We have read with great interest the article by Castagnaro et al (October 1999),1 reporting a significant drop in oxygen saturation in the absence of an equivalent drop in FEV1 during sputum induction. This, however, has not been our experience. Although we agree that FEV1 may fall in asthmatics, COPD patients,2 and normal volunteers,3 we have not seen significant changes in oxygen saturation. ...

OBJECTIVE To verify the functionality through muscle grip strength in animals with obesity induced by monosodium glutamate (MSG) and in control animals, which suffered compression of the right median nerve, and treated with swimming with overload. METHODS During the first five days of life, neonatal Wistar rats received subcutaneous injections of MSG. The control group received a hypertonic s...

Urinary bladder cancer (UBC) is dominantly the cancer of the elderly occurring primarily in the 6h, 7!h and 81h decade of life. The aim of this study was to evaluate diagnostic accuracy of ultrasound T-staging (UTS) of UBC in dhe group of elderly patients. In 152 elderly patients referred to transabdominal ultrasound examination in two different facilities (76 each) due to various symptoms (pri...

This paper shows how an HMM-based speech synthesizer in Basque language has been built using HTS and AhoTTS (the TTS system developed at Aholab). The resulting system, which is being used only for research purposes at present, has a highly satisfactory performance.

HTS materials are known to produce intermodulation and other nonlinear effects, and this may restrict their use in wireless communication systems. While significant efforts are being done to measure and characterize nonlinear properties of HTS materials, there are very few works that relate these properties to system parameters. In this work we attempt to bridge this gap by using Harmonic Balan...

High-throughput screening (HTS) has played an integral role in the development of small molecule modulators of biological processes. These screens are typically developed for enzymes (such as kinases or proteases) or extracellular receptors, two classes of targets with well-established colorimetric or fluorimetric activity assays. In contrast, methods for detection of protein-protein interactio...

BACKGROUND When learning objectives do not specifically dictate the use of one simulation modality over another, we sought to answer the question of which modality is preferred. We also assessed the impact of debriefing, and the frequency of participants asserting their leadership, as well as self-reported comfort and competence, and the ability to generate differential diagnoses when either a ...

Although echinococcal disease of the liver is common in some parts of the world, it is rarely seen in the United States. Even from endemic areas, few reports deal with its treatment during pregnancy. A 25 year old 18 week pregnant Italian woman presented with pruritus and right upper quadrant pain. Ultrasound revealed a cystic lesion in the left lobe of the liver. The cyst was treated by operat...

We have used the anorexia shown by rats given hypertonic saline to drink to investigate central mechanisms that can inhibit feeding. Rats dehydrated in this manner for 3 or 5 days showed a severe attenuation of the compensatory feeding observed after an overnight fast compared with control euhydrated rats or rats whose food was restricted to match the intake of anorexic rats. Food intake after ...

This work presents the use of Harmonic Balance to simulate the nonlinear behavior of HTS transmission lines. Good agreement with theoretical cross-checks is found We also show the use of this algorithm to fit the model of HTS lines from experimental measurements. We illustrate this by fitting several types of experimental data, and discuss how to avoid ambiguity in this fitting. Non-linear elem...
