36 results about "Intestinal villus" patented technology

Intestinal villi (singular: villus) are small, finger-like projections that extend into the lumen of the small intestine. Each villus is approximately 0.5–1.6 mm in length (in humans), and has many microvilli projecting from the enterocytes of its epithelium which collectively form the striated or brush border. Each of these microvilli are much smaller than a single villus. The intestinal villi are much smaller than any of the circular folds in the intestine.

Application of pyrrosia lingua aqueous extract in preparation of medicine for preventing and treating radioactive intestinal injury

The invention discloses an application of a pyrrosia lingua aqueous extract in preparation of a medicine for preventing and treating radioactive intestinal injury. Radioactive intestinal injury is a common complication of ionizing radiation, and has main pathological characteristics of intestinal mucosal barrier destruction, excessive release of inflammatory factors, increase of oxidative stress level and hematopoiesis and immune function inhibition. At present, no effective and safe prevention and treatment medicine is available. It is found for the first time that the pyrrosia lingua aqueous extract can inhibit expression (IL-6, TNF-alpha and IL-1beta) of inflammatory factors of radiation-induced MODE-K cells and relieve the oxidative stress level (malondialdehyde (MDA) is reduced, and the content of superoxide dismutase (SOD) and glutathione (GSH) is increased). In animal experiments, the pyrrosia lingua aqueous extract can reduce the levels of TNF-alpha and IL-1beta inflammatory factors in serum of irradiated mice and improve oxidative stress disorders such as MDA increase, SOD and GSH decrease and the like; the reduction of leukocytes and lymphocytes is relieved; the length of intestinal villus is promoted and recovered; the proportion of Ki67 positive cells in a crypt region is increased, so that the regeneration capacity of intestinal epithelial cells is enhanced. The pyrrosia lingua aqueous extract disclosed by the invention provides an experimental basis and an application prospect for developing a novel medicine for preventing and treating the radioactive intestinal injury.

PendingUS20250387359A1Organic chemistryAerosol deliveryBiotechnologyIntestinal villous atrophy
Cryptosporidium parvum is a highly prevalent zoonotic and anthroponotic protozoan parasite that causes a diarrheal syndrome in children and neonatal livestock, culminating in growth retardation and mortalities. Disclosed herein are inhibitors against the enzymatic activity of recombinant CpLDH protein that were identified. The inhibitors were tested for anti-Cryptosporidium effect using in vitro infection assays of HCT-8 cells monolayers. Compounds NSC158011 and NSC10447 were identified to inhibit the proliferation of intracellular C. parvum in vitro, with IC50 values of 14.88 and 72.65 μM, respectively. At doses tolerable in mice, both NSC158011 and NSC10447 significantly reduced the shedding of C. parvum oocysts in infected immunocompromised mice's feces and prevented intestinal villous atrophy as well as mucosal erosion due to C. parvum. These findings have unveiled anti-Cryptosporidium drug candidates that can be explored further for the development of therapeutic agents against C. parvum infections.

A feed additive that promotes digestion and absorption and its preparation process

This invention relates to the field of feed additive technology, specifically to a feed additive that promotes digestion and absorption and its preparation process. The preparation process of a feed additive that promotes digestion and absorption includes: preparing antioxidant-modified chicken fat; preparing an extract; preparing a composite oil phase; and preparing the feed additive. In this invention, the extract of Shenqu (a type of fermented wheat) can directly compensate for insufficient endogenous enzyme secretion in laying hens, rapidly decomposing starch in feed and chicken fat in plant proteins, laying the foundation for subsequent absorption. The extract of Zhishi (a type of immature bitter orange) accelerates gastrointestinal motility and digesta emptying, while also promoting bile and pancreatic juice secretion, further improving the digestibility and utilization rate of fat-soluble components in laying hens. The extract of pine pollen can repair the intestinal mucosa, increase intestinal villus height, increase the nutrient absorption area, and regulate the intestinal microecology, reducing nutrient loss and intestinal stress. The combined use of these three ingredients synergistically promotes the digestive and absorptive capacity of laying hens.
