“In this review, we describe

technical developments in breath analysis and its applications in clinical diagnosis, monitoring disease state, and assessing environmental exposure. Breath tests have been successfully employed in clinical analyses for symptoms including lung disease, oxidative stress, gastrointestinal disease, metabolic disorders, and Helicobacter pylori infection.

Although gas chromatography has been used mainly for the analysis of volatile constituents in breath samples, other techniques ON-01910 cell line (e.g., sensors and lasers) have also been used satisfactorily. The analytical results of breath analysis can be derived both qualitatively and quantitatively. However, evaluation of the data from different approaches BIX 01294 in vivo remains insufficient because of the lack of standardized procedures and poor methods of validation. Further research is therefore required to expand the applicability of breath analysis in clinical diagnosis of diseases. (C) 2012 Elsevier Ltd. All rights reserved.”
“The commercial value of marine Nannochloropsis oculata has been recognized due to its high content of eicosapentaenoic acid (> 50 % w/w). To make it as a profitable bioresource, one of the most desirable goals is to develop a quality-controlled, cost-effective, and large-scale

photobioreactor for N. oculata growth. Generally, closed culture system can offer many advantages over open system such as small space requirement, controllable process and low risk of contamination. However, oxygen accumulation is often a detrimental factor for enclosed microalgal culture that has seriously hampered the development of microalga-related industries. In this study, we proposed to use fluorochemical as oxygen carrier to overcome the challenge where four liquid fluorochemicals namely perfluorooctyl bromide, perfluorodecalin, methoxynonafluorobutane, and ethoxynonafluorobutane were investigated separately. Our results

showed that the microalgal proliferation with different fluorinated liquids was similar and comparable to the culture without a fluorochemical. When cultured in the photobioreactor with 60 % oxygen atmosphere, the N. oculata can grow up in all the fluorochemical photobioreactors, learn more but completely inhibited in the chamber without a fluorochemical. Moreover, the perfluorooctyl bromide system exhibited the most robust efficacy of oxygen removal in the culture media (perfluorooctyl bromide > perfluorodecalin > methoxynonafluorobutane > ethoxynonafluorobutane), and yielded a > 3-fold increase of biomass production after 5 days. In summary, the developed fluorochemical photobioreactors offer a feasible means for N. oculata growth in closed and large-scale setting without effect of oxygen inhibition.”
