This study indicates that individuals exposed to PPD mount varying immune responses, with either tolerance, subclinical inflammation, or allergy, suggesting no true non-responders to PPD.

This observational study reports that a TRASER device using specific wavelengths for vascular and follicular targets showed both clinical responses and histological changes, suggesting its potential as an effective vascular and hair removal tool.

This study found that UVA blocker-containing sunscreens instantly reduced follicular fluorescence due to porphyrins in facial skin, with the effect lasting for a few hours, influenced by sunscreen amount and formulation.

This study found that insulin resistance varies across different PCOS phenotypes, with the PCOM+MI+HA phenotype showing higher resistance than others.

In this case report, photosensitization occurred in Shorthorn calves from three herds in Missouri, with skin lesions and mild liver damage, but affected calves recovered within three weeks.

This study found a strong correlation between antioxidant activity and phenolic content in rosemary, influenced by bioclimatic and seasonal factors in different stages of Tunisia.

A new cosmetic cream reduced facial redness and skin temperature after 4 weeks of use.

This review discusses thallium poisoning, its mechanisms, clinical symptoms, and treatment approaches, highlighting hemoperfusion as an effective method to eliminate absorbed thallium, though no new clinical results are presented.

This study found that specific TRPM5 modulators are unlikely to directly affect sebaceous glands, but safe TPPO analogues may provide moderate lipogenic and anti-inflammatory effects beneficial for dry skin conditions.

Hair coloring and bleaching can permanently break down hair protein and temporarily change its properties.

This study found that UVB exposure led to visible tanning and distinct DNA methylation changes in pigmentation genes in tan-capable skin but not in non-tan skin, highlighting GNAS as a potentially UVB-responsive gene.

This study systematically reviewed literature on paradoxical reactions during biologic treatments for psoriasis, identifying immune dysregulation mechanisms and diverse clinical manifestations, highlighting that mild cases often respond well to topical treatments, while severe cases may require switching to different IL-23 inhibitors.

This study observed that mercury-lamp irradiation may cause cleavage of disulfide bonds in keratins of white hair, leading to the formation of thiols in laboratory settings.

This study found that biotinoyl tripeptide-1-loaded solid lipid nanoparticles significantly improved thermal protection in hair, enhancing cuticle integrity and resistance to heat damage, compared to control samples.

This study found that the tetrazolium salt INT is the most effective for revealing dehydrogenase activity and certain histological structures in sheep and other mammals' skin.

This study found that mice lacking syndecan-1 experienced cold stress and metabolic issues due to reduced intradermal fat, which was restored by thermoneutral housing or rosiglitazone treatment.

In this study, cell membrane remodeling with a thermoresponsive boronic acid copolymer was shown to rapidly form spheroids from cancer or cardiac cell lines under standard conditions, promising advances in tissue engineering.

A patient's skin rash did not affect the area where a previous viral rash was healing, suggesting a rare immune response.

This study found that TRP-hair essence significantly protected and improved the quality of human hair, particularly against heat stress, by enhancing cuticle health and maintaining hair color.

This study reported that a low color temperature light (1900 K) may have positive effects on melatonin secretion, eye protection, wound healing, and hair regeneration compared to higher temperature lights.

This review explores the diverse roles of TRPV1, emphasizing its involvement in both pain and non-pain-related functions, but reports no new clinical results.

This study found a high concordance between subject-reported and clinician-reported Fitzpatrick Skin Phototypes, but 14% of subjects misjudged their skin type, often overestimating it.

This study presents a method for directly measuring the solubility of solid chemicals in the skin's stratum corneum under various humidity conditions, emphasizing its importance for dermal drug delivery and chemical safety assessments.

This study introduces a hypothesis that elevated DHT at puberty may cause chronic thermal stress in specific scalp areas, potentially explaining Androgenetic Alopecia characteristics and guiding future research.

This report suggests that a severe reaction involving dermatitis, alopecia, and fever in a patient receiving aurothioglucose was likely allergic, as indicated by clinical findings and a positive lymphocyte transformation test.

This review found that insulin resistance is a significant independent factor in the development of various inflammatory skin diseases, often linked with obesity and metabolic disorders, and suggests measuring HOMA-IR in affected patients.

Chemical treatments damage hair more than UV exposure, making it thinner and less flexible.

In this case report, a 70-year-old woman with a history of autoimmune hypothyroidism experienced alternating hypothyroidism and hyperthyroidism over a decade, highlighting the potential role of thyrotropin receptor autoantibodies in these fluctuations.

This case report highlights a rare instance of permanent hair loss caused by an allergic reaction to a mesotherapy mixture containing triamcinolone acetonide, suggesting that hypersensitivity reactions to such mixtures are possible.

In this case report, a novel heterozygous mutation in the insulin receptor gene was identified in an adolescent girl with type A insulin resistance syndrome, characterized by excessive hair growth and skin changes, and her mother.
