Glycogen synthase kinase 3 beta (GSK-3beta) has a central role in Alzheimer's disease (AD). Selective inhibitors which avoid tau hyperphosphorylation may represent an effective therapeutical approach to the AD pharmacotherapy and other neurodegenerative disorders. Here, we describe the synthesis, biological evaluation, and SAR of the small heterocyclic(More)
OBJECTIVE To investigate the influence of -308 tumour necrosis factor-alpha (TNF-alpha) promoter polymorphism and circulating TNF-alpha levels in the clinical response to the infliximab treatment in patients with rheumatoid arthritis (RA). METHODS One hundred and thirty-two RA patients were genotyped for TNF-alpha promoter by polymerase-chain reaction(More)
Extracellular lipase synthesis by Streptomyces lividans 66 carrying the cloned lipase gene (lipA) from Streptomyces exfoliatus M11 was found to be growth phase dependent, since lipase was secreted into the medium mainly during the stationary phase; S1 nuclease protection experiments revealed abundant lipA transcripts in RNA preparations obtained during the(More)
A white solid compound was isolated from the chloroform extract of the leaves of Senna villosa. The material was identified by (1)H-NMR, (13)C-NMR, IR and EM methods as (8-hydroxymethylen)-trieicosanyl acetate, a new compound with biological activity, which was tested in vitro at concentrations of 1.65, 3.3 and 6.6 microg/ml for inhibition of the growth of(More)
A gene encoding an extracellular lipase from Streptomyces sp. M11 was cloned in the high-copy-number vector pIJ486, using S. lividans 66 as host. A 28-kDa protein was secreted by S. lividans carrying pB13, which harbors a 6-kb insert, and identified as the product of the cloned gene. Comparison of the N-terminal amino acid (aa) sequence of the purified(More)
The purpose of the present work was to produce and characterize poly(lactic acid)-poly(ethylene glycol) (PLA-PEG) nanoparticles (size lower than 300 nm) containing a high loading of plasmid DNA in a free form or co-encapsulated with either poly(vinyl alcohol) (PVA) or poly(vinylpyrrolidone) (PVP). The plasmid alone or with PVA or PVP was encapsulated by two(More)
BACKGROUND Human enteroviruses (HEV) are the commonest cause of viral meningitis as well as other pathologies, therefore HEV characterization is important both in patient management and epidemiological investigation. OBJECTIVES A 10-year study of patients with enteroviral infection was carried out in Spain to determine the underlying etiology. STUDY(More)
This study represents a complete comparative analysis of the most widely used African swine fever (ASF) diagnostic techniques in the European Union (EU) using field and experimental samples from animals infected with genotype II ASF virus (ASFV) isolates circulating in Europe. To detect ASFV, three different PCRs were evaluated in parallel using 785 field(More)
Docking functions are believed to be the essential component of docking algorithms. Both physically and statistically based functions have been proposed, but there is no consensus about their relative performances. Here, we propose an evaluation approach based on exhaustive enumeration of all possible docking solutions obtained with a discretized(More)
An extracellular lipase (Lip)-encoding gene from Streptomyces albus G has been cloned and sequenced. It encodes a Lip with 82% sequence identity to another previously cloned Lip from a Streptomyces species not closely related. These two sequences can be aligned with 33% identity to the sequence of Lip1 from the antarctic psychrotroph Moraxella TA144 [G.(More)
