One of the questions I'm reviewing asks "which of the following amino acids can the oxygen group (which in the passage is part of an antitumor agent that can be a H-bond acceptor) interact with?" and the choices were: aspartate, cysteine, tyrosine, and lysine. In the explanation, it says only lysine can be a H-bond donor but doesn't that also apply to tyrosine?
I understand that eating disorders can occur from cptsd, abuse, neglect etc.
What about physiological issues? Nutritional absorption etc.
I have enormous difficulty putting on weight. I am an adult male. I weigh under 100lbs.
I eat 500-600 calories a day over RDI. I am in my 30's and weigh as much as a 13yo.
Can this be caused by CPTSD? Can emotional neglect affect how my body absorbs calories?
Mini rant time. I’m so drained from constantly having to convince my family and some of my friends that what I’m going through is a physiological issue that I don’t have control over. I feel like I’m constantly on trial trying to prove myself and my symptoms. They do validate some of my symptoms like when I wake up out of dead sleep with a 150 bpm HR, but they always manage to slip in a comment about how I should go see a psychiatrist/work through my anxiety.
I will admit I 100% have anxiety from experiencing all of these extreme symptoms. I’ve recently started getting nervous about being out & about or in a car and getting symptoms which is definitely psychological. But it all stems from my very real symptoms. It doesn’t help that the first cardiologist I went to before I was diagnosed told me I was too young to have issues and laughed in my face when I explained my symptoms & told me to throw away my Apple Watch. Conveniently my mom was in the room for that.
I empathize for anyone going through something similar & owe this subreddit most of my sanity for validating how I feel 💜
This manuscript presented a brain-computer interface (STM32 and ADS1299) with an embedded board with sensors to monitor the subject's state and environment. To reduce power consumption and device size, we used sensors made in Micro-Electro-Mechanical Systems technology (MEMS)-a gyroscope, accelerometer, and environmental monitoring sensors: CO2, temperature, humidity, ambient sound, and pulse and blood oxygen saturation. Data from the device is transmitted using TCP-PI (UART by Bluetooth) protocol to a computer or mobile device. Open-source https://github.com/Ildaron/ironbci
So I've been dealing with a lot of changes lately. My dad committed suicide and I've had to let go of things in the past in a big major way. I'm planning to get married soon too. I find that I'm bedridden lately due to the emotional stress and heartbreaks.
I asked how my physiological state was and I got Death.
I asked if I was sick and got Knight of Cups.
Then I did a three card spread asking what's going on with my body and I got... Ten of Pentacles (family/ buildup of something) Ace of Wands (deciding) Eight of Cups (to do something better with one's life)
Am I stressed out emotionally and physically because I am being distant or because they are being distant? Maybe it's both.
I think my emotional state is affecting my heath. Any thoughts on this?
Edit: I asked further questions...
Will a doctor help me heal? Seven of Pentacles (hard work with little reward)
Will a change in diet help me heal? Page of wands reversed (it's not what you're looking for)
What about exercise? The Emperor (you have to do that anyway)
What about sleep? The World (fulfilled potential, that's what will help ultimately)
36m, I’ve suffered from major depressive disorder since my early teenage years. I’ve seen a number of extremely empathetic and well versed therapists in that time and while it can feel validating to speak with a professional that can intellectually understand some of my struggles, I was going to therapy with the understanding that this was a medical intervention to cure me of my depression so that I could lead a ‘normal’ life with ‘normal’ life difficulties but general happiness or at least contentment.
Looking back, I feel like it was never made clear to me that the condition I suffered from wasn’t really (or entirely) psychological in nature but rather a neurological/medical condition due in part to chemical deficits in my brain. And that talking about my neurological condition was NEVER going to solve the problem. In the same way that talking about diabetes doesn’t cure diabetes.
Now, while my depression has been extremely treatment resistant over the past two decades, I finally found a medication (the MAOI Parnate) that has finally provided me with some semblance of relief. But this is sort of my point, medication is a medical intervention. A chemical intervention for a chronic physiological condition. And this medication has done more for me in 3 months than 20+ years of therapy. In hindsight, the concept of talking someone through a disease of the brain seems especially asinine to me.
Furthermore, I feel like therapists in general fail to make the distinction to their clients, and that the relief they can expect to experience with intensive talk therapy is proportional to their affliction. Traumatic breakup? Yes, therapy can be extremely beneficial. Grief? Yes. Anger issues? Yes. Trouble making friends, maintaining relationships? Yes. Chemically based chronic depressive disorder? Absolutely not.
It’s not that they can’t empathize or commiserate with you (which can feel helpful), it’s that intensive talk therapy with no relief of neurological symptoms can feel like yet another failure in the quest to rid yourself of severe depression. In my experience, this can ultimately make things worse. I just wish therapists in general would be more honest with their patients (and themselves) when it comes to treatment expectations and outcomes for people with circumstantial depression vs people with chemical deficits in their brain. Sometimes I’m not even sure that they themselves are able to make the distinction. Or even worse...that some know and tell
... keep reading on reddit ➡Technically its side chain is pka 6.0 so its mainly uncharged but most of the tables/ resources I look at give it the +1 and group it with lysine and arginine. Seems like something that it depends on who you ask. Has anyone ran into a question in AAMC content that would clarify their view on histidine?
Hello,
When there is portal hypertension, blood flows "backwards" to others veins like the rectal veins, splenic veins, gastric veins, oesophagial veins or even the splenorenal vein.
I would like to know if these anastomosis actually exist when everything is ok, or does these shunts/anastomosis created when we have this hypertension.
Thank you in advance !
Sorry if this is too long, but if you take the time to read it, thank you.
Don’t feel the need to go too into detail, but basically a few years ago the love of my life broke up with me after two years. She did it in a completely uncharacteristic manner and only 5 days after a vacation together. This absolutely devastated me and threw me in a vile spin of confusion, sadness, regret, anger, hatred and emptiness. We were the best of friends and had countless memories together. To be clear, I wasn’t the clingy one either.
The feelings I had at the time of the breakup were much stronger than I have now, of course, but it seems like the only way my mind can get a rational grasp of the situation is that this girl just vanished from existence or something, and was just taken away somewhere else.
It’s to the point where some nights I will have dreams about her and the memories we shared with each other. Honestly kinda feels like cobb and mal from inception, where I can feel her touch and breath and everything in my dreams, which sometimes I hate waking up from. It’s gotten to the point now where I want to stay in those dreams with her cause when I wake up I’ll usually only remember small parts of the dream.
I’m not dysfunctional or something. I work in construction and (arguably) live a pretty healthy lifestyle, besides the fact that I don’t date. I have passions, hobbies etc. But these feelings and memories of this girl get recycled through these dreams and thoughts, they just make me wanna cry so bad sometimes. (which I sometimes do).
tl;dr: Sorry this is so long, but my question is, am I truly suffering from something?
In the Klein Organic Chemistry 2nd edition, it says that Tollen's Reagent is used to detect the presence of BOTH aldose and ketose (any reducing sugar), because ketose will automatically tautomerize to aldose and be oxidized by Ag+. However, I see quite a few MCAT-related references saying that Tollen's reagent is only used to detect aldose. In addition, the body also has a separate epithelial transporter and liver metabolism pathway for fructose. It makes me wonder if ketose tautomerize to aldose under normal physiological condition? And what about under the in vitro chemical conditions under Tollen's Reagent? Thanks!
