Tylosin is a macrolide antiobiotic produced by fermentation from a culture of streptomyces fradiae. Both tylosin (C4,H77NO,7, MW: 9042) and tylosin tartrate (C47H77NO,7. C4H606, MW: 1054-3) have found wide practical use as an animal health and growth agent. They are used principally to combat dysentery in pigs and respiratory infections in poultry and may be added to the animal feed, to the dri...

Ackermann, W. W. (The University of Michigan, Ann Arbor), and D. Wahl. Programming of poliovirus inhibition of deoxyribonucleic acid synthesis in HeLa cells. J. Bacteriol. 92:1051-1054. 1966.-Deletion of arginine from a culture medium reduced the rate of deoxyribonucleic acid (DNA) synthesis in uninfected HeLa cells. The normal rate was promptly restored by addition of arginine. Deletion of arg...

Transmission properties of magnetoinductive waves propagating in two coupled one-dimensional metamaterial arrays are studied both experimentally and theoretically for the case when one of the arrays is shifted relative to the other one. Two different kinds of resonant metamaterial elements, split-pipe and spiral resonators, are investigated in the frequency bands centred at 46.2 and 586 MHz, re...

An optical parametric chirped-pulse amplifier (OPCPA) design that provides 40% pump-to-signal conversion efficiency and over-500-mJ signal energy at 1054 nm for front-end injection into a Nd:glass amplifier chain is presented. This OPCPA system is currently being built as the prototype front end for the OMEGA EP (extended performance) laser system at the University of Rochester's Laboratory for...

Este trabajo tuvo como objetivo explorar los intereses y opiniones sobre ciencia tecnología la influencia del género en estudiantes ecuatorianos. Para ello, se aplicó el cuestionario Relevancia de Educación Científica (ROSE, por sus siglas inglés) a una muestra 1054 entre 16 18 años segundo tercer bachillerato general unificado (BGU). Los resultados muestran favorables hacia tecnología, pero so...

We compared breastfeeding initiation and duration in 1054 nulliaparae randomised to bupivacaine Control epidural, Combined Spinal Epidural or Low Dose Infusion and 351 matched non-epidural comparisons. Women were interviewed after delivery and completed a postal questionnaire at 12 months. Regression analysis determined factors which independently predicted breastfeeding initiation. Breastfeedi...
