background: haemonchosis has a negative effect on the farming industry throughout the world, especially in the tropic and sub-tropic countries. the present study was carried out to differentiate haemonchus species from its main hosts in iran, including sheep, goat and camel.   methods: the identification took place based on the morphometrics of the spic-ules and molecular characters. two hundre...

The M-transcript of human choline acetyltransferase (ChAT) produces an 82-kDa protein (82-kDa ChAT) that concentrates in nuclei of cholinergic neurons. We assessed the effects of acute exposure to oligomeric amyloid-β1-42 (Aβ1-42) on 82-kDa ChAT disposition in SH-SY5Y neural cells, finding that acute exposure to Aβ1-42 results in increased association of 82-kDa ChAT with chromatin and formation...

Heat shock protein/Thermotolerance/Cycloheximide The relation of heat shock protein (HSP) synthesis and development of thermotolerance was compared in Chinese hamster V79 cells of low, and mouse L cells of high, thermosensitivities. Thermotolerance was induced by step-up heating (42•Ž, 2 hr and 44•Ž). Cycloheximide did not inhibit the development of ther motolerance in V79 cells. In contrast, n...

In this study, the effects of four different temperatures on sporulation and development 6 Bacillus species, 2 native 4 reference were investigated. The SDS PAGE analysis emerged that two proteins, 40 39 kilodalton (kDa), produced by sphaericus ATCC 2362 after 24 48, respectively hours at 48°C, local isolate 48 42°C 31 48°C. Additionally firmus (ATCC 14573) a kDa protein 52°C thuringiensis var....

Ligand-induced regulation of the rat kappa-opioid receptor (rKOR) was investigated in human embryonic kidney 293 cells stably expressing the FLAG-tagged rKOR. Incubation of rKOR cells with naltrexone for 24 h increased the B(max) >3-fold, with no change in the affinity of [(3)H]diprenorphine. Two immunoreactive receptor species were present in cell lysates: naltrexone treatment caused a >3-fold...

The agent of human granulocytic ehrlichiosis (HGE), Ehrlichia phagocytophila, and Ehrlichia equi are very similar. HGE is of variable severity. Genetic and antigenic differences among 3 human isolates (Webster, Spooner, and NY-8) and 1 horse isolate (MRK) were evaluated. The 16S rRNA gene sequences were identical in all human isolates. By use of 5 homologous antisera from these 3 humans and 1 h...
