The comparative pharmacokinetics of free doxorubicin and doxorubicin entrapped in cardiolipin liposomes was evaluated in rats at a dose of 6 mg/kg i.v. Doxorubicin was entrapped in cardiolipin liposomes by using 11.2 mumol of drug, 5.6 mumol of cardiolipin, 28.5 mumol of phosphatidylcholine, 19.5 mumol of cholesterol, and 11.1 mumol of stearylamine. The peak plasma concentration with free doxor...

Normal pregnancy corresponds to a procoagulant state. Acute myocardial infarction during pregnancy is rare, yet considering the low non-pregnant risk score of childbearing women it is still surprisingly frequent. We report a case of postpartum recurrent non-ST elevation myocardial infarction in a 40-year-old caucasian woman with essential thrombocythaemia in the presence of a positive JAK-2 mut...

The significance of the relationship between the three components of cardiolipin complementfixation antigen, viz. cardiolipin, natural lecithin, and cholesterol, was first studied by Maltaner and Maltaner (1945) in experiments with syphilitic pooled rabbit or human sera. Suitable sensitivity with regard to the routine sero-diagnosis of syphilis was obtained with the antigen formula: Cardiolipin...

An analysis of the turnover of the major phospholipids of Micrococcus cerificans growing or nongrowing cultures. The turnover rates of (14)C-PE and (14)C-PE were 61.5% of the total phospholipid, exhibited no significant rate of turnover in either growing or nongrowing cultures. The turnover rates of PE-(14)C and PE-(32)P were 3.2% per hr and 1.2% per hr, respectively. Phosphatidylglycerol (PG) ...

Using an ultrasonicate of the Reiter treponeme as antigen the Reiter haemagglutination test (RHA) was evaluated as a serological test for syphilis. Comparison of the results of the cardiolipin Wassermann reaction, Reiter protein complement-fixation test, the fluorescent treponemal antibody-absorbed (FTA-ABS) test, the Treponema pallidum haemagglutination test (TPHA) (at dilutions of 1/16 and 1/...

F(1)F(0) ATP synthase forms dimers that tend to assemble into large supramolecular structures. We show that the presence of cardiolipin is critical for the degree of oligomerization and the degree of order in these ATP synthase assemblies. This conclusion was drawn from the statistical analysis of cryoelectron tomograms of cristae vesicles isolated from Drosophila flight-muscle mitochondria, wh...

31P-NMR shows that poly(L-lysine) binding to cardiolipin, phosphatidylserine or phosphatidylglycerol does not affect the macroscopic structure or local order (in the phosphate region) of the phospholipids. In the case of cardiolipin poly(L-lysine) inhibits the ability of Ca2+ to induce the hexagonal HII phase. Alternatively, poly(L-lysine) induces the hexagonal HII phase for a fraction of the p...

We reported previously that three basic amino acids (Arg-360, Arg-364 and Lys-372) of DnaA protein are essential for its functional interaction with cardiolipin. In this study, we examined the effect of mutation of some basic amino acids in a potential amphipathic helix (from Lys-327 to Ile-345) of DnaA protein on this interaction. ATP binding to the mutant DnaA protein, in which Arg-328, Arg-3...

Antimicrobial resistance to traditional antibiotics is a crucial challenge of medical research. Oligonucleotide therapeutics, such as antisense or Transcription Factor Decoys (TFDs), have the potential to circumvent current resistance mechanisms by acting on novel targets. However, their full translation into clinical application requires efficient delivery strategies and fundamental comprehens...

OBJECTIVE To investigate the presence of IgG and IgM types of anticardiolipin (aCL) and antiphospholipid (aPL) antibodies in younger Iranian patients with ischemic stroke. METHODS Both IgG and IgM types of aPL (cardiolipin, anti phosphatidyl inositol, anti phosphatidyl serine, anti phosphatidic acid and beta 2-glycoprotein I [B2-GPI]) and aCL alone (cardiolipin and B2-GPI) were measured in 11...
