The main objective of our study has been to determine the role of deadwood in the shaping of the amount of soil organic matter fractions in mountain forest *** this purpose,a climosequence approach comprising north(N)and south(S)exposure along the altitudinal gradient(600,800,1000 and 1200 m a.s.l.)was set *** comparing the properties of decomposing deadwood and those of the soils located directly beneath the decaying wood we drew conclusions about the role of deadwood in the shaping of soil organic matter fractions and soil carbon storage in different climate *** basic properties,enzymatic activity and fractions of soil organic matter(SOM)were determined in deadwood and affected directly by the components released from decaying *** decomposed deadwood impacts soil organic matter stabilization more strongly than the less decayed deadwood and the light fraction of SOM is more sensitive to deadwood effects than the heavy fraction regardless of the location in the altitude *** in SOM mineral-associated fraction C content is more pronounced in soils under the influence of deadwood located in lower locations of warmer *** released from decaying wood stimulate the enzymatic activity of soils that are within the range of deadwood influence.

Exercise performance depends on both physiological abilities (e.g., muscle strength) and behavioral characteristics (e.g., motivati on). We tested the hypothesis that evoluti on of in creased aerobic exercise performanee can be facilitated by evolution of neuropsychological mechanisms responsible for motivation to undertake physical activity. We used a unique model system: lines of bank voles Myodes glareolus selected for high swim-induced aerobic metabolism ("aerobic" A lines). In gen eration 21, voles from the 4 A lines achieved a 57% higher /y voluntary maximum" swiminduced aerobic metabolism (V02swim) than voles from 4 unselected,"control" C lines. In C lines, V02swim was 9% lower than the maximum forced-exercise aerobic metabolism (VO2run;P= 0.007), while in A lines it was even higher than VO2run, although not significantly (4%, P=0.15). Thus, we hypothesized that selection changed both the aerobic capacity and the neuronal mechanisms behi nd motivation to un dertake activity. We investigated the influe nee of reuptake in hibitors of dopamine (DARI), serotonin (SSRI), and norepinephrine (NERI) on VOaSwim. The drugs decreased V02swim both in C and A lines (% decrease compared with saline: DARI 8%, P< 0.001;SSRI 6%, P< 0.001;NERI 8%, P< 0.001), but the proportional response differed between selection directions only for NERI (stronger effect in C lines: P= 0.008) and the difference was marginally non-significant for SSRI (P= 0.07) and DARI (P= 0.06). Thus, the results suggest that all the 3 monoamines are involved in signaling pathways controlling the motivation to be active and that norepinephrine could have played a role in the evolution of increased aerobic exercise performance in our animal model.

A new species, Dactylolabis （Eobothrophorus） hoffeinsorum sp. nov. from the Baltic amber is described, based on one male. The distinctive characters are the shape of the discal cell in the wing and the shape of the process on tergite IX. The description of Dactylolabis （Eobothrophorus） lauryni Podenas, 2003 is amended, based on an additional specimen. With the new species added herein, the number of species of this subgenus totals four. The wing venation, antennae, and tergal processes of all four species of the subgenus described from the Baltic amber are compared.

The aim of this work was to use cellulose nanocrystals that were obtained by hydrolysis in phosphoric acid solution and further modified with succinic anhydride in the microwave field for PLA reinforcement.A series of allbionanocomposites containing unmodified and surface modified cellulose nanocrystals with CNC content in the range of 1–3%_(w.t.) were obtained by melt blending and tested by XRD,SEM,DSC and DMA to investigate the effect of surface esterification of CNCs on the structure,morphology,dynamic mechanical properties of bionanocomposites,as well as phase transitions of PLA in the presence of cellulosic *** investigations showed the highest increase of storage modulus by ca.7%(335 MPa at 25℃)in the glassy state of PLA for 2%_(w.t.)of unmodified ***,addition of 2%_(w.t.)of succinylated CNCs caused the highest increase of the onset of glass transition temperature(by 6.2℃)thus widening the temperature range of biocomposite *** increase of glass transition temperature indicates the strongest interfacial interactions due to improved miscibility of surface modified nanocrystals and thus good dispersion of additive in PLA matrix providing high interface.

Esophageal duplication cysts are rare inherited lesions usually diagnosed in early childhood. Most of them are found in the mediastinum and manifest themselves as separate masses along or in continuity with the native esophagus. Their prevalence remains unknown and they are treated either surgically or endoscopically. In this report we describe a series of four adult patients in whom esophageal duplication cysts were Iocalised intramurally as masses pressing on the esophageal lumen and who were diagnosed with endoscopic ultrasonography. All patients were initially referred to other centres for upper gastroduodenoscopy due to nonspecific dyspeptic symptoms. After finding suspicious lesions in the esophagus their endoscopists referred them for endoscopic ultrasound examination at our centre. In two of the cases lesions mimicked esophageal varices and the other two submucosal tumours. In all four patients endoscopic ultrasonography has shown esophageal duplication cysts. Patients had no symptoms suggesting disease of the esophagusand required no treatment. As the true prevalence of esophageal cysts is unknown, it is very likely that in many patients, like in these four described by us, they may cause no symptoms, remain undetected and require no intervention. Increasing availability of new diagnostic modalities such as endoscopic ultrasonography may change the current view regarding the prevalence of esophageal duplication cysts and prove that they may1 in fact, not be such rare findings.

Poly(phenylene oxide)/renewable polyamide 11 (PPO/PA11 20/80) blends toughened with glycidylmethacrylate grafted ethylene-n-octene copolymer (GEOC) were prepared in a co-rotating twin-screwextruder. The reaction between GEOC and PPO/PA11 blend was analyzed by gel content tests. Themorphology of PPO/PA11/GEOC blends was observed by scanning electron microscope. The SEMresults showed that PPO formed the continuous phase, though it is a minority component of blends. Withincreasing GEOC content from 5 to 15 wt% the morphology of the blends transformed from droplet-matrix toco-continuous structure, in which both PA11 and PPO phases are continuous. The blend with co-continuousmorphology had better mechanical properties than those with droplet-matrix morphology. The impactstrength of the PPO/PA11/GEOC blends was much higher compared to the one without GEOC as well asPA11 due to the compatibilizing effect, which was also proved by DSC analysis, rheological behavior (MFR,DMTA) and tensile properties.
