Kinesin-3 KIF1A (UNC-104 in C. elegans) is the major axonal transporter of synaptic vesicles and mutations in this molecular motor are linked to KIF1A-associated neurological disorders (KAND), encompassing Charcot-Marie-Tooth disease, amyotrophic lateral sclerosis and hereditary spastic paraplegia. UNC-104 binds to lipid bilayers of synaptic vesicles via its C-terminal PH (pleckstrin homology) domain.

Executive function involves the efficient and adaptive engagement of the control processes of updating, shifting, and inhibition (Miyake, 2000) to guide behavior toward a goal. It is associated with decrements in many other cognitive functions due to aging (West, 1996; Raz, 2000) with itself particularly vulnerable to the effect of aging (Treitz et al., 2007).

The present study was to investigate (1) whether LPS application increased goblet cell secretion by compound exocytotic activity in mucosal villi and crypts of rat small intestine, and (2) whether hydroxyl radicals were involved in LPS-induced compound exocytosis in goblet cells and plasma leakage. Scanning electron microscopy showed that the numbers of goblet cells undergoing compound exocytosis (cavitated goblet cells) per mm(2) of ileal villus epithelium in rats 5 and 30 min after LPS (15 mg kg(-1)) were 693 +/- 196 (N = 6) and 547 +/- 213 (N = 6), respectively, which were 5.

Aim Of The Study: Antrodia camphorata, a precious folkloric medicinal mushroom, has been used to treat tumorigenic diseases in Taiwan. This study was to investigate the innate immunity augmentation effects of different fractions prepared from hot water extracts of submerged cultured Antrodia camphorata (AC).
Materials And Methods: The cytokine induction potency of AC fraction in diluted peripheral blood culture was measured by ELISA.
Cordyceps sinensis is widely used as a traditional medicine for treatment of a wide variety of diseases or to maintain health. The immunomodulatory activity of polysaccharides prepared from submerged cultured C. sinensis BCRC36421 was investigated in human peripheral blood.

The nutritional medium requirement for biomass and triterpenoid production by Antrodia cinnamomea AC0623 strain was optimized. Box-Behnken was applied to optimize biomass and triterpenoid production. According to response surface methodology (RSM), the optimum concentrations of N-source were determined.
