The metal tetraphosphides (MP4, M = 3d transition metals) exhibit the layered‐structure character, in which the metal atoms chains are sandwiched between the P4 ²⁻ layers, and have attracted considerable interest due to the outstanding physical and chemical properties, such as the good electrical conductivity and the high lithium capacity. The CrP4...

Background: Male infertility is a complex disease caused by a combination of genetic, environmental, and lifestyle factors. Abnormal epigenetic programming has been proposed as a possible mechanism compromising male fertility. Recent studies suggest that aberrant imprinting in spermatozoa in a subset of infertile men is a risk factor for congenita...

Tt/tc: OR, 3.18; 95% CI, 1.54-6.56; TC vs. TT: OR, 1.65; 95% CI, 1.27-2.03). However, no overall association was observed between the other two polymorphisms of eNOS (G894T and 4a4b) and male infertility. Stratified analysis showed that significantly strong association between T786C polymorphism and semen quality was present in all three types of...

Infertility affects about 17% couples, and males contribute to half of the cases. Compared with independent effects of genetic and environmental factors, interactions between them help in the understanding of the susceptibility to male infertility. Thus, we genotyped 25 polymorphisms, measured 16 urinary chemical concentrations and explored interac...

Human X chromosome has higher densities of microRNAs (miRNAs) compared to the average densities on autosomes. Given that numbers of X-linked miRNAs can escape from meiotic sex chromosome inactivation (MSCI) silencing, it is proposed that X-linked miRNAs may play critical roles in the process of spermatogenesis. To test the hypothesis, we performed...
