The sequencing of multiple genomes of the same plant species has revealed polymorphic gene and exon loss. Genes associated with disease resistance are overrepresented among those showing structural variations, suggesting an adaptive role for gene and exon presence–absence variation (PAV). To shed light on the possible functional relevance of polymorphic coding region loss and the mechanisms dri...

With twenty-five G-protein-coupled TAS2R receptors bitterness is the most complex taste sensation in terms of signal transduction. The objective of this sensory study was to investigate the effect of hTAS2R38 bitter receptor gene genotypes on intensity of bitterness of different N-C=S containing compounds. In addition, we studied the bitterness of vegetables that produce glucosinolates, which a...

Porcine adenovirus-3 (PAV-3) was developed as an expression vector using homologous recombination in Escherichia coli BJ 5183. As a prerequisite, the complete genome of PAV-3 was first introduced as a PacI restriction fragment into a bacterial plasmid. The plasmid, when PacI restricted and transfected into swine testicular cells, produces an infectious virus. The potential of this procedure was...

BACKGROUND/AIMS The influence of TAS2R38 haplotype on the relationship between the perceived intensity of propylthiouracil (PROP) and the basic tastes of salt, sweet, sour, and bitter (quinine) was evaluated in the Beaver Dam Offspring Study. METHODS Genotyping was performed on 1,670 participants aged ≥45 years (mean age = 54.4; range = 45-84), and suprathreshold taste intensity was measured ...

Research interest often lies in comparing structural model specifications implying different relationships among latent factors. In this context parceling is commonly accepted, assuming the item-level measurement structure is well known and, conservatively, assuming items are unidimensional in the population. Under these assumptions, researchers compare competing structural models, each specifi...

BACKGROUND Refinement of ventilatory techniques remains a challenge given the persistence of chronic lung disease of preterm infants. METHODS To test the hypothesis that proportional assist ventilation (PAV) will allow to lower the ventilator pressure at equivalent fractions of inspiratory oxygen (FiO(2)) and arterial hemoglobin oxygen saturation in ventilator-dependent extremely low birth we...

Bibliographic information networks, formed by online bibliographic databases, such as ACM Digital Library and IEEE/IET Electronic Library, contain abundant information about authors, papers, venues (journals/conferences), and have been widely studies in recent years. However, few studies examine the problem of ranking objects in these networks. In this paper, we study this problem and present a...

We investigated the role of Pav-KLP, a kinesin-6, in the coordination of spindle and cortical dynamics during mitosis in Drosophila embryos. In vitro, Pav-KLP behaves as a dimer. In vivo, it localizes to mitotic spindles and furrows. Inhibition of Pav-KLP causes defects in both spindle dynamics and furrow ingression, as well as causing changes in the distribution of actin and vesicles. Thus, Pa...

Barley yellow dwarf virus (BYDV) species PAV occurs frequently in irrigated wheat fields worldwide and can be efficiently transmitted by aphids. Isolates of BYDV-PAV from different countries show great divergence both in genomic sequences and pathogenicity. Despite its economical importance, the genetic structure of natural BYDV-PAV populations, as well as of the mechanisms maintaining its high...
