Animals insight five zinc isotopes. Medical search. Frequent questions

Nitrogen isotope analysis, in particular, can help scientists learn if past humans were eating animals or plants. (sciencedaily.com)
The protein collagen found in bone and teeth, which is required for these analyzes, is difficult to preserve long-term, so traditional nitrogen isotope analysis is often not possible," McCormack says. (thewestonforum.com)
While nitrogen isotope analysis has shed light on some other Neanderthal remains, it wouldn't work on the Gabasa tooth, so researchers instead tested zinc isotope ratios in the enamel. (sciencealert.com)

In this study, researchers analysed the zinc stable isotope ratios from animal and human teeth from two sites in the Huà Pan Province of Laos: Tam Pà Ling and the nearby site of Nam Lot. (sciencedaily.com)
With zinc stable isotope ratios, we can now study Tam Pà Ling and learn what kind of food our earliest ancestors in this region were eating. (sciencedaily.com)
In this way, the researchers were also able to determine the zinc isotope ratios of megalodon teeth from the early Pliocene (5.3 to 3.6 million years ago) and of great white sharks living then and now in order to get indications about the interactions that might occur there. (thewestonforum.com)
Traditionally, scientists hoping to figure out an extinct animal's position in the food web must extract proteins and analyze nitrogen isotopes from bone collagen - higher ratios of nitrogen-15 compared to nitrogen-14 is indicative of greater amounts of meat consumption . (sciencealert.com)

An international team of scientists has now applied a new method to investigate the diet of fossil humans: the analysis of stable zinc isotopes from tooth enamel. (sciencedaily.com)
Another kind of analysis performed in this study -- stable carbon isotopes analysis -- indicates that the food consumed came strictly from forested environments," says Élise Dufour, researcher at the National Natural History Museum of Paris. (sciencedaily.com)

For example, only 90 atoms of Flerovium - the 114th element, first discovered in 1999 - have ever been observed, with its most stable isotope (variant) only having a half-life (the time it takes for half of it to decay) of around 1.9 seconds. (expressdigest.com)

An international team of researchers has now gained insight into this question using a new detection method. (thewestonforum.com)
As part of their study, the researchers have now discovered to what extent zinc isotope fingerprints allow conclusions to be drawn about the sharks' diet. (thewestonforum.com)
Led by Klervia Jaouen from the French National Centre for Scientific Research (CNRS), the researchers conducted the zinc isotope analysis on the Neanderthal molar as well as bones from several contemporary animal species found nearby, including herbivores and carnivores. (sciencealert.com)
Lower proportions of zinc-66 isotopes in an animal's bones tend to correspond with a higher likelihood that animal was a carnivore, the researchers explain. (sciencealert.com)
Many contemporary carnivores in this region likely consumed the bones and blood of their prey, which could have raised their zinc isotope signature, the researchers note. (sciencealert.com)
This type of zinc isotope analysis makes it easier to identify animals as carnivores or omnivores, the researchers say, and it could soon help resolve that question for Neanderthals more broadly. (sciencealert.com)

This ancient molar has yielded new insights on the diet of a Neanderthal. (sciencealert.com)
And based on the low zinc isotope signature found in this Neanderthal molar, Jaouen and her colleagues conclude it probably came from a dedicated meat eater. (sciencealert.com)

Because it now represents an important addition to the nitrogen isotope analyzes of dental collagen, which previously provided conclusions about diets. (thewestonforum.com)

New methods -- such as zinc isotope analysis of enamel -- can now overcome these limitations and allow us to investigate teeth from regions and periods we could not study before," says study leader Thomas Tütken, professor at the Johannes Gutenberg University's Institute of Geosciences. (sciencedaily.com)
For the first time, we were able to extract Conclusions about the diet of these animals based on zinc isotope fingerprints in the highly mineralized enamel crown of fossil shark teeth. (thewestonforum.com)
This method takes advantage of changes in the concentration of zinc in enamel with each step in a food chain, a feature demonstrated in modern remains and a few ancient animal bones. (sciencealert.com)

The cryo-EM structure of the trapped RNF213:E2∼Ub intermediate reveals RNF213 C-terminal domain as the E2 docking site, which positions the ubiquitin-loaded E2 proximal to the catalytic zinc finger, facilitating nucleophilic attack of Cys4462 on the E2∼Ub thioester. (biorxiv.org)

Zinc homeostasis is tightly controlled by a series of transporter proteins that are broadly categorized into two major families, the Slc39a or Zip family and the Slc30a or ZnT family. (biomedcentral.com)
Generally speaking, Zip proteins function in transporting zinc into the cytoplasm from extra- or intracellular vesicles, while ZnT proteins transport zinc in opposite orientations to efflux zinc out of the cytosol [ 15 , 16 ]. (biomedcentral.com)

Collectively, our results provide new insights into the immunomodulatory mechanism of ASFV CD2v. (bvsalud.org)

Borne by high winds, strontium-90 had not only contaminated vegetables across the country, it had also contaminated the nation's meat and milk supply (meat and milk of animals who had consumed contaminated hay and grass tended to have high levels of strontium-90 which could be passed on to those who consumed these foods). (positivehealth.com)

It will be interesting, in the future, to compare our zinc isotope data with data from other prehistoric human species of Southeast Asia, like Homo erectus and Homo floresiensis , and see if we could understand better why they went extinct while our species survived," concludes first author Nicolas Bourgon, a researcher at the Max Planck Institute for Evolutionary Anthropology. (sciencedaily.com)
Zinc isotope signals are coherent in fossils and corresponding modern species. (thewestonforum.com)

Biochemical and activity-based probe analyses identify a non-canonical zinc finger domain as the E3 active site, which utilizes the strictly conserved Cys4462, not involved in zinc coordination, as the reactive nucleophile. (biorxiv.org)

A radioactive isotope produced by nuclear fission, strontium-90 had an "affinity for bone" and scientists in the 1950s and 1960s feared that it could cause cancer. (positivehealth.com)
Because this Neanderthal has such a low zinc isotope signature, Jaouen and her colleagues suspect the individual ate a lot of animal meat, but not the blood or bones (possibly aside from bone marrow). (sciencealert.com)

Preliminary results show that zinc measurement in protein (fingernails) is a better indicator for zinc status than zinc measurements in plasma. (usda.gov)
Our results indicate that Zip71B/dZip5 is involved in zinc import into the tubular cells from the circulation, and ZnT35C in turn effluxes the tubular zinc out. (biomedcentral.com)
