ApoE Mimetic Peptides to Improve the Vicious Cycle of Malnutrition and Enteric Infections by Targeting the Intestinal and Blood-Brain Barriers

open access: yesPharmaceutics, 2023
Apolipoprotein E (apoE) mimetic peptides are engineered fragments of the native apoE protein’s LDL-receptor binding site that improve the outcomes following a brain injury and intestinal inflammation in a variety of models.

Ontogenetic shape trajectory of Trichomycterus areolatus varies in response to water velocity environment.

open access: yesPLoS ONE, 2021
Body and head shape among fishes both vary between environments influenced by water velocity and across ontogeny. Although the shape changes associated with variation in average water velocity and ontogeny are well documented, few studies have tested for

Swimming abilities of temperate pelagic fish larvae prove that they may control their dispersion in coastal areas [PDF]

open access: yes, 2019
The Sense Acuity and Behavioral (SAAB) Hypothesis proposes that the swimming capabilities and sensorial acuity of temperate fish larvae allows them to find and swim towards coastal nursery areas, which are crucial for their recruitment. To gather further

Ontogeny of neuroembryology [PDF]

open access: yesThe Journal of Neuroscience, 1988
This essay commemorates the 100th anniversary of the birth of neuroembryology. One cannot, of course, ascribe the beginning of a branch of science to a single year, but the years between 1885 and 1890 saw major publications by the German anatomist Wilhelm His (1831–1904) and the Spanish histologist S.

Toward a physiological explanation of juvenile growth curves [PDF]

open access: yes, 2020
Juvenile growth curves are generally sigmoid in shape: Growth is initially nearly exponential, but it slows to near zero as the animal approaches maturity.

Loneliness Across the Life Span [PDF]

open access: yes, 2015
Most people have experienced loneliness and have been able to overcome it to reconnect with other people. In the current review, we provide a life-span perspective on one component of the evolutionary theory of loneliness—a component we refer to as the ...

On growth and form of irregular coiled-shell of a terrestrial snail: Plectostoma concinnum (Fulton, 1901) (Mollusca: Caenogastropoda: Diplommatinidae) [PDF]

open access: yesPeerJ, 2014
The molluscan shell can be viewed as a petrified representation of the organism’s ontogeny and thus can be used as a record of changes in form during growth.
