Since ancient times, mulberry leaves ( Morus spp.) have been used to rear the silkworm Bombyx mori . Because grows well on leaves, toxicities and defensive activities of these against herbivorous insects overlooked. Here we show that are highly toxic caterpillars other than B. , because ingredients latex, a milky sap exuded from leaf veins. The toxicity was lost when latex eliminated artificial diets containing showed toxicity. Mulberry contained very high concentrations alkaloidal...
The green rice leafhopper, Nephotettix cincticeps, is a vascular bundle feeder that discharges watery and gelling saliva during the feeding process. To understand potential functions of for successful safe on host plants, we analyzed complexity proteinaceous components in N. cincticeps. Salivary proteins were collected from sucrose diet adult leafhoppers had fed through membrane stretched parafilm. Protein concentrates separated using SDS-PAGE under reducing non-reducing conditions. Six...

Insoluble elastin was rendered soluble by pepsin digestion and HCl treatment. The antioxidative activity of pepsin-solubilized (PSE) acid-solubilized (ASE) investigated. peroxide value carbonyl oleic acid in the presence absence PSE ASE after oxidation at high temperature (75−90 °C) were evaluated. Both effective inhibitors acid. enhanced citric as a synergist. are thought to be valuable antioxidants. Since preparation easier than PSE, could therefore more useful an agent. low molecular...
To reduce the immunogenicity of β-lactoglobulin (β-LG), two β-LG−carboxymethyl dextran (CMD) conjugates (Conj. 40 and Conj. 162) were prepared by using water-soluble carbodiimide (EDC). The molar ratios β-LG to CMD in 162 8:1 7:1, respectively. Each conjugate maintained ∼50% retinol binding activity β-LG. Structural analyses intrinsic fluorescence, CD spectra, ELISA with monoclonal antibodies indicated that surface each was covered without great disruption native conformation. By conjugation...
Bovine β-lactoglobulin−alginic acid oligosaccharide (β-LG−ALGO) conjugate was prepared by the Maillard reaction to improve function of β-LG. The molar ratio β-LG ALGO in conjugates 1:7. isoelectric point 4.55, which is lower than that Fluorescence studies suggested conformation around Trp had changed and surface covered with saccharide chain. Structural analyses monoclonal antibodies indicated Val15−Ile29 (β-sheet) changed, while native structure maintained Thr125−Lys135 (α-helix). By...
The preventive effects of glycomacropeptide (GMP) against intestinal infection were investigated, and conjugates GMP with xylooligosaccharide (XOS) carboxymethyldextran (CMD) prepared by the Maillard reaction to enhance effect GMP. binding ability pathogenic bacteria was evaluated a assay biotinylated bacteria. showed bind Salmonella enteritidis enterohemorrhagic Escherichia coli O157:H7 (EHEC O157). This decreased sialidase treatment completely eliminated periodate oxidation. These results...
Abstract The silicate layers of montmorillonite clay were pillared with SiO2–TiO2 sol particles. Although only the SiO2 sols negatively charged, mixed oxide positively charged and could be ion-exchanged interlayer cations montmorillonite. resulting clays had a basal spacing expanded to more than 40 Å; was maintained during calcination up 773 K. adsorption properties calcined samples studied for nitrogen as well organic vapors. A structural model arrangement intercalated particles is proposed...
Bovine β-lactoglobulin (β-LG) was conjugated with the acidic oligosaccharides, alginic acid oligosaccharide (ALGO) and phosphoryl oligosaccharides (POs) by Maillard reaction to reduce immunogenicity of β-LG. The molar ratios β-LG ALGO POs in conjugates were 1:6 1:8. carbohydrate-binding sites β-LG−ALGO conjugate partially identified be 60Lys, 77Lys, 100Lys, 138Lys, 141Lys. isoelectric point each lower than that CD spectra indicated secondary structure almost maintained after conjugation....
<i>Background:</i> Since allergen-specific IgE is directly involved in the type I allergic reaction, development of a method for inhibiting Th2 responses which lead to induction production would be useful approach preventing disorders. The ability and mechanism alginic acid oligosaccharide (ALGO), an obtained from natural edible polysaccharide, suppressing was examined detail. <i>Methods:</i> Lymph node cells β-lactoglobulin (β-LG)-primed BALB/c mice were cultured...
A simple artificial diet was prepared to facilitate the mass-rearing of Mamestra brassicae and Mythimna separata at a low cost. The composed herbivorous animal food (ZC®), wheat germ, dried yeast, ascorbic acid, soybean oil, agar, water, propionic acid. In both species, development, viability fecundity individuals appeared be approximately same with this as compared previous ones. To date, 7 consecutive generations species have been reared on diet.
The green rice leafhopper (GRH), Nephotettix cincticeps, is one of the most important pests in temperate Asian countries. GRH, a vascular feeder, secretes watery and gelling saliva process feeding on phloem xylem sap. It known that GRH contains several bioactive proteins, including enzymes such as laccase beta-glucosidase. In this study, we performed transcriptome analysis salivary glands using Illumina paired-end sequencing. Of 51,788 assembled contigs, 16,017 (30.9%) showed significant...
Abstract Individuals with prodromal symptoms of Lewy body disease (LBD), such as rapid eye movement sleep behavior disorder (RBD), often showed imaging defects similar to patients Parkinson’s and dementia bodies. We examined dopamine transporter (DaT) single-photon-emission computed tomography (SPECT) metaiodobenzylguanidine (MIBG) scintigraphy in 69 high-risk subjects ≥2 (dysautonomia, hyposmia, probable RBD) 32 low-risk without symptoms, whom were identified through a questionnaire survey...
