The article analyzes the use of digital methods and artificial intelligence capabilities for diagnostics in the field of obstetrics and gynecology. The author notes that digital methods and artificial intelligence (AI) have a high potential for the diagnosis of gynecological diseases, since it can analyze medical images and other medical data with great accuracy and speed. For example, AI can help in the diagnosis of cervical cancer by identifying anomalies in digital images and screening tests. The use of AI can also help in the recognition of other gynecological diseases, such as endometriosis, uterine fibroids, polyps, etc. In addition, AI can help improve the efficiency and accuracy of diagnostics, as well as reduce the time required to process medical data. This can be especially important in cases where diagnosis needs to be done quickly in order to start treatment as early as possible. However, it should be noted that AI cannot completely replace the experience and expertise of doctors. Still, it can help doctors make more accurate diagnoses and develop more effective treatment strategies.

The precocious knowledge on reckoning schemes scientifically and technically was replaced with the rapid amelioration in medicinal contrivance systems and treatment information registers. On average the management accomplishes hospital information system (HIS) and picture archiving and communication systems (PACS) using digital entities to maintain medical examinations, images and statements. Such systems even though are much helpful for the hospital staff, doctor away from the hospital have lot of difficulty to access the patient data during risk facing situations. To iron out the above-mentioned complications, a new idea of the proposed framework has been disseminated for medical descriptions to the doctors at inaccessible areas. This organization requires a hand-hand PDA’s that adopts CDMA techniques with mobile networks. This arrangement requires a server and PDA for its implementation. This model supports the entire reports of the patient to the doctors located even at remote location with accessibility and doctor information reliable for patients. PDA created will disclose the inmate’s medicinal reports and scans over an outlying network. To corroborate or validate user data, remote data approach is applied by PDA that connects the server directory and for relegation of information from the server, uses file transfer protocol. From testing, observations show ninety seconds to convey thirty images with a fineness of 832 x 488, intensity of 24 bits and magnitude of 0.37 Mb. This idea proposed using bitmap image acquiring technique demonstrates no difficulty for distant doctors to collect and examine the sufferer images right away at the time of crisis or urgencies, which is completely subjective analysis based on doctor’s point of view.

The absence of neoangiogenesis in the ischemic myocardium is the reason for the widespread prevalence of cardiovascular diseases. The mechanism is the age-dependent epigenetic blockade of the corresponding genes. In model experiments, it was shown that transfection of ischemic myocardium with plasmid vectors carrying the HIF1a, HIF1b, VEGF165, VEGF225 genes in a stoichiometric ratio of 1: 0.2: 0.5: 0.3, at a concentration of 400 μg / ml of physiological solution at a rate of 200 μg DNA per cm2 of ischemia zone and a step over an area of 2-10 mm, with the addition of an adjuvant2-dimethylaminoethanol at a concentration of 2.5 mmol / L, restores full neoangiogenesis. For the first time, it was shown that as a result of gene therapy of myocardial ischemia using four genes (HIF-1α, HIF-1β, VEGF 225, VEGF 165).In contrast to the known monotherapy methods, a complete vascular network is formed in the ischemic zone, having anatamoses with intact vessels. The scientific novelty of the study lies in the fact that the obtained data open the possibility of correction of epigenetic blocking of gene expression by transfecting cells with copies of these genes without epigenetic labels.

Assessment of system-related hemodynamics and tissue hydration in female patients with preeclampsia
Статья научная
Hypertension disorders are reported to cover up to 10% of pregnancies in the world. It is precisely the arterial hypertension that is the leading cause of developing serious complications, long-term invalidation and high maternal and infant mortality rates. In the context of the maternal mortality, preeclampsia may be attributed to 25% of all lethal outcomes. Preeclampsia occupies the second place in the maternal mortality structure. Multifetal pregnancy is a risk factor for developing of preeclampsia. The given study has been designed to obtain main data measured in pregnant patients experiencing preeclampsia. The obtained data have been compared with parameters showing changes in intra-abdominal pressure (IAP) and biochemistry data in singleton versus multifetal pregnancies. Our study has shown that arterial hypertension in multifetal pregnancies may develop due to some factors not typical of preeclampsia pathogenesis. As a result, we may assume that establishing diagnosis Preeclampsia on the basis of arterial hypertention alone may involve an inaccuracy. Therefore, in making the proper diagnostics to differentiate between preeclampsia and other causes of arterial hypertension, it is reasonable to use some additional examination techniques like an impedance measuring method. The hemodynamic data collected therewith can be effectively used in selection of the most suitable hypotensive therapy and adjustment of infusion therapy.

Behavioral shift of generation X towards OTT during COVID’19 in India
Статья научная
Over-the-top (OTT) services such as Netflix, Prime Video, Disney+ Hotstar, Zee5, etc., have changed consumers’ content consumption behavior. Globalization and Digitalization have encouraged consumers to have limitless access to the Internet for information, leisure, entertainment, and social interconnectedness. The increase in the availability of high-speed Internet, the latest smartphones, and breakthroughs in technology have created great opportunities for the OTT sector, with people preferring to consume content on-the-go digitally rather than traditional media services, such as cable television. The Covid’19 pandemic has seen an increase in viewership’s and subscriptions towards these streaming platforms, with people of different age groups adapting to changing viewership trends. This study aims to understand Generation X’s behavioral shift (Age 41 to 55) towards OTT during Covid’19 in India. The literature review talks about the Generation X cohort of consumers, their behavioral habits, and attitudes towards technology. It also discusses the changing trends of online content consumption and how Covid’19 has created a spark in viewership’s towards India’s online media services. The research study aims to perform explanatory research to establish a relationship between the increase in consumption and subscriptions of OTT services in India by Generation X and the impact of Covid’19 on the same. Data will be collected from consumer’s age amongst 41 to 55 in India via survey questionnaires, and linear regression tests will be performed to test the hypotheses and establish a correlation between the dependent and independent variables.

Objective: In this study, copper oxide nanoparticles are produced using the probiotic Saccharomyces boulardii in order to assess their biological activity. The biological method of producing nanoparticles is gaining popularity due to its benefits over chemical and physical ways of synthesis in terms of affordability and environmental friendliness. Methods: To biosynthesize CuO NPs, copper sulfate was introduced at a concentration to S. boulardii’s cellfree supernatant. Results: The color change of the reaction mixture from light to dark after 150 rpm incubation, as well as the color change and antibacterial behavior, were indicators of S. bularedii’s biosynthesis of CuO NPs. The characterization completed by UV-visible spectroscopy, Atomic force microscopy, Energy Dispersive Spectroscopy, Fourier Transform Infrared Spectroscopy, Scanning Electron Microscopy, and X-ray diffraction (AFM). The CuO NP absorption spectra in the reaction mixture’s UV visible spectroscopy were (537.93 nm). The XRD showed that CuO NPs’ crystal size was (14.65 nm). The SEM was provided; the shape was uniform and spherical, and the average size (16.03 nm). EDS was used to analyze the presence of elemental CuO NPs. The CuO NPs’ three-dimensional structure was seen by the AFM, and their average diameter was (41.11 nm). The FTIR spectrum reveals a variety of functional groups that are present at various locations. Gram positive and gram negative bacteria that were isolated from diabetic foot infections were multidrug resistant (MDR), and biosynthesized CuO NPs demonstrated antibacterial action against these bacteria (Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa and Proteus mirabilis). In the form of biofilm using a microtiter plate.

Breast health is extremely important for all women. However, the breast is another region of the human body that is susceptible to cancer. Breast cancer is becoming increasingly common these days, and it is now one of the leading causes of mortality globally. According to the World Health Organization, breast cancer is the most common disease among women worldwide, claiming the lives of hundreds of thousands of women each year and impacting nations at all stages of development. In fact, it is the most common cancer in women, with a significant incidence observed among those aged 30 to 50. The goal of the World Health Organization’s Worldwide Breast Cancer Initiative (GBCI) is to reduce global breast cancer mortality by 2.5 percent each year; As a result, 2.5 million breast cancer deaths will be avoided globally between 2020 and 2040. To achieve these goals, three pillars must be in place: health endorsement for early detection, suitable identification at the right time, and comprehensive breast cancer management. Because of advances in early detection and care, the incidence of women dying of breast cancer has decreased by 41% from 1989 to 2018. During that time, more than 403,000 breast cancer deaths were prevented.

COVID-19 pandemic: impact and opportunities for education in India
Статья научная
The sudden breakout of COVID-19 has created a major crisis in almost every sector like Travel and Tourism, Entertainment, Sports, Corporates, Financials, Manufacturing, Education, and Service sectors. We cannot identify any sector which remained unaffected by the crisis. The magnitude of the impact may vary from sector to sector. The same happened to the Indian education system. It has faced a worldwide lockdown estimating to impact almost 320 million learners across the country. India has a robust education structure, with a huge chain of more than 1.4 million schools, 799 Universities, 39071 Colleges, and 11923 Stand Alone Institutions as per data available on the sixth report of ‘All India Survey on Higher Education on the web portal, are all affected by the pandemic situation. Our Indian education system was badly impacted due to pandemics, mostly based on traditional or classroom teaching. Though most of the school and colleges, for the benefit of students, had opted for online teaching, yet some of the low income private and government teaching institutes and students from a remote location could not opt to online teaching due to the unavailability of the internet, Laptop, Desktop or Smartphones persistent with a survey by EY-Parthenon.

The aim of this research work is to study the cAMP level in the cardiac mitochondria and serum in the C57BL/6 strain mice of both genders under the independent melanoma B16/F10 growth versus the melanoma B16/F10 growth linked to chronic neurogenic pain (CNP). Materials and methods. Mice of strain C57BL/6 (n=336) have been grouped as follows: the intact group of the mice (♂n=21; ♀n=21), the reference group (♂n=21; ♀n=21) with the reproduced CNP model, the comparison group (♂n=63; ♀n=63) to include the mice with melanoma B16/F10, and the main test group (♂n=63; ♀n=63) to cover the mice with the melanoma growth against the CNP background. Upon expiration of 1 week, 2 and 3 weeks of the melanoma growth, in the animals of the above experimental groups the cardiac mitochondria have been isolated with the centrifugation using high-performance refrigerated centrifuge Avanti J-E, BECMAN COULTER, USA. With ELISA Kit (RayBio USA) we have determined cAMP concentrations in serum and in the cardiac mitochondria. Results. CNP has induced a decrease in the cAMP level in the cardiac mitochondria by a factor of 3,6 in the female mice only. In the animals of the comparison group the cAMP level in the heart has been increasing beginning with week 2 of the tumor growth on average by a factor of 4, while in the main test group starting from week 1 of the tumor growth it has been recorded 2-4 times higher and was depleted by the end of the experiment. As to the cAMP concentration in serum, the dynamics thereof has not been found to be in correlation with the cardiac mitochondrial data, and its concentration decrease has been recorded both in the females and the males. Conclusion. So, the changes in the cAMP concentration in the cardiac mitochondria demonstrate their gender-specific feature; the female mice as against the males have responded to an independent impact produced by CNP. As to the main test group, CNP has stimulated an increase in the cAMP level in the cardiac mitochondria 1 week earlier than it is the case with the comparison group, and it has resulted in the full cAMP depletion by the 3rd week of the experiment.

Aims The article presents the results of an experimental study of the cardiometric detection of a person's emotional reactions to verbal, audial and visual stimuli. Materials and methods To test the hypothesis of our study, we carried out a series of experiments in which two groups of stimuli have been used purposefully, one of which had to cause sthenic and the other asthenic reactions in our examinees. In order to activate various types of sensory systems, only stimuli of the audial modality (the A-type stimuli), only visual modality (the V-type stimuli), and also stimuli with a combination of audiovisual modalities (the VА -type stimuli) have been included in each group. In addition, as stimuli, we prepared a list of imaginary situations (the I-type stimuli) to initiate either sthenic or asthenic emotional reactions in the examinees. For the cardiological data recording and subsequent assessment of HRV, we used the Cardiocode PC-assisted hemodynamic analyzer. Portable eyetracker GP-3 has been employed to record the examinees' oculomotor reactions to visual stimuli...

The paper presents our experimental evidence of validity of our hypothesis that definite, substantively different, psychophysiological states of a human individual can be really fixed with the use of metaphoric associative cards, and that transitions from one psychophysiological state to another are accompanied by significant changes in the performance of the human organism, and, first of all, in the performance of the heart. It has been shown that the metaphoric associative cards can serve not only as a good forecasting tool, a sort of predictors of human behavior in certain emotionally charged, stress-provoking, situations, but also as a means for active modeling of optimal mode to adequately overcome these difficulties.

Cardiometric fingerprints of various human ego states
Статья научная
The article presents experimental evidence of the validity of the hypothesis that theoretical construct “ego state”, in addition to the psychological content, actually reflects the physiological mobilization of a human individual to provide a certain type of response. It is shown that the mobilization is manifested in a certain specific pattern inherent to the cardiovascular system performance. Experimental evidence is given herein that the ego-state theoretical construct really captures reasonably definite, content-related different psycho-physiological states of an individual. It is shown that the transitions from one ego state to another are indeed accompanied by significant changes in heart rate variability, which has been estimated using the Baevsky stress index (SI). The article also provides experimental data confirming the validity of using the Baevsky stress index (SI) to assess the effectiveness of the application of the transactional analysis as a psychotherapeutic and psychocorrectional technique.

Cardiometric taxonomy of stress-inducing potential in diverse domestic situations
Статья научная
Aims The aim of our study is to empirically verify the conceptual possibility of constructing a taxonomy of diverse domestic situations, which may become the basis for choosing the best ways to increase an individual stress resistance in a human subject. Materials and methods To achieve the aim, after ranking of the subjective evaluations of the occurrence rate of this sort of situations and the degree of intensity of stress induced by the situational cases, we have prepared a set of their laconic descriptions. As a result, a catalogue of 10 paired tasks has been prepared by us. One of these tasks offers that an examinee should imagine and hold in his/her memory for a certain time an image of a stress-inducing situation case as designated by the examiner. The other examinee in this pair has been instructed to imagine an alternative situation, when anticipated are a high level of the calm, trouble-free state, physical comfort and good emotional balance. During the execution of each task, an ECG and a rheogram of every examinee have been recorded...
