#Lungs #health
The scan that takes less than 10 seconds and doesn’t need any intravenous dyes provides a complete picture of the chest cavity, creating a baseline image patients can keep for life. This approach also addresses critical gaps in preventive care, particularly for the growing number of patients experiencing lasting respiratory effects from COVID-19 and other environmental exposures. “Nearly six years after the pandemic’s start, we’re seeing increasing numbers of patients with lung scarring and fibrosis from COVID-19, especially those who get reinfected with respiratory viruses,” said Dr. Bharat. “The damage compounds with each infection. Early detection through comprehensive screening can help us intervene before these conditions progress to requiring transplantation.”

"age-based screening achieving 30% stage I detection would save $24.76 billion annually, far exceeding program costs"

Age-Based Screening for Lung Cancer Surveillance in the US
This cohort study examines the proportion, clinical characteristics, and survival of patients with lung cancer who meet or are excluded from the current US Preventive Services Task Force criteria.

The study identified a senoprotein, Gas6. Gas6 is a vitamin K dependent protein. The original study is paywalled, so I can't get details on whether Gas6 was carboxylated or not. Link to journal article: doi.org/10.1016/j.ce...

To test their findings, the researchers isolated a protein associated with aging in the aortas of mice, and injected it into young mice to observe the results. Animals treated with the protein had reduced physical performance, decreased grip strength, lower endurance, and lower balance and coordination compared to non-treated mice. They also had prominent markers of vascular aging.

Interesting comment on the video by Dr Younger in response to a question about whether commercially available naltrexone is racemic or not #naltrexone

Thanks for bringing up that issue! There has been a ton of misinformation on "regular" prescription naltrexone, even among experts. If you look it up on Google, it will tell you that naltrexone is a racemic mixture of l- and d- forms. Any many, if not most, papers do the same. They are all wrong. If you pull up the CoA for manufactured naltrexone, you will see it has a -192 degree optical rotation. All commercial naltrexone is levo only. Levo hits both opioid and TLR4 receptors (among other things), while dextro only hits the TLR4 receptor. I don't know how to fix the misinformation online because now AI is pulling its info from incorrect sources. So it is almost impossible to get to the right source unless someone already knows what they are doing (e.g., accessing the manufacturer CoA's). - Jarred Younger
