In this study, the petals collected from peony hybrid Paeonia lactiflora "Bowl of Beauty" and Calendula officinalis L. were extracted using an ethanol-water mixture assisted with microwave ultrasonic treatment. The isolation essential oil was done by hydrodistillation as well. total phenolic flavonoids content in extracts determined their antioxidant activity evaluated. highest found for P. C. ...
Maximal- and minimal-height distributions (MAHD, MIHD) of two-dimensional interfaces grown with the nonlinear equations of Kardar-Parisi-Zhang (KPZ, second order) and of Villain-Lai-Das Sarma (VLDS, fourth order) are shown to be different. Two universal curves may be MAHD or MIHD of each class depending on the sign of the relevant nonlinear term, which is confirmed by results of several lattice...
a new series of thiazolidinedione derivatives were synthesized. the structures of these compounds were established by means of ir, 1h-nmr and elemental analysis. all of the compounds were screened for antidiabetic activity on albino rats. most of the compounds showed significant antidiabetic activity when compared with the standard drug glibenclamide.
Reusable silica supported perchloric acid and potassium bisulphate have been prepared and explored as green catalysts for thiocyanation of aromatic compounds under conventional and solvent free microwave assisted conditions. The microwave assisted protocol exhibited remarkable rate accelerations and offered selective thiocyanation of aromatic and hetero aromatic compounds in good yields. Reacti...
Mixed autonomic hyperactivity disorder (MAHD) among patients with acquired brain injury can be rare. A delayed diagnosis of MAHD might exacerbate the clinical outcome and increase healthcare expenses with unnecessary testing. However, MAHD is still an underrecognized and evolving disease entity. A 25-yr-old woman was admitted the clinic due to craniopharyngioma. After an extensive tumor resecti...
