This study found distinct hair metal profiles in Parkinson's disease patients, with lower iron and copper, higher manganese and arsenic, and explored their link to gut dysfunction and microbiota dysbiosis, suggesting hair metal analysis as a promising diagnostic tool.

This study found that decreased allopregnanolone levels through inhibition or intrauterine growth restriction in guinea pigs were linked to altered brain development markers, suggesting a role for neurosteroids in fetal brain protection and development.

This study concluded that male mice are more susceptible to valproic acid-induced autism spectrum disorder than female mice, with noticeable differences in brain histoarchitecture and receptor protein levels.

Stress can cause hair loss and skin issues by affecting hair growth cycles.

This paper reviews existing studies on the role of environmental humidity in skin health, highlighting that low humidity can impair the skin's barrier function and trigger inflammatory responses, though the precise mechanisms remain to be fully explored.

This study reported that supplementing rat hair follicle stem cells with chick embryo extract enhanced their migration and proliferation, possibly promoting differentiation toward Schwann cells.

This study found that progesterone and its metabolite, allopregnanolone, provided anti-anxiety and anti-depressive effects in female mice, potentially independent of nuclear progestin receptors but requiring 5α-reduction and estradiol's influence on brain-derived neurotrophic factor.

This study found that early postnatal androgen activity affects the long-term expression of hormone receptors differently in female Wistar rats, influencing neural system programming during development.

This study suggests that post-finasteride syndrome and post-SSRI sexual dysfunction share potential etiopathogenetic mechanisms involving brain modulators, neurotransmitters, and gut microbiota, although more research is needed to understand these conditions fully.

This study found that Cerasus serrulata extracts, when obtained through specific methods, demonstrate significant antioxidative and antibacterial properties, as well as potential anti-alopecia effects in a mouse model, potentially making them useful supplements for these purposes.

This study found that injecting hepatocyte growth factor-enhanced hair follicle stem cells into a rat model of ischemic stroke improved recovery by reducing inflammation, protecting the blood-brain barrier, and promoting angiogenesis.

This literature review on neurocosmetics found that both nature-derived peptides and synthetic molecules can improve skin concerns like aging and pigmentation, while also promoting emotional well-being; however, gaps in long-term efficacy and personalized approaches remain.

This preclinical study found that finasteride withdrawal in rats caused inflammation in the gut and hypothalamus, while allopregnanolone treatment partially reduced these effects, suggesting potential therapeutic benefits for post-finasteride syndrome.

In this study, researchers observed that heat stress significantly affected hair and skin traits in two indigenous goat breeds, with Kodi Aadu goats demonstrating greater thermal resilience compared to Kanni Aadu goats, potentially due to differences in gene expression and methylation.

This study reported that rice bran oil from the Thai rice variety BB4CMU showed potential in promoting melanin production and inhibiting steroid 5α-reductase, suggesting a natural option for hair revitalization.

This study found that ethanolic extracts of Buebang 3 CMU may promote hair growth and prevent hair loss more effectively than minoxidil by enhancing bioactive compounds and activating key signaling pathways.

This study reports that Hair RiseTM microemulsion, made from plant extracts, significantly enhanced hair follicle cell growth and improved hair growth signaling pathways, suggesting it as a plant-based alternative for androgenetic alopecia treatment.

Environmental factors like temperature and nutrition affect hair growth, with humans showing seasonal hair growth differences.

Food deprivation increases MST enzyme in the brain, possibly affecting energy balance.

This study focused on the rheology of almond oil at various temperatures and shear rates, using a Brookfield RVDV II I Ultra Rheometer, to evaluate its potential as a biodegradable lubricant.

In this animal study, atorvastatin co-administered with trastuzumab reversed trastuzumab-induced cognitive impairment (chemo-brain) and improved its anti-cancer efficacy without causing hair loss.

In this study, remote photobiomodulation therapy to the lungs improved behavioral and neurological outcomes in rats with repeated closed-head injuries, suggesting potential preventive benefits for brain health.

This study found that cocaine disrupted the relationship between certain brain androgen levels and sexual behavior in male rats, with dose-dependent effects on testosterone metabolism.

This article discusses the role of hyperarousal and brain activity in insomnia and its potential link to sleep disturbances in depression, but it reports no new empirical findings.

This source reports that clinical trials using advanced Deep Brain Stimulation systems, augmented with AI to integrate kinematic data, eye tracking, and cognitive assessments, show promise in improving diagnostic accuracy and monitoring symptoms for patients with Parkinson's disease.

In this study, male-derived brain tissue exhibited higher cell death following ischemia compared to female-derived tissue, and certain steroid hormones showed different neuroprotective effects depending on the sex of the tissue.

This study found that storing horse hair follicles in RNAlater® at cool or room temperature for up to a week did not affect RNA integrity, suggesting it allows for flexible sample transport without immediate freezing.

This study found that using SH-SY5Y cell lysate in Western blot analysis may improve the diagnosis of Satoyoshi syndrome by providing more consistent and clear immunoreactive band patterns compared to brain homogenate, potentially leading to earlier diagnosis and treatment.

This study suggests that apoE4 may contribute to cognitive decline by reducing androgen receptor levels in the brain, but androgen treatment improved memory deficits in female mice expressing human apoE4.

This study observed that dietary intake of glucoraphanin during juvenile and adolescent stages prevented cognitive deficits and abnormal gene expressions in the brain of adult offspring exposed to maternal immune activation, potentially implicating centrosome-related genes in the development of psychosis.
