A plant bioassay was used to enumerate infectious Frankia in soil and micro- and molecular techniques were used to identify possible mechanisms by which Frankia survive drying.Myrica-nodulating Frankia occurred in five Hawaiian volcanic deposits with depositional ages ranging from 20 to 162 years before present. The oldest deposit had a mean estimated nodulation capacity from 450 to 1200 times gre
The Uppsala university coin cabinet harbours arather unusual numismatic treasure, a ‘screw-thaler’ from Augsburg, produced in the secondhalf of the 17th century. The object combines twothalers from Augsburg, one from 1632 portrayingthe Swedish king Gustavus Adolphus, and theother one coined 1658 displaying the city ofAugsburg. One side of both coins is polished aswell as hollowed out, and the rim
Om tidigmodern ärekränkande svensk och dansk begravningspoesi, med utgångspunkt i Christina Holst Færchs stuide Smædeskrifter, sladder og erotiske vers i 1700-tallet. Hans Nordrups forfatterskab, København 2019.
Experimental studies have suggested an atheroprotective role of interleukin (IL)-5 through the stimulation of natural immunoglobulin M antibody expression. In the present study we show that there are no associations between baseline levels of IL-5 and risk for development of coronary events or stroke during a 15.7 ± 6.3 years follow-up of 696 subjects randomly sampled from the Malmö Diet and Cance
In recent years, several Swedish companies have been accused in the media, by NGOs, and via legal proceedings of engaging in criminal activities. Two of these companies, TeliaSonera and Lundin Petroleum have been the focus of substantial public attention. During the years following the revelations that TeliaSonera, a partly state owned telecommunications company, had committed bribery offences in
In comparison to other human cancer types, malignant melanoma exhibits the greatest amount of heterogeneity. After DNA-based detection of the BRAF V600E mutation in melanoma patients, targeted inhibitor treatment is the current recommendation. This approach, however, does not take the abundance of the therapeutic target, i.e., the B-raf V600E protein, into consideration. As shown by immunohistoche
Upprinnelsen till detta specialnummer är frågan om hur dagens forskning om läsning och skrivning kan möta framtidens behov av undervisning för individen och i klassrummet. Både läsning och skrivning är komplexa aktiviteter, och för att vi till fullo ska förstå dem och kunna bidra till utveckling av skolans praktiker krävs att kunskaper från (ett antal) olika forskningsfält integreras.
Heart failure (HF) is a major public health problem characterized by inability of the heart to maintain sufficient output of blood. The systematic characterization of circulating proteins across different stages of HF may provide pathophysiological insights and identify therapeutic targets. Here we report application of aptamer-based proteomics to identify proteins associated with prospective HF i
We evaluated the performance of CSF biomarkers for predicting risk of clinical decline and conversion to dementia in non-demented patients with cognitive symptoms. CSF samples from patients in two multicentre longitudinal studies (ADNI, n = 619; BioFINDER, n = 431) were analysed. Aβ(1–42), tTau and pTau CSF concentrations were measured using Elecsys CSF immunoassays, and tTau/Aβ(1–42) and pTau/Aβ(
What is internal communication? What role does it play in contemporary organizations? What are the consequences of malfunctioning internal communication? There are many aspects of internal communication – work related, social, formal, informal, vertical, horizontal, between coworkers, between coworkers and managers, communication before and under organizational changes, internal crisis communicati
The last decade has seen a range of studies using non-invasive neutron and X-ray techniques to probe the ultrastructure of a variety of photosynthetic membrane systems. A common denominator in this work is the lack of an explicitly formulated underlying structural model, ultimately leading to ambiguity in the data interpretation. Here we formulate and implement a full mathematical model of the sca
Passerine birds belong to the most species rich bird order and are found in a wide range of habitats. The extremely polymorphic adaptive immune system of passerines, identified through their major histocompatibility complex class I genes (MHC-I), may explain some of this extreme radiation. Recent work has shown that passerines have higher numbers of MHC-I gene copies than other birds, but little i
This work reports a method to select the optimal working frequency in transversal bulk resonator acoustophoretic devices by electrical impedance measurements. The impedance spectra of acoustophoretic devices are rich in spurious resonance peaks originating from different resonance modes in the system not directly related to the channel resonance, why direct measurement of the piezoelectric transdu
Background: Epilepsy patients commonly exercise less than the general population. Animal studies indicate beneficial effects of physical activity in established epilepsy, while its effect on the development is currently less known. Methods: Here, we investigated the incidence of epilepsy during 20 years in a cohort of participants from the long-distance Swedish cross-country ski race Vasaloppet (n
In epilepsy patients, drug-resistant seizures often originate in one of the temporal lobes. In selected cases, when certain requirements are met, this area is surgically resected for therapeutic reasons. We kept the resected tissue slices alive in vitro for 48 h to create a platform for testing a novel treatment strategy based on neuropeptide Y (NPY) against drug-resistant epilepsy. We demonstrate
Background: Computed tomography (CT) scans are routinely performed in positron emission tomography (PET) and single photon emission computed tomography (SPECT) examinations globally, yet few surveys have been conducted to gather national diagnostic reference level (NDRL) data for CT radiation doses in positron emission tomography/computed tomography (PET/CT) and single photon emission computed tom
In this paper, we study event-based PID control from an optimal stochastic control perspective. The purpose is to better understand what implementation features are critical for achieving good event-based PID performance. For this end, we formulate an LQG control design problem for a double integrator process with an integral disturbance, where the solution is an ideal PID controller. We then cons
A technique for scalable spray coating of colloidal CdSeTe quantum dots (QDs) for photovoltaics and photodetector applications is presented. A mixture solvent with water and ethanol was introduced to enhance the adhesive force between QDs and the substrate interface. The performance of the detector reached the highest values with 40 spray coating cycles of QD deposition. The photodetectors without
