Structural Mechanism of an Efficacy Photoswitch Targeting the β2‐adrenergic Receptor [PDF]

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 18, 27 April 2026.
Time‐resolved structures from x‐ray free‐electron laser measurements combined with cellular assays demonstrate how the photoswitchable β‐blocker photoazolol‐1 acts as an efficacy switch of β2‐adrenergic receptor function. Light‐induced ligand repositioning shifts activity from inverse agonism toward neutral antagonism by altering local helical ...

Intercourse as Discourse in Alexa Hennig von Lange’s Relax

open access: yesStudies in 20th & 21st Century Literature, 2011
While gender has long been an abiding concern of Popliteratur , pop writers (in particular female authors) are often criticized for simply reflecting, if not positively endorsing, negative forms of postfeminism—an attitude that negates the ...

Breakdown points for maximum likelihood estimators of location-scale mixtures [PDF]

open access: yes, 2004
ML-estimation based on mixtures of Normal distributions is a widely used tool for cluster analysis. However, a single outlier can make the parameter estimation of at least one of the mixture components break down. Among others, the estimation of mixtures

Taxonomic revision of two poorly known genera of Richardiidae (Diptera): Maerorichardia and Odontomerella

open access: yesZoologia (Curitiba), 2015
Richardiidae are a family of Tephritoidea in which most genera are poorly known taxonomically, including some which were poorly described with limited or no illustrations.

Interaction of Cucurbit[7]uril With Protease Substrates: Application to Nanosecond Time-Resolved Fluorescence Assays

open access: yesFrontiers in Chemistry, 2020
We report the use of the macrocyclic host cucurbit[7]uril (CB7) as a supramolecular additive in nanosecond time-resolved fluorescence (Nano-TRF) assays for proteases to enhance the discrimination of substrates and products and, thereby, the sensitivity ...

Discriminating depression, physical and social anhedonia by neurotransmitter related challenge tests [PDF]

open access: yes, 2016
The aim of this study was to investigate, if anhedonia, a salient component of depression, shows similar response patterns to neurotransmitter challenge tests as depression, and if the two questionnaire based components Physical (PA) and Social (SA ...

Social Facts Explained and Presupposed [PDF]

open access: yes, 2006
Attempts are often made to explain collective action in terms of the interaction of individuals. A common objection to such attempts is that they are circular: Since every interaction presupposes the existence of common practices and common practices ...
