Parallel post-source decay for increasing protein identification confidence levels from 2D gels
Peptide mass fingerprinting (PMF) has over the years become one of the most commonly used tools for high-throughput analysis and identification of proteins. This method is applicable when relatively simple samples have to be analysed and it is commonly used for analysing proteins previously separated by 2-DE. The most common type of instrument used for this approach is the MALDI-TOF that has prove
Histopathological risk factors for ipsilateral breast events after breast conserving treatment for ductal carcinoma in situ of the breast - Results from the Swedish randomised trial.
Aim: The primary aims were to study risk factors for an ipsilateral breast event (IBE) after sector resection for ductal carcinoma in situ of the breast (DCIS) in a trial comparing adjuvant radiotherapy to no therapy and to assess predictive factors for response to radiotherapy Secondary aims were to analyse reproducibility of the histopathological evaluation and to estimate correctness of diagnos
Swedish moist snuff accelerates gastric cancer development in Helicobacter pylori-infected wild-type and gastrin transgenic mice
The Swedish variant of moist oral smokeless tobacco (snus) is popular in Sweden and Norway, banned from sale within the European Union and is currently being introduced in USA. The aim of the present study was to determine if snus is carcinogenic to the stomach, particularly in Helicobacter pylori (H.P.)-infected hosts at increased risk for gastric cancer development. Snus (General (TM); Swedish M
The effect of increased apparatus dead space and tidal volumes on carbon dioxide elimination and oxygen saturations in a low-flow anesthesia system.
STUDY OBJECTIVE: To determine if a large tidal volume (V(T)), with an unchanged end-tidal carbon dioxide partial pressure (P(ET)co(2)), could improve arterial carbon dioxide elimination, oxygen saturation (Spo(2)), and arterial blood oxygenation. DESIGN: Prospective, randomized, clinical study. SETTING: Single university hospital. PATIENTS: 60 ASA physical status I and II patients scheduled for el
The reliability and validity of the locognosia test after injuries to peripheral nerves in the hand
Locognosia, the ability to localise touch, is one aspect of tactile spatial discrimination which relies on the integrity of peripheral end-organs as well as the somatosensory representation of the surface of the body in the brain. The test presented here is a standardised assessment which uses a protocol for testing locognosia in the zones of the hand supplied by the median and/or ulnar nerves. Th
Persistent itching nodules after the fourth dose of diphtheria-tetanus toxoid vaccines without evidence of delayed hypersensitivity to aluminium
Studies in Gothenburg, Sweden, reported an exceptionally high rate of persistent itching nodules at the site of injection of aluminium containing vaccines, usually with positive epicutaneous tests to aluminium. When a new booster diphtheria-tetanus vaccine was introduced we performed a prospective cluster randomised active surveillance in 25,232 10-year-olds. Parental reports 6 months after vaccin
Prescriptions with potential drug interactions dispensed at Swedish pharmacies in January 1999: cross sectional study
The growing use of pharmacological agents means that drug interactions are of increasing interest for public health.1 Monitoring of potential drug interactions may improve the quality of drug prescribing and dispensing, and it might form a basis for education focused on appropriate prescribing.
Diversities and similarities in PFGE profiles of Campylobacter jejuni isolated from migrating birds and humans
Aims: To genetically sub-type Campylobacter jejuni strains isolated from migratory birds, and to compare these with clinical strains collected in the same area and corresponding time period, with the aim to increase our knowledge on sub-types occurring among wild birds and their possible impact on human disease. Methods and Results: We sub-typed C. jejuni strains from migrating birds (n = 89) and
Seasonal cycles of isotopic abundances of 18-O/16-O, 13-C/12-C, and D/H in ozone, methane and water vapor, derived from ground-based arctic FTIR measurements
Intrinsically proton-conducting comb-like copolymers with benzimidazole tethered to the side chains
Intrinsically proton-conducting comb-like copolymers having side chains tethered with benzimidazole units have been prepared and characterized with respect to their thermal properties and proton conductivity. In the first step of the preparation, poly(4-hydroxystyrene) was synthesized by polymerization of tert-butoxystyrene followed by hydrolysis of the butoxy groups. In the next step, poly(allyl
Uptake, translocation and assimilation of nitrogen from 15N-labeled ammonium and nitrate sources by intact ectomycorrhizal systems of Fagus sylvatica infected with Paxillus involutus
The uptake and assimilation of nitrogen from 15N-labelled ammonium and nitrate sources was followed in intact ectomycorrhizal systems containing Fagus sylvatica L. plants infected with the fungus Paxillus involutus (Mich. ex Pers.) Cohen & Couch. Plants were grown in flat perspex observation chambers containing non-sterile peat; the fungal mycelium growing from a host plant was allowed to cros
Assessment of organochlorine pesticide pollution in Upper Awash Ethiopian state farm soils using selective pressurised liquid extraction.
Upper Awash Agro Industry Enterprises (UAAIE) is one of the major state farms in Ethiopia with known large-scale pesticide use. Although organochlorine pesticides (OCPs) have been applied for about three decades, no studies have been carried out on levels of residue in the region. In this work a fast selective pressurised liquid extraction (SPLE) methodology has successfully been applied for scree

The social networks of severely mentally ill persons in inpatient settings and sheltered community settings
The social networks of individuals with severe mental illness admitted to long-term in-patient settings and living in two types of supported housing, small congregate community residences and independent living with support, were compared. The Interview Schedule for Social Interaction (ISSI) was used. The results showed no substantial differences in social networks between the two types of support

Adaptation of soil microbial communities to temperature: comparison of fungi and bacteria in a laboratory experiment
Temperature not only has direct effects on microbial activity, but can also affect activity indirectly by changing the temperature dependency of the community. This would result in communities performing better over time in response to increased temperatures. We have for the first time studied the effect of soil temperature (5-50 degrees C) on the community adaptation of both bacterial (leucine in

The role of gastric evacuation rate in handling time of equal-mass rations of different prey sizes in northern pike
In a laboratory experiment, northern pike Esox lucius gastric evacuation rates did not differ between equal-mass rations of small and large prey. In a comparison between intermediate and large prey, the pike were unable to fit two intermediate prey completely into the stomach at the same time, resulting in two consecutive evacuations, and changes in patterns of gastric evacuation. Thus. total gast
