Effects of beta(3)-adrenoceptor stimulation on prostaglandin E-2-induced bladder hyperactivity and on the cardiovascular system in conscious rats

Aims. To investigate the effects of selective beta(2)- and selective beta(3)-adrenoceptor (AR) agonists on prostaglandin (PG) E-2-induced bladder hyperactivity in conscious free-moving rats. Methods. Female Sprague-Dawley rats were anesthetized for implantation of bladder, intravenous, and intra-arterial catheters. The effects of a beta(3)-AR agonist (CL316,243) on cystometric and cardiovascular p

Sex and environmental sensitivity in blue tit nestlings

In birds and mammals with sexual size dimorphism (SSD), the larger sex is typically more sensitive to adverse environmental conditions, such as food shortage, during ontogeny. However, some recent studies of altricial birds have found that the larger sex is less sensitive, apparently because large size renders an advantage in sibling competition. Still, this effect is not an inevitable outcome of

Elimination of damaged proteins during differentiation of embryonic stem cells

During mammalian aging, cellular proteins become increasingly damaged: for example, by carbonylation and formation of advanced glycation end products (AGEs). The means to ensure that offspring are born without such damage are unknown. Unexpectedly, we found that undifferentiated mouse ES cells contain high levels of both carbonyls and AGEs. The damaged proteins, identified as chaperones and protei

Oxytocin and oxytocin-receptor mRNA expression in the human gastrointestinal tract: a polymerase chain reaction study

Background/aim: Oxytocin (OT) has a wide range of effects throughout the body. However, the role of OT on the gastrointestinal (GI) tract has to be settled. So far, the few studies performed reveal no conclusive results. The aim of this study was to examine the expression of Of and OT-receptor mRNA in the human GI tract. Material and methods: Full-thickness biopsies from all segments of the GI tra

Intensive care sedation of mechanically ventilated patients: a national Swedish survey

Sedation in critically ill patients is a complex issue and at the same time an important concept for ensuring patient comfort. The aim of this study was to review the current practice of sedation for patients on mechanical ventilation in Swedish intensive care units (ICUs). Questionnaires were sent by post to head nurses in 89 ICUs with mechanically ventilated patients. By August 2000, 87 (98%) qu

Concentration of BNP, endothelin 1, pro-inflammatory cytokines (TNF-alpha, IL-6) and exercise capacity in patients with heart failure treated with carvedilol

Background: Recent studies on the pathophysiology of heart failure indicate the role of neurohormones and immune and inflammatory processes as potential mechanisms involved in the pathogenesis and clinical course of chronic heart failure (CHF). Aim: To analyse the relationship between concentrations of brain natriuretic peptide (BNP), endothelin-1 (ET-1), inflammatory cytokines (TNF-alpha, IL-6) a

Incidence and survival of squamous cell carcinoma of the tongue in Scandinavia, with special reference to young adults.

In several countries, increased incidence of squamous cell carcinoma (SCC) of the tongue in young adults has been suspected during the last decades. Some reports indicate a lower survival rate for young patients compared to older patients. In other reports, there has not been any considerable difference in survival when comparing young adults to older patients, whereas some authors have shown bett

Isolation, characterization and multiplex polymerase chain reaction of novel microsatellite loci for the avian parasite Philornis downsi (Diptera: Muscidae)

An enrichment technique was used to isolate 11 di-, tri-, and tetra microsatellites for the parasitic fly Philornis downsi (Diptera: Muscidae). These loci were polymerase chain reaction amplified in singleplexes or two-plexes for P. downsi. The loci showed low to moderate polymorphism, exhibited between three and four alleles, and observed heterozygosity ranged from 0.05 to 0.86. These new markers

Cocaine and amphetamine regulated transcript (CART) in suicide attempters.

Cocaine and amphetamine regulated transcript (CART) is a neuropeptide expressed in brain regions thought to regulate anxiety levels, depression, addiction and energy homeostasis. Individuals with a CART mutation display increased anxiety and depression. Severe anxiety is a core phenomenon of suicidality. We therefore studied levels of CART in the cerebrospinal fluid (CSF) of 98 patients with diffe

Comparison of DEM Data Capture and Topographic Wetness Indices

Digital elevation models (DEMs) can be captured and analysed by various methods. Elevation capturing with RTK-GPS and airborne laser scanning is presented and evaluated in terms of height accuracy of raw data and interpolated DEMs for study sites in Sweden and Germany. Applications for precision agriculture are based on the connection of land surface and the movement of water in the landscape. Thr

Differential expression of myrosinase gene families

In mature seeds of Brassica napus three major and three minor myrosinase isoenzymes were identified earlier. These myrosinases are known to be encoded by at least two different families of myrosinase genes, denoted MA and MB. In the work described in this paper the presence of different myrosinase isoenzymes in embryos, seedlings, and vegetative mature tissues of B. napus was studied and related t

Cell-specific and efficient expression in mouse and human B cells by a novel hybrid immunoglobulin promoter in a lentiviral vector

The expression of genes specifically in B cells is of great interest in both experimental immunology as well as in future clinical gene therapy. We have constructed a novel enhanced B cell-specific promoter (Igk- E) consisting of an immunoglobulin kappa (Igk) minimal promoter combined with an intronic enhancer sequence and a 30 enhancer sequence from Ig genes. The Igk- E promoter was cloned into a

Inhibitors of dipeptidyl peptidase IV: a novel approach for the prevention and treatment of Type 2 diabetes?

Inhibitors of the enzyme dipeptidyl peptidase IV (DPP IV) are of increasing interest to both diabetologists and the pharmaceutical industry alike, as they may become established as the next member of the oral antidiabetic class of therapeutic agents, designed to lower blood glucose and, possibly, prevent the progressive impairment of glucose metabolism in patients with impaired glucose tolerance a

Maternal Epstein-Barr virus and cytomegalovirus infections and risk of testicular cancer in the offspring: a nested case-control study

During recent decades the incidence of testicular cancer (TC) has increased rapidly around the world. Associated exogenous etiological factors might therefore be identifiable. We performed a case-control study nested within Finnish, Swedish and Icelandic maternity cohorts exploiting early pregnancy serum samples to evaluate the role of congenital or neonatal infections with Epstein-Barr virus (EBV

Acoustic modelling of earplugs

Experimental Two-Port data is used to model the acoustical behavior of three fundamentally different types of earplugs. It is shown that simple lumped models suffice to describe the acoustical behavior of the earplugs. Furthermore, it is shown that the measurement setup can advantageously be used to assess the acoustical properties of an arbitrary acoustical partition for a wide frequency range.

A risk haplotype of STAT4 for systemic lupus erythematosus is over-expressed, correlates with anti-dsDNA and shows additive effects with two risk alleles of IRF5

Systemic lupus erythematosus (SLE) is the prototype autoimmune disease where genes regulated by type I interferon (IFN) are over-expressed and contribute to the disease pathogenesis. Because signal transducer and activator of transcription 4 (STAT4) plays a key role in the type I IFN receptor signaling, we performed a candidate gene study of a comprehensive set of single nucleotide polymorphism (S

Collagen type II-specific monoclonal antibody-induced arthritis in mice - Description of the disease and the influence of age, sex, and genes

Transfer of collagen type H (CH)-specific monoclonal antibodies induces an acute form of arthritis (collagen type H antibody-induced arthritis, CAIA) in nave mice. Arthritis was induced using a pair of monoclonal antibodies M2139 and CIIC1, binding to J1 and C1(I) epitopes of CH, respectively. Thereafter, lipopolysaccharide injection was used to increase the incidence and severity of the disease.

Load-bearing increases new bone formation in impacted and morselized allografts

The effects of mechanical loading on the incorporation of morselized impacted grafts were addressed in this study. Twelve skeletally mature rabbits were surgically treated. Six rabbits received a proximal tibial joint replacement with a tibial tray and a load-bearing 25-mm long stem. The tibia was packed with fresh frozen, morselized, cancellous rabbit bone. No cement was used. In six other rabbit
