He was an Army platoon leader, performed reconnaissance missions and served in three infantry regiments.<\/p>\n<p>In 1948, a year after the Air Force became its own military branch, Guerra enlisted again and served 28 more years, including duty in Korea and Vietnam.<\/p>\n<p>\u201cHe did three wars,\u201d Robert Guerra said, and for this Guerra earned Purple Heart and Bronze Star medals.<\/p>\n<p>But it\u2019s a time that his father sometimes struggles to remember.<\/p>\n<p>Described as having a Type A personality, Ramiro Guerra can no longer \u201cconnect the dots\u201d cognitively, his son said. \u201cHe can see his decline, and it bothers him.\u201d<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-3105 size-full\" src=\"https:\/\/magazines.uthscsa.edu\/mission\/wp-content\/uploads\/sites\/7\/2015\/06\/RamiroGuerra_hat_quote.jpg\" alt=\"Ramiro Guerra, 90, is a triple-war veteran.

We should be able to do this [trial] fairly quickly,\u201d said Dean L. Kellogg Jr., M.D., Ph.D., professor of medicine and the principal investigator of the rapamycin study.<\/p>\n<p>\u201cBut how can researchers study life span in humans? A lot of times, the subjects will live longer than the researchers. So we are looking at proxies for life span.\u201d<\/p>\n<p>The first clinical trial was conducted in 2013 at the Audie L. Murphy Memorial VA Hospital by researchers from the Barshop Institute.<\/p>\n<p>Ramiro Guerra and seven other male veterans, aged 80 to 95 years old and in relatively good health, were immunized for hepatitis B\u2014chosen as a marker to determine an improvement in immune systems. Then the veterans were split into two groups. One group, including Guerra, received rapamycin; the second group received an inactive placebo. The trial lasted four months.<\/p>\n<p>Researchers recorded any changes in the veterans\u2019 physical functions, such as walking speed and hand-grip strength. They also documented changes in their cognitive functions such as decision making, learning and memory. They continue to study antibody responses to see if they were more robust during treatment with rapamycin.<\/p>\n<p>\u201cIf we can demonstrate an effect on an age-related process, such as rejuvenating immune function or improving physical or cognitive function, then that will suggest rapamycin has a life-span function, as well,\u201d Dr. Kellogg said.<\/p>\n<p>Rapamycin was approved for use as an immunosuppressant in transplant patients in 1999. For years its value was debated\u2014many scientists thought rapamycin might do as much harm in people as good.<\/p>\n<p>\u201cRapamycin has been used in transplant patients who are very ill and receive many medications. I have found there is a clinical bias against it, that it causes diabetes or raises lipids [fats in blood]. This is based on studies from transplant patients,\u201d Dr. Kellogg said.<\/p>\n<p>\u201cVery few studies have done work with rapamycin as a single agent in relatively healthy persons,\u201d he said. \u201cWe\u2019ve found it to be a well-tolerated drug, and there were no changes in the blood sugars and only a mild increase in triglyceride [lipid] levels, but this change was the same as in the placebo group.\u201d<\/p>\n<p>If clinical trials demonstrate rapamycin\u2019s value as an intervention to improve health span, the drug would then need to gain Food and Drug Administration approval for use in healthy people. Health span refers to the years of good health a person enjoys across the life span.<\/p>\n<div id=\"attachment_3097\" style=\"width: 683px\" class=\"wp-caption alignright\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-3097\" class=\"wp-image-3097\" src=\"https:\/\/magazines.uthscsa.edu\/mission\/wp-content\/uploads\/sites\/7\/2015\/06\/RamiroGuerra_20150505_2470.jpg\" alt=\"Cindy Holmes and Robert Guerra have seen their 90-year-old father, Ramiro Guerra, slowly lose his memories as he ages.

Sadly, the family noticed after the study that the effects went away, although it is not known why, said Dr. Kellogg. That is one of the mysteries Dr. Kellogg hopes to solve as clinical trials continue. He and his team are applying for additional funding to continue the human research.<\/p>\n<p>\u201cIt wasn\u2019t a magic pill, but we did see some improvement in his cognitive abilities,\u201d Robert Guerra said.

As a recipient of the Claude D. Pepper Older American Independence Center grant from the National Institute of Aging (NIA), the Barshop Institute is now comprehensive, said Barshop Institute Director Nicolas Musi, M.D., a physician-scientist in the areas of aging and metabolic disease.<\/p>\n<p>The Pepper Center designation, expected to bring as much as $3.5 million over five years, enables translation of research into practical applications in the lives of older Americans. It joins another NIA award, also totaling $3.5 million over five years. The Health Science Center received a perfect score on its renewal application for the Nathan Shock Center of Excellence in the Biology of Aging. This will provide core services and support for aging research and education.<\/p>\n<p>These new grants ensure that the research geared toward improving how people age will continue and expand over the next several years, Dr. Musi said.<\/p>\n<\/div>\n<div class=\"col nomargin\">\n<p><img decoding=\"async\" class=\"img-frame alignleft\" src=\"https:\/\/magazines.uthscsa.edu\/mission\/wp-content\/uploads\/sites\/7\/2015\/06\/aging.png\" alt=\"\" width=\"600\" \/><\/p>\n<p>\u201cWe will be unique in the country in our capacity to investigate the aging process and move our findings into the clinic,\u201d he said.<\/p>\n<p>The Barshop Institute became one of a handful of centers in the country to have a Shock Center in 1995, and has maintained the designation ever since,\u00a0receiving more than $18 million in funding.<\/p>\n<p>\u201cA very small number of these centers are able to secure the NIA Shock Center funding,\u201d Dr. Musi said. \u201cIt is the equivalent of a National Cancer Institute\u00a0designated cancer center in terms of stature in the world of aging research.\u201d<\/p>\n<p>The Barshop Institute is also one of only three centers in the NIA Interventions Testing Program and last year received funding of $7.5 million through 2019.

The Barshop Institute for Longevity and Aging Studies at the UT Health Science Center is even looking at the fitness of this rural Texan.<\/p>\n<p>At 91 years old, Burton is running 15 head of cattle at his 500-acre ranch near Junction, Texas. In the late fall, he\u2019ll take his cattle to market about 60 miles east in Fredericksburg.<\/p>\n<p>\u201cI raise exotic game and cattle and at times take goats out there,\u201d he said. \u201cIt keeps me busy; there\u2019s always something to do. It keeps me physically active.\u201d<\/p>\n<p>Burton was among the first eight veterans to participate in a clinical research study of the drug rapamycin. The study, conducted by the Barshop Institute and the South Texas Veterans Health Care System, is testing the drug as a possible intervention for aging. Dean Kellogg, M.D., Ph.D., and other faculty in the Long School of Medicine are studying test results from Burton and the other veterans to assess whether rapamycin improved their physical ability, immune system function, and learning and memory.<\/p>\n<p>\u201cI happened to go down to the San Antonio VA to a prisoner-of-war clinic,\u201d Burton said. \u201cWhile I was there, Dr. Kellogg came up and told me something about the study and asked if I would be interested. I said yes, if it would make me livelier.\u201d<\/p>\n<p>Burton served 23 years in active duty in the Air Force and five in the Air Force Reserves. He went through pilot training during World War II and was disappointed to be assigned to the training command as an instructor.<\/p>\n<p>\u201cI wanted to be in the sky, like Snoopy chasing the Red Baron,\u201d he said.<\/p>\n<p>During the Korean War, he got his wish. But while flying an F-84 fighter-bomber, he was shot down by anti-aircraft fire. The loneliest and coldest winter of his life ensued.<\/p>\n<p>Burton was a POW from 1952 to 1953.<\/p>\n<p>\u201cI was a guest of the Chinese Communists for 10 months,\u201d he said. \u201cIt was way up north, just across the Yalu River from China. It is very cold up there\u2014I always thought that\u2019s where Admiral Byrd [Richard Byrd, 1888-1957] went to train for his cold-weather operations at the South Pole.\u201d<\/p>\n<p>After his release in 1953, he returned to his hometown of Kerrville, Texas. The 29-year-old war hero was welcomed with a parade, where, incidentally, he would meet his future wife, Betty, for the first time.<\/p>\n<p>\u201cI\u2019ve known him since I was 9,\u201d said Betty Burton. \u201cMy father said, \u2018We\u2019re going to see this local man who came home.\u2019 I remember that day.\u201d<\/p>\n<p>After his active duty, Allie Burton retired in Kerrville and became a real estate broker. He realized his lifelong dream when he was able to buy the ranch, in addition to a house in Ingram where he stays when not at the ranch.<\/p>\n<p>He and Betty were married in 1997\u201444 years after they met. He has two children and she has three. Together they have nine grandchildren and six great-grandchildren.<\/p>\n<p>\u201cWe have \u2019em every day. Someone is always here,\u201d he said.<\/p>\n<p>Allie Burton is a dancer who always walks fast, his wife said. They enjoy country dancing in area dance halls, from Bandera to Fredericksburg to Hunt.<\/p>\n<p>But last year, there was a change in her husband, Betty Burton said. He was lying down two to three times during the day because he was tired.<\/p>\n<p>\u201cAfter taking rapamycin for a length of time, he quit lying down so often,\u201d she said.<\/p>\n<p>It\u2019s impossible to base a therapy for aging on anecdotal stories. Dr. Kellogg pointed out that only a few volunteers have received the drug, and more study is needed. He and other School of Medicine researchers are seeking additional funding to expand the study.<\/p>\n<p>The Burtons agree that whatever is learned about rapamycin will prove to be important.<\/p>\n<p>\u201cI would like to think that I can help humanity in some way, if that\u2019s what it comes to, and that my grandkids and great-grandkids could benefit from that,\u201d Allie Burton said.<\/p>\n<\/div>\n<p><a href=\"#top\">Back to top<\/a><\/p>\n<p>\n<\/div><\/div>\n<p>&nbsp;<\/p>\n<div id=\"timeline\">\n<div class=\"section-full-width section-dark-bg\" style=\"background-color:#f5f3e4;\" id=\"barshopinstitute\"><div class=\"section-boxed\" style=\"color:#000000;\"><h2 class=\"section-title\" style=\"color:#000000;\">Barshop Institute<\/h2><h4 style=\"color:#000000;\" class=\"sub-title\">Through the years<\/h4><\/p>\n<div class=\"cols-wrapper cols-2\">\n<p><strong>1970s, 80s and 90s<\/strong> \u2013 Research in basic science departments of the Health Science Center includes a strong focus on dietary calorie restriction and its effects on aging in mice, conducted by pioneers such as Edward J. Masoro, Ph.D.<\/p>\n<p><strong>1992 <\/strong>\u2013 The Aging Research and Education Center (AREC), the forerunner of today\u2019s Barshop Institute, is established. Arlan G. Richardson, Ph.D., was the founding director.<\/p>\n<p><strong>1995 <\/strong>\u2013 The AREC is one of the first centers in the country to be named a Nathan Shock Center of Excellence in the Biology of Aging, a designation the Barshop Institute retains today. Shock Centers are funded by the National Institute on Aging (NIA) of the National Institutes of Health. They provide leadership in the pursuit of basic research into the biology of aging.<\/p>\n<p><strong>2001 <\/strong>\u2013 The University of Texas System Board of Regents approves the honorific name: The Sam and Ann Barshop Institute for Longevity and Aging Studies. Mr. Barshop served on the Board of Regents previously, and he and Mrs. Barshop were generous donors to aging research at the Health Science Center. Other donors to the institute included The Brown Foundation Inc. and the UT System.<\/p>\n<p><strong>2004 <\/strong>\u2013 The NIA selects three U.S. centers, including the Barshop Institute, to participate in the NIA Interventions Testing Program (ITP). The centers investigate treatments that have the potential to extend life span and delay disease and dysfunction in mice. Randy Strong, Ph.D., is principal investigator of the ITP at the Barshop Institute.<\/p>\n<p><strong>2004 <\/strong>\u2013 A Health Science Center researcher, Z. Dave Sharp, Ph.D., proposes rapamycin, a medication used in transplant and other patients, to be studied in the ITP. Dr. Sharp later wins the Mprize Lifespan Achievement Award from the Methuselah Foundation for his foundational ideas about rapamycin\u2019s potential effects in aging.<\/p>\n<p><strong>2005 <\/strong>\u2013 The Barshop Institute building is dedicated. Mr. and Mrs. Barshop are joined by keynote speaker Sen. Kay Bailey Hutchison and many faculty and dignitaries for the celebration.<\/p>\n<p><strong>2005 <\/strong>\u2013 Drs. Strong and Sharp run into a problem studying rapamycin: It is not stable enough in food to register in the blood level of mice. This causes a delay in the mouse studies. Dr. Strong works with Southwest Research Institute to microencapsulate rapamycin, making it feasible to do animal studies. Because of the delay, rapamycin is studied in mice that are 20 months old \u2013 the equivalent of 60 years of age in humans.<\/p>\n<p><strong>2009 <\/strong>\u2013 Results of the ITP study of rapamycin in mice of both sexes are published in the prestigious journal <em>Nature. <\/em>The rapamycin formulation developed by Dr. Strong extends the maximum life span of the middle-aged mice by 28 percent to 38 percent. This is the first pharmaceutical intervention shown to extend longevity in mice; previously only dietary calorie restriction and genetic manipulation had been successful.<\/p>\n<p><strong>2010<\/strong> \u2013 Veronica Galvan, Ph.D., of the Health Science Center, publishes results showing that administration of rapamycin improves learning and memory in a strain of mice engineered to develop Alzheimer\u2019s-like deficits.<\/p>\n<p><strong>2013<\/strong> \u2013 Rapamycin enters human clinical trials, with four military veterans receiving the drug and another four receiving a placebo.
