(1997)From Mulinum crassifolium Phil, collected on the western flank in northern Chile, was isolated mulin-11,13-dien-20-oic acid and a new diterpenoid, 17-acetoxymulin-11,13-dien-20-oic acid 2. Its structure was established by ...

(Inst. Paleobiologii Pan, 2018)The contents of the superfamily Platanistoidea, an early-diverging lineage comprising extinct species and a single extant representative of South Asian river dolphin (Platanista gangetica), remain controversial. We describe ...

(Academic Press, 2014)A postcranial specimen from the lower Maastrichtian levels of the Conway Formation, Middle Waipara River, North Canterbury, New Zealand shows clear elasmosaurid affinities, based on the articular faces, with a ventral ...
-
(Blackwell Publishing Ltd, 2014)The amphibian genus Telmatobius is a diverse group of species that inhabits the Andes. This study analysed the phylogenetic relationships of 19 species described from the central Andes of Chile and Bolivia, and 12 undescribed ...
-
(2012)Here we show that the dynamic simulation of a molecular collision can give insight into new molecular species. In this way, a new stable isomer of C 20 (IV) has been found. It is planar with pentagonal form. This isomer ...

A new method of assessing rates of the futile cycle during glycolytic and gluconeogenic metabolism (1995)A method for assessing rates of the futile cycle is presented, and it is illustrated in vitro. Glycolytic- and gluconeogenic-type cycles are simulated for the reactions catalyzed by phosphofructokinase (EC 2.7.1.11) and ...

(Medknow Publications, 2014)Background: Azorella compacta is a rare yellow-green compact resinous cushion shrub growing from the high Andes of southern Peru to northwestern Argentina, and which is a producer of biologically active and unique diterpenoids. ...
-
(Copernicus Gesellschaft MBH, Germanyc, 2021)A new monotypic genus of Neogene odontocete (Isoninia borealis) is named on the basis of a partial skull (CMM-V-4061). The holotype was found on the riverbed of the Meherrin River (North Carolina, USA) and probably originated ...
-
(2012)Crepipatella occulta n. sp. is described from the intertidal zone in northern Chile. This species is morphologically cryptic with two other Crepipatella species from Chile, Crepipatella dilatata (Lamarck, 1822) and ...
-
(1987)Pristidactylus volcanensis, a new species from El Volcan, Cordillera de Los Andes, is distinguished by coloration, squamation, measurements, and habitus. -from Authors
-
(Elsevier, 2017)We describe isolated shark teeth collected from levels of the Calafate Formation at the SE coast of the Argentino Lake, Calafate city, Santa Cruz province, Argentina (Atlantic Ocean), and from the Algarrobo coast at the ...
-
(American Ornithological Society, 2013)We describe a new species of storm-petrel, Oceanites pincoyae (Pincoya Storm-Petrel), from the Puerto Montt and Chacao channel area, Chile. The description is based on 1 specimen collected at sea in Seno Reloncavi on 19 ...
-
(ACAD BRASILEIRA DE CIENCIAS, 2011-03)Partial remains of a titanosaur sauropod collected in the Tolar Formation (Upper Cretaceous) at the Atacama Desert (Antofagasta Region), northern Chile, is described, and a new species, Atacamatitan chilensis gen. et sp. ...
-
(Elsevier, 2017)A basic question concerning indecomposable Soergel bimodules is to understand their en-domorphism rings. In characteristic zero all degree-zero endomorphisms are isomorphisms (afact proved by Elias and the second author) ...
-
(Amer Geophysical Union, 2021)We propose a method, based on Neural Networks, that detects the nonlinear robust interplanetary solar wind variables, with varying delays, driving the coupled behavior of three geomagnetic indices (Dst, AL, and AU). As ...
-
(Springer, 2017)In this note we show that if an abelian variety possesses a Galois embedding into some projective space, then it must be isogenous to the self product of an elliptic curve. We prove moreover that the self product of an ...
-
(Marcel Dekker Inc., 1999)Let F be a field of any characteristic. For n ≥ 0, let J(n) = {q̄ ∈ Wq(F)| deg(q) ≥ n}. The degree conjecture asserts that for each n ≥ 0 (DC) J(n) = InWq(F) Let p be any n-fold quadratic Pfister form over F and F(p) the ...
-
(Elsevier, 2018)We propose a novel approach for the treatment of atrophic bone non-unions via parallel applications of extracorporeal shock wave therapy (ESWT) and an autologous mesenchymal stem cell transplant. The hypothesis resides on ...
