The mouthparts of anuran tadpoles are highly derived compared to those of caecilians or salamanders. The suprarostral cartilages support the tadpole's upper beak; the infrarostral cartilages support the lower beak. Both supra- and infrarostral cartilages are absent in other vertebrates. These differences reflect the evolutionary origin of a derived feeding(More)
Myeloperoxidase (MPO) is a prime candidate for promoting oxidative stress during inflammation. This abundant enzyme of neutrophils uses hydrogen peroxide to oxidize chloride to highly reactive and toxic chlorine bleach. We have identified 2-thioxanthines as potent mechanism-based inactivators of MPO. Mass spectrometry and x-ray crystal structures revealed(More)
A resistivity and time-domain induced polarization (IP) survey was conducted at a landfill site under restoration at Härlöv in Southern Sweden. The covering of the landfill had begun some years ago, without keeping precise records of the work done, as is usual in such procedures. The survey was conducted in two steps, on two adjacent areas. First, a number(More)
A majority of xenobiotics are metabolized by cytochrome P450 (CYP) enzymes. The discovery of drug candidates with low propensity to form reactive metabolites and low clearance can be facilitated by understanding CYP-mediated xenobiotic metabolism. Being able to predict the sites where reactive metabolites form is beneficial in drug design to produce drug(More)
Homocracy, a term referring to shared regulatory gene expression patterns between organs in different animals, was introduced recently in order to prevent inappropriate inference of organ homology based on gene expression data. Non-homologous structures expressing homologous genes, and homologous structures expressing non-homologous genes illustrate that(More)
To encrypt messages with traditional methods, a stream of pseudo-random numbers must be generated to interact with the message according to the encryption algorithm. In our project we look into the possibility of using chaotic functions to provide such streams of random numbers, thereby providing integrity to the encryption key since the chaotic functions(More)
OBJECTIVE To determine the workplace concentrations of NO and NO(2) in and around a paediatric incubator during inhaled NO (iNO) treatment and during an accidental emptying of NO cylinders into room air. DESIGN We simulated iNO-nasal CPAP treatment in order to assess the impact on the occupational environment. Furthermore, two full NO cylinders for(More)
OBJECTIVE To explore the acute effects of inhaled nitric oxide (iNO) on oxygenation, respiratory rate, and CO2 levels in spontaneously breathing preterm infants treated with nasal continuous positive airway pressure (nCPAP) for moderate respiratory distress syndrome (RDS). DESIGN AND SETTING Randomized, prospective, double-blind, cross-over study in the(More)
The pharmacology and regulation of Transient Receptor Potential Ankyrin 1 (TRPA1) ion channel activity is intricate due to the physiological function as an integrator of multiple chemical, mechanical, and temperature stimuli as well as differences in species pharmacology. In this study, we describe and compare the current inhibition efficacy of human TRPA1(More)
The migratory insertion of propene into the Pd-phenyl bond of a set of neutral palladium(II) complexes with N-N, P-O, and N-O chelating ligands has been investigated by using density functional methods. In contrast to cationic palladium(II)-diimine complexes, which favor 1,2-insertion, the more electron-rich neutral complexes lead to 2,1-insertion. Trans(More)
