Mass spectrometric imaging of localization of fat molecules in water-in-oil emulsions containing semi-solid fat.

Firstly, we report the localization analysis of the lipid components of a water-in-oil (W/O) semi-solid emulsion by mass spectrometry imaging (MSI). Uniform emulsion droplets were prepared using microchannel emulsification devices with lecithin, stearic acid-binding monoglyceride (St-MAG), and polyglycerol polyricinoleate (PGPR) as emulsifiers. The mass image gives us the localization of phosphatidylcholine (PC) in lecithin, St-MAG, tripalmitin (PPP), medium-chain triglyceride (MCT), and high-melting-point triglyceride tristearin (C18-TAG).

Age-Related Alterations in Blood Biochemical Characterization of Hepatorenal Function in the PCK Rat: A Model of Polycystic Kidney Disease.

PCK rats develop age-related polycystic kidney disease (PKD) and liver disease and have been used to investigate pharmacotherapies to ameliorate hepatorenal lesions for patients with PKD. The PCK rat may be useful to understand the possible susceptibility to hepatotoxicity observed in the patient with PKD having hepatic polycystic lesions. Therefore, the purpose of this study was to investigate the background blood biochemical changes that reflect the hepatorenal function of PCK rats as well as the terminal histopathology in order to determine whether this model would be suitable for extrapolating the susceptibility of hepatotoxicity in patients.

Monogalactosyldiacylglycerol synthesis in the outer envelope membrane of chloroplasts is required for enhanced growth under sucrose supplementation.

Plant galactolipid synthesis on the outer envelope membranes of chloroplasts is an important biosynthetic pathway for sustained growth under conditions of phosphate (Pi) depletion. During Pi starvation, the amount of digalactosyldiacylglycerol (DGDG) is increased to substitute for the phospholipids that are degraded for supplying Pi. An increase in DGDG concentration depends on an adequate supply of monogalactosyldiacylglycerol (MGDG), which is a substrate for DGDG synthesis and is synthesized by a type-B MGDG synthase, MGD3.

Acute and subchronic toxicity and genotoxicity of SE5-OH, an equol-rich product produced by Lactococcus garvieae.

The consumption of soy-based products is associated with a number of health benefits and much of these benefits are proposed to be due to the soy isoflavones daidzein, genistein, glycitein, their glycosides, and equol, an isoflavone naturally produced from daidzein. Equol is a naturally bacterially-derived metabolite of daidzein and is produced by bacteria in the gut of those humans capable of hosting the particular organism. To allow all humans to enjoy the health benefits of equol, a new functional food ingredient has been developed that relies on bacterial conversion of daidzein to equol under strictly controlled conditions.
