CORESTA Meeting, Smoke Science/Product Technology, Freiburg, 2003, STPOST 02 Removal of free radicals in mainstream cigarette smoke by filters including antioxidant rosemary extract: quantification by a new and robust LC-MS/MS method EMAMI I.; MASSELOT D.; VANDOOLAEGHE P.; LE GAC S.; ROLANDO C. Biosynthec, Paris, France The presence of free radicals in cigarette smoke was demonstrated more than 40 years ago by freezing of mainstream smoke and analyzing the resulting solid using ESR techniques. 1 Free radicals play a central role in ageing diseases like cancer,...
CORESTA Congress, New Orleans, 2002, STPOST 13 A new and efficient method for detecting free radicals by LC-MS/MS. Application to the optimization of a cigarette filter which remove free radicals in cigarette smoke MASSELOT D.; EMAMI I.; ROLANDO C.; LE GAC S. Biosynthec, Paris, France Free radicals are involved in a wide variety of ageing diseases such as cancer, cardiovascular diseases and arteriosclerosis: these are known effects that have driven us to want to radically decrease the free radical contents in cigarette smoke....
Bull. Spec. CORESTA Congress, Lisbon, 2000, p. 167, ST22 New filters based on natural polyphenols scavenge efficiently free-radicals in cigarette smoke EMAMI I.; ALEXANDROV K.; VEZINC H.; ROLANDO C. Biosynthec, Paris, France Free radicals in smoke are believed to be major contributors to the initiation and promotion of various forms of cancer, presumably by increasing the oxidative stress in lungs. We will describe a new filter based on natural polyphenols which scavenge...
Bull. Spec. CORESTA Congress, Brighton, 1998, p. 94, A8 Effect of nitrogen on photosynthetic characteristics of Virginia tobacco (Nicotiana tabacum L.) COVARELLI L. Istituto di Agronomia Generale, Perugia, Italy. A field experimental research study was carried out in 1996 in Central Italy in order to evaluate the effect of N-fertilisation rate (0, 60, 120 kg ha-1 N) on leaf net assimilation rate by Virginia tobacco (cv. K394). Leaf CO2 assimilation...
Bull. Spec. CORESTA Congress, Yokohama, 1996, p. 112, A5 Field experimental studies about chemical weed control in Virginia tobacco COVARELLI G.; COVARELLI L. Istituto di Agronomia Generale, Perugia, Italy. A field research-study was carried out from 1994 to 1995, in order to evaluate some possible options for chemical weed control in Virginia Tobacco (McNair 944). Three experimental trials were conducted in Central Italy, which is one of the most...
Bull. Spec. CORESTA Congress, Yokohama, 1996, p. 147, APOST9 Chemical control of lateral suckers in Virginia tobacco, using new contact substances and reduced rates of maleic hydrazide COVARELLI G. Istituto di Agronomia Generale, Perugia, Italy. A field study was carried out from 1994 to 1995 in Central Italy to evaluate the efficacy of butralin, a newly introduced chemical for the control of lateral suckers in tobacco. Furthermore, the possibility of reducing the usage rate of Maleic...
Bull. Spec. CORESTA Congress, Jerez de la Frontera, 1992, p. 70, AP24, ISSN.0525-6240 Competition between barnyardgrass (Echinochloa crus-galli L. Beauv.) and Virginia tobacco : effects on growth, nitrogen uptake and yield TEI F.; COVARELLI G. Istituto di Agronomia Generale, Perugia, Italy. Barnyardgrass (Echinochloa crus-galli L. Beauv.) is one of the most important annual grass weeds in Virginia tobacco in Italy. This study was designed to research the effect of the duration of competition on growth, nitrogen uptake and crop yield....
CORESTA Meeting, Agronomy/Phytopathology, Cesme, 1989, A 08 Effect of ammonium and nitrate nitrogen on yield and quality of Virginia tobacco COVARELLI G. Istituto di Agronomia Generale, Perugia, Italy. Field experiments were carried out in central Italy in 1986 and 1987 to evaluate the effects of ammonium and nitrate nitrogen on yield and quality of Virginia tobacco. 50 kg N/ha were supplied in different proportions of ammonium and nitrate...
Bull. Spec. CORESTA Congress, Guangzhou 1988, p. 84, A-2 Direct seeding of Virginia tobacco on clay-loam soil in central Italy COVARELLI G.; FANTOZZI P. Istituto di Agronomia Generale, Perugia, Italy. Traditional tobacco cultivation starts with transplanting of young plants from a nursery into open fields. This operation, linked to the cool spring weather in many countries, is very costly if we are dealing with tobacco for protein. In fact, the...
