Foamy viruses (FV) are the oldest known genus of retroviruses and have persisted in nonhuman primates for over 60 million years. FV are efficiently transmitted, leading to a lifelong nonpathogenic infection. Transmission is thought to occur through saliva, but the detailed mechanism is unknown. Interestingly, this persistent infection contrasts with the rapid cytopathicity caused by FV in vitro...

In this note we give a computer assisted proof showing that the unique (5, 3)Ramsey graph is the unique K5-free graph of order 13 giving Fv(3, 4; 5) 6 13, then we prove that 17 6 Fv(2, 2, 2, 4; 5) 6 Fv(4, 4; 5) 6 23. This improves the previous best bounds 16 6 Fv(4, 4; 5) 6 25 provided by Nenov and Kolev.

BACKGROUND Frequent fruit and vegetable (FV) consumption is protective against some cancers, cardiovascular disease, and other chronic diseases. This study explores self-reported frequency of FV consumption in a nationally generalizable sample of Canadian youth in grades 6-12. METHODS Data from grades 6-12 students who participated in the 2012-2013 Youth Smoking Survey (N = 47,203) were used ...

The role of spreading somatic cell infections with ecotropic MuLV viruses in the induction of plasmacytomas in BALB/cAN pi mice was determined by constructing congenic mice that lacked the gene locus Cv that codes for ecotropic virus. DBA/2 mice that lack Cv on chromosome (chr) 5 carry a closely linked gene Rmcfr that determines resistance to infection with mink cell focus-forming viruses (MCF)...

Factor V (FV) deficiency is a rare bleeding disorder whose genetic basis has been described in a relatively small number of cases. Among a total of 12 genetic defects reported in severely or moderately severe deficient patients, 3 were missense mutations and in no case was the mechanism underlying the deficiency explored at the molecular level. In this study, a homozygous missense mutation at c...

Fv-Fragments of antibodies may dissociate at low protein concentrations and are too unstable for many applications at physiological temperatures. To stabilize Fv-fragments against dissociation, we have tested and compared three different strategies on the Fv-fragment of the well-characterized phosphocholine binding antibody McPC603 expressed and secreted in Escherichia coli: chemical cross-link...

OBJECTIVE To increase fruit and vegetable (FV) consumption of youth in Body Quest: Food of the Warrior (BQ), a childhood obesity prevention program. DESIGN Quasi-experimental. SETTING Supplemental Nutrition Assistance Program-Education eligible schools (n = 60). PARTICIPANTS Third-grade students (n = 2,477). INTERVENTION Treatment groups (n = 1,674) self-reported foods consumed through ...

Neonatal injections of Friend virus (FV) or Gross virus (GV) into rats produced immunological tolerance to the virus-induced tumors. The inoculation of specific immune lymphoid cells into the FV-induced tolerant rats brought about the runting syndrome, whereas the GV-induced tolerance was completely abrogated by the same procedure. To investigate the mechanism of the runting syndrome, rats were...

Schools often offer healthy fruits and vegetables (FV) and healthy entrées. However, children may resist these efforts due to a lack of familiarity with the offerings. While numerous exposures with a food increase its liking, it may be that an exposure to a variety of FV at home leads to greater willingness to select other foods - even those that are unrelated to those eaten at home. As an init...
