objective: : polycystic ovary syndrome (pcos) is one of the most common hormonal disorders that can lead to irregular menstrual cycles and hyperandrogenism. reduced levels of progesterone and increased estrogen in these women can perpetually stimulate the endometrial tissue of the uterus. in this study, the effect of pcos induction was studied using estradiol valerate. materials and methods: ad...

place is a part of geographical space and a base for establishment of social relations. each place is unique according to its specific properties, functions and history. meanwhile, some places find symbol identity due to their especial historical events and properties and this identity would be maintained in the minds and moved to the other generations. for example azadi tower in tehran and sav...

We investigate experimentally the effects of externally applied strain on injection 180$^\circ$ domain walls (DW) from a nucleation pad into magnetic nanowires, as typically used for DW-based sensors. In our study strain, generated by substrate bending, induces in material uniaxial anisotropy due to magnetoelastic coupling. To compare effects, $Co_{40}Fe_{40}B_{20}$, $Ni$ and $Ni_{82}Fe_{18}$ s...

BACKGROUND MRI of specific components in atherosclerotic plaque may provide information on plaque stability and its potential to rupture. We evaluated gadofluorine in atherosclerotic rabbits using a new MR sequence that allows plaque detection within 1 hour after injection and assessed enhancement in lipid-rich and non-lipid-rich plaques. METHODS AND RESULTS Twelve rabbits with aortic plaque ...

background the caudal approach to the epidural space has been used for decades to treat low back pain caused by lumbosacral root compression. the use of fluoroscopy during epidural steroid injection is the preferred method for placing the needle more accurately in the sacral hiatus, but it carries the risk of radiation hazard. objectives the aim of the study was to assess the anatomical structu...

UNLABELLED Macrophages play a key role in atherosclerotic plaque rupture. The iodine-based contrast agent N1177 accumulates in macrophages, allowing for their detection with CT. In this study, we tested whether the intensity of enhancement detected with CT in the aortic wall of rabbits injected with N1177 correlated with inflammatory activity evaluated with (18)F-FDG PET/CT and macrophage densi...

To study what determines the arthritogenicity of bacterial cell walls, cell wall-induced arthritis in the rat was applied, using four strains of Lactobacillus. Three of the strains used proved to induce chronic arthritis in the rat; all were Lactobacillus casei. The cell wall of Lactobacillus fermentum did not induce chronic arthritis. All arthritogenic bacterial cell walls had the same peptido...

the aim of this experiment was to study the effect of in ovoinjection of royal jelly (rj) on growth performance and immune response in broiler chickens challenged with newcastle disease virus. a total of 200 hatching eggs were divided into four groups of 50 eggs each one using a completely randomized design. the eggs were injected with sterilized sodium bicarbonate buffer (ph=10.4) or rj (88%) ...
