Serum Neurofilament Light Chain and Glial Fibrillary Acidic Protein as Biomarkers in Hereditary Transthyretin Amyloidosis Polyneuropathy

open access: yesJournal of the Peripheral Nervous System, Volume 31, Issue 1, March 2026.
ABSTRACT Background and Aims In individuals with hereditary transthyretin amyloidosis (ATTRv) polyneuropathy, monitoring of disease progression and treatment response is crucial. The objective is to determine if serum neurofilament light chain (sNfL) and serum glial fibrillary acidic protein (sGFAP) are reliable biomarkers of ATTRv polyneuropathy ...

The Vikings and their importance for the North Atlantic (Iceland, Greenland, North America) from the beginning of the expansion in the 9th century until the extinction around 1400

open access: yesStudia Humanitatis, 2020
The Viking colony in West Greenland has always interested historians, archaeologists and climatologists. How could the community of 4,000-5,000 Viking peasants survived in Arctic Greenland for 425 years (985-1400), and why did they finally disappeared ...

Laser Ablation Sampling With Low‐Power Plasma: A LA‐MIP‐MS Instrument for Spaceflight

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 3, 15 February 2026.
ABSTRACT Rationale Inductively coupled plasma (ICP) is a commonly used ion source for mass spectrometry‐based chemical analysis of a wide range of materials. Traditional ICP ion sources use high power (> 1000 W) and significant gas flow (> 10 L/min), rendering them unsuitable for spaceflight, as they are too resource‐intensive for planetary spacecraft.

Notes From the Era of Pre‐Modern Fishing in the Baltic Sea Reveal an Extensive and Resilient Fishing Mode

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.
ABSTRACT In the past half‐century, fishing in one regional part of the Baltic Sea, the Stockholm Archipelago, has almost disappeared due to falling fish abundance, especially of herring (Clupea harengus). By examining published observations and archived material on historical fishing patterns, we found evidence of a remarkably continuous high level of ...

Saltation on Mars and expected lifetime of Viking 75 wind sensors [PDF]

open access: yes
With the use of the wind-tunnel measurements of Bagnold and Zingg, a model is developed for estimating the parameters that describe the flux of sand on Mars. Application of this model to the sensor-breakage problem indicates that the expected lifetime on
