To evaluate the large pore radius of the glomerular capillary filter, plasma-to-urine fractional clearances of a number of endogenous proteins were assessed in normal and in nephrotic Wistar rats in which proximal tubular reabsorption had been inhibited using lysine. The proteins studied varied in radius from 16.2 A (Beta 2-microglobulin) to 90 A (alpha 2-macroglobulin). The nephrotic syndrome was

Spectroscopic radial velocities for several nearby open clusters suggestthat spectra of (especially earlier-type) rapidly rotating stars aresystematically blueshifted by 3 km s-1 or more, relative tothe spectra of slowly rotating ones. Comparisons with astrometricallydetermined radial motions in the Hyades suggests this to be an absoluteblueshift, relative to wavelengths naively expected from stel

BACKGROUND: Cancer prevalence-the proportion of people in a population with a diagnosis of cancer-includes groups with widely differing cancer care needs. We estimated the proportions of the prevalent colon cancer cases requiring initial care, terminal care and follow-up. PATIENTS AND METHODS: Prevalence by year since diagnosis was estimated from incidence and vital status data on 243,471 colon ca

Changes in physical activity with the aim of increasing energy expenditure are usually an important component of childhood obesity treatment. Physical activity also has several other aspects that are positive for the obese child's health, such as improving the metabolic profile and psychological well being. The aim of this paper is to give a short review of what we know about physical activity in

We report on the final electroweak measurements performed with data taken at the Z resonance by the experiments operating at the electron-positron colliders SLC and LEP. The data consist of 17 million Z decays accumulated by the ALEPH, DELPHI, L3 and OPAL experiments at LEP, and 600 thousand Z decays by the SLID experiment using a polarised beam at SLC. The measurements include cross-sections, for

We are reporting about a scintillating fibre tracking detector which is proposed for the precise determination of the absolute luminosity of the CERN LHC at interaction point 1 where the ATLAS experiment is located. The detector needs to track protons elastically scattered under mu rad angles in direct vicinity to the LHC beam. It is based on square shaped scintillating plastic fibres read out by

Gamma-ray lines from Sn-103 have been identified for the first time using EUROBALL and ancillary detectors. The level scheme of Sn-103 has been established by means of particle-gated gamma gamma coincidences. The energy spacing between the g(7/2) and d(5/2) neutron single-particle orbitals is determined from the excited states in Sn-103.

Objectives: To present an analysis of futility that is useful in the clinical setting. Design: Literature review. Material and methods: According to Medline more than 750 articles have been published about medical futility. Three criteria (language, time period, and the authors expressed their own opinions) singled out 43 of them. The authors opinions about futility were analysed using the scheme:

Large eddy simulations of thermal plume in two different scenarios have been carried out using a self-developed parallel computational fluid dynamics (CFD) code, SMAFS (Smoke Movement And Flame Spread), with subgrid-scale turbulence modeled using the Smagorinsky model. Two different initial conditions were used in the simulations, and the results were compared to show that the initial condition ha

The transition rates of the intercombination lines 2s2p(3 5)S(2)(0)-->2s(2)2p(2 3)P(1,2) are computed using a systematic configuration interaction method (SCIV3). The calculated lifetime of the upper S-5(2)o, level is in excellent agreement with a recent experiment. The branching ratio of the two lines is very different from earlier, less accurate theoretical values.

An hepatitis A epidemic among 36 persons, mainly drug addicts, occurring over an 18-week period, is described. There were indications that smuggling and transportation of narcotic drugs in the rectum started the outbreak, either through direct contamination of the drug or manipulation of the drug resulting in contaminated fingers.

The kinetics of dipolar nonradiative energy transfer (DET) between dyes confined to the core−corona interface region of poly(isoprene-b-methyl methacrylate) block copolymers (PI−PMMA) in acetonitrile was analyzed using a new distribution model for energy transfer in spherical micelles. The distribution of block junction points was described by the model of Helfand and Tagami (HT) for the strong se

The focus of this article is on the legal profession's visual self-image of legal authority. It takes a departure from the themes of visual legal communication and discusses the relationship between text and pictures in the legal domain. The discussion concludes with a reflection on the consequences of the modern pictorial evolution. Bearing this discussion in mind, will the development of the ICT

We investigate spin-dependent interband magnetotunneling processes in strained broken-gap resonant tunneling structures made from InAs, AlSb, and GaSb, which are promising materials for quantum devices. InAs/AlSb/GaSb/InAs/AlSb/GaSb double-barrier structures grown on both InAs and GaSb are considered. Transmission coefficients for interband tunneling processes from individual eigenstates in the In

Incorporating bowel into the urinary tract sets the stage for a potentially dangerous situation for the upper part of this tract. Obstruction, reflux and chronic bacteriuria may develop, all of which can all be detrimental. Most reports on renal function have used IVP and serum creatinine only, methods which are inadequate for proper assessment. Long-term follow-up of patients with ileal conduit d

Försäkringskassans handläggare ska avgöra om en individ kan utföra sina arbetsuppgifter eller är i behov av stödåtgärder för att klara sitt arbete. Handläggarna behöver information om i vilken grad sjukdomen eller skadan påverkar funktionsförmågan och möjligheten till arbetsåtergång. De upplever dock ofta att det medicinska underlaget de har tillgång till i form av läkarintyg är ofullständigt. När
