(Mary Ann Liebert, 2015)
-
(2007)Template-directed synthesis is a promising route to realize vanadate-based 1-D nanostructures, an example of which is the formation of vanadium pentoxide nanotubes and associated nanostructures. In this work, we report the ...
-
(1983)2,4‐Dihydroxy‐7‐methoxy‐1,4‐benzoxazin‐3‐one (DIMBOA), the main hydroxamic acid isolated from maize extracts, increased the mortality of Schizaphis graminum when fed in artificial diets. Electrically‐monitored feeding ...
-
(1990)SUMMARY. A soluble cell fraction lethal to Daphnia magna was isolated by the disruption of net phytoplankton from eutrophic Aculeo Lake. The phytoplankton of this lake is dominated by Microcystis sp. The soluble fraction ...
-
Tracer diffusion and activity coefficients of counterions in aqueous solutions of polyelectrolytes (1969)Tracer diffusion coefficients of Ag+ in silver polystyrenesulfonate and counterion activity coefficients of sodium and silver polystyrenesulfonates have been determined at different concentrations. The results have been ...
-
(GAUTHIER-VILLARS/EDITIONS ELSEVIER, 2006-05)Nectar thieves may increase or decrease pollinator-mediated pollen flow and thus may have positive or negative effects on plant reproductive success. In temperate rainforests of South America, the hummingbird Sephanoides ...
-
(Elsevier, 2018-05-15)Elucidating the timing and regional extent of abrupt climate events during the last glacial-interglacial transition (similar to 18-11.5 ka) is critical for identifying spatial patterns and mechanisms responsible for ...
-
(Elsevier, 2022)Carbon-based materials are the promising candidates for the design of multifunctional spintronic devices, owing to their fascinating inherent attributes such as the ballistic transport nature, long spin coherence time, ...
-
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2003-09-35)The genes that control development of embryonic melanocytes are poorly defined. Although transcription factor Ap-2a is expressed in neural crest (NC) cells, its role in development of embryonic melanocytes and other neural ...
-
(AMER SOC MICROBIOLOGY, 2009-07-30)The acidophilic Acidithiobacillus ferrooxidans can resist exceptionally high copper (Cu) concentrations. This property is important for its use in biomining processes, where Cu and other metal levels range usually between 15 ...
-
(2014)Growing evidence suggests that the main olfactory epithelium contains a subset of olfactory sensory neurons (OSNs) responding to pheromones. One candidate subpopulation expresses the calcium activated cation channel TRPM5 ...

-
(1995)Yeast artificial chromosomes (YACs) from the CEPH MegaYAC library (Paris, France) ranging in size from 350 to 1600 kb and mapping to the q22.1 and q22.2 regions of human chromosome 21 were transferred into mammalian cells ...
-
(1999)The cellular mechanism by which basolateral transferrin (Tf) produces an increase in apical-to-basolateral Fe flux in Caco-2 cells was analyzed. After a pulse of 59Fe from the apical medium, three types of basolateral 59Fe ...
-
(ELSEVIER SCIENCE INC, 2009-07)CD4 CD25 Foxp3 regulatory T cells (Treg) mediate immunologic self-tolerance and suppress immune responses. In the gut, a subset of dendritic cells is specialized to induce Treg in a transforming growth factor- (TGF- ...
-
(IRCA-BSSA, 2017)Fibroblasts play several homeostatic roles, including electrical coupling, paracrine signaling and tissue repair after injury. Fibroblasts have low secretory activity. However, in response to injury, they differentiate to ...
-
(American Society Microbiology, 2017)The dynamic response of organisms exposed to environmental pathogens determines their survival or demise, and the outcome of this interaction depends on the host's susceptibility and pathogen-dependent virulence factors. ...
-
(Elsevier Ltd, 1998)We discuss the recent appearance of very broad (FWZI∼20000 km s-1) double-peaked Balmer emission lines in the nuclei of the galaxies NGC 1097, Pictor A and M 81. Such profiles are rare, and only found in about 10% of ...
