Objectives. To investigate if reducing the light-curing time (while maintaining similar energy density) of resin-based surface sealants influences their erosion-preventive potential and mechanical stability after thermomechanical loading. Methods. Dentine samples were treated as follows: group 1-untreated, groups 2-4-Seal&Protect, groups 5-7-experimental sealer, and groups 8-10-Syntac Classic s...
Combination antiemetic therapy has become common practice for the prevention of nausea and vomiting caused by anticancer drugs. In this study, we investigated the stability of azasetron hydrochloride 0.1 mg/mL plus dexamethasone sodium phosphate 0.05, 0.1, or 0.2 mg/mL in 0.9% sodium chloride injection and stored in polyolefin bags and glass bottles over a period of 14 days at 4°C and 48 hours ...
Bispecific antibodies enable unique therapeutic approaches but it remains a challenge to produce them at the industrial scale, and the modifications introduced to achieve bispecificity often have an impact on stability and risk of immunogenicity. Here we describe a fully human bispecific IgG devoid of any modification, which can be produced at the industrial scale, using a platform process. Thi...
Ligand cross-linking is known to improve the colloidal stability of nanoparticles, particularly in aqueous solutions. However, most cross-linking is performed chemically, in which it is difficult to limit interparticle cross-linking, unless performed at low concentrations. Photochemical cross-linking is a promising approach but usually requires ultraviolet (UV) light to initiate. Using such hig...
We study optical bistability of stationary light transmission in nonlinear periodic structures of finite and semi-infinite length. For finite-length structures, the system exhibits instability mechanisms typical for dissipative dynamical systems. We construct a LeraySchauder stability index and show that it equals the sign of the Evans function in λ = 0. As a consequence, stationary solutions w...
Post-translational regulation of protein abundance in cells is a powerful tool for studying protein function. Here, we describe a novel genetically encoded protein domain that is degraded upon exposure to nontoxic blue light. We demonstrate that fusion proteins containing this domain are rapidly degraded in cultured cells and in zebrafish upon illumination.
The electronic stability program (ESP) is increasingly finding acceptance in vans and light commercial vehicles (LCV). Nearly all current models, whose gross vehicle weight is generally between 2.8 and 7.5 metric tons, are now available with this active safety system, either as an option or even as standard equipment. Many studies have now confirmed that ESP can prevent a vehicle from skidding ...
this study investigates the problem of translating religious allusions in persian literature, namely the ones borrowed from quranic verses and hadiths. the purpose of this study is to shed light on how different translators dealt with such a task and also to provide guidelines for translators in coping with religious allusions.
The visual system plays a fundamental role in dynamic stability control. During walking, the visual deprivation induces changes in spatiotemporal parameters: decrease of gait speed, decrease of step length and increase of double stance time [1, 2]. These patterns are adopted to maintain a cautious gait pattern. However, adults apparently have a well defined motor behavior that enables overcome ...
Light chain (AL) amyloidosis is a devastating disease characterized by amyloid deposits formed by immunoglobulin light chains. Current available treatments involve conventional chemotherapy and autologous stem cell transplant. We have recently concluded a phase III trial comparing these two treatments. AL amyloidosis patients who achieve hematological complete response (CR) do not necessarily a...
