[Effects of hybrid comprehensive cardiac telerehabilitation conducted under the pension prevention program of the Social Insurance Institution].

Background: The Polish Social Insurance Institution (SII), under its pension prevention initiative, has taken measures to support the patients return to work and thus developed a new model of hybrid, comprehensive, cardiac telerehabilitation (HCCT). The aim of the study was to analyze the effects of HCCT in terms of its acceptance, adherence to and influence on patients' physical capacity and ability to return to work.

Material And Methods: The study included 99 patients, aged 54.

Solvatochromic effects in the electronic absorption and nuclear magnetic resonance spectra of hypericin in organic solvents and in lipid bilayers.

The natural product hypericin was tested in recent years as a biological photosensitizer with a potential for viral and cellular photodamage. We thus studied extensively its spectroscopy and membrane partitioning. Absorption, fluorescence excitation and emission spectra of the sodium salt (HyNa) were measured in 36 protic and aprotic, polar and apolar, solvents.

Liposome binding constants and singlet oxygen quantum yields of hypericin, tetrahydroxy helianthrone and their derivatives: studies in organic solutions and in liposomes.

The spectroscopy and photophysics of several hypericin and helianthrone derivatives were studied in methanol and when bound to liposomes. The singlet oxygen quantum yields (phi(delta)) were measured indirectly relative to Rose Bengal and hematoporphyrin IX, employing 9,10-dimethylanthracene as a singlet oxygen trap. Hypericin was found to have a phi(delta) of 0.

New flow cytometric technologies for the 21st century.

The envelope that defines the limits within which flow cytometry was developed is being rapidly expanded. For example: detection sensitivity has been extended to single molecules, the size range of "particle" analysis now extends from DNA fragments to plankton (1,000.+ microns), cell and chromosome sorting rates are being increased dramatically by using inactivation procedures (50,000 per second versus 2,000 per second), rapid kinetic flow cytometry enables real-time analysis of molecular assembly and cell function in the sub-second time domain, the lifetime of a fluorochrome bound to a single cell can be measured with nsec precision, and classical karyotype information (cell to cell heterogeneity) can be determined in a flow based system.
