The Bluethroat subspecies Cyanecula svecica svecia occurs throughout the northern Palearctic. European C. s. svecia has been shown to follow a route west of the Himalaya to winter quarters in southern Asia. Out of 30 Bluethroats tagged with geolocators in eastern Siberia, we obtained one track suggesting that it migrated east of the Himalaya to a wintering area located in Myanmar. The different ro
Birds occupy habitats ranging from Antarctic ice shelves and Arctic tundra to low-latitude deserts and lowland rainforests, and so are exposed to the full range of climates present on Earth. Cold, hot, or variable (on a variety of temporal scales) thermal conditions can present significant thermoregulatory challenges to birds, which typically must maintain body temperatures within narrow physiolog
BACKGROUND: Limited data are available on the incidence of mechanical complications after ultrasound-guided central venous catheterisation. We aimed to determine the incidence of mechanical complications in hospitals where real-time ultrasound guidance is clinical practice for central venous access and to identify variables associated with mechanical complications.METHODS: All central venous cathe
Background: The global prevalence of chronic obstructive pulmonary disease (COPD) has increased markedly in recent decades. Given the scarcity of resources available to address global health challenges and respiratory medicine being relatively under-invested in, it is important to define research priorities for COPD globally. In this paper, we aim to identify a ranked set of COPD research prioriti
The objective of this study is to increase the knowledge regarding school principals’work situations by examining the associations between various factors and the school principals’assessments of their ability or wish to work until 65 years of age or longer. The 1356 participatingschool principals in this study were aged between 50 and 64 years of age. Individual and workfactors were evaluated in
Hamilton’s rule provides the cornerstone for our understanding of the evolution of all forms of social behavior, from altruism to spite, across all organisms, from viruses to humans. In contrast to the standard prediction from Hamilton’s rule, recent studies have suggested that altruistic helping can be favored even if it does not benefit relatives, as long as it decreases the environmentally indu
Recent studies have shown increased concentration of fetal hemoglobin (HbF) in pre-eclamptic women. Plasma hemopexin (Hpx) and alpha-1-microglobulin (A1M) are hemoglobin scavenger proteins that protect against toxic effects of free heme released in the hemoglobin degradation process. We used an enzyme-linked immunosorbent assay to analyze maternal plasma Hpx and A1M concentrations at 12–14, 18–20
Chemical processing by plasma is utilized in many applications. Plasma-related studies, however, are challenging to carry out due to plasmas' transient and unpredictable behavior, excessive luminosity emission, 3D complexity and aggressive chemistry and physiochemical interactions that are easily affected by external probing. Laser-induced fluorescence is a robust technique for non-intrusive inves
Objective: To compare the rate of vaginal birth after cesarean section (VBAC), including the maternal and perinatal outcomes, in two historical cohorts before and after the implementation of specific changes in the clinical practice. Design: A retrospective cohort study. Setting: Skåne University Hospital in Malmö, Sweden. Participants: including all women with one previous cesarean section (CS),
Persons with stress-related disorders, mental disorders and neuropsychiatric disabilities are in particular vulnerable to cognitive challenges at the workplace. The barriers faced by persons with communicative, social and cognitive disabilities are most often invisible to persons in the environment. The objective of the study presented in this paper is to develop and test a tool that increases awa
Teacher education for upper secondary school in Sweden is mainly university-based but with parts of the studies as school-based courses. To tackle the main obstacles to pre-service teachers’ placements, and to strengthen collaboration regarding quality and collaborative research, a new national policy is being implemented, which changes the prerequisites for collaboration between schools and unive
Insects rely on path integration (vector-based navigation) and landmark guidance to perform sophisticated navigational feats, rivaling those seen in mammals. Bees in particular exhibit complex navigation behaviors including creating optimal routes and novel shortcuts between locations, an ability historically indicative of the presence of a cognitive map. A mammalian cognitive map has been widely
In this paper we present a novel method for predictive coding with application to transmission of speech over packet-switched networks. Our method uses multiplexing to distribute a part of the information about a segment of each speech signal in several data packets while keeping the data packet rate and payload for that part of the information unchanged. We investigate three multiplexing schemes:
Galectin-3 is extensively involved in metabolic and disease processes, such as cancer metastasis, thus giving impetus for the design of specific inhibitors targeting this -galactose-binding protein. Thiodigalactoside (TDG) presents a scaffold for construction of galectin inhibitors, and its inhibition of galectin-1 has already demonstrated beneficial effects as an adjuvant with vaccine immunothera
The objective of this study was to identify possible changes in mRNA and protein expression of high-mobility group box protein 1 (HMGB1) and its suggested receptors - receptor for advanced glycation end-products (RAGE) and Toll-like receptor 2 (TLR2) and TLR4 - in human cervix during pregnancy, term and preterm labor. Cervical biopsies were taken from 58 women: 20 at preterm labor, 24 at term labo
