Methylmercury (MeHg) is a pervasive and ubiquitous environmental neurotoxicant within aquatic ecosystems, known to alter behavior in fish and other vertebrates. This study sought to assess the behavioral effects of developmental MeHg exposure on larval yellow perch (Perca flavescens)-a nonmodel fish species native to the Great Lakes. Embryos were exposed to MeHg (0, 30, 100, 300, and 1000 nM) f...

BACKGROUND Bisphenol A (BPA), used in the manufacture of plastics, is ubiquitously distributed in the aquatic environment. However, the effect of maternal transfer of these xenobiotics on embryonic development and growth is poorly understood in fish. We tested the hypothesis that BPA in eggs, mimicking maternal transfer, impact development, growth and stress performance in juveniles of rainbow ...

To evaluate whether simultaneous metallic stent (MS) placement and radiotherapy are feasible, phantom and animal experiments were performed. The interface dose by external irradiation (EI) or intracavity irradiation (II) to 5 kinds of MS was measured using the charge-coupled device (CCD) camera with a thermoluminescent (TL) sheet, and backscatter and absorption were evaluated using composite me...

Aim: The present study was designed to evaluate the toxic interaction of fumonisin B and ochratoxin A, alone and in 1 combination for pathology of the kidneys in day old Japanese quail. Materials and Methods: Day old Japanese quail chicks were divided into 4 groups and fed with basal quail chick mash containing fumonisin B @ 200 ppm (Group FX), Ochratoxin A @ 2 ppm (Group OX), and fumonisin B @...

Expression of different ion channels permits homologously-generated neurons to acquire different types of excitability and thus code various kinds of input information. Mauthner (M) series neurons in the teleost hindbrain consist of M cells and their morphological homologs, which are repeated in adjacent segments and share auditory inputs. When excited, M cells generate a single spike at the on...

In distributed target tracking in wireless sensor networks (WSN), agreement on the target state is usually achieved by the construction and maintenance of a communication path. Such an approach lack robustness to failures, and is not applicable to asynchronous networks. Recently, methods have been proposed that can solve these problems using consensus algorithms. However, these methods suffer f...

Abstract Diesel particulate filters is the most effective post-treatment device used to reduce diesel exhaust emissions. As amount of matter captured in filter continues increase, pressure engine gradually increases, thereby affecting power performance engine. Therefore, when capture reaches a certain value, needs be regenerated. Regeneration will produce secondary pollution, which CO one impor...

Sustainable forest management is the key to biodiversity conservation, flow of resources and climate change mitigation. We assessed impact various regimes (FMRs): legal felling series [(reserve (RF), demarcated protected (DPF), un-demarcated (UPF), co-operative society (CSF) un-classed (UF)] on conservations carbon storage in Acacia catechu Willd. Dominated northern tropical dry deciduous ecosy...

Zebrafish (Danio rerio) are becoming one of the most important model organisms in behavioural neuroscience. It has been shown repeatedly that different zebrafish strains show large differences. These divergent profiles may have a genetic basis, but environmental factors and previous experience also known to greatly affect phenotype zebrafish. could be expected differences at larval stage should...

Currently, natural fibers attract the attention of researchers and builders in construction industry as they are eco-friendly, cost-effective, lightweight, renewable resources. The inclusion concrete mortar will contribute to solving environmental problems associated with dumping or burning them improve properties durability mortar. Similar other fibers, Date Palm Fibers (DPF) have been receivi...
