This study focuses on optimization and validation of an Ultrahigh-performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) method for simultaneous analysis of 11mycotoxins: Aflatoxin B1, T-2 Toxin, Ochratoxin A, Deoxynivalenol and Zearalenone in wheat matrix. Sample extraction and cleanup procedure is based on a single extraction step using acetonitrile/water/acetic acid mixture...

Today, agrigenomics researchers have a wide variety of technologies at their disposal for collecting genetic information. Array-based approaches to SNP screening have been the method of choice in analyzing and associating traits with regions of the genome for many plants and animals. As sequencing costs continue to decline, new approaches that leverage next-generation sequencing (NGS) technolog...

BACKGROUND AND PURPOSE DW-MRS is a promising tool for the noninvasive identification of the cellular response to cerebral ischemia. To date, the potential confounding effects of aging and the stage of ischemia are unknown. We, therefore, examined the cross-sectional effects of age and different stages of cerebral ischemia on the diffusion of brain metabolites. MATERIALS AND METHODS The ADCs o...

PURPOSE To retrospectively determine the accuracy of diffusion-weighted (DW) magnetic resonance (MR) imaging for identifying cancer in the prostate peripheral zone (PZ) and to assess the accuracy of tumor volume measurements made with T2-weighted imaging and combined T2-weighted and DW MR imaging by using surgical pathologic examination as the reference standard. MATERIALS AND METHODS The ins...

In 2007, the Ontario Ministry of Health and Long-Term Care made an investment to support full-time employment for new graduate nurses. This paper describes the collaboration of policy makers and researchers in the creation and implementation of the Nursing Graduate Guarantee (NGG). We provide historical context for the development of the initiative and discuss some of the issues related to its ...

anzali wetland is one of the most important aquatic ecosystems of iran located in south of the caspian sea. this wetland is a habitat for valuable fishes and aquatic animals which have an important role in life cycle of this ecosystem. agroup of the pollutants entering these wetlands is the persistent organic pollutants. this pollutants has a wide range of ingredients in the environment and are...

BACKGROUND AND PURPOSE Obstructive sleep apnea (OSA) subjects show brain injury in sites that control autonomic, cognitive, and mood functions that are deficient in the condition. The processes contributing to injury may include altered blood-brain barrier (BBB) actions. Our aim was to examine BBB function, based on diffusion-weighted pseudo-continuous arterial spin labeling (DW-pCASL) procedur...

Despite the established importance of rodents as reservoirs of vector-borne zoonoses in East Africa, there is relatively limited information regarding the infestation parameters and host associations of ectoparasites that vector many such pathogens among small mammals in this region. Between 2009 and 2013, small mammals were livetrapped in the semiarid savanna of Kenya. A subset of these indivi...
