Weaning is essential for foal growth and development. We determined the intestinal flora structure of donkey foals at the end of weaning (PreW_4d) and three stages after weaning (PostW_4d, PostW_8d, and PostW_15d) to explore the effects of weaning on intestinal development of donkey foals. The results showed that the main microbial flora in the gut of the donkey foal were Firmicutes and Bacteroides, and the proportion of Firmicutes gradually increased with weaning, which was an important reflection of the donkey foal's adaptability to the transition from lactose liquid feed to plant fiber solid feed.

Children with neurodegenerative disease often have debilitating gastrointestinal symptoms. We hypothesized that this may be due at least in part to underappreciated degeneration of neurons in the enteric nervous system (ENS), the master regulator of bowel function. To test this hypothesis, we evaluated mouse models of neuronal ceroid lipofuscinosis type 1 and 2 (CLN1 and CLN2 disease, respectively), neurodegenerative lysosomal storage disorders caused by deficiencies in palmitoyl protein thioesterase-1 and tripeptidyl peptidase-1, respectively.

In recent years, nano and micro drug delivery systems targeting the colon have gained more attention due to increasing interest in treating colon diseases such as colorectal cancer and inflammatory bowel disease, , Crohn's disease and ulcerative colitis. Usually, nanocarriers are exploited for their enhanced permeability properties, allowing higher penetration effects and bioavailability, while microcarriers are primarily used for localized and sustained release. In bowel diseases, carriers must go into a delicate environment with a strict balance of gut bacteria (, colon), and natural or biodegradable polymers capable of ensuring lower toxicity are preferred.

Colon cancer is a leading cause of cancer-related morbidity and mortality worldwide, necessitating advancements in therapeutic strategies to improve outcomes. Current treatment modalities, including surgery, chemotherapy, and radiation, are limited by systemic toxicity, low drug utilization rates, and off-target effects. Colon-targeted drug delivery systems (CDDS) offer a promising alternative by leveraging the colon's unique physiology, such as near-neutral pH and extended transit time, to achieve localized and controlled drug release.

Background: The relationship between gut microbiota composition, lifestyles, and colonic transit time (CTT) remains poorly understood. This study investigated associations among gut microbiota profiles, diet, lifestyles, and CTT in individuals with subjective constipation.
Methods: We conducted a secondary analysis of data from our randomized clinical trial, examining gut microbiota composition, CTT, and dietary intake in baseline and final assessments of 94 participants with subjective constipation.
