By understanding the physiology behind voluntary and involuntary pitch fluctuation, an MU researcher expectations to find a treatment. ‘Hindustani and classical singing styles have become different,’ stated Nandhu Radhakrishnan, professor of conversation research and disorders in the School of Health Professions. ‘In Hindustani singing, performers use ‘Taan’ to modulate pitch voluntarily, while classical singers make use of vibrato to alter pitch involuntarily. With this knowledge, we may be able to create a specific therapy to cure laryngeal tremors.’ Radhakrishnan may be the first researcher to review the physiology of Hindustani singing. He worked with Ronald Scherer of Bowling Green State University in Ohio, and Santanu Bandyopadhyay, a vocal teacher in West Bengal, India.Images courtesy of PNAS/Giachi et. Al.. Clinical trial of gefitinib for advanced lung cancer closes early Researchers have closed a randomized clinical trial comparing gefitinib vs. Placebo following chemotherapy and radiation for individuals with non-small cell lung tumor that got spread and then nearby tissues or lymph nodes. Review of interim data indicated that gefitinib wouldn’t normally improve survival. The scientific trial was sponsored by the National Cancers Institute , and was executed by a network of experts led by the Southwest Oncology Group , Ann Arbor, Mich. AstraZeneca Pharmaceuticals LP, Wilmington, Del., which manufactures gefitinib, supplied the agent for the trial beneath the Clinical Trials Contract with NCI for the advancement of gefitinib.
