Influence of infant milk formula processing on protein digestion and gut barrier health in vitro and in vivo
… loads during IMF processing denature native milk proteins, increase protein aggregation and promote the Maillard reaction, with the generation of advanced glycation end products. Denatured and aggregated dairy proteins will be digested differently in the infant gut compared to native dairy …

Toward a microfluidic system for proteomics
… for proteomic analysis. A highly efficient protein digestion microdevice was fabricated using commercially available immobilized trypsin on agarose beads, packed into a silica capillary and connected directly to an electrospray mass spectrometer via a ‘microtight T’ connector, from which …

CHARACTERIZATION OF PROTEIN SOURCES AND THEIR EFFECTS ON BROILER PERFORMANCE, DIGESTIVE TRACT MORPHOLOGY AND CAECAL FERMENTATION METABOLITES
The goal of this thesis was to characterize protein sources and evaluate their effects on broiler performance, digestive tract morphology and caecal fermentation. Understanding the digestion kinetics of high protein ingredients is an important step in elucidating the impact protein sources have on …

Determining the mechanism of pulsed electric field for improving meat quality : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
… The changes in the calpain activity and protein profile of beef from older animals during ageing is poorly explored and further understanding of biochemical processes is needed to design useful approaches for tenderization. Relatively few experiments have examined the effects of ageing on …

The whole-body protein turnover response to the ingestion of intrinsically labeled eggs at rest and after endurance exercise
… been on the ingestion of dietary or supplemental protein to maximize skeletal muscle protein synthesis to facilitate remodeling (e.g., growth and repair of muscle). However, considerably less attention has been paid to the repletion of exercise-induced oxidative losses at the whole-body level. …

Assessing and Implementing Value-Added Soybean Innovations in the Soybean Meal and Food Industry
… of trypsin inhibitors (TIs) - antinutritional proteins that impair protein digestion in monogastric animals. This study employed a multifaceted approach combining phenotyping, genome editing, and association mapping to enhance soybean quality. First, we developed near-infrared reflectance …

Intragastric gelation of mixed soy protein isolate and alginate as well as its effect on postprandial glucose response and satiety
… alginate on sucrose release and in vitro gastric digestion of soy protein isolate (SPI) in model beverages as well as to determine whether consumption of the model beverages would affect postprandial blood glucose response and appetite in healthy adults. Model beverages containing 5% w/v SPI, 0 to …

Using Data Analytics in Agriculture to Make Better Management Decisions
… affect measurements associated with ruminant protein digestion. Measurements explored were 0-h washout, potentially degradable, and undegradable protein fractions, protein degradation rate and digestibility of rumen undegradable protein. Our research found that the aforementioned measurements …

Effects of Cysteine Modification on Microtubule-Motor Protein Function and Tubulin Assembly
… been shown to inhibit the activity of MT-motor proteins and tubulin assembly. This project seeks to investigate the mechanisms by which NEM affects motor function and inhibits MT minus end assembly. Recombinant motor domains of Drosophila kinesin (DK350 and DK375), Ncd (MC1), and squid kinesin …

Plant secondary compounds in small ruminant feeding in stall-fed and pastoral system in the Mediterranean
… properties such as reduced palatability and protein digestion but can also have positive effects especially on health. Two systems of lamb meat production were investigated, namely stall-fed in Siciliy and pastoral in Morocco. In the stall-fed system, we investigated the potential of …

THE EFFECT OF DENTAL FLOATING ON NUTRIENT DIGESTION IN NON- PREGNANT QUARTER HORSE MARES
Irregular wear patterns can cause poor feed digestion, weight loss, performance problems, and pain in the horse when wearing a halter or bridle. The objective of this study was to test the hypothesis that dental floating would increase crude protein and fiber digestion in non-pregnant stock-type …

Novel customisable phases for micro solid-phase extraction and automated biological sample preparation
Protein biomarkers play an important role in clinical settings as they serve as measurable indicators for normal or abnormal biological processes. They aid in accelerated disease identification, diagnosis, prognosis, and response to treatments. Recently, mass spectrometry (MS) assays have been …

Regulation of postprandial protein metabolism after food ingestion and exercise
… by counterbalanced fluctuations between protein synthesis and breakdown rates. Protein ingestion has been shown to stimulate protein synthesis rates and thus is an important variable within the net protein balance equation dictating a positive balance. However, postprandial protein …

Novel soybean products fed to weanling pigs
… on the effect that trypsin inhibitors have on protein digestion. The apparent (AID) and standardized (SID) ileal digestibility were determined using low temperature and high temperature-processed full-fat soybeans (FFSB) as well as a low temperature and high temperature-processed low-Kunitz …

Characterisation of the reaction of 1,4-phenylenebismaleimide with Ca²⁺-ATPase and elucidation of the intramolecular crosslink site
… % intramolecularly crosslinked ATPase. Trypsin digestion altered the apparent molecular weight of the 125 kD species to 135 kD, suggesting, in accordance with the results of glutaraldehyde crosslink, that the putative intramolecular crosslink 1s between tryptic fragments A and B. …

Studying self-entangled DNA at the single molecule level
… within the viral capsid, occasionally in proteins, and during the transcription and replication of genomic DNA. Biological knots are similarly thought to change the dynamics of viral ejection, protein digestion, and translocation of biomolecules through nanopores. Despite the prevalence of …

The impact of soybean derived trypsin inhibitor proteins and soybean hulls on nursery and grow-finish pig nutrient digestibility, growth performance, and carcass composition
… known that antinutritional protease inhibitor proteins are innate in soybean ingredients, the specific activity of these proteins in the complete feed that attenuates pig performance and health is limited. Therefore, the overall objective of this dissertation was to evaluate optimizing growth …
