A new and efficient approach to benzocycles from cyclopropene derivatives is described. Deprotection by organolithiums and subsequent ring-opening cyclization of the related 2-cyclopropenyl phenyl or benzyl acetates generated benzofurans and isochromenes in one pot. ...

A new application of lithium perchlorate-nitromethane (LPNM) for the formation of aromatic C-N and C-C bonds is introduced. LPNM-promoted reactions of anilines with diarylmethanols selectively generate N-alkylated anilines or mono and double Friedel-Crafts alkylation products under d...

Mass spectrometry imaging of lipids using MALDI-TOF/TOF mass spectrometers is of growing interest for chemical mapping of organic compounds at the surface of tissue sections. Many efforts have been devoted to the best matrix choice and deposition technique. Nevertheless, the identifi...

The aims of the study were to develop and test multi-phase glaze coatings for zirconia restorations, so that the surface could be etched and adhesively bonded. Zirconia disc specimens (n=125, 16 mm x 1 mm) were cut from cylinders of Y-TZP (yttria-stabilized tetragonal zirconia polycrystals) ZS-Blank...

We proposed that this reaction proceeded by the consecutive cyclization to aziridines via the SN2 process involving the activation of the C-Br bond based on the intermolecular Br…Li(+) coordination, as a result of studies of reaction mechanisms....

This is a short overview focusing on the biochemical interactions underlying the protective effects of lithium at the neuronal level. These include lithium modulation of autophagy, growth factors, excitotoxicity, and a variety of mechanisms underlying cell death, neurogenesis, and neuronal different...

We directly compared lamotrigine to lithium under conditions similar to clinical routine conditions. Adult bipolar I disorder patients with at least two episodes within the last five years and an index episode requiring treatment were randomized to lithium (n = 78; doses adjusted to...

We discuss the evidence in light of the complexity inherent in the connection between cognitive deficits and neurological abnormalities in BD. This article also addresses issues related to etiology, advancing an integration of neurological, clinical, cognitive, and psychosocial factors into a model...
