Psychopharmacological aspects of catha edulis (khat) and consequences of long term use: a review

open access: yesPsychiatry and Behavioral Sciences, 2011
Catha edulis (khat) is a plant grown commonly in the horn of Africa. Its leaves are chewed by the local people for their stimulant action. The purpose of this review was to summarize the psychopharmacologic aspects of Catha edulis (khat) and consequences

Interpolated Adaptive Linear Reduced Order Modeling for Deformation Dynamics

open access: yesComputer Graphics Forum, EarlyView.
Abstract Linear reduced‐order modeling (ROM) is widely used for efficient simulation of deformation dynamics, but its accuracy is often limited by the fixed linearization of the reduced mapping. We propose a new adaptive strategy for linear ROM that allows the reduced mapping to vary dynamically in response to the evolving deformation state ...

Intrinsic specificity of a ‘core’ TIP60 acetyltransferase complex in Drosophila

open access: yesThe FEBS Journal, EarlyView.
The intrinsic substrate selectivity of the Drosophila TIP60‐core acetyltransferase was determined using synthetic nucleosome arrays. Targeted mass spectrometry revealed site‐specific acetylation of histones H2A, H2A.V, and H4, uncovering distinct acetylation rates and patterns across individual lysines.

Selective targeting of cortactin tandem repeat acetylation by human lysine deacetylases

open access: yesThe FEBS Journal, EarlyView.
Cortactin function is regulated by acetylation at several lysine residues within its tandem repeat region. Using genetic code expansion to generate cortactin variants containing precisely defined acetylation marks, we show that HDAC6 is the primary enzyme removing these modifications, with SIRT1 and SIRT2 also acting at selected sites but with lower ...

Points vs. passes: A comparison between electric fishing techniques for sampling fish populations in upland headwater streams

open access: yesJournal of Fish Biology, EarlyView.
Abstract Point‐abundance sampling by electric fishing (PASE) was compared with single‐pass (DF1) and triple‐pass depletion sampling (DF3) electric fishing on the same reaches of four headwater streams sampled over multiple years in the Ribble catchment, UK. Juvenile salmonids, mostly brown trout Salmo trutta with some Atlantic salmon S.
