Neurosteroids may help metyrapone reduce cocaine addiction.

This study reported that chronic use of performance-enhancing drugs significantly altered users' personalities and physical attributes, raising concerns about whether the perceived benefits outweigh the costs.

In this study, the pharmacological action of dobutamine on rabbit retinae was found to be distinct from that of other dopamine analogs like apomorphine and N-methyl-dopamine.

In this retrospective study at Toyama University Hospital, amoxapine was reported to significantly improve semen volume, sperm concentration, and total sperm count in 17 men with ejaculatory disorders, with no observed side effects over an average of 13 months of therapy.

This study provides a comprehensive analysis of anabolic-androgenic steroids, reporting that their use enhances muscle mass but is associated with significant health issues including cardiac muscle hypertrophy, liver disease, and changes in gender characteristics, emphasizing the need for patient awareness of these risks.

This review discusses the development and potential therapeutic applications of adenosine receptor agonists and positive allosteric modulators, noting that while many clinical trials have been unsuccessful, initial results for new compounds are promising.

This study reports that the metanephrine content was significantly higher in patients with alopecia areata compared to those without the condition.

In this study on male rats, parachlorophenylalanine treatment induced hypersexual behavior and hair loss linked to increased social interaction but had no effect on brain serotonin when testosterone was used instead.

This study found that manipulating neuroactive steroids during early development stages in male rats influences alcohol-induced locomotor sensitivity, suggesting their role in addiction vulnerability.

A neurosteroid can reduce caffeine-induced anxiety in rats.

This study concluded that 16β-methyl-17α-benzoyloxypregnen-4-en-3,20-dione may be a promising treatment for androgen-dependent diseases and epilepsy due to its antioxidant effects and impact on GABAergic and serotonergic metabolism in rats.

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 that AtT-20 pituitary cells with higher cAMP-dependent kinase activity had larger calcium currents and significantly increased beta-endorphin release compared to cells with lower kinase activity.

This study identified significant trends in interest around selective androgen receptor modulators, with increasing attention contrasting stagnant or declining interest in post-cycle therapies and anabolic steroids, and calls for clinicians to use social and prescription data to adjust treatment protocols accordingly.

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.

In this research, caffeine's versatile pharmacological actions were highlighted, demonstrating its stimulant, bronchodilator, diuretic, and potential anticancer effects through interactions with adenosine receptors, phosphodiesterase, and renal tubules, revealing valuable insights for drug development and therapeutic applications in medicine.

This study found that in rats, finasteride significantly reduced allopregnanolone in the cortex and increased both the rise and duration of dopamine levels in the prefrontal cortex in response to stress and anxiogenic stimuli.

This study developed and validated a highly sensitive method using ultrahigh-performance liquid chromatography with tandem mass spectrometry for accurately analyzing nine neuroactive steroids in human serum, which could enhance understanding of disease pathophysiology and support new biomarker and therapeutic discovery.

This animal study found that intravenous administration of anionic squarticles, a lipid nanoemulsion, increased survival rates in rats with amitriptyline overdose by mitigating adverse effects and restoring normal blood pressure, highlighting its potential as a detoxifying antidote.

Finasteride may cause sexual dysfunction by reducing epinephrine levels.

This article describes the synthesis of novel polyamine-modified minoxidil analogs and conjugates to potentially enhance minoxidil's biological activity, selectivity, and water solubility, but reports no new biological results.

This study found that in a rat model, 14,15-EET may alleviate central poststroke pain by enhancing thalamic inhibition through neurosteroid signaling, potentially outperforming gabapentin in early-stage treatment.

In this animal study, agmatine exhibited a protective effect against seizures related to hormone fluctuations, with results suggesting that its anticonvulsant properties may involve interactions with central neurosteroids in female rats experiencing progesterone withdrawal.

This study developed a rapid method using advanced chromatography and mass spectrometry to detect hair-growth enhancing compounds, discovering synthetic drugs in about 21% of tested supplements.

This study used micro-segmental hair analysis to identify the day of drug intake and suggested differing uptake mechanisms for co-administered drugs based on their properties.

This case study describes a severe instance of iatrogenic Cushing's syndrome induced by gamma-hydroxybutyric acid, exacerbated by combined use of betamethasone and anabolic steroids, in an HIV-positive patient on cobicistat-containing therapy.

In this study, finasteride-treated WAG/Rij rats showed a significant increase in spike-wave discharges when administered endogenous steroids THPROG and THDOC, indicating potential exacerbation of absence seizures.

This study examined 4-azasteroids using 13C-NMR spectroscopy, detailing the NMR spectrum assignments and reporting a new molecular complex of finasteride with dioxane.

In this animal study, the researchers found that administering anionic lipid nanoemulsions called squarticles increased survival rates and mitigated the adverse effects of amitriptyline overdose in rats.
