Toxicokinetic Modeling of the Combined Exposure to Toluene and n-Hexane in Rats and Humans: Nabeel ALI, et al. Département de médecine du travail et d’hygiène du milieu, Faculté de médecine, Université de Montréal—We studied the toxicokinetic fate of toluene (TOL) and n-hexane (HEX) in rats exposed to mixtures of these solvents by inhalation during 4 hours. We developed and validated a physiolo...

Ten cadmium resistant marine bacterial isolates were isolated from seawater and sediments samples of Hurghada harbour on a seawater nutrient agar medium amended by 25 ppm of cadmium and tested for their resistance to higher cadmium concentrations (up to 200 ppm). The most resistant isolate which was able to grow at 150 ppm was identified on the basis of its morphological, physiological and bioc...

BACKGROUND & OBJECTIVES Development of insect resistance to synthetic pesticides, high operational cost and environmental pollution have created the need for developing alternative approaches to control vector-borne diseases. In the present study, larvicidal activity of flavonoid extracts of different parts of Vitex negundo (Linnaeus) and Andrographis paniculata (Nees) have been studied against...

The scotopic sensitivity, reaction time, eye movements, and visually evoked cortical potentials of 12 nonsmokers and 6 smokers were measured during the course of 3 hr of exposure both to air and to 200 ppm CO in air. No significant degradation in performance was observed for any of these measures in either group during the course of the exposure.

This article presents an energy-efficient dual- $RC$ frequency reference intended for wireless sensor nodes. It consists of a digital frequency-locked loop (FLL) in which the digitally controlled oscillator (DCO) is locked to temperat...

Nonsteroidal anti-inflammatory drugs (NSAID) have been highly effective in preventing colon, urinary bladder, and skin cancer preclinically, and also in clinical trials of colon adenoma formation. However, certain NSAIDs cause gastrointestinal ulceration and may increase cardiovascular events. Naproxen seems to cause the lowest cardiovascular events of the common NSAIDs other than aspirin. Nitr...

wnloaded creatic ductal adenocarcinoma (PDAC) is the most common pancreatic malignancy with a dismal osis. Developing novel strategies to prevent or delay pancreatic cancer is currently of intense intere chemopreventive efficacy of gefitinib, an epidermal growth factor receptor (EGFR) inhibitor, was ted against the progression of pancreatic intraepithelial neoplasms (PanIN) to PDAC in condition...

Adipose tissue is responsive to estrogen and expresses both estrogen receptor alpha and beta. To test the hypothesis that the estrogenic soy isoflavone genistein can have effects on adipose tissue, juvenile or adult C57/BL6 mice were ovariectomized and given daily injections of vehicle, 17beta-estradiol (5 microg/kg.d) or genistein (8-200 mg/kg.d) sc for 21-28 d. To test effects of dietary geni...
