The biotransformation of lithocholic acid by Pseudomonas sp. strain NCIB 10590 under anaerobic conditions was studied. The major products were identified as androsta-1,4-diene-3,17-dione and 3-oxochol-4-ene-24-oic acid. The minor products included 17beta-hydroxyandrost-4-ene-3-one, 17beta-hydroxyandrosta-1,4-diene-3-one, 3-oxo-5beta-cholan-24-oic acid, 3-oxochola-1,4-diene-24-oic acid, 3-oxopre...
Opioid-induced constipation (OIC), a prevalent and distressing side effect of opioid therapy, does not reliably respond to treatment with conventional laxatives. OIC can be a treatment-limiting adverse event. Recent advances in medications with peripherally acting μ-opioid receptor antagonists, such as methylnaltrexone, naloxegol, and alvimopan, hold promise for treating OIC and thus extending ...
The biocatalyzed conversion of hyocholic acid (3α,6α,7α-trihydroxy-5β-cholan-24-oic acid) into ω-muricholic (3α,6α,7β-trihydroxy-5β-cholan-24-oic has been obtained exploiting a small library 7α- and 7β-HSDHs (hydroxysteroid dehydrogenases). process optimized performed avoiding the isolation 7-oxo intermediate using appropriate coupled enzymes for in situ cofactor regeneration. Moreover, reducti...
Our ongoing investigations on the stem bark of Uncaria macrophylla afforded a new ursolic triterpene, 3β,6β,19α-trihydroxy-urs-12-en-28-oic acid-24-carboxylic acid methyl ester (1), named uncariursanic acid, and three known ursolic triterpenes including 3β,6β,19α-trihydroxy-23-oxo-urs-12-en-28-oic acid (2), 3β,6β,19α-trihydroxy-urs-12-en-28-oic acid (3) and ursolic acid (4). Their structures we...
Bile salts of the coelacanth, Latimeria chalumnae, Smith, have been analyzed and shown to have three bile alcohols, latimerol, 5 alpha-cyprinol, and 5 alpha-cholestane-3 beta, 7 alpha,-12 alpha,25,26-pentol, two C24 bile acids, chenodeoxycholic acid and cholic acid, one C26 bile acid, probably 3 beta, 7 alpha, 12 alpha-trihydroxy-27-nor-5 alpha-cholestan-26-oic acid, and two C27 bile acids, 3 a...
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...
The clerodane diterpenoids trans-kolavenolic acid, 18-oxocleroda-3,13(E)-dien-15-oic acid, ent-(18-hydroxycarbonyl)-cleroda-3,13(E)-dien-15-oate, 2-oxo-ent-cleroda-3,13(Z)-dien-15-oic acid and trans-2-oxo-ent-cleroda-13(Z)-en-15-oic acid, and the chlorobenzenoid O-(3-hydroxy-4-hydroxycarbonyl-5-pentylphenyl)-3-chloro-4-methoxy-6-pentyl-2-oxybenzoic acid were isolated from Tessmannia martiniana ...
مطالعة حاضر بهدنبال تحلیل عوامل مؤثر بر تجارت درون صنعتی ایران با کشورهای طرف تجاری در بلوکهای منطقهای EU،D8 ، OIC، ECO، GCC و ASEAN به صورت متقابل و به تفکیک بخشهای کشاورزی، صنعت و خدمات با استفاده از دادههای تلفیقی دوره 1980-2009 مبتنی بر رویکرد مدلهای تابلویی پویا و بهکارگیری روش گشتاورهای تعمیمیافته است. برای توضیح تجارت درون صنعتی بین ایران و کشورهای طرف تجاری، متغیرهای اندازة اقتصا...
این مقاله بهدنبال تحلیل عوامل مؤثر بر تجارت درون صنعتی ایران با کشورهای طرف تجاری در بلوکهای منطقهای اسلامی D8، ECO، GCC و OIC به صورت متقابل و به تفکیک بخشهای کشاورزی، صنعت و خدمات با استفاده از دادههای تلفیقی دوره 1980−2009 مبتنی بر رویکرد مدلهای تابلویی پویا و بهکارگیری روش گشتاورهای تعمیمیافته است. برای توضیح تجارت درون صنعتی بین ایران و کشورهای طرف تجاری، متغیرهای اندازۀ اقتصادی، د...
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 ...
