The interaction between dietary crude protein and amino acid levels in weaner pigs in an antibiotic-free environment with or without Bacillus amyloliquefaciens supplementation
The interaction between dietary crude protein and amino acid levels in weaner pigs in an antibiotic-free environment with or without Bacillus amyloliquefaciens supplementation Natasha van Niekerk High crude protein (CP) diets cause a myriad of digestive problems in weaner pigs due to incomplete …

Responses of Two Strains of Broilers to Diets Varying in Essential Amino Acid Density and Energy Levels
… strains of broilers to diets varying in overall amino acid levels and metabolizable energy levels were observed. Amino acid levels used were 80%, 90%, 100%, 110%, 120%, and 130% of Ross recommended minimum digestable levels of essential amino acids. Energy levels used were either below or above …

Characterization of the Pathway Leading to the Synthesis of Salicylic Acid in Plants Resisting Pathogen Infection.
<p>Salicylic acid is a plant hormone that accumulates with plant-pathogen interaction. This accumulation corresponds to the plant being resistant to infection and without it the plant is susceptible. In this study, primers of genes involved in the normal synthesis of SA were used in RT-PCR to …

Amino acids regulate the transcription, internal sorting, and intrinsic activity of the general amino acid permease (GAP1) in S. cerevisiae
The high capacity general amino acid permease in Saccharomyces cerevisiae (GAP1) is regulated such that it actively imports amino acids into the cell from the extracellular medium only when internal amino acid levels are low. Regulation of activity allows the cell to rapidly and reversibly modulate …

Transport activity dependent regulation of the yeast general amino acid permease
The general amino acid permease Gap1p of Saccharomyces cerevisiae scavenges amino acids from the extracellular medium for use as nitrogen sources in starvation conditions. Because unlimited uptake of both naturally occurring amino acids and amino acid analogs is toxic, Gap1p is active at the plasma …

Effect of metabolic insult on amino acids in the ciliary epithelium, lens, and retina
… of ocular ischaemia is to determine changes in amino acids likely to be modified due to the intricate interrelationship between cellular metabolism and these compounds. Such an approach, using quantitative silver-intensified immunogold detection of a range of immunoglobulins, can provide a …

THE STUDY OF THE DISSOLVED NITROGEN CONTAINING MACROMOLECULES IN THE MARINE ENVIRONMENT
… direct determination of the dissolved combined amino acid (DCAA) content of seawater involving the acid hydrolysis of seawater under specified conditions, followed by the determination of the amino acids by reverse phase liquid chromatography (RPLC). No preconcentration or co-precipitation steps …

The effect of nutrition and environment on broiler type chickens
Influence of light, dietary amino acid levels, feeding space, and ambient temperature on male broiler body weight, feed efficiency, percentage abdominal fat, and incidence and severity of leg abnormalities was studied in two experiments. Broilers subjected to intermittent light (1 hr on:2 hrs off) …

The Effect of Protein Blend Supplementation and Resistance Exercise on Skeletal Muscle Growth and Adaptation
… proteins (protein “blend”) with different amino acid release profiles will prolong amino acid levels in the blood leading to increased muscle growth during resistance exercise-training (RET) as compared to a commonly used single protein source. I tested this hypothesis in the acute and …

Possible Role of the Hypothalamic Melanocortin System to Induce Satiety by High Protein/low Carbohydrate Diets
… though no clear association between plasma amino acid levels and food intake were apparent. Finally, we sought to establish a causal association between increased melanocortin activity in the MBH and the reduction in food intake of high protein diets by evaluating the affects of a …

Avian Infectious Bronchitis Virus: A Tropism for the Rooster Reproductive Tract and Effects on Reproductive Performance
… Third, seminal plasma protein patterns and free amino acid levels are altered in vaccinated roosters when compared to non-vaccinated roosters. Fourth, differentially expressed seminal plasma proteins were identified in vaccinated roosters when compared to non-vaccinated roosters. These data …

Plasticity of Primary Metabolism in Parasitic Orobanchaceae
… Arabidopsis thaliana hosts that had mutations in amino acid metabolism but otherwise identical genetic backgrounds. Comparison of P. aegyptiaca and T. versicolor metabolite profiles identified substantial differences in the stages spanning the transition from pre-haustorial development through …

Expression and Function of the Chloroplast-encoded Gene matK
… evolving gene at nucleotide and corresponding amino acid levels. The high number of nucleotide substitutions and length mutations in matK has provided a strong phylogenetic signal for resolving plant phylogenies at various taxonomic levels. However, these same features have raised questions as …

The Phylogenetic Reconstruction of the Grass Family (Poaceae) Using matK Gene Sequences
… that can be used at different taxonomic levels from the tribal to the division levels. It also has demonstrated the potential of partial sequencing in resolving systematic relationships from the tribe to the division level. The matK gene in the Poaceae was characterized with complete …

Characterization of a Newly Identified Alphavirus, Eilat Virus
… sequence divergence at the both nucleotide and amino acid levels. Phylogenetic analyses placed EILV basal to the western equine encephalitis antigenic complex within the main clade of mosquito-borne alphaviruses. Electron microscopy revealed that, like other alphaviruses, EILV virions are …
