The efficacy of pegylated interferon alfa-2b alone or in combination with lamivudine for the treatment of patients with hepatitis B e antigen (HBeAg) negative (-) chronic hepatitis B (CHB) is understudied.One hundred twenty-six patients with HBeAg(-)chronic hepatitis B received pegylated interferon alfa-2b > or =1.5 micro g/kg/wk for 48 weeks. Ninety of those subjects were randomly selected to receive concomitant treatment with lamivudine 100 mg/d. The coprimary end points were the subjects' virologic (hepatitis ...

Abstract The total polar fraction and individual phenols present in virgin olive oil were tested for their antioxidant effect in refined olive oil. Hydroxytyrosol and caffeic acid showed protection factors greater than BHT. Protocatechuic and syringic acid were also found to have antioxidant activity. Tyrosol, p‐hydroxyphenylacetic acid, o‐coumaric acid, p‐coumaric acid, p‐hydroxybenzoic acid and vanillic acid had very little or no effect, and their contribution to the stability of the oil is negligible.

The stability of 24 samples of Greek virgin olive oil was examined in relation to total polyphenol content, and individual phenols were determined by reversed-phase HPLC. Tyrosol, the major olive-oil phenol, is not correlated with the shelf-life of the oil. Total polyphenol content and hydroxytyrosol-to-tyrosol ratio have a significant linear correlation with the resistance of the oil to autoxidation.

A hybrid intelligent system is presented for the identification of microcalcification clusters in digital mammograms. The proposed method is based on a three-step procedure: (a) preprocessing and segmentation, (b) regions of interest (ROI) specification, and (c) feature extraction and classification. The reduction of false positive cases is performed using an intelligent system containing two sub-systems: a rule-based and a neural network sub-system. In the first step of the classification schema 22 ...

We compute the corrections to heterotic-string backgrounds with (2,0) world-sheet supersymmetry, up to two loops in sigma-model perturbation theory. We investigate the conditions for these backgrounds to preserve spacetime supersymmetry and we find that a sufficient requirement for consistency is the applicability of the ∂-lemma. In particular, we investigate the α' corrections to (2,0) heterotic-string compactifications and we find that the Calabi-Yau geometry of the internal space is deformed to a ...

We show that the holonomy of the supercovariant connection of IIB supergravity is contained in SL(32, ). We also find that the holonomy reduces to a subgroup of SL(32 − N) ⋉ (⊕N 32−N) for IIB supergravity backgrounds with N Killing spinors. We give the necessary and sufficient conditions for a IIB background to admit N Killing spinors. A IIB supersymmetric probe configuration can involve up to 31 linearly independent planar branes and preserves one supersymmetry.

We show that the holonomy of the supercovariant connection for M-theory backgrounds with N Killing spinors reduces to a subgroup of SL(32−N,)⋉(⊕N32−N). We use this to give the necessary and sufficient conditions for a background to admit N Killing spinors. We show that there is no topological obstruction for the existence of up to 22 Killing spinors in eleven-dimensional spacetime. We investigate the symmetry superalgebras of supersymmetric backgrounds and find that their structure constants are ...

Tissue defects in the antihelix and the concha due to oncological resection and trauma can be successfully repaired with a subcutaneously based postauricular island flap. Alternative methods of regional reconstruction usually need two stages or may require grafts in some patients. We present the one‐stage technique, as described by Masson, without grafts, to provide adequate reconstruction and aesthetic restoration of the area, illustrated by 62 patients. In all patients there has been a follow‐ ...

We examined the prognostic value of soluble intercellular adhesion molecule-1 (sICAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) on in-hospital mortality in patients with ischaemic stroke. Methods We recruited 241 consecutive patients ≤65 years of age who were admitted with acute ischaemic stroke. Serum levels of sICAM-1 and sVCAM-1 were ...

To meet this requirement, honeycomb breeding was performed at a low density within two dry bean populations ( Phaseolus vulgaris L.) under typical open‐field conditions and in an adjacent greenhouse. Nineteen progeny lines were formed through selection of nine and ten of the highest‐yielding plants in the greenhouse and the field, respectively. ...

The KRAS oncogene has been extensively studied for more than three decades, however, it is only recently that it attained a central role in the clinical decision-making process for the practicing oncologist. Recently, based on retrospective analyses of large randomized clinical trials, the use of anti-epidermal growth factor (EGFR) monoclonal antibodies, cetuximab and panitumumab, was restricted to patients with metastatic colorectal cancer that carry the "wild-type"KRAS genotype.

Monocyte-chemotactic-protein-1 (MCP-1) plays vital roles in immune response, angiogenesis, and pregnancy outcome. We investigated plasma MCP-1 concentrations in 40 mothers and their 20 intrauterine-growth-restricted (IUGR) and 20 appropriate-for-gestational-age (AGA) fetuses and neonates on postnatal days 1 (N1) and 4 (N4). Maternal and fetal MCP-1 concentrations were decreased (P<001 and P = .018, resp.), whereas N1 MCP-1 concentrations were elevated in IUGR group (P = .012). In both groups, fetal MCP-1 concentrations ...

Multiple endocrine neoplasia type 2A (MEN2A) is a syndrome of familial neoplasias characterized by medullary thyroid carcinoma (MTC), pheochromocytoma and hyperplasia of the parathyroid glands. RET protooncogene mutations are responsible for MEN 2A. Mutations in exons 10 or 11 have been identified in more than 96% of patients with MEN 2A. We herein report for the first time a patient with MEN 2A harboring a mutation (Gly(533)Cys) in exon 8. A 66-year old male patient was referred to our department ...

The field of the potential applications of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors (statins) beyond their unambiguous cardiovascular beneficial effects is steadily increasing. In this regard, statins have also been shown to possess anti-inflammatory, immunomodulatory, antioxidant and growth inhibitory properties. Regarding their role in carcinogenesis, both preclinical and clinical studies report conflicting results. Intriguingly, accumulating evidence suggests that statins ...

The new expressions are implemented for both a single insulated conductor and a typical three-phase single-core cable arrangement ...
