Abstract Background Abdominal pain of uncertain aetiology (non-specific abdominal pain; NSAP) is the commonest reason for emergency surgical admission. The aim this study was to examine role early laparoscopy in management NSAP. Methods Some 120 patients, admitted between November 1995 and October 1998 with acute aetiology, were randomized into two groups: group 1 had during first 18 h admission 2 close observation, conventional investigation intervention if signs peritonism developed....

Methylation of CpG islands (CGIs) in the promoter regions tumour suppressor genes is common colorectal cancer and occurs also an age-dependent manner morphologically normal mucosa. In this study, we quantified level methylation six associated with Wnt signalling pathway (adenomatous polyposis coli, DKK1, WIF1, SFRP1, SFRP2 SFRP5) together long-interspersed nuclear element-1 as a surrogate for global methylation. DNA was analysed 260 individual crypts obtained from eight female patients no...

This qualitative study examined the medication-taking behaviors and attitudes of participants determined to be 100% adherers antiretroviral therapy from a NIH-funded testing 12-week telephone adherence intervention. Using open-ended questions, interviewers collected data on sample 13 informants, whose medication randomly selected was 100%, based 30-day collection using electronic event monitoring (EEM). The analysis revealed 'successful management' as core category or main theme. achieved...

Bulk acoustic wave (BAW) filters operating at center frequency of 3.7GHz, comprising BAW resonators utilizing single crystal aluminum nitride (AlN) piezoelectric films epitaxially grown on silicon carbide (SiC) substrates, are reported. Metal-organic chemical vapor deposition (MOCVD) growth was used to obtain AlN 150-mm diameter c-plane semi-insulating SiC substrates with (0004) X-ray diffraction (XRD) rocking curve full-width half-maximum (FWHM) 0.025°.

BackgroundLaparoscopic cholecystectomy (LC) can be technically challenging in the obese. The primary aim of trial was to establish whether following a Very Low Calorie Diet (VLCD) for two weeks pre-operatively reduces operation time. Secondary outcomes included perceived operative difficulty and length hospital stay.MethodsA single-blinded, randomized controlled consecutive patients with symptomatic gallstones BMI >30 kg/m2 46 were VLCD or normal diet prior LC.

The role of ischaemia in the pathogenesis acute pancreatitis is unknown. Some experimental studies have shown that has little effect on pancreas, while others found an association with pancreatic injury. Ischaemia-reperfusion damage been well documented other sites such as intestine, cardiac muscle, and skeletal muscle. However, injury usually seen only after complete ischaemia, which uncommon clinically. Experimental chronic characterized by low blood flow, interstitial pH, impaired tissue...

Over a 14-year period 34 patients were referred for surgical treatment of insulinoma. The diagnosis was confirmed by demonstrating hypoglycaemia with inappropriate hyperinsulinaemia during prolonged fasting. Selective visceral angiography localized 30 solitary benign insulinomas and two carcinomas. In islet cell hyperplasia, demonstrated single lesion only. Ultrasonography had sensitivity 15 per cent computed tomography 24 in the localization tumours. All but one treated operation. Eighteen...

High-fat diet (HFD) induced obesity and concomitant development of insulin resistance (IR) type 2 diabetes mellitus have been linked to mitochondrial dysfunction. However, it is not clear whether dysfunction a direct effect HFD, or if function reduced with increased HFD duration. We hypothesized that the oxidative lipid metabolism functions in skeletal muscle mitochondria for mice are similar, elevated, relative standard (SD) mice; thereby, IR neither cause nor consequence applied chemical...
