Mechanistic studies on aziridinylbenzoquinones and CCNU [l-(2-chloroethyl)- 3-cyclohexyl-l-nitrosourea] in cultured tumour cells
… second alkylating agent studied was RH1 (2, 5-diaziridinyl-3 -hydroxymethyl-6-methyl-1, 4-benzoquinone) which is a novel water soluble prodrug which is currentlyundergoing clinical trials. The activity of RH1 was compared with a new lipophilic esterderivative of RH1, Es5. It was found …

Molekulare und physiologische Charakterisierung des Energiestoffwechsels von Nitrosomonas europaea
… Ammoniaktransporters vom Rhesus-Typ (Rh1) in N. europaea zu beweisen. Der passive Rh1-Transporter ermöglicht sowohl die Aufnahme von Ammoniak als auch von Methylammonium (MA) in das Cytoplasma von N. europaea. Die Menge an transportiertem MA korreliert dabei mit der Expression von Rh1. …

Charakterisierung eines parvoviralen Hybridvektors hinsichtlich der Transduktion und präferentiellen Expression in transformierten Zellen
… einem AAV-2 Vektor sollte diesem Hybridvektor TRH1 neue Eigenschaften verleihen. Die Eigenschaften des Hybridvektors TRH1 wurden einerseits hinsichtlich der Transduktion charakterisiert, andererseits bezüglich einer selektiven Expression in transformierten Zellen. Der Hybridvektor TRH1-GFP …

Visual Opsin Diversity in Anurans
… retinas. Amino acid sequences of the genes RH1, LWS, SWS1, and SWS2 were compared across taxa to identify variable sites, as such variation can shift the spectral sensitivity of visual pigments and thus alter dim-light and color vision. Some of the amino acid changes observed are known to …

Reactivity of rhodium-heteroatom bonds: from catalytic bond activation to new strategies for olefin functionalization
… functionalization reactions of olefins. RTPA)Rh111(K2-C,0-2-oxyethyl)]+ BPh4- was prepared by two published methods with limited success. A third method involved the use of nitrous oxide to oxygenate [(12-ethene)(K4-TPA)Rh1]+ to RTPA)Rh1110(-2-C,0-2-oxyethyDr. Only a trace amount of …

Evolution and functional specializations in nocturnal environments: insights from visual pigments in Chiroptera
… of the dim-light visual pigment rhodopsin (Rh1) in response to echolocation, a remarkable sensory adaptation of bats. In Chapter 4, I experimentally characterize rhodopsin of several bat species and find that changes in kinetic properties that influence dim-light visual performance are …

Molecular Evolution and Functional Characterization of the Visual Pigment Proteins of the Great Bowerbird (Chlamydera nuchalis) and Other Vertebrates
… model systems. Chapter 4 examines C. nuchalis RH1 using a number of functional assays in addition to absorbance spectra, including hydroxylamine sensitivity and the rate of retinal release. This chapter includes an investigation into the role of amino acid mutations typical of dim-light adapted …

Structural, molecular and functional characterisation of visual photoreceptors and opsins in sole: an ontogenetic, chronobiological and environmental approach
… visuales, y en particular, de la rodopsina (Rh1), y de las cono-opsinas sensibles a longitudes de onda corta (Sws1 y Sws2), longitudes de onda media (Rh2.3 y Rh2. 4) y longitudes de onda larga (Lws), en especímenes de lenguado mantenidos en ciclos de luz-oscuridad con luz blanca (LDW), azul …
