Abstract Background Sterols are structural and functional components of eukaryotic cell membranes. Plants produce a complex mixture sterols, among which β-sitosterol, stigmasterol, campesterol, cholesterol in some Solanaceae, the most abundant species. Many reports have shown that stigmasterol to β-sitosterol ratio changes during plant development response stresses, suggesting it may play role ...

Gonadal development in fish is a dominant physiological process that alters growth and fat metabolism, thereby affecting fillet quality. Sterile, triploid (3 N) female rainbow trout are generated by pressure-induced shock of zygotes (3NP), crossing diploid (2 N; fertile) tetraploid (4 male to produce offspring 100% the time (3NC; sterile). We have shown intercross-triploids (3NC) faster rates t...

Xanthomonas campestris pv. phaseoli OhrR belongs to a major family of multiple-cysteine-containing bacterial organic hydroperoxide sensors and transcription repressors. Site-directed mutagenesis and subsequent in vivo functional analyses revealed that changing any cysteine residue to serine did not alter the ability of OhrR to bind to the P1 ohrR-ohr promoter but drastically affected the organi...

Docosahexaenoic acid (C22:6ω3) generated in the liver from circulating α-linolenic acid (C18:3ω3) was recently proposed as the source of brain C22:6ω3 when the latter fatty acid is absent from the diet. The present study aims at exploring whether a comparable situation prevails in Types 1 and 2 diabetic rats, even when exposed to a normal diet. The fatty acid profile of liver, plasma and brain ...

Auger Electron Spectroscopy (AES) has been used to study the surface compositions of three types of nickel based chromium alloys. These alloys are IN600, IN601 and C22. AES analysis indicated the presence of chromium and oxygen on their surfaces. The formation of this chromium oxide surface layer, 3 nm thick, provides excellent corrosion resistance. For alloy C22, no molybdenum was indicated on...

BACKGROUND To screen biomarkers to differentiate early-stage colorectal cancer (CRC) from benign colorectal disease (BCD) and healthy controls. MATERIALS & METHODS Quantitative and qualitative analysis of C16:1, C18:3, C18:2, C18:1, C20:4, and C22:6 in 185 healthy controls, 55 patients with BCD, and 139 patients with CRC was performed. Comparisons of their levels in between CRC patients, BCD ...

BACKGROUND Serum free fatty acids (FFAs) are correlated with pathological status, and change in serum FFA levels may be associated with thyroid diseases. MATERIALS AND METHODS In this study, 664 serum samples from 322 healthy controls, 129 patients with benign thyroid disease (BTD), and 213 patients with thyroid cancer (TC) were collected. Chip-based direct-infusion nanoelectrospray-mass spec...
