Background: Dobutamine stress echocardiography (DSE) is a well established non invasive test for the diagnosis and risk stratification of patients with coronary artery disease. Aim of the study was to conduct a pilot study in order to establish the basis for the future routine practice of DSE in our center (Ibn Al- Bitar Hospital for Cardiac Surgery).
Patients and Methods: Fifty consecutive patients who were referred from the outpatient of our center, from August 2007 to July 2008, were included. The age range was 39 – 70 years with an average of 57.18 years. Fifty-eight percent were males. Patients were enrolled in the study in accordance with the American Heart Association/ American College of Cardiology guidelines, including mainly those who are unable to exercise due to an orthopedic problem (26%) or limited functional capacity (30%). Some Patients with resting electrocardiographic changes (20%) and non diagnostic exercise test (14%) were also included as well as five patients (10%) for the assessment of myocardial viability. The baseline echocardiogram was normal in 44 % of cases. Others had resting wall motion abnormalities due to previous myocardial infarction (50%) or left bundle branch block (6%). Dobutamine was given by a syringe or an infusion pump at incremental doses (every three minutes) of 5,10,20,30, and finally 40 μg/kg/min. Atropine was needed at peak test in 36% of cases to increase the proportion of patients who reach the target heart rate.
Results: The test was positive in 5 patients (10%); negative in 34(68%), non diagnostic in 2(4%), aborted due to intolerable symptoms in 3(6%) and stopped due to arrhythmias in 3(6%) patients. Side effects included chest tightness and irritability in 40%, headache in 12%, nausea and vomiting in 10%, and postural hypotension in 4%. Infrequent ventricular/atrial ectopics occurred in 13%, supraventricular tachycardia in one patient, and complex multiple ventricular ectopics in 3 patients; no incidence of sustained ventricular tachycardia or ventricular fibrillation occurred. There was no incidence of myocardial infarction or death.
Conclusions: DSE is a safe and practical test provided it is used according to the recommendedprotocols. A special unit for DSE in our centre is recommended.
The tentative list of the biodiversity (plants and vertebrates) of Bahr Al-Najaf depression is found to comprise 104 vertebrate species including 2 fishes, 14 reptiles, 73 resident and migratory birds and 15 mammals. The flora consists of 31 species, mainly of plants well adapted to desert conditions that dominate the area, besides few examples of water plants. The salinity was found, through chemical analysis of the lake water, to be of high value which reduces the diversity of aquatic animal and plant diversity.
Objective : Sciatic nerve block (popliteal approach) and femoral N block is a new technique other than general anesthesia in below knee surgery because it provides adequate muscle relaxation, with good intraoperative and post-operative analgesia. Nefopam is non opioid, non-respiratory depressant and non-sedative was mixed with local anesthetics drug to study the effects. This study was done to compare the onset and duration of sensory and onset time and duration of action of motor block following administration of either bupivacaine alone with administration of bupivacaine and Nefopam in patients undergoing below knee lower limb surgeries under ultrasound guided regional anesthesia.
Methods: 100 patients with American society of anest
Developing a new adaptive satellite images classification technique, based on a new way of merging between regression line of best fit and new empirical conditions methods. They are supervised methods to recognize different land cover types on Al habbinya region. These methods should be stand on physical ground that represents the reflection of land surface features. The first method has separated the arid lands and plants. Empirical thresholds of different TM combination bands; TM3, TM4, and TM5 were studied in the second method, to detect and separate water regions (shallow, bottomless, and very bottomless). The Optimum Index Factor (OIF) is computed for these combination bands, which realized

Creatine kinase in serum is affected by thyroid hormones. This study was undertaken to investigate the relationship between malondialdehyde as a general lipid peroxidation marker and CK activity in patients with primary hypothyroidism and Hoffman's syndrome which indicatees hypothyroidism with undetectable FT3 and FT4 in serum with elevated values of TSH.
The study revealed that MDA is within the normal range, while CK activities in sera of Hoffman's syndrome were increas

This study was conducted to assess the effectiveness of PRF as a graft material and membrane in dehiscence and fenestration defects. Materials and Methods: This prospective clinical study included patients who received dental implants that demonstrated peri-implant defects which were augmented using Leukocyte- PRF (L-PRF) or Advanced-PRF (A-PRF). Twenty four weeks postoperatively the defect resolution and the density of regenerated bone were assessed by CBCT and re-entry surgery. The assessment also included measurement of primary and secondary implant stability

In this paper, a theoretical study to the effect of journal misalignment on the static characteristics of oil filled porous journal bearing when lubricated with couple stress fluid has been carried out.
The analytical model used through this work is for a bearing with isotropic permeability. Considering isotropic permeability the Reynolds' equation for the oil film is modified to include a so – called filter term and the effect of fluid coupled stress. The pressure equation for the porous medium is obtained from Darcy's law and continuity equation. The equation which was used to evaluate the oil film thickness was modified to include the effect of possible misalignment in longitudinal and transverse directions. The governing eq
