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.

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.

Breaking down IgA: Tomasiella immunophila enlightens microbiome-immune interactions.

The recent discovery by Lu and colleagues of Tomasiella immunophila, a bacterium that degrades IgA, offers insights into microbial influences on mucosal immunity and evolutionary immune trade-offs. By modulating IgA titers, T. immunophila influences the dynamic interactions and balance between the host and pathogen.

Rate-Engineered Plasmon-Enhanced Fluorescence for Real-Time Microsecond Dynamics of Single Biomolecules.

Single-molecule fluorescence has revealed a wealth of biochemical processes but does not give access to submillisecond dynamics involved in transient interactions and molecular dynamics. Here we overcome this bottleneck and demonstrate record-high photon count rates of >10 photons/s from single plasmon-enhanced fluorophores. This is achieved by combining two conceptual novelties: first, we balance the excitation and decay rate enhancements by the antenna's volume, resulting in maximum fluorescence intensity.

Methods: All adult pancreas transplants between February 1, 1983 and December 31, 2023 at the University of Minnesota were reviewed, including pancreas transplant alone (PTA), simultaneous pancreas-kidney transplants (SPK), and pancreas after kidney transplants (PAK).

Qualitative interview with mothers of moderately or late preterm infants in the UK: where are the care gaps?

Introduction: Preterm birth (<37 gestational weeks) accounts for an increasing proportion of global births each year, with moderately or late preterm birth (MLPT) (32-36 gestational weeks) comprising over 80% of all preterm births. Despite the frequency, MLPT births represent only a small fraction of prematurity research, with research exploring the parental experiences of having a child born MLPT particularly neglected. It is vital this perspective is considered to provide appropriate grounding for future research and service provision.
