The matter of this work was to evaluate possibilities of biospecific immobilization of synthetic mannan-penicillin G acylase neoglycoconjugate on Concanavalin A support. The conjugate containing 37% (w/w) of yeast mannan was prepared. Significant biospecific interaction of this neoglycoenzyme with Con A was confirmed by precipitation method. The biospecific sorption of conjugate was investigated u
Many lines of evidence implicate mitochondria in phenotypic variation: ( a) rare mutations in mitochondrial proteins cause metabolic, neurological, and muscular disorders; ( b) alterations in oxidative phosphorylation are characteristic of type 2 diabetes, Parkinson disease, Huntington disease, and other diseases; and ( c) common missense variants in the mitochondrial genome ( mtDNA) have been imp
Goodpasture disease is a prototype autoimmune disease characterized by the formation of autoantibodies against the heterotrimeric basement membrane collagen type IV, which causes a rapidly progressive glomerulonephritis. The pathogenic antibody response is directed to the non-collagenous (NC1) domain of the alpha3 chain of type IV collagen (alpha3(IV)NC1), but not to the homologous region of the a
The phase behavior of lecithin and water mixtures with addition of the hydrocarbon 1,8-cineole (C10H18O) was investigated using light microscopy and H-2 NMR at atmospheric pressure and with a surplus of supercritical carbon dioxide (15 MPa) between 35 and 80degreesC. The lecithin-water (LW) mixtures consisted of 10 and 20wt.% water in lecithin to which 5, 10, and 20wt.% cineole and supercritical c
Aim: To assess the diagnostic concordance of SCID-II and clinicians' estimation of DSM-III-R personality disorders of substance abusers. Method: Clinical diagnoses of substance abusers in inpatient treatment were compared with SCID-II diagnoses (N = 138). Findings: The overall prevalence of personality disorder was 79% for clinical diagnosis and 80% for SCID-H diagnosis. Substantial agreement was
In adult mice, the VpreB genes are expressed in bone marrow progenitor (pro-) and precursor (pre-) B cells. As part of the pre-B cell receptor, the proteins are crucial for the proliferation of these cells and consequently normal B lymphocyte development. Using cell lines, we identified a lineage- and developmental-stage-specific VpreB1 enhancer. Here, we analyze its specificity in vivo by generat
Cytidine deaminase (CD) is a cytoplasmatic enzyme present predominantly in polymorphonuclear cells (PMNC) in inflamed joints. Lactoferrin is situated in the secondary granules of PMNC and is released by secretory/phagocytic stimuli, whereas CD is released mainly upon cell lysis. To study the release of these molecules in arthritic conditions we measured CD and lactoferrin levels in synovial fluid
A total of 10-40% of patients with Hodgkin's disease relapse following initial curative therapy. Intensive follow-up is resource intensive and may identify false relapses. We performed a retrospective review of all patients with Hodgkin's disease treated at our centre between 1990 and 1999 to evaluate the utility of the components of follow-up. A total of 107 patients met the inclusion and exclusi
Background: The first tissues to be deprived of perfusion and oxygenation in a hypovolemic situation and the last ones to be reperfused are the subcutaneous tissue and the gastrointestinal mucosa. We hypothesized that measurements of subcutaneous tissue gases and pH might reflect simultaneous changes in oxygenation of the intestinal mucosa. The aim of this study was to evaluate tissue gases and pH
We investigated the ability of the ichthyotoxic haptophyte Prymnesium parvum to use sewage-originated nutrients applying stable carbon (C) and nitrogen (N) isotope techniques. P. parvum was cultured under N and phosphorus (P) sufficient and deficient conditions in either sewage effluent-based medium or in a nitrate- and phosphate-based control. Cell densities and toxicities were monitored and stab
Adenoviral vector mediated gene delivery has been applied in clinical trials and mechanistic studies to explore new treatment approaches for lung cancers. The expression of coxsackievirus adenovirus receptor (CAR), the primary receptor for the most commonly used adenovirus serotype 5 (Ad5)-based vectors, predominantly determines the permissiveness of lung cancer cells. CAR expression is also sugge
Background: The standard 12-lead ECG remains one of the basic investigations for the early detection and assessment of acute coronary syndromes. It is easy to perform, anywhere and anytime, and can be digitally transmitted within minutes to an emergency medical service for remote advice and triage. But the conventional ST-segment deviation criteria are of limited diagnostic accuracy. The purpose o
In this study, we developed a microdispenser technique in order to create protein patterns for guidance of neurites from cultured adult mouse dorsal root ganglia (DRG). The microdispenser is a micromachined silicon device that ejects 100 picolitre droplets and has the ability to position the droplets with a precision of 6-8 mu m. Laminin and bovine serum albumin (BSA) was used to create adhesive a
The plasma membrane H+-ATPase is activated by binding of 14-3-3 protein to the phosphorylated C terminus. Considering the large number of 14-3-3 and H+-ATPase isoforms in Arabidopsis (13 and 11 expressed genes, respectively), specificity in binding may exist between 14-3-3 and H+-ATPase isoforms. We now show that the H'-ATPase is the main target for 14-3-3 binding at the plasma membrane, and that
The hydrochloride salts of 5-aminolevulinic acid (ALA) and its methyl ester (m-ALA), respectively, were dissolved in a lipid sponge phase comprising monoolein, propylene glycol and aqueous buffer at concentrations of approximately 0.25% and 16% w/w m-ALA. The iontophoretic and passive delivery of ALA and m-ALA from this formulation through porcine skin in vitro were measured and compared to formul
The identification of the BTK(Bruton's tyrosine kinase) gene defective in human immunoglobulin deficiency X-Iinked agammaglobulinaemia (XLA) and characterisation of BTK exon-intron boundaries has now allowed the analysis of mutations and polymorphisms at the level of genomic DNA, Using Southern blot analysis and the polymerase chain reaction single strand conformation polymorphism (PCR-SSCP) assay
Background: Craniopharyngioma is a parasellar tumour that, although benign, tends to behave aggressively. It can occur at any age but most commonly presents in childhood or adolescence. Objectives: to investigate the frequency and severity of problems associated with craniopharyngioma, using the large international database (KIMS) for adult patients with GH deficiency (GHD), and to assess the diff
