(1976)Following treatment for premature ejaculation, 23 males provided reports of sexual intercourse with females other than the one who had been a treatment partner. Analysis of the data strongly suggests that concomitant ...
-
(2007)We study commutative algebras which are generalizations of Jordan algebras. The associator is defined as usual by (x, y, z) = (x y)z - x(y z). The Jordan identity is (x2, y, x) = 0. In the three generalizations given below, ...
-
(Kluwer Academic Publishers, 2014)Flowers that are pollinated both during the day and at night could exhibit two different groups of pollinators and produce two different sets of attractants and rewards. We explored the patterns of emission of flower scents ...
-
(2007)Dendritic cells (DCs) are professional antigen presenting cells with the ability to induce and regulate an immune response. DCs that capture and present antigen under noninflammatory conditions maintain an immature phenotype ...

(Company of Biologists Ltd, 2018)© 2018. Published by The Company of Biologists Ltd. Xenografts of the hematopoietic system are extremely useful as disease models and for translational research. Zebrafish xenografts have been widely used to monitor blood ...
-
(2005)Protein kinase CK1 denotes a family of pleiotropic serine/threonine protein kinases implicated in a variety of cellular functions. Typically, CK1 acts as a 'phosphate-directed' kinase whose targeting is primed by a single ...
-
(Public Library Science, 2015)The extreme dependence on external oxygen supply observed in animals causes major clinical problems and several diseases are related to low oxygen tension in tissues. The vast majority of the animals do not produce oxygen ...
-
(2009)Background: Morphogenetic events that shape the Drosophila melanogaster embryo are tightly controlled by a genetic program in which specific sets of genes are up-regulated. We used a suppressive subtractive hybridization ...
-
(Magnolia Press, 2017)The genus Ectinogonia Spinola, 1837 is a genus mainly found in Chile; it currently contains 17 species. Recent exploration in the Andes Mountain Range of the Bio Bio Region in Chile have resulted in the collection of ...
-
(Taylor & Francis, 2017)Background: Reductions of genetic diversity and phenotypic changes in invasive plants are often observed to occur at high elevations. Genetic/phenotypic changes of invasive plants along elevation help to understand mechanisms ...
-
(2012)Mussels are one of the most cultivated and commercialized bivalves worldwide and in southern Chile its culture represent an important economic activity. The species identification within the Mytilus genera, by morphological ...

(BRITISH HERPETOL SOC, 2006-01)Insuetophrynus acarpicus is a poorly known frog restricted to the temperate forests of the coastal range of Chile (39 degrees 25' S, 73 degrees 10' W). Until recently, this species was known only from one type locality ...
-
(Blackwell, 2011)Aim The Chilean long-tailed snake (Philodryas chamissonis) has a wide distribution across different latitudes and ecosystems in Chile ranging from the south of the Atacama Desert (26 S) to the extremely humid Valdivian ...
-
(2004)The tobacco-feeding race of Myzus persicae (Sulzer), formerly known as M. nicotianae Blackman, was introduced into Chile during the last decade. In order to evaluate the genetic diversity and insecticide resistance status ...
-
(2012)The Chilotan Archipelago and surrounding areas of north-western Patagonia (41°–43°S, 72°–74°W) offer a unique opportunity to study the interplay between the recent genetic and paleoenvironmental evolution on temperate ...
-
(MDPI, 2022)Jubaea chilensis (Molina) Baill., also named Chilean palm, is an endemic species found in the coastal area of Mediterranean sclerophyllous forest in Chile. It has a highly restricted and fragmented distribution along the ...
-
(OXFORD UNIV PRESS, 2007-07)Background and Aims The endemic tree Nothofagus alessandrii (Fagaceae) has been historically restricted to the coastal range of Region VII of central Chile, and its forests have been increasingly destroyed and fragmented ...
-
(Springer, 2012)Colonising populations do not always exhibit founder effects. Common explanations are high levels of immigration and/or reproduction, but few empirical tests have been done. We measured genetic diversity of Nassauvia ...
-
(Elsevier, 2014)Although Phaseolus vulgaris L. is native from the Americas and is currently cultured in diverse areas, verylittle is known about the diversity of symbiotic nitrogen fixing Rhizobium (mycrosymbiont) in many ofthose cultures. ...
