Dental amalgam fillings: An under-investigated source of mercury exposure [PDF]

, 2019
Dental amalgam fillings, which contain about 50% mercury, have been used since the early 19th century. However, their use has been controversial, particularly because they continually release small amounts of mercury.

Isolation of a californium(II) crown–ether complex

Nature Chemistry, 2023
The actinides, from californium to nobelium (Z = 98–102), are known to have an accessible +2 oxidation state. Understanding the origin of this chemical behaviour requires characterizing Cf^II materials, but investigations are hampered by the fact that ...

An efficient new route to dihydropyranobenzimidazole inhibitors of HCV replication. [PDF]

, 2010
A class of dihydropyranobenzimidazole inhibitors was recently discovered that acts against the hepatitis C virus (HCV) in a new way, binding to the IRES-IIa subdomain of the highly conserved 5' untranslated region of the viral RNA and thus preventing the

The use of Bioceramics as root-end filling materials in periradicular surgery: a literature review [PDF]

, 2018
Introduction: Periradicular surgery involves the placement of a root-end filling following root-end resection, to provide an apical seal to the root canal system. Historically several materials have been used in order to achieve this seal.
