Authors: Hasan Bushra A , Uamran Duaa A 
Published: July 2019

AbstractBulk AlxSb1-x samples were prepared with different x ratios (0.1, 0.3, 0.5, 0.7 and 0.9) by quenching technique. This was done throughout mixing the aluminum and antimony elements according to the proper atomic weight and put them in an evacuated quartz ampoule which then sealed and heated at 1273 K for five hours and left to cool in air. Thin films of AlxSb1-xwere prepared by using thermal evaporation under vacuum of 10-5 mbar on glass substrates at room temperature with deposition rate (10-15nm/min) at thickness of ∼ 500nm. The structures of AlxSb1-x bulk and thin films have been studied by X–ray diffraction technique. The results showed that all alloys have polycrystalline structures and the peaks at composition ratio x = 0.3, 0.5 and 0.7 were identical with the AlSb standard peaks while at x = 0.1 and 0.9 the peaks are identical with Sb and Al respectively. The x-ray pattern of the prepared thin films are polycrystalline and the peaks identical with cubic structure also the peaks intensity decrease with the increase of aluminum ratio in the prepared thin films. AFM measurements showed the non-regular variation (increasing and decreasing) of both the average grain size and average surface roughness with the increasing of composition ratio. AlxSb1-x thin films showed high charge carrier concentration nHespecially at x = 0.1 and 0.3 on the other side charge carrier concentration showed reduction with the increase of aluminum content whereas nHreach minimum value at x = 0.7 and then increases with further increase of aluminum content. The electrical conductivity of AlxSb1-x declare similar behavior where it reach minimum value at x = 0.5. From another side AlxSb1-x thin films show high conductivity resemble that of metallic material especially also at x = 0.1 and 0.3.

Published: July 2019

Abstract
For measuring the nonlinear refraction index n2 and absorption index β, we have used modified Z-scan technique with the single laser beam. The media is a nanocomposite films made from the binary (Bi2S3 and Bi2Te3) with PMMA. The material is prepared via the microwave-assisted chemical method. The Characterization of the nanocomposite films was carried out using X-ray diffraction (XRD), and U-V spectroscopy. The band gaps of Bi2S3 and Bi2Te3 are 2.6ev and 2.38ev respectively. XRD shows that Bi2S3 and Bi2Te3 have orthorhombic and trigonal (hexagonal axes) structures respectively. The optical non-linearity is intensity dependent. The nanocomposite films exhibit self-defocusing nonlinearity beneath the empirical conditions. Both samples exhibit a large negative nonlinear refractive index and good nonlinear absorption coefficient with increasing laser input power. The spotted nonlinear refraction and absorption are related to thermal in nature and reverse Saturable absorption, respectively. The obtained results indicate that the nanocomposite films may open several new possibilities of using these materials in all-optical element devices.

Published: July 2019

Abstract
Breast cancer (BC) is the primary cause of women cancer death, which could be prevented by EGCG that has been recently shown several health properties included anti-cancer, however the mechanism underpinning still poorly understood. In this study, several biological activities of both MCF7 and MDA-MB-231 cells were evaluated in response to EGCG. Cell viability and the role of Akt and AMPK inhibitor molecules, and sodium pyruvate on this viability, apoptosis, metastasis, and interestingly regulation of glucose metabolism were assessed. EGCG promoted cytotoxicity in both BC cell lines after 24h but not less. Co-incubated cells with Akt and AMPK inhibitors alongside EGCG significantly caused more reduction in cell viability compared to the effect of EGCG alone with maximum effect referred to Akt inhibitor. While supplemented sodium pyruvate significantly restored the decreases in cell viability. Remarkably, EGCG induced apoptosis through increased caspase 3/7 activation associated with upregulated Bax gene, in addition to anti-metastatic effect through decreasing cellular migration. Importantly, lactate production was sharply reduced after 6h (no alteration of viable cells) and 24h (decreased viable cells) concomitant with significant blocked glucose uptake in response to EGCG. In conclusion, EGCG could be a potential anti-migration, the anti-cancerous therapeutic agent through targeting cancer cells glucose metabolism.

Abstract
Smoking is the most spreadable habit between people on earth surface impacting human body functions and causing health risks. Our study aimed to estimate cadmium, lead, and iron concentrations in the blood of hookah (Shisha) smokers compared to non-smokers. This project was conducted over a period of time between October (2017) to February (2018) in Najaf province. This period was used to determine smoking hookah effects on heavy elements depositions in blood and organs of smoker’s compared to non-smokers. Forty samples of men were measured as a total, divided into 30 samples of smokers and 10 non-smokers. Cadmium, lead, and iron levels were measured in each individual serum. Kidney functions; blood urea, creatinine, and glucose were also examined. Liver functions tests including ALT (Alanine aminotransferase) and AST (Aspartate aminotransferase) were also investigated.
Our results exhibit a significant increase in blood platelets and white blood cell values in smokers while a trend of increasing in hemoglobin values in smokers compared to non-smokers were found not significant. A decreasing in red blood cells of smokers compared with non-smokers was also found non-significant. A significant increase of liver functions in blood of smokers compared to non-smokers were found. Only glucose was significant in smoker’s kidney function. There was a marginal significant differences of cadmium in smoker’s blood compared to non-smokers. Our study concluded there were a trend of high levels of heavy metals in smokers with high variations in our results. These variations could be related to other factors. More studies focusing on the relationship between organs’ functions (e.g. lung) and heavy metals could support our findings by elucidating smoking consequences. Also, considering age, sex, diet, and inheritable status need to be considered in further studies.
