Summary: Although the association between single PAHs exposure and telomere length has been studied, the relationship between mixed PAHs exposure and telomere length in the general population is still uncertain. This study analyzed 8 PAHs and their correlation with telomere length, finding that mixed PAHs exposure was negatively associated with telomere length. Specifically, 2-napthol and 2-fluorene concentrations showed a significant negative correlation with telomere length. These findings indicate that PAHs may have a negative impact on telomere length in the general population.

Summary: This study investigated the relationship between exposure to polycyclic aromatic hydrocarbons (PAHs) and hypertension, and found a positive dose-response relationship between high exposure to certain PAH metabolites and the risk of hypertension. Obese individuals with high PAH exposure were at greater risk for hypertension than individuals with low PAH exposure and normal BMI.

Summary: This study aims to examine the association between urinary polycyclic aromatic hydrocarbons (PAHs) and liver function parameters among the US population. Data from the National Health and Nutritional Examination Survey (NHANES) 2003-2016 were used, and a total of 2515 participants were included. Logistic regression analysis showed that increased 9-hydroxyfluorene was associated with elevated GGT levels. In conclusion, 9-hydroxyfluorene is associated with elevated GGT levels, and its effect is modified by other PAHs.

Summary: Male factors are involved in around 50% of infertility cases, with up to 40% being diagnosed as idiopathic. It is important to evaluate additional biomarkers for sperm quality, especially considering the increasing use of ART and declining semen parameters. This systematic review selected studies on telomere length as a potential male fertility biomarker. The results suggest that shorter sperm telomeres may be associated with altered semen parameters or male infertility, but further studies are needed to determine its role in assessing individual fertility.

Summary: This study suggests that exposure to polycyclic aromatic hydrocarbons (PAHs) in workers may lead to telomere shortening, while genetic variations in the TEP1 gene could affect telomere length. Specifically, carrying the TEP1 rs1760903 CC genotype may be protective against telomere shortening. These findings highlight the roles of environmental factors and genetic variations in telomere damage, providing a basis for early detection of susceptible populations and establishment of occupational standards.

Summary: This study found that traveling from Los Angeles to Beijing led to significant increases in the concentrations of alkyl-naphthalene and alkyl-phenanthrene metabolites in urine samples, with different concentration ratios indicating relative exposure contributions from petrogenic and pyrogenic sources. These results suggest that 2-PHECA to hydroxy-phenanthrene ratio could be used as an index to reflect the sources of exposure to PAHs.

Summary: This study evaluated the association between internal exposure to polycyclic aromatic hydrocarbons (PAHs) and urinary iodine concentration with thyroid volume in school-age children in Guangzhou, China. The results showed a significant positive association between urinary hydroxylated PAHs and thyroid volume. Additionally, urinary PAHs were also linked to urinary iodine, and iodine mediated the relationship between PAHs and thyroid volume.

Summary: The study revealed that microglia-derived TNF-α plays a crucial role in regulating the activation of Muller cells during retinal neurodegeneration. TNF-α led to increased expression of GFAP and proinflammatory factors in Muller cells, while anti-TNFR1 and NF-κB inhibitor could reverse these changes.

Summary: Assessing a humanitarian transportation network early after a disaster is crucial for reducing casualties. Drones are considered for the assessment operations due to their potential. However, a novel challenge arises in the drone arc routing problem where drones can travel off the road network. To address this challenge, a graph transformation technique and a robust team orienteering problem with uncertain assessment time are proposed. The problem is solved efficiently using path-based reformulation and Lagrangian decomposition, and an exact branch-and-price framework is applied.

Summary: The age-hardening behavior of the Al-7Si-0.5Mg alloy was studied with different sizes and distributions of Si phase. The specimen with fine and homogeneous Si exhibited accelerated age-hardening kinetics and higher hardness compared to the specimen with coarse and clustered Si, attributed to the higher dislocation density caused by thermal contraction mismatch. The overlapping of the plastically-affected zone of adjacent Si in the specimen with large and clustered Si resulted in reduced volume fraction of the plastically-affected zone, lower dislocation density, and slower age-hardening kinetics. The relationship between Si radius and critical inter-particle spacing for minimizing interaction and maximizing dislocation density and age-hardening kinetics was established.

Summary: This review summarizes the current knowledge about the role and potential mechanisms of clock genes in regulating spermatogenesis. Rhythmic oscillation in semen parameters and physiological events of spermatogenesis have been observed. Disturbances in clock gene expression due to genetic mutations or environmental changes can significantly impair spermatogenesis, although the mechanisms of spermatogenesis regulation by clock genes remain unclear.

Summary: This study investigated the contribution of ambient air pollutants-induced semen damage to infertility risk by identifying the dose-response relationship between pollutants and semen parameters and susceptibility window. The results showed that multiple air pollutants, including SO2, O3, PMs, and NO2, were negatively associated with progressive motility, total motility, and sperm morphology. The analysis also revealed a mediating effect of sperm normal morphology in the association between SO2 and infertility. These findings suggest that air pollutants may affect semen quality and increase the risk of infertility.
