This study designed to evaluate the deleterious effects of iron overloaded on organs weights , enzyme activity of liver and bilirubin, iron concentration, total iron binding capacity in serum and on bone marrow cells proliferation in mice.
The obtained results showed non significant differences in organ weights (spleen and kidney) in group 1 that treated with three parts extracts of pomegranate except the decreasing in spleen weight subgroup 1-4 , significant increasing in liver and kidney weight in all animals treated with iron dextran (group 2) in comparison with their weights of organs in negative control (group 1). While significant increasing in iron concentrations in serum of animal administrated peel and juice in comparison with their positive control, furthermore , a significant increasing in its concentration extract in serum of animal that induced iron overload. Furthermore the increasing were significant in TIBC in serum of group 2 and that level were reduced to 83.1 % ,33% and 67.1% in serum of mice post treated with seed, peel and juice respectively , and the level of TIBC were at its lowest recorded in serum of group 1, while the highest TS% were recorded in group 1 ,in contrast group 2 that revealed lower TS% especially in animal administrated iron dextran only.
The study also showed significant increases in the level of AST and ALP activity and bilirubin in serum of almost all animals administrated by the three typesof pomegranate extracts,but the results also illustrated that the extracts could be reduced the highest levels of AST, ALP and bilirubin in serum of the animals with iron overload when administrated post treatment.
On the other hand, the results illustrated that the juice extract induced significantly bone marrow cells proliferation in group 1 and the animals administrated iron dextran, while the administrated animals with peel and seed extracts in group 2 reduced their bone marrow cells proliferation significantly in comparison with the positive control. Non significant differences were recorded in total chromosomal aberration in bone marrow cells in group 1, while the CAs revealed significant differences in group 2 especially in animals administrated iron dextran and the type of aberrations represented was mainly of chromatid break, dicentric, a centric chromosome and ring chromosome.

Chromium oxide (Cr2O3) doped ZnO nanoparticles were prepared by pulsed laser deposition (PLD) technique at different concentration ratios (0, 3, 5, 7 and 9 wt %) of ZnO on glass substrate. The effects of ZnO dopant on the average crystallite size of the synthesized nanoparticles was examined By X-ray diffraction. The morphological features were detected using atomic force microscopy (AFM). The optical band gap value was observed to range between 2.78 to 2.50 eV by UV-Vis absorption spectroscopy, with longer wavelength shifted in comparison with that of the bulk Cr2O3 (~3eV). Gas sensitivity, response, and recovery times of the sensor in the presence of NH3

Samples of the root nodules were collected to isolate different species of the genus Rhizobium from several leguminous plants; Trigonella foenum-graecum, Medicago sativa, Lens culinaris, Vigna mungo, Vicia faba, Phaseolus vulgaris, and Cicer arietinum, and based on their morphological, cultural, and biochemical characteristics, in addition to the identification of each isolate at the species level by amplified polymerase chain reaction (PCR) and using the sequencing of the nitrogenous bases of the 16S rRNA gene, it was identified as Sinrhizobium meliloti, Sinrhizobium meliloti, Bradyrhizobium elkanii, Rhizobium leguminosarium biovar viciae, Rhizobium leguminosarium biovar phaseoli and Mesorh

In this work, metal oxide nanostructures, mainly copper oxide (CuO), nickel oxide (NiO), titanium dioxide (TiO2), and multilayer structure, were synthesized by the DC reactive magnetron sputtering technique. The effect of deposition time on the spectroscopic characteristics, as well as on the nanoparticle size, was determined. A long deposition time allows more metal atoms sputtered from the target to bond to oxygen atoms and form CuO, NiO, or TiO2 molecules deposited as thin films on glass substrates. The structural characteristics of the final samples showed high structural purity as no other compounds than CuO, NiO, and TiO2 were found in the final samples. Also, the prepared multilayer structures did not show new compounds other than th
