Cereal beta-glucans: use in foods to improve functionality and health.

The EU beta-glucan project is discussed together with the important diet related health issues, coronary heart disease and diabetes. Aspects considered include: effects of life-style and diet on the development of disease; the ability of cereal beta-glucans to lower plasma lipid levels and improve glucose tolerence; characteristics of beta-glucans; beta-glucans preparation and characterization; de

Nonparametric estimation of mixing densities for discrete distributions

By a mixture density is meant a density of the form pi(mu) (.) = f pi(theta) (.) x mu(d theta), where (pi(theta))(theta Theta is an element of) is a family of probability densities and mu is a probability measure on Theta. We consider the problem of identifying the unknown part of this model, the mixing distribution A, from a finite sample of independent observations from pi(mu). Assuming that the

The dUTPases from herpes simplex virus type 1 and mouse mammary tumour virus are less specific than the Escherichia coli enzyme

The enzyme dUTPase catalyses the hydrolysis of dUTP to dUMP and pyrophosphate, thereby suppressing incorporation of uracil into DNA and providing a pool of dUMP, the precursor of dTTP. Hydrolysis of other nucleotides similar in structure to dUTP would conceivably be physiologically detrimental and high specificity of the reaction seems to be necessary. In this work, we characterize the substrate s

Recursive estimation in mixture models with Markov regime

A recursive algorithm is proposed for estimation of parameters in mixture models, where the observations are governed by a hidden Markov chain. The performance of the algorithm is studied by simulations of a symmetric normal mixture. The algorithm seems to be stable and produce approximately normally distributed estimates, provided the adaptive matrix is kept well conditioned.

Säsongslagring i bergrum : utvärdering av värmeförluster Lyckebo Uppsala

Utvärderingen av Lyckebo solvärmeanläggnng med säsongslagring i öppet bergrum avslutades den 1 juli 1986. De värmeförluster som då konstaterades föranledde den uppföljning som denna rapport redovisar. Man försöker klarlägga orsakerna till avvikelser mellan beräknade och uppmätta värmeförluster och dra slutsatser för framtida projekt.

DNA ploidy analysis in breast carcinoma. Comparison of unfixed and fixed tissue analyzed by image and flow cytometry

OBJECTIVE: To form a methodologic basis for DNA analysis of ductal carcinoma in situ (DCIS) and invasive carcinoma (IC) of the breast, including very small lesions, by comparison of flow cytometric (FCM) and image cytometric (ICM) methods for DNA quantitation. STUDY DESIGN: The material consisted of 41 DCIS lesions and 26 ICs. FCM DNA analysis of unfixed, frozen samples were compared to (1) FCM of

Nodule detection in digital chest radiography: Introduction to the radius chest trial

Most digital radiographic systems of today have wide latitude and are hence able to provide images with a small constraint on dose level. This opens up for an unprejudiced dose optimisation. However, in order to succeed in the optimisation task, good knowledge of the imaging and detection processes is needed. As a part of the European-wide research project 'unification of physical and clinical req

Älskad och förnekad : Flickboken i Sverige 1945-65

The tradition of writing books specifically for girls came to an abrupt end in the middle of the 1960's. In Sweden this was a turbulent decade when society changed in many ways, and equality between the sexes was a key word. The old girls' and boys' books were replaced by "the modern book for young people", which, it was proclaimed, should be up-to-date, discuss real problems, break taboos, and ap

Oral contraceptives and the risk of breast cancer in BRCA1 and BRCA2 mutation carriers

Background: Oral contraceptive use has been associated with an increase in the risk of breast cancer in young women. We examined whether this association is seen in women at high risk of breast cancer because they carry a mutation in one of two breast cancer susceptibility genes, BRCA1 and BRCA2. Methods: We performed a matched case-control study on 1311 pairs of women with known deleterious BRCA1

Virtual reality therapy versus cognitive behavior therapy for social phobia: A preliminary controlled study

Social phobia is one of the most frequent mental disorders and is accessible to two forms of scientifically validated treatments: anti-depressant drugs and cognitive behavior therapies (CBT). In this last case, graded exposure to feared social situations is one of the fundamental therapeutic ingredients. Virtual reality technologies are an interesting alternative to the standard exposure in social

IgG glycan hydrolysis by EndoS diminishes the pro-inflammatory properties of immune complexes from patients with SLE - a possible new treatment?

OBJECTIVE.: Systemic lupus erythematosus (SLE) is an autoimmune disease with chronic or episodic inflammation in several organ systems, related to the presence of circulating and tissue-deposited immune complexes (ICs) which stimulate leukocytes through FcγRs with subsequent inflammation. Treatment with EndoS, an IgG glycan hydrolyzing bacterial enzyme from Streptococcus pyogenes, has shown benefi

Seasonal affective disorder: a clinical update.

BACKGROUND: Seasonal affective disorder (SAD) consists of recurrent major depressive episodes in the fall/winter with remissions in spring/summer. METHOD: A Medline search was conducted to identify studies relating to clinical management of SAD using the Medical Subject Heading, seasonal affective disorder, and key words, depress* and season*, focusing on studies published in the past 10 years. Th

Correlation of longitudinal cerebrospinal fluid biomarkers with cognitive decline in healthy older adults.

BACKGROUND: Abnormal cerebrospinal fluid (CSF) biomarker levels predict development of Alzheimer disease with good accuracy and are thought to precede cognitive deterioration. OBJECTIVE: To investigate whether changes in CSF biomarker levels over time in healthy older adults are associated with a concurrent decline in cognitive performance. DESIGN: Retrospective analysis of longitudinal CSF biomar

Lipoproteins and metabolic control in hypertensive type II diabetics treated with clonidine

Twenty patients with type II diabetes mellitus and hypertension (WHO stages I and II) participated in a 3-month double-blind cross-over study to evaluate the effects of clonidine (75-300 micrograms daily) on blood pressure, glycemic control and plasma lipoproteins. Already after 1 month's treatment with clonidine the systolic and diastolic blood pressures had decreased, from 168/103 to 161/98 mmHg

Early surgical results after pneumonectomy for non-small cell lung cancer are not affected by preoperative radiotherapy and chemotherapy.

BACKGROUND: Higher operative risks after pneumonectomy for non-small cell lung cancer (NSCLC) have been reported after neoadjuvant chemotherapy or radiotherapy, or both. Patients who underwent pneumonectomy for NSCLC were evaluated for effect of neoadjuvant treatment on mortality and morbidity, especially bronchopleural fistula. METHODS: Between 1996 and 2003, 130 consecutive patients underwent pn

Haemodynamic effetcts of prenaterol and cardiac glycosides in patients with recent myocardial infarctions

Prenalterol was given to twenty five patients with acute myocardial infarction. Thirteen patients (group B) had signs of cardiac decompensation while twelve (group A) had not. Ejection fraction was determined with 99mTc-labelled red blood cells before and after prenalterol (50 μg kg-1 body weight), intravenously. In group B this procedure was repeated after digitalization 2 days later. The ejectio
