Ai used to detect COVID-19 pneumonia

Coronaviruses have 'spilled over' to human populations throughout history, causing respiratory illnesses, often associated with pneumonia. The severe acute respiratory syndrome (SARS), which emerged in 2002 in China, and the Middle East Respiratory Syndrome (MERS), which was first seen in Saudi Arabia in 2012, are similar to the current global pandemic spreading worldwide, the coronavirus disease (COVID-19).

Visualizing 3D microanatomy of human nipple to understand and fight breast cancer

Nipple-sparing mastectomy is gaining ground as a treatment or preventive measure for breast cancer, given the understandable desire among patients to preserve natural appearance as much as possible. But the precise risk of preserving the nipple is not known as the cancer can spread along mammary ducts and to the nipple.

Inhibiting the iron transport could halt tuberculosis

The bacteria that cause tuberculosis need iron to survive. Researchers at the University of Zurich have now solved the first detailed structure of the transport protein responsible for the iron supply.

Renal denervation effective in patients with untreated high blood pressure

Three months after undergoing renal denervation —a procedure that delivers energy to overactive nerves leading to the kidney to decrease their activity—patients with untreated high blood pressure had statistically significant reductions in average blood pressure over 24 hours compared with patients who underwent a sham procedure and experienced no major adverse effects, according to results from the SPYRAL-HTN OFF MED pivotal trial presented at the American College of Cardiology's Annual Scientific Session Together with World Congress of Cardiology.

Telemedicine surges, fueled by coronavirus fears and shift in payment rules

Lukas Kopacki, home from college after the coronavirus pandemic closed his campus, was feeling lousy for days with headaches, sore throat and difficulty breathing through his nose. But he worried that a trip to a doctor's office might make him sicker.

Researchers decode 3D architecture of SARS-CoV-2 main protease

Teams around the world are working hard to develop active substances against SARS-CoV-2. The structural analysis of functional proteins of the virus is very helpful for this goal. The function of a protein is closely related to its 3D architecture.

MILabs enhances preclinical diagnostic U-CT system for COVID-19 research

Based on recent scientific research, diagnostic X-ray CT is able to detect COVID-19, the disease caused by the novel coronavirus (SARS-CoV-2), in individuals with high clinical suspicion of the virus -- even in cases with negative initial DNA tests.

Lessons learned from three Singapore COVID-19 clusters

A study published in the journal The Lancet in March 2020 reports on three clusters of COVID-19 that happened in Singapore in February 2020. The first was because of a tour group, the second a company conference, and the third a church gathering.

Chest CT shows COVID-19 damage to the lungs

A new study presents peer-reviewed cases of COVID-19 in order to ensure that the disease is diagnosed as rapidly as possible, and thus help prevent an overwhelming spike in infections in any one place during the course of the current pandemic. Much interest has been shown in the possibility of using chest X-rays, and computed tomography (CT) scans to screen for and diagnose patients with this illness, whether suspected or confirmed.

Alzheimer's and its helper protein

It is commonly observed that the brain in patients with Alzheimer's disease (AD) often contains fibrils of tau protein, which build up within the brain neurons to interrupt proper communication between them. However, it is far from clear what these deposits mean and how they form.
