download Indian Express App More Related NewsFrom imaging babies to blasting apart kidney stones ultrasound has proved to be a versatile tool for physicians Now several research teams aim to unleash the technology on some of the most feared brain diseases The blood-brain barrier a tightly packed layer of cells that lines the brain’s blood vessels protects it from infections toxins and other threats but makes the organ frustratingly hard to treat A strategy that combines ultrasound with microscopic blood-borne bubbles can briefly open the barrier in theory giving drugs or the immune system access to the brain In the clinic and the lab that promise is being evaluated This month in one of the first clinical tests Todd Mainprize a neurosurgeon at the University of Toronto in Canada hopes to use ultrasound to deliver a dose of chemotherapy to a malignant brain tumor And in some of the most dramatic evidence of the technique’s potential a research team reports this week in Science Translational Medicine that they used it to rid mice of abnormal brain clumps similar to those in Alzheimer’s disease restoring lost memory and cognitive functions If such findings can be translated from mice to humans “it will revolutionize the way we treat brain disease” says biophysicist Kullervo Hynynen of the Sunnybrook Research Institute in Toronto who originated the ultrasound method Some scientists stress that rodent findings can be hard to translate to humans and caution that there are safety concerns about zapping the brain with even the low-intensity ultrasound used in the new study which is similar to that used in diagnostic scans Opening up the blood-brain barrier just enough to get a beneficial effect without scorching tissue triggering an excessive immune reaction or causing hemorrhage is the “crux” says Brian Bacskai a neurologist at Massachusetts General Hospital in Boston who studies Alzheimer’s disease and used to work with Hynynen Safely and temporarily opening the blood-brain barrier is a long-sought goal in medicine About a decade ago Hynynen began exploring a strategy combining ultrasound and microbubbles The premise is that ultrasound causes such bubbles to expand and contract jostling the cells forming the blood-brain barrier and making it slightly leaky EMMANUEL THVENOT/LAB OF ISABELLE AUBERT; COURTESY OF SUNNYBROOK RESEARCH INSTITUTE That could help cancer physicians such as Mainprize deliver chemotherapy drugs into the brain Hynynen also hypothesized that the brief leakage would rev up the brain’s inflammatory response against β amyloid—the toxic protein that clumps outside neurons in Alzheimer’s and may be responsible for killing them Disposing of such debris is normally the role of the microglia a type of brain cell But previous studies have shown that when β amyloid forms clumps in the brain it “seems to overwhelm microglia” Bacskai says Exposing the cells to anti bodies that leak in when the blood-brain barrier is breached could spur them to “wake up and do their jobs” he says Some antibodies in blood may also bind directly to the β-amyloid protein and flag the clumps for destruction Hynynen and others have recently tested the ultrasound strategy in a mouse model of Alzheimer’s In December 2014 for example he and colleagues reported in Radiology that the method reduces amyloid plaques in a strain of mice engineered to develop the deposits leading to improvements in cognition and spatial learning Microglia consumed more β amyloid after the treatment suggesting the cells do play a role in the effect says neuroscientist Isabelle Aubert who collaborates with Hynynen at Sunnybrook This week neuroscientist Jürgen Gtz of the Queensland Brain Institute in St Lucia Australia and his PhD student Gerhard Leinenga report that they have built on Hynynen and Aubert’s protocol using a different mouse model of Alzheimer’s After injecting these animals with a solution of microscopic bubbles they scanned an ultrasound beam in a zigzag pattern across each animal’s entire skull rather than focusing on discrete areas as others have done After six to eight weekly treatments the team tested the rodents on three different memory tasks Alzheimer’s mice in the control group which received microbubble injections but no stimulation showed no improvement Mice whose blood-brain barriers had been made permeable in contrast saw “full restoration of memory in all three tasks” Gtz says The team also found a two- to fivefold reduction in different types of β-amyloid plaques in the brain tissue of the treated group The attempt to stoke microglia’s appetite appeared to work; Gtz and Leinenga found much more β-amyloid protein within the trash-eating cells of treated animals Yet rousing microglia may not be the only mechanism responsible for the rodents’ memory boost Aubert notes She and Hynynen recently reported in Brain Stimulation that ultrasound also boosts the birth and growth of new neurons in mice Gtz and Leinenga next plan to test the whole-brain ultrasound scan method in larger animals with β-amyloid deposits such as sheep The approach which could in theory be used for other brain diseases involving abnormal protein clumps “is exciting” says Gerald Grant a neurosurgeon at the Stanford University School of Medicine in Palo Alto California “We’ve been thinking of opening up the blood-brain barrier as a way to get things into the brain but this pays attention to getting things out” It’s far from settled that eliminating β-amyloid deposits outside of neurons is the key to treating or stopping Alzheimer’s disease however And Bacskai is skeptical that the mouse results say much about the technique’s potential in humans The range between a mouse that can learn and one that cannot learn “is pretty small” so big gains in behavioral tests in mice may mean nothing in humans he says He adds that nonstandardized ultrasound equipment makes it hard to answer basic safety questions: “How long is the blood-brain barrier open How big are the pores What’s the damage” Hynynen who is working with a medical imaging company to commercialize the technique notes that ultrasound application to the brains of animals including rabbits and monkeys has produced no negative side effects And Mainprize’s clinical trial may provide more safety data He hopes to open the blood-barrier to increase chemotherapy delivery to a brain cancer patient just before he operates to remove the tumor Using Hynynen’s technology he and colleagues will apply ultrasound and microbubbles to tissue in and around the tumor as well as to several unaffected brain areas Then they’ll examine excised tissue for hemorrhages and to see if the treatment boosted the concentration of the drug A similar trial is now recruiting participants in France If these phase I trials establish safety “it opens the door for phase II trials looking to see if there’s any benefit” to opening the blood-brain barrier including for conditions beyond cancer Mainprize says Despite his doubts Bacskai can’t fully resist the dream driving this fledging field “Imagine if your grandmother went to the clinic once per year and it cleared amyloid β and that was all it took—no surgery no drugs It would be amazing”Written by ANI | Washington | Published: October 19 2010 11:08 am Related News Scientists have found how cocaine corrupts the brain and becomes addictive These findings are the first to connect activation of specific neurons to alterations in cocaine reward The results may help researchers in developing new ways of treating those addicted to the drug Led by Mary Kay LoboPostdoctoral Fellow in the Department of Neuroscience at Mount Sinai School of Medicine and first author of the studyresearchers found that the two main neurons (D1 and D2) in the nucleus accumbens region of the brainan important part of the brain’s reward centerexert opposite effects on cocaine reward Activation of D1 neurons increases cocaine reward whereas activation of D2 neurons decreases cocaine reward “The data suggest a model whereby chronic exposure to cocaine results in an imbalance in activity in the two nucleus accumbens neurons: increased activity in D1 neurons combined with decreased activity in D2 neurons This further suggests that BDNF-TrkB signaling in D2 neurons mediates this decreased activity in D2 neurons” said Dr Lobo The study was conducted using optogeneticsa technology to optically control neuronal activity in freely moving rodents Opposite cocaine reward similar to those found when activating each neuron is achieved by disrupting brain-derived neurotrophic factorwhich is a protein in the brain known for its involvement in neuronal survivallearningand memory and drug abuse

are really hard to feign New research from the University of California – Los Angeles found that people can fool others by pretending to laugh at their jokes just over one-third of the time When your fake laughs fall short of convincing tiny subtleties of your breathing are probably giving you away said Greg Bryant an associate professor of communication studies at UCLA “Quite a few fake laughs sound pretty good but listeners seem to pay attention to certain acoustic features that are really hard to fake” he said For the study published in the journal Evolution and Human Behavior Bryant recorded the spontaneous conversations of college roommates From these recordings he collected 18 spontaneous laughs which he considered to be genuine He then enlisted a different group of co-eds to laugh on command From this exercise he recorded 18 fake laughs of the same length as the real ones With Athena Aktipis a research scientist at UC San Francisco he then played the recordings to three groups of UCLA undergraduates In the first round the participants were asked to determine whether the laughs were real or fake and the students could usually tell the difference But they were fooled by 37 per cent of the fake laughs In the second round the researchers sped up the recordings and played them to a different group of college students Speeding up the laughter significantly increased the likelihood that both kinds of laughs were judged as genuine the researchers found When sped up the fake laughs fooled the study subjects half the time Bryant and Aktipis then dramatically slowed down the recordings and played them to yet another group of participants The researchers asked the students to figure out whether the sounds were made by humans or nonhuman animals The students couldn’t tell whether genuine laughs were human or not but they could tell that the fake laughs were made by people Bryant believes that the research illustrates that the two types of laughs – real and fake – are made by two separate vocalisation systems “Genuine laughs are produced by an emotional vocal system that humans share with all primates whereas fake laughs are produced by a speech system that is unique to humans” he said “Altering the speeds of the two types of laughs helps highlight the distinct properties of both vocal systems” he added For all the latest Lifestyle News
