A Smartphone’s Camera and Flash Could Help People Measure Blood Oxygen Levels at Home

September 19, 2022

Monitoring the amount of oxygen in your blood could one day be done using your smartphone, shows a study by the University of California San Diego and University of Washington. This could help patients keep an eye on conditions that make it harder to absorb oxygen, such as asthma and…

Engineering a Solution to a Skin-Deep Problem of Blood Oxygen Measurements

October 11, 2022

Blood oxygen monitoring is one of the main methods to determine if COVID-19 patients need immediate medical attention, but the devices used for these measurements can be less accurate on darker skin tones. UC San Diego nanoengineers are engineering a solution to improve accuracy on all skin tones.

Andeans with Altitude Sickness Produce Massive Amounts of Red Blood Cells

November 7, 2016

…of California San Diego School of Medicine studied red blood cells derived from representatives of both groups living in the Andes Mountains. The study reveals that high-altitude, low-oxygen dwellers prone to chronic mountain sickness produce massive amounts of red blood cells thanks to overproduction of the enzyme SENP1.

Can Current Smartphone Technology Tell You When a Pandemic Might Come Calling?

February 9, 2021

UC San Diego researchers find that an optical tool already embedded in many smartphones can accurately diagnose blood-oxygen levels and help monitor respiratory disease in patients, particularly when they are quarantined at home.

Genetic Adaptation Keeps Ethiopians Heart-Healthy Despite High Altitudes

August 3, 2015

…human adaptations to low oxygen, a condition known as hypoxia. One factor that may enable Ethiopians to tolerate high altitudes and hypoxia is the endothelin receptor type B (EDNRB) gene. Researchers at University of California, San Diego School of Medicine now find that mice with lower-than-normal levels of EDNRB protein…

Three Generations of UC San Diego Physicists Plumb the Microvasculature of the Mammalian Brain

June 11, 2013

Blood vessels within a sensory area of the mammalian brain loop and connect in unexpected ways, a new map created by a team that includes three generations of UC San Diego physicists has revealed.

Scientists Investigate the Role of the ‘Silent Killer’ Inside Deep-Diving Animals

May 14, 2014

With its imperceptible features, carbon monoxide is widely known as the “silent killer” due to its risks at lethal concentrations. Far less known is that carbon monoxide is produced naturally in small quantities in humans and animals, and in recent years medical researchers have evaluated the gas as a treatment…

Targeting Molecular Pathway that Causes Pulmonary Arterial Hypertension

May 6, 2022

UC San Diego researchers describe the underlying signaling pathway that results in pulmonary arterial hypertension and a novel monoclonal antibody therapy that blocks the abnormal blood vessel formation characterizing the disease.

Low Oxygen Levels Could Temporarily Blind Marine Invertebrates

May 8, 2019

Scientists at Scripps Institution of Oceanography at the University of California San Diego have found that low oxygen levels in seawater could blind some marine invertebrates.

Exercised Over Nothing: Masks Don’t Impair Lung Function During Physical Activity

November 16, 2020

A team of American and Canadian researchers report that while they may feel uncomfortable, there is little empirical evidence that wearing a face mask significantly diminishes lung function, even when worn during heavy exercise.
