Mast cells as protectors of health.
2019
Mast cells (MCs), which are well known for their effector functions in T(H)2-skewed allergic and also autoimmune inflammation, have become increasingly acknowledged for their role in protection of health. It is now clear that they are also key modulators of immune responses at interface organs, such as the skin or gut. MCs can prime tissues for adequate inflammatory responses and cooperate with dendritic cells in T-cell activation. They also regulate harmful immune responses in trauma and help to successfully orchestrate pregnancy. This review focuses on the beneficial effects of MCs on tissue homeostasis and elimination of toxins or venoms. MCs can enhance pathogen clearance in many bacter…
Typpiseostettu grafeeni
2017
Tässä Pro Gradu -tutkielmassa perehdytään typpiseostetun grafeenin rakenteeseen, ominaisuuksiin, karakterisointiin, valmistukseen ja sovelluksiin. Valtaosa typpiseostetun grafeenin ominaisuuksista pohjautuu puhtaaseen grafeeniin, joten myös sitä käsitellään samalla. Typpi voi sitoutua grafeenihilaan eri tavoilla, joten mahdolliset konfiguraatiot ja niiden vaikutus rakenteeseen ja grafeenin ominaisuuksiin käydään läpi. Spektroskopia ja karakterisointi -kappaleessa keskitytään eniten puhtaan ja typpiseostetun grafeenin ramanspektroskopiaan ja röntgensädefluoresenssispektroskopiaan (XPS). Valmistuskeinot-kappaleessa kerrotaan lyhyesti grafeenin yleisimmistä synteesimenetelmistä ja käydään läpi…

On Line Validation Exercise (OLIVE): A Web Based Service for the Validation of Medium Resolution Land Products. Application to FAPAR Products
2014
International audience; The OLIVE (On Line Interactive Validation Exercise) platform is dedicated to the validation of global biophysical products such as LAI (Leaf Area Index) and FAPAR (Fraction of Absorbed Photosynthetically Active Radiation). It was developed under the framework of the CEOS (Committee on Earth Observation Satellites) Land Product Validation (LPV) sub-group. OLIVE has three main objectives: (i) to provide a consistent and centralized information on the definition of the biophysical variables, as well as a description of the main available products and their performances (ii) to provide transparency and traceability by an online validation procedure compliant with the CEO…
Psihopātijas iezīmju, vardarbības pieredzes ģimenē un vardarbīgu videospēļu spēlēšanas saistība pusaudžiem
2016
Pētījuma mērķis ir noskaidrot kā psihopātijas iezīmes pusaudžiem ir saistītas ar vardarbīgu videospēļu spēlēšanu un vardarbības pieredzi bērnībā, un vai saistība starp psihopātijas iezīmēm un negatīvu bērnības pieredzi ir ciešāka, nekā starp psihopātijas iezīmēm un vardarbīgu videospēļu spēlēšanu. Pētījumā piedalījās 109 respondenti vecumā no 15-17 gadiem. Datu iegūšanai tika izmantota datorspēļu atpauja (Puriņa, 2010), Viseiropas Spēļu informācijas mājaslapas – The Pan-European Game Information (PEGI) sistēmas novērtējums, Jauniešu psihopātisko iezīmju aptauja (Andershed et al, 2002) un Bērnības traumu aptauja (Fink & Bernstein, 1995). Pētījuma rezultātos tika konstatētas saistības starp p…
The Networked Utilisation of Satellite Images and Geospatial Technology in Journalism
2022
Satellite technology has become increasingly affordable and accessible in the past few decades. This has enabled many newsrooms to engage with genuinely remote journalism. This chapter explores the networked nature of satellite journalism and investigates its inclusion of experts and citizens outside newsrooms. Satellite journalism uses satellite-borne technology either as a (1) part of storytelling or (2) source of information. Academic research on the topic is scarce, so this chapter builds a base of knowledge on the contemporary practices, limitations and ethics—as well as directions of future development—of satellite journalism. By interviewing six journalists and one earth observation …

Biochemical and structural analysis of the NS5B RNA-dependent RNA polymerase of the hepatitis C virus.
2000
Hepatitis C virus (HCV), the major causative agent of chronic and sporadic non-A, non-B hepatitis worldwide, is a distinct member of the Flaviviridae virus family. These viruses have in common a plus-strand RNA genome that is replicated in the cytoplasm of the infected cell via minus-strand RNA intermediates. Owing to the lack of reliable cell culture systems and convenient animal models for HCV, the mechanisms governing RNA replication are not known. As a first step towards the development of appropriate in vitro systems, we expressed the NS5B RNA-dependent RNA polymerase (RdRp) in insect cells, purified the protein to near homogeneity and studied its biochemical properties. It is a primer…
H&E Multi-Laboratory Staining Variance Exploration with Machine Learning
2022
In diagnostic histopathology, hematoxylin and eosin (H&E) staining is a critical process that highlights salient histological features. Staining results vary between laboratories regardless of the histopathological task, although the method does not change. This variance can impair the accuracy of algorithms and histopathologists’ time-to-insight. Investigating this variance can help calibrate stain normalization tasks to reverse this negative potential. With machine learning, this study evaluated the staining variance between different laboratories on three tissue types. We received H&E-stained slides from 66 different laboratories. Each slide contained kidney, skin, and colon tissue sampl…
