Article Abstract
This case-control study aimed to assess the association of dairy-derived digestion-resistant bioactive peptides (BPs) with the risk of prostate cancer (PCa) in a cohort of 50 men with PCa and 99 controls. Dietary, demographic, and anthropometric factors of all participants were assessed. Various types of dairy-derived BPs were determined by an method. High intake of total digestion-resistant BPs, low molecular weight peptides, high molecular weight peptides, phosphorylated residues, disulfide bonds, and antioxidant peptides was not significantly associated with the risk of PCa in the adjusted models (>0.05), while low-fat [odds ratio (OR): 0.19, 95% confidence intervals (CI): 0.05－0.66] and total dairy intake (OR: 0.23, 95% CI: 0.06－0.79) were inversely associated with PCa risk. To the best of our knowledge, this study is the first to report an association between dairy-derived BPs and the risk of PCa and an inverse association with consumption of dairy products in Iranian men likely due to the low intake of this population. Notably, the BP content of dairy products was not significantly associated with PCa risk.

Radiation exposure initiates a cascade of reactions, including the release of reactive oxygen species, DNA double-strand breaks, and cellular apoptosis, leading to cell death, tissue damage, and potentially the development of cancer. Consequently, there is an urgent need to develop highly effective and low-toxicity radioprotective agents. Traditional chemically synthesized protective agents face significant limitations in clinical applicability due to their pronounced off-target toxicity, narrow therapeutic window, and high production costs.

Globally, new antibiotic development lags behind the rapid evolution of antibiotic-resistant bacteria. Given the extensive research and development cycles, high costs, and risks associated with new pharmaceuticals, exploring alternatives to conventional antibiotics and enhancing their efficacy and safety is a promising strategy for addressing challenges in the post-antibiotic era. Previous studies have shown that antimicrobial peptides/peptidomimetics (AMPs) primarily use a membrane-disruption mechanism distinct from conventional antibiotics to exert bactericidal effects.

Peptide quantitative structure-activity relationship (pQSAR) has been widely used in the computational peptidology community to model, predict and explain the activity and function of bioactive peptides. Various amino acid descriptors (AADs) have been developed to characterize the residue building blocks of peptides at sequence level. However, a significant issue is that the total number of AAD-characterized descriptors is proportional to peptide length, thus causing inconsistency in the resulting descriptor vector matrix for a panel of length-varying peptide sequences (LVPSs), which cannot be engaged in pQSAR modelling.

Sheep milk has gained increasing attention for its compositional similarity to human milk and its abundance of bioactive compounds with nutritional and therapeutic potential. It is rich in proteins, essential fatty acids, vitamins, minerals, immunoglobulins, and hormones, as well as peptides and oligosaccharides with antiviral, antibacterial, anti-inflammatory, and immune-modulatory effects. Despite these benefits, the literature remains fragmented, with limited integration of data on the mechanisms by which these components influence health outcomes, and few comprehensive comparisons with other mammalian milks.

Cardiovascular disorders remain a leading cause of death worldwide, and the use of contemporary stents is paving the way for a profound shift in the field of cardiology. In the surgical process postimplantation, the graft or stent and host-immune interaction play a significant role in the healing process, thus it is a major challenge in healthcare. To address these challenges, recent advancements have introduced bioactive coatings with specialized modifications in stents to enhance their interaction with surrounding environment.
