Nucleoside diphosphate kinase (NDPK) was purified from Drosophila melanogaster by a combination of anion-exchange, hydroxyapatite, and reversed-phase chromatography. The identity of the purified enzyme was confirmed by sequencing internal peptides (the N-terminus appeared to be blocked). Post-translational modifications were investigated by using protein chemical and mass spectrometric methods. An
The present paper describes the synthesis and use of the hydrophobic squaric decyl ester glycosides in neoglycoconjugate chemistry. The 2-aminoethyl glycosides of agr-D-mannopyranose, lactose, globotriose, globotetraose, GM3, and sialyl Lewisx, as well as the 2-(2-aminoethylthio)ethyl glycoside of agr-D-mannopyranose, beta-D-glucopyranose, and galabiose were reacted with squaric acid didecyl ester
We developed a new algorithm that fits optical coherence tomography (OCT) signals as a function of depth to a general theoretical OCT model which takes into account multiple scattering effects. With use of this algorithm, it was possible to extract both the scattering coefficient and anisotropy factor from a particular region of interest in an OCT image. The extraction algorithm was evaluated agai
Genes for two structurally and functionally different dihydroorotate dehydrogenases (DHODHs, EC 1.3.99.11), catalyzing the fourth step of pyrimidine biosynthesis, have been previously found in yeast Saccharomyces kluyveri. One is closely related to the Schizosaccharomyces pombe mitochondrial family 2 enzymes, which use quinones as direct and oxygen as the final electron acceptor. The other one res
Intestinal spirochetes (Brachyspira spp.) are causative agents of intestinal disorders in animals and humans. Phylogenetic analysis of cloned 16S rRNA genes from biopsies of the intestinal mucosa of the colon from two Swedish 60-years old adults without clinical symptoms revealed the presence of intestinal spirochetes. Seventeen clones from two individuals and 11 reference strains were analyzed an
High-resolution electron spectroscopy applied under resonant Auger-Raman conditions is shown to be a powerful tool for characterizing complex potential energy surfaces of core-excited states in polyatomic systems. BF3 is used as a prototype molecule: excitation of the Bls --> 2a(2)(") transition leads to an exceptional out-of-plane vibrational excitation resolved over a wide energy range (3.6 eV).
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
