Abstract: The Egyptian government introduced wheat-flour fortification with iron and folic acid to reduce the incidence of neural tube defects, but suspended it for technical reasons. We previously developed novel legume foods with enhanced folate content. In this study, we investigated the efficacy of 12-week intervention with folate-enhanced foods versus folic acid supplement in improving folate status in Egyptian women. A randomized, parallel intervention trial with two active groups (n = 19, n = 18) and one blinded control group (n = 20) was executed over 12 weeks. Volunteers received either germinated legume foods and orange juice (≈250 μg/d folate) or folic acid supplement (500 μg/d) or apple juice (0 μg/d folate). Folate status was assessed by erythrocyte and plasma folate and total homocysteine (tHcy) at day 0, and after 8 and 12 weeks of intervention. After 12 weeks, mean plasma folate increased by 14 (P < 0.0001) and 12 (P < 0.0001) nmoL in the folic acid and food group, respectively. Erythrocyte folate concentration increased in the folic acid group from 614 to 912 (P < 0.0001) and in the food group from 631 to 914 nmoL (P < 0.0001). After 12 weeks, 90% of subjects in the folic acid group and 70% in the food group had erythrocyte folate concentrations exceeding 906 nmol/L. tHcy concentration was decreased by 20% (P = 0.007) and 18% (P = 0.006) in the folic acid and food group, respectively, but remained unchanged in the control group during intervention. Folate-enhanced foods effectively improve folate status in women of reproductive age. These foods could be used as a complement to folic acid fortification.

Abstract: Multi-detector row computed tomography urography (MDCTU) becomes the imaging modality of choice for evaluation of the kidneys and urinary tract. The aim of this study was to discuss and illustrate the role of MDCTU, on a 32-row CT scanner in the evaluation a variety of entities that were frequently associated with microscopic hematuria in adults. This prospective cohort study was performed in the period of August 2013 to October 2014. Fifty positive participants to microscopic hematuria were examined at the radiology department of Alnilin Diagnostic Medical Center and Antalya Medical Center. Computed tomography urography (CTU) scanning was performed using two powerful performances, high speed multi-detector row on 32-row CT scanners (Siemens Healthcare Global, Somatom Emotion Duo Eco). Statistical analysis was done through the standard Statistical Package for the Social Sciences (SPSS Inc., Chicago, IL, USA) version 15 for windows. MDCTU established the correct cause of microscopic hematuria in (44; 88%) of participants. In (6; 12%) of participants, no cause of hematuria was identified based on the standard of references. The causes of hematuria in (41; 82%) participants were diseases in the upper urinary tract, while urinary bladder neoplasms (2; 4%) and diverticulum (1; 2%) were the causes of hematuria (3; 6%) in the lower urinary tract. Thirty two-row MDCTU scanner demonstrated satisfactory results in the investigation of microscopic hematuria, being able to demonstrate a wide spectrum of diseases affecting the urinary tract is the main advantage of the technique.

Abstract: Condensation of D-glucose, o-phenylenediamine and N,N-benzylphenylhydrazine hydrochloride (NNBPHH) in a one-pot reaction, or condensation of 2-(D-arabino-tetritol-1-yl) quinoxaline and NNBPHH, gave 3-(D-erythro-glycerol-1- yl)-1-phenyl-1H-pyrazolo[3,4-b]quinoxaline. The structure of the latter was determined by 1H NMR spectroscopy and by synthesis using phenylhydrazine hydrochloride instead of NNBPHH. Condensation of D-glucose and 4,5-dichloro-o-phenylenediamine gave 6,7-dichloro-2-(D-arabino-tetritol-1-yl)quinoxaline, which upon condensation with NNBPHH gave the corresponding 6,7-dichloro-3-(D-erythro-glycerol-1-yl)-1-phenyl-1H-pyrazolo[3,4-b]quinoxaline. The structure and mechanism of formation of these compounds are discussed.

Background: Laparoscopic tension-free repair of inguinal hernia was presented in 1990s, promising less pain and short recovery period, but carrying the risk mesh bulging and migration. Objective: We have presented our technique in which central zone of mesh is fixed only after closure of hernial defect. Patients and Methods: This study included 27 males patients (14 indirect inguinal hernias, 9 direct inguinal hernias, 4 both direct and indirect inguinal hernias on the same side). These cases are undergoing tension-free mesh repair after closure of hernial defect, and the mesh is fixed only at its central zone using Gulbran 2, between April 2011 and March 2013. The follow-up period ranged from 6 to 30 months. The intra and postoperative complications were recorded. Results: Mean hospital stay was 1 day. The age of this group of patients ranged from 23 to 63 years (mean, 47 years). The operative time ranged from 30 to 100 minutes (mean, 45 minutes). The intraoperative complications were in form of mild bleeding in 7 patients (25.9%) during hernial sac dissection. Postoperative complications were mild inguinal pain in 4 patients (14.8%) for three weeks. Mild hydrocele in 3 patients (11%) was recorded. No recurrence or bulging at hernia site was noticed during the period of follow-up. Conclusion: Laparoscopic inguinal hernia repair with central mesh fixation after closure of hernial defect is effective, easy and free of complications.

Abstract: Abstract: The aim of this study was to develop a cheap, locally made and friendly applicable phantom for gamma camera quality control and to test its validity relative to standard results (intrinsic and extrinsic spatial linearity and intrinsic and extrinsic uniformity) of gamma camera SPECT. And the significance of this experimental study was to introduce a multi-purpose phantom for gamma camera which could overcome the risk accompanied by quality control test procedure such as detector crystal damage and the appearance of moiré patterns. The results of the developed phantom showed an average count difference of 0.7% relative to the standard phantom and about 4% in X- to Y-axis directions relative to the standard phantom. Also, the measured absolute linearity was 0.63 mm in X direction and 0.64 mm in Y direction for the UFOV compare with 0.70 mm value of acceptance test. And the I.U. and D.U. of the developed phantom were 3.18% and 2.27% respectively for the UFOV relative to the standard phantom I.U. and D.U. (2.0% and 1.5%) for the UFOV respectively.

Journal of Applied Sciences , 2007,
Abstract: This research presents a Digital Signal Processor (DSP) based prototype instrument to provide real-time detection of power disturbances that can be used to perform quick power quality monitoring. The proposed instrument uses the Texas Instrument TMS320C6711DSP starter kit (DSK) with a TI ADS8364EVM 250-kHz, 16-bit, 6-channel analog digital converter mounted on the daughter card. For real-time detection of power disturbances, the continuous wavelet transform is used to detect different types of disturbances such as voltage sag, swell, transient, interruption and harmonics. The results of analysis show that the implementation of continuous wavelet transform algorithm in DSP-based system provide accurate and fast detection of power disturbances.

Abstract: Wheat (Triticum aestivum L.) flour represents one of the primary sources of calories and proteins for the human diet. The increase in the wheat yield without losing its baking and milling quality is an important breeding objective. The use of QTL analysis is an expedient methodology to help breeders to face this multifaceted challenge. Here, a population of 129 recombinant inbred lines (RILs) developed from a cross between ‘Steele-ND’ cultivar and ‘ND 735’ advanced line was used to evaluate several yield and quality traits and map the genomic regions controlling these traits. The phenotypic data were collected from field experiments conducted at four North Dakota (ND), USA environments. Transgressive segregation was observed for all traits, with RILs outperforming the most adapted parent and commercial cultivars. Using a linkage map of 392 markers, composite interval mapping identified a total of 13 environment-specific QTLs, all explaining large phenotypic variations (R2=16-44%). The genotypic values of these “reserve” alleles were directly used as criteria of selection in breeding programs.

Abstract: Pulmonary Hypertension (PH) is an increase of blood pressure in the pulmonary artery, pulmonary vein, or pulmonary capillaries, together known as the lung vasculature, leading to shortness of breath, dizziness, fainting and other symptoms, all of which are exacerbated by exertion. Pulmonary hypertension can be a severe disease with a markedly decreased exercise tolerance and heart failure. The aim of this study is to evaluate the effect of sildenafil versus nifedipine in the treatment of pulmonary hypertension in children. The study was carried out on 30 pulmonary hypertension patients (15 males and 15 females), 1 month to 10 years old and their weights ranged from 4 to 28 kg; from outpatient pediatric cardiology clinic at Bani suef university hospital; Patients were divided into two equal groups. Group (A) received sildenafil in a dose of 0.1-1 mg/kg/dose every 8 h orally and group (B) received nifedipine in adose of 0.5-3 mg/kg/dose every 8-12 h orally. Patients were treated and followed for 6 month. They were represented to full history taking, clinical examination, Echocardiographic examination in the beginning and every 6 months of the study. there was an improvement in general health of children after therapy and in respiratory rate, decreasing in pulmonary artery pressure in both groups but, the decrease in P.A.P in group A is greater than group B and the improvement in H.R in group A is better than group B So, we concluded that usage of sildenafil in children with pulmonary hypertension either primary or secondary is better and more effective than usage of nifedipine.

Abstract: Increased pollution levels have caused damage to our planet. Many scientists are now warning on the long term effects. Green houses gases causes more of the sunlight to be trapped within the Earth’s atmosphere and thus causing increased Earth temperature. Individuals, governments, and private entities are now acting on fixing this problem. One of the most promising solutions is installing an array of solar cells in residential areas. Doing so makes sense for areas with abundant sunlight as the dependency on the grid can be minimized and even completely illuminated while providing a feasible economic perspective at the same time. This paper presents the modelling of a residential setup as a complete system along with an electric vehicle. The modelled components include: Photovoltaic Cells, Home Load Usage, Electric Vehicle, High-Voltage battery as an energy storage, Boost, and Inverter. The presented analysis will help engineers and system designers do better cost analysis. The study can also be used as a basis for maximizing the solar energy usage and perform component optimization.
