Background

AZD2014 is a novel, potent and highly selective dual inhibitor of the mammalian rapamycin (mTORC1 and mTORC2) with an IC50 value of 2.8 nM. It is an oral inhibitor and possesses potential antineoplastic activity.

AZD2014 enhanced susceptibility of glioblastoma stem-like cells (GSCs) to irradiation both in vitro and under orthotopic in vivo conditions. Kahn J et al pretreated CD133+ and CD15+ GSC cells with AZD2014 (2 μM) for 1 hour, followed by irradiation. The effect was then measured by clonogenic survival analysis [2]. Using in vitro screening, they demonstrated that the combination of ibrutinib, an inhibitor of the tyrosine kinase BTK, and AZD2014 could dramatically induce apoptosis in ABC-subtype DLBCL cell lines. Thereby, the combination of AZD2014 with a BTK inhibitor is a promising therapeutic method to cure patients with ABC-type DLBCL [3]. In hepatocellular carcinoma cells, AZD2014 gave rise to a more complete inhibition of mTORC1 than rapamycin, while the inhibition of mTORC2 prevented the feedback activation of AKT signaling. Therefore, AZD2014 was identified to be more efficacious in the induction of apoptosis, autophagy, and cell cycle arrest, resulting in a significant proliferation suppression of the cells, in contrast with rapamycin [4].

In a recent human pharmacokinetic and pharmacodynamic study, a dose of 50mg BD(twice a day)AZD2014 was recommended to achieve pharmacologically relevant plasma concentrations [5]. References:

1. Effect of Hydrofluoric Acid Concentration and Etching Time on Bond Strength to Lithium Disilicate Glass Ceramic. Oper Dent. 2017 Nov/Dec;42(6):606-615. doi: 10.2341/16-215-L. Epub 2017 Jul 14. PMID:28708007 Abstract

The aim of this study was to evaluate the influence of different concentrations of hydrofluoric acid (HF) associated with varied etching times on the microshear bond strength (μSBS) of a resin cement to a lithium disilicate glass ceramic. Two hundred seventy-five ceramic blocks (IPS e.max Press [EMX], Ivoclar Vivadent), measuring 8 mm × 3 mm thickness, were randomly distributed into five groups according to the HF concentrations (n=50): 1%, 2.5%, 5%, 7.5%, and 10%.

BACKGROUND: This study evaluated the surface morphology, chemical composition and adhesiveness of lithium disilicate glass ceramic after acid etching with hydrofluoric acid or phosphoric acid.METHODS: Lithium disilicate glass ceramic specimens polished by 600-grit silicon carbide paper were subjected to one or a combination of these surface treatments: airborne particle abrasion with 50-μm alumina (AA), etching with 5% hydrofluoric acid (HF) or 36% phosphoric acid (Phos), and application of silane coupling agent (Si). 3. Fatigue failure load of feldspathic ceramic crowns after hydrofluoric acid etching at different concentrations. J Prosthet Dent. 2018 Feb;119(2):278-285. doi: 10.1016/j.prosdent.2017.03.021. Epub 2017 May 26. PMID:28552291 Abstract

STATEMENT OF PROBLEM: Hydrofluoric acid etching modifies the cementation surface of ceramic restorations, which is the same surface where failure is initiated. Information regarding the influence of hydrofluoric acid etching on the cyclic loads to failure of ceramic crowns is lacking.PURPOSE: The purpose of this in vitro study was to evaluate the influence of different hydrofluoric acid concentrations on the fatigue failure loads of feldspathic ceramic crowns.
