A reliable disease model is critical to the study of specific disease mechanisms as well as for the discovery and development of new drugs. Despite providing crucial insights into the mechanisms of neurodegenerative diseases, translation of this information to develop therapeutics in clinical trials have been unsuccessful. Reprogramming technology to convert adult somatic cells to induced Pluripotent Stem Cells (iPSCs) or directly reprogramming adult somatic cells to induced Neurons (iN), has allowed for the creation of better models to understand the molecular mechanisms and design of new drugs. In recent times, iPSC technology has been commonly used for modeling neurodegenerative diseases and drug discovery. However, several technological challenges have limited the application of iN. As evidence suggests, iN for the modeling of neurodegenerative disorders is advantageous compared to those derived from iPSCs. In this review, we will compare iPSCs and iN models for neurodegenerative diseases and their potential applications in the future.

Background And Objectives: In the era of precision medicine, genetic test results have become increasingly relevant in the care of patients with Parkinson disease (PD). While large research consortia are performing widespread research genetic testing to accelerate discoveries, debate continues about whether, and to what extent, the results should be returned to patients. Ethically, it is imperative to keep participants informed, especially when findings are potentially actionable.

Background And Aims: Porto-sinusoidal vascular disorder (PSVD) is a rare vascular liver disorder characterised by specific histological findings in the absence of cirrhosis, which is poorly understood in terms of pathophysiology. While elevated hepatic copper content serves as diagnostic hallmark in Wilson disease (WD), hepatic copper content has not yet been investigated in PSVD.
Methods: Patients with a verified diagnosis of PSVD at the Medical University of Vienna and available hepatic copper content at the time of diagnosis of PSVD were retrospectively included.

Reactive oxygen species (ROS) play essential roles in both physiological and pathological processes. Under physiological conditions, appropriate amounts of ROS play an important role in signaling and regulation in cells. However, too much ROS can lead to many health problems, including inflammation, cancer, delayed wound healing, neurodegenerative diseases (such as Parkinson's disease and Alzheimer's disease), and autoimmune diseases, and oxidative stress from excess ROS is also one of the most critical factors in the pathogenesis of cardiovascular and metabolic diseases such as atherosclerosis.

This paper introduces the current status of Seoul National University Hospital Dementia Brain Bank (SNUH-DBB), focusing on the concordance rate between clinical diagnoses and postmortem neuropathological diagnoses. We detail SNUH-DBB operations, including protocols for specimen handling, induced pluripotent stem cells (iPSC) and cerebral organoids establishment from postmortem dural fibroblasts, and adult neural progenitor cell cultures. We assessed clinical-neuropathological diagnostic concordance rate.

Peripheral neurodegenerative diseases induced by irreversible peripheral nerve degeneration (PND), such as diabetic peripheral neuropathy, have a high prevalence worldwide and reduce the quality of life. However, there is no agent effective against the irreversible PND. After peripheral nerve injury, Schwann cells play an important role in regulating PND.
