Optimized culture conditions for tissue explants of uterine leiomyoma
2012
Background Uterine leiomyomas are the most common benign tumours in women, which arise from smooth muscle cells of the uterine myometrium and usually are multicentric. In spite of their frequency pathogenesis is widely unknown, mainly due to the absence of a suitable model system. We describe the systematic optimization of culturing leiomyoma tissue explants in an economical and effective ex vivo system. Methods Different concentrations of oxygen, different media, sera, hormones, and growth factor supplements were tested. Immunohistochemical stainings with antibodies against hormone receptors as well as specifying proliferation and apoptotic indices and real-time PCR were performed. Results…
Concept of an extracellular regulation of muscular metabolic rate during heavy exercise in humans by psychophysiological feedback.
1996
Efferent motor signals to skeletal muscles concern not only the space/ time pattern of motion, but also the setting of muscular performance and through this the control of the current metabolic rate. For an optimal adjustment of metabolic rate during heavy exercise-e.g. in athletic competitions-a feedback control system must exist, including a programmer that takes into consideration a finishing point (teleoanticipation). The presented experiments, using Borg's scale, indicate the existence and functioning of a system for optimal adjustment of performance during heavy exercise and the relevance of teleoanticipatory effects. Thus motor learning includes not only somatosensory control, but al…
Mobile diary for wellness management--results on usage and usability in two user studies.
2008
The prevalence of lifestyle-related health problems is increasing rapidly. Many of the diseases and health risks could be prevented or alleviated by making changes toward healthier lifestyles. We have developed the Wellness Diary (WD), a concept for personal and mobile wellness management based on Cognitive-Behavioral Therapy (CBT). Two implementations of the concept were made for the Symbian Series 60 (S60) mobile phone platform, and their usability, usage, and acceptance were studied in two 3-month user studies. Study I was related to weight management and study II to general wellness management. In both the studies, the concept and its implementations were well accepted and considered as…
Differential regulation of hexameric and dodecameric hemocyanin from A. leptodactylus
2013
The oxygen binding properties of hemocyanins are regulated on a short time scale by effectors such as l-lactate, urate and protons, and on longer time scales by expression of the different types of subunits. For Astacus leptodactylus it was shown previously that acclimation to higher temperatures leads to increased levels of a 6-meric hemocyanin species, whereas at lower temperatures the 12-meric form prevails. Here we show that the temperature dependence of the two forms supports the idea, that the maintenance of high affinity towards oxygen is the driving force for the differential expression of these hemocyanins. Furthermore, the two different types of hemocyanin differ not only in the a…
Käsitteellinen ymmärtäminen ja fysiikan oppimiseen liittyvät odotukset lukion mekaniikassa
2018
Aikaisempi tutkimus (Utriainen 2004) ja myöhempi oppimistulosten tarkastelu paljastivat puutteita, jotka koskivat kappaleen liiketilan ja kappaleen vuorovaikutusten välisen yhteyden ymmärrystä. Voimakuvion laadinta ja liikeyhtälön kirjoittaminen tuottivat vaikeuksia. Pakollisella fysiikan kurssilla opiskelijat muodostavat käsityksen, joka koskee fysiikkaa oppiaineena ja sen opiskelua. Saaduilla kokemuksilla voi olla merkitystä fysiikan syventäviin kursseihin kohdistuviin odotuksiin. Opetukselle asetettiin kaksi tavoitetta: piti edistää Newtonin toiseen ja Newtonin kolmanteen lakiin liittyvien tehtävien kvalitatiivista osaamista ja liikeyhtälön kirjoittamista sekä yrittää vaikuttaa opiskelij…

Assessment of Cyber Security risks : A Smart Terminal Process
2023
In Finland, the connections to global maritime transportation logistics systems are an essential part of the national critical infrastructure. As a part of maritime logistics systems, the port's operations are important elements for global maritime traffic and the transportation supply chain. Digitalization of seaport services makes it possible to increase the efficiency of terminal systems in the logistic processes. At the same time, port logistic processes can notably reduce its CO2 emissions by optimizing port operations. The improvement of port processes relies very much on the development of Information and Communication Technology (ICT) and Industrial Control Systems (ICS) or Operatio…
