Elinsiirtoliikunnan viikon vapaaehtoisten profiili, motiivit ja aikeet vapaaehtoistyöhön jatkossa

2017

Tutkimuksen tarkoituksena oli kuvailla European Transplant Sport Week (ETSW) -tapahtuman toteuttamista tukevissa vapaaehtoistehtävissä toimineiden vapaaehtoisten profiilia sekä selvittää vapaaehtoisten osallistumisen motiiveja. Lisäksi tutkittiin vapaaehtoisten tietämystä elinsiirron saaneiden liikunnasta ja aikomuksia toimia vapaaehtoisena jatkossa. Tutkimuksessa käsiteltiin vapaaehtoisuutta jälkimodernin yhteiskunnan piirteiden näkökulmasta, jossa refleksiivinen yksilöllisiä tarkoitusperiä tavoitteleva ja episodimaisuuteen perustuva vapaaehtoisuus on syrjäyttämässä aiempaa perinteisiin ja yhteisöllisyyteen tukeutunutta kollektiivista vapaaehtoisuutta. Tutkimus oli kvantitatiivinen tapaust…

Small things matter : of phages and antibiotic resistance conferring plasmids

2016

Viruses and plasmids are small units of genetic material dependent on cells either transiently or continuously. Intriguingly, stories of these small entities intertwine in antibiotic resistance crisis. Horizontal gene transfer enables bacteria to respond rapidly to chances in their environment. Anthropogenic consumption of antibiotics induces the travel of resistance encoding genes mainly as passengers of conjugative plasmids. In this thesis, I demonstrate that clinically important resistance plasmids could evolutionarily rescue susceptible bacteria under lethal antibiotic concentrations. If mobile resistance genes are available in surrounding community, administration of high doses of anti…

The Instability of Ni{N(SiMe3)2}2: A Fifty Year Old Transition Metal Silylamide Mystery

2015

The characterization of the unstable NiII bis(silylamide) Ni{N(SiMe3)2}2 (1), its THF complex Ni{N(SiMe3)2}2(THF) (2), and the stable bis(pyridine) derivative trans-Ni{N(SiMe3)2}2(py)2 (3), is described. Both 1 and 2 decompose at ca. 25 °C to a tetrameric NiI species, [Ni{N(SiMe3)2}]4 (4), also obtainable from LiN(SiMe3)2 and NiCl2(DME). Experimental and computational data indicate that the instability of 1 is likely due to ease of reduction of NiII to NiI and the stabilization of 4 through dispersion forces. peerReviewed

Microencapsulation of Enteric Bacteriophages in a pH-Responsive Solid Oral Dosage Formulation Using a Scalable Membrane Emulsification Process

2019

A scalable low-shear membrane emulsification process was used to produce microencapsulated Escherichia coli-phages in a solid oral dosage form. Uniform pH-responsive composite microparticles (mean size ~100 &micro

The “Seili-index” For The Prediction of Chlorophyll-α Levels In The Archipelago Sea of The Northern Baltic Sea, Southwest Finland

2021

AbstractTo build a forecasting tool for the state of eutrophication in the Archipelago Sea, we fitted a Generalized Additive Mixed Model (GAMM) to marine environmental monitoring data, which were collected over the years 2011–2019 by an automated profiling buoy at the Seili ODAS-station. The resulting “Seili-index” can be used to predict the chlorophyll-α (chl-a) concentration in the seawater a number of days ahead by using the temperature forecast as a covariate. An array of test predictions with two separate models on the 2019 data set showed that the index is adept at predicting the amount of chl-a especially in the upper water layer. The visualization with 10 days of chl-a level predict…

Evaluation of Explosive Strength for Young and Adult Athletes

1988

Abstract The explosive strengths of young (n = 361) and adult (n = 10) male athletes were evaluated by a vertical jumping and a ball-throwing test. The young athletes ranged in age from 10 to 16 years representing seven different sports events: track and field, apparatus gymnastics, basketball, ice hockey, orienteering, skiing, and wrestling. The adult subjects were volleyball players. Weighted vertical counter-movement jumps were performed on a platform connected to an electronic unit which calculated the height of the rise of the body's center of gravity. For the stationary ball throwing test, horizontal throwing velocity was measured for balls of different masses by an electrical apparat…

Social Learning among Transplant Event Volunteers

2019

Volunteering in adapted sports competitions has not been studied as much as in other competitions. Survey data from volunteers in a supportive role at the European Transplant Sport Week 2016 in Finland were analysed to report the way involvement in the event increased knowledge of transplantation. Through social learning theory, the aim of the study was to report the associations between changes in knowledge, training and volunteering experience of supportive role volunteers. A representative sample of the adult volunteers (n=95, Male=35, Female=60; Disabled=31, non-Disabled=64; Mage=49.7y old, SD=16.8) responded to a web-based survey. Questions included self-perceived knowledge of transpla…

Rapid Assessment of COVID-19 Screening Program for Travelers in Iran: A Qualitative Study

2022

AbstractObjective:Coronavirus disease 2019 (COVID-19) screening stations set up by Iranian Red Crescent Society have been available for 17 d with the aim of identifying and treating people with coronavirus, reducing road trips, and sensitizing people to the problem. This study aims to investigate the challenges of the procedure.Methods:A qualitative study was used to find the challenges of the COVID-19 screening centers. Volunteers, branch managers, and headquarter managers of the Iranian Red Crescent Society participated in this study applying snowball sampling. Data were collected by means of in-depth semi-structured telephone interviews in April 2020 after completion of the fever screeni…

Bacteriophage Adherence to Mucus Mediates Preventive Protection against Pathogenic Bacteria

2019

The mucosal surfaces of animals are habitat for microbes, including viruses. Bacteriophages—viruses that infect bacteria—were shown to be able to bind to mucus. This may result in a symbiotic relationship in which phages find bacterial hosts to infect, protecting the mucus-producing animal from bacterial infections in the process. Here, we studied phage binding on mucus and the effect of mucin on phage-bacterium interactions. The significance of our research is in showing that phage adhesion to mucus results in preventive protection against bacterial infections, which will serve as basis for the development of prophylactic phage therapy approaches. Besides, we also reveal that exposure to m…
