Vaziri et al. [1] propose a data-centric approach to synchronization. The key underlying concept of their work is the atomic set, which specifies the existence of an invariant that holds on a set of fields of an object type. In addition, they formalize a set of eleven data-access scenarios that completely specify the set of non-serializable interleaving patterns that can lead to an atomic-set s...

Cell senescence, originally defined as the proliferative arrest that occurs in normal cells after a limited number of cell divisions, is now more broadly regarded as a general biological program of terminal growth arrest. Replicative senescence of cells due to telomeric changes exhibits similar features with those seen in DNA damage (Vaziri et al., 1997; von Zglinicki, 2001). Therefore, DNA dam...

introduction in the east and northeast of sanandaj in the qorveh-bijar-takab axis, there are series of basaltic composition volcanoes with quaternary age. the study area is part of the sanandaj-sirjan zone and is located between 47°52' and 47°57' e longitudes and 35°26 and '35°30' n latitudes. due to the location of the volcanic cone on pliocene clastic sediments and quaternary travertine, the ...

in order to find the most effective concentration of 6-banzilamino purine (bap) and cycocel (ccc) on microtuber production of two potato cultivars under tissue culture conditions, a factorial experiment was carried out with randomized compelete design with 4 replications. four levels of bap (0, 5, 10 and 15 mg l-1) and four levels of ccc (0, 250, 500 and 1000 mg l-1) were applied on two potato ...

The recruitment of the error-prone Y-Family Translesion Synthesis (TLS) DNA polymerases (Pol , Pol , Pol , and REV1) to damaged chromatin is partly dependent on their association with Lysine 164 (K164)mono-ubiquitylated PCNA. RAD18 is the major PCNA K164-directed E3 ubiquitin ligase in eukaryotic cells and therefore plays potentially important roles in TLS and mutagenesis. Accordingly, there is...

he purpose of the article is to exhibit this fact that embellishments, despite of their lexical meaning, do not play just an ornamental role in iranian classical music, but they have an extremely important function to form the structural facets of dastgahi music; in fact, the embellishments are irremovable elements in the mentioned musical system. first of all, some brief explanations about con...

The intracellular metabolism of many carcinogenic polycyclic aryl hydrocarbons (PAHs, typified by the ubiquitous pollutant benzo[a]pyrene or B[a]P) generates electrophilic products that react covalently with genomic DNA. Cells that acquire PAH-induced DNA damage undergo growth arrest in a p53-independent manner (Vaziri, C., and Faller, D. V. (1997) J. Biol. Chem. 272, 2762-2769). In this report...

Cardiovascular disease is the major cause of death in patients with chronic kidney disease (CKD). Cardiovascular disease and many other complications of CKD are mediated by oxidative stress, inflammation, and dyslipidemia. This review provides a concise overview of the nature and mechanisms of CKD-induced lipid disorders and their adverse consequences. Lipid abnormalities in end-stage renal dis...
