Optical techniques are utilized for the non-invasive analysis of zebrafish cardiovascular system at early developmental stages. Being based mainly on conventional optical microscopy components and image sensors, wavelength range collected analyzed light is not out scope 400-900 nm. In this paper, we compared approaches utilizing visible near infrared (VISNIR) 400-1000 shortwave (SWIR) 900-1700 The transmittance spectra tissues were measured in these ranges, then vessel maps, heart rates,...
Identification of specific vascular patterns in skin formations is important for non-invasive differential diagnosis benign and malignant tissues. Accurate blood vessel mapping quantitative analysis the vessels morphology may increase diagnostic efficiency significantly comparison to conventional dermatoscopy methods. In this paper, we propose videocapillaroscopy technique visualization microvascular architecture right nevi area. It includes acquisition lesion images by exoscope-based...
Subject of study. The investigation pertains to the optical systems medical devices designed for dermatoscopy and capillaroscopy, with a focus on facilitating non-invasive skin microcirculation diagnostics. aim study is design an system that integrates visual observation capabilities dermatoscope essential features modern video capillaroscope, namely, capillary blood flow imaging photoplethysmography. Photoplethysmography recording changes in amplitude volume fluctuations occur during...
Dermographism urticaria, which affects up to 5% of the general population, is defined by intensive reaction mechanic impact on skin expressed in wheals and heavily decreases quality patient life. The diagnosis dermographism based a provocative test, subjective qualitative, highly dependent expertise medical staff. At same time, it has been well established that capillaries are first structures react external stimuli. To estimate this response quantitatively, we propose analyzing changes...
Toxic environmental pollutants pose a health risk for both humans and animals. Accumulation of industrial contaminants in freshwater fish may become significant threat to biodiversity. Comprehensive monitoring the impact stressors on functional systems is important use non-invasive tools that can detect presence these toxicants vivo desirable. The blood circulatory system, by virtue its sensitivity external stimuli, could be an informative indicator chemical exposure. In this study,...
Capillaries immediately respond to various physical stimuli and environmental stressors. Accurate monitoring the capillary network activity enables timely diagnosis of dermatological, cardiovascular other diseases. In this study, we present a software application for processing skin images, tracking individual capillaries, vessel morphology hemodynamics measurements. We describe key features app demonstrate its efficiency visualization quantification net-works.
Zebrafish has become a popular and highly effective animal model for human disease studies biomedical discovery. Though multiple techniques have been developed testing its resistance to environmental, toxicological other stressors. For in vivo of the side effects toxicants on particular organs, non-invasive imaging are necessary. example, optical tracking variations transmitted light intensity allows accurate blood vessel mapping whole while monitoring polarization state muscles imaging. In...
Chronic tonsillitis is a common disease caused by bacterial or viral infections. The most significant complication of tonsillectomy indicated in patients with chronic postoperative bleeding. For its prevention, accurate control wound healing oral cavity mandatory. Microcirculation the soft palate and tonsils may provide valuable information on this due to neoangiogenesis that accompanies mucosa restoration. In study, we propose an optical technique for non-invasive monitoring...
Zebrafish is a popular model organism for human diseases research, drug testing and other biomedical study tasks. Cardiovascular muscular system parameters are valuable indicators of disorders its response to stress. Noninvasive productive methods assessing zebrafish body state rapidly evolving. In this study, we present an image processing algorithm software application such method that enables simultaneous imaging quantification the cardiovascular systems optically transparent biological...
Background: Cold urticaria (ColdU) is a common type of chronic inducible urticaria. Patients with typical ColdU develop wheals in response to standard cold stimulation tests (CSTs), an ice cube (ICT) or TempTest . As now, the evaluation CST visual and subjective. Validated, robust, objective test readouts lacking today are needed. Methods: We subjected 63 patients (39 24 atypical ColdU) 15 healthy controls (HCs) CSTs critical temperature threshold assessments. Blood microcirculation...
Avena sativa L. is valuable vital cereal and sustainable protein source. The impurity fatua makes a great contribution to the decrease in quality of grain. Traditional methods for detecting quantifying impurities are laborious do not provide sufficient speed accuracy. In this regard, imaging spectroscopy becoming increasingly popular, including because ability simultaneously analyse morphological spectral features mixture grains. paper, we investigate feasibility an method analysis grains...
