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.

Pterodactylus scolopaciceps Meyer, 1860 (Pterosauria, Pterodactyloidea) from the Upper Jurassic of Bavaria, Germany:the problem of Cryptic Pterosaur Taxa in early ontogeny [PDF]

open access: yes, 2014
The taxonomy of the Late Jurassic pterodactyloid pterosaur Pterodactylus scolopaciceps Meyer, 1860 from the Solnhofen Limestone Formation of Bavaria, Germany is reviewed. Its nomenclatural history is long and complex, having been synonymised with both P.

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

Rethinking the ontogeny of mindreading [PDF]

open access: yes, 2006
We propose a mentalistic and nativist view of human early mental and social life and of the ontogeny of mindreading. We define the mental state of sharedness as the primitive, one-sided capability to take one's own mental states as mutually known to an ...
