The first basic boundary value problem of Riemann's type for bianalytical functions in a plane with slots

The paper is devoted to the investigation of one of the basic boundary value problems of Riemann's type for bianalytical functions. In the course of work there was made out a constructive method for solution of the problem given in a plane with slots. There was also found out that the solution of the problem under consideration consists of consequent solutions of two Riemann's boundary value problems for analytical functions in a plane with slots.

DYNAMICS OF BIOCHEMICAL INDICES OF BLOOD SERUM IN RABBITS UNDER THE INFLUENCE OF PHOTOTHERAPY AFTER LOCAL SKIN THERMAL BURN

The article presents data on the dynamics of some biochemical indices in blood serum of rabbits (total protein, alanine aminotransferase, ureal, creatinine, total cholesterol, glucose) during phototherapy of local skin thermal injury using "Bioprone", "Rikta", "Azor", OKN-11M, BOP-4 devices in 5-15 days after wounding. Obtained data testifies to the development of the response of an organism in the form of metabolic processes aimed at the maintenance of constant internal environment but expressed less that at vast burns. Course of phototherapy quite effectively but without distinct differentiation by the method of therapy has positive effect on the normalization of biochemical indices of blood serum

Comparative morphological evaluation of the effectiveness of some practices of light therapy in wound healing (experimental testing)

The article provides information on the efficiency of thermal injury healing in animals (rabbits) under light therapy with «Bioptron», «Ricta», «Azor», 0KN-11M, BOP-4. An analysis has been done of the results of the morphological and planimetric research within 5-15 days after wounding. The factual data received have led to the conclusion that it is advisable to combine different physiotherapeutic practices in wound treatment. Synchronization of processes of an epitelization and maturing of granulyatsionny fabric allowed to recommend for appointment different lengths of waves of optical range in a certain sequence, beginning from ultra-violet beams of short, average range, then laser radiation of an infrared, red range, and also their combination, then to continue influence by the polarized light through standard periods (courses)

Contribution of Various Carbon Sources Toward Isoprene Biosynthesis in Poplar Leaves Mediated by Altered Atmospheric CO2 Concentrations

Biogenically released isoprene plays important roles in both tropospheric photochemistry and plant metabolism. We performed a 13CO2-labeling study using proton-transfer-reaction mass spectrometry (PTR-MS) to examine the kinetics of recently assimilated photosynthate into isoprene emitted from poplar (Populus × canescens) trees grown and measured at different atmospheric CO2 concentrations. This is the first study to explicitly consider the effects of altered atmospheric CO2 concentration on carbon partitioning to isoprene biosynthesis. We studied changes in the proportion of labeled carbon as a function of time in two mass fragments, M41+, which represents, in part, substrate derived from pyruvate, and M69+, which represents the whole unlabeled isoprene molecule. We observed a trend of slower 13C incorporation into isoprene carbon derived from pyruvate, consistent with the previously hypothesized origin of chloroplastic pyruvate from cytosolic phosphenolpyruvate (PEP). Trees grown under sub-ambient CO2 (190 ppmv) had rates of isoprene emission and rates of labeling of M41+ and M69+ that were nearly twice those observed in trees grown under elevated CO2 (590 ppmv). However, they also demonstrated the lowest proportion of completely labeled isoprene molecules. These results suggest that under reduced atmospheric CO2 availability, more carbon from stored/older carbon sources is involved in isoprene biosynthesis, and this carbon most likely enters the isoprene biosynthesis pathway through the pyruvate substrate. We offer direct evidence that extra-chloroplastic rather than chloroplastic carbon sources are mobilized to increase the availability of pyruvate required to up-regulate the isoprene biosynthesis pathway when trees are grown under sub-ambient CO2

Aim: to study complications of preoperative chemoembolization of the gastroduodenal artery and external beam radiation therapy in patients with pancreatic head cancer.Material and Methods. Sixty patients underwent chemoembolization of the gastroduodenal artery and external beam radiation therapy. Femoral artery angiography was performed using the Seldinger’s technique. Lipiodol 5–7 ml and gemcitabine 400 mg/m2 were used for transarterial chemoembolization. Radiation therapy was given at a total dose of 50 Gy (2 Gy/fraction, 5 times a week, over 5 weeks) using AGAT -R apparatus.Results. Complications after chemoembolization of the gastroduodenal artery were observed in 18.3 % of patients: abdominal pain in 3.3 % of patients; pain and nausea in 3.3 %; pain, nausea and fever in 6.7 %; pain, nausea and increased blood amylase in 1.7 %; pain, nausea and fever, blood amylase in 1.7 %; nausea, fever and blood amylase in 1.7 %. Radiation-induced injuries were observed in 23.3 % of patients: erythema in 18.3 %, grade 1 leukopenia in 1.7% and grade 2 leukopenia in 3.3 %.Conclusion. Complications of neoadjuvant therapy in terms of frequency and severity were consistent with literature data, were manageable with conservative treatment, and did not increase the duration of the preoperative period.Цель исследования – изучить частоту осложнений предоперационного этапа (химиоэмболизация желудочно-двенадцатиперстнокишечной артерии и дистанционная лучевая терапия) комбинированного лечения больных раком головки поджелудочной железы.Материал и методы.

Biogenic Volatile Organic Compound and Respiratory CO2 Emissions after 13C-Labeling: Online Tracing of C Translocation Dynamics in Poplar Plants

Globally plants are the primary sink of atmospheric CO(2), but are also the major contributor of a large spectrum of atmospheric reactive hydrocarbons such as terpenes (e.g. isoprene) and other biogenic volatile organic compounds (BVOC). The prediction of plant carbon (C) uptake and atmospheric oxidation capacity are crucial to define the trajectory and consequences of global environmental changes. To achieve this, the biosynthesis of BVOC and the dynamics of C allocation and translocation in both plants and ecosystems are important.We combined tunable diode laser absorption spectrometry (TDLAS) and proton transfer reaction mass spectrometry (PTR-MS) for studying isoprene biosynthesis and following C fluxes within grey poplar (Populus x canescens) saplings. This was achieved by feeding either (13)CO(2) to leaves or (13)C-glucose to shoots via xylem uptake. The translocation of (13)CO(2) from the source to other plant parts could be traced by (13)C-labeled isoprene and respiratory (13)CO(2) emission.In intact plants, assimilated (13)CO(2) was rapidly translocated via the phloem to the roots within 1 hour, with an average phloem transport velocity of 20.3±2.5 cm h(-1). (13)C label was stored in the roots and partially reallocated to the plants' apical part one day after labeling, particularly in the absence of photosynthesis. The daily C loss as BVOC ranged between 1.6% in mature leaves and 7.0% in young leaves. Non-isoprene BVOC accounted under light conditions for half of the BVOC C loss in young leaves and one-third in mature leaves. The C loss as isoprene originated mainly (76-78%) from recently fixed CO(2), to a minor extent from xylem-transported sugars (7-11%) and from photosynthetic intermediates with slower turnover rates (8-11%).We quantified the plants' C loss as respiratory CO(2) and BVOC emissions, allowing in tandem with metabolic analysis to deepen our understanding of ecosystem C flux
