introduction: astrocytes, the most abundant glia in the central nervous system, modulate neuronal survival and function. astrocytic functions are mediated by synthesis and secretion of wide ranges of polypeptides through mechanism (s) poorly understood. among these, tgfβs are synthesized and released by the astrocytes. in this study, the involvement of wnt signaling pathway on the synthesis of ...

Familial amyloid polyneuropathy (FAP) type IV (FINNISH) is a rare clinical entity with challenging neuropathy and cosmetic deficits. Amyloidosis can affect peripheral sensory, motor, or autonomic nerves. Nerve lesions are induced by deposits of amyloid fibrils and treatment approaches for neuropathy are challenging. Involvement of cranial nerves and atrophy in facial muscles is a real concern i...

various studies have been conducted to study the relationship between job involvement and organizational citizenship behavior but a very little work have been done to study the impact of both job involvement and organizational commitment on “organizational citizenship behavior”. thus the purpose of the study is to find out the relationship between job involvement, organizational commitment and ...

The synthetic retinoid N-(4-hydroxyphenyl)retinamide (4HPR) has shown potential as a chemopreventive and therapeutic agent. The ability of 4HPR to enhance production of reactive oxygen species (ROS) leading to apoptosis has been suggested as a possible mechanism underlying these effects. We explored the possibility that ROS induction by 4HPR involves the small GTPase Ras-related C3 botulinum to...

A 71-year-old Japanese man was admitted on 24 January 2005 because of fever, arthralgia, chest pain and dyspnea. He had suffered from cerebral infarction 2 years previously, and had been treated with ticlopidine (200mg/day) since then. On admission, his temperature was 37.4 C, and C-reactive protein (CRP) was elevated to 19.7mg/dl. Renal function was normal, and there was no proteinuria or micr...

Paeoniflorin (PF) is the principal component of Paeoniae radix prescribed in traditional Chinese medicine. The delayed neuroprotection induced by PF preconditioning and its underlying mechanisms were investigated in rat middle cerebral artery occlusion (MCAO) and reperfusion model. At a dosage of 20 or 40 mg/kg, PF preconditioning 48 h before MCAO followed by 24-h reperfusion significantly redu...

TNF-alpha is a pleiotropic cytokine activating several signaling pathways initiated at distinct intracellular domains of the TNF receptors. Although the C-terminal region is believed to be responsible for apoptosis induction, the functions of more membrane-proximal domains, including the domain that couples to neutral sphingomyelinase activation, are not yet fully elucidated. The roles of this ...
