Neural stem cells (NSCs) can differentiate

into neurons, astrocytes and oligodendrocytes. The purpose of this study was to evaluate the therapeutic effects of transplanting NSCs into rats which have the animal model of Alzheimer’s disease (AD). NSCs from the hippocampus and NSCs-derived glial cells labeled with 5′-Bromo-2′-deoxyuridine (BrdU) were transplanted into two groups of transected rat basal forebrain. Nestin staining, glial fibrillary acidic protein (GFAP) staining and double-labeling immunofluorescence were used to detect the engrafted cells in the basal forebrain. Immunohistochemical detection of p75(NGFR) showed that the number of cholinergic neurons of the NSCs-transplanted group was significant higher than that of the glia-transplanted group in medial septum (MS) and vertical PF-02341066 chemical structure diagonal

branch (VDB) (P < 0.05). Learning and memory abilities were also measured by Y-maze test. The results indicate that transplanted NSCs can differentiate into cholinergic neurons, which may play an important role in the therapeutic effects of transplanted NSCs.

“Combined open and endovascular hybrid procedures can be used to treat complex aortic pathology. This article reports a five-stage hybrid repair for a complex thoracoabdominal aneurysm with dissection in a 57-year-old man. To our knowledge, this is selleck kinase inhibitor Eltanexor supplier the first reported case of replacement and exclusion of the entire native human

aorta from the root to the iliac bifurcations using a combined open and endovascular approach without neurologic complication. Bilateral hypogastric and femoral circulation was preserved. Aggressive spinal protective measures, including spinal drainage, motor-evoked potentials, and prevention of intraoperative and perioperative hypotension, were used during this staged approach.

“Bradykinin has been shown to increase the permeability of blood-tumor barrier (BTB) selectively. This study was performed to determine whether tumor necrosis factor-alpha (TNF-alpha) was involved in the regulation of this biological process. We found that the levels of TNF-alpha mRNA and heat shock factor-1 (HSF1) protein in C6 cells were markedly up-regulated by bradykinin via real-time RT-PCR and Western blot methods. And the most obvious increase of HSF1 protein and TNF-alpha mRNA in C6 cells were observed at 5 min and 10 min of bradykinin perfusion, respectively. In addition, the radioactivity of TNF-alpha in C6 cells’ culture fluid also mostly increased at 15 min of bradykinin perfusion. And the Evans blue content of brain tumor tissues in rats and the concentration of TNF-alpha reached the maximum at 15 min of bradykinin perfusion.
