Fibrotic disorders, such as idiopathic pulmonary fibrosis, are characterized by the accumulation of myofibroblasts, cells responsible for excessive extracellular matrix deposition and tissue remodeling. The inability to terminate this reparative process leads to persistent fibrosis with increasing age. GHK (glycyl-L-histidyl-L-lysine], a naturally occurring peptide, has demonstrated the potential in modulating fibrotic pathways by reversing cellular senescence and inducing apoptosis in myofibroblasts. GHK promotes tissue regeneration and enhances wound healing by activating stemness markers like p63 and PCNA. In aging, GHK's effect on pulmonary fibroblasts may restore youthful phenotypes, improving fibroblast migration and collagen contraction. This commentary discusses the role of GHK in resolving persistent fibrosis and the molecular mechanisms underpinning these effects, including integrin-β1 signaling. The potential of GHK as a therapeutic agent for fibrosis, including combination strategies with antioxidants or anti-inflammatory agents, is also explored.

To address the increasingly limited water availability, using metal-organic frameworks (MOFs) to capture atmospheric water vapor as usable resources has emerged as a promising strategy. The adsorption characteristics of MOFs as well as their step pressure (i.e.

Biofouling often occurs simultaneously with fogging, presenting significant challenges to visibility, safety, and operational efficiency. The development of biocompatible coatings that offer both antifouling performance and stability under fogging conditions is highly sought after. A method to form multifunctional coatings is presented, utilizing a zwitterionic nanocellulose composite material that demonstrates both antifogging and antifouling properties, suitable for application on various surfaces.

Introduction: Women who experience postpartum hemorrhage (PPH) after giving birth rapidly lose blood, which may lead to shock or death without immediate intervention. PPH most often results from uterine atony, when the uterus fails to contract after delivery. Worldwide, PPH causes 10 deaths hourly, with most deaths occurring in low-income settings.

Unlabelled: (SA) colonizes most mammals but also represents a danger in clinical settings because it evolves resistance against antibiotics, and SA infections represent a leading cause of death worldwide. SA nasal carriage provides the bacterial reservoir for opportunistic infection because clinical strains often match the patient's own nasally carried strain. The global SA carriage rate is typically reported as 25%-30% after sampling subjects once or twice and defining carrier status using culture-based methods.

In an attempt to react aminocyclopropenones with cyclic imines in order to synthesise amido-substituted pyrrolizidine natural products, we found that aminocyclopropenones undergo a previously unreported stereospecific and regiospecific catalyst-free, thermal ring-opening reaction with alcohols to yield β-enamino esters (also known as vinylogous carbamates or aminoacrylates). We report 21 examples in 45 to 97% isolated yield. The reaction occurs nucleophilic attack at the cyclopropenone carbonyl followed by regiospecific ring opening of the cyclopropenone with retention of alkene geometry.
