The ontogeny of memory persistence and specificity

open access: yesDevelopmental Cognitive Neuroscience, 2019
Interest in the ontogeny of memory blossomed in the twentieth century following the initial observations that memories from infancy and early childhood are rapidly forgotten.

Organization of the Catecholaminergic System in the Short-Lived Fish Nothobranchius furzeri

open access: yesFrontiers in Neuroanatomy, 2021
The catecholaminergic system has received much attention based on its regulatory role in a wide range of brain functions and its relevance in aging and neurodegenerative diseases.

Age-related accumulation of B-1 cell progenitors in mice reflects changes in miR15a/16-1 expression and radioresistance capacity

open access: yesExperimental Hematology & Oncology, 2023
Hyperproliferative diseases such as Chronic Lymphocytic Leukemia (CLL) and Systemic Lupus Erythematosus (SLE) are potentially related to some disturbance in the apoptosis pathway, specifically in B-1a cells (CD5+).

The double burden of malnutrition and environmental enteric dysfunction as potential factors affecting gut-derived melatonin in children under adverse environments

open access: yesFrontiers in Nutrition, 2023
Graphical AbstractPoor environmental conditions combined with continuous unhealthy and unsafe diets may substantially increase the risk of a vicious cycle of enteric infections (EED–environmental enteric dysfunction) and malnutrition (DBM–double burden ...

Ontogeny, Phylotypic Periods, Paedomorphosis, and Ontogenetic Systematics

open access: yesFrontiers in Ecology and Evolution, 2022
The key terms linking ontogeny and evolution are briefly reviewed. It is shown that their application and usage in the modern biology are often inconsistent and incorrectly understood even within the “evo-devo” field.

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

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.

Abnormal Epigenetic Regulation of Immune System during Aging

open access: yesFrontiers in Immunology, 2018
Epigenetics refers to the study of mechanisms controlling the chromatin structure, which has fundamental role in the regulation of gene expression and genome stability.
