Distinct regulation of Tau Monomer and aggregate uptake and intracellular accumulation in human neurons.

Background: The prion-like spreading of Tau pathology is the leading cause of disease progression in various tauopathies. A critical step in propagating pathologic Tau in the brain is the transport from the extracellular environment and accumulation inside naïve neurons. Current research indicates that human neurons internalize both the physiological extracellular Tau (eTau) monomers and the pathological eTau aggregates.

The International Bathymetric Chart of the Arctic Ocean Version 5.0.

Knowledge about seafloor depth, or bathymetry, is crucial for various marine activities, including scientific research, offshore industry, safety of navigation, and ocean exploration. Mapping the central Arctic Ocean is challenging due to the presence of perennial sea ice, which limits data collection to icebreakers, submarines, and drifting ice stations. The International Bathymetric Chart of the Arctic Ocean (IBCAO) was initiated in 1997 with the goal of updating the Arctic Ocean bathymetric portrayal.

Programme Recipient and Facilitator Experiences of Positive Family Connections for Families of Children With Intellectual Disabilities and/or Who Are Autistic.

Background: Family members of children with developmental disabilities on average report poorer family functioning and mental health. Positive Family Connections is a co-produced, positively-oriented, family-systems support programme for families of children with developmental disabilities aged 8-13. We investigated experiences of Positive Family Connections, and the processes involved in change.

Single-Molecule Multivalent Interactions Revealed by Plasmon-Enhanced Fluorescence.

Multivalency as an interaction principle is widely utilized in nature. It enables specific and strong binding by multiple weak interactions through enhanced avidity and is a core process in immune recognition and cellular signaling, which is also a current concept in drug design. Here, we use the high signals from plasmon-enhanced fluorescence of nanoparticles to extract binding kinetics and dynamics of multivalent interactions on the single-molecule level and in real time.

18F-DCFPyL in the Detection of Prostate Cancer Spread to the Lumbosacral Plexus.

In most cases, prostate cancer spreads locally to the seminal vesicles, via lymphatics to pelvic and abdominal lymph nodes, and hematogenously to the bones. Direct invasion along nerve roots is exceptionally rare but can occur. Here, we present a case with 18F-DCFPyL PET/CT images showing neoplastic involvement of the lumbosacral plexus in a patient with recurrent prostate cancer.
