Background: The normal decline in systolic blood pressure during recovery phase of treadmill exercise dose not occur in most patients with coronary artery disease, in others recovery values systolic blood pressure may even exceed the peak exercise value. Objectives: Treadmill exercise test parameters indicating the presence and extent of coronary artery disease have traditionally included such as exercise duration, blood pressure and ST-segment response to exercise. The three –minute systolic blood pressure ratio is another important indicator of presence and significance of coronary artery disease is useful and obtainable measure that can be applied in all patients who are undergoing stress testing for evaluation of suspected ischemic heart disease and this increase the sensitivity of exercise test . Type of the study: A prospective study. Methods: Between April 2011 and April 2012 ,all patients underwent treadmill exercise test , echocardiography coronary angiography in Ibn Ab-bitar Hospital Cardiac Surgery. Clinical and procedural data for patients undergoing treadmill and coronary angiography were prospectively collected and entered into database specially designed for the present study.To calculate mean systolic blood pressure ratio for each , Measurement of blood pressure in the 3rd minute of recovery time and divided by peak systolic blood pressure during exercise test ,after excluding patients . Coronary angiography was done for all patients who under went treadmill exercise test and multiple views were taken accordingly to clarify the lesion and critical lesion defined as >50% stenosis in LMS and >70% stenosis in LAD,LCX and RCA. Results: We studied 100 patients In the period from April 2011 to April 2012, 78(78%) male and 22 (22%) a female with a mean age 55.49±7.60 who undergone treadmill exercise testing and coronary angiography to assess the chest pain, 32 patient had normal blood pressure 68 had hypertension and 24 patients had normal coronary angiography and 76 patients had abnormal coronary angiography. SBP/3 minute recovery blood pressure ratio was significantly higher in patient with coronary artery disease than patient without coronary artery disease (mean ±SD O.92±0.09 VS 0.81 SBP/3 minute recovery blood pressure ratio was significantly related with the severity of coronary artery disease its higher in three vessels than one vessel disease 0.95±0.10 vs0. 91 ±0.01 p-value 0.0001. Conclusions: post exercise blood pressure response in patients with coronary artery diseaseis higher than patients with normal coronary artery .post exercise blood pressure is related to the severity of coronary artery disease

This research deals with the subject of the provisions of the autistic in criminal penalties, one of the important issues, especially after the spread in abundance in our contemporary society, as the patient is characterized by autism in most of spaces of isolation and depression and aggressive behavior, and in some cases try autistic to commit suicide as a result of going through the psychological pressure , was this research to clarify what follows autistic criminal penalties as a result of the capital crime of self or without them, and the stat
... Show MoreThe gamma camera, along with SPECT and PET scanners, is one of the main imaging technologies in nuclear medicine. A collimator is typically constructed from tungsten to provide high absorption of gamma photon energies. It has a hole or holes for imaging. Gamma rays from a radioactive source within the body are emitted in all directions, while the photons required constructing an image travel through the hole. A scintillator is the most common material used to convert the high energy of gamma radiation into a lowenergy optical photon. These detectors are one of the primary secrets to radio-diagnosis in nuclear medicine. The photomultiplier tube (PMT) is a versatile device with extraordinarily highly sensitivity and response. A typical photom

Show MoreVarious Hall Effects have been successfully observed in samples of n-type indium antimonide with values for conductivity, energy gap, Hall mobility and Hall coefficient all agreeing with theory. A particular interest in developing a method for obtaining accurate values of carrier concentrations in semiconductor samples has been fulfilled with an experimental result of (1.6×1016 cm-3 ±10.7%) giving a percentage difference of (6.7%) to a quoted value of (1.5×1016cm-3) at (77K) using an (80mW C.W. CO2) laser beam at (10.6μm) to illuminate a similar sample of n-type indium antimonide, an "Optical" Hall effect has been observed. Although some doubt has been raised as to the validity of effect i.e. "thermal" rather than "Optical", values o

Inclusive education has experienced a number of positive educational trends and developments in many different countries, typically by recognising that all students, including those who have special educational needs (SEN), have a right to education. Inclusion of children with SEN in mainstream schools, alongside their peers, has become a major concern for interested educators, professionals and parents in many countries around the world. The reasons for this trend are due to a number of factors such as the increasing attention to the role of education in achieving social justice for pupils with SEN; the right of individuals with SEN to be educated along with their typically developing peers in mainstr

The method is based on the formation of the Schiff’s base between the primary amino group present in thiamine hydrochloride and aldehyde group present in the vanillin reagent to produce a yellow colored complex having maximum absorption at 390 nm. Beer’s law has obeaid over the concentration range of 2-28µg/mL, with molar absorptivity of 0.96x104L/mol.cm. The average recovery which is a measure of accuracy is 100±1.3% and the relative standard deviation (RSD) is less than1.5 .The present method is considered to be
