Vaping CBD causes more severe lung damage than vaping nicotine, new study shows

Vaping cannabidiol (CBD), a compound found in marijuana, leads to more severe lung damage than vaping nicotine, according to a study by researchers at Roswell Park Comprehensive Cancer Center. Until now, research on the health effects of vaping, or using e-cigarettes, has focused almost exclusively on vaping nicotine as opposed to CBD. Previous research has documented the effects of smoking cannabis, but the effects of vaping cannabinoids such as CBD were not previously known.

Research team delivers a new first in heart failure treatment using cell therapy

Physician-scientists at The Texas Heart Institute announced today the results of the largest cell therapy trial to date in patients with chronic heart failure due to low ejection fraction. The therapy benefited patients by improving the heart’s pumping ability, as measured by ejection fraction, and reducing the risk of heart attack or stroke, especially in patients who have high levels of inflammation. Also, a strong signal was found in the reduction of cardiovascular death in patients treated with cells. The findings are published in the Journal of the American College of Cardiology.

Researchers develop new material to replace extracted human teeth for dental research

Extracted human teeth have long been used in conducting dental research, such as evaluating dental ceramic materials as a crown restoration on tooth. It is an inexpensive and straightforward process that simulates clinical situations. However, the collection and use of extracted human teeth is becoming increasingly difficult given the concerns about COVID-19, size-standardization issues, and also time constraints. All these factors have prompted a need for dentine analog materials that could potentially substitute extracted human teeth in laboratory-based mechanical and fatigue tests.

New method for image reconstruction in electrical impedance tomography

Recently, a team led by Prof. DU Jiangfeng from the Key Laboratory of Microscale Magnetic Resonance of Chinese Academy of Sciences (CAS) developed a new method for deep electrical impedance tomography reconstruction without training, which paved a new way for applying electrical impedance tomography technology in determining lesion tissue specificity. This work was published in IEEE Transactions on Pattern Analysis and Machine Intelligence.
