Cancer is one of the leading causes of death worldwide. Despite substantial progress in the understanding of tumor biology, and the appearance of new generations of targeted drugs and treatment techniques, the success achieved in this battle, with some notable exceptions, is still only moderate. Photodynamic therapy (PDT) is a successful but still underestimated therapeutic modality for treating many superficial cancers.

In order to improve the treatment of superficial bladder tumors, we evaluated the efficacy and safety of transurethral resection (TURB) followed by fluorescence diagnosis (FD) and photodynamic therapy (PDT) with chlorin e photosensitizers (PSs), . "Fotoran e" and "Fotoditazin".

A practical advantage of the dyads is the possibility to tune its CS process by the porphyrin periphery modification, which allows one to optimize the dyad for particular applications. However, this tuning process is typically composed of a series of trial stages involving the development of complex synthetic schemes.

However, the assessment of antiarrhythmic properties of BoNT has so far been limited, relying exclusively on vagal stimulation and rapid atrial pacing models. The present study examined the antiarrhythmic effect of specially formulated BoNT/A1-chitosan nanoparticles (BTN) in calcium chloride-, barium chloride- and electrically induced arrhythmia rat models.

Objective: The purpose of this study was to report 3-year AF patterns by the use of implantable cardiac monitors (ICMs).
Methods: Sixty patients with a history of paroxysmal AF and indications for CABG were randomized 1:1 to either BTX or placebo injections into 4 posterior epicardial fat pads.
Aim: To clarify the etiology of nosocomial UTIs occurring in the urology departments and the outpatient clinic of the Ivanovo Regional Clinical Hospital (IvRCH), to develop recommendations on the empirical use of antibiotic therapy.
Materials And Methods: Bacterial composition of urine in urological patients was monitored from 1999 to 2015. The sensitivity of the pathogens to the main antibacterial agents was determined using the Kirby-Bauer disk diffusion susceptibility test.
Botulinum neurotoxin (BoNT) is used for an increasing number of neurological and non-neurological indications and disorders. Since the duration of action of this neurotoxin is limited, the goal of the work was to improve the pharmacological time course of BoNT. We explored the effect of several polysaccharides on the duration of action of BoNT/A1 in rat electromyography.

Materials And Methods: Stone mineralogical composition, 24 hour biochemistry and pH-profile of urine were examined for sixty four stone formers using powder X-ray diffraction, spectrophotometric and potentiometric techniques.
Results: The analysis indicated that 44 % of calculi were composed of pure calcium oxalate monohydrate, whereas other 56 % contained both monohydrate and dihydrate or usually their mixtures with hydroxyl apatite.
Aim: To identify the most likely metabolic disturbances and risk factors for stone formation in a group of patients with calcium oxalate urolithiasis, and to establish the relationship between the mineralogical composition of calculi and impaired excretion of inhibitors and promoters of stone formation.
Materials And Methods: Fifty patients with calcium oxalate urolithiasis were tested using a complex of physicochemical methods. Patients assessment included evaluation of quantitative mineralogical composition of calculi, daily urine pH profile and daily urinary excretion of urates, calcium, magnesium, oxalate, phosphate and citrate ions.
Background: Renal artery denervation (RDN) has provided incremental atrial fibrillation (AF) suppression after pulmonary vein isolation (PVI) in patients with AF in the setting of drug-resistant hypertension.
Objective: To assess the relationship between changes of mean blood pressure (BP) and AF recurrences/AF burden after PVI combined with RDN.
Methods: All patients from two randomized studies with symptomatic paroxysmal AF and/or persistent AF and resistant hypertension who underwent PVI-only (n=37) or PVI with RDN (n=39), and implantable cardiac monitor (ICM) implantation were eligible for this study.
Objective: To conduct a complex examination of female patients with calcium oxalate urolithiasis to detect metabolic disorders, leading to stone formation.
Materials And Methods: The study was carried out using complex physical and chemical methods, including quantitative X-ray phase analysis of urinary stones, pH measurement, volumetry, urine and blood spectrophotometry.
Results: Quantitative mineralogical composition of stones, daily urine pH profile, daily urinary excretion of ions of calcium, magnesium, oxalate, phosphate, citrate and uric acid were determined in 20 female patients with calcium oxalate stones.
This paper focuses on developing and implementing a method of quantitative mineralogical analysis of urinary stones based on powder diffraction data analysis using 4 Topas (Bruker) software. Mineralogical composition of 100 urinary stones from urolithiasis patients living in Ivanovo region was examined. More than 70% of stones consisted of calcium oxalate monohydrate (COM) and calcium oxalate dihydrate (COD), and their mixtures with hydroxylapatite.

Data on the "real incidence" of post-MI arrhythmias are limited. We aimed to determine the rate and burden of cardiac arrhythmias by the use of insertable cardiac monitors (ICM) in patients with preserved left ventricular ejection fraction (LVEF) after AMI.

Material And Methods: We studied the results of examination and treatment of 87 patients with different hepatopancreatobiliary pathology complicated by obstructive jaundice. It was determined blood concentration and range of volatile fatty acids which are metabolites of facultative anaerobic and obligate anaerobic bacterial pathogens.
Background: Catheter ablation is less successful for treatment of persistent atrial fibrillation (PersAF) than for paroxysmal atrial fibrillation. Some studies suggest that left atrial appendage (LAA) isolation in addition to pulmonary vein isolation (PVI) is required to maximize the benefits for PersAF after ablation.
Objective: The purpose of this study was to compare the efficacy and safety of 2 surgical ablation approaches for PersAF via video-assisted thoracoscopy: PVI + box lesion and PVI + box lesion + LAA excision.
The paper presents the results of the 1-year screening of biochemical parameters of urine in female patient with recurrent calcium urate urolithiasis. Based on the data of quantitative X-ray phase analysis of the composition of stone and a complex of clinical and laboratory examination, reasons for recurrent stone formation were determined. The main reasons included hypocitraturia, hyperosmolarity of urine and uric acid diathesis.

Administration of longidaza at a dose of 3000 IU intramuscularly twice a week after 1 month of treatment leads to the statistically significant reduction of antisperm antibodies (ASAB) at the surface of sperm cells to 23% (7-48%) for MARIgG and to 14.5% (3-34%) for MARIgA. Maximum reduction of ASAB, however, was observed after third month of treatment, mean MARIgG was 2% (1-26,5%) and MARIgA - 1% (0-11.

The objective of the present study was the dynamic estimation of the intensity of pain syndrome with the use of a visual-analog scale (VAS), characteristics of the psychological status and cognitive disorders, quality of life, and brain electrogenesis in 50 patients presenting with vertebrogenic pain syndrome of lumbar-sacral localization. It was shown that long-standing pain syndrome plays the dysadaptive role, causes structural and functional changes in the central nervous system (CNS), and is responsible for psychoemotional and cognitive disorders. The introduction of transcranial stimulation in the combined treatment of such patients promotes correction and reversibility of the above disorders, enhances the efficacy of electrotherapy, and improves the quality of life in the subjects with vertebrogenic pain syndrome.

The stone treatment with 5% disodium ethylenediaminetetraacetate aqueous solutions or citrate buffer are found not to provide notable disruption of the samples studied. The significant improvement is reached with the mixed compositions containing both natural and synthetic chelating reagents:citrate and ethylenediaminetetraacetate ions as well as an antibiotic.

ESC and ACC/AHA experts propose to use brain natriuretic peptide (BNP) and/or N-terminal BNP propeptide (NT-proBNP) levels in combination with tissue velocity imaging (TVI) to facilitate diagnostics of this condition. BNP and NT-proBNP levels are highly specific and sensitive indicators of left ventricular myocardium overload while TVI reveals chronic cardiac insufficiency in the asymptomatic phase of its development.
