Antioxidant activity of tryptic digests of hen egg yolk phosvitin.
It is indicated that PPPs could be used in foods as natural antioxidants with strong antioxidant activity. Expand
Active site-directed antibodies identify calpain II as an early-appearing and pervasive component of neurofibrillary pathology in Alzheimer's disease
Calpain II antibodies raised to different sequences within a cryptic region around the active site, which becomes exposed during protease activation, were shown immunohistochemically to bind extensively to neurofibrillary tangles, neuritic plaques, and neuropil threads in brains from individuals with AD.

Antioxidative stress activity of oligophosphopeptides derived from hen egg yolk phosvitin in Caco-2 cells.
It is suggested that oligophosphopeptides from hen egg yolk phosvitin possess novel antioxidative activity against oxidative stress in intestinal epithelial cells and that phosphorus and peptide structure seem to have a key role in the activity. Expand
Improved emulsifying properties of soy proteins by acylation with saturated fatty acids
Abstract Effects of acylation on emulsifying properties of soy proteins were investigated using a variety of saturated fatty acids. Beta conglycinin (7S), glycinin (11S), and acid-precipitatedExpand
Solubility improvement of shellfish muscle proteins by reaction with glucose and its soluble state in low-ionic-strength medium.
Myosin, actin, and paramyosin in glycosylated myofibrillar proteins were solubilized independently regardless of NaCl concentration, and the glycoslyated myosin lost its filament-forming ability and existed as a monomer in 0.1 M NaCl. Expand

The data suggest that specific amino acids exert protective effects against tissue oxidative stress in intestinal epithelial cells based on the structure, and specifically amino acids such as Val, Ile, and Leu elevated activities of GSH S-transferase (GST) and catalase. Expand
Enzymatic synthesis of novel phenol acid rutinosides using rutinase and their antiviral activity in vitro.
Rutinosylation of the phenolic acids increased their antiviral activity against FCV, with the sinapic acid rutinoside being the most effective. Expand
Loss of filament‐forming ability of myosin by non‐enzymatic glycosylation and its molecular mechanism
The inhibition of the self‐assembly of myosin molecules occurred chemically as a result of the increase in negative charge repulsion among myosIn molecules and physically as a consequence of the introduction of the glycosyl units into the surface of the rod region. Expand
Enhanced antiviral activity of soybean β-conglycinin-derived peptides by acylation with saturated fatty acids.
Peptide mixtures prepared from soybean β-conglycinin were acylated with saturated fatty acids of different chain length to improve their antiviral activity against feline calicivirus strain F9 which is a typical norovirus surrogate. Expand
Calcium‐Activated Neutral Proteinase (Calpain) System in Aging and Alzheimer's Disease a
The excessive calpain system activation suggested by these findings represents a potential molecular basis for synaptic loss and neuronal cell death in the brain in Alzheimer's disease given the known destructive actions of calpain I and its preferential neuronal and synaptic localization. Expand
