NAD+‐Dependent Enzyme SIRT3 Limits Intestinal Epithelial Cell Functions Through NAD+ Synthesis Pathway in Colorectal Cancer

open access: yesAdvanced Science, EarlyView.
Microbiota‐derived quinolinic acid is used as an alternative source of replenishing the intracellular NAD+ pool induced by SIRT3 deficiency to regulate intestinal epithelial cell and T cell function, which has implications for targeting intestinal epithelial cells as an approach to the treatment of immune‐associated diseases, including colorectal ...

Catalyst‐Free Collagen Filament Crosslinking for Engineering Anisotropic and Mechanically Robust Tissue Scaffolds

open access: yesAdvanced Science, EarlyView.
A bioorthogonal rhodamine/PEG crosslinking strategy is introduced to engineer dense collagen hydrogels with high mechanical resilience and cytocompatibility. Integration with wet‐spinning enables the fabrication of uniaxially aligned, cell‐laden collagen filaments that activate mechanotransductive signaling and support functional muscle regeneration in

Combining Electrochemical Reduction with Biosynthesis for Directed Conversion of CO2 into a Library of C3 Chemicals

open access: yesAdvanced Science, EarlyView.
In the H‐type electrolytic cell, carbon dioxide is reduced to acetic acid via electro‐microbial catalysis. The simply processed acetic acid is further converted through biological fermentation into high‐value‐added products, including acrylic acid, L‐lactic acid, and β‐alanine.

Psilocybin Production With Genetically Modified Aspergillus nidulans Under Pressurized Conditions

open access: yesBiotechnology and Bioengineering, EarlyView.
Shake flask cultures of psilocybin‐producing A. nidulans were investigated with respect to nitrogen source, rheology, power input, and oxygen availability, and subsequently scaled to a stirred tank reactor scale based on specific power input to develop and optimize a pressurized bioprocess.

Contact Allergy to Ingredients of Hair Cosmetics Associated with Occupational and Non‐Occupational Exposure—Trends from 1995 to 2020 in Central Europe, with or without Regulation

open access: yesContact Dermatitis, EarlyView.
Among 2678 female hairdressers and 6244 female consumers with contact dermatitis suspected to be related to use of hair cosmetics, including dyes, patch tested in the IVDK between 1995 and 2020, diverging contact allergy trends were observed. In the case of toluene‐2,5‐diamine (PTD) shown in the figure, sensitization was at a stable, high level in ...
