An ontogeny-cytokine code determines macrophage response polarity and tumor outcomes [PDF]

open access: yesCommunications Biology
Tumor-associated macrophages can either promote or suppress cancer, but therapeutic targeting remains challenging because we lack a predictive framework for macrophage function.

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.

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 ...

New skulls of the basal sauropodomorph Plateosaurus trossingensis from Frick, Switzerland: Is there more than one species? [PDF]

open access: yesActa Palaeontologica Polonica, 2021
The Triassic basal sauropodomorph Plateosaurus trossingensis is well-known from mass accumulations at the German localities of Trossingen and Halberstadt and the Swiss locality of Frick, and is significant especially regarding its taphonomy and proposed ...

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
