first_imgTwo-time Canadian Olympian Tiffany Foster and her veteran partner, Victor, emerged victorious in the $86,000 CSI5* 1.50m Suncast Classic on Sunday, March 12, at the Winter Equestrian Festival (WEF) in Wellington, FL.Ireland’s Alan Wade set the track in the International Arena, which saw ten horse-and-rider combinations jump clear from the original 51-horse starting field. As the eighth rider to tackle the jump-off course, Foster used her long-time partnership with Victor to her advantage, stopping the clock in 36.82 seconds to take the win over two-time Olympic team gold medalist McLain Ward of the United States. Ward crossed the timers in 37.56 riding Tina la Boheme while fellow American Olympian Laura Kraut was third in a time of 38.75 seconds riding Constable.“Going late in the order is always an advantage in the jump-off,” said Foster, 32, of North Vancouver, BC. “McLain went right before me, and I knew the only way I could beat him was to take a risk and be faster to the last jump. I have huge trust and confidence in my horse and knew he could get there. I gave it a try, and I know the horse so well and he knows me, so it all worked out!”Remarkably, 2017 marks the eighth season that Foster has been partnered with Victor, a 15-year-old Dutch Warmblood gelding (Elmshorn x Grandeur) owned by Andy and Carlene Ziegler’s Artisan Farms and 2008 Canadian Olympic Champion Eric Lamaze’s Torrey Pine Stable. In fact, Foster had not even planned to enter Sunday’s $86,000 CSI5* 1.50m Suncast Classic until Andy Ziegler encouraged her.“My plan this week was for Victor to only jump in the WEF class on Thursday, but then I had a time fault and was so mad at myself,” explained Foster, who was one of five riders to jump Thursday’s $130,000 WEF Challenge Cup course clear only to be caught by the clock. “It wasn’t my plan to go again on Sunday, but Andy said I think you should do it and win it. I thought that sounded like a good idea, so he gets full credit for this win!“They are the best owners in the world, and it’s nice to be able to do well when they are here,” continued Foster, noting that both Andy and Carlene Ziegler were in attendance for Sunday’s win. “They never put too much pressure on us, and I think it makes us try even harder for them. I was really happy that Victor and I could deliver on a day when they were both here.”The partnership between Foster and Victor has produced strong results throughout the 12-week Winter Equestrian Festival, which still has three more weeks of competition to go. The pair also jumped double clear for the third-placed Canadian team in the $100,000 FEI Nations’ Cup at CSIO4* HITS in Ocala, FL, on February 17.In addition to Victor, Foster is developing a string of promising up-and-coming grand prix horses for Artisan Farms, including the ten-year-old Cadalora P and the nine-year-old Caipiranja.“I have a lot of nice young horses, and it’s great to develop them here,” said Foster of being based in one location for an extended period of time. “When they go in and do a good job, you feel a sense of accomplishment that they are on the right track.”Foster will continue to compete at the Winter Equestrian Festival, which concludes April 2, before relocating to Artisan Farms’ European base in Belgium for the spring season.

first_imgLinkedIn Email In fact, previous findings from the Burrone lab were the first to uncover that changes in AIS structure could alter the excitability of neurons to stabilise their overall electrical activity (Grubb & Burrone Nature 365:1070). What is less known is what happens to the unique synapses that form along the AIS, when this region of the axon is modified. “We know very little about these odd axonal synapses, other than they are in the right place to modulate neuronal output by acting directly on the axon initial segment”, says senior author Prof Juan Burrone, “but what happens when the AIS changes was, until now, a mystery”.This study shows for the first time that in slices of the hippocampus, a region of the brain known to be important for learning and memory, increases in neuronal activity causes the AIS to move away from the cell body, along the axon, by about half its length. The synapses however stay in place, causing a mismatch between the AIS and the synapses that control it.In collaboration with Dr Daniel Cattaert at the INCIA in Bordeaux, the authors used computational models to study the functional consequences of this arrangement. This approach revealed that the synapses that were left behind, those that lie in the gap between the cell body and the AIS, are particularly important for decreasing neuronal excitability, allowing neurons to remain functional even when under constant stimulation.As Dr Winnie Wefelmeyer, the leading author of this study puts it: “The axon initial segment is like the vocal chord of the neuron: without it, it would be unable to communicate. Changing the position of the AIS relative to the modulating synapses ensures that what the neuron is saying stays meaningful”. In biology, stability is important. From body temperature to blood pressure and sugar levels, our body ensures that these remain within reasonable limits and do not reach potentially damaging extremes. Neurons in the brain are no different and, in fact, have developed a number of ways to stabilise their electrical activity so as to avoid becoming either overexcitable, potentially leading to epilepsy, or not excitable enough, leading to non functional neurons.A new study published in PNAS by researchers from the MRC Centre for Developmental Neurobiology characterises a novel way in which neurons remain electrically stable when confronted with chronic increases in neuronal activity.The site at the centre of this control mechanism is a short segment of the axon, where electrical activity is initiated in the first place. Also known as the axon initial segment (or AIS for short), this remarkable structure is responsible for integrating all the information that a neuron receives via its synapses to produce an action potential, the electrical currency of information used by neurons. It is perhaps no surprise then that modulating this domain should have an important impact on a cell’s excitability. Share on Twittercenter_img Pinterest Share on Facebook Sharelast_img read more

first_imgJun 22, 2010 (CIDRAP News) – An informatics expert from the US Centers for Disease Control and Prevention (CDC) today spoke with clinicians about possible public health connections to electronic medical records, which she said could have been useful during the H1N1 pandemic and might ease information flow during future public health events.The discussion follows recent federal investments to promote greater use of health information technology.In March, Health and Human Services (HHS) Secretary Kathleen Sebelius announced the award of $162 million in economic stimulus funding designed to ease health information exchange and further health information technology (IT). The funding is part of a wider $2 billion effort to encourage more meaningful use of health IT and an electronic health record  (EHR) for every citizen by the year 2014, according to a Mar 15 HHS press release.In a clinicians conference call, Nedra Garrett, acting director of the CDC’s division of informatics practice, policy, and coordination, said recent health IT and EHR incentives present tremendous opportunities for public health. She said challenges are to connect public health alerts and guidance to relevant patient data in the EHR and to make sure systems have a meaningful impact on point-of-care practices, such as ordering lab tests and distributing educational information to patients.She said the CDC envisions working with other government agencies to employ other public health EHR-based IT applications such as food recalls and vaccine adverse event reporting.As an example of how the system would work, a patient presenting to a doctor’s office with flu symptoms such as cough, chills, and fever would generate an anonymous electronic patient profile containing the symptoms and the provider and patient’s zip code that transmit to a central alert repository, which would send the physician diagnosis, treatment, and prevention resources targeted to the patient.Garrett added that the anonymous patient profile could also include useful public health data such as the patient’s occupation or recent travel history.Having public health systems interface with EHR might be able to prevent clinicians from being bombarded during health emergencies, as they were during the H1N1 pandemic with multiple sources, some of which provided contradictory information.Garrett said clinicians will be most likely to find EHR-based public health alerts useful if they strike a balance of providing the most relevant information at the right time. She said an alert system would also likely include a severity scale to help clinicians gauge the urgency of the notices.Though the concept is still in its infancy, Garrett said the CDC has launched a small pilot program in an ambulatory setting. The CDC is collaborating with 10 providers of a GE Healthcare customer site in Chicago. The project is focusing on foodborne disease alerts, and Garrett said the CDC hopes to have preliminary findings by the end of the year.”Researchers can evaluate how often we need to trigger the alerts and how specific the information needs to be,” she said.During the question-and-answer part of the conference call, clinicians seemed eager to broaden the public health applications for EHR beyond just public health alerts to include functions such as surveillance and disease reporting. However, they also had concerns about local health and emergency medical service officials being included in the system, the scope of the information that the public health system might pull from medical records, and the interoperability between different EHR systems.Garrett said there are several complicated issues to sort out, such as making sure rules and governance issues are addressed. “We have more questions than answers, but we are moving in the right direction,” she said.See also:Mar 15 HHS press releaselast_img read more
