The effect of resistance exercise with the ingestion of supplementary protein on the activation of the mTOR cascade, in human skeletal muscle has not been fully elucidated. In this study, the impact of a single bout of resistance exercise, immediately followed by a single dose of whey protein isolate (WPI) or placebo supplement, on the activation of mTOR signalling was analyzed. Young untrained...

Heat pre-treated and non heat pre-treated whey protein isolate (WPI) were hydrolysed using α-chymotrypsin (chymotrypsin), pepsin and trypsin. The in vitro antioxidant activity, ACE-inhibition activity and surface hydrophobicities of the hydrolysates were measured in order to determine if peptides with dual functionalities were present. Dual functional peptides have both biological (e.g. antioxi...

Metacercarial antigen of Fasciola gigantica was evaluated for early immunodiagnosis of experimental bovine fasciolosis using ELISA and Western blot. In ELISA, the experimental F. gigantica infection was detected as early as 2 weeks post-infection (WPI). The gradual increasing trend of antibody level was observed from 2 to 7 WPI, followed by a plateau, which was maintained up to 14 WPI. In Weste...

Helicobacter pylori infection results in chronic gastritis, which may progress to gastric cancer. In this study, we investigated the efficacy of H. pylori eradication in preventing the progression of gastritis to gastric cancer in H. pylori-infected transgenic INS-GAS mice. H. pylori infection induced severe dysplasia and gastric cancer classified as high-grade and low-grade gastrointestinal in...

The aim of this work is to understand the effects of the rheological and interfacial properties of a model food on continuous foaming operation in laminar flow conditions. The rheological properties of food model (glucose syrup) were adjusted using three polysaccharides: xanthan, LM pectin and guar. Interfacial properties were varied using two kinds of proteins: Na-caseinates and whey proteins ...

A glue stick is comprised of solidified adhesive mounted in a lipstick-like push-up tube. Whey is a byproduct of cheese making. Direct disposal of whey can cause environmental pollution. The objective of this study was to use whey protein isolate (WPI) as a natural polymer along with polyvinylpyrrolidone (PVP) to develop safe glue sticks. Pre-dissolved WPI solution, PVP, sucrose, 1,2-propanedio...

The Hexi Corridor, an important part of the Silk Road Economic Belt, is considered the poorest, most water scarce, and most ecologically fragile area in China. Establishing efficient strategies for water management in an integrated manner is utterly important. This paper evaluates the spatio-temporal trends of water stress (2003–2015) in the Shule (SLRB), Heihe (HHRB), and Shiyang (SYRB) River ...

Dairy fouling is a ubiquitous problem in food processing, however, the mechanism not fully understood and investigations arose mainly from experiments with model systems that contained only whey proteins, typically reconstituted protein isolate powder (WPI). The effect of casein on has been rarely considered despite it major component milk proteins. To fill this gap, protein-based fluids contai...

A novel versatile biocompatible hydrogel of whey protein isolate (WPI) and two types tannic acid (TAs) was prepared by crosslinking WPI with TAs in a one-step method at high temperature for 30 min. is one common protein-based preparation which used formation. The obtained WPI-TA hydrogels were disc form retained their integrity after sterilization autoclaving. Two TA preparations differing mole...
