Objective: To investigate the effect of nasal mucosa-derived ectodermal mesenchymal stem cells (NM-EMSCs) on the inflammatory state of rats with chronic rhinosinusitis (CRS) and the underlying therapeutic mechanism.
Methods: NM-EMSCs were isolated and extracted to construct a rat model of CRS. Fifteen Sprague‒Dawley (SD) rats were randomly divided into three groups: CK + NS group rats were injected locally with saline in the nasal mucosa; CRS + NS group rats were injected locally with saline in the nasal mucosa; and CRS + EMSCs group rats were injected locally with NM-EMSCs in the nasal mucosa.
Backgrounds: An understanding of the oncology nurse spiritual care competence would help nurse managers recognize weakness in spiritual practice and improve the quality of spiritual care. But the relationship between attitude towards death and spiritual care competence is unknown.
Methods: We recruited 326 nurses from hospitals in Guangzhou, China.
Many cell lines used for vaccine production have a potentially strong tumorigenic character. Some of those routinely used need to be checked at different passage numbers for this characteristic. Using HeLa cell cultures as positive controls, and primary canine kidney cell (CKC) or feline kidney cell (FKC) cultures purified in vitro on passage three as negative controls, the tumorigenicity of VERO cell sublines was tested in 219 nude mice.

Methods: The porcine alpha1, 3 galactosyltransferase gene siRNA targeted vector (pPNTloxPGTsiRNA) were construct with pPNTloxPGT and pMXSV/U6 vector. Positive-negative selection was used to produce a heterozygous pPNTloxPGTsiRNA knockout (+/-) clone.
