Introduction Susceptibility weighted imaging (SWI) is used routinely at clinical field strengths because of its high sensitivity to venous vasculature, blood products, and tissue iron content. This sensitivity is due to the magnetic susceptibility information in the phase images which are used to mask the magnitude images [1]. These susceptibility effects increase with the main magnetic field s...

introduction: nitric oxide (no) is a neuronal messenger molecule in the central nervous system, which is generated from l-arginine by nitric oxide synthase (nos) and involves in many important opioid-induced effects. our previous studies revealed that cuminum cyminum interestingly reduces morphine sensitization, tolerance and dependency in male mice. therefore, in the present study, the effect ...

Heat generates from power electronics must be dissipated to maintain operating temperatures within specification. Thermal management is an important design consideration in which thermal interface material (TIM) plays important role on reducing the thermal resistance between hot and cold points. AlN thin film and AlN/Al stack were used as TIM and Cu substrates was used as heat sink. The observe...

A first-principles formalism is employed to investigate the interaction of iron oxide (FeO) with a boron nitride (BN) nanotube. The stable structure of the FeO-nanotube has Fe atoms binding N atoms, with bond length of roughly ~2.1 Å, and binding between O and B atoms, with bond length of 1.55 Å. In case of small FeO concentrations, the total magnetic moment is (4 μ(Bohr)) times the number of F...

Background: Histological and histometrical effects of Fennel Essential Oil (FEO) on ovary structure were studied during postnatal development in female wistar rats. Materials and Methods: For this purpose, the female rats, after parturition divided in control, sham and experimental groups with equal number of female pups for each mother at random. Sham 1 and experimental 1 groups consisted of m...

The Yfe/Sit and Feo transport systems are important for the growth of a variety of bacteria. In Yersinia pestis, single mutations in either yfe or feo result in reduced growth under static (limited aeration), iron-chelated conditions, while a yfe feo double mutant has a more severe growth defect. These growth defects were not observed when bacteria were grown under aerobic conditions or in stra...
