On Monomial Flocks

open access: yesEuropean Journal of Combinatorics, 2001
A flock of a quadratic cone is a partition of a quadratic cone minus its vertex (in 3-dimensional projective space) into plane conics. These objects give rise to a lot of other interesting objects such as translation planes, elation generalized quadrangles, (herds of) ovals, ovoids, regular hyperbolic fibrations, etc. If the associated functions of the

Effects of the compulsory indoor confinement of organic layer poultry: a dust storm! [PDF]

open access: yes, 2006
In August 2005 an order was issued in the Netherlands for free range poultry to be kept indoors to prevent the introduction of avian influenza. The Animal Sciences Group of Wageningen UR (Wageningen University and Research Centre) conducted a telephone ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Workshop and desk study to appraise technical difficulties associated with organic breeder flocks and organic hatching [PDF]

open access: yes, 2003
BACKGROUND To date, Regulation (EC) 1804/1999 and UKROFS Standards allow conventionally produced day old chicks up to three days of age to be brought into systems of organic table chicken production.

Collective decision making and social interaction rules in mixed-species flocks of songbirds

open access: yesAnimal Behaviour, 2014
Associations in mixed-species foraging groups are common in animals, yet have rarely been explored in the context of collective behaviour. Despite many investigations into the social and ecological conditions under which individuals should form groups ...

Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
