Antibody testing is key to understand immune response to SARS-CoV-2

While PCR testing has been used widely for COVID-19 diagnosis, it only provides information on who is currently infected. Antibody testing can tell who has been previously exposed to SARS-CoV-2, the virus that causes COVID-19, a metric that is essential for tracking spread across a population.

Study: Radioactive bone cement is a safer alternative for treating bone tumors

A radioactive bone cement that's injected into bone to provide support and local irradiation is proving to be a safer alternative to conventional radiation therapy for bone tumors, according to a study led by University of California, Irvine researchers.

3D bioprinting paves way for functional adult-sized tissues and organs

Research into 3D bioprinting has grown rapidly in recent years as scientists seek to re-create the structure and function of complex biological systems from human tissues to entire organs.

Virus transmission by dental tools and prevention by antiviral agent

Researchers at the University of Ljubljana have demonstrated how a virus can spread by droplets during ultrasonic scaler (USS) operation and how this spread can be mitigated by merely substituting the irrigant with clinical virucidal agents, namely sodium hypochlorite and EOW (Electrolyzed Oxidizing Water).

Detection of emerging SARS-CoV-2 variant in New York

Researchers at the California Institute of Technology in Pasadena have developed a software tool called "Variant Database" that has detected an emerging lineage of severe acute respiratory coronavirus 2 (SARS-CoV-2) isolates in New York.

New model to better predict risk of abdominal aortic aneurysms

An abdominal aortic aneurysm (AAA) can be a ticking time bomb if undiscovered in time. However, researchers at the University of Pittsburgh are developing a new model to better predict at-risk patients. And the tools they are using apply mechanical testing to the human body - which is itself a complex machine.

Researchers develop new algorithm to minimize errors in diagnosis

Researchers from the University of Copenhagen have developed an algorithm that can identify patients who may have been wrongly diagnosed.

UV light can be used to disinfect SARS-CoV-2 contaminated surfaces, says study

Using different UV exposure times and dosages, researchers showed that surfaces like glass, plastic, stainless steel, and N95 respirator material could be quickly and easily disinfected.

New tool tracks symptoms, assists healthcare providers to evaluate the effectiveness of treatment

Researchers from Regenstrief Institute and Indiana University School of Medicine have developed and validated a short questionnaire to help patients report symptoms and assist healthcare providers in assessing the severity of symptoms, and in monitoring and adjusting treatment accordingly.

Researchers create new cancer optotheranostics based on photosynthetic bacteria

Cancer is one of the most thought-provoking healthcare problems throughout the world. The development of therapeutic agents with highly selective anti-cancer activities is increasingly attractive due to the lack of tumor selectivity of conventional treatments.

Genetic testing technology wrongly detects the presence of very rare genetic variants

A technology that is widely used by commercial genetic testing companies is "extremely unreliable" in detecting very rare variants, meaning results suggesting individuals carry rare disease-causing genetic variants are usually wrong, according to new research published in the BMJ.

First wearable device for simultaneous monitoring of cardiovascular signals and biochemical levels

Engineers at the University of California San Diego have developed a soft, stretchy skin patch that can be worn on the neck to continuously track blood pressure and heart rate while measuring the wearer's levels of glucose as well as lactate, alcohol or caffeine.

$Big data can help assess risk prediction for osteoporosis, fractures$

Big data can help assess risk prediction for osteoporosis, fractures

Years of suffering and billions of euro in global health care costs, arising from osteoporosis-related bone fractures, could be eliminated using big data to target vulnerable patients, according to researchers at Lero, the Science Foundation Ireland Research Centre for Software.
