Growth alterations within the gastric mucosa during chronic gastric inflammation are key steps in gastric cancer development. FGF7, a specific mitogen for epithelial cells, is implicated in epithelial tissue repair and cancer. We investigated FGF7 expression in normal human stomach, and in 35 cases from various gastric pathologies including 23 gastritis and 8 adenocarcinoma cases.

There is evidence to suggest that apoptosis in the contralateral testis is involved in germ cell loss following IR injury to the testis. We examined the time-dependent effect of testicular ischemia on germ cell apoptosis in the contralateral testis in a rat.

Also, a resected polyp may be lost at any step between its endoscopic removal and its embedding in paraffin. The aim of this study was to compare the histological features of colonic polyps as analysed by the study of biopsy-forceps obtained samples with those assessed on scrutinizing the totally resected growths.

It is also well known that the route of administration modulates the effects of ARG. The present study evaluated the effects of parenteral ARG on structural intestinal adaptation, cell proliferation, and apoptosis in a rat model of short bowel syndrome (SBS).

The purpose of the present study was to evaluate the effects of high-fat diet (HFD) on early intestinal adaptation in rats with short bowel syndrome (SBS). Male Sprague-Dawley rats underwent either a bowel transection with re-anastomosis (Sham rats) or 75% small bowel resection (SBS rats).

As part of a population-based case-control study of colorectal cancer in northern Israel, we reviewed the pathology and microsatellite status of 528 consecutively diagnosed colorectal cancers. Phenotypic analysis was performed by one pathologist (J.

Objective: The propagation speed of ultrasound beams changes in different media. The aim of the study was to assess the possible measurement error of fetal biometry performed in cases of a myomatous uterus.
Design: Three iron phantoms of 30 mm, 50 mm and 70 mm were measured by ultrasound.
Objective: To evaluate the prognostic significance of vimentin intermediary filament expression by tumour cells in patients with renal cell carcinoma (RCC) localized to the kidney.
Patients And Methods: Thirty-nine patients with localized RCC (pT1,pT2) were assessed in a retrospective study. Tumour cells were evaluated immunohistochemically for vimentin, epithelial membrane antigen (EMA) and polyclonal cytokeratin expression.
We report a case of radiation-induced retroperitoneal leiomyosarcoma which developed 37 years after the patient received radiation therapy for testicular seminoma. The sarcoma originated within the para-aortic field, extensively involving neighboring organs, soft tissue and muscle tissues, and could be only partially resected. The absolute number of these secondary sarcomas is low, but the risk of developing such neoplasms calls for awareness in the long-term follow-up of cured seminoma patients.

Patients And Methods: A retrospective prognostic study of 39 patients with localized (pT1, pT2) RCC was performed. Conventional histological grade and nuclear morphometry were assessed independently and the correlation between these grading systems and their impact on the patients' outcome were evaluated.

A 12-year-old boy, operated on for remitting abdominal pain and hematochezia, had an ileal duplication, with Helicobacter "gastritis" under a chronic peptic ulcer in the ectopic fundic gastric mucosa. We suggest the Helicobacter infection might have played a role in the pathogenesis of the inflammation and the peptic ulceration in this rare location.
View Article and Find Full Text PDFA case of eosinophilic fasciitis (EF), associated with monoclonal gammopathy, thyroglobulin antibodies, pericarditis and colitis, is described. The occurrence of EF in the framework of a multisystem disease is the outstanding feature, contrasting with the absence of visceral involvement or solitary organ involvement in the large majority of cases. The unusual histologic features of the colitis and beneficial effect of cimetidine on EF are discussed.
