Human skin fibroblasts in different growth states were incubated with [3H]glucosamine and/or Na(2)35SO4 and extracted with Triton X-100 for various periods of time. Free heparan-sulphate oligosaccharides and protein-bound heparan-sulphate chains were separated by chromatography on octyl-Sepharose and analyzed. A pool of endogenously produced oligosaccharides, present in the cultured cells and isol

Målet med arbetet som presenteras i denna licentiatuppsats är att genomföra en analys av problemkomplexet inomhusluft och att med ledning av denna analys anvisa vägar att minska inneluftproblem i framtida byggande. Utifrån detta har tre delsyften formulerats: (1) Analysera existerande inneluftproblem och i samband därmed beskriva vilka faktorer i inomhusluften som medför problem, vilka faktorer so

Background. The incidence of non-Hodgkin lymphoma and prevalence of obesity are increasing globally. A suggested positive association between obesity and risk of non-Hodgkin lymphoma has prompted us to investigate the relationship between body mass index (BMI) and risk of malignant lymphoma subtypes in a population-based case-control study. Methods: Telephone interviews were conducted with 3055 ca

Direct gene transfer to the adult brain is dependent on vectors that transduce non-dividing cells, such as lentiviral vectors. Another aspect of the development of gene therapy to the brain is the need for cell-specific transgene expression. Expression from vesicular stomatitis virus G-protein (VSV-G) pseudotyped lentiviral vectors has been reported to be mainly neuron specific in the brain. We co

Multiple sequence alignment (MSA) is an essential prerequisite for many sequence analysis methods and valuable tool itself for describing relationships between protein sequences. Since the success of the sequence analysis is highly dependent on the reliability of alignments, measures for assessing the quality of alignments are highly requisite.

Orthostatic hypotension (OH) increases the risk of incident cardiovascular disease (CVD) and all-cause mortality in population-based cohort studies. Whether OH is associated with development of cardiac anomalies has not been sufficiently explored.

Abstract. Purpose: This study aimed to evaluate local response on multifocal electroretinography (mfERG) and to assess retinal thickness with optical coherence tomography (OCT) after focal laser treatment in areas with retinal oedema and exudates in patients with diabetic retinopathy. Methods: Twelve diabetes patients (aged 60 +/- 14 years, diabetes duration 16 +/- 8 years) treated with focal or g

Using simple sequence-based potentials, the folding properties of a designed three-helix-bundle protein, an alpha-helix and a beta-hairpin are studied. The three-helix-bundle protein is modelled using 5-6 atoms per amino acid and is found to undergo a first-order-like folding transition in which chain collapse and helix formation cannot be separated, which is in-accord with experimental data. The

Abstract While outcome studies in pediatric obesity have received considerable attention, research on different components of effective interventions remains limited. Little is known which psychological method (i.e., behavior modification, cognitive behavior therapy and family therapy) is most useful or how the choice of program delivery (group/individual) influences the intervention outcomes. Gro

The efficacy and safety of olaparib, an oral poly(ADP-ribose) polymerase (PARP) inhibitor, was investigated in a subgroup of patients with germline BRCA1/2 mutated (gBRCA1/2m) advanced ovarian cancer who had received ≥3 prior lines of chemotherapy. Primary data from this Phase II study (Study 42, ClinicalTrials.govNCT01078662) have been reported previously.

OBJECTIVE: To determine whether perturbations of insulin-like growth factor-1 (IGF-1) and IGF binding protein-3 (IGFBP-3) were associated with the presence of chronic widespread pain (CWP) in men. METHODS: The European Male Ageing Study (EMAS) is an 8-center population-based study of men aged 40-79 years recruited from population registers. A questionnaire asked about the presence and duration of

BACKGROUND: Proghrelin, produced by the ghrelin (A-like) cells of the gastric mucosa, gives rise to cleavage products, including desacyl ghrelin, acyl ghrelin and obestatin. The products are thought to be secreted concomitantly. In an earlier study we found acyl ghrelin and obestatin, but not desacyl ghrelin, to suppress the release of hormones from isolated islets of mouse and rat pancreas. RESUL

AMP-activated protein kinase (AMPK) is an important regulator of cellular energy status. In adipocytes, stimuli that increase intracellular cyclic AMP (cAMP) have also been shown to increase the activity of AMPK. The precise molecular mechanisms responsible for cAMP-induced AMPK activation are not clear. Phosphodiesterase 3B (PDE3B) is a critical regulator of cAMP signaling in adipocytes. Here we

Nicaragua and Costa Rica have twice turned to the International Court of Justice (ICJ) to resolve disputes related to environmental damage occurring in a transboundary context. In these two cases the Court has to consider at least two issues. The first issue concerns the territorial status of a disputed border area. The disagreement is triggered by natural variations of the San Juan River at the b
