In this study, a high-fat, high-cholesterol diet in atherosclerotic mice led to skin inflammation and hair problems, which could be reversed by inhibiting glycosphingolipid synthesis.

In this study, adrenalectomy in black rats on a vitamin B-deficient diet restored hair growth and melanin deposition, effects reversed using adrenal cortical hormones.

This article discusses the role of growth hormone, insulin, and IGF-1 in acne development and highlights how diet and syndromic evidence support their involvement, but presents no new clinical findings.

This article discusses observations about the relationship between baldness and gray hair in middle-aged men, noting that baldness often precedes grayness, and suggests a possible connection to premature aging, but reports no new data.

This review discusses the role of Nutrease powder in managing hormonal disturbances in polycystic ovary syndrome and reports no new clinical results.

This paper offers a detailed overview of B vitamins, detailing their importance for energy, cognition, and metabolism, conditions leading to their deficiencies, symptoms of deficiencies, and the foods rich in these essential nutrients.

This article reviews the role of IGF-1 in acne pathogenesis and discusses how diet and smoking may influence insulin/IGF-1 signaling, but reports no new clinical results.

This study found that pigs fed a fat-free diet had significantly less body dry matter and ether extract compared to those consuming a diet with corn oil, although weight gain was unaffected by the fat content.

This study found that mice can synthesize inositol, but this ability is impaired when pantothenic acid is lacking in their diet.

This study suggests that finasteride may help alleviate high-fat diet-induced kidney damage in mice by reducing TMAO synthesis and regulating gut microbiota.

This review discusses the role of diet in managing hair loss during menopause and reports no new clinical results; it highlights the importance of nutrients like sulfur amino acids, vitamins, and minerals.

In this case study, a 12-year-old boy with a restricted diet exhibited symptoms of scurvy, including leg weakness and bruising, which improved following treatment with vitamin C and B12 supplements, highlighting the impact of severe vitamin deficiencies on health.

This review provides a comprehensive synthesis of skin aging research, highlighting the interplay of genetic and environmental factors, cellular mechanisms, and advances in diagnostic and therapeutic strategies, while also addressing current debates and future directions in the anti-aging field.

This study found that adding inositol or biotin to a pig's diet without sulfathalidine had no effect on growth or feed efficiency, but both helped alleviate deficiency symptoms caused by sulfathalidine.

This theoretical research project proposes the Carnivore Follicular Integrity Framework, suggesting that animal-based diets may support hair follicle stability through various evolutionary and mechanistic pathways.

Among young rats, this study found that a liquid protein diet significantly affects body condition but has minimal impact on gingival collagen metabolism.

This study concluded that dietary changes alter serum progesterone and estradiol levels in late gestation ewes, likely due to metabolism rather than changes in placental steroid synthesis.

This study found that mice lacking myelin protein zero-like 3 (Mpzl3) had reduced body weight and adiposity despite increased food intake, which was linked to higher energy expenditure and improved glycemic control.

This study demonstrated that allopregnanolone administration caused significant scratching in atopic dermatitis mice, and ethanol-induced scratching may be linked to increased brain allopregnanolone levels.

This study found a negative correlation between dietary monoene levels, particularly oleic acid, and the capacity for PGE₂ synthesis in rat skin, with the most severe skin issues noted in those fed Zephyr rapeseed oil.

In this research, a chemical-free herbal hair mask was formulated and evaluated in the laboratory, aiming to strengthen hair follicles, remove dirt and dandruff, and darken hair color, with the goal of treating hair problems without adverse effects associated with synthetic products.

This review discusses the interactions between skin microbiota and human skin health, examining how imbalances may contribute to skin diseases, and reports no new clinical results.

This review discusses new research on the role of retinoids in skin and hair health and reports no clinical results.

This review discusses the clinical significance of L-Lysine in treating various conditions and reports mixed findings on its effectiveness against herpes simplex virus infections, with no new experimental results presented.

This review discusses the relationship between vitamin D and various skin diseases but reports no new clinical results, emphasizing the need to assess and correct vitamin D deficiencies.

This study suggests that ovarian cycle-related progesterone and neurosteroids regulate α2-subunit expression of GABA-A receptors in the hippocampus through a pathway independent of progesterone receptors, potentially affecting brain conditions linked to the menstrual cycle.

This study found that when metabolism changes and extracellular glucose decreases, hippocampal CA3 neurons release ATP, which is converted to adenosine and reduces neuron excitability, enhancing the seizure threshold.

This study found that inhibitory neurosteroids synthesized within glial cells can reduce seizure frequency in epileptic animals by enhancing inhibitory transmission via γ-aminobutyric acid receptors.

This review discusses the role of nutraceuticals in combating skin aging but reports no new clinical results, focusing on their mechanisms of action and potential effectiveness for dermatologists.

This study found that female students experiencing diffuse hair fall had significantly lower Vitamin D3 levels compared to healthy controls.
