This study found that the enzyme Acer1 plays a crucial role in skin health and tumor prevention by regulating ceramide metabolism in mice.

This study found that Acvr1b signaling is crucial for both hair follicle development and cycling in mice, with the genetic disruption leading to hair loss and a thickened epidermis.

In this study, targeted overexpression of the BMP receptor ALK2 in mouse hair follicle stem cells altered follicle structure and impaired cutaneous wound healing.

In this study, the ACE1 rs1799752 polymorphism was not found to predispose COVID-19 survivors to long-COVID symptoms, supporting previous findings that ACE2 and TMPRSS2 variants also do not influence post-COVID conditions.

Tocilizumab might be an effective treatment for COVID-19.

Finasteride may help reduce symptoms in male Tourette syndrome patients.

This study describes the prescribing habits of Spanish dermatologists, highlighting that topical minoxidil and oral finasteride are the most common treatments for male AGA and postmenopausal female AGA.

In this descriptive retrospective study, researchers reported that low-dose oral minoxidil (0.25-5mg/day) for androgenic alopecia demonstrated a good safety profile, with 84.4% of 641 patients experiencing no adverse effects and only 1.4% discontinuing due to side effects that resolved with dose reduction or withdrawal.

This study found that mice lacking alkaline ceramidase 1 with elevated skin ceramide levels showed disrupted skin homeostasis, including altered hair follicle structures, increased water loss, and a hypermetabolism phenotype.

This study found that loss of the ACER1 gene in mice led to increased ceramide levels and progressive hair loss, highlighting ACER1's role in maintaining hair follicle stem cell homeostasis.

This study reports new fluorogenic ceramidase substrates and highlights RBM14C24:1 as an efficient substrate for neutral ceramidase, while RBM15C18:1 is the best probe for measuring ACER1 and ACER2 activities, potentially aiding high-throughput screening for ceramidase inhibitors.

In this study, extracts from Chenopodium quinoa, Glycine max, and Malpighia emarginata demonstrated stability, low toxicity, and effective cleaning potential as surfactants in shampoo formulations, showing performance similar to or better than commercial shampoos in terms of surface and interfacial tension and sebum removal.

In this study, researchers identified key miRNAs and target genes involved in hair follicle development in Merino sheep, providing insights that could aid in improving sheep breeding for wool quality.

This study found that miR-23b and miR-133 significantly reduce mRNA and protein levels of specific target genes involved in Merino sheep hair follicle development, providing insight into molecular breeding for fine wool production.

This paper considers fibrodysplasia ossificans progressiva as a segmental progeroid syndrome, which may help uncover mechanisms of normal aging and suggest targets for new treatments.

This article discusses the major role of motor vehicles in contributing to urban air pollution and its significant health impacts, especially in developing countries, but reports no new findings.

The researchers reported that using Natesto® testosterone gel improved erectile function and mood in hypogonadal men over a 90-day period.

This review discusses various alternative treatments for androgenetic alopecia, including pharmacological, surgical, and herbal therapies, without presenting new clinical findings.

This review discusses various treatment options for androgenic alopecia, noting finasteride's greater efficacy in men and identifies ongoing research needs, particularly for therapies like laser and stem cells.

This article reviews dermatological research on black skin, emphasizing its unique physiological characteristics and common conditions like acne and eczema, and suggests more focus is needed on its structural differences and clinical responses.

In this study, researchers reported that individuals with post-COVID-19 alopecia experienced a significant impact on their quality of life, particularly in the vitality domain, when compared to those without alopecia.

This study reported that among individuals with long COVID, hematologic disturbances such as inflammation-related anemia, characterized by high hepcidin levels and restricted iron use, were prevalent, contributing to reduced capacity, fatigue, and slow recovery, especially in men and those with severe acute COVID-19.

This integrative literature review found that hydroxychloroquine may stabilize inflammatory scarring autoimmune alopecias like frontal fibrosing alopecia, especially when combined with other therapies, while its effectiveness in non-scarring alopecias appears inconsistent and is limited to refractory cases.

This report emphasizes the importance of considering thyroid tuberculosis in the differential diagnosis of cervical masses, highlighting the role of biopsy and histopathological examination for accurate diagnosis and treatment.

This integrative review found that triamcinolone hexacetonide remains the primary treatment for mild to moderate alopecia areata but noted its significant side effects with prolonged use, while emerging therapies like PRP and minoxidil offer promising alternative benefits with fewer risks.

This review reports that post-COVID telogen effluvium may be influenced by immune and psychological factors linked to COVID-19 infection, affecting hair loss.

This narrative review discusses adverse effects associated with 5-ARI treatments for male-pattern baldness and benign prostate hyperplasia, including sexual health, neurological, endocrine, metabolic, and cardiovascular impacts, and emphasizes careful prescription assessment.

This article discusses the organizational aspects of the II National Academic Congress of Dermatology in Brazil and reports no new research findings.

The I National Academic Congress of Dermatology in 2021 expanded to include participants from across Brazil and discussed dermatology topics, including COVID-19.

This article discusses vaccination coverage for BCG, Polio, and Hepatitis B in Juiz de Fora using SUS data and reports no new results; the authors aim to hypothesize reasons for coverage variation.
