DarkSky Halos: Use-Based Exploration of Dark Matter Formation Data in a Hybrid Immersive Virtual Environment.

Hybrid virtual reality environments allow analysts to choose how much of the screen real estate they want to use for Virtual Reality (VR) immersion, and how much they want to use for displaying different types of 2D data. We present the use-based design and evaluation of an immersive visual analytics application for cosmological data that uses such a 2D/3D hybrid environment. The applications is a first-in-kind immersive instantiation of the Activity-Centered-Design theoretical paradigm, as well as a first documented immersive instantiation of a details-first paradigm based on scientific workflow theory.

The evaluation of metallothionein expression in nasal polyps with respect to immune cell presence and activity.

Background: The expression of metallothionein (MT) is involved in acquiring resistance to immune-mediated apoptosis; it is also a negative regulator of the immune response. Nasal polyps are typified by a resistance to immune-mediated apoptosis as well as by excessive immune cell infiltration. RCAS1 (receptor-binding cancer antigen expressed on SiSo cells) is a membrane protein capable of inducing the apoptosis of CTLs and NK cells.

The antioxidative role of selenium in pathogenesis of cancer of the female reproductive system.

Selenium, as a component of few antioxidant enzymes, participates indirectly in elimination of reactive oxygen species and in antioxidative defense of the organism. There is a correlation between the concentration of selenium, activity of glutathione peroxidases (GSH-Px), and other parameters of antioxidative defense in blood components. The above mentioned factors were suggested to play an important role in etiopathogenesis of neoplastic diseases.

[Reactive oxygen species as an inducing factor of neoplasms of female reproductive organs ].

Aim: In our study we measured selenium concentration in the blood of women with diagnosed cancer and benign tumors. The results were compared with healthy women. Some other parameters of the antioxidant system in all studied groups were also investigated, namely, activity of glutatione peroxidase, superoxide dismutase, as well as the levels of glutathione and malondialdehyde.
