BACKGROUND: Intestinal mucositis is a most frequently occurring toxicity in cancer chemotherapy, and consequent malnutrition reduces tolerance to cancer therapies. Therefore it is important to lessen the severity of mucotitis and to develop complementary agents capable of reducing mucotitis-related symptoms. This study was conducted to determine 5-fluorouracil (5-FU) induced intestinal damage to understand intestinal damages due to chemotherapy and to provide information on biomarkers which can

We aimed to elucidate whether the eNOS T-786C mutant allele is implicated in subarachnoid hemorrhage (SAH) susceptibility or vasospasm after SAH, and whether the mutant allele is differentially expressed in those with small and large ruptured aneurysms in Korean population. 136 consecutive patients diagnosed with aneurismal SAH and 113 controls were recruited. Polymerase chain reaction and direct sequencing of both strands were performed to determine genotypes with respect to the eNOS T-786C mut

Cell cycle variations in the phosphorylation of chromatin-associated nonhistones were determined. Cells were radiolabeled with [32P]orthophosphate and chromatin was obtained by mild digestion of nuclei with micrococcal nuclease. The experiments were performed in the presence of a substrate inhibitor of alkaline phosphatase, beta-glycerophosphate. The results show that, while similar molecular weight species of phosphorylated nonhistones are associated with interphase chromatin through the HeLa c

A novel approach to utilizing whey permeate, the cultivation of mycelia of the edible mushroom Ganoderma lucidum, is introduced. The major objective of this research was to use whey permeate as an alternative growth medium for the cultivation of mycelia of edible mushroom G. lucidum and to find an optimum condition for solid-state cultivation. Response surface analysis was applied to determine the combination of substrate concentration (25 to 45 g of lactose/L), pH (3.5 to 5.5), and temperature

While harmful effects of blue light on skin cells have been recently reported, there are few studies regarding natural products that alleviate its negative effects. Therefore, we investigated ameliorating effects of yellow chaste weed (YCW) (Helichrysum arenarium) extract and its components, apigenin and galangin, on blue light-irradiated HaCaT cells. In this study, we found that YCW extract improved the reduced proliferation of HaCaT cells induced by blue light-irradiation and reduced blue ligh

Olfactory receptors (ORs), which belong to the G-protein-coupled receptor family, have been widely studied as ectopically expressed receptors in various human tissues, including the skin. However, the physiological functions of only a few OR types have been elucidated in skin cells. All-trans retinoic acid (ATRA) is a well-known medication for various skin diseases. However, many studies have shown that ATRA can have adverse effects, resulting from the suppression of cell proliferation. Here, we
