Lowering 3α,5α-THP in the hippocampus increases anxiety and depression in proestrous rats.

In this animal study, finasteride significantly improved autism-like symptoms in rats by reversing biochemical markers and enhancing behaviors, potentially due to its antioxidant and anti-androgen effects.

This study found that patients with telogen effluvium who delayed hair washing or collected shed hair were more likely to have higher clinical severity and increased disease-related economic burdens, suggesting these behaviors can aid clinical assessments.

This study found that progesterone implantation in castrated male rats mitigated stress-induced increases in corticosterone levels and protected against spatial memory impairment and increased exploratory behavior.

In this study, chronic finasteride administration in male rats led to depression- and anxiety-like behaviors only in specific tests and moderately affected hippocampal synaptic plasticity, possibly due to adaptive plasma corticosterone level changes over time.

In this study, researchers examined the genetic factors impacting cortisol and DHEA concentrations in the hair of healthy pigs; they found that cortisol levels were heritable and genetically correlated with behavioral stress responses, suggesting these hormones could potentially serve as indicators for selecting disease-resilient pigs.

This study reveals that somatosensory neurons in mouse skin exhibit structural plasticity during hair-follicle regeneration, which may temporarily impair the reliability of encoding gentle touch.

This descriptive abstract provides information about a continuing medical education activity for physicians, designating 1.5 credits for participation, but reports no new research findings.

This study examined children with trichotillomania using a set of specific questions to better understand the condition and aid clinicians who may be unfamiliar with it.

In this study, withdrawal from progesterone and treatment with finasteride were associated with increased signs of depression-like behavior in female mice, suggesting decreased allopregnanolone levels may play a role.

The study created a test that found hormonal and toxic effects in plant and fungal extracts using prostate cancer cells.

This study found that a traction alopecia prevention program for middle school students increased awareness and understanding of TA, but converting this awareness into changes in hairstyling habits proved challenging, highlighting the need for culturally sensitive strategies to influence behavior in at-risk communities.

This study introduces a new test using a pendulum device to assess the bending stiffness of hair fibers, which can evaluate the effects of different hair treatments.

This study found that human hair fibers significantly improve the shear behavior of dry sand, but under saturated conditions, the reinforcement sustains shear strength similar to unreinforced sand.

This case report describes a patient with primary cutaneous natural killer/T-cell lymphoma, nasal type, where monoclonal Epstein–Barr virus genome expansion was associated with terminal aggressive behavior after an indolent clinical course.

This case report describes a Russian wolfhound's aggression being linked to hypothyroidism, which was successfully managed with levothyroxine therapy.

Adjusting hair dryer settings improves drying efficiency and keeps hair healthy.

In this study, progesterone showed anticonvulsant effects in mice via a mechanism that is at least partially independent of its metabolism to THP, without significant psychotoxicity.

Olanzapine reduces stress-related anxiety in rats when given acutely.

In this study, adult male rats exhibited significant anxiety-like behaviors following finasteride withdrawal, including pronounced hyperactivity and novelty avoidance, highlighting potential parallels with post-finasteride syndrome observed in clinical settings.

This study suggests that the neurosteroid allopregnanolone contributes to stress resistance in mice, and the ALLO mimetic drug alfaxalone may offer anxiolytic benefits without muscle-relaxant effects.

Finasteride improved reflexes and motor activity in rats with liver-related brain issues.

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.

In this animal study, the methanolic extract of Crataeva nurvala leaves was found to possess sedative and anxiolytic properties, potentially linked to GABAergic activity and certain neuroactive compounds.

This study reports that soy protein isolate/hydroxyethyl cellulose nanofibrous mats embedded with diclofenac sodium and halloysite nanotubes demonstrated sustained drug release, effective antibacterial action against E. coli and B. subtilis, and maintained biocompatibility, highlighting their potential use in wound care.

This study found that 3alpha-diol, an androgen metabolite, improved cognitive and affective performance in aged male rats, suggesting its role in countering age-related decline in hippocampally-influenced behaviors.

This study found that D-004, a lipid extract from royal palm fruit, has a moderate antidepressant effect in mice, which may help treat depressive symptoms in patients with benign prostatic hyperplasia.

This study found that rhesus macaques with inhibited or anxious temperaments had less alopecia, suggesting temperament may influence hair loss in these animals.

In this study, researchers observed that chronic stress affected wild-derived house mice differently by sex, with females showing less weight gain and distinct behavioral changes, while males exhibited higher hair corticosterone levels, suggesting divergent coping strategies and implications for sex-specific stress assessment protocols.

This article reviews common hair disorders and their normal anatomy and life cycle, but reports no new research findings.
