Epidemiologic threats and outcome of evolving COVID-19-associated mucormycosis from a referral hospital in Egypt.

Introduction: The present study aimed to explore the epidemiologic threats and factors associated with the coronavirus disease 2019 (COVID-19)-associated mucormycosis (CAM) epidemic that emerged in Egypt during the second COVID-19 wave. The study also aimed to explore the diagnostic features and the role of surgical interventions of CAM on the outcome of the disease in a central referral hospital.

Methodology: The study included 64 CAM patients from a referral hospital for CAM and a similar number of matched controls from COVID-19 patients who did not develop CAM.

An eco-friendly and cost-effective approach for the synthesis of a novel GA@CuO-ZnO nanocomposite: characterization, antimicrobial and anticancer activities.

In this study, a nanocomposite based on copper oxide-zinc oxide nanoparticles and Gum Arabic (GA@CuO-ZnO nanocomposite) was successfully synthesized using green method. Characterization results revealed that the prepared nanocomposite appeared at the nanoscale level, showed excellent dispersion, and formed stable colloidal nano-solutions. The bimetallic GA@CuO-ZnO nanocomposite was evaluated for its anticancer, antibacterial, and antifungal properties.

Chemical characterization, neuroprotective effect, and evaluation of the petroleum ether extract of three palm tree species against glutamate-induced excitotoxicity in rats.

The burden of neurological disorders is growing substantially with limited therapeutic options, urging the consideration and assessment of alternative strategies. In this regard, we aimed to elucidate the phytochemical profile of the petroleum ether extract (PEE) of three palm tree species: Burret, H. Wendl.

Toxicity assessment following conventional radiation therapy and pulsed low dose rate radiation therapy: an in vivo animal study.

Background: Pulsed low dose rate radiotherapy (PLDR) is a new radiation delivery method, in which the fractional dose is divided into sub-fractional doses with periodical time breaks in between. The goal of our study is to assess the toxicity on healthy tissues resulting from PLDR as compared to conventional radiotherapy (CRT) using the same physical X-ray dose.

Methods: We analyzed the weight and survival time for CRT and PLDR groups and studied the inflammatory cytokine transforming Growth Factor-β (TGF-β), usually released following irradiation.
