The cloud point of copolymers of 2-ethyl-2-oxazoline and 2-n-propyl-2-oxazoline could be tuned from 25 degrees C to 100 degrees C by varying molecular weight and composition; the reversibility and concentration dependence of the cloud points were evaluated to assess the potential of these copoly(2-oxazoline)s as alternatives to poly(N-isopropylacrylamide).

introduction: β-carbolines are shown to have significant anti-inflammatory effect via the inhibition of some inflammatory mediators including tnf-α and pge2. in previous studies purkinje cell deterioration have been proposed the dominant pathogenesis of harmaline toxicity. win55, 212-2 is a non-selective cannabinoid cb1 and cb2 receptor agonist. combination of win55, 212-2 and am 251(cb1-select...

An inexpensive synthesis of 6-ethynylbipyridine has been accomplished using Sonogashira coupling of 2-bromo-6-iodopyridine with 2-methyl-3-butyn-2-ol. Subsequent Stille coupling with 2-(trimethylstannanyl) pyridine and hydrolysis provided the target compound in an overall high yield.

introduction: the 2×2 model is the newest model of perfectionism that has been raised several hypotheses about the compatibility’s level of different types of perfectionism. the main aim of this study is to test these hypotheses. methods : a hundred and ninety eight ma students were selected through a cluster random sampling and were divided into four groups based on perfectionism’s types with ...
