Background: An alternative to standard approaches to uncover biologically meaningful structures in micro array data is to treat the data as a blind source separation ( BSS) problem. BSS attempts to separate a mixture of signals into their different sources and refers to the problem of recovering signals from several observed linear mixtures. In the context of micro array data, "sources" may corres

Studies on patients with long-term diabetes survival without severe complications can give information about protective factors. Therefore, the present study aims to describe the long-term survival of patients with diabetes during successive periods following the introduction of insulin therapy in 1923. After registration in 1973 of the first local diabetic patient in Jonkoping with a fifty-year s

Purpose Description of mucus on the corneal surface and in the precorneal tear film in keratoconjunctivitis sicca (KCS). Methods In all, 24 patients with KCS examined with slit lamp and by non-contact photomicrography. Results Material interpreted as mucus seemed to exist in three varieties: one optically dense, light reflecting, and with definite forms ( fine threads, variously thick and long str

This article shows that language must be conceived of as a natural system that becomes structured through rhythmic driving forces. This gives weight to the hypothesis that rotatio¬nal dynamics is basic to the effects that selective textual movement patterns have on the evolution of texture, i.e. a text surface. The experimental procedure has been focused on the manipulation of text translation, as

The relative deficiency of the official Terminologia Anatomica with regard to the veins of the lower limbs was responsible for a nonuniform anatomic nomenclature in the clinical literature. In 2001, an International Interdisciplinary Committee updated and refined the official Terminologia Anatomica regarding the veins of the lower limbs. Recommendations for terminology were included in an updating

Structural properties of polymer brushes on nanopatterned surfaces in good solvent have been determined by computer simulations. Scaling relations for the brush height and brush width are proposed. The properties of the central part of the patterned brush remain constant as long as the pattern is wider than a few times the brush height. The results agree qualitatively with recent AFM experiments,

Purpose: We tested the biocompatibility of nitinol, a nickel titanium alloy, and stainless steel (SS) as bladder implant materials. Materials and Methods: Rats received a nitinol implant, an SS implant or were sham controls. Two, 3, 6 and 8 weeks following implantation 24-hour voiding behavior studies were per-formed to investigate bladder irritation. All animals were sacrificed 8 weeks after impl

The aim of this study was to examine whether small biopsy specimens are representative of the whole human skeletal muscle or whether the different fibre types are unevenly distributed at different depths of the muscle. Ten micrometre thick cross-sections of whole human tibialis anterior were prepared using LKB PMV Cryo-Microtomes with a stroke length of 160 to 480 mm and the sections were stained

BACKGROUND: Recently, a -168A-->G polymorphism in the MHC class II transactivator gene (MHC2TA) was shown to be associated with increased susceptibility to myocardial infarction (MI). AIM: To confirm the association between the MHC2TA -168A-->G polymorphism and MI and to study its putative role for microalbuminuria, the metabolic syndrome (MetS) and cardiovascular mortality.
