Oral Recombinant Human Collagen III Protects Gastric Mucosa via G‐Quadruplex‐Mediated Activation of the Pla2g4a‐Prostaglandin Axis

Advanced Science, EarlyView.
Orally administered recombinant human type III collagen protects the gastric mucosa from ethanol‐induced injury by coordinating redox homeostasis, epithelial barrier repair, and arachidonic acid–prostaglandin metabolism. Gastric digestion releases the pentapeptide GPAEF, which interacts with the Pla2g4a promoter G‐quadruplex in a structure‐dependent ...

An integrated decision-support framework for optimal calf weaning by South African beef cattle producers: A best fit framework review synthesis

Heliyon
Calf weaning plays a fundamental role in the sustainability of cow-calf production systems. The choice of weaning age whether early weaning (EW) or conventional weaning (CW) significantly affects cow-calf performance and overall farm financial outcomes ...

Galactokinase 1 Positively Regulates Mitochondrial Respiration by Phosphorylating TIMM13 as a Protein Kinase

Advanced Science, EarlyView.
GALK1 acts as a protein kinase beyond the phosphorylation of galactose. GALK1 phosphorylates TIMM13 at Y73 in the cytoplasm. This phosphorylation prevents premature oxidative folding of TIMM13 and ensures its entrance into the intermembrane space of mitochondrion, positively regulating mitochondrial respiration.

Oral Astilbin Nanogels Modulate Senescence‐Associated CD4+ T Cells and Promote Treg Induction in Aged Mice with Colitis

Advanced Science, EarlyView.
Fluorinated β‐glucan/pectin nanogels enable colon‐targeted oral delivery of astilbin through gastrointestinal protection, β‐glucanase‐responsive release, mucus penetration, and prolonged retention. The released astilbin attenuates senescence‐associated features of CD4+ T cells and promotes Treg responses, while the nanogel matrix modulates the gut ...

Cow-Calf Producer Interest in Retained Ownership [PDF]

The beef industry’s share of domestic meat demand continues to decline, as increasing vertical coordination in pork and poultry contribute to these industries’ ability to offer convenient, consistent, and less expensive products.

A Dual‐Functional Nanoplatform Targeting the dsDNA–cGAS Axis to Mitigate Disc Degeneration and Aberrant Innervation

Advanced Science, EarlyView.
RU@PEI‐ZIF integrates dsDNA scavenging with local cGAS inhibition to suppress the dsDNA–cGAS–STING/Netrin‐1 axis in intervertebral disc degeneration. By attenuating nucleus pulposus cell senescence, inflammatory and matrix‐catabolic responses, and pathological sensory innervation, this dual‐functional nanoplatform preserves disc integrity and reduces ...

The Economics of Organic Versus Conventional Cow-calf Production [PDF]

Costs, returns, and profitability of cow-calf farms that are organic or transitioning to organic are compared with those of cow-calf farms that are non-organic. A method of matching samples is used for the comparison.
