Far-infrared protects vascular endothelial cells from advanced glycation end products-induced injury via PLZF-mediated autophagy in diabetic mice.

The accumulation of advanced glycation end products (AGEs) in diabetic patients induces vascular endothelial injury. Promyelocytic leukemia zinc finger protein (PLZF) is a transcription factor that can be activated by low-temperature far-infrared (FIR) irradiation to exert beneficial effects on the vascular endothelium. In the present study, we investigated the influence of FIR-induced PLZF activation on AGE-induced endothelial injury both in vitro and in vivo.

Theoretical study on aluminum carbide endohedral fullerene-Al4C@C80.

The possibility of a new endohedral fullerene with a trapped aluminum carbide cluster, Al(4)C@C(80)-I( h ), was theoretical investigated. The geometries and electronic properties of it were investigated using density functional theory methods. The Al(4)C unit formally transfers six electrons to the C(80) cage which induces stabilization of Al(4)C@C(80).

An association study between PPP1R1B gene and schizophrenia in the Chinese population.

Schizophrenia has been linked with dysfunctions of glutamatergic, dopaminergic, and serotonergic neurotransmission. Dopamine- and cAMP-regulated phosphoprotein of relative molecular mass 32 kDa (DARPP-32), encoded by PPP1R1B (protein phosphatase 1, regulatory/inhibitor subunit 1B) gene, is enriched in neostriatal medium spiny neurons. It plays a key regulator role in dopaminergic and glutamatergic signaling pathways.

The PIP5K2A gene and schizophrenia in the Chinese population--a case-control study.

Results from a number of molecular and pharmacological studies suggest that the phosphatidylinositol-4-phosphate 5-kinase IIalpha (PIP5K2A) gene may be involved in the development of schizophrenia. A recent family-based transmission disequilibrium test in the German and Israeli populations found that four single nucleotide polymorphisms, rs1417374, rs10828317, rs746203 and rs8341 in this gene or nearby intergenic regions are significantly associated with schizophrenia. The objective of our study was to investigate whether these four SNPs are also associated with schizophrenia in the Chinese population.
