From samples of wild and captive zebras, viral DNA was extracted from blood samples and nasal swabs using a commercially available kit (NucleoSpin Tissue, Macherey-Nagel, Dren, Germany) according to the manufacturers instructions for the respective sample type (blood or buccal swab protocol, respectively)
But make no mistake, the landscape changed today
Specifically, GHK-Cu was found to be least possible to cause skin irritation, while CuCl 2 and Cu(OAc) 2 were found to induce the expression of various skin irritation biomarkers, i.e., IL-1, IL-8, FOSL1, and HSPA1A
The following phenomena were observed based on TEM analysis in group B: a large number of vacuoles in the cytoplasm, obvious oedema and cavitation of organelles, increased levels of abnormal lipids, rupture of the nuclear membrane of interstitial cells, mitochondrial oedema, partial absence of cytoplasm, increased nuclear heterochromatin, expansion of endoplasmic reticulum, obvious damage to the spermatogonia membrane, a few vacuoles near the membrane, endoplasm of primary spermatocytes, insignificant swelling of the endoplasmic reticulum, the lack of a defined cell membrane, increased nuclear heterochromatin and the formation of large vacuoles next to secondary spermatocytes
