Tabanids are among the most free-living adult flies which play a role as livestock pests. A single blood meal is used as a source of energy for egg production (100-1,000 eggs per meal), and females of certain species can oviposit before a blood meal is obtained (autogeny). Therefore, the maintenance of annual populations requires successful oviposition by only 2% of females. Wild animal blood s...

About 12,000 chemical compounds isolated from medicinal plants and used to conduct crucial biological functions. These phytochemicals offer long-term health benefits for humans, thus they can be effectively treat a variety of human ailments. The goal this study was assess the in vitro free radical scavenging antibacterial activities glycoside, flavonoid alkaloid extracts Tilia cordata plant. Ac...

A small set of nojirimycin- and pyrrolidine-based iminosugar derivatives has been synthesized and evaluated as potential inhibitors of porcine and insect trehalases. Compounds 12, 13 and 20 proved to be active against both insect and porcine trehalases with selectivity towards the insect glycosidase, while compounds 10, 14 and 16 behaved as inhibitors only of insect trehalase. Despite the fact ...

Drosophila simulans is known to harbor three distinct mitochondrial DNA (mtDNA) haplotype groups (siI, -II, and -III) with nearly 3.0% interhaplotypic divergence but <0.06% intrahaplotypic diversity. With the large amount of genetic variation in this system, the potential power to detect intraspecific fitness differences in fly lines that carry distinct haplotypes is great. We test three life-h...

Protein cleavage is a common feature in human neurodegenerative disease. Ataxin-3 protein with an expanded polyglutamine (polyQ) repeat causes spinocerebellar ataxia type-3 (SCA3), also called Machado-Joseph disease, and is cleaved in mammalian cells, transgenic mice and SCA3 patient brain tissue. However, the pathological significance of Ataxin-3 cleavage has not been carefully examined. To ga...
