Angulations of mandibular third molar impaction and lower anterior crowding [PDF]

open access: yesIranian Journal of Orthodontics, 2007
Introduction: Despite a substantial body of literature refuting an association between third molar eruption and crowding of the lower anterior dentition, the issue continues to be controversial.

PiP‐Plex: A Particle‐in‐Particle System for Multiplexed Quantification of Proteins Secreted by Single Cells

open access: yesAdvanced Materials, EarlyView.
Detecting proteins secreted by a single cell while retaining its viability remains challenging. A particles‐in‐particle (PiPs) system made by co‐encapsulating barcoded microparticles (BMPs) with a single cell inside an alginate hydrogel particle is introduced.

When crowding of crowding leads to uncrowding

open access: yesJournal of Vision, 2013
In object recognition, features are thought to be processed in a hierarchical fashion from low-level analysis (edges and lines) to complex figural processing (shapes and objects). Here, we show that figural processing determines low-level processing. Vernier offset discrimination strongly deteriorated when we embedded a vernier in a square.

Emergent Motility of Self‐Organized Particle‐Giant Unilamellar Vesicle Assembly

open access: yesAdvanced Materials, EarlyView.
Giant unilamellar vesicles (GUVs), when combined with silica particles under alternating electric fields, spontaneously self‐assemble into motile structures. Asymmetric particle decoration induces fluid flows that propel the assemblies, enabling persistent motion and reversible control.

Colloidal Heterostructures Enable Interfacial Transport of Immiscible Molecules in Printable Organohydrogels

open access: yesAdvanced Materials, EarlyView.
Multiphase printable organohydrogels with tunable microstructures are developed to control molecular transport pathways for immiscible cargo. The tortuosity and domain size of the colloidal phases are tuned by adjusting temperature and shear during processing, which enables the tailoring of diffusion kinetics due to different transport pathways.

Volunteering and the State [PDF]

open access: yes
This paper explores the capability of the state to affect the individual's decision to work for free. For this purpose we combine individual-level data from the European and World Values Survey with macroeconomic and political variables for OECD member ...

Mixing and segregation of ring polymers: spatial confinement and molecular crowding effects

open access: yesNew Journal of Physics, 2014
During the life cycle of bacterial cells the non-mixing of the two ring-shaped daughter genomes is an important prerequisite for the cell division process.

High‐Throughput In Vivo Screening Using Barcoded mRNA Identifies Lipid Nanoparticles With Extrahepatic Tropism for In Situ Immunoengineering

open access: yesAdvanced Materials, EarlyView.
A high‐throughput in vivo mRNA LNP screening platform is developed and employed to screen a large library of 122 mRNA LNPs in vivo for delivery to immune, stromal, and parenchymal cells, identifying promising LNP candidates. A novel small particle flow cytometry‐based protein adsorption analysis method is utilized to interrogate protein corona ...

Pattern of malocclusion in patients with noma sequelae: The need for orthodontic and orthognathic therapy

open access: yesSaudi Journal of Oral Sciences
Introduction: Noma is a gangrenous infection that destroys the orofacial structures and leaves the survivors with severe functional, psychosocial, and esthetic impairments. Malocclusion is one of the central sequelae that current Noma care often neglects.

Experimental evidence for density-determined wing dimorphism in two bush-crickets (Ensifera: Tettigoniidae)

open access: yesEuropean Journal of Entomology, 2009
Macroptery is common in many species of Orthoptera, but the causes are still discussed. Besides the assumption that macroptery is genetically determined, there is evidence that wing dimorphism is induced by environmental factors, particularly population ...
