Prospective non-randomized comparison of transurethral laser en bloc resection vs. conventional resection of bladder tumors larger than 3 cm.

Background: En bloc resection of bladder tumor (ERBT) is an established surgical treatment method for patients with non-muscle invasive bladder cancer (NMIBC) in tumors less than 3 cm. Data regarding the efficacy and safety of ERBT on larger than 3 cm tumors are sparse and its efficacy compared to conventional transurethral resection (TURBT) remains unclear. The aim of this study was to prospectively compare the feasibility, safety and oncological outcomes of laser (Tm-fiber) ERBT and TURBT in patients with primary bladder lesions ≥3 cm.

Cyclic Stability of Two-Way Shape Memory Effect in Aged NiTiHf Polycrystals after Various Thermomechanical Treatments.

In the present paper, the cyclic stability of the high-temperature two-way shape memory effect was studied in high-strength NiTiHf polycrystals after various thermomechanical treatments-training (thermocycling under stress) and stress-induced martensite aging. The effect of training and stress-induced martensite aging on the microstructure, the two-way shape memory effect, and its cyclic stability was determined. It was found out that both thermomechanical treatments induce the high-temperature two-way shape memory effect at T > 373 K, with a strain of 1.

The Influence of Medium on Fluorescence Quenching of Colloidal Solutions of the Nd: LaF Nanoparticles Prepared with HTMW Treatment.

An original method was proposed to reduce the quenching of the NIR fluorescence of colloidal solutions of 0.1 at. % Nd: LaF nanoparticles (NPs) synthesized by aqueous co-precipitation method followed by hydrothermal microwave treatment.

Compulsive Eating in a Rat Model of Binge Eating Disorder Under Conditioned Fear and Exploration of Neural Mechanisms With mRNA Expression.

Compulsive eating is the most obstinate feature of binge eating disorder. In this study, we observed the compulsive eating in our stress-induced binge-like eating rat model using a conflicting test, where sucrose and an aversively conditioned stimulus were presented at the same time. In this conflicting situation, the binge-like eating prone rats (BEPs), compared to the binge-like eating resistant rats (BERs), showed persistent high sucrose intake and inhibited fear response, respectively, indicating a deficit in palatability devaluation and stronger anxiolytic response to sucrose in the BEPs.

Stable Aqueous Colloidal Solutions of Nd: LaF Nanoparticles, Promising for Luminescent Bioimaging in the Near-Infrared Spectral Range.

Two series of stable aqueous colloidal solutions of Nd: LaF single-phase well-crystallized nanoparticles (NPs), possessing a fluorcerite structure with different activator concentrations in each series, were synthesized. A hydrothermal method involving microwave-assisted heating (HTMW) in two Berghof speedwave devices equipped with one magnetron (type I) or two magnetrons (type II) was used. The average sizes of NPs are 15.
