Noguruma un gulētiešanas laika novilcināšanas saistība ar prokrastināciju skolotājiem
2016
Pētījuma mērķis bija noskaidrot sakarību kā augstāki prokrastinācijas kā iezīmes un noguruma rādītāji prognozē gulētiešanas laika novilcināšanu. Dati tika ievākti Rīgas un Ogres novada skolās elektroniski. Tika aptaujāti N=229 skolotāji ar vidējo vecumu M=43,66 (SD=11,57), no kuriem 26 bija vīrieši un 203 sievietes. Tika izmantota: “Prokrastinācijas aptauja” (Lay, 1986) un divas aptaujas, kuras tiek adaptētas šī maģistra darba ietvaros “Gulētiešanas laika prokrastinācijas skala” (Adriaanse, De Ridder, Evers, & Kroese, 2014), “Noguruma aptauja” (Chalder et al., 1993). Tika izvirzīta hipotēze - nogurums un prokrastinācija pozitīvi prognozē gulētiešanas laika novilcināš…
Prostatas biopsijas ar attēlu sapludināšanas metodi rezultātu analīze atkarībā no PI-RADS klasifikācijas
2021
Ievads. Prostatas audzējs (PCa) pēc izplatības vīriešiem ierindojas 2. vietā Latvijā. Jaunveidojumu diagnostikā pastāv zelta standarts – transrektālas ultraskaņas vadīta (TRUS) biopsija, tomēr PCa bieži vien ir multifokāls, bet biopsijas laikā tiek paņemta maza prostatas audu daļa. Ir pieejama cita biopsijas metode- ar attēlu sapludināšanas metodi (fusion-biopsija), kad TRUS-biopsija tiek veikta vienlaicīgi ar magnētiskās rezonanses izmeklējuma (MR) palīdzību. Šajā pētījumā tika noskaidrota, prostatas attēlveidošanas ziņošanas un datu vērtēšanas sistēmas (PI-RADS) pēc daudzparametru MR (mpMR) rādītāju korelācija ar histopatoloģiskajām atbildēm pēc fusion-biopsijas. Pētījuma mērķis. Izvērtēt…
Non-Saccharomyces Yeasts: An Enzymatic Unexplored World to be Exploited
2019
Abstract Fermentation, to obtain alcoholic beverages, is a process which implies the interaction of various microorganisms. This metabolic process is due to the action of yeasts, which can be divided into two groups, the Saccharomyces yeasts, particularly S. cerevisiae, and the non-Saccharomyces yeasts. Although they are considered spoilage microorganisms of the fruits, non-Saccharomyces yeasts possess some interesting applied characteristics and can be used in food industry. Some of the compounds produced by these microorganisms may be beneficial and improve the characteristics of the fermented beverages. In this chapter, recent advances in glycosidase, xylanase, lipase, esterase, protease…
Kinetic analysis and molecular modeling of the inhibition mechanism of roneparstat (SST0001) on human heparanase
2016
Heparanase is a β-d-glucuronidase which cleaves heparan sulfate chains in the extracellular matrix and on cellular membranes. A dysregulated heparanase activity is intimately associated with cell invasion, tumor metastasis and angiogenesis, making heparanase an attractive target for the development of anticancer therapies. SST0001 (roneparstat; Sigma-Tau Research Switzerland S.A.) is a non-anticoagulant 100% N-acetylated and glycol-split heparin acting as a potent heparanase inhibitor, currently in phase I in advanced multiple myeloma. Herein, the kinetics of heparanase inhibition by roneparstat is reported. The analysis of dose-inhibition curves confirmed the high potency of roneparstat (I…
Proteomics of Galápagos Marine Iguanas Links Function of Femoral Gland Proteins to the Immune System
2020
Femoral glands secrete a wax-like substance on the inner side of lizard hind legs, which is thought to function as a mode of chemical communication. Though the minor volatile fraction is well studied, the major protein fraction remains enigmatic. Here, we use proteomics to analyze proteins in femoral gland secretions of the Galápagos marine iguana. Although we found no evidence for proteins and peptides involved in chemical communication, we found several immune-regulatory proteins which also demonstrate anti-microbial functions. Accordingly, we show that femoral gland proteins and peptides function as a barrier against microbial infection and may prevent the rapid degradation of volatile s…
Roman quarries of the Iberian Peninsula: "Anasol" and "Anasol-type".
2007
The Iberian peninsula is rich in marble, both white and coloured, of excellent quality, used in the past (Pliny NH, XXXVI, II) and also at the present time as material for building and decoration. Many types of these marbles are similar to some, better known, Greek, Italian, Egyptian and Asian marbles. During the Roman Empire “ marmor carystium ” was extensively used. Taking into account the great similarity of this marble with the “ anasol ” and “ anasol ”-types mined in Spain and Portugal, this work presents a minero-petrographic, chemical and geochemical characterisation of these lithotypes, aiming at finding parameters to distinguish them from the better-known Greek and Italian “ cipoll…
Distinction Between Euthanasia and Valid Medical Decision and Its Impact on Unborn Life
2014
The article is dedicated to revealing those aspects which allow to distinguish euthanasia from valid medical decisions which are made by physicians within the scope of the care of incurably ill persons and their impact on the issue regarding yet unborn life. As in separate forms of euthanasia and the realisation of its kinds, analogies of valid medical procedure are observed, the article analyses the most common cases when the decision made by the physician and the resultant action or omission of the action binds him/her to unjustified criminal judgement by revealing the fundamental features which approve the legitimacy of the decision made, thus distinguishing it from the criminal offence,…
External iliac artery pseudoaneurysm complicating renal transplantation
2009
Objective: To assess the etiology, management and outcome of iliac pseudoaneurysms following renal transplantation. Methods: Eleven patients who underwent repair between 1982 and 2007 were identified. Five (Group 1) presented pseudoaneurysm at the anastomosis of the donor renal and native iliac arteries, and six (Group 2) presented iliac pseudoaneurysm following transplant nephrectomy. Intraoperative cultures and immunohistochemical examinations were obtained from all surgical cases to determine the existence of a relationship between infection or transplant rejection and pseudoaneurysm formation. Results: Endovascular repair (EVR) was used to treat three patients, while eight patients unde…
Aortic valve-sparing root replacement from inside the aorta using three Dacron skirts preserving the native Valsalva sinuses geometry and stabilizing…
2009
We present an alternative idea for valve-sparing technique combining the advantages of the reimplantation and the benefits of the remodeling techniques. We replace the sinuses of Valsalva using three Dacron skirts from inside of the aorta. The physiological anatomy of the Valsalva sinuses and their dynamic properties are preserved and the aortic commissures displacement avoided. The distal rim of each Dacron skirt was anchored to the aorto-ventricular junction using Ticron (2-0) U stitches placed from the ventricular side to the aortic side. We stabilize the base of the aortic annulus to prevent future dilation.
Change from Hybrid to Fully Minimally Invasive and Robotic Esophagectomy is Possible without Compromises.
2018
Background The incidence of esophageal carcinoma is increasing in the western world, and esophageal resection is the essential therapy. Several studies report advantages of minimally invasive esophagectomies (MIEs) versus conventional open procedures (OPs). The benefits of the use of fully MIE or robot-assisted MIE (RAMIE) compared with the hybrid approaches (laparoscopic gastric preparation and open transthoracic esophagectomy) remain unclear. Methods Between July 2015 and August 2017, the data of 75 patients with esophageal carcinoma were prospectively registered. Of the 75 patients, 25 treated with a hybrid MIE (hybrid), 25 with total MIE (MIE), and 25 with RAMIE. All patients were oper…
