Levothyroxine treatment reduces thyroid size in children and adolescents with chronic autoimmune thyroiditis.

Context: The use of levothyroxine to reduce thyroid size in pediatric patients with goiter due to chronic autoimmune thyroiditis (AIT) remains controversial. In overtly hypothyroid patients, reductions in thyroid volume have been reported, whereas the effect in subclinically hypothyroid and euthyroid patients is less clear. Objective: The objective of the study was to evaluate the effect of levot

Tulasnein and podospirone from the coprophilous xylariaceous fungus Podosordaria tulasnei

Tulasnein (1), a new metabolite with strong antimicrobial and weaker cytotoxic and phytotoxic activity, was isolated from culture filtrates of three strains of the xylariaceous coprophilous fungus Podosordaria tulasnei. The producing strains were identified by their rhizomorphs and by ITS rDNA sequence analysis. A second new metabolite, podospirone (2), was also produced by all three strains where

Balanced partition of minimum spanning trees

To better handle situations where additional resources are available to carry out a task, many problems from the manufacturing industry involve dividing a task into a number of smaller tasks, while optimizing a specific objective function. In this paper we consider the problem of partitioning a given set S of n points in the plane into k subsets, S-1,...,S-k, such that max(1less than or equal toil

The establishment and utility of Sweha-Reg: a Swedish population-based registry to understand hereditary angioedema

ABSTRACT: BACKGROUND: The importance of acquiring comprehensive epidemiological and clinical data on hereditary angioedema has increasingly caught the attention of physicians and scientists around the world. The development of networks and creation of comprehensive policies to improve care of people suffering from rare diseases, such as hereditary angioedema, is a stated top priority of the Europe

Programmed cross flow asymmetrical flow field-flow fractionation for the size separation of pullulans and hydroxypropyl cellulose

Different functions for the programming of the cross flow in asymmetrical flow field-flow fractionation were studied with the aim to find the flow conditions most suitable for the molar mass distribution analysis of high molecular weight polysaccharides. A mixture of four differently sized pullulans covering the molar mass range 5.8 x 10(3)-1.6 x 106 g mol(-1) were used as a model sample. Two type

Urinary excretion of oligosaccharides induced by galactose given orally or intravenously

The effect of oral administration of galactose, lactose, and sucrose and intravenous injection of galactose on the urinary excretion of blood-group-active oligosaccharides has been studied. Galactose given either as the free sugar, a glycoside (lactose) or a constituent of normal diet was an absolute requirement for the formation and excretion of A-trisaccharide, B-trisaccharide and 2'-fucosylgala

Brandteknisk dimensionering med riskbaserade ekvationer

The aim of this study was to derive simple risk-based equations to be used in fire safety design. Design values for the equations are derived from a specific target risk, usually described as the target reliability index β. Using the design values with accepted calculation methods would result in an accepted engineering solution to the problem. This approach is commonly used in structural engineer

Cost of illness of adult diabetes mellitus underestimated if comorbidity is not considered

OBJECTIVE: To determine costs of illness for adult diabetes mellitus (DM), including complications caused by DM. DESIGN: A population-based multicentre cross- sectional study including an interview and a physical examination of patients identified as having DM. The patients' medical records were analysed regarding diagnoses and complications attributable to DM. SETTING: Eight health care centres o

Gravitational scattering in the ADD model revisited

It is argued that the assumption that the standard model particles live on a finite brane in the ADD model does in itself imply a finite propagator for virtual Kaluza-Klein mode exchange. The part of the propagator relevant for large distance scattering is cut-off-independent for scattering at distances large compared to the brane width. The matrix element corresponding to this part can also, at l

Nicotinamide as a repair inhibitor in vivo: studies using single and fractionated X-ray doses in mouse skin and kidneys

Inhibitors of adenosine diphosphoribosyl transferase, like nicotinamide, 3-aminobenzamide and other analogues, can inhibit repair of radiation-induced sublethal and/or potentially lethal damage in some in vitro systems. Therefore, we have tested the effect of nicotinamide on repair parameters in vivo in two rodent normal tissues. In skin, the sensitivity to dose fractionation (1, 2, 5 or 10 X-ray

Combining matrix elements and the dipole cascade model

An algorithm is presented in which the Colour-Dipole Cascade Model as implemented in the ARIADNE program is corrected to match the fixed order tree-level matrix elements for e(+)e(-) --> n jets. For the results presented here, matrix elements were used up to second order in alpha(S) but the scheme is applicable also for higher orders.

3-Hydroxypropionic acid as a nematicidal principle in endophytic fungi

3-Hydroxypropionic acid was isolated by bioactivity-guided fractionation of extracts obtained from submerged cultures of several endophytic fungi isolated from above-ground plant organs. This compound showed selective nematicidal activity against the plant-parasitic nematode Meloidogyne incognita with LD50 values of 12.5-15 mug/ml. Activity against the saprophytic Caenorhabditis elegans was fivefo
