humans suffer transient or persistent starvation due to a lack of food intake, either because of fasting, voluntary dieting, or due to the scarcity of available food. at the cellular level it is possible to possess pathological starvation during ischemia and solid tumors. blood provides many nutrients to our cells, and researchers provide these nutrients to cells in culture in the form of enric...

the main goal of the present study was to implement a hybrid pattern of cellular automata model and particle swarm optimization algorithm based on tm and etm+ imagery of landsat satellite from 1988 to 2010 for simulating the urban sprawling. in this study, an alternative model was implemented in two ways: the first method was based on two images (1988 and 2010) and the second one was based on t...

The present study was designed to investigate the anti-melanogenic and cytotoxic activities of methanol extract of Phlomis kurdica. The antioxidant and anti-tyrosinase activity of MeOH extract from P. kurdica (MPk) were examined by DPPH radical scavenging and mushroom tyrosinase activity assays (in vitro), respectively. Furthermore, the effect of MPk on the melanin content, cellular tyrosinase ...

background: none-chemical distant cellular interactions (ncdci) are among the unexplained issues in cell biology. one example of such interactions is the biophoton-induced growth. in this process, photon emissions from one cell can induce mitosis in other cells while they are chemically separated. this effect is evident among many species. hypothesis: it is hypothesized that some simple but uni...

future increase of mobile communication subscribers will require a great capacity expansion of the cellular systems. in order to accommodate the increasing number of subscribers, the cell size will have to be much smaller than current size. therefore, it is predictable that the location updating and paging procedures will produce a major part of signaling traffic in these networks. this pape...

SUMMARY The aging process occurs due to the decline of vital physiological functions and adaptability body, being influenced by genetics lifestyle. With advances in genetics, biological can be calculated telomere length. Telomeres are regions at ends chromosomes that play a role maintenance integrity DNA. aging, shortening occurs, causing cellular senescence. Several studies show shorter telome...
