Antimicrobial peptides are crucial components of the innate host defense system of most living organisms and promising candidates for antimicrobial agents. Accurate classification of antimicrobial peptides will be helpful to the discovery of new therapeutic targets. In this work, the Increment of Diversity with Quadratic Discriminant analysis (IDQD) was presented to classify antifungal and antibacterial peptides based on primary sequence information. In the jackknife test, the proposed IDQD model yields an accuracy of 86...

Controversy exists as to whether African American (AA) transplant recipients are at risk for developing de novo donor-specific anti-human leukocyte antigen (HLA) antibody (dnDSA). We studied 341 HLA-mismatched, primary renal allograft recipients who were consecutively transplanted between 3/1999 and 12/2010. Sera were collected sequentially pre- and post-transplant and tested for anti-HLA immunoglobulin G (IgG) via single antigen bead assay. Of the 341 transplant patients (225 AA and 116 non-AA), 107 developed dnDSA at a median of 9...

1)Determining the factors governing investment in immunity is critical for understanding host-pathogen ecological and evolutionary dynamics. Studies often consider disease resistance in the context of life-history theory, with the expectation that investment in immunity will be optimized in anticipation of disease risk. Immunity, however, is constrained by context-dependent fitness costs. How the costs of immunity vary across life-history strategies has yet to be considered. 2)Pea aphids are typically unwinged but produce winged offspring in response to high population densities and deteriorating conditions...

Increased frequency and length of high heat episodes are leading to more cardiovascular issues and asthmatic responses among the population of San Juan, the capital of the island of Puerto Rico, USA. An urban heat island effect, which leads to foci of higher temperatures in some urban areas, can raise heat-related mortality. The objective of this research is to map the risk of high temperature in particular locations by creating heat maps of the city of San Juan. The heat vulnerability index (HVI) maps were developed using images collected by satellite-based remote sensing combined with census data...

INTRODUCTION: For late-life neurocognitive disorders, as for other late-life chronic diseases, much recent interest has focused on the possible relevance of Developmental Origins of Health and Disease (DOHaD). Programming by undernutrition in utero, followed by overnutrition in adult life may lead to an increased risk, possibly mediated through cardiovascular and metabolic pathways. This study will specifically examine, if lower birth weight is associated with poorer cognitive functioning in late life in a south Indian population...

INTRODUCTION: USA Football has made the Heads Up Football (HUF) concussion education program available for coaches of youth football players. Existing evidence about the effectiveness of the HUF coach education program is equivocal. For HUF and other programs, there is growing concern that even effective interventions can increase inequalities if there is different uptake or impact by SES or other demographic factors. Understanding how adoption is patterned along these lines is important for understanding equity issues in youth football...

One of the great challenges in cellular studies is to develop a rapid and biocompatible analytical tool for single-cell analysis. We report a rapid, DNA nanostructure-supported aptamer pull-down (DNaPull) assay under convective flux in a glass capillary for analyzing contents of droplets with nano or picoliter volumes. We have demonstrated that the scaffolded aptamer can greatly improve the efficiency of target molecules' pull-down. The convective flux enables complete reaction in less than 5 min, which is an 18-fold improvement compared to purely diffusive flux (traditional model of stationary case)...

This study addresses the viability of the lichen Xanthoria elegans after high-dose ionizing irradiation in the frame of the STARLIFE campaign. The first set of experiments was intended to resemble several types of galactic cosmic radiation (GCR) as present beyond the magnetic shield of Earth. In the second set of experiments, γ radiation up to 113 kGy was applied to test the limit of lichen resistance to ionizing radiation. Entire thalli of Xanthoria elegans were irradiated in the anhydrobiotic state. After STARLIFE 1, the metabolic activity of both symbionts was quantified by live/dead staining with confocal laser scanning microscopy...

Diabetes Mellitus (DM) is a chronic disorder caused by relative or absolute insulin deficiency and characterized by chronic hyperglycaemia. It is expected that by year 2025, 80% of all Type 2 Diabetic patients will be living in developing or low and middle income countries. Among Asians, there has been an overall increase in abdominal obesity however, the risk of diabetes in these populations starts at much lower body mass index (BMI) as compared to Caucasians. A significant proportion of diabetic patients with adult-onset, initially non-requiring insulin treatment, depicts diabetes-associated autoantibodies in their sera...

Alzheimer's disease (AD) represents one major health concern for our growing elderly population. It accounts for increasing impairment of cognitive capacity followed by loss of executive function in late stage. AD pathogenesis is multifaceted and difficult to pinpoint, and understanding AD etiology will be critical to effectively diagnose and treat the disease. An interesting hypothesis concerning AD development postulates a cause-effect relationship between accumulation of mitochondrial DNA (mtDNA) mutations and neurodegenerative changes associated with this pathology...
