Salinity is one of the stress factors creating agricultural disturbance, nearly 20% of the world’s cultivated land is lost to it. Therefore, there is a need to investigate various nitrogen forms for their ability to suppress salt-stress to a minimal level. This study aimed at investigating Telfairia occidentalis Hook F for its response to salt stress and foliar nitrogen supply. A greenhouse pot experiment in a completely randomized design was conducted at Olabisi Onabanjo University. Growth parameters were studied over a period of 4 weeks and plants were subjected to 5 days of stress in the following combinations: Category 1 (C1) which served as the control received 500mls of daily watering, category 2 (C2) received 500mls of 0.1M NaCl, category 3 (C3) received 500mls of 0.1M NaCl and 100mls of 0.025M NH4NO3, category 4 (C4) received 500mls of water and 100mls of 0.025M NH4NO3. Water or NaCl was given to C2 to C4 every 5 days except NH4NO3 which was sprayed weekly. There was significant difference between the control and other treatment categories. The physiological response shows that 0.1M NaCl is a lethal dose because it led to reduction in growth parameters and eventual death of all the plants. However, only a plant survived in C2, while NH4NO3 suppressed salt effect in C3, C4 performed better with increased growth features close to the control. Further research should be carried out on the specific concentration of NH4NO3 required including its mechanism of action

: This study aims to elevate the physiological biochemical composition of Jatropha curcas L. via irrigation by the nutrient rich treated sewage water or sewage water + sludge. At the same time, it might be considered as a steppingstone for the solution of the huge amount of sewage water that lost daily at the Drinking and Sewage Water Treatment Station in Al-Gabal Al-Asfar, Cairo, Egypt. Jatropha curcas is one of the best candidates of biodiesel production since its seeds contain oil which is practically participating in biodiesel production. In addition, its seed cake (a waste by-product produced after oil extraction) contains considerable percentages of cellulose, hemicellulose, and starch. The results cleared that, irrigation by sewage water and sewage water + sludge have been increased the levels of photosynthetic pigments (chlorophyll (a), chlorophyll (b) and carotenoids) and antioxidant enzymes [super oxide dismutase (SOD), catalase (CAT), poly phenol oxidase (PPO) and peroxidase (POX)] in the plant leaves. proline, and lignin in addition to total phenols have been increased in leaves and seed cakes of Jatropha curcas plants under irrigation by either sewage water or sewage water + sludge.

The objective of this study was to explore the effect of seed nanopriming with ZnONPs on the biomass accumulation, nutrient elements content, activity and gene expression of enzymatic antioxidants in shoots and roots of wheat plant. Maximum promontory response with respect to shoot and root biomarkers was shown in lower ZnONPs level (100 mg L-1), meanwhile at higher concentration (800 mg L-1) there was a marked suppression of growth biomarkers. Nanopriming with lower ZnONPs concentrations insignificantly changed the elements content in the shoots and roots and their transportation factors (TF). Conversely, the elements content and their transportation from root to shoot under higher ZnONPs treatments were significantly decreased compared to the untreated control. Zn content in the shoots and roots was markedly increased in a concentration dependent trend. Seed nanopriming enhanced the activity of SOD, CAT and APx in the shoots and roots, however CAT and APx activities in the roots were markedly decreased at higher ZnONPs levels but the attained values were significantly higher than the control. The expression of SOD, CAT and APx genes was markedly up regulated in response to nanopriming with ZnONPs. This expression showed different response according to the ZnONPs concentrations and plant organs. The results suggest that the ZnONPs stimulatory and phytotoxicity effects may be attributed to the concentration of released Zn ions from ZnONPs in the plant tissues.

The present study aimed to evaluate the impact of the long-term treatment with a combination of Spirulina platensis (Sp), Ganoderma lucidum (Gd), silymarin (Sil), and green tea (Gt) in HCV patients. Forty-five adult males (M) and females (F) HCV patients elderly 40 to 65 were involved in this observational study. HCV patients were divided into 4 subjects; subject-1 included 15 HCV patients (10M and 5F) and was administered with INF/Rib for 12 months. Subject-2 contained 7M plus 3F dealt with Sp, Sil, and Gt. 10 HCV patients concerned in Subject-3 (7M and 3F) and handled with Sp, Sil, Gd, and Gt. Subject-4 covered 10 HCV patients (6M and 4F) who received Sp, Gd, and Gt. The combined treatments of Sp, Sil, Gd, and Gt were administered orally for 12 months in doses of 20, 4, 0.8, and 6 mg/kg, respectively. Viral load, hematological parameters, liver, kidney functions, and blood glucose were determined in all HCV patients. The results confirmed that each treatment condition did no longer dispose of viral particles in HCV patients contrasted to patients treated with INF/Rib. Furthermore, in subject three, the treatment with Sp, Sil, Gd, and Gt caused a potential decrease in the viral load, progression of hematological pictures, decreased levels of liver enzymes (ALT, AST), and urea. In conclusion, these treatments could be used as adjunct to conventional treatment regimens.
