Article Synopsis
- * The study focuses on MnGe/Si quantum dots (QDs) with a Curie temperature above room temperature, grown using ion beam co-sputtering, where increased Mn doping leads to self-assembly through the Stranski-Krastanov growth mode.
- * The research indicates that the Curie temperature rises with Mn doping, peaking at 321 K, and can increase to 383 K after appropriate annealing, suggesting that higher germanium content and residual strain in the QDs contribute to maintaining the ferromagnetic
As a crucial factor in male reproduction, androgens may represent an intermediate biological mechanism linking metal exposure with effects on semen quality. This study aimed to investigate the association between metal exposure and semen quality, and to assess the mediating role of seminal androgens between metal exposure and semen quality. We investigated the presence of 10 metals in semen and assessed their effect on semen quality in 1136 men recruited from a hospital in Shenzhen, China.
View Article and Find Full Text PDFApolipoprotein C2 (ApoC2) is an important member of the apolipoprotein C family and functions as a major activator of lipoprotein lipase (LPL). In cardiovascular and cerebrovascular systems, the lipolytic activity of the LPL-ApoC2 complex is critical for the metabolism of triglyceride-rich lipoproteins and contributes to the pathogenesis of ischemic stroke (IS). However, the regulation of ApoC2 in IS development remains unclear.

Objective: To explore the mediating effect of oxidative stress on the relationship of heavy metal exposure with semen quality.
Methods: Urinary levels of three oxidative stress markers, semen quality, and urinary arsenic, cadmium and lead were examined among 1020 men.
