This study found that a solution containing 0.5% Camellia japonica placenta extract increased scalp moisture and reduced sebum content, dead keratin, and erythema in adult females, suggesting potential as a scalp treatment.

In this review, several studies on Astragalus species, particularly Astragalus membranaceus, highlight their skin rejuvenating, photoprotective, antimicrobial, and wound-healing properties, though the authors note limitations due to reliance on non-human studies and short trial durations.

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 found that glycosaminoglycan levels were higher in the occipital area of the hair shaft compared to the parietal area, with children showing higher levels than adults.

In this study, higher expression levels of aromatase and steroidogenic acute regulatory protein were correlated with increased estrogen synthesis and fewer hair follicles in human skin, suggesting a link to elastic fiber formation and hair growth.

This study found that elevated carbon dioxide levels may help mitigate water deficit stress in soybean roots by altering gene expression related to stress and nutrient transport.

This study observed that hair follicles in hair loss patients had increased levels of Propionibacterium acnes, potentially linked to elevated immune response gene expression in miniaturized hair follicles.

This case report illustrates the risk of skin necrosis in patients with high antiphospholipid antibody levels after stopping anticoagulation therapy, highlighting the necessity for careful monitoring.

This study found that a new hybrid polymer containing hydrolyzed protein and silicone effectively improved moisture feel and prevented discoloration in dyed hair, particularly benefiting damaged hair.

This study found that under optimized extraction conditions, the Gleditschia fera fruit extract contained a high level of saponins and demonstrated notable antioxidant activity.

This study found that combining shikimic acid with Prunus mume fruit extract significantly reduces type I 5α-reductase levels in testosterone-stressed skin sebocytes, surpassing the effects of shikimic acid or standard acne treatments alone, and shows promise for stable, non-irritating acne remedies in cosmetic formulations.

In this animal study, researchers found that exposure to a CO2 laser at various power levels caused significant skin damage in rats, including severe burns, coagulation, and tissue obliteration, with higher laser doses resulting in more pronounced injuries.

This study found that acupressure on specific points improved health-related quality of life and reduced total testosterone levels and clinical symptoms in patients with polycystic ovary syndrome compared to controls.

In this study on diabetic mice, researchers demonstrated that onion extract significantly lowered blood glucose levels at doses of 500mg/kg and 1,000mg/kg, showing comparable effectiveness to the diabetes medication metformin.

This study found that hair analysis is an effective non-invasive method for assessing metabolic fluctuations, showing stable advanced glycation end products levels that correlate with age and differ significantly between diabetic and non-diabetic rats.

This study found that glycine treatment inhibited melanogenesis in B16F0 melanoma cells and reduced melanin content in C57BL/6J mice by down-regulating tyrosinase protein levels.

This study developed a reliable RP-HPLC-DAD method, finding that amino acid concentrations in bleached hair decrease with higher hydrogen peroxide levels, notably affecting cystine.

This study investigated the effects of ethanol leaf extracts from Ziziphus jujuba and Eclipta alba on cognitive impairments in diabetic rats, finding significant improvements in learning and memory with these treatments, along with decreased blood glucose levels over 21 days.

This retrospective cross-section study found that in a cohort of Pica patients in Iraq, 92.4% were female, and many had low levels of ferritin, hemoglobin, and vitamin D, which may contribute to the disorder by causing psychological issues.

This narrative review summarizes evidence on NAD⁺ biosynthesis and turnover, highlighting that while NAD⁺ precursors like NR and NMN consistently boost NAD⁺ levels in preclinical and human studies, clinical outcome results remain varied, indicating a need for more standardized human trials.

In this study, different drying methods for Hedychium spicatum rhizomes significantly affected the essential oil yield, antioxidant potential, and compound composition, with the HSOV30 method yielding the highest oil content, antioxidant activity, and specific compound levels such as 1,8-cineole and elemol.

This study indicates that hair analyses for calcium and phosphorus are unlikely to be useful for assessing the nutritional status of horses, suggesting soil and feed analyses as more effective alternatives.

This study found that hair fibers broke down and lost keratin in extremely basic conditions, revealing the inner medulla and changing the color of the fibers.

This study found that hair cortisol levels in black-tailed prairie dogs, influenced by factors like predation risk and lactation, were associated with reproductive success, supporting the Cort-Adaptation hypothesis.

This study found that sows consuming beet pulp had higher feed intake and improved litter performance during heat stress, while a high-fiber diet enhanced insulin levels, suggesting dietary fiber's importance for reproductive and metabolic health in sows.

This study observed that among individuals with scalp seborrhoea, the scalp showed higher sebum levels, lower hydration, and compromised barrier function compared to other areas, and that a single shampoo application containing piroctone olamine significantly reduced sebum and oxidative stress markers.

This study observed that in young women, the scalp microbiota is influenced by sebum level, barrier sensitivity, and lifestyle factors, with barrier sensitivity emerging as a key factor, offering insights for further research into scalp health and conditions.

This study found that in vitro heat straightening of hair reduced THC and cocaine concentrations but increased CBN and BZE levels, suggesting heat conversion of these substances.

This review examined the pathological effects of mechanical pressure on human skin at the cellular level, highlighting how various skin cell types respond to pressure, potentially leading to pathological changes such as inflammation, ischemia, and impaired differentiation.

In this study, researchers observed that Malassezia species show different lipid metabolism and growth patterns depending on pH, with slightly acidic conditions promoting beneficial lipid bio-conversion for skin health, while neutral pH resulted in lower growth and lipid content, potentially negatively impacting the skin.
