Anesthesia’s effect on consciousness solved, settling century-old scientific debate — ScienceDaily

Surgery would be inconceivable without general anesthesia, so it may come as a surprise that despite its 175-year history of medical use, doctors and scientists have been unable to explain how anesthetics temporarily render patients unconscious. A new study from Scripps Research published Thursday evening in the Proceedings of the National Academies of Sciences (PNAS) solves this […]

Scientists find brain center that ‘profoundly’ shuts down pain — ScienceDaily

A Duke University research team has found a small area of the brain in mice that can profoundly control the animals’ sense of pain. Somewhat unexpectedly, this brain center turns pain off, not on. It’s also located in an area where few people would have thought to look for an anti-pain center, the amygdala, which […]

Vitamin D levels appear to play role in COVID-19 mortality rates: Patients with severe deficiency are twice as likely to experience major complications — ScienceDaily

After studying global data from the novel coronavirus (COVID-19) pandemic, researchers have discovered a strong correlation between severe vitamin D deficiency and mortality rates. Led by Northwestern University, the research team conducted a statistical analysis of data from hospitals and clinics across China, France, Germany, Italy, Iran, South Korea, Spain, Switzerland, the United Kingdom (UK) […]

‘Single pixel’ vision in fish helps scientists understand how humans can spot tiny details — ScienceDaily

Recently discovered ‘single-pixel vision’ in fish could help researchers understand how humans are able to spot tiny details in their environment — like stars in the sky. In a paper published this week, researchers at the University of Sussex found that zebrafish are able to use a single photoreceptor to spot their tiny prey. This […]

Two drugs show promise against COVID-19: Both drugs are FDA-approved for other illnesses — ScienceDaily

Korean researchers have screened 48 FDA-approved drugs against SARS-CoV-2, and found that two, that are already FDA-approved for other illnesses, seem promising. The FDA approval for other uses would greatly reduce the time needed to gain FDA approval of use in COVID-19. The research is published in Antimicrobial Agents and Chemotherapy, a journal of the American […]

Taking inventory of which drugs the world is using to treat COVID-19: Researchers create database to categorize off-label use and look for promising leads — ScienceDaily

With doctors and researchers around the world searching for effective treatments for COVID-19, many drugs approved to treat other diseases are being used in hopes that they’ll be effective against the virus, a use that’s known as “off-label.” New research from the Perelman School of Medicine at the University of Pennsylvania catalogued every use documented […]

Researchers urge halt in prescribing hydroxycholoroquine for COVID-19 — ScienceDaily

The sacred oath taken by physicians during graduation from medical school to “First do no harm,” the first words of the Hippocratic Oath, provides a strong impetus for a commentary just published in The American Journal of Medicine. Researchers from Florida Atlantic University’s Schmidt College of Medicine and collaborators from the University of Wisconsin School of […]

New pill could prevent anaphylaxis in people with food, drug allergies: Drug would be the first known treatment to prevent anaphylaxis — ScienceDaily

For someone with a food or drug allergy, the risk of life-threatening anaphylactic shock lurks around every corner. A new Northwestern Medicine study shows there might be a pill that can be taken proactively to prevent mild to life-threatening anaphylaxis, no matter the cause. Anaphylaxis is a severe, potentially life-threatening systemic allergic reaction that can […]

3D Printing in Healthcare: Technology Trends

3D printing, also known as additive manufacturing, is the process of joining materials to make objects from 3D model data, typically created by building one layer upon the previous layer. This contrasts with subtractive manufacturing, in which parts of a block of material are selectively removed. 3D printing is used across a range of sectors, […]
