Abnormal lipid metabolisms are closely associated with cancers. In this study, mass spectrometry was employed to in situ investigate the associations of membrane lipid phenotypes of six human lung cancer cell lines (i.e., A549, H1650, H1975 from adenocarcinoma, H157 and H1703 from squamous cell carcinomas, and H460 from a large cell carcinoma) with cancer cell types and finally total 230 lipids...

Knowledge of serum markers of liver decompensation would facilitate care of patients with hepatitis C virus (HCV) and human immunodeficiency virus (HIV) infections. HCV load and anti-c33c and anti-NS5 levels did not distinguish 28 HCV- and HIV-positive predecompensation patients from 28 matched control patients, whereas more patients than controls had high anti-c100(p) and low anti-c22(p). In m...

Hastelloy C22 and Inconel 600 and 601 alloys specimens were cyclically deformed. Specimens were sectioned and investigated. Results indicated that the grain structure of Hastelloy C22 revealed planar slip bands, whereas Inconel 600 and 601 showed slip bands having triangular ribbon morphology. The triangular ribbon bands were more distinct in Inconel 601 than in Inconel 600.

X-linked adrenoleukodystrophy (X-ALD) is a rare peroxisomal disorder, that is rapidly progressive, neurodegenerative, and recessive, and characteristically primary affects the central nervous system white matter and the adrenal cortex. X-ALD is diagnosed basaed on clinical, radiological, and serological parameters, including elevated plasma levels of very long chain fatty acids (VLCFA), such as...

We aimed to investigate the role of serum levels of polyunsaturated fatty acid (PUFA) in the development of colorectal cancer (CRC). Serum levels of n-3 and n-6 PUFA in 69 healthy control (Ctrl), 62 benign colorectal polys (CRP) and 100 CRC patients were detected by gas chromatograph. The adjusted odds ratio (OR) by quartiles of n-3 and n-6 PUFA were analyzed. During the process of Ctrl to CRP,...

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 ...
