Tricomplex Fixation of Phospholipids
A basis for the interpretation of the structure of the cell membrane is often looked for in electron microscope investigations on the structure of lipid models. A difficulty in these investigations is our lack of knowledge of the effect of the preparative treatment on the structure studied. This applies especially to the strongly oxidizing fixatives: osmium tetroxide and potassium permanganate....
متن کاملVariational Tricomplex, Global Symmetries and Conservation Laws of Gauge Systems
Using the concept of variational tricomplex endowed with a presymplectic structure, we formulate the general notion of symmetry. We show that each generalized symmetry of a gauge system gives rise to a sequence of conservation laws that are represented by onshell closed forms of various degrees. This extends the usual Noether’s correspondence between global symmetries and conservation laws to t...
متن کاملClinical Results of Percutaneous Fixation of Pelvic and Acetabular Fractures: A Minimally Invasive Internal Fixation Technique
Background: The pelvic ring fractures (PRF) and acetabular fractures (AF) are among the major orthopedic injuriesassociated with high rates of morbidity and mortality. Open surgical stabilization is the standard treatment for themajority of these complications. Percutaneous minimally invasive surgical stabilization of the fractures has become anaccepted treatment method for th...
متن کاملHplc Separation of Phospholipids
The principles involved in the selection of solvents and the use of counter ions, together with the choice of column, for the separation of phospholipids by highperformance liquid chromatography (HPLC) are described.
متن کاملPhospholipids of Streptococcus faecalis.
Autoradiograms of total lipid extracts from Streptococcus faecalis ATCC 9790, harvested in the stationary phase from a medium containing (32)P-orthophosphate, showed six major spots. The corresponding compounds were identified as diphosphatidylglycerol (possibly with a penta acyl structure); phosphatidylglycerol; a provisionally identified mixture of alanylphosphatidylglycerol and of the 2'-lys...
