the effect of three levels (0, 28.65, 57.31mg /200mg substrate) of golpar (heracleum persicum: hp) on in vitro rumen ecosystem and on methane production was assessed. gas production (gp) was recorded from 1 to 54h past of incubation. the parameters studied were in vitro gas production (ivgp), methane production, ammonia-n concentration (nh3-n), in vitro organic matter degradability (ivomde), pa...

autoimmune thyroid diseases (atd) are multifactorial conditions that result from genetic predisposition in combination with environmental risk factors. helicobacter pylori infection as an environmental risk factor has been proposed to imitate the antigenic components of the thyroid cell membrane and may play a leading role in the onset of the autoimmune diseases, such as hashimoto thyroiditis. ...

background: association between helicobacter pylori (hp) infection and migraine and the effect of hp eradication on relief of migraine headache have been studied but the results are controversial. objectives: to evaluate the effect of hp eradication in treatment of patients affected by migraine. materials and methods: eighty consecutive hp infected patients affected by migraine without aura wer...

Seasonal hibernation in mammals is under a unique adaptation system that protects organisms from various harmful events, such as lowering of body temperature (Tb), during hibernation. However, the precise factors controlling hibernation remain unknown. We have previously demonstrated a decrease in hibernation-specific protein (HP) complex in the blood of chipmunks during hibernation. Here, HP i...

background: the main purpose of the current study was to determine the effect of treating helicobacter pylori (hp) infection on seizure frequency in patients with refractory epilepsy. methods: a small sample of adult patients above 18 years of age with a diagnosis of refractory epilepsy was studied at the outpatient epilepsy clinic at shiraz university of medical sciences, from january 2009 thr...

several studies have assessed association between helicobacter pylori infection and thrombotic ischemic stroke. this study was designed to investigate the association between this organism and ischemic strokes. antibody against h. pylori (hp igg) was measured in 81 patients with stroke and 43 subjects without stroke. hp igg titer more than 20u/ml was defined as positive. 67.4% of control subjec...

abstract background and objective: helicobacterpylori(hp) is the most common bacterial infection in the world and it may be associated with chronic gastritis, pepticulcer disease, and gastricadenocarcinoma. the aim of this study was to determine the prevalence of hp in student of golestan university of medical sciences (goums). material and methods: this cross-sectional study was conducted on s...

A certain squarefree monomial ideal HP arising from a finite partially ordered set P will be studied from viewpoints of both commutative algbera and combinatorics. First, it is proved that the defining ideal of the Rees algebra of HP possesses a quadratic Gröbner basis. Thus in particular all powers of HP have linear resolutions. Second, the minimal free graded resolution of HP will be construc...

Helicobacter pylori (Hp) is the main cause of gastritis, peptic ulcer disease and gastric cancer. There are still unanswered questions related to the interaction between Hp and man, like what determines the susceptibility for the initial infection and the mechanisms for the carcinogenic effect. The initial infection seems to require a temporal gastric hypoacidity. For Hp to survive in the gastr...
