Contribution to the knowledge of the genus Phlebia in Italy
The presence of two corticioid taxa belonging to the genus Phlebia (Basidiomycota), collected from Sicily, Italy is reported. A macro- and micromorphological descriptions of P. acanthocystis and P. nothofagi added of ecological and distributional data are here provided. P. acanthocystis is reported as new for Italy.

Sea urchin neural alpha 2 tubulin gene: isolation and promoter analysis
Expression of Tα2 gene, during sea urchin Paracentrotus lividus development, is spatially and temporally regulated. In order to characterize this gene, we isolated the relevant genomic sequences and scanned the isolated 5′-flanking region in searching for cis-regulatory elements required for proper expression. Gel mobility shift and footprinting assays, as well as reporter gene (CAT and β-gal) expression assays, were used to address cis-regulatory elements involved in regulation. Here we report that an upstream 5′-flanking fragment of PlTα2 gene drives temporal expression of reporter genes congruent with that of endogenous Tα2 gene. The fragment contains cis-elements able to bind nuclear proteins from the gastrula stage (at which the Tα2 gene is expressed) whose sequences could be consistent with the consensus sequences for transcription factors present in data bank

HBV-DNA suppression and disease course in HBV cirrhosis patients on long-term lamivudine therapy
In hepatitis B virus (HBV) cirrhosis patients on long-term lamivudine (LAM), the relationships between HBV suppression, development of viral resistance and disease outcome are unclear. We analysed the dynamic of serum HBV-DNA and its relationship with the clinical course of 59 patients (52 males, mean age 51.4 +/- 8.4 years, 12 HBeAg positive and 47 HBeAg negative, and 57 genotype D and two genotype A) with cirrhosis (45 in Child-Turcotte-Pugh class A) and high levels of serum HBV-DNA (median 14.7 x 10(7) genomes/ml) treated with LAM [median (range): 44 (15-78) months]. A total of 50 patient (84.7%) achieved a virological response (serum HBV-DNA negative by PCR) during the first 6 months of therapy, and nine (13.3%) achieved a reduction in viral load of > 3 log10. Mutations in the YMDD motif of HBV polymerase were documented in 26 patients [median (range) 18: (7-42) months]. At the time of the emergence of mutants, 22 patients had HBV-DNA 10(5) genomes/ml and of ALT values in 19 out of 26 patients [median (range): 8 (3-19) months]. Event-free survival was significantly longer (P = 0.001) in patients who maintained virological suppression than in those who did not have a complete virological response or suffered a breakthrough. Patients with advanced cirrhosis were more likely to develop liver failure after the emergence of YMDD mutants. The risk of development of hepatocellular carcinoma in patients with compensated cirrhosis and YMDD mutations was maintained, regardless of HBV-DNA serum levels. Profound and maintained HBV-DNA suppression correlates with a better outcome. Early identification of LAM resistance mutations allows switching to other antivirals before liver decompensation or hepatocellular carcinoma development
The ever changing moods of calmodulin: how structural plasticity entails transductional adaptability.
Prevalence of myocardial bridging and correlation with coronary atherosclerosis studied with 64-slice CT coronary angiography.
PURPOSE:
This study aimed to assess the prevalence and characteristics of myocardial bridging in patients who underwent multislice computed tomography coronary angiography (MSCT-CA) and to evaluate the correlation between bridged coronary segments and atherosclerosis.
MATERIALS AND METHODS:
A total of 277 patients (mean age 60+/-11 years) we consecutively examined with 64-slice MSCT-CA for suspected or known coronary atherosclerosis were retrospectively reviewed for myocardial bridging. Segments proximal and distal to the bridging were evaluated for atherosclerotic plaque, as were the remaining coronary segments.
RESULTS:
Myocardial bridging was present in 82 patients (30%, mean age 59+/-12). Bridges were of variable length (2 cm 10%) and depth (superficial 69%, intramyocardial 31%) and frequently localised in the mid-distal segment of the left anterior descending artery (95%). Myocardial bridging cannot be considered a significant risk factor for coronary atherosclerosis (odds ratio 0.49) compared with traditional cardiovascular risk factors. Coronary segments proximal to the bridge showed no atherosclerotic disease (33%), positive remodelling (27%), 50% stenosis (20%). We identified 12 noncalcified, 32 mixed and 17 calcified plaques. The distal segments were significantly less affected (p<0.0001).
CONCLUSIONS:
MSCT-CA is a reliable, noninvasive method that is able to depict myocardial bridging and associated atherosclerotic plaque in the proximal segments
