Under some relaxed conditions, in this paper we obtain some equivalent conditions on the asymptotics of the density of the supremum of a random walk with heavy-tailed increments. To do this, we investigate the asymptotics of the first ascending ladder height of a randomwalk with heavy-tailed increments. The results obtained improve and extend the corresponding classical results.
Mitochondrial membrane permeability transition (MPT) plays a crucial role in apoptotic tail shortening during anuran metamorphosis. L-carnitine is known to shuttle free fatty acids (FFAs) from the cytosol into mitochondria matrix for β-oxidation and energy production, and in a previous study we found that treatment with L-carnitine suppresses 3, 3', 5-triiodothyronine (T3 ) and FFA-induced MPT ...
We have examined the behavior of T7 RNA polymerase (RNAP) at a set of promoter variants having all possible single base pair (bp) substitutions. The polymerase exhibits an absolute requirement for initiation with a purine and a strong preference for initiation with GTP vs ATP. Promoter variants that would require initiation at the normal start site (+1) with CTP or UTP result in a shift in init...
OBJECTIVE To study whether Lycium barbarum glycopeptide 3 (LBGP3) affects T cell apoptosis in aged mice. METHODS LBGP3 was purified with DEAE cellulose and Sephadex columns. Apoptotic "sub-G1 peak" was detected by flow cytometry and DNA ladder was resolved by agarose gel electrophoresis. Levels of IFN-gamma and IL-10 were measured with specific kits and mRNA expression was detected by RT-PCR....
We revealed the cytotoxic effect of the flavonoid, fisetin (FIS), on human COLO205 colon cancer cells in the presence and absence of the HSP90 inhibitors, geldanamycin (GA) and radicicol (RAD). Compared to FIS treatment alone of COLO205 cells, GA and RAD significantly enhanced FIS-induced cytotoxicity, increased expression of cleaved caspase-3 and the PAPR protein, and produced a greater densit...
Injuries from slips, falls and overexertion during ladder cfimbing activities are common in both occupational and non-occupational environments. Little is known, however, about the task, equipment, and user parameters which may cause these injuries. In order to evaluate the hazards assocmted with ladder climbing, ten male subjects were tested under combinations of ladder rung separation, ladder...
for many years, meaning of work was to meet needs, physical and financial resources for human. in this times, work was consists of samples activities and easy to learn. so people do routine work duties for lifetime. survived goals were major ressoon for work. with population grow and increasing diversity and complexity of work, progress and successfully paradigm was more comprehensive. in this ...
