This study found that sebaceous glands predominantly exhibit oxidative activity of the type 2 17β-hydroxysteroid dehydrogenase isozyme, which is not inhibited by 13-cis retinoic acid.

This review discusses the association between oxidative stress and alopecia areata while proposing antioxidants as a potential supplementary therapy, but it reports no new clinical results.

In this study, ELE was found to protect against oxidative stress-induced testosterone reduction in TM3 Leydig cells by increasing testosterone synthesis and decreasing its conversion.

This study investigated the tensile response and morphological changes of different ethnic hair types using AFM, showing variations between virgin, chemically damaged, and conditioner-treated Caucasian hair under different conditions.

In this study, transgenic male mice over-expressing the androgen receptor in mesenchymal stem cells showed reduced fat mass and improved glucose clearance, suggesting enhanced androgen sensitivity may alter body composition.

This study found that various petroleum distillates caused significant skin changes in mice, with severity varying based on the product and penetration pathway, potentially leading to skin tumors through non-genotoxic mechanisms in longer-term exposure.

This study found that Annurca apple polyphenolic extracts reprogram hair follicle metabolism in mice, enhancing mitochondrial activity and keratin production while inhibiting some metabolic pathways.

This study found that in male rats, hesperidin co-administration ameliorated finasteride-induced testicular toxicity by reducing oxidative stress and improving antioxidant status, sperm parameters, and enzyme activity compared to finasteride treatment alone.

This study concluded that an 8-week low-starch/low-dairy diet increased fat oxidation in overweight and obese women with PCOS.

This study visualized mitochondrial metabolism in cultured bovine hair follicles and plucked human hairs, finding that ROS and mitochondrial polarization correlate in specific hair follicle regions, particularly near keratin deposition sites.

This study found that Wet-type Age-Related Macular Degeneration patients had higher oxidative stress and HMGB-1 levels compared to healthy controls, suggesting a link to increased tissue inflammation and necrosis.

This study found that combining microfocused ultrasound with autologous blood cell factors significantly improved skin rejuvenation compared to using microfocused ultrasound alone.

This review discusses recent research on the relationship between gut microflora and depression, highlighting the potential for new insights into the pathogenesis and treatment of major depressive disorder.

This study found that therapy significantly reduced serum IgM levels in dogs with severe dermatitis, but not in those with mild dermatitis, highlighting the effect of treatment on immune response in severe cases.

In this study, researchers found that chemical treatments like bleaching can cause severe damage to the hair cuticle, with previously modified hair showing complete deterioration compared to the partial degradation seen in virgin hair, highlighting the need for mindful cosmetic practices.

This study observed that the COVID-19 pandemic altered the distribution of dermatological diseases, with increased cases of conditions like scabies and telogen effluvium, while acne and psoriasis cases decreased.

This study found that Wistar rats fed with grass extracts from mining areas accumulated trace metals, particularly in the spleen, leading to organ pathology and signs of toxicity.

This review discusses the nutritional and therapeutic benefits of honey based on its botanical origin, and it reports no new clinical results, instead calling attention to its varied uses and potential health impacts.

This review discusses age-related and environmental factors affecting scalp hair changes in women, highlighting diagnostic complexities and ongoing research into targeted treatments, without reporting new clinical results.

This study reports that polyphenols from Annurca apples may safely promote hair growth and protect against chemotherapy-induced alopecia without interfering with chemotherapy regimens.

This study observed that the Aptamin C® and vitamin C complex had effective ROS-scavenging and anti-inflammatory effects on human skin in both in vitro and clinical tests.

This study found that permanent waving treatment induces structural changes in the cortex proteins of white human hair, significantly reducing its tensile strength without altering the S-S band intensity.

This study found that autophagy plays a role in sebaceous gland function and sebum composition control in mice lacking the Atg7 gene in keratinocytes.

This study found that inhibiting AP1 transcription factor activity in the suprabasal epidermis of mice alters keratinocyte gene expression, reducing barrier integrity and mimicking human keratoderma.

This article reviews the skin and hair changes associated with menopause due to hormonal shifts and reports no new clinical results.

This pilot study found that hair metabolome analysis may help differentiate pregnancy complications from healthy pregnancies by revealing significant metabolite differences between trimesters.

This study found that dietary supplementation with collagen, chondroitin sulfate, low-molecular weight hyaluronic acid, Pycnogenol®, and coenzyme Q10 significantly improved skin hydration, elasticity, nail hardness, and hair condition in patients with age-related dermatological changes after 12 weeks.

This source critically examines Bruce Ames's influential contributions to biochemistry, particularly his theories on oxidative stress and mitochondrial DNA damage in aging, while acknowledging current challenges to his work and highlighting his lasting impact on the fields of mutagen screening and public health.

This study reports that in a rat model of myocardial infarction, Zn-Cu ion sequential therapy improved cardiac function and cardiomyocyte metabolic activity by precisely regulating ion concentrations and maintaining elevated levels of the Per2 protein, important for cellular repair.

This study suggests that IL-33 promotes hair follicle changes and T cell infiltration in psoriatic mice and humans, contributing to psoriatic alopecia.
