Viral studies on human brain culture retrieved from cold storage.
نویسنده
چکیده
Tissue cultures established from brain tissues of six patients with various chronic, degenerative diseases did not show evidence of viral agents. Sucrose gradient analysis of radioactively labeled culture fluid from two patients failed to reveal the presence of any incomplete or defective virus. Extracellular fluids from three brain cultures contained a factor able to stimulate deoxyribonucleic acid synthesis of Vero cells.

Generation of motor neurons from human amygdala-derived neural stem-like cells
Objective(s): Among several cell sources, adult human neural stem/progenitor cells (hNS/PCs) have been considered outstanding cells for performing mechanistic studies in in vitro and in vivo models of neurological disorders as well as for potential utility in cell-based therapeutic approaches. Previous studies addressed the isolation and culture of hNS/PCs from human neocortical and hippocampal...
متن کاملHuman brain slices for epilepsy research: Pitfalls, solutions and future challenges.
Increasingly, neuroscientists are taking the opportunity to use live human tissue obtained from elective neurosurgical procedures for electrophysiological studies in vitro. Access to this valuable resource permits unique studies into the network dynamics that contribute to the generation of pathological electrical activity in the human epileptic brain. Whilst this approach has provided insights...
متن کاملImpact of Salicylic Acid on Phenolic Metabolism and Antioxidant Activity in Four Grape Cultivars during Cold Storage
Salicylic acid (SA) plays an important role in the regulation of plant ripening and responses to abiotic stresses. In this study, the protective effect of SA on cold stress-caused oxidative damage in grape (Vitis vinifera L.) bunches was investigated during cold storage. Grape bunches treated with 2 mM SA and stored at 0°C with 85-90% RH for 30 days. Samples were selected from each treatment ...
متن کاملP-52: Brain-Derived Neurotrophic Factor Promotes The Development of Human Ovarian Early Follicles during Growth In Vitro
Background Cryopreservation of ovarian cortex is increasingly used to preserve fertility before cancer therapy. Recently, studies show that Brain-derived neurotrophic factor (BDNF) may be involved in oocyte maturation. Brain-derived neurotrophic factor (BDNF) is member of neurotrophin family that has anti-apoptotic effects on nervous system. Recent researches show that it also plays key role in...
متن کاملEvaluation of Adventitious Agents in MMR & Oral Poliomyelitis Vaccines
Background and Aims: Adventitious agents, especially viral agents are among the most important concerns in viral vaccines. Viral contamination of biological products may arise from the original source of the reagents such as, serum, trypsin, animal or human derived media components or cell culture and working seed or cross contamination of vaccine during production. In this study, adventitious ...
