OBJECTIVES: A combination of surgical and medical approaches may address both the underlying pathophysiological processes and the most threatening symptoms in twin-twin transfusion syndrome (TTTS). CASE: A primigravida with monochorionic twin pregnancy was referred with signs of TTTS at 16 weeks. One twin was severely hydropic with normal amniotic fluid, the co-twin had anhydramnios. Laser treatme

Magnetic compass orientation in birds has been shown to be light dependent. Results from behavioural studies indicate that magnetoreception capabilities are disrupted under light of peak wavelengths longer than 565 nm, and shifts in orientation have been observed at higher light intensities (43-44x1015 quanta s-1 m-2). To investigate further the function of the avian magnetic compass with respect

Marine-lacustrine isolation contacts from seven basins in the Nanortalik area, South Greenland have been analysed and dated. The basins were isolated from the sea as a consequence of isostatic rebound following deglaciation. The isolation contacts were identified with litho- and biostratigraphical analyses, especially sedimentary changes, grey scale analyses and analyses of macroscopical remains o

Objective: The therapies available today for multiple sclerosis (MS) reduce but do not fully control disease activity. The objective of this article is to review the definitions of and treatments for suboptimally controlled MS and highlight the challenges faced by clinicians to increase awareness of recognizing and managing patients with suboptimally controlled MS. Methods: Published literature de

Conventional lipomas harbor karyotypic changes that could be subdivided into four, usually mutually exclusive, categories: rearrangement, in particular through translocations, of chromosome bands 12q13-15, resulting in deregulation of the HMGA2 gene, loss of material from or rearrangement of chromosome 13, supernumerary ring or giant marker chromosomes, and aberrations of chromosome band 6p21. In

To investigate a possible time trend in serum concentrations of persistent organochlorine pollutants (POPs), representative samples of the young (median age 18 years) Swedish male population were investigated in the years 2000 and 2004. Due to their low age, these men were assumed not to have reached steady state of body burdens of POPs, why their serum concentrations were considered to represent

A portfolio assessment system has been introduced into a biomedical science programme to promote both continuous learning and deep approaches to learning. Attention has been focused on creating harmony between the assessment system and the PBL curriculum of the programme. Biomedicine and laboratory work are central in the curriculum. The portfolio included evidence of laboratory work, personal ref

The calcipotriol/betamethasone dipropionate two-compound product Dovobet (R)/Daivobet (R)/Taclonex (R)(LEO Pharma A/S, Ballerup, Denmark) has been shown to be safe and effective in the treatment of psoriasis for up to 8 weeks. As psoriasis is a chronic disease, long-term treatment may be required, so there is a need to investigate the safety of its use over a longer period of time. To investigate

Intranasal immunization of mice with Rib, a cell surface protein of group B streptococcus (GBS), conjugated to or simply coadministered with the recombinant cholera toxin B subunit, induces systemic immunoglobulin G (IgG) and local IgA antibody responses and confers protection against lethal GBS infection. These findings have implications for the development of a human GBS vaccine.

Axillary dermatitis is a common problem, particularly in individuals with contact allergy to fragrances. Many individuals suspect their deodorant to be the causal product of their fragrance allergy. It has been shown that deodorants containing cinnamic aldehyde (cinnamal) can elicit axillary dermatitis in patients sensitized to this substance. The aim of the present investigation was to evaluate t

Models of several types of iron-sulfur clusters (e.g., Fe4S4(SCH3)42-/3-/4-) have been studied with the density functional B3LYP method and medium-sized basis sets. In a vacuum, the inner-sphere reorganization energies are 40, 76, 40, 62, 43, and 42 kJ/mol for the rubredoxin, [2Fe-2S] ferredoxin, Rieske, [4Fe-4S] ferredoxin, high-potential iron protein, and desulfoferrodoxin models, respectively.

Mycorrhizal symbioses -- the union of roots and soil fungi -- are universal in terrestrial ecosystems and may have been fundamental to land colonization by plants1,2. Boreal, temperate, and montane forests all depend upon ectomycorrhizae1. Identification of the primary factors that regulate symbiotic development and metabolic activity will therefore open the door to understanding the role of 2 ect

In the present study, we have generated a mutant strain of Streptococcus pyogenes, MC25, which lacks M protein on its surface, and we demonstrate that this strain is unable to generate a mature 28 kDa cysteine proteinase. Furthermore, we show that S. pyogenes bacteria of M1 serotype are dependent on cell wall-anchored M protein to cleave the secreted zymogen into a mature cysteine proteinase. We a

By correlating literary evidence, avian ethology and neurophysiology I will try to demonstrate why Valmiki chose a pair of Sarus Cranes, and not any other avian species, to epitomise grief and sorrow in the Ramayana. This choice illustrates the importance of personal experience of the living reality (behaviour of Sarus Cranes); but the grief, soka, as experienced by Valmiki, became in later critic

Luminescent materials have been utilized widely in applications from lighting to sensing. The new development of technologies based on luminescence requires the materials to have high luminescence efficiency and mechanical strength. In this paper, we report the fabrication of luminescent materials possessing high mechanical strength by nanofabrication with polyvinyl alcohol used as a stabilizer or

This article reports results from a long-term follow-up of adolescents with conduct disorder who have been patients at an inpatient child psychiatric unit in Lund, Sweden. Up to now, a total of 186 adolescents have participated in the follow-up study. The subjects are a heavily symptom-loaded group with many problems during their childhood. The study includes self-rating that describe psychiatric
