Screening for HCV antigens presents an alternative marker to viral antibodies and RNA. Thus, this work aimed to detect HCV-E1 antigen level in different liver fibrosis stages and to evaluate the possible relationship between this level and the disease severity. The study was performed among one-hundred and forty one participants categorized into two groups (35 healthy individual and 106 chronic hepatitis C patients). All involved patients were recruited from Tropical Medicine Department, Mansoura University Hospitals, Mansoura, Egypt. HCV-E1 antigen was identified using western blotting and its level was quantified by ELISA. Fibrosis was staged according to METAVIR scoring system as the following: patients with fibrosis stage F1: 32.1% (34/106) of cases, F2: 29.2% (31/106) of cases, F3: 20.8% (22/106) of cases and F4: 19.7% (19/106) of cases. HCV-EI was identified at 38 kDa using their respective specific monoclonal antibody. HCV-EI antigen level (OD) significantly increased (P> 0.0001) with liver fibrosis progression, it was 0.77±0.27, 0.55±0.17,0.43 ±0.16, and 0.30 ±0.09, in F4, F3,F2, and F1;respectively.  HCV-EI antigen level seems to be associated with progression of HCV infection.

The first experiment was normally irrigated four times at different stages, the second one irrigated only once at tillering stage. The main results can be summarized as follow ; the water stress treatment decreased the means of flag leaf area (FLa), flag leaf angle (FLang), transpiration rate (TR), number of spikes/plant (NS/P), number of grains/spike (NK/S), 1000–grain weight (100-GW) and grain yield/plant (GY/P) for parents and their hybrids. The means of stomatal resistance (SR), chlorophyll a/b ratio (Chl a/b) and leaf temperature (LT) was increased under water stress. Irrigation mean squares were significant for all studied traits, indicating that the two irrigation regimes behaved differently for these characters. In addition, mean squares due to genotypes were highly significant for all traits except for FLA under  stress condition. Mean squares of combining ability were highly significant for almost of all the studied traits under the two environments and their combined,  indicating the presence of both additive and non additive types of gene effects in the genetic system controlling of these traits.

The obtained results indicated that: Cutoff irrigation received the lowest amount of irrigation water and drain discharge rates. Cumulative amounts of drainage water were lower with cutoff irrigation than that observed under traditional irrigation. N-fertilizer application in two and three doses especially, with cutoff irrigation resulted in moderate increased of soil NO3- content after every dose and slightly decreased after the followed irrigations while, one dose application resulted in the highest values of NO3- content in the soil and rapidly decreased after the followed irrigations. N-fertilizers application in two or three doses resulted in decrease of nitrate concentration and losses in drainage water than the addition of one dose especially, under cutoff irrigation. The estimated losses of NO3- or N-NO-3 in drainage water were increased when addition of N-fertilizer in one dose than two and three doses by 12.42 and 16.51% in the first season of study and 13.33 and 16.54 % in the second season, respectively under cutoff irrigation. The corresponding percentages were 19.02 and 22.04% in the first season and 19.12 and 22.88 % in the second season, respectively under traditional irrigation.

(Vicia faba L.)  cv.  Sakha 3 and Maize (Zea mays single hybrid crops cv.  Giza 10) plants were investigated in lysimeter experiments at Sakha Agricultural Research Station Farm during summer 2017 and winter 2017/2018 seasons, respectively. Results of soil properties indicated that there are no variations among soil salinity and different foliar application treatments with nano-silica. While, there is a remarkable variation in mean of soil salinity among  irrigation with fresh water and blended with well water treatments, which arranged T4 (1.36 dS m-1), followed by T3 (1.85 dS m-1), compared with T2 (2.45 dS m-1), at 0-20 cm depth for studied plants. A similar trend was also exhibited in the other soil depths. But, exchangeable sodium percentage of the different soil depth unaffected under the same plant.  Maize and Faba bean roots and leaves anatomical structure were cleared that at 300 mg L-1 N-Si, roots diameter changed up to (22.75, 15.54 and 3.93, 5.97 %) of Maize and Faba bean respectively, diameter of vascular cylinder (7.95, 6.33 and 1.84, 2.96 %), and thickness of cortex (22.77, 6.02 and 2.90, 1.69 %) with T1 and T4 treatments compared to the control, respectively. The highest values of big vessel diameter arch-1 were recorded for roots of Faba bean (95.14 and 55.50 %), with T1 and T4 treatments compared to control. Also, anatomical structure of maize leaves attained 13.80 and 10.43 % for lamina thickness, 16.52 and 4.65 % for midrib length and 7.82 and 31.92 %, for number of vesicular bundle midrib-1 at 300 mg L-1 N-Si with T1 and T4 treatments more than the control. Also, under the same conditions, mesophyll thickness and midrib length of faba bean leaves recorded 20.07, 51.41 %, and 35.65, 103.89 %, respectively moreover these results will be positively reflected upon chlorophyll content.For productivity, results showed that T4 treatment attained the highest values 4.22, 5.32 t/ fed. and 1.74, 1.84 t/fed.in grain and straw yield of Maize and Faba bean plants, under foliar application with 300 mg L-1 of nano-silica compared with other concentrations, respectively. From these results, recommended that foliar application with 300 mg L-1 of nano-silica is the better concentration to mitigation of salt stress effect as well as improvement soil properties, anatomical structure and productivity of Maize and Faba bean plants.}, keywords = {Nano-silica,salinity,Maize,Faba bean,Anatomical structure,soil propertis,productivity}, url = {https://jpp.journals.ekb.eg/article_36610.html}, eprint = {https://jpp.journals.ekb.eg/article_36610_0ffb4b58f813c85652d180024fd18728.pdf} }
