New nano-optic endoscopes offer high-resolution imaging at extended depth of focus

The diagnosis of diseases based in internal organs often relies on biopsy samples collected from affected regions. But collecting such samples is highly error-prone due to the inability of current endoscopic imaging techniques to accurately visualize sites of disease. The conventional optical elements in catheters used to access hard-to-reach areas of the body, such as […]

More studies needed to validate link between air pollution and gynecologic health, say researchers

While initial studies suggest a potential relationship between air pollution and both infertility and menstrual irregularity, researchers from Boston University School of Medicine (BUSM) believe more studies are needed to validate these findings in other populations. Air pollution is widely known to affect human cardiopulmonary health, but only recently has research turned to understand the […]

What is a blood gas test?

Purpose Procedure Risks Additional testing Understanding the results pH and PaO2 Takeaway A blood gas test is also called an arterial blood gas test or a blood gas analysis. It measures oxygen and carbon dioxide levels in the blood. The test can also show blood pH levels and lung function. Doctors often use blood gas […]
