Article Synopsis
- The study evaluates a new meningococcal vaccine (MenABCWY) that combines components of the existing MenB vaccine (4CMenB) and the MenACWY vaccine, aiming to provide broad immunization against various meningococcal strains and ease vaccination schedules.
- Conducted as a phase 3 randomized trial across multiple countries, healthy participants aged 10-25 were assigned to receive different vaccine schedules to assess safety, immune response, and consistency of vaccine lots.
- The trial primarily focused on the immune response to MenB strains, comparing MenABCWY's effectiveness to 4CMenB and evaluating the consistency of immune responses among different production lots of the vaccines.
Article Synopsis
- Meningococcal serogroup B (MenB) vaccination with the 4CMenB vaccine was tested for its effectiveness and safety among 3,651 healthy participants aged 10 to 25, using different dosing schedules (0-2, 0-6, and 0-2-6 months).
- The study measured the immune response through two methods: a test-based approach showing high immune breadth (over 78%) and a responder-based approach indicating a significant percentage of participants achieved strong responses (up to 93.4% for the 0-2-6 schedule).
- The results showed no major differences in effectiveness across the dosing schedules, confirming that the simpler 2-dose regimen (0-2)
Article Synopsis
- - The research focuses on advancements in spinning electrodes for AC-electrospinning technology, specifically using a polyvinyl butyral solution to create nanofibrous structures.
- - It introduces innovative spinning weir-electrodes and examines how various design parameters impact the spinning process's stability and the efficiency of nanofiber production.
- - The study also explores how different electric signal characteristics—like voltage, frequency, and wave shape—affect spinning performance, while providing insights into the defects in the resulting nanofibrous structures through SEM analysis.
Background: Vaccination is the best mode of protection against tick-borne encephalitis (TBE) and its sequelae. The duration of protection and the optimal interval of repeat booster doses are still debated. The current study evaluated the persistence of the antibody response 11-15 years after a first booster vaccination following different primary vaccination schedules with a TBE vaccine (Encepur Adults, manufactured by Bavarian Nordic, previously by GSK).

Background: Magnetic resonance (MR) tractography of the brachial plexus (BP) is challenging due to different factors such as motion artifacts, pulsation artifacts, signal-to-noise ratio, spatial resolution; eddy currents induced geometric distortions, sequence parameters and choice of used coils. Notably challenging is the separation of the peripheral nerve bundles and skeletal muscles as both structures have similar fractional anisotropy values. We proposed an algorithm for robust visualization and assessment of BP root bundles using the segmentation of the spinal cord (SSC, C4-T1) as seed points for the initial starting area for the fibre tracking algorithm.
