Phosphodiesterase type 3B (PDE3B) has been shown to be activated and phosphorylated in response to insulin and hormones that increase cAMP. In order to study serine/threonine protein phosphatases involved in the regulation of rat adipocyte PDE3B, we investigated the phosphorylation and activation of PDE3B in vivo in response to phosphatase inhibitors and the dephosphorylation and deactivation of P

Aim To evaluate whether Long-term treatment with a fixed tow dose of warfarin in combination with aspirin improves the prognosis compared with aspirin treatment alone after an acute myocardial infarction (AMI). Methods Patients who were hospitalized for AMI were randomized to either 1.25 mg of warfarin plus 75 mg of aspirin (n=1659) daily or 75 mg of aspirin atone (n=1641). The study was performed

This study describes the removal of polycyclic aromatic hydrocarbons (PAHs) from creosote oil contaminated soil by modified Fenton's reaction in laboratory-scale column experiments and subsequent aerobic biodegradation of PAHs by indigenous bacteria during incubation of the soil. The effect of hydrogen peroxide addition for 4 and 10 days and saturation of soil with H2O2 on was studied. In both exp

Rodent models have been developed to study the pathogenesis of diseases caused by Helicobacter pylori, as well as by other gastric and intestinal Helicobacter spp., but some murine enteric Helicobacter spp. cause hepatobiliary and intestinal tract diseases in specific inbred strains of laboratory mice. To identify these murine Helicobacter spp., we developed an assay based on PCR-denaturing gradie

OBJECTIVES: To assess endothelial function and vascular mechanical properties in normotensive pregnant women with high resistance in the uteroplacental circulation. DESIGN: Cross-sectional prospective study. SETTING: Doppler ultrasound laboratory at university department of obstetrics and gynaecology referral centre for high risk pregnancies. PARTICIPANTS: Forty-two caucasian normotensive pregnant

The regional sensitivity of different vascular beds to i.v. CGRP was investigated in the albino rabbit by using the microsphere method. Experiments were performed without pre-treatment on both conscious and pentobarbital-anaesthetized animals. In addition, in one series on conscious animals, rabbits were pre-treated with indomethacin in order to reduce the formation of prostaglandins. In another s

About 25% of C2-deficient homozygotes have increased susceptibility to severe bacterial infections. C2-deficient homozygotes had significantly lower serum levels of IgG2, IgG4, IgD, and Factor B, significantly higher levels of IgA and IgG3 and levels of IgG1 and IgM similar to controls. Type I ( 28 bp deletion in C2 exon 6 on the [HLA-B18, S042, DR2] haplotype or its fragments) and type II ( non-t

PURPOSE: To compare the contrast effects of gadodiamide injection at 0.3 and at 1.5 T, at different concentrations in phantoms, and to correlate the results to clinical doses used for examining brain lesions. MATERIAL AND METHODS: Gel phantoms with T1 and T2 corresponding to brain gray matter were doped with different concentrations of gadodiamide injection and examined with T1-weighted sequences.

BACKGROUND AND OBJECTIVES: During the past 10 years several DNA-typing methods have been developed to complement routine serological typing for determination of polymorphisms in the ABO, RH, KEL, JK and FY blood group genes. However, the molecular basis of blood groups can differ widely between ethnic groups. The purpose of this study was to evaluate selected DNA-based methods for phenotype predic

Study Design. Biomechanical analysis of the movement of the lumbar spinal nerve roots (NRs). Objectives. The characteristics of the movement of lumbar spinal NRs corresponding to the change of posture were three-dimensionally analyzed in nonsimulated and simulated adhesion conditions using a porcine model. Summary of Background Data. There is a paucity of data on the movement of NRs. Materials and

BACKGROUND: The objective of this study was to assess, in a large data set from Swedish Medical Health Registries, whether maternal obesity and maternal morbid obesity were associated with an increased risk for various structural birth defects. METHODS: The study population consisted of 1,049,582 infants born in Sweden from January 1, 1995, through December 31, 2007, with known maternal weight and

Introduction: This research sought to extend knowledge about bystanders in bullying situations with a focus on the motivations that lead them to different responses. The 2 primary goals of this study were to investigate the reasons for children's decisions to help or not to help a victim when witnessing bullying, and to generate a grounded theory (or conceptual framework) of bystander motivation i

Background: Interactions between Th1 and Th2 immune responses are of importance to the onset and development of allergic disorders. A Toll-like receptor 7 agonist such as AZD8848 may have potential as a treatment for allergic airway disease by skewing the immune system away from a Th2 profile. Objective: To evaluate the efficacy and safety of intranasal AZD8848. Methods: In a placebo-controlled si

Most existing remote sensing-based evapotranspiration (ET) algorithms rely exclusively on polar-orbiting satellites with thermal infrared sensors, and therefore the resulting ET values represent only "instantaneous or snapshot" values. However, daily ET is more meaningful and useful in applications. In this study, daily ET estimates are obtained by combining data from the MODIS sensor aboard the p

Congenital haemophilia A and B are genetic disorders affecting factor VIII and factor IX production, respectively. Factor replacement is the only effective treatment for these deficiencies, but a patient's immune system can develop inhibitory antibodies which bind and interfere with the function of the replaced factor in a variety of ways. The main treatment goal for patients with inhibitors is to

OBJECTIVES:: To compare the plasma volume (PV) expanding effect of a fast infusion rate with that of a slow infusion rate of a fixed volume of 5% albumin, of the synthetic colloids, 6% hydroxyethyl starch 130/0.4 and 4% gelatin, and of 0.9% NaCl in a rat sepsis model and to compare the plasma-expanding effect among these fluids. DESIGN:: Prospective, randomized animal study. SETTING:: University h
