Identification of potential antiviral compounds from Egyptian sea stars against MERS-CoV with the in vitro and in silico experiments
Nat Prod Res. 2024 Apr 2:1-7. doi: 10.1080/14786419.2024.2335361. Online ahead of print.ABSTRACTRecently, the world faced many epidemics which were caused by viral respiratory pathogens. Marine creatures including Asteroidea class have been one of the recent research topics due to their diverse and complex secondary metabolites. Some of these constituents exhibit antiviral activities. The present study aimed to extract and identify the potential antiviral compounds from Pentaceraster cumingi, Astropecten polyacanthus and Pentaceraster mammillatus. The results showed that promising activity of the methanolic extract of P. c...

Sensors, Vol. 24, Pages 2268: Analysis of the Photogrammetric Use of 360-Degree Cameras in Complex Heritage-Related Scenes: Case of the Necropolis of Qubbet el-Hawa (Aswan Egypt)
This study shows the results of the analysis of the photogrammetric use of 360-degree cameras in complex heritage-related scenes. The goal is to take advantage of the large field of view provided by these sensors and reduce the number of images used to cover the entire scene compared to those needed using conventional cameras. We also try to minimize problems derived from camera geometry and lens characteristics. In this regard, we used a multi-sensor camera composed of six fisheye lenses, applying photogrammetric procedures to several funerary structures. The methodology includes the analysis of several types of spherical...

Radioactive and mineralogical assessment of mediterranean black sands: a systematic analysis and health risk evaluation
This study investigates the naturally occurring radionuclides in Egyptian black sands collected from the Mediterranean Sea Coast, an area rich in sediments from the White Nile, Blue Nile, and Atbara rivers. The black sands mainly comprise two groups of minerals: the gangue group, consisting of quartz, feldspar, amphiboles, pyroxenes, epidote, and micas, and the economic minerals group, which includes magnetite, garnet, zircon, monazite, and uncommon commercial minerals like thorite. A gamma spectrometry with a NaI (Tl) detector was employed to analyze black sand samples for the presence of radionuclides. Additionally, radi...

The role of polymorphic cytochrome P450 gene (CYP2B6) in B-chronic lymphocytic leukemia (B-CLL) incidence and outcome among Egyptian patients
In conclusion, our findings showed that the CYP2B6*9 (G516T) polymorphism is associated with B-CLL susceptibility among Egyptian patients. This variant greatly affected the clinical outcome and can serve as a good therapeutic marker in predicting response to cyclophosphamide treatment.PMID:38560574 | PMC:PMC10972729 | DOI:10.32604/or.2024.047021 (Source: Oncology Research)
