Interferon-alpha and ribavirin treatment of hepatitis C in children with malignancy in remission

Twenty-eight cases of hepatitis C virus (HCV) infection were identified in children in a pediatric oncology ward during 2 nosocomial outbreaks. HCV infection spontaneously cleared in 6 patients (21%). Eleven patients with persistent HCV viremia who had malignant diseases in remission after treatment were given a 48-week course of combined therapy with interferon-alpha (5x106 U 3 times weekly) and

Helicobacter pylori infection is associated with a decreased risk of developing oesophageal neoplasms

Background. The role of Helicobacter pylori infection in the development of oesophageal malignancies was investigated through a multivariate conditional logistic regression analysis in a nested case-control study. Methods. Blood samples and a questionnaire on smoking and alcohol habits were collected from a cohort of 32,906 city residents during a health-screening programme between 1974 and 1992.

Geriatric rehabilitation as an integral part of geriatric medicine in the Nordic countries

Objectives: First, to outline the theoretical and practical framework for geriatric rehabilitation in the Nordic countries and second, to survey the scientific medical publications for evidence-based geriatric rehabilitation. Methods: Brainstorming on geriatric rehabilitation in a working group of Nordic teachers in geriatric medicine. Papers on scientific programmes for geriatric rehabilitation f

Cervical carcinoma and reproductive factors: Collaborative reanalysis of individual data on 16,563 women with cervical carcinoma and 33,542 women without cervical carcinoma from 25 epidemiological studies.

The International Collaboration of Epidemiological Studies of Cervical Cancer has combined individual data on 11,161 women with invasive carcinoma, 5,402 women with cervical intraepithelial neoplasia (CIN)3/carcinoma in situ and 33,542 women without cervical carcinoma from 25 epidemiological studies. Relative risks (RRs) and 95% confidence intervals (CIs) of cervical carcinoma in relation to numbe

Gla-domain mutated human protein C exhibiting enhanced anticoagulant activity and increased phospholipid binding.

Protein C is a member of the vitamin K-dependent protein family. Proteins in this family have similar gamma-carboxyglutamic acid (Gla)-rich domains, but their affinities for negatively charged phospholipid membranes vary more. than 1000-fold.. We have shown that it is possible to enhance anticoagulant activity and membrane affinity of protein C by selective mutagenesis of the Gla domain. In this s

New directions for erectile dysfunction therapies.

Research in the field of erectile function and dysfunction has continued to expand rapidly. Based on the information available, some directions for future erectile dysfunction therapies can be identified. The first direction is improvement of current therapeutic principles. A second generation of orally active phosphodiesterase (PDE) inhibitors is being introduced, and further developments within

Effects of mycorrhizal colonization by Paxillus involutus on uptake of Ca and P by Picea abies and Betula pendula grown in unlimed and limed peat

Uptake of P(P-32) and Ca(Ca-45) by seedlings of Picea abies (L.) Karst and Betula pendula Roth, non-mycorrhizal or mycorrhizal with Paxillus involutus (Batsch: Fr) Fr. was studied. Seedlings were grown in unamended peat (pH 4.0) or in peat limed (CaO) to pH 5.1 or 6.1. A double-labelled (P-32 and Ca-45) complete nutrient solution was added to the peat 7 wk after planting. An 8 d period was allowed

An empirical parameterization of heterogeneous ice nucleation for multiple chemical species of aerosol

A novel, flexible framework is proposed for parameterizing the heterogeneous nucleation of ice within clouds. It has empirically derived dependencies on the chemistry and surface area of multiple species of ice nucleus (IN) aerosols. Effects from variability in mean size, spectral width, and mass loading of aerosols are represented via their influences on surface area. The parameterization is inte

Early enteral supply of fiber and Lactobacilli versus conventional nutrition: A controlled trial in patients with major abdominal surgery

OBJECTIVE: Early enteral nutrition with fiber-containing solutions plus Lactobacillus may reduce bacterial translocation and minimize the incidence of infections after surgery. METHODS: In a prospective, randomized trial in three groups (n = 30/group) of patients after major abdominal surgery, we compared our previous regimen with parenteral nutrition or fiber-free enteral nutrition (group A) with

Impact of drying and re-wetting on N, P and K dynamics in a wetland soil

As increased nutrient availability due to drainage is considered a major cause of eutrophication in wetlands rewetting of drained wetlands is recommended as a restoration measure. The effect of soil drying and rewetting on the contribution of various nutrient release or transformation processes to changed nutrient availability for plants is however weakly understood. We measured effects of soil dr

Greater reduction of urinary albumin excretion in hypertensive type II diabetic patients with incipient nephropathy by lisinopril than by nifedipine

A double-blind, randomised, parallel group, multicentre, multinational study compared the effects of 12 months' treatment with lisinopril (10-20 mg once daily) or nifedipine retard tablets (20-40 mg twice daily) in 239 males (aged 18-75 years) and 96 post-menopausal females (aged 40-75 years). They all had a history of clinically stable type II diabetes > 3 months, microalbuminuria and early diabe

Cysteine proteinase 30 (CP30) and antibody response to CP30 in serum and vaginal washes of symptomatic and asymptomatic Trichomonas vaginalis-infected women

Infection with Trichomonas vaginalis may be asymptomatic or with symptoms suggestive of vaginitis. Because cysteine proteinase 30 (CP30) of T. vaginalis is known to be a virulence marker that plays a role in cytoadherence, the aim of this study was to analyse the presence of CP30 and antibody to CP30 in clinical samples of symptomatic and asymptomatic infected women. CP30 was detected in all the s

Introducing tool support for retrospective analysis of release planning decisions

The release planning activity in market-driven requirements engineering is crucial but difficult. The quality of the decisions on product content and release timing determines the market success, but as predictions of market value and development cost are uncertain, the decisions are not always optimal. This paper presents a prototype tool for retrospective analysis of release planning decisions b

Ion-ion correlations in liquid dispersions

Ion-ion correlations play an important role in liquid dispersion with, strong eleetrostatic inlet-actions. Examples can be found in very diverse areas with the setting of cement paste as one extreme and the compactation, of DNA as another. One particularly spectacular effect of ion-ion correlations is that the traditional double layer repulsion sometimes can be converted into a net attraction. Thi

Molecular Structures of Citrate and Tricarballylate Adsorbed on alpha-FeOOH Particles in Aqueous Suspensions

In this work, the adsorption of citric (2-hydroxypropane-1,2,3-tricarboxylic acid) and tricarballylic (propane-1,2,3-tricarboxylic acid) acids onto alpha-FeOOH (goethite) in aqueous suspensions was studied as a function of pH and total ligand concentration in 0.1 M NaCl at 25.0 degrees C, and the molecular structures of the surface complexes formed were analyzed by means of ATR-FTIR spectroscopy.

Anticholinergic drug use for overactive bladder in Sweden: a nationwide pharmacoepidemiological study

Nationwide use and costs of anticholinergic drug for overactive bladder are unknown. We performed a nationwide study based on the Swedish Register on Prescribed Pharmaceuticals. From 2000 to 2007, there was a 68.8% increase in dispensed anticholinergic drugs in a population of 9 million. More than 93 million DDDs (calculated average maintenance dose per day) of anticholinergic drugs were dispensed

Radiographic measurements of severe temporomandibular joint destruction at cervical radiography. Designed for evaluation in rheumatoid arthritis

Radiological examinations of the temporomandibular joints are not so often performed in patients with rheumatoid arthritis (RA). However, greater abnormalities of the mandibular head and neck may be evaluated at cervical radiography. With a new method, where the perpendicular distance from the palato-occipital line to the mandibular angle was measured, normal values of the distance or of ramal hei

Luminescence polarization of ordered GaInP/InP islands

The luminescence polarization properties of GaInP islands have been investigated. The islands, which form during overgrowth of InP quantum dots, were studied using scanning tunneling luminescence (STL) and photoluminescence (PL). STL from these islands shows emission at an energy below the main emission peak of the bulk GaInP. The linear PL polarization anisotropy was measured at low temperature,
