Background: Study the correlation between the left ventricular end diastolic volume (LVEDV), ejection fraction (EF) and the development of arrhythmia.
Patients and methods: Two hundreds patients with documented acute coronary syndrome and myocardial infection with dysrhythmia documented by ECG and holter monitoring assessed at the cardiac department at Baghdad teaching hospital over the period Jan-Dec 2007. These dysrhythmias were corelated with left ventricular end diastolic volume and ejection fraction.
Results: The patients were divided into 4 groups according to LVEDD and EF. The 1st group, 40 patients (20%) found to have non sustained ventricular tachycardia was associated with higher LVEDD (62-72mm) and low EF (30-39%) in comparison with other groups. A 2nd group of 80 patients (40%) have occasionally ventricular ectopic, their left ventricular end diastolic dimension is (52-58 mm) and ejection fraction in higher than the 3rd group 10 patients (5%) who had atrial fibrillation were having normal left ventricular end diastolic volume but ejection fraction was 45%. A 4th group of 40 patients (20%) were having occasional atrial ectopic have both normal ejection fraction and left ventricular end diastolic volume, the remaining 30 patients (15%) from the total did not develop any arrhythmia and their left ventricular end diastolic volume and ejection fraction were normal considered an control groups.
Conclusion: It was found that the development of arrhythmia is very significantly correlated with the abnormal increased left ventricular end diastolic volume and more lowering of ejection fraction.
The influence of dye laser Rhodamine 6G (R6G) on the molecular structure of silica aerogel prepared by normal drying method is reported. The study also tests the effect of dye concentration on morphological and physical properties. Fourier Transform Infrared Spectroscopy (FTIR) was used to examine this effect, in addition to Field Emission Scanning Electron Microscopy (FESEM), contact angle, and surface area measurement. It was found from FTIR data that the dye laser stays with the inner structure of samples and, at high concentration, it gives a good influence by reducing (OH) band and increasing (CH) band, leading to changing the contact angle from (123á´¼) to (145á´¼). Whereas particle size varied from 22 n

Show MoreThe use of Near-Surface Mounted (NSM) Carbon-Fiber-Reinforced Polymer (CFRP) strips is an efficient technology for increasing flexural and shear strength or for repairing damaged Reinforced Concrete (RC) members. This strengthening method is a promising technology. However, the thin layer of concrete covering the NSM-CFRP strips is not adequate to resist heat effect when directly exposed to a fire or at a high temperature. There is clear evidence that the strength and stiffness of CFRPs severely deteriorate at high temperatures. Therefore, in terms of fire resistance, the NSM technique has a significant defect. Thus, it is very important to develop a set of efficient fire protection systems to overcome these disadvantages. This pape

The most important chemical constituents of propolis diagnosed by the Infra Red Spectroscopy, were the Flavonoids specificaly. Results showed a high antifungal activity of ethanol extract of propolis, evidently with a high concentration of extract (5) mg\ml, which completely inhibited the radial growth on both solid and liquid media (PDA &PD Broth ) of both fungi . We observed that , ethanol extract p

Objective: to compare the efficacy and safety of 1% of pimecrolimus cream versus 0.05% of clobetasol cream and 0.005% of calcipotriol cream in psoriatic patients.
Patients and methods: adults on stable plaque psoriasis were randomized to three treatment groups (pimecrolimus, clobetasol, and calcipotriol group). The criteria of inclusion involve affected BSA of ≤10%, with a local psoriasis severity index (LPSI) score of ≥5. The main assessment of clinical efficacy was the percent changes in LPSI. The quantitative determination of cytokine levels (IL -6, s IL-2R, TNF-α),
ABSTRACT:
Microencapsulation is used to modify and retard drug release as well as to overcome the unpleasant effect
(gastrointestinal disturbances) which are associated with repeated and overdose of ibuprofen per day.
So that, a newly developed method of microencapsulation was utilized (a modified organic method) through a
modification of aqueous colloidal polymer dispersion method using ethylcellulose and sodium alginate coating materials to
prepare a sustained release ibuprofen microcapsules.
The effect of core : wall ratio on the percent yield and encapsulation efficiency of prepared microcapsules was low, whereas
, the release of drug from prepared microcapsules was affected by core: wall ratio ,proportion of coa

The Y-Zeolite was synthesized by a sol-gel technique. The average size of zeolite was 92.39 nm, surface area 558 m2/g, and pore volume 0.231 cm3/g. The metals of nickel, zinc, and copper were dispersed by an impregnation method to prepare Ni/HY, Zn/HY, Cu/HY, and Ni + Zn /HY catalysts for desulfurization. The adsorptive desulfurization was carried out in a batch mode at different operating conditions such as mixing time (10,15,30,60, and 600 min) and catalyst dosage (0.2,0.4,0.6,0.8,1, and 1.2 g). The most of the sulfur compounds were removed at 10 min for all catalyst ty
