Complex molecular mechanisms control B-cell fate to become a memory or a plasma cell. Interleukin-24 (IL-24) is a class II family cytokine of poorly understood immune function that regulates the cell cycle. We previously observed that IL-24 is strongly expressed in leukemic memory-type B cells. Here we show that IL-24 is also expressed in human follicular B cells; it is more abundant in CD27(+)...

objective: thymoquinone (tq), as the main component of nigella sativa plant, shows anticancer properties. this study was aimed to evaluate the combined effect of tq and tamoxifen (tam) on viability and apoptosis of human breast cancer cell lines. materials and methods: in this experimental study, estrogen positive mcf-7 and estrogen negative mda-mb-231 human breast cancer cell lines were induce...

The administration of 28-O-propynoylbetulin at a concentration equal to or less than 1 μg/ml did not cause a statistically significant change in the cell proliferation in either melanoma cell line (compared to control, p>0.05). Higher concentrations of the compound (3 and 10 μg/ml) inhibited the cell growth (in comparison to control, p<0.05). These results corresponded with caspase-3 activity r...

active video gaming and other energy-balance related behaviours in adolescents: a 24-hour recall diary study. Abstract Background

We propose a string realization of the AdS4 brane in AdS5 that is known to localize gravity. Our theory is M D5 branes in the near horizon geometry of N D3 branes, where M and N are appropriately tuned.
