Summary: This study aimed to investigate whether Benzo[a]pyrene (BaP) regulates lipid metabolism via the aryl hydrocarbon receptor (AhR). The results showed that BaP inhibited fat synthesis and oxidation while inducing inflammation by activating AhR, leading to dysfunction of white adipose tissue and metabolic complications.

Summary: Exposure to polycyclic aromatic hydrocarbon BaP accelerates lung cancer initiation and progression through AHR signaling and metabolic reprogramming. The study reveals that amino acid and fatty acid metabolism, along with AHR and PPAR-FATP1 signaling, could be potential therapeutic targets for intervening BaP-induced toxicity and related diseases. The novel findings of fatty acid accumulation and high correlations of AHR signaling with amino acid and fatty acid metabolism in BaP-exposed lung epithelial cells are highlighted.

Summary: This study investigates the possibility of a mechanism beyond post-translational modifications to regulate protein function. It shows that hydrogen sulfide (H2S) can bind to the active-site copper of Cu/Zn-SOD, enhancing electrostatic forces and facilitating electron transfer. The physiological relevance of this H2S effect is demonstrated in in vitro and in vivo models where the cardioprotective effects of H2S depend on Cu/Zn-SOD.

Summary: Nanozymes, nanomaterials with enzyme-mimicking activity, have attracted significant interest in biomedical applications, particularly in oxidative stress-mediated disorders. The challenge lies in designing nanozymes that can selectively differentiate between physiological oxidative stress and pathological oxidative stress and mediate appropriate redox reactions in cells, tissues, and organs. This review summarizes the advancements in redox-active nanozymes and their therapeutic significance in various disease models, such as cancer, neurodegeneration, and cardiovascular diseases. It also discusses the future prospects and challenges associated with the biomedical applications of nanozymes.

Summary: Cu/Zn superoxide dismutase (Sod1) catalyzes the breakdown of superoxide radicals into oxygen and hydrogen peroxide, which acts as a signaling molecule. In yeast, Sod1 is involved in a redox signaling pathway that connects nutrient availability to energy metabolism control. This pathway stabilizes plasma membrane kinases Yck1/2, promoting glycolytic growth and repressing respiration.

Summary: Studies on anurans have been conducted for over 40 years to evaluate the adverse effects of benzo(alpha)pyrene (B alpha P), showing genotoxic, hepatotoxic, and immunotoxic effects. This study aimed to assess whether the route of administration of B alpha P influences its effects on hepatic biomarkers, with morphological biomarkers being more significantly affected than biochemical ones. The exposure pathway and time both modulate the effects of B alpha P on hepatic biomarkers in anurans.

Summary: The metallation status of human Cu/Zn superoxide dismutase 1 (SOD1) is crucial in the development of amyotrophic lateral sclerosis (ALS). Mutations at the ALS-linked positions H63R and K136A significantly affect dimer dynamics, leading to demetallation and potential ALS toxicity. This study highlights the potential use of atomistic simulations in studying disease variants related to SOD1.

Summary: The study demonstrated that exposure of colon cancer cells to benzo(a)pyrene resulted in dose-dependent decrease in cell growth, cytotoxicity, and modulation of the cell cycle, as well as elevated concentrations of BaP metabolites contributing to DNA damage and stable DNA adduct formation. Additionally, the expression of phase I biotransformation enzymes showed BaP concentration-dependent changes, while phase II enzymes remained relatively stable. This study highlights the role of BaP biotransformation in cytotoxicity, proliferation of tumor cells, and alteration of gene expression.

Summary: Exposure to high levels of PM2.5 was found to be significantly associated with an increased risk of self-reported CVD at enrollment, particularly among individuals with clinical risk factors such as hypertension, hypercholesterolemia, and smoking. Black participants were more likely to live in areas with higher PM2.5 concentrations and had a higher prevalence of clinical risk factors, indicating a greater future risk of CVD.

Summary: This study investigated the effects of prenatal exposure to benzo[a]pyrene (BaP) on embryonic gonads and potential mechanisms for increased ovarian tumor risk. The results showed that developing ovaries are more sensitive than testes to prenatal BaP exposure, which may be related to higher concentrations of BaP metabolites in female embryos.

Summary: This article provides a systematic review of studies conducted between 2000 and 2020 on the training of medical students and residents to address the health needs of sexual and gender minorities (SGM). The review found that training had a positive impact on knowledge, comfort, attitudes, confidence, and skills in working with SGM patients. However, no studies examined the impact of training on patient outcomes.

Summary: Physician-identified barriers to PrEP provision include Purview Paradox, Patient Financial Constraints, Risk Compensation, and Concern for ART Resistance. Recommendations for increasing PrEP knowledge and competence among physicians and students include adopting HIV risk assessment as standard care, improving physician ability to identify PrEP candidates, enhancing interest in and ability to encourage PrEP uptake, and increasing utilization of continuous care management for retention and adherence.

Summary: Pre-Exposure Prophylaxis (PrEP) is an effective method of HIV prevention for certain high-risk populations, but less than 50,000 individuals currently use this regimen. A survey of medical schools in the United States found that only a minority offered PrEP education, with limited training for LGBT patients. Most schools used didactic sessions to deliver PrEP content, and students were more prepared to provide PrEP to MSM compared to other high-risk patients.
