Type 2 diabetes mellitus (T2DM) and HER2 are associated with cancer although the role of HER2 in T2DM is not well defined. Our aim was to investigate the association between HER2 levels and T2DM and whether that association was different in Swedish people born in Iraq or Sweden.
Background: Patch testing has been used for more than 100 years as the best means to diagnose contact allergy. The increased use of the technique makes standardization of the methodology most important. Progress in the standardization of the patch test technique has been made through guidelines. Objectives: To investigate the intra-individual and inter-individual differences in reading of patch
The process of selecting the right set of requirements for a product release is highly dependent on how well we succeed in prioritising the requirements candidates. There are different techniques available for requirements prioritisation, some more elaborate than others. In order to compare different techniques, a controlled experiment was conducted with the objective of understanding differences
The expansive usage of social media in organisations in recent years has increased research in the field. Due to the nature of social media as a research topic that is studied in diverse contexts, there is an urge for an enacted contemporary literature review to frame the scope of social media in this context. Nowadays social media is on the agenda of many organisations. Many CEOs in their effort
Purpose: To investigate the relative importance of spatial resolution and noise on the image quality of clinical radiographs. Methods: The spatial resolution and noise of fifteen digitised lumbar spine radiographs were altered with image processing. Three different MTF curves and three different Wiener spectra were combined into seven different combinations of spatial resolution and noise. These s
We show that the common claim that internal validity should be understood as prior to external validity has, at least, three epistemologically problematic aspects: experimental artefacts, the implications of causal relations, and how the mechanism is measured. Each aspect demonstrates how important external validity is for the internal validity of the experimental result.
This paper considers how researchers can best establish a forward trajectory in their work, individually and collectively. The suggestion is sometimes made in academic circles that it is inappropriate to present work that revisits an area previously discussed within the field. While we accept that any published paper should make an original contribution to what is collectively known about a partic
The electronic structure of superheavy elements (Z ≥ 104) and their chemical properties are dominated by relativistic effects. Recently two superheavy elements were recognized by the IUPAC and named flerovium (Fl, Z = 114) and livermorium (Lv, Z = 116). Fl is the heaviest element with which chemical experiments were performed. Here, we report on experiments that help answering the long-standing qu
Polycomb ring finger oncogene BMI1 (B cell-specific Moloney murine leukemia virus integration site 1) plays a critical role in development of several types of cancers. Here, we report an inverse relationship between levels of BMI1 expression and adenovirus (Ad) progeny production. Enforced BMI1 expression in A549 cells impaired Ad progeny production. In contrast, knocking-down of endogenous BMI1 e
Questionnaire studies have indicated that patients with dental gold will more frequently have contact allergy to gold. This study aimed at investigating the relationship between contact allergy to gold and the presence and amount of dental gold alloys. A total of 102 patients were referred for patch testing because of suspicion of contact allergy. Patch tests were performed with gold sodium thiosu
