the growing demand for enhanced esthetic appearance has led to great developments in bleaching products. the exposure of hard tissues of the tooth to bleaching agents can affect the roughness of the enamel surface. the freshly bleached enamel surface exposed to various surface treatments such as fluoride and other remineralizing agents have been assessed in this study. the aim of this experimen...

In this study, a new sequence called the complex-type k -Pell number is defined. Also, we give properties of such as generating matrix, function, combinatorial representations, exponential representation, sums, permanental and determinantal Binet formula. Then, determine periods recurrence according to modulo id="M3"> <m...

BACKGROUND There is an increased incidence of major depressive disorder (MDD) in individuals after myocardial infarction (MI), but the pathophysiological processes mediating this association are unclear. Our previous study demonstrated an increase in pro-apoptotic pathways in the myocardium and hippocampus in MDD, which was reversed by venlafaxine. This study aimed to attempt to confirm the eff...

To provide evidence for the role of angiotensin II locally produced in the brain in the development of sympathetic hyperactivity and heart failure after myocardial infarction (MI), transgenic rats (TGR) were used, which express an antisense RNA against angiotensinogen. In TGR and control Sprague-Dawley (SD) rats, an MI was induced by acute coronary artery ligation. At 8 weeks after MI, MI sizes...

Objective:In vitro maturation is a highly effective method for achieving mature  oocytes to treat infertility based on in vitro methods (IVF-ICSI). This technique is effective for treating women who suffer from polycystic ovary syndrome (PCO) and cancer. MATERIALS AND METHODS: immature oocytes were obtained from 6-8 weeks old NMRI mice, 48 hours after intraperitoneal injection of 7.5 units of...

Background: Periodontitis is common in adults and cardiovascular diseases (CVD) are the most common cause of adult death in the world. This study aimed to investigate the relationship between CVD and periodontitis. Methods: Sixty patients with myocardial infarction (MI) as case and 63 subjects with periodontitis without MI as control were studied. Periodontitis was assessed according to Ramfjo...

Type-1 cardiorenal syndrome, characterized by acute kidney dysfunction secondary to cardiac failure and renal arteriolar vasoconstriction, is mediated by the renin-angiotensin-aldosterone axis and sympathetic nervous system activation. Previous reports indicate that angiotensin II modulates immune function and causes recruitment and activation of T-lymphocytes. The goal of this study was to eva...

PURPOSE To investigate the clinical feasibility of diffusion-weighted imaging (DWI) to detect recent myocardial infarction (MI) and to differentiate it from subacute and chronic MI, with late-gadolinium enhancement (LGE) sequence as reference. Furthermore, to measure variation of the myocardial apparent diffusion coefficient (ADC) according to the age of MI. MATERIALS AND METHODS Seventy-four...

BACKGROUND The failing myocardium is characterized by reductions of phosphocreatine (PCr) and free creatine content and by decreases of energy reserve via creatine kinase (CK), ie, CK reaction velocity (Flux(CK)). It has remained unclear whether these changes contribute directly to contractile dysfunction. In the present study, myocardial PCr stores in a heart failure model were further deplete...

A three-dimensional tissue construct was created using adipose-derived stromal vascular fraction (SVF) cells and evaluated as a microvascular protection treatment in a myocardial infarction (MI) model. This study evaluated coronary blood flow (BF) and global left ventricular function after MI with and without the SVF construct. Fischer-344 rats were separated into four groups: sham operation (s...
