Holocene changes in atmospheric circulation recorded in the oxygen-isotope stratigraphy of lacustrine carbonates from northern Sweden

The oxygen-isotope composition of local precipitation (delta(18)O(P)) is reconstructed from carbonate lake-sediment components in a sediment core covering the last 10000 calendar years from Lake Tibetanus, a small, hydrologically open, groundwater-fed take in the Abisko area, northern Sweden. Comparison of the delta(18)O(P) history with a pollen-based palaeotemperature record from the same core cl

Pharmacokinetics of doxorubicin in children with acute lymphoblastic leukemia: Multi-institutional collaborative study

Background, In adults, it has been shown that the pharmacokinetics of doxorubicin are highly variable, despite standardization of the dose based on body surface area (BSA). The purpose of this study was to determine the plasma concentrations of doxorubicin and its active metabolite doxorubicinol in children treated for acute lymphoblastic leukemia (ALL). Procedure. Children, 107 in number, aged 1.

Transcriptional profiling and assessment of cell lines as in vitro models for mantle cell lymphoma

Mantle cell lymphoma (MCL) is an aggressive malignancy and new treatment modalities must be established to increase patient survival time. In the search for new therapeutic targets, reliable and well-characterised in vitro models are essential. In this study, we have characterised three MCL cell lines (SP53, Granta 519 and NCEB1) in comparison with primary tumors front MCL, follicular lymphomas (F

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

Antimuscarinic drugs in detrusor overactivity and the overactive bladder syndrome: motor or sensory actions?

Antimuscarinic drugs are generally thought to exert their therapeutic action on detrusor overactivity by reducing the ability of the detrusor muscle to contract. We review currently available published data to establish whether there is any evidence to support this contention. Using a PubMed data search, only 14 original articles (including two abstracts) were found that contained cystometric data

Changes in calcium metabolic indices during long-term treatment of patients with essential hypertension

1. Disturbances of calcium metabolism, mimicking mild, compensated secondary hyperparathyroidism, accompany essential hypertension, but it is not known whether these alterations are primary or only secondary to the elevated blood pressure. 2. Indices of systemic calcium metabolism were followed prospectively during 6 months' treatment with either propranolol, bendroflumethiazide or verapamil in 35

Awareness and treatment of cardiovascular disease risk factors among middle-aged Swedish men and women

OBJECTIVE: To study awareness and treatment of risk factors for cardiovascular disease in a primary care district where a screening program for hypercholesterolaemia involving one third of the population had been conducted 7 years earlier. DESIGN: A semi-structured telephone survey on four risk factors; blood pressure, serum cholesterol, blood sugar, and smoking habits. SETTING: The study was perf

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

Lectotypifications and notes on the application of names of Hieracium sect. Hieracium, sect. Bifida and sect. Vulgata (Asteraceae) based on material from the province of Dalarna, central Sweden

Lectotypes are designated for 174 names of taxa described based on material from the Swedish province of Dalarna and accepted to belong to Hieracium sect. Hieracium, sect. Bifida and sect. Vulgata. The taxonomic and nomenclatural implications, i.e. taxonomic synonyms and infraspecific taxa not worthy of taxonomic recognition, of the lectotypifications are discussed. Three new combinations, H. mund

Prebiotic oligosaccharides in dietetic products for infants: A commentary by the ESPGHAN committee on nutrition

This article by the ESPGHAN Committee on Nutrition summarizes available information on the effects of adding prebiotic oligosaccharides to infant and follow-on formulae. Currently there are only limited studies evaluating prebiotic substances in dietetic products for infants. Although administration of prebiotic oligosaccharides has the potential to increase the total number of bifidobacteria in f

Investigation of the adsorption of PEG1500-12-acyloxystearate surfactants onto phospholipid bilayers: An ellipsometry and Cryo-TEM study

In this article we present a study of a new class of surfactants denoted as PEG1500-12-acyloxystearates, which have potential use as pharmaceutical solubilizers. These amphiphilic molecules present interesting properties with regard to cell damage effects. PEG1500-12-acyloxystearates with C-14 to C-16 acyloxy chains cause little or no damage to red blood and intestinal cells, whereas the surfactan

Neuropeptide-containing nerve fibers in the pharynx of the rabbit

The distribution of peptide-containing nerve fibers in the pharyngeal region of rabbits was studied by immunocytochemistry. Neuropeptide Y (NPY)-containing fibers were numerous around blood vessels and moderate in number among bundles of striated muscle fibers. A few NPY-containing fibers were seen around seromucous glands and beneath the epithelium. Nerve fibers containing vasoactive intestinal p

Importance of proximal hydrogen bonds in haem proteins.

We have used the density functional B3LYP method to study the effect of hydrogen bonds from the histidine ligand in various haem proteins to carboxyl groups or to the carbonyl backbone. Hydrogen bonds to carbonyl groups (encountered in globins and cytochromes, for example) have a small influence on the geometry and properties of the haem site. However, hydrogen bonds to a carboxyl group (encounter

Atrial fibrillation and its association with type 2 diabetes and hypertension in a Swedish community.

Aim: To explore the prevalence of atrial fibrillation in patients with hypertension and type 2 diabetes and to identify possible mechanisms for the development of atrial fibrillation. Methods: A community-based, cross-sectional observational study was conducted in the primary health care in Skara, Sweden, and 1739 subjects (798 men, 941 women) were surveyed. Patients were categorized as those wit

Practical scope recovery using bridge parsing

Interactive development environments (IDEs) increase programmer productivity, but unfortunately also the burden on language implementors since sophisticated tool support is expected even for small domain-specific languages. Our goal is to alleviate that burden, by generating IDEs from high-level language specifications using the JastAdd meta-compiler system. This puts increased tension on scope re

The diel activity of crucian carp, Carassius carassius, in relation to chemical cues from predators

Chemical cues from piscivorous fish and prey alarm substances often cause rapid fright responses in prey. However little is known of how piscivore-related chemical cues affect prey behaviour over periods longer than a few hours. Here we have investigated how chemical cues from piscivorous northern pike, Esox lucius, affect habitat choice and diel activity of crucian carp, Carassius carassius, over
