BACKGROUND Esthetic dental treatment for young adults can be challenging. Practitioners often use direct composite bonding in children and teenagers, and often it serves them for many years. However, direct composite bonding has its limitations (such as staining and chipping), and bonded porcelain often is needed. CASE DESCRIPTION The authors describe an 18-year-old woman who sought esthetic ...

objective(s): the role of aluminum (al) in the pathogenesis of neurodegenerative diseases has been implicated in several studies. however, the exact mechanisms of cytotoxic effects of al have not been elucidated yet. the aim of this study was to investigate the effect of l-type calcium channel antagonist, nimodipine (nm), and lithium chloride (licl) on al-induced toxicity in pc12 cells. materia...

background the development of drug delivery systems has improved the therapeutic and toxic properties of existing drugs in therapy. microemulsion systems are novel vehicles for drug delivery, which have been developed in recent years. these systems are currently of interest to the pharmaceutical scientist because of their considerable potential to act as drug delivery vehicles by incorporating ...

The asymmetric unit of the title compound, [Li(C8H6N2O4)(H2O)] n , comprises three Li cations, two of which are located on a twofold rotation axis, two carboxylate anions and three water mol-ecules, of which two are situated on the twofold rotation axis being aqua ligands. Both carboxylate anions are in μ2-bridging mode. All Li ions show a trigonal-bipyramidal coordination mode; the two located...

We theoretically explored new two-dimensional materials near the ionic instability (three-dimensional structures are favored), with covalent bonded systems (graphene) sitting at the opposite end of the spectrum. Accordingly, monolayer alkaline earth and transition metal halides, many of their bulk forms being layered structures, were investigated by density functional calculations. We thus pred...

Pyrolusite (β-MnO 2 ) was investigated for potential use in energy storage devices due to its promising properties cathode materials rechargeable lithium-ion batteries. A combination of evolutionary algorithm search techniques and density functional theory were used determine the structural stabilities β-MnO nanoclusters on landscape. However, pyrolusite suffers from some defects impurities tha...

lithium and valproate modulate disturbances in intracellular calcium homeostasis implicated in the pathophysiology of bipolar disorder, but the molecular mechanisms are not fully understood. two subtypes of transient receptor potential (trp) channel family, i.e. trpc3 and trpm2, are potential candidates involved in calcium signaling and implicated in the pathophysiology of bipolar disorder. thi...

one of the most important and serious disorders of gastrointestinal tract is acute pancreatitis which in severe form is associated with high mortality rate particularly in the presence of systemic inflammatory response and multiple organ failure. apoptosis linked to oxidative stress has been shown in the pancreas of the patients with acute pancreatitis. lithium, one of the most effective drugs ...

INTRODUCTION This article presents a 6-month case report and an in vitro evaluation of the performance of the new self-etching glass-ceramic monobond etch and prime (MEP) when applied in a lithium disilicate (LD). The MEP contains in the same bottle, along with acid conditioner and silanes. This simplifies the bonding procedures by reducing not only the number of steps, but also the working tim...
