Acyclic, standard tetraether and diether lipids each account for about 50% of the total ether lipids found in Methanospirillum hungatei. Sixteen ether lipids were purified and defined according to relative weight percentage and staining reactions on thin-layer plates. Structures were elucidated for six previously uncharacterized tetraether lipids. Four of(More)
Cells of Methanococcus jannaschii, grown at 65 degrees C in a defined medium, contained 7% of lipid composed of 87% polar and 13% neutral components. Within the polar fraction 16 lipids were resolved by thin-layer chromatography, 4 of which were present in trace amounts. Staining reactions demonstrated that the more abundant lipids were glycolipids,(More)
Smoking still represents a huge public health problem. Millions of children suffer the detrimental effects of passive smoking. An increasing number of countries have recently issued laws to regulate smoking in public places. Instead, homes remain a site where children are dangerously exposed to environmental tobacco smoke (ETS). The combination of tobacco(More)
The lipids of a moderately halophilic methanogen, Methanococcus voltae, accounted for 5.1% of the cell dry weight and consisted of 91% polar lipids and 9% neutral lipids. Twelve polar lipids were detected, three of which, all derivatives of 2,3-di-O-phytanyl-sn-glycerol, were identified as: 2,3-di-O-phytanyl-1-O-[beta-D-glucopyranosyl-(1-6)-beta-D-(More)
CCNU and methotrexate were employed as salvage treatment in 34 small cell lung cancer patients resistant to CAV/PE alternating induction chemotherapy. In the 33 evaluable patients we observed an objective response rate of 21.2% and 3% complete response; median survival was 4 months with 2 patients alive 18 months from starting salvages chemotherapy. The(More)
OBJECTIVE To retrospectively assess the results of surgical treatment in a consecutive series of 110 patients with Stage IIb and IIIa non small cell lung cancer (NSCLC) invading chest wall. METHODS A series of 110 patients underwent surgery for Stage IIb and IIIa NSCLC with involvement of chest wall. There were 101 male and 9 female patients, mean age was(More)
Incubation of microsomes from 25 degrees C- or 10 degrees C-grown cells of Candida lipolytica with [14C]oleoyl-CoA ( [14C]18:1-CoA) in the presence or absence of NADH resulted in rapid acyl transfer of [14C]18:1 to phospholipids (mainly phosphatidylcholine (PC) and phosphatidylethanolamine (PE) and to acylglycerols. Incorporation into PC was greatly(More)
Microsomal membranes prepared from Candida lipolytica cells grown at 10 degrees C had a higher lipid content and degree of unsaturation than membranes prepared from cells grown at 25 degrees C. The specific activities of stearoyl-CoA (18:0-CoA), oleoyl-CoA (18:1-CoA), and dioleoyl phosphatidylcholine (18:1-PC) desaturases in microsomes of cells grown at(More)
Structures were determined for two phospholipids and three glycolipids purified from chloroform-methanol extracts of Methanothrix concilii GP6. Together they accounted for 14% of the total lipid and were based on a C20,20-diether core structure consisting of either 2,3-di-O-phytanyl-sn-glycerol or its 3'-hydroxy analog, namely,(More)
PURPOSE Platinum-based chemotherapy currently represents standard treatment for advanced non-small-cell lung cancer. Gemcitabine is one of the most interesting agents currently in use in advanced non-small-cell lung cancer, and high response rates have been reported when it is administered in combination with cisplatin. The aim of the present study was to(More)
