Salidroside ameliorates hypoxic pulmonary hypertension by regulating the two-pore domain potassium TASK-1 channel.

Background: Hypoxic pulmonary vasoconstriction (HPV) is a reflex constriction of vascular smooth muscle. This study aims to investigate the role of Salidroside (Sal) in pulmonary arterial dilatation and the potential mechanism of Sal regulating hypoxic pulmonary hypertension in vitro and in vivo.

Methods: A rat model of hypoxic pulmonary hypertension (HPH) was constructed using hypoxic chamber.

ALDH2 attenuates ischemia and reperfusion injury through regulation of mitochondrial fusion and fission by PI3K/AKT/mTOR pathway in diabetic cardiomyopathy.

The function of mitochondrial fusion and fission is one of the important factors causing ischemia-reperfusion (I/R) injury in diabetic myocardium. Aldehyde dehydrogenase 2 (ALDH2) is abundantly expressed in heart, which involved in the regulation of cellular energy metabolism and stress response. However, the mechanism of ALDH2 regulating mitochondrial fusion and fission in diabetic myocardial I/R injury has not been elucidated.

DHF-7 Ameliorates Behavioral Disorders and White Matter Lesions by Regulating BDNF and Fyn in a Mouse Model of Schizophrenia Induced by Cuprizone and MK-801.

Background: Schizophrenia is a psychiatric disorder including multiple clinical symptoms such as severe psychosis and cognitive dysfunction. DHF-7 is a novel dihydroflavanone derivative that was designed and synthesized to treat schizophrenia. This study aimed to investigate the effects and mechanisms of DHF-7 in a mouse model of schizophrenia induced by a combination of cuprizone and MK-801.

Genome-wide CRISPR/Cas9 screening identifies CARHSP1 responsible for radiation resistance in glioblastoma.

Glioblastomas (GBM) is the most common primary malignant brain tumor, and radiotherapy plays a critical role in its therapeutic management. Unfortunately, the development of radioresistance is universal. Here, we identified calcium-regulated heat-stable protein 1 (CARHSP1) as a critical driver for radioresistance utilizing genome-wide CRISPR activation screening.

Behavioral and neurobiological changes in a novel mouse model of schizophrenia induced by the combination of cuprizone and MK-801.

Schizophrenia is a mental illness characterized by episodes of psychosis, apathy, social withdrawal, and cognitive impairment. White matter lesions and glutamatergic hypofunction are reported to be the key pathogeneses underlying the multiple clinical symptoms of schizophrenia. Cuprizone (CPZ) is a copper chelator that selectively injures oligodendrocytes, and MK-801 is an antagonist of the N-methyl d-aspartate (NMDA) receptor.

A novel flavanone derivative ameliorates cuprizone-induced behavioral changes and white matter pathology in the brain of mice.

Recent studies have shown that white matter lesions play an important role in the pathogenesis of schizophrenia. DHF-6 is a novel flavanone derivative synthesized in our laboratory. The purpose of the present study was to investigate the effects of DHF-6 on behavioral changes and white matter pathology in a 0.

Peripheral lung cancer: relationship between multi-slice spiral CT perfusion imaging and tumor angiogenesis and cyclin D1 expression.

The aim of this study was to investigate the relationship between 16-slice spiral CT perfusion imaging and tumor angiogenesis and cyclin D1 expression in patients with peripheral lung cancer. Fifty-eight patients with peripheral lung cancer underwent 16-slice spiral CT perfusion imaging. The CT perfusion imaging was analyzed for time density curve (TDC), perfusion parametric maps, and the respective perfusion parameters.
