Development of an enhanced liver scaffold recellularization using fibronectin.

Decellularized liver scaffolds offer a promising foundation for liver tissue engineering and regenerative medicine. However, several challenges such as poor cell adhesion, inefficient reseeding, inadequate vascularization, and a high risk of blood clot formation continue to hinder their clinical application. While fibronectin (FN) has been widely used to enhance scaffold functionality, its potential for liver-specific applications remains largely unexplored.

Spatial transcriptomics of the aging mouse brain reveals origins of inflammation in the white matter.

To systematically understand age-induced molecular changes, we performed spatial transcriptomics of young, middle-aged, and old mouse brains and identified seven transcriptionally distinct regions. All regions exhibited age-associated upregulation of inflammatory mRNAs and downregulation of mRNAs related to synaptic function. Notably, aging white matter fiber tracts showed the most prominent changes with pronounced effects in females.

Antibiotic prescribing patterns in the community and primary care settings through a gender lens: A systematic review.

Objectives: Gender differences affect exposure to infections, including drug-resistant ones. However, data on the relationship between gender and antibiotic use are limited. This systematic review examines gender differences in antibiotic prescribing patterns in community and primary care settings.

Memory-like NK cell differentiation, inhibitory NKG2A blockade, and improved recognition via antibody or CAR engineering combine to enhance NK cell attack against multiple myeloma.

Natural killer (NK) cells are a promising approach for cellular cancer immunotherapy and are being investigated to treat patients with multiple myeloma (MM). We found that MM patient blood NK cell frequencies were normal with increased activating receptors and cytotoxic granules, without evidence of functional exhaustion. Despite this activated state, MM target cells were resistant to conventional NK cells by unclear mechanisms.

Biofilm associated growth inhibition of XDR Escherichia fergusonii strain ACE12 isolated from soil.

Biofilm formation by bacteria is highly recognized for virulence factors resulting in their resistance to antimicrobials that lead to biofilm-associated infections. In this study, we isolated Escherichia fergusonii from soil, characterized its biofilm-associated growth, and evaluated the inhibitory potential of anti-biofilm compounds. Test isolate ACE12 was precisely identified as E.

Growth Performance, Dietary Enzyme Profiling, and Antioxidant-Induced Immunity of Fed With Microalgal Diet.

Diseases, overfishing, and habitat loss are constantly reducing oyster populations. Moreover, environmental pollution and natural disasters also hinder offshore shellfish cultivation. Therefore, filter-feeding bivalves could be cultivated on land-based system to maintain the culture condition and secure food safety.
