Acute respiratory failure (ARF) occurs in less than 0.1% of pregnancies; however, it is one of the most common reasons for obstetric admissions to the intensive care unit (ICU) and carries a high mortality for both mother and fetus. Pulmonary physiological and anatomic adaptations during pregnancy affect the overall management, as well as predispose patients to complications during respiratory ...

The ability of rat small intestine to chain-shorten C22:1 fatty acids was investigated. Radioactive chain-shortened products, mainly C18:1, were demonstrated in intestinal-lymph lipids after intraluminal injection of [14-14C]erucic acid. Chain-elongation to C24:1 was also observed. Adaptation to a diet containing C22:1 fatty acids (partially hydrogenated-marine-oil diet) slightly increased the ...

BACKGROUND Epidermal growth factor (EGF) and transforming growth factor-alpha (TGF alpha) are potent gastric acid inhibitors and stimuli of mucosal growth and protection but their involvement in Helicobacter pylori associated duodenal ulcer has been little examined. AIM To assess gastric acid secretion, plasma gastrin concentrations, mucosal content of EGF and TGF alpha, and mucosal expressio...

Epidemiological and animal studies suggest a role for calcium in the chemoprevention of colorectal neoplasia. This study was designed to investigate whether supplemental oral calcium has a suppressant effect on colonic mucosal ornithine decarboxylase (ODC) and tyrosine kinase activities in patients with adenomatous polyps or a history of adenomatous polyps and whether this is affected by age. O...

Vertical level difference due to vertical angular asymmetry (up 20°) between the normal (right) and tilted (left) vocal fold (VF) is experimentally assessed in framework of unilateral paralysis. The upstream pressure high-speed vibration imaging for different camera view angles are during steady-state auto-oscillation three mechanical VF replicas. A global image-based correlation allows assess ...

The objective of this study was to highlight the postnatal development of the uterine tubes of the West African Dwarf goat from birth to 28 weeks of age by gross examination and light microscopy. There was a caudal migration of the paired uterine tubes from behind the paired kidneys at birth to the pelvic inlet at week 8 of age. Each uterine tube exhibited three segments namely; infundibulum, a...

Alcohol disrupts the intestinal mucosal barrier by inducing metabolic and functional changes in epithelial cells. Recently, we showed that neuropeptide S (NPS) decreases duodenal motility and increases mucosal paracellular permeability, suggesting a role of NPS in the pathogenesis of disorders and dysfunctions in the small intestine. The aim of the present study was to investigate the effects o...

BACKGROUND Intestinal adaptation after massive bowel resection in animal models is characterized by increased gut-mucosal growth and expression of nutrient transporters. Few data about these indexes exist in humans with short-bowel syndrome (SBS). OBJECTIVE The objective was to compare small-bowel and colonic mucosal growth and expression of the peptide transporter PepT1 in adults with or wit...
