DNA single strand break analysis in mononuclear blood cells of petrol pump attendants

1995

DNA single strand breaks, including DNA adducts that lead to alkali-labile sites, were measured in peripheral mononuclear blood cells of 35 petrol pump attendants by alkaline filter elution. Blood samples from petrol pump attendants were taken on Monday and Friday. Additionally, DNA single strand breaks of smoking and non-smoking control persons were examined. For the smoking (n = 12) and the non-smoking controls (n = 20) a mean normalized elution rate of 1.49 +/- 0.52 (mean value +/- 95% confidence interval) and 1.32 +/- 0.28, respectively, was obtained. The difference between smoking and non-smoking controls was not statistically significant (U test). An increase in DNA single strand brea…

Cigarette Smoking Status at Diagnosis and Recurrence in Intermediate-risk Nonemuscle-invasive Bladder Carcinoma

2013

Objective To study the effect of smoking status at diagnosis on recurrence in intermediate-risk non–muscle-invasive bladder carcinoma treated by transurethral resection (TUR) of the bladder and early intravesical chemotherapy. Methods Tumor characteristics and smoking status were recorded in 395 patients entered in a randomized multicenter trial comparing 2 different schedules of early intravesical chemotherapy. All patients received intravesical epirubicin (80 mg/50 mL) within 6 hours after TUR, followed by 5 more weekly instillations with (arm B) or without (arm A) monthly instillations for 1 year. Smoking habit was investigated at diagnosis through a structured questionnaire. Multivariat…

A case-control study on cigarette, alcohol, and coffee consumption preceding Parkinson's disease

2003

<i>Objective:</i> To investigate the association between cigarette smoking, alcohol drinking, coffee consumption and Parkinson’s disease (PD). <i>Methods:</i> We selected subjects affected by idiopathic PD, with a Mini-Mental State Examination of ≧24, and controls matched 1 to 1 with cases by age (± 2 years) and sex. Controls were randomly selected from the resident list of the same municipality of residence of the cases. We assessed cigarette smoking, alcohol drinking, and coffee consumption preceding the onset of PD or the corresponding time for controls using a structured questionnaire, which also evaluated the duration and dose of exposure. Using conditional logi…

Variations in maximal oxygen intake with physical activity in middle-aged men.

1970

Data on maximal exercise performance are presented for normal middle-aged men free of cardiovascular disease. Maximal oxygen intake, oxygen pulse, heart rate, and lactate levels all decrease with increasing age. Physical activity defined by habitual running of any amount had a highly significant effect on maximal oxygen consumption. The enhanced effect of physical activity was found equivalent to nearly 10 years of age effect on maximal aerobic capacity. Multivariate analysis revealed significant association between maximal oxygen intake and several coronary risk factors; specifically, physical activity, vital capacity, cigarette smoking, and body weight. Notably lacking in significance wer…

Smoking, diabetes, blood hypertension: possible etiologic role for Peyronie’s disease? Analysis in 279 patients with a control group in Sicily

2015

Objective: To assess the proportion of patients with Peyronie’s Disease (PD) and the possible association with its potential risk factors in the general population of the central and western Sicily in our weekly andrological outpatient clinic. Materials and methods: We recruited a sample of 279 consecutive patients consulting our andrological outpatient clinic. Two arms were created: the first one composed by PD patients (men with symptoms suggestive for PD), the second one composed by patients with other andrological diseases (control arm). For each patient we evaluated the age, cigarette smoking, diabetes, blood hypertension and erectile function. In the PD arm we administered validated q…

Evaluación del grado de queratinización y el recuento de AgNORs en citología exfoliativa de mucosa oral normal de individuos fumadores y no fumadores

2004

Objetivos. En individuos fumadores con mucosa oral clínicamente sana, se han observado cambios citológicos como una mayor queratinización, existiendo también reportes de un mayor grado de actividad nucleolar. En estos estudios, las células para frotis se han obtenido por medio de espátula de madera. Nuestro objetivo es evaluar la profundidad de muestras citológicas de mucosa oral obtenidas con cepillo para frotis (endobrush) y comparar el grado de queratinización y la actividad nucleolar en pacientes fumadores y no fumadores. Diseño del estudio. Se obtuvieron frotis de mucosa oral de borde de lengua clínicamente normal de 30 individuos fumadores y 30 no fumadores, utilizando espátula de mad…

Darbinieku darba grafika izveide, lietojot lineāro programmēšanu

2018

Darbinieku darba grafika plānošanai ir sarežģīts process, kura mērķis ir atrast optimālo darba grafika veidu, kas apmierinātu ne tikai uzņēmuma vajadzības, bet arī pašu darbinieku vēlmes attiecībā uz darba laiku. Bakalaura darbā tiek pētīts kā var atvieglot darba grafika izveidi, izmatojot lineāro programmēšanu. Darbā tiek apskatīti literatūrā esošie darba grafika plānošanas modeļi (Danciga modelis, Bečtolda un Džeikobsa modelis, Aikina modelis un Tomsona modelis), kas tika salīdzināti savā starpā un ilustrēti ar piemēriem.

Optimising experimental research in respiratory diseases: an ERS statement

2018

Experimental models are critical for the understanding of lung health and disease and are indispensable for drug development. However, the pathogenetic and clinical relevance of the models is often unclear. Further, the use of animals in biomedical research is controversial from an ethical perspective.The objective of this task force was to issue a statement with research recommendations about lung disease models by facilitating in-depth discussions between respiratory scientists, and to provide an overview of the literature on the available models. Focus was put on their specific benefits and limitations. This will result in more efficient use of resources and greater reduction in the numb…

EFFECT OF ANNEALING PROCESS ON CIGS FILMS PREPARED BY ONE-STEP ELECTRODEPOSITION

2013

The symbiosis between Nicotiana tabacum and the endomycorrhizal fungus Funneliformis mosseae increases the plant glutathione level and decreases leaf…

2015

Over time, anthropogenic activities have led to severe cadmium (Cd) and arsenic (As) pollution in several environments. Plants inhabiting metal(loid)-contaminated areas should be able to sequester and detoxify these toxic elements as soon as they enter roots and leaves. We postulated here that an important role in protecting plants from excessive metal(loid) accumulation and toxicity might be played by arbuscular mycorrhizal (AM) fungi. In fact, human exploitation of plant material derived from Cd- and As-polluted environments may lead to a noxious intake of these toxic elements; in particular, a possible source of Cd and As for humans is given by cigarette and cigar smoke. We investigated …
