Study shows early neutering poses health risks for German shepherds.

A new study conducted by researchers at the University of California, Davis (UC Davis), has found that spaying or neutering German shepherds before the age of 1 triples the risk of one or more joint disorders, particularly for cranial cruciate ligament tears, according to a university release. "Debilitating joint disorders of hip dysplasia, CCL and elbow dysplasia can shorten a dog's useful working life and impact its role as a family member," says lead investigator Benjamin Hart, DVM, PhD, DACVB, a distinguished professor emeritus in the UC Davis School of Veterinary Medicine, in the release. "Simply delaying the spay/neuter until the dog is a year old can markedly reduce the chance of a joint disorder." In the UC Davis study, researchers looked at veterinary hospital records for a 14.5-year period for 1,170 intact and neutered (including spayed) German shepherds for joint disorders and cancers previously associated with neutering. The diseases were followed through 8 years of age, with the exception of mammary cancer in females, which was followed through 11 years of age. Dogs were classified as intact, neutered before 6 months, neutered between 6 and 11 months, or neutered between 12 and 23 months. Joint disorders and cancers were of particular interest to the researchers because neutering removes male and female sex hormones that play key roles in processes such as closure of bone growth plates, the release states. The findings show that 7% of intact males were diagnosed with one or more joint disorders, as contrasted with 21% of males that were neutered prior to 1 year of age. Five percent of intact females were diagnosed with one or more joint disorders, while in females neutered before the age of 1 the percentage diagnosed rose to 16%. Mammary cancer was diagnosed in 4% of intact females, as compared to less than 1% of females neutered before 1 year. In intact females, urinary incontinence was not diagnosed at all; however, in females neutered before 1 year of age, it was diagnosed in 7% of cases. contributed by dvm360.

Silk screws and bone repairs.

Samuel Lin from Harvard Medical School and David Kaplan at Tufts University in Medford, Massachusetts have invented silk screws for bone repair. They made several researches over silk and molded the material into screw shapes. The silk screws are stronger than it seems and they can fix fractures and bone problems. When the silk is stretched it becomes as strong as steel ,this property makes the screws cut through bones. They are the best alternative to all previous suturing methods. The metal can corrode, and they need a second intervention. The other biodegradable alternatives can cause severe inflammation while the polymers are too soft and need drilling the bone.(coolweird.com) The silk screws are the only bone screws that are strong enough, naturally biodegradable and while they biodegrade don’t cause inflammation. Ideally, they could be used in place of metal plates and fasteners in many circumstances. That would mean no more setting off detectors or experiencing pain when cold temperatures set in. This could also be of great benefit to overall healing, as using metal in the body has been observed to slow wound healing and assist the rapid development of infection. In cases where permanence isn't needed, silk is being touted as an ideal alternative to traditional materials especially since, over time, it dissolves in the body.

Bio pen: a hand held 3D printing pen for surgery.

BioPen is a handheld 3D printer which allows surgeons to precisely design and deliver customized bone and other implant materials (live stem cells and growth factors) at the time of surgery to regenerate bone, cartilage, muscle, or nerve tissue. The University of Wollongong (UOW) in Australia developed a handheld device is designed to let surgeons “draw” live cells and growth factors directly onto the site of an injury to help accelerate the regeneration of functional bone and cartilage. The BioPen extrudes cell material inside a biopolymer Instead of plastic filament,such as alginate, which is in turn encased in an outer layer of gel material. Both the outer and inner layers are combined in the pen head as it is extruded and the surgeon “draws” to fill in a section of damaged bone. When the surgeon draws with the BioPen, the two layers of gel are combined in the pen head as they are are extruded onto the bone surface to fill in the damaged bone section. Then, an ultraviolet light source solidifies the materials, providing protection for the embedded cells as they are built up layer-by-layer to construct a 3D scaffold in the wound site. Once the cells are drawn onto the surgery site, they will multiply, become differentiated into nerve cells, muscle cells, or bone cells, and eventually develop from individual cells into a thriving community of cells in the form of functioning tissue.

Giant fish that eats crocodiles and humans.

During a fishing expedition on the River Congo in Africa, British angler Jeremy Wade, 52, caught Goliath tigerfish. Goliath is considered one of the largest freshwater fish in the world. It is much larger and more deadly than the small piranha. The giant fish has 32 teeth that are similar in size to those of a great white shark, and it has been proven that it attacks humans and crocodiles. When people name something or someone Goliath, you better expect to see something humongous! Well that is clearly the case of the Goliath tigerfish. The biggest monster fish from this species caught up until now was 5 feet long and weighed 154 pounds, but there are indications that even much bigger specimens roam the Lualaba River, Lake Upemba and Lake Tanganyika in Africa Each of this monster’s razor-sharp teeth can be up to one inch long, and when these “knives” gulp on the unsuspecting prey, expect a clean cut. The Goliath tigerfish species takes extremely long to breed, because, they like to hunt, and eat a lot, hence, they invest their energy into killing, rather than breeding. Your first instinct when you catch such a fish would be to take it home and frame it, please do not, cause we have to preserve the species, or else, we’ll only see it in documentaries.

A beautiful aquarium fence in Turkey.

Mehmet Ali Gökçeoğlu decided to build the coolest aquarium for his pet fish in his luxurious villa in Turkey. He went overboard and built the famous aquarium out in the open, in the form of a 50 meter long fence, surrounding his home. The wacky idea cost the millioniare plenty of thousands of dollars, but pretty soon, he saw his dream come true. The fence was a “fully furnished” aquarium, home to more than 1,000 fish, but also a few octopuses. The 50-meter-long aquarium has become a regular tourist attraction, and thousands of visitors come every day to admire the wondrous fish-fence. The hardest part of making the aqua-ence was connecting it to the Aegean sea with the aid of a 400-meter-long underground pipeline. This humongous conduct continuously changes the water, that is why it looks crystal clear and the fishes are extremely happy. The total amount spent on this cool aquarium fence was $21,000, but still has several costs with security and maintenance. The stunning aqua-fence is kept safe with the aid of more than 17 facial recognition security cameras. Visitors which line-up to see this cool, man-made structure are allowed to take pictures, or even film the aqua-fence, but if they come too close, they risk setting off an alarm.

GENETICALLY MODIFIED BULLS TO BOOST FOOD SECURITY.

 The coolweirdo.com shows how genetic selection and experiments with the Belgian Blue has produced a humongous species of bulls packed with muscles and meat.

The reason these animals are getting so big is due to a very big genetic defect of a faulty myostatin gene, which is responsible for the gigantic size and double muscling.

  This amazing super species of cattle is known to have more than 40% additional muscle mass. They gain weight very fast, and produce high protein milk for their calf. Exploiting the rapid growth rate may provide an inroad to food security.

X-RAY GLASSES ALLOWS DOCTORS TO SEE BELOW THE SKIN.

Awesome X-Ray Glasses Let Doctors See Through the Skin. A new medical invention could allow doctors and medical staff to view what lays behind your skin.Eyes-On Glasses System is a new super-smart device developed by Evena Medical, an imaging technology firm. We all know that when it comes to taking blood, the hardest part is finding a vein. Well, that burden is why the awesome X-Ray vision glasses were invented. The glasses consist of a head-mounted device with a display which is equipped with vascular imaging technology. The company has managed to integrate technology into glasses, and a hands-free system projects overlays of digital content onto the user’s field of vision. As it X-ray vision alone weren’t enough, the super glasses are also able to store the information in order to make the documentation of vein condition throughout the patient’s hospital stay more accessible. If that doesn’t make whomever is using these glasses feel like they have superpowers, then maybe the fact that the glasses an also interact with any electronic medical records. Studies indicate that in nearly 40% of the cases, the first attempt to start an IV line fails, leading to the discomfort of the patient. That being said, the new device promises wonders! The amazing technology is actually the result of a combination between Evena’s multi-spectral 3D imaging technology with Epson’s Moverio smart glasses. Eyes-On system is designed to automatically log all of the collected data from each procedure and stores it with the rest of the patient’s medical records. With the aid of Moverio’s Wi-Fi connectivity, everything that the nurse sees can easily be shared with doctors anywhere worldwide. Contributed by Coolweirdo.com
