Dynamics of Positive Frequency Dependent Selection Triggers Selection for Silence

Autor: I. Hashem, V. De Buck, J. Van Impe

Publikováno v: Complexity, Vol 2022 (2022)

Positive frequency dependent selection is a natural selection regime where the fitness of a phenotype increases with its frequency in the population. Examples can be typically found in the spread of disease tolerance strategies in a population. A cha

The Silent Cooperator: An Epigenetic Model for Emergence of Altruistic Traits in Biological Systems

Autor: I. Hashem, D. Telen, P. Nimmegeers, J. Van Impe

Publikováno v: Complexity, Vol 2018 (2018)

Spatial evolutionary game theory explains how cooperative traits can survive the intense competition in biological systems. If the spatial distribution allows cooperators to interact with each other frequently, the benefits of cooperation will outwei

Synthesis and cytotoxicity evaluation of novel 1,8-acridinedione derivatives bearing phthalimide moiety as potential antitumor agents

Autor: Hassan A. Khatab, Sherif F. Hammad, Esmail M. El‐Fakharany, Ahmed I. Hashem, Eman A. E. El-Helw

Publikováno v: Scientific Reports, Vol 13, Iss 1, Pp 1-21 (2023)

Abstract In this study, we aimed to develop hybrid antitumor compounds by synthesizing and characterizing novel N-substituted acrididine-1,8-dione derivatives, designed as hybrids of phthalimide and acridine-1,8-diones. We employed a three-step synth
