This study found that bariatric surgery effectively treated morbid obesity and improved quality of life and the resolution of comorbidities for most patients.

This review found that many low-level light therapy studies report beneficial effects but often fail to provide adequate measurement details, affecting the reliability and repeatability of the research.

In this study, researchers found that Asian hair contains more integral lipids than European or African hair, which may protect it better from UV-induced damage.

This study found that activating Nrf2 in human hair follicles significantly reduced oxidative stress, lipid peroxidation, and protected against hair growth inhibition, suggesting a protective role for Nrf2 against redox insult in this context.

In this study, hydroxychloroquine use was associated with a delayed onset of integument damage in SLE patients, while higher disease activity over time predicted quicker damage development.

This study found that the vitamin D receptor is crucial for initiating the postnatal hair follicular cycle in mice, preventing alopecia associated with its inactivation.

This study found that oxidative damage is present in the mitochondria of PolG mice, which exhibit premature aging-like phenotypes due to mitochondrial dysfunction.

This study suggests that melatonin may have a radioprotective role against X-ray-induced skin damage in rats, as evidenced by milder injury markers in pretreated animals.

Human hair keratin genes hHa2 and hHb1 are located on chromosomes 17 and 12.

This study concluded that an endogenous circannual rhythm of prolactin secretion in mouflon influences their seasonal hair growth and moulting cycle, which varies under different photoperiodic and melatonin treatments.

This review discusses the various roles of vitamin D in skin disorders, including established use in psoriasis and potential applications for atopic dermatitis and skin cancer prevention, but reports no new clinical results.

In this review, researchers explored the roles of vitamins A, B3, C, D, and E in skin immunity, highlighting their potential as therapeutics for skin diseases due to their antioxidant, anti-inflammatory, and antimicrobial properties.

This study identified 43 compounds in Platycladi Cacumen, including flavonoids, and found significant chemical variation in flavonoid content across different regions and processed products.

This study observed that DNA damage response (DDR) plays a key role in pressure overload-induced cardiomyocyte hypertrophy, with disruption of the ATM kinase pathway potentially modulating this hypertrophy in mice.

This report describes two cases of sustained hair repigmentation related to porphyria cutanea tarda, though the underlying mechanism remains unclear.

This study found that while genetic variants contribute minimally to predicting hair greying in a Polish population, age remains the primary predictor, underscoring the complexity of hair greying as a genetic trait.

This study discusses the potential association between low vitamin D levels and insulin resistance, suggesting that vitamin D deficiency may contribute to disorders like obesity and diabetes, but emphasizes the need for further research to confirm these links.

This study found that using a hair dryer at 15 cm with continuous motion causes less surface damage to hair compared to natural drying, although higher temperatures increased overall surface damage.

This study found that ultraviolet radiation negatively affects hair follicle functions in human scalp skin, and caffeine application may provide some protective effects against this damage.

In this study, hair bleaching with ammonium persulfate and hydrogen peroxide caused significant damage to hair structure and severe skin reactions in rats, highlighting the need for cautious bleaching procedures.

This study found that androgen/androgen receptor signaling accelerates premature senescence in dermal papilla cells, highlighting a potential target for treating androgenetic alopecia.

This study found that extensive cuticle damage from diperisophthalic acid oxidation did not alter the tensile properties of human hair, suggesting that these properties are mainly due to the cortex rather than the cuticle.

This study provides evidence-based recommendations for the off-label use of topical vitamin D in treating certain skin conditions, but highlights the need for higher quality studies for further validation.

This study developed an objective standard grading system for evaluating hair damage using scanning and transmission electron microscopy.

This study found that radiofrequency radiation from mobile phone use may increase DNA damage in hair follicle cells of the ear canal, with greater exposure duration linked to higher damage levels.

This study reports that hair damage from bleaching is associated with the oxidative cleavage of fatty acid thioester bonds, detectable by measuring the decrease in mass spectrometry peak at m / z 76.

In this study, mutations in the vitamin D receptor were identified in Brazilian children with rickets and alopecia, leading to impaired receptor activation and reduced 24-hydroxylase expression.

This study suggests that impaired VDR signaling in mice leads to dysregulated Ddit4 expression, impacting hair cycle progression and wound healing.

In this study, antioxidant vitamins A, C, and E were found to help protect against intestinal damage caused by radiation in rats, with vitamin E being the most effective.

This study found that the small molecule honokiol may protect against inflammation, collagen breakdown, and cell damage caused by cigarette smoke in skin cells cultured in vitro.
