The translocation of signaling molecules in dark adapting mammalian rod photoreceptor cells is dependent on the cytoskeleton.

2008

In vertebrate rod photoreceptor cells, arrestin and the visual G-protein transducin move between the inner segment and outer segment in response to changes in light. This stimulus dependent translocation of signalling molecules is assumed to participate in long term light adaptation of photoreceptors. So far the cellular basis for the transport mechanisms underlying these intracellular movements remains largely elusive. Here we investigated the dependency of these movements on actin filaments and the microtubule cytoskeleton of photoreceptor cells. Co-cultures of mouse retina and retinal pigment epithelium were incubated with drugs stabilizing and destabilizing the cytoskeleton. The actin a…

Production of Cultural Policy in Russia: Authority and Intellectual Leadership

2020

The paper discusses different frameworks of knowledge production within the discourses and practices of Russian cultural policy. Russian cultural policy as an administrative sector has been developed in line with two distinctive governmental regimes, more precisely during the period of liberal decentralisation of the 1990s and the conservative centralisation from 2011 up until today. The study focuses on the main changes that have occurred in the framework of policy design and participation in policy-making. An attempt is made to combine Foucauldian analytical frameworks of power and discourse with a Gramscian hegemonic approach to political studies that was mainly advocated by the Essex sc…

The accuracy of three-dimensional rapid prototyped surgical template guided anterior segmental osteotomy

2019

Background Surgical guiding templates provided a reliable way to transfer the simulation to the actual operation. However, there was no template designed for anterior segmental osteotomy so far. The study aimed to introduce and evaluate a set of 3D rapid prototyping surgical templates used in anterior segmental osteotomy. Material and Methods From August 2015 to August 2017, 17 patients with bimaxillary protrusions were recruited and occlusal-based multi-sectional templates were applied in the surgeries. The cephalometric analysis and 3D superimposition were performed to evaluate the differences between the simulations and actual post-operative outcomes. The patients were followed-up for 12…

Epibiota of juvenile Hawksbill Sea Turtles Eretmochelys imbricata stranded in the coast of Rocha Department, Uruguay

2016

The hawksbill turtle (Eretmochelys imbricata) is the most threatened sea turtle species in the world. An important aspect of the biology of sea turtles is the study of colonizing fauna, i.e., their epibiota. The aim of this study is a taxonomic determination on the epibiota found on 4 hawksbills turtles stranded in 2009 and 2011 on the coast of Rocha Department, Uruguay. The epibiota was composed by algae from the class Phaeophyceae (Sphacelaria sp. and Hincksia mitchelliae) and invertebrates from the classes Cirripedia (Platylepas hexastylos, Chelonibia testudinaria and Amphibalanus improvisus) and Hirudinea (Ozobranchus margoi), with greater predominance of P. hexastylos cirripeds (n= 365…

‘One-Pot’ Synthesis of Raumacline from Ajmaline

1993

For the alkaloid raumacline (2), which is a biotransformation product of ajmaline (1) in Rauwolfia serpentina cell cultures, an efficient ‘one-pot’ synthesis was developed using a NaBH4/riboflavin/light-mediated transformation of 1 into 2 with a total yield of 86%.

Study of the flying geese theory from a political point of view : a Japanese propaganda argument in the post world war II era

2009

The Flying Geese Theory (gankoo keitai hattenron 雁行形態発展論), dating from 1932, is one of the rare cases of a scientific theory that was used as a part of Japanese wartime propaganda, and which also survived and succeeded in the postwar era. It was used to legitimize the 'New Order in East Asia (TōA shinchitsujo 東亜新秩序) in 1938, and the new formulation of the 'Greater East Asia Co-Prosperity Sphere‘ (Dai TōA kyōeiken大東亜共栄圏) in 1940. Later in the 1980s the Flying Geese Theory/Pattern became the most successful candidate for explaining the expansion of ‗Asian economical miracles‘ in the postwar era. This study focuses on this famous piece of economical and political rhetoric. The intention is to …

Comparative study of degassing membrane modules for the removal of methane from Expanded Granular Sludge Bed anaerobic reactor effluent

2016

Abstract The feasibility of an emergent technology for in situ removal/recovery of methane from the effluent of an Expanded Granular Sludge Bed (EGSB) anaerobic reactor has been studied. For this purpose, the performances of two commercial hollow fibre degassing contactors with different membrane materials – microporous (polypropylene, PP) and non-porous (polydimethylsiloxane, PDMS) – were compared. The influence of water fluxes (Q L /A membrane ranging from 22.6 to 377.4 L h −1  m −2 ), vacuum pressure (140–800 mbar), sweep gas fluxes (Q N2 /A membrane ranging from 0.14 × 10 3 to 4.44 × 10 3  L h −1  m −2 ), and mode of operation (liquid flowing in the lumen side or the shell side) was stu…

Simultaneous determination of imidacloprid, carbendazim, methiocarb and hexythiazox in peaches and nectarines by liquid chromatography–mass spectrome…

2002

Abstract A liquid chromatographic (LC) atmospheric pressure chemical ionization mass spectrometric (MS) method is described for determining imidacloprid, carbendazim, methiocarb and hexythiazox in peaches and nectarines. The samples were extracted with ethyl acetate and anhydrous sodium sulfate. Recoveries yield for spiking samples were ranged from 64±9% (R.S.D) for carbendazim to 108±14% (R.S.D.) for hexythiazox at the concentration of 0.1 mg kg−1 (n=5). The correlation coefficients were greater than 0.998 over the range between 0.02 and 2 mg kg−1. The limits of quantitation (LOQ) were 0.02 mg kg−1 for all the pesticides. The applicability of the method to detect and quantify imidacloprid,…

Evaluation of 10 pesticide residues in oranges and tangerines from Valencia (Spain)

2006

Abstract One hundred and sixteen orange and tangerine samples from an agricultural cooperative of the Valencian Community (Spain) were analyzed for bitertanol, carbendazim, hexythiazox, imazalil, imidacloprid, methidathion, methiocarb, pyriproxyfen, thiabendazole, and trichlorfon by liquid chromatography–mass spectrometry (LC–MS) after a conventional multiresidue extraction procedure. Of 52 samples that contained pesticide residues, carbendazim was detected in 27 (51.9%) in the concentration range of 0.02–0.04 mg kg−1, hexythiazox in 22 (42.3%) in the concentration range of 0.02–0.05 mg kg−1, imazalil in 8 (15.0%) in the concentration range of 0.02–1.2 mg kg−1, imidacloprid in 5 (9.6%) in a…
