OBJECTIVE We surveyed the datasheets of 29 laboratories concerning prenatal diagnosis of de novo apparently balanced chromosome rearrangements to assess the involvement of specific chromosomes, the breakpoints distribution and the impact on the pregnancy outcome. METHOD By means of a questionnaire, data on 269.371 analyses performed from 1983 to 2006 on(More)
Cytogenetic analysis of primary cell cultures from human atherosclerotic fibrous plaques revealed clonal chromosome abnormalities in 13 of the 18 cases studied. Loss of the Y chromosome and del(13)(q14) were present as single clonal abnormalities in eight cases; in five cases separate clones were found involving loss of the Y and a XXY karyotype, trisomy 10(More)
Keratinocytes are potential targets of lipid peroxidation products (alpha,beta-unsaturated aldehydes) generated in the skin following UV exposure, among which the most abundant and toxic product is 4-hydroxy-trans-2,3-nonenal (HNE). The aim of this study was to investigate the ability of keratinocytes (NCTC2544 cell lines) to detoxify HNE, through(More)
The T antigen (TAg) coding sequences of two DNA tumor viruses, BKV and SV40, were detected by Polymerase Chain Reaction (PCR) amplification followed by Southern-blot hybridization in two human glioblastoma multiforme derived cell lines. RT-PCR analysis indicated that these two TAg coding sequences were expressed in both tumor cell lines carrying the viral(More)
Endogenous lipid peroxidation (LPO)-derived aldehydes accumulate in human skin after photoexposure and contribute to the development of skin cytotoxicity and cancer. This study employed LC-ESI-MS and HPLC-UV-DAD techniques to investigate the effect of UVB radiation on the biotransformation and detoxification of the prototype aldehyde(More)
The karyotype of a new tumorigenic Kaposi sarcoma (KS)-derived cell line, as defined by cytogenetic and fluorescence in situ hybridization (FISH) analysis is 49,XY,i(1)(q10),i(7)(p10),+i(7) (q10),+der(8)t(8;13)(p11;q11),-13,+del(14)(q22),+der(17)t(1;17)(p13;p13). Our aim was to point out some characteristics and recurrent chromosome changes probably playing(More)
Ferulic acid (FA) is a well-known antioxidant of natural source with promising properties as photoprotective agent (approved in Japan as sunscreen) and its derivatives (alkyl ferulates) are under screening for the prevention of photoinduced skin tumours. In the present work we describe the preparation of a solid inclusion complex between ferulic acid and(More)
Cytogenetic studies of benign prostatic hyperplasia (BHP) are scarce. We analyzed primary cell cultures obtained from biopsies of prostatic tissues from 10 patients (mean age: 60.7 years) with histologic diagnosis of BHP to compare the eventual chromosome changes with those reported in prostatic adenocarcinoma. Clonal chromosome abnormalities were noted in(More)
Cytogenetic studies on 31 human meningiomas revealed clonal abnormalities in 14 of them. Monosomy 22 was present in three cases as the only abnormality, and in five it was associated with monosomy 18, monosomy 14, loss of X, loss of Y, and trisomy 20, respectively. We found a number of rearrangements involving chromosome #22: an i psu(More)
A new case of a de novo trisomy 10cen-->10pter is described. The karyotype was exactly defined by high resolution banding and FISH analysis; the chromosome aberration was of maternal meiotic origin as demonstrated by RFLP analysis. Clinical data are reported and correlated with other trisomy 10p cases from the literature. A critical review of the literature(More)
