This study investigated the green synthesis of Zn-MnO nanocomposites via the fungus Penicillium rubens. Herein, the synthesized Zn-MnO nanocomposites were confirmed by UV-spectrophotometry with a top peak (370 nm). Transmission electron microscopy confirmed irregular particles with a spherical-like shape ranging from 25.

Coconut oil is eatable oil with many nutritional and cosmetic applications. In this investigation coconut oil was subjected to 0 to 5 L/min of ozone for 3 h and the chemical composition of both crude and ozonized oil was valued via Gas Chromatography-Mass Spectrometry (GC-MS). Some biological tests were done including antibacterial action versus Helicobacter pylori, anti-biofilm activity versus H.

It is thought to be risk-free, environmentally benign, and safe for biological processes to produce zinc oxide nanoparticles from renewable resources. This study examined Cassia javanica's ability to create ZnONPs. The generated ZnONPs were analyzed using a variety of techniques, such as TEM, FTIR spectroscopy, UV-Vis spectroscopy, and XRD analysis.

Background: Diabetic nephropathy is one of the consequences of diabetes mellitus that causes a continuous decline in the eGFR. After the COVID-19 pandemic, studies have shown that patients with diabetic nephropathy who had contracted COVID-19 have higher rates of morbidity and disease progression. The aim of this study was to systematically review the literature to determine and understand the effects and complications of SARS-CoV-2 on patients with diabetic nephropathy.

Article Synopsis
  • Biosurfactants are unique molecules produced by microorganisms that have antiviral properties, prompting their study in connection with HIV and Zika viruses, which can be transmitted from mother to child.
  • Researchers screened halophilic bacteria from Egypt's Red Sea for biosurfactants, identifying strain JBS1 as the most effective in oil displacement and emulsification tests.
  • The study used advanced computer techniques like molecular docking to evaluate the potential of biosurfactants as antiviral drugs, finding promising results with complexes that showed safety and adherence to drug development guidelines.

Background: Given the sparse data on the renin-angiotensin system (RAS) and its biological effector molecules ACE1 and ACE2 in pediatric COVID-19 cases, we investigated whether the ACE1 insertion/deletion (I/D) polymorphism could be a genetic marker for susceptibility to COVID-19 in Egyptian children and adolescents.

Methods: This was a case-control study included four hundred sixty patients diagnosed with COVID-19, and 460 well-matched healthy control children and adolescents. The I/D polymorphism (rs1799752) in the ACE1 gene was genotyped by polymerase chain reaction (PCR), meanwhile the ACE serum concentrations were assessed by ELISA.

Background: Otitis externa and otitis media are two types of ear infections that affect people of all ages, although they are more common in newborns and young children. Antibiotic usage, healthcare, and advanced age all play a role in the development of this illness.

Methods: Fifty-eight patients with various kinds of infections of the ears were voluntary patients attending the outpatient clinics of the Prince Mutaib Bin Abdulaziz Hospital in Sakaka, Al Jouf, Saudi Arabia, examined to evaluate the role of bacteria and the likely significance of plasmids in their antibiotic resistance as ear infectious agents.

Hypervirulent (hvKp) is a new emerging variant of that is increasingly reported worldwide. The variant hvKp is known to cause severe invasive community-acquired infections such as metastatic meningitis, pyogenic liver abscesses (PLA) and endophthalmitis, but its role in hospital-acquired infections (HAIs) is little known. The aim of this study was to evaluate the prevalence of hvKp among hospital-acquired (HA) infections in the intensive care unit (ICU) and to compare between hvKp and classical (cKP) regarding antimicrobial resistance pattern, virulence and molecular characteristics.

Background: Given the sparse data on vitamin D status in pediatric COVID-19, we investigated whether vitamin D deficiency could be a risk factor for susceptibility to COVID-19 in Egyptian children and adolescents. We also investigated whether vitamin D receptor (VDR) FokI polymorphism could be a genetic marker for COVID-19 susceptibility.

Methods: One hundred and eighty patients diagnosed to have COVID-19 and 200 matched control children and adolescents were recruited.
