Toxicity of Carbon, Silicon, and Metal-Based Nanoparticles to Sea Urchin Strongylocentrotus Intermedius.

With the increasing annual production of nanoparticles (NPs), the risks of their harmful influence on the environment and human health are rising. However, our knowledge about the mechanisms of interaction between NPs and living organisms is limited. Prior studies have shown that echinoderms, and especially sea urchins, represent one of the most suitable models for risk assessment in environmental nanotoxicology.

[Screening procedures in detection of oncological pathology in men].

The incidence of malignant neoplasms in men is higher versus women residing in Maritime Territory; neoplasms of the urogenital system account for an essential portion (13.6%) of all discussed diseases. Reduced funding to patient-care facilities, worse provision of hospitals and clinics with practitioners and paramedical personnel and minimal logistics supplies to medical facilities are the main causes that affect the quality of oncological medical care rendered to residents of Maritime Territory.

[Analgesia and intensive therapy during hemicorporectomy].

The first successful hemicorporectomy performed in this country is described. Clinical data are presented and specific features of anesthesia, infusion-transfusion therapy and management of the postoperative period are reviewed in detail.

[Analgesia and intensive therapy in single-step, combined and complex operations].

300 single-step, combined and complex operations have been performed to patients aged 16 to 82 years in the Institute of Proctology, USSR Ministry of Public Health, over the last 10-year period. Surgery was performed under various types of endotracheal combined analgesia: NLA, NLA in combination with halothane or calypsol. Arterial hypotension (short-term BP decrease by more than 40% baseline) was found in 29 patients (9.
