[Dissection of cerebral arteries as a cause of ischemic stroke].

Dissection of cerebral arteries is a rare cause of stroke in the general population. The article describes 5 clinical cases of patients with ischemic stroke after dissection, discusses the issues of etiology, diagnosis and treatment tactics. The possibility of using high-tech methods of treatment for this subtype of stroke is emphasized.

Spin reorientation transition in CoFeB/MgO/CoFeB tunnel junction enabled by ultrafast laser-induced suppression of perpendicular magnetic anisotropy.

Magnetic tunnel junction (MTJ) is a leading contender for next generation high-density nonvolatile memory technology. Fast and efficient switching of MTJs between different resistance states is a challenging problem, which can be tackled by using an unconventional stimulus-a femtosecond laser pulse. Herein, we report an experimental study of the laser-induced magnetization dynamics in a CoFeB/MgO/CoFeB (CoFeB/MgO/CoFeB) MTJ with ultrathin CoFeB electrodes possessing perpendicular magnetic anisotropy (PMA).

[Surgical management of traumatic retroperitoneal hemor-rhage].

Aim: To present the algorithm of management of victims using modern technologies including CT, laparoscopy, angiography, intraabdominal pressure monitoring, etc.

Material And Methods: Treatment of 395 victims with traumatic retroperitoneal hemorrhage was analyzed.

Results: It was shown that the use of developed algorithm decreases mortality rate from 10.

[Diagnostics and treatment of the ischemic and reperfusion disorders by the intraabdominal ischemic syndrome].

Ethiology, pathogenesis, treatment and prevention of reperfusion disorders in emergency abdominal surgery are highlighted in the article. The thorough analysis of reperfusional disorders' pathogenesis by the abdominal compartment syndrome was carried out.

[Monitoring of intraabdominal pressure in colonic obstruction].

Results of surgical treatment of 197 patients with acute colonic obstruction complicated by intraabdominal hypertension were analyzed. Monitoring of intraabdominal pressure was made in 101 patients at the pre- and postoperative periods. Compensated, sub- and decompensated forms of obstruction depending on the data of intraabdominal pressure were determined.

[A possible association of fatal pneumonia with mutations of pandemic influenza A/H1N1 sw1 virus in the receptor-binding site of the HA1 subunit].

The paper gives the results of sequence analysis of 150 positive samples in real-time RT-PCR, including 47 autopsy materials from patients (including 10 pregnant women), who died from fatal pneumonia mainly in November-December 2009, in whom the lifetime etiological diagnosis had not been made and hence no early etiotropic therapy performed. 70% of the primary materials from the deceased patients were found to have pandemic influenza A(H1N1) v mutants in the lung tissue with D222G (15%), D222N (15%), D222E (2%) substitutions, as well as a mixture of mutants (38%). Nasopharyngeal lavages from 3 Chukotka deceased patients exhibited only consensus (nonmutant) D222 virus variants; there was a mixture of consensus and mutant virus variants in the trachea and a mixture of mutant ones in the lung.

[Fermentation of a high-protein plant biomass by introduction of lactic acid bacteria].

Lactic acid bacteria displaying increased ability to produce lactic acid, medium proteolytic activity, and tolerance to osmotic stress were isolated under selective conditions from phyllosphere and rhizosphere of registered and raised cultivars of legumes. Lactic fermentation of poorly ensilable leguminous plants (red clover and Caucasian goat's rue) was performed by introduction of rifampin-resistant homofermenting representatives of the genus Lactobacillus (selected according to a set of technologically important characteristics). The results demonstrate that introduction of active local strains of lactobacteria, as well as the collection strain Lactobacillus plantarum BS 933, enhances activation of ensiling and increases the quality of fodder, as assessed according to the standard criteria (a decrease in pH of the medium, the ratio of lactic acid to fatty acid homologues, and the composition of silage microflora).

Metallic-type oscillatory interlayer exchange coupling across an epitaxial FeSi spacer.

We study interlayer exchange coupling in epitaxial Fe/Fe(0.56)Si(0.44)/Fe trilayers.

[Study of the transcapillary exchange of water and protein on the basis of their arteriovenous difference].

The transcapillary water and protein balance was estimated by means of assessing globin and protein levels in arterial and venous blood samples. The propulsion wave and protein from blood to tissues followed by their reverse transition from tissues to be detected in dog limbs. The water outflow from blood to tissues under enhanced venous was accompanied by no reliable protein outflow.

[Shunt method of determining vascular resistance].

A method is suggested for determining vascular resistance from the blood flow in the test vascular bed and in the shunt tube that is invariable in length and diameter, paralleled to this bed. In conformity with Hagen-Poiselles's equations, the viscosity component dependent on the composition and the temperature of blood should be omitted in the results obtained by the formula (Formula: see text) where Rv -- vascular resistance; Qs and Qv -- blood flow in the shunt tube and in the vascular bed; Rs -- resistance of the shunt tube calculated according to Poiselle's formula from the shunt parameters and the viscosity index equal to 1 centipoise. At the same time the viscous-rheological component of the resistance closely related to the anatomic functional properties of the vascular network should not be replaced.
