Targeting Host Sulphonyl Urea Receptor 2 Can Reduce Severity of Associated Gastritis.

Background And Aims: While most -infected individuals remain asymptomatic throughout their lifetime, in a significant proportion, the resulting severe chronic gastritis drives the development of gastric cancer. In this study, we examine a new therapeutic target, a host potassium channel regulatory subunit, SUR2 (encoded by ), with potential to protect against -associated diseases.

Methods: SUR2 gene (ABCC9) expression in human gastric biopsies was analyzed by quantitative polymerase chain reactions.

Unconventional T Cell Immunity in the Lungs of Young Children with Cystic Fibrosis.

Background: People with Cystic Fibrosis (CF) develop pulmonary inflammation, chronic infection and structural lung damage early in life, with these manifestations being prevalent among preschool children and infants. While early immune events are believed to play critical roles in shaping the progression, severity and disease burden later in life, T cells and their subsets are poorly studied in the CF lung, particularly during the formative early stages of disease.

Methods: Using flow cytometry, we analyzed Mucosal Associated Invariant T (MAIT) cells, γδ T cells, and Natural Killer T (NKT)-like cells in bronchoalveolar lavage (BAL) samples from seventeen children with CF, aged two to six years old.

Core liver homeostatic co-expression networks are preserved but respond to perturbations in an organism- and disease-specific manner.

Findings about chronic complex diseases are difficult to extrapolate from animal models to humans. We reason that organs may have core network modules that are preserved between species and are predictably altered when homeostasis is disrupted. To test this idea, we perturbed hepatic homeostasis in mice by dietary challenge and compared the liver transcriptome with that in human fatty liver disease and liver cancer.

Hepatocellular Carcinoma and Statins.

HMG-CoA reductase inhibitors (known as statins) are commonly prescribed worldwide for the management of coronary heart disease and the underlying dyslipidemia. This class of drugs has been shown to infer a significant decrease in the risk of cardiovascular morbidity and mortality. Only recently though have the beneficial effects of statins in other diseases such as non-alcoholic steatohepatitis been highlighted.

Coordinate expression loss of and in gastric cancer via impairment of a glucocorticoid-responsive enhancer.

Gastrokines (GKNs) are anti-inflammatory proteins secreted by gastric epithelial (surface mucous and pit) cells, with their aberrant loss of expression causally linked to premalignant inflammation and gastric cancer (GC). Transcriptional mechanisms accounting for GKN expression loss have not been elucidated. Using human clinical cohorts, mouse transgenics, bioinformatics, and transfection/reporter assays, we report a novel mechanism of GKN gene transcriptional regulation and its impairment in GC.

A lack of role for antibodies in regulating Helicobacter pylori colonization and associated gastritis.

Background: Helicobacter pylori occupy a unique niche, located within the mucus layer lining the stomach, and attached to the apical surface of the gastric epithelium. As such, antibodies would be expected to play a major role in regulating infection and/or pathogenesis. However, experiments using antibody-deficient mice to study gastric helicobacter infection have yielded inconsistent results, although some pointed toward antibodies increasing colonization levels and decreasing gastritis severity.

Study of the and antileishmanial activities of nimodipine in susceptible BALB/c mice.

Background & Objectives: Pentavalent antimonials are the standard treatment for cutaneous leishmaniasis (CL), however, treatment failures are frequent. Nimodipine, a calcium channel blocker is known to show promising antiprotozoal effects. Here, we investigated the antileishmanial effect of Nimodipine in both in vitro and in vivo BALB/c mice model of CL.

Efficacy of Supportive Therapy of Allergic Rhinitis by Stinging Nettle root extract: a Randomized, Double-Blind, Placebo- Controlled, Clinical Trial.

The aim of this study was to survey the exact benefit of this herb in the management of clinical and laboratory signs and symptoms of allergic rhinitis. In a randomized double blind clinical trial, 74 patients with the signs and symptoms of allergic rhinitis and a positive skin prick test were selected and randomly divided into 2 groups who were 150-mg, Urtidin F.C Tablet) or placebo for one month.

Poly (I:C)-DOTAP cationic nanoliposome containing multi-epitope HER2-derived peptide promotes vaccine-elicited anti-tumor immunity in a murine model.

In the current study we aimed at developing a vaccine delivery/adjuvant system to enhance anti-tumor immunity against the natural multi-epitope HER2/Neu-derived P5 peptide. Polyriboinosinic: polyribocytidylic acid [Poly (I:C)] is a strong immunoadjuvant able to enhance specific antitumor immunity induced by peptide-based vaccines. Nevertheless, delivering the peptide and adjuvant intracellularly into their target site remains a challenging issue.

Tramadol half life is dose dependent in overdose.

Background: Tramalol overdose is disproportionately more common in Iran. In recent years, Tramadol overdose has become one of the most common causes of poisoning admissions to emergency departments in this country. To the best of our knowledge, there is little or no information regarding the toxicokinetic properties of Tramadol such as its half life.

Immunoliposomes containing Soluble Leishmania Antigens (SLA) as a novel antigen delivery system in murine model of leishmaniasis.

Development of new generation of vaccines against leishmaniasis requires adjuvants to elicit the type and intensity of immune response needed for protection. The coupling of target-specific antibodies to the liposomal surface to create immunoliposomes has appeared as a promising way in achieving a liposome active targeting. In this study, immunoliposomes were prepared by grafting non-immune mouse IgG onto the liposomal surface.
