The purpose of this study was to evaluate quantitatively the parameters of the video laryngostroboscopy (VLS) and determine correlations between the VLS parameters and acoustic vocal function parameters. Digital VLS recordings, acoustic voice assessment, calculation of dysphonia severity index (DSI) and registration of voice range profile (VRP) were performed for 206 individuals: 50 healthy and...

The problem of determining visibility locations (VLs) on/inside a domain bounded by a planar C1-continuous curve (without vertices), such that entire domain is covered, is discussed in this paper. The curved boundary has been used without being approximated into lines or polygons. Initially, a few observations regarding the VLs for a curved boundary have been made. It is proposed that the set o...

The vertical launch system (VLS) is the U.S. Navy’s premier missile launch system for surface ships. The VLS is modular, and its configuration is tailored to the individual ship. Depending on ship type or class, ship configurations have one or two launching systems. A ship can carry between 61 and 121 missiles. At the end of fiscal year 1993, about 73 systems were deployed on 46 ships; these nu...

valois (vls) was identified as a posterior group gene in the initial screens for Drosophila maternal-effect lethal mutations. Despite its early genetic identification, it has not been characterized at the molecular level until now. We show that vls encodes a divergent WD domain protein and that the three available EMS-induced point mutations cause premature stop codons in the vls ORF. We have g...

We develop a clinical visible-light spectroscopy (VLS) tissue oximeter. Unlike currently approved near-infrared spectroscopy (NIRS) or pulse oximetry (SpO2%), VLS relies on locally absorbed, shallow-penetrating visible light (475 to 625 nm) for the monitoring of microvascular hemoglobin oxygen saturation (StO2%), allowing incorporation into therapeutic catheters and probes. A range of probes is...

The rotavirus NSP5 protein directs the formation of viroplasm-like structures (VLS) and is required for viroplasm formation within infected cells. In this report, we have defined signals within the C-terminal 21 amino acids of NSP5 that are required for VLS formation and that direct the insolubility and hyperphosphorylation of NSP5. Deleting C-terminal residues of NSP5 dramatically increased th...

OBJECTIVE Currently the detection of renal vascular lesions (VLS) mainly depends on biopsy examination, and lacks surrogate biomarkers for clinical dynamic evaluation. The aim of this study is to find the correlation between numbers of circulating endothelial cells (CECs) and renal VLS in lupus nephritis (LN). METHODS Thirty LN patients with VLS and 30 LN patients without VLS were recruited. ...

OBJECTIVE The purpose of this study was to evaluate quantitatively the basic parameters of the video laryngostroboscopy (VLS) and determine the sensitivity and specificity of these parameters discriminating healthy and pathological voice classes. METHODS Digital VLS recordings were performed for 159 individuals: 26 healthy and 133 patients. VLS variables (glottal closure, regularity, mucosal ...

INTRODUCTION This study aimed to evaluate the presence of Aedes aegypti in breeding sites located in vacant lots (VLs) and determine the effectiveness of VL cleaning to reduce insect foci. METHODS Two types of VLs were sampled, the experimental VL, which was cleaned monthly, and the control VL, which was not cleaned. RESULTS Monthly cleaning of VLs reduced the abundance of immature forms of...
