A mutation in the voltage-gated sodium channel gene associated with pyrethroid resistance in Latin American Aedes aegypti (2007)
Journal Article

Pyrethroids are commonly used as mosquito adulticides and evolution of resistance to these compounds is a major threat to public health. 'Knockdown resistance' to pyrethroids (kdr) is frequently caused by nonsynonymous mutations in the voltage-gated...

Expression of 3β-hydroxysteroid dehydrogenase, cytochrome P450-c17, and sulfotransferase 2B1 proteins in liver and testis of pigs of two breeds: Relationship with adipose tissue androstenone concentration (2007)
Journal Article

An excessive accumulation of androstenone in pig adipose tissue is a major contributor to the phenomenon of boar taint. Androstenone deposition is dependent on the rate of androstenone biosynthesis in testis and androstenone degradation in liver. The...

Natural and anthropogenic contamination of the Fratta-Gorzone river (Veneto, Italy) (2007)
Journal Article

Stream-bed sediment samples were collected in 2001 and 2004 along the Fratta-Gorzone River (Italy) to assess the level of heavy metal contamination. The river stretch most affected by discharges of tannery effluent showed total and pseudo-total Cr le...

Early embryonic expression patterns of the mouse Flamingo and Prickle orthologues (2007)
Journal Article

The Drosophila melanogaster proteins Flamingo and Prickle act in the planar cell polarity (PCP) pathway, which is required for acquisition of epithelial polarity in the wing, eye, and epidermis. In mammals, PCP signaling has been shown to regulate ce... Read More about Early embryonic expression patterns of the mouse Flamingo and Prickle orthologues.

Unconditional nonlinear stability for convection in a porous medium with vertical throughflow (2007)
Journal Article

Linear and nonlinear stability analyses of vertical throughflow in a fluid saturated porous layer, which is modelled using a cubic Forchheimer model, are studied. To ensure unconditional nonlinear results are obtainable, and to avoid the loss of key...

Implications of dealing with airborne substances and reactive oxygen species: What mammalian lungs, animals, and plants have to say (2007)
Journal Article

A gas-exchange structure interacts with the environment and is constantly challenged by contaminants that may elicit defense responses, thus compromising its primary function. It is also exposed to high concentrations of O2 that can generate reactive...

Global stability for penetrative convection with throughflow in a porous material (2007)
Journal Article

This paper investigates penetrative convection in a layer of porous material saturated with water when there is throughflow present. The density is quadratic in temperature. A linearized instability analysis is derived and compared with a weighted no... Read More about Global stability for penetrative convection with throughflow in a porous material.

Do we expect natural selection to produce rational behaviour? (2007)
Journal Article

We expect that natural selection should result in behavioural rules which perform well; however, animals (including humans) sometimes make bad decisions. Researchers account for these with a variety of explanations; we concentrate on two of them. One... Read More about Do we expect natural selection to produce rational behaviour?.

The cannabinoid Δ9-tetrahydrocannabinol inhibits RAS-MAPK and PI3K-AKT survival signalling and induces BAD-mediated apoptosis in colorectal cancer cells (2007)
