Inspired by natural microbial cooperation, a co-culture approach was used to synthesize bacterial nanocellulose (BNC)-based nanocomposites for potential wound healing applications. By co-culturing either Komagataeibacter xylinus (K1G4) or the never tested strain K. rhaeticus (K2G46) with the hyaluronic acid (HA)-producer Lacticaseibacillus casei UMCC 2535, two BNC-HA nanocomposites were obtained (C1-K1 and C2-K2).

Little evidence exists on the causal mechanisms, but emerging experimental evidence suggests a role for reward-related impulsivity. Recent work experimentally increased reward-related impulsivity to increase drinking using standardised reward-cue stimuli.

Little is known about how social media impacts young peoples' drinking behaviours and drinking-related consequences. This cohort study aims to explore the prospective relationship between social media use and future drinking.

- Obesity rates are rising worldwide, with food addiction (FA) possibly playing a significant role; however, the psychological factors behind FA remain unclear.
- The bioSocial Cognitive Theory (bSCT), traditionally used for substance use, was tested in this study to understand FA in eating behaviors by introducing punishment sensitivity, showing that it offers a better fit than the original model.
- The findings indicate that individuals who are drawn to rewards and are sensitive to punishments tend to overestimate the emotional benefits of eating, which could lead to a higher risk of food addiction, highlighting potential areas for intervention.
Bacterial cellulose synthesis from defined media and waste products has attracted increasing interest in the circular economy context for sustainable productions. In this study, a glucose dehydrogenase-deficient Δgdh K2G30 strain of Komagataeibacter xylinus was obtained from the parental wild type through homologous recombination. Both strains were grown in defined substrates and cheese whey as an agri-food waste to assess the effect of gene silencing on bacterial cellulose synthesis and carbon source metabolism.
