Are heart rate variability and DNA methylation levels altered after short-term metal fume exposure among occupational welders : a repeated-measures panel study?
Acute decline of HRV was observed following exposure to welding PM2.5 and evidence for an epigenetic response of transposable elements to short-term exposure to high-level metal-rich particulates was reported.
Women with antisperm antibodies have several disadvantages to overcome in order to achieve successful IVF-ET, such as a low fertilization rate and poor quality of transferred embryos. However, a high implantation rate was observed in this group, even in women at advanced age. The occurrence of a cellular or humoral immune reaction against sperm may augment the uterine receptivity for the implantation of fertilized ova or blastocyst.
