We introduce novel interference cancellation schemes in order to improve the performance in the partial block multi-carrier code division multiple access (PB/MC-CDMA) environment. We are called OIC (order interference canceller). In the OIC scheme, we should find the signal which is the strongest step by step and later removed from the receiver signals to reduce the interference. The OIC is abl...

As neurons die, cholesterol is released in the central nervous system (CNS); hence, this sterol and its metabolites may represent a biomarker of neurodegeneration, including in amyotrophic lateral sclerosis (ALS), in which altered cholesterol levels have been linked to prognosis. More than 40 different sterols were quantified in serum and cerebrospinal fluid (CSF) from ALS patients and healthy ...

Five new highly oxygenated lanostane-type triterpenoids [ganoderic acid GS-1 (1), ganoderic acid GS-2 (2), ganoderic acid GS-3 (3), 20(21)-dehydrolucidenic acid N (4) and 20-hydroxylucidenic acid A (5)] were isolated from the fruiting body of Ganoderma sinense, together with known compounds including 6 triterpenoids and 3 sterols. The structures of the new triterpenoids determined by spectrosco...

Aralia chinensis var. dasyphylloides is widely distributed in China and used as a traditional herbal medicine for the treatment of digestive and immune system diseases. The present study aimed to search for novel oleanolic-type triterpenoids in low-polarity fractions. Six new triterpene derivatives (1-6), together with two known compounds were isolated from the barks of A. chinensis var. dasyph...

Gallbladder bile of the bullfrog, R a m catesbezana was found to contain a number of minor bile acids and bile alcohols in unconjugated forms. The following bile acids and bile alcohols were identified by combined gas-liquid chromatography-mass spectrometry: cholic acid, allocholic acid, 3a,7a, 12a-trihydroxy-5a-cholestan-26-oic acid, 3a,7a, 12atrihydroxy-24-methyl-5~-cholestan-26-oic acid, 3a,...

8-Aminoquinoline amides of 3-oxo-olean-12-en-28-oic acid and 3-oxo-urs-12-en-28-oic were obtained characterized by 1H, 13C-NMR single crystal X-ray analysis. The used triterpenoic acids are oxidized forms naturally occurring oleanolic ursolic acids. Such types derivatives known for their anticancer antiviral activities. On the other hand, 8-aminoquinoline frequently transition metal complexatio...
