This study investigates the stress response of blood donors at three different donation moments by analyzing cortisol and cortisone levels in oral fluid samples. To simultaneously detect these analytes, we developed and validated a new highly sensitive method using high-performance liquid chromatography coupled to a triple quadrupole mass spectrometer (HPLC-MS/MS). Glucocorticoid hormones were found in all samples with cortisone exhibiting higher concentrations than cortisol. Statistical results revealed a weakly negative trend over time for both analytes levels, indicating that the most crucial donation moment is upon donors’ arrival. A notable distinction was found in the evolution of the glucocorticoid hormones in different locations, suggesting that different environmental factors influence stress level more than the act of donation itself.</div></div>","PeriodicalId":21997,"journal":{"name":"Steroids","volume":"217 ","pages":"Article 109604"},"PeriodicalIF":2.1,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143734753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These receptors, along with their genetic variations, have been linked to various human health conditions. They are activated by an array of substances, including hormones, nutrients, and toxins, indicating their involvement in numerous biological processes. Specifically, in males, TRs are notably present in the testes and epididymis, where they contribute to the hormonal production, spermatogenesis, and sperm maturation. In females, these receptors are found in the ovaries, uterus, and myometrium, playing crucial roles in ovulation, menstrual cycle regulation, and embryo implantation. There are a lot of missed areas regarding TRs research that imposes to fulfill the gaps in the current understanding of their role in reproduction. This review aims to provide a comprehensive overview of the emerging roles of extraoral TRs in reproductive health, highlighting their physiological and pathophysiological significance in various reproductive processes.

However, overactivation of this process can be detrimental to the point of fatality. To overcome this overactivation, immunosuppressant agents such as steroids and non-steroidal anti-inflammatory drugs (NSAIDs) are used. Given the limitations of these drugs, including their side effects, an urgent need for development of potent and safer anti-inflammatory drugs is evident. Diosgenin, a steroidal saponin (a glycoside found in plants) and its analog, BSS-4 are gaining ground in this respect. Our objective in this study was to determine the effectiveness of BSS-4 in an established model of inflammation and provide clues on its mechanism of action. Carrageenan (Carr)-induced paw edema was used to evaluate the effectiveness of two doses of BSS-4 (0.5 and 1 mg/kg administered intraperitoneally) in adult male Wistar rats. Plantar edema was induced by subcutaneous injection of 50 µL of carrageenan (1 %) into the plantar aponeurosis of the right paw. Inflammatory cytokine markers, tumor necrosis factor-alpha (TNF-α), and interleukin-1 beta (IL-1β) were quantified in this paw region using immunohistochemical assays. BSS-4 at 0.5 mg/kg dose, significantly reduced the paw edema up to three hours after administration. Concomitantly, TNF-α and IL-1β immunostaining were significantly reduced. BSS-4 also preserved the tissue architecture as assessed by hematoxylin and eosin (H&E) staining.

However, their prolonged use often leads to severe side effects such as osteoporosis, hypertension, cardiovascular, gastrointestinal complications, etc. To search for potential and safer therapeutic options, the present study aims to explore the potency and drug-ability profiles of anti-inflammatory phytosteroids (PSs). In a target-specific approach, we have selected three key molecular targets: glucocorticoid receptor/GR (PDB ID: 4P6W), cyclooxygenase-2/COX2 (PDB ID: 5F1A), and inducible nitric oxide synthase/iNOS (PDB ID: 4NOS) for a docking study of 167) selected PSs. The drug-chemistry profiles (physicochemical, toxicity, pharmacokinetic, drug-ability, etc.) of PSs were also assessed using various bioinformatics and chemoinformatics tools. The above assessment suggested that withaminilide B (PS46) is a lead candidate with higher drug-ability properties. Further, the drug stability and kinetic behaviour of the lead with the GR target ‘GR-withaminilide B’ in comparison with the control drug, ‘GR-triamcinolone acetonide’ docking complex, were studied through molecular dynamics (MD) simulation at 200 nanosecond with free energy calculation (MM/PBSA). Overall findings suggested that PSs exhibit distinct drug-ability profiles based on their functional attachments with a steroidal core moiety, where withaminilide B is a lead PSs among all to be used as alternative/ complementary candidates expected with limited adverse effects. Further experimentation is essential before mainstream application, but the study provided a platform to select drug-able candidates with a higher chance of experimental success and accelerate the drug discovery process within limited resources.</div></div>","PeriodicalId":21997,"journal":{"name":"Steroids","volume":"217 ","pages":"Article 109601"},"PeriodicalIF":2.1,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143693394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
