objective: it is hypothesized that stem cells have the capability to form tumors after transplantation. spermatogonial stem cells have proliferation potency and colonization ability related to express pluripotency genes such as c-myc. the primary aim of this study is to investigate tumorigenicity ability of these cells after in vitro cultivation and inoculation in athymic animals. methods: sper...

In the wake of COVID-19 pandemic, there is an urgent need to inoculate as many people possible achieve herd immunity (Mayo Clinic, 2021). Information campaigns have become crucial incr...

Subgingival plaque samples obtained from human subjects with periodontitis, shown to include previously uncultivable members of the phylum Synergistetes, were used to inoculate Cooked Meat Medium (CMM). The presence of Cluster A (uncultivable) Synergistetes was monitored by fluorescent in situ hybridization (FISH) and quantitative PCR (Q-PCR). Cluster A Synergistetes were found to grow in CMM i...

Cycloserine-cefoxitin-fructose agar (CCFA) and cycloserine-cefoxitin-fructose broth (CCFB) containing either 500 or 250 micrograms of cycloserine per ml were compared for efficacy in the isolation of Clostridium difficile from hospital ward environmental sites. A RODAC imprint technique was used to inoculate prereduced CCFA. Moistened swabs were used to inoculate prereduced CCFB from environmen...
