In a comparison of the reverse passive haemagglutination test (RPHA) with the direct immunofluorescent and rapid carbohydrate utilisation tests for the identification of Neisseria gonorrhoeae isolated from clinical specimens, 315 isolates of oxidase-positive Gram-negative diplococci were tested as pure 24-hour-old subcultures and samples from 108 similar organisms were taken directly from prima...

biological monitoring using benthic organisms is one of the best and the most inexpensive methods for anthropogenic activities evaluation in aquatic ecosystems. the purpose of present investigation was biological monitoring of shahrud river that was performed in the qazvin province using by macro benthic invertebrates population. in the present investigation macro benthic invertebrate samples w...

Efforts to detect targets of recent positive selection (“selective sweeps”) in the genome frequently involve an initial screen of a region of the genome at a low density of markers (either SNPs or microsatellites), followed by a denser screen in the region flanking markers that show reduced or skewed variation relative to that predicted by an equilibrium neutral model or relative to “background...

background: compressive neuropathy of median nerve is relatively common but development of an hourglass like constriction is a rare phenomenon. the purpose of this study is to show morphologic changes of median nerve in advances carpal tunnel syndrome. methods: eighty patients with thenar atrophy, anesthesia and paresthesia of first, second and third finger and severe changes of emg‑ncv were ch...

1. The presence of 0.25 M NaCl during the reaction between a staphylococcus phage and susceptible organisms results in a five to tenfold increase in the amount of phage produced. 2. Analysis of the reaction indicates that normal kinetic relationships exist until just before lysis occurs. At this time the organisms enter the stationary phase, lysis is delayed approximately 0.7 hour as compared w...

The daily transition from light to darkness has significantly shaped the evolution of most living species, from unicellular organisms to mammals. Adaptation to this environmental constraint occurred through the emergence of a circadian system capable of adjusting both behavioral and physiological processes to this light-dark cycle. Superimposed upon the daily light-dark cycle is a seasonal infl...

Though nanomaterials have wide applications in various fields, they also have some toxic effects in them known as nanotoxic effects. This paper discusses about the various causes and effects of nanotoxicology in the field of medicine, in female (mice) reproductive system, on fetal organogenesis and morphology and toxicity of nanoparticles in zebrafish embryo.

Historically, forested riparian buffers have been created to provide protection for aquatic organisms and aquatic ecosystem functions. Increasingly, new and existing riparian buffers are being used also to meet terrestrial conservation requirements. To test the effectiveness of riparian buffers for conserving terrestrial fauna, we conducted a meta-analysis using published data from 397 comparis...
