With the full-scale colonization of Hokkaido, home to the indigenous Ainu people, by the Japanese Meiji government (1868-1912), unprecedented ethnographic opportunities emerged for Western scientists and adventure-seekers. Literally dozens of such individuals “discovered” information about the Ainu and their homeland during this period, introducing European and American audiences to the subject th

BACKGROUND: Caveolin-1 (CAV1) is associated with cholesterol-rich membrane raft domains and is a master regulator of cell signaling and membrane transport. Here, we investigated CAV1's role in cellular compartments of breast cancer in relation to signaling pathways, clinicopathological features, and clinical outcomes.METHODS: CAV1 levels were evaluated with immunohistochemistry in cytoplasm of inv

The energy sector is in urgent need for carbon-free strategies considering environmental pollutions and climate change impact. Two kinds of solid fuels, biomass and metal particles have been studied in this thesis aiming at CO2 emission reduction or zero carbon emission. Biomass is a renewable and carbon-neutral energy source that provides heat and power through gasification and combustion. Biomas

In this single-center cohort study, we applied a panel of laboratory markers to characterize hemostatic function in 217 consecutive patients that underwent testing for COVID-19 as they were admitted to Linköping University Hospital between April and June 2020. In the 96 patients that tested positive for SARS-CoV-2 (COVID-19+), the cumulative incidences of death and venous thromboembolism were 24.0

Activated partial thromboplastin time (APTT) is widely practiced in preoperative screening. The value of using this test to predict the risk of perioperative bleeding is not well documented in Sweden. In this article, a literature review is performed to determine whether unselected APTT testing can predict abnormal perioperative bleeding. The current literature does not support coagulation screeni

In laboratory medicine, much effort has been put into analytical quality in the past decades, making this medical profession one of the most standardized with the lowest rates of error. However, even the best analytical quality cannot compensate for errors or low quality in the pre or postanalytical phase of the total testing process. Guidelines for data reporting focus solely on defined data elem

In patients with suspected venous thromboembolism (VTE), it is recommended to estimate the pre-test probability of VTE, either by experience or by standardized scoring schemes (e.g. Wells or Geneva score), before performing a D-dimer test [1], [2]. Patients with a low probability or unlikely VTE should have D-dimer performed, and if negative, VTE can be excluded, without further investigations, wh

Der findes flere trombotiske mikroangiopatier, som kan væresvære at adskille ud fra den kliniske præsentation. Mangel på etnyopdaget enzym, a disintegrin and metalloprotease with throm-bospondin type 1 motifs (ADAMTS)-13, kan forårsage trombotisktrombocytopenisk purpura (TTP). Mangel på ADAMTS-13 fører tiløgede koncentrationer af højmolekylære von Willebrand-faktor-former i plasma og fremmer danneThrombotic microangiopathy can be caused by several conditions which are difficult to diagnose from the clinical presentation alone. Deficient enzyme activity of a newly-discovered enzyme, ADAMTS-13, can lead to thrombotic thrombocytopenic purpura (TTP). Lack of ADAMTS-13 activity causes increased concentrations of high molecular weight von Willebrand factor forms and increased platelet aggregatio

Dabigatran is an oral, reversible thrombin inhibitor that has shown promising results in large clinical trials. Laboratory monitoring is not needed but the effects on common coagulation assays are incompletely known. Dabigatran was added to plasma from healthy subjects in the concentration range 0-1,000 μg/l and analysed using several reagents for activated thromboplastin time (APTT), prothrombin

Flerovium (Fl, element 114) is the heaviest element chemically studied so far. To date, its interaction with gold was investigated in two gas-solid chromatography experiments, which reported two different types of interaction, however, each based on the level of a few registered atoms only. Whereas noble-gas-like properties were suggested from the first experiment, the second one pointed at a vola

The need is great for a simple, cheap and readily accessible method for the evaluation of primary hemostasis in work-ups at both out-patient clinics and units caring for surgical or intensive care patients. PFA-100 is a recently introduced instrument for in vitro testing of platelet function. We report experiences from Stockholm, Gothenburg and Malmo of PFA-100 measurements performed on samples fr
