Wirelessly Powered Soft Magnetic Robot with Microneedle for Electrical Stimulation and Drug Delivery

open access: yesAdvanced Intelligent Systems, EarlyView.
A wirelessly powered soft magnetic robot integrates microneedles to enable dual functions: electrical stimulation (86.7% efficiency at 6 cm, tunable 0–20 V voltage, 0.4–50 ms pulses) and drug delivery. It switches surfaces via magnetic fields for gastrointestinal tract locomotion and treatment, with in vitro validation in fresh pig gut showing ...

Development of an in situ small intestinal injection technique for targeted macromolecule delivery and in vivo functional studies in mice

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This study developed a minimally invasive, in situ small intestinal injection technique for mice, enabling targeted delivery of bioactive molecules while bypassing gastric degradation. Validation using functional assays and single‐cell RNA sequencing reveals high‐mobility group box 1–mediated epithelial responses, offering a translational tool for gut ...

Changes in Tight Junction Protein Expression Levels but Not Distribution in Commercial White and Brown Laying Hens Supplemented with Chondrus crispus or Ascophyllum nodosum Seaweed

open access: yesAnimals
It is proposed that prebiotic diet supplements improve intestinal function, in part by improving the barrier function of the intestinal epithelium with an associated increase in the expression of tight junction proteins, including occludin and zonula ...

Intestinal gene expression in pigs: effects of reduced feed intake during weaning and potential impact of dietary components [PDF]

open access: yes, 2011
The weaning transition is characterised by morphological, histological and microbial changes, often leading to weaning-associated disorders. These intestinal changes can partly be ascribed to the lack of luminal nutrition arising from the reduced feed ...

A contribution to the anatomy of two rare cetacean species: The hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica)

open access: yesThe Anatomical Record, EarlyView.
Abstract The anatomical description of the hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica) remains largely unexplored, due to limited specimen availability and preservation challenges. This study employed digital imaging techniques, conventional histology, and computed tomography to provide visualization of

Reduction in jejunal fluid absorption in vivo through distension and cholinergic stimulation not attributable to enterocyte secretion [PDF]

open access: yes, 2018
Jejunal fluid absorption in vivo was reduced by distension and by hydrostatic pressure and further declined on adding E. coli STa enterotoxin but no net fluid secretion was detected.

Effects of Dietary Protein Level on Growth Performance, Serum Biochemistry, Intestinal Morphology, and Intestinal Microbiota in Ningxiang Finishing Pigs

open access: yesAnimal Research and One Health, EarlyView.
A low‐protein (LP) diet maintained growth performance while enhancing colonic microbiota composition and nitrogen utilization in Ningxiang finishing pigs. These findings enhance our understanding of protein nutrition in indigenous fat‐type pig breeds and provide a theoretical foundation for optimizing dietary formulations in Ningxiang pigs.
