Do you have enough space? Habitat selection of insectivorous cave-dwelling bats in fragmented landscapes of Eastern Amazon.
PLoS One
January 2025
Instituto Tecnológico Vale (ITV), Belém, Pará, Brazil.
Individual movements of bats are triggered by their life requirements, limited by their recognition of the environment and risks of moving, and mediated by habitat selection. Mining adds fragmentation and heterogeneity to landscapes, with poorly understood consequences to the life activities of the bats. Cave dwelling bats spend most of their life cycles within caves, and as they constantly forage in external landscapes, their contribution in the input of organic matter to the caves is of paramount importance to the subterranean biodiversity.

Prehosp Emerg Care
January 2025
Graduate School of Health and Welfare, Niigata University of Health and Welfare, 1398 Shimami-cho, Kita-ku, Niigata-shi, 950-3198, Niigata, Japan,
Objectives: To compare the effects of powered and manual stretchers on participants' perceived comfort and measured acceleration during lifting and loading operations.
Methods: This non-randomized, laboratory-based crossover study involved forty-one participants (thirty-one firefighters and ten third-year paramedic students) who served as simulated patients experiencing lifting, lowering, loading, and unloading maneuvers using manual and powered stretchers. Four stretcher types were evaluated: one powered stretcher (Power-PRO™ XT) and three manual stretchers (Matsunaga GT, Exchange 4070, Scad Mate), with each group using the manual stretcher they routinely operated.
Risk prediction for elderly cognitive impairment by radiomic and morphological quantification analysis based on a cerebral MRA imaging cohort.
Eur Radiol
January 2025
Institute of PLA Geriatric Medicine, The Second Medical Center & National Clinical Research Center for Geriatric Diseases, Chinese PLA General Hospital, Beijing, China.
Objective: To establish morphological and radiomic models for early prediction of cognitive impairment associated with cerebrovascular disease (CI-CVD) in an elderly cohort based on cerebral magnetic resonance angiography (MRA).
Methods: One-hundred four patients with CI-CVD and 107 control subjects were retrospectively recruited from the 14-year elderly MRA cohort, and 63 subjects were enrolled for external validation. Automated quantitative analysis was applied to analyse the morphological features, including the stenosis score, length, relative length, twisted angle, and maximum deviation of cerebral arteries.
Background: Characterizing pathological and functional features of the preclinical stage of Alzheimer's Disease (AD) is essential as Amyloid beta (Aβ) and tau, the pathological hallmarks of AD, start to accumulate years prior to the onset of clinical symptoms. Whether Aβ and/or tau are related to the brain's ability to functionally reconfigure in time (functional flexibility) remains unclear despite its important role in behavior and cognition.
Method: We included 233 cognitively unimpaired individuals with family history of AD from the PREVENT-AD cohort who underwent both Positron Emission Tomography (PET) and functional Magnetic Resonance Imaging (fMRI).
Background: People living with dementia (PWD) have upregulated inflammatory pathways, exaggerated metabolic aging, and cellular aging. They also have declines in physical function and heightened fall-risk. Understanding the physiologic factors that influence physical decline and fall-risk in PWD is vital to assess and prevent adverse health outcomes, such as future falls.
