Dental caries (tooth decay) is a common oral health condition that often causes significant pain and discomfort and may even lead to tooth loss. In severe and untreated cases, bacterial infection combined with the host’s immune response can cause bone resorption, or the breakdown of bone tissue in the tooth root. Moreover, traditional treatments for advanced dental caries, such as surgery, can result in bone defects that require complex bone grafting procedures.

Building on this knowledge, bone tissue engineering and dental tissue regeneration have gained the attention of researchers worldwide. Recent reports suggest that microRNAs (miRNAs)—small, non-coding ribonucleic acid sequences—play a key role in bone tissue regeneration. However, the underlying mechanisms and pathways regulated by miRNAs remain unclear.

To investigate the intrinsic processes involved in dental bone repair, a team of researchers led by Associate Professor Nobuyuki Kawashima, graduate student Ziniu Yu, and Professor Takashi Okiji from the Graduate School of Medical and Dental Sciences, Institute of Science Tokyo (Science Tokyo), Japan, has conducted a series of innovative experiments using human dental pulp stem cells (hDPSCs) and mice.

It’s spring, the birds are migrating and bird flu (H5N1) is rapidly evolving into the possibility of a human pandemic. Researchers from the University of Maryland School of Public Health have published a comprehensive review documenting research on bird flu in cats and calling for urgent surveillance of cats to help avoid human-to-human transmission.

The work is published in the journal Open Forum Infectious Diseases.

“The virus has evolved, and the way that it jumps between species—from birds to , and now between cows and cats, cats and humans—is very concerning. As summer approaches, we are anticipating cases on farms and in the wild to rise again,” says lead and senior author Dr. Kristen Coleman, assistant professor in UMD School of Public Health’s Department of Global, Environmental and Occupational Health and affiliate professor in UMD’s Department of Veterinary Medicine.

Long COVID can result in increased risk for a variety of serious health problems for young people, including those affecting the kidney, gut, and cardiovascular system, according to a group of new studies led by investigators at the Perelman School of Medicine at the University of Pennsylvania.

“While most public attention has focused on the acute phase of COVID-19, our findings reveal children face significant long-term health risks that clinicians need to monitor,” said senior author Yong Chen, Ph.D., a professor in the Department of Biostatistics and Epidemiology. The studies were conducted under the Researching COVID to Enhance Recovery (RECOVER) Initiative, a special project including more than two dozen health care institutions.

These medical centers pooled de-identified data from electronic health records dating back to the start of the COVID pandemic.

A new technique that uses soundwaves to separate materials for recycling could help prevent potentially harmful chemicals leaching into the environment.

Researchers at the University of Leicester have achieved a major milestone in recycling, advancing techniques to efficiently separate valuable catalyst materials and fluorinated (PFAS) from catalyst-coated membranes (CCMs). The articles are published in RSC Sustainability and Ultrasonic Sonochemistry.

This development addresses critical environmental challenges posed by PFAS—often referred to as “forever chemicals”—which are known to contaminate drinking water and have serious health implications. The Royal Society of Chemistry has urged government intervention to reduce PFAS levels in UK water supplies.

Thousands of patients will benefit from a new cancer jab for more than a dozen types of the disease, with the NHS the first in Europe to offer the new injection. The health service is rolling out an injectable form of immunotherapy, nivolumab, which means patients can receive their fortnightly or monthly treatment in 5 […]

Urban rats spread a deadly bacteria as they migrate within cities that can be the source of a potentially life-threatening disease in humans, according to a six-year study by Tufts University researchers and their collaborators that also discovered a novel technique for testing rat kidneys.

Leptospirosis is a disease caused by a type of bacteria often found in rats. It’s spread through their urine into soil, water, or elsewhere in the environment, where it becomes a source of infection and contamination for humans, dogs, and other species. While it’s prevalent worldwide, it’s more common in tropical regions, though a changing climate means it could become more common in colder regions as they warm.

In Boston, leptospirosis persists in local rat populations, and different strains of the bacteria move around the city as groups of rats migrate, according to a new study by Marieke Rosenbaum, M.P.H., D.V.M., assistant professor in the Department of Infectious Disease and Global Health at Cummings School of Veterinary Medicine at Tufts University, along with co-authors at Northern Arizona University (NAU), the United States Department of Agriculture (USDA), and the Centers for Disease Control and Prevention (CDC). In addition, their of a 2018 human leptospirosis case in Boston strongly suggests a link to rats as the source.

Managing complex medication schedules could soon become as simple as taking a single capsule each day. Engineers at the University of California San Diego have developed a capsule that can be packed with multiple medications and release them at designated times throughout the day.

The advance, published in Matter, could help improve and by eliminating the need for patients to remember taking multiple drugs or doses at various times each day. It could potentially reduce the risk of missed doses or accidental overdoses.

“We want to simplify medication management with a single that is smart enough to deliver the right drug at the right dose at the right time,” said study first author Amal Abbas, who recently earned her Ph.D. in chemical engineering at the UC San Diego Jacobs School of Engineering. She spearheaded this work with Joseph Wang, a professor in the Aiiso Yufeng Li Family Department of Chemical and Nano Engineering at UC San Diego.
