nanocomposite samples based on elastomer blends of butyl rubber (iir) and ethylene propylene diene monomer (epdm) were prepared using a laboratory scale two-roll mill in order to study the effect of cloisite 15a organoclay content (i.e., 1, 3, 5 and 7 wt%) on the mechanical and morphological properties  of  iir/epdm/cloisite  15a  nanocomposites  compared  to  the  unflled epdm/iir blends. rheo...

       Volatile constituents of the seed kernel and leaf of cultivated Moringa peregrina (Forssk.) Fiori, Agricolt collected after hydrolysis were analyzed by GC and GC/MS. Five glucosinolate degradation products which constituted almost the whole isolated oil of the seed kernel were identified to be: isobutyl isothiocyanate (94.0%), isopropyl isothiocyanate (4.9%), sec-butyl isothiocy...

Stearoyl-coenzyme A desaturase 1 (SCD1) catalyzes the conversion of stearate (18:0) to oleate (18:1n-9) and of palmitate (16:0) to palmitoleate (16:1), which are key steps in triglyceride synthesis in the fatty acid metabolic network. This study investigated the role of SCD1 in fatty acid metabolism in HepG2 cells using SCD1 inhibitors and stable isotope tracers. HepG2 cells were cultured with ...

Amylose?sodium stearate (SS) complexes (2, 5 and 8%) in heat-moisture treated potato starch (HPS) were evaluated for their physicochemical properties. Based on the DSC thermograms, amylose - SS successfully formed with high thermal stability, indicated by a melt temperature (Tpeak) of ? 112 °C type I ?125 II complexes. Addition 2% resulted single endothermal peak complexes, while 8% led to form...

Abstract Changing relative humidity levels challenge the manufacturing of chewable xylitol-sorbitol based tablets. The aim study is to investigate how formulation tablets affects properties powder blends and in an environment different levels. In all, 30 batches containing ratios sorbitol, xylitol magnesium stearate were prepared at three Powder made into using instrumented eccentric tableting ...
