This research aimed to measure the competitiveness of Egyptian orange exports to the Saudi Arabian and the Kuwaiti markets. The research used the descriptive and quantitative analysis tools that lead to achieving the goal of the research, which utilized some competitive measurable indicators such as market share, geographic concentration, the concentration of commodity for both markets. The results showed decline in the proportion of exports of Egyptian orange for both markets to drop from 3.44% for the Kuwaiti market and 23.28% of the Saudi market in 2009, reaching the order 2.28%, 18.22 for the two markets, respectively, in 2015, an average of 2.52%, 21.01% for the two markets, respectively, during the period of 2009 - 15.The results of the general time trend also showed demand for Egyptian orange dropped in both markets, while increasing the value of imports of orange to both markets during the study period. The results of the indicators to the high market share of Egyptian oranges in the Saudi market accounting for 52.01%, more than half of the Saudi market size, but for the Kuwaiti market represents the market share by the order of 34.3%, meaning that the Saudi market occupies first place for exports of Egyptian orange during the period 2009- 15 . By studying the geographical concentration of the Egyptian agricultural exports to the Gulf countries it was found that high up to the order almost half of the Gulf market increased by 49.02%, as well as the concentration of commodity to occupy Egyptian orange by 84.4% of the total GCC and occupies Saudi Arabia 3.10%, Kuwait 0.4%, this shows that the diversity of goods received for both markets thus, the study recommends the following: 1.The need to pay attention to these markets, and work to increase its agricultural exports, especially the Saudi market. 2.The need to restore the geographical distribution of Egyptian orange exports in the markets of the Gulf countries in order to achieve maximize the return of exports. Attention to the standard of quality specifications, and dates of export, the items sought to ensure the continuation of the exported quantities and work to increase it.

The present study was conducted to investigate the effect of replacement 20% of the total amount of the soybean meal (SBM) in the ration (equal 3.6%) with (5.2%) Moringa oleifera leaf meal, (MOLM) on growth performance, carcass traits, meat quality and blood constituents of growing New Zealand White (NZW) rabbits from 5 to 12weeks of age. A total 40 growing NZW rabbits 5 weeks aged and a body weight of 565±5 g and was divided to two experimental groups (20 rabbits in each group has been deployed to five replicates by 4 rabbits in each). The first group, fed the basal ration (zero% MOLM) a served as control, the second group fed diet contained 5.2% MOLM (replaced instead of 3.2% SBM, which represent 20% of the used total amount of SBM in the ration). Ration was iso - caloric and protein. Results were discussed and the most important results have summarized as follows: there is no differences in the final weight and weight gain of the rabbits at 12th week of age. The Results of carcass traits showed absence of significant differences in the weight of each of the blood, fur, kidneys, liver, heart, head, and the spleen between the two experimental groups. Also no significant differences were recorded for the meat components (moisture, protein, fat, fiber and carbohydrates) between the two groups. As well as there were no significant differences in the assessment of blood constituents, whether for rabbits fed moringa or control group in each of total protein, albumin, globulin, GPT, GOT, creatinine, uric acid, glucose, hemoglobin, red blood cells, white blood cells, blood platelets. No Specific direction was observed to distinguish any of the two groups, The obtained results showed that the highest economic efficiency was (88.28%) for the second group which fed diet contained 3.2% MOLM, while, the first group (control) was (81.47%) respectively. Conclusively,it can be concluded that, Moringa Leaf Meal (MLM) can be used safely in feeding NZW rabbits to alternate a part of rabbit food (Soybean meal) with untraditional food in Egypt such as (Moringa oleifera Leaf Meal) without any adverse effect on the growing, slaughter test, meat quality and blood characteristics.

A 6 x 6 half diallel was conducted at the Experimental Farm, Faculty of Technology and Development, Zagazig University, Egypt., during the two successive growing seasons 2013/2014 and 2014/2015. The fifteen crosses along with their parental genotypes (Gemmeiza 11 (P1), Sids 12 (P2), Giza 168 (P3), Sahel 1 (P4), Line 18 (P5) and Line 26 (P6)), were evaluated to estimate gene action effects for grain yield and its components.Mean performance of wheat parental genotypes and their F1 crosses for grain yield and its components exhibited significant differences for all studied characters. The parental genotypes Gemmeiza 11, Sahel 1 and Giza 168 gave the highest productivity for grain yield/fad. Regarding the F1 crosses (P3×P5), (P2×P3), (P1×P2) and (P1×P6), they gave the highest productivity for grain yield/fad. On the other hand, the parental genotypes Line 18 (P5) and Line 26 (P6) and F1 crosses (P1 × P3) and (P2 × P4) exhibited the lowest values in grain yield/fad. The results showed thatsignificant values of additive (D) and dominance (H1 and H2) for all characters, except 1000-grain weight and grain yield/fad., revealing the importance of both additive and non-additive gene action in the inheritance. The dominance genetic effects (H1 and H2) were more than the additive gene effects (D), fornumber of spikes/plant,spike grain weight (gm.), grain yield/plantand grain yield/fad., showing that these characters were controlled by dominance gene action and could be improved through hybrid breeding method. But the additive gene effects (D) were more than non-additive gene effects (H1 and H2) for number of spikelets/spike, number of grains/spike and 1000-grain weight, showing that these characters is controlled by additive gene action in these characters. Narrow sense heritability estimates were high for number of spikelets/spike (61.256 %) and number of grains/spike (56.584 %).

Field studies on residues and dissipation of lambda-cyhalothrin in green pepper fruits were conducted during 2016. Residues were quantified at different harvest intervals of (2h), 1, 3, 6, 9, 12 and 15 day after insecticide application. Persistence, dissipation, half-life value and safe harvest interval of the insecticide in green pepper were calculated. Results revealed that, loss percentages of initial deposits were higher in sweet pepper fruits than leaves. The half-life (t½) values of lambda-cyhalothrin 2.68 and 3.45 in green pepper fruits and leaves, respectively.
Data indicated that pepper fruits could be consumed safely after 6 days of treatment with lambda-cyhalothrin. Thepre harvest interval (PHI) value was reduced to two hours after spraying with washing the fruits with 1% sodium carbonate or frying the fruits in boiling oil when comparing with themaximum residue limit (MRL) (0.01 mg/kg). While pickling process was, however, don’t alter this value. Lambda –cyhalothrin residues significantly decreased the levels of the all tested quality parameters (total soluble sugar, glucose, acidity, total soluble solids, ascorbic acid, β-carotene, and protein) in pepper fruits throughout the experiment with the exception that the dry matter. Lambda -cyhalothrin residues were significantly reduced the levels of N %, P %, K %, iron mg/kg, manganese mg/kg, calcium % and zinc %.
Conclusively, results clearly revealed that thePHI value (6 days) was reduced to two hours after spraying with washing the fruits with 1% sodium carbonate or frying the fruits. Lambda -cyhalothrin residues were significantly reduced the levels of some quality parameters and elements.

The p7-transactivated protein of Hepatitis C virus is a small integral membrane protein of 127 amino acids, which is crucial for assembly and release of infectious virions. Ab initio and comparative modelling, is an essential tool to solve the problem of protein structure prediction and to comprehend the physicochemical fundemental of how proteins fold in nature. Only one domain (1-127) of p7 had been predicted using the systematic in silico approach, Threa Dom. I-TASSERwas ranked as the best server for full-length 3-Dprotein structural predictions of p7 where the benchmarked scoring system such as C-score, TM-score, RMSD and Z-score are used to obtain quantitative assessments of the I-TASSER models. Scanning protein motif databases, along with secondary and surface accessibility predictions integrated with post translational modification sites (PTMs) prediction revealed functional and protein binding motifs. Three protein binding motifs (two Asp/Glutamnse, CTNNB1-bd_N) with high sequence conservation and two PTMs prediction: Camp_phospho_site and Myristyl site were predicted using BLOCKS and PROSITE scan.
These motifs and PTMs were related to the function of p7 protein in inducing ion channel/pore and release of infectious virions. Using SCOP, only one hit matched protein sequence at 71-120 andwas classified as small proteins and FYVE/PHD zinc finger super family.
Integrating this information about the p7protein with SCOP and CATH annotations of the templates facilitate the assignment of structure–function/ evolution relationships to known and newly determined protein structures.

Hepatitis C Virus (HCV) infection is a serious cause of chronic liver disease worldwide with more than 170 million infected individuals at a risk of developing significant morbidity and mortality. Till date there is no effective drug for the treatment or vaccine to prevent this infection. The present study aims in discovering novel inhibitors which target an allosteric binding site of P7-transactivated Protein1 of HCV. Virtual screening uses computer-based methods to discover new ligands on the basis of biological structures. A structure based virtual screening of Zinc database by computational docking and the post docking analysis of energy calculations and interactions followed by ADMET studies were conducted. The approach adopted was receptor-based.
Docking screens, guided with contact pharmacophores and neural-network activity prediction models on all allosteric binding sites and MD simulations, constituted our analysis workflow for identification of potential hits. Steps included: 1) Using two phases docking screen with moe and Glide Xp programs, 2) Ranking based on scores, and important H interactions. From the final hits, we selected best 10 compounds for further anti-HCV activity and cellular cytotoxicity assay. All 10 compounds have more potential to be considered as lead compoundsto inhibit ion channel activity of p7 with docking score and binding energy (E_score) values ranging from -16.5087 to -15.8089 and all these compounds displayed no cellular cytotoxicity. Finally, 10 hit compounds of different scaffolds having interactions with important active site residues were predicted as lead candidates. These candidates having unique scaffolds have a strong likelihood to act as further starting points in the optimization and development of novel and potent p7 ion channel inhibitors.
