“Introduction: To systematically review the relationship between low pH in intervertebral discs and low back pain.\n\nMaterial and methods: Electronic database (Pub Med, 151 Web of Science, Cochrane Library, CINAHL, AMED, and China National Knowledge Infrastructure) searches and hand searching of conference proceedings were conducted. Two authors independently evaluated the methodological quality and abstracted relevant data according to standard criteria. Then the experimental methods and samples employed in the finally retrieved articles were assessed.\n\nResults: We first retrieved 136 articles regarding pain and pH, and only 16 of them were mainly about low back pain and pH. Finally, 7 articles met our expectation to focus on the pathogenesis of low back pain caused by pH. In these 7 studies the authors held three opinions to explain the pathogenesis of low back pain in relation to low pH. First, low

pH caused by lactate stimulates the muscle and increases the muscle tension, which causes low back pain. Second, low pH stimulates the nerve roots and produces the feeling of pain. Third, low pH changes the learn more matrix metabolism, leading to neuronal death and low back pain.\n\nConclusions: In this systematic review we propose a new hypothesis that low back pain may be caused by low pH based on the previous literature. Further experimental this website studies are necessary to verify our hypothesis. This hypothesis will promote our understanding of the pathogenesis of low back pain and the development of novel diagnostic and therapeutic approaches for low back pain.”
“The effects of support materials-lanthanum oxide, cerium

oxide, zirconium oxide, titanium oxide, g-alumina, and ZSM-5-on the transesterification activity of CaO-La2O3 and CaO-CeO2 catalysts were investigated. The metal composition and surface acidity (or basicity) of the supported catalysts played a significant role in determining the activity of the catalyst. Results showed that both catalytic activity and basicity of the supported catalysts decreased in the following order: CaO-La2O3/La2O3 >= CaO-La2O3/CeO2 > CaO-La2O3/ZrO2 > CaO-La2O3/g-Al2O3 > CaO-La2O3/ZSM-5 > CaO-La2O3/TiO2. In addition, leaching of Ca species from the catalyst was more pronounced with basic supports. However, Ca leaching could be minimized by coupling with La2O3 or CeO2 on an appropriate support. This was verified in a flow reactor study of the CaO-CeO2/La2O3 catalyst, where, over 200 h of continuous operation, the transesterification yield held constant at 88-90% while the initial Ca concentration in the product decreased from 194 ppm to below 5.0 ppm after 144 h.
