To study genetic diversity and drug resistance of HIV-1 CRF_BC among drug users in Guangdong Province, 67 circulating recombinant form 07_BC (CRF_07BC) and 32 circulating recombinant form 08_BC(CRF_08BC) HIV-1 pol genes were amplified and sequenced. In the protease gene region (PR), 31 CRF_08BC isolates were amplified and 10 high polymorphism positions were(More)
Neural stem cells (NSCs) possess high potencies of self-renewal and neuronal differentiation. We explored here whether transplantation of human NSCs cloned by v-myc gene transfer, HB1.F3 cells, is a feasible therapeutic option for Parkinson's disease. In vivo, green fluorescent protein-labeled HB1.F3 cells (200,000 viable cells in 3 microl of PBS) when(More)
Stroke remains a major cause of death in the US and around the world. Over the last decade, stem cell therapy has been introduced as an experimental treatment for stroke. Transplantation of stem cells or progenitors into the injured site to replace the nonfunctional cells, and enhancement of proliferation or differentiation of endogenous stem or progenitor(More)
We monitored alterations in cerebral blood flow (CBF) and blood-brain barrier (BBB) permeability following middle cerebral artery occlusion (MCAo) and intrastriatal transplantation of mouse bone marrow stromal cells (BMSCs) or saline infusion in adult Sprague-Dawley rats. Laser Doppler and Evans Blue assay revealed that BMSC grafts dose-dependently restored(More)
BACKGROUND Minocycline, a second-generation tetracycline with anti-inflammatory and anti-apoptotic properties, has been shown to promote therapeutic benefits in experimental stroke. However, equally compelling evidence demonstrates that the drug exerts variable and even detrimental effects in many neurological disease models. Assessment of the mechanism(More)
A systematic study on the structure and function of Glucose-6-phosphate dehydrogenase (G6PD) variations was carried out in China. A total of 155,879 participants were screened for G6PD deficiency by the G6PD/6PGD ratio method and 6,683 cases have been found. The prevalence of G6PD deficiency ranged from 0 to 17.4%. With informed consent, 1,004 cases from 11(More)
Gene transfection with Notch 1 intracellular domain and subsequent growth factor treatment stimulate neuron-like differentiation of bone marrow stromal cells (BMSCs). Here, we examined the potential of transplanting Notch-induced BMSCs to exert therapeutic effects in a rat model of chronic ischemic stroke. In experiment 1, Notch-induced rat BMSCs were(More)
This review article discusses recent progress on the use of teratocarcinoma-derived Ntera2/D1 neuron-like cells (NT2N cells, also called hNT cells) as graft source for cell transplantation in stroke. Laboratory evidence has demonstrated the therapeutic potential of NT2N cells in stroke therapy. Phase I and II clinical trials have shown the cells'(More)
OBJECTIVE To investigate the different effects of an angiotensin II type 1 (AT(1)) receptor antagonist, losartan, and an angiotensin converting enzyme (ACE) inhibitor, fosinopril, on cardiomyocyte apoptosis, myocardial fibrosis, and angiotensin II (Ang II) in the left ventricle of spontaneously hypertensive rats (SHRs). METHODS SHRs of 16-week-old were(More)
Nurr1 has been implicated as a transcription factor mediating the endogenous neuroprotective mechanism against stroke. We examined the in vivo and in vitro properties of a new human embryonic carcinoma Ntera-2 cell line carrying the human Nurr1 gene (NT2N.Nurr1). Adult Sprague-Dawley rats underwent experimental stroke initially and 14 days later were(More)
