gundelia tournefortii l. is a well known plant in mountains of iran and is found all over the country. it traditionally has some medicinal applications. in this research, gundelia tournefortii l. seed was studied as a source of edible oil. oil was extracted with immersion method using diethyl ether as a solvent. acidity, saponification, ester, iodine, peroxide and refractive indices, average mo...

densely functionalized 3-(4-chlorophenyl)-5-(3-hydroxy-4-etoxyphenyl)-4,5-dihydro-1h-pyrazole-1-carboxamide was  synthesized in an expedient manner through specification and transamidation  respectively, of ester-functionalized pyrazoles. this synthetic protocol allowed for three diversifying steps in which appendages on the pyrazole scaffold were adjusted to optimize inhibition of protein kina...

Bispecific antibodies show great promise as intrinsic combination therapies, but often suffer from poor physiochemical properties, many times related to poor heterodimerization. De Nardis et al. identify specific electrostatic interactions that facilitate efficient heterodimerization, resulting in bispecific antibodies with physiochemical properties very similar to those of naturally occurring ...

Introduction: Development of new pulp capping agents has paved the way towards the preservation of pulp vitality, which is an important goal in restorative dentistry. This study sought to assess the calcium ion release, pH and setting of mineral trioxide aggregate (MTA) Angelus, an experimental formulation of nano-hybrid MTA containing nano-SiO2, nano-Al2O3 and nano-TiO2 and MTA Angelus plus na...
