A guide to host genetic determinants of female microbiome composition across distinct anatomical niches

open access: yesThe FEBS Journal, EarlyView.
Host genetic variation in immune regulation and cell signalling genes was associated with microbiome composition across vaginal, gut, oral and skin sites, while associations involving metabolic function, epithelial barrier integrity and hormonal processes were more site‐specific. Overall, our findings indicate that host genetic variation contributes to

Merkel cell carcinoma: an updated guide for pathologists

open access: yesHistopathology, EarlyView.
Merkel cell carcinoma (MCC) is an aggressive cutaneous neuroendocrine carcinoma for which the differential diagnosis can include other small cell malignancies (especially metastatic small cell carcinoma) or cutaneous carcinoma. Morphologic and immunophenotypic aberrancies in MCC can increase diagnostic challenge.

Novel and emerging skin carcinomas and adnexal tumours

open access: yesHistopathology, EarlyView.
The present review aims to provide an overview of the main emerging skin epithelial tumours, with particular emphasis on salivary gland analogue sweat gland tumours and poorly differentiated carcinomas. Epidermal and adnexal tumours of the skin constitute a complex and heterogeneous group of neoplasms, with distinct morphology and behaviour.

Seasonal variation in preen gland secretions of Tristram's Storm Petrel (Hydrobates tristrami)

open access: yesIbis, EarlyView.
Preen gland secretions are known to vary depending on sex, season and species and are thought to play essential roles in avian life history. However, their chemical composition and functions remain largely unclear in Procellariiform seabirds with well‐developed olfactory senses. Storm petrels, known for their distinctive body odour, may use preen gland

Development of Artificial Sebaceous Gland‐Integrated In Vitro Human Skin Model

open access: yesAdvanced Materials Interfaces
Sebum plays a critical role in maintaining skin homeostasis, but its overproduction is associated with pore enlargement, acne, and other dermatological conditions.

Sebum output as a factor contributing to the size of facial pores

open access: yes, 2006
BACKGROUND: Many endogenous and exogenous factors are known to cause enlarged pilosebaceous pores. Such factors include sex, genetic predisposition, ageing, chronic ultraviolet light exposure, comedogenic xenobiotics, acne and seborrhoea.

Unravelling polyphenol skin permeation: A comparative study using full‐thickness 3D in vitro and ex vivo human skin models

open access: yesInternational Journal of Cosmetic Science, EarlyView.
This study demonstrates that full‐thickness 3D in vitro skin models reliably assess the permeation of cosmetic polyphenols, revealing compound‐specific transport profiles and bridging the gap between conventional cell models and ex vivo human skin, while offering an ethical and robust alternative for dermal absorption screening. Abstract The evaluation

Synergistic Effects of Solar Exposure and Skin Sensitivity on Skin Aging: A Clinical Study Using Multimodal Noninvasive Measurements. [PDF]

open access: yesSkin Res Technol
ABSTRACT Background Solar exposure is the primary extrinsic factor contributing to skin aging. Sensitive skin, characterized by impaired barrier function and heightened reactivity, may be more vulnerable to solar‐induced damage. However, the potential interaction between skin sensitivity and solar exposure in accelerating skin aging has not been ...
