It has recently been demonstrated that specific adrenoceptors subtypes (α1A/α1D) are prevalent in the distal part of the ureter, a finding supporting the interesting results obtained by different groups with the use of tamsulosin in the treatment of distal ureteral calculi. We performed a prospective randomized study to evaluate the effects of the addition(More)
MicroRNAs are small non-coding RNAs that modulate gene expression at post-transcriptional level, playing a crucial role in cell differentiation and development. Recently, some reports have shown that a limited number of mammalian microRNAs are also involved in anti-viral defense. In this study, the analysis of the hepatitis B virus (HBV) genome by the(More)
Under physiological salt conditions double-stranded (ds) RNA is resistant to the action of most mammalian extracellular ribonucleases (RNases). However, some pancreatic-type RNases are able to degrade dsRNA under conditions in which the activity of bovine RNase A, the prototype of the RNase superfamily, is essentially undetectable. Human pancreatic(More)
Nutrient concentrations (orthophosphate, orthosilicate and dissolved inorganic nitrogen-DIN) were measured on three transects in the northern Adriatic approximately monthly in the period June 1999-July 2002. The net nutrient transports across the three transects were estimated from these concentration values and calculated water fluxes [Grilli F, Paschini(More)
Ribonuclease A (RNase A) dimers have been recently found to be endowed with some of the special, i.e., non-catalytic biological activities of RNases, such as antitumor and aspermatogenic activities. These activities have been so far attributed to RNases which can escape the neutralizing action of the cytosolic RNase inhibitor (cRI). However, when the(More)
To study in HBsAg chronic carriers the expression of liver hsa-miR-125a-5p and its correlation with liver HBV-DNA values and clinical presentation, 27 consecutive Caucasian, HBsAg/anti-HBe/HBV-DNA-positive patients who were naive to nucleos(t)ide analogues and interferon therapy and had no marker of HCV, HDV or HIV infection and no history of alcohol intake(More)
The hepatitis B virus (HBV) is a widespread human pathogen and chronic HBV infection is a major risk factor for hepatocellular carcinoma (HCC). Some cellular microRNAs are emerging as important regulators of virus-host interaction, indirectly or directly modulating HBV replication and pathogenesis. miR-125a binds the viral transcript encoding the surface(More)
Dicer is a ribonuclease playing a key role in the biogenesis of microRNAs and small interfering RNAs. Here we report the identification of a novel splice variant of human dicer gene, the first one bearing a modified coding sequence. It encodes a truncated protein, t-Dicer that lacks the dsRNA-binding domain and is defective in one of the two RNase III(More)
Mussels are widely used as bioindicator organisms for monitoring chemical pollutants including trace metals. These elements are natural constituents in the marine environment and their basal concentrations in the organisms can be influenced by several environmental and biological factors. The aim of this work was to extend our knowledge on the natural(More)
The RNase H domain of human hepatitis B virus (HBV) polymerase is an attractive molecular target for the development of new anti-HBV drugs. In this study, a synthetic gene coding for HBV RNase H was assembled from 12 oligonucleotides and expressed in Escherichia coli. The encoded protein was then recovered from inclusion bodies, purified, and refolded by a(More)
