Optimization using central composite design for continuous absorption of CO gas with green sodium silicate in a packed bed column.

If absolutely nothing is taken to reduce carbon dioxide (CO) emissions, atmospheric concentrations of carbon dioxide will rise to 550 parts per million by 2050, which will have disastrous effects on the world's climate and food production. An apparatus has been designed and setup to convert CO into a useful and vital product which was silica. The effect of different experimental factors on the compositions by weight percent of SiO and NaCO were studied including the CO gas flow rate (1.

Impact of Sarcopenia on Short-Term Complications and Survival After Liver Transplant.

Objectives: Sarcopenia is a common entity in cirrhosis with significant morbidity and mortality. However,the effects of sarcopenia on the risk of complications and survival after liver transplant remain controversial.We aimed to evaluate the effect of sarcopenia on survival and complications after liver transplant.

Measurement of Power Frequency Current including Low- and High-Order Harmonics Using a Rogowski Coil.

The measurement of a power frequency current including low- and high-order harmonics is of great importance in calibration as well as in testing processes. Therefore, this paper presents the measurement of the power frequency current of light-emitting diode (LED) luminaires. LED luminaires were chosen as their input current includes both low- and high-order harmonics.

The Impact of Comorbidities on the Outcomes of Egyptian COVID-19 Patients: A Follow-Up Study.

Objectives: This study evaluated the clinical manifestation of COVID-19 and adverse outcomes in patients with comorbidities (outcome: death).

Methods: A comparative follow-up investigation involving 148 confirmed cases of COVID-19 was performed for a month (between April and May 2020) at Qaha Hospital to describe the clinical characteristics and outcomes resulting from comorbidities. Participants were divided into two clusters based on the presence of comorbidities.

Ledipasvir/Sofosbuvir in Adolescents With Chronic Hepatitis C Genotype 4 With and Without Hematological Disorders: Virological Efficacy and Impact on Liver Stiffness.

Background: Egypt has the highest prevalence of hepatitis C virus (HCV) infection. Anti-HCV antibodies were detectable in 3% of children in Upper Egypt. Our aim was to evaluate the efficacy of ledipasvir/sofosbuvir for chronic HCV genotype 4 in adolescents with/without hematological disorders and to determine the effect of sustained virological response (SVR) on liver stiffness.

Role of Bone Marrow Derived Mesenchymal Stem Cells and the Protective Effect of Silymarin in Cisplatin-Induced Acute Renal Failure in Rats.

Background: Cisplatin is a highly effective antitumor agent whose clinical application is limited by its nephrotoxicity, which is associated with high mortality and morbidity rates. We aimed to study the protective role of silymarin and mesenchymal stem cells as a therapeutic tool of cisplatin nephrotoxicity.

Materials And Methods: We injected rats with cisplatin in a dose of 5mg/kg body weight for 5 days to induce acute renal failure (ARF).

Health in times of uncertainty in the eastern Mediterranean region, 1990-2013: a systematic analysis for the Global Burden of Disease Study 2013.

Background: The eastern Mediterranean region is comprised of 22 countries: Afghanistan, Bahrain, Djibouti, Egypt, Iran, Iraq, Jordan, Kuwait, Lebanon, Libya, Morocco, Oman, Pakistan, Palestine, Qatar, Saudi Arabia, Somalia, Sudan, Syria, Tunisia, the United Arab Emirates, and Yemen. Since our Global Burden of Disease Study 2010 (GBD 2010), the region has faced unrest as a result of revolutions, wars, and the so-called Arab uprisings. The objective of this study was to present the burden of diseases, injuries, and risk factors in the eastern Mediterranean region as of 2013.

Which statin worked best to achieve lipid level targets in a European registry? A post-hoc analysis of the EUROASPIRE III for coronary heart disease patients.

Objective: The objective of the study is to determine the proportion of patients within the subsample reaching the target lipid levels defined in the European guidelines, stratified according to type and dose of statin used.

Background: Many factors affect the attainment of lipid level targets including gender, age, compliance, statin type, and dosage. This study aimed to determine the percentage of post-interventional coronary heart disease (CHD) patients who met the lipid level targets recommended by the Joint European Societies Guidelines, the medications used, and their doses.
