To determine the functional homology between phytochromes from evolutionarily divergent species, we used the cauliflower mosaic virus 35S promoter to express a monocot (oat) phytochrome cDNA in a dicot plant (tomato). Immunoblot analysis shows that more than 50% of the transgenic tomato plants synthesize the full-length oat phytochrome polypeptide. Moreover, leaves of light-grown transgenic pla...

BACKGROUND Osteochondral autograft transfer (OAT) aims at restoring normal articular cartilage surface geometry and articular contact mechanics. To date, no studies have evaluated the contact mechanics of the canine stifle following OAT. Additionally, there are no studies that evaluated the role of the meniscus in contact mechanics following OAT in human or canine femorotibial joints. The objec...

The State of Rio Grande do Sul (RS) is the largest producer of oat in Brazil with the aid of consolidated breeding programs, which are constantly releasing new cultivars. The main objectives of this study were to: 1) evaluate the annual genetic progress in grain yield and hectoliter weight of the oat cultivars in RS, with and without fungicide use on aerial parts of plants; and 2) evaluate the ...

Oral anticoagulation is an effective prophylactic or treatment measure for many indications (Baglin et al, 2005). Most patients on oral anticoagulant therapy (OAT) take the drug warfarin. This article discusses how OAT is monitored, the factors affecting the stability and control of anticoagulation, and the importance of educating patients who are on OAT.

Acceptance of and preference for a particular food depends not only on its intrinsic (e.g. nutritional) properties but also on expected or recent food experiences. An instance of this type of phenomenon has been called induction effect, which consists of an increased intake of a type of food when it precedes a hedonically preferred food in a sequence familiar to the animal, relative to controls...

Recent evidence suggests that infertile males donating semen for intracytoplasmic sperm injection (ICSI) may be at an increased risk of transmitting numerical (predominantly sex chromosome) abnormalities to their offspring. The present study was designed to determine aneuploidy in spermatozoa from oligoasthenoteratozoospermic (OAT) patients undergoing ICSI. Aneuploidy frequencies of 12 autosome...

Oat bran lowers serum lipid concentrations in healthy and hyperlipidemic subjects. To determine the effects of a ready-to-eat oat-bran cereal on lipid concentrations, we fed control (corn flakes) and oat-bran cereal diets for 2 wk to 12 men with undesirably high serum total-cholesterol concentrations. Subjects were randomly assigned to one of the two diets upon admission to the metabolic ward. ...

Abstract A total of 24 oat genotypes were evaluated across 9 environments using a randomized complete block design with 3 replications. The combined analysis variance indicated that grain yield was significantly affected by genotype, environment, and genotype environment interaction (GEI). environment's main effect explained 44.62% the variation, whereas GEI captured 28.84% 26.54%, respectively...

Genetic variation for fitness-relevant traits may be maintained in natural populations by fitness differences that depend on environmental conditions. For herbivores, plant quality and variation in chemical plant defences can maintain genetic variation in performance. Apart from plant secondary compounds, symbiosis between plants and endosymbiotic fungi (endophytes) can produce herbivore-toxic ...

in order to study of nitrogen absorb and use efficiency of wheat (triticum aestivum) and wild oat (avena fatua) at vegetative growth stage, a factorial experiment was conducted based on completely randomized block design with three replications in research greenhouse of faculty of agriculture, at ferdowsi university of mashhad in 2008. the first factor was competition between wild oat (densitie...
