[Embryogenesis of the Japanese quail in hypomagnetic conditions applied to deep space flights].

During future interplanetary flights and on the lunar base, astronauts and bioregenerative systems on the space ship will occur in an interplanetary magnetic field, which is much lower than the habitual geomagnetic field (GMF). It is known that hypomagnetic conditions have an adverse biological effect on human beings and other living systems. In our research the Japanese quail has been chosen as one of the possible elements of the bioregenerative live support system.

[On one term (translation of SAR) in the dosimetry of radiofrequency electromagnetic fields].

Uncertainties in the use of some terms in the dosimetry of radiofrequency electromagnetic fields are discussed. We have come to the conclusion that the term conventionally applied in the Russian literature to describe the absorbed energy is an incorrect translation of the international term "Specific Absorption Rate" (SAR). The main error in the Russian term is that the energy rather than the rate is absorbed.

[Influence of simulated hypomagnetic environment in a far space flight on the rhythmic structure of rat's behavior].

Behavior of a group of rats was observed visually and tape recorded continuously from day 19 till the end of 25-d hypomagnetic experiments. Results were statistically processed with the help of Statistica 6.0, time series spectral analysis, and cosinor analysis.

The ALTEA/ALTEINO projects: studying functional effects of microgravity and cosmic radiation.

The ALTEA project investigates the risks of functional brain damage induced by particle radiation in space. A modular facility (the ALTEA facility) is being implemented and will be operated in the International Space Station (ISS) to record electrophysiological and behavioral descriptors of brain function and to monitor their time dynamics and correlation with particles and space environment. The focus of the program will be on abnormal visual perceptions (often reported as "light flashes" by astronauts) and the impact on retinal and brain visual structures of particle in microgravity conditions.

[Effects of high energy charged particles on conduction of nerve rhythmic excitation].

The effects of heavy charged particles--alpha-particles and deuterons accelerated by cyclotron to the energies of 30.3 and 15.4 MeV accordingly--on nerve's excitability (amplitude of an action potential (AP) and speed of AP propogation has been studied.

[Assessment of the contribution of broadband quasi-continuous electromagnetic background to dose loading].

Assessment of probable dose loading due to a broadband quasi-continuous electromagnetic background is presented. A level of the quasi-continuous background in the appropriate frequency intervals could exceed maximum permissible exposure by a factor of several tens. For safety monitoring, it is suggested to use the equipment that allows registering of EMF amplitude and frequency in a wide frequency range, with sensitivity by order of magnitude greater than MPE.

[Some magnetic-biological problems of distant and long-term space flights].

Some magnetobiological problems of orbital (in the geomagnetic field--GMF) and interplanetary (in hypomagnetic conditions) flights are considered. The influence of electromagnetic fields (EMF) created by systems and equipment of the space vehicle (SV) are touched also. A level of the geomagnetic field (GMF) onboard during the orbital flights is discussed.

ALTEA: anomalous long term effects in astronauts. A probe on the influence of cosmic radiation and microgravity on the central nervous system during long flights.

The ALTEA project participates to the quest for increasing the safety of manned space flights. It addresses the problems related to possible functional damage to neural cells and circuits due to particle radiation in space environment. Specifically it aims at studying the functionality of the astronauts' Central Nervous Systems (CNS) during long space flights and relating it to the peculiar environments in space, with a particular focus on the particle flux impinging in the head.

The ALTEA facility on the International Space Station.

The ALTEA project studies the problems related to possible functional damage to the Central Nervous System (CNS) due to particle radiation in space environment. The project is a large international and multi-disciplinary collaboration. The ALTEA instrumentation is an helmet-shaped multi-sensor device that will measure concurrently the dynamics of the functional status of the visual system and the passage of each particle through the brain within a pre-determined energy window.

[Synchronization of the frequency of cardiovascular fatalities with physical time cues].

Investigations were carried out to correlate the frequency of cardiovascular catastrophes (daily mortality rate of patients with ischemic heart disease), heliogeomagnetic activity (solar radiation in the wave band 10.7 cm, H, D and Z components of the geomagnetic field), synchronization and desynchronization of circaseptidian rhythms, and total number of cardiovascular catastrophes in different seasons. The raw data sets were treated with due account of the discrete pattern of random sequences and noise in the medical data set, finite analysis interval and informativity of the derivatives of the parameters used.
