This paper deals with a numerical and experimental study of ultrasound induced cavitation. On the basis of a computational analysis of Gilmore’s equation for the individual bubble dynamics, a slight decrease in the pressure radiated by a single bubble immediately before reaching the transient cavitation regime is predicted. Experiments presented in this paper confirm this observation. Therefore...

Epidemiologic studies have correlated elevated plasma fibrinogen (hyperfibrinogenemia) with risk of cardiovascular disease and arterial and venous thrombosis. However, it is unknown whether hyperfibrinogenemia is merely a biomarker of the proinflammatory disease state or is a causative mechanism in the etiology. We raised plasma fibrinogen levels in mice via intravenous infusion and induced thr...

OBJECTIVE A study was established to objectively assess the effects of low-intensity electromagnetic and electric stimulation plus negative pressure on mature scars. BACKGROUND Radiofrequency plus negative pressure therapy demonstrated a favorable reorganization and regeneration of the collagen and elastic fibers and was proposed for the treatment of cellulitis and skin stretch marks. METHO...

BACKGROUND The aim of this study was to prospectively evaluate the use of elastometry in healthy volunteers and patients with acute pancreatitis using virtual touch tissue quantification (VTQ) imaging technology performed on the pancreas. MATERIAL AND METHODS We enrolled 210 healthy volunteers and 44 acute pancreatitis patients in the study between March 2012 and June 2013. Healthy subjects w...

The objective of the study is to assess the role of MMP-9, TIMP-1 & 2 as non-invasive markers of liver fibrosis in the NAFLD. The 99 patients with NAFLD and different stages of fibrosis were examined. We assessed of anthropometric indicators, biochemical analysis of blood, abdominal ultrasonic studies, the levels of MMP-9, TIMP-1 & 2. According of results of elastometry, patients were divided i...

Background: The transient tachypnea is a common respiratory problem in the neonate. One of the significant issues in pathophysiology of this disorder is the delayed reabsorption of the fluid by the neonate’s lungs and the effusion of fluid in the lungs. The purpose of this study is to evaluate the effects of restrictive fluid management in transient tachypnea of the neonate. Methods: The presen...

Aim. The purpose of our work is to find out diagnostic values serum MMP-9 and TGF-1β determination for assessing the severity liver fibrosis rate its progression in patients with chronic hepatitis C genotype 1 (CHC GT1) infection. Materials methods. 92 CHC GT1 were examined. was assessed by elastometry. calculated using T. Poynard formula. Serum levels measured ELISA method. Results. In GT1, mo...

In the conversion of fuel in the Tehran Research Reactor core from Highly- Enriched Uraniutn to Low-Enriched Uranium fuel neutronics analysis, thermal hydraulic calculations and kinetic performance of the core have to be studied. In this study, static and dynamic core performance for HEU and LEU fuels were investigated. In static conditions, two groups of neutron flux distributions in axia...

Introduction . Despite great attention to the pathogenesis of chronic viral hepatitis C (CVHC), many aspects immune response in this pathology remain unclear. Aim To study subpopulation composition blood cytotoxic T cells by flow cytometry, depending on severity clinical and morphological manifestations CVHC with genotype 1 or 3. Materials methods Clinical, laboratory examinations, determinatio...

this paper presents a method for diagnosis of eccentricity fault in a switched-reluctance motor (srm) during offline and standstill modes. in this method, the fault signature is differential induced voltage (div) achieved by injecting diagnostic pulses to the motor windings. it will be demonstrated by means of results that there is a correlation between differential induced voltage and eccentri...
