The results of the analysis of data taken in the continuation of a previously reported search1 for highly ionizing particles at PEP are presented. These data were taken in the period from October 1981 to June 1983. Assemblies consisting of Lexan and CR-39 plastic track detectors were exposed in two runs to integrated luminosities of 30 X 1O36 cm-2 and 150 X 10% crnw2% The search was sensitive t...

BACKGROUND In studies generally involving short follow-up, exercise echocardiography has been shown to predict composite end points. We sought to study the prediction of mortality with this test and to devise a strategy for combination with standard exercise testing. METHODS AND RESULTS Clinical, exercise testing, and echocardiographic data were collected in 5375 patients (aged 54+/-14 years,...

Apidaecins, short proline-arginine-rich peptides from insects, are highly bactericidal through a mechanism that includes stereoselective elements but is completely devoid of any pore-forming activity. The spectrum of antibacterial activity, always limited to Gram-negatives, is further dependent on a small number of variable residues and can be manipulated. We show here that mutations in the evo...

Radon contributes with more than 50% to the dose equivalent to the public coming from natural sources, and is a major risk factor for lung cancer occurrence (10–14%, in Europe, p.a.) which should be investigated. Insufficient data on radon levels exist for Romania up to now and further extensive surveys are needed. The paper presents a series of in-situ indoor radon data in various locations in...

Particle intensity, dose equivalent and absorbed dose have been measured on board the space shuttles during their visit to the International Space Station (ISS) on STS-108 and STS-112. The dose estimates are based on very accurate measurements of recoils produced in CR-39 by cosmic ray primary and secondary protons and heavier nuclei and by secondary neutrons. The corresponding LET spectra were...
