Evaluation of the tissue microarray technique for immunohistochemical analysis in rectal cancer.

BACKGROUND: Immunohistochemical staining for tumor-associated proteins is widely used for the identification of novel prognostic markers. Recently, a tissue-conserving, high-throughput technique, tissue microarray, has been introduced. This technique uses 0.6-mm tissue core biopsy specimens, 500 to 1000 of which are brought into a new paraffin array block, which can be sectioned up to 100 times. M

Serum levels of citalopram and its main metabolites in adolescent patients treated in a naturalistic clinical setting

The prescribing of selective serotonin reuptake inhibitors for adolescents is extensive despite the fact that there are few pharmacokinetic (PK), efficacy, safety, or tolerability studies on this group. This study reports the PK findings from two trials in adolescents treated with citalopram (CIT) in naturalistic clinical settings: one retrospective and one prospective. The aim of our study was to

Americanitis : Amerika som sjukdom eller läkemedel : Svenska berättelser om USA åren 1900-1939

Popular Abstract in SwedishAvhandlingen syftar till att studera svenska föreställningar om USA och det amerikanska och genom dem den svenska självbilden och olika visioner om den svenska framtiden i den offentliga debatten under perioden c:a 1900-1939, då USA var omdiskuterat som en mycket betydelsefull ny nation men ännu inte erkänt som en obestridlig supermakt. Den söker visa hur föreställningarThe aim of this thesis is to study Swedish notions of the USA and of things American and through them the Swedish self-image and the ideas about the Swedish future as seen in public debate in the period c. 1900-1939, when the USA was the subject of a good deal of discussion as an up-and-coming nation of great importance but was not yet recognized as an indisputable super power. It tries to demonst

Radiation effects on S-phase duration, labelling index, potential doubling time and DNA distribution in head and neck cancer xenografts

The effect of irradiation on S-phase duration (Ts), labelling index (LI), potential doubling time (Tpot), and cell cycle phase distributions was determined by DNA flow cytometry in xenografted human squamous cell carcinoma of the head and neck (SCCHN). Tumours were treated with a single dose of 3 Gy, and excised at intervals over a 90-h period. Six hours before each excision the tumours were label

Effect of cysteine mutations on direct electron transfer of horseradish peroxidase on gold

Surface exposed cysteines were genetically engineered in the structure of recombinant horseradish peroxidase (rHRP). Recombinant forms of HRP with either a His-tag or a Strep-tag at the C-terminus were produced, which additionally had cysteines at positions 57, 189 or 309 (C-terminus) of the polypeptide chain. An E coli expression system was exploited. The effect of these mutations on the direct e

End-stage renal disease and low level exposure to lead, cadmium and mercury; a population-based, prospective nested case-referent study in Sweden

Background: Cadmium (Cd), lead (Pb), and mercury (Hg) cause toxicological renal effects, but the clinical relevance at low-level exposures in general populations is unclear. The objective of this study is to assess the risk of developing end-stage renal disease in relation to Cd, Pb, and Hg exposure. Methods: A total of 118 cases who later in life developed end-stage renal disease, and 378 matched

DESIGN: Retrospective epidemiologic and clinical and molecular genetic observational study. METHODS: SETTING: National referral center. PARTICIPANTS: Forty-five individuals diagnosed with Best disease. OBSERVATION PROCEDURES: Retrospective review of patients diagnosed accordin

Biocompatibility of mannan nanogel-safe interaction with plasma proteins

Background: Self-assembled mannan nanogels are designed to provide a therapeutic or vaccine delivery platform based on the bioactive properties of mannan to target mannose receptor expressed on the surface of antigen-presenting cells, combined with the performance of nanogels as carriers of biologically active agents. Methods: Proteins in the corona around mannan nanogel formed in human plasma wer

Positive Surgical Margins in Radical Prostatectomy: Outlining the Problem and Its Long-Term Consequences

Context: This review focuses on positive surgical margins (PSM) in radical prostatectomy (RP). Objective: To address the etiology, incidence, and oncologic impact of PSM and discuss technical points to help surgeons minimize their positive margin rate. An evidence-based approach to assist clinicians in counseling patients with a PSM is provided. Evidence acquisition: A literature search in English

Comparison of fertility and seasonal effects on grassland microbial communities

The activity of saprotrophic fungi and bacteria, and the balance between them, can affect decomposition. Arbuscular mycorrhizal (AM) fungi are also important for the nutrient and energy transfer in soil. Microbial community composition and activity are believed to have seasonal patterns, and are known to be highly influenced by environmental factors such as pH and nutrient conditions. To evaluate

Quaternary of Norden

Nordic countries have experienced multiple glaciations and intervening interglacials during the last ca. 2.5-3 million years. Although evidence from Greenland and Iceland shows that ice sheets started to expand some time before 3 Ma, little is known about the glaciations and intervening interglacials older than the last Glacial Maximum due to repeated phases of glacial erosion and reworking. The e

Independent evolution of neurotoxin and flagellar genetic loci in proteolytic Clostridium botulinum

Background: Proteolytic Clostridium botulinum is the causative agent of botulism, a severe neuroparalytic illness. Given the severity of botulism, surprisingly little is known of the population structure, biology, phylogeny or evolution of C. botulinum. The recent determination of the genome sequence of C. botulinum has allowed comparative genomic indexing using a DNA microarray. Results: Whole ge

Urinary diversion after cystectomy for bladder cancer: A population-based study in Sweden

Objective. To investigate the type of urinary diversion performed after cystectomy in patients with muscle-invasive bladder cancer in Sweden, using data from a population-based national register. Material and methods. Since 1997, the Swedish Bladder Cancer Register has included more than 90% of all patients with newly diagnosed bladder cancer. The different types of urinary diversion performed in

Gestational age at birth and risk of allergic rhinitis in young adulthood

Background: Previous studies of the association between gestational age or birth weight and allergic rhinitis in later life have had various limitations, including the inability to estimate risk among subjects born extremely preterm or to examine specific contributions of gestational age and fetal growth. Objective: We sought to determine whether gestational age at birth independent of fetal growt

Great-Circle Migration Of Arctic Passerines

Birds can save distance and time on their migratory journeys by following great circles rather than rhumblines, but great-circle routes require more complex orientation with changing courses. Flight directions at different places along the route and in relation to the destination can be used to test whether birds migrate along great circles or rhumblines. Such data have indicated great-circle migr

Viewpoints of adults with and without Autism Spectrum Disorders on public transport

Background: Public transport is low cost, allows for independence, and facilitates engagement and participation for non-drivers. However, the viewpoints of individuals with cognitive disabilities are rarely considered. In Australia, the prevalence of Autism Spectrum Disorders (ASD) is approximately 1% and increasing. Many individuals with ASD do not possess a driver's licence, indicating that acce

Long-term exposure to air pollution and hospital admissions for ischemic stroke. A register-based case-control study using modelled NOx as exposure proxy

Background: Long-term exposure to air pollution is a hypothesized risk factor for ischemic stroke. In a large case-control study with a complete study base, we investigated whether hospital admissions for ischemic stroke were associated with residential concentrations of outdoor NOx, as a proxy for exposure to air pollution, in the region of Scania, Southern Sweden. Methods: We used a two-phase ca
