Human immunodeficiency virus (HIV)-infected patients are at an increased risk of co-infection with human papilloma virus (HPV), and subsequent malignancies such as oral cancer. To determine the role of HIV-associated immune suppression on HPV persistence and pathogenesis, and to investigate the mechanisms underlying the modulation of HPV infection and oral cancer by HIV, we developed a mathemat...

background : main technique to control acquired immunodeficiency syndrome (hiv) infection is the effective preventive programs among high-risk groups. modeling is one of the effective methods where there is inadequate data. we used the modes of transmission (mot) model to predict the transmission of hiv infection in iran. methods : we systematically searched published and grey literature to fin...

In [17] it was introduced a model to describe the dynamics of the HIV infection when the patient is under chemotherapy (either RTI or PI). The main idea in [17] was to introduce the effectiveness of the drug as a dynamical variable. In this paper we pursue this idea starting from an analysis of the fitness of the virus during the therapy. We introduce an adaptive model in which the ability of t...

Human immunodeficiency virus infection destroys the body immune system, increases the risk of certain pathologies, damages body organs such as the brain, kidney, and heart, and causes death. Unfortunately, this infectious disease currently has no cure; however, there are effective retroviral drugs for improving the patients' health conditions but excessive use of these drugs is not without harm...

conclusions we found a large impact due to nsps for reducing the occurance of hiv among active drug injectors who have been provided sufficient needles and syringes. the coverage of nsps needs to be increased to observe such significant impact. results given the output of the model, we found that among the pwid with sufficient coverage of nsps the hiv rate is 1.02%, while those with insufficien...
