-17 antagonists in patients with psoriasis. METHODS: We searched a number of databases for relevant randomized clinical trials (RCTs) published before May 2016...

White matter (WM) degeneration has been found during the course of cognitive decline in both Alzheimer's disease (AD) and amnestic mild cognitive impairment (aMCI), however, it is unclear whether there are different WM microstructural abnormalities between two subtypes of aMCI, including single domain aMCI (aMCI-s) and multiple domain aMCI (aMCI-m). Thirty-two patients of aMCI single-domain (aMCI-s), twenty-three patients of aMCI multiple-domain (aMCI-m) and twenty-three healthy normal controls (NC) participated in this study...

BACKGROUND: Freezing of gait (FOG) affects approximately 50% of people with Parkinson Disease (PD), impacting quality of life and placing financial and emotional strain on the individual and caregivers. People with PD and FOG have similar deficits in motor adaptation and cognition as individuals with cerebellar lesions, indicating the cerebellum may play a role in FOG. OBJECTIVE: To examine potential differences in cerebellar volumes and their relationships with cognition between PD with (FOG+) and without FOG (FOG-)...

Chemotherapy-induced cancer cell secretomes promote resistance due, in part, to a predominant glycolytic energy metabolism, which drives aggressive cancer cell proliferation. However, the characterization of these secretomes and the molecular events that associate them with acquired drug resistance remain poorly understood. In this study, we show that secretomes of cancer cells with high-level paclitaxel resistance stimulated cell proliferation and suppressed drug-induced apoptosis of drug-sensitive cells. We also found that drug (docetaxel)-stimulated induction of interferon-α (IFN-α), IFN-λ and tumor necrosis factor-α (TNF-α) release in drug-sensitive cells was lowered by these secretomes...

Hepatitis C virus (HCV)-specific CD4+ and CD8+ T cells are key to successful viral clearance in HCV disease. Accumulation of exhausted HCV-specific T cells during chronic infection results in considerable loss of protective functional immune responses. The role of T-cell exhaustion in chronic HCV disease remains poorly understood. Here, we studied the frequency of HCV peptide-stimulated T cells expressing negative immune checkpoints (PD-1, CTLA-4, TRAIL, TIM-3 and BTLA) by flow cytometry, and measured the levels of Th1/Th2/Th17 cytokines secreted by T cells by a commercial Multi-Analyte ELISArray™ following in vitro stimulation of T cells using HCV peptides and phytohemagglutinin (PHA)...

Autophagy, a catabolic process by which cytoplasmic components are degraded in lysosomes, plays an important role in the maintenance of cellular homeostasis. Dysregulation of autophagy is associated with several diseases. However, few studies have addressed the role of autophagy in the lung, and its role in lung diseases remains unclear. In the present study, we examined the effect of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) on autophagy in A549 cells and explored the underlying mechanisms...

MicroRNA (miR) can exert various biological functions by targeting oncogenes or tumor suppressor genes in numerous human malignancies. Recent evidence has shown that miR-148a increases the drug sensitivity of various cancer cells. Herein, we show that ectopic expression of miR-148a induces apoptosis, reduces clonogenicity, and increases the sensitivity to TRAIL and cisplatin in renal cancer cells. The luciferase reporter assay showed that miR-148a negatively regulated ras-related protein 14 (Rab14) expression by binding to the miR-148a binding site in the 3' untranslated region (3'UTR) of Rab14...

Multiple species of bats are reservoirs of rabies virus in the Americas and are occasionally the source of spillover infections into mesocarnivore species. Although rabies transmission generally is assumed to occur via bite, laboratory studies have demonstrated the potential for rabies transmission via ingestion of rabid animals. We investigated the ecological potential for this mode of transmission by assessing mesocarnivore scavenging behavior of dead bats in suburban habitats of Flagstaff, Arizona. In autumn 2013, summer 2014, and autumn 2015, we placed 104 rabies-negative bat carcasses either near buildings, in wildland areas, or in residential yards and then monitored them with trail cameras for 5 d...
