Of mice, birds, and men: the mouse ultrasonic song system has some features similar to humans and song-learning birds.
(PLoS One, 2012)
Humans and song-learning birds communicate acoustically using learned vocalizations. The characteristic features of this social communication behavior include vocal control by forebrain motor areas, a direct cortical projection ...
Hetahelical receptor signaling: Beyond the G protein paradigm
(Journal of Cell Biology, 1999-05-31)
Elevation of intact and proteolytic fragments of acute phase proteins constitutes the earliest systemic antiviral response in HIV-1 infection.
(PLoS pathogens, 2010)
The earliest immune responses activated in acute human immunodeficiency virus type 1 infection (AHI) exert a critical influence on subsequent virus spread or containment. During this time frame, components of the innate ...
Transmission of single HIV-1 genomes and dynamics of early immune escape revealed by ultra-deep sequencing.
(PLoS One, 2010-08-20)
We used ultra-deep sequencing to obtain tens of thousands of HIV-1 sequences from regions targeted by CD8+ T lymphocytes from longitudinal samples from three acutely infected subjects, and modeled viral evolution during ...
Male mice song syntax depends on social contexts and influences female preferences.
(Front Behav Neurosci, 2015)
In 2005, Holy and Guo advanced the idea that male mice produce ultrasonic vocalizations (USV) with some features similar to courtship songs of songbirds. Since then, studies showed that male mice emit USV songs in different ...
Safety and immunogenicity of a replication-defective adenovirus type 5 HIV vaccine in Ad5-seronegative persons: a randomized clinical trial (HVTN 054).
(PLoS One, 2010-10-27)
BACKGROUND: Individuals without prior immunity to a vaccine vector may be more sensitive to reactions following injection, but may also show optimal immune responses to vaccine antigens. To assess safety and maximal tolerated ...
Common genetic variation and the control of HIV-1 in humans.
(PLoS Genet, 2009-12)
To extend the understanding of host genetic determinants of HIV-1 control, we performed a genome-wide association study in a cohort of 2,554 infected Caucasian subjects. The study was powered to detect common genetic variants ...
Safety profile of L-arginine infusion in moderately severe falciparum malaria.
(PLoS One, 2008-06-11)
BACKGROUND: L-arginine infusion improves endothelial function in malaria but its safety profile has not been described in detail. We assessed clinical symptoms, hemodynamic status and biochemical parameters before and after ...
Diseased G protein-coupled receptors.
(J Clin Invest, 1993-11)
Convergent differential regulation of parvalbumin in the brains of vocal learners.
(PLoS One, 2012)
Spoken language and learned song are complex communication behaviors found in only a few species, including humans and three groups of distantly related birds--songbirds, parrots, and hummingbirds. Despite their ...
