This study found that progesterone pretreatment in rats potentiated the effect of ethanol on mesocortical dopamine levels, suggesting an influence of neuroactive steroids on ethanol's action.

This study found that water-filtered infrared A radiation can induce the release of a model drug from gold nanoparticle-doped particles in hair follicles in an ex vivo porcine skin model, suggesting feasibility for follicular drug delivery systems.

This study reported the development of two highly sensitive ELISA assays to detect banned substances finasteride and dutasteride in human urine, offering better sensitivity than existing HPLC/MS/MS methods.

This study reports that zinc oxide or silver nanoparticles capped with vitamin A or E, incorporated into wheat gluten films, showed significant potential in promoting burn wound healing in mice by facilitating wound contraction, re-epithelialization, and collagen deposition, while also exhibiting antioxidant and antibacterial properties.

In this study, pregnenolone was found to dose-dependently reduce L-DOPA-induced dyskinesias in a rat model of Parkinson's disease, suggesting its potential as a therapeutic target for these dyskinesias.

This article discusses the widespread issue of performance-enhancing drug use in sports, its health risks, and the importance of drug testing; it reports no new study findings.

In this case study, a 55-year-old male with a history of hypospadias repair developed urinary complications due to urethral hair bezoars, and the researchers reported that transcutaneous ND:YAG laser epilation effectively removed urethral hair, preventing recurrence of such issues.

This study found that distinct neurons in the nucleus accumbens lateral shell regulate scratching behavior differently; D1R neurons promote scratching while D2R neurons help stop it, with elevated dopamine levels during chronic itch potentially enhancing persistent scratching.

This study investigated the metabolic pathways of epristeride, a new Type II 5α‐reductase inhibitor, using in vitro models and found that its metabolites show significant interactions with key proteins, suggesting implications for its role in doping control.

This research found that liposome drug delivery systems, particularly with targeted modifications, show promise for improving effectiveness and reducing toxicity in combination cancer therapies.

This study models the pathways of nandrolone and its metabolites in the body and suggests methods to counteract finasteride's role in enabling PED users to cheat drug tests.

This study found that monitoring endogenous steroid metabolites in serum may improve the detection of testosterone doping by highlighting promising biomarkers.

This study compared the echocardiographic profiles of patients with polycystic ovary syndrome to those of healthy subjects using conventional methods and tissue Doppler imaging, but it reports no specific findings here.

The study found that hybrid nanoparticles incorporating exosomes with cationic liposomes 2X3-DOPE significantly improved the delivery of both messenger RNA and small interfering RNA to rat cardiac mesenchymal stem cells in vitro, achieving up to 100% transfection efficiency for small interfering RNA.

This study found no significant difference in anagen rate improvement between the CYP-based dietary supplement and placebo in women over 60 with telogen effluvium, possibly due to variable patient inclusion related to hair growth seasonality.

Blocking CYP17A1 enzyme may help improve certain brain function issues related to dopamine.

This article discusses laboratory and physical markers that may help detect androgenic anabolic steroid abuse in athletes and reports no new primary research results.

In this study, researchers developed a nanocomposite microneedle patch containing copper/zinc dual-doped silica nanoparticles, which release substances to promote hair follicle regeneration by targeting various pathophysiological aspects of androgenic alopecia, presenting an effective anti-hair loss treatment strategy.

This study demonstrates that a newly developed nanocomposite microneedle patch, releasing copper and zinc ions along with quercetin, effectively promotes hair follicle regeneration in androgenic alopecia by targeting various pathophysiological aspects of hair loss.

This study presents a rapid method for detecting multiple xenobiotics in urine, effectively identifying 45 compounds banned in sports with detection limits below WADA's performance levels.

This study reported the development of a novel and reliable liquid chromatographic method to measure testosterone and epitestosterone in human urine, offering sensitive detection for doping control.

This review compares the CO2 and Er:YAG laser treatments for acne scars, noting that while CO2 lasers offer deeper tissue penetration for severe scars, Er:YAG lasers pose a lower risk of post-inflammatory hyperpigmentation, and recommends personalizing treatments and considering combination therapies.

In this study, researchers found that taking Saw palmetto and Pygeum africana supplements for five days altered the urinary steroid profile in a way that may interfere with the steroidal module of the Athlete Biological Passport.

This study used a zebrafish model and advanced mass spectrometry to identify 11 metabolites of epristeride, revealing significant effects on purine metabolism and aromatic amino acid biosynthesis, which may aid in developing anti-doping detection methods.

This study found variation in erythema induction across skin types, suggesting different SSR dose responses and highlighting a potential model for tailoring anti-inflammatory treatments.

In this study, researchers found that during late pregnancy, neuroactive steroid fluctuations increase the number of extrasynaptic GABAA receptors in rat hippocampal cells.

This review discusses the neurobiology of sexual function and reports no new results; the authors cover multiple endocrine and neurotransmitter influences on sexual desire, arousal, and orgasm stages.
