In vitro genomic damage caused by glyphosate and its metabolite AMPA.

Glyphosate is the most widely used systemic herbicide. There is ample scientific literature on the effects of this compound and its metabolite aminomethylphosphonic acid (AMPA), whereas their possible combined genotoxic action has not yet been studied. With the present study, we aimed to determine the level of genomic damage caused by glyphosate and AMPA in cultured human lymphocytes and to investigate the possible genotoxic action when both compounds were present at the same concentrations in the cultures.

Cellular and Genomic Instability Induced by the Herbicide Glufosinate-Ammonium: An In Vitro and In Vivo Approach.

Glufosinate-ammonium (GLA), an organophosphate herbicide, is released at high concentrations in the environment, leading to concerns over its potential genotoxic effects. However, few articles are available in the literature reporting the possible cellular and nuclear effects of this compound. We assessed, by in vitro and in vivo micronucleus assays, the genotoxicity of GLA on cultured human lymphocytes and hemocytes at six concentrations: 0.

Genotoxicological and physiological effects of glyphosate and its metabolite, aminomethylphosphonic acid, on the freshwater invertebrate Lymnaea stagnalis.

Aminomethylphosphonic acid (AMPA) is the main metabolite in the degradation of glyphosate, a broad-spectrum herbicide, and it is more toxic and persistent in the environment than the glyphosate itself. Owing to their extensive use, both chemicals pose a serious risk to aquatic ecosystems. Here, we explored the genotoxicological and physiological effects of glyphosate, AMPA, and the mixed solution in the proportion 1:1 in Lymnaea stagnalis, a freshwater gastropod snail.

Zygomycosis in Italy: a survey of FIMUA-ECMM (Federazione Italiana di Micopatologia Umana ed Animale and European Confederation of Medical Mycology).

The aims of the study were to analyze the clinical and epidemiological characteristics and treatments for patients who developed zygomycosis enrolled in Italy during the European Confederation of Medical Mycology of medical mycology survey. This prospective multicenter study was performed between 2004 and 2007 at 49 italian Departments. 60 cases of zygomycosis were enrolled: the median age was 59.

Phenotypic and genotypic characterization of Neisseria gonorrhoeae in parts of Italy: detection of a multiresistant cluster circulating in a heterosexual network.

Data concerning Neisseria gonorrhoeae infections in Italy are scarce, and there is little information on the phenotypic and genotypic characteristics of the circulating strains. In this study, 326 isolates collected from 397 patients, with or without concurrent human immunodeficiency virus (HIV) infection, were cultured and characterized by serovar and antimicrobial susceptibility to five antimicrobials. N.

[Vaginitis caused by Eikenella corrodens].

The Authors report a case of vaginitis caused by Eikenella corrodens (E.C.) and point out it is very rare all over the world (probably the first case reported in Italy).

T gamma cell deficiency in idiopathic thrombocytopenic purpura (ITP).

A significant reduction in the proportion and absolute number of circulating T gamma (suppressor) lymphocytes was observed in 15 adult patients with idiopathic thrombocytopenic purpura (ITP). The proportion of T gamma cells was also reduced in the spleen of four patients so investigated. This abnormality was not seen in 5 patients cured by splenectomy whilst it persisted in 3 who remained thrombocytopenic after splenectomy.
