Possible relations between arterial hypertension and cervical spine fibromyalgias (literature review)

The literature review analyses and systematises currently available information on fibromyalgia etiology and pathogenesis, hypertension classification and causes, and considers possible relationships between cervical fibromyalgia and hypertension. Statistical data on mortality in Ukraine related to cardiovascular diseases, including hypertension, are highlighted. A concise classification of arterial hypertension according to the International Classification of Diseases-10 (ICD-10) and the International Classification of Diseases-11 (ICD-11) is provided, and its pathogenesis (emission hypertension, resistance hypertension and hypervolemia) is outlined. Physiological relations between cervical spine and cardiovascular system are considered. The main diagnostic criteria for fibromyalgia classification and its development stages are described. Prevalence of fibromyalgia is identified and its forms are classified in accordance with ICD-11. The available data on the likely causes of fibromyalgia pain and any established mechanisms of fibromyalgia pathogenesis, including, but not limited to peripheral and central sensitisation, neurogenic inflammatory processes occurring in the disease-associated peripheral tissues, spinal cord and brain, as well as potential involvement of genetic, endocrine, psychopathological factors and sleep disorders in fibromyalgia development are discussed. The current formal criteria for fibromyalgia classification (revised in 2016), together with assessment of the main pharmacological and non-pharmacological fibromyalgia treatment methods and approaches based upon available published clinical trials outcomes are described. The main directions of fibromyalgia research are identified, and further prospective studies covering different relationship aspects between hypertension and cervical fibromyalgia are evaluated. Among the available literature sources, the only study of patients with comorbid fibromyalgia (fibromyalgia was diagnosed using 1990 American College of Rheumatology criteria and evaluated by Revised fibromyalgia impact questionnaire (FIQR)) and hypertension (blood pressure levels were assessed using the WHO protocol) has been reported. However, this group has only studied the dynamics of changes in cortisol, melatonin and serotonin blood levels, which accompany these pathologies, and these authors have found that fibromyalgia tender points’ quantity and FIQR scores are much higher in hypertensive patients with fibromyalgia in comparison with the rest, which has led them to the conclusion that hypertension prevalence in patients with fibromyalgia could be related to fibromyalgia severity. Thus, this thorough literature review demonstrates that clinical studies examining possible relationships between hypertension and cervical spine fibromyalgia are at lack and require further considerations

Coordination of Cu(II) and Ni(II) in polymers imprinted so as to optimize amine chelate formation

Molecular imprinting has become an established technique. However, little was done on direct investigation of the sorbents produced. In the present work, en ESR method was used for the investigation of the complex formation processes within the sorbents imprinted with copper(II) and nickel(II). The sorbents were synthesized from a mixture of linear low molecular weight polyethyleneimine oligomers. The composition, structure and distribution of complexes in the resin phase were investigated. The effects of the synthesis conditions, loading degree and water content were examined. The presence of certain copper complexes was found to be a convenient characteristic of the imprinting efficiency. The optimum synthesis conditions for obtaining sorbents imprinted with copper(II) or nickel(II) were identified. The imprinting results in the improvement of the stability of the complexes and the selectivity and working capacity of the sorbents. The imprinted samples are also characterized by a more even distribution of chelating sites. The synthesis conditions and loading by ions allow for the regulation of the ratio between individual complexes and magnetic associates in the resin phase. This is a critical point on the future use of the metal containing imprinted sorbents as catalysts. (C) 2003 Published by Elsevier Science Ltd

On a nonlocal problem in function theory

We consider nonlocal boundary value problems for three harmonic functions each of which is defined in its own domain. A contact condition is posed on the common part of the boundaries of these domains, and the Dirichlet or Neumann data (or mixed boundary conditions) are given on the remaining parts of the boundary. We prove the unique solvability of these problemsyesBelgorod State Universit

Peculiarities of Construction of Visual Range (Photo-Report) in Modern Electronic Media on the Example of Chelyabinsk Region

A huge flow of information hits the modern man. Electronic media should take into account the current situation. In addition, with the development of technologies, the type of thinking of a person has changed to the prevalence of cogency. To keep the reader on your page you need to fill the site with quality content. That is when the visualization of news comes to the fore. While creating a news line, each electronic media tries to illustrate the news with photo-images. The role of photo essays in modern electronic media has increased tremendously.Огромный поток информации обрушивается на современного человека. Электронные СМИ должны учитывать сложившуюся ситуацию. Кроме того, с развитием технологий изменился тип мышления человека. Преобладает клиповость мышления. Для удержания читателя на своей странице требуется наполнять сайт качественным контентом. Визуализация новостей выходит на передний план. При формировании ленты новостей каждое электронное СМИ старается иллюстрировать новость фотоизображениями. Роль фоторепортажа в современных электронных СМИ чрезвычайно повысилась
