(AMER SOC BIOCHEMISTRY MOLECULAR BIOLOGY INC, 2007-10-02)Acidithiobacillus ferrooxidans is a chemolithoautotrophic acidophile capable of obtaining energy by oxidizing ferrous iron or sulfur compounds such as metal sulfides. Some of the proteins involved in these oxidations ...
-
(Elsevier, 2010)We herein report on the group electrophilicity of molecular fragments present in the title compounds to describe leaving group abilities in reactions of aryl benzoates toward CN . It is found that the presence ...
-
(2002)High molecular weight (HMW, >15 kDa) but not low molecular weight (LMW, <15 kDa) polylysines (PLs) bound and induced permeability changes in rat spermatid plasma membranes, estimated by Mn2+ quenching of intracellular ...

Peroxisomal and microsomal fatty acid oxidation in liver of rats after chronic ethanol consumption (1998)1. Microsomal P450 and peroxisomal fatty acid oxidation activities were studied in liver of rats after long-term ethanol consumption. 2. Ethanol increased the microsomal lauric acid ω-hydroxylation and the aminopyrine ...

Peroxisome Proliferator-activated Receptors and Alzheimer's Disease: Hitting the Blood–Brain Barrier (Springer, 2013)The blood–brain barrier (BBB) is often affected in several neurodegenerative disorders, such as Alzheimer's disease (AD). Integrity and proper functionality of the neurovascular unit are recognized to be critical for ...
-
(Sociedad de Biologia de Chile, 2017)© The Author(s). 2017. Background: Monitos del monte (Dromiciops gliroides) are old-growth forest specialists and, thus, believed to be very sensitive to habitat transformation, although some recent studies show some level ...

(1984)We consider systems of differential equations of the form (1) x’ = f(t,x), for t ∊ [a,∞), x in some domain D ⊂ IRn and f ∈ c1 ([a,∞) × D) (a a fixed real number). We assume that the solution x(t,to,xo) of (1) defined for ...

(Springer International Publishing, 2017)© 2017, Springer International Publishing Switzerland. In addition to natural stressors such as predation risk, aquatic organisms receive the simultaneous impact of anthropogenic stressors like pollution. In order to advance ...
-
(Elsevier, 2013)tIn mammals, adaptation to chronic hypoxia requires the integrity of the arterial chemoreceptors, speciallythe carotid body (CB). Chronic hypoxia increases the sensibility of the CB by acting on the receptorcells, but there ...

(1990)The IR spectra of nitrobenzene-do and -ds were recorded in gas and liquid phases at 25° C and in amorphous solid phase at -170°C. The appearance of new bands and intensity changes going from liquid to solid phase spectrum, ...
-
(1981)The Falicov‐Ramirez‐Kimball model is solved by means of the two‐atom cluster Caron‐Pratt approximation. Metallic and insulating phases according to the value of an order parameter Δ are obtained, and both second‐ and ...
-
(IEEE, 2016)Surface plasmon polaritons (SPPs) are coherent electromagnetic surface waves trapped on an insulator-conductor interface. The SPPs decay exponentially along the propagation due to conductor losses, restricting the SPPs ...
-
(Blackwell Publishing Ltd, 2000)The behavior of substorms as sudden transitions of the magnetosphere is studied using the Bargatze et al. [1985] data set of the solar wind induced electric field vBs and the auroral electrojet index AL. The data set is ...
-
(1992)To understand the taxonomic and phylogenetic relationships of Alsodes montanus and A. pehuenche the species were compared with species of the genera Alsodes and Telmatobius. Comparisons were based on internal and external, ...
-
(MDPI, 2016)Mass spectrometry has become a method of choice to characterize bioactive compounds in biological samples because of its sensitivity and selectivity. Hybrid ultra-HPLC hyphenated with Orbitrap mass analyzer is an innovative ...
-
(Verlag der Zeitschrift fur Naturforschung, 2001)Pinocembrin, acacetin, galanguin, izalpin, kaempferide, prenyletin and diarytheptane were isolated from propolis from Central Chile.
-
(Springer, 2014)BACKGROUND: Frugivorous birds are phenologically linked to the fruits that they eat. When there is less fruit in seasonal environments, frugivorous birds complement their diet by eating invertebrates. The depth of the ...

(SOC BIOLGIA CHILE, 2009-10-21)Los bosques de la ecorregión subantártica de Magallanes incluyen una alta diversidad de briofitas, superando la diversidad de las plantas vasculares. A pesar de esto, estudios biológicos referentes a fenología de briofitas ...
-
(Springer-Verlag, 2010)We present herein a model to deal with the chemical reactivity, selectivity and site activation concepts of p electron systems derived by merging the classical Coulson–Longuet-Higgins response function theory based on ...
