Superfluid density in the underdoped YBa2Cu3O7-x: evidence for d-density-wave order of the pseudogap.

The investigation of the penetration depth lambda(ab)(T,p) in YBa2Cu3O7-x crystals allowed one to observe the following features of the superfluid density n(s)(T,p) proportional, variant lambda(-2)(ab)(T,p) as a function of temperature T0) depends on p slightly in the optimally and moderately doped regions (0.

[The choice of suture material in forming bile-diverting anastomoses].

In the experiment, it was established that the use of a synthetic thread of the noncapillary type with a small diameter, when microsurgical technique was employed, provided minimal damage, full-value adaptation of the membranes of the organs sutured, thus facilitating primary healing of anastomosis.

[The frequency parameters of electrogastromyograms].

The changes in the frequency parameters of the basic electrical gastric rhythm were studied with the application of cutaneous electrodes in men. The study has demonstrated that the frequency parameters of the basic electrical gastric rhythm are dependent on the organ's functional state. The frequency parameters can be used for the identification of the gastric functional state both in healthy and sick subjects.

[Primary and recurrent retroperitoneal neoplasms of non-organic origin].

Having analyzed results of the treatment of 216 patients the authors came to a conclusion that recurrencies of tumors, repeat ones included, can not be considered as contraindications for operations. The most favourable results were obtained in the operative treatment of recurrent lymphosarcomas.
