BACKGROUND: Leak rates of over 5% following anastomoses between the ileum and colon continue to be reported in large series and are associated with substantial morbidity and with mortality rates of 10-20%. In 1994, we began performing circumferentially oversewn inverted stapled anastomoses in patients undergoing ileo-colic anastomoses or ileostomy closure. It has become increasingly apparent that this method is associated with a low risk of leakage, which we should report. METHODS: The anastomotic technique described was used in all patients undergoing ileo-colic anastomosis or closure of ileostomy by surgeon 1 (1994-2015) and in all ileo-colic anastomoses by surgeon 2 (2007-2015)...

BACKGROUND: To determine the minimum survival benefits that patients, and their clinicians, judged sufficient to make adjuvant chemotherapy (ACT) worthwhile, in addition to pelvic radiotherapy, for women with high risk and advanced stage endometrial cancer. METHODS: Eighty-three participants in the PORTEC-3 trial completed a time trade-off questionnaire before and after adjuvant therapy; 44 of their clinicians completed it once only. The questionnaire used four hypothetical scenarios including baseline survival times without ACT of 5 and 8 years, and baseline survival rates at 5 years without ACT of 50 and 65%...

MicorRNA-137 is silenced in human colorectal cancer tissues and colon polyps. Our study showed that the decreased expression of miR-137 is significantly different in various types of polyp which maintain different potentials to lead to CRC development. The expression of miR-137 gradually decreases during the process of colorectal carcinogenesis. Receiver operating characteristic curve (ROC) analysis indicates that the loss of miR-137 expression in colon polyps can serve as a biomarker to predict the predisposition of colorectal carcinogenesis...

INTRODUCTION: It is important to understand the drivers leading to adaptive phenotypic diversity within and among species. The threespine stickleback (Gasterosteus aculeatus) has become a model system for investigating the genetic and phenotypic responses during repeated colonization of fresh waters from the original marine habitat. During the freshwater colonization process there has been a recurrent and parallel reduction in the number of lateral bone plates, making it a suitable system for studying adaptability and parallel evolution...

CONTEXT: -CDH17, which is expressed in the intestinal epithelium, is a novel oncogene involved in tumor invasion and metastasis. A panel consisting of cytokeratin (CK) 7, CD20, and CDX2 antibodies is typically used to diagnose gastrointestinal adenocarcinomas. However, studies have shown that CDH17 is a highly specific marker for gastrointestinal adenocarcinoma and may be important in clinical diagnosis. OBJECTIVE: -To evaluate the sensitivity and specificity of CDH17, CK20, and CDX2 antibodies in neoplastic tissues, with emphasis on colon, stomach, and esophageal gastrointestinal lineage...

Dentatin (DEN), purified from the roots of Clausena excavata Burm f., has poor aqueous solubility that reduces its therapeutic application. The aim of this study was to assess the effects of DEN-HPβCD (hydroxypropyl-β-cyclodextrin) complex as an anticancer agent in HT29 cancer cell line and compare with a crystal DEN in dimethyl sulfoxide (DMSO). The exposure of the cancer cells to DEN or DEN-HPβCD complex leads to cell growth inhibition as determined by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay...

In the early 1900s, an obscure Portuguese colony in the equatorial Atlantic rose as the world's leading cocoa producer. Cocoa from the island of São Tomé was grown on large plantations with indentured labor and high technological inputs. This technoscientific system, to control both plants and people, became the model for making an industry-suited cocoa, and the material evidence of the moral and economic virtues of the colonial plantation. Experts played a crucial role in building and putting into circulation such a system...

BACKGROUND: Neutrophil function is critical for the initiation and progression of infecto-inflammatory diseases. Key quorum-sensing plaque bacteria such as Fusobacterium nucleatum act as bridging species between early and late colonizer pathogens such as Porphyromonas gingivalis as the biofilm ages and periodontal inflammation increases. This study was designed to determine the impact of different F. nucleatum strains on neutrophil function. MATERIALS AND METHODS: HL-60 cells were differentiated into neutrophil-like cells and cultured with F...

A rare chemotaxis receptor, Tlp11, has been previously identified in invasive strains of Campylobacter jejuni, the most prevalent cause of bacterial gastroenteritis worldwide. Here we use glycan and small-molecule arrays, as well as surface plasmon resonance, to show that Tlp11 specifically interacts with galactose. Tlp11 is required for the chemotactic response of C. jejuni to galactose, as shown using wild type, allelic inactivation and addition mutants. The inactivated mutant displays reduced virulence in vivo, in a model of chicken colonization...

The development of colonic diverticula is common in developed countries and complications of colonic diverticulosis are responsible for a remarkable burden of the disease. The natural history and management of complicated and recurrent diverticulitis in young patients are still a matter of debate. Coloenteric fistula is a rare complication of diverticulitis in young adults. In this report, and utilising a case study, we will review the natural history, outcome and management of acute diverticulitis in the young...

Wnt5b, a member of the same family of proteins as Wnt5a of which overexpression is associated with cancer aggressiveness, is suggested to be involved in cancer progression, however details remain unclarified. We analyzed biochemical properties of purified Wnt5b and the mode of secretion of Wnt5b by cancer cells. Wnt5b was glycosylated at three asparagine residues and lipidated at one serine residue, and these post-translational modifications of Wnt5b are essential for secretion. Purified Wnt5b showed Dvl2 phosphorylation and Rac activation abilities to a similar extent as Wnt5a...

AIMS: Diet-derived short chain fatty acids (SCFAs) improve glucose homeostasis in vivo, but the role of individual SCFAs and their mechanisms of action have not been defined. This study evaluated the effects of increasing colonic delivery of the SCFA propionate on β-cell function in humans and the direct effects of propionate on isolated human islets in vitro. MATERIALS AND METHODS: For 24 weeks human subjects ingested an inulin-propionate ester that delivers propionate to the colon...

We previously reported that celecoxib, a selective cyclooxygenase-2 (COX-2) inhibitor, strongly inhibited human colon cancer cell proliferation by suppressing the Wnt/β-catenin signaling pathway. 2,5-Dimethylcelecoxib (DM-celecoxib), a celecoxib analogue, which does not inhibit COX-2, has also been reported to have an anti-tumor effect. In the present study, we elucidated whether DM-celecoxib inhibits intestinal cancer growth, and its underlying mechanism of action. First, we compared the effect of DM-celecoxib with that of celecoxib on the human colon cancer cell lines HCT-116 and DLD-1...

Whooping cough (pertussis) is a highly contagious respiratory infection caused by Bordetella pertussis. Although availability of effective pertussis vaccines seems to decrease the incidence of the disease, B. pertussis circulation in population has not been eliminated. Thus, finding new protein candidates with high immune protective capacities is necessary to enhance the efficacy of current acellular pertussis (Pa) vaccines. In this study, iron superoxide dismutase (FeSOD) gene (sodB) was cloned, expressed in Escherichia coli and recombinant FeSOD protein was purified...

According to the hygiene hypothesis, insufficient immune activation by microbes increases the risk of allergy development. Staphylococcus aureus, which is part of the skin and gut microbiota of infants in Western countries, produces a variety of T-cell-activating enterotoxins, called superantigens. We investigated whether early (0-2 months of age) gut colonisation by S. aureus strains that carry specific superantigens and adhesins was related to subsequent development of atopic eczema in a Swedish birth-cohort...

The human gastrointestinal tract is the primary site of colonization of multidrug resistant pathogens and the major source of life-threatening complications in critically ill and immunocompromised patients. Eradication measures using antibiotics carry further risk of antibiotic resistance. Furthermore, antibiotic treatment can adversely shift the intestinal microbiome toward domination by resistant pathogens. Therefore, approaches directed to prevent replacement of health promoting microbiota with resistant pathogens should be developed...
