Abstract

In a previous study, we developed a novel analytical method to directly and simultaneously detect taste- and odor-active compounds using graphite carbon black (GCB)-assisted laser desorption ionization mass spectrometry (LDI-MS). In this study, we aimed to evaluate food quality using a variety of soy sauces using the method to discriminate each product. Graphite carbon black-laser desorption ionization-mass spectrometry allowed the provision of hundreds of MS peaks derived from soy sauces in both positive and negative modes without any tedious sample pretreatments. Principal component analysis using the obtained MS peaks clearly distinguished three soy sauce products based on the manufacturing countries (Japan, China, and India). Moreover, this method identified distinct MS peaks for discrimination, which significantly correlated with their quantitative amounts in the products. Thus, GCB-LDI-MS analysis was established as a simple and rapid technique for food analysis, illustrating the chemical patterns of food products. [ABSTRACT FROM AUTHOR]

Abstract

Copper indium sulfide (CuInS 2 , CIS) was fabricated by co-electrodeposition (co-ED) of the Cu-In (CI) alloy on the Mo-electrode, followed by sulfurization in the presence of solid sulfur. The morphology, crystal structures and In/Cu compositions of CIS were found to depend on the preparation conditions of the CI, i.e., the solution concentration, applied potential and amount of Coulomb charge. For the mechanism of CI formation, the copper species were preferentially deposited on the Mo electrode in their initial state, and subsequently the indium species were deposited on the Cu layer by the effects of the concentration gradient at the electrode interface. Furthermore, the optimized CIS possessed a chalcopyrite structure with an In/Cu ratio of 1.0 having a band-gap at ca. 1.5 eV. The Pt-In 2 S 3 /CIS photoelectrode was applied for photocatalytic water splitting and it demonstrated high photoelectrochemical (PEC) water splitting to evolve H 2 (50 μmol h−1 cm−2) with a Faradic efficiency of 83.4% at + 0.1 V vs. RHE. The co-ED method, thus, enabled the facile fabrication of CI, and the prepared CIS clearly exhibited promising activity as a photo-absorber for PEC water splitting. Cu-In alloy was fabricated by an environmentally friendly co-electrodeposition method. The CIS formed by the sulfurization of the Cu-In alloy effectively worked for the PEC water splitting, producing H 2 under sunlight [Display omitted] • Cu-In alloy was co-electrodeposited in Cu2+/In3+ solutions by chronopotentiometry. • Concentration gradient at the interface works for Cu-In alloy formation. • CIS possessed stoichiometric chalcopyrite structures with the band-gap of 1.5 eV. • Pt-In 2 S 3 /CIS exhibited H 2 evolution from photoelectrochemical H 2 O splitting.

Abstract

OBJECTIVE To investigate the clinical outcomes of patients who underwent cardioversion compared with those who did not have cardioverson in a large dataset of patients with recent onset non-valvular atrial fibrillation. DESIGN Observational study using prospectively collected registry data (Global Anticoagulant Registry in the FIELD-AF-GARFIELD-AF). SETTING 1317 participating sites in 35 countries. PARTICIPANTS 52 057 patients aged 18 years and older with newly diagnosed atrial fibrillation (up to six weeks' duration) and at least one investigator determined stroke risk factor. MAIN OUTCOME MEASURES Comparisons were made between patients who received cardioversion and those who had no cardioversion at baseline, and between patients who received direct current cardioversion and those who had pharmacological cardioversion. Overlap propensity weighting with Cox proportional hazards models was used to evaluate the effect of cardioversion on clinical endpoints (all cause mortality, non-haemorrhagic stroke or systemic embolism, and major bleeding), adjusting for baseline risk and patient selection. RESULTS 44 201 patients were included in the analysis comparing cardioversion and no cardioversion, and of these, 6595 (14.9%) underwent cardioversion at baseline. The propensity score weighted hazard ratio for all cause mortality in the cardioversion group was 0.74 (95% confidence interval 0.63 to 0.86) from baseline to one year follow-up and 0.77 (0.64 to 0.93) from one year to two year follow-up. Of the 6595 patients who had cardioversion at baseline, 299 had a follow-up cardioversion more than 48 days after enrolment. 7175 patients were assessed in the analysis comparing type of cardioversion: 2427 (33.8%) received pharmacological cardioversion and 4748 (66.2%) had direct current cardioversion. During one year follow-up, event rates (per 100 patient years) for all cause mortality in patients who received direct current and pharmacological cardioversion were 1.36 (1.13 to 1.64) and 1.70 (1.35 to 2.14), respectively.

CONCLUSION In this large dataset of patients with recent onset non-valvular atrial fibrillation, a small proportion were treated with cardioversion. Direct current cardioversion was performed twice as often as pharmacological cardioversion, and there appeared to be no major difference in outcome events for these two cardioversion modalities. For the overall cardioversion group, after adjustments for confounders, a significantly lower risk of mortality was found in patients who received early cardioversion compared with those who did not receive early cardioversion.

Abstract

Fine particles derived from diesel engines, diesel exhaust particles (DEP), have been shown to augment gene expression of several inflammatory cytokines in human airway epithelial cells in vitro. However, it remains unclear whether or not DEP have any effect on the expression and production of eotaxin, an important chemokine involved in eosinophil recruitment into the airways. We studied the effects of DEP by using a conventional suspended DEP and by a recently established in vitro cell exposure system to diesel exhaust (Abe S, Takizawa H, Sugawara I, and Kudoh S, Am J Respir Cell Mol Biol 22: 296-303, 2000). DEP showed a dose-dependent stimulatory effect on eotaxin production by normal human peripheral airway epithelial cells as well as by bronchial epithelial cell line BET-1A as assessed by specific ELISA. mRNA levels increased by DEP were shown by RT-PCR. DEP showed an additive effect on IL-13-stimulated eotaxin expression. DEP induced NF-[kappa]B activation by EMSA as previously reported but did not induce signal transducer and activator of transcription (STAT) 6 activation according to Western blot analysis. Finally, antioxidant agents (N-acetyl cysteine and pyrrolidine dithiocarbamate), which inhibited NF-[kappa]B activation but failed to affect STAT6 activation, almost completely attenuated DEP-induced eotaxin production, whereas these agents failed to attenuate IL-13-induced eotaxin production. These findings suggested that DEP stimulated eotaxin gene expression via NF-[kappa]B-dependent, but STAT6-independent, pathways. airway epithelium; signal transduction; interleukin-13

Abstract

There is no analytical system to directly and simultaneously detect taste- and odor-active compounds. Graphite carbon black (GCB) nanoparticles, a chemical adsorbent for a variety of compounds, including gaseous molecules, which consists of nanoparticles made from multilayered sheets of sp2-conjugated atomic carbon, have the characteristics required for a surface-assisted laser desorption ionization–mass spectrometry (SALDI-MS) material. Thus, in this study, GCB-LDI-MS was developed for the simultaneous detection of taste- and odor-active compounds. The proposed GCB-LDI-MS successfully detected volatile compounds, including ethyl esters, alcohols, fatty acids, and aldehydes with up to 16 carbons (maximum carbon number of the tested compounds), which could not be detected by conventional matrix-assisted-LDI-MS. Moreover, a series of taste-active compounds (e.g., amino acids and sugars) and various volatile compounds (e.g., ethyl esters, aldehydes, alcohols, fatty acids, and lactones) as a mixture in liquid samples were also detected by the present GCB-LDI-MS. Thus, the proposed simple and rapid detection technique can digitize the analysis of flavor compounds, which provides an analytical concept for flavor scanning to evaluate the palatability of food products.
