Abstract This paper studies the “human circulatory statues” which Salomon Reisel designed in the 1670s in order to demonstrate the circulation of the blood and its effect on the brain. It investigates how Reisel intended this project to promote Descartes’ philosophy, and how it relates to contemporary diagrammatic schematizations of the blood circulation system. It further explores Reisel’s claims concerning the epistemological and practical advantages of working with a three-dimensional model and argues that Reisel intended his statua to address the concerns of his fellow physicians and, more specifically, to help in diagnostics. I consider the background, strategy and legacy of the essays in which Reisel presented his devices, as well as their relevance to the general project of the scien­tific journal – one of the earliest – in which they appeared, the Miscellanea Curiosa. Reisel was a leading physician who acted throughout his life as a mediator between the Royal Society and the Academia Naturæ Curiosorum. His articles, the paper argues, have much to tell us much about the role played by the recently established scientific academies and their journals in shaping the transmission of early modern science and medicine, in terms both of theories and of the knowledge embodied in scientific instruments.

Background and objectives: The blood compatibility of indwelling intravascular catheters is facilitated by the use of antithrombogenic materials. Heparin has typically been used for this purpose; however, since heparin-coated catheters are considered combination products, difficulties meeting the relevant Food and Drug Administration safety recommendations have disrupted commercialization. Other issues include coating durability and the occurrence of heparin-induced thrombocytopenia. Polymer coatings are a potential alternative; however, polymer antithrombogenicity in circulating human blood has yet to be demonstrated. The present study aimed to establish the ex vivo antithrombogenicity of a poly-2-methoxyethylacrylate (PMEA) polymer coating applied to a central venous catheter using an artificial human blood circulation system. Methods: The present study used an artificial human blood circulation system to conduct an ex vivo evaluation of the antithrombogenicity of poly-2-methoxyethylacrylate (PMEA)-coated catheters. Human blood samples obtained from volunteer donors were loaded into a circulation system fitted with either a PMEA-coated or uncoated catheter. After 3-h, the catheter was removed and examined using scanning electron microscopy. Protein adsorption on the catheter surface was investigated by shredding the catheter that had contacted the blood inside the circulation system and immersing the pieces in 1 mL of 0.5 N NaOH for 2 days. The amount of protein in the 0.5 N NaOH was determined according to the Lowry method. Results: Adherent fibrin, which forms a sheath on the catheter surface, was observed on uncoated, but not PMEA-coated catheters. Furthermore, the amount of protein adsorption was significantly less with PMEA-coated than uncoated catheters ( p = 0.043). Conclusions: The present findings demonstrated the antithrombogenicity of PMEA-coated catheters in circulating human blood.

В данной статье описывается изучение распространенности зубочелюстных аномалий, в том числе и дистального прикуса среди детей и подростков школьного возраста. В настоящее время широко распространены зубочелюстные аномалии, в том числе дистальный прикус среди детей и подростков. Зубочелюстные аномалии приводят к функциональной патологии морфологических нарушений челюстной области. Изменения возрастно увеличиваются и сопровождаются деформацией лицевой области черепа наряду с эстетическими отклонениями.У больных часто наблюдаются нарушения положения позвоночника,функциональные изменения в системе малого кровообращения и задержка психосомтического развития.Это говорит о ранних нарушениях профилактики и несвоевременном оказании ортодонтической,зубопротезной и комплексной медицинской помощи.В связи с этим важную роль играет эпидемиологическая ситуация по зубной аномалии. исполняют информацию. Диагноз дистальной окклюзии называется боковым сегментом верхнего зубного ряда, расположенным перед боковым сегментом нижнего зубного ряда и появлением между ними дистальной стадии. Лечение и прогноз дистальной окклюзии зубного ряда зависит от возраста больного и характера аномалии [1] The article is devoted to the study of the prevalence of dentition anomalies, including distal occlusion among children and adolescents of school age. Currently, dental anomalies, including distal bite, are widespread among children and adolescents. Dental anomalies lead to functional pathology of morphological disorders of the maxillary region. The changes increase with age and are accompanied by deformation of the facial region of the skull along with aesthetic deviations. Patients often have disorders of the spine position, functional changes in the small blood circulation system and delayed psychosomal development.It tells about the early breaches of the prevention of and untimely provision of orthodontic, prosthodontic and comprehensive medical care.In this regard, an important role is played by the epidemiological situation of dental anomalies. execute information. The diagnosis of distal occlusion is called the lateral segment of the upper dentition, located in front of the lateral segment of the lower dentition and the appearance of the distal stage between them. Treatment and prognosis of distal occlusion of the dentition depends on the patient's age and the nature of the anomalies [1].

A pulsatile circulation system has been built to simulate aortic blood flow. The system has both upstream and downstream compliances and resistances to simulate the elasticity and resistances of blood circulation system. Influences of the compliances and resistances on the pulsatile pressure waveforms have been systematically studied using this system. We found that in absence of the compliances and the downstream resistance, it results in an oversize negative pulsation to the pressure waveforms. The downstream resistance hardly affects the structure of the pressure waveforms, whereas the mean amplitude of pressure increases along with the downstream resistance. The compliance can reduce the peak value of the pressure, which is unrelated to the location of the compliance but related to the elasticity in the system. With fixed upstream system elasticity, the pressure waveform is more stable.
