Luomutuotteiden ostamiseen vaikuttavat tekijät: Case Lappeenrannan K-citymarket

Tutkimuksen tavoite oli selvittää sitä ristiriitaa, joka vallitsee kuluttajien ilmoittaman ja todellisen luomutuotteiden ostokäyttäytymisen välillä. Tätä ristiriitaa tutkittiin selvittämällä ostoprosessin eri osia ja niihin vaikuttavia tekijöitä, kuten sitoutumisastetta, arvoja ja asenteita. Tutkimusmenetelmänä käytettiin kyselytutkimusta, jonka aineisto kerättiin kontrolloidulla kyselyllä yhden viikon aikana Lappeenrannan K-citymarketissa.Tulokset osoittivat, että kuluttajat ostavat luomutuotteita, jos ne koetaan omaa itseä hyödyttäviksi, eli tärkeimmät ostamisen syyt olivat hyvä maku, lisäaineettomuus ja terveellisyys. Sen sijaan kollektiivinen etu, kuten ympäristöystävällisyys, ei ollut kovinkaan tärkeä luomunostoperuste. Näyttäisi myös siltä, että ne, jotka arvo- ja ajatusmaailmansa puolesta olisivat potentiaalisia luomutuotteiden kuluttajia, ostavat muita tuotteita tottumuksen perusteella.

Alterations of Na, K and Rb concentrations in Mycenaean pottery and a proposed explanation using X-ray diffraction

One of the most important reference groups for Mycenaean pottery is the Mycenae/Berbati (MB). In several studies, a second group has been identified (MBKR). The chemical compositions were similar to MB, but with important differences in the Na, K and Rb contents. The present study suggests that these differences are due to selective alteration and contamination processes that are indirectly determined by the original firing temperature. Therefore, groups MB and MBKR should be considered as a single reference group.

Theoretical modeling of photon and electron-stimulated Na and K desorption from SiO2

The mechanism of generation of atomic Na and K from SiO2 samples has been studied using explicitly correlated wave function and density functional theory cluster calculations. Possible pathways for the photon and electron stimulated desorption of Na and K atoms from silicates are proposed, thus providing new insight on the generation of the tenuous Na and K atmosphere of the Moon.

Increased voltage-dependent K+ channel Kv1.3 and Kv1.5 expression correlates with leiomyosarcoma aggressiveness

Voltage-dependent K+ channels (Kv) are involved in the proliferation and differentiation of mammalian cells, since Kv antagonists impair cell cycle progression. Although myofibers are terminally differentiated, some myoblasts may re-enter the cell cycle and proliferate. Since Kv1.3 and Kv1.5 expression is remodeled during tumorigenesis and is involved in smooth muscle proliferation, the purpose of this study was to analyze the expression of Kv1.3 and Kv1.5 in smooth muscle neoplasms. In the present study, we examined human samples of smooth muscle tumors together with healthy speci­mens. Thus, leiomyoma (LM) and leiomyosarcoma (LMS) tumors were analyzed. Results showed that Kv1.3 was poorly expressed in the healthy muscle and indolent LM specimens, whereas aggressive LMS showed high levels of Kv1.3 expression. Kv1.5 staining was correlated with malignancy. The findings show a remodeling of Kv1.3 and Kv1.5 in human smooth muscle sarcoma. A correlation of Kv1.3 and Kv1.5 expression with tumor aggressiveness was observed. Thus, our results indicate Kv1.5 and Kv1.3 as potential tumorigenic targets for aggressive human LMS.

Updates in the perioperative and emergency management of non-vitamin K antagonist oral anticoagulants.

Perioperative management of patients treated with the non-vitamin K antagonist oral anticoagulants is an ongoing challenge. Due to the lack of good clinical studies involving adequate monitoring and reversal therapies, management requires knowledge and understanding of pharmacokinetics, renal function, drug interactions, and evaluation of the surgical bleeding risk. Consideration of the benefit of reversal of anticoagulation is important and, for some low risk bleeding procedures, it may be in the patient's interest to continue anticoagulation. In case of major intra-operative bleeding in patients likely to have therapeutic or supra-therapeutic levels of anticoagulation, specific reversal agents/antidotes would be of value but are currently lacking. As a consequence, a multimodal approach should be taken which includes the administration of 25 to 50 U/kg 4-factor prothrombin complex concentrates or 30 to 50 U/kg activated prothrombin complex concentrate (FEIBA®) in some life-threatening situations. Finally, further studies are needed to clarify the ideal therapeutic intervention.
