Using microstructures and composition to decipher the alterations of rodent teeth in modern regurgitation pellets—a good news-bad news story

open access: yes, 2020
Rodent accumulations are widely used for palaeoenvironmental reconstructions. But these accumulations are created through the activity of predators (carnivorous mammals, birds of prey), the predation and digestion of which modify the preservation of ...

Learning in the Rodent Motor Cortex.

open access: yesAnnual Review of Neuroscience, 2017
The motor cortex is far from a stable conduit for motor commands and instead undergoes significant changes during learning. An understanding of motor cortex plasticity has been advanced greatly using rodents as experimental animals.

Animal‐Free Setup of a 3D Mature Adipocyte‐Macrophage Co‐Culture to Induce Inflammation In Vitro

open access: yesAdvanced Healthcare Materials, EarlyView.
A completely animal‐free 3D co‐culture is developed using human fat cells and immune cells. Animal‐based materials are replaced with gellan gum hydrogel and a serum‐free medium. Immune cells are effectively activated, producing specific inflammatory signals.

At Home with Mastomys and Rattus: Human-Rodent Interactions and Potential for Primary Transmission of Lassa Virus in Domestic Spaces

open access: yesAmerican Journal of Tropical Medicine and Hygiene, 2017
The multimammate mouse (Mastomys natalensis) is the reservoir for Lassa virus (LASV). Zoonotic transmission occurs when humans are directly or indirectly exposed to fluids of the multimammate mouse, such as urine, saliva, and blood.
