Overexpression and functional characterization of kinin receptors reveal subtype-specific phosphorylation.
1999
G protein-coupled receptors such as the receptors for bradykinin are present in low copy numbers in most natural cells. To overcome the problems associated with the analysis of these receptors at the protein level, we used highly efficient expression systems such as the baculovirus/insect cell system. However, the structural and functional statuses of recombinant receptors have often remained elusive. We have expressed the two types of human kinin receptors, B1 and B2, in Sf9 cells. Both receptors are found on the surface of infected cells where they display the same pharmacological profiles as their cognate receptors of native cells. The functional analysis of kinin receptors coupled to th…
Different genomic organization and expression of immunoglobulin light-chain isotypes in the rainbow trout.
2000
cDNA studies have distinguished two isotypes of the rainbow trout (Oncorhynchus mykiss) immunoglobulin (Ig) light chain (designated L1 and L2). This study characterized genomic clones of these isotypes. L1 genes are arranged in clusters with single copies of variable (V), joining (J), and constant (C) segments. The transcriptional orientation of the V genes is opposite to that of the J and C segments, indicating that the V genes must be rearranged by inversion. L2 is also organized in clusters, consisting of two or three V, one J, and one C exon, all in the same transcriptional orientation. L1 and L2 of rainbow trout are similar to the previously identified cod and catfish clusters. Repeat …
Privacy preserving data collection for smart grid using self-organizing map
2017
Homomorphic encryption is widely researched in the smart grid area to publish and transfer electricity consumption data between electricity companies. This method makes it feasible to calculate total electricity consumption of neighborhoods without sharing any raw electricity consumption data. In the area of demand response(DR), calculating the total consumption of electricity is important in order to create DR reports which are published by third party to reduce the peak period of electricity usage such as 7 am or 6pm. Nevertheless, the possibility of data exposing or data decryption may lead to individual households private information revealing, for example, the timing of leaving home, t…
Relationship between lower limb neuromuscular performance and bone strength in postmenopausal women with mild knee osteoarthritis.
2014
Objectives: To investigate whether neuromuscular performance predicts lower limb bone strength in different lower limb sites in postmenopausal women with mild knee osteoarthritis (OA). Methods: Neuromuscular performance of 139 volunteer women aged 50-68 with mild knee OA was measured using maximal counter movement jump test, isometric knee flexion and extension force and figure-of-eight-running test. Femoral neck section modulus (Z, mm³) was determined by data obtained from dualenergy X-ray absorptiometry. Data obtained using peripheral quantitative computed tomography was used to asses distal tibia compressive (BSId, g2/cm4) and tibial mid-shaft bending (SSImaxmid, mm3) strength indices. R…
CH4 oxidation in a boreal lake during the development of hypolimnetic hypoxia
2020
AbstractFreshwater ecosystems represent a significant natural source of methane (CH4). CH4 produced through anaerobic decomposition of organic matter (OM) in lake sediment and water column can be either oxidized to carbon dioxide (CO2) by methanotrophic microbes or emitted to the atmosphere. While the role of CH4 oxidation as a CH4 sink is widely accepted, neither the magnitude nor the drivers behind CH4 oxidation are well constrained. In this study, we aimed to gain more specific insight into CH4 oxidation in the water column of a seasonally stratified, typical boreal lake, particularly under hypoxic conditions. We used 13CH4 incubations to determine the active CH4 oxidation sites and the …
Arbuscular mycorrhizal fungi influence host infection during epidemics in a wild plant pathosystem
2022
SummaryWhile pathogenic and mutualistic microbes are ubiquitous across ecosystems and often co-occur within hosts, how they interact to determine patterns of disease in genetically diverse wild populations is unknown.To test whether microbial mutualists provide protection against pathogens, and whether this varies among host genotypes, we conducted a field experiment in three naturally-occurring epidemics of a fungal pathogen, Podosphaera plantaginis, infecting a host plant, Plantago lanceolata, in the Åland Islands, Finland. In each population, we collected epidemiological data on experimental plants from six allopatric populations that had been inoculated with a mixture of mutualistic arb…
Growth form matters – Crustose lichens on dead wood are sensitive to forest management
2022
Lichens have a vital role in forest ecosystems and they are a threatened group in boreal forests. However, the conservation ecology of the total lichen community has very rarely been studied. Here we studied lichen species and communities, including macrolichens (=foliose and fruticose growth forms) and rarely studied crustose li-chens, on decaying wood in boreal spruce-dominated forests in Finland. We also studied obligate lignicoles that grow only on dead wood and are mostly crustose in growth form. Species richness and community composition were examined on decaying logs and natural or cut stumps of Picea abies at different decay stages (2-5) in 14 stands, half of which were natural or s…
Tutkimusmatka pienyrittäjän työvalmiuksien ytimeen : kirjallisuuteen ja DACUM-analyysiin perustuva kartoitus
2007
This study examines the occupational competence and attitudes that small business entrepreneurs consider essential to their work. Small business entrepreneurs were given an opportunity to express their views in small focus groups of peer entrepreneurs. Consensus opinions formulated by the groups were then meticulously documented. The results expose the very core or soul of entrepreneurial competence and attitudes by determining what small business entrepreneurs feel they must be able to do. Acknowledgement and acceptance of tacit knowledge as part of one's competence and attitudes would introduce a systematic approach to the recording of such knowledge and enable its transfer to co-workers …
Mykoob un eKool sistēmu biznesa procesu analīze un iespējamās integrētās sistēmas piedāvājuma izveide
2019
Mūsdienās tiek paplašinātas un parādās aizvien jaunas informācijas sistēmas ar līdzīgām funkcionalitātēm. Katras šīs sistēmas izstrādei, uzturēšanai un papildināšanai tiek ieguldīts milzīgs apjoms darba un līdzekļu. Sistēmu integrācija ilgtermiņā samazinātu nepieciešamos resursus. Sistēmu biznesa procesu atpazīšana, pārvaldīšana, optimizācija un integrācija varētu būt ieguldījums un soli ceļā uz sistēmu integrāciju. Darba mērķis ir elektroniskajās skolu sistēmās Mykoob un eKool atrast svarīgākos biznesa procesus, to aprakstīt, salīdzināt un piedāvāt integrētā procesa variantu. Darbā tiek vispārīgi aprakstīta teorija par biznesa procesiem, to nozīmi un iegūšanu izveidotās sistēmās. Darba uzd…
