A systematic review of maternal smoking during pregnancy and fetal measurements with meta-analysis
2017
Maternal smoking during pregnancy is linked to reduced birth weight but the gestation at onset of this relationship is not certain. We present a systematic review of the literature describing associations between maternal smoking during pregnancy and ultrasound measurements of fetal size, together with an accompanying meta-analysis. Studies were selected from electronic databases (OVID, EMBASE and Google Scholar) that examined associations between maternal smoking or smoke exposure and antenatal fetal ultrasound measurements. Outcome measures were first, second or third trimester fetal measurements. There were 284 abstracts identified, 16 papers were included in the review and the meta-anal…
Polynitroxylated hemoglobin-based oxygen carrier: inhibition of free radical-induced microcirculatory dysfunction.
1999
Reactive oxygen species have been identified as key mediators of leukocyte/endothelial cell interaction under various pathological conditions and diseases such as ischemia/reperfusion injury, inflammation, and after exposure to cigarette smoke. Consequently, antioxidants have been shown to successfully prevent the sequelae of these conditions, ranging from tissue infarction to atherogenesis. In this study we investigated whether, via its established superoxide dismutase-like activity, a novel polynitroxyl hemoglobin-based oxygen carrier (PNH), could affect the stimulation of leukocyte rolling and adhesion to endothelial cells in response to cigarette smoke. Using the dorsal skin fold chambe…
Fire safety investigation for road tunnel ventilation systems – An overview
2014
Abstract In recent years, research activities about fire events in tunnel have received a significant impulse, especially after several accidents. The Computational Fluid Dynamic (CFD) has a fundamental role about. Researchers have spent resources on various topics involving numerical tools as the performance of a ventilation system, the influence of this on the air flow motion in the tunnel or the methods for fire schematization, fire-induced smoke characterization, turbulence models, etc. One of the main phenomena to consider for the safety when a fire occurs in a tunnel is the possibility of the fire-induced smoke to rise the tunnel (backlayering). A well-designed ventilation system shal…
Mosses as Biomonitor of Air Pollution with Analytes Originating from Tobacco Smoke
2018
Abstract The aim of the carried out research was the assessment of the possibility to use a popular bioindicator - Pleurozium schreberi mosses as a biosensor of the air pollution in living quarters with the analytes originating from tobacco smoke. The moss bag method of active biomonitoring, popular in environmental studies, was applied; the method is based on exposing mosses collected in clean areas in the locations polluted with, for example, heavy metals. However, this experiment involved exposing mosses in living quarters, in which approximately 10 cigarettes were smoked daily (first room - kitchen). For the purpose of comparison, moss samples were also placed in another room (bedroom),…
Effects of tobacco smoke on indoor air quality: the use of mosses in biomonitoring.
2020
This research was carried out to assess the possibility of using Pleurozium schreberi mosses as bioindicators of atmospheric aerosol pollution in living quarters (kitchen and bedroom), with metals originating from tobacco smoke from various types of cigarettes: conventional cigarettes, e-cigarettes and heated tobacco products. The moss-bag method of active biomonitoring was used. The mosses were exposed in these indoor spaces for three months and, after the exposition period, their analytes – Ni, Cu, Zn, Cd and Pb – were determined using flame atomic absorption spectrometry (F-AAS). Results were interpreted using the relative accumulation factors (RAF), coefficients of variation (CV) and th…

Blood rheology at term in normal pregnancy and in patients with adverse outcome events.
2009
Plasma volume expansion of more than 1.5 1 and sustainable activation of the hemostatic system that results in a steady rise of the fibrinogen/fibrin turnover are contemporary physiological events during normal pregnancy. In contrast, adverse outcome of pregnancy i.e. pre-eclampsia commonly coincide with hemo concentration and over activation of blood coagulation both of which alter blood rheology. On the basis of 4,985 consecutively recorded singleton pregnancies values range of blood rheological parameters in women with normal and complicated outcome of pregnancy at the time of their delivery were compared. Plasma viscosity (pv) was determined using KSPV 1 Fresenius and RBC aggregation (s…
Extracorporeal Shock Waves Increase Markers of Cellular Proliferation in Bronchial Epithelium and in Primary Bronchial Fibroblasts of COPD Patients
2020
Chronic obstructive pulmonary disease (COPD) is due to structural changes and narrowing of small airways and parenchymal destruction (loss of the alveolar attachment as a result of pulmonary emphysema), which all lead to airflow limitation. Extracorporeal shock waves (ESW) increase cell proliferation and differentiation of connective tissue fibroblasts. To date no studies are available on ESW treatment of human bronchial fibroblasts and epithelial cells from COPD and control subjects. We obtained primary bronchial fibroblasts from bronchial biopsies of 3 patients with mild/moderate COPD and 3 control smokers with normal lung function. 16HBE cells were also studied. Cells were treated with a…
The role of traditional Erica arborea L. management practices in maintaining northeastern Sicily’s cultural landscape
2007
The tree heath (Erica arborea L.), a small evergreen tree found in the Mediterranean region and parts of Eastern and Central Africa, produces lignotubers that are highly valued for making smoking pipes. The Peloritani Mountains of northeastern Sicily are historically one of the most important areas in Italy for the production of these high quality lignotubers, known as briar root wood. In the past, tree heath shrublands were also an important source of charcoal. Erica arborea utilisation has declined dramatically during the past century, mostly due to the decreasing demand for smoking pipes, as well as the increasing frequency of wildfires and large-scale afforestation activities in this re…
Fumo, alcol e salute orale
2013
Obiettivi. Il fumo di sigaretta, seconda causa di morte nel mondo, e l’abuso di alcol, una delle principali cause di mortalità e morbilità, costituiscono importanti fattori di rischio per le patologie del cavo orale. Scopo di questo lavoro è presentare gli effetti del fumo di sigaretta e dell’abuso di alcol sulla salute orale. Sono inoltre illustrate le modalità di realizzazione di interventi di cessazione dell’abitudine al fumo nell’ambito dell’attività professionale dell’odontoiatra e dell’igienista dentale. Materiali e metodi. Attraverso la banca dati Medline/Pubmed sono stati selezionati i lavori originali, le revisioni della letteratura e le linee guida in lingua inglese e in italiano …
