Macrophage polarity and wound age determination. [PDF]

open access: yesSci Rep, 2022
We investigated the dynamics of the gene expression of M1 and M2 macrophage markers during skin wound healing in mice. Expression of M1-macrophage markers, such as Il12a, Tnf, Il6, Il1b, and Nos2 was upregulated after wounding and peaked at 1 or 3 days ...

A note on the preparation of sperm whale (Physeter macrocephalus) teeth for age determination

open access: yesJ. Cetacean Res. Manage., 2023
We describe a modification to the most common method of preparing sperm whale teeth for age determination. The first mandibular or nearest straightest tooth was sectioned in half with a slow-rotating band saw, polished and, rather than subjecting the ...

Aging steller sea lions by growth layer groups in teeth

open access: yesWildlife Society Bulletin, 2019
Accurate age determination of individuals is crucial in estimating age structure in populations as well as age‐specific rates of reproduction and survival. We examined growth layer groups (GLGs) in the canine, incisor, and postcanine teeth of Steller sea

Models for Pop I stars: implications for age determinations [PDF]

open access: yes, 2008
Starting from a few topical astrophysical questions which require the knowledge of the age of Pop I stars, we discuss the needed precision on the age in order to make progresses in these areas of research.

Mafic-ultramafic intrusions of Matokulma, Palojärvi, and Hongonniittu within the Central Finland Granitoid Complex with special reference to their petrogenesis and ore potential [PDF]

open access: yesBulletin of the Geological Society of Finland
We describe three previously unknown or poorly studied mafic-ultramafic intrusions (Matokulma, Palojärvi, Hongonniittu) from the south-central part of the Paleoproterozoic Central Finland Granitoid Complex (CFGC).

HEU age determination [PDF]

open access: yes, 1995
A new technique has been developed to determine the age of highly enriched uranium (HEU) in solids. Uranium age is defined as the time since the uranium-containing material was last subjected to a process capable of separating uranium from its radioactive-decay daughters.
