Disruption of type I interferon pathway and reduced production of IFN-α by parabens in virus-infected dendritic cells.

Background: Parabens are widely used preservatives commonly found in foods, cosmetics, and industrial products. Several studies have examined the effects of parabens on human health owing to widespread and continuous exposure to them in daily life. However, little is known about their immune-regulatory effects.

Galectin-4 increases the ability of M2 macrophages to enhance antiviral CD4+ T-cell responses.

Galectin-4 (Gal-4) is a β-galactoside-binding protein belonging to the galectin family. Although Gal-4 is known to be involved in several physiologic processes of the gastrointestinal tract, its immunomodulatory roles remain unclear. In this study, we investigated whether Gal-4 influences the function of M1 and M2 macrophages.

Anti-influenza A virus activity by Agrimonia pilosa and Galla rhois extract mixture.

Influenza A virus (IAV) continues to threaten human health. To date, two classes of antiviral drugs have been approved to treat IAV infection, but the continuous emergence of the drug-resistant IAV mutant reinforces the need to develop new antiviral drugs. In this study, we aimed to investigate the anti-IAV activity of an aqueous mixture of Agrimonia pilosa and Galla rhois extracts (APRG64).

Potent antiviral activity of the extract of Elaeocarpus sylvestris against influenza A virus in vitro and in vivo.

Background: Elaeocarpus sylvestris (Lour.) Poir. (Elaeocarpaceae) belongs to a genus of tropical and semitropical evergreen trees, which has known biological activities such as antiviral and immunomodulatory activities.

TCR Transgenic Mice: A Valuable Tool for Studying Viral Immunopathogenesis Mechanisms.

Viral infectious diseases are a significant burden on public health and the global economy, and new viral threats emerge continuously. Since CD4 and CD8 T cell responses are essential to eliminating viruses, it is important to understand the underlying mechanisms of anti-viral T cell-mediated immunopathogenesis during viral infections. Remarkable progress in transgenic (Tg) techniques has enabled scientists to more readily understand the mechanisms of viral pathogenesis.

The Brachial Ankle Pulse Wave Velocity is Associated with the Presence of Significant Coronary Artery Disease but Not the Extent.

Background And Objectives: Arterial stiffness is well known as an important risk factor for cardiovascular disease. At our institution, we assessed the association between arterial stiffness, as determined by brachial ankle pulse wave velocity (baPWV), and the extent of coronary artery disease (CAD), as detected by conventional coronary angiography (CAG) in patients who visited the outpatient clinic for angina without any previous history of heart disease. In addition, we evaluated if the level of baPWV could predict the revascularization as a clinical outcome.

Takayasu's Disease in a Patient with Ulcerative Colitis.

A 35-year-old Korean man with a 10-year history of ulcerative colitis (UC) presented with pain and swelling of the right neck. The patient was diagnosed with Takayasu's arteritis (TA) and had human leukocyte antigen (HLA) B-52, which is frequently found in patients having both UC and Takayasu's disease concurrently on HLA analysis. This case is the first report of a patient with both TA and UC in Korea, to the best of our knowledge.

A case of papillary fibroelastoma in the left ventricle.

Cardiac papillary fibroelastoma (CPF) is a rare and benign primary cardiac neoplasm of unknown prevalence. The incidence of CPF in the left ventricle is lower than that in other parts of the heart. A 65-year-old female was referred to our cardiology department for evaluation of a cardiac mass of the left ventricle.
