Raman Signature of the Wings of the Globe Skimmer Dragonfly: Pantala flavescens

Journal of Raman Spectroscopy, EarlyView.
Raman spectroscopy is used to confirm the presence of aliphatic and aromatic hydrocarbons and related derivatives including aldehydes, halides, alcohols, acids, esters, and phenols on the wings of Pantala flavescens. The analysis indicates that wing‐surface lipid composition is largely consistent across the three main ecological zones in Ghana. Notably,

Melatonin Exerts Chondroprotective Effects Against Osteoarthritis by Promoting PI3K/AKT/FoxO3‐Mediated Mitophagy

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Osteoarthritis (OA) is a prevalent degenerative joint disease. This study combines bioinformatics analysis with in vivo and in vitro experiments to elucidate the molecular mechanisms through which melatonin (MT) regulates mitophagy to alleviate OA.

Valproic Acid Inhibits Ferroptosis and Improves Bone Integration in OVX Rats Through the AMPK/SIRT1 Pathway

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT The prevalence of postmenopausal osteoporosis (PMOP) has been steadily increasing. Ferroptosis has been recognized as a critical factor influencing the bone‐forming ability of bone marrow mesenchymal stem cells (BMSCs). Valproic acid (VPA), an HDAC inhibitor, has been suggested to play a role in regulating osteoporosis development; however ...

Fiber Reinforcement of Soft Spider Silk Hydrogels

Macromolecular Rapid Communications, EarlyView.
Along the development of matrices for biomedical applications, precise tuning of the biomaterial to interact with specific cell types/tissues is essential. The fabrication of fiber mesh‐reinforced soft hydrogels made of recombinant spider silk proteins allows for the adjustment of mechanical properties and hydrogel porosity, leading to improved cell ...

Juvenile hormone‐mediated accelerated post‐flight recovery of ovarian development in Loxostege sticticalis (Lepidoptera: Crambidae)

New Plant Protection, EarlyView.
Flight in female beet webworms (Loxostege sticticalis) promotes an increase in feeding, thereby enhancing abdominal energy reserves. Following flight, the flight muscles undergo accelerated histolysis, and the energy substances undergoing histolysis are redirected to the ovaries. These two processes collectively promote ovarian development.

Refractory Lung Diseases: From Cellular Structures, Molecular Mechanisms to Therapeutic Strategies

Pediatric Discovery, EarlyView.
ABSTRACT Refractory lung diseases (RLDs) encompass a spectrum of progressive pulmonary disorders, including acute respiratory distress syndrome (ARDS), bronchopulmonary dysplasia (BPD), and idiopathic pulmonary fibrosis (IPF). These conditions are defined by poor responsiveness to current therapeutic interventions and pose substantial clinical ...

Image Analysis Platform for Comprehensive Quantification of Extracellular Vesicle Morphology

PROTEOMICS, EarlyView.
ABSTRACT Extracellular vesicles (EVs) are membrane‐encapsulated nanoparticles with key roles in cell biology and growing importance in biomedicine. However, EVs are challenging to characterize because they are highly heterogeneous. Single EV analysis methods are valuable tools for addressing this challenge.
