The specificity of memory for a highly trained finger movement sequence: Change the ending, change all.

How are highly trained movement sequences represented in long-term memory? Here we show that the gains attained in the performance of a well-trained sequence of finger movements can be expressed only when the order of the movements is exactly as practiced. Ten young adults were trained to perform a given 5-element sequence of finger-to-thumb opposition movements with their left hand. Movements were analyzed using video based tracking.

[Two positions in evaluating the role of biodiversity].

The necessity is considered to use a compositional approach to the assessment of life phenomena in biosphere instead of, and in practice, in addition to, the traditional reductional approach. From this viewpoint, the construction of logics from top to bottom, from life as an independent system in the biosphere, to system elements, as it is the case in biogeochemistry and the general biological theory, will also appear to be necessary for biogeophysics, if such interdisciplinary science is destined to emerge.

[Is there a connection between biodiversity and the greenhouse effect].

It was discussed the role of biodiversity in ecosystems capacity to control CO2 in atmosphere as the main reason not only of "greenhouse effect" but "greenhouse catastrophe". The necessity to perfect the preventive measures has been defined by time factor. This time may be so little for completing the evolution theory and models of biosphere management.

[Transcranial electric stimulation therapy in the treatment of neurocirculatory asthenia].

Transcranial electric stimulation (TES), a combination of direct and pulse current totally up to 5 mA, rectangular impulses lasting 3-4 ms at a frequency of 75-80 Mz, via frontal and retromastoid electrodes was carried out for 30 minutes every other day. The treatment consisted of 7 to 10 sessions. Overall 189 patients suffering from vegetovascular dystonia were examined.

Results of an epidemiological study of the prevalence of arterial hypertension among employees of selected plants in Moscow and Plzen. A cooperative study.

The quality of medical care provided especially to patients with arterial hypertension employed in three industrial plants (ZIL Automobile Works, Moscow, Mytishchi Machine Works, and Skoda Works, Plzen, Czechoslovakia) was investigated in random samples of male and female employees aged 35-64 years. The lowest prevalence of hypertension (AH) was found in Skoda Works (26.4 +/- 1.
