Selective progesterone receptor modulators for the treatment of dysmenorrhea: an update.
Expert Opin Pharmacother
January 2025
Department of Obstetrics and Gynecology, University of Florence, Careggi University Hospital, Florence, Italy.
Introduction: Dysmenorrhea is a painful symptom associated with uterine contractions and menstrual bleeding and is treated by administering analgesic drugs. Since progesterone receptors (PRs) have a major role in regulating uterine tissues (myometrium and endometrium) oral contraceptives are used off-label for treating primary or secondary dysmenorrhea. The development of selective progesterone receptor modulators (SPRMs) a class of synthetic steroids with agonistic, antagonistic, or mixed effects in targeting PRs in different tissues stimulated their possible clinical use for treating secondary dysmenorrhea related to uterine diseases (endometriosis, adenomyosis, uterine fibroids).

We prepared a cellulose nanofiber (CNF)-based porous membrane with three dimensional cellular structures. CNF was concentrated a surfactant-induced assembly by mixing CNF with a cationic surfactant, domiphen bromide (DB). Furthermore, they were accumulated by centrifugation to obtain a CNF-DB sol.

Introduction: Despite the implementation of mechanical thrombectomy, acute ischaemic stroke with large vessel occlusion (AIS-LVO) remains a significant health concern, characterised by substantial morbidity and mortality. Our trial aims to evaluate the efficacy and safety of minocycline in reducing infarct volume and improving functional outcomes in patients undergoing mechanical thrombectomy for anterior circulation AIS-LVO.
Methods And Analysis: The MIST-A trial is a prospective, randomised, open-label, blinded-endpoint trial to be conducted across 12 medical centres.
FRAP Assay to Trace Lipid Mixing of the Inner and Outer Leaflet of Yeast Vacuoles: Assessing the Fusion State in Live Cells.
Methods Mol Biol
January 2025
Department of Immunobiology, University of Lausanne, Epalinges, Switzerland.
Fluorescence recovery after photobleaching (FRAP) can be employed to investigate membrane lipid mixing of vacuoles in live budding yeast cells and distinguish the fused, hemi-fused or non-fused states of these organelles under physiological conditions. Here, we describe a protocol for labeling the outer and inner leaflets of vacuoles in live cells that allow to detect hemifusion intermediates and, thus, identify components necessary for fusion pore opening.

Angew Chem Int Ed Engl

Nanjing University, School of Chemistry and Chemical Engineering, CHINA.
Proximity labeling (PL) has emerged as a powerful technique for the in situ elucidation of biomolecular interaction networks. However, PL methods generally rely on single-biological-hierarchy control of spatial localization at the labeling site, which limits their application in multi-tiered biological systems. Here, we introduced another enzymatic reaction upstream of an enzyme-based PL reaction and targeted the two enzymes to markers indicating different biological hierarchies, establishing a two-level spatially localized proximity labeling (P2L) platform for in situ molecular measurement and manipulation.
