Pediatric head and neck cancers account for overall 12% of all pediatric cancers. Despite recent advances in therapeutic modalities, children with tumor metastasis have poor prognosis. Therefore, there is an unmet need for new and effective treatment modalities for pediatric head and neck cancers. The present study describes a simple and efficient method for fabrication of cationic lipid‑polymer hybrid nanoparticles (CLPNs) for co‑delivery of cisplatin (CDDP) and DNA (CDDP/DNA CLPNs) for the therapy of childhood head and neck cancers...

Pancreatic neuroendocrine neoplasms (pNENs) are rare tumors accounting for only 1%-2% of all pancreatic tumors. pNENs are pathologically heterogeneous and are categorized into three groups (neuroendocrine tumor: NET G1, NET G2; and neuroendocrine carcinoma: NEC) on the basis of the Ki-67 proliferation index and the mitotic count according to the 2010 World Health Organization (WHO) classification of gastroenteropancreatic NENs. NEC in this classification includes both histologically well-differentiated and poorly differentiated subtypes, and modification of the WHO 2010 classification is under discussion based on genetic and clinical data...

The structurally complex oligomeric proanthocyanidins (OPACs) are promising biomimetic agents, capable of strengthening the macromolecular backbone of teeth via intermolecular and intermicrofibrillar cross-linking. This study establishes analytical methods capable of determining the absolute configuration of the catechin-type monomeric units of underivatized OPACs. This preserves the capacity of their biological evaluation, aimed at understanding the inevitably stereospecific interactions between the OPACs and dentin collagen...

Regulators of G protein signaling (RGS) proteins are celebrating the 20(th) anniversary of their discovery. The unveiling of this new family of negative regulators of G protein signaling in the mid-1990's solved a persistent conundrum in the G protein signaling field, in which the rate of deactivation of signaling cascades in vivo could not be replicated in exogenous systems. Since then, there has been tremendous advancement in the knowledge of RGS protein structure, function, regulation and their role as novel drug targets...

We present a new Janus structured catalyst consisting of Pt nanoparticles on Fe-N-C nanoparticles encapsulated by graphene layers for the ORR. The ORR activity of the catalyst increases under potential cycling as the unique Janus nanostructure is further bonded due to a synergetic effect. The present study describes an important advanced approach for the future design of efficient, stable, and low-cost Pt-based electrocatalytic systems.

Highlighted by the safe operation and stable performances, titanium oxides (TiO2) are deemed as promising candidates for next generation lithium-ion batteries (LIBs). However, the pervasively low capacity is casting shadow on desirable electrochemical behaviors and obscuring their practical applications. In this work, we reported a unique template-assisted and two-step atomic layer deposition (ALD) method to achieve TiO2@Fe2O3 core-shell nanotube arrays with hollow interior and double-wall coating. The as-prepared architecture combines both merits of the high specific capacity of Fe2O3 and structural stability of TiO2 backbone...

Colloids are valuable model systems to understand the structure and dynamics of matter, explore new self-assembly concepts, and realize advanced materials. Herein, we demonstrate social self-sorting of co-assembled families of colloids by orthogonal host/guest recognition using cyclodextrins. We show that mixtures of four partners self-sort into their respective families without mutual interference. Additionally, the self-assemblies and their interactions are switchable using orthogonal triggers. This study goes beyond previous features of molecular self-sorting, and opens the design space for future self-sorting colloidal systems via rationally designed molecular recognition...

Prasugrel is a third-generation thienopyridine that achieves potent platelet inhibition with less pharmacological variability than other thienopyridines. However, clinical experience suggests that prasugrel may be associated with a higher risk of de novo and recurrent bleeding events compared with clopidogrel in Japanese patients undergoing percutaneous coronary intervention (PCI). In this review, we evaluate the risk of bleeding in Japanese patients treated with prasugrel at the doses (loading/maintenance doses: 20/3...

Naveen S Basappa
Targeted therapy for metastatic renal cell carcinoma (mRCC) was introduced a decade ago and since then, a number of therapeutic options have been developed. Vascular endothelial growth factor-targeted therapy is the widely accepted first-line option for mRCC. After progression, treatment in the second-line setting has typically been with either axitinib or everolimus. However, with the advent of several new agents demonstrating efficacy in the second-line setting, including nivolumab, cabozantinib, and the combination of lenvatinib and everolimus, the treatment paradigm has shifted toward these novel therapies with improved patient outcomes...
