The framework of homeostatic plasticity posits that neurons regulate cellular properties through feedback homeostasis to maintain activity during changes in the environment. However, when disturbances occur in wild animals they are often caused by environmental variables that induce their own acclimation effects, making it difficult to discern if activity-sensitive feedback plays a role in ecological […]
In temperate regions, several mosquito species overwinter as diapausing females in sheltered habitats, enabling them to serve as early-season vectors of mosquito-borne pathogens. While overwintering species compositions have been documented in several parts of Europe, no comprehensive data exist for Estonia or for the Baltic region. This study aimed to investigate the species composition of […]
This preamble honors the late evolutionary primatologists Judith Masters and Fabien Génin, synthesizing their profound impact on strepsirrhine anatomy, systematics, and biogeography. Over four decades, Masters applied Hugh Paterson's Recognition Concept of species alongside comprehensive craniodental morphometrics and phylogenetics to reframe the evolutionary trees of nocturnal African galagos, culminating in the formal description of the […]
Memory allows animals to utilize ecologically relevant information, yet whether it endures through prolonged metabolic shutdown is poorly understood. We tested spatial memory retention in a long-term, free-living hibernator, the Columbian ground squirrel (Urocitellus columbianus), using a field-based spatial maze over two consecutive active seasons. Ten individuals were tested before and after a 9-month hibernation […]
CONCLUSIONS: [68Ga]Ga-FAPI-46 PET/CT enables noninvasive visualization of active fibroblast-associated myocardial remodeling following MI. Integrated assessment with [18F]FDG PET demonstrated spatially heterogeneous FAPI uptake involving metabolically inactive infarct regions and, in a subset of patients, adjacent FDG-preserved myocardium. The complementary information provided by these radiotracers may improve biological characterization of post-infarction myocardial remodeling, although the...
