Trans vaccenic acid (TVA; trans-11 18:1) is a positional and geometric isomer of oleic acid and it is the predominant trans isomer found in ruminant fats. TVA can be converted into cis-9, trans-11 conjugated linoleic acid (c9, t11-CLA), a CLA isomer that has many beneficial effects, by stearoyl CoA desaturase 1 (SCD1) in the mammary gland. The health benefits associated with CLA are well docume...

For successful infection, avian sarcoma leukosis virus subgroup A (ASLV-A) requires its receptor, tumor virus A (TVA), to be present on the surface of target cells. This is the basis of the RCAS-TVA gene delivery system: Mammalian cells lack the gene encoding TVA and are normally resistant to infection by ASLV; however, transgenic targeting of TVA to specific cell types or tissues in the mouse ...

The group of avian sarcoma and leukosis virus (ASLV) in chickens contains six highly related subgroups, A to E and J. Four genetic loci, tva, tvb, tvc and tvj, encode for corresponding receptors that determine the susceptibility to the ASLV subgroups. The prevalence of ASLV in hosts may have imposed strong selection pressure toward resistance to ASLV infection, and the resistant alleles in all ...

The TVA has long been held in high esteem for its programs designed to reduce malaria mortality and morbidity rates in the Southeast following its establishment in 1933. One reason why the TVA developed the anti-malaria programs was that they created large bodies of standing water by damming up the Tennessee River and its tributaries. Given the recent increase in river system management project...

The Theory of Visual Attention (TVA; Bundesen, 1990) is a comprehensive quantitative account of visual attention, which accounts for many empirical findings and has been extensively applied to clinical studies of attention. According to TVA, perceptual processing of objects occurs in parallel constrained by a limited processing capacity or rate, which is distributed among target and distractor ...

Trading Volume Activity (TVA) indicates the amount of stock trading volume in a company's market. Companies with good and financial performance can increase volume. The research aims to empirically examine effect retained earnings on Return On Assets (ROA) as moderating variable. study uses data from 2018-2020 statements companies consumption construction services sector listed IDX analyzed usi...

BACKGROUND Tricuspid regurgitation (TR) is an important predictor of morbidity and mortality in heart failure. We aimed to examine the 3D geometry of the tricuspid valve annulus (TVA) in patients with functional TR, comparing them with patients with normal tricuspid valve function and relating annular geometric changes to functional TR. METHODS AND RESULTS TVA shape was examined by real-time ...

We compared the physiological and morphological responses of rooted cuttings of Populus trichocarpa Torr. & Gray and P. trichocarpa x P. deltoides Bartr. ex Marsh. grown in either near-ambient solar ultraviolet-B (UV-B; 280-320 nm) radiation (cellulose diacetate film) or subambient UV-B radiation (polyester film) for one growing season. Midday biologically effective UV-B radiation was 120.6 and...

Site- and time-specific somatic gene transfer by using the avian sarcoma-leukosis retrovirus RCAS (replication-competent avian sarcoma-leukosis virus long terminal repeat with splice acceptor) has been shown to be a powerful tool to analyze gene function in vivo. RCAS retroviruses that express the avian subgroup A envelope transduce only mammalian cells genetically engineered to express the avi...

PURPOSE Traditional balloon kyphoplasty (BK) is a common treatment for symptomatic vertebral compression fractures. The purpose of this study was to compare a novel vertebral augmentation technique, radiofrequency-targeted vertebral augmentation (RF-TVA), to BK for restoration of vertebral height, cavity creation, and polymethylmethacrylate (PMMA) delivery and interdigitation into the surroundi...
