Autophagy is a crucial process for cells to maintain homeostasis and survival through degradation of cellular proteins and organelles, including mitochondria and endoplasmic reticula (ER). We previously demonstrated that temozolomide (TMZ), an alkylating agent for brain tumor chemotherapy, induced reactive oxygen species (ROS)/extracellular signal-regulated(More)
Methylmercury (Met-Hg) and ethylmercury (Et-Hg) are powerful toxicants with a range of harmful neurological effects in humans and animals. While Met-Hg is a recognized trigger of oxidative stress and an endocrine disruptor impacting neurodevelopment, the developmental neurotoxicity of Et-Hg, a metabolite of thimerosal (TM), has not been explored. We(More)
Cerebral ischemia is a leading cause of mortality and morbidity worldwide, which results in cognitive and motor dysfunction, neurodegenerative diseases, and death. Evodiamine (Evo) is extracted from Evodia rutaecarpa Bentham, a plant widely used in Chinese herbal medicine, which possesses variable biological abilities, such as anticancer, anti-inflammation,(More)
BACKGROUND No single precise qualitative method is recommended for evaluating the severity of aortic regurgitation (AR). Quantitative methods for AR assessment are, typically, cumbersome and time-consuming. The purpose of this study was to develop a more comprehensive method for predicting the severity of AR. METHODS In all, 79 patients with normal left(More)
We previously showed that progesterone (P4) inhibits the proliferation of rat aortic smooth muscle cells (RASMC). Here, we further demonstrate that P4 at physiologic levels (5-500 nM) concentration-dependently inhibited migration of cultured RASMC. The effect is blocked by pretreatment with progesterone receptor (PR) antagonist, RU486. The P4-induced RASMC(More)
Sinus of Valsalva aneurysm accounts for only 1% of congenital cardiac anomalies. Sinus of Valsalva aneurysm can cause aortic insufficiency, coronary artery flow compromise, cardiac arrhythmia, or aneurysm rupture. A 44year-old male presented with a 3-month history of palpitation and exertional dyspnea. Cardiac auscultation revealed a grade III/VI ‘‘to and(More)
The risks of surgery and its clinical outcome are of great importance for both patients and physicians when choosing coronary artery bypass (CABG) surgery for coronary artery disease. The purpose of the current study was to clarify the relationship between serum B-type natriuretic peptide (BNP) and patient clinical outcome. Seventy-six eligible patients who(More)
In the present study, we examined the effect of perinatal Escherichia coli lipopolysaccharide (LPS) exposure on the developing rat cerebellum and tested the hypothesis that maternal infections impact brain structure and function by mechanisms involving increase in oxidative stress and changes in brain type 2 iodothyronine deiodinase (D2)- and thyroid(More)
BACKGROUND The objective of this study was to assess the feasibility and safety of heparin-free veno-venous extracorporeal life support (VV ECLS) as a means of salvaging polytrauma patients with life-threatening hypoxemia. METHODS This is a retrospective observational study on 7 consecutive trauma patients who underwent VV ECLS for severe chest trauma(More)
