Induction of epoxide hydrolase, glucuronosyl transferase, and sulfotransferase by phenethyl isothiocyanate in male wistar albino rats.
Abstract
Phenethyl isothiocyanate (PEITC) is an isothiocyanate found in watercress as the glucosinolate (gluconasturtiin). The isothiocyanate is converted from the glucosinolate by intestinal microflora or when contacted with myrosinase during the chopping and mastication of the vegetable. PEITC manifested protection against chemically-induced cancers in various tissues. A potential mechanism of chemoprevention is by modulating the metabolism of carcinogens so as to promote deactivation. The principal objective of this study was to investigate in rats the effect of PEITC on carcinogen-metabolising enzyme s...

Domestically Acquired Fascioliasis in Northern California.
Abstract
Two cases of domestically acquired fascioliasis are reported. Patient One was a 63-year-old male who developed a febrile illness 2 months after eating watercress in Marin County. Patient Two was a 38-year-old male who had eaten watercress with Patient One, and also developed a febrile illness. Both patients had eosinophilia and liver lesions on imaging. Diagnosis was made by serology and treatment was with triclabendazole.

Dietary exposure to essential and potentially toxic elements for the population of Hanoi, Vietnam.
Abstract
Knowledge of the dietary intake of essential and toxic elements in fast-developing Southeast Asian countries such as Vietnam is limited. Iron and Zn deficiency in Asia is a well-known problem and is partly due to rice constituting a major part of the diet. Dietary habits are changing and there is a need to build more knowledge so authorities can give dietary recommendations. The aim of this study was to determine the total dietary intake of essential and potentially toxic elements and to assess the nutritional quality and food safety risks of the average Hanoi diet. Twenty-two foods or food groups...

Assessment of the Phytotoxicity of Seaport Sediments in the Framework of a Quarry-Deposit Scenario: Germination Tests of Sediments Aged Artificially by Column Leaching.
Abstract
The aim of the Sustainable Management of Sediments Dredged in Seaports (SEDIGEST) project is to assess the risks of treated port sediments for terrestrial ecosystems when deposited in quarries. We simulated the "ageing" of these sediments up to the "moment" when plants can germinate. Sediments were leached by water percolating through a laboratory column. Sediments 1 and 2, taken from the port of Toulon (France), were dried and aired. Sediment 3, taken from the port of Guilvinec (France), was stabilised with lime. Phytotoxicity was evaluated on the three artificially aged sediments using germinati...

Safety of Ready‐to‐Eat Watercress Using Environmentally Friendly Sanitization Methods
This study focused on the assessment of immersion in three chemical‐sanitizer solutions (sodium hypochlorite, hydrogen peroxide and citric acid) or the exposure to ultraviolet C (UV‐C) light in combination with modified atmosphere packaging and refrigerated storage (5C and 95% relative humidity). The evaluated disinfection methods resulted as or more effective at reducing microbial growth than chlorine washing. The UV‐C treatments improved the functional quality of watercress by increasing the total antioxidant capability and total polyphenol content. The implementation of low cost sanitization methods such as the te...
