Adding more beef silver skin makes cooked meat products softer and less chewy, with hardness dropping from 36.9 to 32.9 units, gumminess from 8.78 to 7.70, and chewiness from 27.9 to 22.1 as silver skin increases from 0% to 10%.
Correlational
As more beef silver skin is added to meat mixtures, the cooked product becomes darker, with lightness dropping from 64.1 to 62.9 when silver skin goes from 0% to 10%.
Adding more beef silver skin to meat mixtures causes more fat to leak out during cooking, going from about 1.4% to 2.3% as the silver skin amount goes from 0% to 10%.
Rats given the peptides healed their skin wounds about a day or two faster than those not given the peptides.
Higher doses of the peptides led to stronger skin and uterine wounds, with the highest dose showing the best results.
At one week, the peptides increased CD31, a marker for blood vessels, helping to form new vessels in the wound area.
Within the first two weeks, the peptides boosted levels of bFGF, a growth factor that helps skin cells multiply and repair the wound.
The peptides increased levels of a growth factor (TGF-β1) in the skin wounds after two weeks, which helps in tissue repair and collagen production.
After two weeks, the skin wounds of rats given the peptides had more collagen, which is the main structural protein needed for strong healing.
The peptides helped form more blood vessels in the skin wounds of rats within a week, which is important for delivering nutrients to heal the wound.
Rats given the peptides had more hydroxyproline in their skin wounds, which is a key component of collagen and helps in tissue repair.
Rats given salmon collagen peptides after C-section had stronger uterine tissue that could withstand more pressure, reducing the risk of rupture during future pregnancies.
Rats given a specific dose of salmon collagen peptides after C-section surgery healed faster with stronger skin wounds compared to rats not given the peptides.
Rats with PCOS received L-arginine at 3.5 mg per kilogram daily for three weeks.
Descriptive
Rats with PCOS were given licorice extract at a dose of 150 mg per kilogram for three weeks.
Scientists caused PCOS in rats by giving them a specific dose of letrozole for three weeks.
After damaging the eye tissue with enzymes, the special peptide reduced broken collagen levels compared to a saline solution, as seen with a fluorescent marker.
When rats' eye tissues were treated with collagen-breaking enzymes, there was more broken collagen detected by a special fluorescent marker compared to normal tissue.
After damaging the inner optic nerve head tissue with enzymes, adding saline solution slightly increased stiffness by about 13% compared to the damaged state.
Quantitative
After damaging the inner optic nerve head tissue with enzymes, the special peptide restored stiffness by nearly 50% compared to the damaged state.
In the inner part of the eye's optic nerve head, collagen-breaking enzymes caused a 57% drop in stiffness compared to normal.
After damaging the eye tissue with enzymes, adding a saline solution (vehicle) made the stiffness drop even more by about 26% compared to the damaged state.
After damaging the eye tissue with collagen-breaking enzymes, applying a special peptide helped restore some stiffness, increasing it by about 23% compared to the damaged state.
When rats' eye tissue was treated with an enzyme that breaks down collagen, the stiffness of the outer part of the eye decreased by almost 40% compared to normal.
