Summary: The prevalence of kidney stone disease is increasing globally, with a high recurrence rate for urinary stones. Dietary composition plays a crucial role, and inadequate fluid intake is a major risk factor for urolithiasis. Other nutritional factors like protein, carbohydrates, oxalate, calcium, and sodium chloride also influence the risk of kidney stone formation.

Summary: Kidney stone disease is still not well understood in terms of its formation mechanism and metabolic changes. This manuscript summarizes the progress in research on metabolic changes in kidney stone disease and proposes new potential targets. The influence of metabolism of various substances on stone formation is discussed, including oxalate regulation, reactive oxygen species release, macrophage polarization, hormone levels, and other substance alteration. Understanding these metabolic changes and utilizing emerging research techniques will provide new directions in the treatment of kidney stones.

Summary: This study investigated the gene expression changes in the kidney of a rat model with kidney stones. The results showed dysregulated genes related to injury, apoptosis, immune response, solute carriers, transporters, and metabolic factors. These findings contribute to a better understanding of the pathogenesis of nephrolithiasis and could potentially lead to the development of new strategies for prevention and treatment.

Summary: This study focused on the preparation and structural characterization of calcium oxalate hydrates with the presence of gallic acid (GA). The results indicated that GA inhibited the formation of COM and promoted the formation of COD, while medium pH and the amount of added GA had a significant effect on COD formation. Electrochemical measurements were performed to investigate the interactions and possible adsorption between GA and formed crystals.

Summary: Nephrolithiasis is a multifactorial disease that results in the formation of stones in the kidneys. The most common type of stones are calcium oxalate hydrate stones, which are associated with hypercalciuria and hyperoxaluria. By analyzing the composition and crystalline structures of calcium oxalate stones, distinctions can be made between dihydrated and monohydrated phases, improving diagnosis accuracy for patients.

Summary: The study found that oxalate, COM, and urine from patients with CaOx KS induce oxidative stress-induced premature senescence (SIPS) and telomere shortening in human kidney cells, potentially contributing to the development of CaOx KS through upregulation of p16 and downregulation of shelterin components, specifically POT1.

Summary: By using time-resolved in situ atomic force microscopy (AFM), the study observed the preferential adsorption and occlusion of negatively charged phosphatidylcholine vesicles into the ((1) over bar 01) face, while only positively charged (2,3-dioleoyloxy-propyl)-trimethylammonium vesicles were occluded into the (010) face. The free energies of binding between the lipid vesicles and COM crystal faces measured by AFM-based single-molecule dynamic force spectroscopy explain the vesicle-crystal face interaction through an electrostatic attraction. These findings provide new experimental evidence for understanding the mechanism of lipid occlusion.

Summary: The study demonstrates a correlation between 24-hour urine calcium oxalate supersaturation (CaOx SS) and in vivo stone growth in individuals with pure CaOx stones. Higher CaOx SS levels were associated with increased stone growth rates, indicating potential for noninvasive study of stone growth modulators and improved stone risk prediction through CT volumetric analysis.

Summary: The prevalence and recurrence rate of kidney stones are high, and there is currently no effective treatment to prevent their occurrence. However, this study reveals that AIM can suppress stone development and improve stone-induced physical damages. AIM interacts with calcium oxalate crystals to inhibit stone formation, and also removes inflammatory molecules to reduce stone development. Furthermore, AIM improves kidney function and alleviates physical symptoms such as weight loss. These findings provide a basis for the development of comprehensive therapy for kidney stone disease.

Summary: This study aimed to determine the content of bioactive protein osteopontin (OPN) in bovine milk and developed an ELISA method to measure OPN concentration in milk from Danish Holstein cows. The study found that OPN levels in milk have a low heritability and significant individual variation, with levels increasing with days in milk and decreasing with parity.

Summary: Secreted proteins and peptides have great potential as therapeutics and enzyme catalysts due to their high stability, which is maintained by disulphide bonds. However, limited availability of synthetic biology tools and heterologous production systems hampers the discovery and applications of these proteins. In this study, the design of DisCoTune plasmids in the Escherichia coli T7 protein production system successfully enhanced the yield and activity of an industrial protease and a conotoxin, demonstrating the promising potential of this technology for biotechnological applications.

Summary: This study investigated the ability of osteopontin (OPN) to prevent the adhesion of dental biofilm-forming bacteria. OPN was found to be the most effective protein in reducing bacterial adhesion. Bioactive milk proteins show potential to delay harmful biofilm formation on teeth and hence the onset of biofilm-related oral disease.

Summary: This study aimed to assess the role of milk proteins in reducing capsaicin-induced oral burning sensation. Participants dipped their tongues in capsaicin gel and rinsed their mouth with different solutions including milk proteins. The results showed that short-term rinsing with milk proteins did not significantly alter capsaicin-induced oral burning sensation, unpleasantness, somatosensory changes, or tongue temperature compared with control.

Summary: Osteopontin (OPN) is a multifunctional protein that is expressed in various cell types and found in most tissues and physiological secretions. It plays a role in immune system regulation, biomineralization, tissue development, bacterial interactions, and more. OPN is highly concentrated in milk and is believed to have developmental and physiological effects on infants. This article reviews and compares existing knowledge on the structure, function, and health implications of milk OPN.

Summary: Osteopontin (OPN) is abundant in human milk and has a lower concentration in bovine milk. Both human and bovine milk OPN resist digestion and have beneficial effects on intestinal development. This study compared the effect of digested human and bovine milk OPN on gene expression in Caco-2 cells and found that both OPNs regulated the expression of genes related to biological processes such as the ubiquitin system, DNA binding, transcription, and transcription control pathways.

Summary: The aim of this study was to investigate the interaction between Osteopontin (OPN) and intestinal cells, as well as its transport across models of the intestinal barrier. The results showed that OPN binds to intestinal cells but is not internalized. It was also found that OPN crosses the barrier models through the transcytosis pathway, and this process is time-, temperature-, and energy-dependent.
