Enzyme replacement therapy in heterozygous females with Fabry disease: results of a phase IIIB study.

2003

Summary: Fabry disease is an X-linked glycosphingolipid storage disorder caused by a deficiency of α-galactosidase A. Affected patients experience debilitating neuropathic pain and have premature mortality due to renal failure, cardiovascular disease or cerebrovascular complications. The disease may be X-linked dominant, since most females heterozygous for Fabry disease are affected clinically. We evaluated the safety, efficacy and pharmacokinetics of agalsidase alfa (Replagal) administered intravenously to female patients with Fabry disease in an open-label, single-centre study. Fifteen severely affected patients received agalsidase alfa at 0.2 mg/kg every other week for up to 55 weeks. Ag…

Elevated Protein Content and Prolyl 4-Hydroxylase Activity in Severely Degenerated Human Annulus Fibrosus

2000

Alterations involved with the intervertebral disc degeneration are partly well described, however, it is not so well known how collagen network is affected by the disease. We analyzed the rate of collagen biosynthesis (estimated by the enzymic activities of prolyl 4-hydroxylase and galactosylhydroxylysyl glucosyltransferase) and the level of hydroxylysylpyridinoline and lysylpyridinoline crosslinks both in normal (n=7) and degenerated (n=7) human annulus fibrosus. The activity of prolyl 4-hydroxylase was significantly increased in degenerated tissue. However, no significant changes in the collagen content or in the amount of hydroxylysylpyridinoline and lysylpyridinoline collagen crosslinks…

A 4-year study of the efficacy and tolerability of enzyme replacement therapy with agalsidase alfa in 36 women with Fabry disease

2009

Although Fabry disease is X linked and considered to affect primarily male hemizygotes, female heterozygotes may experience all the signs and symptoms of this metabolic disorder. This prospective, single-center, open-label, clinical trial was performed to evaluate the long-term response of female patients with Fabry disease to enzyme replacement therapy.Symptomatic women (average age = 47 years) enrolled in this 4-year study were treated with agalsidase alfa (Replagal, Shire HGT, Inc.) at a dose of 0.2 mg/kg, every other week for 4 years (N = 36). Clinical and biochemical assessments were conducted at 12-month intervals.The Mainz Severity Score Index, a measure of total disease burden, was …

Allosteric modulation of nicotinic receptors as a treatment strategy for Alzheimer's disease.

2000

Impairment of the central cholinergic system has a pivotal role in the cognitive decline observed in patients with Alzheimer’s disease (AD). One of the most prominent cholinergic deficits is the reduced number of nicotinic acetylcholine receptors (nAChR) in the brain. Since these receptors are important for memory and learning, enhancing nicotinic neurotransmission is a promising treatment strategy for AD. The two most common approaches to correcting these cholinergic deficits are to increase the synaptic availability of acetylcholine (ACh) by inhibiting acetylcholinesterase (AChE), or to mimic the effects of ACh (nicotinic agonists) by acting directly on nicotinic receptors. Clinical studi…

Galantamine is an allosterically potentiating ligand of neuronal nicotinic but not of muscarinic acetylcholine receptors.

2003

Galantamine (Reminyl), an approved treatment for Alzheimer's disease (AD), is a potent allosteric potentiating ligand (APL) of human alpha 3 beta 4, alpha 4 beta 2, and alpha 6 beta 4 nicotinic receptors (nAChRs), and of the chicken/mouse chimeric alpha 7/5-hydroxytryptamine3 receptor, as was shown by whole-cell patch-clamp studies of human embryonic kidney-293 cells stably expressing a single nAChR subtype. Galantamine potentiates agonist responses of the four nAChR subtypes studied in the same window of concentrations (i.e., 0.1-1 microM), which correlates with the cerebrospinal fluid concentration of the drug at the recommended daily dosage of 16 to 24 mg. At concentrations10 microM, gal…

Flow cytometric analysis of concanavalin A binding to isolated Golgi fractions from rat liver.

1993

Flow cytometry (FCM) has been used repeatedly to study lectin binding to whole cells. However, there are very few attempts to analyze glycoconjugates in isolated subcellular organelles. We have applied FCM to quantitate the specific binding of fluorescein-conjugated concanavalin A (FITC-Con A) to isolated cis and trans fractions of rat liver Golgi complex, the cell compartment involved in glycoprotein maturation and sorting. Our results show similar intensities of Con A-specific binding in the two fractions. Using this method we show a decreased FITC-Con A binding to both Golgi fractions in ethanol-treated rats, which is consistent to previous work on alcoholic effects on galactosyltransfer…

A study of the effect of molecular and aerosol conditions in the atmosphere on air fluorescence measurements at the Pierre Auger Observatory

2010

The air fluorescence detector of the Pierre Auger Observatory is designed to perforin calorimetric measurements of extensive air showers created by Cosmic rays of above 10(18) eV. To correct these measurements for the effects introduced by atmospheric fluctuations, the Observatory contains a group Of monitoring instruments to record atmospheric conditions across the detector site, ail area exceeding 3000 km(2). The atmospheric data are used extensively in the reconstruction of air showers, and are particularly important for the correct determination of shower energies and the depths of shower maxima. This paper contains a summary of the molecular and aerosol conditions measured at the Pierr…
