Studies on one‐dimensional polyanilines prepared with n‐dodecylbenzenesulfonic and camphorsulfonic acids

Anilinium salts complexed with n‐dodecylbenzenesulfonic acid (DBSA) and camphorsulfonic acid (CSA) were found to self‐assemble into cylindrical micelles with bigger diameters than those complexed with only DBSA or CSA. These cylindrical micelles were polymerized into one‐dimensional copolyaniline nanotubes (PANIDBSACSA) via emulsion polymerization, demonstrating various morphologies depending on the ratio of DBSA to CSA. The UV?visible?NIR spectra of neat PANICSA and PANIDBSACSAs illustrate significant free carrier tails in the NIR region and conductivity 10–20 times higher than that of neat PANIDBSA whose UV?visible?NIR spectrum does not illustrate significant carrier tails. When the number of moles of DBSA is equivalent to or exceeds that of CSA in the polymerization mixture, SEM and TEM micrographs of the PANIDBSACSAs reveal that they have larger diameters than that of neat PANIDBSA. Besides, some of the surfaces of the big nanotubes were implanted and mounted with lots of small nanofibers of neat PANICSA polymerized from some of the CSA‐complexed aniliniums which were excluded from the cylindrical micelles before polymerization. TGA thermograms of PANIDBSACSAs show an intimate relationship between thermal deprotonation and the DBSA to CSA ratio. X‐ray diffraction patterns demonstrate a layered structure arrangement of polyaniline molecules of all one‐dimensional nanofibers. © 2015 Society of Chemical Industry     

Heat Killed Lactobacillus reuteri GMNL-263 Reduces Fibrosis Effects on the Liver and Heart in High Fat Diet-Hamsters via TGF-β Suppression

Obesity is one of the major risk factors for nonalcoholic fatty liver disease (NAFLD), and NAFLD is highly associated with an increased risk of cardiovascular disease (CVD). Scholars have suggested that certain probiotics may significantly impact cardiovascular health, particularly certain Lactobacillus species, such as Lactobacillus reuteri GMNL-263 (Lr263) probiotics, which have been shown to reduce obesity and arteriosclerosis in vivo. In the present study, we examined the potential of heat-killed bacteria to attenuate high fat diet (HFD)-induced hepatic and cardiac damages and the possible underlying mechanism of the positive effects of heat-killed Lr263 oral supplements. Heat-killed Lr263 treatments (625 and 3125 mg/kg-hamster/day) were provided as a daily supplement by oral gavage to HFD-fed hamsters for eight weeks. The results show that heat-killed Lr263 treatments reduce fatty liver syndrome. Moreover, heat-killed Lactobacillus reuteri GMNL-263 supplementation in HFD hamsters also reduced fibrosis in the liver and heart by reducing transforming growth factor β (TGF-β) expression levels. In conclusion, heat-killed Lr263 can reduce lipid metabolic stress in HFD hamsters and decrease the risk of fatty liver and cardiovascular disease.
