This paper analyses the notch effect in the fracture behaviour of acrylonitrile-styrene-acrylate (ASA) material manufactured by fused filament fabrication (FFF). The research is performed on 72 single-edge-notch bending (SENB) specimens containing U-notches with nominal notch radii varying from 0 mm (crack-like defects) up to 2.0 mm, and fabricated with three different raster orientations (0/90, 45/-45, 30/-60).

- - MV PLUS lesions are benign brain cysts that usually do not cause symptoms but can lead to neurological issues like seizures and headaches; they are mainly found in the posterior fossa and detected through MRI scans showing high intensity on T2-FLAIR sequences.
- - A case of a 52-year-old woman with symptoms like dizziness and syncope revealed a multicystic lesion via MRI, which showed no harmful changes after treatment, highlighting the need for careful monitoring and further research.
- - These lesions pose diagnostic challenges due to their complex features; although benign, their management and pathogenesis are still being studied, stressing the importance of ongoing investigation in the field.
Article Synopsis
- A report studied how a special imaging test called 18 F-PBR06-PET can help find signs of brain cell problems in people with multiple sclerosis (MS).
- The study looked at 30 scans from 22 MS patients and compared their results with 8 healthy people to see how effective different treatments were.
- Results showed MS patients had higher brain activity scores than healthy people, and even though stronger treatments helped reduce this activity, it still wasn't completely normal, linking it to their symptoms and brain changes.
Article Synopsis
- * Anticholinergic medications can effectively treat conditions like drug-induced parkinsonism and dystonia but are not suitable for tardive dyskinesia, akathisia, or neuroleptic malignant syndrome.
- * Caution is advised when prescribing anticholinergics due to their potential serious side effects, especially in older patients; they should be used at the lowest effective dose and tapered off gradually.
Objective: This study aimed to rigorously assess the accuracy of mixed-reality neuronavigation (MRN) in comparison with magnetic neuronavigation (MN) through a comprehensive phantom-based experiment. It introduces a novel dimension by examining the influence of blue-green light (BGL) on MRN accuracy, a previously unexplored avenue in this domain.
Methods: Twenty-nine phantoms, each meticulously marked with 5-6 fiducials, underwent CT scans as part of the navigation protocol.
