Discrepancy in the use and interpretation of marker sutures among plastic surgeons and pathologists.

J Clin Pathol 2022 Jun 28. Epub 2022 Jun 28.

Plastic Surgery, University Hospital of North Staffordshire NHS Trust, Stoke-on-Trent, UK.

Marker sutures are often used for excised cutaneous lesions to aid histological analysis, however, there are no current guidelines to facilitate this in practice. The authors hypothesised that a lack of guidelines causes a variation in clinical practice and confusion of meaning between plastic surgeons and pathologists. This questionnaire-based study confirms the authors' hypothesis and highlights a discrepancy both between surgeons and in individual surgical practice. Read More

EMILIN-1 deficiency promotes chronic inflammatory disease through TGFβ signaling alteration and impairment of the gC1q/α4β1 integrin interaction.

Matrix Biol 2022 Jun 25. Epub 2022 Jun 25.

Unit of Molecular Oncology, Centro di Riferimento Oncologico di Aviano (CRO), IRCCS, Aviano, Italy.

Alterations in extracellular matrix (ECM) components that modulate inflammatory cell behavior have been shown to serve as early starters for multifactorial diseases such as fibrosis and cancer. Here, we demonstrated that loss of the ECM glycoprotein EMILIN-1 alters the inflammatory context in skin during IMQ-induced psoriasis, a disease characterized by a prominent inflammatory infiltrate and alteration of vessels that appear dilated and tortuous. Abrogation of EMILIN-1 expression or expression of the EMILIN-1 mutant E933A impairs macrophage polarization and leads to imbalanced tissue homeostasis. Read More

Advanced harmonization techniques result in accurate establishment of in vitro-in vivo correlations for oxybenzone from four complex dermal formulations with reapplication.

Drug Deliv Transl Res 2022 Jun 28. Epub 2022 Jun 28.

Department of Pharmaceutical Sciences, School of Pharmacy, University of Maryland, 20 North Pine Street, Baltimore, MD, 21201, USA.

Due to high variability during clinical pharmacokinetic (PK) evaluation, the prediction of in vivo exposure from in vitro absorption testing of topical semisolid and liquid dermal products has historically proven difficult. Since absorption from unoccluded formulations can be influenced by environmental factors such as temperature and humidity, maximal effort must be placed on the harmonization of experimental parameters between in vitro and in vivo testing conditions to establish accurate in vitro/in vivo correlations (IVIVC). Using four different sunscreen formulations as a model, we performed in vitro permeation testing (IVPT) studies with excised human skin and maintained strict harmonization techniques to control application time, occlusion, temperature, and humidity during in vivo human serum PK evaluation.
