during the epidemiological research of zoonoses, the authors have studied the rabies of wild animals : fox. for the scro lo-uical tests. the blood . was taken by heart puncture of foxes. 193 specimens were tested and 26 (13. 5%) o r the foxes had neut ralizing antibody in their blood. this study confirms that during the rabies epizooty. the vulpin population, may contract a non-fatal disease an...

A crossbreeding experiment between 4 Spanish maternal lines of rabbits was performed to estimate crossbreeding effects on litter size components. The experiment was designed as a complete diallel cross involving 4 lines selected for litter size at weaning (A, V, H, and LP [L]) and their 12 simple crosses. Does from these 16 genetic groups were distributed among 4 Spanish farms, but only V line ...

r l h b w Inappropriate sensing of atrial and ventricular electrical ctivity is a common cause of pacemaker malfunction and is outinely screened for during pacemaker clinic visits. Unersensing is typically resolved by programming the voltage evel required for sensing to lower, ie, more sensitive, levls. This report discusses a situation in which, paradoxially, undersensing was resolved by progr...

In this paper we introduce an extension of the Probably Approximately Correct (PAC) learning model to study the problem of learning inclusion hierarchies of concepts (sometimes called is-a hierarchies) from random examples. Using only the hypothesis representations output over many different runs of a learning algorithm, we wish to reconstruct the partial order (with respect to generality) amon...

The DNA templates containing immediate early (IE) genes of human cytomegalovirus (CMV) were transcribed in vitro by using a HeLa cell extract. When IE region 1, 2, and 3 were used, transcription was detected qualitatively only from IE region 1. Transcription was detected with DNA representing IE region 2 when the IE region 1 promoter was not present. DNA sequence analysis of the upstream regula...

TOPIC: Cardiovascular Disease TYPE: Medical Student/Resident Case Reports INTRODUCTION: Infective endocarditis (IE) is a rare infection associated with high morbidity and mortality. Left-sided IE cases continue to outweigh the number of right-sided (RSIE) cases. 90% RSIE involve tricuspid valve (1). Staphylococcus species remains most prevalent cause all IE(2). Imaging choice for transthoracic ...

Introduction Dynamic C NMR spectroscopy combined with C label administration has been used to study brain metabolism non-invasively. N-acetyl aspartate (NAA) metabolism has been considered to be slow [1-3] and to have a similar turnover time as glycogen [3]. Most studies employed direct C detection to measure C label in NAA, with an additional external reference to calculate the isotopic enrich...

BACKGROUND The clinical implications of a negative multiplane transesophageal echocardiography (TEE) have not yet been reported. We aim to determine the negative predictive value (NPV) of a negative multiplane TEE in patients with suspected infective endocarditis (IE). METHODS AND RESULTS We identified 83 consecutive patients with suspected IE and negative multiplane TEE from our echocardiogr...
