A10.18 Lack of Association of Serum Interleukin-17 and Interleukin-23 Levels with Disease Activity in Patients with Ankylosing Spondylitis in Latvia
2013
Background Ankylosing spondylitis (AS) is a clinically well-known chronic inflammatory disease of the axial skeleton and peripheral joints. The pathogenesis of this disease still remains a challenge. Determination of cytokine profile and its role involved in AS pathogenesis give an opportunity to extend the targeted therapeutic approach. Interleukin-17 (IL-17) and interleukin-23 (IL-23) are cytokines of interest in the investigation of the pathogenesis of spondyloarthritides although their importance in AS is not clearly defined. Objectives to investigate levels of IL-17 and IL-23 in a group of AS and in a demographically matched group of healthy subjects and its association with the diseas…
Measurement of Agglomeration and Spatial Effects
2009
The aim of the paper is to examine the influence of spatial agglomeration on the employment growth in the sicilian local labor systems. In this paper we want provide a methodological contribution to agglomeration literature. On the base of the hypothesis that the forces of agglomeration do not use up their effects inside of a single SLL but they extend to more wide geographic areas, and their effect fall down on the adjacent territorial partition; we have modified the traditional agglomeration index built by Maurell and Sédillot in 1999, at first, inverting the role of the industry with that one of the area, so we obtain a measure of agglomeration for each area, and then we included a spati…
Disambiguating the soils of Mars
2020
Abstract Anticipated human missions to Mars require a methodical understanding of the unconsolidated bulk sediment that mantles its surface, given its role as an accessible resource for water and as a probable substrate for food production. However, classifying martian sediment as soil has been pursued in an ad hoc fashion, despite emerging evidence from in situ missions for current and paleo-pedological processes. Here we find that in situ sediment at Gusev, Meridiani and Gale are consistent with pedogenesis related to comminuted basalts mixing with older phyllosilicates – perhaps of pluvial origin – and sulfates. Furthermore, a notable presence of hydrated amorphous phases indicates signi…
A spatial analysis of Italian unemployment differences
2008
Using spatial econometric models, this paper focuses attention on the spatial structure of provincial unemployment disparities of Italian provinces for the year 2003. On the basis of findings from the economic literature and of the available socio-economic data, various model specifications including supply- and demand-side variables are tested. Further we use ESDA analysis as equivalent to integration analysis on time series; therefore it is applied on each variable, dependent and independent, involved in the statistical model. The suggestions of ESDA lead us to the most adequate statistical model, which estimates indicate that there is a significant degree of neighbouring effect (i.e. pos…
Uzņēmumu priekšrocības emitējot finanšu instrumentus salīdzinājumā ar citiem finansēšanas veidiem
2018
Darbs ir veltīts uzņēmumu iespējam piesaistit papildu finansējumu finanšu tirgos savas darbības veikšanai un attīstībai. Darba tēmas izvēle ir balstīta uz to, ka viens no uzņēmējdarbības pamatiem un panākumu garantiem ir kapitāla piesaiste un tā efektīva izmantošana. Darba mērķis ir izstrādāt priekšlikumus finansējuma piesaistei uzņēmumam finanšu instrumentu emisijas veidā kā alternatīvu tradicionālajāi kreditēšanai, pamatojoties uz AS HansaMatrix analīzes rezultātiem. Veiktā pētījuma rezultātā ir secināts, ka kapitāla palielināšana caur akciju publisko emisiju ir efektīvs veids kā uzņēmumam piesaistit kapitālu un nostiprināt kapitāla bāzi. Akciju publiskā emisija nodrošina uzņēmuma kopējās…
Open innovation and firms performance: state of the art and empirical evidences from the bio-pharmaceutical industry
2016
The research presented in this paper explores the effect of inbound, outbound and coupled open innovation practices on firms' performances in the biopharmaceutical industry. Specifically, although existing researches on open innovation effectiveness have separately investigated the effect of open innovation practices on innovation and financial performance, this study evaluates the concurrent effect of these practices on both such performance dimensions in a single framework. We state the importance for a manager to explore concurrently the influence of specific open innovation practices both on innovation and economic-financial performance. We empirically test our framework on a sample of …
Elektronisko un parasto cigarešu smēķēšanas akūtas ietekmes uz sirds-asinsrites sistēmas parametriem izvērtējums ikdienas smēķētājiem
2018
Kopš 2008. gada, kad tika izgatavota pirmā elektroniskā cigarete (e-cigarete), strauji pieaug cilvēku skaits, kas sāk tās lietot jeb, kā tas pareizi tiek saukts, veipot (veipošana – no angļu valodas “to vape, vaping, vape”- 'tvaiks' – elektroniskās cigaretes lietošana). Tomēr veipošanas akūta un hroniska ietekme uz cilvēka organisma funkcijām nav detalizēti izpētīta. Pētījums tika veikts ar mērķi noskaidrot divu veidu cigarešu – elektronisko un parasto, smēķēšanas akūtu ietekmi uz sirds un asinsrites sistēmas funkcionālajiem parametriem. Akūts smēķēšanas un veipošanas efekts tika novērtēts 12 klīniski veseliem vīriešiem (24±2 gadi) ar smēķēšanas stāžu 1.5±1.0 pakgadi. Pētījuma ietvaros katr…
Sirds ritma variabilitātes maiņas kuņģa sekrēcijas cefāliskās fāzes laikā
2015
Darbs veltīts autonomās nervu sistēmas eferento ietekmju izpētei uz kuņģa sekrēciju cefāliskās fāzes laikā. Lai novērtētu šīs eferentācijas kāpumus un kritumus, klīniskajā fizioloģijā tiek piedāvāts izmantot SRV novērtēšanas metodi. Vēlējāmies noskaidrot SRV maiņas, novērtējot desmit klīniski veselu pieaugušu cilvēku SRV parametrus „rīta miera” un „laboratorijas miera” apstākļos, kā arī cefāliskās fāzes laikā – 20 minūtēs pēc MMB. Secinājumi: dažādu viena indivīda SRV datu noturīgums ir atšķirīgs, bet cikla garuma atšķirības nepārsniedz 1,5%, RMSSD – 5%. Savukārt „rīta miera” un ”laboratorijas miera” datu salīdzinājums liecina, ka tie atšķiras nenozīmīgi. Eksperimenta ar MMB rezultāti apsti…
THU0476-HPR Perceived influence of health status on sexual activity in ankylosing spondylitis patients:
2013
Background Ankylosing spondylitis (AS) is a chronic, systemic inflammatory rheumatic disease which affects the axial skeleton, but may also affect peripheral joints, tendons and internal organs. The disease which begins in the second or third decade may give rise to significant loss of function and impaired quality of life. Sexuality is an important part of quality of life. Only a few studies have explored this issue in AS patients. In a rheumatoid arthritis (RA) cohort, (74% females, mean (SD) age 56.5 (14.2) years), 1/3 of the patients reported their health statues to have a considerable influence on their sexual activity (1). Objectives To examined the impact of perceived influence of he…
