    Notes: Summary Experiments showed that there are no significant changes of the motor function in the seminal cells after x-ray irradiation of frogs (20, 000 r). This shows that disturbance of oxidative phosphorylation under the action of radiation is not a general biological regularity. The effect of ionizing radiation on the resynthesis of highenergy (ATP) differs in the cells of radiosensitive and radioresistant tissues; evidently it is primarily determined by the different localization of the corresponding enzyme systems therein. There are no visible disturbances in the ability of “glycerol models” of myofibrils, the cilia of the ciliated epithelium and spermatozoa (obtained from the tissues of irradiated animals), to interact with ATP. This points to a rather low radiosensitivity of the contractile cellular proteins and explains the high radioresistance in some phases of cell division connected with the separation of the chromosomes and equatorial division of the cytoplasm.

    The action of a high pressure on the adenosinetriphatase activity of myosin (1959)
    Springer
    Bulletin of experimental biology and medicine 47 (1959), S. 690-692

    Notes: Summary Solutions of reprecipitated myosin lose completely their adenosinetriphosphates activity under the effect of high pressure (4000 atmospheres). However, they retain their ability to readily dissolve in 0.6 M KCl and to become precipitated in subsequent dialysis or after considerable dilution of myosin salt solution with water. The viscosity of myosin, free of actomyosin admixture, rises under the effect of high pressure. Myosin subjected to the effect of high pressure loses its ability to combine with an activated actin with the formation of actomyosin. The viscosity of actomyosin gels subject to high pressure (4000 atmospheres) does not diminish after addition of adenosinetriphosphates. Under the effect of high pressure there must occur some kinds of changes in the myosin structure, these being associated with inactivation of certain groups (possibly SH) and imparting to myosin an enzymatic character without, however, making it lose its hydrophilic properties.

    Notes: Summary An experimental method for producing pneumonia in rabbits is presented. A culture ofB. enteritidis gartneri was obtained from a rabbit having developed the disease spontaneously. This organism was used to reproduce the disease in 100% of the animals inoculated intratracheally.

    Notes: Summary It was established that hypophysectomy causes decreased resistance of rats to diphtheria toxin. LD50 of diphtheria toxin is less for hypophysectomized rats than for intact ones. It equals correspondingly 0.247 and 0.418. Introduction of ACTH to hypophysectomized anfmals increased their resistence to diphtheria toxin (LD50 equaied 0.303).

    Notes: Summary Proteins extracted by Weber's solution from the smooth muscle of the uterus do not possess the ability to interact with myosin preparations with the formation of actomyosin. This makes highly improbable the assumption of Snellman and Tenow on the presence of any appreciable amounts of free actin in 0.5 M KCL extracts of myometrium. Investigations conducted by the method of paper electrophoresis demonstrate the presence of 3 fractions in the myometrium extracts with high ionic potential, viz., myoalbumin, heterogeneous myogen and actomyosin. The latter consists of a small quantity of actomyosin (undoubtedly bound with nucleoproteins) and water-soluble myofibrillar proteins (mainly tropomyosin and possibly Δ-protein). Likewise these investigations give no grounds for associating the peculiarity of the myometrial proteins with the high concentration of the “easily extractable” actin in the muscles of the uterus.

    Notes: Abstract Preparations of the intermetallic compounds UAl2, UAl3 and UAl4 were obtained by high-temperature interdiffusion of aluminum and dispersed uranium, prepared by decomposing its hydride then grinding the product and heating the powder obtained. Debye x-radiographic investigation showed that the preparations obtained consisted of one phase and the parameters of their structures were close to those published earlier. The amount of hydrogen evolved during separate solution of the preparations and the starting components in a specially selected solvent (mixture of HCl, H3PO4, Na2SiF6, H2PtCl5 and CuSO4· 5H2O) Indicated that the preparations had the compositions; UAl1.997, UAl2.994 and UAl3.997. The differences in the heats of solution of these preparations and appropriate mixtures of their components gave die heats of formation (−ΔH°293)UAl2, UAl3 and UAl4, which were 22.3±2.4, 25.2±2.2 and 31.2±3.1 kcal/mole, respectively.

    Notes: Abstract The properties and fundamental methods of preparing metallic beryllium are discussed on the basis of results obtained by Soviet authors. Comparison is made between thermal reduction of beryllium fluoride by magnesium, electrolytic extraction, and purification of beryllium by distillation in vacuum. Preparation of beryllium articles by different methods of powder metallurgy, melting in vacuum induction furnaces with centrifugal casting, extrusion of beryllium articles and the structure and properties of compact beryllium are discussed. It is found that the maximum tensile strength of pure beryllium samples extruded from a metal hot∞ pressed in vacuum is about 20 kg/mm2 at 425 ° C and that at this temperature the samples possess high plasticity (over 20% elongation).
