there are many evidences that human serum paraoxonase activity modifies plasma lipid profile and paraoxonase has an antiatherogenic property. non-selective beta-blockers affect plasma lipid profile too, but they have atherogenic property when patients take these drugs in long term. in this study the effect of propranolol, a non-selective beta-blocker, on paraoxonase activity was investigated. l...
background and purpose: tgf-β is a potent regulator and suppressor of the immune system and overproduction of this cytokine may contribute to immunosuppression in hiv-infected patients. increasing population of immunosuppressed patients has resulted in increasingly frequent of fungal infections, including oral candidiasis. the aim of this study was to evaluate the plasma levels of tgf-β under i...

background & objectives: pseudomonas aeruginosais one of the most important causes of nosocomial infections particularly in immunodeficient patients. several antibiotics such as betalactams, aminoglycosides and quinolones are used for the treatment of infections caused by this organism, but the prevalence of multidrug resistant strains has been reported frequently. beta lactamase production is ...
Introduction: The Alzheimer Disease (AD) is the most common form of dementia that leads to memory impairment. As the oxidative stress plays an important role in AD pathogenesis, the current study aimed at examining the protective effects of Cyperus Rotundus as an antioxidant on amyloid β (Aβ) -induced memory impairment. Methods: Twenty-eight Wistar male rats received intrahipp...
Considerable evidence suggests that mitochondrial dysfunction contributes to the toxicity of uranyl acetate (UA), a soluble salt of depleted uranium (DU). We examined the ability of the two antioxidants, beta-glucan and butylated hydroxyl toluene (BHT), to prevent UA-induced mitochondrial dysfunction using rat-isolated kidney mitochondria. Beta-glucan (150 nM) and BHT (20 nM) attenuated UA-indu...
Background: Beta thalassemia is a common health problem in Iran especially in Northern provinces. Premarital screening for thalassemia is compulsory in Iran and identification of the carriers is based on primary CBC (Cell Blood Count) and hemoglobin electrophoresis. Silent mutations on β-globin gene have borderline or normal hematological indices that cannot be detected in premarital scree...
In this paper we analyze metastability and nucleation in the context of Kawasaki dynamics for two-dimensional Ising lattice gas at very low temperature with periodic boundary conditions. Let $\beta>0$ be inverse let $\Lambda\subset\Lambda^\beta\subset\mathbb{Z}^2$ two boxes. We consider asymptotic regime corresponding to limit as $\beta\rightarrow\infty$ finite volume $\Lambda$ $\lim_{\beta\rig...

Baker (2019), Barany and Kaenmaki (2019) independently showed that there exist iterated function systems without exact overlaps are super-exponentially close cylinders at all small levels. We adapt the method of obtain further examples this type. prove for any algebraic number \(\beta\ge 2\) real numbers \(s, t\) such system \(\left \{\frac{x}{\beta}, \frac{x+1}{\beta}, \frac{x+s}{\beta}, \fr...
