This study found that administering an alcoholic extract of Mentha spicata leaves significantly reduced testosterone levels and aggressive behavior in female rats with elevated testosterone, suggesting its potential protective role against such symptoms.

This study reported that certain minoxidil conjugates, specifically those with spermine, methylenedianiline, and diaminofluorene, were able to induce differentiation in HL-60 acute myeloid leukemia cells without toxicity at a concentration of 10 μM.

This study found that subcutaneous injections of guanethidine or 6-hydroxydopamine induced premature hair growth in mice, suggesting a role for sympathetic nerves in hair growth control.

This article responds to "The Assessment and Treatment of Geezers" by highlighting that some individuals protest against perceived self-importance and verbosity despite fitting the geezer definition.

This study found that in rats, morphine exposure may increase 5alpha-reductase activity in the CNS, leading to decreased testosterone levels, an effect blocked by finasteride.

This study found that the estrous cycle influences the effect of the δ-GABAAR agonist THIP in reducing binge drinking behavior in female mice, with receptor expression elevated during diestrus.

This study suggests that neurosteroids and compounds acting on GABA(A) receptors, like THIP, may modulate ethanol intake by influencing drinking patterns.

This review discusses adverse reactions to antihelminthic drugs and highlights that levamisole, a common street cocaine adulterant, can cause serious side effects, including skin necrosis and vasculitis.

This study found that methanol extract of Mimosa pudica showed dose-dependent sedative effects in mice, suggesting its potential for developing new sedative and anti-anxiety medications.

This study found that MENT is 10 times more potent than testosterone in suppressing gonadotropins and contributing to anabolism in monkeys, with a potentially wider therapeutic index for human androgen replacement and male contraception.

This case report describes a 52-year-old woman who developed retiform purpura after using cocaine likely adulterated with levamisole, highlighting the need for levamisole detection in such cases.

This case report details a fixed-drug eruption in a woman linked to the use of dextromethorphan, marking it as a previously unreported skin reaction to this medication.

This study using high-performance liquid chromatography reported that mice with more diverse gut microbiota had higher levels of specific compounds in hair compared to those with less diversity, with stress affecting certain plasma levels.

This study underscores the use of hair analysis in forensic toxicology, highlighting its ability to detect drugs such as opioids and amphetamines, while noting limitations related to hair growth cycles, result interpretation, and cost of techniques.

This study found that methotrexate treatment for 15 days suppressed tuberculin hypersensitivity in Strain 2 guinea pigs without causing lymphopenic or anti-inflammatory effects.

A neurosteroid can reduce caffeine-induced anxiety in rats.

This review highlights the various nonmedical uses of anabolic androgenic steroids and associated polypharmacy, suggesting that preventing their abuse should be a public health priority, but it reports no new findings.

This research suggests that fluoxymesterone, an anabolic steroid, may inhibit a key enzyme, potentially contributing to cardiovascular issues by affecting cortisol's activation of mineralocorticoid receptors.

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 collection from the 2021 Manfred Donike Workshop outlines advancements in doping detection, highlighting new test methods and challenges, with a focus on steroidal substances, peptide hormones, and gene doping analysis.

This study found that early diagnosis using gas chromatography/mass spectrometry and appropriate long-term treatment are crucial for improving outcomes in patients with methylmalonic acidemia.

In this study, 4‐MAPC treatment reduced ventral prostate weight in rats primarily through decreased synthetic activity, with testosterone propionate increasing prostate weight and activity at pharmacologic doses.

This article reports that cocaine injections can lead to skin lesions containing talc crystals at the sites of injection.

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.

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.

This study developed a sensitive and specific method for detecting testosterone in horse hair, finding trace amounts in samples for up to five months after administering a single dose.

This study confirmed that methimazole use is associated with agranulocytosis, pyrexia, exposure during pregnancy, and hyperthyroidism, while also identifying new safety signals like premature birth and septic shock that require further investigation.

This study found that a methanolic extract of Sterculia foetida seeds demonstrated significant thrombolytic, anti-arthritic, analgesic, and antipyretic activities, with moderate cytotoxic effects in vitro and in vivo.
