Summary: There is a dose-response relationship between plasma zinc (Zn) and risk of Hyperhomocysteinemia (HHcy) in patients in Northeast China, with a threshold level of 83.89 mu mol/L for reducing HHcy risk. Therefore, individuals in this region, especially those with the MTHFR 677TT polymorphism, should pay attention to their plasma Zn and homocysteine levels.

Summary: The study found a significant dose-dependent association between MTHFR A1298C and PCOS, with MTRR A66G showing nominal association. Mutations in both MTHFR A1298C and MTRR A66G were significantly associated with the homocysteine level. Mediation analysis suggested that the effect of MTHFR A1298C on PCOS is mediated by homocysteine.

Summary: Genetic variation in the MTHFR gene may contribute to the development of cerebral infarction. This study aimed to analyze the effect of MTHFR gene polymorphism on serum lipid and homocysteine levels among Chinese Han population with cerebral infarction. Results showed that the TT genotype and T allele frequencies were significantly higher among CI patients, and CT/TT carriers had higher homocysteine levels and lower HDL-C and ApoA-I levels.

Summary: The study investigated the association between /WHR C677T, MTHFR A1298C, and MTRR A66G polymorphisms and birth defects in the southern Chinese population. Genotyping was conducted and association analysis revealed that these polymorphisms were not significant risk factors for predicting birth defects. Despite differences in genotype distribution and effects on folic acid and homocysteine levels, the polymorphisms did not play a critical role in predicting birth defects in this study.

Summary: This study found that patients with AGA have higher levels of SH, and the C677T polymorphism of MTHFR is associated with an increased risk of CHD. The mutant T allele is correlated with hyperhomocysteinemia and an increased risk of CHD in AGA patients, highlighting the importance of cardiac evaluation and follow-up in this population.

Summary: This study in China investigated the impact of high homocysteine levels and PM2.5 air pollution on atherosclerosis. The results showed that high homocysteine levels were associated with increased carotid intima-media thickness in areas with high PM2.5 pollution. This finding has important implications for atherosclerosis prevention strategies in China.

Summary: This study investigated the association between MTHFR gene polymorphisms and homocysteine levels in pregnancy-induced hypertension. Results showed that patients with pregnancy-induced hypertension had higher Hcy levels and increased proportion of TT genotype at the MTHFR gene C677T locus, which correlated with higher incidence of abnormal pregnancy outcomes.

Summary: The rationale and importance of folic acid supplementation during pregnancy for preventing fetal congenital defects are widely accepted. Adequate folate levels can reduce the risk of spontaneous abortions and support normal placental blood flow, promoting appropriate fetal growth. Additionally, there is emerging evidence that long-term folic acid supplementation can effectively prevent preeclampsia, a complication unique to humans during pregnancy that contributes to worldwide maternal and perinatal mortality. Folate supplementation helps to decrease elevated levels of homocysteine, which is associated with the risk of preeclampsia.

Summary: This study investigated the relationship between homocysteine levels and MTHFR C677T polymorphisms with acute ischemic vascular events and focused on the differential effects of the MTHFR C677T polymorphisms on the burden and location of AMI and ACI. The results showed that homocysteine levels were associated with MTHFR C677T polymorphisms and acute ischemic vascular events, but did not differentially affect the burden and location of AMI and ACI.

Summary: High-dose folic acid supplementation in men with male infertility undergoing IVF-ICSI has been shown to increase the biochemical pregnancy rate, reduce DNA fragmentation, and potentially improve the clinical pregnancy rate. Despite no observed changes in sperm characteristics, folic acid supplementation appears to have a positive impact on IVF-ICSI outcomes for male infertility patients.

Summary: Healthcare professionals in a French university hospital lack comfort in managing trans people, mainly due to a lack of knowledge and training in this area, rather than disagreement with the need for transgender healthcare.

Summary: Efficient elimination of apoptotic substrates is crucial for tissue homeostasis in the retina, testis, and ovaries, and is achieved by phagocytic cells like RPE, Sertoli cells, and GC. Disruption of this process can lead to functional ablation and vision loss in the retina, and compromised fertility in males and females. Cooperation between TAM RTKs, autophagy-related proteins, LAP, and TLR plays a pivotal role in maintaining tissue homeostasis and preventing functional ablation of these tissues.

Summary: The study focused on the ultrastructure of the pathological retina in HD R6/1 mice and discovered the presence of myelinosomes, abnormal organelles enriched with mutant Huntingtin protein, which may contribute to the spread of HD in the retina. Exploring the presence of myelinosomes in ocular fluids could potentially serve as an additional biomarker for HD diagnostics.

Summary: Extracellular Vesicles (EVs) are membrane-limited particles secreted by healthy and cancerous cells, containing proteins, lipids, metabolites and nucleic acids, mediating various biological functions. In the male genital tract, three subtypes of EV have been described, differing in secretion location such as the testis, prostate or epididymis. EVs can fuse together, deliver information to recipient cells like spermatozoa, and potentially modulate transmitted information to the next generation through epigenetic changes.

Summary: EDCs can influence gene expression through epigenetic alterations, leading to transgenerational inheritance of traits. Mechanisms such as DNA methylation, acetylation, histone modification, RNA-mediated effects, and extracellular vesicle effects have been implicated. While limited effects on sperm epigenetics have been described, there has been growing interest in this issue in recent years.

Summary: This research explores women's perceptions of male contraception and finds that the majority of women support men taking responsibility for contraception. However, the proportion decreases after women are informed about existing and developing male contraceptives. The most acceptable method for women is the male pill, but there is a lack of knowledge about male contraception.
