During a period of four years between June, IS, 1988 to June, IS, 1992 one hundred and fourteen patients with congestive heart failure (CHF) were admitted to the pediatric department of Taleghani General Hospital. During the above period, 192 patients with heart disease were hospitalized at this department and CHF was the cause of admission in 59.4% of them. Congenital heart disease (CHO) w...

Background: The alteration of Th1 and Th2 cytokine levels is the subject of controversy in pleural effusions caused by malignancy, a situation that favors a Th2 immune response. Objective: To examine the different levels of IL-4 and IL-10 (Th2 cytokines), and IL-2 and interferon-γ (IFN-γ) (Th1 cytokines) in malignant and non-malignant pleural effusions. Method: The cytokine levels in pleural fl...

An enhanced cascading failure model integrating data mining technique is proposed in this paper. In order to better simulate the process of cascading failure propagation and further analyze the relationship between failure chains, in view of a basic framework of cascading failure described in this paper, some significant improvements in emerging prevention and control measures, the subsequent f...

background: acute renal failure describes as a syndrome by rapid decline in the ability of the kidney to eliminate waste products, regulate acid–base balance, and manage water homeostasis. when this impairment is prolonged and entered chronic phase, erythropoietin secretion by this organ is decreasing and toxic metabolic accumulates and causes hematological changes include decrease of hct, mcv ...

OBJECTIVES The aim of our study was to explore evolving changes in a mitral flow velocity pattern (MFVP) and its hemodynamic and pathological correlates in hypertensive rats in an isolated diastolic heart failure model. BACKGROUND Development of left ventricular (LV) hypertrophy and concomitant diastolic dysfunction cause heart failure in hypertensive hearts even with normal systolic function...

In 3-D analyses of rock slopes there’re can be numerous sliding paths a long a coplanar nonpersistent discontinuity with a known strike. This paper describes an approach for the determination of a most probable sliding path. For this particular study, several blocks of gypsum with the dimensions of 15×15×15 cm containing coplanar non-persistent open joints were fabricated. The models have vario...

OBJECTIVE To compare the load to ultimate failure, load to a 2 mm gap, mode of failure, and gap at failure (mm) of the Teno Fix(®) (TF) to the 3-loop pulley (3LP) for repair of equine tendon lacerations. The use of 4TF devices versus 5TF devices on load to ultimate failure and load to a 2 mm gap was also compared. STUDY DESIGN Ex vivo biomechanical study; unbalanced incomplete block (horse) d...

D uring exercise testing in patients with chronic heart failure and severely depressed left ventricular function, an increased variability of gas exchange with a phenomenon of periodic breathing with an oscillatory pattern in oxygen uptake (VO2) has been recognised. 1 Previous studies were performed in adult patients with chronic heart failure related to ischaemic heart disease. The aim of the ...
