Dental Tissue Density in Healthy Children Based on Radiological Data: Retrospective Analysis.

Background: Information about the range of Hounsfield values for healthy teeth tissues could become an additional tool in assessing dental health and could be used, among other data, for subsequent machine learning.

Objective: The purpose of our study was to determine dental tissue densities in Hounsfield units (HU).

Methods: The total sample included 36 healthy children (n=21, 58% girls and n=15, 42% boys) aged 10-11 years at the time of the study.

Modified generalized neo-fuzzy system with combined online fast learning in medical diagnostic task for situations of information deficit.

In the paper, we propose the modified generalized neo-fuzzy system. It is designed to solve the pattern-image recognition task by working with data that are fed to the system in the image form. The neo-fuzzy system can work with small training datasets, where classes can overlap in a features space.

Monoclonal Antibodies to PRAME Protein Slow the Development of PRAME-Expressing Tumor.

Two monoclonal antibodies recognizing non-overlapping epitopes of the PRAME protein were injected into immunocompetent mice to study their influence on the growth of subcutaneous tumor nodes. The B16F10 murine melanoma line, either expressing human PRAME protein or bearing only a vector without PRAME gene, were used as transplants. Each of the antibodies showed the ability to suppress tumor growth of a PRAME-expressing tumour, but not a tumor without PRAME.

Epitope Analysis of Murine and Chimeric Monoclonal Antibodies Recognizing the Cancer Testis Antigen PRAME.

We investigated the epitope specificity of different monoclonal antibodies recognizing the cancer testis antigen PRAME. Antibody 5D3 binds to the fragment of PRAME corresponding to 160-180 amino acid residues. Antibodies 6H8 and F11 bind to the fragment corresponding to 180-200 amino acid residues of PRAME.

Selected anthropogenic and natural radioisotopes in the Barents Sea and off the western coast of Svalbard.

The Murmansk Marine Biological Institute (MMBI) performed high-latitude expeditions to the Barents Sea during 2007-2009 where a scientist from the Radiation and Nuclear Safety Authority (STUK) participated. The aim of the expeditions was to study and map the current radiological situation throughout the Barents Sea. In the expeditions, samples of seawater, sediment and biota were collected for radioactivity studies.
