Kinetics in signal transduction pathways involving promiscuous oligomerizing receptors can be determined by receptor specificity: Apoptosis induction by TRAIL
(American Society for Biochemistry and Molecular Biology, 2012)Here we show by computer modeling that kinetics and outcome of signal transduction in case of hetero-oligomerizing receptors of a promiscuous ligand largely depend on the relative amounts of its receptors. Promiscuous ... -
The nature of fracture permeability in the basement greywacke at Kawerau Geothermal Field, New Zealand
(Stanford University, 2012-01-30)The Mesozoic basement at Kawerau Geothermal Field comprises well indurated, inter-bedded sandstones and argillites with a complex structural history. These rocks have very low matrix porosity but nonetheless host both ... -
Stress management at the ER: regulators of ER stress-induced apoptosis.
(Elsevier, 2012-02-17)The endoplasmic reticulum (ER) is an elaborate cellular organelle essential for cell function and survival. Conditions that interfere with ER function lead to the accumulation and aggregation of unfolded proteins which are ... -
The Vibrio parahaemolyticus ToxRS Regulator Is Required for Stress Tolerance and Colonization in a Novel Orogastric Streptomycin-Induced Adult Murine Model
(American Society for Microbiology, 2012-03)Vibrio parahaemolyticus, a marine bacterium, is the causative agent of gastroenteritis associated with the consumption of seafood. It contains a homologue of the toxRS operon that in V. cholerae is the key regulator of ... -
Cell cycle-dependent mobility of Cdc45 determined in vivo by fluorescence correlation spectroscopy
(Public Library of Science, 2012-04-19)Eukaryotic DNA replication is a dynamic process requiring the co-operation of specific replication proteins. We measured the mobility of eGFP-Cdc45 by Fluorescence Correlation Spectroscopy (FCS) in vivo in asynchronous ... -
Cell wall evolution and diversity
(Frontiers Media, 2012-07-06)Plant cell walls display a considerable degree of diversity in their compositions and molecular architectures. In some cases the functional significance of a particular cell wall type appears to be easy to discern: secondary ... -
Fabrics produced mimetically during static metamorphism in retrogressed eclogites from the Zermatt-Saas zone, Western Italian Alps
(Elsevier, 2012-09-12)Lattice preferred orientations (LPOs) are commonly interpreted to form by dislocation creep. Consequently they are used to infer deformation at the metamorphic grade at which the minerals were stable, especially if those ... -
Impact of trichloroethylene exposure on the microbial diversity and protein expression in anaerobic granular biomass at 37°C and 15°C
(Hindawi Publishing Corporation, 2012-09-14)Granular biomass from a laboratory-scale anaerobic bioreactor trial was analysed to identify changes in microbial community structure and function in response to temperature and trichloroethylene (TCE). Two bioreactors ... -
Late-interseismic state of a continental plate-bounding fault: Petrophysical results from DFDP-1 wireline logging and core analysis, Alpine Fault, New Zealand
(American Geophysical Union (AGU), 2013)We present a geophysical characterization at 0.1-100 m scales of a major plate-bounding continental fault in a late-interseismic state. The Alpine Fault produces M-W approximate to 8 earthquakes every 200-400 years and ... -
A7 Makaroro River dam site Phase 1C: Field characterisation of possible secondary fault displacement
(GNS Science, 2013)GNS Science has undertaken a field study to investigate the possibility of active secondary faulting in the vicinity of the proposed A7 dam site on the Makaroro River, central Hawke’s Bay. The A7 site is located c. 750 ... -

Listeria monocytogenes has a functional gamma-aminobutyrate (GABA) shunt: Role in acid tolerance and succinate biosynthesis.
(American Society for Microbiology, 2013)Listeria monocytogenes, the causative agent of human listeriosis, is known for its ability to withstand severe environmental stresses. The glutamate decarboxylase (GAD) system is one of the principal systems utilized by ... -
Interpretive review of the acoustic borehole image logs acquired to date in the Wairakei-Tauhara Geothermal Field

Ecological variation in response to mass-flowering oilseed rape and surrounding landscape composition by members of a cryptic bumblebee complex
(Public Library of Science, 2013-06-19)The Bombus sensu stricto species complex is a widespread group of cryptic bumblebee species which are important pollinators of many crops and wild plants. These cryptic species have, until now, largely been grouped together ... -
Response of farmland biodiversity to the introduction of bioenergy crops: effects of local factors and surrounding landscape context
(Wiley Open Access, 2013-07-19)The recent growth in bioenergy crop cultivation, stimulated by the need to implement measures to reduce net CO2 emissions, is driving major land-use changes with consequences for biodiversity and ecosystem service provision. ... -
Low-temperature (10°C) anaerobic digestion of dilute dairy wastewater in an EGSB bioreactor: microbial community structure, population dynamics, and kinetics of methanogenic populations
(Hindawi Publishing Corporation, 2013-07-25)The feasibility of anaerobic digestion of dairy wastewater at 10 degrees C was investigated in a high height : diameter ratio EGSB reactor. Stable performance was observed at an applied organic loading rate (OLR) of 0.5-2 ... -
Cell cycle-dependent formation of Cdc45-Claspin complexes in human cells is compromized by UV-mediated DNA damage
(Wiley, 2013-08-02)The replication factor Cdc45 has essential functions in the initiation and elongation steps of eukaryotic DNA replication and plays an important role in the intra-S-phase checkpoint. Its interactions with other replication ... -
Contrasting responses to nutrient enrichment of prokaryotic communities collected from deep sea sites in the Southern Ocean
(MDPI Open-Access Journals, 2013-09-13)Abstract: Deep water samples (ca. 4,200 m) were taken from two hydrologically-similar sites around the Crozet islands with highly contrasting surface water productivities. Site M5 was characteristic of high productivity ... -
