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.

This study found that both finasteride and dutasteride significantly reduced L-DOPA-induced dyskinesia in a rat model of Parkinson's disease, with dutasteride showing greater effectiveness at lower doses.

This study found that in rodent models, the ability of D1 dopamine receptor activation to impair sensory gating is facilitated by 5α-reductase type 1, which produces allopregnanolone.

This study suggests that the 5α-reductase inhibitor finasteride modulates sensorimotor gating in rats by affecting D1 and D3 receptors, but not D2 receptors, with varying effects based on genetic strain.

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.

Finasteride reduces certain behaviors caused by D1-like receptor agonists but not by D2-like receptor agonists in mice.

This study found that dopamine directly induces the catagen phase in human scalp hair follicles in vitro.

This study found that male 5α-reductase 2 knockout mice showed deficits in social dominance behaviors and reduced dopamine receptor binding in a brain region related to social ranking.

This article discusses the potential of using human hair follicles as a model to study prolactin's regulation and activities but reports no new experimental findings; the authors suggest further research in this area.

Using too much minoxidil foam can cause a rare movement disorder with facial twitching, but symptoms go away when the correct dose is used.

This study examines the pathogenetic role of hormonal imbalances in chronic prostatitis, highlighting that decreased androgens and increased estrogens contribute to prostate inflammation and impaired spermatogenesis, and explores hormonal therapies' potential for restoring reproductive function.

This study examined the effects of finasteride on human Leydig cells and found altered methylation in dopaminergic pathways, suggesting potential epigenetic contributions to post-finasteride syndrome, warranting further investigation.

This study found that early life stress significantly affects hedonic sensitivity to high-palatable food by altering gonadal hormones in prenatally-stressed male and female rats, with sex-dependent changes in reward-related behaviors and neurochemistry.

This study found that dutasteride may offer neuroprotection in early-stage Parkinson's disease by preventing loss of striatal dopamine and altering steroid levels in MPTP-lesioned mice.

This study suggests that the neurosteroid allopregnanolone may play a crucial role in how ethanol affects neurons related to alcohol addiction vulnerability.

Finasteride may cause sexual dysfunction by reducing epinephrine levels.

This case report describes reversible hair loss in a patient taking aripiprazole, suggesting this side effect may be common among psychotropic medications.

This study found that finasteride significantly reduced levodopa-induced dyskinesia in both male and female rats without diminishing l-DOPA's motor benefits, indicating potential for clinical trials in Parkinson's patients.

Isolation stress in rats reduces brain enzyme levels, affecting dopamine function.

This study identifies substance P, TNFα, and IFNγ as novel regulators of prolactin and its receptor expression in human skin, suggesting intracutaneous prolactin is not controlled by dopamine.

In this study, researchers developed a novel method combining in silico and in vitro techniques to discover Aromoline, a potential osteoarthritis treatment that increases type II collagen expression in chondrocytes by targeting the dopamine receptor D4.

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

This study found that systemic administration of NDP-MSH, a melanocortin receptor agonist, provided neuroprotective effects on dopaminergic nigrostriatal neurons in a mouse model of Parkinson's disease, reducing neuroinflammation and suggesting a role for regulatory T cells in these neuroprotective effects.

In this study, finasteride altered the expression of nine proteins in the rat nucleus accumbens, suggesting new therapeutic targets and mechanisms for its effects on neuropsychiatric conditions.

This study suggests that altering levels of the neurosteroid allopregnanolone during neonatal stages in rats may impact alcohol consumption and dopamine release in adulthood, indicating potential effects on alcohol reward properties.

This report highlights a case where a woman's use of the dopamine agonist pramipexole for Parkinson's disease was associated with hair loss, which improved after discontinuing the drug.

This review explores potential indications for prolactin receptor inhibitors beyond breast and prostate cancers, emphasizing the need for potent antibodies to further research prolactin receptor expression.

In this randomized study, BAY 1158061, a prolactin receptor antibody, was found to be safe, well-tolerated, and exhibited low immunogenicity in healthy postmenopausal women, but had no effect on serum prolactin levels compared to placebo.

Finger length ratios are not linked to the number of specific gene repeats affecting testosterone sensitivity.
