Avian Malaria infects thousands of species of birds across the Aves class. The most widespread (geographically and phylogenetically)morphological species is Plasmodium relictum, and of that, the mitochondrial lineage of SGS1 is the most common and invasive. It infects146 bird species, with large differences in infection outcome, from low intensity chronic disease to shorter, highly virulent infect
This article researches what body descriptions are present within Swedish biohacking, what roots they have, and what overlaps they create between biohacking and other philosophical, political, and scientific discourses. As biohacking has become an increasingly popular subcultural influence incontemporary culture, not least when it comes to individual responsibility for ones health, the aim of the
White dwarf stars represent the last evolutionary stage of most stars in the Universe. As many of half of these stars are known to have metals in their atmospheres, that must have entered the atmosphere recently. Some also have observable debris discs, hinting that remnant exoplanets provide an important puzzle piece. However, we do not know the full extent of their role, as it is very hard to obs
This study systematically investigates the passivation and dissolution mechanisms of TC4 (Ti-6Al-4V) in 3.5 wt% NaCl solution using in situ electrochemical atomic force microscopy (ECAFM), complemented by X-ray photoelectron spectroscopy (XPS) and X-ray absorption spectroscopy (XAS). Potentiodynamic polarization initially identified the electrochemical behavior of TC4, delineating passive, dissolv
The Hunga Tonga eruption on 15 January 2022 (HT-22) induced vigorous volcano–sea interaction. Here we study the stratospheric aerosol and water vapor resulting from the eruption using satellite-based instruments: the CALIOP lidar and the Microwave Limb Sounder (MLS). We investigate the stratospheric relative humidity following the record-breaking water vapor injections from the HT-22 eruption and
An economic process for the enzymatic hydrolysis of cellulose would allow utilization of cellulosic biomass for the production of easily fermentable low-cost sugars. New and more efficient fermentation processes are emerging to convert this biologic currency to a variety of commodity products with a special emphasis on fuel ethanol production. Since the cost of cellulase production currently accou
The rat hepatic artery responds to acetylcholine (ACh) with an endothelium‐dependent relaxation, which is unaffected by nitric oxide (NO) synthase and cyclooxygenase inhibition. The purpose of this study was to investigate whether the NO‐independent relaxation is caused by hyperpolarization of the smooth muscle cells. In vessels with endothelium ACh induced a hyperpolarization in the presence of 0
A technique to estimate fungal growth rates in field samples was tested in soil. The technique is based on the addition of C-14-acetate to a soil slurry and the subsequent uptake and incorporation of the labelled acetate into the fungus specific substance ergosterol by the fungi. The addition of fungal inhibitors decreased acetate incorporation rates, while bacterial inhibitors did not. Fungus-fre
We analysed 57 years’ uninterrupted trapping data of autumn migrating Ruddy Turnstones Arenaria interpres at Ottenby, south-eastern Sweden (1593 full-grown birds in 1947–2003; of them 574 birds with standardised trapping in 1976–2003). Numbers trapped decreased significantly for both adult and juvenile birds in the total dataset (–0.34 and –0.57 ringed birds per year), and for juveniles in the 197
Phytase is used as a feed additive for degradation of antinutritional phytate, and the enzyme is desired to be highly thermostable for it to withstand feed formulation conditions. A Bacillus sp. MD2 showing phytase activity was isolated, and the phytase encoding gene was cloned and expressed in Escherichia coli. The recombinant phytase exhibited high stability at temperatures up to 100 degrees C.
Objective: To explore the role of MTNR1B rs10830963 and G6PC2 rs560887 variants in the pathogenesis of impaired fasting glucose (IFG) in obese adolescents. Methods: A total of 346 Caucasians, 218 African-Americans, and 217 Hispanics obese children and adolescents underwent an oral glucose tolerance test (OGTT) and 518 underwent the evaluation of insulin secretion by the oral minimal model (OMM). A
Objective: To evaluate the internal consistency of the Hip disability and Osteoarthritis Outcome Score-Physical Function Short-form (HOOS-PS) and the Knee injury and Ostecarthritis Outcome Score-Physical Function Short-form (KOOS-PS) in total hip replacement (THR) and total knee (TKR) replacement. Construct validity and responsiveness were compared to the Western Ontario McMaster Universities' Ost
At the University Hospital of Malmo, Sweden, standardized trauma charts were used for registration of all jaw fractures from 1972 to 1976. During the year 2005 the aim was to interview all patients treated non-surgically for unilateral mandibular condylar fractures during this period. In total, 49 patients with unilateral condylar fractures were treated non-surgically in 1972-1976. Of these, 23 pa
A denuder/filter system constructed for solvent-free personal exposure measurements was evaluated for separation of vapour and particulate 4,4'-methylenediphenyl diisocyanate (4,4'-MDI) generated from heated PUR-foam. The two different phases were collected in the denuder and on the filter, respectively, by chemosorption on a polydimethylsiloxane (SE-30)-dibutylamine (DBA) stationary phase. Both r
Short-chain fatty acids (SCFAs) have attracted much attention recently because of their positive physiological effects. In this work, a rapid and reliable gas chromatographic method for determination of eight SCFAs, in colonic and faecal samples from rats and humans has been developed and validated. The methodology involves extraction of the SCFAs in water before a direct injection procedure on a
The German bread market is considered one of the most developed and diverse bread markets worldwide. However, until so far no empirical evidence exists with respect to consumers liking and willingness to pay for different value-added attributes in whole grain bread. Thus, our study is the first one providing empirical evidence on how German consumers perceive different value-added attributes in wh
Interstitial laser Doppler flowmetry was used to measure the effect of interstitial laser-induced thermotherapy on local blood perfusion in normal rat liver in the peripheral treatment region elevated to hyperthermic temperatures. The Nd:YAG laser emitting at 1064 nm was utilised as heat generation source. The plane-cut tip of an optical fibre was placed in the middle of the exteriorised left live
Kai Söderhjelm (b. 1918 in Helsinki, d. 1996 in Gothenburg) belonged to a Finland-Swedish cultural family, and was for many years an important and valuable figure in the intellectual life of Sweden. Söderhjelm’s authorship follows the same clear thematic lines from his first book, Rid mot nordväst (1948; Ride to the northwest), to his last, Okänt land (1993; Unknown land). These themes are peace,
Ternary isothermal (25°C) polyoxyalkylene triblock block copolymer ((EO)x(PO)y(EO)x where x is the number of ethylene oxide, EO, segments and y is the number of propylene oxide, PO, segments) systems with water and p-xylene as selective solvents for the PEO and PPO blocks, respectively, were chosen as study systems in this thesis as these ternary systems are good model systems for the self-assembl
