Surface manipulation for prevention of migratory viscous crude oil fouling in superhydrophilic membranes

open access: yesNature Communications, 2023
Here, we present a proactive fouling prevention mechanism that endows superhydrophilic membranes with antifouling capability against migratory viscous crude oil fouling. By simulating the hierarchical architecture/chemical composition of a dahlia leaf, a

The conditioning of social networking sites in the formation of migratory chains of unaccompanied foreign minors

open access: yesMedia Education, 2022
The relational uprooting faced by young unaccompanied minors, when they undertake a migratory process, it places them in a situation of extreme vulnerability. Timeshare in the Center for Minors offered relationships between themselves, which are later maintained and reflected on social networking sites.

Retinoic acid upregulates ret and induces chain migration and population expansion in vagal neural crest cells to colonise the embryonic gut.

open access: yesPLoS ONE, 2013
Vagal neural crest cells (VNCCs) arise in the hindbrain, and at (avian) embryonic day (E) 1.5 commence migration through paraxial tissues to reach the foregut as chains of cells 1-2 days later.

The magnetite-based receptors in the beak of birds and their role in avian navigation [PDF]

open access: yes, 2012
Iron-rich structures have been described in the beak of homing pigeons, chickens and several species of migratory birds and interpreted as magnetoreceptors.

Homeostatic Interactions at the Front of Migration Control the Integrity and the Efficiency of a Migratory Glial Chain [PDF]

open access: yesThe Journal of Neuroscience, 2011
In metazoans, cell migration often occurs in a collective manner: the cells move while physically and functionally connected to their neighbors. The coordinated and timely movement of the cells eventually ensures the proper organization of tissues, and deregulation in such a process contributes to the development of severe diseases. Thus, understanding

Pigmented melanoma cell migration study on murine syngeneic B16F10 melanoma cells or tissue transplantation models [PDF]

open access: yes, 2019
Melanoma is a lethal form of skin cancer with poor prognosis, especially due to the early metastatic feature. Recent studies have shown that the melanin pigment influences the nanomechanical properties and, therefore, the metastatic behavior of the ...

L’impossible gouvernement de la migration? Gestions locales d’espèces globales : les migrateurs amphihalins (anguille européenne et saumon atlantique)

open access: yesVertigO, 2021
This article looks at the governance of two highly migratory fish species: European eel (Anguilla anguilla) and Atlantic salmon (Salmo salar). Based on a long ethnographic field survey, this paper proposes to analyse the modalities of fisheries and stock

Girdin Is an Intrinsic Regulator of Neuroblast Chain Migration in the Rostral Migratory Stream of the Postnatal Brain [PDF]

open access: yesThe Journal of Neuroscience, 2011
In postnatally developing and adult brains, interneurons of the olfactory bulb (OB) are continuously generated at the subventricular zone of the forebrain. The newborn neuroblasts migrate tangentially to the OB through a well defined pathway, the rostral migratory stream (RMS), where the neuroblasts undergo collective migration termed “chain migration.”
