Impact of freeze-thaw cytoablation on aqueous outflow patterns in ex vivo anterior chamber perfusion cultures and whole eyes
2022
Background: Porcine eyes have been widely used as ex vivo models in glaucoma research, as they share similar features with human eyes. Freeze-thawing is a non-invasive technique that has been used to obliterate living cells in anterior segment ex vivo cultures, to prepare them for further research such as cellular repopulation. This technique has previously been shown to reduce the intraocular pressure (IOP) in porcine eyes. The aim of this study was to investigate whether freeze-thaw cytoablation causes corresponding canalogram outflow changes in perfused anterior segment cultures (AFT) and whole porcine eyes (WFT). We hypothesized that the known IOP drop in AFT after trabecular meshwork a…
Rickettsia typhi and Haemophagocytic Syndrome
2017
Appropriate therapy (dexamethasone, cyclosporin, and etoposide) could save the patient in those cases in which the pathogen-direct therapy has not been sufficient by itself to control the disease.
Synthesis and Spectroscopic Properties of Silica−Dye−Semiconductor Nanocrystal Hybrid Particles
2010
We prepared silica-dye-nanocrystal hybrid particles and studied the energy transfer from semiconductor nanocrystals (= donor) to organic dye molecules (= acceptor). Multishell CdSe/CdS/ZnS semiconductor nanocrystals were adsorbed onto monodisperse Stöber silica particles with an outer silica shell of thickness 2-23 nm containing organic dye molecules (Texas Red). The thickness of this dye layer has a strong effect on the energy transfer efficiency, which is explained by the increase in the number of dye molecules homogeneously distributed within the silica shell, in combination with an enhanced surface adsorption of nanocrystals with increasing dye amount. Our conclusions were underlined by…
Is the leadership of the Brent-WTI threatened by China's new crude oil futures market?
2020
Abstract The recent listing of a new crude oil futures contract on the Shanghai International Energy Exchange (INE) has reopened the debate over whether crude oil produced in different countries or locations constitutes a unified world oil market. The aim of this paper is to study the information flows among Brent, West Texas Intermediate (WTI) and the new Medium Sour Crude Oil (SC) futures contract listed on INE futures markets to assess whether the trading of this new futures contract has altered the dominant role of the most traded oil benchmarks in the world. A multiple regression model identifies the Brent futures market as the most influential market in the oil price discovery process…
The MBOAT7-TMC4 Variant rs641738 Increases Risk of Nonalcoholic Fatty Liver Disease in Individuals of European Descent
2016
Background & Aims Nonalcoholic fatty liver disease (NAFLD) is a leading cause of liver damage and is characterized by steatosis. Genetic factors increase risk for progressive NAFLD. A genome-wide association study showed that the rs641738 C>T variant in the locus that contains the membrane bound O-acyltransferase domain-containing 7 gene (MBOAT7, also called LPIAT1) and transmembrane channel-like 4 gene (TMC4) increased the risk for cirrhosis in alcohol abusers. We investigated whether the MBOAT7-TMC4 is a susceptibility locus for the development and progression of NAFLD. Methods We genotyped rs641738 in DNA collected from 3854 participants from the Dallas Heart Study (a multi-ethnic…
Rational assembly and dual functionalization of Au@MnO heteroparticles on TiO2 nanowires
2014
Au–MnO heteroparticles were immobilized on the surface of TiO2 nanowires and tagged subsequently with a fluorescent ligand. The immobilization of the Au@MnO heteroparticles was achieved by functionalizing the TiO2 nanowire support with a polymer containing catechol anchor groups for binding to the metal oxide surface and amine groups for conjugation to the Au domains of the Au@MnO heteroparticles. The Au domain of the resulting TiO2@Au–MnO nanocomposite could be functionalized selectively with a thiol-tagged 24 mer oligomer containing Texas red (SH-ODN-TXS red), whereas a green dye (NBD–Cl) could be anchored selectively to the TiO2 “support” using the free amine groups of the polymeric liga…
"Salvation from unhappines by doing one's best" : a rhetorical analysis on Joel Osteen's sermons in the light of the US culture and values
2014
Tiivistelmä – Abstract Tämä laadullinen tutkimus keskittyy Joel Osteenin saarnoihin. Hän johtaa maan suurinta seurakuntaa, Lakewood-kirkkoa Texasin Houstonissa, USA:ssa. Tutkielma pyrkii vastaamaan kahteen tutkimuskysymykseen: 1) Mitkä ovat Osteenin eniten käyttämät retoriset keinot, ja kuinka ne näkyvät hänen saarnoissaan? 2) Miten Osteen käyttää hyväkseen kristillisiä oppeja ja Raamatun auktoriteettia vedotakseen kuulijoidensa kulttuurillisiin arvoihin? Aineiston prominentit retoriset keinot ovat toisto, kielikuvat, pronominien käyttö sekä pronominien suhde neuvojen ja käskyjen antamiseen. Tarkasteltavat kolme kulttuurista pääarvoa ovat individualismi, itsehoito sekä materialismi. Näiden …
Behavioral and Chemical Investigations of Contact Kairomones Released by the Mud Dauber Wasp Trypoxylon politum, a Host of the Parasitoid Melittobia …
2011
Contact kairomones from the host mud dauber wasp Trypoxylon politum Say (Hymenoptera: Crabronidae) that mediate behavioral responses of its ectoparasitoid Melittobia digitata Dahms (Hymenoptera: Eulophidae) were investigated. Chemical residues from host by-products, the cocoon, and the meconium, induced arrestment behavior of macropterous female parasitoids, while those from the host stage attacked, i.e., the prepupa, did not. Melittobia digitata response to polar and apolar extracts of host by-products indicated kairomone(s) solubility mainly in hexane. GC and GC/MS analysis of cocoon and meconium apolar extracts revealed a mixture of linear carboxylic acids from C(6) to C(18), and both ex…
Silesian Texans – przyczynek do relacji o stanie zachowania muzycznej kultury
2019
Śląscy Teksańczycy, od ponad 150 lat mieszkający w okolicach San Antonio w Teksasie, to dziś grupa szacowana przez niektórych badaczy na ok. 200 tysięcy (1%) mieszkańców tego stanu. Osie-dlali się zwykle grupowo, w przeciwieństwie do tzw. emigrantów brazylijskich z podobnego czasu. Tak powstały i istnieją do dziś osady o nazwach: Panna Maria (tu się wszystko zaczęło), Cesto-chowa, St. Hedwig, Kościuszko, Bandera i inne. Historię osadnictwa, losów rodzin, zachowania języka i kultury materialnej ujmują publikacje, niejednokrotnie niezwykle szczegółowe. Trudno podobny sąd wyrazić o badaniach stanu zachowania kultury muzycznej. Jednocześnie szczątkowe dane, zebrane niejednokrotnie niejako przy …
Pokeri-ilta : etnografinen tutkimus rahapelaamisen yhteisöllisyydestä
2017
Tutkielmani tavoitteena on tutkia mitä merkityksiä opiskelijoiden pokeriyhteisö antaa yhteisölle ja pokeripelille: miksi he pelaavat pokeria ja minkä takia he viettävät aikaa yhteisössä? Peliyhteisön tutkimuksen pohjana käytän sosiologi Michel Maffesolin käsitettä uusheimolaisuus, johon sovellan ja vertaan tutkimaani yhteisöä. Lisäksi käyn läpi yhteisön jäsenten suhtautumista rahapelaamiseen ja erityisesti Texas Hold’em pokerivariaatioon, jota he yhteisössä pelasivat. Tutkimusmetodeina käytän teemahaastattelua sekä passiivista havainnointia ja osallistuvaa havainnointia. Tutkielmaani varten haastattelin viittä yhteisön jäsentä. Passiivista havainnointia yhteisössä toteutin kuukauden ajan ja…
