In this study, we prepared a fine-grained, aluminum-reinforced alumina support matrix of the active mass of catalysts, which showed activity in heterogeneous catalytic reactions stimulated by electromagnetic radiation in the microwave range. The support absorbed microwave radiation of 2.45 GHz. We compared the textural characteristics of samples of Al/Al2O3 supports obtained by conventional heat treatment to those synthesized by heat treatment in a microwave field. We found several advantages of heat treating poten [...]

Diseases of the liver are commonly encountered in patients with Inflammatory Bowel Disease (IBD). While the differential for IBD patients with elevated liver associated enzymes is broad, it is similar to that of the general population. This differential includes including non-alcoholic fatty liver disease (NAFLD), the most common liver disease in North America. When initial work-up for elevated liver associated enzymes is negative and patients have steatosis on ultrasound, we counsel IBD patients aggressively about [...]

The COVID-19 pandemic brought different intolerable and uncomfortable situations that ruined the students' academic performance, career opportunities, and social lives through depression, anxiety, fear, uncertainty, and mental illness. In this study, we examined the psychological threats of the COVID-19 among Egypt’s public-sector university students. We employed quantitative methods in this study and used a questionnaire to collect cross-sectional data. The Structural Equation Modeling (SEM) results show that Fear [...]

There has been a steady expansion in islet isolation and transplantation activity worldwide. In addition to preparing human islets for transplantation, we have been providing human islets to basic researchers. The aim of this study was to review the activity of distribution of human islets to basic researchers in North America, Europe, and Asia, and to investigate if there are any differences in utilization rate of islets among three continents. We reviewed our islet isolation batch files, donor records, and docume [...]

One major cause of aquatic pollution is the accumulation of heavy metal ions. This study shows the biosorption properties of orange peel for removing chromium (CrVI) from industrial wastewater at a laboratory scale. This study focused on the biosorption of CrVI using orange peel biosorbent (OPB) from aqueous solutions in the plastic industry (PI), textile and fabrics industry (TFI), chemical industry (CI), and food industry (FI). The total Cr contents in effluents of FI, CI, TFI and PI varied between 30.0-38.0, 23. [...]

Liver transplantation has steadily increased worldwide resulting in a large number of patients on the waiting list. Due to the opioid epidemic in the US, the pool of Hepatitis C seropositive donors increased significantly in recent years. Direct acting antivirals played an instrumental role in making liver transplantation with hepatitis C positive allograft an acceptable option. Although hepatitis C positive liver transplantation to hepatitis C positive recipients is a common practice, there is limited data and agr [...]

While it may seem intuitive to suggest that compassion aids in the healing process, there is actual evidence to support that compassion changes physiology, which in turns affects emotional and physical healing. The focus of this opinion paper is on the use of compassion between health care providers and patients based on the use of compassion in the mental health field. Not only do patients benefit from compassion, but health care providers may also benefit. Creating compassionate relationships with patients may [...]

In this study, the researchers explore the effects of COVID-19-related challenges, such as fear and anxiety about COVID-19, the uncertainty of COVID-19, and the recognition of business opportunities for entrepreneurial intentions and business startups. This study used quantitative methods and based their findings on 278 usable samples collected from Egyptian entrepreneurs. Employing the Structural Equation Model (SEM) through SmartPLS4 shows that fear and anxiety arising from the COVID-19 pandemic harm entrepreneur [...]

Carbon capture and storage (CCS) technology mitigates greenhouse gas (GHG) emissions. However, comprehensive studies assessing the sustainability of coal-based power generation (CBPG) with CCS remain limited. This study focuses on developing comparative sustainability indicators across the entire life cycle of CBPG integrated with CCS technology. Sixty-six pathways were analyzed after establishing five sustainability indicators for each. These indicators were standardized per megawatt-hour (MWh) of energy, encompas [...]
