[Surgery for abdominal neuroblastoma in children]. / Khirurgiya neiroblastomy abdominal'noi lokalizatsii u detei.

This review is devoted to surgical approach for neurogenic tumors in children. The authors discuss epidemiological data, history of surgical approaches, preoperative imaging and risk factors. A special attention is paid to the influence of surgical interventions for various neuroblastomas on overall and event-free survival in pediatric population, as well as the most common surgical complications and modern approaches to their treatment.

[Autologous kidney transplantation in a high-risk patient with locally advanced retroperitoneal neuroblastoma]. / Autologicheskaya transplantatsiya pochki u patsienta s mestnorasprostranennoi neiroblastomoi zabryushinnogo prostranstva gruppy vysokogo riska. Klinicheskoe nablyudenie.

Surgery of locally advanced neuroblastoma with risk factors is one of the most difficult in pediatric surgery. Incidence of nephrectomy during subtotal or complete tumor resection is higher due to common involvement of renal vessels. We present a patient with locally advanced retroperitoneal neuroblastoma who underwent heterotopic kidney autotransplantation.

High-resolution large-scale plasmonic laser color printing for jewelry applications.

We offer to use optical features of surface plasmon resonance in Ag nanoparticles for jewelry application as a method for the well-controlled decoration of silver items. The novel approach of silver nanoparticles formation with sizes from 5 to 50 nm via nanosecond direct laser writing allows for controlling the reflectance spectra, thus creating a color image on precious metals with a high resolution of about 450 dpi without dyes or hazardous chemicals. Moreover, the large-scale color image can be applied in single-step processing with significant productivity of 2 cm2 per minute. This work opens a strong direction for the practical application in the jewelry industry, art, and coining.

Controlled nanostructures formation on stainless steel by short laser pulses for products protection against falsification.

The coloration of stainless steel surface due to the formation of spatially periodic structures induced by laser pulses of nanosecond duration is demonstrated. The period of microstructures corresponds to the laser wavelength, and their orientation angle depends on the adjustment of laser polarization. The marking algorithm for the development of authentication patterns is presented. Such patterns provide several levels of protection against falsification (visual, colorimetric and structural) along with high recording speed and capability of automated reading.

[Possibility of using DST-30 thermoelastoplast in blood transfusion systems]. / Issledovanie vozmozhnosti primeneniia termoélastoplasta DST-30 v sistemakh perelivaniia krovi.

Investigating possible application of the DCT-30 thermoelastoplastic shows advantages of some physico-technical properties of this product based on natural caoutchouc and latex by comparison with base-rubber onene. It justifies recommending the former for making injection tubes in the blood transfusion systems.
