abstract   introduction: diabetes mellitus accompanies with disturbances in learning, memory, and cognitive skills in the human society and experimental animals. considering the beneficial antidiabetic potential of nigella sativum (ns ), this research study was conducted to evaluate the effect of chronic consumption of ns on learning and memory in diabetic rats using passive avoidance and y-maz...

Background and Objective: Neonatal sepsis (NS) is a major cause of mortality and morbidity in neonates. Correct and early diagnosis of NS can prevent its complications. The aim of this study was to investigate the relationship between the levels of thyroid hormones and procalcitonin (PCT) with NS. Materials and Methods: In this case control study, 40 term neonates with proven NS diagnosis and ...

We discuss geometry underlying orientifolds with non-trivial NS-NS B-flux. If D-branes wrap a torus with B-flux the rank of the gauge group is reduced due to non-commuting Wilson lines whose presence is implied by the B-flux. In the case of D-branes transverse to a torus with B-flux the rank reduction is due to a smaller number of D-branes required by tadpole cancellation conditions in the pres...

We consider non-perturbative six dimensional N = 1 space-time supersymmetric orientifolds of Type IIB on K3 with non-trivial NS-NS B-flux. All of these models are non-perturbative in both orientifold and heterotic pictures. Thus, some states in such compactifications arise in “twisted” open string sectors which lack world-sheet description in terms of D-branes. We also discuss their dual F-theo...
