Helicobacter pylori (HP) infection is one of the most frequent bacterial infections in humans. The studies performed in the last 30 years showed that this bacterium is the main cause of chronic gastritis and the main etiological agent of peptic ulcer and gastric cancer. We investigated the prevalence of HP infection in a group of 1525 patients who addressed a gastroenterology medical center bet...

BACKGROUND Ongoing Helicobacter pylori (HP) infection triggers a chronic active gastritis. Eradicating HP reduces gastric inflammation, but does not eliminate it. We sought to characterize this persistent gastritis, and demonstrate the persistence of HP-specific Th17 responses in individuals previously infected with HP but who no longer had evidence of ongoing infection. METHODOLOGY/PRINCIPAL...

The study was conducted to detect haptoglobin in seminal plasma (SP-Hp) of Awassi rams and the effect of the breeding season on its concentration, along with determining the correlation with its concentration in serum (S-Hp) and main semen variables. Pre-warmed artificial vagina was used to collect semen samples biweekly from five Awassi rams. Semen samples were evaluated for volume, concentrat...

BACKGROUND Helicobacter pylori neutrophil-activating protein (HP-NAP) is involved in H. pylori-induced gastric inflammation. Due to its immunogenic and immunomodulatory properties, HP-NAP has been used for developing vaccines against H. pylori infection and new drugs for cancer therapy. RESULTS Here, we provide a simple process for high-yield production of HP-NAP by applying one-step negative...

Honey bees use propolis to defend against invaders and disease organisms. As some colonies produce much more propolis than others, we investigated whether propolis collecting is associated with disease resistance traits, including hygienic behavior and resistance to the parasitic bee mite, Varroa destructor. The three highest (HP) and three lowest propolis-producing (LP) colonies among 36 Afric...

Background/Aims To evaluate the expression of cellular inhibitor of apoptosis protein 2 (cIAP2) during gastric carcinogenesis after Helicobacter pylori (HP) infection and after HP eradication. Methods We divided non-cancer patients into four groups according to the status of HP infection and atrophic gastritis (AG)/intestinal metaplasia (IM). We compared cIAP2 mRNA expression among these four...

background: we studied the effects of high protein (hp) and balanced diets (bds) on lipid profiles, and high‑sensitive c‑reactive protein (hs‑crp) levels in obese and overweight women. methods: in a parallel designed randomized controlled clinical trial, 60 healthy women with body mass index ≥25 kg/m2, aged 20–46 years, enrolled in an 8‑week investigation at aerobic clubs. they were categorized...

Cell suspensions of three pathogens were exposed to hydrostatic pressure (HP), bacteriocin mixture (nisin and pediocin) or a combination of HP+bacteriocins and changes in colony forming units (cfu) and cell-morphology by scanning electron microscopy (SEM) were studied. Cell viability loss, as determined from the reduction in cfu before and after a treatment, occurred in Listeria monocytogenes b...

OBJECTIVES We sought to understand the importance of oxidative stress in explaining why the haptoglobin (Hp) genotype determines myocardial infarction (MI) size in diabetes mellitus (DM). BACKGROUND Two common alleles (1 and 2) exist at the Hp locus in humans. The Hp 2 allele is associated with increased MI size in individuals with DM. In vitro, the Hp 2 protein is associated with increased g...

BACKGROUND The association of H.pylori (HP) and insulin resistance degree (IR) has not been evaluated in the diabetic patients so far. In this study, we evaluated the association between HP seropositivity and the homeostatic model assessment for insulin resistance (HOMA-IR) in diabetic patients. METHODS In this study, 211 diabetic patients admitted to the endocrinology clinic of Shahid Behesh...
