In this study, expressing human K16 in the epidermis of K14 null mice prevented early skin blistering but led to age-related anomalies, indicating K16 and K14 have distinct roles despite their sequence similarity.

This study found that hydroquinone caused structural damage to the skin of rats, while aloe vera reduced this damage, suggesting potential concerns for its use in skin lightening creams.

A missing mK6irs1 gene causes hair loss in mice.

In this study, thymosin beta4 over-expression in transgenic mice was linked to accelerated hair growth and abnormal tooth development, suggesting roles in hair and tooth physiology.

This study reported that applying a cream with 5% vitamin C reduced dermatoporosis-related purpura, suggesting the condition may be linked to vitamin C deficiency.

In this study, researchers found that washing hair 5–6 times per week results in higher satisfaction and better objective and subjective hair and scalp conditions among Asian populations, with no observed detrimental effects from frequent washing.

This study reports that analyzing the clinical manifestations of different genetic variants in EBS families helps predict disease progression and severity, guide complication risk assessment, and plan necessary medical care.

This study developed an in vitro model using NTERT keratinocytes expressing AEC-related TP63 mutations, which replicated skin defects observed in AEC patients and offers a valuable tool for understanding the disorder and developing new treatments.

This source reviews the common skin-related side effects of tyrosine kinase inhibitors in treating endocrine cancers and emphasizes that proactive, multidisciplinary management can effectively control these adverse events without compromising cancer treatment efficacy.

Finasteride significantly increases scalp hair and prevents hair loss in young and middle-aged men.

This case report describes a young girl with trichothiodystrophy and suggests the need for early diagnosis and multidisciplinary interventions for her educational challenges.

This review examines the direct-to-consumer genetic testing market, highlighting the available tests, regulatory issues, and calls for increased oversight, and reports no new results.

In this study, researchers found that substance P triggered premature catagen development and immune changes in human scalp hair follicles, providing a possible biological link between stress and hair loss conditions like telogen effluvium and alopecia areata.

In this study, older men using 5α-reductase inhibitors for prostatic enlargement did not show increased risk of suicide, but had elevated risks of self-harm and depression.

In this study, patients with androgenetic alopecia treated with platelet-rich plasma showed increased hair density and improved hair quality over six months, with no notable adverse effects, indicating that PRP may be an effective treatment option for this condition.

In this study, cosyntropin-induced cortisol spikes did not affect hair cortisol concentration in captive grizzly bears, contrasting with stress responses observed in free-ranging bears during capture.

In this study on tolerant rats, maternal and developmental toxicity from levo-alpha-acetyhnethadol hydrochloride were observed at all doses, without specific fetal toxicity or teratogenic effects.

In this study, androgenic alopecia was identified as an independent predictor of abnormal white matter hyperintensities in the brain, suggesting it may serve as a surrogate marker for cerebral small vessel disease linked to arteriolosclerosis.

Finasteride increases hair density in female androgenetic alopecia, but individual results may vary.

Insulin resistance linked to obesity may increase COVID-19 severity.

Finasteride increases hair growth, prolongs hair cycle, and lowers dihydrotestosterone levels.

This study found that the PON1 192 R allele was associated with an increased risk of psoriasis and altered lipid profiles in patients from Western Mexico.

Spironolactone use is not linked to an increased risk of breast cancer, but caution is advised for high-risk patients.

A Western diet may increase acne risk, while a Mediterranean diet and certain supplements can help reduce it.

This article reviews the clinical complications and increased mortality risks associated with Cushing's syndrome but does not present new clinical data; it emphasizes the need for prompt treatment to mitigate these risks.

This study highlights that prolonged voriconazole use is linked to an increased risk of aggressive cutaneous malignancies like squamous cell carcinoma, necessitating careful monitoring of drug levels to manage adverse effects.

This study found that cysteine supplementation significantly increases keratin expression in human keratinocytes, and counteracts the negative impact of iron deficiency on keratin production by enhancing iron availability for cellular processes.

This study found that dutasteride is not associated with an increased risk of osteoporosis or fractures in older men compared to finasteride, suggesting dutasteride does not adversely affect bone health.

This study found that while MK-0773 significantly increased lean body mass in sarcopenic frail elderly women, it did not significantly improve muscle strength or physical function compared to placebo.

This study found that stress increases the number of peptidergic nerve fibers and mast cell activity in mouse skin, suggesting a significant neuro-immune interaction under stress.
