<i>FOXP3 (rs 3761548)</i> and <i>BRAF (V600E</i> ) gene polymorphism among Egyptians with hepatocellular carcinoma Open
Hepatocellular carcinoma (HCC) is a universal problem. The risk factors for HCC could either be environmental or host-genetic-related. The polymorphism of both FOXP3 (rs3761548) and BRAF (V600E) genotypes and alleles was studied in 104 Egy…

An SIS sex-structured influenza A model with positive case fatality in an open population with varying size Open
This work aims to study the role of sex disparities on the overall outcome of influenza A disease. Therefore, the classical Susceptible-Infected-Susceptible (SIS) endemic model was extended to include the impact of sex disparities on the o…

Role of Differential Susceptibility and Infectiousness on the Dynamics of an SIRS Model for Malaria Transmission Open
A deterministic model for the transmission dynamics of SIRS-type malaria in hosts and SI in mosquito populations is proposed. The host population is differentiated between naive, primary, and secondary susceptible individuals. Primary and …
