Biomarkers of Leucine‐Rich Repeat Kinase 2 (LRRK2) and Lysosomal Dysfunction in Progressive Supranuclear Palsy

open access: yesMovement Disorders, EarlyView.
Abstract Background Common and rare genetic variants in leucine‐rich repeat kinase 2 (LRRK2) have been linked with sporadic and familial Parkinson's disease (PD). Recently, we discovered that common genetic variation near the LRRK2 locus determined survival in progressive supranuclear palsy (PSP).

Stable Carbon and Nitrogen Isotope Analysis Explores Diverse Domestic Goose Management Practices in Medieval and Postmedieval Russia

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT Studying goose domestication through archaeological finds has been challenging due to the similar skeletal morphology of the European domestic goose and its wild progenitor, the greylag goose (Anser anser). We analyzed stable carbon (δ13C) and nitrogen (δ15N) isotopes from bone collagen of subfossil domestic and potentially domestic geese to ...

Experimental archaeological study in China: implications for reconstruction of past manuring and dietary practices indicated by δ 15N values of Setaria italica and Panicum miliaceum

open access: yesHeritage Science
Understanding the crop management practices of millet agriculture is pivotal for comprehending the development of Chinese civilization. Recent studies have indicated that organic manuring plays a crucial role in ensuring sustainable millet cultivation on

Urban‐driven homogenization of aquatic subsidy size structure cascades to riparian predator communities

open access: yesOikos, EarlyView.
The export of emergent aquatic insects is a critical energy subsidy for terrestrial food webs. While urbanization is known to alter stream communities, its effects on the size structure of these insect subsidies and the subsequent consequences for riparian predators remain poorly understood.

Enhancing effect of Na2SeO3 on the growth and physiological parameters of Vitis vinifera × labrusca 'Shuijing' under nitrogen deficiency and underlying transcriptomic mechanisms

open access: yesFolia Horticulturae
The differences in physiological characteristics and transcriptional response of grape growth under Na2SeO3 treatment with nitrogen deficiency are explored, and selenium- and nitrogen-responsive genes are screened.

Syntheses of 15N-Labeled Nucleosides

open access: yesJournal of Synthetic Organic Chemistry, Japan, 1996
NMR studies employing oligonucleotides regio-selectively labeled with 15N-atom provide valuable information regarding nucleic acid structures, nucleic acids binding with drugs, and nucleotide-protein interactions. The potential utility of the 15N-labeled oligonucleotides has led to considerable interest in the development of synthetic routes to the ...

Range‐wide sampling reveals cryptic lineages but largely conserved mycorrhizal associations in the Japanese fairy lantern Thismia kobensis

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
The jewel‐like flowers of Thismia are as rare as they are beautiful, often recorded from only a single site per species. Access to 15 populations of T. kobensis has enabled an uncommon, range‐wide assessment of morphology, genetics, and fungal partners. Our analyses showed that T.

Delineating seasonal shifts in reindeer habitat and diet selection by integrating GPS telemetry and stable isotope analysis

open access: yesWildlife Biology, EarlyView.
Seasonal changes shape herbivore behaviour by altering forage availability and habitat conditions; however, few studies integrate diet and habitat selection data across temporal scales. This study uses seasonality as a unifying framework to combine fine‐scale GPS‐based habitat selection data with broader‐scale dietary information from stable isotope ...
