It is associated with an underlying tumor in about 50% of reported cases. Antibodies directed against the GIuN1 subunit of the NMDA receptor are responsible for the disease pathogenesis and their detection in the patient's serum and cerebrospinal fluid are required to make a definite diagnosis. Classical clinical presentation consists of flu-like symptoms, followed by psychiatric disturbances and impaired consciousness, epileptic seizures and movement disorders. During the past decade, it has become an emerging area of research and discussion as more than 1,000 cases have been reported since the first description of this specific disease entity in 2007. Despite a rather typical clinical course it is frequently diagnosed and treated with a delay up to many months. Overall prognosis tends to be favorable. However, it strongly depends on early diagnosis and rapid treatment initiation. While diagnostic criteria for probable and definite anti-NMDAR encephalitis have been proposed, there are no evidence based guidelines for specific treatment strategies. Glucocorticoids, plasma exchange and IVIG are generally used as 1 st line treatment, in patients who do not respond, 2nd line treatment with Cyclophosphamide or Rituximab is used. We report a case of a confirmed non-paraneoplastic anti-NMDAR encephalitis with a rather classical manifestation in a Latvian woman who is first hospitalized in a psychiatric clinic then transferred to an ICU (intensive care unit), treated with glucocorticoids, plasma exchange and later Cyclophosphamide with a good outcome.展开更多

Symbiotic nitrogen fixation by actinomycetes associated with alder species has been widely used for improvement of soil properties of abandoned agricultural lands, but relatively little is known of the interactions of these processes with soil type and chemical composition. We conducted a space-for time study with soil sampling under and outside grey alder tree canopies on two different soil groups to explore effects of colonisation of former agricultural lands by alder on soil properties.Results: The results were analysed using analysis of variance. During the first 25 years after afforestation of former agricultural lands there was a significant increase in content of Ctot, Ntot, K+, Fe3+, Mn2+and available P in the topsoil(0–10 cm and 11–20 cm) of Dystric Arenosols soils, which are deficient in organic matter. Such trends were not evident in organic matter rich Endostagnic Umbrisols soils, in which exchangeable K+concentration decreased and exchangeable Fe3+and Al3+concentration increased.Conclusions: The results show that the effects of grey alder on soil chemical properties depend on initial soil properties. The invasion of agricultural land by grey alder leads to spatial variability of soil chemical properties creating a mosaic pattern.展开更多

The present experimental studies are directed to investigation of dyeing the linen fabric prepared with modification with enzymes. In the research, 1% and 2% solution of cellulase enzyme Beizym ENC-SB (garment auxiliary of enzymes mixture of CHT R. BEITLICH GmbH/BEZEMA AG) and pectinase Beisol PRO (enzymes mixture for cleaning cellulose fibers of CHT R. BE1TLICH GmbH) enzyme solutions were used. The main objective of this work is focus on results studies of enzyme influence on dyeing of flax fabric with direct Solphenyl dye triade Blue FGLE (economical, fairly good light fast blue, main trichromatic component for medium shades with high wash fastness), Scarlet BNLE (economical scarlet, main trichromatic component for medium to dark shades) 200%, and Yellow GLE (very bright neutral yellow, main trichromatic component for high wash fastness requirements). The dye-bath exhaustion, color fastness to rubbing and washing were estimated. The color parameters before and after tests were calculated.展开更多

This heated air can be exploited for drying of agricultural products, room ventilation and room heating etc. 0.1 × 0.5 × 1.0 meter long FPC (fiat-plate collector) with a sun following platform was built. Air velocity at the experiments was v = 0.9 m/s. Collectors of insulated and un-insulated surfaces with steel-tinplate absorber as a covering material warmed the ambient air up to 10-12 and 5-6 degrees correspondingly (at irradiance 800 W/m^2). This difference indicates the great importance of insulating the collector body. It can be explained with intense heat exchange between the absorber and ambient air which reduces the efficiency of the collector. There was good correlation with irradiance and the air heating degree. The investigations showed that more effective FPC had the collector with absorber tinplate in the middle of the collector body. At favorable weather conditions the heating degree of the ambient air at the outlet reaches 6-8 degrees more that at the outlet of the insulated collector covered by steel-tinplate.展开更多

The G-TiO<sub>2</sub> nanocomposite was synthesized using sol-gel technique, and its structural & morphological properties were studied using scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM), particle analyzer and UV-Visible spectroscopy (UV-Vis) measurement techniques. Various petroleum-based chemicals (toluene, naphthalene and diesel) were remediated, and samples were analyzed using optical and gas chromatography (GC) techniques. The mechanism of photocatalytic remediation of petroleum compounds using G-TiO<sub>2</sub> nanomaterials is understood and well compared with data available in literature.展开更多

The present manuscript displays the advantage of organic remediation in both UV and visible radiation using graphene (G) doped TiO2 nanoparticles, G doped ZnO nanowires. The nanostructured G-TiO2 nanoparticles and G-ZnO nanowires were synthesized using sol-gel and hydrothermal methods. The nanostructured materials were characterized using scanning electron microscopy (SEM) and X-Ray diffraction (XRD), procedures. The remediation of organic compounds (naphthalene, methyl orange) in water was achieved under both UV and visible radiation using graphene doped nanostructured photocatalytic materials. The advantage of graphene doped ZnO nanowires as well as G-TiO2 nanoparticles has revealed organics remediation in both UV and visible radiation of light.展开更多

The knowledge of nutrition management and its relation with pest and diseases are basis for setting up a high yield production system. Most of the pest and disease control procedures used by farmers can be considered as soil fertility management and these nutrition practices can have impact on the physiological susceptibility of crop plants to pest and diseases by affecting the plant resistance. Silicon content of plants is particularly effective against pest and diseases in rice and certain rice genotypes are more efficient accumulators of silicon, thus making them more resistant. In the absence of natural heritable resistance in rice varieties, resistance could be induced by altemate strategies to suppress certain pest and pathogens. Hence experiments were carried out in two stages during kharif 2010 and 2011 to assess the concentration of silicon in the index leaves of rice plant utilizing 133 varieties in four locations. The silica content of promising varieties ranged from 1.50% to 3.20%, 1.60% to 3.15%, 1.49% to 3.20% and 1.55% to 3.06% with a mean values of 2.50%, 2.48%, 2.51% and 2.43% at Jagtial, Warangal, Rajendranagar and Rudrur centres of Telangana region and not much variation in mean silica content in index leaves at different places. The overall yield from four locations ranged from 2,653 kg/ha to 6,860 kg/ha with a mean of 5,624 kg/ha. The yields recorded at Jagtial, Warangal, Rajendranagar and Rudrur centres ranged from 2,886 to 7,198, 2,653 to 6,831, 2,653 to 6,860 and 4,399 to 5,950 kg/ha, respectively. The lowest mean yield 5,069 kg/ha was noticed at Rudrur and the highest yield 5,940 kg/ha was found at Warangal. The variations in yields might be due to genotypic variations and also due to variations in climatic conditions of different locations.展开更多
