With bubble contrast, 11 (37%) of the patients had right-to-left shunting through a patent foramen ovale during spontaneous breathing. 61% of a subset of 18 patients with serious signs and symptoms had shunting. This number was significantly higher than the 5% prevalence seen with the same diagnostic technique in 176 healthy volunteers. The presence of patent foramen ovale seems to be a risk factor for the development of decompression sickness in divers.

It is now an increasingly popular form of smoking among youth in North America. Health professionals/educators knowledge about the WP may well be inadequate. This study, using qualitative methods, sought to explore the knowledge and attitude of leaders in the community toward the WP. Family physicians, pharmacists, tobacco counsellors, social workers and educators were invited to participate in a one-one interview using open-ended questions. A total of 27 interviews were conducted. Individuals from Eastern Mediterranean backgrounds raised doubt about the overemphasised cultural significance of the WP and perceived this as a marketing strategy by industry. Most felt that WP smokers believed the WP to be less harmful than cigarettes and that the use of flavoured tobacco was motivating people to smoke. Participants believed that education should be directed at the general public and healthcare professionals, suggesting school programs and the use of social media to inform young smokers. Most thought that the current practices regarding packaging and second hand smoke exposure are confusing. They identified the lack of knowledge, poor enforcement procedures, "so called cultural aspects" and the economic impact of banning the WP on small businesses as barriers to change. Despite the awareness of an increase in WP use, our participants recognized that little has been done to curb this problem. Our findings emphasize the need for further education and better legislation to regulate WP use and availability.

He was able to differentiate it clearly from vascular blood and lymph systems by the use of a variety of methods, which were available to him in the mid-20th century. He gave detailed characterization of the system and created comprehensive diagrams and photographs in his publications. He demonstrated that this system is composed of nodes and vessels, and it was responsible for tissue regeneration. However, he did not disclose in detail his methods. Consequently, his results are relatively obscure from the vantage point of contemporary scientists. The stains that Kim used had been perfected and had been in use for more than 100 years. Therefore, the names of the stains were directed to the explicit protocols for the usage with the particular cells or molecules. Traditionally, it was not normally necessary to describe the method used unless it is significantly deviated from the original method. In this present work, we have been able to disclose staining methods used by Kim. Descriptors Links Book Title Database Publisher Data Source Authors Vodyanoy,V., Pustovyy,O., Globa,L., Sorokulova,I.

The aim of this study was to assess the diet and subsistence strategies of humans that lived during the later Lapita period in Near Oceania. To aid in the interpretation of the human diet we analyzed the stable isotope ratios of faunal material from the site (n = 27). We also aim to assess methods of animal husbandry at the site over time from an analysis of the stable isotope ratios (delta(13)C and delta(15)N) of pig bones (n = 22) from different temporal periods (Lapita, post-Lapita, and late prehistoric). The protein diet of the humans consisted of marine organisms from the inshore environment and some deep-water species, most likely marine turtle, in addition to higher trophic level terrestrial foods, likely pig and native animals (e.g., fruit bat, Cuscus and bandicoot). Although the sample sizes were small, females (n = 4) displayed more variable delta(13)C and delta(15)N values compared with males (n = 4), which may be associated with the movement of adult females to the island. The stable isotope analysis of the pig bones indicated that there were few differences between the diets of the pigs from the Lapita and post-Lapita layers, suggesting that the method of pig husbandry was similar between these two periods and was likely relatively free-range.

The LC method was coupled with a triple quadrupole mass spectrometer, using an ESI source in positive mode and using the [M+NH(4)](+) adduct as precursor ion for tandem mass spectrometry experiments. The method developed was applied to the determination of these compounds in canned soft drinks and canned food. OASIS HLB solid phase extraction (SPE) cartridges were used for the analysis of soft drinks, while solid canned food was extracted with ethyl acetate. Method limits of quantitation ranged from 0.13 mugL(-1) to 1.6 mugL(-1) in soft drinks and 1.0 mugkg(-1) to 4.0 mugkg(-1) in food samples. BADGE.2H(2)O was detected in all the analyzed samples, while other BADGEs such as BADGE.H(2)O, BADGE.HCl.H(2)O, BADGE.HCl and BADGE.2HCl were also detected in canned foods.

A 65-microm polydimethylsiloxane-divinylbenzene (PDMS/DVB) fiber was used, and parameters affecting the extraction procedures such as extraction temperature and time, desorption temperature and time, splitless time, effect of an organic modifier or ionic adjustment were studied. The linearity and precision of the proposed method were satisfactory. The use of GC-MS determination in the full scan mode, in the selected ion monitoring (SIM) mode, and in the GC-MS-MS mode provided the unequivocal identification and quantification of the target analytes. Moreover, the proposed SPME-GC-MS-MS method, extracting only 18 ml of sample, reached the very restrictive limits fixed by the 2006/0129 EC proposal for a new water directive to be achieved by 2015. The matrix effects were evaluated through the analysis of tap, well, superficial, and seawater. A discussion on different behaviors, a result of the matrix effects, was included. Analytical recoveries were satisfactory in all cases. The novelty of this work consisted in the wide range of analyzed PAHs, the very low detection limits that were reached, the coupling of SPME-GC-MS-MS, and the study of the matrix effect on water samples. With this developed procedure, detection limits between 0.07 and 0.76 ng l(-1) and quantification limits between 0.10 and 0.98 ng l(-1) were obtained with MS-MS detection. Moreover, the analytical recoveries for different aqueous matrices were near 100% in all cases.

The procedure is based on pressurized hot water extraction (PHWE) followed by solid-phase microextraction (SPME) and determination by gas chromatography-mass spectrometry. For PHWE, parameters such as organic modifier, percentage of organic modifier, temperature, and static extraction time were studied. For SPME, extraction temperature and time, desorption temperature and time, splitless time, ionic strength adjustments, and effect of an organic modifier were studied. When these parameters were selected, the figures of merit were calculated. The detection and quantification limits were between 0.4-15 microg kg(-1) and 1.2-51 microg kg(-1), respectively. The linearity of the method was assessed spiking sediment samples at seven levels of concentration ranged between 2.5 microg kg(-1) and 500 microg kg(-1) for most of the studied PAHs. The method was validated by two concentration levels reference marine sediment materials (SRM 1944 and SRM 1941b). The obtained results are in very good agreement with the certificate materials. The developed method seems to be suitable for the analysis of PAHs at ultratrace levels in environmental matrices as sediment samples.

These compounds mean serious risks for public and occupational health and for biological and physical environments. A total of 1200 samples were analysed during a year, and in most of the samples toluene was the most abundant VOC followed by benzene or m+p-xylene. The average concentrations were 1.62, 2.15, 0.60, 0.94 and 0.47 microg m(-3) for benzene, toluene, ethylbenzene, m+p-xylenes and o-xylene respectively, although they reached values as high as 50.53, 28.57, 21.33, 46.13 and 22.74 microg m(-3) for the compounds in the same order. An exhaustive study was carried out to establish how both emission sources and the climatic conditions affected the BTEX levels measured in the outskirts of a small city. Wind directions and speeds, daily and seasonal BTEX profiles, ratios among the concentrations measured in the sampling site, in the city centre and in the fuels commonly used by the cars in the city were studied. The pollution roses revealed the presence of diffuse BTEX sources affecting the sampling point, although all the compounds reached their highest levels when the wind blew from an industrial area in the SW of the city. The daily BTEX profiles were well-correlated with the traffic pattern in the accesses to the city and the seasonal profile showed that the highest concentrations were reported in summertime. The ratios T/B, m+p-X/B and o-X/B were 1.32, 0.58 and 0.29 respectively; these values were lower than the ones reported in previous studies carried out in the centre of the same city. This could be caused by the major distance from the sampling point to the city centre and by the changes in the fuels and in the kind of vehicles used in the city. The correlation coefficients among the TEX fraction were always higher than 0.72 but benzene only showed a good correlation with these compounds in winter. The correlations between BTEX concentrations and their contributions to the photochemistry in the sampling area were used in order to evaluate the distance from the road traffic source and to estimate the presence of fresh or old air masses in the sampling point. This study provides data which can be useful to establish the BTEX levels in suburban areas from the coastal Atlantic region and improves the knowledge of the BTEX presence in this kind of area.

The as-synthesized MNPs have been successfully used as sorbent for the extraction of polycyclic aromatic hydrocarbons (PAHs) from water samples, the analytes being finally determined by gas chromatography/mass spectrometry. The influence of several experimental variables (including the ionic strength, amount of MNPs, sample volume, agitation time and desorption solvent) has been considered in depth in the optimization process. The developed method, which has been analytically characterized under its optimal operation conditions, allows the detection of the analytes in the samples with method detection limits in the range from 0.04mugL(-1) (fluoranthene) to 1.11mugL(-1) (indeno(1,2,3-cd)pyrene). The repeatability of the method, expressed as relative standard deviation (RSD, n=7), varies between 4.0% (benzo[b]fluoranthene) and 8.9% (acenaphthene), while the enrichment factors are in the range from 49 (naphthalene) to 158 (fluoranthene). The proposed procedure has been applied for the determination of thirteen PAHs in water samples (tap, river, well and reservoir ones) with recoveries in the range from 75 to 102%.

Apart from method parameter optimization the influence of humic acids as matrix components on the extraction efficiency of MEPS procedure was also evaluated. The list of target compounds includes polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), phthalate esters (PEs), nonylphenols (NPs), bisphenol A (BPA) and selected steroid hormones. The performance of the new at-line microextraction-LVI-GC-MS protocol was compared to standard solid-phase extraction (SPE) and LVI-GC-MS analysis. LODs for 100 mL samples (SPE) ranged from 0.2 to 736 ng L(-1) were obtained. LODs for 800 microL of sample (MEPS) were between 0.2 and 266 ng L(-1). In the case of MEPS methodology even a sample volume of only 800 microL allowed to detect the target compounds. These results demonstrate the high sensitivity of both procedures which permitted to obtain good recoveries (>75%) for all cases. The precision of the methods, calculated as relative standard deviation (RSD) was below 21% for all compounds and both methodologies. Finally, the developed methods were applied to the determination of target analytes in various samples, including snow and wastewater.
