This study used atomic force microscopy to identify significant morphological differences in hair from patients with lichen planopilaris compared to healthy controls, noting more scratches, uneven edges, and pitted scales in affected hair, which may aid future research on the condition.

This study found that ultraviolet A rays damage all hair types, with stronger adverse effects on colored and permanently waved hair, suggesting the use of sunblock products for hair protection.

This study found that rare damaging variants in the KRT82 gene, which affect hair shaft integrity, may contribute to the risk of alopecia areata.

This study suggests that microvascular damage and platelet deregulation may persist in ulcerative colitis patients even during remission, remaining as disease-associated molecular signatures.

This article examines the morphological and physiological characteristics of eyelash follicles and offers clinical management suggestions for conditions like eyelash loss and trichomegaly, but presents no new clinical results.

This paper discusses the pathogenesis of cardiovascular lesions in dogs associated with minoxidil, noting that lesions were not prevented by adrenergic blockade or neural activity suppression, and highlights the differences in injury progression between coronary arteries and the right atrium.

This study found that freezing nitrogen ethanol composite (FNEC) caused less cryoablative damage to surrounding normal tissue than liquid nitrogen in a mouse model of human bone xenograft transplantation.

In this mouse study, aerobic exercise was found to protect the intestinal mucosal barrier in obstructive jaundice by inhibiting the HMGB1 / TLR4 / NF-κB signaling pathway through the H2S / CSE system.

This study observed that COVID-19 infection in cancer patients may worsen lung damage, leading to over a 50% reduction in lung volume and increased lung density due to scar tissue formation.

This study developed a method to convert fibroblasts into sweat gland-like cells, suggesting potential for regenerating damaged skin and restoring sweat gland function.

This study found that melanin extracted from cuttlefish ink provided significant protection against UV radiation damage to human hair, suggesting its potential as a photoprotective agent in hair-care products.

In this study, researchers used a human skin organoid model to show that solar UV exposure damages hair follicles and skin, while exosomes from mesenchymal stem cells reduced inflammation and supported hair follicle regeneration.

This review reports that thallium poisoning causes severe neurological damage, with early gastrointestinal symptoms and later neurological dysfunction, and highlights the importance of early diagnosis and Prussian blue as an effective antidote.

In this study, researchers found that unexplained liver damage in PCOS patients may involve iron metabolism and the miR-761-hepcidin/GPX4 axis, suggesting potential therapeutic targets.

This study found that digital perm treatments using sodium thioglycolate lotion led to the most significant reduction in protein content and greater hair damage compared to other methods and lotions.

This study observed that high concentrations of rosemary and thyme extract caused thymic tissue damage, decreased IgM and IgG levels, and fluctuated IL-10 levels in chick embryos, with inflammation signs present despite potential benefits.

This study found that excessive consumption of cloves in mice caused toxic changes in the liver, including structural damage and cell death, but concluded these effects are not considered dangerous.

This study found that a shampoo containing quaternized wheat protein hydrolysate can effectively improve hair recovery by smoothing and compacting damaged hair surfaces, thanks to modifications that enhance protein adherence and disulfide bond formation at pH levels typical in hair care products.

This study found that PCL-based nanofiber scaffolds enhanced cell proliferation and extracellular matrix deposition, suggesting they show promise as a cell delivery system for improving skin wound healing.

This study found that the differential expression of α- and β-keratin genes in feathers may explain their morphological and structural diversity, highlighting the chicken as a model for studying keratin-related diseases.

This study observed that minoxidil induced myocardial necroses and hemorrhages in beagle dogs and miniature swine, with greater severity seen in dogs.

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 found that applying Hypericum perforatum methanol extract-containing gel to experimental burns in rats reduced collagen discoloration and vascular damage while preserving hair follicles and epidermal thickness compared to treatment with silver sulfadiazine cream.

This review discusses the fundamental hallmarks of aging as they relate to skin aging and highlights the prominent roles of oxidative damage and the extracellular matrix in photoaging, reporting no new results.

This study found that large excisional wounds in mice can regenerate new hair follicles and fat, whereas similar wounds in rats across seven strains failed to do so, highlighting interspecies differences in regenerative capacity.

In a mouse model, this study found that exposure to PM2.5 leads to significant postpartum hair loss, apparent via morphological changes and elevated markers of inflammation, apoptosis, and fibrosis, potentially exacerbated by changes in hormone receptors and stem cell populations.

This study suggests that combining scalp cooling with resveratrol-loaded nanoparticles effectively protects hair follicles from chemotherapy-induced damage, highlighting a potential method to prevent hair loss during cancer treatment.

In this study, researchers investigated age-related hearing loss in advanced-age CBA/CaJ mice and found combined cochlear damage from chronic sound exposure and metabolic changes linked to oxidative stress, which may require addressing both etiologies for prevention and treatment.

In this article, researchers explored how blue light exposure affects the scalp and hair follicles, highlighting oxidative stress and hair growth disruptions, while emphasizing the importance of protective strategies like antioxidants and limiting light exposure.

This study investigated the sub-acute toxicity of Eclipta alba extract in Wistar albino rats, finding generally comparable hematological and biochemical parameters to controls, but noted mild morphological liver and kidney changes at the highest dose, highlighting a key area for further safety research.
