But the clinical effectiveness of these stem cells has only been modest, which may be due to the advanced age of the patients or the effects of chronic diseases such as diabetes and cardiovascular disease, according to a probing Review article published in BioResearch Open Access, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers . The article is available on the BioResearch Open Access website. Anastasia Yu. Efimenko, TN Kochegura, ZA Akopyan, and YV Parfyonova, Moscow State University (Russia), analyze how aging and chronic diseases might affect the regenerative potential of autologous stem cells and explain the differences between the promising results reported in preclinical studies using stem cells derived from … Continue reading →

Scientists from Oregon State University in the US have developed a means to selectively introduce compounds into cancer cells so that they can be identified and malignant tissues removed in combination with phototherapy, and also killing remaining cancer cells once a tumor has been removed, preventing recurrence. Based on successful laboratory trials, this mix of surgery and non-toxic phototherapy has great potential for improving on existing chemotherapies and radiotherapies. Although for many cancers surgery is the first choice treatment, it is not easy to remove most of the tumors, and residual cancer cells can eventually lead to relapse. The team were therefore exploring novel nanotechnology-based platforms to treat different cancers using intraoperative guidance with a real-time near infrared (NIR) fluorescence signal. As reported in the journal Nanoscale [Taratula et al. Nanoscale (2015) DOI: 10.1039/C4NR06050D], they devised a system for greater accuracy in the surgical removal of solid tumors and eradicating remaining cancer cells using the compound naphthalocyanine. This derivative of phthalocyanine has unusual properties when exposed to near-infrared light, such as making cells glow thus helping to guide surgeons to specific cells and heating the cell to kill it off through mild heating and the development of reactive oxygen species. … Continue reading →
