Predictive Value of Flank Pain and Gross Hematuria on Long-Term Survival in Patients With Upper Tract Urothelial Carcinoma Treated by Radical Nephroureterectomy.

Background: Assessing the prognosis preoperatively in patients with upper tract urothelial carcinoma (UTUC) remains a challenge for urologists. Gross hematuria (GH) and flank pain (FP) are the 2 most common and easily perceived symptoms of UTUC. Therefore, we aimed to investigate the prognostic values of GH and FP in patients with UTUC after undergoing radical nephroureterectomy (RNU).

Exosome-Mediated miR-4792 Transfer Promotes Bladder Cancer Cell Proliferation via Enhanced FOXC1/c-Myc Signaling and Warburg Effect.

Bladder cancer is the second-most common malignancy in the urogenital system and the most common in men. However, our understanding of the driving mechanisms of bladder cancer remains incomplete. The forkhead box (FOX) family of transcription factors is implicated in urogenital development and bladder malignancies.

Metal-organic framework derived hollow porous CuO-CuCoO dodecahedrons as a cathode catalyst for Li-O batteries.

Herein, hollow porous CuO-CuCoO dodecahedrons are synthesized by using a simple self-sacrificial metal-organic framework (MOF) template, which resulted in dodecahedron morphology with hierarchically porous architecture. When evaluated as a cathodic electrocatalyst in lithium-oxygen batteries, the CuO-CuCoO composite exhibits a significantly enhanced electrochemical performance, delivering an initial capacity of 6844 mA h g with a remarkably decreased discharge/charge overpotential to 1.15 V ( Li/Li) at a current density of 100 mA g and showing excellent cyclic stability up to 111 charge/discharge cycles under a cut-off capacity of 1000 mA h g at 400 mA g.

MXene-supported CoO quantum dots for superior lithium storage and oxygen evolution activities.

A novel hybrid, composed of Co3O4 quantum dots supported on Ti3C2Tx (MXene) nanosheets, exhibits a strong synergetic effect, and shows superior lithium storage (capacity = 766.5 mA h g-1 at 2 A g-1 after 400 cycles) and oxygen evolution (overpotential = 340 mV at 10 mA cm-2) activities.

Ultrathin MXene Nanosheets Decorated with TiO Quantum Dots as an Efficient Sulfur Host toward Fast and Stable Li-S Batteries.

Being conductive and flexible, 2D transition metal nitrides and carbides (MXenes) can serve in Li-S batteries as sulfur hosts to increase the conductivity and alleviate the volume expansion. However, the surface functional groups, such as OH and F, weaken the ability of bare MXenes in the chemisorption of polysulfides. Besides, they create numerous hydrogen bonds which make MXenes liable to restack, resulting in substantial loss of active area and, thus, inaccessibility of ions and electrolyte.

Smartly Designed Hierarchical MnO @Fe O /CNT Hybrid Films as Binder-free Anodes for Superior Lithium Storage.

Nowadays, the development of advanced anode materials is highly desirable for the increasing demand for high-performance lithium-ion batteries (LIBs). Nanostructured MnO has received utmost attention due to high theoretical capacity (1230 mA h g ), abundant resources, environmental benignity, and shortened electron and ion diffusion paths. Unfortunately, poor electronic conductivity and strong aggregation inclination of MnO nanostructures result in disappointing electrochemical performances, which restrict their practical application as sole institute.

Dandelion-like CoO mesoporous nanostructures supported by a Cu foam for efficient oxygen evolution and lithium storage.

Novel dandelion-like Co3O4 mesoporous nanostructures, supported by a Cu foam, are prepared by a combination of hydrothermal synthesis and annealing.
