Mansoor Ahmad,Farah-Saeed,Mehjabeen,Noor Jahan
International Research Journal of Pharmacy , 2013, DOI: 10.7897/2230-8407.04326
Abstract: Thuja occidentalis (family: Cupressaceae) has been used as antiseptic, expectorant, diuretic and in the treatment of cancer and removal of kidney stones in different systems of medicine. The present studies were carried out on T. occidentalis leaves extract to evaluate the hematological and biochemical effects on rabbits. The animals were divided in to control (A and B) and treated (C and D) male and female groups (n=5). There was a slight decrease in Hemoglobin, Red blood cell count and Hematocrit/Packed cell volume values, while a significant increase in platelet count was observed in male and female treated groups. However, slight increase in total leukocyte count value in male treated group and decrease count with female treated group was also observed. Urea, Creatine phospho kinase, Creatine phospho kinase iso-enzyme, Direct Bilirubin, Gamma-glutamyl transpeptidase, Cholesterol and Albumin/Globulin ratio values were elevated in male treated group. While Phosphorus, Uric acid, Lactate dehydrogenase, Serum glutamic oxaloacetic transaminase, serum glutamic-pyruvic transaminase, Alkaline Phosphatase, Cholesterol, Triglycerides, High density lipoprotein, Low density lipoprotein, Very-low-density lipoprotein, Globulin and Blood Glucose values were found low. In female treated group almost same results were observed like male treated group except that hypoglycemic effect was more pronounced in female treated group. These findings suggested that when results of hematological and biochemical parameters of test groups (C & D) were compared with their respective controls (A & B), significant changes were observed which contributes towards the diversified therapeutic effect of T. occidentalis.

Journal of Tehran University Heart Center , 2006,
Abstract: Background: To evaluate the frequency, clinical presentation and cardiac involvement of children with RF in the North-East of Iran. Methods: A case series analysis was conducted on 80 patients with acute rheumatic fever (ARF), who were hospitalized at Ghaem hospital in Mashad between 1994 and 2000, were studied. Laboratory tests and results from echocardiographic examinations, and clinical findings were analyzed. All patients received standard care for children with ARF. The X2 test was used for comparison of binary data. Results: When compared to similar studies from developed countries, our study demonstrates a decreased frequency of RF in North-East Iran over the past few years. However, it is still a major health problem and the most common cause of acquired heart disease in childhood. The distribution of the major modified Jones criteria in our study is slightly different from that described in the literature, with a higher incidence of carditis. Conclusion: It appears that carditis is endemic in this region. Considering the high morbidity and complications involved in this disease, there is an immediate need for effective preventive programs for the initiating cause streptococcal infections, especially since it is treatable.
A Model for FeSiMg Alloy Production by Reduction Technique  [PDF]

Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2011, DOI: 10.4236/jmmce.2011.109067
Abstract: Ferrosilicon magnesium is basic foundry alloys used for the production of ductile cast iron. Magnesium content plays an important role in the produced alloy grades from dolomite ore. The focus of the present work is to simulate mathematical model to predict magnesium content in the ferrosilicon magnesium, which produced by silicothermic reduction of calcined dolomite. The basic assumptions of this model are: constant low viscosity of molten charge, the reaction is irreversible of second order and the reaction is isothermal. The reaction is based on the following equation: 2MgO+2Si →Mg2Si+SiO2 The results of previous work was found to be in a good coincidence with the predicted values by the model [Mg]=(MgO0)[Si0][eKt[(MgO0)-[Si0]]-1]/ (MgO0)[eKt[(MgO0)-[Si0]]-[Si0]] where [Mg] is the concentration of magnesium metal in ferrosilicon magnesium alloy in mol/L. [Si0] and (MgO0) are the initial concentration of silicon and magnesium oxide in charge in mol/L, while t is time in second, K is the reaction rate constant ( 3.26588x10-7 L Sec-1 mol-1). The predicted values are greater than the experimental values; this may be attributed to the use of concentration instead of the activity. The predicted values of magnesium content in ferrosilicon magnesium alloy are in a good agreement with the experimental results obtained in previous work at low viscosity.

International Journal of Clinical Medicine (IJCM) , 2011, DOI: 10.4236/ijcm.2011.21009
Abstract: Annually, an estimated 1,285,000 in-patient angioplasty procedures, 1,471,000 inpatient diagnostic cardiac catheteri-zations and 68,000 inpatient defibrillator implantations are performed. The direct and indirect cost of cardiovascular diseases for 2007 is approximately $431.8 billion. The occurrence of plaque rupture with subsequent microemboli of atherosclerotic and thrombolytic debris into small coronary vessels has been confirmed. Microinfarction results from microemboli that are shed following coronary interventions. The aims of this review are to: 1) detect heterogeneous microinfarction using viability imaging, 2) characterize the consequences of distal coronary microembolization on left ventricle function and perfusion and 3) illustrate the progress of non-invasive imaging modalities in assessing distal coronary microembolization.
A New Iterative Solution Method for Solving Multiple Linear Systems  [PDF]
Saeed Karimi
Advances in Linear Algebra & Matrix Theory (ALAMT) , 2012, DOI: 10.4236/alamt.2012.23004
Abstract: In this paper, a new iterative solution method is proposed for solving multiple linear systems A(i)x(i)=b(i), for 1≤ i ≤ s, where the coefficient matrices A(i) and the right-hand sides b(i) are arbitrary in general. The proposed method is based on the global least squares (GL-LSQR) method. A linear operator is defined to connect all the linear systems together. To approximate all numerical solutions of the multiple linear systems simultaneously, the GL-LSQR method is applied for the operator and the approximate solutions are obtained recursively. The presented method is compared with the well-known LSQR method. Finally, numerical experiments on test matrices are presented to show the efficiency of the new method.

Raymond Farah, Rola Khamisy-Farah, Jamal Awad
Open Journal of Internal Medicine (OJIM) , 2012, DOI: 10.4236/ojim.2012.24030
Abstract: We report a 43-year-old man who had been experiencing recurrent attacks of syncope for several years, and a search for the causes behind these lapses in consciousness was fruitless for many years. The patient was admitted to our department of internal medicine because of the symptoms flushing, hypotension and episodes of syncope. After a careful anamnesis and then a comprehensive investigation, we reached the definitive diagnosis of the infrequent disease “systemic mastocytosis”.

BMC Medical Genetics , 2007, DOI: 10.1186/1471-2350-8-67
Abstract: We studied three families from Saudi Arabia (Family A), Kuwait (Family B) and Yemen (Family C) with 19 individuals affected by CADASIL.The mean age of onset was 31 ± 6 and the clinical presentation included stroke in 68%, subcortical dementia in 17% and asymptomatic leukoariosis detected by MRI in 15%. Migraine and depression were frequently associated, 38% and 68% respectively. The mean age of death was 56 ± 11. All NOTCH3 exons were screened for mutations, which revealed the presence of previously reported mutations c.406C>T (p.Arg110>Cys) in two families (family A&B) and c.475C>T (p.Arg133>Cys) mutation in family C.CADASIL occurs in Arabs, with clinical phenotype and genotype similar to that in other ethnic groups.Cerebral autosomal dominant arteriopathy with subcortical infarct and leukoencephalopathy (CADASIL) is becoming the most common form of adult onset hereditary syndrome characterized by recurrent transient ischemic attacks (TIA) and strokes, leading to progressive dementia, migraine with aura and psychiatric disturbances [1-3]. Symmetrical white matter abnormalities are invariably seen, while small subcortical infarcts are often reported [4]. The extent of the MRI lesions increases with age. Atypical anteriopathy with electron-dense granular deposition in the media of small cerebral arteries underlies the pathology of this disorder [5]. This initial thickening and expansion of the extracellular matrix can be found to a lesser extent in extracerebral arteries, such as skin arterioles [6]. Mutation in the NOTCH3 gene is usually linked to CADASIL [1]. NOTCH3 encodes a 300-kd transmembrane protein with a receptor and cell signal transduction function. This receptor is expressed in vascular smooth muscle cells [7]. Mutations are almost always mis-sense mutations causing the loss or gain of a cysteine residue and are detected in over 90% of patients [8,9]. All mutations were located within the epidermal growth factor (EGF) repeats in the extracellular domain o
Time-Dependent Nonplanar Dust-Ion-Acoustic Gardner Double Layers  [PDF]
Farah Deeba, A. A. Mamun
Open Journal of Acoustics (OJA) , 2011, DOI: 10.4236/oja.2011.13009
Abstract: A theoretical investigation has been made on the nonplanar (cylindrical and spherical) dust-ion-acoustic (DIA) double layers (DLs) in a dusty plasma system, containing inertial ions, Boltzmann electrons, and negatively charged stationary dust. In this investigation, in order to analyze the time dependent nonplanar DIA DLs, we have used the modified Gardner equation, which has been obtained by employing the reductive perturbation method. It has been found that the behaviors of DIA DLs have been significantly modified by the time period and the nonplanar geometry. The nonplanar DIA DLs has been found to be similar with planar DIA DLs only at large time scale and the cylindrical DIA DLs have been found to be smaller than the spherical DLs, but larger than the planar DLs.

Hasibun Naher, Farah Aini Abdullah
Applied Mathematics (AM) , 2012, DOI: 10.4236/am.2012.310168
Abstract: The (G'/G)-expansion method is simple and powerful mathematical tool for constructing traveling wave solutions of nonlinear evolution equations which arise in engineering sciences, mathematical physics and real time application fields. In this article, we have obtained exact traveling wave solutions of the nonlinear partial differential equation, namely, the fourth order Boussinesq equation involving parameters via the (G'/G)-expansion method. In this method, the general solution of the second order linear ordinary differential equation with constant coefficients is implemented. Further, the solitons and periodic solutions are described through three different families. In addition, some of obtained solutions are described in the figures with the aid of commercial software Maple.
Digital Road Profile Using Kinematic GPS

Artificial Satellites , 2009, DOI: 10.2478/v10018-009-0023-6
Abstract: A Digital Road Profile (DRP) is a digital representation of road surface topography or terrain in the longitudinal direction. The need for accurate DRP is vital in two stages; before the road construction starts and after the road construction finished where the verification of its geometrical characteristics is essential for engineering safety purposes. Classical surveying techniques are traditionally used for the DRP generation with limitation of high-cost and time-waste. Kinematic DGPS or Real Time Kinematic DGPS positioning can provide accurate enough results for such application. This paper presents an assessment study of using kinematic GPS technique for DRP generation comparing with classical survey in south Egypt. The results shows that, vehicle-GPS system used in combination with post processing kinematic DGPS gave satisfactory accuracy for nearly all points for a distance of nearly 2 km. with max. and min. difference not more than 7.7 cm, a mean value of 0.10 cm and a Root Mean Square RMS value of 4.11 cm.
