INTRODUCTION The work of Kennedy (1940) showed that flying mosquitoes (Aedes aegypti) orientate themselves inaccurately but consistently away from the source of a horizontal beam of artificial light and also that when presented with several moving black stripes they tend to face one orother of them. This characteristic negative phototaxis of mosquitoes during daytime has either been observed or...

pure submandibular saliva was collected from anaesthetized vitamin - a - treated and control rats with using of pilocarpine as secretogogue, and then the serum was collected by cardiac puncutre. intraperitoneal injection of a large single dose (100,000 iu/kg) of vitamin a changed total protein, calcium and sodium concentrations of saliva so that sodium level of submandibular saliva was reduced ...

Background: Protein intake has been associated with the development of pre-diabetes (pre-T2D) and type 2 diabetes (T2D). The gut microbiota capacity to produce harmful metabolites derived from dietary protein. Furthermore, both composition metabolic status (e.g., insulin resistance) can be modulated by diet ethnicity. However, date most studies have predominantly focused on carbohydrate fiber r...

Single-laboratory studies conducted under highly standardized conditions are the gold standard in preclinical animal research. Using simulations based on 440 preclinical studies across 13 different interventions in animal models of stroke, myocardial infarction, and breast cancer, we compared the accuracy of effect size estimates between single-laboratory and multi-laboratory study designs. Sin...

An RNA fraction with messenger activity has been isolated from free polysomes of rabbit liver. This liver RNA was translated in a reticulocyte cell-free system, which had been rendered dependent on exogenous messenger RNA by mild ribonuclease treatment. After ribonuclease was removed from the ribosomes, protein synthesis was almost totally dependent on 0.5 M KC1 ribosomal wash protein and exoge...

The bovine spongiform encephalopathy (BSE) epidemic in 1986 highlighted the importance of rendering industry as a key component food supply chain. Prior to was poorly understood. However, following emergence BSE research commissioned characterise systems and investigate their ability inactivate transmissible (TSE) agents. Six were found be operational Europe but process parameters, such particl...
