Quality control of MHC class I maturation

Assembly of MHC class I molecules in the ER is regulated by the so-called loading complex (LC). This multiprotein complex is of definite importance for class I maturation, but its exact organization and order of assembly are not known. Evidence implies that the quality of peptides loaded onto class I molecules is controlled at multiple stages during MHC class I assembly. We recently found that tap

Effects of whey proteins on glycaemia and insulinaemia to an oral glucose load in healthy adults; a dose-response study.

Background/Objectives:Whey proteins have insulinogenic properties and the effect appears to be mediated from a postprandial plasma amino-acid (AA) response. The aim was to study the possible dose-response relationship between whey intake and glycaemic-, insulinaemic- and plasma AA responses.Subjects/Methods:Twelve healthy volunteers participated in the study. They were provided three whey protein

Search for strong production of supersymmetric particles in final states with missing transverse momentum and at least three b-jets at root s=8 TeV proton-proton collisions with the ATLAS detector

This paper reports the results of a search for strong production of supersymmetric particles in 20.1 fb(-1) of proton-proton collisions at a centre-of-mass energy of 8 TeV using the ATLAS detector at the LHC. The search is performed separately in events with either zero or at least one high-p (T) lepton (electron or muon), large missing transverse momentum, high jet multiplicity and at least three

Randomized trial of single agent paclitaxel given weekly versus every three weeks and with peroral versus intravenous steroid premedication to patients with ovarian cancer previously treated with platinum

The aim of this study was to evaluate the efficacy and toxicity of paclitaxel given at the same dose intensity and administered weekly (arm A) or every 3 weeks (arm B), and to assess the safety of intravenous steroids versus standard peroral premedication. Two hundred and eight patients with advanced ovarian cancer previously treated with no more than one platinum-containing regimen were randomize

Leisure activities in rheumatoid arthritis: Change after disease onset and associated factors

The objective of this investigation was to examine the relationship between leisure-time occupations, quality of life disease activity among patientswith rheumatoid arthritis. Fifty patients with rheumatoid arthritis-39 females and 11 males, age 30-45 years and belonging to functional class I-III according to Steinbrocker er al (1949)-were recuited from the register at a hospital clinic and from a

Exercise-induced rib stress fractures: influence of reduced bone mineral density

Exercise-induced rib stress fractures have been reported frequently in elite rowers during the past decade. The etiology of rib stress fractures is unclear, but low bone mineral density (BMD) has been suggested to be a potential risk factor for stress fractures in weight-bearing bones. The present study investigated BMD in seven Danish national team rowers with previous rib stress fracture (RSF) a

Management of pregnancies with suspected intrauterine growth retardation in Sweden. Results of a questionnaire

BACKGROUND: Diagnosis and management of intrauterine growth retardation during pregnancy remain a major challenge in obstetric care. The objective of this survey was to evaluate the routine clinical management of pregnancies with suspected intrauterine growth retardation at obstetric departments in Sweden. METHODS: In 1997, a questionnaire was sent to all 59 obstetric departments in Sweden. Forty-

Radiative lifetimes in Ce I and Ce II

New radiative lifetime measurements based on time-resolved laser-induced fluorescence techniques are reported for 18 even-parity levels belonging to the 4f5d(2)6p and 4f(2)5d(2) configurations of Ce I and 6 even-parity levels belonging to the 5d(2)6s, 4f5d6p, and 4f6s6p configurations of Ce II. Free neutral and singly ionized cerium atoms were produced by laser ablation. The Ce I and Ce II levels

Drug-related problems in the elderly - Interventions to improve the quality of pharmacotherapy

Popular Abstract in Swedish Läkemedelsrelaterade problem hos äldre - Interventioner för att förbättra läkemedelsbehandlingen Läkare inom primärvården står för en stor del av den totala läkemedelsförskrivningen i Sverige och är en viktig målgrupp för läkemedelsindustrins information. Det har i flera uppmärksammade studier från Socialstyrelsen uppmärksammats att läkemedelsbehandlingen för patientIntroduction: Elderly people, in particular those residing in nursing homes, often use many drugs. In general elderly patients are at greater risk of experiencing drug-related problems (DRP), as they have multiple diseases, are using many drugs and have changed physiological status. Objectives: To describe the frequency of potential drug-related problems in the elderly and to evaluate different k

Study of inclusive J/psi production in two-photon collisions at LEP II with the DELPHI detector

Inclusive J/psi production in photon-photon collisions has been observed at LEP II beam energies. A clear signal from the reaction gammagamma --> J/psi + X is seen. The number of observed N(J/psi --> mu(+)mu(-)) events is 36+/-7 for an integrated luminosity of 617 pb(-1), yielding a cross-section of sigma(J/psi + X) = 45+/-9(stat) +/- 17(syst) pb. Based on a study of the event shapes of different

Gas Diffusion Through Sheets of Fibrous Porous Media

Using a cell model to describe a fibrous porous medium theoretical expressions ale deduced relating effective gas diffusivity to the volume fraction of the fibres. Cylindrical as well as band-shaped fibres are studied. The new models, which are based on solutions to the diffusion equation, agree well with existing correlations. The models are compared with experimental data for water vapour diffus

Ecological diversification in habitat use in subtidal triplefin fishes (Tripterygiidae)

Recent work has shown that habitat specialisation can lead to diversification in lacustrine and marine fish species. Here we investigate specialisation in the New Zealand triplefin fish fauna (Tripterygiidae), which has the greatest diversity and disparity of triplefin species in the world with 26 endemic species. Most species are sympatric throughout coastal New Zealand, showing no obvious latitu

Bone mineral density in patients with Crohn's disease during long-term treatment with azathioprine

OBJECTIVES: To ascertain whether patients with Crohn's disease treated with azathioprine maintained bone mineral mass better than patients treated with steroids alone. DESIGN: Retrospective study. SETTING: University Hospital of Malmo, Sweden. SUBJECTS: A total of 59 patients with ileocolonic, ileocaecal or colonic Crohn's disease. METHODS: Bone mass was assessed by dual photon X-ray absorptiometr
