Effects of sugar-sweetened beverage intake on the development of type 2 diabetes mellitus in subjects with impaired glucose tolerance: the Mihama diabetes prevention study.

In Japan, the incidence of type 2 diabetes mellitus (T2DM) is increasing for several reasons, including increased consumption of sugar-sweetened beverages (SSBs). However, whether SSBs cause T2DM by excess of energy production resulting in obesity remains unclear. Therefore, the present study was designed to evaluate the effects of SSB intake on the development of T2DM in subjects with impaired glucose tolerance (IGT).

Evaluation of basophil CD203c as a predictor of carboplatin-related hypersensitivity reaction in patients with gynecologic cancer.

The incidence of hypersensitivity reaction (HR) to carboplatin has been reported to increase after repeated use of the drug. However, a reliable ex vivo test to predict HR to carboplatin is not currently available. We evaluated the clinical usefulness of measuring basophil CD203c to predict carboplatin-related HR in this prospective case-control study conducted at Mie University Hospital between October 2009 and September 2010.

Effect of suppressor of cytokine signaling on hepcidin production in hepatitis C virus replicon cells.

Aim:   Hepcidin is a key regulator of systemic iron metabolism and its expression is modulated by hepatitis C virus (HCV) infection. Suppressor of cytokine signaling 1 (SOCS-1) and SOCS-3 act as negative regulators of the Jak/signal transducers and activators of transcription signaling pathway. In this study, we investigated how HCV infection modulates SOCS-1 and SOCS-3 production and how these SOCS proteins affect hepcidin production.

Unidentified virus-like particles are detected in plasmas with elevated ALT levels: are they significant of etiological agent(s) of non-B, non-C hepatitis?

GB virus C (GBV-C) and hepatitis G virus (HGV) have been proposed as new viruses etiologically implicated in non-B, non-C hepatitis, but the morphology of these particular virus particles is still unknown, and most cases of non-A to E hepatitis do not relate to their infections. We tried to visualize virus-like particles (VLPs) in plasma samples from hepatitis B surface antigen- and antibody to hepatitis C virus (HCV)-negative blood donors with elevated alanine aminotransferase (ALT), and examined the association of the virus-like particles and the genomes of parenterally transmissible GBV-C/HGV. Twenty-three plasma samples, 13 with elevated ALT levels and 10 with normal ALT values, from blood donors without infections of hepatitis B virus (HBV) and HCV, were subjected to a 20%-60% sucrose density gradient centrifugation, and virus-like particles were observed by electron microscopy.

The ultrastructural morphology of native hepatitis B virus.

Cell lines (2.2.15 cells) capable of supporting the replication of hepatitis B virus (HBV) DNA and intact viral particles have been established by HBV DNA transfection into HepG2 cells.

Morphological identification of hepatitis C virus E1 and E2 envelope glycoproteins on the virion surface using immunogold electron microscopy.

It is known that hepatitis C virus (HCV) particles are spherical, 55-65 nm particles with fine surface projections of about 6 nm in length and with a 30-35 nm inner core. We have reported that free HCV particles labeled with gold particles specific to the HCV E1 glycoprotein are located in 1.14-1.

Vacuolating cytotoxin A is associated with increased thrombin generation in gastric mucosa.

Background: Activation of the coagulation system is a critical response for both the repair of tissue injury and the host defense against microbial pathogens. Activation of the coagulation cascade culminates with the generation of thrombin. In vitro studies have shown that thrombin protects gastric epithelial cells from injury.

Increased circulating levels of thrombin-activatable fibrinolysis inhibitor in lung cancer patients.

Impairment of fibrinolytic function plays an important role in the mechanism of thrombotic disorders in cancer patients. This study assessed the circulating level of thrombin-activatable fibrinolysis inhibitor in patients with lung cancer and its expression by several lung cancer cell lines. The plasma concentrations of thrombin-activatable fibrinolysis inhibitor were significantly increased in lung cancer patients compared to healthy subjects.

Protective role of activated protein C in lung and airway remodeling.

Recent studies have implicated the protein C pathway in the mechanism of lung and airway remodeling. The effector enzyme of this pathway is activated protein C (APC). Clinical studies have shown that APC generation is decreased in patients with lung injury and airway inflammation and that this decrease is associated with increased collagen deposition in the lung.

Thrombin-activatable fibrinolysis inhibitor and protein C inhibitor in interstitial lung disease.

Intraalveolar activation of the coagulation system due to reduced fibrinolytic function plays a critical role in the pathogenesis of interstitial lung disease. Recently, a new potent inhibitor of fibrinolysis, thrombin-activatable fibrinolysis inhibitor, has been isolated and characterized from human plasma. This study evaluated the levels of thrombin-activatable fibrinolysis inhibitor and protein C inhibitor, another suppressor of fibrinolysis, in the bronchoalveolar lavage fluid from patients with interstitial lung disease.
