background :   imipenem-resistant gram negative bacteria, resulting from metallo-beta-lactamase (mbls)-producing strains have been reported to be among the important causes of nosocomial infections and of serious therapeutic problem worldwide. because of their broad range, potent carbapenemase activity and resistance to inhibitors, these enzymes can confer resistance to almost all beta-lactams....

hereby we report a patient with thalassemia major having extradural cord compression at t3-t9 levels due to a mass of extramedullary hematopoiesis (emh) tissue, whose treatment was successful with hypertransfusion therapy alone. the patient was a 23-year-old man who had not received regular blood transfusion since two years before admission. he suffered from paraparesis with a history of progre...

introduction: one of the most common markers in alzheimer’s disease (ad) is amyloid beta (aβ) plaques. anti-inflamm-atory agents including phagocytosis by immune cells, proteolytic enzymes and liver are known to decline the risk of aβ plaques formation. in the previous study we showed that aqueous extract of lavandula angusti-folia (lavender) improved memory deficits in alzheimeric rats. here, ...

in spite of their key role in various immunological processes occurring in the endometrium, t cells- especially + subtype- residing in this mucosal tissue, have not been extensively explored. we present here the profile of expressed genes for variable region of chain of t cell receptor (tcr) in normal endometrium as compared to peripheral blood. samples from endometrium were taken from norm...

alzheimer disease (ad) is a neurodegenerative disorder marked by cognitive and behavioral impairment. amyloid beta (aβ) peptides are involved in ad as the main component of amyloid plaques found in the brain. recent in vivo and in vitro studies have shown that there is a lot of substances that alter aβ pathogenesis of ad. aβ induces toxicity lead to increasing ros. in the other hand, 5-ht6 and ...

background pseudomonas aeruginosa is one of the most important agents causing nosocomial infections worldwide. multidrug resistance of isolated bacteria from nosocomial infections makes it difficult and sometimes impossible to treat. objectives the aim of the present study was to investigate the antibiotic resistance and association between blaimp and blavim genes with resistance to meropenem a...

background carbapenemes are a good choice for treatment of infections caused by multidrug resistant pseudomonads aeruginosa. the emergence of carbapenem resistance has become a major problem in treatment of this organism especially among immunocompromised patients including burn patients. objectives the aim of this study was to investigate carbapenem-resistance mechanisms among burn patients in...

in the past, residents of arabic island were divided into ghahtanis or hemieris in south and adnanis in north. these two were great nations that left several texts from their own language that there is no doubt about the authenticity of them. by scientific analysis of these texts, historical and literary results can be drawn. the ancient linguists believed that ghahtani's language is diffe...

Although human gamma activity (30-80 Hz) associated with visual processing is often reported, it is not clear to what extend gamma activity can be reliably detected non-invasively from frontal areas during complex cognitive tasks such as long term memory (LTM) formation. We conducted a memory experiment composed of 35 blocks each having three parts: LTM encoding, working memory (WM) maintenance...

For some $$\beta \ge 1/2$$ , a $$\varDelta _{\beta }$$ -metric graph $$G=(V,E,w)$$ is complete edge-weighted such that $$w(v,v)=0$$ $$w(u,v)=w(v,u)$$ and $$w(u,v) \le \beta \cdot (w(u,x)+w(x,v))$$ for all vertices $$u,v,x\in V$$ . A $$H=(V', E')$$ called spanning subgraph of $$G=(V, E)$$ if $$V'=V$$ $$E'\subseteq E$$ Given positive integer p, let H be G satisfying the three conditions: (i) ther...
