Predicting Iron–Sulfur Cluster Redox Potentials: A Simple Model Derived from Protein Structures Open

Jiyeon Min, Fedaa Ali, Bernard R. Brooks, Barry D. Bruce, Muhamed Amin · 2025

Iron-sulfur (Fe-S) clusters are critical cofactors in metalloproteins, essential for cellular processes such as energy production, DNA repair, enzymatic catalysis, and metabolic regulation. While Fe-S cluster functions are intimately linke…

Zinc Oxide Nanoparticle-Loaded Electrospun Polyvinylidene Fluoride Nanofibers as a Potential Face Protector against Respiratory Viral Infections Open

Hassan Nageh, Merna H. Emam, Fedaa Ali, Nasra F. Abdel Fattah, Mohamed Taha , et al. · 2022

Materials science Chemistry Engineering

ZnO-NPs loaded polyvinylidene fluoride (PVDF) composite nanofibers were fabricated by electrospinning and optimized using different concentrations (0, 2, and 5 wt %) of ZnO-NPs. Characterization techniques, for example, FTIR, SEM, XRD, and…

Computational Approach for Probing Redox Potential for Iron-Sulfur Clusters in Photosystem I Open

Fedaa Ali, Medhat W. Shafaa, Muhamed Amin · 2022

Chemistry Computer science

Photosystem I is a light-driven electron transfer device. Available X-ray crystal structure from Thermosynechococcus elongatus showed that electron transfer pathways consist of two nearly symmetric branches of cofactors converging at the f…

Antiviral activity of chitosan nanoparticles encapsulating silymarin (Sil–CNPs) against SARS-CoV-2 (in silico and in vitro study) Open

Samah A. Loutfy, Ahmed I. Abdel-Salam, Yassmin Moatasim, Mokhtar R. Gomaa, Nasra F. Abdel Fattah , et al. · 2022

Chemistry Medicine

To develop a specific treatment against COVID-19, we investigated silymarin–chitosan nanoparticles (Sil–CNPs) as an antiviral agent against SARS-CoV-2 using in silico and in vitro approaches.

Inhibition of SARS-CoV-2 spike protein entry using biologically modified polyacrylonitrile nanofibers:in vitrostudy towards specific antiviral masks Open

Chemistry Materials science Biology

With the increase in the contagiousness rates of Coronavirus disease (COVID-19), new strategies are needed to protect people and to halt the from the spread of viruses.

Air Quality in Six Northern Indian Cities During Diwali 2020: The Real Tragedy in Disguise Open

Alfred J. Lawrence, Akriti Abraham, Fedaa Ali, Saima Arif, Sadaf Fatima , et al. · 2021

Environmental science Geography Geology

North Indian cities have been highly polluted, especially in winters, which coincide with the Diwali festival. This year, the government imposed ban on the burning of firecrackers. This study was undertaken from 4th-21st November, 2020 to …

The New SARS-CoV-2 Strain Shows a Stronger Binding Affinity to ACE2 Due to N501Y Mutation Open

Fedaa Ali, Amal Kasry, Muhamed Amin · 2021

Biology Medicine

SARS-CoV-2 is a global challenge due to its ability to spread much faster than SARS-CoV, which was attributed to the mutations in the receptor binding domain (RBD). These mutations enhanced the electrostatic interactions. Recently, a new s…
