Matrix-assisted laser desorption/ionization imaging mass spectrometry (MALDI-IMS) enables acquisition of spatial distribution maps for molecular species in situ. This can provide comprehensive ...

Background: Exogenous use of the intestinal hormone glucagon-like peptide 1 (GLP-1) lowers glycaemia by stimulation of insulin, inhibition of glucagon, and delay of gastric emptying. Aims: To assess ...

Design Rats intraperitoneally injected with AFS cells and their controls (bone marrow mesenchymal stem cells, myoblast) were analysed for survival, behaviour, bowel imaging (MRI scan), histology, ...

Anatomy of the pancreas The pancreas is an elongated, tapered organ located across the back of the belly, behind the stomach. The right side of the organ—called the head—is the widest part of the ...

Inconsistencies in the preparation of histology slides make it difficult to perform quantitative analysis on their results. In this paper we provide two mechanisms for overcoming many of the known ...

Small intestine articles from across Nature Portfolio Atom RSS Feed The small intestine is located between the stomach and the large intestine and is composed of the duodenum, jejunum and ileum ...

The intestine is one of the most versatile epithelia in our body; it is involved in many physiological processes, including nutrient uptake as well as immune modulation and displays the interface to a ...

Esophagus, stomach, and proximal duodenal mucosa were examined under sedation or general anesthesia. Six biopsies of the gastric mucosa: two from gastric corpus (lesser and greater curvature), two ...

Weakly-supervised learning (WSL) has recently triggered substantial interest as it mitigates the lack of pixel-wise annotations. Given global image labels, WSL methods yield pixel-level predictions ...

The endoscope transmits an image of the esophagus, stomach and duodenum to a monitor that your physician is watching. Biopsy forceps will be inserted into the endoscope to remove a tissue sample. An ...

This study aimed to obtain information on the transport form and pathway from the intestine to the peripheral tissues and on the intestinal absorption and metabolism properties of oleamide ...
