Age-related changes in the composition, the molecular stoichiometry and the stability of proteoglycan aggregates extracted from human articular cartilage
The heterogeneity of the components of proteoglycan aggregates, their stoichiometry within the aggregate and the aggregates' stability was investigated in normal human articular cartilage specimens (age-range newborn to 63 years). Proteoglycans were extracted from tissue by sequentially extracting them with PBS alone, PBS containing oligosaccharides of hyaluronan, and PBS containing solutions of i

Coevolution of RANTES sensitivity and mode of CCR5 receptor use by human immunodeficiency virus type 1 of the R5 phenotype.
The evolution of human immunodeficiency virus type 1 (HIV-1) coreceptor use has been described as the acquisition of CXCR4 use linked to accelerated disease progression. However, CXCR4-using virus can be isolated only from approximately one-half of individuals with progressive HIV-1 disease. The other half continue to yield only CCR5-using viruses (R5 phenotype) throughout the course of disease. I
How important is the crustacean plankton for the maintenance of water clarity in shallow lakes with abundant submerged vegetation?
1. We measured the abundance and biomass of filter-feeding microcrustacean zooplankton and calculated their grazing impact on phytoplankton biomass during summer in five shallow, mesotrophic to eutrophic lakes. For three of the lakes data exist both from years with dense submerged vegetation and low turbidity (the clearwater state), as well as from years characterised by sparse vegetation and high
Recombinant factor VIIa: its background, development and clinical use.
Purpose of review To examine the development of recombinant FVIIa (rFVIIa); a new concept of inducing hemostasis. It was developed for use in hemophilia patients with inhibitors against FVIII or FIX with the vision to provide these patients with a therapeutical option to be used instead of FVIII or FIX. For the first time it was shown that pharmacological doses of FVIIa induced hemostasis. Recent

Effects on intercombination transition rates and branching ratios - the UV0.01 (3s(2)3p(2) P-3(1,2)-3s3p(3 5)S(2)) multiplet in SiI-like ions revisited
We report on large-scale ab initio calculations for intercombination lines in Si I-like ions. Two measurable quantities, the lifetime of the 3s3p(3 5)S(2) level and the branching ratio of the two lines are discussed, to infer the importance of different features of our calculations. The effects of core polarization, two-body spin-dependent operators and Dirac contra Breit-Pauli approaches are disc
Home Mechanical Ventilation in Sweden. Demography, Indications, Clinical Effects and Survival.
Popular Abstract in Swedish Respiratorbehandling i hemmet till patienter med kronisk underventilering (som kan bero på flera olika grundsjukdomar) har blivit allmänt accepterad, eftersom behandlingen kan ge symptomlindring och förbättrad överlevnad. Syfte: Att undersöka vilka behandlingsmotiv som föranleder start av respiratorbehandling i hemmet och att kvantifiera effekterna av behandlingen på pHome mechanical ventilation in patients with chronic respiratory failure secondary to several different diseases has become widely acceptable as the provision of ventilatory support can provide symptomatic relief and increase life expectancy. Aims: To study the selection criteria underlying the initiation of home mechanical ventilation and to quantify the effects of in relation to blood gases and

Identification and characterization of CMP-NeuAc:GalNAc-IgA1 alpha2,6-sialyltransferase in IgA1-producing cells
Glycosylation defects occur in several human diseases. In IgA nephropathy, IgA1 contains O-glycans that are galactose-deficient and consist mostly of core 1 alpha2,6 sialylated N-acetylgalactosamine, a configuration suspected to prevent beta1,3 galactosylation. We confirmed the same aberrancy in IgA1 secreted by the human DAKIKI B cell line. Biochemical assays indicated CMP-NeuAc:GalNAc-IgA1 alpha
Semi-automatic quantification of myocardial infarction from delayed contrast enhanced magnetic resonance imaging.
Objective. Accurate and reproducible assessment of myocardial infarction is important for treatment planning in patients with ischemic heart disease. This study describes a novel method to quantify myocardial infarction by semi-automatic delineation of hyperenhanced myocardium in delayed contrast enhanced (DE) magnetic resonance (MR) images. Design. The proposed method automatically detects the hy
Provitamins and vitamins D2 and D3 in Cladina spp. over a latitudinal gradient: possible correlation with UV levels
Provitamin D2, vitamin D2 and vitamin D3 were identified in the thallus of a lichen species, Cladina arbuscula (Wallr.) Hale and W.L. Culb. The identification of vitamin D3 was supported by: (1) co-chromatography in both reverse and straight phase HPLC (high performance liquid chromatography), (2) ultraviolet absorption spectrum, and (3) molecular ion peaks demonstrated by ESI (electrospray ionisa
Constitutive and vitamin C-induced, NO-catalyzed release of heparan sulfate from recycling glypican-1 in late endosomes.
The recycling heparan sulfate (HS)-containing proteoglycan glypican-1 (Gpc-1) is processed by nitric oxide (NO)-catalyzed deaminative cleavage of its HS chains at N-unsubstituted glucosamines. This generates anhydromannose (anMan)-containing HS degradation products that can be detected by a specific antibody. Here we have attempted to identify the intracellular compartments where these products ar

Transformations for nonideal uniform circular arrays operating in correlated signal environments
The Davies transformation is a method to transform the steering vector of a uniform circular array (UCA) to one with Vandermonde form. As such, it allows techniques such as spatial smoothing for direction-of-arrival (DOA) estimation in a correlated signal environment, developed originally for uniform linear arrays, to be applied to UCAs. However, the Davies transformation can be highly sensitive t
The uridine diphosphate glucuronosyltransferase 2B15 (DY)-Y-85 and 2B17 deletion Polymorphisms predict the glucuronidation pattern of androgens and fat mass in men
Context: Previous in vitro studies have demonstrated that the UDP glucuronosyltransferase (UGT) 2B15 and UGT2B17 glucuronidate androgens and their metabolites. Objective: Our objective was to determine in vivo whether the UGT2B15 (DY)-Y-85 and the UGT2B17 deletion polymorphisms predict androgen glucuronidation and body composition. Participants: Two population-based cohorts including young adult (
The Nucleus 59Cu - Complex Structure, Shape Evolution, Exotic Decay Modes
High-spin states in the mass A~60 region were populated using the state-of-art gamma-ray spectrometers Gammasphere, Euroball, and GASP in conjunction with dedicated ancillary detectors. In particular, the 59Cu nucleus was studied in several experiments, and a very extensive level scheme was determined. It comprises more than 320 transitions connecting about 150 excited states. Relative to mass, it
