OBJECTIVE Fluid shear stress (flow) modulates endothelial cell (EC) function via specific signal transduction events. Previously, we showed that flow-mediated tyrosine phosphorylation of p130 Crk-associated substrate (Cas) required calcium-dependent c-Src activation. Because flow increases reactive oxygen species (ROS) production in ECs and because H(2)O(2) increases tyrosine phosphorylation of...

The genotoxic and antigenotoxic effects of Aloe vera leaf extract (AV) were investigated using the chromosome aberrations (CAs) test for the bone marrow cells of rats, sister chromatid exchanges (SCEs) and micronucleus (MN) and CAs tests for human lymphocytes, and the Ames Salmonella/microsome test system. In the bone marrow cells of rats, AV extract significantly induced structural and total C...

We introduce a new shared memory object: the write-and-f-array, provide its wait-free implementation and use it to construct an improved wait-free implementation of the fetch-and-add object. The write-and-f-array generalizes single-writer write-and-snapshot[5] object in a similar way that the f-array[7] generalizes the multi-writer snapshot object. More specifically, a write-and-f-array is para...

effect of controlled atmospheres (cas) at various concentrations of co2, n2 and o2 on the lethal times of tribolium castaneum and trogoderma granarium was investigated at 20 and 30 ºc. experiments were performed using a recirculatory multi-flask apparatus. the results revealed that, the shortest times (0.1, 0.3 and 0.9 day for adults, larvae and pupae, respectively) required to obtain 50% morta...

Ti3SiC2/Al2O3 composites have attracted attention due to their excellent mechanical and electromagnetic properties, but the high temperatures (≥ 1400 ℃) required for densification of aluminum oxide (Al2O3) leads decomposition Ti3SiC2. To address this issue, Ti3(SixAl1−x</...

This paper proposes an efficient method to analyze the worst case interruption delay (WCID) of a workload running on modern microprocessors using a cycle accurate simulator (CAS). Our method is highly accurate because it simulates all possible cases inserting an interruption just before the retirement of every instruction executed in a workload. It is also (reasonably) efficient because it take...
