Worldwide, high mortality rates are caused by the terrible disease of cancer. By causing harm to lipids, proteins, and DNA, reactive oxygen species cause disease. A malignant transformation is brought on by increased quantities of reactive oxygen species, which are boosted by down-regulation of cellular antioxidant enzymes. A well-known flour enhancer is potassium bromate, a chemical oxidizing agent. When administered for an extended period of time, it can damage cellular structures and target cellular constituents through reactive oxygen species, which increases the risk of cancer. Silymarin is one plant polyphenol that has been found to be a safe treatment for cancer and other disorders. Silymarin\'s antioxidant properties, antiproliferative activity, and cell cycle arrest, which causes apoptosis in cancer cells, are the basis of its anticancer mechanism of action. This study looked at the effects of silymarin and potassium bromate on mice that had Ehrlich ascites carcinoma cells. The liver and kidney were subjected to histopathological and immunohistochemical examinations, and the cells from Ehrlich ascites carcinoma were subjected to an ultrastructural investigation. In the liver and kidney of Ehrlich ascites carcinoma-bearing mice, silymarin was found to eradicate tumors and improve the histological abnormalities brought on by Ehrlich ascites carcinoma cells. Potassium bromate caused mitochondrial degeneration and nuclear distortion in Ehrlich ascites carcinoma cells and improved the histological changes. According to the results of the current investigation, potassium bromate and silymarin have the potential to be effective anticancer treatments. However, further toxicological studies are required to substantiate their mammalian safety and to determine the relevant therapeutic doses.
We were interested in the effect of a xenobiotic, methyl parathion (organophosphorus pesticide used to control some environmental pests), on particular organs of broilers in our experimental investigation. For this objective, several dosages of TPM (lower than the LD50) were administered to chicks through gavage from day 8 to day 70ème of development. This liposoluble xenobiotic was diluted in olive oil, and four batches (n=15 each) were created, which are: witness, witness to which olive oil is added, treated at a dose of 0.1, and another at 0.3 g/kg of fresh weight. We attempted to calculate the effects of this pesticide on two target organs: the liver and the kidney. The histological results sections indicated structural changes in the liver and kidney. These results clearly show that TPM is very harmful to birds and should be examined in terms of its influence on ecosystems, biodiversity, and wild bird population, as well as human health.
Lightning always enchants mankind with its brightness and power. Even this phenomenon is present in the human being’s life it is not totally understood. This event occurs due to electric charge of opposite polarity, where positive and negative charge in cloud regions can develop high voltage between them, between one charged region and ground, causing electric discharge. In this paper, the lightning path, assuming its cloud-to-ground downward negatively charged leader, is analyzed theoretically considering the erratic trajectory of electrons from diffusion approach with its perpendicular and parallel coefficients, considering two (2D) and three-dimensional (3D) random walk approaches. Algorithms are offered, whose results for electrons displacement are presented as 2D and 3D-cartograms, showing the erratic leader lightning path cloud-to-ground downward.
A novel ZnO nanostrctures has been synthesized by a sol-gel method based on network of NH3•H2O. The obtained results showed the synthesized nanostrctures at best conditions has excellent linear nanorod created from nanograins. Each nanograin was made of nanoparticles ZnO. Temperature sensors are a type of resistor whose resistance varies significantly with temperature. Different ZnO Nanostructures such as nanorods, nanoparticles and nanobelts have been grown and used for preparation temperatures sensors. Because of more surface contact of ZnO nanorods, more gas molecules are adsorbed on the ZnO nanorods surface. Sensitivity of different type of sensors has been investigated by energetic O2 gas with studying of ZnO Nanostructures morphology. ZnO Nanostructures were synthesized by zinc nitrate, ammonia as the starting materials at a low temperature. The effects of the concentration of ammonia, the influence of pH value, temperature and time on the morphologies of ZnO have been investigated. The ZnO with ph 10.5 has a homogeneous and dense surface with grain size about 30 nm. \nThe obtained results indicate that something like ad-atoms and rest-atoms of ZnO, change the morphology and sample surfaces. Characterizations were carried out by X-Ray Diffraction (XRD), Atomic Force Microscopy (AFM), Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM) techniques.

The present study aims to basically collect descriptive information using Delphi survey method to investigate the availability or lack of relationship among major hypotheses that include some minor hypotheses as well. The majors assess the relationship between organizational learning and empowerment of human resources. In this study Kolmogorov-Smirnov, and t-Students, Friedman’s rating test and factor analysis of partial least squares (PLS) used to test the research hypotheses. The results are going to determine the impact of each intrinsic variable (dependent) and extrinsic (independent) on increasing empowerment of human resources. According to present conditions and provided impact factors, investigators can choose the path leading to development and empowerment of human resources.
Climate change is among the topmost economic development challenges in sub-Saharan Africa (SSA). This paper analysed the effect of rural households’ adaptation options on monthly food shortages. The data were collected with multi-stage sampling by the Climate Change, Agriculture and Food Security (CCAFS) as a baseline survey to provide comparable data on the impact of climate change in Burkina Faso, Ghana, Mali, Niger and Senegal using multi-stage sampling method. Data were analyzed with descriptive statistics and Poisson regression model. Results show that reported erratic and less overall rainfalls mostly affected peanut, although in Burkina Faso and Mali, sorghum and millet were most affected. The farmers were making some changes on their farming systems with 15.94 percent introducing new crops in Senegal, 23.57 percent tested new crops in Niger and 81.43 percent grew high yielding varieties in Ghana. Drought resistant varieties were grown by 20.71 percent of the farmers from Burkina Faso, 17.86 percent of those from Ghana and 12.06 percent of those from Mali. The results of Poisson regression revealed that the data were adequately fitted judging from statistical insignificance of the deviance goodness of fit (p>0.10). Specifically, more involvement of men in raw food production, late planting of crops, number of months households depended on home production, residence in Mali and Senegal reduced the count of monthly food shortages, while introduction of stone lines, residence in Ghana and more involvement of men in timber production increased it (p<0.05). It was concluded that adequate adaptation will assist farmers to mitigate the impact of climate change on food security.
The study revealed the nature of the state change information system of the liver tissue with gepatadenome, liver cancer and non-cancer pathologies. Was shown that information parameters of non-cancer diseases indicate that liver tissue system uses existing structural adaptation resources. Information system of tumors of the liver is simplified and streamlined. Changes of information parameters characterizing a liver indicate various kinds of adaptive processes in the tissue at various pathologies.
