BACKGROUND: Vascular rings are a classical cause of tracheal and esophagus compression. We report the case of such an abnormality in an infant with neurofibromatosis. CASE REPORT: A 1 week-old male infant with a familial neurofibromatosis presented a stridor with severe respiratory distress. A vascular ring was demonstrated and operated on. The stridor persisted after surgery. A postoperative oeso

The interaction of ink and newspaper has been investigated and the specific question of penetration of ink into the paper has been addressed with a nuclear microprobe using particle induced X-ray emission, The penetration depth of the newsprint is a critical factor in terms of increasing the quality of newsprint and minimising the amount of ink used. The objective of the experiment was to relate t

In this study a method for the analysis of simultaneous multiple measurements of kinematics and stabilizing forces related to human postural dynamics is proposed. Each subject in a group of normal subjects (n=10) was tested with eyes-open and eyes-closed with simultaneous but uncorrelated vestibular and proprioceptive stimuli in order to investigate the contributions of individual sensory feedback

Objective: Cryptorchidism is a common congenital genito-urological anomali in males with increased risk of infertility and testicular cancer. In this retrospective study the results of operations for undescended testis at Landspitalinn University Hospital were reviewed with special emphasis on patients diagnosed with testicular cancer later in life. Material and methods: The study includes 593 mal

About one-third of all women treated for breast cancer develop arm lymphedema. In addition to the worry of the cancer itself, the swollen and heavy arm is both a physical and a psychosocial handicap for the patients. Previous surgical and conservative treatments have not always given satisfactory and permanent results, conceivably because lymphedema causes hypertrophy of the subcutaneous adipose t

A central problem in computer vision is to reconstruct the three-dimensional structure of a scene from a set of two-dimensional images. Traditionally this is done by extracting a set of characteristic points in the scene and to compute a reconstruction of these points. In this thesis we propose a novel method that allows reconstruction of a wider class of objects, including curves and surfaces. As

This article is advancing the bio-kinematic and demonstrates that the discovered mechanism can capture emergent "AaO" units and track their growth in complexity. It is demonstrated that the textual morphogenesis is generating corresponding informational invariants. On the basis of the translation function, it is made evident that the sequential textual translation of English to Swedish and Swedish

BACKGROUND: Angiotensin II (Ang II) has been implicated in the development of cardiac fibrosis. The aims of the present study were to examine expression and activity of ACE and of angiotensin receptors in human cardiac fibroblasts cultured from dilated cardiomyopathic and ischemic hearts. The effects of Ang II on fibroblasts were also investigated. METHODS AND RESULTS: Human cardiac fibroblasts we

Knowledge of how the content of low molecular weight carbohydrates (LMWC), including the raffinose family oligosaccharides (RFO; raffinose, stachyose and verbascose), changes in unripe peas (Pisum sativum) around harvest time, is today limited. An early and a late maturing cultivar of peas were harvested with 24 h of each other on seven different occasions, of which three were chosen for this stud

This thesis consists of five papers (Paper A-E) on statistical modeling of diffusion processes. Two papers (Paper A & D) consider Maximum Likelihood estimators for non-linear diffusion processes. An offline Maximum Likelihood estimator is derived in Paper A, and it is shown that this estimator is computationally more efficient than other Maximum Likelihood estimators. The offline algorithm is

The azimuthal distributions of photons and charged particles with respect to the event plane are investigated as a function of centrality in Pb-208 + Pb-208 collisions at 158 (.) A GeV/c in the WA98 experiment at the CERN SPS. The anisotropy of the azimuthal distributions is characterized using a Fourier analysis. For both the photon and charged particle distributions the first two Fourier coeffic

Popular Abstract in Swedish Våra vita blodceller bildas i benmärgen och när de mognat färdigt hamnar de i blodcirkulationen. Det finns olika typer av vita blodceller och varje typ har sin egen funktion. En speciell typ av vit blodcell, nämligen den myeloida vita blodcellen (neutrofilen), spelar en mycket viktig roll i kroppens första försvar mot invaderande bakterier. När bakterier kommer in i kroIn myelopoiesis, neutrophils and monocytes/macrophages are formed from a common myeloid precursor cell in the bone marow. During maturation of neutrophils, cytoplasmic granules are formed in the cells and the content of these granules is critical for the function of neutrophils in the first line of defense against invading microorganisms. The Bactericidal/Permeability-Increasing protein (BPI) is s

Three-dimensional imaging of fuel tracer planar laser-induced fluorescence in a homogeneous charge compression ignition (HCCI) engine is presented. A high-speed multiple Nd:YAG laser and detection system, in combination, with a scanning mirror, are used to collect eight images, with an equidistant separation of 0.5 mm. Three-dimensional isoconcentration surfaces calculated from the data are visual

Clinical research, when children involved, may cause difficult ethical problems for both caregivers and parents. Informed consent has to be obtained from the parents and from the child depending on age and maturity. The concept of informed consent is complicated and depending on the ability of communication between the professionals and the parents. The aim of the study was to illuminate parents l
