objective the hippocampal circuit integrity is crucial for learning and memory. despite the existing reports on hippocampal–dependent memory impairment due to noise stress, there are only a few studies on the effect of noise stress on anatomical structure of hippocampus. the present study is aimed to investigate the likely effects of chronic noise exposure on the volume of rat hippocampus. mate...

Volume visualization is a method of extracting meaningful information from volumetric data using interactive graphics and imaging. It is concerned with volume data representation, modeling, manipulation, and rendering [36][137][138][227]. Volume data are 3D (possibly time-varying) entities that may have information inside them, might not consist of tangible surfaces and edges, or might be too v...

background: in the field of mammalian embryo culture, the putative influence of autocrine/ paracrine factor(s), produce by the embryos itself, is under investigation. a smaller medium drop can prevent dilution of this factor(s). objective: the objective of this study was to examine the effect of culture medium volume on in vitro development of mouse 2-cell embryos. materials and methods: the em...

background: radon and its daughter product are a major source of natural radiation exposure, the measurement of radon concentration in dwellings is assuming ever increasing importance. it is known from recent surveys in many countries that radon and its progeny contributes significantly to total inhalation dose and is well established that radon when inhaled in large quantity causes lung disord...

in recent years, biosurfactants due to wide applications in chemical, petroleum, food andpharmaceutical industries, have been widely considered by researchers. biosurfactants are produced by aseries of microorganisms, so it is important to screen culture medium and operating conditions in miniaturized bioreactors prior to scaling up to large bioreactors.in this study, using a kind of miniaturiz...
