Screening for Gaucher Disease Using Dried Blood Spot Tests: A Japanese Multicenter, Cross-sectional Survey.

Objective For patients with Gaucher disease (GD), a rare, inherited lysosomal storage disease, obtaining a definitive diagnosis is currently time-consuming and costly. A simplified screening method to measure the glucocerebrosidase (GBA) activity using dried blood spots (DBS) on filter paper has recently been developed. Using this newly developed screening method, we evaluated real-world GD screening in patients suspected of having GD.

Establishment of an abnormal vascular patterning model in the mouse retina.

Abnormalities in retinal blood vessels and neuronal function persist in eyes undergoing retinopathy of prematurity. In this study, we examined morphological and functional changes in retinal blood vessels and neurons in mice that had undergone short-term interruption of retinal vascular development through inhibition of vascular endothelial growth factor (VEGF) signaling. In mice treated with the VEGF receptor tyrosine kinase inhibitor KRN633 on postnatal day (P) 0 and 1, the vascular density in the retinal surface increased by P12, but development of deep retinal vascular plexus and choroidal vasculature was delayed until P14.

Apelin-36 is protective against N-methyl-D-aspartic-acid-induced retinal ganglion cell death in the mice.

Retinal ganglion cell death in glaucoma is caused at least in part by a large Ca influx through N-methyl-D-aspartic acid (NMDA) receptors. Apelin is a peptide originally found in the tissue extracts of bovine stomach. Recent studies have been shown that apelin protects against the ischemic-reperfused injury in the brain.

Ion chromatographic analysis of amines, alkanolamines, and associated anions in concrete.

In order to assess the effectiveness of applying penetrating corrosion inhibitors to the surface of reinforced concrete, it is necessary to devise accurate methods for their detection and quantification. In this paper, methods for ion chromatographic analysis of a variety of amines, alkanolamines, and associated anions, which may be used as corrosion inhibitors for steel reinforcement in concrete, are described. By careful adjustment of the conditions for analysis, these inhibitors were readily identified and quantified in concrete/cement pore solutions or digests.

[Fulminant myocarditis treated with percutaneous cardiopulmonary support and long-term complications: three case reports].

A 16-year-old female underwent percutaneous cardiopulmonary support (PCPS) for treatment-resistant ventricular tachycardia, but she could not be weaned from PCPS early without complications. A 44-year-old female underwent PCPS for low cardiac output syndrome with mainly heparin used for anticoagulation. With long-term PCPS, the activated clotting time became unstable, and she died due to fatal hemorrhagic complications in the acute stage.

Effects of pravastatin on exercise electrocardiography test performance and cardiovascular mortality and morbidity in patients with hypercholesterolemia: Lipid Intervention Study in Kyoto.

The long-term effects of the 3-hydoxy-3-methyl-glutaryl coenzyme A reductase inhibitor, pravastatin, on exercise electrocardiography (ECG) test performance and cardiovascular mortality and morbidity were compared with those of conventional lipid-lowering drugs in hypercholesterolemic patients with no history of myocardial infarction or stroke. One thousand two hundred and seventeen patients were randomly assigned with mean serum cholesterol, triglyceride, high-density lipoprotein (HDL) cholesterol, and low-density lipoprotein (LDL) cholesterol levels of 6.98 +/- 0.

Bradykinin inhibits serum-depletion-induced apoptosis of human vascular endothelial cells by inducing nitric oxide via calcium ion kinetics.

Vascular endothelial cells play important roles in atherogenesis, and bradykinin is associated with atherosclerosis. The effect of bradykinin on apoptosis in human umbilical vein endothelial cells (HUVECs) was investigated, with a focus on Ca2+ kinetics and nitric oxide production. In serum-free conditions, the number of apoptotic cells increased in a time-dependent manner, but this increase was inhibited by bradykinin in a dose-dependent manner.
