Department of Radiology and Nuclear Medicine, St. Olav's University Hospital, Trondheim, Norway; Department of Circulation and Medical Imaging, NTNU - Norwegian University of Science and Technology, Trondheim, Norway.

In medical image analysis, the utilization of biophysical models for signal analysis offers valuable insights into the underlying tissue types and microstructural processes. In diffusion-weighted magnetic resonance imaging (DWI), a major challenge lies in accurately estimating model parameters from the acquired data due to the inherently low signal-to-noise ratio (SNR) of the signal measurements and the complexity of solving the ill-posed inverse problem. Conventional model fitting approaches treat individual voxels as independent.

Disease networks offer a potential road map of connections between diseases. Several studies have created disease networks where diseases are connected either based on shared genes or Single Nucleotide Polymorphism (SNP) associations. However, it is still unclear to which degree SNP-based networks map to empirical, co-observed diseases within a different, general, adult study population spanning over a long time period.

Cyto-, gene, and multireceptor architecture of the early postnatal mouse hippocampal complex.

Prog Neurobiol

December 2024

Institute of Neuroscience and Medicine (INM-1), Research Centre Jülich, Jülich 52425, Germany; C. & O. Vogt Institute for Brain Research, Heinrich-Heine-University, Dusseldorf 40225, Germany.

Neurotransmitter receptors are key molecules in signal transmission in the adult brain, and their precise spatial and temporal balance expressions also play a critical role in normal brain development. However, the specific balance expression of multiple receptors during hippocampal development is not well characterized. In this study, we used quantitative in vivo receptor autoradiography to measure the distributions and densities of 18 neurotransmitter receptor types in the mouse hippocampal complex at postnatal day 7, and compared them with the expressions of their corresponding encoding genes.

Electronic address:

Article Synopsis
  • The study aimed to find the cardiorespiratory fitness (CRF) levels necessary for older adults (70-77 years) to reduce their risk of death, hypothesizing that higher peak oxygen uptake (VO) would be protective.
  • The research included a cohort of 1,565 older adults in Norway, who underwent VO testing and were monitored for all-cause mortality over five years.
  • Results indicated that lower VO levels (less than 26.5 mL/kg/min for men and 22.2 mL/kg/min for women) significantly increased the risk of death, emphasizing the need for maintaining or improving CRF in later life.

Recently, it has been hypothesized that alpha-synuclein protein strain morphology may be associated with clinical subtypes of alpha-synucleinopathies, like Parkinson's disease and multiple system atrophy. However, direct evidence is lacking due to the caveat of conformation-specific characterization of protein strain morphology. Here we present a new cell model based in vitro method to explore various alpha-synuclein (αsyn) aggregate morphotypes.

The crosstalk between the cells and the extracellular matrix (ECM) is bidirectional and consists of a pushing/pulling stretch exerted by the cells and a mechanical resistance counteracted by the surrounding microenvironment. It is widely recognized that the stiffness of the ECM, its viscoelasticity, and its overall deformation are the most important traits influencing the response of the cells. Here these three parameters are combined into a concept of elastic energy, which in biological terms represents the mechanical feedback that cells perceive when the ECM is deformed.

Ultrasound Med Biol

January 2025

Department of Circulation and Medical Imaging (ISB), NTNU - Norwegian University of Science and Technology, Trondheim, Norway; Children's Clinic, St. Olavs Hospital, Trondheim University Hospital, Trondheim, Norway.

Objective: Fat embolism syndrome and cerebral fat emboli are rare yet serious conditions arising from systemic distribution of bone marrow emboli. Emboli are known to produce high-intensity transient signals (HITS) in a Doppler signal. We hypothesized that both intramedullary nailing in pigs and median sternotomy in human infants cause bone marrow release, that some of these cause cerebral emboli, and that these were detectable by a new cerebral doppler ultrasound monitoring system (NeoDoppler).
