Endothelial dysfunction which is manifested by the loss of nitric oxide bioavailability, is an increasingly recognized cause of cardiac syndrome X (CSX) and beta blockers are used for the treatment of this syndrome. Thus, the aim of this study was to investigate effects of metoprolol, as a beta blocker, on endothelial function in CSX patients. The study included 25 CSX patients (20 female/ 5 ma...

Let V denote a vector space over C with finite positive dimension. By a Leonard triple on V we mean an ordered triple of linear operators on V such that for each of these operators there exists a basis of V with respect to which the matrix representing that operator is diagonal and the matrices representing the other two operators are irreducible tridiagonal. Let D denote a positive integer and...

alport syndrome is a progressive hereditary nephritis leading to renal failure. nearly all of the documents declare that alport syndrome is inherited as x-linked dominant trait and reports of autosomal inheritance form is very rare. this paper presents an iranian large alport family with autosomal recessive inheritance. in our patients alport disease was confirmed with electron microscopic stud...

abstract  background: mosaic form of turner syndrome that represented by two or more  cell lines in an affected individual, often has limitation for detection with classical  cytogenetic methods. the present study was carried out to compare the efficiency of  interphase fluorescence in situ hybridisation (fish) and cytogenetic techniques in  detection of mosaic form of turner syndrome.  methods...

The quartz microbalance technique has been used to study the coverage of argon and methane films in the vicinity of the bulk triple point. In contrast to previous measurements, close to the triple point, the discontinuities in the coverage indicate first-order surface phase transitions. A thermodynamic model shows that argon forms a layered solid-liquid film in a range around the triple point, ...

We provide an elementary method to show that there exist infinitely many right-angled triangles with integral sides in which the lengths of the two non-hypotenuse sides differ by 1. The method also enables us to construct all such right-angled triangles recursively. 1. Introduction There does not exist any isoceles right-angled triangle with integral sides. Does there exist a right-angled trian...

An extended triple system with no idempotent element (ETS) is a collection of non ordered triples of type {x,y,z} or {x,x,y} chosen from a v set in such a way that each pair (whether distinct or not) is contained in exactly one triple. (For example, in the block {x,x,y}, the pair {x,y} is said to occur one tinle.) Such a design has "'v = v(v + 3) /6 blocks and a necessary and sufficient conditi...

We construct a so-called Ahmad triple in the Σ2enumeration degrees; that is, we construct three Σ2-sets A, B, and C such that A 6≤e B, B 6≤e C, ∀X (X <e A ⇒ X <e B) and ∀X (X <e B ⇒ X <e C). This constitutes a first step toward showing the ∀∃-theory of the Σ2-enumeration degrees to be decidable.

objective: fragile x syndrome is the second etiology for inherited mental retardation. it may concomitant with other psychiatric disorders. intellectual disability (id) is a state of functioning that typically begins in childhood and is characterized by limitations in intelligence and adaptive skills. we intend to introduce a male young patient with fragile x syndrome and obsessive-compulsive d...

background: cardiac syndrome x is a relatively common disorder, and still not much is known about the causative factors or its pathophysiology, which makes it difficult to cure. due to its chronic nature and debilitating symptoms, many patients have significantly reduced quality of life (qol).the purpose of this study was to assess the impact of phase iii cardiac rehabilitation (cr) and relaxat...
