Mountain Ridge Animal Hospital and Pain Management Center of Lafayette, Colorado Helps Local Shepherd Manage the Pain …

Posted on by

Poway, California (PRWEB) February 20, 2014

Four-and-a-half year old Dakota, a German Shepherd from Colorado, is managing the pain from osteoarthritis with the help of stem cell therapy thanks to Mountain Ridge Animal Hospital and Pain Management Center of Lafayette. Dakotas positive results showed almost immediately, and just a few months post stem cell therapy using Vet-Stem, Inc. services, he is doing activities that he has not done for years.

Dakota was diagnosed with hip dysplasia at just three years old, and in less than two years time his owners felt his quality of life had significantly started to deteriorate. Robert Landry, DVM at Mountain Ridge Animal Hospital and Pain Management Center has been doing regenerative cell therapy with Vet-Stem for six years, treating various types of orthopedic issues and arthritis in small animals, and determined Dakota was a good candidate for the procedure.

Dr. Landry began Dakotas procedure on a Tuesday in October by collecting a small sample of fat called the falciform fat pad, which was sent overnight to Vet-Stems lab in San Diego, California. Received the next morning, the lab processed Dakotas fat and created injectable doses of his own stem cells to be overnighted back to Dr. Landry. Thursday Dakota received his hip injections and recovery began.

Dakotas results were almost immediate, Dakotas owners expressed, He moves around with ease now and can even go up and down the stairs. Last week he jumped into the back of my SUV, which he hasn't done in years. Before the stem cell therapy Dakota never wagged his tail, and now he doesnt stop! His quality of life is so much better and he seems truly happier.

Dr. Landry and the team at Mountain Ridge Animal Hospital and Pain Management Center specialize in companion animal health care, striving to provide the highest quality in Veterinary health care and customer service. Some of their specialties are pain management, surgery, and regenerative medicine. By understanding and valuing the special role that pets play in a family Dr. Landry and team are genuine advocates for each pet's health and care.

About Vet-Stem, Inc. Vet-Stem, Inc. was formed in 2002 to bring regenerative medicine to the veterinary profession. The privately held company is working to develop therapies in veterinary medicine that apply regenerative technologies while utilizing the natural healing properties inherent in all animals. As the first company in the United States to provide an adipose-derived stem cell service to veterinarians for their patients, Vet-Stem, Inc. pioneered the use of regenerative stem cells in veterinary medicine. The company holds exclusive licenses to over 50 patents including world-wide veterinary rights for use of adipose derived stem cells. In the last decade over 10,000 animals have been treated using Vet-Stem, Inc.s services, and Vet-Stem is actively investigating stem cell therapy for immune-mediated and inflammatory disease, as well as organ disease and failure.

Zebrafish Discovery May Shed Light on Human Kidney Function

Newswise ROCHESTER, Minn. Feb. 20, 2014 Researchers say the discovery of how sodium ions pass through the gill of a zebrafish may be a clue to understanding a key function in the human kidney. The findings from a collaboration between Mayo Clinic and the Tokyo Institute of Technology appear in the online issue of the American Journal of Physiology-Regulatory, Integrative and Comparative Physiology.

The researchers discovered a protein responsible for gas exchanges in the fish gill structure. Specifically they studied and characterized the Na+/H+ (sodium/hydrogen) exchanger named NHE3, responsible for controlling sodium and hydrogen ions across the gill. The researchers also directly demonstrated that NHE3 can function as a Na+/NH4+ (sodium/ammonium) exchanger.

This is significant because the fish tends to mimic the process in humans, says Michael Romero, Ph.D., a Mayo Clinic physiologist who works in nephrology. This is the true beauty of comparative physiology- a lot of the organs function by very similar processes, down to ionic transfer.

In this case the protein allows the sodium ions to be absorbed from the forming urine while at the same time discarding waste from normally functioning cells, thus keeping the body in balance and serving as an energy saving system. The researchers say the same NHE3 protein performs a similar function in the intestine, pancreas, liver, lungs and reproductive system.

The gill is used in the fish as a transport system: sodium ions are nutrients and ammonium carries away waste. Its a key process allowing zebrafish to extract sodium ions from fresh water. In humans, NHE3 is involved in the acid-waste control system in the kidney, but there hasnt been a good analysis of that process in humans. Part of this acid-control process in the human kidney is ammoniagenesis which requires the initial part of the kidney tubule (proximal tubule) to export ammonia/ammonium. Physiologically, it has been assumed that NHE3 can perform a Na+/NH4+ exchange, but this has never been experimentally demonstrated.

Ammoniagenesis and increased renal sodium bicarbonate absorption are partly under the control of the renin-angiotensin-aldosterone system (RAAS), which means that this work enhances understanding of human hypertension. Researchers say their results in fish can be a clue or starting point for analyzing the process in people. Researchers say they hope to continue their work in other species and ultimately further describe the process in humans.

The research was funded by both institutions. Co-authors include Yusuke Ito, Akira Kato, Ph.D., and Shighisa Hirose, Ph.D., all of the Tokyo Institute of Technology; and Taku Hirata, Ph.D., of Mayo Clinic. Yusuke Ito was a visiting graduate student at Mayo Clinic. Dr. Akira Kato is a visiting research collaborator with Dr. Romero at Mayo Clinic. ### About Mayo Clinic Recognizing 150 years of serving humanity in 2014, Mayo Clinic is a nonprofit worldwide leader in medical care, research and education for people from all walks of life.

Why are some children more resilient to post-traumatic stress?

New Rochelle, NY, February 20, 2014Children exhibit a range of responses to traumatic events such as natural disasters, with some suffering acute traumatic reactions that resolve over time and others experiencing long-term symptoms of post-traumatic stress. Identifying factors that may help predict which youths are at greater risk of more serious disorders and which are likely to be more resilient following a traumatic event can help determine the care and services needed, according to an article in Journal of Child and Adolescent Psychopharmacology (JCAP), a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is part of a special issue on pediatric traumatic stress that is available on the JCAP website.

In the article "Resilience and Trajectories of Post-traumatic Stress Among Youth Exposed to Disaster," Carl Weems, PhD and Rebecca Graham, University of New Orleans, LA, compare post-traumatic stress (PTS) symptoms among children exposed to both hurricanes Katrina and Gustav and describe the different risk factors and coping styles associated with resiliency to PTS.

Guest Editors Judith Cohen, MD, Drexel University, Philadelphia, PA, and Michael Scheeringa, MD, Tulane University, New Orleans, LA, emphasize the importance of recognizing the similarities and differences in how children and adults react to traumatic events, and the effect that family dynamics and caregivers can have on treatment strategies and their outcomes in the Journal's Editorial.

In another article, authors Richard Meiser-Stedman, PhD, et al., MRC Cognition & Brain Sciences Unit, Cambridge, U.K., and King's College and King's College Hospital, London, caution against using certain cognitive strategies aimed at blocking trauma-related memories in adults and adolescents in the article entitled "Thought Control Strategies and Rumination in Youth with Acute Stress Disorder and Post-traumatic Stress Disorder Following Single-Event Trauma."

In "Perceived Parenting Change and Child Posttraumatic Stress Following a Natural Disaster," Vanessa Cobham, PhD and Brett McDermott, MD, University of Queensland, Brisbane, Australia, identify a link between specific parenting practices and increased risk for PTS symptoms among the children in a household following a natural disaster.

Harold S. Koplewicz, MD, Editor-in-Chief of JCAP, and President, Child Mind Institute, New York, NY, states that there is a "palpable shift in the profession towards considering even sub-threshold PTS symptoms a worthy target of intervention in kids who have experienced a possible traumatic event, such as natural disaster or violence. Even children who do not meet specific criteria in terms of how they response to trauma may warrant careand this care can be helpful. This work is of particular importance in light of recent school shootings and natural disasters."
