The aim of the present paper is to formulate two new mathematical models describe co-dynamics severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and human T-cell lymphotropic virus type-I (HTLV-I) in a host. characterizes interplaying between seven compartments, uninfected ECs, latently SARS-CoV-2-infected actively free SARS-CoV-2 particles, CD4+T cells, HTLV-I-infected cells cells. i...

Human T-cell lymphotropic virus type 1 (HTLV-1) is associated with adult T-cell leukemia/lymphoma (ATL) and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). Only a limited percentage of infected individuals develop disease in response to the virus while the majority remain asymptomatic and HAM/TSP is the most common clinical manifestation of the virus. HAM/TSP is an inflamma...

Desde o descobrimento e caracterização do retrovírus (HTLV-i) a sua associação com algumas neoplasias de células T periféricas, muitos avanços foram alcançados quanto aos aspectos etiopatológicos da leucemia/linfoma adulto (LLTA). Estudos soroepidemiológicos anti-HTLV-I realizados em diversas partes mundo demonstraram que: HTLV-I é agente etiológico LLTA paraparesia espástica tropical (TSP); te...

  Objective(s): HTLV-I and HIV virus quantification is an important marker for assessment of virus activities. Since there is a direct relationship between the number of virus and disease progression, HTLV- I and HIV co-infection might have an influence on the development of viral associated diseases, thus, viral replication of these viruses and co-infection were evaluated.   Materials and...

Background and Aims: Human T-lymphotropic virus (HTLV) is a human retrovirus which has been known to cause adult T-cell leukemia/lymphoma and some other inflammatory disorders. Patients with hereditary bleeding diseases are at high risk for these viruses. In this study, we evaluated serological HTLV-I/II infection among these patients in west Azerbaijan of Iran. Material and Methods: We stud...

Background: The northeast of Iran is one the endemic regions human T-cell lymphotropic virus type-1 (HTLV-1). This study aimed to evaluate relationship between nasopharyngeal carcinoma and HTLV-1 infection in Iran, an area for HTLV-1. Methods: In this case-control study, paraffin-embedded tissue samples patients with definitive were evaluated presence genome by polymerase chain reaction retrosp...

Background: Retroviruses of human T-lymphotropic viruses (HTLV-1 and HTLV-2) have been demonstrated to be endemic in the north-eastern region of Iran. This study aims to determine HTLV-1 and HTLV-2 prevalence among healthy individuals in Neyshabur City during 2010-2014. Methods: A total of 8054 blood samples were collected from healthy participants in Neyshabur, North-Eastern Iran. The blood sa...

Abstract In contemporary history, several forms of civil society organizations have stood out in the struggle to expand rights. Non-governmental dedicate themselves extending rights group for which they were created. This study shows work HTLVida NGO introduce HTLV governmental agenda Bahia State, Brazil, and extend this population. is a retrovirus affecting T lymphocytes can cause neurological...
