Linking Functional Traits To Trophic Roles In Scavenger Assemblages.

Scavenging is a widespread feeding strategy involving a diversity of taxa from different trophic levels, from apex predators to obligate scavengers. Scavenger species play a crucial role in ecosystem functioning by removing carcasses, recycling nutrients and preventing disease spread. Understanding the trophic roles of scavenger species can help identify specialized species with unique roles and species that may be more vulnerable to ecological changes.

Liver Transplantation for Polycystic Disease: Experience and Results of a Single-Center Series.

Polycystic liver disease (PLD) is a hereditary condition, and its symptoms are due to the growth of cysts. Liver transplantation (LT) is the only curative treatment. A retrospective single-center analysis was conducted on the 10 LTs performed for PLD between 2004 and 2023.

Biomarkers.

Background: The ARTS biomarker is a fully automated software container that predicts the presence of arteriolosclerosis based on in-vivo MRI data and demographic features. The present study describes findings from the instrumental and clinical validation of ARTS conducted by the MarkVCID consortium.

Method: Instrumental validation of ARTS involved assessment of inter-rater reliability, test-retest repeatability, and inter-scanner reproducibility.

Biomarkers.

Background: Limbic-predominant age-related TDP-43 encephalopathy neuropathological change (LATE-NC) is common in older adults and has been associated with substantial cognitive impairment. However, the association of LATE-NC with brain morphometry has not been thoroughly investigated. In this work, we examined the association of LATE-NC with brain morphometric anomalies using deformation-based morphometry (DBM) in a large community cohort of older adults that came to autopsy (N=897).

Biomarkers.

Background: Recent research emphasizes the significance of white matter tracts and the free-water (FW) component in understanding cognitive decline. The goal of this study is to conduct a large-scale assessment on the role of white matter microstructure on longitudinal cognitive decline.

Method: This study used a cohort collated from seven longitudinal cohorts of aging (ADNI, BIOCARD, BLSA, NACC, ROS/MAP/MARS, VMAP, and WRAP).
