BACKGROUND: Oral cavity cancers are fairly common and have propensity to recur locally. Since Pectoralis Major Myocutaneous (PMMC) flap is the most widely used first flap for reconstruction, it is exhausted at the earliest and recurrence poses a formidable challenge for reconstructive surgeon. Present study evaluated the feasibility of contralateral Pectoralis Major Myocutaneous Flap for reconstruction after resection of recurrent tumour. METHODS: This was a study of the patients presenting with recurrent oral cavity cancer after exhausted ipsilateral Pectoralis Major Myocutaneous Flap (PMMC) in whom we used contralateral Pectoralis Major Myocutaneous Flap (Crossed PMMC Flap) for reconstruction between October 2013 to June 2016...

Species of Amphiuma enter a state of subterranean estivation with the drying of their aquatic habitat. Characteristic of amphibian fasting and estivation is an initial depression of metabolism and tissue mass and function with fasting, followed by a more pronounced adaptive decrease in metabolism and tissue function with estivation. We hypothesized that Amphiuma likewise experiences a two-stage set of responses to estivation. Therefore, we examined the physiological responses of the three-toed amphiuma (Amphiuma tridactylum) to fasting and estivation treatments...

An 84-year-old man was referred to our hospital because of watery diarrhea. Due to cerebral infarction, he had started treatment with a novel oral anticoagulants (NOAC) 1 month prior to admission. The patient underwent blood tests, enhanced computed tomography, and colonoscopy, which indicated infectious or medicinal colitis. The diarrhea persisted and he developed hypokalemia, so a second colonoscopy was performed, which showed edematous mucosa. Colonic mucosal biopsies showed a thick collagen band in the subepithelial region, and collagenous colitis was diagnosed...

The strong age dependency of neonatal systemic infection with Escherichia coli K1 can be replicated in the neonatal rat. Gastrointestinal (GI) colonization of two-day-old (P2) rats leads to invasion of the blood within 48 h of initiation of colonization; pups become progressively less susceptible to infection over the P2-P9 period. We show that, in animals colonized at P2 but not at P9, E. coli K1 bacteria gain access to the enterocyte surface in the mid-region of the small intestine and translocate through the epithelial cell monolayer by an intracellular pathway to the submucosa...

Gut barrier function is key in maintaining a balanced response between the host and its microbiome. The microbiota can modulate changes in gut barrier as well as metabolic and inflammatory responses. This highly complex system involves numerous microbiota-derived factors. The gut symbiont Akkermansia muciniphila is positively correlated with a lean phenotype, reduced body weight gain, amelioration of metabolic responses and restoration of gut barrier function by modulation of mucus layer thickness. However, the molecular mechanisms behind its metabolic and immunological regulatory properties are unexplored...

BACKGROUND/AIM: Diagnosis of Hirschsprung's disease (HD) can be hard and requires good experience, principally for pathologists who infrequently encounter the disease. However, diagnosis is not always possible with hematoxylin and eosin (H and E) because staining has limitations in the identification of immature ganglion cells in neonates and the submucosal area. AIM: To assess the diagnostic role of calretinin immunostaining in HD in comparison to neuron-specific enolase...

Rectal enemas that contain prophylactic levels of anti-HIV microbicides such as tenofovir have emerged as a promising dosage form to prevent sexually transmitted HIV infections. The enema vehicle is promising due to its likely ability to deliver a large amount of drug along the length of the rectal canal. Computational models of microbicide drug delivery by enemas can help their design process by determining key factors governing drug transport and, more specifically, the time history and degree of protection...

The endoscopic treatment of early gastrointestinal neoplasms usually involves the resection of the superficial layers, mucosa and submucosa, of the wall. However, in some circumstances, a full-thickness resection may be necessary. Endoscopic full-thickness resection (EFTR) may be an adequate approach in challenging lesions such as adenomas or early cancers with severe submucosal fibrosis or small sub-epithelial lesions in the lower GI tract. Furthermore, this novel technique has the potential to spare surgical therapy in a subset of cases...
