Heat capacity signature of frustrated trimerons in magnetite.

Recently it has been proposed that the long-range electronic order formed by trimerons in magnetite should be frustrated due to the great degeneracy of arrangements linking trimerons. This result has important consequences as charge ordering from the condensed minority band electrons leads to a complex 3D antiferro orbital order pattern. Further more, the corner sharing tetrahedra structure of spinel B-sites supports frustration for antiferromagnetic alignments.

[The efficacy of fiber bronchoscopy under outpatient polyclinic conditions].

Basing on the experience of conducting 795 bronchofibroscopies under conditions of polyclinic authors discuss organized and methodological aspects ensuring maximal study safety permitting to avoid serious, danger for life complications. Pathologic changes of tracheobronchial tree were exposed in 64.6% cases, 46.

[Dynamics of calmodulin in cerebral structures under the action of modulated UHF electromagnetic fields].

The influence of modulated UHF-electromagnetic fields (low intensity) on calmodulin levels in several brain structures was studied. It was shown that UHF-electromagnetic fields influence calmodulin levels in the hypothalamus and sensorimotor cortex. Its effect depends on modulation regimes.

[New adenosine derivatives as agents to prevent postischemic disorders].

The authors studied prophylactic action of adenosine analogs during ischemic liver damage. Hepatoprotective action of adenosine analogs was established.
