Phonation threshold pressure (PTP) is frequently used for characterizing vocal fold vibration properties. However, because of the very low pressures, it is often difficult to measure PTP with acceptable accuracy. This investigation analyses an alternative pressure, the collision threshold pressure (CTP), defined as the lowest pressure required to initiate vocal fold collision. Fourteen amateur ...

BACKGROUND/OBJECTIVE Clinical evidence indicates that cerebral ischemia (CI) and a pathological factor of Alzheimer's disease, the β-amyloid (Aβ) protein, can increase the rate of cognitive impairment in the ageing population. Using the CT Perfusion (CTP) functional imaging, we sought to investigate the interaction between CI and the Aβ protein on cerebral hemodynamics. METHODS A previously e...

PURPOSE The purpose of this meta-analysis was to evaluate the sensitivity and specificity of computed tomography perfusion (CTP) in diagnosing acute ischemic stroke in patients presenting to the emergency department with stroke-like symptoms. METHODS Medline, Cochrane, EMBASE, and Google Scholar databases were searched until November 5, 2014 using the following terms: magnetic resonance imagi...

Routing protocols for ad-hoc networks, e.g., the Collection Tree Protocol (CTP), are designed with simple node-local behaviour, but are deployed on testbeds with uncontrollable physical topology; exhaustively verifying the protocol on all possible topologies at design time is not tractable. We obtain topological insights on CTP performance, to answer the question: Which topological patterns cau...

Cytosine arabinoside (Ara-C) is the most effective agent in the treatment of acute myelogenous leukemia. This agent incorporates in leukemic cell DNA, and the extent of this incorporation correlates with loss of clonogenic survival. The incorporated Ara-C residue behaves as a relative DNA chain terminator, and the extent of (Ara-C)DNA formation correlates with inhibition of DNA synthesis. The i...

AIM Collagen tripeptide (CTP) is a functional food with a high content of Gly-X-Y tripeptides derived from collagen. The objective of this study was to evaluate the effect of CTP administration on the development of atherosclerosis in healthy individuals. METHODS The present study was conducted in the form of an open-label, single-dose trial for 6 months. All subjects ingested CTP twice daily...

Background: Chronic liver disease (CLD) often results in fatal complications. Child-Turcotte-Pugh (CTP) score is the earliest predictor of mortality but Model for End-Stage Liver Disease (MELD) more objective. Studies showed platelet-lymphocyte ratio (PLR) and neutrophil-lymphocyte (NLR) could become predictors chronic disease. We aimed to investigate NLR PLR as early CLD, comparison with CTP M...

Extreme rainfall (ER) in Indonesia frequently leads to floods and landslides, disrupting economic activity impacting human lives. Here, we investigate ER variability association with climate teleconnection patterns (CTP) including the El Niño Southern Oscillation (ENSO), Indian Ocean Dipole (IOD), Madden-Julian (MJO), using extreme value analysis based on daily data from 32 stations for 30 year...
