Recent evidence has indicated that biological markers are essential in estimating the prognosis of patients with gliomas. The aim of this study was to determine the status and clinical significance of a novel tumor suppressor, PCDH9 (protocadherin 9) in glioma using tissue microarrays and immunohistochemistry. Normal brain tissue showed strong positive… (More)
We treated detonator-explosion-induced craniocerebral injury in rabbits with hyperbaric oxygen 1-24 hours post-injury. Expression of the apoptosis-regulating protein cytochrome c, the pro-apoptotic protein Bax and the apoptosis marker caspase-3 in the tissues surrounding the area of injury was significantly reduced, while that of the anti-apoptotic protein… (More)
In the present study, rabbits were treated with hyperbaric oxygen for 1 hour after detonator-blast- induced craniocerebral injury. Immunohistochemistry showed significantly reduced aquaporin 4 expression and adrenocorticotropic hormone expression in the pituitary gland of rabbits with craniocerebral injury. Aquaporin 4 expression was positively correlated… (More)
The purpose of this study was to investigate the effects of brain-derived neurotrophic factor (BDNF)-transfected bone marrow mesenchymal stem cells (BMSCs) on neural functional recovery and synaptophysin expression in rats with cerebral infarction (CI). A total of 120 healthy Sprague Dawley rats were randomly divided into sham group, control group, and… (More)
Union-Intersection Ant System is an optimization algorithm with multi-nest of ants cooperating with each other, whose goal is to identify the edges belonging to the solution of TSP (denoted as TSP-edge-set). It identifies a part of elements in TSP-edge-set by the intersection of several hero ants' tours (a hero ant is the one found the best tour in a nest)… (More)
This paper proves that counterexample of Heawood is four-colorable by using Tait’s methods and that counterexample of Tutte is also four-colorable by using Kempe’s chains. Authors discover formation mechanism of two-level Hamilton cycle in a 3-regular plane graph. It provides a new way for the non-computer proof of four-color problem.
Hypoxic preconditioning (HPC) increases the inherent tolerance of brain tissue suffering from severe hypoxia or ischemia insult by stimulating the protective ability of the brain. However, little is known concerning the effect of HPC on traumatic brain injury (TBI). We designed this study to investigate the effect of HPC on TBI and explore its underlying… (More)
