Journal of Infectious Diseases, 2013 BACKGROUND The degree to which human immunodeficiency virus (HIV) continues to replicate during antiretroviral therapy (ART) is controversial. We conducted a randomized, double-blind, placebo-controlled study to assess whether raltegravir intensification

On the true fractions of repeating and non-repeating FRB sources [PDF]
, 2020 Observationally, fast radio bursts (FRBs) can be divided into repeating and apparently non-repeating (one-off) ones. It is unclear whether all FRBs repeat and whether there are genuine non-repeating FRBs. We attempt to address these questions using Monte Carlo simulations.

Diversity of the HIV-1 Long Terminal Repeat Following Mother-to-Child Transmission [PDF]
, 2000 A study of the human immunodeficiency virus Type 1 (HIV-1) 5′ long terminal repeat (LTR) was performed to determine the extent of variation found within the LTR from 19 mother–infant pairs in Tanzania and to assess whether the LTR is useful in ...

New insights into nested long terminal repeat retrotransposons in Brassica species.
Molecular Plant, 2013 Long terminal repeat (LTR) retrotransposons, one of the foremost types of transposons, continually change or modify gene function and reorganize the genome through bursts of dramatic proliferation. Many LTR-TEs preferentially insert within other LTR-TEs,

Terminal-repeat retrotransposons with GAG domain in plant genomes : a new testimony on the complex world of transposable elements [PDF]
, 2015 A novel structure of nonautonomous long terminal repeat (LTR) retrotransposons called terminal repeat with GAG domain (TR-GAG) has been described in plants, both in monocotyledonous, dicotyledonous and basal angiosperm genomes.

Helquat dyes targeting G-quadruplexes as a new class of anti-HIV-1 inhibitors
Scientific Reports, 2023 The secondary structure of nucleic acids containing quartets of guanines, termed G-quadruplexes, is known to regulate the transcription of many genes.

A dynamic G-quadruplex region regulates the HIV-1 long terminal repeat promoter.
Journal of Medicinal Chemistry, 2013 G-Quadruplexes, noncanonical nucleic acid structures, act as silencers in the promoter regions of human genes; putative G-quadruplex forming sequences are also present in promoters of other mammals, yeasts, and prokaryotes. Here we show that also the HIV-

Easy over Hard: A Case Study on Deep Learning [PDF]
, 2017 While deep learning is an exciting new technique, the benefits of this method need to be assessed with respect to its computational cost. This is particularly important for deep learning since these learners need hours (to weeks) to train the model. Such long training time limits the ability of (a)~a researcher to test the stability of their conclusion

Characterization of Variant Equine Infectious Anemia Virus Long Terminal Repeat Sequences. [PDF]
, 1996 Equine infectious anemia virus (EIAV) is the causative agent of a persistent disease in horses. The long terminal repeat (LTR) region of EIAV contains the enhancer and promoter elements necessary for transcription of the proviral genome.
