Excessive exposure to lead may damage the liver by increasing oxidative stress, leading to many serious diseases. Dietary antioxidants may protect the liver from damage. Therefore, the effect of ethanolic and aqueous turmeric extracts against lead-induced liver damage was evaluated by estimating liver function and antioxidant/oxidative stress biomarkers. Forty rats were divided into group (A) served as the control and group (B) was treated with 93 mg/kg b.wt. lead nitrate; while group (C) and group (D) were treated as group B in addition to 400 mg/kg b.wt. of turmeric aqueous and ethanolic extracts, respectively. Group B showed a significant increase in the activities of alanine transaminase by 10 folds, aspartate transaminase by 9 folds, alkaline phosphatase by 3 folds and the level of malondialdehyde by 10 folds, while showed a significant decrease in albumin by 60%, total protein by 54.5%, and superoxide dismutase by 80.5%, catalase by 75% and glutathione by 71.6% in comparison with those of the control group. On the other hand, turmeric treatments (groups C and D) led to a readjustment of levels for such biomarkers. Collectively, these results demonstrate the potential of turmeric extracts (particularly the ethanolic extract) to improve the fatal effect of lead in a rat model.

In the sake of enhancing the thermal stability of α-Tocopheryl acetate (α-TA) and Strawberry Anthocyanins (AN), their encapsulation with starch or β-Cyclodextrin were prepared and characterized by UV-Vis and IR spectra in addition to thermal analysis. Thermal stability was investigated by comparing the thermographs of each host and guest with that of the prepared complex. Both hosts provided extra thermal stability to both guests where α-TA is stabilized from 230 to 291oC by complexation with starch and to 285oC by encapsulation with β-CD. AN was also stabilized from 40.02oC to 75.57 and 79.46oC by complexation with starch and β-CD respectively.

Aphids are considered one of the most economically important insect pests worldwide. Successful pest management systems are based on accurate and rapid pest species identification. Traditional morphological identification of closed aphid species may be considered an inaccurate taxonomic process. To overcome the disadvantages of traditional morphological identification, molecular techniques, related to DNA markers and based on polymerase chain reaction (PCR), were approached by using nine ISSRs primers to identify and diagnose fifteen common aphid species that disperse in the Egyptian agroecosystem. The examined ISSRs primers could success-fully discriminate the tested aphid species that reflected 61.39% polymorphism among them. Moreover, four banding patterns were considered unique bands that could characterize three aphid species (Aphis gossypii, Aphis nerii and Myzus persicae). The highest genetic homology (84.9%) was observed between species Rhopalosipum padi and Schizaphis graminum. In addition, each of A. gossypii and Aphis citricola were also genetically homologous species. In contrast, species Aphis craccivora and M. persicae were analogous genetically with a low similarity percentile (59.8%). High genetic di-vergence was observed also between A. nerii and M. persicae. Two alternative molecular branching taxonomic keys were proposed by subjecting the five highest polymorphic ISSRs primers and 29 banding patterns with different molecular sizes.

Laboratory experiments were carried out to clarify the impact of different types of natural and synthetic polymers on some hydrophysical properties (soil hydraulic parameters) of a sandy soil. Adding 0.5% (w/w) of each treatment to soil significantly increased water retention at saturation, field capacity, total available water and readily available water. This treatment decreased the value of inflection point on water retention curve as result of enhancing water behavior in the soil. The obtained results revealed that soil water storage significantly increased from 0.271 in control treatment (without adding polymer) up to 0.414 in treatment [T10] (Acrylic acid + Xanthan) while, field capacity increased significantly from 0.078 in control up to 0.242 of the abovementioned treatment (T10). Regarding the effects of polymer application in total available water and readily available water, data revealed significant increases in the above mentioned parameters. Total available water increased from 0.044 in control treatment up to 0.153 in T10 and readily available water increased from 0.057in control treatment up to 0.185 in T10. Concerning values of inflection point on soil water retention curve, the obtained results revealed that, inflection point of control treatment (1000 mbar) decreased to 590 mbar, as a result of adding a mixture of polymer acrylic acid + xanthan (T10 ).Soil depletion rate decreased as due to polymer application by 25% up to 75% depending on type of polymer and wether it was added individually or in combination with another polymer. This effect led to significant differences among control treatment (control) and the other treatments. Generally, there were significant effects of all polymers on the concerned hydrophyical properties of the studied sandy soil, i.e. storage capacity of soil water, depletion rate of soil water, soil field capacity , soil available water, readily available water and inflection point on the soil water retention curve. Acrylic acid recorded the best results concerning soil water behavior if it was added individually to the sandy soil (Treatment 2) or in combination with Xanthan (Treatment 10) or with Lignosulphonate (Treatment 11).

At the Experimental Farm, Agriculture Faculty, University of Ain Shams, Qaliobia Governorate, Egypt, in order to investigate the influence of biofertilizer ( Bio. ); Rhizobium ( R ), mycorrhiza ( MF ), R + MF and control, seaweed extract (SWE) concentration (zero, one, two and four gram per liter) and their interactions on vegetative growth, productivity and quality of seed common bean cv. Nebraska. Before planting, the seeds were soaked in MF (glomus sp.) and sown on the first of March 2016 and 2017 seasons respectively. The experimental plot area was seven m2 (four rows). The length of each row was 2.5 m and width of 0.7 m. The plant's distance was seven cm on one side, and an alley (one width m) was left as a border between the treatments. After two weeks of planting, young plant were inoculated with R phaseolus after the first irrigation. Plants were sprayed three times of SWE (30, 45 and 60 days) after sowing. A split plot design with four replicates was used; where the main plots are Bio treatments and the subplots are SWE treatments. The obtained results clearly indicated that different applied treatments increased measured growth characteristics (No. leaves/ plant, leaf area and total chlorophyll (SPDS)), the yield and components of yield (No. pods/plant, seed yield /plant and seed yield) and chemical constituents (total protein, carbohydrates, nitrogen and phosphorus) in seed after harvest. As well as, the best results were obtained by interactions between SWE (two and four gram per liter) and Bio. (R + MF) treatments in the two assigned seasons So adding combination between Bio. ( R + MF ) and SWE (two or four g) to improve vegetative growth, productivity and quality of common bean seed could be recommended under organic system ( conversion to organic agriculture ).

This study was carried out in a private farm in Wardan, Giza governorate in Egypt during 2019 season on strawberry plants. The first experiment aimed to evaluate the effectiveness of different commercial products in cultivated land including Solo 24% SC (Bifenazate), Arbus 12% SC (Chlorfenapyr + Emamectin benzoate) , Concor 24% SC (Spirodiclofen), Excellent 1.9% EC (Emamectin benzoate) , Top9 (Chitosan 0.1%) , Biomectin 5% EC (Abamectin) and Congest 15% CS (Abamectin + Imidacloprid) in reducing the population densities of two spotted spider mite, Tetranychus uriticae Koch. on strawberry plants. According to general mean percentage of reduction in population of T. uriticae, data showed insignificant differences among the seven tested compounds whereas the mortality percentages were 85.94 %, 82.18%, 81.4%, 79.36%, 78.14%, 77.94% and 75.9%, respectively. From these results; it’s clear that Solo compound is the most effective compound and Congest is the lowest one. The other compounds ranged between them in controlling T. uriticae under these experimental conditions. The second experiment evaluated the effectiveness of different formulations in the nursery including Radiant (Spinetoram 12% Sc), Super Rigo (Naphthyl acetic acid – Chitosan), Top9 and Berna Star (Glyceryl stearate 32%) in reducing the population densities of western flower thrips, Frankliniella occidentalis (Pergande) on strawberry plants. According to general mean percentage of reduction in population of F. occidentalis, data showed significant differences among the four compounds. These compounds could be divided into three groups. The first group contained Radiant compound showing high mortality (63.5%). The second group contained Super Rigo and Top9 compounds showing moderate effect (46.44% & 34.3%), respectively. The third group contained Berna Star compound showing least effect (28.36%). From these results; it’s clear that the chemical compound Radiant is the most effective while the natural compound Berna Star is the lowest in controlling F. occidentalis under these experimental conditions.

This study aims to use solar energy to warm poultry houses instead of traditional energies which have shortage and high cost of using. The prototype was designed and Fabricated at workshop of agriculture engineering research institute (AEnRI) - ARC and the experiments were conducted at Solar Energy Laboratory - Agricultural Engineering Department Faculty of Agriculture - Ain Shams University (Latitude 30° 02′ N, Longitude 31° 21′ E).

Nanoparticles (NPs), especially from micronutrients, are recently motivated for replacing their common mineral counterparts. To evaluate their comparative efficacy, this investigation was conducted to estimate the impact of foliar application of zinc through different sources on productivity, fruit quality and improve marketable fruit of “Wonderful” pomegranate trees. The field experiment was performed during two seasons (2017 and 2018) on seven - year old pomegranate trees “Wonderful” cv., cultivated in a private “Hegazi” farm located at 57 km. from Cairo on the road to Alex., Egypt. Four sources of zinc named “Zinc Sulphate, Zinc mannitol complex, Bio-Nano zinc (Bio Zn NPs) and Zinc Oxide nanoparticle (ZnO NPs) with four rates from each other were sprayed twice (the first before one week from full bloom and the second after a month from the first). So the experiment included seventeen treatments in a sample study spread in a randomized complete block design by five replicates. Results explicated that the greatest significant values of fruit set% were recorded by Bio Nano Zinc (Bio Zn NPs) treatments especially (400 ppm Bio-Nano Zinc (Bio Zn NPs)). Spraying with (3000, 4000 ppm Zn mannitol complex) and (300, 400 ppm Bio-Nano Zinc (Bio Zn NPs)) showed significantly the greatest values of productivity, improves marketable fruits and fruit quality of “Wonderful” pomegranate trees. So it could be recommended by spraying “Wonderful” pomegranate trees by 3000 ppm Zinc mannitol complex or 300 ppm Bio-Nano zinc (Bio Zn NPs). Another important point is that the application of Bio Zn NPs fertilizer at around 10% from the commercial dose of zinc sulphate resulted in the same results without any change in the productivity, further researches are needed to study a further low level of Zinc Oxide nanoparticle (ZnO NPs) below (100 ppm Zinc Oxide nanoparticle (ZnO NPs)) which may be improving yield and fruit quality

The effect of Pink Pigmented Facultative Methylotrophic (PPFM) bacteria as a bio-stimulant on vegetative growth, macro-nutrient elements ( N,P and K ) contents , chemical constituents and volatile oil percentage and components in rosemary plant (Rosmarinus officinalis L.) were studied during 2018 and 2019 seasons. Plant height (cm), number of lateral branches/plant, herb fresh & dry weights and root fresh & dry weights of rosemary plant were all greatly affected with all applied treatments of PPFM when compared with the control. The hugest effect was recorded by 1% PPFM bacteria spraying in both studied seasons. However, no significant effect was recorded due to PPFM applied treatments on P%. Highest values of total carbohydrates were recorded by both 1 and 3%. PPFM bacteria spraying in both studied seasons. Whereas, the highest values of C/N ratios were obtained with 3% PPFM in first season and 1% PPFM in the second one. A substantial effect from PPFM bacteria spraying was observed through its effect on reducing the level of NO3 and NO2 in rosemary herb when compared with the control. In any case, 3% of PPFM bacteria spraying was more effective than other treatments in recording the least values of NO3 and NO2 in first season compared to the control. Volatile oil % was enormously increased with 3% PPFM bacteria spraying in both studied seasons than other treatments or control. The main components of volatile oil of rosemary plant were Camphor, Eucalyptol, Verbenone, Borneol, Pinene, Pinanone, Bornyl acetate and Camphene. The treatments of PPFM bacteria spraying immensely stimulated the component % in volatile oil of rosemary herb than in the control. It could be concluded that the application of PPFM bacteria as foliar spraying in rosemary plant production had many advantages especially reducing NO3 and NO2 levels and increasing volatile oil % and volatile oil fractions not to mention it increased the percent of active ingredients.

The present study aimed to produce function yoghurt drink fortified with different types of herbal extracts (Ginger, Amla, Curcuma) and assess its therapeutic effect in hepatitis rats. The rats were randomly divided into two main groups. The first group were control (-) (6 rats) was fed on a standard diet, while the second group (30 rats) were fed on standard diet and injected it by CCl4 "for two weeks" to induce chronic damage in the liver (hepatitis) then divided into five groups (6 rats each group), then treated by plain drinking yoghurt and different herbal drinking yoghurt fortified with different types of herbs extract. Different Biological attributes were determined. The antioxidant activity, total phenolic content and chemical properties were evaluated in herbal extracts and yoghurt product and their hepatoprotective effect of each alone evaluated in albino rats against carbon tetrachloride (CCL4) induced liver injury. The hepatoprotective activity was assessed using various biochemical parameters and histopathological studies. The results indicated that functional flavoured drinking yoghurt containing herbal extract exhibited no significant differences were observed in total solids, fat, protein, ash, and lactose content them control samples. Drinking yoghurt fortified with Curcuma exhibited highest content of antioxidant activity and total phenolic content among all treatments. Also, rats fed on diet supplemented with drinking yoghurt fortified with Curcuma for 28 days showed higher potential hepatoprotective effects compared to liver injury control group (IC). The rats succeeded to restore the biochemical parameters and improved the histological alteration of the liver. This improvement was pronounced partly in the group received drinking yoghurt fortified with Ginger and Amla herbal extracts while, the group received drinking yoghurt fortified with Curcuma herbal extract were improved totally. It could be concluded that drinking yoghurt fortified with different herbal extract especially Curcuma can be used as ingredients in functional foods for people suffering from liver diseases.
