A Machine Learning Approach for MicroRNA Precursor Prediction in Retro-transcribing Virus Genomes

Journal of Integrative Bioinformatics, 2016
Identification of microRNA (miRNA) precursors has seen increased efforts in recent years. The difficulty in experimental detection of pre-miRNAs increased the usage of computational approaches. Most of these approaches rely on machine learning especially

Prevalence of human T-cell lymphotropic virus types 1 and 2 in blood donors of the Caruaru Blood Center (Hemope)

Revista Brasileira de Hematologia e Hemoterapia, 2013
BACKGROUND: There is difficulty in gathering data on the prevalence of human T-cell lymphotropic virus in blood donors as confirmatory testing is not mandatory in Brazil. This suggests there may be an underreporting of the prevalence.

Biochemical Characterization, Specificity and Inhibition Studies of HTLV-1, HTLV-2, and HTLV-3 Proteases

Life, 2021
The human T-lymphotropic viruses (HTLVs) are causative agents of severe diseases including adult T-cell leukemia. Similar to human immunodeficiency viruses (HIVs), the viral protease (PR) plays a crucial role in the viral life-cycle via the processing of

Alpha Interferon Restricts Human T-Lymphotropic Virus Type 1 and 2 De Novo Infection through PKR Activation [PDF]

Journal of Virology, 2013
ABSTRACT Type I interferon (IFN-I) inhibits the replication of different viruses. However, the effect of IFN-I on the human T-lymphotropic virus type 1 (HTLV-1) viral cycle is controversial. Here, we investigated the consequences of IFN-α addition for different steps of HTLV-1 and HTLV-2 infection.

Telomere Length, Proviral Load and Neurologic Impairment in HTLV-1 and HTLV-2-Infected Subjects

Viruses, 2016
Short or damaged telomeres have been implicated in degenerative conditions. We hypothesized that analysis of telomere length (TL) in human T-cell lymphotropic virus (HTLV) infection and HTLV-associated neuropathy might provide clues to the etiology of ...

Prevalence of Human T-lymphotropic virus type 1 and 2 among blood donors in Manaus, Amazonas State, Brazil [PDF]

Revista do Instituto de Medicina Tropical de São Paulo, 2017
Human T-lymphotropic virus type 1 and 2 (HTLV-1/2) is endemic in Brazil, but few studies have investigated the seroprevalence of HTLV and its subtypes among blood donors in the capital city Manaus, Amazonas State, Brazil.To estimate the seroprevalence of HTLV-1/2 and to identify circulating subtypes among blood donors in Manaus.Blood donors (2001-2003)

Infectious Agents As Markers of Human Migration toward the Amazon Region of Brazil

Frontiers in Microbiology, 2017
Infectious agents are common companions of humans and since ancient times they follow human migration on their search for a better place to live. The study of paleomicrobiology was significantly improved in its accuracy of measurement with the constant ...

Is the human T-cell lymphotropic virus type 2 in the process of endogenization into the human genome?

Journal of Virus Eradication, 2020
Human T-cell lymphotropic virus type 2 (HTLV-2) infection has been shown to be endemic among intravenous drug users in parts of North America, Europe and Southeast Asia and in a number of Amerindian populations.
