Spin labeling methods were used to study the structure and dynamic properties of dimyristoylphosphatidylcholine (DMPC) membranes as a function of temperature and the mole fraction of polar carotenoids. The results in fluid phase membranes are as follows: (1) Dihydroxycarotenoids, zeaxanthin and violaxanthin, increase order, decrease motional freedom and(More)
Spin-labeling methods were used to study the structure and dynamic properties of phosphatidylcholine (PC)-dihydroxycarotenoid membranes as a function of phospholipid alkyl chain length, alkyl chain saturation, temperature and mol fraction of carotenoids. (1) Dihydroxycarotenoids, zeaxanthin and violaxanthin increase order and decrease motional freedom of(More)
The oxygen diffusion-concentration product was determined in phosphatidylcholine (PC) bilayers from oxygen broadening of the spin label EPR spectra. The use of fatty acid spin labels makes it possible to do structural and oximetric measurements with the same sample. We find that polar carotenoids, zeaxanthin and violaxanthin, increase ordering of(More)
Steinert's myotonic dystrophy is a genetically conditioned systemic disease with symptoms related to circulatory, respiratory, muscular, endocrine and mental disturbances. Most if not all of these patients develop lens opacification as a presenting symptom and need to undergo cataract surgery. Nevertheless, selection of a type of anaesthesia can arise to a(More)
The authors present one of many myotonic dystrophies: Steinert myotonic dystrophy (Steinert disease), which is a disease occuring seldom, and causing a lot of problems during the diagnostic and treatment process. Genetic factors, results of the histopathology tests, main clinical symptoms, particularly ophtalmic manifestation are described in this article.
