SEATTLE — Steve Goforth’s wait is over. On Sunday afternoon, the 37-year-old Everett firefighter and paramedic got the page he had been waiting months to hear. Click here to read more. Medical teams at the University of Washington Medical Center told him to report immediately so they could begin preparing him for a heart transplant. The surgery began around midnight. It took surgeons about five hours to complete the transplant, Gloria Wildeman, a family friend, said Monday evening. She said she spent part of Sunday in the waiting room with Goforth’s family. Goforth was diagnosed earlier this year with congestive heart failure.

The microchip technology, created by a pair of University of Toronto scientists, will be able to determine the severity of the tumors through a simple urine sample and produce quick diagnosis with no need for painful biopsies. Now heading into its engineering stage, the portable device should be available for doctors’ use within two to three years and eventually could be tuned to detect a broad range of cancers and infectious ailments, the researchers say.

Special neurons in the brain send out a burst of dopamine in both negative and positive situations. However, the exact way in which dopamine neurons are wired and connected to the brain center called the hippocampus remains controversial among neuroscientists. Knowing exactly how the neurotransmitter dopamine shapes memory and behavior in association with an event or the surrounding environment is important to better understand such conditions as post-traumatic stress syndrome.“We showed in mice that a special circuit in the hippocampus has flexibility in combining with environmental input to shape behavior during an experiment in which the mice learn to avoid an unpleasant experience,” Dani said. “This is the first time that we have been able to show, as proof of principle, that the dopamine circuitry is also involved in learning to avoid aversive situations. ”Prevailing QuestionsIn previous animal experiments, when mice experience an unexpected reward, for example discovering a tube in which they can obtain a sugar-water treat, a burst of dopamine is emitted in the brain. The debate among neuroscientists centers on whether the neurotransmitter only shapes behavior when an animal is receiving a positive reward or if the neurotransmitter is also involved in shaping the way an animal learns how to avoid an uncomfortable situation.The team found that if the mice encounter an negative stimuli, a subgroup of neurons fires and releases dopamine in conjunction with the aversive environmental input. They also showed that when the dopamine signal to the hippocampus is chemically blocked in the mice, it prevents them from learning to avoid the negative stimulus. However, if the dopamine signal is chemically boosted in the mice, they remember to avoid the aversive event longer.“The bottom line of our study is that dopamine plays a role in both conditions, and that dopamine enables mice to learn and remember to avoid the negative situation, in this case avoid a light foot shock in one room of a two-room enclosure.” Share on Facebook LinkedIn Share Pinterest Share on Twitter Email The brain chemical dopamine regulates how mice learn to avoid a disagreeable encounter, according to new research from the Perelman School of Medicine at the University of Pennsylvania.“We know that dopamine reinforces ‘rewarding’ behaviors, but to our surprise, we have now shown that situations that animals learn to avoid are also regulated by dopamine,” said senior author John Dani, PhD, chair of the department of Neuroscience.The team’s findings are published this month in Cell Reports.

Taniguchi went wire to wire to claim his second title in as many weeks, wrapping up the week on 12-under-par 276 at The North Country Golf Club in Hokkaido. It was his 13th career crown on the Japanese tour and second of the year. GET THE BEST OF THE JAPAN TIMES IN FIVE EASY PIECES WITH TAKE 5
IN FIVE EASY PIECES WITH TAKE 5 Toyo never surrendered its lead and took the seventh, eighth and 10th legs en route to victory in a new record return-leg time of 5:25:38.Komazawa, which was aiming to complete a hat trick of ekiden titles after winning the national university championship and national invitational crown, was second, over 4 minutes back.Last year’s champion, Nippon Sport Science University, was third. Tokyo-Hakone Ekiden GET THE BEST OF THE JAPAN TIMES Toyo University held on to its overnight lead to win the Tokyo-Hakone men’s collegiate ekiden road relay for the first time in two years on Friday.Starting with a 59-second lead over Komzawa University after the first leg on Thursday, Toyo completed the 217.9-km round trip between Tokyo’s Otemachi business district and the spa resort of Hakone in Kanagawa Prefecture in 10 hours, 52 minutes, 51 seconds for its fourth overall title.
