Inversion algorithms such as singular value decomposition (SVD), Non-negative least square (NNLS), Solid iteration rebuild technique (SIRT) have been widely used in analyzing NMR data to obtain a T1 or T2 spectrum. However, due to the ill-conditioned nature of such inversion, it is difficult to determine the reliability of the inversion result. The concrete model is realized in MATLAB according the thought of the above three algorithms in this article. We converged to the true distribution by matching up the inversion spectrum from a series of true decay data collected from the NMR analyst instrument and a noisy simulated model, then evaluated the effects of noise in the original NMR data.","PeriodicalId":6396,"journal":{"name":"2010 4th International Conference on Bioinformatics and Biomedical Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78333824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cationic polyacrylamide (CPAM) made by ourselves is with high molecular weight and high charge density, and its stability and dissolvability are both excellent.

The adsorbent was assessed through chromatographer and batch system assays in terms of adsorption capacity, selectivity for both polycloneantibodies in normal human plasma and pathogenic antibodies in patients' sera. For human immunoglobulin G (IgG), capacities of >30 mg/mL at 10% breakthrough (pH 7.4, linear flow rate of 212 cm/hr) were regularly achieved without adding salt. Removal percentage of immunoglobulins (Igs) in plasma samples was 34.2±±4.0%, while that of albumin was less than 3% at the ratio of 5 sample volumes per adsorbent volume. Rheumatoid factors in serum samples from 8 rheumatoid arthritis (RA) patients were eliminated at different degrees after treatment by the adsorbent. The results indicated that BA-based agrose was effective in selectively adsorbing human antibodies from plasma, could thus have a potential ability to eliminate pathogenic autoantibodies in apheresis.","PeriodicalId":6396,"journal":{"name":"2010 4th International Conference on Bioinformatics and Biomedical Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77931292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their structural properties were characterized by FT-IR and their moisture absorption-retention ability were explored and compared with those of hyaluronic acid (HA), respectively. Carboxymethyl and quaternary ammonium salt groups are anionic and cationic groups, which are both hydrophilic. Thereby, hydrogen bonds readily develop interactions between the derivatives' chains and water molecules. As a result, CMI and QI tended to hold more water molecules. Therefore, CMI and QI showed much stronger moisture absorption-retention ability than those of inulin. CMI should be further explored in cosmetic and clinical fields as HA substitute due to its more excellent moisture retention-absorption ability.","PeriodicalId":6396,"journal":{"name":"2010 4th International Conference on Bioinformatics and Biomedical Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78060117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The soil type illustrated a significant influence on the TPH cleanup effect, while the TPH removal in four types of soils ranged from 46.7% to 83.1%.
