Measures to Take for Keeping your Pet Safe from Coronavirus

The deadly coronavirus outbreak has forced people to stay at their homes and distance themselves from one another. The global health emergency has put a pause on not just our lives but has equally affected our pet’s life. The impact of coronavirus on pets or whether they can transmit it to humans or other animals is yet uncertain, which makes the situation even more alarming for the pet owners. Be quarantined for so long is as boring for your pets as it is for you. Your pet needs your attention and love to remain safe. Other than the regular dog careroutine, you must follow some extra precautions to ensure their safety. (more…)

Markierte Zellen als Fenster in den Körper

Tübinger Forscher entwickeln Verfahren, das Zellen in Mäusen gezielt sichtbar macht und helfen könnte, Tierversuche zu reduzieren

Eine neue und besonders zuverlässige Methode zur Markierung von Zellen kann Forschungen zu Krankheiten wie Herzinfarkt, Diabetes oder Alzheimer vereinfachen und den Einsatz von Versuchstieren reduzieren: Wissenschaftlerinnen und Wissenschaftler der Universität Tübingen haben ein Verfahren entwickelt, mit dem sie bestimmte Zelltypen in Mäusen gezielt markieren und ihr Verhalten durch Positronen-Emissions-Tomografie (PET) verfolgen können. Mit dem „PET-basierten Cell Tracking“ kann man komplexe Lebensprozesse im Körper beobachten, ohne die Versuchstiere mit invasiven Methoden zu belasten. (more…)

Exploring the secret life of house sparrows with the aid of a 3D printer

Since it was introduced to North America in the late 19th century, the house sparrow has received little love. “Nothing can be urged in its favor,” declared an 1891 editorial in the New York Times. A few years later, the same newspaper deemed the birds “rats in the air.” Adding insult to injury, the International Union for Conservation of Nature has long kept the house sparrow on its unceremonious list of species of “least concern.” (more…)

UCLA brain-imaging tool and stroke risk test help identify cognitive decline early

UCLA researchers have used a brain-imaging tool and stroke risk assessment to identify signs of cognitive decline early on in individuals who don’t yet show symptoms of dementia.

The connection between stroke risk and cognitive decline has been well established by previous research. Individuals with higher stroke risk, as measured by factors like high blood pressure, have traditionally performed worse on tests of memory, attention and abstract reasoning. (more…)

UCLA Study First to Image Concussion-Related Abnormal Brain Proteins in Retired NFL Players

Technique may lead to earlier diagnosis, tracking of brain disorders in athletes

Sports-related concussions and mild traumatic brain injuries have grabbed headlines in recent months, as the long-term damage they can cause becomes increasingly evident among both current and former athletes. The Centers for Disease Control and Prevention estimates that millions of these injuries occur each year.

Despite the devastating consequences of traumatic brain injury and the large number of athletes playing contact sports who are at risk, no method has been developed for early detection or tracking of the brain pathology associated with these injuries. (more…)

The Search for the Earliest Signs of Alzheimer’s

Berkeley Lab scientists help paint a more complicated picture of the devastating disease

For the past five years, volunteers from the City of Berkeley and surrounding areas have come to Lawrence Berkeley National Laboratory to participate in an ongoing study that’s changing what scientists know about Alzheimer’s disease.

The volunteers, most over the age of 70, undergo what can best be described as a brain checkup. They’re asked to solve puzzles and memorize lists of words. Magnetic resonance imaging (MRI) scans image the structure of their brains in exquisite detail. Functional MRI scans allow scientists to watch portions of their brains light up as they form memories. And Positron emission tomography (PET) scans measure any accumulation of beta-amyloid, a destructive protein that’s a hallmark of Alzheimer’s. (more…)

MU Veterinary Surgeons Use Advanced MRI Technology to Locate Dangerous Tumor

Procedure saves therapy dog, beloved pet from cancerous brain tumor

COLUMBIA, Mo. ­— Using a special piece of MRI equipment, doctors from the University of Missouri College of Veterinary Medicine were able to remove a dangerous tumor from a beloved pet and therapy dog. Callie, an 8-year-old English Setter, began developing symptoms just a few days before being diagnosed with a tumor on her brain. Callie’s owner was referred to the neurological experts at MU, who performed a complicated procedure to remove the tumor from Callie’s brain. (more…)

UCLA Scientists Engineer Blood Stem Cells to Fight Melanoma

Researchers from UCLA’s cancer and stem cell centers have demonstrated for the first time that blood stem cells can be engineered to create cancer-killing T-cells that seek out and attack a human melanoma. The researchers believe the approach could be useful in about 40 percent of Caucasians with this malignancy.

Done in mouse models, the study serves as the first proof-of-principle that blood stem cells, which make every type of cell found in the blood, can be genetically altered in a living organism to create an army of melanoma-fighting T-cells, said Jerome Zack, the study’s senior author and a scientist with UCLA’s Jonsson Comprehensive Cancer Center and the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA.
