Magnesium (Mg) and its alloys are one of a novel kind of biodegradable metallic implants which attracted much fundamental research to develop its clinical application. Nevertheless, it has more restrictions in biomedical applications because it degrades too fast at the early stage after implantation, thus commonly leading to some problems such as early fast mechanical loss, hydric bubble aggregation, gap formation between the implants and the tissue. This work aims to study the effect of 0.5 wt% Sb addition on the microstructure, mechanical properties and degradation behavior of as cast Mg-4wt% Zn alloy. The evaluation process was conducted using optical and scanning electron microscopy, X-ray diffraction, tensile and compression tests, in addition to a corrosion study by immersing in simulated body fluid (SBF). Results showed that Sb refines the grain size of the base alloy and also enhances its mechanical properties and degradation rate as well. These were due to the formation of the secondary phase of Mg3Sb2. To get better degradation rate, the Mg-4wt% Zn and Mg-4wt% Zn-0.5wt% Sb alloys are coated with Ca-P using autocatalytic technique. The results demonstrated that the formed coat layer improves the degradation rate of samples under the condition of this study. The current study shows that Mg-4wt% Zn-0.5wt% Sb alloy has good mechanical properties and when it coated by Ca-P, it gave a better corrosion resistance that makes it ideal for biodegradable medical application.

The development of new and effective antitumor agents is one of the main goals of medicinal and biochemical research at present. The present study is concerned with the evaluation of the previously synthesized N-Butylpyridoquinoxaline 1,4-dioxide (NBPQD) as an antitumor agent against Ehrlich ascites carcinoma (EAC). The first part of the study (tumor imaging) was to investigate the biodistribution of NBPQD in the organs of EAC-bearing mice using iodine-125 isotope stressing on its distribution in the main organs (stomach, liver, spleen, kidney) in addition to blood and ascetic fluid. The second part was the assessment of the antitumor activity of NBPQD by estimating the tumor volume and the contents of total protein, total lipid, DNA and RNA in liver tissues. In addition, liver function tests and the redox status were assessed. Tumor volume and DNA, RNA, urea and malondialdehyde (MDA) levels and the liver enzymes activity were highly significantly increased (P < 0.001) in untreated EAC-bearing mice compared to control. However, total lipid and total protein in liver tissues in addition to serum albumin, glucose, reduced glutathione (GSH) as well as activities of glutathione reductase (GSH-R) and superoxide dismutase (SOD) all were highly significantly decreased in untreated EAC-bearing mice compared to controls. All these decreased parameters were highly significantly restored to their normal levels in NBPQD treated mice compared to the untreated EAC-bearing mice. The survival time of the NBPQD treated mice was longer than that of the untreated ones. It is thus, evident that NBPQD had a remarkable antitumor activity against EAC in Swiss albino mice.

Introduction: The purpose of cardiac rehabilitation is to improve the effects of aging and maintain a good quality of life for older individuals. This study aims to assess how cardiac rehabilitation affects the autonomy and quality of life of older adults. Patients and Method: This was a longitudinal, descriptive and comparative before-and-after cardiovascular rehabilitation study conducted over a two-year period from January 2019 to December 2021. This study was conducted at four cardiac rehabilitation units in Dakar: the Aristide Le Dantec Hospital (HALD), National Dalal Jamm Hospital, and the General Idrissa Pouye Hospital (HOGIP). We compared the degree of autonomy, dependence and quality of life of subjects aged over 65 before and after the cardiac rehabilitation program using the Katz index, the Lowton index and the SF12 quality-of-life questionnaire. Results: Over a two-year period, a total of 345 patients had benefited from a complete cardiovascular rehabilitation program in the four cardiovascular rehabilitation units in Dakar, and 86 patients, or 24.92% of the population, were at least 65 years old. The patients were predominantly male (sex ratio M/F = 4.73). The mean age was 70.35 ± 4.55 years for men and 69.27 ± 4.59 years for women. The main pathology motivating cardiac rehabilitation was ischemic heart disease, which was found in 73 patients (84.88%). Initial assessment revealed exertional dyspnea in 35 patients (40.69%), followed by residual exertional angina in 21 patients (4.41%). Mean functional capacity increased from 5.81 ± 2.38 Mets in pre-cardiac rehabilitation to 8.68 ± 2.28 Mets in post-cardiac rehabilitation (p < 0.001). The mean distance covered in the 6-minute walk test increased from 330.42 ± 170.50 m in pre-cardiac rehabilitation to 524 ± 98.54 m in post-cardiac rehabilitation (p = 0.119). The Lowton dependency index in pre-cardiac rehabilitation was 44.18% versus 36.04% in post-cardiac rehabilitation (p = 0.0156). The mental quality of
