Ibrutinib is a first-in-class, once-daily inhibitor of Bruton's tyrosine kinase, an enzyme implicated in growth and survival of MM cells. Preclinical data suggest supra-additivity or synergy between ibrutinib and proteasome inhibitors (PIs) against MM. This phase 1/2b study evaluated the efficacy and safety of ibrutinib plus the PI carfilzomib and dexamethasone in patients with relapsed/refractory MM (RRMM). In this final analysis, we report results in patients who received the recommended phase 2 dose (RP2D; ibrutinib 840 mg and carfilzomib 36 mg/m2 with dexamethasone), which was determined in phase 1. The primary efficacy endpoint was overall response rate (ORR). Fifty-nine patients with RRMM received the RP2D (18 in phase 1 and 41 in phase 2b). These patients had received a median of three prior lines of therapy; 69% were refractory to bortezomib, and 90% were refractory to theithors.

However, the covalent chemistry of this kind of 2D materials is still barely explored. see more Herein, we report the covalent functionalization with silanes of a magnetic NiFe-LDH. The synthetic route consists of a topochemical approach followed by the anion exchange reaction of a surfactant molecules prior to the covalent functionalization with the (3-aminopropyl)triethoxysilane (APTES) molecules. The functionalized NiFe-APTES was fully characterized using X-ray diffraction, infrared spectroscopy, electron microscopy, thermogravimetric analysis coupled with mass spectrometry and 29Si solid state nuclear magnetic resonance, among others. The effect on the electronic properties of the functionalized LDH was studied by a magnetic study in combination with Mössbauer spectroscopy. Moreover, the reversibility of the silane-functionalization at basic pH was demonstrated, and the quality of the resulting LDH proved by studying the electrochemical performance in the oxygen evolution reaction in basic media. Furthermore, the anion exchange capability for the NiFe-APTES was tested employing Cr(VI), resulting in an increase of 200 % of the anion retention. This report allows a new level in the tunability of LDHs opening the door to the synthesis of new hybrid materials and architectures. © 2020 WILEY-VCH Verlag GmbH & Co.

Magnetic and optical actuation methods are the most widely used actuation methods in mobile microrobotics currently, in addition to acoustic and biological (cell-driven) actuation approaches. The pros and cons of these actuation methods are reported here, depending on the given context. They can both enable long-range, fast, and precise actuation of single or a large number of microrobots in diverse environments. Magnetic actuation has unique potential for medical applications of microrobots inside nontransparent tissues at high penetration depths, while optical actuation is suitable for more biotechnology, lab-/organ-on-a-chip, and desktop manufacturing types of applications with much less surface penetration depth requirements or with transparent environments. Combining both methods in new robot designs can have a strong potential of combining the pros of both methods. There is still much progress needed in both actuation methods to realize the potential disruptive applications of mobile microrobots in real-world conditions. © 2020 The Authors.

However, the air/water instability of the high-reactive Li metal remains unsolved. Here, a water-stable Li metal anode with ultrahigh-rate capability enabled by a rationally designed architecture is reported. A hydrophobic graphene framework, consists of an array of vertically aligned sheets and a roof of sloping-aligned sheets, is utilized to fully host lithium metal. As a result, it is first demonstrated that the composite Li metal anode can run stably even after it directly contacts with water. In addition, both the arrays and the roof in the framework are directional graphene microsheets that can provide fast charge transport kinetics in the anode without tortuosity. Therefore, the anode can operate at an extremely high current density of 50 mA cm-2 with long-term cycling stability. Importantly, the composite Li anodes in Li||LiFePO4 and Li||NCM-811 cells also show much improved performances than Li metal foil under crucial conditions of lean electrolyte and low negative/positive capacity ratio. This design provides a significant stride in the safety toward the practicability of low air/water tolerance materials. © 2020 WILEY-VCH Verlag GmbH & Co.

OI is a genetically heterogeneous disorder that most commonly arises from dominant mutations in genes encoding type I collagen (COL1A1 and COL1A2). In addition, OI is recessively inherited with the majority of cases resulting from mutations in prolyl-3-hydroxylation complex members, which includes cartilage-associated protein (CRTAP). OI patients are at an increased risk of fracture throughout their lifetimes. However, non-union or delayed healing has been reported in 24% of fractures and 52% of osteotomies. Additionally, refractures typically go unreported, making the frequency of refractures in OI patients unknown. Thus, there is an unmet need to better understand the mechanisms by which OI affects fracture healing. Using an open tibial fracture model, our study demonstrates delayed healing in both Col1a2 G610c/+ and Crtap -/- OI mouse models (dominant and recessive OI, respectively) that is associated with reduced callus size and predicted strength.
