Composite suture material based on polylactide accelerates the healing of surgical wounds in in vivo experiment.

In laboratory conditions, composite sutures based on polylactide (PLA) containing chitin nanofibrils modified with polyethylene glycol (CN-PEG) and poviargol (silver nanoparticles stabilized with poly(N-vinylpyrrolidone)) were obtained, studied, and used as a prototype. Surgical sutures threads with the addition of CN-PEG have stable mechanical properties both in air and in a buffer simulating the environment of a living organism. The yield strength of oriented threads decreased by an average of 15%, whereas for non-oriented threads the decrease was 3-4 times.

[Analysis of indocyanine green plasma disappearance rate in clinical practice].

Objective: To justify the optimal method for determining indocyanine green plasma disappearance rate (PDR).

Material And Methods: We analyzed PDR in intensive care units. Indocyanine green was administered intravenously at a dose of 0.

[Activity of the Russian antitumor compound chlonisol in models of eyelid tumors (experimental study)].

Unlabelled: Eyelid tumors are the most common neoplasms in everyday ophthalmic practice and cover a wide range of benign and malignant lesions. Surgical methods, cryodestruction, laser therapy and radiation therapy are used in the treatment of malignant eyelid tumors. Chemotherapy does not occupy a prominent place in the treatment of malignant eyelid tumors, its use is limited to sensitive tumors.

Principles and Problems of Exosome Isolation from Biological Fluids.

Exosomes, the subclass of small membrane extracellular vesicles, have great diagnostic and therapeutic potential, but the lack of standardized methods for their efficient isolation and analysis limits the introduction of exosomal technologies into clinical practice. This review discusses the problems associated with the isolation of exosomes from biological fluids, as well as the principles of traditional and alternative methods of isolation. The aim of the presented review is to illustrate the variety of approaches based on the physical and biochemical properties of exosomes that can be used for exosome isolation.

[The lifespans of scholars referred to different disciplines according to data from diverse sources: Inferences and challenges.].

Human lifespan is known to correlate positively with education level. In the present paper, it is explored whether there are significant differences in lifespan among those whose education may be reasonably rated as the highest possible, i.e.

Evaluation of the Accuracy of Standardized Uptake Values of F-fluorodeoxyglucose in Lung Lesions Based on Phantom Studies.

Unlabelled: was to estimate the accuracy of standardized uptake values of F-fluorodeoxyglucose (F-FDG) in lung lesions during positron emission tomography combined with computed tomography (PET/CT) imaging, based on phantom studies performed for different PET/CT scanners.

Materials And Methods: The analysis of the PET/CT with F-FDG data was performed for 86 patients newly diagnosed with the lung lesions: malignant tumors (n=37), benign tumors and inflammatory diseases (n=49). The criteria for inclusion in the study were developed considering the recommendations of the Fleischner Society (2017).

The presence of polymorphisms in genes controlling neurotransmitter metabolism and disease prognosis in patients with prostate cancer: a possible link with schizophrenia.

Polymorphisms of neurotransmitter metabolism genes were studied in patients with prostate cancer (PC) characterized by either reduced or extended serum prostate-specific antigen doubling time (PSADT) corresponding to unfavorable and favorable disease prognosis respectively. The 'unfavorable prognosis' group (40 cases) was defined by PSADT ≤ 2 months, whereas patients in the 'favorable prognosis' group (67 cases) had PSADT ≥ 30 months. The following gene polymorphisms known to be associated with neuropsychiatric disorders were investigated: a) the STin2 VNTR in the serotonin transporter gene; b) the 30-bp VNTR in the monoamine oxidase A gene; c) the Val158Met polymorphism in the catechol-ortho-methyltransferase gene; d) the promoter region C-521T polymorphism and the 48 VNTR in the third exon of the dopamine receptor gene.

[Clinical aspects of asymptomatic arrhythmia in elderly patients with left breast cancer at the stage of radiation therapy.].

Insufficient knowledge age peculiarities of the clinical course of cardiac arrhythmias occurring asymptomatically as a manifestation of cardiotoxicity in women with breast cancer at the stage of radiation therapy, determines the high demand for research on this problem. The aim of the study was to identify and evaluate asymptomatic cardiac arrhythmias in elderly women with left breast cancer at the stage of radiation therapy. 48 women without a history of severe cardiovascular disease with HER2neu negative cancer of the left breast at the stage of 3D conformal radiotherapy were examined.

Melatonin increases overall survival of prostate cancer patients with poor prognosis after combined hormone radiation treatment.

Background: The antitumor and immunomodulating activities of melatonin are widely known. These activities are based upon the multifactorial mechanism of action on various links of carcinogenesis. In the present paper, the long-term results of the clinical use of melatonin in the combined treatment of patients with prostate cancer of various risk groups were evaluated.

[Longevity and some reasons of death of musicians of the XX century.].

Data on lifespan and some reasons of musicians' death of the XX century are presented in this article. The mean age of death (MAD) in male musicians (n=20 218) was 67,8 years, whereas the MAD in female ones was 71,5 years. «Classic» musicians both men and women lived longer than jazz, pop and variety music performing musicians (6,3 and 9,7 years longer respectively) and much longer then rock musicians (21,7 and 30,7 years longer, respectively).
