A novel super-resolution microscopy platform for cutaneous alpha-synuclein detection in Parkinson's disease.

Alpha-synuclein (aSyn) aggregates in the central nervous system are the main pathological hallmark of Parkinson's disease (PD). ASyn aggregates have also been detected in many peripheral tissues, including the skin, thus providing a novel and accessible target tissue for the detection of PD pathology. Still, a well-established validated quantitative biomarker for early diagnosis of PD that also allows for tracking of disease progression remains lacking.

Patient perspectives on the role of orthopedic nurse practitioners: a cross-sectional study.

Background: The inclusion of nurse practitioners (NPs) specializing in orthopedics shows potential for improving the quality of care for orthopedic patients. A critical aspect of assessing the feasibility and acceptance of introducing NPs into orthopedic settings involves understanding patients' perspectives on this role. This study aims to explore the receptiveness of orthopedic patients to treatment by orthopedic Nurse Practitioners (NPs).

Super-Resolution-Chip: an platform that enables super-resolution microscopy of co-cultures and 3D systems.

The development of organs-on-a-chip platforms has revolutionized cellular culture by allowing cells to be grown in an environment that better mimics human physiology. However, there is still a challenge in integrating those platforms with advanced imaging technology. This is extremely important when we want to study molecular changes and subcellular processes on the level of a single molecule using super-resolution microscopy (SRM), which has a resolution beyond the diffraction limit of light.

Brain-Targeted Liposomes Loaded with Monoclonal Antibodies Reduce Alpha-Synuclein Aggregation and Improve Behavioral Symptoms in Parkinson's Disease.

Monoclonal antibodies (mAbs) hold promise in treating Parkinson's disease (PD), although poor delivery to the brain hinders their therapeutic application. In the current study, it is demonstrated that brain-targeted liposomes (BTL) enhance the delivery of mAbs across the blood-brain-barrier (BBB) and into neurons, thereby allowing the intracellular and extracellular treatment of the PD brain. BTL are decorated with transferrin to improve brain targeting through overexpressed transferrin-receptors on the BBB during PD.

Evaluation of maternal serum and umbilical cord brain-derived neurotrophic factor (BDNF) levels in COVID-19-infected pregnancies.

Objective: COVID-19 is a disease that affects and damages the neurological system. The aim of this study was to evaluate the fetal neurodevelopmental status through maternal serum and umbilical cord BDNF levels.

Patients And Methods: In this prospective study, 88 pregnant women were evaluated.
