Microbial colonization and development of infections in wounds is a sign of chronicity. The prevailing approach to manage and treat these wounds involves dressings. However, these often fail in effectively addressing infections, as they struggle to both absorb exudates and maintain optimal local moisture.

- - The study aims to enhance face masks by incorporating antiviral essential oils (EOs) into electrospun fibrous mats made of polycaprolactone (PCL), which can actively affect the viability of viruses like SARS-CoV-2.
- - Three effective EOs—lemongrass, Niaouli, and eucalyptus—were identified and tested, showing significant virucidal concentrations against the MS2 virus, a potential analog for SARS-CoV-2.
- - The modified mats demonstrated superhydrophobic properties, good mechanical resilience, and effective virus retention, making them potentially superior protective elements in masks compared to traditional options.
Article Synopsis
- * The study investigates how zinc transporters in vacuoles influence AA-induced RCD, with findings suggesting that zinc can protect against cell death and enhance ethanol production.
- * Deleting the vacuolar zinc transporter Zrt3 makes yeast more resistant to acetic acid and improves ethanol yield, indicating this genetic modification could strengthen yeast strains for industrial bioethanol production.
Inflammatory bowel disease (IBD) is a group of disabling, destructive and incurable immune-mediated inflammatory diseases comprising Crohn's disease (CD) and ulcerative colitis (UC), disorders that are highly prevalent worldwide and demand a large investment in healthcare. A persistent inflammatory state enables the dysfunction and destruction of healthy tissue, hindering the initiation and endurance of wound healing. Current treatments are ineffective at counteracting disease progression.

Hydrogel-based scaffolds have been a recurrent solution in both cases, with some reaching already the market, even though their mechanical stability remains a challenge. To overcome this limitation, reinforcement of hydrogels with fibers has been explored.

Essential oils (EOs) exert quick and efficient antimicrobial (AM) action, unlikely to induce bacterial resistance. Cinnamon leaf and clove oils (CLO and CO) display strong AM activity, namely against and .
