Do moor frog (Rana arvalis) and common frog (R. temporaria) tadpoles increase developmental rate if there is a risk of their pond drying up before metamorphosis? To study this, I performed an experiment designed to mimic natural conditions in many drying ponds. The number of tadpoles per tank was constant during the experiment but the water level was lowered in experimental tanks so that crowding

Background: One key aspect of person-centredness is striving to understand both the patients' experiences and behaviours from their perspective. These aspects are precisely those that staff in dementia care highlight as causing them most difficulty because the people in their care have major problems expressing themselves. There is thus a need to develop a method to help the staff to achieve inter

INTRODUCTION: Increasing evidence suggests that optimal food choice is critical for sizable prevention of western diseases such as cardiovascular disease and cancer. The Mediterranean diet is an important step in this direction. Moreover, substantially lower rates of Western disease, even compared to Mediterranean countries, have been observed among hunter-gatherers and other non-western populatio

Models of the engineering design process and of the development process nowadays present similar forms in the engineering design literature and interact in a similar way. These models are often presented as generic, in order to be used in a wide area of applications. This interaction is, however, not unproblematic, and in this publication we present some important issues and challenge the generic

As sentient and social beings, we live in hope that we can be understood when we try to communicate with each other but we also know that we might be wrong. We strive for better understandings, engaging in an on-going ‘dance’ of collective sense-making. This paper considers how communication among individuals involves co-creation of meaning by exploring narratives – those expressed by a speaker an

The relative contribution of transcytosis vs. large pore transport to the passage of macromolecules across microvascular endothelia has been a controversial issue for nearly half a century. To separate transcytosis from 'porous' transport, the transcytosis inhibitors N-ethylmaleimide (NEM) and filipin have been tested in in situ or ex vivo perfused organs with highly conflicting results. In contin

Texture of potatoes with different shapes (slices and strips) were evaluated after frying and in some cases after baking. Blanched and unblanched potato slices (Bintje variety) were fried at four oil temperatures: 160, 170, 180 and 190C until reaching a moisture content of similar to1.7%. A puncture test with three point support for the slices was applied to measure the texture of potato chips usi

Mouse mammary tumor virus (MMTV)-like sequences have been found in up to 40% of breast cancer samples but in <2% of normal breast tissue samples from Australian women studied by our group. Screening of a larger and more diverse cohort of female breast cancer samples has now shown a correlation of MMTV-like sequences with the severity (grade) of breast cancer. Thirty-two percent (43 of 136) of fema

Purpose – The purpose is to describe the advantages, challenges and uncertainties of collecting and analyzing data using participant observation in logistics research. Design/methodology/approach – Experiences from a participant observation study of an interorganizational RFID implementation in an international environment are presented and reflected on. The RFID implementation included complex in

Objective: To examine the possible relationships of breast cancer risk to prediagnostic plasma levels of insulin; insulin-like growth factor-I (IGF-I); and IGF-binding proteins -1, -2, and -3. Methods: Within two prospective cohorts in Umea and Malmo we measured plasma concentrations of insulin, IGF-I, and IGFBPs for a total of 513 incident breast cancer cases and 987 matched controls. Results: Gl

Preference studies of many different collembolan species have categorised collembolans being selective in their food choice. To clarify whether collembolan food selectivity is related to fitness parameters, three species, Folsomia fimetaria, Protaphorura armata and Heteromurus nitidus, were fed three fungal species, Alternaria infectoria, Mucor hiemalis and Penicillium hordei, representing fungi o

During forward flight, a bird's body generates drag that tends to decelerate its speed. By flapping its wings, or by converting potential energy into work if gliding, the bird produces both lift and thrust to balance the pull of gravity and drag. In flight mechanics, a dimensionless number, the body drag coefficient (C-D,C-par), describes the magnitude of the drag caused by the body. The drag coef

The purpose of this study was to investigate illness experiences of patients after a first myocardial infarction (MI), focusing on life situation and the recovery process over time. Thirty patients were interviewed within the first 3 days of hospitalisation, and again 17 weeks after discharge. The interviews were tape-recorded verbatim and the transcriptions were analysed and categorised using qua

Introduction and objective Misreporting fractures in questionnaires is known. However, the effect of misreporting on the association of fractures with subsequent health outcomes has not been examined. Methods Data from a fracture registry (FR) developed from an extensive review of radiographic and medical records were related to self-report of fracture for 2,255 participants from the AGES Reykjavi

BACKGROUND: Vasopressin is widely used for vasopressor support in septic shock patients, but experimental evidence suggests that selective V1A agonists are superior. The initial pharmacodynamic effects, pharmacokinetics, and safety of selepressin, a novel V1A-selective vasopressin analogue, was examined in a phase IIa trial in septic shock patients.METHODS: This was a randomized, double-blind, pla

In men from the general population, BMI has been associated with a lower sperm DNA fragmentation index (DFI). We wondered whether this could be due to estradiol, which is associated with BMI and reported important for sperm function. Our objective was to investigate the association between estradiol and DFI. In 2008–2010, we recruited 284 young men from the general population to deliver samples of

Just like other complex biological features, image vision (multi-pixel light sensing) did not evolve suddenly. Animal visual systems have a long prehistory of non-imaging light sensitivity. The first spatial vision was likely very crude with only few pixels, and evolved to improve orientation behaviors previously supported by single-channel directional photoreception. The origin of image vision wa

Persons who move into dementia care homes may experience a range of threats to their identity and sense of self. To counteract this depersonalisation, dementia care homes in many parts of the world have incorporated the use of life stories.In Nordic eldercare policy, the bare existence of life stories has been used as quality indicators when rating dementia care homes. However, in contrast to othe
