"Two tribes": Handaxe shape variation shows distinct regional cultural groups in southeastern Britain between 424 000 and 374 000 BP

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT This paper examines regional and chronological variations in Acheulean handaxe morphology during Marine Isotope Stage 11 (c. 425–365 ka BP) in Britain. Using a data set of 737 handaxes from 13 securely dated sites in East Anglia and the Thames Valley, we apply three‐dimensional geometric morphometric analysis to examine morphological ...

Aquatic and Littoral Successions in Various Post‐Mining Sites—Patterns and Possible Use in Ecological Restoration

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Vegetation succession in aquatic and littoral habitats has received much less attention than terrestrial habitats have. We sampled differently aged successional stages at five different types of post‐mining sites, that is, sandpits, stone quarries, clay quarries, brown coal spoil heaps and black coal subsidences, across the Czech Republic ...

Differentiating Nonsuicidal Self‐Injury (NSSI) From Suicide Attempts in Adolescents: A Pilot Study

open access: yesMedicine Bulletin, EarlyView.
ABSTRACT Background Differentiating between nonsuicidal self‐injury (NSSI) and suicide attempts (SA) in adolescents is crucial due to distinct underlying motivations, treatment needs, and potential outcomes associated with each behavior.

bregr: An R Package for Streamlined Batch Processing and Visualization of Biomedical Regression Models

open access: yesMed Research, EarlyView.
ABSTRACT Regression analysis is essential in biomedical research for exploring relationships between phenotypic or clinical outcomes and diverse predictors. However, constructing multiple univariate and multivariate models is often hindered by the lack of robust tools for batch regression in R, forcing researchers to rely on custom scripts.

Pallidal Evoked Resonant Neural Activity as a Candidate Biomarker for Deep Brain Stimulation in Dystonia

open access: yesMovement Disorders, EarlyView.
Abstract Background Deep brain stimulation (DBS) targeted to the globus pallidus (GP) can effectively alleviate dystonia symptoms. However, identifying optimal therapeutic stimulation parameters is challenging due to the manual programming process and the paucity of acute effects of DBS on dystonia symptoms.

The Race to Salvage Glucocerebrosidase: Understanding Small‐Molecule Therapies for GBA1‐Associated Parkinsonism

open access: yesMovement Disorders, EarlyView.
Variants in GBA1, the gene encoding the lysosomal enzyme glucocerebrosidase, cause Gaucher disease and confer an increased risk for parkinsonism. Strategies using small molecules can improve the function of glucocerebrosidase in lysosomes. A clear understanding of the mechanism‐of‐action of these compounds will facilitate development of GBA1‐modulating

Multimodal Imaging Investigation of the Dentato‐Thalamo‐Cortical Pathway in Friedreich's Ataxia

open access: yesMovement Disorders, EarlyView.
Abstract Background Friedreich's ataxia (FRDA) is a spinocerebellar neurodegenerative disorder. The dentato‐thalamo‐cortical (DTC) pathway, an important cerebellar output involved in motor control, plays a crucial role in the neural mechanisms underlying ataxia symptoms in FRDA.

FMRI Approaches to Mapping Cerebrovascular Reactivity: Comparison of Gradient Echo BOLD and Spin Echo BOLD With Arterial Spin Labeling

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To compare markers of cerebrovascular reactivity (CVR) measured with Gradient Echo (GE, T2*w) and Spin‐Echo (SE, T2w) BOLD fMRI with quantitative physiological CVR measured using ASL. Methods CVR, the ability of blood vessels to dilate and increase cerebral blood flow (CBF), can be investigated with ASL fMRI but has a low signal‐to ...

Effect of population reinforcement method, site, and plant characteristics on early establishment of the rare endemic plant species Minuartia smejkalii

open access: yesNordic Journal of Botany, EarlyView.
Many habitat‐specialist plant species have been endangered by fragmentation or destruction of their habitats. Minuartia smejkalii is a serpentinophyte endemic to the Czech Republic. It is highly threatened by recent habitat destruction and fragmentation, calling for effective conservation measures.

Cholecystectomy Is Linked With Lower Respiratory Exchange Ratio and Higher Lipid Oxidation and Sleep Energy Expenditure

open access: yesObesity, EarlyView.
ABSTRACT Objective Cholecystectomy (GBX) may alter energy metabolism, but human evidence is limited. We examined whether GBX alters energy expenditure (EE), respiratory exchange ratio (RER), and substrate oxidation. Methods A total of 384 healthy Southwestern Indigenous American adults (222 males, age 28 ± 6 years) were studied, including individuals ...
