Intertissue mechanical stress affects frizzled-mediated planar cell polarity in the drosophila notum epidermis
Frizzled/planar cell polarity (Fz/PCP) signaling controls the orientation of sensory bristles and cellular hairs (trichomes) along the anteroposterior axis of the Drosophila thorax (notum) [1-4]. A subset of the ...
Dynamics and orientation of parathion dissolved in a discotic nematic lyomesophase
(CSIRO Publishing, 2008)
Parathion, an organophosphorous pesticide, presents serious hazards to the environment and health. It inhibits acetylcholinesterase, an enzyme incorporated in the cell membrane. A study on the behaviour of parathion in a ...
Location, orientation and dynamics of two molecules with mitochondrial activity dissolved in anionic lyomesophase. A 2H-NMR and MD study
(Sociedad Chilena de Quimica, 2012)
4,4-Dimethyl-5,8-dihydroanthracene-1,9,10(4H)-trione (Q1) and 9,10-Dihydroxy-4,4-dimethyl-5,8-dihydro-1 (4H)-anthracenone (Q2), two molecules that inhibit cancer cell respiration, were selectively deuterated and dissolved ...
Jitterbug/Filamin and Myosin-II form a complex in tendon cells required to maintain epithelial shape and polarity during musculoskeletal system development
(Elsevier Ireland Ltd, 2018)
© 2018 Elsevier B.V. During musculoskeletal system development, mechanical tension is generated between muscles and tendon-cells. This tension is required for muscle differentiation and is counterbalanced by tendon-cells ...
Microtubule configuration and its relationship to sperm morphology in mammalian spermiogenesis
The acrosome is a secretory vesicle located in the mammalian sperm head. Its main function is to transport hydrolytic enzymes. These enzymes will dissolve the zona pellucid, assisting the sperm in fertilizing the egg. The ...
Amino β-cyclodextrins immobilized on gold surfaces: Effect of substituents on host-guest interactions
(Elsevier Ltd, 2018)
In the present paper we describe a simple method to immobilize amino cyclodextrins (CDs) and methylated-amino cyclodextrins on gold surfaces. We also report on the effect that the presence of methyl groups in the broader ...
Expression and behaviour of CENP-E at kinetochores during mouse spermatogenesis
Centromere protein E (CENP-E) is a microtubule motor protein localised in the outer kinetochore plate and in the fibrous corona that relocalises to the midzone in early anaphase. While its expression in somatic cells has ...
Label-Free Graphene Oxide-Based Surface Plasmon Resonance Immunosensor for the Quantification of Galectin-3, a Novel Cardiac Biomarker
(American Chemical Society, 2018)
© 2018 American Chemical Society. We report the first optical biosensor for the novel and important cardiac biomarker, galectin-3 (Gal3), using the anti-Gal3 antibody as a biorecognition element and surface plasmon resonance ...
Magmatic platinum nanoparticles in metasomatic silicate glasses and sulfides from Patagonian mantle xenoliths
(Springer Verlag, 2019)
Platinum-rich nanonuggets (s.l., nanoparticles) are commonly produced in experiments attempting to quantify the solubility or partitioning of noble metals in silicate and sulfide melts. However, it has been thought that ...
