Neurons are polarized cells that contain distinct sets of proteins in their axons and dendrites. Synaptic vesicles (SV) and many SV proteins are exclusively localized in the presynaptic regions but not in dendrites. Despite their fundamental importance, the mechanisms underlying the polarized localization of SV proteins remain unclear. The transparent nematode Caenorhabditis elegans can be used...

We present a noninvasive method to measure the venous oxygen saturation (Sv(O(2))) in tissues using near-infrared spectroscopy (NIRS). This method is based on the respiration-induced oscillations of the near-infrared absorption in tissues, and we call it spiroximetry (the prefix spiro means respiration). We have tested this method in three piglets (hind leg) and in eight human subjects (vastus ...

INTRODUCTION Little is known about the risk and protective factors for youth sexual violence (SV) perpetration across different types of relationships. This study examined factors associated with perpetrating SV against a dating partner and a same-sex peer. METHODS Analyses were based on data from a survey conducted in 2004 with public school boys and girls in grades 7, 9, 11, and 12 (N = 4,1...

Background: Interventional cardiology procedures such as coronary angiography (CA) and percutaneous transluminal coronary angiography (PTCA) has been increased recent years. The purpose of this study was to measurement of effective dose to cardiology staffs who operate near the patient and are exposed to non-uniform radiation field due to patient scattered radiation. Materials and Methods: This...

The uveal melanoma (UM) is the most common human intraocular tumour. Simian Virus 40 (SV-40) is a small DNA tumor virus detected in some malignancies, including the cutaneous melanoma. In this study an indirect ELISA using synthetic peptides that mimic SV-40 antigens, was employed to detect antibodies against SV-40 in serum samples from UM patients. Our report indicates a significant higher pre...

Ratio of stroke volume (SV, M-mode echocardiography) to pulse pressure (PP) has been proposed as an estimate of total arterial compliance and has been shown to be related to body size, age, and heart rate in normal adults. SV/PP was estimated in 294 hypertensive patients (98 women) as a raw value by use of SV/body surface area (SVi) and by the ratio of SV/PP to the value predicted by a previous...

Mixed infection of cells with both Moloney murine leukemia virus (MoMLV) and related or heterologous viruses produces progeny pseudotype virions bearing the MoMLV genome encapsulated by the envelope of the other virus. In this study, pseudotype formation between MoMLV and the prototype parainfluenza virus Sendai virus (SV) was investigated. We report for the first time that SV infection of MoML...

Salmonella enterica sv. Typhi (S typhi), the causative organism of enteric fever which is found mainly in the developing countries, is a severe systemic disease with a worldwide frequency estimated as 12-33 million cases per year. It is transmitted not only through contaminated food and beverages, but also via a vertical mechanism during the last trimester of pregnancy. Salmonella enterica sv. ...

AIMS Transplantation of myoblast sheets is a promising therapy for enhancing cardiac function after heart failure. We have previously demonstrated that a 7-amino-acid sequence (Ser-Val-Val-Tyr-Gly-Leu-Arg) derived from osteopontin (SV peptide) induces angiogenesis. In this study, we evaluated the long-term therapeutic effects of myoblast sheets secreting SV in a rat infarction model. METHODS ...

Sodium valproate (SV), an antiepileptic drug has several mechanism of action. It inhibits voltage sensitive Na+ channels and reduces intracellular Na accumulation. These actions are similar to that of both phenytoin and carbamazepine. We have investigated the direct cardiac action of SV and its effects on ouabain-induced arrhythmia in isolated guinea-pig atria. The guinea-pig atrium was dissect...
