| This work aimed at evaluating the action of gibberellin on growth, development and production of Nicotiana tabacum L., Type Brasil-Bahia. Liquid gibberellin in doses of 0, 1.25, 3.75, 6.75 and 10.0 mL L-1 was sprayed on leaves of plants grown in greenhouse. The pelleted seeds were sowed in expanded polystyrene trays containing PlantMax®. Fifteen days after sowing (DAS), the treatments were applied. Six sprayings were made once a day, every five days. After 43 DAS, the number of leaves, length of the stem and root, dry matter of stem, leaves and roots, and leaf area were evaluated. In the field, the plants remained for 64 days and the number of total leaves, number of feasible leaves, plant height, dry matter of stem and leaves, and leaf area were... |

| Tobacco is one of the important agricultural and industrial products which plays a crucial role in economics and income of the producing countries and tobacco’s leaves are actually used commercially. In this study, the effects of two tobacco varieties K326 and 347 in three plant spacing of 30, 40, and 50 cm (with density of 33333, 25000 and 20000 plants/ha) on physical properties and weight of tobacco leaves are discussed. The results of variance analysis showed that the ¬¬¬effects of variety and plant spacing on leaf surface in 5% level were significant. Interaction effect of these two factors wasn’t significant. Also results showed that independent and interaction effects of plant spacing and different varieties of tobacco on leaf weight were significant... |

| The tobacco drying greenhouses, in general, are made without any coating that ensures thermal insulation and avoid heat losses, resulting in a large consumption of firewood during the drying of the tobacco. The study aims to develop an economically viable project to the producer, to avoid excessive heat loss through the walls and ceiling of a tobacco dryer, aimed at fuel economy, reduced drying time and reduces costs in process. For the current project, we considered changes of Brazilian theoretical mode, where we developed a thermal insulation system in a dryer, reaching satisfactory results, with a large reduction in energy losses and firewood consumption, resulting in a decrease in the costs of the proceedings in general. Thus, began for the development... |

| Corecoris dentiventris Berg, 1884 (HEM., Coreidae) represents a pest in the tobacco culture in Southern Brazil. Nymphs and adults cause the wilting and twisting of the tobacco leaves due to their sucking habit. There are very few works about this species and these are restricted to concise description of the adult morphology, records of host plants and enumeration of injuries. The present investigation aims to study the life cycle of this bug. The experiment was carried out in a tobacco culture (Virginia type, var. K 326) implanted in the experimental area of the Departamento de Fitossanidade of the Universidade Federal do Rio Grande do Sul, in Porto Alegre, RS. The life cycle was studied in field conditions, in nylon cages, from egg clusters oviposited by... |

| Special attention has emerged towards biomass smoke-induced chronic obstructive pulmonary disease (COPD), providing new knowledge for prevention and therapeutic approach of non-smoker COPD patients. However, the understanding of biomass smoke COPD is still limited and somewhat controversial. The aim of the present study was to compare COPD exclusively caused by tobacco smoking with COPD exclusively caused by environmental or occupational exposures. For this cross-sectional study, COPD patients were recruited from outpatient clinics and formed two groups: non-smoker COPD group (n=16) with exposure to biomass smoke who did not smoke cigarette and tobacco smoker COPD group (n=15) with people who did not report biomass smoke exposure. Subjects underwent... |

| To evaluate the effect of smoking habits on sleep, data from 1492 adults referred to the Sleep Institute were accessed and divided into 3 categories of smoking status: current, former and non-smokers. Categories of pack-years (<15 and ≥15) defined smoking severity. The association of smoking status and smoking severity with sleep was analyzed for sleep parameters, especially apnea and hypopnea index (AHI) ≥5, more than 5% of total sleep time (TST) spent with oxyhemoglobin saturation (SaO2) <90%, and arousal index. The arousal index was higher among current (21 ± 17) and former smokers (20 ± 17) than non-smokers (17 ± 15; P < 0.04). Former smokers had a higher percent of TST at SaO2 <90% than non-smokers (9 ± 18 vs 6 ± 13; P < 0.04). Former... |

| High Wide Ridge Soil Management is a conservation practice associated with the no-tillage, reduced tillage, and conventional tillage systems, usual in small farms in southern Brazil. Integrated with winter grain or ground cover crops such as wheat (Triticum aestivum), rye (Secale cereale), black oats (Avena strigosa) and white oats (Avena sativa), millet (Pennisetum glaucum L.), Sudan grass (Sorghum sudanense), sorghum (Sorghum spp.), mucuna (Mucuna spp.), and brachiaria (Brachiaria spp.), high wide ridge is being used for tobacco (Nicotiana tabacum), soybean (Glycine max L.), maize (Zea mays), and beans (Phaseolus vulgaris) during the spring and summer seasons. The benefits expected from this technology, related to the performance of the tobacco crop,... |

| Hepatitis C is transmitted primarily parenterally by contaminated blood and is often associated with: intravenous drug abuse, invasive procedures, blood transfusions, acupuncture, tattooing, and alcohol and tobacco use. This study aimed to quantify and evaluate the risk factors among blood donors, volunteer blood donors and replacement individuals, infected or not by the C virus. The main transmission routes of C virus were identified in 55 men and 25 women (GI) monitored by the Ambulatory Unit of the Department of Tropical Diseases, Botucatu Medical School, and in 24 men and 26 women (GII), all active blood donors at the Bauru State Hospital Transfusional Agency. Both groups were similar in: tobacco and alcohol consumption, sexual behavior, tattooing and... |
