The results for the mechanical Z-DEVD-FMK in vivo properties showed that the processing aids increased the impact strength significantly (up to three times that of neat PP) but reduced the flexural modulus of PP nanocomposites. PPG, which is polar promoted wetting MMT surface, thus increasing its inter-layer distance, mainly for PP/C-20A nanocomposites. However, it reduced the interfacial adhesion between the clay and the matrix. Nanocomposites impact strength was improved, especially when the C-15A organoclay was used, while were achieved better results with the C-20A organoclay when EMCA was used. The larger the amount of processing aid added, the higher the impact strength, but the lower the flexural modulus of the nanocomposites.
PPG caused debonding of the clay particles and increased the number of microvoids, generating more mechanisms to aid in the energy dissipation of the systems. EMCA promoted debonding of clay particles with the formation of fibrils, indicating
stronger interactions between the clay and matrix. A slight nucleation effect for PP crystallization was observed, mainly when EMCA was used. (C) 2010 Wiley Periodicals, Inc. J Appl Polym Sci 119: 15671575, 2011″
“Study Design. Systematic review.
Objective. To assess the efficacy of Chinese herbal medicines in treating chronic neck pain with radicular signs or symptoms.
Summary of Background Data. Chronic neck pain with radicular signs or symptoms is a common condition. Many patients use complementary and alternative medicine, including traditional Chinese medicine, to address their symptoms.
Methods. We electronically searched MI-503 inhibitor CENTRAL, MEDLINE, EMBASE, CINAHL, and AMED (up to 2009), the Chinese Biomedical Database and related herbal medicine data-bases in Japan and South Korea (up to 2007). We also contacted content experts and hand searched
a number of journals published in China.
We included randomized controlled trials with adults with a clinical diagnosis of cervical degenerative disc disease, cervical radiculopathy, or myelopathy supported by appropriate radiologic check details findings. The interventions were Chinese herbal medicines. The primary outcome was pain relief, measured with a visual analogue scale, numerical scale, or other validated tool.
Results. All 4 included studies were in Chinese; 2 of which were unpublished. Effect sizes were not clinically relevant and there was low quality evidence for all outcomes due to study limitations and sparse data (single studies). Two trials (680 participants) found that Compound Qishe Tablets relieved pain better in the short-term than either placebo or Jingfukang; one trial (60 participants) found than an oral herbal formula of Huangqi relieved pain better than Mobicox or Methycobal, and another trial (360 participants) showed that a topical herbal medicine, Compound Extractum Nucis Vomicae, relieved pain better than Diclofenac Diethylamine Emulgel.
Conclusion.
