Cryosurgery for Basal Cell Skin Cancer of the Head: 15 Years of Experience.

The clinical relevance of head and neck (H&N) tumors is related to the potential disfiguration of anatomical structures (by the tumor or surgical intervention), defining patients' individual features and emotional expression, loss or restraint of vital structures functions, and untoward socio-economic sequelae. This study is aimed to improve clinical outcomes of cryosurgery in patients with H&N basal cell skin cancer by refining the indications for cryosurgical treatment. In this study, cryosurgery was used in 234 patients with different stages of cutaneous basal cell carcinoma (BCC) of the head, including 101 patients with T1 tumors, 86-with T2, 5-T3, and 42 patients with tumors relapsing after failure of preceding various treatment modalities.

[Multiple sclerosis and melanoma].

Multiple sclerosis (MS) is a chronic autoimmune progressive demyelinating disease of the central nervous system, mainly in young people. The clinical picture of MS has a variety of neurological symptoms, which manifests itself during periods of exacerbation or progression and stabilizes at the moments of remission. The widespread introduction of new drugs with immunosuppressive and immunomodulatory mechanisms of action has led to the development of special risk management plans for monitoring patients during therapy and preventing adverse events and new comorbid conditions.

Fluorescence lifetime-based assay reports structural changes in cardiac muscle mediated by effectors of contractile regulation.

Cardiac muscle contraction is regulated by Ca2+-induced structural changes of the thin filaments to permit myosin cross-bridge cycling driven by ATP hydrolysis in the sarcomere. In congestive heart failure, contraction is weakened, and thus targeting the contractile proteins of the sarcomere is a promising approach to therapy. However, development of novel therapeutic interventions has been challenging due to a lack of precise discovery tools.

[The problem of chronic tonsillitis as a priority area of scientific research of the Department of Otorhinolaryngology named after acad. B.S. Preobrazhensky].

The article summarizes data on many years of versatile research on the problem of chronic tonsillitis, which were conducted at the Department of Otorhinolaryngology named after acad. B.S.

Wound healing activity of aqueous dispersion of fullerene C produced by "green technology".

In addition to exhibited antioxidant and anti-inflammatory activity, fullerene C60 is a promising wound healing agent. An important stage in the production of fullerene-based ointments is the stability of the aqueous fullerene dispersion (AFD) with minimum size of colloidal fullerene aggregates and sufficiently high concentration. To achieve these parameters tangential flow filtration of fullerene C60 was used ("green technology").

[Chest pain and chronic heart failure as a manifestation of tertiary syphilis: clinical case].

In cardiological practice, there may be patients with chest pain and heart failure of a specific etiology, including an association with cardiovascular syphilis. This article describes a 49-year patient with chest pain, heart failure, and neurological symptoms associated with ongoing tertiary syphilis. The history included an antisyphilitic treatment 30 years before the current hospitalization.

Method of transmission filters to measure emission spectra in strongly scattering media.

We describe a method based on a pair of transmission filters placed in the emission path of a microscope to resolve the emission wavelength of every point in an image. The method can be applied to any type of imaging device that provides the light in the wavelength transmission range of the filters. Unique characteristics of the filter approach are that the light does not need to be collimated and the wavelength response does not depend on the scattering of the sample or tissue.

Present and future projections of heatwave hazard-risk over India: A regional earth system model assessment.

The heatwave is a disastrous hazard having significant impacts on health and society. This study analyses the heatwave hazards and risk for India's current and future scenarios using socioeconomic vulnerability and temperature datasets during the summer (April-June) season. The Census of India (CoI) 2011 datasets were considered to assess current vulnerability and projected from the SocioEconomic Data And Application Center (SEDAC) population at Shared Socioeconomic Pathway (SSP) 4 for future vulnerability.

TFEB Overexpression, Not mTOR Inhibition, Ameliorates RagC Cardiomyopathy.

A de novo missense variant in Rag GTPase protein C (RagC) was recently identified in a syndromic dilated cardiomyopathy (DCM) patient. However, its pathogenicity and the related therapeutic strategy remain unclear. We generated a zebrafish Rragc (corresponding to human RagC) knock-in (KI) line via TALEN technology.

Rivaroxaban for the prevention of venous thromboembolism after radiofrequency ablation of saphenous veins concomitant with miniphlebectomy, sclerotherapy, or no treatment of varicose tributaries.

Objective: To assess the efficacy and safety of once-daily 10 mg rivaroxaban for venous thromboembolism prophylaxis after ClosureFast radiofrequency ablation (RFA) of saphenous veins.

Method: The medical records of patients, who had a Caprini score of ≥3, underwent RFA, received prophylactic rivaroxaban for five days, and completed follow up at one month were reviewed for efficacy (a combination of endovenous heat-induced thrombosis [EHIT] grade of 2-4, any symptomatic or asymptomatic deep vein thrombosis [DVT], and symptomatic pulmonary embolism [PE]) and safety (a combination of major and clinically relevant non-major [CRNM] bleeding) outcomes.

Results: The results of RFA for 248 great saphenous and 24 small saphenous veins with the concomitant miniphlebectomy (63.

[Study of certain electrophysical properties of adipose tissue in the postmortem period when working with a direct current source].

Unlabelled: Some features of changes in the electrophysical properties of adipose tissue of animal origin in the postmortem period when working with direct-current sources are considered.

Objective: Evaluate experimentally the possibilities of registering changes in the electro-physical properties of biological tissues using a direct current source when working with a specific resistance as well as to identify the possible recorded changes in biological tissues when a reverse electromotive force and polarization phenomena occur. At the first stage the fatty subcutaneous layer of a pig was used as samples of adipose tissue which is closely similar to human adipose tissue in composition.

Cutaneomeningospinal Angiomatosis (Cobb Syndrome) in a Young Patient.

Cobb Syndrome (Spinal Arteriovenous Metameric Syndrome 1-31 (SAMS 1-31)) is a rare, non-hereditary disorder. Approximately 100 cases of CS have been described to date. The actual incidence may be much higher since only symptomatic patients were documented.

Blind Resolution of Lifetime Components in Individual Pixels of Fluorescence Lifetime Images Using the Phasor Approach.

The phasor approach is used in fluorescence lifetime imaging microscopy for several purposes, notably to calculate the metabolic index of single cells and tissues. An important feature of the phasor approach is that it is a fit-free method allowing immediate and easy to interpret analysis of images. In a recent paper, we showed that three or four intensity fractions of exponential components can be resolved in each pixel of an image by the phasor approach using simple algebra, provided the component phasors are known.

Respiratory syncytial virus upregulates IL-33 expression in mouse model of virus-induced inflammation exacerbation in OVA-sensitized mice and in asthmatic subjects.

Background: Bronchial asthma (BA) is a chronic disease of the airways. The great majority of BA exacerbations are associated with respiratory viral infections. Recent findings point out a possible role of proinflammatory cytokine interleukin-33 (IL-33) in the development of atopic diseases.

Phasor approach to autofluorescence lifetime imaging FLIM can be a quantitative biomarker of chronic renal parenchymal injury.

Diabetic kidney disease continues to be the leading cause of chronic kidney disease, often advancing to end stage kidney disease. In addition to the well characterized glomerular alterations including mesangial expansion, podocyte injury, and glomerulosclerosis, tubulointerstitial fibrosis is also an important component of diabetic kidney injury. Similarly, tubulointerstitial fibrosis is a critical component of any chronic kidney injury.

M1-like macrophages are potent producers of anti-viral interferons and M1-associated marker-positive lung macrophages are decreased during rhinovirus-induced asthma exacerbations.

Background: Macrophages (Mф) can be M1/M2 polarized by Th1/2 signals, respectively. M2-like Mф are thought to be important in asthma pathogenesis, and M1-like in anti-infective immunity, however their roles in virus-induced asthma exacerbations are unknown. Our objectives were (i) to assess polarised Mф phenotype responses to rhinovirus (RV) infection in vitro and (ii) to assess Mф phenotypes in healthy subjects and people with asthma before and during experimental RV infection in vivo.

Bile acid sequestration reverses liver injury and prevents progression of nonalcoholic steatohepatitis in Western diet-fed mice.

Nonalcoholic fatty liver disease is a rapidly rising problem in the 21st century and is a leading cause of chronic liver disease that can lead to end-stage liver diseases, including cirrhosis and hepatocellular cancer. Despite this rising epidemic, no pharmacological treatment has yet been established to treat this disease. The rapidly increasing prevalence of nonalcoholic fatty liver disease and its aggressive form, nonalcoholic steatohepatitis (NASH), requires novel therapeutic approaches to prevent disease progression.

Retinoid X receptor alpha is a spatiotemporally predominant therapeutic target for anthracycline-induced cardiotoxicity.

To uncover the genetic basis of anthracycline-induced cardiotoxicity (AIC), we recently established a genetic suppressor screening strategy in zebrafish. Here, we report the molecular and cellular nature of , a salutary modifier mutant that affects . We showed that endothelial, but not myocardial or epicardial, activation confers AIC protection.

Ultrashort ssDNA in Retinoblastoma Patients Blood Plasma Detected by a Novel High Resolution HPLC Technique: a Preliminary Report.

A significant population of ultrashort (50-150n) single-stranded DNA fragments were found in exosome-free blood plasma of retinoblastoma patients (6.84 ng mL-1), but not in plasma of healthy donors. An original high resolution HPLC technique has been proposed to reveal and characterize this peculiarity.

The frequency and clinical significance of nontarget superficial and deep vein occlusion after physician compounded foam sclerotherapy of varicose tributaries.

Objective: To evaluate the incidence and clinical relevance of silent nontarget occlusion (NTO) of superficial and deep veins occurring after ultrasound-guided foam sclerotherapy (UGFS) that can be detected by serial duplex ultrasound scan (DUS).

Methods: This retrospective analysis evaluated the medical records of patients treated with UGFS at a private clinic in Moscow, Russia from 2015 to 2017. All patients underwent serial DUS at 1 to 2 weeks and 1, 3, 6, and 12 months after UGFS.

Multicomponent Analysis of Phasor Plot in a Single Pixel to Calculate Changes of Metabolic Trajectory in Biological Systems.

Phasor FLIM in cells undergoing oxidative stress and in mice liver sections have shown the presence of a third autofluorescent component indicative of lipid droplets along with free and enzyme-bound NADH with similar emissions. This third component affects the position and shape of the phasor distribution, pushing it away from the metabolic trajectory. Phasor rule of addition is still valid and was exploited here to create a multicomponent analysis where the phasor distribution can be reassigned to the metabolic trajectory and changes in metabolism can be detected independently of the intensity of this third component.

Haploinsufficiency of mechanistic target of rapamycin ameliorates cardiomyopathy in adult zebrafish.

The adult zebrafish is an emerging vertebrate model for studying human cardiomyopathies; however, whether the simple zebrafish heart can model different subtypes of cardiomyopathies, such as dilated cardiomyopathy (DCM), remains elusive. Here, we generated and characterized an inherited DCM model in adult zebrafish and used this model to search for therapeutic strategies. We employed transcription activator-like effector nuclease (TALEN) genome editing technology to generate frame-shift mutants for the zebrafish ortholog of human BCL2-associated athanogene 3 (), an established DCM-causative gene.

Association between Disturbances in Polyunsaturated Fatty Acid Metabolism and Development of Oxidative Stress during Experimental Diabetes Mellitus.

We studied the effect of streptozotocin-induced diabetes mellitus on the level of glycemia and some other indices of lipid metabolism, including fatty acid metabolism and LPO intensity, during the development of diabetes mellitus in rats. Even at the early terms of diabetes development, hypertriglyceridemia and hypercholesterolemia were accompanied by changes in the blood content of fatty acid (at the expense of ω3 and ω6 fatty acids) that persisted throughout the observation period. Intensification of LPO against the background of suppressed activity of antioxidant enzymes and reduced level of ω3 fatty acids attested to the development of oxidative stress.
