Ethylene-Insensitive Arabidopsis Mutants etr1-1 and ein2-1 Have a Decreased Freezing Tolerance.

The freezing tolerance of Arabidopsis thaliana (L.) Heynh. was studied in relation to functioning of the ethylene signaling pathway.

Crystal structure of -bis-[2-(1-benzotriazol-1-yl)acetato-κ]bis-(ethano-lamine-κ ,)copper(II).

The reaction of 2-(1-benzotriazol-1-yl)acetic acid (HBTA; CHNO) and mono-ethano-lamine (MEA; CHNO) with CuCl·2HO resulted in the formation of the title complex, [Cu(CHNO)(CHNO)] or [Cu(BTA)(MEA)]. Its asymmetric unit comprises one BTA anion coordin-ating to the Cu cation (site symmetry ) through the carboxyl O atom, and one MEA ligand chelating the metal cation by two heteroatoms (O and N). The equatorial Cu-O and Cu-N bond lengths are similar at 2.

[The efficacy of the moisture and warmed CO(2) for laparoscopic surgery].

A prospective, randomized study comparing 150 patients undergoing laparoscopic operations (110 patients undergoing laparoscopic cholesystectomy and 40 patients laparoscopic fundoplication) with standard CO2 insufflation vs those receiving warmed, humidified CO2 was performed. All patients were randomized into 2 groups - 84 receiving standard CO2 insufflation (control group) and 66 receiving warmed, humidified CO2 (main group). Main variables included patient core temperature, postoperative pain, analgesic requirements and other postoperative dates.

A new polymorph of 2-(2H-benzotriazol-2-yl)acetic acid.

A new polymorph of 2-(benzotriazol-2-yl)acetic acid, C(8)H(7)N(3)O(2), crystallizes in the space group C2/c (Z = 8). The non-planar mol-ecule has a synplanar conformation of the carb-oxy group. The crystal structure features helices parallel to the b axis sustained by O-H⋯N hydrogen bonding which are similar to those in the known polymorph [Giordano & Zagari (1978 ▶).

[Prognostic factors in the treatment of the bile duct injuries and strictures].

To describe the prognostic factors after surgical reconstruction data. were collected prospectively on 60 patients treated at the Scientific Center of Surgery named after M.Topchubashov and N5 City Hospital with major bile duct injuries and postoperative bile duct strictures between 2000 and 2009.

[Some aspects of classification and treatment strategy of iatrogenic bile duct injury].

Iatrogenic bile duct injury continues to be an important clinical problem, resulting in serious morbidity, and occasional mortality, to patients. None of the classification system is universally accepted and worldwide used as each has its own limitation. This article reviews the various classification systems of bile duct injury.

[Ability of winter wheat plants to become hardened against frost related to peculiarities of carbon dioxide exchange, biomass synthesis, and various forms of water-soluble carbohydrates].

The donor-acceptor relation (DAR) in a plant under cold exposure to frost was studied in the plants of winter wheat (Triticum aestivum L.) Mironovskaya 808 cultivar and its allocytoplasmatic hybrid containing alien cytoplasm of goat grass (Aegilops ovata L.) and grown in a water culture until phenophase, from two leaves until branching.

[Specific features of source-sink relations in alloplasmic hybrid of winter wheat with alien cytoplasm of goatgrass with emphasis on resistance to low temperature stress].

We studied the influence of alien cytoplasm of spring goatgrass Aegilops ovata L. on some physiological parameters in winter wheat (Triticum aestivum L.), Mironovskaya 808, under normal conditions and in the case of modified source-sink relations.

[Morphophysiological monitoring of winter wheat at spring in connection with problem of global climate change].

Data on morphophysiological monitoring of winter wheat (Triticum aestivum L.) cultivar Mironovskaya 808 grown in Hoagland and Arnon solution in a greenhouse and transferred to natural conditions in March-April 2004 with the mean daily temperature of 0.6 +/- 0.

[Effect of alien cytoplasm of goatgrass on biological and physiological properties of alloplasmic wheats].

Long-term studies of the cytoplasm-nucleus interactions in alloplasmic hybrids with the nucleus of Triticum aestivum functioning in the alien cytoplasm of Aegilops ovata are reviewed. The interaction of heterologous genome and cytoplasm affects the balanced mechanisms of developmental control of the parental forms. The changes are observed at all levels of both physiological and morphological processes.

[Status of the mnestic function of ischemic heart disease patients].

Mnemonic function was studied in 105 males with chronic coronary heart disease (CCHD). A reduced volume of memory and intensified inhibition of trace formation was observed in more than 75% of the patients. The degree of memory disorders depended on the form of the CHD course.

[Characteristics of the distribution of the markers of hepatitis B vir us infection among the healthy population of the Tadzhik SSR and Azerbaijan SSR].

A total of 708 healthy persons in Tajikistan and 576 healthy persons in Azerbaijan, these groups comprising persons of both sexes and different age groups, were examined by the method of double gel immunodiffusion (the gel precipitation test) and by the passive hemagglutination test for the presence of the markers of hepatitis B virus (HBV) infection (HBsAg and HBeAg) and antibodies to them. This investigation showed that, in accordance with the level of hepatitis B morbidity, HBsAg was significantly more often detected among the population in Tajikistan (7.2%) than in Azerbaijan (2.
