Summary: This study investigates the dynamic mobility spectra of nanoemulsion drops in polyacrylamide hydrogels using electrokinetic sonic amplitude. The nanodrop radius in hydrogels is found to be similar to their nanoemulsion counterparts, with frequency-independent shear viscosity and shear modulus. The low-frequency plateau modulus systematically increases with the hexadecane volume fraction.

Summary: The aim of this study was to investigate the influence of different processing methods on the quality, protein oxidation, and structural properties of yak meat. Various parameters such as cooking loss, shear force, color, texture, thiobarbituric acid reactive substance (TBARS), total carbonyl content (TCC), total sulfhydryl content (TSC), and structural properties were measured. The results showed that frying at 80 degrees C resulted in the lowest cooking loss and shear force, indicating better textural characteristics. Drying led to the highest protein oxidation, while frying showed the lowest protein oxidation and the best quality.

Summary: This manuscript describes the formation mechanism of an artifact shoulder peak in a therapeutic recombinant protein X during the sample preparation procedure under standard non-reduced capillary electrophoresis with sodium dodecyl sulfate (nrCE-SDS) analysis. The results suggest that the reaction between NEM and lysine residues in the protein, as well as the decrease in electrophoretic mobility due to increased molecular weight, are the root causes for the formation of the artifact peak.

Summary: The current study investigates the colloidal behavior of nanoemulsions at different oil volume fractions and reveals the transition of nanoemulsions from liquid-like to viscoelastic gels at a volume fraction of 30%. Additionally, two regimes of colloidal interactions are proposed in the semidilute and concentrated regimes based on rheological results and pairwise interactions estimated between droplets.

Summary: Understanding the role of arsenic binding proteins is crucial in studying the mutagenicity, carcinogenicity, and teratogenicity of arsenic. Utilizing various techniques, researchers were able to identify 32 different arsenic binding proteins in HepG2 cells, which are involved in structural functions, enzymes related to metabolic cycles and transcriptional regulation. The discovery of specific proteins like poly [ADP-ribose] polymerase 1 and general transcription factor IIH subunit 1 binding with arsenicals sheds light on their potential impact on nucleotide excision repair in HepG2 cells.

Summary: This study measured the second critical micelle concentration (SCMC) of non-ionic surfactants, such as Tween and Span series, in an aqueous medium using the conductometric technique for the first time. The SCMC is a point where monodisperse equilibrium disks aggregate to form flat ribbons (cylindrical micelles) with polydisperse length, uniform width, and swollen ends. The structure of cylindrical micelles was determined via transmission electron microscopy, and important thermodynamic properties were measured. The SCMC was found to have a significant influence on these thermodynamic properties.

Summary: Proteinuria, an important sign of kidney diseases, can be differentiated using immunochemical detection or urinary proteins electrophoresis. The study aims to use SDS-PAGE with commercially available 4-20% gradient gels to detect and differentiate proteinuria. The results showed distinct protein patterns associated with glomerular and tubular proteinuria, and these patterns were related to different clinical characteristics. The SDS-PAGE separation is a reliable technique to diagnose proteinuria and differentiate its types.

Summary: This study investigates the oil washing mechanism of hydrophobically associating polyacrylamide (HAHPAM) in chemical flooding by analyzing its extensional rheology. The results show that HAHPAM solution has better extensibility compared to partially hydrolyzed polyacrylamide (HPAM), especially at high temperature and salinity. Factors such as concentration, temperature, NaCl, and surfactant affect the filament breakup time and extensional viscosity of HAHPAM solution.

Summary: This study evaluates the impact of beta-casomorphins on human health, but the results are inconclusive and limited, requiring more experiments to confirm. Since these peptides are usually further cleaved in the gut, some individuals may experience increased intestinal permeability leading to a leaky gut condition, making the absorption of beta-casomorphins possible.

Summary: The study investigated the effects of heating, addition of calcium-chelating agents, sonication, and freezing on the creaming of bovine milk. Heating had a slight impact on the creaming rate, while the addition of trisodium citrate enhanced the creaming rate. Sonication and high-temperature heating resulted in the flocculation of fat globules in the cream region.

Summary: This study evaluated the suitability of milk protein concentrate (MPC 80), skim milk powder, acid whey protein concentrate (aWPC 35), cheese whey protein concentrate and isolate (cWPC 35 and cWPI) in infant formula applications. The serum-phase compounds in casein-rich streams, especially aWPC 35, played a crucial role in controlling whey protein thermal aggregation. Replacing cWPC 35 with cWPI improved protein stability at UHT temperatures, indicating that removal of minerals from whey protein streams could increase thermal stability.

Summary: The study aimed to investigate the impact of actinidin on the functionality of milk protein systems. The results showed that the extent of hydrolysis was associated with changes in protein functionality, with solubility increasing and emulsifying properties decreasing with higher degrees of hydrolysis. Heat stability improved for whey protein concentrate while foaming properties improved for both whey protein concentrate and milk protein concentrate. Further adjustments in hydrolysis parameters and processing conditions could potentially manipulate the functionality of hydrolysates obtained using actinidin.

Summary: Temperature-mediated preservation techniques provide a simple and effective method for long-term storage of food products. However, the effects of sub-zero temperatures and freezing on the properties of heterogeneous systems like cheese are not well understood. Ice crystallization during freezing can cause undesirable changes in texture and functionality of cheese, but the findings vary due to experimental conditions. Different types of cheese may have different effects and suitability for frozen storage, with most cases adversely affecting texture and functional attributes.

Summary: This article examines the impact of amino acid mutations on the peptide structure of bovine milk protein, which can affect its processability and physiological properties. Genetic polymorphisms of bovine caseins have been found to influence the chemical, structural, and technological properties of milk. The differences between A1 and A2 genetic variants of beta-casein have gained attention recently and have prompted new developments in the field. The review provides insights into the subtle variations in physicochemical properties of bovine milk, which can support the development of dairy products with different functional properties.
