Grafting neurons grown from monkeys' own cells into their brains relieved the debilitating movement and depression symptoms associated with Parkinson's disease, researchers report.

Super-resolution RNA imaging in live cells

Published: Thu, 25 Feb 2021 11:33:08 EST

Ribonucleic acid (RNA) is key to various fundamental biological processes. It transfers genetic information, translates it into proteins or supports gene regulation. To achieve a more detailed understanding of the precise functions it performs, researchers have devised a new fluorescence imaging method which enables live-cell RNA imaging with unprecedented resolution.

What to do when a mammogram shows swollen lymph nodes in women just vaccinated for COVID

Published: Thu, 25 Feb 2021 08:25:11 EST

When women undergo breast imaging shortly after receiving a COVID-19 vaccine in the arm, their tests may show swollen lymph nodes in the armpit area. Radiologists say that this is usually a normal finding, and if there are no other concerns, no additional imaging tests are needed unless the lymph nodes remain swollen for more than six weeks after vaccination. The team has published an approach to help avoid delays in both vaccinations and breast cancer screening.

Measuring hemoglobin levels with AI microscope, microfluidic chips

Published: Tue, 23 Feb 2021 11:07:10 EST

A complete blood count can help ascertain the health of a patient and typically includes an estimate of the hemoglobin concentration, which can indicate several conditions, including anemia, polycythemia, and pulmonary fibrosis. Researchers describe a AI-powered imaging-based tool to estimate hemoglobin levels. The setup was developed in conjunction with a microfluidic chip and an AI-powered automated microscope that was designed for deriving the total as well as differential counts of blood cells.

Discovery of biomarker could help predict Alzheimer's years before symptoms emerge

A unique brain protein measured in the blood could be used to diagnose Alzheimer's disease decades before symptoms develop, according to new Edith Cowan University (ECU) research.

A new piece of the HIV infection puzzle explored

Researchers combine high-resolution imaging to observe the infection process in cell nuclei, opening the door for new therapeutics.

Damage to the heart found in more than half of COVID-19 patients discharged from hospital

Published: Wed, 17 Feb 2021 21:58:09 EST

Around 50 percent of patients who have been hospitalized with severe COVID-19 and who show raised levels of a protein called troponin have damage to their hearts. The injury was detected by magnetic resonance imaging (MRI) scans at least a month after discharge, according to new findings.

Radiological images confirm 'COVID-19 can cause the body to attack itself'

Published: Wed, 17 Feb 2021 15:11:16 EST

Muscle soreness and achy joints are common symptoms among COVID-19 patients. But for some people, symptoms are more severe, long lasting and even bizarre, including rheumatoid arthritis flares, autoimmune myositis or 'COVID toes.' A new has confirmed and illustrated the causes of these symptoms through radiological imaging.

Promising biomarkers to diagnose mild traumatic brain injury

Published: Tue, 16 Feb 2021 09:43:22 EST

Certain plasma microRNAs could serve as diagnostic biomarkers in mild traumatic brain injury, a new study shows. The biomarkers were discovered in an animal model and they were successfully used also to diagnose mild traumatic brain injury in a subgroup of patients.

AI can predict early death risk

Published: Tue, 09 Feb 2021 11:39:14 EST

Researchers have found that a computer algorithm developed using echocardiogram videos of the heart can predict mortality within a year. The algorithm -- an example of what is known as machine learning, or artificial intelligence (AI) -- outperformed other clinically used predictors, including pooled cohort equations and the Seattle Heart Failure score.
