Results of toxicology studies on EB were used to evaluate estrogen, androgen, thyroid, and steroidogenic (EATS) endpoints by a Weight of Evidence (WoE) methodology, as required by U.S. EPA and OECD guidelines for evaluating a chemical's endocrine disruptive potential. The WoE method involved problem formulation, systematic literature search and selection, data quality evaluation, relevance weighting of endpoint data, and application of specific interpretive criteria. Data on EB were sufficient to assess its effects on endpoints that would be expected to respond to chemicals that operate via EATS modes of action (MoAs) in various screening assays (Tier 1) and toxicity tests (Tier 2) that evaluate reproduction, development, and sub-chronic and chronic toxicity. In those studies, EB produced a pattern of responses inconsistent with the responses that would be expected for hormones and chemicals known to operate via EATS MoAs. Endocrine-sensitive endpoints that respond to EB administration generally do so only at dose levels above its kinetic maximum dose, indicating a lack of relevance to potential effects at lower dose levels in either the test species or humans. This comprehensive WoE evaluation demonstrates that EB lacks the potential to exhibit endocrine disruptive properties and cannot be deemed an endocrine disruptor or potential endocrine disruptor. Because this WoE evaluation was based largely on Tier 2-level studies of the type considered by the U.S. EPA and OECD to be more definitive than results of Tier 1 EDSP screening results, no additional useful information would be obtained by subjecting EB to further endocrine screening. As such, further endocrine screening of EB would be unjustified from animal welfare perspectives. This analysis supports a regulatory decision to halt further testing of EB for endocrine disruption unless unique and compelling data to the contrary arise.

Hence, adolescents are particularly vulnerable to external stressors, underscoring the need to safeguard their well-being and prioritize mental health interventions. The coronavirus disease (COVID-19) pandemic caused a global crisis with profound societal disruptions, and led to lasting impact on global public health, disproportionately affecting vulnerable populations, including adolescents. In view of the unique developmental challenges faced by adolescents, it is imperative to assess the growing burden of mental health issues exacerbated by the pandemic. This review synthesizes existing evidence on the emerging mental health challenges faced by adolescents in the United Kingdom (UK) as exacerbated by the COVID-19 pandemic. A systematic literature search was conducted using PubMed, ScienceDirect, MEDLINE, and SpringerNature databases, resulting in the selection of ten high-quality studies. A thematic analysis of the collected data revealed that depression and anxiety were the most frequently reported mental health conditions among adolescents. These conditions were particularly prevalent among adolescents who were from low-income households, those with pre-existing mental health disorders, adolescents experiencing household conflicts, females, and those who provided self-reported data. Several key risk factors were identified, including family and peer relationships, academic pressures such as examinations and grades, financial constraints within households, and the corruptive influence of social media. The findings underscore the urgency of targeted mental health interventions tailored to the specific needs of adolescents in the U.K. By addressing the identified risk factors, mental health professionals, policymakers, and educators can develop more effective strategies to mitigate the psychological impact of the pandemic on this vulnerable population. This study contributes to the evolving body of literature and emphasizes the need for evidence-based policies to foster overall well-being and resilience in adolescents navigating post-pandemic challenges.</p>","PeriodicalId":12247,"journal":{"name":"EXCLI Journal","volume":"24 ","pages":"508-523"},"PeriodicalIF":3.8,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12078782/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144076840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although coronary atherosclerosis is a major cause of IHD, many patients with angina or myocardial ischemia do not have obstructive coronary heart disease and impairment of the coronary microcirculation has been increasingly implicated as a relevant cause of IHD. Therefore, coronary microvascular dysfunction (CMD) refers to a term covering a wide spectrum of structural and functional alterations which affect the coronary microcirculation leading to myocardial ischemia and angina. The advent of non-invasive and invasive functional tests has exponentially broadened the ability to recognize CMD and delineate related clinical and biochemical features. Despite major advances in diagnosing and stratifying this condition, therapeutic strategies remain limited and poorly defined. In this review, we will provide an overview of the pathophysiology and the diagnostic evaluation of CMD across the spectrum of cardiovascular diseases.

TMZ-induced DNA damage is counteracted by the repair enzyme O-6-methylguanine-DNA methyltransferase (MGMT), promoting tumor recurrence. Targeting oxidative phosphorylation (OXPHOS), essential for cellular energy production, offers a potential therapeutic strategy to overcome TMZ resistance and improve GBM treatment outcomes. Gboxin, a small-molecule drug, selectively inhibits OXPHOS by targeting complex V, with minimal toxicity to normal cells. It accumulates in the mitochondria of GBM cells, exploiting their high membrane potential and pH, thereby inhibiting cell proliferation. This study evaluates Gboxin's efficacy in TMZ-resistant (TMZ-R) GBM. Results show that Gboxin suppresses the growth of both TMZ-sensitive and TMZ-R GBM cells by inhibiting proliferation, inducing apoptosis, and reducing OXPHOS activity. These findings were confirmed in an <i>in vivo</i> model, highlighting Gboxin as a promising therapeutic for both TMZ-sensitive and TMZ-R GBM.

The present work focused on determining whether phosphodiesterase (PDE) enzymes, especially PDE5, may serve as targets in the therapeutic treatment of DEN-induced HCC. PDE5 inhibitors, widely used as therapeutic drugs for cardiovascular diseases and erectile dysfunction, have recently been found to be promising in preclinical cancer models through the modulation of key signaling pathways implicated in the progression of tumors, such as the cGMP-PKG, JNK, and MAPK pathways. These pathways are very important for cell proliferation, apoptosis and metastasis, and their dysregulation contributes to the aggressive nature of HCC. This study assessed the potential of PDE5 inhibitors to suppress proliferation, induce apoptosis, and alter the tumor microenvironment, thus potentially improving standard chemotherapy and immunotherapy interventions. By inhibiting certain PDE isoforms with these drugs, an anticancer response might occur as part of a complex mechanism that acts on both cancer cells and the microenvironment favorable for tumor growth. A preliminary review indicated that PDE inhibitors may be a promising therapeutic approach for overcoming some of the shortcomings of current treatments, particularly the development of resistance and the toxic effects of these treatments. Additional clinical investigations are necessary to determine the safety profile, appropriate amount of Osage, and long-term efficacy of these agents in the treatment of HCC, particularly in DEN-induced animal models.
