A series of nine casbane diterpenes, compounds 5-13, exhibiting either cis or trans ring junctions were isolated from the Hainan soft coral Sinularia depressa. The structures of this group of compounds, the basic member of which was named depressin (5), were established by detailed spectroscopic analysis. In addition, the absolute configuration of the main(More)
Luteinizing Hormone Releasing Hormone analogues (LHRHa) are considered the treatment of choice in central precocious puberty (CPP). Final height after therapy is usually higher than the predicted one before treatment, but about 60% of patients do not reach their genetic target. The association of Growth Hormone (GH) with LHRHa could be useful in a subgroup(More)
The gold standard procedure for the evaluation of vesicoureteral reflux (VUR) is the radiographic voiding cystourethrography (VCUG); direct radionuclide voiding cystography (DRVC) is an alternative method for detecting VUR. A new imaging procedure, voiding urosonography (VUS) with contrast medium, has recently been introduced. We have carried out a(More)
Regular physical activity plays a key role in the management of children and adolescents with Type 1 diabetes mellitus but it is not considered as a treatment for diabetes. Aim of this study was to investigate time spent exercising, adherence to the programme for a safe exercise and ability of young people with diabetes to take appropriate measures to(More)
The X-ray crystal structure of the fluorescent antitumor sulfonamide carbonic anhydrase (CA, EC, 4.2.1.1) inhibitor (4-sulfamoylphenylethyl)thioureido fluorescein (1) in complex with the cytosolic isoform hCA II is reported, together with a modeling study of the adduct of 1 with the tumor-associated isoform hCA IX. Its binding to hCA II is similar to that(More)
Aminoacylase 1 is a zinc-binding metalloprotease catalyzing the hydrolysis of N(alpha)-acylated l-amino acids; it presents altered expression levels in different renal and small cell lung carcinomas. A description of its redox and oligomerization state was achieved by combined biochemical and mass spectrometric procedures. A topological analysis of the(More)
A tri-functional monomeric primase-polymerase domain encoded by the plasmid pIT3 from Sulfolobus solfataricus strain IT3 was identified using a structural-functional approach. The N-terminal domain of the pIT3 replication protein encompassing residues 31-245 (i.e. Rep245) was modeled onto the crystallographic structure of the bifunctional primase-polymerase(More)
NF-kappaB/Rel factors control programmed cell death (PCD), and this control is crucial to oncogenesis, cancer chemoresistance, and antagonism of tumor necrosis factor (TNF) alpha-induced killing. With TNFalpha, NF-kappaB-mediated protection involves suppression of the c-Jun-N-terminal kinase (JNK) cascade, and we have identified Gadd45beta, a member of the(More)
0022-2836/$ see front matter © 2008 E Gadd45α, β, and γ proteins, also known as growth arrest and DNA damage-inducible factors, have a number of cellular functions, including cell-cycle regulation and propagation of signals produced by a variety of cellular stimuli, maintaining genomic stability and apoptosis. Furthermore, Gadd45β has been indicated as a(More)
Cationic lipodepsipeptides from Pseudomonas spp. have been characterized for their structural and antimicrobial properties. In the present study, the structure of a novel lipodepsipeptide, cormycin A, produced in culture by the tomato pathogen Pseudomonas corrugata was elucidated by combined protein chemistry, mass spectrometry and two-dimensional NMR(More)
