Abstract
Background Numerous patients with inflammatory bowel disease (IBD) do not respond to conventional or biological therapy. Adalimumab (ADA) and vedolizumab (VDZ), according to certain research, may be a useful alternative treatment for these people. The purpose of this study was to assess the effectiveness and safety of using ADA and VDZ to treat moderate to severe IBD: Crohn's disease (CD) and ulcerative colitis (UC). Methods We searched PubMed, Medline, Web of Science, Scopus, the Cochrane Library, Embase, Google Scholar, CINAHL, Clinicaltrials.gov, and WHO trials registry (ICTRP). Randomized controlled trials (RCTs) comparing ADA or VDZ with placebo in participants with active CD or UC were included. The primary outcomes were the clinical response and remission at induction and maintenance phases and mucosal healing. The secondary outcome was the incidence of profound negative events. The research used Comprehensive Meta-Analysis version 3 (Biostat Inc., USA). Results Eighteen RCTs were incorporated, in which 11 studies described the usefulness and safeness of ADA or VDZ in CD patients, and seven studies investigated the efficacy and safety of ADA or VDZ in UC patients. The meta-analysis revealed that both ADA and VDZ treatments were superior to placebo for producing clinical remission and eliciting clinical response at induction and maintenance phases in individuals with moderately to severely active CD or UC. Interestingly, we found that ADA was superior to VDZ as first-line treatment for patients with CD, but not UC. Conclusion ADA and VDZ are effective and safe in CD and UC patients. However, RCTs of a larger number of patients are still required for better assessing the safety profile of ADA and VDZ.

Abstract
BACKGROUND AND AIMS Cold snare resection of colorectal lesions has been found to be safe and effective for an expanding set of colorectal lesions. In this study, we sought to understand the efficacy of simple cold snare resection and cold EMR versus hot snare resection and hot EMR for colorectal lesions 6 to 15 mm in size. METHODS At 3 U.S. centers, 235 patients with 286 colorectal lesions 6 to 15 mm in size were randomized to cold snaring, cold EMR, hot snaring, or hot EMR for nonpedunculated colorectal lesions 6 to 15 mm in size. The primary outcome was complete resection determined by 4 biopsy samples from the defect margin and 1 biopsy sample from the center of the resection defect. RESULTS The overall incomplete resection rate was 2.4% (95% confidence interval [CI], .8%-7.5%). All 7 incompletely removed polyps were 10 to 15 mm in size and removed by hot EMR (n = 4, 6.2%), hot snare (n = 2, 2.2%), or cold EMR (n = 1, 1.8%). Cold snaring had no incomplete resections, required less procedural time than the other methods, and was not associated with serious adverse events. CONCLUSIONS Cold snaring is a dominant resection technique for nonpedunculated colorectal lesions 6 to 15 mm in size. (Clinical trial registration number: NCT03462706.).

Abstract
To date, the survival of Escherichia coli O157:H7 and other verocytotoxin-producing E. coli (VTEC) in chocolate and other confectionery products has not been fully established, unlike Salmonella, which have been responsible for occasional outbreaks of infection linked to contaminated chocolate and related products, although none of these outbreaks have been related to products produced in the United Kingdom. The United Kingdom Biscuit, Cake, Chocolate and Confectionery Alliance commissioned this study to obtain information on the decline and potential survival of E. coli, particularly verocytotoxin-producing strains, in reduced aw confectionery products chocolate, biscuit cream and mallow. These products were artificially contaminated with high (4 log10 cfu/g) and low (2 log10 cfu/g) levels of E. coli O157:H7, O111:H- and O26:H11 and their survival, as affected by storage temperature (10, 22 and 38 degrees C), was monitored over 12 months. Preliminary studies to establish the best inoculation and recovery procedures indicated that differences between counts on selective and non-selective media used were not sufficiently different to influence the outcome of this study. Irrespective of sample type, rapid decline was observed in products stored at 38 degrees C and increased survival occurred in products stored at 10 degrees C. In chocolate (average aw 0.40), these bacteria were detected for up to 43 days in samples stored at 38 degrees C. At 22 degrees C they survived for up to 90 days and in product stored at 10 degrees C they could still be detected after 366 days storage. In biscuit cream (average aw 0.75) they survived for 2 days at 38 degrees C, 42 days at 22 degrees C and 58 days at 10 degrees C. Whilst mallow (aw ca. 0.73) was not stored at 38 degrees C, these bacteria could still be detected in samples stored for up to 113 and 273 days at 22 and 10 degrees C, respectively. The observed prolonged survival of these bacteria under conditions of reduced aw and lowered storage temperature in this study is supported by previous studies with Salmonella and E. coli O157:H7 in other foods. In the same way that Salmonella bacteria can survive for long periods, in excess of 12 months, in chocolate, this study provides evidence that E. coli, including pathogenic strains, can also survive for similar periods of time. Assuming the routes of transmission are similar, controls currently used by the confectionery industry to prevent contamination by Salmonella should also be effective against E. coli, including VT-producing strains, providing that all raw materials have been suitably processed, stored and handled before and during manufacture.

Abstract
A novel low mol wt inositol phosphoglycan antagonist of insulin action of oxidative glucose metabolism in isolated rat adipocytes was partially purified from normal human plasma and shown to be increased in type II diabetic plasma. It was characterized chemically as a myo-inositol phosphoglycan containing a cyclic 1,2-phosphate. This antagonist, termed fraction V3, is now shown to inhibit the action of an inositol glycan insulin pH 2.0 mediator that stimulates pyruvate dehydrogenase phosphatase in a similar manner to insulin. In addition, fraction V3 inhibits stimulation of the pyruvate dehydrogenase (PDH) phosphatase by Mg2+, the enzyme's required metal, and by spermine, a polyamine. Fraction V3 does not inhibit active PDH itself. The inhibitory effect is dose dependent and apparently noncompetitive or nonsurmountable for the insulin inositol glycan pH 2.0 mediator, thus comparing kinetically with its insulin antagonistic action on intact adipocytes. Its inhibitory action on PDH phosphatase is dose dependent and competitive for Mg2+ stimulation of the phosphatase. Additionally, fraction V3 is shown to inhibit stimulation by Mg2+ of cloned recombinant PDH phosphatase catalytic subunit. Inhibition by fraction V3 of Mg(2+)-stimulated PDH phosphatase and its cloned catalytic subunit helps explain its mechanism of action to inhibit insulin-stimulated oxidative glucose metabolism in adipocytes and its potential clinical significance in insulin resistance.

Abstract
Using five monoclonal antibodies raised against a human uterine smooth muscle extract, we have identified a novel antigen which runs as a closely spaced doublet in SDS-gels. The proteins (60/63 kDa) co-purify, are present in a 1:1 ratio as judged by Coomassie Blue staining, and are immunologically closely related, if not identical. No N-terminal sequence could be obtained from a mixture of the 60/63 kDa proteins, but the sequence of four polypeptides liberated by V8 protease or cyanogen bromide cleavage showed that the proteins are closely related to the glycolytic enzyme phosphoglucomutase type 1. Affinity-purified polyclonal antibodies and three different monoclonal antibodies to the 60/63 kDa proteins cross-reacted with rabbit skeletal muscle phosphoglucomutase type 1, whilst two additional monoclonal antibodies were specific for the 60/63 kDa proteins. Peptide maps of the 60/63 kDa proteins and phosphoglucomutase 1 are markedly different, and the purified proteins have no detectable phosphoglucomutase activity. Staining of cultured smooth muscle cells and fibroblasts with antibodies to 60/63 kDa proteins showed that the antigen is concentrated in focal contacts at the ends of actin bundles and is also associated with actin filaments. About 60% of the cellular 60/63 kDa proteins were found in the detergent-insoluble fraction, suggesting a physical association with the cytoskeleton. The highest levels of protein immunoreactivity were found in muscles. The antigen is concentrated in muscle adherens junctions, including smooth muscle dense plaques, cardiomyocyte intercalated disks, and striated muscle myotendinous junctions. Among epithelial cells, the 63 kDa isoform of the protein was found only in cultured keratinocytes where immunofluorescent staining was localized in cell-to-cell adherens junctions. Expression of the 60/63 kDa proteins in vascular smooth muscle cells is developmentally regulated and correlates with the differentiated contractile phenotype of these cells.

Abstract
Previously, we demonstrated that nondiabetic insulin-resistant monkeys had reduced covalent insulin activation of muscle glycogen synthase (GS) compared to normal monkeys and that covalent insulin activation of adipose tissue GS was absent in these monkeys. Covalent insulin activation of muscle and adipose tissue GS in monkeys with impaired glucose tolerance and noninsulin-dependent diabetes (NIDDM) was also absent. As in humans, monkeys with NIDDM have a lower urinary excretion rate of chiroinositol (CI), a component of a putative mediator of insulin action, compared to normal monkeys. To determine whether the urinary excretion rate of CI was related to insulin resistance, which develops naturally in many obese rhesus monkeys, we examined the relationships between 24-h urinary CI excretion rate and 1) whole body insulin-mediated glucose disposal rates (M) and insulin-mediated changes in 2) the skeletal muscle GS activity ratio (sm delta GSAR), 3) the skeletal muscle glycogen phosphorylase activity ratio, and 4) the adipose tissue GS activity ratio (at delta GSAR) in 27 monkeys ranging from normal (n = 12) to insulin resistant (n = 8) to overtly diabetic (n = 7). The urinary CI excretion rate was significantly correlated with M (r = 0.47; P < 0.02), sm delta GSAR (r = 0.38; P < 0.05), skeletal muscle glycogen phosphorylase activity ratio (r = -0.49; P < 0.01), and at delta GSAR (r = 0.46; P < 0.02). The urinary CI excretion rate was also correlated with glucose tolerance (r = 0.39; P < 0.05). There was a wide range of urinary CI excretion rates (0.42-5.17 mumol/day) in monkeys with normal fasting plasma glucose concentrations. However, of the 7 diabetic monkeys, 6 had a urinary CI excretion rate below 2.0 mumol/day, and in the subgroup of 16 monkeys with a urinary CI excretion rate less than 2.0 mumol/day, the associations of urinary CI with M rate (r = 0.65; P < 0.005), glucose tolerance (r = 0.63; P < 0.01), and sm delta GSAR (r = 0.73; P < 0.001) increased in strength and significance. We propose that the urinary CI excretion rate may be 1) a biochemical indicator of both in vivo and in vitro insulin resistance and 2) a noninvasive diagnostic tool with potential for the identification of those individuals at risk for NIDDM and other related diseases with insulin resistance.

Abstract
A two stage assay for detecting insulin mediator based upon its stimulation of soluble pyruvate dehydrogenase (PDH) phosphatase to activate soluble pyruvate dehydrogenase complex (PDC) has been developed. This coupled assay determines the activation of PDC by monitoring production of [14C]CO2 from [1-14C]pyruvic acid. In addition to being more sensitive than the rat liver mitoplast assay previously used, it allows for the separation and investigation of the effects of mediator on the PDH phosphatases individually. It has been previously shown that the insulin mediator stimulates the most abundant PDH phosphatase, the divalent cation dependent PDH phosphatase, by decreasing the phosphatase's metal requirement (1). A metal independent PDH phosphatase has been found in bovine heart mitochondria. This phosphatase is not immunoprecipitated by antiphosphatase 2A antibody, it is not inhibited by okadaic acid, and it is not stimulated by spermine. However, it is stimulated (more than threefold) by insulin mediator prepared from isolated rat liver membranes. It is inhibited by Mg-ATP, with half-maximal inhibition at 0.3 mM; however, this inhibition is overcome by the insulin mediator.

Abstract
We have studied the mechanism of generation of insulin mediators by using specific antibodies raised against the oligosaccharide anchor of membrane proteins. These antibodies (i) block the in vitro effects of purified insulin mediators and (ii) block the insulin-induced stimulation of pyruvate dehydrogenase in intact BC3H1 myocytes but not insulin-stimulated glucose uptake, generation of diacylglycerol, or generation of insulin mediators. When added to intact cells in the presence of insulin, these antibodies induce the accumulation of insulin mediator activity in the extracellular medium. We therefore conclude that these anti-inositolglycan antibodies block some of the effects of insulin by inhibiting the uptake of specific insulin mediators generated outside the cell.
