The study was designed to investigate the effects of ischemic preconditioning (IP) on permeability of blood-brain barrier (BBB) and expression of matrix metalloproteinase-9 (MMP-9) in subsequent ischemic hemisphere. Rats were divided into four groups, one group was used as control, and the other three groups were given three different pretreatments: the(More)
Molecular mechanisms underlying the pathogenesis of meningioma are not fully elucidated. In this study, we established differential gene expression profiles between meningiomas and brain arachnoidal tissue by using Affymetrix GeneChip Human U133 Plus 2.0 Array. KEGG pathway analysis demonstrated that PI3K/Akt and TGFβ signaling pathways were up-regulated in(More)
BACKGROUND Little is known about the biological behavior of Xp11.2 translocation renal cell carcinomas (RCCs) as few clinical studies have been performed using a large sample size. METHODS This study included 103 consecutive young adult patients (age ≤ 45 years) with RCC who underwent partial or radical nephrectomy at our institution from 2008 to 2013.(More)
Despite of the immense breakthroughs of induced pluripotent stem cells (iPSCs), clinical application of iPSCs and their derivates remains hampered by a lack of definitive in vivo studies. Here, we attempted to track iPSCs-derived neural stem cells (NSCs) in the rodent and primate central nervous system (CNS) and explore their therapeutic viability for stem(More)
BACKGROUND Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide with poor prognosis due to resistance to conventional chemotherapy and limited efficacy of radiotherapy. There is an urgent need to develop novel biomarkers for early diagnosis, as well as to identify new drug targets for therapeutic interventions. PATIENTS AND(More)
Mouse adenovirus-type 1 (MAV-1) has recently been shown to cause a fatal hemorrhagic encephalopathy in certain strains of mice whereas other strains are resistant. Morbidity is associated with a productive infection of cerebrovascular endothelial cells, resulting in necrosis of the vasculature, infarction, hemorrhage and death within 4 - 6 days. Previous(More)
Papillary meningioma is a rare subtype of malignant meningiomas, which is classified by the World Health Organization as Grade III. Because of lack of large sample size case studies, many of the specific characteristics of papillary meningioma are unclear. This study investigated by retrospective analysis the clinical, radiological and his-topathological(More)
Radiation pneumonitis (RP) is an important dose-limiting toxicity during thoracic radiotherapy. Previous investigations have shown that curcumin is used for the treatment of inflammatory conditions and cancer, suggesting that curcumin may prevent RP and sensitize cancer cells to irradiation. However, the clinical advancement of curcumin is limited by its(More)
In this study, we investigated the association between common variants in the matrix metalloproteinase-3 (MMP-3) gene and the risk of developing sporadic brain arteriovenous malformation (BAVM). We performed genotyping analyses for five single nucleotide polymorphisms (SNPs) in MMP-3 in a case-control study involving 319 Chinese patients with BAVM and 333(More)
OBJECT The goal of this study was to combine the use of ultrasound contrast agents with intraoperative ultrasound techniques to identify intraoperatively a patient's vascular anatomy, including feeding arteries and draining veins of an intracranial arteriovenous malformation (AVM). METHODS The authors examined 12 consecutive patients with AVMs that had(More)
