Effects of heat treatment (100 °C) at different moisture content (13-70 %) on the structural, gelation and digestive properties of starch in real mung bean flour (MBF) systems are investigated. The results showed that the structural destruction of the starch, the starch-lipid complexion and starch-protein interaction were promoted with increasing moisture content. The starch-protein interaction was mainly driven by hydrophobic interaction forces, leading the increase of total phase transition enthalpy.

A kind of yolk-free mayonnaise (YFM) with preferable quality was prepared by insoluble soy peptide aggregates (ISPA) in present work. The basic properties, rheology, texture, sensory quality, and stability for YFM with different concentration of ISPA were explored. As ISPA concentration increased from 1.

In this work, a highly stable food-grade Pickering emulsion gels was successfully prepared by hydrophobically modified insoluble soybean peptide aggregates. The relationships between the surface properties of insoluble soybean peptide aggregates and Pickering emulsion gels characteristics were clarified. After modification, the insoluble soybean peptide aggregates with high surface hydrophobicity had small particle size (377 nm), near-neutral wettability (θ = 92°) and strong interfacial adsorption capability.

Insoluble soybean fiber with few proteins, which is extracted from defatted okara by homogeneous combined with alkali treatment, was used to prepare concentrated emulsions. Firstly, insoluble soybean fiber extracted under pH12 was used to fabricate concentrated emulsions containing various particle concentrations and oil volume fractions and the optimized condition was obtained. Subsequently, insoluble soybean fiber extracted under pH12 followed by different homogeneous strengths were utilized.

Background: The role of protein-polysaccharide interactions and their mixtures has been a vital factor affecting the formation and stability of food emulsions. Okara protein (OP), which is extracted from the by-product of soybean processing, has received much attention because of its abundant sources and potential attributes with respect to food formulation. Carboxymethyl cellulose (CMC), a well-known food-grade polysaccharide additive, has been widely utilized in the protein-polysaccharide system, whereas, among the proteins, the role of OP has not yet been explored.

Objective: This study aimed to explore clinical and virological characteristics of chronic hepatitis B (CHB) patients with hepatic steatosis in order to provide a theoretical basis for the prevention and control of hepatic steatosis.

Methods: A total of 360 CHB inpatients were recruited from Affiliated Dongnan Hospital of Xiamen University and divided into hepatic steatosis group and non-hepatic steatosis group. The body mass index (BMI), waist-to-hip ratio (WHR), fasting blood glucose (FBG), triglyceride (TG), total cholesterol (TC), aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transpeptidase (GGT), hepatitis B e antigen (HBeAg), hepatitis B virus DNA (HBV DNA) and hepatic histological changes were detected and compared between the two groups.

Objective: To investigate the expression of RUNX3 mRNA and protein in hepatic cell carcinoma (HCC) and surrounding normal tissue, to analyze the relationship between RUNX3 expression and clinical pathological parameters.

Methods: Reverse transcription polymerase chain reaction (RT-PCR) and immunohistochemistry (IHC) were performed to detect the expression of RUNX3 mRNA and protein in HCC and surrounding normal tissue respectively, and their relationship with clinical pathological parameters were analyzed.

Results: The relative expression value of RUNX3 mRNA found in 51 cases HCC was 0.

The clinical differentiation between hereditary nonpolyposis colorectal cancer (HNPCC) and attenuated familial adenomatous polyposis (AFAP) is very difficult. The 62-yr-old proband presented with duodenal adenocarcinoma. His history of subtotal colectomy for colon cancer, the rarity of duodenal adenocarcinoma in the general population, and his family history of colon cancer made us suspect that he might have FAP.
