Genetic characterization of amyloid-β and tau network spread

Protein-specific and shared genetic pathways influence the spread of amyloid-β and tau pathology. Hence, distinct gene expression profiles may induce regional vulnerability of the human cortex to the specific proteinopathies of Alzheimer’s disease.

Αν και η αρχαία ελληνική αποτελούσε βασικό μάθημα στο Πανεπιστήμιο Lund από την αρχή της λειτουργίας του, η διδασκαλία της Νέας Ελληνικής ξεκίνησε το 1957 υπό την επίδραση του αυξανόμενου ενδιαφέροντος για τη νεοελληνική λογοτεχνία και της ανάγκης εκπαίδευσης των Σουηδών αρχαιολόγων με αντικείμενο έρευνας την Ελλάδα. Το Τμήμα Νεοελληνικών Σπουδών του Πανεπιστημίου Lund, έχοντας πλέον αυτονομηθεί α

Heart filling exceeds emptying during late ventricular systole in patients with systolic heart failure and healthy subjects – a cardiac MRI study

Background: Total heart volume (THV) within the pericardium is not constant throughout the cardiac cycle and THV would intuitively be lowest at end systole. We have, however, observed a phase shift between ventricular outflow and atrial inflow which causes the minimum THV to occur before end systole. The aims were to explain the mechanism of the late-systolic net inflow to the heart and determine

Removal of UHT dairy fouling — An efficient cleaning process by optimizing the rate controlling alkaline cleaning step

A rigid mineral-based deposit, termed ultra-high temperature (UHT) fouling, is formed on heat exchanger surfaces during milk processing at 140 °C. The removal of this type of fouling is for the first time assessed using a laser triangulation sensor and a camera, to measure changes in the thickness and to visualize structural changes in the fouling in situ. The process was monitored during both the

High-density and targeted glycoproteomic profiling of serum proteins in pancreatic cancer and intraductal papillary mucinous neoplasm

Objective: Glycoproteomics is an emerging subfield of proteomics. Tumor-specific variations in protein glycosylation might be potential targets for the development of new cancer diagnostics. Here, we performed high-throughput screening and targeted verification of glycome alterations in serum samples from patients with pancreatic cancer and the precancerous lesion intraductal papillary mucinous ne

Cost effectiveness of implementing ESC guidelines for treatment of iron deficiency in heart failure in the Nordic countries

Objectives. Guidelines of the European Society of Cardiology (ESC) recommend that ferritin and transferrin saturation should be tested in chronic heart failure (HF) and state that iron treatment with ferric carboxymaltose should be considered in HF patients with iron deficiency to alleviate symptoms and improve exercise tolerance and quality of life. This study evaluates the cost effectiveness of

Physicochemical and structural properties of starch from five Andean crops grown in Bolivia

Three Andean grains - amaranth (Amaranthus caudatus), quinoa (Chenopodium quinoa), canihua (Chenopodium pallidicaulle) - and two Andean roots starches - achira (Canna indica), maca (Lepidium meyenii) - were studied. Physicochemical properties such as granule size, crystallinity, pasting properties among other as well as structural properties such as root-mean-square radius (rrms), weight-average m

Partial safety factors for the anchorage capacity of corroded reinforcement bars in concrete

Many reinforced concrete bridges in Europe and around the world are damaged by reinforcement corrosion and the annual maintenance costs are enormous. It is therefore important to develop reliable methods to assess the structural capacity of corroded reinforced concrete structures and avoid unnecessary maintenance costs. Although there are advanced models for determining the load carrying capacity

Nanowire morphology and particle phase control by tuning the in concentration of the foreign metal nanoparticle

Controllable particle assisted growth (PAG) of III-V nanowires is today almost exclusively done with Au, Ga or In nanoparticles, whereas other metals often yield nanowires with uncontrolled growth directions. To improve the control of the initial growth direction in PAG, independent of choice of metal, we propose to initiate nanowire growth from a group-III-rich foreign metal particle. For III-V n

Patchiness and compensatory growth in a fungus-Collembola system

The compensatory growth potential of a grazed fungal biomass was mathematically expressed as a function of patchiness in its distribution and demonstrated in an experiment using the fungivorous collembolan Onychiurus armatus and the soil fungi Verticillium bulbillosum and Penicillium spinulosum. The model addresses the regrowth potential in relation to patch fragmentation, travelling time and cons

Global soil nitrous oxide emissions since the preindustrial era estimated by an ensemble of terrestrial biosphere models : Magnitude, attribution, and uncertainty

Our understanding and quantification of global soil nitrous oxide (N2O) emissions and the underlying processes remain largely uncertain. Here, we assessed the effects of multiple anthropogenic and natural factors, including nitrogen fertilizer (N) application, atmospheric N deposition, manure N application, land cover change, climate change, and rising atmospheric CO2 concentration, on global soil

Evaluating the machinability of Inconel 718 using polar diagrams

The use of a polar diagram method for describing and evaluating the machinability of Inconel 718 was explored. Five key parameters of the work material, representing the mechanical and physical properties which have strongest influence on its machinability, were employed in the diagrams. These five parameters were integrated into a single polar diagram, used to describe the machinability of Incone

Narratives of integration: Liminality in migrant acculturation through social media

Migrant integration is a long drawn out process requiring synergies with various dimensions of life, rhyming with those of the host country. In this paper, we attempt to deconstruct the digital narratives of migrant to explore how they may lead to a meaningful assessment of their acculturation and consequent integration in their host societies’. Drawing on acculturation theory as a lens, we argue

From breaking-ice to breaking-out: Integration as an opportunity creation process

This paper conducts an inductive case study to understand how the opportunity creation process leads to integration. It examines four cases of immigrant entrepreneurs of Cameroonian, Lebanese, Mexican and Assyrian origins who founded their businesses in Sweden. The study relies on process-oriented theory building and develops an inductive model of integration as an opportunity creation process. Th

Protein array profiling of circulating angiogenesis-related factors during bevacizumab containing treatment in metastatic colorectal cancer

Background Prolonged angiogenesis inhibition may improve treatment outcome in metastatic colorectal cancer (mCRC) patients. However, due to the complexity of the angiogenic pathways there is a lack of valid predictive biomarkers for anti-angiogenic agents. Here, we describe and optimize a procedure for simultaneous dynamic profiling of multiple angiogenesis related proteins in patient serum to exp

Visualization of adult fish lens fiber cells

The crystalline lens of a vertebrate eye is a gradient-index lens and grows throughout life by addition of new lens fiber cells in the periphery. In fish, the growing ball-shaped lens maintains sophisticated optical properties throughout life by maintaining the distribution of refractive index relative to the increasing radius of the lens. During this process, the central fibers must increase refr

Participation weighting based on sociodemographic register data improved external validity in a population-based cohort study

Objective: To investigate whether inverse probability of participation weighting (IPPW) using register data on sociodemographic and disease history variables can improve external validity in a cohort study with selective participation. Study Design and Setting: We fitted various IPPW models by logistic regression using register data for the participants (n = 1,111) and nonparticipants (n = 1,132)
