Therapeutic potential of small molecules that block receptor‐induced Kv7/M‐current suppression in neuroprotection, seizures, and pain

open access: yesBritish Journal of Pharmacology, EarlyView.
Receptor‐induced Kv7/M‐current suppression increases neuronal activity and contributes to pathology of several conditions. A new class of Kv7 modulators identified in this study attenuates M‐current suppression and shows therapeutic effects. Abstract Background and Purpose Neuronal Kv7 channels generate low voltage–gated potassium currents known as the

Novel Hydrurus species (Chrysophyceae) and their adaptations to high‐altitude European and Arctic snowfields

open access: yesJournal of Phycology, EarlyView.
Abstract Colored snow caused by green algae (Chlorophyceae) is well known, but melting snowpacks can also harbor golden‐brown blooms consisting of Chrysophyceae. We collected 14 samples of cryoflora in the Austrian and Swiss Alps, the High Tatras in Slovakia, and in Arctic Svalbard. Eight laboratory unicellular flagellated strains were established from

Germanium Single Crystals for Photonics

open access: yesCrystals
Germanium (Ge) is a system-forming material of IR photonics for the atmospheric transparency window of 8–14 µm. For optics of the 3–5 µm range, more widespread silicon (Si), which has phonon absorption bands in the long-wave region, is predominantly used.

Observation of Solitonic Vortices in Bose-Einstein Condensates

open access: yes, 2014
We observe solitonic vortices in an atomic Bose-Einstein condensate after free expansion. Clear signatures of the nature of such defects are the twisted planar density depletion around the vortex line, observed in absorption images, and the double ...

Sound offset responses become highly informative in the auditory cortex

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Using large datasets of neural responses to diverse sounds recorded across four stages of the mouse auditory system (depicted and colour‐coded on the left), offset responses occurring after the termination of each sound (time window indicated by the orange shaded area superimposed with activity traces) were characterized and it ...
