Abstract: lung cancer is a multifactorial disease. hereditary, genetic, and environmental factors interact in its genesis. the principal risk factor for lung cancer is smoking. however, the workplace provides an environment in which there is a risk of exposure to carcinogens. the international agency for research on cancer currently lists 19 substances/work situations/occupations that have been proven to be associated with lung cancer (group 1). thorough occupational history taking is not widely practiced in patients with lung cancer, which has a negative impact on the investigation of causality and, consequently, on the identification of cases of occupational cancer. the objectives of this review were to list the agents that are recognized as causes of lung cancer, to discuss the contribution of occupation to the development of the disease, to cite national studies on the subject, and to propose a list of procedures that are essential to the appropriate investigation of causality between lung cancer and occupation.

Abstract: context: lead poisoning due to retained gunshot bullets is a well-known clinical problem that is fairly frequently described in the literature. the risk factors for this occurrence relate mainly to whether the lead bullet is in contact with the joint fluid or cerebrospinal fluid (csf). the treatment for these cases entails chelation therapy while symptoms are shown and definitive surgical removal of the bullet as a potential source of lead. the aim of this paper is to describe a clinical case of lead poisoning due to a retained gunshot bullet in contact with csf. case report: a 42-year-old male was hit by gunshot bullets during a holdup, and one of them was retained in the spinal cord. six years later, he developed intense low back pain and underwent laminectomy. nine years later, he then underwent arthrodesis on l5-s1, but he developed intense abdominal pain after the surgical procedure. for five years, he was treated with calcium versenate in five-day cycles, with a good response. the chelation therapy cycles showed great efficacy during symptomatic periods, thus reducing the symptoms and signs of poisoning and promoting great amounts of lead excretion, thereby reducing the total lead burden responsible for the symptoms. fortunately, over the last four years, the symptoms have improved and the urine levels of aminolevulinic acid (ala) have declined, to reach complete normalization. this shows that a healing process is probably taking place on the spinal wound, thereby isolating the bullet fragments from csf contact.

Abstract: objective: to assess possible alterations in the tidal volume and peak inspiratory pressure delivered by seven models of manually operated self-inflating resuscitation bags as a function of the oxygen supply rate used. methods: the resuscitation bags tested were the following: oxigel, models a and b; ce reanimadores; protecsolutions; missouri; axmed; and narcosul. for the measurements, a wall oxygen flow meter, a flow meter/respirometer, a resuscitation bag, a sensor (tracer 5 unit), and a test lung were connected. in addition, the tracer 5 unit was connected to a notebook computer. oxygen supply rates of 1, 5, 10, and 15 l/min were used. results: the tidal volume delivered by the oxigel model a resuscitation bag when receiving oxygen at a rate of 15 l/min was approximately 99% greater than that delivered when receiving oxygen at a rate of 1 l/min. similarly, peak inspiratory pressure was approximately 155% greater. under the same conditions, the tidal volume delivered by the narcosul resuscitation bag was 48% greater, and peak inspiratory pressure was 105% greater. the remaining resuscitation bags tested showed no significant alterations in the tidal volume or peak inspiratory pressure delivered. conclusions: under the resistance and compliance conditions used, the resuscitation bags in which the oxygen inflow is directly to the interior of the bag had the patient valve stuck at the inspiratory position when receiving oxygen at a rate > 5 l/min, significantly increasing the tidal volume and peak inspiratory pressure delivered. this did not occur with the resuscitation bags in which the oxygen inflow is directed to the exterior of the bag.

Abstract: O presente estudo empregou o procedimento de envelhecimento artificial, submetendo sementes por 96 horas à 42° C e 100% de UR para compará-las com sementes estocadas por 5, 10 e 15 anos e utilizou eletroforese de isoenzimas e atividade de peroxidase por método colorimétrico. Houve um decréscimo significante na germina o das sementes envelhecidas artificialmente, quando comparadas com as sementes estocadas. A atividade da peroxidase foi baixa, porém houve uma curva ascendente que acompanhou a idade das sementes. Observou-se um aumento nas atividades da malato desidrogenase e a-esterase 2 e 3 e uma diminui o acentuada para a-esterase 1 e baixa para a fosfatase ácida. Os resultados acompanharam o aumento do tempo de estocagem das sementes e do estresse que ocorre por causa das condi es de temperatura e umidade empregadas no processo de envelhecimento artificial.

Abstract: of all the processes used in foliar evaluation, sampling is currently still the most subject to error. to corroborate this, the present study aimed to determine the size of foliar samples and error variation of samples collected from mango tree leaves. the study used a completely randomized design with six repetitions and four different treatments which consisted of a leaf from each of the cardinal points from 5, 10, 20 and 40 different trees. mean variation, mean standard error, mean confidence interval and error percentage compared to mean values were calculated based on level of nutrients. results were calculated by using the semi-amplitude of the interval of confidence expressed as mean percentages. obtained results led to the conclusion that the chemical evaluation of macro-nutrients from 10 mango plants would be sufficient for assessment. however, for assessment of micro-nutrients, the sampling of 20 plants would be necessary, and, when considering fe, a total of 30 plants should be used.
