Same-day bilateral total knee arthroplasties (BTKAs) are associated with increased complications compared with staged procedures; however, as complication rates and lengths of stay (LOS) for same-day procedures decrease, they may become attractive alternatives to staged procedures. The void of recent nationwide studies comparing the 30-day total cost and risks of these procedures inspired this propensity matched review. Therefore, we compared 30-day outcomes in staged and same-day BTKAs occurring in 2016 and 2017 using the National Readmission Database (NRD), a nationwide database. Read More

Coalescence of droplets containing nanoparticles has been paid much attention to fabricate functional photonic crystal (PC) patterns. However, most of them focus on the coalescence of droplets containing the same nanoparticles. Nowadays, an active challenge comes from the coalescence of droplets containing different nanoparticles due to the spontaneous mutual diffusion of different nanoparticles between coalescing miscible droplets driven by the released Gibbs free energy.

Magnetic nanoparticles offer a unique potential for various biomedical applications, but prior to commercial usage a standardized characterization of their structural and magnetic properties is required. For a thorough characterization, the combination of conventional magnetometry and advanced scattering techniques has shown great potential. In the present work, we characterize a powder sample of high-quality iron oxide nanoparticles that are surrounded with a homogeneous thick silica shell by DC magnetometry and magnetic small-angle neutron scattering (SANS).

A rhodamine B-based sensor (RS) was designed and synthesized by a combination of the spirolacton rhodamine B (fluorophore) and multidentate chelates (ionophore) with high affinity towards Hg. In the presence of Hg, the resulting red-orange fluorescence (under UV light) and naked eye red color of RS are supposed to be used for quantitative and qualitative measurement of Hg. Further fluorescent titration and analysis demonstrate that RS can selectively detect Hg within 1 s with a low limit of detection (LOD) of 16 nM in acetonitrile media, meanwhile, the association constant (K) was calculated to be 0.

The self-microemulsifying delivery system was fabricated by whey protein isolate (WPI), daidzein (Dai) and surfactants, the interaction of WPI, Dai and D-α-Tocopherol polyethylene glycol succinate (TPGS) was hereby studied in the absence or presence of Tween 20. The increase of surfactant concentration led to the decrease of the modulus and changes of protein interfacial conformation, which allowed the formation of a strong intermolecular network. The environment and structure of WPI and daidzein could be changed by TPGS, and the addition of Tween 20 could further enhance the interaction between the components by changing TPGS structure.

The demand for the development of fast, easy-to-use and low-cost analytical methods for food adulteration analysis has being increasing in the last years. Although infrared spectroscopic techniques offer these advantages, the validation of screening methods requiring the application of multivariate data treatment is less frequently described in literature thus limiting their use as routine tools in control laboratories for food fraud monitoring. In this paper, an EU-validation procedure for screening methods was successfully applied to a multivariate FT-NIR spectroscopic method for the screening of durum wheat pasta samples adulterated with common wheat at the screening target concentration of 3%.

The sensory qualities and shelf life of tea beverage strongly affected by tea cream that forms by the interaction of polyphenols and protein. The study aimed to investigate the effects of the interactions between tea polyphenols (TPs) and bovine serum albumin (BSA) on tea cream formation at different concentrations. The tea cream formation increased with TPs and BSA concentration increased. Read More
