Amputation for occusive arterial disease - A prospective multicentre study of 177 amputees

All major amputations of the lower limb due to occlusive arterial disease were studied prospectively and consecutively during one year in the 5 hospitals in Malmöhus county, Sweden. The patients were followed for 6 months after the primary amputation of which 136 were through the tibia, 6 through the knee and 35 through the femur. One hundred and seventy-seven patients (92 men and 85 women) were i

Localization of the chromosomal breakpoints of the t(12;16) in liposarcoma to subbands 12q13.3 and 16p11.2

Short-term cultures of two myxoid liposarcomas and two mixed-type (myxoid and round cell) liposarcomas were cytogenetically analyzed. A t(12;16)(q13;p11) was present in three tumors, whereas the fourth had an unbalanced 12;16-translocation with breaks in 12q13 and 12q22, with loss of the 12q13-q22 segment, and in 16p11. In the two mixed liposarcomas, the breakpoints could be determined at subband

Characteristic karyotypic anomalies identify subtypes of malignant fibrous histiocytoma

Cytogenetic analysis of short‐term cultures from 25 malignant fibrous histiocytomas (MFH) revealed clonal chromosome abnormalities in 17 tumors: ten storiform‐pleomorphic and seven myxoid MFH. Telomeric associations, rings, and dicentric chromosomes were present in 11 tumors and cytogenetic signs of gene amplification (homogeneously staining regions and double minute chromosomes) in four. The brea

Shifting Priorities in Degrowth Research: An Argument for the Centrality of Human Needs

We present an argument for the deprioritization of subjective well-being and a prioritization of human needs within degrowth research. First, we discuss empirical evidence, methodological problems and theoretical shortcomings of subjective well-being concepts. While data for one country over time suggest a flattening of the happiness curve relative to GDP growth, cross country comparisons reveal t

Amplifying mitochondrial function rescues adult neurogenesis in a mouse model of Alzheimer's disease

Adult hippocampal neurogenesis is strongly impaired in Alzheimer's disease (AD). In several mouse models of AD, it was shown that adult-born neurons exhibit reduced survival and altered synaptic integration due to a severe lack of dendritic spines. In the present work, using the APPxPS1 mouse model of AD, we reveal that this reduced number of spines is concomitant of a marked deficit in their neur

Climate Change, Sustainable Welfare and the State

Comparative empirical studies of the link between economic growth, carbon emissions and ecological footprints (e.g. Fritz and Koch 2016) suggest that current Western production and consumption patterns and welfare standards are incompatible with environmental limits and IPCC climate targets. In the absence of evidence for absolute decoupling of economic growth, material resource input and carbon e

The State in the Transformation to Sustainability in a Postgrowth Context

One of the conclusions from comparative empirical studies of the structural challenges towards making global production and consumption patterns compatible with environmental limits is that rich countries would need to ‘degrow’ (O’Neill 2015; Fritz and Koch 2016). To shed light on the potential role of the state in such a planned downscaling process the paper compares state roles in a capitalist e

Beamline test of a transition-edge-sensor spectrometer in preparation for kaonic-atom measurements

We are developing a new technique to apply transition-edge sensors (TESs) to X-ray spectroscopy of exotic atoms, especially of kaonic atoms. To demonstrate the feasibility of this pioneering project, performance of a TES-based X-ray detector was evaluated in pion- and kaon-beam environments at particle accelerators.We successfully observed X-rays from pionic-carbon atoms with a resolution as good

Swelling and mass transport properties of nanocellulose-HPMC composite films

Composite films were sprayed from mixtures of water soluble hydroxypropyl methylcellulose (HPMC) and either nanofibrillated cellulose (NFC) or cellulose nanocrystals (CNC). Fiber diameter was similar for both nanocelluloses but fiber length was several μm for NFC and about 200 nm for CNC. Films were characterized for morphology, swelling, mass loss and transport properties. NFC-HPMC films swelled

Eosinophils are key regulators of perivascular adipose tissue and vascular functionality

Obesity impairs the relaxant capacity of adipose tissue surrounding the vasculature (PVAT) and has been implicated in resultant obesity-related hypertension and impaired glucose intolerance. Resident immune cells are thought to regulate adipocyte activity. We investigated the role of eosinophils in mediating normal PVAT function. Healthy PVAT elicits an anti-contractile effect, which was lost in m

Identification of the ligand of Pru p 3, a peach LTP

Key message: Pru p 3, a peach LTP, is located in pollinated flower styles and secreting downy hairs, transporting a derivative of camptothecin bound to phytosphingosine. Pru p 3 may inhibit a second pollination and may keep away herbivores until seed maturation. Abstract: The allergen Pru p 3, a peach lipid transfer protein, has been well studied. However, its physiological function remains to be

Evaluation of direct membrane filtration and direct forward osmosis as concepts for compact and energy-positive municipal wastewater treatment

Municipal wastewater treatment commonly involves mechanical, biological and chemical treatment steps to protect humans and the environment from adverse effects. Membrane technology has gained increasing attention as an alternative to conventional wastewater treatment due to increased urbanization. Among the available membrane technologies, microfiltration (MF) and forward osmosis (FO) have been se

Pre-plaque conformational changes in Alzheimer's disease-linked Aβ and APP

Reducing levels of the aggregation-prone Aβ peptide that accumulates in the brain with Alzheimer's disease (AD) has been a major target of experimental therapies. An alternative approach may be to stabilize the physiological conformation of Aβ. To date, the physiological state of Aβ in brain remains unclear, since the available methods used to process brain tissue for determination of Aβ aggregate

Potent pro-inflammatory and profibrotic molecules, osteopontin and galectin-3, are not major disease modulators of laminin α2 chaindeficient muscular dystrophy

A large number of human diseases are caused by chronic tissue injury with fibrosis potentially leading to organ failure. There is a need for more effective anti-fibrotic therapies. Congenital muscular dystrophy type 1A (MDC1A) is a devastating form of muscular dystrophy caused by laminin α2 chaindeficiency. It is characterized with early inflammation and build-up of fibrotic lesions, both in patie

Symbiosis revisited : Phosphorus and acid buffering stimulate N2 fixation but not Sphagnum growth

In pristine Sphagnum-dominated peatlands, (di)nitrogen (N2) fixing (diazotrophic) microbial communities associated with Sphagnum mosses contribute substantially to the total nitrogen input, increasing carbon sequestration. The rates of symbiotic nitrogen fixation reported for Sphagnum peatlands, are, however, highly variable, and experimental work on regulating factors that can mechanistically exp

Kompetensportfölj för dokumentation, reflektion och progression

Vad är en kompetensportfölj? En samling arbetsprover som visar upp den egna kompetensen? En elektronisk plattform för dokumentlagring? En övning i reflektion och utveckling? I denna rapport samlas erfarenheter från medarbetare vid Lunds universitet som under perioden 2015–2016 har arbetat med kompetensportföljer – för studenter och lärare. Rapporten redovisar resultat från tre delprojekt: • Utveck

Stroke recovery activity-dependent mechanisms

Stroke is the leading cause of disability in developed countries and among the major causes of death worldwide. During a stroke, neurons deprived of their normal metabolic substrates cease to function in seconds and show signs of structural damage after only a few minutes which result in the impairment of sensory and motor function. Loss of function after stroke is due to neuronal death and irreve
