background: developmental dysplasia of hip (ddh) is a common childhood disorder, and ultrasonography examination is routinely used for screening purposes. in this study, we aimed to evaluate a modified combined static and dynamic   ultrasound technique for the detection of ddh and to compare with the results of static and dynamic ultrasound techniques.       methods: in this cross-sectional stu...

substitution at codon ser315 of katg gene, a reliable marker for isoniazid (inh) resistance and proliferate in spite of the loss of cell wall is called an l- form. unstable l- forms can convert to normal cells but stble l-forms can not.cell wall - deffective state may be induced spontaneously or through the action of an appropriate agent such as antibiotic interfering with the synthesis of cell...

 Abstract Background: Several studies have examined the reflex response of ankle musculature to sudden inversion in noninjured and injured subjects. To date, there have been no studies to determine the effect of versatile degrees & conditions of perturbation on the ankle musculature latency. The purpose of this study was to measure and determine whether there was a difference in ankle musculatu...

Background: Nowadays, cardiovascular diseases (CVDs) are among the most common causes of mortalities worldwide. Parathyroid hormone (PTH) has an important role in the pathogenesis of CVDs. The aim of the current study was to compare serum PTH levels between patients with acute myocardial infarction (MI), unstable angina, and normal coronary function. Methods: This descriptive and analytic stud...

In this paper we investigate the behavior of solutions, stable and unstable of the solutions a second-order rational difference equation. Also we will discuss about the behavior of solutions a the rational system, we show these solutions may be stable or unstable.  

Coronary angioplasty was performed in 53 patients in whom unstable angina had reoccurred after 48 hr and within 30 days after sustained myocardial infarction. Single-vessel disease was present in 64% of the patients and multivessel disease in 36%. The preceding myocardial infarction had been small to moderate in size in the majority of the patients. The left ventricular ejection fraction was mo...
