Infants show systematic rhythmic motor responses while listening to rhythmic speech.

Rhythm is known to play an important role in infant language acquisition, but few infant language development studies have considered that rhythm is multimodal and shows strong connections between speech and the body. Based on the observation that infants sometimes show rhythmic motor responses when listening to auditory rhythms, the present study asked whether specific rhythm cues (pitch, intensity, or duration) would systematically increase infants' spontaneous rhythmic body movement, and whether their rhythmic movements would be associated with their speech processing abilities. We used pre-existing experimental and video data of 148 German-learning 7.

[Dynamics of the radiation conditions and evaluation of the radiation dosage of the inhabitants of Kiev following the accident at the Chernobyl Atomic Electric Power Station].

The estimation of the effective dose equivalents of exposure to accidental and non-accidental sources was made on the basis of the studying of radiation situation variations in Kiev after the Chernobyl accident in 1986-1989. The total annual effective dose equivalents to the Kiev population from all sources of exposure for 1986-1989 were 9.19, 7.

[Comparative study of human erythrocyte membranes in normal people and in Huntington's chorea patients].

Erythrocytes of healthy volunteers and of patients with hereditary chorea were studied. Evaluation of the state of cellular membrane was carried out by measuring osmotic resistance, activity of Na+, K(+)-ATPase and protein composition. In the patients osmotic resistance of erythrocytes was distinctly decreased down to 66.

[Study of human erythrocyte membrane proteins by 2-dimensional electrophoresis].

Fractionation of human erythrocyte membrane proteins was performed using a modification of two-dimensional gel electrophoresis described by P. O'Farrel with isoelectric point plotted against molecular mass. All major erythrocyte proteins, including high molecular weight proteins, such as spectrin and band 3 protein, identified by one-dimensional sodium dodecyl sulfate gel electrophoresis, were visualized by silver staining of two-dimensional gels.
