Total normothermic venoarterial bypass was established in 6 healthy pigs over a period of 18 hours. A heparin-coated closed extracorporeal system was used and no heparin was administered systemically. During the bypass period the main pulmonary artery was occluded and the heart was maintained in a beating state. All the animals maintained stable hemodynamics and normal blood gases during the entir
About 10% of the patients with neurofibromatosis type 1 (NF1) develop malignant peripheral nerve sheath tumors (MPNSTs), accounting for half of all MPNST cases. Several nonrandom chromosomal aberrations have been found, but the target genes remain mostly unrecognized. Mutations in the NF1 and TP53 genes have been found in some MPNSTs, and recent data from mouse models support a synergistic effect
As part of a systematic palaeohydrological reconstruction of lake level fluctuations during the Last Glacial Maximum, a transect of cores from ancient Lake Xinias in centra Greece has already been studied with respect to pollen, sediment and mineral magnetic analyses. The chronology was based on C-14 AMS dating of terrestrial plant macrofossil remains from peat and clayey peat (Palaeogeog. Palaeoc
To sample information optimally, sensory systems must adapt to the ecological demands of each animal species. These adaptations can occur peripherally, in the anatomical structures of sensory organs and their receptors; and centrally, as higher-order neural processing in the brain. While a rich body of investigations has focused on peripheral adaptations, our understanding is sparse when it comes
Although sexual selection and sexual conflict are important evolutionary forces in animals, their significance in plants is uncertain. In hermaphroditic organisms, such as many plants, sexual conflict may occur both between mating partners (interlocus conflict) and between male and female sex roles within an individual (intralocus conflict). We performed experimental evolution, involving lines tha
We investigated the prevalence of postnatal depressive mood in a national Swedish sample, together with factors associated with depressed mood postpartum only as opposed to having depressed mood both in early pregnancy and postpartum. Swedish-speaking women booked for antenatal care during a chosen period of three recruitment weeks were invited and 3293 (72%) agreed to participate in the study. Of
Methods for detecting depression in fathers after the birth of their child are scarce. The Edinburgh Postnatal Depression Scale (EPDS), used to screen mothers for postpartum depression (PPD), lacks somatization and externalizing items. This potentially decreases its sensitivity in detecting depression in fathers, as many men actually express depression with somatization or externalizing symptoms.
Controlling robots in real-time over a wireless inter- face present fundamental challenges for forthcoming fifth gen- eration wireless networks. Mission critical real-time applications such as telesurgery over the tactile Internet require a commu- nication link that is both ultra-reliable and low-latency, and that simultaneously serving multiple devices and applications. Wireless performance requi
We used a southern Swedish cohort of psoriasis (PSO) and psoriatic arthritis (PsA) patients and population-based referents (N = 57,800) to investigate the influence of socioeconomic and demographic factors on the probability of healthcare use and on healthcare costs when controlling for need as measured by PSO/PsA and common additional morbidities such as diabetes, depression and myocardial infarc
Achieving control of the surface chemistry of colloidal quantum dots (CQDs) is essential to fully exploit their properties in solar cells, but direct measurement of the chemistry and electronic structure in the outermost atomic layers is challenging. Here we probe the surface oxidation and passivation of cation-exchanged PbS/CdS core/shell CQDs with sub nm-scale precision using synchrotron-radiati
Exposure to vibrations from tools and machines used in construction work can induce damages to the human body. One of the most frequent symptoms is the hand-arm vibration syndrome commonly known as white fingers. The proportions of the international workforce exposed to vibrations are high and dominating sectors are construction, agriculture, forestry, and transport. Particularly exposed construct
The literature on economic geography suffers from a lack of attention to the emergence of new industries. Recent literature on "regional branching" proposes that new industries emerge in regions where preexisting economic activities are technologically related to the emerging industry. This article provides a more grounded basis for the emerging literature on regional branching by confronting the
Vibration disturbances in buildings may stem from ambient sources, such as motorway traffic, or from internal sources such as people walking inside the building. Vibrations can exceed requirements for sensitive equipment or cause annoyance to humans and therefore the vibrations may need to be reduced. Vibrations from both external and internal sources can be reduced by modifying the properties of
Disentangling the individual and interactive effects of multiple stressors on microbial communities is a key challenge to our understanding and management of ecosystems. Advances in molecular techniques allow studying microbial communities in situ and with high taxonomic resolution. However, the taxonomic level which provides the best trade-off between our ability to detect multiple-stressor effec
The flame dynamics in a novel, ultra-lean non-premixed model gas turbine (GT) burner flame was numerically studied using large eddy simulation (LES) coupled with probability density function (PDF) based on the Euler stochastic field (ESF) method. One non-reacting case and three reacting cases with global equivalence ratio ϕglob=1.0,0.6,0.3 were simulated. Comparison of mean flow fields and OH dist
Recent developments within sensual and sexy exercise have led to fashionable dance studios and gyms introducing their customers to pole dancing and other forms of sensual exercise. From the aspect of pole dancers being dirty workers the studios who teach pole dancing are now struggling to get away from the negative prejudices of the sport. We have been studying the corporate identity and image in
Skogarna på den norra hemisfären har en betydande roll i den globala kolbalansen på grund av deras förmåga att agera som kolkälla. En annan aspekt som gör de intressanta är deras känslighet för tänkbara kommande klimatförändringar där en möjlig följd är ökad störningsfrekvens. Störningar (som bland annat innefattar storm, insektsangrepp och brand) påverkar skogens kolbalans genom att minska upptagOn the night between the 8th and 9th of January 2005 one of the worst wind storms Sweden has experienced took place. The storm caused damage to 270 000 ha of forest and 75 · 106 m3 wood. Due to the great areas affected, this event has a significant effect on the forest carbon balance. The aim of this study includes determining the usefulness of MODIS (moderate resolution imaging spectroradiometer)
Purpose: The Chinese mining industry is the third biggest in the world in terms of scale and magnitude. Due to the growing importance of the Chinese market, Sandvik Mining and Construction is investing heavily in China. As a result, there is a need for a new marketing plan for China. The marketing efforts will increase much, but since the marketing department has been relatively undeveloped, there
The most important issue in this dissertation will be a discussion concerning metal age flint use in Scania. Since flint tools from the Bronze and Iron Ages and Medieval times have rarely been examined, there are few general guidelines in typology or morphology. It is quite clear that conversions of existing Stone Age typological schemes are unsuitable when one intends to study the often simple an
