Hereditary breast and ovarian cancer genetic testing in unselected patients: example of private supplementation of public healthcare service.

In the Emilia-Romagna region (Northern Italy), the identification and management of women at familial/hereditary risk of breast and ovarian cancer is guided by a well-established regional protocol. Here we report the results of the experience of private supplementation of public healthcare service in offering the possibility to undergo BRCA1/2 testing and/or multigene panel testing (MGPT) within a well-defined pathway to women unfulfilling regional criteria. Out of 177 patients referred to our center who underwent BRCA1/2 testing, 175 tested negative while two (1.

The Strategic Alliance between Clinical and Molecular Science in the War against SARS-CoV-2, with the Rapid-Diagnostics Test as an Indispensable Weapon for Front Line Doctors.

Our work concerns the actual problem of spread of SARS- CoV-2 outbreak which requires fast and correct as possible answer. In current scenario, the need of rapid answer put away the imperative of proper methodology. We focus on the serogical immunoassay for diagnosis of Covid-19 as an important weapon not only for diagnostic purpose, but also for epidemiologic one.

Activation of TRPC1 Channel by Metabotropic Glutamate Receptor mGluR5 Modulates Synaptic Plasticity and Spatial Working Memory.

Group I metabotropic glutamate receptors, in particular mGluR5, have been implicated in various forms of synaptic plasticity that are believed to underlie declarative memory. We observed that mGluR5 specifically activated a channel containing TRPC1, an isoform of the canonical family of transient receptor potential (TRPC) channels highly expressed in CA1-3 regions of the hippocampus. TRPC1 is able to form tetrameric complexes with TRPC4 and/or TRPC5 isoforms.

Core Microbiota and Metabolome of L. cv. Corvina Grapes and Musts.

The composition and changes of the fungal population and of the metabolites present in grapes and in ferments of L. cv. Corvina, one of the major components of the Amarone musts, were dissected aiming at the identification of constant characteristics possibly influenced by the productive process.

DNA-Based Taxonomy in Ecologically Versatile Microalgae: A Re-Evaluation of the Species Concept within the Coccoid Green Algal Genus Coccomyxa (Trebouxiophyceae, Chlorophyta).

Coccomyxa is a genus of unicellular green algae of the class Trebouxiophyceae, well known for its cosmopolitan distribution and great ecological amplitude. The taxonomy of this genus has long been problematic, due to reliance on badly-defined and environmentally variable morphological characters. In this study, based on the discovery of a new species from an extreme habitat, we reassess species circumscription in Coccomyxa, a unicellular genus of the class Trebouxiophyceae, using a combination of ecological and DNA sequence data (analyzed with three different methods of algorithmic species delineation).

Development of reliable analytical tools for evaluating the influence of reductive winemaking on the quality of Lugana wines.

This paper presents methods for the definition of important analytical tools, such as the development of sensitive and rapid methods for analysing reduced and oxidised glutathione (GSH and GSSG), hydroxycinnamic acids (HCA), bound thiols (GSH-3MH and Cys-3MH) and free thiols (3MH and 3MHA), and their first application to evaluate the effect of reductive winemaking on the composition of Lugana juices and wines. Lugana is a traditional white wine from the Lake Garda region (Italy), produced using a local grape variety, Trebbiano di Lugana. An innovative winemaking procedure based on preliminary cooling of grape berries followed by crushing in an inert environment was implemented and explored on a winery scale.

Comparison of ectomycorrhizal communities in natural and cultivated Tuber melanosporum truffle grounds.

Truffles are hypogeous ectomycorrhizal (EM) fungi belonging to the genus Tuber. Although outplanting of truffle-inoculated host plants has enabled the realization of productive orchards, truffle cultivation is not yet standardized. Therefore, monitoring the distribution of fungal species in different truffle fields may help us to elucidate the factors that shape microbial communities and influence the propagation and fruiting of Tuber spp.

Workplace bullying and psychotropic drug use: the mediating role of physical and mental health status.

Objectives: The association between workplace bullying and psychotropic drug use is not well established. This study was aimed at exploring the association between workplace bullying, and its characteristics, and psychotropic drug use and studying the mediating role of physical and mental health.

Methods: The study population consisted of a random sample of 3132 men and 4562 women of the working population in the south-east of France.

Workplace bullying and sleep disturbances: findings from a large scale cross-sectional survey in the French working population.

Study Objectives: The purpose of this study was to explore the associations between workplace bullying, the characteristics of workplace bullying, and sleep disturbances in a large sample of employees of the French working population.

Design: Workplace bullying, evaluated using the validated instrument developed by Leymann, and sleep disturbances, as well as covariates, were measured using a self-administered questionnaire. Covariates included age, marital status, presence of children, education, occupation, working hours, night work, physical and chemical exposures at work, self-reported health, and depressive symptoms.

Mild mental retardation in a child with a de novo interstitial deletion of 15q21.2q22.1: a comparison with previously described cases.

We report on a child with mild mental retardation, hypotelorism, blepharophimosis, face slight asymmetry and partial hypoplasia of corpus callosum, with an interstitial deletion of a chromosome 15. The deletion was molecularly characterized by array-CGH and FISH techniques. This rearrangement has a 7.

[The use of fluoroquinolone plasma levels by physicians].

Objective: To assess how physicians use the results of fluoroquinolone plasma concentrations.

Methods: A retrospective study was carried out on all the patients of the Infectiology department of the University Hospital in Nice who had undergone measurement of ofloxacin, ciprofloxacin or pefloxacin plasma levels between the 1st of January 2001 and the 31st of May 2002.

Results: Seventy eight patients were included.

[Escherichia coli bacteremic urinary tract infections. Clinical aspects and pronostic factors].

Objective: To describe patients with bacteremia from urinary tract infection caused by Escherichia coli and investigate risk factors for mortality.

Method: Retrospectively study of the files of patients with bacteremic urinary tract infection caused by E. coli and admitted via the Emergency Department of the University Hospital in Nice between 01/01/1997 and 12/31/2000.

Relevance and complications of intravenous infusion at the emergency unit at Nice university hospital.

Objective: Insertion of peripheral venous catheters (PVCs) is current practice within the hospital environment and particularly in the emergency department (ED). This simple yet invasive technique may result in venous thrombosis, infection or mechanical complications. We conducted a prospective study at the Nice University Hospital ED in order to determine the frequency, relevance and complications of peripheral venous cannulation.

Analysis of chromosome conservation in Lemur catta studied by chromosome paints and BAC/PAC probes.

A panel of human chromosome painting probes and bacterial and P1 artificial chromosome (BAC/PAC) clones were used in fluorescence in situ hybridization (FISH) experiments to investigate the chromosome conservation of the ring-tailed lemur (Lemur catta, LCA) with respect to human. Whole chromosome paints specific for human chromosomes 7, 9, 11, 13, 14, 17, 18, 20, 21, and X were found to identify a single chromosome or an uninterrupted chromosomal region in LCA. A large set of partial chromosome paints and BAC/PAC probes were then used to refine the characterization of the rearrangements differentiating the two karyotypes.

Evolutionary history of chromosome 10 in primates.

We have tracked the evolutionary history of chromosomes homologous to HSA10 (PHYL-10) in primates using appropriate panels of PCP, YAC, and BAC probes. This approach allowed us to delineate more precisely the PHYL-10 constitution in the ancestor of catarrhine, platyrrhine, and prosimians. The results suggest that (i) in the ancestor of prosimians PHYL-10 was organized in two separate PHYL-10p and PHYL-10q chromosomes; (ii) in the progenitor of New World monkeys PHYL-10p was a separate chromosome, while PHYL-10q was associated with a chromosome homologous to HSA16; (iii) in the ancestor of Old World monkeys PHYL-10 was a unique chromosome with a marker order corresponding to the orang form.

Differential divergence of three human pseudoautosomal genes and their mouse homologs: implications for sex chromosome evolution.

The human pseudoautosomal region 1 (PAR1) is essential for meiotic pairing and recombination, and its deletion causes male sterility. Comparative studies of human and mouse pseudoautosomal genes are valuable in charting the evolution of this interesting region, but have been limited by the paucity of genes conserved between the two species. We have cloned a novel human PAR1 gene, DHRSXY, encoding an oxidoreductase of the short-chain dehydrogenase/reductase family, and isolated a mouse ortholog Dhrsxy.

Prevalence and risk factors of cervicovaginal HIV shedding among HIV-1 and HIV-2 infected women in Dakar, Senegal.

Objectives: To assess the risk determinants and prevalence of cervicovaginal shedding of HIV-1 and HIV-2 among women in Dakar, Senegal.

Methods: We conducted a cross sectional study of 153 HIV seropositive female sex workers (FSW) and another 142 HIV seropositive women attending an infectious diseases unit, based on an interview, physical examination, and laboratory screening for major sexually transmitted infections (STI). Cervicovaginal lavage fluid was tested for HIV-RNA by means of nested PCR.

Centromere repositioning.

Primate pericentromeric regions recently have been shown to exhibit extraordinary evolutionary plasticity. In this paper we report an additional peculiar feature of these regions that we discovered while analyzing, by FISH, the evolutionary conservation of primate phylogenetic chromosome IX. If the position of the centromere is not taken into account, a relatively small number of rearrangements must be invoked to account for interspecific differences.
