Abstract:
in the 17th century, william harvey discovered the circulation of the blood, describing at this time the pumping function of the heart and the “in series” disposition of the pulmonary and systemic circulations. these concepts provided the foundation for the development of modern cardiac physiology. during the three centuries that followed the discovery of circulation, many scientists studied and expanded our knowledge of cardiac and pulmonary function. with the description of complex congenital cardiac diseases, in particular functionally univentricular hearts, and with the development of their palliative surgical treatment, we have uncovered another type of cardiac physiology. in these cases, the circulation of the blood is characterized by an “in parallel” disposition of the pulmonary and systemic circulations, with direct venous–arterial connections in the absence of one pumping ventricle.

Abstract:
The lung is unique in its double sources of perfusion from the pulmonary and systemic circulations. One striking difference between the two circulations is the capacity for angiogenesis. The bronchial circulation has a capacity that seems quite similar to all systemic arteries, whereas the pulmonary circulation seems relatively inert in this regard. Extra-alveolar pulmonary arteries can grow somewhat in length, and septal capillaries seem to have the capability of reforming, but these processes do not seem to occur with nearly the same intensity associated with the bronchial arteries. In this review, we emphasize these differences between the two circulations of the lung, anticipating that future research will allow more focused probing into the molecular signaling that regulates the novel mechanistic and pathological pathways of each.

Abstract:
The focus of this review is the role of endocannabinoid system in ocular and systemic circulation. By critically examining preclinical and clinical research, we explore the cannabinoid receptors localization and vascular implications as well as their interaction with other anti-inflammatory drugs. The objective is to transfer knowledge on the use of cannabinoids, specifically their effect on ocular circulation and intraocular pressure, and provide a better understanding of the endocannabinoid system complexity in modulating local and systemic circulations in order to identify potential uses and limitations of cannabinoid-based therapeutics.

Abstract:
αKlotho is primarily known to express as a transmembrane protein. Proteolytic cleavage results in shedding of the extracellular domain which enters systemic circulation. A truncated form of αKlotho resulting from alternative splicing of the αKLOTHO transcript exists and is believed to be secreted, thereby also entering systemic circulation. Existing ELISA methods fail to distinguish between the two circulating isoforms resulting in inconsistencies in assessing circulating αKlotho levels. We have exploited a unique 15aa peptide sequence present in the alternatively spliced secreted isoform to generate an antibody and show that it is able to specifically detect only the secreted Klotho isoform in human plasma. This finding will facilitate in distinguishing the levels of different circulating Klotho isoforms in health and disease and enhance their potential to serve as a biomarker for CKD and other conditions.

Abstract:
Anesthetized rabbits were simultaneously infused with [3H]norepinephrine (NE), [3H]epinephrine (Epi), [3H]dopamine (DA), and [3H]isoproterenol (Iso), and their plasma clearances and fractional extractions across the systemic (ERS), as well as pulmonary (ERP), circulation were determined before and after blockade of uptake1 by desipramine (2 mg/kg). Desipramine reduced the clearance of NE, Epi, and DA by 39, 13, and 14%, respectively, but did not affect Iso clearance. Similar results were obtained with respect to the effects of desipramine on ERS. By contrast, desipramine reduced ERP of NE and DA (which for both amines was markedly lower than ERS) by > 70%; its effect on the very low ERP of Epi was not determinable. Comparison of the desipramine-sensitive components of ERS and ERP indicated that for uptake1 NE was the preferred substrate in the systemic circulation and DA was preferred in the pulmonary circulation. In the absence and presence of desipramine, catechol-O-methyltransferase inhibition had no effect on the clearance of NE, Epi, and DA and decreased Iso clearance by 25%. Hence the contribution by uptake1 to the removal of circulating catecholamines depends on the type of amine and on whether the systemic or pulmonary circulation is considered. Moreover catechol-O-methyltransferase does not appear to contribute to the clearance of NE, Epi, and DA but plays a definite role in the removal of circulating Iso.

Abstract:
ABSTRACTThe circulation of the lung is unique both in volume and function. For example, it is the only organ with two circulations: the pulmonary circulation, the main function of which is gas exchange, and the bronchial circulation, a systemic vascular supply that provides oxygenated blood to the walls of the conducting airways, pulmonary arteries and veins. The pulmonary circulation accommodates the entire cardiac output, maintaining high blood flow at low intravascular arterial pressure. As compared with the systemic circulation, pulmonary arteries have thinner walls with much less vascular smooth muscle and a relative lack of basal tone. Factors controlling pulmonary blood flow include vascular structure, gravity, mechanical effects of breathing, and the influence of neural and humoral factors. Pulmonary vascular tone is also altered by hypoxia, which causes pulmonary vasoconstriction. If the hypoxic stimulus persists for a prolonged period, contraction is accompanied by remodeling of the vasculature, resulting in pulmonary hypertension. In addition, genetic and environmental factors can also confer susceptibility to development of pulmonary hypertension. Under normal conditions, the endothelium forms a tight barrier, actively regulating interstitial fluid homeostasis. Infection and inflammation compromise normal barrier homeostasis, resulting in increased permeability and edema formation. This article focuses on reviewing the basics of the lung circulation (pulmonary and bronchial), normal development and transition at birth and vasoregulation. Mechanisms contributing to pathological conditions in the pulmonary circulation, in particular when barrier function is disrupted and during development of pulmonary hypertension, will also be discussed. © 2016 American Physiological Society.

Full text
Abstract:
Circulating neutrophil activation occurs during cardiac surgery with extracorporeal circulation (ECC) and is implicated in the pathophysiology of inflammatory tissue injury and peri-operative organ dysfunction. However, neutrophil directed antiinflammatory strategies have failed to demonstrate consistent therapeutic benefit indicating that the nature and significance of peri-operative circulating neutrophil activation remains incompletely defined. In particular, conformational activation of the b2 integrin Mac-1 (CD11b/CD18), which is required for neutrophil adhesion competence and facilitation of effector functions, has not previously been investigated during cardiac surgery, and the relative contribution of cellular activation and bone marrow neutrophil recruitment to peri-operative changes in circulating neutrophil phenotype and function is unknown. A novel whole blood flow cytometric technique was used to analyze circulating neutrophil phenotype (total Mac-1, conformationally-active CD11b, CD10, CD16, L-selectin and P-selectin glycoprotein ligand-1) and function in cardiac surgery patients to characterize the nature of changes in Mac-1 expression and activation status, and the effects of relative neutrophil immaturity on circulating neutrophil phenotype and function. The effect of heparin, a known CD11b ligand, on Mac-1 epitope expression was also investigated. Circulating neutrophil numbers observed during ECC were mathematically modeled to determine the acute response of the bone marrow neutrophil reserve to an inflammatory stimulus. Plasma cytokine, chemokine and acute phase mediators were measured in cardiac and lung surgery patients to determine potential regulators of systemic neutrophil recruitment. Neutrophils newlyemergent from the bone marrow were characterized as CD10-/CD16low and exhibited distinct changes in cell surface markers and enhanced functional responses, relative to their more mature CD10+ counterparts. Conformational activation of CD11b occurred peri-operatively and provided a more sensitive measure of circulating neutrophil activation status than changes in total Mac-1 or L-selectin expression, although detection of Mac-1 epitopes was reduced in the presence of heparin. Modeling of circulating neutrophil numbers predicted that post-mitotic maturation time was acutely abbreviated by 8.4 hours during 71 minutes of ECC. Systemic chemokine release occurred with cardiac but not non-cardiac thoracic surgery indicating some specificity of the acute inflammatory response. These findings expand the understanding of peri-operative circulating neutrophil activation and recruitment, and identify potential therapeutic targets to limit neutrophil injurious potential during cardiac surgery with ECC.

Abstract:
Smelter workers who were exposed to air-borne arsenic for a mean of 23 years, and age-matched referents, were examined with clinical, physiological, and neurophysiological methods. Exposure to arsenic in workroom air was estimated to have been around the Swedish occupational limits, which were 500 yg/m before 1975 and 50 yg/ra thereafter. An increased preval ence of Raynaud's phenomenon and a reduced finger systolic blood pressure (FSP) during local and general cooling were found in the smelter workers. Slight, but significant sub-clinical neuropathy, in the form of slightly reduced nerve conduction velocity (NCV) in two or more peripheral nerves, was more common among the arsenic workers than among the referents. There were positive correlations between cumulative exposure to arsenic, reduced NCV in three peripheral motor nerves, and decrease in FSP during cooling. Arsenic levels in urine were 1 ymole/1 (75 yg/1) in the arsenic workers and 0.1 ymole/1 in the referents. In 21 arsenic workers with no or very low exposure to vibra ting hand tools, the FSP during cooling had increased significantly after 3 years wit h the lower arsenic exposure. There was no change in FSP during the summer vacation, whereas urinary levels of arsenic decreased to normal values. Thus there seems to be a slow improvement of finger blood circ ulation which is independent of short-term fluctuations in the exposure to arsenic. No seasonal variation was found in FSP during cooling with the standardized method used. When the NCV-measurements were repeated five years later the difference between arsenic workers and referents had increased, despite the fact that 14 of the 47 arsenic workers had had no exposure to arsenic during the last 1-5 years. These observations indicate, that in subjects with long term exposure to arsenic, sub-clinical neuropathy is not reversible. Ten milligrams of Ketanserin, a serotonin receptor antagonist, was given intravenously to five arsenic workers with cold-induced vasospasm. Skin temperature and FSP during cooling increased significantly with Ketanserin as compared wit h saline solution. After oral treatment, 2 x 40 mg /day for four weeks, no significant increase of FSP during cooling or rise in skin temperature was found in six arsenic workers and eleven patients with Raynaud's phenomenon. The decrease of vasospastic tendency after intravenous injection of Ketanserin indicated that similar mechanisms might operate in arsenic-induced and other types of Raynaud's phenomenon. A general co nclusion from the five studies in this dissertation is that long-term occupational exposure to arsenic has had adverse effects on the peripheral circulation and nerve conduction. The tendency to vasospasm, but not the sub-clinical neuropathy, seemed to be reversible with decreasing exposure.<br><p>S. 1-54: sammanfattning, s. 55-112: 5 uppsatser</p><br>digitalisering@umu

Abstract:
Antinuclear antibodies (ANA) are used in screening and diagnosis of autoimmune connective tissue disorders including systemic lupus erythematosus (SLE). CNS related disorders are prevalent in SLE patients (–80%) and ANA binds specific sites within the brain. To investigate ANA infiltration across the blood-brain barrier (BBB), an ANA injectable Lewis rat model was created using 3 rat groups (saline, ANA, and ANA with histamine; since histamine promotes BBB permeability). ANA serum levels were tested for all three rat groups and rats injected with histamine demonstrated signs of histadelia. Brain slices were obtained and examined for the presence of ANA using immunofluorescence. ANA infiltration across the BBB was observed in ANA injected groups. Though the ANA and ANA histamine groups were significantly different from controls (p<0.034, p<0.030, respectively), no significance between ANA and ANA histamine groups was observed. This model could further be used to examine BBB permeability and potential drug therapy.<br>Department of Physiology and Health Science

Abstract:
Background. Extensive studies have been conducted to simulate blood flow in the human vasculature using nonlinear equations of pulsatile flow in collapsible tube plus a network of vessels to represent the whole vasculature and the cerebral circulation. For non-linear models numerical solutions are obtained for the fluid flow equations. Methods. Equations of fluid motion in collapsible tubes were developed in the presence of gravitational force (Gforce). The Lax-Wendroff and MacCormack methods were used to solve the governing equations and compared both in terms of accuracy, convergence, and computer processing (CPU) time. A modified vasculature of the whole body and the cerebral circulation was developed to obtain a realistic simulation of blood flow under different conditions. The whole body vasculature was used to validate the simulation in terms of input impedance and wave transmission. The cerebral vasculature was used to simulate conditions such as presence of G-force, blockage of Internal Carotid Artery (ICA), and the effects on cerebral blood flow of changes in mean and pulse pressure. Results. The simulation results for zero G-force were in very good agreement with published experimental data as was the simulation of cerebral blood flow. Both numerical methods for solutions of governing equations gave similar results for blood flow simulations but differed in calculation performance and stability depending on levels of G-force. Simulation results for uniform and sinusoidal G-force are also in good agreement with published experimental results, Blood flow was simulated in the presence of a single (left) carotid artery obstruction with varying morphological structures of the Circle of Willis (CoW). This simulation showed significant differences in contralateral blood flow in the presence or absence of communicating arteries in the CoW. It also was able to simulate the decreases in blood flow in the cerebral circulation compartment corresponding to the visual cortex in the presence of G-force. This is consistent with the known loss of vision under increased acceleration. Conclusions. This study has shown that under conditions of gravitational forces physiological changes in blood flow in the systemic and cerebral vasculature can be simulated realistically by solving the one-dimentional fluid flow equations and non-linear vascular properties numerically. The simulation was able to predict changes in blood flow with different configurations and properties of the vascular network.

Introdução. A Aprotinina parece reduzir o uso de transfusões, o processo inflamatório e o dano miocárdico, pós-CEC. Material e Métodos. Estudo prospectivo randomizado em crianças de 30 dias a 4 anos de idade, submetidas à correção de cardiopatia congênita acianogênica, com CEC e divididas em dois grupos, um denominado Controle (n=9) e o outro, Aprotinina (n=10). Neste, a droga foi administrada imediatamente antes da CEC. A resposta inflamatória sistêmica e disfunções hemostáticas e multiorgânicas foram analisadas por marcadores clínicos e bioquímicos. Foram consideradas significantes as diferenças com p<0,05. Resultados. Os grupos foram semelhantes quanto às variáveis demográficas e intra-operatórias, exceto por maior hemodiluição no Grupo Aprotinina. Não houve benefício quanto aos tempos de ventilação pulmonar mecânica, permanência no CTIP e hospitalar, nem quanto ao uso de inotrópicos e função renal. A relação PaO2/FiO2 (pressão parcial de oxigênio arterial/fração inspirada de oxigênio) apresentou queda significativa com 24 h PO, no Grupo Controle. Ocorreu preservação da concentração plaquetária com a Aprotinina enquanto no grupo Controle houve plaquetopenia desde o início da CEC. As perdas sangüíneas foram semelhantes nos dois grupos. No grupo Aprotinina surgiu leucopenia significativa, em CEC, seguida de leucocitose. Fator de necrose tumoral alfa (TNF-) , Interleucinas (IL)-6, IL-8, IL-10, proporção IL-6/IL-10, troponina I cardíaca (cTnI), fração MB da creatinofosfoquinase (CKMB), transaminase glutâmico-oxalacética (TGO) e fração amino-terminal do peptídio natriurético tipo B (NT-proBNP) não apresentaram diferenças marcantes intergrupos. A proporção IL-6/IL-10 PO aumentou no grupo Controle. A lactatemia e acidose metabólica pós-CEC foi mais intensa no grupo Aprotinina. Não houve complicações com o uso da Aprotinina. Conclusão. A Aprotinina não minimizou as manifestações clínicas e os marcadores séricos de resposta inflamatória sistêmica e miocárdicos, mas preservou quantitativamente as plaquetas.<br>Introduction. Aprotinin seems to reduce the need for transfusion, the inflammatory process and myocardial damage after extracorporeal circulation (ECC). Material and Methods. A prospective randomized study was conducted on children aged 30 days to 4 years submitted to correction of acyanogenic congenital heart disease with ECC and divided into two groups: Control (n=9) and Aprotinin (n=10). In the Aprotinin Group the drug was administered immediately before ECC and the systemic inflammatory response and hemostatic and multiorgan dysfunctions were analyzed on the basis of clinical and biochemical markers. Differences were considered to be significant when P<0.05. Results. The groups were similar regarding demographic and intraoperative variables, except for a greater hemodilution in the Aprotinin Group. The drug had no benefit regarding time of mechanical pulmonary ventilation, permanence in the postoperative ICU and length of hospitalization, or regarding the use of inotropic drugs and renal function. The partial arterial oxygen pressure/inspired oxygen fraction ratio (PaO2/FiO2) was significantly reduced 24 h after surgery in the Control Group. Platelet concentration was preserved with the use of Aprotinin, whereas thrombocytopenia occurred in the Control Group since the beginning of ECC. Blood loss was similar for both groups. Significant leukopenia was observed in the Aprotinin Group during ECC, followed by leukocytosis. Tumor necrosis factor alpha (TNF-), interleukins (IL)-6, IL-8, IL-10, IL-6/IL-10 ratio, cardiac troponin I (cTnI), creatine kinase MB fraction (CKMB), glutamic-oxaloacetic transaminase (GOT) and the aminoterminal fraction of natriuretic peptide type B (NT-proBNP) ndid not differ significantly between groups.The postoperative IL-6/IL-10 fraction increased significantly in the Control Group. Post-ECC blood lactate concentration and metabolic acidosis was more intense in the Aprotinin Group. There were no complications with the use of Aprotinin. Conclusion. Aprotinin did not minimize the clinical manifestations or serum markers of the inflammatory, systemic and myocardial response, but quantitatively preserved the platelets.

Abstract:
Le controle aerien doit assurer la separation des avions en minimisant les retards. Pour des raisons d'efficacite, des systemes d'evitement automatiques sont envisages avec, la ou le trafic est le moins dense, un transfert de responsabilites des controleurs aux avions. Un systeme d'evitement doit proposer des trajectoires d'evitement (assurant la separation). Il peut etre centralise ou embarque (chaque avion genere sa trajectoire). Nous presentons deux methodes pour generer des trajectoires d'evitement normalisees (definies par des instants de manuvres et des sens de deviation) : un algorithme branch and bound utilisant des methodes d'intervalles et un algorithme a*. Deux approches differentes de chacune de ces methodes sont decrites et testees sur des cas-tests de conflits. L'approche globale genere simultanement les trajectoires de tous les avions (systeme centralise). L'approche sequentielle les genere successivement, selon un ordre de priorite (forme sequentielle d'un systeme embarque). Des trajectoires de bonne qualite sont obtenues. Cependant, l'approche globale des methodes d'intervalles est tres couteuse en temps de calcul et celle de l'algorithme a*, en memoire. L'efficacite des approches sequentielles depend de l'ordre de priorite. L'algorithme a*, contrairement aux methodes d'intervalles, permet de considerer des vitesses variables (avions en montee ou en descente). Testee sur un simulateur de trafic reel, sa version sequentielle donne de bons resultats. Une methode de generation de trajectoires par commande continue (forme reactive d'un systeme embarque) est presentee ensuite. A chaque instant le cap de l'avion est modifie au moyen d'un reseau de neurone. L'apprentissage des reseaux de neurone se fait par algorithme genetique. Trois modes d'apprentissages sont compares : utilisation de bases d'apprentissage fixes et renouvelees, et coevolution. Les meilleurs resultats sont obtenus avec les bases renouvelees.

Abstract:
The aim of this study is to develop a distributed model of the entire systemic arterial tree, coupled to a heart model and including a detailed description of the cerebral arteries. Distributed models of the arterial tree have been studied extensively in the past (Avolio [1]; Cassot et al [2]; Meister [3]; Schaaf and Abbrecht [4]; Stergiopulos et al [5]; Westerhof et al [6]; Zagzoule and Marc-Vergnes [7]), however, no model has been developed so far that offers a physiologically relevant coupling to the heart and includes the entire cerebral artery network.

Abstract:
The subject of the study is the ideological, financial, economic and socio-social conditions of the publishing house and the editorial board of the magazine “New Pathway” Winnipeg period 1941-1977. The main objectives is to determine the peculiarities of the conditions of publishing a Ukrainian magazine in exile, which provides for the systematization and introduction into scientific circulation of factual material on creative and material activities of the “New Pathway” and socio-political environment that influenced the information and ideological and business policy of the publication. The basis of the research methodology is axiological, cultural, systemic approaches; methods of historicism, analysis, synthesis, generalization were used. The study provides not only a description of the historical path of the publication in this period, but also the reasons for miscalculations and successes, both financial and economic and socio-political, which allowed not only to stay in the information field and market for more than ninety years, technical circumstances of its existence, the political struggle in the new wave of emigration after World War II, changes in demographic and linguistic situation among the Ukrainian diaspora in Canada. The reasons for the situational increase and decrease in the activity of the publication’s subscribers were identified; the mechanisms of expanding the readership, attracting new readers and authors are analyzed; confirmed that the efforts of editors and directors of the publishing house at the initial stage of the Winnipeg period created and strengthened the material and technical base of the publishing house, conducted advertising campaigns and direct work to attract new subscribers and readers; The significance of the study is that for the first time in Ukraine the information about the Winnipeg period of the Ukrainian-Canadian weekly “New Pathway”, its financial and financial problems and creative and editorial successes was analyzed and summarized, thus filling another page in the history of Ukrainian diaspora periodicals.

Full text
Abstract:
The research was conducted in a circulating fluidized bed having diameter and height of riser of 5 and 200 cm., respectively, at ambient temperature and pressure. The objective was to study hydrodynamics of mixed-feed between sand and various biomasses including rice husk, sawdust, and bagasse at 50% by volume. The air flow rate was in the range of 4.2-5.7 m/s. The velocity of sand in the riser was obtained by using a high speed camera and an image processing software. The results showed that at the lowest gas velocity the velocities of sand in the mixture were higher than those in the single system. Howerver at the highest gas velocity it was found that the sand velocity in the mixture of sand and sawdust was the highest among all mixtures. Next the experiment was conducted by means of mixture of glass beads and rice husk. It was found that in the bottom part of the riser the velocities of glass beads in the mixing system were lower than those in the single system. Nevertheless, the velocities of glass beads in both systems reached similar values at the top of the riser.
