Distilled water was canned in two types of Mexican cans: for tuna and for jalapeno peppers. Results showed that there is an effect of heat treatment on migration of both compounds. Storage time did not show any effect in BPA migration from tuna cans. There was an effect of storage time on BPA migration from jalapeno pepper cans. Results for BADGE migration were affected by its susceptibility to hydrolyze in aqueous simulants. BADGE concentration decreased, or was not detected, during storage in both types of cans. Migration levels for BPA and BADGE were within 0.6-83.4 and <0.25-4.3 microg/kg, respectively. Both were below European and Mercosur legislation limits. Other migrating compounds were detected, although no identification was performed.

The task was to test whether lead, mercury, copper, zinc and benzene in environmentally relevant concentrations influence porphyrin synthesis of cells. The model used was the permanent epithelial larynx carcinoma cell line HEp-2, which was stimulated to synthesize porphyrins by adding Î´-amino-levulinic acid (Î´-ALA) in excess. 8- to 4-carboxyporphyrins and protoporphyrin IX were measured both in the cells and in the culture medium by means of high performance liquid cromatography (HPLC). The following pollutant effects were found: lead: extracellular increase of hexacarboxyporphyrin and intracellular decrease of heptacarboxy- and copro-porphyrin; mercury: extracellular decrease of heptacarboxyporphyrin and intracellular increase of coproporphyrin; copper: extracellular decrease of uro-, coproporphyrin and protoporphyrin IX, extracellular increase of heptacarboxyporphyrin and intracellular decrease of uro-, heptacarboxy- and coproporphyrin; zinc: extracellular increase of coproporphyrin; benzene: a tendency to extracellular increase of hexacarboxyporphyrin. The main result is the decrease in the concentrations of porphyrins caused by copper. This result is possibly linked to gastro-intestinal diseases among children due to drinking water from copper water pipes.

MATERIALS AND METHODS: Twenty-four disk-shaped specimens were fabricated for each resin material and randomly divided into three groups (n = 8). The specimens were immersed in tea, coffee or deionized water, respectively, for 7 days. Each group was then equally divided into two sub-groups (n = 4), which were subjected to two in-office bleaching agents (BEYOND and Opalescence Boost), respectively. The color of the specimens was measured by a spectrophotometer at baseline, after staining and after bleaching. The color differences (DeltaE values) between baseline and after treatments were calculated. RESULTS: Statistical analysis indicated that the staining solution had significant influence on the color change of resin composites tested (p 2.0). There was no statistically significant difference between BEYOND and Opalescence Boost in stains removal from discolored resins (p = 0.550). The color changes in DeltaE value between baseline and after bleaching were less than 2.0 for all resin composite groups. CONCLUSIONS: Tea solution produces severe discoloration of three resin composites tested. The two in-office bleaching agents can effectively remove the stains from two ceromers and one direct composite resin tested in this study.

Six volunteers participated in four diving protocols, with 2 wk of recovery between dives. On dive 1, before diving, all divers breathed normally for 20 min at the surface of the sea (Air). On dive 2, before diving, all divers breathed 100% oxygen for 20 min at the surface of the sea [normobaric oxygenation (NBO)]. On dive 3, before diving, all divers breathed 100% O2 for 20 min at 6 m of seawater [msw; hyperbaric oxygenation (HBO) 1.6 atmospheres absolute (ATA)]. On dive 4, before diving, all divers breathed 100% O2 for 20 min at 12 msw (HBO 2.2 ATA). Then they dove to 30 msw (4 ATA) for 20 min breathing air from scuba. After each dive, blood samples were collected as soon as the divers surfaced. Bubbles were measured at 20 and 50 min after decompression and converted to bubble count estimate (BCE) and numeric bubble grade (NBG). BCE and NBG were significantly lower in NBO than in Air [0.142+/-0.034 vs. 0.191+/-0.066 (P<0.05) and 1.61+/-0.25 vs. 1.89+/-0.31 (P<0.05), respectively] at 20 min, but not at 50 min. HBO at 1.6 ATA and 2.2 ATA has a similar significant effect of reducing BCE and NBG. BCE was 0.067+/-0.026 and 0.040+/-0.018 at 20 min and 0.030+/-0.022 and 0.020+/-0.020 at 50 min. NBG was 1.11+/-0.17 and 0.92+/-0.16 at 20 min and 0.83+/-0.18 and 0.75+/-0.16 at 50 min. Prebreathing NBO and HBO significantly alleviated decompression-induced platelet activation. Activation of CD62p was 3.0+/-0.4, 13.5+/-1.3, 10.7+/-0.9, 4.5+/-0.7, and 7.6+/-0.8% for baseline, Air, NBO, HBO at 1.6 ATA, and HBO at 2.2 ATA, respectively. The data show that prebreathing oxygen, more effective with HBO than NBO, decreases air bubbles and platelet activation and, therefore, may be beneficial in reducing the development of decompression sickness.

To date, no data are available on the influence of in-water oxygen breathing on bubble formation following a provocative dive in man. The purpose of this study was to compare the effect of post-dive hyperbaric versus normobaric oxygen breathing (NOB) on venous circulating bubbles. Nineteen divers carried out open-sea field air dives at 30 msw depth for 30 min followed by a 9 min stop at 3 msw. Each diver performed three dives: one control dive, and two dives followed by 30 min of hyperbaric oxygen breathing (HOB) or NOB; both HOB and NOB started 10 min after surfacing. For HOB, divers were recompressed in-water to 6 msw at rest, whereas NOB was performed in a dry room in supine position. Decompression bubbles were examined by a precordial pulsed Doppler. Bubble count was significantly lower for post-dive NOB than for control dives. HOB dramatically suppressed circulating bubble formation with a bubble count significantly lower than for NOB or controls. In-water recompression with oxygen to 6 msw is more effective in removing gas bubbles than NOB. This treatment could be used in situations of "interrupted" or "omitted" decompression, where a diver returns to the water in order to complete decompression prior to the onset of symptoms. Further investigations are needed before to recommend this protocol as an emergency treatment for DCS.

METHODS: Eighty freshly extracted maxillary premolars were randomly divided into 4 groups (20 in each group). In all groups, the teeth were etched with 37% phosphoric acid for 20 seconds, and RMGIC (Fuji Ortho LC, GC Europe, Leuven, Belgium) was used for bracket bonding. In groups 1 and 3, the brackets were bonded directly to etched enamel surfaces; in groups 2 and 4, the etched enamel was covered with HFLCS (Pro Seal, Reliance Orthodontic Products, Itasca, Ill). Groups 1 and 2 received metal brackets, and groups 3 and 4 had ceramic brackets. The specimens were stored in distilled water at room temperature for 24 hours and subsequently tested in shear mode with a universal testing machine. After debonding, the teeth and the brackets were examined under a stereomicroscope (model SMZ-1B, Nikon, Osaka, Japan) at 20-times magnification to assess the residual adhesive on the tooth surfaces. RESULTS: Interaction between HFLCS and bracket type was not statistically significant (P = 0.15). Pretreatment with HFLCS did not cause a statistically significant change in the shear bond values of either metal or ceramic brackets (P = 0.38). Shear bond values of the ceramic brackets were higher than those of the metal brackets independent of HFLCS application (P <0.001). No significant differences were found in bond failure modes in the 4 groups. CONCLUSIONS: HFLCS application on enamel etched with 37% phosphoric acid did not affect the bond strength values and the bond failure modes of metal and ceramic brackets bonded with RMGIC. RESULTS: Interaction between HFLCS and bracket type was not statistically significant (P = 0.15).

Many studies have shown that carcinogens contained in tobacco smoke permeate across the placenta, and are found in fetus. The aim of the study was to determine the prenatal exposure to tobacco-specific carcinogenic N-nitrosamines on the basis of measurements of 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) in urine of smoking and second-hand smoke (SHS) exposed women and in the first urine of their newborns. A questionnaire documenting demographics and socio-economical data, smoking habits and exposure to SHS was completed by 121 delivering women near or at term. Maternal concentrations of cotinine and NNAL were measured in urine of the mother and the first urine of her newborn infant by liquid chromatography tandem mass spectrometry (LC/MS/MS). The mean concentration of cotinine was 439.2 ng/mg creatinine and NNAL concentration in urine of smoking women was 74.0 pg/mg creatinine, and for her newborn 78.6 pg/mg creatinine. Among mothers exposed to SHS, cotinine and NNAL mean concentration were 23.1 ng/mg creatinine, and 26.4 pg/mg creatinine. In newborns of SHS exposed mothers during pregnancy the mean concentration of NNAL was 34.1 pg/mg creatinine, respectively. Active tobacco smoking as well as passive exposure to smoking during pregnancy is an important source of tobacco specific N-nitrosamines to the fetuses as evidenced by increased concentrations of this carcinogen. Determination of NNAL in maternal urine samples can be a useful biomarker of prenatal exposure of newborn to carcinogenic nitrosamines.

They were divided according to their type of smoked material into three groups; cigarette smoker group, meassel water-pipe smoker group and cigarette and water-pipe smoker group. The aim of the study was to assess the prevalence of echo Doppler abnormalities in those patients looking for any specific pattern induced by meassel. The results have shown that the common effects of the whole smoker groups when compared to the non-smoker group were as follows: Severe reduction in FEV 1/FVC%, arterial pO2 reduction, left ventricular diastolic dysfunction, right ventricular diastolic dysfunction, impaired index of global right ventricular function, decreased pulmonary acceleration time and right ventricular enlargement. However, water-pipe smoker group if compared to cigarette smoker group showed more aggressive pulmonary obstruction, more degree of pulmonary hypertension, more right ventricular enlargement and more deterioration of right ventricular global function index. In conclusion, the hazards of heavy water-pipe meassel smoking on echo Doppler, FEV1/FVC% and arterial blood gases indices are not only similar to those of heavy cigarette smoking but also it cause more respiratory obstruction, more pulmonary hypertension and more deleterious effect on right ventricular size and global function Descriptors Humans, Male, Female, Smoking/physiology, Lung Diseases, Obstructive, Pulmonary Heart Disease, Respiratory Function Tests, Blood Gas Analysis, Echocardiography, Pulmonary Emphysema Links http://pesquisa.bvsalud.org/ghl/resource/en/emro-63456 Book Title Database GHL; http://www.globalhealthlibrary.net/ Publisher Data Source Authors Mazen,Adel Ahmed, Oraby,Sabah Saad Original/Translated Title URL Date of Electronic PMCID Editors
