Molecular evolution of the mammalian alpha 2B adrenergic receptor

The alpha 2B adrenergic receptor (A2AB) is a heptahelical G protein-coupled receptor for catecholamines. We compared the almost complete coding region (about 1,175 bp) of the A2AB gene from 48 mammalian species, including eight newly determined sequences, representing all the 18 eutherian and two marsupial orders. Comparison of the encoded proteins reveals that residues thought to be involved in a

Critical role of CXC chemokines in endotoxemic liver injury in mice.

Tissue accumulation of leukocytes constitutes a rate-limiting step in endotoxin-induced tissue injury. Chemokines have the capacity to regulate leukocyte trafficking. However, the role of CXC chemokines, i.e., macrophage inflammatory protein-2 (MIP-2) and cytokine-induced neutrophil chemoattractant (KC), in leukocyte recruitment, microvascular perfusion failure, cellular injury, and apoptosis in t

A central core structure in an antibody variable domain determines antigen specificity

Antibody binding sites provide an adaptable surface capable of interacting with essentially any molecular target. Using CDR shuffling, residues important for the assembly of mucin-1 specific paratopes were defined by random recombination of the complementarity determining regions derived from a set of mucin-1 specific clones, previously selected from an antibody fragment library. It was found that

Perlecan is critical for heart stability

Perlecan is a heparansulfate proteoglycan found in basement membranes, cartilage, and several mesenchymal tissues that form during development, tumour growth, and tissue repair. Loss-of-function mutations in the perlecan gene in mice are associated with embryonic lethality caused primarily by cardiac abnormalities probably due to hemopericards. The aim of the present study was to investigate the m

Patient experiences of basic body awareness therapy and the relationship with the physiotherapist.

Background and Purpose: To explore the experiences of patients undergoing basic body awareness therapy in psychiatric physiotherapy. In addition, the therapeutic relationship and the concept of the working alliance were examined. Subjects: Two groups of patients participated: patients with schizophrenia (n=6) and general psychiatric outpatients (n=5). Method: A qualitative technique, video taping

Serum CK-MB is useful in diagnosis of acute myocardial infarction after total hip arthroplasty

Skeletal muscle trauma and myocardial infarction both increase the serum values of the creatine kinase isoenzyme MB (CK-MB) which may render the diagnosis of perioperative myocardial infarction in major orthopaedic surgery more difficult. The significance of postoperative changes in CK-MB was studied in 30 patients subjected to total hip replacement (THR), and the results were compared to CK-MB in

Catalysis by RNase P RNA. Unique Features and Unprecedented Active Site Plasticity.

Metal ions are essential cofactors for precursor tRNA (ptRNA) processing by bacterial RNase P. The ribose 2'-OH at nucleotide (nt) –1 of ptRNAs is known to contribute to positioning of catalytic Me2+. To investigate the catalytic process, we used ptRNAs with single 2'-deoxy (2'-H), 2'-amino (2'-N), or 2'-fluoro (2'-F) modifications at the cleavage site (nt –1). 2' modifications had small (2.4–7.7-

Hypertension prevalence in obstructive sleep apnoea and sex: a population-based case-control study

Obstructive sleep apnoea (OSA) is a recognised risk factor for hypertension (HT). The current authors investigated confounders of this association in a sex-balanced community-based sample of patients with HT (n=161) from the Skaraborg Hypertension and Diabetes Project (n=1,149) and normotensive controls (n=183) from an age and sex stratified community-based population sample (n=1,109). All partici

Polymorphisms at newly identified lipid-associated loci are associated with blood lipids and cardiovascular disease in an Asian Malay population

We conducted a cross-sectional study of Malay articipants aged 40-80 years (n = 2,932) to examine the associations between polymorphisms at newly identified, lipid-associated loci with blood lipid levels and prevalent cardiovascular disease (CVD) in a Malay population in Asia. A polymorphism adjacent to the TRIB1 locus (rs17321515) was associated with elevated total cholesterol and LDL-cholesterol

Mechanism of action, development and clinical experience of recombinant FVIIa.

Recombinant FVIIa has been developed for treatment of bleedings in hemophilia patients with inhibitors, and has been found to induce hemostasis even during major surgery such as major orthopedic surgery. Recombinant FVIIa is being produced in BHK cell cultures and has been shown to be very similar to plasma-derived FVIIa. The use of rFVIIa in hemophilia treatment is a new concept of treatment and

Tense morphology and verb-second in Swedish L1 children, L2 children and children with SLI

This paper compares the development of tense morphology and verb-second in different learner populations. Three groups of Swedish pre-school children are investigated longitudinally; ten L1 children, ten L2 children and ten children diagnosed with Specific Language Impairment (SLI). Data was collected twice, with an interval of six months. The results at Time I reveal a significant difference betw

Income and short-term case fatality after myocardial infarction in the whole middle-aged population of Malmo, Sweden.

BACKGROUND: There are no previous studies investigating when and where those who die pre-hospitally after an AMI paid their last visit to medical care. Methods and RESULTS: Incidence of AMI, pre-hospital and 28-day case fatality rates were monitored over 13 years of follow-up, in relation to sex-specific quartiles of annual income in all inhabitants aged 40-64 years in Malmö, Sweden. Both incidenc

Food patterns and components of the metabolic syndrome in men and women: a cross-sectional study within the Malmo Diet and Cancer cohort

This study examined the relations between food patterns and five components of the metabolic syndrome in a sample of Swedish men (n = 2,040) and women (n = 2,959) aged 45-68 years who joined the Malmo Diet and Cancer study from November 1991 to February 1994. Baseline examinations included an interview-administered diet history, a self-administered questionnaire, blood pressure and anthropologic m

FISH mapping of i(7q) in acute leukemias and myxoid liposarcoma reveals clustered breakpoints in 7p11.2 : implications for formation and pathogenetic outcome of the idic(7)(p11.2)

Isochromosome 7q - i(7q) - is seen in a wide variety of hematologic malignancies and solid tumors, often as a secondary change to a characteristic primary translocation. Despite its high frequency, nothing is known about the formation and the pathogenetic outcome of this abnormality. To address these issues, we performed a detailed fluorescence in situ hybridization (FISH) investigation of four ac

Defining dry/wet spells for point observations, observed area averages, and regional climate model gridboxes in Europe

A new method for optimising threshold values of dry/wet spells is evaluated. A set of indices is used to find the best threshold giving good correspondence between the frequency of dry/wet spells in Hadley Centre regional model (HadRM3) output, reference observations with predetermined thresholds, and area-averaged observations. The analyses focus on selected model gridboxes in 3 different Europea

Allozyme diversity in relation to geographic distribution and population size in Lathyrus vernus (L.) Bernh. (Fabaceae)

Lathyrus vernus (L.) Bernh. is a diploid, long-lived perennial and insect-pollinated herb with no special adaptation to long-distance dispersal. It occurs on neutral soil in deciduous forests throughout western Eurasia. Due to specific habitat preferences, L. vernus has a fragmented distribution with isolated populations. We investigated allozyme variation at eleven loci in 20 populations of L. ve

Combined use of active and passive surface waves

With a surface wave method to estimate shear-wave velocity (Vs) from dispersion curve(s) of known mode(s), accurate modal identification is obviously a crucial issue. In this regard, the dispersion imaging method is an essential processing tool as it can unfold the multi-modal nature of surface waves through direct wavetield transformations. When a combined dispersion curve of an extended frequenc
