Previous steady-state continuous-feeding studies have shown that the gut mucosa removes substantial amounts of both dietary and systemic amino acids. However, enteral nutrition is often given under non-steady-state conditions as a bolus meal, and this has been shown to influence systemic metabolism. Therefore, our aim was to quantify the relative metabolism of dietary and systemic lysine by the...

Non-crop plants such as grasses and volunteer are an inseparable part of the flora crop fields can influence virus incidence in plants. The presence reservoirs lead to a higher probability However, role inoculum source agricultural has not been well studied for many viral diseases crops. Grasses have found constitute potential cereal-infecting viruses different parts world. This study revealed ...

About 20 % of ruminal microbial N in dairy cows derives from purines and pyrimidines; however, their intermediary metabolism and contribution to the overall N metabolism has sparsely been described. In the present study, the postprandial patterns of net portal-drained viscera (PDV) and hepatic metabolism were assessed to evaluate purine and pyrimidine N in dairy cows. Blood was sampled simultan...

Various cytopathological structures, known as inclusion bodies, are formed upon infection of cultured leafhopper cells by Rice dwarf virus, a member of the family Reoviridae. These structures include tubules of approximately 85 nm in diameter which are composed of the nonstructural viral protein Pns10 and contain viral particles. Such tubular structures were produced in heterologous non-host in...

In current study, phagocytosis product (PP) of peripheral blood monocytes was detected among 920 dwarf chickens (460 per sex) at 20 wk of age, and based on discrepancies of PP, the flock was grouped (the highest group, the medium group, and the lowest group). Then serum hemagglutination inhibition antibody titers and subpopulations of T-lymphocytes of each group were examined after inoculations...

The uncertainty in the variables and functions in computer simulations can be quantified by probability distributions and the correlations between the variables. We augment the standard computer arithmetic operations and the interval arithmetic approach to include probability distribution variable (PDV) as a basic data type. Probability distribution variable is a random variable that is usually...

The effect of feeding v. fasting, on tissue blood flow, oxygen uptake and proportional contributions of the portal drained viscera (PDV), liver (Expts 1 and 2) and hindquarters (HQ; Expt 2) to whole-body 0, uptake were studied in beef steers. The combined techniques of indirect calorimetry and net tissue flux, the latter being the product of arterio-venous concentration difference and blood flo...

UNLABELLED Summary Barley yellow dwarf virus (BYDV), the most economically important virus of small grains, features highly specialised relationships with its aphid vectors, a plethora of novel translation mechanisms mediated by long-distance RNA interactions, and an ambiguous taxonomic status. The structural and movement proteins of BYDV that confer aphid transmission and phloem-limitation pro...

The complete nucleotide sequence of segment 5 (S5) of the rice dwarf virus (RDV) genome was determined. RDV S5 is 2571 bp in length and has a single long open reading frame which encodes a polypeptide of 801 amino acids (Mr 90495). When compared to the wound tumor virus genome S5, there was 56.9% and 52.8% similarity in the nucleotide and amino acid sequences, respectively. This high similarity...
