3283   EPR Studies of DOPA–Melanin Complexes with Netilmicin and Cu(II) at Temperatures in the Range of 105–300 K EPR Studies of DOPA–Melanin Complexes with Netilmicin and Cu(II) at Temperatures in the Range of 105–300 K Magdalena Zdybel, Barbara Pilawa, Ewa Buszman, Dorota Wrześniok, Ryszard Krzyminiewski;Zdzisław Kruc    0 The application of electron paramagnetic resonance (EPR) spectroscopy in pharmacy of melanin complexes with netilmicin and Cu(II) was presented. The continuous microwave saturation of EPR spectra of DOPA–melanin and the complexes was performed. EPR spectra were measured on an X-band (9.3 GHz) spectrometer at temperatures in the range of 105–300 K. Paramagnetic copper ions decrease the intensity of the EPR lines of melanin’s free radica... 查看全文

3284   Triptolide triggers the apoptosis of pancreatic cancer cells via the downregulation of Decoy receptor 3 expression Triptolide triggers the apoptosis of pancreatic cancer cells via the downregulation of Decoy receptor 3 expression Wei Wang, Xinfeng Li, Weimin Sun, Lurong Zhang, Mei Zhang, Benzu Hong;Guorong Lv    0 Purpose  Triptolide (TPL) is a diterpenoid triepoxide that effectively induces apoptosis in a wide variety of cancer cells. However, the detailed mechanism by which TPL activates caspase cascade remains elusive. This study aimed to examine the antitumor effects of TPL against pancreatic cancer and investigate the underlying mechanism. 查看全文

3285   Development of a bioprocess to convert PET derived terephthalic acid and biodiesel derived glycerol to medium chain length polyhydroxyalkanoate Development of a bioprocess to convert PET derived terephthalic acid and biodiesel derived glycerol to medium chain length polyhydroxyalkanoate Shane T. Kenny, Jasmina Nikodinovic Runic, Walter Kaminsky, Trevor Woods, Ramesh P. Babu;Kevin E. O’    0 Sodium terephthalate (TA) produced from a PET pyrolysis product and waste glycerol (WG) from biodiesel manufacture were supplied to Pseudomonas putida GO16 in a fed-batch bioreactor. Six feeding strategies were employed by altering the sequence of TA and WG feeding. P. putida GO16 reached 8.70 g/l cell dry weight (CDW) and 2.61 g/l PHA in 48 h when grown on TA alone. When TA and WG were supplied in combination, biomass productivity (g/l/h) was increased betwe... 查看全文

3286   Electrochemical performances of two kinds of ternary electrolyte mixtures with lithium bis(oxalate)borate Electrochemical performances of two kinds of ternary electrolyte mixtures with lithium bis(oxalate)borate S. Y. Li, X. L. Cui, X. L. Xu, X. M. Shi;G. X. Li    2012 Conductivities (κ) of PC (propylene carbonate)/EMC (ethyl methyl carbon ate)/DMC (dimethyl carbonate) and EC (ethylene carbonate)/EMC/DMC solutions of lithium bis(oxalate)borate (LiBOB) were experimentally determined at a temperature (θ) range from −40.0 to 60.0°C. Under such experimental conditions, the effect factors on the κ, such as the salt molar concentrations (m), and the volume ratio of solvent compositions, were also investigated. The results ... 查看全文

3287   Impact of some factors on the maximum module of water runoff in mountain rivers of the Caucasus Impact of some factors on the maximum module of water runoff in mountain rivers of the Caucasus A. P. Kazankin    2012 The factors influencing the water runoff formation, such as vegetation, litter, soil, and rock are analyzed. The initiation of floods on forest soils underlain by dense, fissured, and disintegrated rocks as well as the impact of karst on the water runoff under the condition of subalpine meadows are discussed. A relationship between the maximum water runoff in rivers of the Caucasus and the percentage of forest land and watershed areas is proposed. Some data on ch... 查看全文

3288   Slope flows governed by diffusion effects in seas, lakes, and reservoirs Slope flows governed by diffusion effects in seas, lakes, and reservoirs V. N. Zyryanov;L. E. Lapina    2012 The hydrodynamics of slope flows governed by heat and salt diffusion near a rigid sloping impermeable boundary in stratified water bodies is studied. The physics of this phenomenon consists in that, because of the impermeability of the shore slope, the fluxes of heat and salt normal to the slope surface must be zero. Since the background stratification does not meet this condition, diffusion boundary layers appear along the shore slope. It is shown that, dependin... 查看全文

3289   Mesoporous Silica Composites Containing Multiple Regions with Distinct Pore Size and Complex Pore Organization Mesoporous Silica Composites Containing Multiple Regions with Distinct Pore Size and Complex Pore Organization Anthony Y. Ku, Seth T. Taylor, and Sergio M. Loureiro*    2005 Porous ceramics are of great interest for filtration, catalysis, and reactive separation processes. Performance in these applications is highly dependent on features such as pore size distribution and connectivity and wall composition. Here, we describe a method allowing the rational design and synthesis of mesoporous silica composites with controlled heterogeneous pore architectures and demonstrate its validity by producing structures with predetermined placement of regions having different por... 查看全文

3290   Isotope composition of groundwater in the Azov-Kuban and Eastern Pre-Caucasian artesian basins Isotope composition of groundwater in the Azov-Kuban and Eastern Pre-Caucasian artesian basins L. G. Sokolovskii, V. A. Polyakov;H. S. Markidanova    2012 Studying results of the groundwater isotope composition in the Neogene-Quaternary and Mesozoic sediments of the Azov-Kuban and Eastern Pre-Caucasian artesian basins have shown in the Pliocene sediments a rather wide distribution of “relict” groundwater, formed because of melting of the Late Pleistocene Caucasian glaciers, as well as of groundwater formed due to its mixing with the meteogenic waters of the subsequent Holocene infiltration cycles. Also,... 查看全文

3296   Quaternary sequences and their relations to the pre-Quaternary in the vicinity of Anholt, Kattegat, Scandinavia Quaternary sequences and their relations to the pre-Quaternary in the vicinity of Anholt, Kattegat, Scandinavia S. T. Quek, K. K. Phoon and Y. K. Chow    2008 The stratigraphic record from a boring penetrating the 104 m thick Quaternary sequence on the island of Anholt is summarized. The spatial distribution of the pre-Quaternary formations and the surface topography of these are described on the basis of reflection seismic profiles. It is concluded that Anholt is located in the crestal zone of a southeast–northwest trending anticline in the pre-Quaternary. The anticline was formed during the Late Cretaceous–Early Tertiary inversion episod... 查看全文

Jacobson, Natalia Kroutchinina, Julia Khandurina, Robert S. Foote, and J    1998 Polymerase chain reactions (PCRs) were carried out on as many as four DNA samples at a time on a microchip device. The PCR products were then analyzed, either individually or together on the same device, by microchip gel electrophoresis. A standard PCR protocol was used to amplify 199- and 500-base pair (bp) regions of bacteriophage λ DNA and 346- and 410- bp regions of E. coli genomic and plasmid DNAs, respectively. Thermal lysis of the bacteria was integrated into the PCR cycle. A product siz... 查看全文

Quesada, Ramoacute;n Muntilde;oz-Chaacute;puli and Miguel A. Medina    2005 The incidence of Reiter's syndrome in a predominantly white, community-based population is reported. The age-adjusted annual incidence rate for males younger than age 50 was 3.5 per 100,000. No female cases were identified. Over time, a greater proportion of cases have been identified among younger males. In 63% of the patients, either a prolonged or relapsing disease course occurred. 查看全文

During response acquisition, the rate of energy expenditure declines although work rates remain constant and goal achievement increases. When higher response costs are demanded for goal achievement, work rates increase whereas energy expenditure remains constant. Decreases in outcome probability also give rise to increases in motor intensity and work rate but do not influence the rate of energy exp... 查看全文

Schmidt and Heinz-Juuml;rgen Brauch    2006 Contrary to the typical killing action of most animal venoms, including social wasp venoms, the solitary wasp venoms seem to have been created to paralyse the prey. This suggests a specific action on parts of the nervous system. However, the solitary wasp venoms studied, contain many agonists and antagonists of synaptic transmission, and their paralysing action is very complicated. Besides a contribution of agonists to initiate and enhance the action of antagonists, one of the venoms contains tw... 查看全文
