We identified 15 patients with acute hepatitis C (AHC) among 29 healthy volunteers participating in 2 consecutive pharmacokinetics studies. Molecular techniques were used to determine the relatedness of viral strains, whereas clinical and virologic follow-up was started to establish the course and outcome of the acute infection. After presentation, serum(More)
BACKGROUND AND AIMS Ulmus minor has been severely affected by Dutch elm disease (DED). The introduction into Europe of the exotic Ulmus pumila, highly tolerant to DED, has resulted in it widely replacing native U. minor populations. Morphological and genetic evidence of hybridization has been reported, and thus there is a need for assessment of(More)
Fish have the ability to compensate for set-backs in growth as a result of fasting. When food levels are restored, growth in these fish can increase over and above normal rates. This phenomenon, known as "compensatory growth", has been studied with respect to enhancing food conversion efficiency. However, the mechanisms by which food intake activates an(More)
BACKGROUND AND AIMS The assessment of the genetic variability and the identification of isolated populations within a given species represent important information to plan conservation strategies on a genetic basis. In this work, the genetic variability in five natural populations of Juniperus phoenicea, three from Sardinia, one from Cyprus and the last one(More)
In this report we present the characterization of ovarian neoplasms including benign tumors, borderline tumors, and invasive carcinomas in order to assess whether a sharing of cytogenetic abnormalities is present in all three types of tumors. A cohort of 114 newly diagnosed and untreated ovarian epithelial tumors were analyzed by cytogenetic and molecular(More)
Single nucleotide polymorphisms (SNPs) are becoming the most common type of markers used in genetic analysis. In the present report a SNP has been chosen to test the applicability of Real Time PCR to discriminate and quantify SNPs alleles on DNA pools. Amplification Refractory Mutation System (ARMS) and Mismatch Amplification Mutation Assay (MAMA) has been(More)
The C3H/He mouse represents a good experimental model of genetic predisposition to hepatocellular tumor development. We analyzed an interspecific test-cross population of 106 urethane-treated male (C3H/He x Mus spretus) x C57BL/6J mice, typed with 222 genetic markers to locate precisely the hepatocellular tumor susceptibility (Hcs) loci. Three regions, on(More)
Lung tumours represent a major cause of death in humans, and although smoking represents the main pathogenetic factor, inheritance also plays a part. However, the identification of possible predisposing genetic factors is difficult, because of their low penetrance. We took advantage of murine strains that are genetically susceptible or resistant to lung(More)
Numerous studies have demonstrated a link between genetic markers on chromosome 13 and schizophrenia, bipolar affective disorder, and other psychiatric phenotypes. The G72/G30 genes (transcribed in opposite directions) are located on chromosome 13q33, a region demonstrating strong evidence for linkage with various neuropsychiatric disorders. G72/G30 was(More)
The validity of mouse liver tumors is controversial in the risk assessment of carcinogenicity of chemicals in humans, because mice used in carcinogenicity bioassays are genetically predisposed to liver tumors. The argument could be resolved once liver tumor susceptibility genes have been cloned and their role in liver tumor development elucidated. We(More)
