(1998)The effect of acetone consumption on some microsomal and peroxisomal activities was studied in rat kidney and these results were compared with data from former investigations in liver. Acetone increased the microsomal ...
-
(1998)The effect of defoliation on growth and on levels and allocation patterns of hydroxamic acids (Hx) in maize seedlings was evaluated 6 days after treatment. No significant differences were found between defoliated and ...
-
(Elsevier Ltd, 1997)The intercalation of poly(ethylene oxide) (PEO) in molybdenum sulfide (MoS2) forms the nanocomposites LixMoS2(PEO)0.5 and LixMoS2(PEO)1.0. The lithium ion diffusivity in PEO-containing phases, which depends on both PEO and ...
-
(Elsevier Ltd, 1997)The reaction rates for the intercalation of lithium in molybdenum and titanium sulfide activated by microwave irradiation at room temperature and atmospheric pressure leading to products of relatively high crystallinity ...
-
(1997)This work is concerned with the quasi-diagonalization of the impulsive linear systemx′=A(t)x,x(t+k)=Bkx(t-k), where the functionA(t) is bounded and piecewise uniformly continuous, and (Bk)∞k=1is a bounded sequence of impulse ...
-
(Elsevier Ltd, 1997)Discrete nonautonomous nonlinear systems possessing (h, k)-trichotomies are considered. We specialize to the case of solutions moving inside - and in a neighborhood of - an invariant manifold of a special kind, which we ...
-
(Ecological Society of America, 1997)The degu, Octodon degus (Rodentia, Octodontidae) is a diurnal herbivore inhabiting the semiarid and mediterranean environments of northern and central Chile. In the field, degus are constrained to specific foraging areas, ...
-
(Elsevier, 1997)The present status of the Brazilian AMS program, based on the University of São Paulo 8UD tandem accelerator, is described. Results of tests and developments on voltage stability, focusing, automatic system for changing ...
-
(1995)The proteins secreted by the male genital tract were analyzed in the seasonally breeding rodent Octodon degus. The protein patterns from the fluids collected from sexually active animals were compared with those from animals ...
-
(Springer New York LLC, 1997)Hydroxamic acids (Hx) are natural products of Gramineae that are associated with cereal resistance to pests. We aimed at characterizing the induction of Hx accumulation in seedlings of wheat. Triticum aestivum, by short-term ...
-
(1997)We report on a theoretical and numerical investigation of the switching of power in new hybrid models of nonlinear coherent couplers consisting of optical slab waveguides with various orders of nonlinearity. The first model ...
-
(1997)Microsomal cytochrome P450 and peroxisomal activity were studied in liver of rats 7 days after two-thirds hepatectomy or bile duct ligation (BDL). Both surgical models decreased the hepatic microsomal cytochrome P450 ...
-
(1997)1. Microsomal cytochrome P-450 and peroxisomal fatty acid oxidation was studied in the kidney of rats 7 days after bile duct ligation (BDL) and a comparative study between kidney and liver was done. 2. Only in the liver ...
-
(1997)Microsomal lauric acid hydroxylation and fatty acid peroxisomal β-oxidation were studied in hepatic subcellulant preparations from streptozotocin-induced diabetic and diabetic insulin-treated rats. The liver microsomes of ...
-
(1997)The tectofugal pathway is a massive ascending polysynaptic pathway from the tectum to the thalamus and then to the telencephalon. In birds, the initial component of this pathway is known as the tectorotundal pathway; in ...
-
(Springer New York LLC, 1997)The effects of temperature and photoperiod on accumulation of hydroxamic acids (Hx) in wheat (Triticum aestivum L.) seedlings were evaluated under laboratory conditions. Hx concentrations were significantly higher at higher ...
-
(1995)Tau proteins play major regulatory roles in the organization and integrity of the cytoskeletal network. In neurons, a specific axonal compartmentalization of tau has been shown. However, recent studies demonstrate that tau ...
-
(1997)We studied the effects of sodium nitroprusside, a nitric oxide donor, on the chemosensory responses to cyanide and nicotine in the cat carotid body. In situ, sodium nitroprusside infusion reduced the cyanide-evoked responses ...
-
(1997)In the Andes of Central Chile, flowering commences 1-2 months earlier on equatorial-(north-) facing than on polar- (south-) facing slopes, and pollinator assemblages also differ between these habitats. In order to understand ...
-
(University of California Press, 1997)An unusual pattern has been described in Patagonian forests, where bird species diversity seems to be inversely correlated with vegetation complexity. To test the occurrence of this pattern in the northern Nothofagus forests ...
