the imbalance between pro-oxidants and anti-oxidants leads to generation of oxygen/nitrogen free radicals which are implicated in several neurodegenerative diseases. fagonia arabica is an ethno-pharmacologically important ayurvedic herb known to have many medicinal properties like anti-inflammatory, analgesic and antipyretic effects. however, its antioxidant potential has not been investigated ...

objective: hydrostatic pressure is crucial component of cell environment and fundamental physical quantity, also it is the main factor of both cell integrity and function. pressure variation disorder, beyond physiological limits, may lead to pathological states. in this study, we examined the effect of hydrostatic pressure on apoptosis induction, viability, morphology, adhesion potency to subst...

Objective(s): Impairment of nerve cells of brain induced by hypoxia results in energy-deprivation and dysfunction, which accompanies with neurons apoptosis. Improving function of nerve cells is important for treating cerebral anoxia. This study aimed to investigate the role of Quercetin (Quer) in hypoxia-induced injury of pheochromocytoma (PC-12) cells. Materials and Methods: PC-12 cells were c...

introduction: bombesin is a 14-aminoacid peptide isolated from frog skin. the mammalian counterparts of the frog peptide are neuromedin b (nmb) and gastrin-releasing peptide (grp). bombesin (bbn) is a peptide showing high affinity for the gastrin releasing peptide receptor (grpr). prostate, small cell lung cancer, breast, gastric, and colon cancers are known to over express receptors to bombesi...

Olfactory ensheathing cells (OEC) have been successfully used to stimulate the growth of injured fibers and to promote functional recovery within the injured adult CNS. These cells exhibit functional properties, which are known to be involved in axonal elongation. OEC express high level of growth factors including NGF, GDNF, BDNF and NT-3, which are known to play an important role in nerve rege...

Nerve growth factor (NGF) is known to increase the levels of neurofilament proteins in PC-12 pheochromocytoma cells. In this report, we show that the three neurofilament subunits, NF-L, NF-M, and NF-H, are not induced coordinately. NF-H accumulated only after longer term NGF treatment than required for NF-L and NF-M. While NGF treatment resulted in 12- and 14-fold increases in NF-L and NF-M mRN...
