Heparin-binding protein: an early marker of circulatory failure in sepsis.

BACKGROUND: The early detection of circulatory failure in patients with sepsis is important for successful treatment. Heparin-binding protein (HBP), released from activated neutrophils, is a potent inducer of vascular leakage. In this study, we investigated whether plasma levels of HBP could be used as an early diagnostic marker for severe sepsis with hypotension. METHODS: A prospective study of 2

Factors with independent influence on the 'timed up and go' test in patients with hip fracture.

Background and Purpose. Data on performance times for the 'timed up and go' (TUG) test with analyses of factors, that eventually could affect the result in patients with hip fracture, have not been published to date. The aims of the present study, therefore, were to assess normative reference values of TUG performances and determine the influence of individual and clinical factors on TUG-test scor

A survey of spinal collateral actions of feline ventral spinocerebellar tract neurons.

The aim of this study was to identify spinal target cells of spinocerebellar neurons, in particular the ventral spinocerebellar tract (VSCT) neurons, giving off axon collaterals terminating within the lumbosacral enlargement. Axons of spinocerebellar neurons were stimulated within the cerebellum while searching for most direct synaptic actions on intracellularly recorded hindlimb motoneurons and i

Multiple pregnancy failures: an immunological paradigm.

Recurrent spontaneous abortion (RSA), three or more pregnancy losses prior to 20 weeks, occurs in about 1% of all pregnancies, 50% of RSA cases remain unexplained and unresolved. Recently, immune pathways have been implicated in the pathophysiology of RSA. Immune tolerance of the fetal-placental unit and placental angiogenesis are mandatory for a successful pregnancy outcome. Unscheduled dysregula

Novel insertions of Bruton tyrosine kinase in patients with X-linked agammaglobulinemia.

Mutations in the gene encoding Bruton tyrosine kinase (BTK) result in X-linked agammaglobulinemia (XLA), an immunodeficiency of antibody defect. By using base excision sequence scanning method (BESS) followed by direct sequencing we found in seven unrelated families with a classical XLA phenotype various mutations including six novel mutations (g.64512_64513insC, c.108_109insG, c.1700_1701insACTAC

Large-scale Multiconfiguration Hartree-fock Calculations of Hyperfine-interaction Constants For Low-lying States In Beryllium, Boron, and Carbon

Multiconfiguration Hartree-Fock (MCHF) calculations of hyperfine constants for the 2s2p 3P states of beryllium and the ground states of boron and carbon are reported. The capacity of a recently developed configuration-interaction program [Froese Fischer and Tong (unpublished); Stathopoulos and Froese Fischer (unpublished)], allowing for large configuration expansions, is explored. Using a systemat

Laparoscopic aided cholecystostomy as a treatment of inspissated bile syndrome.

We report a case of a newborn girl with inspissated bile syndrome (IBS) that did not respond to treatment with oral ursodeoxycholic acid (Ursofalk). A solution was found using laparoscopic aided cholecystostomy with an indwelling catheter for local Ursofalk flushing in the gallbladder and the choledochus. This is the first report of a laparoscopic aided management of IBS without cholecystectomy or

Solute transport on the sub 100 ms scale across the lipid bilayer membrane of individual proteoliposomes

Screening assays designed to probe ligand and drug-candidate regulation of membrane proteins responsible for ion-translocation across the cell membrane are wide spread, while efficient means to screen membrane-protein facilitated transport of uncharged solutes are sparse. We report on a microfluidic-based system to monitor transport of uncharged solutes across the membrane of multiple (>100) indiv

EASI-Derived vs standard 12-lead electrocardiogram for Selvester QRS score estimations of chronic myocardial infarct size, using cardiac magnetic resonance imaging as gold standard.

BACKGROUND: The size of myocardial infarction (MI) is of significance for the prognosis. Selvester scores might be valuable for this estimation. OBJECTIVE: To compare the differences in Selvester scores for chronic MI provided from standard and EASI-derived 12-lead electrocardiograms (ECGs) and to compare these scores to the MI size measured by delayed-enhancement magnetic resonance imaging (DE-MR

Contrast media as markers of GFR

Determination of the glomerular filtration rate (GFR) is generally considered as the most important parameter of quantifying renal function. The GFR is determined as renal or plasma clearance of an ideal filtration marker which is freely filtered by the kidney, does not undergo metabolism, tubular secretion or absorption. Markers that fulfil these demands are inulin, 51Cr-EDTA, 99mTc-DTPA, labelle

Generation of trisomies in cancer cells by multipolar mitosis and incomplete cytokinesis.

One extra chromosome copy (i.e., trisomy) is the most common type of chromosome aberration in cancer cells. The mechanisms behind the generation of trisomies in tumor cells are largely unknown, although it has been suggested that dysfunction of the spindle assembly checkpoint (SAC) leads to an accumulation of trisomies through failure to correctly segregate sister chromatids in successive cell div

Tree species composition in European pristine forests

The degree of general applicability across Europe currently achieved with several forest succession models is assessed, data needs and steps for further model development are identified and the role physiology based models can play in this process is evaluated. To this end, six forest succession models (DISCFORM, ForClim, FORSKA-M, GUESS, PICUS v1.2, SIERRA) are applied to simulate stand structure

Internet-based assessment of medical students' ophthalmoscopy skills.

Abstract. Purpose: Ophthalmoscopy is an important skill in undergraduate medical education. The use and outcome of a novel Internet-based method for assessing motor skills-related aspects of ophthalmoscopy skills in medical students are described. Methods: A total of 139 students in Malmö and 255 students in Umeå were assessed during four consecutive semesters. An optic disc photograph was obtaine

Risk of recurrence following delayed large flap reconstruction after mastectomy for breast cancer.

BACKGROUND: The aim of this retrospective matched cohort study was to evaluate the rate of recurrence among women with delayed large flap breast reconstruction after mastectomy for breast cancer. The recurrence rate among women treated at a single hospital was compared with that in an individually matched control group of women with breast cancer who did not have reconstruction after mastectomy. M

On user effects in MIMO handset antennas designed using characteristic modes

The Theory of Characteristic Modes (TCM) has been applied to design high-performance MIMO antennas for mobile terminals. However, existing studies focus on free-space (FS) performance, which is mostly irrelevant in real usage. This paper investigates the performances of two TCM-based MIMO terminal antenna designs in 7 realistic user scenarios for frequencies below 1 GHz. Full-wave simulation resul

Risk of incident and fatal melanoma in individuals with a family history of incident or fatal melanoma or any cancer.

Background: A family history of melanoma is associated with an increased risk of melanoma and probably of other, discordant cancers. Limited data are available on familial mortality in melanoma. If fatal forms of melanoma were associated with fatal forms of melanoma or of some other cancers, only studies on familial mortality rather than on familial incidence might be able to detect them.
