Results of a study in non-human primates, published in Nature Communications, suggest that Zika virus is not transmitted through casual contact with saliva, such as by kissing or sharing eating utensils. "If passing the virus by casual contact were easy, I think we would see a lot more of what we would call secondary transmission in a place like the United States," said lead researcher Tom Friedrich, from the University of Wisconsin's School of Veterinary Medicine.
Rowan Nickerson of Wenatchee, Wash., was 7 months old when she died from sudden infant death syndrome, and her parents, Olivia and Josh, chose to donate her tissue and heart valves through LifeNet Health Northwest. Olivia Nickerson said she did not expect to be asked about donation but is glad she was.
Thermo Fisher Scientific obtained FDA emergency use authorization for its TaqPath Zika Virus Kit for use in qualitative detection of Zika virus RNA and diagnosis of Zika infection using human serum and urine. The QuantStudio Dx Real-Time PCR system and the King Fisher Flex system for automated sample extraction make up the complete testing workflow, the company said.
A new mouse model with suppressed interferon response has yielded clues about prenatal and sexual routes of Zika virus transmission, NIH researchers wrote in Scientific Reports. Only some fetuses acquired Zika from infected mothers, suggesting the placenta can be an important barrier, and the team also found Zika persists in the testes, contributing to sexual transmission.
A study in the journal Respiratory Research found that lung spheroid stem cells could be collected via transbronchial biopsy, cultured and infused into mice without triggering an adverse immune reaction. Researchers from the University of North Carolina School of Medicine and North Carolina State University are preparing a clinical trial of the technique for the treatment of idiopathic pulmonary fibrosis.
Ohio State University scientists are investigating a wound-healing method in which a small computer chip placed on the wound site delivers programmed DNA or RNA cells into living skin cells through an electrical field. The tissue nanotransfection technique is expected to be in human trials by next year and may have potential against peripheral vascular disease.
A technology called tissue nanotransfection uses nanochips to reprogram skin cells in a damaged area, allowing regeneration of any kind of cell needed for medical treatment, even precursors for vascular tissue or organs. An Ohio State University team that tested the technology in pigs and mice reported a 98% success rate, and human trials are expected next year.
Breast cancer patients who want reconstructive surgery following a lumpectomy or mastectomy generally can choose implants or have it done with their own tissue, said plastic surgeon Babak Mehrara of Memorial Sloan Kettering Cancer Center. Implants are more popular, Mehrara said, but the advantage of autologous reconstruction is that it uses a patient's own tissue, which is natural and changes if the patient gains or loses weight.
The 2017 AATB Annual Meeting will provide attendees with education opportunities associated with many of the tissue banking technologies and innovations that continually improve tissue banking processes. Concurrent sessions will offer professionals working in areas related to donor screening, tissue recovery, tissue processing and distribution, regulatory and reproductive tissues, many opportunities to share new ideas to further improve their tissue banking operations. Review the agenda and register today for the 2017 AATB Annual Meeting -- Oct. 3-6 Renaissance Orlando at SeaWorld, Florida!
