If you’re working on a budget like I was when starting out on my own, I recommend your first purchase to be a bed frame. You can use Ceaigslist / FB marketplace to find some really cheap used options. From there, you can start buying (used) furniture that matches the bed frame. Personally, I needed a nightstand immediately after the bed frame because I wanted to put my glasses somewhere.
Grapefruit interacts with specific metabolic pathways in the liver. Most medications are broken down by the liver. That’s just how the body works, unfortunately
Strangely, was never an issue for me. I usually wear thick rimmed plastic ones, the metal in the screws was never pulled into the machine.
But, if I was getting an MRI of my head I would take them off. Mostly because they didn’t fit. But they could also distort the images or, worst case scenario, absorb the radio waves and heat up.
Ramp-down isn’t really possible. The idea behind the super cooled coil is that once activated, it takes almost zero energy to maintain the (very strong, like 300,000x more than Earth’s) magnetic field. A super cooled coil can keep an electric current for a very, very long time. The magnet is ALWAYS ON, and the door into the room has a big warning about it. All employees in the same building as the MRI should be trained to Read The Fucking Sign. Cop should have, too.
It would take a huge amount of force to pry the gun free. I would argue the risk of prying the gun free and it discharging is much worse than the cost to reactivate the magnet. If the gun was hot, I don’t know if they could have even cleared the magazine at that point. The bolt or magazine may have been stuck in place.
During the very early days of COVID I walked into the magnet room with a homemade reusable mask. It had a twist tie in the nose to keep it from fogging my glasses. I was 10 feet away from the magnet when I felt it start to be pulled free from my face. I’ve never noped out of a room more quickly in my life…
I love these stories so much. Anytime a metal object is sucked into an MRI, they experience “projectile acceleration”. Since the strength of magnetic pull increases the closer an object gets, objects will accelerate rapidly. I’d argue a live rifle stuck to the MRI is an emergency. The gun could have discharged. Then I’d sue the hell outta the city.
I worked in MRI for many years. There’s a big, red button behind a plexiglass access window that releases all the liquid helium which keeps the superconductivity of the big-ass magnetic coil. It’s called a quench, it’s loud, dangerous, and only to be used in life-or-death emergencies, e.g. person is trapped between an oxygen tank and the MRI. Pressing the button kills the MRI and it can cost millions of dollars to reactivate it.
I worked with these things for almost 10 years. The urge never abates, we just learn to manage it.
I studied parts of the basal ganglia, part of the dopaminergic circuits of motor control. I’m not sure if it’s a poorly written (news) article or the scientist was overstating his position - I don’t know any neuroscientists who think dopamine is “sprayed” across the brain.
Edit: The paper is a breakthrough because it’s reporting the first-ever direct imaging of dopamine signaling. But the news article mischaracterizes it.
