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.

Several aerobic and heterotrophic bacteria were isolated and identified by 16S rRNA gene sequence analysis. Metagenomic DNA was also extracted to perform a denaturing gradient gel electrophoresis analysis of ribosomal genes and to construct a 16S rRNA gene metagenomic library. Denaturing gradient gel electrophoresis profiles and ribosomal libraries exhibited a limited bacterial diversity. Most of the species detected in the ribosomal library or isolated from the pipeline were assigned to Proteobacteria (Halomonas spp., Idiomarina spp., Marinobacter aquaeolei, Thalassospira sp., Silicibacter sp. and Chromohalobacter sp.) and Bacilli (Bacillus spp. and Exiguobacterium spp.). This is the first report that associates some of these bacteria with a corrosive biofilm. It is relevant that no sulfate-reducing bacteria were isolated or detected by a PCR-based method. The diversity and relative abundance of bacteria from water pipeline biofilms may contribute to an understanding of the complexity and mechanisms of metal corrosion during marine water injection in oil secondary recovery.

Methods: Transverse, observational, descriptive epidemiological study. Province of Salamanca Results: Water from water pipes, fountains, springs, wells, rivers, streams and lakes in the province of Salamanca were studied, analyzing the lead, cadmium, zinc and arsenic contents of 180 samples using Atomic Absorption Spectroscopy. Results indicated that 56% of samples analyzed showed toxic levels of cadmium, and 28% of samples gave toxic levels of lead, but showed tolerable levels of zinc and arsenic. No major differences were observed in the degree of contamination by the four elements between the four provincial district areas. Levels of contamination by the four elements were compared for water from the water supply, and samples from wells, fountains, springs and surface water, showing similar contents of the elements studied. Conclusions: Findings suggest that the water in the province of Salamanca shows 'naturally' high cadmium and lead content, probably due to the geological characteristics of the terrain.

Pub Date Free Form / Volume 24 Issue 7 Start Page 721 Other Pages 728 Notes Place of Publication ISSN/ISBN 0829-318X Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract Volatile organic compound (VOC) emissions from Sitka spruce (Picea sitchensis Bong.) growing in a range of controlled light and temperature regimes were monitored online with a proton transfer reaction-mass spectrometer (PTR-MS) operating at a temporal resolution of âˆ¼1 min. Isoprene emissions accounted for an average of more than 70% of measured VOCs and up to 3.5% of assimilated carbon. Emission rates (E) for isoprene correlated closely with photosynthetic photon flux (PPF) and temperature, showing saturation at a PPF of between 300 and 400 Î¼mol m-2 s-1 and a maximum between 35 and 38Â°C. Under standard conditions of 30Â°C and 1000 Î¼mol m -2 s-1 PPF, the mean isoprene E was 13 Î¼g g dm-1 h-1, considerably higher than previously observed in this species. Mean E for acetaldehyde, methanol and monoterpenes at 30Â°C were 0.37, 0.78 and 2.97 Î¼g gdm-1 h -1, respectively. In response to a sudden light to dark transition, isoprene E decreased exponentially by > 98% over about 3 h; however, during the first 7 min, this otherwise steady decay was temporarily but immediately depressed to âˆ¼40% of the pre-darkness rate, before rallying during the following 7 min to rejoin the general downward trajectory of the exponential decay. The sudden sharp fall in isoprene E was mirrored by a burst in acetaldehyde E. The acetaldehyde E maximum coincided with the isoprene E minimum (7 min post-illumination), and ceased when isoprene emissions resumed their exponential decay. The causes of, and linkages between, these phenomena were investigated.

The overall reported smoking prevalence among 1057 sampled students was 15.1%; cigarette smokers were 9.4% and waterpipe smokers 5.6%. While women comprised only 8.9% of cigarette smokers, they were 26.2% of waterpipe smokers. Multiple linear regression analysis showed that the most important predictors for smoking among the students were: male sex, having a smoking friend, having a smoking family member (father/mother/both), non-UAE nationality and older age. There is a need to intensify efforts to prevent young people from starting smoking and to help young smokers to stop.

No studies to date have examined whether divers with a history of DCS with or without a r/l shunt have a reduced risk of suffering recurrent DCS when diving more conservative dive profiles (CDP). METHODS: Twenty-seven divers with a history of DCS recommended previously to dive more conservatively were included in this study and retrospectively interviewed by phone to determine the incidence of DCS recurrence. RESULTS: Twenty-seven divers performed 17,851 dives before examination in our department and 9,236 after recommendations for conservative diving. Mean follow up was 5.3 years (range 0-11 years). Thirty-eight events of DCS occurred in total, 34 before and four after recommendation of CDP. Four divers had a closure of their patent foramen ovale (PFO). A highly significant reduction of DCS risk was observed after recommendation of CDP for the whole group as well as for the sub-groups with or without a r/l shunt. A significant reduction of DCS risk in respect to r/l shunt size was also observed. DISCUSSION: This study indicates that recommendations to reduce nitrogen load after DCS appear to reduce the risk of developing subsequent DCS. This finding is independent of whether the divers have a r/l shunt or of shunt size. The risk of suffering recurrent DCS after recommendation for CDP is less than or equal to an unselected cohort of divers. CONCLUSION: Recommendation for CDP seems to significantly reduce the risk of recurrent DCS.

Little research has been conducted on the temporal trends of gastroesophageal reflux disease (GERD) and Barrett's esophagus (BE), yet it is important to establish whether these conditions have also increased with time or differ by age. METHODS: The Cerner Health Facts((R)) database contains information on 35 million patients between 2001 and 2010. GERD, BE, and esophageal cancer (EC) cases were defined using International Classification of Diseases, ninth edition codes. We calculated age-adjusted rates and 95% confidence intervals for GERD, BE, and EC. RESULTS: In this population, the overall, all-age rate per 100,000 encounters for GERD was 711.9, BE was 21.6, and EC was 6.1. During 2001-2010, GERD rates increased by approximately 50% and EC rates more than doubled, but BE rates declined by approximately 40%. Trends were similar by age, and all rates were higher in Caucasians and males. CONCLUSIONS: These data indirectly support the idea that increased incidence of EC may be partially due to GERD and raise the provocative hypothesis that BE rates may be decreasing possibly as a forerunner of continued stabilization of esophageal adenocarcinoma rates and a possible subsequent decline.

Fruit flavor is shaped by combinations of sugars, acids and volatile compounds. Many efforts seek to use genomics-based strategies to identify genes controlling flavor, and then designing durable molecular markers to follow these genes in breeding populations. In this report, fruit from two cultivars, varying for presence-absence of volatile compounds, along with segregating progeny, were analyzed using GC/MS and RNAseq. Expression data were bulked in silico according to presence/absence of a given volatile compound, in this case gamma-decalactone, a compound conferring a peach flavor note to fruits. RESULTS: Computationally sorting reads in segregating progeny based on gamma-decalactone presence eliminated transcripts not directly relevant to the volatile, revealing transcripts possibly imparting quantitative contributions. One candidate encodes an omega-6 fatty acid desaturase, an enzyme known to participate in lactone production in fungi, noted here as FaFAD1. This candidate was induced by ripening, was detected in certain harvests, and correlated with gamma-decalactone presence. The FaFAD1 gene is present in every genotype where gamma-decalactone has been detected, and it was invariably missing in non-producers. A functional, PCR-based molecular marker was developed that cosegregates with the phenotype in F1 and BC1 populations, as well as in many other cultivars and wild Fragaria accessions. CONCLUSIONS: Genetic, genomic and analytical chemistry techniques were combined to identify FaFAD1, a gene likely controlling a key flavor volatile in strawberry. The same data may now be re-sorted based on presence/absence of any other volatile to identify other flavor-affecting candidates, leading to rapid generation of gene-specific markers.
