“I HOPE THIS STUDY CHANGES THE DIALOG AROUND HERPES RESEARCH AND OPENS UP THE IDEA THAT WE CAN START THINKING ABOUT CURE, RATHER THAN JUST CONTROL OF THE VIRUS.”

In a landmark study, researchers have successfully used gene editing to remove the oral herpes virus (HSV-1) in mice.

While previous research has mostly focused on treating and suppressing the sometimes painful symptoms of herpes, this study took a more radical approach by attempting to eliminate the virus altogether.

For decades, greater than 60% of the human genome was believed to be “junk DNA” that served little or no purpose in the course of human development. Recent research by Colorado State University is challenging this notion to show that junk DNA might be important after all.

A new study, published on June 5 in Aging Cell, found that a portion of noncoding genetic material, called repetitive element transcripts, might be an important biomarker of the aging process.

Tom LaRocca, an assistant professor in the Department of Health and Exercise Science and faculty member in the Columbine Heath Systems Center for Healthy Aging at CSU, led the study to investigate a growing body of evidence that repetitive elements—transposons and other sequences that occur in multiple copies in the human genome —may become active over time as we age.

Newswise — Most of modern medicine has physical tests or objective techniques to define much of what ails us. Yet, there is currently no blood or genetic test, or impartial procedure that can definitively diagnose a mental illness, and certainly none to distinguish between different psychiatric disorders with similar symptoms. Experts at the University of Tokyo are combining machine learning with brain imaging tools to redefine the standard for diagnosing mental illnesses.

“Psychiatrists, including me, often talk about symptoms and behaviors with patients and their teachers, friends and parents. We only meet patients in the hospital or clinic, not out in their daily lives. We have to make medical conclusions using subjective, secondhand information,” explained Dr. Shinsuke Koike, M.D., Ph.D., an associate professor at the University of Tokyo and a senior author of the study recently published in Translational Psychiatry.

“Frankly, we need objective measures,” said Koike.

First, we found that every cancer organoid retains the properties of the tissue of origin, so this shows that if the samples were obtained from the surgery of a colon or pancreatic cancer, the organoid closely resembles the original primary tumor. Second, we discovered that there is no contamination of normal cells, thus, the malignant pure transformed cells can be analyzed without interferences. And finally, the 3D organoid cancers are closer to the patient tumors than the commonly used 2-D cell lines.

Scientists have used 3D models to break down the DNA behavior of cancer cells, in a breakthrough new study which could revolutionize treatment for the disease.

In what is a first for science, a research team led by Dr. Manel Esteller, Director of the Josep Carreras Leukaemia Research Institute (IJC), demonstrated how 3D models (known as organoids) can now be used to develop a characterization of the DNA make-up—or the epigenetic fingerprint—of human cancer.

Both genetic and non-genetic factors underlie the intratumoural heterogeneity that fuels cancer evolution. This Review discusses the application of single-cell multi-omics technologies to the study of cancer evolution, which capture and integrate the different layers of heritable information and reveal their complex interplay.

Every dog owner has their own reasons for getting a pet, whether it is companionship, protection, or simply to have a furry friend to walk with. Each different breed comes with perks and challenges, and owners must be prepared to accommodate each type of dog’s unique health requirements to maximize their lifespan, because the reality is that some dogs are genetically predisposed to live much longer than others.

In order to determine the shortest and longest living dog breeds in the world, 24/7 Tempo reviewed the study, “Methods and mortality results of a health survey of purebred dogs in the UK,” published in the Journal of Small Animal Practice. Breeds for which there was little data or low response rates on surveys sent to owners were not considered. Breeds that are not officially recognized by the American Kennel Club were also not considered. Breed popularity data, as well as height and weight data, comes from the AKC. The height refers to the height of the dog’s shoulder.

Numerous studies have determined that there is a significant link between the size of a dog and the length of its lifespan — larger dogs have noticeably shorter lifespans than smaller dogs, as they age at a faster rate. Yet size and lifespan do not correlate exactly, as certain types of dogs are especially prone to maladies like cancer or heart problems.

Background:Pantoea is a genus within the Enterobacterales whose members encompass free-living and host-associated lifestyles. Despite our growing understanding of the role of mobile genetic elements in the biology, ecology, and evolution of this bacterial group, few Pantoea bacteriophages have been identified and characterized.

The high demand on medical devices and personal protective equipment (PPE) during the COVID-19 crisis left millions of health care professionals unprotected in the middle of this situation, as governments around the world were not prepared for such pandemic. The three-dimensional printing (3DP) community, from universities to 3DP enthusiasts with printers at home, was there to support hospitals from day 1 on this demand by providing PPE and other medical supplies (e.g., face shields and valves for respiratory machines). This editorial covers the importance of 3DP in the fight against COVID-19 and how this can be used to tackle potential pandemics and support the supply chain.

After a series of cases of pneumonia in Wuhan, the capital city of Hubei province (China), the Chinese health authorities announced in January 2020 that a novel coronavirus, officially known as severe acute respiratory syndrome coronavirus (SARS-CoV)-2, was responsible for these cases.¹ SARS-CoV-2, the virus that causes the coronavirus disease (COVID-19), was not detected before the recent pandemic and has been known to be genetically similar to SARS-CoV.¹ The COVID-19 is transmitted mainly through contact with an infected individual, through droplets that are produced when the patient coughs or sneezes or through droplets from the saliva or nasal cavity.^1,2 To avoid transmission, it is very important to implement individual hygiene measures and especially the use of personal protective equipment (PPE). However, the lack of PPE and other key resources during the COVID-19 crisis has been a constant problem, leaving many health care professionals across the world unprotected.

Dealing with a pandemic, such as COVID-19, is an unprecedented situation in this modern globalized word, which has created extraordinary emergency that is particularly affecting the supply chain.³ The supply chain disruptions, in combination with the enormous needs for medical devices and protective health care material, have created the need of new initiatives and the use of emerging technologies such as three-dimensional printing (3DP) to come forward and support the health care professionals and supply chain.
