conclusions expression levels of 1,426 genes were significantly up-regulated in the mutant compared to wt. furthermore, 301 genes were down-regulated with false discovery rates (fdr) of < 0.001 and absolute value of log2 ratio of ≥ 1. results a total of 4,182,944 and 4,182,021 clean tags were obtained from the wt and a nonpathogenic mutant stain (bct89), respectively, and 10,410 differentially ...

conclusions this study showed that the presence of mutation at codons rtl80v, rtl180m and rtm204v in a, b and c domains is associated with higher viral load and resistance to lamivudine (3tc) respectively. results about 6% (3 of 50) of samples were hbeag positive and 94% (47 of 50) of patients were hbeag negative by elisa method. the patients' alt level was between 16 and 95 iu/l with the mean ...

haemorrhagic septicaemia (hs) is a fatal systemic disease of cattle and buffaloes. some control isachieved with administration of alum-precipitated or oil-adjuvanted killed whole-cell vaccines injectedsubcutaneously. these vaccines, however, provide only short-term immunity and for effective use, theyshould be administered annually. we constructed an aroa attenuated derivative of a pasteurella ...

the structural requirements for the inhibitor activity of various furan carboxanilide derivatives against succinate dehydrogenase complex (sdc) activity in mitochondria of either wild or mutant strains of ustilago maydis were investigated with the aid of hansch qsar analysis. it has been found that the inhibitor activity against both types of enzymes is best related to the ??? or ??m of the sub...

There has been much debate as to whether muscle is present in normal lymph nodes and, if so, where. There are few records of muscle in abnormal lymph nodes. An incidental observation of muscular proliferation (Lott and Davies, this Journal, 1983, 98, 90-91) in an axillary node draining breast carcinoma prompted this further investigation. Examination by dissection microscopy and at higher magni...

Complex oligosaccharides from human milk (HMO) possess an antimicrobial activity and can promote the growth of bifidobacteria such as Bifidobacterium bifidum and Bifidobacterium longum subsp. infantis. In addition, fermentation of carbohydrates by bifidobacteria can result in the production of metabolites presenting an antivirulence effect on several pathogenic bacteria. Whey is rich in complex...

Nontyphoidal Salmonella species cause gastrointestinal disease worldwide. The prevailing theory of Salmonella enteropathogenesis is that bacterial invasion of the intestinal epithelium is essential for virulence and that this requires the virulence-associated genomic region Salmonella pathogenicity island 1 (SPI-1). Recent studies of Salmonella enterica infection models have demonstrated that e...
