The strict orthology of mitochondrial (mt) coding sequences has promoted their use in phylogenetic analyses at different levels. Here we present the results of a mitogenomic study (i.e., analysis based on the set of protein-coding genes from complete mt genomes) of 60 mammalian species. This number includes 11 new mt genomes. The sampling comprises all but one of the traditional eutherian orders.
Objectives: To study the prevalence of comorbid conditions at diagnosis and during follow-up in a cohort of patients with early rheumatoid arthritis (RA) followed prospectively over 20 years, and to identify possible early predictive factors for future comorbidities. Methods: A community-based cohort of 183 patients (mean age 52 years, 63% female) with early RA was recruited between 1985 and 1989.
The hypotheses were based on conceiving of automatic mimicking as involved in emotional empathy. Mimicry reactions (EMG) in high- and low-empathy subjects were studied when subjects were exposed to pictures of angry or happy faces. The degree of correspondence between subjects’ facial EMG reactions and their self-reported feelings was compared. The comparisons were made at different stimulus expos
The respiratory pathogen Moraxella catarrhalis has a high affinity for human IgD and is mitogenic for peripheral blood B lymphocytes. Moraxella IgD-binding protein, which is a multifunctional outer membrane protein with adhesive properties, is responsible for the interaction. Previous experiments with the Ig-binding B cell superantigens protein A and protein L from Staphylococcus aureus and Peptos
The purpose of the present research was to examine if anxiety is linked to a memory-based attentional bias, in which attention to threat is thought to depend on implicit learning. Memory-based attentional biases were defined and also demonstrated in two experiments. A total of 168 university students were shown a pair of faces that varied in their emotional content (angry, neutral, and happy), wit
In this report we show that Tyr568 and Tyr570 are phosphorylated in vivo in the Kit/stem cell factor receptor (Kit/SCFR) following ligand-stimulation. By mutation of Tyr568 and Tyr570 to phenylalanine residues and expression of the mutated receptors in porcine aortic endothelial (PAE) cells, we could demonstrate a loss of activation of members of the Src family of tyrosine kinases when Tyr568 was
OBJECTIVE: To investigate the significance and pathogenic potential of a highly conserved major type II collagen triple-helical epitope-specific antibody (U1; amino acids 494-504) in vivo and in vitro in patients with early rheumatoid arthritis (RA) and in experimental animal models of collagen-induced arthritis (CIA). METHODS: U1-specific antibodies in sera from patients with early RA (with or wi
We have studied the electrical properties of cement mortars in the frequency range 10-4-107 Hz, for different water contents. The admittance scales as a power law with an exponent of about 0.7 in a wide frequency range. This behaviour is interpreted in terms of polarization and diffusion at fractal pore surfaces. We obtain a fractal dimension of 2.4, which is in good agreement with adsorption isot
Lifetimes in the 3d(10)np(2)P sequence in neutral copper were measured by time-resolved laser spectroscopy. Excitation from the ground state was performed with pulsed laser radiation in the; vuv spectral region, generated by resonant sum-difference four-wave mixing in krypton gas. The lifetimes were evaluated from recorded optical transients. For the np(2)P(J) states we find the following: tau(n =
Ordinary lipomas are cytogenetically characterized primarily by simple balanced chromosome aberrations with stable morphologies, most of which affect chromosome segment, 12q13-15, where the HMGA2 gene plays a key pathogenetic role. Atypical lipomatous tumors (ALTs) display supernumerary ring or giant marker chromosomes with amplification of several genes including HMGA2 and MDM2. A study of HMGA2
Cancer of unknown primary site (CUP) is a fatal cancer ranking among the five most common cancer deaths. CUP is diagnosed through metastases, which are limited to lymph nodes in some patients. Cause-specific survival data could guide the search for hidden primary tumors and help with therapeutic choices. The CUP patients were identified from the Swedish Cancer Registry between 1987 and 2008; 1444
Complement activation was studied in 45 patients undergoing total hip arthroplasty under epidural anesthesia. The patients were randomly allocated to three groups. In Group I blood loss was replaced with microaggregate-poor erythrocyte concentrate (SAGM-ERC) plus 3% dextran-60 as plasma substitute, and postoperative analgesia was maintained with intramuscular ketobemidone. In Group II blood loss w
1. The habitat heterogeneity (HHH) and individual adjustment (IAH) hypotheses are commonly proposed to explain a decrease in reproduction rate with increasing population density. Higher numbers of low-quality territories with low reproductive success as density increases lead to a decrease in reproduction under the HHH, while more competition at high density decreases reproduction across all terri
Epidemiological studies have shown an increased incidence of cancer among workers occupationally exposed to polycyclic aromatic hydrocarbons (PAHs). As the dermal route is considered important for exposure to PAHs in the workplace, the aim of this study was to develop and evaluate a tape-stripping technique for monitoring dermal exposure to pyrene and benzo(a)pyrene. The tape-stripping method was
The May 2009 Human Variome Project (HVP) Forum "Towards Establishing Standards" was a round table discussion attended by delegates from groups representing international efforts aimed at standardizing several aspects of the HVP: mutation nomenclature, description and annotation, clinical ontology, means to better characterize unclassified variants (UVs), and methods to capture mutations from diagn
In this chapter, we will cover the available design choices for enabling expression of two functional protein or RNA sequences from a single viral vector. Such vectors are very useful in the neuroscience-related field of neuronal control and modulation, e.g., using optogenetics or DREADDs, but are also desirable in applications of CRISPR/Cas9 in situ genome editing and more refined therapeutic app
Background: The aim of this study was to prospectively evaluate and report the experience of the use of continuous intravenous propofol sedation in a paediatric intensive care unit (PICU). Methods: All children younger than 16 years who were admitted to the PICU at a University Hospital for slightly more than a year and received propofol infusion were included prospectively and data were recor
