A Novel Antioxidant Peptide Cath‐Np Derived from Nanorana parkeri Attenuates UVB‐Induced Skin Photodamage in Mice

Integrative Zoology, EarlyView.
Schematic representation of Cath‐Np as an antioxidant suppressing acute skin damage caused by ultraviolet B (UVB) radiation in mice. Cath‐Np inhibits the activation of p53 and mitogen‐activated protein kinase pathways while it activates the Nrf2 pathway by its strong antioxidant effects, and accordingly suppresses the expression of inflammatory factors

Inonotus obliquus polysaccharides prevent UVB-induced skin photodamage by modulating Sirt3-activated Foxo3a/PINK1-Parkin pathway: an in vitro and in vivo study

Food Science and Human Wellness
Inonotus obliquus, an edible and medicinal fungus, has proven to be beneficial for relieving body aging. Previous research has shown that I. obliquus polysaccharide (IOP) can effectively reduce oxidative stress and alleviate photoaging in UVB-treated ...

Amphibian‐Derived Peptide OA‐AL14 Alleviates UVB‐Induced Skin Photoaging via Autophagy Activation Mediated by the AMPK/mTOR Pathway

Integrative Zoology, EarlyView.
The schematic diagram illustrates that the amphibian‐derived peptide OA‐AL14 protects against UVB‐induced skin photoaging through a dual mechanism: activating the Nrf2 pathway to counteract oxidative stress and modulating the AMPK/mTOR axis to induce protective autophagy. ABSTRACT Skin photoaging, primarily driven by ultraviolet B (UVB) radiation, is a

Squamoid Eccrine Ductal Carcinoma: Case Series of a Rare, Potentially Aggressive Skin Cancer Associated With Immunosuppression

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Squamoid Eccrine Ductal Carcinoma (SEDC) is a rare cutaneous adenexal carcinoma first described in 1997. It has distinct biphasic features on histology which commonly result in misdiagnosis as Bowen disease or cutaneous squamous cell carcinomas (cSCC) if diagnostic skin biopsies are too superficial. This may lead to a delay in diagnosis. It is

A single‐center prospective observational study evaluating the efficacy and safety of tirbanibulin 1% in actinic keratoses in immunosuppressed patients: the ESTIMATE study

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Summary Background Actinic keratoses (AKs) are common precursors to squamous cell carcinoma and pose a heightened risk in immunosuppressed patients, such as organ transplant recipients (OTRs). Patients and methods This prospective, monocentric, single‐arm observational study investigated the safety and efficacy of topical tirbanibulin 1% ointment in ...

Merkel cell carcinoma: an updated guide for pathologists

Histopathology, 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.

Bakuchiol: From structural mimicry to systems‐level skin biology

International Journal of Cosmetic Science, EarlyView.
Convergent outcomes, divergent mechanisms: bakuchiol vs. retinol. Bakuchiol exhibits functional convergence with retinol in improving extracellular matrix integrity, epidermal differentiation and barrier function, while operating through distinct mechanisms.
