Introduction: The improvement of survival in patients with cancer and the expansion of therapeutic options have led to the emergence of a new profile of cardiotoxicity, specifically associated with antimitotic agents. Our study aimed to assess the incidence of chemotherapy-induced myocardial toxicity in patients with cancer. Patients and Methods: We conducted a looking-forward longitudinal cohort study including all patients admitted to the Cardiology departments of Aristide le Dantec hospital and Dalal Jamm National hospital Centre for apre-chemotherapy check-up. The included patients did not undergo any pre-existing cardiopathy. Results: Over a period of two years ranging from January 2019 to December 2021, a total of 37 patients were included in the study. Notably, there was a female predominance (92%) with an average age of 49.7 years ± 13.69. Breast cancer accounted for 70% of the neoplasms. Laboratory findings revealed moderate anemia in 19 patients (51%). At inclusion, the left ventricle (LV) was of normal size (LV diastole at 44.46 ± 4.97 mm). The systolic function of the left ventricle was normal in all patients, with an average ejection fraction (EF) of 63.1% ± 5.80 and a mean global longitudinal strain (GLS) of −20.4% ± 2.58. The most commonly used agents were anthracyclines. During follow-up, 3 patients (8.1%) developed clinical symptoms of left heart failure, and LV dysfunction on echocardiography was observed in 5 (13.5%) patients, with a significant decrease in EF Conclusion: The incidence of cardiac toxicity is not negligible, hence the importance of early screening. Strain imaging is an essential tool that should be performed as part of the assessment before chemotherapy and re-evaluated during treatment.

We investigate the spectral response of nanostructured copper oxides thin film. Gold was doped in two different concentrations(2% and 4%) using the spray method. A novel ammonia gas sensor at various concentrations(0–500 ppm)was fabricated by replacing CuO films with a clad region. In addition, the effect of gold doping on structural, optical,and morphological properties has been demonstrated. The study shows that the spectral intensity increases linearly with ammonia concentration. The 4% Au doped CuO presents higher sensitivity compared with 2% doped and pure copper oxides. Time response characteristics of the sensor are also reported.

The present study establishes a new estimation model using an artificial neural network (ANN) to predict the mechanical properties of the AISI 1035 alloy. The experiments were designed based on the L16 orthogonal array of the Taguchi method. A proposed numerical model for predicting the correlation of mechanical properties was supplemented with experimental data. The quenching process was conducted using a cooling medium called “nanofluids”. Nanoparticles were dissolved in a liquid phase at various concentrations (0.5， 1， 2.5， and 5% vf) to prepare the nanofluids. Experimental investigations were done to assess the impact of temperature， base fluid， volume fraction， and soaking time on the mechanical properties. The outcomes showed that all conditions led to a noticeable improvement in the alloy’s hardness which reached 100%， the grain size was refined about 80%， and unwanted residual stresses were removed from 50 to 150 MPa. Adding 5% of CuO nanoparticles to oil led to the best grain size refinement， while adding 2.5% of Al2O3nanoparticles to engine oil resulted in the greatest compressive residual stress. The experimental variables were used as the input data for the established numerical ANN model， and the mechanical properties were the output. Upwards of 99% of the training network’s correlations seemed to be positive. The estimated result， nevertheless， matched the experimental dataset exactly. Thus， the ANN model is an effective tool for reflecting the effects of quenching conditions on the mechanical properties of AISI 1035.

The development of rural areas usually has a positive impact on the urban-rural integration. This study explores an innovative approach to stimulate rural development by proposing qualified villages as central villages that can provide basic urban services for their residents and residents of neighboring villages. This approach can contribute to overcoming the various problems that rural areas faced at the social, economic, and environmental levels. It seeks to achieve spatial sustainability of rural areas, representing a new approach by integrating urban development methods to revitalize rural villages. The study analyzed 15 villages belonging to Abbasiya District of AL Kufa City in the Najaf Governorate of Iraq. Based on the GIS techniques and the analysis of urban service indicators(village population, percentage of urban building materials used in villages, distance between village and health centers, distance between village and main roads, nature of economic activity, distance between village and educational institutions, distance between village and drinking water sources, number of communication towers, and distance between village and urban administrative center), this study proposed that Abu Gharb and Albu Ghraib can served as central villages in Abbasiya District in the future. This study establishes a new rural spatial structure to achieve rural sustainable development, improves the development status of rural areas, and provides a theoretical basis for the government and relevant institutions to use urban service indicators, achieving rural sustainable development and formulating relevant development policies in Abbasiya District.
