background: related multidrug resistance (mdr) to efflux pumps is a significant problem in treating infections caused by pseudomonas aeruginosa (p. aeruginosa). plant compounds have been identified as pump inhibitors (epis). in the current study, the potential effect of berberine and palmatine as epis were investigated on efflux pump inhibition through focusing on different gene patterns in p. ae...

background: the pathogenesis of nontypeable haemophilus influenzae (nthi) begins with adhesion to the rhinopharyngeal mucosa. almost 38-80% of nthi clinical isolates produce proteins that belong to the high molecular weight (hmw) family of adhesins, which are believed to facilitate colonization. methods: in the present study, the prevalence of hmwa, which encodes the hmw adhesin, was determined...

BACKGROUND Direct-to-consumer genetic tests (DTC-GT) are easily purchased through the Internet, independent of a physician referral or approval for testing, allowing the retrieval of genetic information outside the clinical context. There is a broad debate about the testing validity, their impact on individuals, and what people know and perceive about them. OBJECTIVE The aim of this review wa...

PURPOSE Some studies have investigated the association of IL-2 -330T/G (rs2069762) polymorphism with cancer risk, but the previous results were conflicting and had relatively low statistical power. Thus, we performed a meta-analysis to derive a more precise estimation of the association between IL-2 -330T/G polymorphism and cancer risk. METHODS A literature search was performed systematically...

background: the presence of rennin-angiotensin components in mammalian ovaries and their involvement in ovarian physiology have been established. in the present study, effects of angiotensin ii (ang ii) on sodium-potassium adenosine triphosphatase (na+/k+/atpase) expression and development of sheep embryos was evaluated. methods: the abattoir-derived cumulus oocyte complexes (coc) were randomly...

In this research, feasibility study of integrating thermal desalination unit with Gas Turbine (GT) has been investigated using retrofit and grass root design techniques  for Lavan Island Oil Refinery which is located in Persian Gulf. According to computed parameters on developed code for the power generation unit No.1 using EES (Engineering Equation Solver) software, thermal efficiency of t...

Due to the necessity of using highly efficient power generation systems to reduce fuel consumption and air pollution, the integration of different energy systems is promising modification to achieve higher efficiency. In this paper, the integration of an Internal Reforming Solid Oxide Fuel Cell (IRSOFC)-Gas Turbine (GT)-Organic Rankine Cycle (ORC) system has been proposed. In this regard, therm...

Qatar has experienced rapid economic growth due to the discovery and production of fuel oil and natural gas (NG). The natural renewable water resources (rainfall and groundwater [GW]) are depleted; and are estimated as 71-m/per year per capita in 2005. This is far below the water poverty line of 1,000-m/yca. The GW withdrawal is excessive (compared to replenishment) and is used mainly for irrig...
