A dataset of Antarctic ecosystems in ice-free lands: classification, descriptions, and maps.

Antarctica, Earth's least understood and most remote continent, is threatened by human disturbances and climate-related changes, underscoring the imperative for biodiversity inventories to inform conservation. Antarctic ecosystems support unique species and genetic diversity, deliver essential ecosystem services and contribute to planetary stability. We present Antarctica's first comprehensive ecosystem classification and map of ice-free lands, which host most of the continent's biodiversity.

Software solution for integration of frozen section quality assurance into daily practice.

Objective: Diagnoses rendered using the frozen section (FS) technique during surgical procedures are used to guide intraoperative decisions. Therefore, diagnostic FS errors have the potential to affect patient safety and quality of care. Diagnostic FS errors arise due to both technical and interpretative factors and present a challenge to surgical pathology laboratories to recognize, document, and manage in a timely fashion.

Effects of Lactate on Corticospinal Excitability: A Scoping Review.

Aerobic exercise has been shown to impact corticospinal excitability (CSE), however the mechanism(s) by which this occurs is unclear. Some evidence suggests an increase in blood lactate concentration resulting from exercise may be what is driving these changes in corticospinal excitability. The extent of literature examining this effect and whether it is consistent across the literature is unknown.

Enhanced CB1 receptor function in GABAergic neurons mediates hyperexcitability and impaired sensory-driven synchrony of cortical circuits in Fragile X Syndrome model mice.

Electroencephalographic (EEG) recordings in individuals with Fragile X Syndrome (FXS) and the mouse model of FXS ( KO) display cortical hyperexcitability at rest, as well as deficits in sensory-driven cortical network synchrony. A form of circuit hyperexcitability is observed in cortical slices of KO mice as prolonged persistent activity, or Up, states. It is unknown if the circuit mechanisms that cause prolonged Up states contribute to FXS-relevant EEG phenotypes.
