This paper suggests an alternative approach to measuring systemic risk in financial markets by examining the interconnectedness among heterogeneous investors. Utilizing variance decomposition and a trading database from the Korea Stock Exchange spanning 2002-2018, we find that systemic risk, as quantified by total connectedness based on microlevel investor activity, intensifies during both domestic and global financial crises. In addition, our analysis indicates that retail investors, often termed noise traders, are pivotal contributors to the propagation of financial shocks. We also find that portfolios constructed by the sensitivity of total connectedness yield additional returns. This study could enhance our understanding of the contagion effect by incorporating the investor perspective, and the findings could offer valuable insights for policy-makers and regulators.

Maternal immune activation (MIA) is a principal environmental risk factor contributing to autism spectrum disorder (ASD) and can be causally linked to ASD symptoms. In our study, we found that MIA triggered by poly (I: C) injection caused ventriculomegaly in offspring due to the dysfunction of the choroid plexus (Chp) and ependyma. We subsequently identified a sustained enhancement of interferon-γ (IFN-γ) signaling in the brain and serum of MIA offspring.

Organophosphate (OP) nerve agents, such as soman (GD), pose great risk to neurological health by inhibiting acetylcholinesterase, leading to seizures, epilepsy, and behavioral deficits. While acute treatment may alleviate immediate symptoms, the long-term consequences, particularly those involving neuroinflammation and systemic toxicity, remain poorly understood. This study used adult male and female Sprague Dawley rats to investigate the chronic effects of a single acute exposure to soman (132 µg/kg, s.

Psoriasis, a chronic inflammatory systemic disease, may increase the risk of allergic diseases. This meta-analysis assesses the prevalence and risk of developing allergic rhinitis in psoriasis. We systematically searched MEDLINE, Scopus, and EMBASE for population-based studies documenting AR in psoriasis compared to those without from inception to December 2023.

Purpose: To investigate the incidence and ophthalmic complications of pediatric uveitis using the Korean National Health Insurance (NHI) Service database.
Design: Nationwide population-based longitudinal cohort study.
Methods: This study used the NHI database from 2005 to 2021 and included individuals <18 years of age diagnosed with uveitis on at least three separate visits between 2010-2014, with a five-year wash-out period and a seven-year follow-up period.
