EfavirenzIncrease in birth defects, 7 but certain ARV drugs may be toxic for pregnant women and fetuses. The drug efavirenz EFZ ; , for example, is believed to be a potent early teratogen, and recent World Health Organization WHO ; draft guidelines state that "EFZ should not be given to women of childbearing potential unless effective contraception can be assured."8 Other concerns have been raised about whether a woman's use of nucleoside reverse transcriptase inhibitors such as zidovudine and lamivudine ; could affect the mitochondrial or nuclear DNA of her child, potentially causing such side effects as lactic acidosis and anemia and increasing susceptibility to cancer.9. In addition, they were randomized to 1 of treatment arms that included either efavirenz efv, sustiva, stocrin ; , efavirenz plus indinavir idv, crixivan ; , or ritonavir rtv, norvir ; plus indinavir.

And filtered to remove particulate matter. The structures of these metabolites were determined from proton and carbon 1-dimensional NMR as well as proton-proton two dimensional correlated spectroscopy, proton-carbon heteronuclear multiple quantum correlation HMQC ; , and long range proton-carbon heteronuclear multiple bond correlation HMBC ; 2-dimensional NMR using a 400 MHz Varian VXR4S instrument. Liquid Chromatography NMR. 1H-LC NMR was performed using a Bruker AMX-500 MHz NMR spectrometer equipped with a dedicated 1H flow-probe probe flow cell of 4 mm i.d. with a volume of 120 l ; . Stoppedflow 1H-NMR spectra were obtained at 500 MHz using a modified one dimensional version of the nuclear Overhauser effect Spectroscopy NOESY ; pulse sequence for solvent peak presaturation, which produced conditions for ensuring double solvent suppression. Stopped-flow spectra were acquired using 256 or 512 transients with 64K data points and a spectral width of 12, 000 Hz. HPLC was performed using a Bruker LC22C pump and LC313 variable wavelength detector. The outlet of the UV detector was connected to the HPLC-NMR probehead via an inert polyethylether ketone PEEK ; capillary 0.25 mm i.d. ; . HPLC was performed on a C18 column 250 4.6 mm, 5 m ; using a gradient elution consisting of two components: A ; 0.1% TFA deuterated ; in D2O and B ; acetonitrile, Pestnal analytical grade, Riedel deHaen, Germany ; . The gradient consisted of increasing the percentage of B from 18 to 30 min followed by another increase to 40% B in 5 min. The flow rate was set at 1.0 ml min. The urine extract from solid phase extraction SPE ; cartridges containing the metabolite of interest, M1, was injected onto a HPLC column and 1H-LC NMR data was obtained. In Vitro Studies Preparation of Liver and Kidney Subcellular Fractions. The S9 and cytosolic fractions of livers and kidney were prepared from Sprague-Dawley rats 280 290 g b.wt. ; . The liver microsomes were prepared from rats treated with either phenobarbital PB ; or efavirenz. The rats were allowed food and water ad libitum before sacrifice. For the preparation of subcellular fractions, rats were treated with PB once a day for 3 days 75 mg kg i.p. ; or with efavirenz twice a day for 7 days 50 mg kg p.o. ; . Rats treated with saline served as controls. The animals were sacrificed by cervical dislocation 24 h after the last administration of either drug or saline and the livers and kidneys were removed. The livers and kidneys of cynomolgus monkeys were obtained from Hazelton Texas Primate Center Alice, TX ; . The 9000g S9 ; , cytosol, and microsomal fractions of rats and cynomolgus monkeys were prepared as described by Lake 1987 ; . The concentrations of proteins of the subcellular fractions were measured by the Lowry method Lowry et al., 1951 ; . The microsomal cytochrome P-450 activity was assessed by testosterone hydroxylation assay Sonderfan et al., 1987 ; . The S9 fractions of human livers and kidneys were purchased from either XenoTech Kansas City, KS ; , or from the International Institute for the Advancement of Medicine Exton, PA ; . The activity of glutathione-S-transferases GSTs ; in the subcellular fractions was evaluated by either spectrophotometric assay of the reaction of GSH with 1, 2-dichloronitrobenzene Habig et al., 1974 ; or by LC monitoring of the formation of S- p-nitrobenzyl ; GSH using p-nitrobenzyl chloride as the substrate see below ; . LC MS Assay for GST Activity. A LC MS technique was developed to assay GST activity using p-nitrobenzyl chloride as the substrate. The incubation consisted of 1 mM p-nitrobenzyl chloride and 5 mM GSH in a final volume of 1 ml 0.1 M phosphate buffer pH 6.5 ; . The reaction was initiated by the addition of 1 mg of S9 proteins. The incubation was performed at 37C for 15 min. An incubation with heat-deactivated S9 proteins was included as a control. The incubation was quenched by the addition of 2 ml ice-cold acetonitrile, and the mixture was centrifuged at 1450g for 10 min. The supernatant was removed and diluted with 1 ml of water and loaded onto a C18 cartridge 500 mg 3 ml ; previously conditioned with methanol and water. After the sample had eluted under gravity, the cartridge was sequentially washed with 1 ml of water and 1 ml of 5% methanol in water. The products were eluted from the cartridge with 2 ml of 70% methanol in water. The volume of the eluent was reduced to half under nitrogen at 30C and aliquots were injected onto the LC MS to detect the presence of GSH adducts. HPLC was performed on a small bore column YMC C18-AQ, 2 100 mm, 3 m ; with an isocratic mobile phase consisting of a mixture of acetonitrile and 10 mM ammonium.

The tellurium hypothesis Larner A.J. University of Cambridge, Department of Anatomy, Downing Street, Cambridge CB2 3DY United Kingdom Medical Hypotheses United Kingdom ; , 1995, 44 4 ; The efficacy of garlic as a lipid-lowering agent is being increasingly recognized, but the biochemical mechanisms underlying this action are currently unknown. It is proposed that organic tellurium compounds, which are found in high concentration in fresh garlic buds, may contribute to this action by inhibiting squalene epoxidase, the penultimate enzyme in the synthetic pathway of cholesterol . Weanling rats fed a diet rich in tellurium develop a demyelinating polyneuropathy due to inhibition of this enzyme in peripheral nerves. Chronic exposure to small amounts of tellurium found in garlic might reduce endogenous cholesterol production through inhibition of hepatic squalene epoxidase and so reduce cholesterol levels. Tellurium may also contribute to the characteristic 392. 2.1. Ammonite taxa Palaeontological data for the Callovian come from the different ammonite collections by Sequeiros, Lardis loc. cit. ; and the present authors. Oxfordian ammonites come from collections by Melndez; Fontana; Bello loc. cit. ; , and also from recent collections by the present authors. Detailed taxonomic data, at a species-level, constitute the base for the biostratigraphic analysis. In order to present these data in a more simplified way, they have been quantified at a genus or subfamily level besides suborder Phylloceratina ; , in the following way: Oppeliids, including Callovian genera: "Hecticoceras", Oxycerites, Paralcidia, Paroecotraustes, and Oxfordian Neocampylites, Trimarginites, Glochiceras, Taramelliceras including Proscaphites ; , and Ochetoceras. Tulitidae genus: Bullatimorphites ; , Macrocephalitidae; Reineckeiidae; Perisphinctidae, including Callovian genera Homoeoplanulites and Grossouvria, and Oxfordian Perisphinctes, Prososphinctes, and Larcheria Perisphinctinae ; and Passendorferia and Sequeirosia Passendorferiinae Aspidoceratidae genus Euaspidoceras ; . 2.2. Taphonomic features Taphonomic analysis of ammonite recorded associations has been carried out following the model established by Fernndez-Lpez and Surez Vega 1981 ; and Fernndez-Lpez 1985a, b, 1995, 1997 ; . Taphonomic features displayed by ammonites are categorised following a succession which would, in fact, correspond with an increasing turbulence and shallowing gradient, from complete, peristomed shells Ps ; to fragmented internal moulds Fm ; or mould fragments Mf ; see Figs. 4-7 ; . Complete or fragmented shells are, normally, resedimented elements i.e. displaced on the sea bottom and or fragmented before burial ; . Fragmented, disarticulated or faceted internal moulds are generally reelaborated fossils, undergoing taphonomic reworking reelaboration ; , i.e. a process of exhumation and displacement on the substrate, after the initial burial. Disarticulation surfaces and abrasion facets, such as, roll facets; truncation facets, ellipsoidal facets or annular furrows are particular reelaboration features typically revealing reelaboration see Fernndez-Lpez, 1985a; FernndezLpez and Melndez, 1994 ; . The key to the plotted taphonomic features is as follows: S: Resedimented elements. W: Reelaborated elements Conc: Concentration of ammonites. The increasing degree of concentration of fossils resedimented shells or reelaborated moulds ; may be connected with decreasing and ethambutol.
