Cat Gets Intraosseous Transcutaneous Prosthetic Limbs

a8pe0pmd.jpgA Jersey cat, who had his back paws sliced off in an accident with a combine harvester, has received a pair of innovative prosthetic legs. Noel Fitzpatrick, a veterinary surgeon from Surrey, used a technique called intraosseous transcutaneous amputation prostheses (Itaps) to get the cat back on his feet. These prostheses grow through the skin in a way similar to the way deer antler bone does. This in contrast to the way most prosthetic limbs are attached by a “stump socket”, which often causes problems through rubbing and pressure sores. The new technology is currently being tested for application in humans. A documentary about the procedure called “The Bionic Vet” will be aired on BBC 1 this Wednesday.

Suitable Cage For Your Pets

To make the life of your pet becoming healthy and able to have a long life, it is important that you make them a place to live that is comfortable with the right pet house and products. Food supplies are not the only important thing that needs to be prepared for your pet; it is becoming an essential part in their life because it is believed to be able to enhance the pets lifespan. The special ones are made for special kinds of pet.

For one of a kind like a bird cage for the bird lover it is a dwelling for the pet that is deserved to be bought by the pet owners. A suitable environment for the bird to live can be prepared in planning the expected things that is needed inside the cage. The size of the cage is depending on the amount of the birds including the size of them so it can be well measured.

P.A.R.S. Watches Physical Activity in Youth


As the prevalence of childhood obesity continues to increase at an alarming rate amid an ever-growing array of sedentary distractions, finding ways to motivate kids to be active has never been more important or challenging. One innovative solution being marketed by NewWayFitness of Richmond, VA “[guarantees] increases in physical activity time or decreases in sedentary viewing time, among all children, without constant parent intervention.” The muscle behind this is the Physical Activity Reward System (P.A.R.S.) program, a web-based software system developed in cooperation with the Virginia Biotechnology Research Park that tracks the amount of time spent in physical activity. Physical activity is monitored and recorded throughout the day by a special watch, the Polar Activity Watch, and the information is transferred to P.A.R.S. Children and parents can then monitor activity levels within the web interface, tracking progress towards predefined goals and rewards. And in case positive reinforcement is not your style, the system may optionally cut power to appliances until those predefined goals are met.

Medtronic Innovation Center Is Like Medical Epcot

Here’s another report by Medgadget editor Dan Buckland from his trip to Minnesota to visit the headquarters of Medtronic.

To get a good idea of where Medtronic sees the future of medical information technology, go to Minneapolis and visit the Mounds View Bakken Education Center (note: you probably will need an appointment). It gives off the impression of Disney Epcot’s Tommorowland, complete with gift shop but with fewer kids around. The center is billed as a place where physicians come to meet with company employees to discuss products in development, partnerships and it’s where Medtronic demonstrates future concepts to gain feedback. Using high end computers, tablets, teleconferencing, advanced inventory tracking, and other tech, the Education Center speaks to the Medtronic’s prediction of the integrated OR of the near future. Open to internal Medtronic tours since October, the showroom places a heavy emphasis on a new IT infrastructure. A non-disclosure agreement prevents us from detailing the tech inside (a 2008 Star Tribune article describes it as having “two virtual catheterization labs to help train doctors and company field representatives”) but many non-medical tech brands are well represented and Medtronic has put together a very slick integrated health IT system from the looks of it.

Fuzzy Logic Used to Predict Cell Aging


Researchers from Drexel University and Children’s Hospital Boston are using “fuzzy logic” algorithms to better understand the complex mechanisms involved in cell aging. Fuzzy logic refers to algorithms that can handle imprecise input unlike the typical 0 or 1 digital nature of precise algorithms.

The study, which appears in the June issue of PLOS Computational Biology, relates progressive damage and dysfunction in aging, dubbed a vicious cycle, to inflammatory and metabolic stress response pathways. Interestingly, the activation of these pathways remodels the inner functioning of the cell in a protective and adaptive manner and thus extends lifespan.

This is the first time that scientists have applied fuzzy logic modeling to the field of aging. "Since cellular biodynamics in aging may be considered a complex control system, a fuzzy logic approach seems to be particularly suitable," said Dr. William Bosl, co-author of this study. Dr. Bosl, a staff scientist in the Informatics Program at Children’s Hospital Boston, developed a fuzzy logic modeling platform called Bionet together with a cell biologist, Dr. Rong Li of the Stowers Institute for Medical Research in Kansas City, to study the complex interactions that occur in a cell’s machinery using the kind of qualitative information gained from laboratory experiments.

Image: Several key processes related to biological aging can be described by positive feedback-loop motifs, as shown by this “vicious cycle” model. Metabolic fluxes (marked by blue lines) are initially in homeostasis. Reactive oxygen species (ROS) damage intracellular proteins including mitochondrial structures (red lines). This leads to impairment of ATP generation and biosynthesis, further increasing ROS levels. A portion of oxidized proteins is removed by autophagy, which constitutes a sink in this model.
