1. Given the allometric scaling of thermoregulatory capacity in birds, and the cold and exposed Arctic environment, it was predicted that Arctic-breeding shorebirds should incur high costs during incubation. Using doubly labelled water (DLW), daily energy expenditure (DEE) during incubation was measured in eight shorebird species weighing between 29 and 142 g at various sites in the Eurasian and C
OBJECTIVE: Huntington disease (HD) is a fatal autosomal dominant, neurodegenerative condition characterized by progressively worsening motor and nonmotor problems including cognitive and neuropsychiatric disturbances, along with sleep abnormalities and weight loss. However, it is not known whether sleep disturbances and metabolic abnormalities underlying the weight loss are present at a premanifes
The electric and magnetic polarizabilities of the proton are now well known, owing to Compton scattering measurements on hydrogen targets; however, the neutron polarizabilities are still relatively uncertain, compared to the proton values. To address this problem, a multiinstitutional collaboration has conducted a program of elastic Compton scattering experiments on deuterium at the MAX IV Laborat
IntroductionThe World Health Organization (WHO) has concluded that physical inactivity and overweight/obesity are the world's fourth and fifth leading risk factors for non-communicable diseases, respectively. This article investigates the potential for active commuting by bicycle in Scania county, southern Sweden, and its possible impact on public health. Physical inactivity is a growing problem o
Arguably among the most globally impactful climate changes in Earth's past million years are the glacial terminations that punctuated the Pleistocene epoch. With the acquisition and analysis of marine and continental records, including ice cores, it is now clear that the Earth's climate was responding profoundly to changes in greenhouse gas
Sediment transport in the cross-shore (CS) and associated changes in the beach profile, especially during storms, have been topics of widespread concern. Since storms are often accompanied by high water levels and large waves, large quantities of sand from the beach and the dune are typically transported offshore, leading to severe beach and dune erosion, which threatens the integrity of buildings
We present 63 new multi-site radial velocity (RV) measurements of the K1III giant HD 76920, which was recently reported to host the most eccentric planet known to orbit an evolved star. We focused our observational efforts on the time around the predicted periastron passage and achieved near-continuous phase coverage of the corresponding RV peak. By combining our RV measurements from four differen
Hovering insects are divided into two categories: ‘normal’ hoverers that move the wing symmetrically in a horizontal stroke plane, and those with an inclined stroke plane. Normal hoverers have been suggested to support their weight during both downstroke and upstroke, shedding vortex rings each half-stroke. Insects with an inclined stroke plane should, according to theory, produce flight forces on
Human cystatin C (hCC) is a cysteine proteinase inhibitor involved in pathophysiological processes of dimerization and amyloid formation. These processes are directly associated with a number of neurodegenerative disorders such as Alzheimer disease or hereditary cystatin C amyloid angiopathy (HCCAA). One of the ideas on how to prevent amyloid formation is to use immunotherapy. HCC3 is one of a gro
Concerns regarding environmental issues have led to increasing efforts for investigating sustainable production routes for the future industry that is based on renewable resources. Among the biobased chemicals, the C3-chemicals 3-hydroxypropionaldehyde (3-HPA), 1,3-propanediol (1,3-PDO) and 3-hydroxypropionic acid (3-HP), have been identified as top candidates for the chemical industry. Lactobacil
Acoustically robust light weight constructions in multifamily houses require that the building processes are taken into account, i.e. it is necessary to describe in detail how to erect the house on site in order to fulfill the final result. Performance of details necessary for stability reasons, connections in joints, fixing of final strips etc have to be described clearly in order to achieve the
Aeolian deposits in Sweden and Norway are poorly explored as environmental records. Many, mainly small, occurrences of windblown sand have been mapped, but few have been investigated in any detail and even fewer have been absolutely dated. Here we present results from a project aiming to determine the timing and magnitude of wind activity in inland settings in southern Sweden and Norway and to bet
α1-Adrenergic receptors from the cultured smooth muscle cell line (DDT1 MF-2) have been solubilized with digitonin and purified to apparent homogeneity by sequential chromatography on a biospecific affinity support (Sepharose-A55453 (4-amino-6,7-dimethoxy-2-[4-[5-(4-amino-3-phenyl)pentanoyl]- 1-piperazinyl]-quinazoline), an α1 receptor-selective antagonist), a wheat germ agglutinin-agarose gel, an
The effects of central cholinergic blockade on spatial memory were tested in aged and basal forebrain-lesioned rats using the Morris Water Maze. In Experiment 1, aged rats (18-21 months old) were characterized as behaviorally impaired or nonimpaired based on water maze performance prior to an atropine sulfate challenge. In the atropine test (50 mg/kg, IP), both the impaired and the nonimpaired rat
Continuously indexed Gaussian fields (GFs) is the most important ingredient in spatial statistical modelling and geo-statistics. The specification through the covariance function gives an intuitive interpretation of its properties. On the computational side, GFs are hampered with the "big-n" problem, since the cost of factorising dense matrices is cubic in the dimension. Although the computational
Abstract Objectives. To establish a set of reference values for regional dispersion of repolarization of the right atrium in the in situ heart of pigs and to see if the global dispersion of repolarization could be estimated from regional mapping. Design. Monophasic action potential (MAP) were sequentially recorded from 28 ± 3 sites in seven different regional areas of the right atrium: lateral, a
Protein structure-function relationships can be studied by using linker insertion mutagenesis, which efficiently identifies essential regions in target proteins. Bacteriophage Mu in vitro DNA transposition was used to generate an extensive library of pentapeptide insertion mutants within the alpha-complementing domain 1 of Escherichia coli beta-galactosidase, yielding mutants at 100% efficiency. E
Charlotte Perkins Gilman var en amerikansk författare, föreläsare ochdebattör. Hon är känd för att ha utarbetat en begreppsapparat kringdet vi i dag kallar genus, men hennes sociologi innefattar även ekonomisksociologi och kultursociologi. Hon vigde sitt liv åt offentlig sociologi,att göra sociologisk kunskap tillgänglig för allmänheten och varaen stark röst i det dåtida intellektuella samtalet i
Background: Acute bacterial meningitis is a bacterial infection of the membranes that surround and protect the brain, known as the meninges. The primary therapy for bacterial meningitis is antibiotics and corticosteroids. Although these therapies significantly improve outcomes, bacterial meningitis still has a high risk of death and a high risk of neurological sequelae in survivors. New adjuvant t
Over the past two decades there has been increased interest in orphan drug development for rare diseases. However, hurdles to clinical trial design for these disorders remain. This phase 1a/1b study addressed several challenges, while evaluating the safety and tolerability of the novel oral molecule KL1333 in healthy volunteers and subjects with primary mitochondrial disease.KL1333 aims to normali
