The increasing microbial antibiotic resistance motivates research for non-antibiotic treatment alternatives. In recurrent urinary tract infections (UTIs), 'bacterial interference' has attracted interest as a possible alternative treatment option. The observation that asymptomatic bacteriuria (ABU) protects against recurrent UTI has prompted clinical trials with deliberate colonization of the human

In a field irradiation experiment UV-B radiation was enhanced to simulate 15% ozone depletion under clear sky conditions in northern Sweden. This was accomplished by using UV-B fluorescent lamps mounted on metal frames raised over a naturally growing plant community. 2. The study area consisted of a dwarf shrub heath mainly composed of the four species Vaccinium vitis-idaea, V. myrtillus, V. uligi

Liver is one of the most important organs in energy metabolism. Most plasma apolipoproteins and endogenous lipids and lipoproteins are synthesized in the liver. It depends on the integrity of liver cellular function, which ensures homeostasis of lipid and lipoprotein metabolism. When liver cancer occurs, these processes are impaired and the plasma lipid and lipoprotein patterns may be changed. Liv

In order to assess the non-evaporative components of the reduced thermal insulation of wet clothing, experiments were performed with a manikin and with human subjects in which two layers of underwear separated by an impermeable barrier were worn under an impermeable overgarment at 20 °C, 80% RH and 0.5 ms-1 air velocity. By comparing manikin measurements with dry and wetted mid underwear layer, th

Fourteen adult Fischer 344 rats were inoculated in vivo unilaterally in the caudate nucleus in the brain with malignant RG 2 glioma cells. By 3 weeks a tumor with a diameter of 3-6 mm normally develops. Ten animals which survived the repeated periods of anesthesia and thallium (Tl) injections (intratumorally three times of 201Tl, 15-23 days after inoculation) showed a prolonged retention of radioa

To elucidate how diabetic patients with limb-threatening foot lesions perceive and evaluate content and organisation of treatment in a multi-place hyperbaric oxygen chamber. To our knowledge there are no patients' evaluations of diabetes care in a high-technology area like the hyperbaric oxygen chamber. The burden on persons with diabetic foot complications might be increased if adjuvant therapy w

Two species within the Delia cardui species group were known to have males with the abdominal sternite III bipartite or very deeply incised, viz., D. bipartita Suwa from Japan and China and D. polaris Griffiths from extreme northern and high-altitude sites in North America. Two new species with this extraordinary character are described from northern Europe: D. rimiventris sp. nov. from southern N

Many lines of evidence implicate mitochondria in phenotypic variation: ( a) rare mutations in mitochondrial proteins cause metabolic, neurological, and muscular disorders; ( b) alterations in oxidative phosphorylation are characteristic of type 2 diabetes, Parkinson disease, Huntington disease, and other diseases; and ( c) common missense variants in the mitochondrial genome ( mtDNA) have been imp

During the last 10 years, we have cytogenetically analyzed at diagnosis bone marrow cells from a total of 94 children with acute leukemia. Of the 78 children with acute lymphatic leukemia (ALL), 53 (68%) had clonal acquired chromosome abnormalities; in the group with acute nonlymphatic leukemia (ANLL), the corresponding proportion was 13 out of 16 (81%). Among the cytogenetically abnormal ALL pati

Bone marrow-derived multipotent mesenchymal stroma cells (MSCs) have emerged as cellular vectors for gene therapy of solid cancers. We implanted enhanced green fluorescent protein-expressing rat MSCs directly into rat malignant gliomas to address their migratory capacity, phenotype, and effects on tumor neovascularization and animal survival. A single intratumoral injection of MSCs infiltrated the

PURPOSE: To assess how patients perceive health-related quality of life (HRQOL) after endovascular and open abdominal aortic aneurysm (AAA) repair. METHODS: Forty-two consecutive patients (33 men; mean age 74 years, range 46-81) were assessed prospectively before and after elective endovascular (n = 21) and open (n = 21) AAA repair. Aneurysm morphology dictated the type of repair. The two patient

OBJECTIVE. The aim of the study was to describe the association between clinical risk factors in diabetic patients with food ulcers in relation to outcome. DESIGN. A prospective study of 314 consecutively presenting diabetic patients with foot ulcers referred to the Department of Internal Medicine between July 1, 1983 and June 30, 1987. All patients were followed to final outcome. SETTING. All pat

This review discusses actual and potential contributors to functional improvement after stroke injuries. Topics that will be covered are neuronal re-organization and sprouting, neural stem/progenitor cell,activation and neuronal replacement, as well as the neuronal milieu defined by glia, inflammatory cells and blood vessel supply. It is well established that different types of neuronal plasticity

A compact model for evaluation of acid flushing of heavy-metal-contaminated soil in a small-scale on-site treatment plant is proposed. The model assumes that the soil was re-packed in a container after excavation resulting in a soil structure with heterogeneous and random physical and chemical properties. To evaluate the effects of heterogeneity on the efficiency of contaminant removal by acid flu

Objective. Hemophilic arthropathy, with characteristics of inflammatory (rheumatoid arthritis) and degenerative (osteoarthritis) joint damage, occurs at an early age, is associated with minor comorbidity, and is restricted to 3 pairs of large joints. The aim of this study was to determine whether commonly used serum and/or urinary biomarkers of cartilage and bone turnover for which assay kits are

While the persistence of socioeconomic differences in cardiovascular disease (CVD) has been recognized for many years, less is known about whether socioeconomic factors are of importance to CVD before symptoms of the disease appear. In this study the associations among educational level, occupational status and progression of atherosclerosis were investigated in 1016 Swedish middle-aged men and wo

Major depression is often associated with elevated glucocorticoid levels. High levels of glucocorticoids reduce neurogenesis in the adult rat hippocampus. Electroconvulsive seizures (ECS) can enhance neurogenesis, and we investigated the effects of ECS in rats where glucocorticoid levels were elevated in order to mimic conditions seen in depression. Rats given injections of corticosterone or vehic
