No full textThe aim - to assess the carotid artery angioplasty and stenting early and late results and influencing factors. Methods. The study assessed CAS procedures performed in 2006-2013. A total of 227 procedures performed in 211 patients, of which 156 (75.3%) males and 55 (24.7%) females. Results. The study revealed that CAS procedure duration among patient with 3 aortic arch type was significantly longer and the microemboli protection systems were used more frequently. Protection systems were used more frequently when the CAS procedure lasted longer. Protection systems in CAS procedure was used in 70.9% patients. In men and younger patients protection system has been used more frequently. Microemboli in the protection systems have been identified by 17.6% patients and were more determined using the EZ FilterWire and Emboshield-NAV protection system. Increased right ICA stenosis was more common in patients who smoke, and left ICA with a history of myocardial infarction and smoking. Protection system was often used in patients who have had severe left ICA stenosis. The lethality rate in the early post procedural period among men and women was 1.2% and 1.8%, and in 2-year period was 18.7% and 28.6%, respectively. The lethality rate during 2-year period, which have been used for protective systems have been lower. The possibility to experience complications (stroke or TIA) increased 3 aortic arch type and the right common carotid artery stenosis, reduced protection systems using. Focal, linear, Ipsi- and bilateral ischemic cerebral injury was diagnosed less frequently in patients who have undergone Emboshield-NAV type of protection. During 1 year after the CAS cognitive and motor functions worsening, but no significant improvement was obtained. Before CAS poorer cognitive function compared with the control group, was established in symptomatic patients. Both symptomatic and asymptomatic patients before the CAS significantly lower by motor tasks as compared with the control subjects

Objective
To determine what is the rate, type, and the best treatment of local femoral access complications after interventional cardiology catheterisation procedures through percutaneous femoral artery puncture.
Materials and methods
Retrospective analysis of 166 patient medical records was carried out. All the patients underwent coronarography for the suspected coronary artery disease. All of them from 2007 to 2011 developed local femoral access complications. All complications were diagnosed and treated by vascular surgeons.
Results
The study group consisted of 96 (57.8%) women and 70 (42.2%) men. The average age of the patients was 69.1 years (±11.4 years). Limb ischemia was determined in 63 patients (38%). After catheterisation due to cardiovascular pathology, femoral artery pseudoaneurysm developed in 162 patients (97.6%), arteriovenous fistula in 3 patients (1.8%), and massive hematoma in 1 patient; 111 patients (66.9%) were treated conservatively and 55 (33.1%) surgically. The surgically treated group consisted of 37 women (67.3%) and 18 men (32.7%). The average age of surgically treated patients was 69.9 (±10) years. Pseudoaneurysm removal and venous patch plasty were performed in 33 patients (60%). The removal of blood clots and direct suture of arterial defects were performed in 22 patients (40%).
Conclusions
166 patients (0.706%) developed local vascular complications after cardiovascular interventions through the femoral artery. Pseudoaneurysm was the most common complication after femoral artery catheterisation. Conservative treatment was successful in 111 patients (66.9%). Local vascular complications of the puncture site were more common in patients with a peripheral arterial disease (p < 0.01).

ELEKTRONINIS POSŪKIS: NUO FIZINIO MIESTO LINK E-TOPOS MIESTO
No full textStraipsnyje nagrinėjamas „elektroninis posūkis“, kuris akivaizdžiai pastebimas filosofinėje urbanistinių temų analizėje. Greta neutralaus miesto topos aprašymo, utopinių ir distopinių miesto vizijų susiformuoja teorinis diskursas, aprašantis miestą per e-topos prizmę. Naujasis diskursas filosofinėje miesto analizėje akcentuoja medijų poveikio miesto funkcionavimui bei globalizacijos procesų komponentą. Atskleidžiama, kaip „elektroninis posūkis“ pakeitė miestiečio, namų ir miesto erdvių interpretacijas. Parodoma, jog „elektroninio posūkio“ teorijose miestiečio sąmoningumas siejamas su skaitmeniniais nervų sistemos parametrais, namai aprašomi kaip komunikacijos tinklais su pasauliu sujungti atviri dariniai, o miestas suprantamas ne per fizines struktūras, bet per dinamiškas srautų erdves.
Pagrindiniai žodžiai: miestas, e-topos, srautų erdvė.
Electronic Turn: From Physical City towards e-topos City
Nerijus Milerius
Summary
The author deals with the “electronic turn” which is evidently present in philosophical analysis of urban subjects. As the effect of such turn, along with three traditional theoretical discourses, neutral descriptive analysis of the urban topos, utopias and dystopias, a new urban discourse of e-topos has been establishing itself. The new urban discourse lays stress on the outcomes of the media and the processes of globalization for the city life and its structures. In the artic le, an essential shift in the interpretation of citizen, home and urban spaces is revealed. Theories contributing to “electronic turn” analyze urban citizen through the prism of digital parameters of the nervous system, describe the home as the open units integrated into the communication network, reveal the city not through its material structures, but through the dynamic space of flows.
Keywords: city, e-topos, space of flows.

Tributalizmo koncepcija: S. Amino, J. Haldono ir H. H. Stahlio sampratų lyginamoji analizė
No full textBy this article, the author wants to revive discussion about Marxist schemas of social development and their applicability for constructing models of universal history. There are attitudes of three scholars presented in the current text: Samir Amin, who is known in the Western historiographical tradition as a main creator and promoter of the concept of the tributary mode of production; John Haldon, who paid quite much attention to the mentioned concept and dedicated his entire book to this issue; and Henri H. Stahl, who created an original alternative approach to the issue of tributalism.
The author rejects J. Haldon\u27s concept of mode of production as too narrow (in fact, J. Haldon identifies mode of production with mode of exploitation). The author proposes a wider definition of mode of production, which is based on the analysis of Karl Marx\u27s texts. According to the author, the most important elements of mode of production are the exploitative subject (it is defined by property of conditions of production, which realizes as a social power) and productive/obligatory unit, which can be manifested as a household of an individual direct producer or as a community. The author proposes the following principled classification based on his conception of mode of production:
A proprietor of land is a monarch/state, and a productive/obligatory unit is a community (of Asiatic/Slavonic type);
A proprietor of land is a monarch/state, and a productive/obligatory unit is a household of an individual direct producer;
Proprietors of land are private landowners, and a productive/obligatory unit is a community (of Asiatic/Slavonic type);
Proprietors of land are private landowners, and a productive/obligatory unit is a household of an individual direct producer.
The most important conclusions of the author\u27s are as follows:
H. H. Stahl\u27s statement that there were alternatives in the social development of precapitalist societies is definitely reasonable.
Keeping in mind controversies among the presented conceptions of tributalism, the author emphasizes that, at the moment, the question of the typology of antagonistic precapitalist societies remains open; so further researches and discussions are necessary.
As a point of departure for further researches and discussions the author proposes his principled classification of antagonisticprecapitalist societies based on criteria of an exploitative subject and a productive / obligatory unit
New photoplethysmographic parameter reveals blunted endothelium-dependent response to sulbutamol in coronary and hypertensive patients
No full textBackground. Analysis of photoplethysmographic digital volume pulse (DVP) parameter inflection point (IP) before and after inhaled salbutamol is used for the noninvasive assessment of endothelial function. Our aim was to determine if there are other more informative DVP parameters. Methods. The DVP was recorded in 62 patients with coronary heart disease
(CHD) (n = 20), arterial hypertension (n = 22) and healthy volunteers (n = 20) before and after 400 g salbutamol inhalation. Measerument of IP decrease after salbutamol as well as the new derivative parameter – the ratio of salbutamol induced maximal IP decrease with maximal prolongation of peakto-peak time (PPT) between forward systolic and reflected waves (IP/ PPT)
– were applied for analysis of DVP curves.
Results. Better discrimination between the groups was found when applying the new parameter IP/ PPT compared with the traditional IP parameter. IP/ PPT was significantly higher in patients with arterial hypertension (1.79 2.74 vs. 0.23 0.19, p = 0.01) and with CHD (2.88 3.01 vs. 0.23 0.19, p 0.0013) as compared with the control subjects. No significant
difference between the decrease of IP after salbutamol in patient groups with arterial hypertension and CHD was found when compared them with the control group (10.48 6.88%, 11.14 11.10% and 15.12 16.03% respectively, p = 0.3). The prolongation of PPT was significantly greater in control group compared with arterial hypertension group (93.12 83.79 vs.
37.79 47.50, p = 0.03) but not in CHD patients (93.12 83.79 vs. 60.86 60.26, p = 0.2).
Conclusion. The new DVP parameter IP/ PPT for photoplethysmographic analysis of salbutamol-induced changes could be suggested for evaluation of endothelial function
Photoplethysmographic assessment of the pulse wave: a blunted response to salbutamol in arterial hypertension and coronary heart disease
No full textObjectives: A systemic vascular effect of beta2-adrenergic agonist salbutamol is partially mediated through the L-arginine–NO pathway. Therefore, the attenuation of photoplethysmographic digital volume pulse parameters under salbutamol inhalation could be used for the evaluation of endothelial function. The aim of the study was to estimate the vascular response to salbutamol in patients with arterial hypertension (AH) and coronary heart disease (CHD). Design and Methods: Totally 71 subjects were studied: 30 patients with AH, 26 patients with CHD and 15 healthy controls (C). All the subjects underwent the detailed clinical assessment and photoplethysmographic evaluation of the pulse wave response to 400 µg salbutamol inhalation. A portable photoplethysmograph Micro MedicalMP2000 ( Gillingham , Kent , United Kingdom ) was used for digital volume pulse analysis..

Investigation of sewage sludge pyrolysis products and residual solid material influence to fibre hemp biomass production.
No full textThe quantities of sewage sludge generated in the treatment plants already pose serious problems related to its storage and use. The Article 14 of the Urban Waste Water Treatment Directive 91/271/EEC specifies, “Sewage sludge from waste water treatment shall be re-used whenever appropriate. Disposal routes shall minimize the adverse effects on the environment “. Therefore, priority is given to the reuse of sewage sludge, rather than disposal it to landfills or storage plants. The analysis of scientific literature related to the quantities of sewage sludge and its chemical composition, possibilities of its use in thermal process and possibilities of residual product use in other areas as a raw material was carried out by the author of dissertation. Sewage sludge samples were collected from the major water treatment systems in Lithuania during the preparation of dissertation. After investigation of their chemical quality, author selected sewage sludge samples from a small city (Šilutė) for a more detailed research. Author designed and constructed a pyrolysis stand where he carried out thermal decomposition (pyrolysis) of sewage sludge. Solid fraction as char obtained from sewage sludge was used in experimental research on cultivation of fibre hemp (Canabis sativa L.). In order to assess the regularities of distribution of heavy metals, alkaline earth metals and alkaline metals as well as of non-metals the author carried out chemical analysis of sewage sludge, sludge pyrolysis products and gifferent parts of fibre hemp (roots, stem, leaves). According to the results author found distribution of elemental migration in the course of the application of the principle of sustainable use of sewage sludge
