	abstract = {we studied the arsenic speciation in human urine samples by using high-performance liquid chromatography-inductively coupled plasma-mass spectrometry (HPLC-ICP-MS). We investigated the arsenic speciation in the urine collected from nine volunteers during a 3-day period after a meal of blue mussels, Mytilus edulis. We also studied the effect of cooking on the arsenic speciation. Arsenobetaine and dimethylarsinic acid (DMAA) were the major arsenic metabolites found in the urine samples. Significant amounts of unknown metabolites were also detected. The excretion patterns of arsenic from individuals were generally similar except for two subjects. One of whom excreted high amounts of arsenobetaine even though no arsenic-rich food was eaten for 3 days before the experiment. The results reveal that we need a better understanding of the metabolism of arsenic compounds by human. (C) 2004 Elsevier Inc. All rights reserved.},

	abstract = {The concentrations of total arsenic and arsenic species in the complete organism of the crayfish Procambarus clarkii and its various parts (hepatopancreas, tail, and remaining parts) were analyzed in order to discover the distribution of arsenic and its species. With this information it will be possible to establish where the chemical forms of this metalloid tend to accumulate and what risks may derive from the contents and species present in the edible parts of this crustacean. The total arsenic content in the complete organism and in the various parts analyzed ranged from 2.5 to 12 mug g(-1) dry mass (DM), with inorganic arsenic representing 18 to 34\% of total arsenic. The arsenical composition varied according to the part of the crayfish considered. The hepatopancreas had the highest levels of total arsenic (9.2-12 mug g(-1) DM) and inorganic arsenic (2.7-3.2 mug g(-1) DM). The tail (edible part) had the lowest levels of both total arsenic (2.5-2.6 mug g(-1) DM) and inorganic arsenic (0.46-0.64 mug g(-1) DM). The predominant organoarsenical species were the dimethylarsinoylribosides: glycerol riboside in the hepatopancreas, sulfate riboside in the tail, and sulfonate and phosphate ribosides in the remaining parts.

	abstract = {Chlorophylls, the green pigments responsible for photosynthesis in plants, algae and bacteria, are also part of the daily diet of herbivorous feeders. Numerous metabolic derivatives of the major green pigment, chlorophyll-a, have been found in a wide variety of organisms during the last decade. Studies of these metabolites show that some are antioxidants or cellular signaling mediators in vivo. The metabolites of bacteriochlorophylls-c and d, recently found in the deep-sea dragon fish, Malacosteus niger, function as a visual photosensitizer, enabling the fish to seek their prey in {\textquoteright}the dark{\textquoteright}. Discovery of these metabolites as well as their interesting biological functions raises questions as to the roles of chlorophyll derivatives in the chemical ecology of herbivorous life forms.

	abstract = {The reaction of Cl atoms with intrinsic an n+-doped polycrystalline silicon has been studied at a Cl partial pressure of 0.17 Torr and in the temperature ranges from 150 to 290-degrees-C and 25 to 90-degrees-C for the two materials, respectively. The reaction with n+-doped silicon was observed to proceed 90 times faster than with intrinsic silicon at any given temperature, i.e., within experimental error the difference in the rate constants for the two materials was found to be entirely attributable to a change in the pre-exponential factor, with the activation energy remaining unchanged. The rate constant for the reaction is given by (9 +/- 2) x 10(5) nm min-1 Torr(-1 exp-28.2 +/- 1.2 kJ/mol)/RT for the intrinsic material and (7 +/- 3) x 10(7) nm min-1 Torr exp-(27.8 +/- 1.5 kJ/mol)/RT for the phosphorus doped material with a dopant density of 5 x 10(18) cm-3.},
