Causal relationship between type 2 diabetes and glioblastoma: bidirectional Mendelian randomization analysis.

As the prevalence of Type 2 Diabetes Mellitus (T2DM) and Glioblastoma (GBM) rises globally, the relationship between T2DM and GBM remains controversial. This study aims to investigate whether genetically predicted T2DM is causally associated with GBM. We performed bidirectional Mendelian randomization (MR) analysis using data from genome-wide studies on T2DM (N = 62,892) and GBM (N = 218,792) in European populations.

Prokaryotic expression of DFP1 and DFP2 in Dermatophagoides farinae and their responses to temperature stress.

The functions of highly expressed genes DFP1 and DFP2 in Dermatophagoides farinae remain unknown.

Reactive astrocytes may play a protective or harmful role in different diseases due to different phenotypes of astrocytes.

Case report of thrombotic thrombocytopenic purpura during pregnancy with a review of the relevant research.

Rationale: Thrombotic thrombocytopenic purpura (TTP) is a syndrome characterized by widespread blood vessel clotting and bleeding. It can affect individuals of any age but is more commonly observed in females, particularly during pregnancy. Pregnancy combined with TTP is a critical and rapidly progressing condition that is often misdiagnosed as an obstetric disorder like severe preeclampsia or HELLP syndrome.

CB1 receptor mediates anesthetic drug ketamine‑induced neuroprotection against glutamate in HT22 cells.

The anesthetic drug, ketamine (KTM) has been shown to induce therapeutic effects against major depressive disorder (MDD), however the related underlying mechanisms remain unclear. In the present study, HT22 neuronal cells were treated with glutamate to imitate oxidative stress injury in MDD, and it was hypothesized that the cannabinoid type 1 (CB1) receptor mediates KTM-induced neuroprotection via ameliorating mitochondrial function in glutamate-treated neuronal cells. Compared with the control, glutamate decreased cell viability and intracellular antioxidants, including glutathione (GSH), catalase and superoxide dismutase 2 levels, and inhibited mitochondrial function simultaneously.
