Tupling, R., H. Green, S. Grant, M. Burnett, and D. Ranney. Postcontractile force depression in humans is associated with an impairment in SR Ca21 pump function. Am. J. Physiol. Regulatory Integrative Comp. Physiol. 278: R87– R94, 2000.—To investigate the hypothesis that intrinsic changes in sarcoplasmic reticulum (SR) Ca21-sequestration function can be implicated in postcontractile depression ...

the genus rhodococcus is gram positive bacterium which was classified into the family of nocardiaceae. the organism can be isolates from different sources, with capability to degrade diverse types of pollutant. nowadays, scientists reported a few secondary metabolites which are produced by rhodococci. hence, the present study tried to isolate rhodococci from different soil samples with the capa...

Previous examination of the accessibility of a panel of single-Cys mutants in transmembrane domain III (TMDIII) of the yeast mitochondrial citrate transport protein to the hydrophilic, cysteine-specific methanethiosulfonate reagent MTSES enabled identification of the water-accessible surface of this TMD. Further studies on the effect of citrate on MTS reagent accessibility, indicated eight site...

Bacteriophage λ provided one of the early paradigms for studying gene control and understanding how molecular switches work [1]. After infection by bacteriophage λ, two possible fates, reflecting alternative patterns of gene expression, await the bacterial host cell. Either the bacteriophage enters the lytic pathway, in which case the host cell ultimately lyses to release a burst of progeny pha...

THE WORD “homeostasis” comes from Greek μοιος, hómoios meaning “similar” and στάσις, stasis meaning “standing still” (7). The concept of homeostasis is associated with living organisms and their ability to maintain a stable, internal environment. This concept originated from Claude Bernard and his discussions of milieu interieur during his career in the mid-tolate 1800s. Claude Bernard relied o...

Making use of deficiencies, inversions and translocations, we have genetically dissected the region 95E to 96F of Drosophila melanogaster. We localized cytologically the loci abnormal spindle (asp: 385.2: 96A20-25;96B1-10) and M(3)96C2 (96C1;96C5). We have also found several new phenotypes associated with lesions in the 95E to 97B region: (1) Minute(3)96A (M(3)96A) is a haplo-insufficient pheno...
