Alterations in histomorphological features of the pelvic ureter such as muscle fiber orientation have been implicated in the etiology of vesicoureteric reflux. Consequently, anatomical sex differences in the histomorphology of the pelvic ureter may explain the female predisposition to this disease. Reports of these differences are, however, scarce. Twelve adult pelvic ureters (6 male and 6 fema...

1. To study the relative contributions of luminal nutrition, bile and pancreatic secretions and hormonal factors in intestinal adaptation, lactation hyperphagia was chosen as a model for increased luminal nutrition, either alone (intestinal transection control group) or in combination with (i) exclusion of bile and pancreatic secretions from the jejunum (by transposition of the jejunum above th...

INTRODUCTION Sarcomatoid carcinoma (SCA) of jejunum is an extremely rare condition. To our knowledge, only 17 cases have been reported in the literature. PRESENTATION We introduced an additional case of the sarcomatoid carcinoma of jejunum in a 62-year-old Chinese male who presented with epigastric pain for 3 weeks. Multiple tumors originated in the jejunum and metastases to mesentery lymph n...

This study aimed to investigate the usefulness of intraluminal PCO2 (PiCO2) monitoring by air tonometry for the assessment of the vascular condition of the transferred jejunum after surgery for hypopharyngeal cancer.PiCO2 in the transplanted jejunum of 24 patients was monitored using air tonometry after radical surgery for hypopharyngeal cancer from 2003 to 2010.All but 1 patient, who removed t...

1. To study further the influence of luminal nutrition on small bowel structure and function, segments of rat jejunum and ileum were completely excluded from intestinal continuity by Thiry-Vella by-pass operations. The effect of partial deprivation of luminal nutrition was also studied in jejunal segments that had been surgically transposed to a distal position in the intestinal tract. 2. Macro...

Effects of feeding dietary defatted black soldier fly ( Hermetia illucens ) larvae meal (HI) on intestine microbiota, and histomorphology, oxidative enzyme activities in liver pikeperch Sander lucioperca were investigated. Four isoproteic (45% crude protein) isolipidic (18% ether extract) diets formulated to include 0% (CO), 9% (HI9), 18% (HI18) 36% (HI36) HI as replacement for fishmeal at 0, 2...

Using mice deficient in hepatic cytochrome P-450 oxidoreductase (POR), which disables the liver cytochrome P-450 system, we examined the metabolism and biological response of the anticarcinogenic flavonoid, quercetin. Profiling circulating metabolites revealed similar profiles over 72 h in wild-type (WT) and POR-null (KO) mice, showing that hepatic P450 and reduced biliary secretion do not affe...

Intestinal monosaccharide transport was studied in a series of rats with a self-filling jejunal blind loop using 3mM arbutin (p-hydroxyphenyl-B-glucoside) or 1mM D-fructose as substrate in vitro and 10 mM arbutin or 5mM D-fructose in vivo. These results were compared with changes in the bacterial flora and state of conjugation of intraluminal bile salts in those animals. Observations were also ...
