Background: Vitamin A supplementation (VAS) at birth has been associated with decreased mortality in Asia. Bacille Calmette-Guerin (BCG) vaccine is given at birth in tuberculosis-endemic countries. Previous studies suggest that VAS may influence the immune response to vaccines. Objective: Our objective was to examine whether VAS influences the immune response to simultaneously administered BCG vac

Background. It is well known that portacaval shunting ultimately leads to a decrease in liver volume and hepatic function, but the mechanism is uncertain. The aim of the present study was to evaluate the effect of portacaval shunting (PCS) upon the morphological changes that occur in the liver in rats after port caval. anastomosis. Materials and methods. Sixty-six male rats underwent either PCS (n

World-wide, the development of community-based geriatric rehabilitation has received increased attention. In Sweden, national reforms during the 1990s aimed at improved quality of geriatric rehabilitation. This paper focuses clients' perceptions of the rehabilitation process, dependence in activities of daily living (ADL), and subjective well-being in a one-year perspective. A study-specific quest

The beta -decays of the neutron-rich nuclei Be-12 and Ne-29 have been studied. The statistical correlations between the almost identical half-lives of Be-12 and its daughter B-12 are analysed for a large sample of Be-12 decay data. Stringent mutual bounds are obtained on the parameter set, leading to a precise determination of the Be-12 half-life of 21.50 +/- 0.04 ms. From a simultaneous detection

OBJECTIVE: To investigate signs of liver disease, and biochemical and immunological markers in blood donors with isolated GBV-C/HGV viremia. METHODS: Eighteen donors with isolated GBV-C/HGV viremia were followed up 3-5 years after initial identification. Testing for GBV-C/HGV RNA, GBV-C/HGV-E2 antibodies and a range of biochemical and immunological tests was performed. Thirteen donors consented to

The insertion of lithium in anatase TiO2 nanoparticles under ultrahigh vacuum (UHV) conditions is studied using x-ray absorption spectroscopy (XAS) and resonant photoelectron spectroscopy (RPES) at the Ti L-2,L-3 edge. It is demonstrated that XAS can be used to monitor the separation into an anatase phase and a lithium titanate phase of formal stoichiometry Li0.5TiO2. The initial state properties

As a model for redox components on the donor side of photosystem II (PS II) in green plants, a supramolecular complex 4 has been prepared. In this, a ruthenium(II) tris-bipyridyl complex which mimics the function of P680 in PS II, has been covalently linked to a tyrosine unit which bears two hydrogen-bonding substituents, dipicolylamine (dpa) ligands. Our aim is to mimic the interaction between ty

We report the observation of neutrons rf:leased from d(d,n) He-3 fusion reactions in the focus of 200 mJ, 160 fs Ti:sapphire laser pulses on a deuterated polyethylene target. Optimizing the fast electron and ion generation by applying a well-defined prepulse led to an average rate of 140 neutrons per shot. Furthermore, the production of a substantial number of MeV gamma rays could be observed. The

Popular Abstract in Swedish Sammanfattning: För religiösa sikher är Guru Granth Sahib en helig skrift som manifester ontologiskt gudomliga och förkroppsligar de historiska guruernas lära och uppenbarelseerfarenheter. Samtidigt har sikherna tagit uppfattningen om en helig skrift längre än någon annan religiös tradition genom att behandla Guru Granth Sahib som en levande guru med både andlig auktoriSummary: For religious Sikhs, the Guru Granth Sahib is a holy scripture which enshrines ontologically divine words and the teaching and revelatory experiences of historical human Gurus. Simultaneously the Sikhs have taken the concept of a sacred scripture much further than any other religious community by treating the Guru Granth Sahib as a living Guru invested with spiritual authority and agency

Hur biomedicinsk forskning populariseras för att anpassa till en bredare allmänhet. Det handlar om att skapa en positiv upplevelse och få allmänhetens gillande för en kontroversiell medicinsk teknik.

The time-dependent orienteering problem is dual to the time-dependent traveling salesman problem. It consists of visiting a maximum number of sites within a given deadline. The traveling time between two sites is in general dependent on the starting time. For ε greater than or equal 0, we provide a (2+ ε)-approximation algorithm for the time-dependent orienteering problem which runs in polynomial

This paper reports a pilot study and three case studies to examine aimed at studying if a quality system, according to the ISO 9000 quality standard, can be visualised, exploring how the visualisation should be designed in order to support continuous improvements and evaluating the design process for development of prototypes. By discussing with the research team, three companies in southern Swede

Objective Skewed gender distribution and falsely assigned gestational age lead to unnecessary or late obstetric intervention in prolonged pregnancy. The aim of this study was to examine the consequences of a fetal gender-dependent systematic 1.5-day dating error at ultrasound fetometry. Material and methods A total of 82484 singleton deliveries greater than or equal to 37 weeks at 11 hospitals in

The rimming flow of condensate in horizontal rotating dryer cylinders has been studied computationally by solving the full Navier-Stokes equations coupled with a volume of fluid method for tracking the free surface. It was shown that significant variations in both condensate velocity and thickness exist at moderate dryer speeds, whereas at higher speeds the variations are of less significance. Reg
