Q: They said a device that stimulates the vagus nerve in the neck while simultaneously playing different sounds for several weeks helped eliminate the condition in a group of rats. A trial of the treatment in humans is set to start in Europe this year, said Dr. Navzer Engineer of MicroTransponder, a medical device company affiliated with The University of Texas at Dallas, whose study appears in the journal Nature. Tinnitus is sometimes brought on by hearing loss. It occurs as cells in the inner ear are damaged, often from a loud noise. Current drugs help mask tinnitus, but the condition is incurable. Engineer’s team thinks tinnitus may be caused when too many brain cells become tuned to a specific tone in the brain. So his team set out to train the brain to ignore the nerve signals that cause the ringing sound. To do this, they paired a device that sends electrical impulses to the vagus nerve in the neck with different sounds. Stimulating this nerve releases chemicals such as acetylcholine and norepinephrine that trigger changes in the brain. The University of Texas at Dallas team tested this approach in a series of experiments with rats, using an indirect but accepted method of testing hearing in animals. In one, they stimulated the vagus nerve while playing different sounds 300 times a day for 20 days to a group of eight rats with a form of tinnitus. The tones were close to the frequency of the ringing sound, and the hope was to trick some of the nerve cells into listening to the new tones rather than the ringing tone. When the team checked the nerve responses to different tones, the tinnitus had disappeared in rats exposed to the tones and nerve stimulation, but it persisted in a group of control animals. “Unlike previous treatments, we’re not masking the tinnitus. We are eliminating the source of the tinnitus,” Michael Kilgard of the University of Texas-Dallas, who worked on the study, said in a statement. MicroTransponder is developing a wireless medical device to stimulate the vagus nerve and hopes to test it in people later this year. Cyberonics Inc already sells vagus nerve stimulation devices for people with epilepsy and depression. The National Institute on Deafness and Other Communication Disorders, part of the National Institutes of Health, funded a large part of the research.

Q: Bottles of Corona beer speed past a worker in the bottling line of Mexico City's Modelo brewery, May 19, 2004. REUTERS/Andrew Winning He may be in for worse than a surprise: a nasty skin reaction that one doctor is calling “Mexican beer dermatitis.”   A substance in lime juice, if left on the skin in the sun, can cause the skin to become discolored, as if by poison ivy or a jellyfish sting — and the marks can last for months, reports Scott Flugman in the Archives of Dermatology. Mexican beers, particularly Corona, are typically served with a lime slice wedged in the top of the bottle. The drinker shoves the lime into the bottle and holds his or her thumb over the bottle’s mouth while turning the bottle over to mix in the juice. But if the drinker is not careful, the beer’s carbonation can spray lime juice and beer all over his or her skin — “especially in a patient who is shirtless by a beach or pool,” wrote Flugman, a dermatologist in New York. The resulting reaction is due to a substance called psoralen, used to make the skin more sensitive to a wavelength of ultraviolet light, UV-A, used to treat certain skin conditions. Lemons contain psoralens too, but not as strong. “It’s just a cosmetic issue,” Flugman told Reuters Health, though he said the discoloration — most frequently in people like bartenders who work outdoors with limes — may take an emotional toll. “People are worried that it’s something serious. You might have some brown spots you’re been looking at for a few months,” he said. Olive-skinned Caucasians may be especially susceptible. No ties have been shown between the reaction and skin cancer, said Flugman, who added that he sees two or three cases a year. They are often mystified why a dermatologist is asking them if they’ve recently drunk Mexican beer. His advice? “If you do this and you spritz the beer or the lime, just wash it off. Don’t leave it on there and sit out in the sun,” he said. Or, if you are disinclined to get up for a while, “throw a towel over it.”

A: Hold the lime with Corona, may cause skin reaction.

Q: Virtually unknown just months ago, New York congressional candidate Alexandria Ocasio-Cortez arrived in Los Angeles as a rising political star, about a month after her improbable upset of 10-term U.S. Rep. Joe Crowley in a New York City Democratic primary. On Thursday, she intentionally avoided politicians and Hollywood celebrities, instead choosing to share the stage at the low-dollar fundraiser with activists pushing for broader rent-control laws in California and a public-backed banking system in the city. In her speech, she warned of a broken economy in which luxury apartments stand vacant while homeless crowd the streets, and talked of a Democratic Party in which the working class and marginalized are ascendant. Bursts of applause followed her calls for universal health care and a cost-free education through college. She swiped repeatedly, if indirectly, at President Donald Trump. “It is not us who are crazy, not with that man in the White House,” the former Bernie Sanders organizer said to cheers. Ocasio-Cortez was lauded by those who paid $27, or $10 for students, to see the candidate seen as the new face of the emerging democratic socialist movement. “She really inspires me, because she’s so young and she’s getting so far,” said Melainey Jane Foerster, 16, a high-school student from suburban Santa Clarita. Salesman Jon Pelzer, 65, said he’s “impressed by and energized by what she was able to do in New York.” “We share all the same values,” added Pelzer, a Democrat who ran on a similar platform in California’s 30th Congressional District but didn’t advance to November. The surprise victory by the political novice in a district that includes parts of the Bronx and Queens came after a low-budget campaign that she built around liberal and social causes, not the traditional Democratic Party machine. Crowley had been expected to win easily. Her platform includes expanding the Medicare program to people of all ages and abolishing Immigrations and Customs Enforcement. Her trip to California comes at a time when state and national Democrats have been contending with friction between their establishment and liberal wings. California Sen. Dianne Feinstein is being challenged in November by a fellow Democrat, state Sen. Kevin de Leon, who has positioned himself as a liberal alternative to the long-serving centrist. She warned of the influence of “coastal elites” in politics, and she recalled that her candidacy was largely dismissed. Ocasio-Cortez said she didn’t receive an endorsement from any incumbent “but we won anyway.” She urged the crowd to “engage in the fights that you know that are right.”
