[Medical rehabilitation of patients with spinal muscular atrophy].

Unlabelled: Rehabilitation of patients with spinal muscular atrophy (SMA) is a long-term strategy of healthcare service of Russian Federation, which is aimed at slowing down the progression of the pathological process, maximal reduction of disability and improving patients' quality of life. The development of targeted programs of medical rehabilitation for patients with SMA, aimed at the reduction of the disease's main symptoms, is relevant.

Objective: To develop and scientifically establish therapeutic effects of complex medical rehabilitation of type II and III SMA patients.

How to Observe the Vacuum Decay in Low-Energy Heavy-Ion Collisions.

In slow collisions of two bare nuclei with the total charge larger than the critical value Z_{cr}≈173, the initially neutral vacuum can spontaneously decay into the charged vacuum and two positrons. The detection of the spontaneous emission of positrons would be direct evidence of this fundamental phenomenon. However, the spontaneously produced particles are indistinguishable from the dynamical background in the positron spectra.

[Analysis of free cholesterol levels in human serum using holotoxin A1].

Triterpene glycosides from holothurians holotoxin A1, stichoposides C and D were used for assay of blood serum free cholesterol instead of digitonin. Blood serum lipids were extracted by a mixture of acetone-ethanol (1:1). Free cholesterol was precipitated from the extract after addition of the glycosides and analyzed in reactions with acetic anhydride, acetic and sulfuric acids.

Triterpene glycosides from sea cucumber Stichopus japonicus Selenka.

Triterpenoidal oligoglycosides from the far eastern sea cucumber Stitchopus japonicus Selenka collected in the Posiet Bay, Japan Sea were investigated. The glycoside fraction was shown to consist of two main components, holotoxins A1 and B1 which have been isolated by chromatography on silica gel columns. The chemical structures of the holotoxins were elucidated on the basis of chemical and physiochemical evidence (for formula see text).
