A modification of the newtonian dynamics as a possible alternative to the hidden mass hypothesis

open access: yes, 1983
The author considers the possibility that there is not, in fact, much hidden mass in galaxies and galaxy systems. If a certain modified version of the Newtonian dynamics is used to describe the motion of bodies in a gravitational field (of a galaxy, say),

Combining transient dynamics and logistic‐asymptotic growth to study the recovery of two seabird populations after rat eradication

open access: yesPopulation Ecology, EarlyView.
This study examines the demographic dynamics of two seabird populations on Tromelin Island, 15 years after the eradication of brown rats. The results indicate that these populations are in good health and are expected to continue growing until breeding sites are saturated in about a century.

Leveraging current insights on IL‐10‐producing dendritic cells for developing effective immunotherapeutic approaches

open access: yesFEBS Letters, EarlyView.
In vivo IL‐10 produced by tissue‐resident tolDC is involved in maintaining/inducing tolerance. Depending on the agent used for ex vivo tolDC generation, cells acquire common features but prime T cells towards anergy, FOXP3+ Tregs, or Tr1 cells according to the levels of IL‐10 produced. Ex vivo‐induced tolDC were administered to patients to re‐establish/
