The aim was to identify the atmospheric emission sources of soluble compounds in rainwater samples, and the sample collection was performed with an automatic sampler. Anions and cations were separated and quantified by ion chromatography, whereas trace metals and metalloids were determined by inductively coupled plasma mass spectrometry. SPCA results showed eight interfering PCs and ten significant PCs. The interfering cases originated from different atmospheric sources, such as resuspended crustal particles, marine aerosols, urban traffic and a fertilizer factory. The significant PCs explained 84.6% of the total variance; 28.1% accounted for the main contribution, which was resuspended industrial soil from a fertilizer factory containing NO (2) (-) , NH (4) (+) , NO (3) (-) , SO (4) (2-) , F(-), Al, K(+), Mn, Sb and Ca(2+) as indicators of the fertilizer factory. Another important source (15.0%) was found for Na(+), Mg(2+), K(+), Cl(-) and SO (4) (2-) , which represents the marine influence from south and southwest directions. Emissions of Ba(2+), Pb, Sr(2+), Sb and Mo, which represent a traffic source deposited in soils, were identified as another abundant contribution (12.1%) to the rainwater composition. Other important contributions to the rainwater samples that were identified through SPCA included the following: different urban emissions (Cu, As, Cd, Zn, Mo and Co, 18.1%), emissions from vegetation (HCOO(-), 7.7%) and emissions from industrial combustion processes (Ni, V 15.6%).

The extract was passed through a Florisil mini-column for cleanup with 10 mL of acetone-n-hexane (1:9) mixture. Although the sensitivity of GC-AED was inferior to that of GC-ECD, GC-AED has a superior element-selectivity. Therefore pesticide residues in foods could be analyzed more exactly by using GC-AED.

The remnant values by subtracting the standard values and the GA-PLS validation values were regarded as the output of ANN. The ANN model was made to predict the nonlinear part of the protein content. The final result of the model was the addition of the two model's validation values, and the root mean squared error of prediction (RMSEP) was used to estimate the mixed model. A full region PLS model (Fr-PLS) was also made, and the RMSEP of the Fr-PLS, GA-PLS and GA-PLS+PC-ANN model was 0.511, 0.440 and 0.235, respectively. The results show that the prediction precision of the protein model for milk powder was largely improved when adding the nonlinear port in the NIR model, and this method can also be used for other complex material to improve the prediction precision.", "publicationTitle": "Guang Pu Xue Yu Guang Pu Fen Xi = Guang Pu", "publisher": "", "place": "", "date": "Jul 2009", "volume": "29", "issue": "7", "section": "", "partNumber": "", "partTitle": "", "pages": "1818-1821", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Guang Pu Xue Yu Guang Pu Fen Xi", "DOI": "", "citationKey": "", "url": "http://www.ncbi.nlm.nih.gov/pubmed/19798948", "accessDate": "2010-11-06T16:55:07Z", "PMID": "", "PMCID": "", "ISSN": "1000-0593", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "NCBI PubMed", "callNumber": "", "rights": "", "extra": "PMID: 19798948", "tags": [ { "tag": "Algorithms", "type": 1 }, { "tag": "Least-Squares Analysis", "type": 1 }, { "tag": "Milk Proteins", "type": 1 }, { "tag": "Milk Substitutes", "type": 1 }, { "tag": "Models, Statistical", "type": 1 }, { "tag": "Neural Networks (Computer)", "type": 1 }, { "tag": "Powders", "type": 1 }, { "tag": "Principal Component Analysis", "type": 1 } ], "collections": [], "relations": {}, "dateAdded": "2010-11-06T16:55:07Z", "dateModified": "2011-03-07T05:26:23Z" } }, { "key": "VR727FGG", "version": 1, "library": { "type": "group", "id": 21547, "name": "Statistics", "links": { "alternate": { "href": "https://www.zotero.org/groups/statistics", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/21547/items/VR727FGG", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/statistics/items/VR727FGG", "type": "text/html" } }, "meta": { "createdByUser": { "id": 119088, "username": "Rayaloha", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/rayaloha", "type": "text/html" } } }, "creatorSummary": "Sharaf et al.", "parsedDate": "1986", "numChildren": 1 }, "data": { "key": "VR727FGG", "version": 1, "itemType": "book", "title": "Chemometrics", "creators": [ { "creatorType": "author", "firstName": "Muhammad A.", "lastName": "Sharaf" }, { "creatorType": "author", "firstName": "Deborah L.", "lastName": "Illman" }, { "creatorType": "author", "firstName": "Bruce R.", "lastName": "Kowalski" } ], "abstractNote": "", "series": "", "seriesNumber": "", "volume": "", "numberOfVolumes": "", "edition": "", "date": "1986", "publisher": "Wiley-IEEE", "place": "", "originalDate": "", "originalPublisher": "", "originalPlace": "", "format": "", "numPages": "350", "ISBN": "9780471831068", "DOI": "", "citationKey": "", "url": "", "accessDate": "", "ISSN": "", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "Google Books", "callNumber": "", "rights": "", "extra": "", "tags": [], "collections": [], "relations": {}, "dateAdded": "2011-02-15T09:29:00Z", "dateModified": "2011-02-15T09:29:00Z" } }, { "key": "A5B2AZHJ", "version": 1, "library": { "type": "group", "id": 21547, "name": "Statistics", "links": { "alternate": { "href": "https://www.zotero.org/groups/statistics", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/21547/items/A5B2AZHJ", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/statistics/items/A5B2AZHJ", "type": "text/html" } }, "meta": { "createdByUser": { "id": 119088, "username": "Rayaloha", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/rayaloha", "type": "text/html" } } }, "creatorSummary": "Balasubramanian and Qian", "parsedDate": "2004-10", "numChildren": 0 }, "data": { "key": "A5B2AZHJ", "version": 1, "itemType": "journalArticle", "title": "Characterization and source identification of airborne trace metals in Singapore", "creators": [ { "creatorType": "author", "firstName": "R", "lastName": "Balasubramanian" }, { "creatorType": "author", "firstName": "W-B", "lastName": "Qian" } ], "abstractNote": "Airborne particulate trace metals have important health implications.

In this study, fine atmospheric particles (PM(2.5)) were collected in Singapore over a period of 83 consecutive days during 2000, and analysed to determine the concentration of trace elements using ICP-MS. Altogether, eighteen airborne trace metals were quantified: Al, Ag, Ba, Cd, Cr, Co, Cu, Fe, Ga, Li, Mn, Ni, Pb, Sr, Zn, V, Si, and Ti. While Li was the least abundant trace metal with a mean concentration of 0.2 ng m(-3), Zn showed the maximum mean concentration of 279.1 ng m(-3). Calculation of enrichment factors indicated that the elements Pb, Zn, Cd, V, Ni, Cr, and Cu were enriched by factors of 30 to 5000 relative to their natural abundance in crustal soil. The extent of metal pollution in the study area was assessed by comparing the measured concentrations to those reported in the literature for a selected number of urban sites in other parts of the world. Factor analysis was used to identify the major sources affecting particulate air pollution in Singapore. The sources that contribute to the loading of trace metal-bearing aerosols in the Singapore urban atmosphere include fuel oil-fired power plants, metal processing industry, land reclamation and construction activities, municipal solid waste incinerators, and traffic emissions.", "publicationTitle": "Journal of Environmental Monitoring: JEM", "publisher": "", "place": "", "date": "Oct 2004", "volume": "6", "issue": "10", "section": "", "partNumber": "", "partTitle": "", "pages": "813-818", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "J Environ Monit", "DOI": "10.1039/b407523d", "citationKey": "", "url": "http://www.ncbi.nlm.nih.gov/pubmed/15480495", "accessDate": "2011-02-04T07:02:43Z", "PMID": "", "PMCID": "", "ISSN": "1464-0325", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "NCBI PubMed", "callNumber": "", "rights": "", "extra": "PMID: 15480495", "tags": [ { "tag": "Acids", "type": 1 }, { "tag": "Air Pollutants", "type": 1 }, { "tag": "Cities", "type": 1 }, { "tag": "Environmental Monitoring", "type": 1 }, { "tag": "Factor Analysis, Statistical", "type": 1 }, { "tag": "Mass Spectrometry", "type": 1 }, { "tag": "Metals", "type": 1 }, { "tag": "Particle Size", "type": 1 }, { "tag": "Singapore", "type": 1 }, { "tag": "Spectrophotometry, Atomic", "type": 1 }, { "tag": "Time Factors", "type": 1 } ], "collections": [], "relations": {}, "dateAdded": "2011-02-04T07:02:43Z", "dateModified": "2011-02-04T07:02:43Z" } }, { "key": "QJQV3ZFH", "version": 1, "library": { "type": "group", "id": 21547, "name": "Statistics", "links": { "alternate": { "href": "https://www.zotero.org/groups/statistics", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/21547/items/QJQV3ZFH", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/statistics/items/QJQV3ZFH", "type": "text/html" } }, "meta": { "createdByUser": { "id": 119088, "username": "Rayaloha", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/rayaloha", "type": "text/html" } } }, "creatorSummary": "Ariyama et al.", "parsedDate": "2004-05", "numChildren": 0 }, "data": { "key": "QJQV3ZFH", "version": 1, "itemType": "journalArticle", "title": "Chemometric techniques on inorganic elements composition for the determination of the geographic origin of Welsh onions", "creators": [ { "creatorType": "author", "firstName": "Kaoru", "lastName": "Ariyama" }, { "creatorType": "author", "firstName": "Hiroshi", "lastName": "Horita" }, { "creatorType": "author", "firstName": "Akemi", "lastName": "Yasui" } ], "abstractNote": "Techniques to determine the producing country of Welsh onions (Allium fistulosum L.) were developed by using 216 samples from Japan and from Anchu Shandgon, Shanghai and Amoy Fjian in China.

To do so, pregnant mice were randomly divided into two groups. The one group was injected with dexamethasone. On E17.5th day, the incident rates of cleft palate from embryos in two groups were calculated. The (1)H-NMR spectra from the metabolites in plasma in two groups was collected at same time. Then the data were analyzed using metabonomics methods (PCA and SIMCA). The results showed that the data from the two groups displayed distinctive characters, and the incidence of cleft palate were significantly different (P < .005). To conclude, this study demonstrates that the metabonomics approach is a powerful and effective method in detecting the abnormal metabolites from mother in the earlier period of embryos, and supports the idea that a change from dexamethasone induced in maternal metabolites plays an important role in the incidence of cleft palate.", "publicationTitle": "Journal of Biomedicine & Biotechnology", "publisher": "", "place": "", "date": "2011", "volume": "2011", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "J.

As the natural occurrence is very rare, a source of supply for C. Bovis is far behind the actual need and great efforts have been taken for some substitutes of natural C. Bovis. Unfortunately, very little information is available on the quality and/or clinical efficacy of medication based on C. Bovis. To ensure sustainable use of traditional therapeutic agents derived from C. Bovis, we felt that several issues needed to be addressed: 1) the source of the C. Bovis materials and quality control; 2) the role of taurine in the efficacy of C. Bovis. METHODS: Nine samples of natural C. Bovis and its substitutes were collected. ICP-MS was used for elemental analysis and the characterization was performed by principal component analysis (PCA) and soft independent modeling of class analogy (SIMCA) as multivariate approaches. The efficacy of C. Bovis was evaluated for morphology, viability and beating pattern on cultured cardiac myocytes and/or fibroblasts. RESULTS: PCA and multi-elemental focus was effective in discriminating C. Bovis samples derived from different habitats. A satisfactory classification using SIMCA was obtained among Australia C. Bovis, other habitats and the substitutes. Australian samples had better batch uniformity than other habitats and were composed of fewer elements. We have used Australian C. Bovis for assessment on its bioactive compounds. Rat cardiac cells incubated with C. Bovis extract (0.01-0.1 mg/ml) maintained normal morphology, viability and beating pattern. Cardiac myocytes and fibroblasts treated for 48 h with CA (0.5 mM) or DCA (0.1 mM) caused cell injury, as reflected by changes in appearance and a reduction of viability detected by the MTS assay. In cardiomyocytes, 0.5 h exposure of CA (0.5 mM) markedly decreased the velocity ratio of beating, whereas the simultaneous addition of 1 mM taurine largely prevented the decrease. CONCLUSIONS: The multi-elemental focus provided some references for the quality control and the efficacy of C. Bovis. Taurine partly attenuated the harmful actions of bile acids. It is plausible that the relationship between taurine and the bile acids contributes to therapeutic effect of C. Bovis.", "publicationTitle": "Journal of Biomedical Science", "publisher": "", "place": "", "date": "2010", "volume": "17 Suppl 1", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "S44", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "J.
