Thermograms show the distribution of thermal fields, corresponding or not corresponding to normal thermography of specific areas. The presence of a pathological thermal picture indicates a certain pathology. Medical thermography makes it possible to conduct an examination in a short time (5-10 minutes) with the construction of accurate heat maps and is a safe method of primary diagnosis. Infrared thermal mapping provides a study of the development of a thermoactive process in time, which increases the diagnostic capabilities of the method, especially in the early stages of disease development. The aim of this work is to study the possibilities of medical thermography in the treatment of malignant meningioma by the method of alfitherapy. Alphitherapy (algo – algae, phyto– plants) is a direction in medicine, veterinary medicine, cosmetology, which is distinguished by the fact that it allows you to completely restore the entire body and get rid of hormonal, chronic, acute and concomitant diseases due to a proper balanced diet, which consists of algae, plants, macro- and microelements, vitamins with the presence of plant microorganisms. The data obtained as a result of many years of research indicate that alpha drugs contain a rich set of biologically active substances with versatile pharmacological activity, which are successfully used to treat a wide range of cardiovascular and oncological diseases, injuries and other health disorders. The results of application of the method of medical thermography in alfitherapy based on the portable thermograph IRTIS-2000 ME are presented. A patient was considered whose results of thermographic examination revealed malignant meningioma (brain cancer). As a result of the use of the alfitherapy method, the malignant meningioma was completely cured without surgery. A description of the biological mechanisms of alfitherapy and alfitherapeutic action for the treatment of cardiovascular and oncological diseases is given. The areas of application of medical thermography in medical diagnostics are presented. It has been shown that the use of medical thermography allows non-invasive primary diagnostics and monitoring of the state of human health, and alfitherapy allows effective non-surgical restoration of the whole organism, regardless of nosology.","PeriodicalId":169108,"journal":{"name":"Biomedical Radioelectronics","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130551638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the common pain stimuli used in many laboratories in the world is electric current. In behavioral experiments, a common way of organizing an electrical impact on a moving laboratory animal is to apply electrical voltage to the metal bars of the experimental cage floor. When the animal locks bars with different potential, it receives an electrical shock. It is desirable during the experiment to change the polarity of the electric potential on the bars of the lattice, in order to minimize the ability of the animal to avoid electrical exposure, located on the bars with the same electric potential. The sequence of polarity reversal on metal bars of the cage floor was organized in such a way that not a single pair of bars had the same polarity during the supply cycles of electric current pulses and the animal received an electrical shock at least once per cycle when it closed any pair of bars. Experimental techniques are known in which the voltage applied to the cage floor between adjacent conductive bars is manually controlled by means of a transformer with control of the voltage value on the voltmeter. In this case, the determination of the threshold of pain sensitivity occurs with an error due to a large, manually adjustable pitch of change in electrical voltage. In a number of experiments, it is desirable to provide a more accurate setting of the minimum values of the voltage level and the registration of the current value characterizing the minimum pain sensitivity threshold, as well as to ensure accurate repeatability of the steps of voltage level variation in different experiments with different animals. In order to exclude the possibility for animals to find equipotential bars of the cage floor to avoid electrical shock, for example, they apply electric stimulation independently to each conductive bar of the cage floor, providing a multiphase pulse repetition mode. For accurate and effective determination of the pain threshold of laboratory animals, the device MD280 was developed and implemented. Each electronic key in the device is connected to a specific register bit, and each bar of the cage floor is connected via an electronic key to a controlled constant-voltage source. In turn, the register and voltage source are connected to a control unit connected to the computer via a USB controller. In addition, the device provides correct information by eliminating the possibility of an animal avoiding electrical impact by implementing control of the pulse feed sequence with adjustable phasing (set by the time shift of the pulses on the conductive bars of the floor) and by fixing and saving the measurement sequence at each step of changing the parameters. Interaction with the device is carried out using a computer with USB 2.0 Full-Speed. Data exchange with the PC via the USB interface is performed by a USB-FIFO converter implemented on an FT245RL (FTDI) chip and a","PeriodicalId":169108,"journal":{"name":"Biomedical Radioelectronics","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124907067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Identification and classification of the body's typical reactions to specific changes in environmental conditions, primarily related to the performance of activities within the framework of extreme professions, remain the actual problem. The objective of the study was to identify changes in the state of the main indicators of the cardiovascular system – blood pressure (BP), heart rate (HR) and respiratory rate (RR) – in individuals with different background values of these indicators when exposed to conditions of high-altitude hypoxia. After the study of 43 healthy male volunteers aged 30–35 (conducted according to the original method of raising the subjects in the pressure chamber to a height of 5000 m) it was found the subjects showed different \"patterns\" of changes in BP, RR and HR, depending on the background values. BP increased in proportion to its background values. The change in RR had a complex dynamics. And the HR increased to approximately the same values in individuals with different values of background indicators. The revealed patterns of changes in BP, RR and HR should be taken into account when selecting individuals for activities associated with being in conditions of high-altitude hypoxia. The patterns will also make it possible to optimize the work and rest time of persons already engaged in such activities, depending on the physiological characteristics of their body.","PeriodicalId":169108,"journal":{"name":"Biomedical Radioelectronics","volume":"500 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123069600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In last few years, several researches revealed rhythmic character of processes of attention. Especially theta-rhythm is considered to be significant in organization of rhythmic interactions between brain zones, which take part in providing attention systems work. The aim of the work – to analyze and summarize modern date about role of theta-rhythm in providing basic processes of attention. The report presents modern data about role of theta-rhythm in processes of attention. Specific features of attention systems are discussed. Thrifold model of attention, developed by Steven E. Petersen and Michael I. Posner is reviewed in detail. Moreover, evidences of rhythmic character of processes of attention are summarized and leading part of theta-activity in providing these processes is demonstrated. We also discuss the investigations by Randolph F. Helfrich and Ian C. Fiebelkorn et al. which stated that the quantization of processes of attention with theta-frequency as a general principle of brain structures activity. Dependence of frequency characteristics of cortex zones of human brain from number of objects of attention is discussed. There is also an analysis of theta-band’s ability to modulate biopotentials of higher frequency. Special attention is paid to the researches focused on theta-gamma coupling. The influence of theta-rhythm phase on gamma-rhythm amplitude in phase-amplitude coupling of theta- and gamma-band is analyzed. Theta-rhythm is considered to be one of the rhythmic components that regulate complex mental functions such as attention, memory and consciousness. Obviously, there is a lack of an exact understanding of the role for every band in mental functions regulation; therefore, more investigations in this field are required. However, several data about the role of theta-band in mental functions was collected. A complex of systems with different physiological and neurochemical basis provides attention. It was demonstrated that attention - is a rhythmical process in which theta-band is a crucial part. Theta-rhythm provides synchronization and joint activity of distant brain structures. Moreover, theta-rhythm modulates high-frequent bands. Theta- gamma-band coupling is supposed to be important for attention. Such cooperation is considered to be an evidence of cortical and subcortical zones and provides coordination of analyzing systems of different level. It is suggested that different phases of theta-band may provide retention/switching of attention or determine information flow. As a summary of review of literary sources, there is a conclusion about high significance of this frequency range in different attention systems functioning.","PeriodicalId":169108,"journal":{"name":"Biomedical Radioelectronics","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125400761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
