This study found that decision-making effects related to time of day and chronotype were only significant when using RNA-based chronotype measurements, indicating molecular clock differences may influence these behaviors.

This research analyzed two ancient mammoth hair strands and reported distinct structural and elemental differences, including calcium, iron, and copper deposits, which vary with age and origin.

This review discusses skin disorders in women of color, highlighting unique presentations like dyschromias from acne, and underscores the need for more research on racial and ethnic differences; it reports no new clinical results.

This article reviews botulinum toxin use in men, focusing on anatomical and treatment differences, with no new clinical results.

The study concluded that the Exprecell™ device for preparing anticoagulant-free f-PRF increases volume yield and simplifies the process while maintaining biological activity comparable to conventional methods, suggesting potential clinical utility.

This study found that the type of reporter significantly influences the detection of cancer therapy-induced alopecia signals, highlighting differences in signal amplification between patients and healthcare professionals.

This study found that compound 10 inhibited testosterone conversion to DHT in hamster flank organs and seminal vesicles, whereas compound 11's inhibitory effect varied with dose, linked to halogen electronegativity differences.

This article reviews the varied clinical outcomes of using platelet-rich plasma for connective tissue healing, highlighting inconsistencies due to differences in PRP preparations and applications, and reports no new clinical findings.

In this study, researchers found that in mice, gonadal hormones and biological sex do not affect the expression of SARS-CoV-2 entry proteins ACE-2 and TMPRSS-2 in the respiratory tract, regardless of disease state.

This paper reports on various AI and human augmentation technologies being applied in plant biology to enhance data processing, improve research efficiency, and enable the discovery of complex biological phenomena that are challenging for humans to perceive or quantify unaided.

This study found that puppies fed organic selenium had better retention of selenium compared to those fed inorganic selenium, with no significant difference in coat quality or hair growth.

This study evaluated an in vitro inhalation method to assess the toxicological impacts of aerosols from heated hair products, revealing significant differences in cellular stress and IL-8 release among different test materials, which may help in developing safer products.

This review summarizes recent developments in dermatology, including advancements in imaging techniques, biologics, and controversies in treatment, but presents no new clinical findings.

Different treatments for skin conditions were found to be effective and generally safe, with biologics recommended as the first choice for generalized pustular psoriasis.

This review discusses the use of platelet-rich plasma for various dermatological conditions and highlights the need for more research to standardize its protocols and understand its biological mechanisms.

This article emphasizes the need for dermatology to treat gender identity, gender, and sex as distinct factors, aiming to improve patient-specific risk assessment and treatment alignment, and highlights a research gap in distinguishing sex and gender as separate risk factors in the field.

This article discusses how racial essentialism impacts health professions education by increasing prejudice and reducing empathy, and it suggests reforms to emphasize racism as a cause of health inequity, without presenting new research data.

This study suggests that using combined oral contraceptives does not increase hair glucocorticoid levels, but hair treatments should be considered as a confounder in stress biomarker assessments.

This commentary suggests that shifting from inconsistent autologous PRP to more standardized PRP-inspired formulations could improve treatment consistency for alopecia, emphasizing the need for careful characterization and clinical studies to validate safety and efficacy.

This article reviews literature indicating that specific dermatoses manifest differently in black skin compared to lightly pigmented skin, with some conditions more prevalent or unique to black skin, emphasizing the need for tailored clinical recognition and management.

This study identified 77 genes with significant expression changes in expanded human skin, suggesting possible mechanisms for skin regeneration during tissue expansion, including previously unreported genes like HOXA5, HOXB2, and AP1.

This study observed that hair cortisol concentrations in primates are influenced by factors such as age, sex, hair growth rates, and sampling methods, which must be accounted for in research designs.

This study analyzed gray hair, revealing that it differs from pigmented hair in follicular activity, oxidative balance, and structure, impacting coloring processes and necessitating adapted techniques to maintain hair quality.
