[The modern concept of anesthesiological provision of surgical interventions in geriatric patients with diseases of the hand and forearm].

The article analyzes literature data on the characteristics of local anesthetics used to perform regional anesthesia, and provides a detailed assessment of the drug "Articaine". The article presents the results of an open randomized study of the action of the anesthetics "Articaine-Binergia" 20 mg/ml and "Ropivocaine" used to perform conduction anesthesia in upper limb surgeries. The results of the study demonstrated a high degree of effectiveness of both drugs, but the safety indicators of the drug "Articaine-Binergia" 20 mg/ml significantly exceeded those of "Ropivocaine".

Proton conductivity of fluorite based rare earth titanates (LnTi)O (Ln = Yb, Er, Ho, 0.667 ≤ ≤ 0.765).

Solid solutions of rare earth titanates with high contents of rare earth oxides of up to 50-62% have been synthesized by the co-precipitation method and their structure, microstructure and conductivity in dry and wet air have been studied. Proton conductors have been found for the first time in solid solutions of rare earth titanates with a high content of LnO (>50%) with a nominal formula composition of (LnTi)O (Ln = Yb, Er, Ho, 0.667 ≤ ≤ 0.

Nitrogen-Doped Carbon Nanodots Produced by Femtosecond Laser Synthesis for Effective Fluorophores.

Understanding the effect of heteroatom doping is crucial for the design of carbon nanodots (CNDs) with enhanced luminescent properties for fluorescence imaging and light-emitting devices. Here, we study the effect and mechanisms of luminescence enhancement through nitrogen doping in nanodots synthesized by the bottom-up route in an intense femtosecond laser field using the comparative analysis of CNDs obtained from benzene and pyridine. We demonstrate that laser irradiation of aromatic compounds produces hybrid nanoparticles consisting of a nanocrystalline core with a shell of surface-bonded aromatic rings.

[Magnetic resonance imaging in diagnosis of localized prostatic cancer].

To evaluate efficacy of MR imaging (MRI) in diagnosis of local prostatic cancer (LPC) and validity of MRI performance in patients with high levels of prostate-specific antigens (PSA), we made a retrospective analysis of a combined examination of 210 patients including MRI (100%). Of them, 68 (32.4%) had prostatic cancer (LPC pT1-pT2 in 27 patients, 39.

[Potentialities of low-field magnetic resonance tomography in the diagnosis and treatment of invasive cancer of cervix uteri].

Unlabelled: The aim of the study was to evaluate the efficiency of low-field (0.14 T) magnetic resonance imaging (MRI) in the diagnosis and treatment of cancer of the cervix uteri.

Materials And Methods: Low-field MRI was performed in 39 patients with cancer of the cervix uteri to define the stage of the tumor and to follow up the outcomes of their treatment.
