These Lab-Grown Vocal Cords Sound Like The Real Thing

A team of scientists at the University of Wisconsin-Madison has bioengineered vocal cord tissue capable of vibrating and generating sound as well as natural tissue. The feat is being hailed as a scientific first. The lab-grown tissue may one day be used to restore the voices of patients with damaged vocal cords or those who may have lost theirs to cancer surgery or injuries, according to a study published in the journal Science Translational Medicine on Wednesday. "I was surprised and even shocked at how well the tissue performed," Dr. Nathan Welham, a speech-language pathologist at the university and lead author of the study, told The Huffington Post. "You always engage in research because you hope for the best, but I certainly didn't expect that the function would be as exquisite and comparable to the natural vocal fold function." The researchers collected cells that make up human vocal cord tissue, and then purified and grew the cells before arranging them on a 3D collagen scaffolding structure.  Over two weeks, the cells continued to grow on the structure. They formed the shape of human vocal cords, taking on the viscosity and elasticity of healthy vocal cord tissue. "When we first made these tissues, I was struck by how they felt like regular vocal fold tissue," Welham said. "It was at that point when I first felt the tissue that I realized, gosh, this really seems like the real thing and that we should do some more testi...

Excerpted fromPrecision Medicine and the Reinvention of Human DiseaseDespite having the most advanced healthcare technology on the planet, life expectancy in the United States is not particularly high. Citizens from most of the European countries and the highly industrialized Asian countries enjoy longer life expectancies than the United States. According to the World Health Organization, the United States ranks 31st among nations, trailing behind Greece, Chile, and Costa Rica, and barely edging out Cuba [42]. Similar rankings are reported by the US Central Intelligence Agency [43]. These findings lead us to infer that acc...

By Stacy Simon The death rate from cancer in the US has declined steadily over the past 2 decades, according to annual statistics reporting from the American Cancer Society. The cancer death rate for men and women combined fell 25% from its peak in 1991 to 2014, the most recent year for which data are available. This decline translates to more than 2.1 million deaths averted during this time period. “Cancer Statistics, 2017,” published in the American Cancer Society’s journal CA: A Cancer Journal for Clinicians, estimates the numbers of new cancer cases and deaths expected in the US this year. The estimat...

By Stacy Simon The American Cancer Society has released a new Head and Neck Survivorship Care Guideline to help survivors of head and neck cancer and their primary care providers better manage their long-term care. The guideline addresses cancers of the oral cavity, tongue, lip, pharynx (throat), and larynx (voice box). Recommendations in the guideline may also apply to cancers of the salivary glands, nasal and paranasal sinuses, and nasopharynx. But it does not address cancers of the brain, thyroid, or esophagus because they are very different in terms of symptoms and treatment. RESOURCES: Head and Neck Cancer Survivor...

Abstract OBJECTIVE: Conflicting results on the association between fruit consumption and cancer risk have been reported. Little is known about the cancer preventive effects of different fruit types. The present meta-analysis investigates whether an association exists between apple intake and cancer risk. DESIGN: Relevant observational studies were identified by literature search (PubMed, Web of Science and Embase). A random-effect model was used to estimate the cancer risk in different anatomical sites. Between-study heterogeneity and publication bias were assessed using adequate statistical tests. RESUL...

January is Cervical Cancer Month. So it is time to look at what has been accomplished recently in control of this disease. Getting treatment for advanced cervical cancer is challenging. Patients often have pelvic pain, sometimes with blockage of intestines and the urinary tract. Regrettably many patients have fistulas (holes) develop where they leak urine or stool through the skin, vagina or bladder. These are cruel consequences of failed cancer control. About 13,000 women will develop cervical cancer every year, and tragically 4,000 will die of the illness. In 2014, the FDA approved a new treatment for advanced cervical...
