Neuronal hyperexcitability: A key to unraveling hippocampal synaptic dysfunction in Lafora disease

Epilepsia, EarlyView.
Abstract Background and Objective Lafora disease (LD) is a rare progressive disorder caused by mutations in the EPM2A or EPM2B genes, characterized by the accumulation of Lafora bodies, drug‐resistant epilepsy, and cognitive decline. To investigate the early molecular mechanisms of LD, we studied electrophysiological changes in the dentate gyrus (DG ...

An Easy Method to Sample Headspace Pheromones in the Field

Ethology, EarlyView.
Females of the orb‐web spider Argiope bruennichi produces a pheromone to attract males for mating. Most of our knowledge about the pheromone and its strategical use by the females is known from the laboratory. While we have confidence in the validity of these results, we wanted to make sure and measure pheromones in the field.

Automatic Capture Verification in Pacemakers (Autocapture) – Utility and Problems

Indian Pacing and Electrophysiology Journal, 2004
The concept of a closed – loop feedback system, that would automatically assess pacing threshold and self -adjust pacing output to ensure consistent myocardial capture, has many appeals.

SARS‐CoV‐2 nucleocapsid protein variants have differential RNA chaperone activity

The FEBS Journal, EarlyView.
The SARS‐CoV‐2 nucleocapsid (N) protein facilitates RNA annealing through its RBD–IDR2–CTD region, identifying it as a functional RNA chaperone. The Omicron BA.5 variant shows reduced chaperone activity compared to the Wuhan wild‐type protein. Although phosphorylation has no effect on wild‐type N, phosphomimetic modification of BA.5 N restores its RNA ...

Share Repurchases and Investment Policies

Financial Review, EarlyView.
ABSTRACT Our study examines the claim that share repurchases lead to reductions in real investments. Repurchase opponents argue that managers forego valuable investments to conduct opportunistic repurchases, while proponents argue that repurchases return excess cash to shareholders.

Using Eye Lens Stable Isotopes to Identify the Rearing Origin of Fall Age‐0 Walleye (Sander vitreus)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Isotope values in fish eye lenses may be useful in differentiating rearing origins. We compared eye lens isotopic values of fall fingerling age‐0 walleye (Sander vitreus) reared in a hatchery pond, a recirculating aquaculture system (RAS), and a natural lake. Using 10 fish per rearing source, we delaminated layers from one eye lens per fish to

Development and validation of a novel approach for quantifying dimensions of the lateral ligaments in human ankle dissections

Journal of Anatomy, EarlyView.
Traditional measurement techniques in cadaveric dissection fail to account for the changes in soft tissue length during joint movement. We have developed a new, simple method to obtain more accurate measurements of ligament length and validated using the lateral ankle ligaments group.
