Mercury toxicity in plants
Mercury poisoning has become a problem of current interest as a result of environmental pollution on a global scale. Natural emissions of mercury form two-thirds of the input; manmade releases formExpand

Comparison of mercury, lead and arsenic with respect to genotoxic effects on plant systems and the development of genetic tolerance
Metals can, when present in excess, or under wrong conditions, and in the wrong places, produce errors in the genetic information system. The present review is limited to three examples of heavyExpand

Differential gene expression in Daphnia magna suggests distinct modes of action and bioavailability for ZnO nanoparticles and Zn ions.
Zinc oxide nanoparticles (ZnO NPs) are being rapidly developed for use in consumer products, wastewater treatment, and chemotherapy providing several possible routes for ZnO NP exposure to humans andExpand

A new strategy for the prevention of Clostridium difficile infection.
BACKGROUND Clostridium difficile infection (CDI) is a leading cause of antibiotic-associated diarrhea. The infective form of C. difficile is the spore, but the vegetative bacterium causes theExpand

Cooperativity and interference of germination pathways in Bacillus anthracis spores.
Spore germination is the first step to Bacillus anthracis pathogenicity. Previous work has shown that B. anthracis spores use germination (Ger) receptors to recognize amino acids and nucleosides asExpand

Challenges for physical characterization of silver nanoparticles under pristine and environmentally relevant conditions.
The reported size distribution of silver nanoparticles (AgNPs) is strongly affected by the underlying measurement method, agglomeration state, and dispersion conditions. A selection of AgNP materialsExpand

Changes in agglomeration of fullerenes during ingestion and excretion in Thamnocephalus platyurus.
The crustacean Thamnocephalus platyurus was exposed to aqueous suspensions of fullerenes C(60) and C(70) . Aqueous fullerene suspensions were formed by stirring C(60) and C(70) as received from aExpand

Search for a diagnostic/prognostic biomarker for the brain cancer glioblastoma multiforme by 2D-DIGE-MS technique
The prognosis of patients with glioblastoma multiforme, the most malignant adult glial brain tumor, remains poor in spite of advances in treatment procedures, including surgical resection,Expand

Fate of Ingested Clostridium difficile Spores in Mice
Clostridium difficile infection (CDI) is a leading cause of antibiotic-associated diarrhea, a major nosocomial complication. The infective form of C. difficile is the spore, a dormant and resistantExpand

Assessment of genotoxicity of inorganic mercury in rats in vivo using both chromosomal aberration and comet assays
The major objective of the present investigation was to assess the genotoxic effects of mercuric chloride (HgCl2), an inorganic mercury (Hg), in rats (Rattus norvegicus) using two different geneticExpand
