Heterotopic gastric mucosa in the gallbladder is extremely unusual. In this study, we aimed to report a case of gastric heterotopia together with squamous metaplasia in the gallbladder of a 47-year-old female patient who experienced an intensive abdominal pain. He was admitted to the hospital for clinical treatment without any improvement. Ultrasonography showed a stone located in the gallbladder neck and dilatation of intrahepatic bile ducts, both hepatic ducts and common hepatic duct. Laparoscopic cholecystectomy was performed. In the microscopical examination, the epithelium of the gallbladder revealed an unspecified chronic cholecystitis. Besides, at the level of the gallbladder body, a heterotopic gastric mucosa contain chief, parietal and mucosal cells with cystic glands and squamous metaplasia was found. Actually the patient is in long-time follow-up, asymptomatic. We also review 96 other reports of HGM in the gallbladder in the international medical literature from 1934. As heterotopic tissue may promote carcinogenesis of the gallbladder, close attention should be paid to any occurrence of such lesions in this anatomical region. It appears that laparoscopic cholecystectomy may be unavoidable for patients affected by heterotopic gastric mucosa at the present time and care must be taken when a diagnosis is made based on intraoperative frozen sections. 相似文献

Annual gonad hormonal profile of wild, matured mahseer (29 males and 23 female) averaging in weight between 0.95 ± 0.26 and 1.19 ± 0.23 kg for males and females, respectively, were investigated from November 2007 to November 2008 using enzyme-linked immunosorbent assay (ELISA) technique. Blood was collected from caudal vein, monthly and plasma separation by centrifugation was done to measure reproductive hormones: 17β-estradiol (E2), testosterone (T), and 11-keto-testosterone (11KT). Gonads were sampled for histology processing to observe their maturity. Highest T level in females and males was recorded at 0.22 ± 0.016 and 0.88 ± 0.014 ng/ml, respectively. The 11KT showed several peaks and the highest value was noted at 0.7 ± 0.018 ng/ml in November 2008. The female E2 initially was at 1.48 ± 0.16 ng/ml and significantly increased (P < 0.05) to 1.53 ± 0.39 ng/ml in November 2008. Ovaries were laden with oocytes in several stages in all the samples while testes gonad showed a high level of spermatids throughout the year. Changes in plasma level of the gonadal hormones were correlated with the ovarian and testes maturities. In conclusion, the study suggests that mahseer can be categorized as asynchronized and multiple spawner. The information gathered is important for appropriate breeding and conservation programs of the Malaysian mahseer. 相似文献

The molecular basis of coronary artery disease (CAD) has been widely studied in the western world but there is no published work on the Malaysian population. This study looked at the global gene expression profiling of the peripheral blood of patients with CAD from the 3 main ethnic groups in Malaysia. Male subjects selected were based on angiographically confirmed CAD (≥50% stenosis) and normal control subjects (0% stenosis) with age range of 55.6±5.3 and 51.0±5.5years, respectively. The global gene expression of 12 angiographically documented CAD patients and 11 matched control subjects were performed. The combined group samples identified 6 up regulated differential expression (DE) genes (GHRL, LTA, CBS, HP, ITGA2B, and OLR1) and 12 down regulated DE genes (IL18R1, ITGA2B, IL18RAP, HP, OLR1, SOD2 ITGB3, IL1B, MMP9, PLA2G7, UTS2, and CBS) to be involved in CAD at the fold change of 1.3 with fault discovery rate (FDR) of 1%. Three genes, MMP9, IL1B, and SOD2 were down regulated in all the 3 ethnic groups making them potential biomarker candidates for CAD across all three ethnicities. Further verification in a cohort study is needed. 相似文献

Purpose of Review
The purpose of this review is to highlight recent hardware and software advances in coronary computed tomography angiography (CTA) that make it a potentially viable alternative to invasive coronary angiography for surveillance of cardiac allograft vasculopathy (CAV) in heart transplant recipients.Recent Findings
Dual-source CT, multisegment reconstruction, and intracycle motion correction algorithms are all technologies applied during or after image acquisition that can improve image quality and diagnostic accuracy in patients with elevated heart rates, such as heart transplant recipients. CT fractional flow reserve may also add value in this clinical scenario.Summary
Coronary CTA now has equivalent diagnostic accuracy, offers more nuanced anatomic information, is inherently safer, and could be less costly than invasive coronary angiography. For these reasons, coronary CTA may now be a viable alternative to ICA for CAV surveillance in heart transplant recipients.37.

Despite major insecticide-based vector control programs, dengue continues to be a major threat to public health in urban areas. The reasons for this failure include the emergence of insecticide resistance and the narrowing of the spectrum of efficient products. Cigarette butts (CBs), the most commonly discarded piece of waste, also represent a major health hazard to human and animal life. CBs are impregnated with thousands of chemical compounds, many of which are highly toxic and none of which has history of resistance in mosquitoes. This study was performed to examine whether exposure to CB alters various biological parameters of parents and their progeny. We examined whether the mosquito changes its ovipositional behaviors, egg hatching, reproductive capacity, longevity and fecundity in response to CB exposure at three different concentrations. Females tended to prefer microcosms containing CBs for egg deposition than those with water only. There were equivalent rates of eclosion success among larvae from eggs that matured in CB and water environments. We also observed decreased life span among adults that survived CB exposure. Extracts of CB waste have detrimental effects on the fecundity and longevity of its offspring, while being attractive to its gravid females. These results altogether indicate that CB waste indirectly affect key adult life traits of Aedes aegypti and could conceivably be developed as a novel dengue vector control strategy, referring to previously documented direct toxicity on the larval stage. But this will require further research on CB waste effects on non-target organisms including humans. 相似文献

Objective : We compared use of intravenous (IV) normal saline (NS) to sodium bicarbonate (NaHCO3) with or without oral N‐acetylcysteine (NAC) for prevention of contrast‐induced acute kidney injury (CI‐AKI). Background : CI‐AKI is associated with significant adverse clinical events. Use of NAC has produced variable results. Recently, intravenous hydration with NaHCO3 for CI‐AKI prophylaxis has been adopted as standard treatment for patients with stable chronic renal disease undergoing catheterization procedures. Methods : We prospectively enrolled 320 patients with baseline renal insufficiency scheduled to undergo catheterization. Patients were randomly assigned to receive either IV NS ± NAC (n = 161) or IV dextrose 5% in water containing 154 mEq/l of NaHCO3 ± NAC (n = 159). IV NS was administered at 1 ml/kg body weight for 12 hr preprocedure and 12 more hr postprocedure. IV NaHCO3 was administered at 3 ml/kg body weight for 1 hr preprocedure followed by 1 ml/kg body weight postprocedure. A 1,200 mg oral dose of NAC was given 2–12 hr preprocedure and 6–12 hr postprocedure in 50% of patients in each study arm. CI‐AKI was defined as an increase of >0.5 mg/dl or >25% above baseline creatinine. Results : Overall incidence of CI‐AKI was 10.3%. There was no significant difference in incidence among the two groups (NS ± NAC 11.8% vs. NaHCO3 ± NAC 8.8%, p = ns). Incidence of CI‐AKI increased with increasing age (p = 0.001), contrast agent use >3 ml/kg body weight (p = 0.038) and diuretic use (p = 0.005). Conclusion : Incidence of CI‐AKI was no different in the NaHCO3 group compared to NS group, and NAC did not reduce CI‐AKI in the two study arms. © 2011 Wiley Periodicals, Inc. 相似文献

This paper investigated the effects of Pr6O11 and Co3O4 on the electrical properties of ZnO-BaTiO3 varistor ceramics. The Pr6O11 doping has a notable influence on the characteristics of the nonlinear coefficient, varistor voltage, and leakage current where the values varied from 2.29 to 2.69, 12.36 to 68.36 V/mm and 599.33 to 548.16 µA/cm2, respectively. The nonlinear varistor coefficient of 5.50 to 7.15 and the varistor voltage of 7.38 to 8.10 V/mm was also influenced by the use of Co3O4 as a dopant. When the amount of Co3O4 was above 0.5 wt.%, the leakage current increased from 202.41 to 302.71 μA/cm2. The varistor ceramics with 1.5 wt.% Pr6O11 shows good nonlinear electrical performance at higher breakdown voltage and reduced the leakage current of the ceramic materials. Besides, the varistor sample that was doped with 0.5 wt.% Co3O4 was able to enhance the nonlinear electrical properties at low breakdown voltage with a smaller value of leakage current. 相似文献
