1. The heterogeneic distribution of Helicobacter pylori cag pathogenicity island reflects different pathologies in multiracial Malaysian population
ABSTRACT Background: Helicobacter pylori harbouring cag-pathogenicity island (cagPAI) which encodes type IV secretion system (T4SS) and cagA virulence gene are involved in inflammation of the gastric mucosa. We examined all the 27 cagPAI genes in 88 H. pylori isolates from patients of different ethnicities and examined the association of the intactness of c

2. EVALUATION OF PSORIASIS TREATMENT WITH ESOMEPRAZOLE - A PILOT STUDY
RESUMO CONTEXTO: A psoríase é uma doença inflamatória da pele que afeta 1%-3% das populações caucasianas e pode ser persistente, desfigurante e estigmatizante. Inibidores da bomba de prótons (IBP) são potentes bloqueadores da secreção de ácido no estômago. Eles são considerados como os agentes de escolha para o tratamento de doenças ácido-p�

3. Antidiarrheal effect of extract from the bark of Combretum leprosum in mice
Abstract This study investigated the effects of the ethanolic extract from the bark of Combretum leprosum (ECL) on intestinal transit and castor-oil induced diarrhea in mice. The oral administration of ECL (750 and 1000 mg/kg) slowed intestinal transit (ID50 of 455 mg/kg). The ECL (250-1000 mg/kg) reduced castor-oil induced diarrhea, in a time- and dose-depe

4. Decreased mRNA Expression of Cystathionine Gamma lyase and H2S Concentration in Gastric Mucosal Tissue in Diabetic Rats
ABSTRACT Background and aim: It is well established that the rate of gastric lesions increases in diabetic rats. Recently, the protective effect of hydrogen sulfide (H2S) in gastric mucosa has been proven. This study aimed to determine the release of H2S and mRNA expression of cystathionine gamma lyase (CSE) in gastric mucosa in alloxan-diabetic rats in resp

5. Hypoglycemia caused by co-secretion of insulin from lung tumor and cardia cancer: first case report
ABSTRACT CONTEXT: Non-islet-cell-tumor-induced hypoglycemia (NICTH) is caused on rare occasions by secretion of insulin from tumor cells that are reported to have a single tissue origin. CASE REPORT: A 67-year-old male patient had cardia adenocarcinoma and concomitant lung adenocarcinoma with extensive metastases and repeated episodes of intractable hypo

6. Helicobacter pylori with East Asian-type cagPAI genes is more virulent than strains with Western-type in some cagPAI genes
Abstract The severity of Helicobacter pylori-related disease is correlated with the presence and integrity of a cag pathogenicity island (cagPAI). cagPAI genotype may have a modifying effect on the pathogenic potential of the infecting strain. After analyzing the sequences of cagPAI genes, some strains with the East Asian-type cagPAI genes were selected for

7. Role of microRNAs in the treatment of type 2 diabetes mellitus with Roux-en-Y gastric bypass
The aim of this study was to investigate the effect of Roux-en-Y gastric bypass (RYGB) on the peripheral blood microRNAs (miRNAs) of patients with type 2 diabetes mellitus (T2DM). miRNAs are small 20- to 22-nucleotide (nt) noncoding RNAs. They constitute a novel class of gene regulators that negatively regulate gene expression at the post-transcriptional lev

8. Copaifera langsdorffii: evaluation of potential gastroprotective of extract and isolated compounds obtained from leaves
AbstractGastric ulcer is a prevalent gastrointestinal disease, and the drugs currently used in the treatment produce several adverse effects. In this context, the search for new therapeutic antiulcer agents is essential, and medicinal plants have great potential. Here, we investigated the gastroprotective properties of Copaifera langsdorffii Desf., Fabaceae,

9. Safflower oil: an integrated assessment of phytochemistry, antiulcerogenic activity, and rodent and environmental toxicity
Gastric ulcers are a significant medical problem and the development of complications lead to significant mortality rates worldwide. In Brazil, Carthamus tinctorius L., Asteraceae, seeds essential oil, the safflower oil, is currently used as a thermogenic compound and as treatment for problems related to the cardiovascular system. In this study, by Raman spe

10. Water-induced modulation of Helicobacter pylori virulence properties
While the influence of water in Helicobacter pylori culturability and membrane integrity has been extensively studied, there are little data concerning the effect of this environment on virulence properties. Therefore, we studied the culturability of water-exposed H. pylori and determined whether there was any relation with the bacterium’s ability to adher

11. Stress-related hormone norepinephrine induces interleukin-6 expression in GES-1 cells
In the current literature, there is evidence that psychological factors can affect the incidence and progression of some cancers. Interleukin 6 (IL-6) is known to be elevated in individuals experiencing chronic stress and is also involved in oncogenesis and cancer progression. However, the precise mechanism of IL-6 induction by the stress-related hormone nor

12. Gastroprotective effect of leaf extracts of Basella alba var. alba against experimental gastric ulcers in rats
The aqueous and ethanol extracts of the leaves of Basella alba L. var. alba Wight, Basellaceae, were investigated for antiulcer activity on rats employing the pylorus ligation and ethanol induced ulcer models. The various gastric secretion parameters such as total acidity, free acidity, gastric acid volume, pH and histopathological parameters such as ulcer i
