[Primary delayed growth of the right and left atrial myxoma].

There is more than 58-year experience of surgical treatment of patients with intracardiac myxomas at the Petrovsky National Research Center of Surgery. Primary delayed growth of the right and left atrial myxoma after 21 years and 5 months was observed only in 1 (0.36%) patient.

Immobilization of LccC Laccase from Aspergillus nidulans on Hard Surfaces via Fungal Hydrophobins.

Unlabelled: Fungal hydrophobins are small amphiphilic proteins that can be used for coatings on hydrophilic and hydrophobic surfaces. Through the formation of monolayers, they change the hydrophobicity of a given surface. Especially, the class I hydrophobins are interesting for biotechnology, because their layers are stable at high temperatures and can only be removed with strong solvents.

Selective natural induction of laccases in Pleurotus sajor-caju, suitable for application at a biofuel cell cathode at neutral pH.

Laccases are multicopper oxidoreductases with broad substrate specificity and are applied in biofuel cells at the cathode to improve its oxygen reduction performance. However, the production of laccases by e.g.

Improving the performance of a biofuel cell cathode with laccase-containing culture supernatant from Pycnoporus sanguineus.

Laccases are multicopper oxidoreductases that can be used in biofuel cells to improve cathode performance by cathodic oxygen reduction. Here we present a laccase from the ligninolytic white-rot fungus Pycnoporus sanguineus that, in contrast to the Trametes versicolor laccase, can be produced in the absence of inducers in a standard culture medium. After 7days of cultivation the activity of this laccase in culture supernatant reached 2.

BRCA1 gene-related hereditary susceptibility to breast and ovarian cancer in Latvia.

Purpose: In this report, we summarise data on BRCA1 gene analysis in Latvia to characterise criteria of genetic testing for breast and ovarian cancer susceptibility.

Material/methods: Analysis by SSCP/HD, MALDI-TOF mass spectrometry or DNA sequencing was used for mutation detection. Mutations identified were confirmed by direct DNA sequencing.
