Description:
The article provides information on the finding of a previously unknown Czech-language printed book from 1623, the work of the Prague typographer Pavel Sessius and an unknown Czech translator, who used the initials M.W.S. The unique printed book was discovered in the collections of the Österreichische Nationalbibliothek in Vienna. Besides the textual part, comprising quotations from the Bible and short prayers, it includes a title border with the motif of Calvary, inspired by earlier domestic sources, and above all sixteen woodcut copies of selected scenes from the graphic cycle The Small Passion by the German painter and graphic artist Albrecht Dürer. The article describes the typography and illustration aspects of the printed book in detail. The author also tries to identify any foreign models for it., David Mach., and Obsahuje bibliografické odkazy

31355. Tiskař a briefmaler Michael Peterle (1537–1588)

Subject:
Michael Peterle Snr, woodcut, illustration, printing workshop, and 16th century
Language:
Czech
Description:
The article deals with the printer and Briefmaler (letter painter) Michael Peterle (1537–1588), who is also considered to be a woodcutter by Czech book scientists. It focuses on his pictorial broadsides and illustrated books and analyses the morphological features of the extant woodcuts. It has reached the conclusion that Peterle’s woodcutting activities cannot be proved. Apart from the art-historical perspective, it brings a number of new facts associated with Peterle’s printing activities: for instance, it documents the financial background of Prague printers in the 1570s and 1580s.

Language:

Description:
Vasoactive intestinal peptide (VIP) is a neuropeptide released from the autonomic nerves exerting multiple antiinflammatory effects. The aim of the present study was to investigate the impact of severe sepsis and hemofiltration in two settings on plasma and tissue concentrations of VIP in a porcine model of sepsis. Thirty-two pigs were di vided into 5 groups: 1) control group; 2) control group with conventional hemofiltration; 3) septic group; 4) septic group with conventional hemofiltration; 5) septic group with high-volume hemofiltration. Sepsis induced by faecal peritonitis continued for 22 hours. Hemofiltration was applied for the last 10 hours. Hemodynamic, inflammatory and oxidative stress parameters (heart rate, mean arterial pressure, cardiac output, systemic vascular resistance, plasma concentrations of tumor necrosis factor- α , interleukin-6, thiobarbituric acid reactive species, nitrate + nitrite, asymmetric dimethylarginine) and the systemic VIP concentrations were measured before faeces inoculation and at 12 and 22 hours of peritonitis. VIP tissue levels were determined in the left ventricle, mesenteric and coronary arteries. Sepsis induced significant increases in VIP concentrations in the plasma and mesenteric artery, but it decreased peptide levels in the coronary artery. Hemofiltration in both settings reduced concentrations of VIP in the mesenteric artery. In severe sepsis, VIP seems to be rapidly depleted from the coronary artery and, on the other hand, upregulated in the mesenteric artery. Hemofiltration in both settings has a tendency to drain away these upregulated tissue stores which could result in the limited secretory capacity of the peptide., J. Kuncová ...

Description:
a1_The tissue factor plays a crucial role in initiating blood coagulation after plaque rupture in patients with acute coronary syndrome. It is abundant in atherosclerotic plaques. Moreover, P-selectin, some cytokines, endotoxin and immune complexes can stimulate monocytes and induce the tissue factor expression on their surface. The aim of the study was to compare plasma levels of the tissue factor, tissue factor pathway inhibitor, P-selectin, E-selectin and ICAM-1 in patients with acute myocardial infarction, unstable angina pectoris, stable coronary artery disease and normal control subjects. In addition, plasma levels of the tissue factor, tissue factor pathway inhibitor, P-selectin, E-selectin and ICAM-1 were measured in the blood withdrawn from the coronary sinus in a subgroup of patients with unstable angina pectoris and stable coronary artery disease in which the difference between concentrations in the coronary sinus and systemic blood was calculated. A significant increase in tissue factor pathway inhibitor plasma levels was detected in patients with acute myocardial infarction (373.3±135.1 ng/ml, p<0.01) and unstable angina pectoris (119.6±86.9 ng/ml, p<0.05) in contrast to the patients with stable coronary artery disease (46.3±37.5 ng/ml) and normal subjects (45.1±14.3 ng/ml). The plasma levels of tissue factor pathway inhibitor were significantly increased both in the coronary sinus and systemic blood in the patients with unstable angina pectoris. There was only a non-significant trend to higher plasma levels of the tissue factor in patients with acute myocardial infarction and unstable angina pectoris as compared to the patients with stable coronary artery disease and normal subjects, the values being 129.1±30.2 pg/ml, 130.5±57.8 pg/ml, 120.2±45.1 pg/ml and 124.9±31.8 pg/ml, respectively., a2_Plasma levels of soluble P-selectin was only slightly, but non-significantly higher in patients with unstable angina pectoris and stable coronary artery disease (184.2±85.4 ng/ml and 201.6±67.9 ng/ml, respectively) than in patients with the acute myocardial infarction (157.4±88.4 ng/ml) or normal subjects (151.4±47.1 ng/ml). The difference in plasma levels of soluble ICAM-1 between the blood withdrawn from the coronary sinus and systemic circulation correlated significantly with the corresponding difference in plasma levels of soluble P-selectin and E-selectin. In conclusion, the tissue factor and the tissue factor pathway inhibitor play a crucial role in the initiation of arterial thrombosis. The tissue factor pathway inhibitor levels are increased both in the systemic blood and in the coronary sinus of patients with the acute coronary syndrome., M. Malý, J. Vojáček, V. Hraboš, M.

31359. Tissue specific and variable collagen proliferation in Swiss albino mice treated with clenbuterol

Language:

Description:
Chronic administration of clenbuterol, a beta-adrenoceptor agonist (2 mg/kg body weight/day for 30 days) to mice resulted in an increased body mass. Measurement of dry tissue mass suggested a protein anabolic effect in the gastrocnemius and heart. Quantitative estimation of collagen content, a non-contractile element as calculated from hydroxyproline assay revealed its proliferation in the gastrocnemius, cardiac ventricle, intestine and to some extent also in the kidney. Clenbuterol did not induce collagen proliferation in non-muscle tissues such as the lungs and liver. Histopathological examination of sections from treated ventricles showed an extensive collagen infiltration in the subendocardium and at myonecrosis sites.

Language:

Description:
Currently-used mechanical and biological heart valve prostheses have several disadvantages. Mechanical prostheses, based on carbon, metallic and polymeric components, require permanent anticoagulation treatment, and their usage often leads to adverse reactions, e.g. thromboembolic complications and endocarditis. Xenogenous and allogenous biological prostheses are associated with immune reaction, thrombosis and degeneration, and thus they have a high rate of reoperation. Biological prostheses of autologous origin, such as pulm onary autografts, often burden the patient with a complicated surgery and the risk of reoperation. Therefore, efforts are being made to prepare bioartificial heart valves with an autologous biological component by methods of tissue engineering. They should be biocompatible, durable, endowed with appropriate mechanical properties and able to grow with a child. For this purpose, scaffolds composed of synthetic materials, such as poly(lactic acid), poly(caprolactone), poly(4-hydroxybutyrate), hydrogels or natural polymers, e.g. collagen, elastin, fibrin or hyaluronic acid, have been seeded with autologous differentiated, progenitor or stem cells. Promising results have been obtained with nanostructured scaffolds, and also with cultivation in special dynamic bioreactors prior to implantation of the bioartificial grafts into an animal organism., E.
