Neurofilament Light Chain under the Lens of Structural Mass Spectrometry.

Neurofilament light chain (NfL) is an early nonspecific biomarker in neurodegenerative diseases and traumatic brain injury, indicating axonal damage. This work describes the detailed structural characterization of a selected primary calibrator with the potential to be used in future reference measurement procedure (RMP) development for the accurate quantification of NfL. As a part of the described workflow, the sequence, higher-order structure as well as solvent accessibility, and hydrogen-bonding profile were assessed under three different conditions in KPBS, artificial cerebrospinal fluid, and artificial cerebrospinal fluid in the presence of human serum albumin.

Glial fibrillary acidic protein in Alzheimer's disease: a narrative review.

Astrocytes are fundamental in neural functioning and homeostasis in the central nervous system. These cells respond to injuries and pathological conditions through astrogliosis, a reactive process associated with neurodegenerative diseases such as Alzheimer's disease. This process is thought to begin in the early stages of these conditions.

Safety and efficacy of high thoracic epidural analgesia for chest wall surgery in young adolescents: A retrospective cohort analysis and a new standardised definition for success rate.

Background: Chest wall surgery for the correction of pectus excavatum or pectus carinatum has gained increased interest in recent years. Adequate pain treatment, respiratory physiotherapy and early ambulation are key to improving the outcomes. Although thoracic epidural analgesia is highly effective, its safety is controversial, leading to extensive scrutiny and questioning of its role.

New insights into honey bee viral and bacterial seasonal infection patterns using third-generation nanopore sequencing on honey bee haemolymph.

Honey bees are rapidly declining, which poses a significant threat to our environment and agriculture industry. These vital insects face a disease complex believed to be caused by a combination of parasites, viruses, pesticides, and nutritional deficiencies. However, the real aetiology is still enigmatic.
