The Sensitivity of Computerized Tomography in Diagnosis of Brain Astrocytomas  [PDF]
E. Abd Elrahim, A. Elzaki, Ali Hassan, A. M. Abd Elgyoum, H. Osman
Open Journal of Radiology (OJRad) , 2014, DOI: 10.4236/ojrad.2014.44040
Abstract: Astrocytomas are tumors that arise from astrocytes—star-shaped cells that make up the “glue-like” or supportive tissue of the brain. Astrocytomas can appear in various parts of the brain and nervous system, including the cerebellum, the cerebrum, the central areas of the brain, the brainstem and the spinal cord. The main objective of this study was to detect the sensitivity of the CT scan in diagnosis of the brain astrocytoma, in patients who were confirmed as brain gliomas using computerized tomography of the brain versus brain tissue biopsy after surgery. One hundred and one patients were included in this study. Bio-data collected for these patients (age, gender), radiographic appearance, contrast enhancement and the site of the tumor, were statistically analyzed. Out of the 101 patients with brain gliomas, 52 (51.5%) were male whose ages ranged between 1 and 80 years, and 64 (63.4%) cases were diagnosed as astrocytoma by CT. This study concluded that the CT brain was sensitive in the diagnosis of brain astrocytomas.

Abstract: The objectives of this study were to produce and evaluate sorghum-based infant food using cooking and drum drying methods. The product was made from sorghum flour, pigeon pea flour, milk, vit. C and other ingredients. The cooked materials were then drum dried. The dried product was found to provide adequate amounts of protein (15.15%) and energy values (414.25 Kcal/100 g DM) capable to meet the international standards for infants protein quality as recommended by the FAO/WHO/UN (1985). The protein digestibility was found to be improved by cooking and drum drying. The produced sorghum-based infant food physical and functional properties tested showed that the product has low water retention capacity and low viscosity. When comparing the prepared sorghum-based infant food with the commercial infant foods available in the market, this product proved to provide more protein and energy value. In conclusion the use of decorticated sorghum and pigeon pea flours in infants food, produced a product with high nutritional value and of better functional properties.
Reishi Mushroom Attenuates Hepatic Inflammation and Fibrosis Induced by Irradiation Enhanced Carbon Tetrachloride in Rat Model  [PDF]
Omama E. El Shawi, Sahar S. Abd El-Rahman, Marwa Abd El Hameed
Journal of Biosciences and Medicines (JBM) , 2015, DOI: 10.4236/jbm.2015.310004
Abstract: This work was undertaken to establish a new experimental model of hepatic fibrosis by gamma irradiation and CCl4 and to study the hepatoprotective effect of Reishi Mushroom (RM) against hepatic fibrosis induced in that model. Our results revealed that oral co-administration of 110 mg/kg RM by gavage to fibrotic rats offered an obvious hepatic protection as assured by the significant decrement in ALT and AST, HP content, MDA and NO levels with elevation of the antioxidant enzymes activities. The levels of TGF-β, TNF-α, HO-1 and type-1 collagen and their m-RNA expression were markedly declined as compared with those of fibrotic rats. Microscopical examination revealed that the exposure of rats to radiation aggravated the effect of CCl4 causing extensive collagen deposition and marked pseudolobulation of the hepatic parenchyma indicative of bridging fibrosis. While, oral co-administration of RM obviously improved the state of steatosis and apparently suppressed hepatic fibrogenesis.

Abstract: During this study, the principal aim carried out was to obtain more information about technique and conservation conditions of the Egyptian wall paintings during the Roman period in the funerary house in necropolis of Tuna el-Gabal, El-Minia-Upper Egypt. It’s going back to 2nd century AD and involves different sites of Ptolemaic and Roman chapels; some are in the immaculate established style while others are a blend of Pharaonic-Greek style and both are secured with mural painting. Deterioration problems observed on the wall paintings of the funerary house are, loss of plaster layers, disintegration of plaster layers, loss of paint layers (blistering and peeling), discoloration and severely damaged owing to a lot of deterioration factors as weakness of mud brick support, deterioration of surface treatments and to the widespread presence of different salts. The materials used in the painting, preparation layers and the state of conservation of the mural painting at funerary house were investigated by integrated physio-chemical measurements, particularly micro-Raman spectroscopy (µRaman), light optical microscopy (LOM), scanning electron microscopy (SEM) coupled with an energy dispersive X-ray analysis system (EDX), X-ray powder diffraction (XRD) and Fourier transform infrared (FT-IR). In addition, the morphology of multilayer plaster from wall painting was investigated using atomic force microscopy (AFM). A wide color palette utilized as a part of the necropolis has been identified with mineral pigments and pigment mixtures. It is found that, the paints were based on an organic binder and traditional pigments (azurite, hematite, ochre, vegetable black) were used as colorants on plaster. The examination demonstrated that the preparatory layer is verging on made of pure lime while the plaster layer based mainly of lime and gypsum with variable amounts of quartz. The obtained results provided information about the painting technique, chemical composition, crystal structure in addition to the stratigraphy of the paint layers and the state of preservation and on the causes of the painting deterioration. Furthermore, the obtained results can be used in the conservation and restoration interventions of these sites.

International Journal of Geosciences (IJG) , 2012, DOI: 10.4236/ijg.2012.32038
Abstract: A set of five satellite images from the Landsat satellite, Moderate Resolution Imaging Spectroradiometer (MODIS) and the Shuttle Radar Topography Mission (SRTM) sensors has been operated to analyze land cover and topography of the Hail region, Saudi Arabia. Image processing techniques included unsupervised classification for clustering four land cover units in the MODIS image, namely: plains, sand dunes, mountains, and cultivated lands. The SRTM image was classified to produce a thematic topographic map with 100 m elevation interval. The normalized difference vegetation index (NDVI) was applied in the Landsat images as a proxy to the change of agricultural land in Hail between 1972 and 2000. Results showed that Hail region occurs at a high plateau. Minimum elevation occurs at its northeastern corner and peaks occur at the southwestern side. The surface area of Hail is estimated at 115,690 km2. The majority of Hail area is represented by plains and sand dunes. Cultivated lands increased from 9500 ha in 1972 to 139,000 ha in 2010.

Egyptian Journal of Hospital Medicine , 2011,
Abstract: To evaluate the role of procalcitonin (PCT), high senstive C-reactive protein (hs-CRP) and Interleukin-6 (IL-6) for prediction of subclinical intrauterine infection in pregnant women with preterm premature rupture of membranes. Methods: Twenty patients with preterm premature rupture of membranes PPROM (study group) and twenty apparently healthy pregnant women (control) group between 26-34 weeks of pregnancy were enrolled in this study. In all cases analysis of serum procalcitonin by high performance liquid chromatography, Il-6 by ELISA method and hs-CRP by nephelometry were done. Culture of vaginal bacteria was done for study group only. Results: Procalcitonin levels in the PRROM group were significantly higher than in healthy pregnant women (median 1.95 versus 0.39-Interquartile range 1.375 versus 0.213 - P0.001). A significant correlation was observed between PCT and hs-CRP (r=0.510; P0.031) and leucocytosis (r=0.544- P 0.013). Also IL-6 levels were significantly higher in cases of PPROM compared with control group (median 40.01 versus 5.55 - Interquartile range, 45.88 versus 4.22 P 0.001). No significant correlation was present between PCT and IL-6 Conclusion: Determination of PCT, hs-CRP and IL-6 in mother's blood sample can be useful for diagnostics of PPROM cases suspected of intrauterine infection. However PCT more valuable and specific.

E.A. Abd El-Lattief
Asian Journal of Crop Science , 2011,
Abstract: A two years field study was conducted to evaluate the effect of response of two sweet sorghum cultivars to different sources and time of nitrogen application during 2009 and 2010 at experimental farm Faculty of Agriculture, South Valley University at Qena Governorate, Egypt. Two cultivars viz. Tracy and Honey and six combination of source and application time of nitrogen fertilizes viz. ammonium sulphate, 20.5% N in two equal doses (T1) and in three equal doses (T2), ammonium nitrate, 33.5% N in two equal doses (T3) and in three equal doses (T4), urea, 46.5% N in two equal doses (T5) and in three equal doses (T6) were tested in the study. The experiment was laid out in split plot design with cultivars in main plots and nitrogen fertilizers in sub-plots. Among sweet sorghum cultivars, cv Honey had the highest stalk height, stalk diameter, number of internodes per stalk, Brix value, sucrose content, apparent purity percentage and stalk and forage (leaves) yields and lowest reducing sugar content. Application of T4 gave the highest value of the above measurements and lowest reducing sugar content. Cultivar and nitrogen treatments interaction was significant on stalk and forage yields as well as reducing sugar content. The highest stalk and forage yields and lowest reducing sugar content were obtained by planting cv Honey and application of ammonium nitrate in three equal doses (at planting , 4 leaf stage and booting). Plant height, stalk diameter, forage yield, brix and sucrose were positively and strongly correlated with stalk yield.

Asian Journal of Crop Science , 2011,
Abstract: Sowing methods and seeding rate play an important role in the placement of seed at proper depth and stand establishment of the growing crop which ultimately affects crop growth and productivity. This study was conducted for 2 seasons to establish optimal sowing method and seeding rate for bread wheat (Triticum aestivum L.) in sandy-loam soil. The study aimed at achieving high yield and profit. A field experiment was conducted using a randomized complete block in split plot design with three planting techniques (hilling in ridges, drilling in rows and broadcasting) and four seeding rates (100, 125, 150 and 175 kg ha-1) as the main plot and split plot, respectively. Results revealed that all yield and yield parameters were significantly affected by the sowing method and seed rate, while grain protein content was non-significant by these factors. The interaction of sowing method and seed rate significantly affected the number of effective tillers m-2, weight of grains spike-1, grain and straw yields ha-1 and harvest index. Wheat sown by drilling method at the seed rate 150 kg ha-1 gave the highest values of grain and straw yields ha-1 and harvest index and this treatment was found to be most economical. Based on these results, it is recommended to sow 150 kg ha-1 seeds by using drill method for planting bread wheat Giza 168 cv under similar soil and climatic conditions. Correlation coefficients analyses revealed positive significant relationships between grain yield and plant height, effective tillers m-2, grain number spike-1, straw yield and harvest index.

Asian Journal of Crop Science , 2012,
Abstract: Seed and oil yields, their components and the relationships among yield and related traits were measured in 25 safflower (Carthamus tinctorius L.) genotypes, under arid conditions. The studies were conducted in sandy-loam soil at the experimental farm of Faculty of Agriculture, South Valley University, Qena, Egypt, during two seasons, 2009-10 and 2010-11. The trials were laid out in randomized complete block design with three replications. Significant differences were observed at 1% probability level in plant height, number of branches and capitula per plant, 1000-seed weight, weight of seed per plant, oil content and seed and oil yields among the genotypes. The Line-1682 produced the highest plant height (199.7 cm), number of branches plant-1 (9.000) number of capitula plant-1 (25.69), weight of seed plant-1 (39.46 g), seed yield (2846 kg ha-1), seed oil content (36.50%) and oil yield (1039 kg ha-1), while Line-1687 produced the highest 1000-seed weight (49.13 g). The lowest values for above mentioned traits were obtained from Line-1679 except the lowest 1000-seed weight resulted from Line-1671. Oil yield expressed firm correlation with, plant height (r = 0.566**), branches per plant (r = 0.591**) capitula per plant (r = 0.625**), seed weight per plant (r = 0.863**), seed yield (r = 0.990**) and seed oil content (r = 0.711**).
