Raman dissipative solitons generator near 1.3 mkm: limiting factors and further perspectives.

Raman dissipative solitons (RDS) have been investigated numerically. It was found that the area of stable generation is bounded in terms of pump spectral bandwidth and pulse energy. Existing optimum is strongly affected by the net cavity dispersion. The spectral bandwidth of the generated RDS linearly depends on its energy and reaches more than 50 nm in the 5-meters long cavity. Developed numerical model reproduces all the effects observed experimentally. It predicts ability to generate high-quality pulses with energy up to 6 nJ compressible down to ∼100 fs duration. The work shows that RDS generation technique can produce high-energy ultrashort pulses at wavelengths not covered by typical active mediums.

Eighty-eight patients operated on for coronary heart disease were examined. Continuous irrigation of pericardial cavity with circulating cold solution in combination with antegrade cardioplegia was used in 53 patients, antegrade cardioplegia with external cooling of the heart by icy mass in the rest 35. Intensive external cooling provided a stable temperature of the myocardium during clamping of the aorta.

[First experience in normo-thermal artificial circulation with constant warm blood cardioplegia]. / Pervyi opyt normotermicheskogo iskusstvennogo krovoobrashcheniia s postoiannoi teplovoi krovianoi kardioplegiei.

Normo-thermal artificial circulation (NAC) with constant thermal blood cardioplegia (CTBC) was carried out for the first time in Russia in 12 coronary patients subjected to surgical revascularization of the myocardium. Artificial circulation device with the vesical type oxygenator was used for NAC. For CTBC, systems for delivery of the cardioplegic solution and blood from the oxygenator in 1:4 ratio were used. Freme type cardioplegic solutions made by the authors were used. NAC duration was 53 to 139 min, the mean value being 103.4 min. The aorta was clamped for 38 to 96 min, the mean value 70.1 min. Asystole developed soon after CTBC began. After CTBC was discontinued, heart work recovered without cardiotonics.

[The modulation of postural asymmetry in recipient animals under the influence of the cerebrospinal fluid from patients with manic-depressive psychosis]. / Moduliatsiia poznoi asimmetrii u zhivotnykh-retsipientov pod vliianiem tserebrospinal'noi zhidkosti bol'nykh maniakal'no-depressivnym psikhozom.

Suboccipital administration of cerebrospinal fluid of patients with affective disorders elicits a pose asymmetry in rats-recipients; the character of the pose asymmetry depends on the phase of donor's disease: cerebrospinal fluid of manic patients elicits a relative flexion of the right posterior limb, of depressive patients--a relative flexion of the left posterior limb. High-molecular and low-molecular fractions of the cerebrospinal fluid were active, trypsin treatment led to disappearance of the effect. The results suggest a significant role of protein components of the cerebrospinal fluid in the organization of the symptom of functional asymmetry of the central nervous system under affective disorders.
