Question: what are if any the differences in brain activity between adults and children when using imagination.

I'm an organ donor and have been for many years now. As have all my friends and family. Registering as an organ donor, as far as I can tell, seems to be the done thing now - especially as policy change across the world gradually sees more national 'opt-out' organ donation models. I assumed shrinking transplant waiting lists. But then I came across this article: http://careers.imhgroup.net/link-self-driving-cars-organ-donation/ While there are apparently more donors, according to this article there may well be fewer actual donations thanks to medical advancements. I guess my question is WHAT IS THE ANSWER? WHAT WILL BECOME OF US? I'm just c…

Say you're a pediatrician. You come across a patient's parents who express concern for vaccine-induced autism and it depends upon you to assuage their fears. An example argument I've come across is that cases of mitochondrial dysfunction are potential hazards when a post-vaccine fever presents itself, leading to poor metabolism in the brain, resulting in permanent brain damage and autism-like symptoms. If you attempt to explain the counter-science (not to mention the essentially nonexistent correlation), it doesn't matter. How do you approach parents who are 100% obstinate to scientific research? How do you approach ANYBODY who is unwilling to read any further than a c…

I've heard and read from various sources that vaping was found to contain the chemical diacetyl which gives the vaping liquid its delicious buttery flavor. I've heard that this is linked to a condition known as "popcorn lung". This may be an old question that is either debunked or confirmed, but I just wanted to know what the smart folks here thought about it. Does using vaporizers cause a real threat to human health/life? Thanks.

Hi all Does anyone know if klonopin and motrin use the same pathway? I took motrin after a wisdom tooth extraction. I've taken a small dose of klonopin for sleep many years. I think my klonopin was decreased by motrin

Hi! my supervisor wants me to use exosomes in our model and I am trying to follow th methodof Nat. Protocols El-Andaloussi et al 2012 and Alvarez-Erviti Nat Biotech 2011 but I am not getting any silencing in the brain and I have just seen these comments in you tube and in this blog talking about fraud and saying that this papers should be retracted! who should I trust? does anybody know other protocol for brain delivery of siRNAs using exosomes? I am quite desperate! any advice would be greatly appreciated! http://metamodern.com/2011/03/22/across-the-blood-brain-barrier-with-exosomes/ Cheers

You always hear about the health benefits of exercise, but it seems to me that when people say exercise they usually mean something like running, cycling or swimming. I'm wondering is there any evidence for any health benefits to weightlifting? And I don't mean muscle gain or fat loss, I mean are there any benefits beyond that that you don't get through running?

I have been told that gamma beams cannot work with ball lenses, but X-rays, and other electromagnetic radiation, I am unsure about. how much can gamma knife beams be collimated without using ball lenses. What would be the smallest cubic area in the brain you could ionize, without gamma beams passing through a ball lens. Can you tell me the effects for X-Rays, and other electromagnetic radiation, if they can pass through a ball lens or not. If you can ionize neurons at micron scales you can stop the spread of Parkinson's disease throughout the brain. It would be tricky, and complex, but not impossible. You could probably erase memories specifically in an animal also,…

I believe one of the terminating ILLNESS for Human Beings particularly in their OLD AGE is the very Popular COLD and its Manifestations ! I understand COLD is a Virus ! Don't we require to channelize all our energy to FIGHT THIS VIRUS with concentrated Research and Scientific Efforts ! Something like a VACCINE or CURE to Remove this Virus from Earth or at least from Human Beings ! Just Brainstorming here !

If you start feeling that your are on the edge doing normal activities and that small inconsistencies in life set you off, you may have been infected with a form of herpes/shingles. This may have been spread to you unintentionally or intentionally through food or being around people who do not cough into something. Shingles can mimic the symptoms of psychosis which could make it very difficult to treat.

What is the motor threshold when using transcranial magnetic stimulation, in Tesla?

Why cant RBCs diffuse across other cell membrane just like other cells ? This question has been bugging me for days and I've scratched my head way too much🙈😹 . I read about it and about the interstitial fluid in the tissues could be the reason why they don't diffuse in tissue cell membrane.. but I'm not just satisfied so can anyone please help,?

I'm interested in the author's intent in the conclusion of this paper in the last bolded line. Are they saying 'yes' optimism is good and 'yes' it is not good, or 'yes' it is good for immunity?

For those who know, we know that our subconscious get affected oftenly by the outer environment, also if our consciousness is moulded by what our subconscious mind feeds upon, then it could simply mean that we are all prisoner of influences. What do you say?

Not in terms of body organs starting to go bad, illnesses, cancer and diseases so on, because that is more complicated. But why people look old like gray hair, thin hair, skin and body looks really old. Yes I know rich people see cosmetic doctors and pay lots of money and may look 10 years younger!! But still this not holy grail, I don't see rich people, movie stars and pop starts looking like they are in their 20's!!! Yes they see cosmetic doctors and pay money but at the most they look 10 years younger not some one in their 20's So what really makes some one look old? Why no cream, pill, laser surgery or some other thing to make 60's and 70's look like 20's? …

I will soon be assessing brain glutathione using MRS, but will take bloods for analysis of redox markers in the circulation. Although important on their own, the blood measures of oxidative stress and markers of neuroprotection that I will measure should be compared to what is going on in the brain. Basically, I need to know if the two measures are comparable, since I cannot find any evidence in the literature.

I'm having difficulty understanding the rise in glucose starting about 30 minutes after a meal that occurs in type 1 diabetics. Obviously enough, they lack insulin to cope with postprandial glucose. However, everything I read seems to indicate that gastric emptying for a typical meal in anyone doesn't start until about an hour after the meal, reaches 50% about 2-3 hours afterwards, and isn't finished until 4-5 afterwards. Even ignoring that type 1s might exhibit gastroparesis which would slow down emptying even more, it seems contrary to what a typical graphs show for type 1 postprandial glucose concentrations. I thought initially it was because the studies were just …

If during surgery, a small portion of an organ -say liver- is severed-off and a minute later is placed back nearly as it was but not perfectly aligned to its original position; will it re-attach and function, heal and work properly or the portion will die/rot/cause trouble ?

Does more bodyweight affect it and, if so, what is the mechanism by which it raises it? Can drugs like antidepressants raise it and, if so, how?

Hello everyone For my paper this year, consider a 2x2-table with following information: 37 premature babies needed postnatal ventilation. 168 didn't. 145 babies born at term needed postnatal ventilation. 2 819 didn't. A Chi²-test conform Pearson (SPSS) has indicated a significant difference in the distribution of the need for ventilation in both subsamples (at term v. premature). Is it more interesting to report an odds ratio of 4.28, or to report a frequency of 18.05 % in premature babies v. a frequency of 4.89 % in babies born at term? Thanks! F

Hello everyone Again for my paper, I was wondering for a specific variable, if it would be more interesting to report mean or median: The duration of pregnancy is not distributed conform the Gauss normal distribution (significant Kolmogorov-Smirnov test, p < 0.001). When comparing the durations between 2 sample sizes (they do differ significantly when it comes to pregnancy duration, p = 0.002), is it then more interesting to mention mean (SD) or median duration? So do I say the mean or median durations do significantly differ? Or doesn't this matter? Another problem: apgar score measured at 1 minute v. at 5 minutes postnatal: they are both ordinal var…

Does anybody know the difference and the pros and cons between the two treatments? My 18 year-old cousin has a big acne problem and the post-acne scars which has made him go through a variety of treatments and medicine, some at the dermatologists and some at home using stuff from indigenous knowledge recommended by people with the same experience. Lately he's been going to a dermatologist who's been giving him the laser treatment. He's done it twice but now notice that it's getting too expensive each time. He once used to go to a dermatologist who gave him the Iontophoresis (using electric current and vitamins) which was a lot more economical but he stopped it to try some…

A randomized, double-blind, crossover study of the effects of long-term treatment with Salmeterol on asthma control was carried out (Wilding P et al. BMJ 1997; 314: 1441-1446). 101 subjects with mild or moderate asthma taking at least 200 micrograms twice daily of beclomethasone dipropionate or buclesonide were included. Patients continued to take this medication but were randomized to receive additionally either Salmeterol 50 micrograms twice daily or placebo for a six month period, with a one month washout between the two. The primary outcomes of the trial were a reduction in inhaled steroid use, exacerbations of asthma and the use of oral steroids. Select all of the fo…

Hello all! After seeing multiple doctors over 3 years, I was finally diagnosed with both Fibromyalgia and Peripheral Neuropathy. It has been nearly 5 more years and I now am completely unable to work. Despite the multiple meds, I am still in terrible pain and have no energy. It is a miracle when I am occasionally able to do housework or grocery shop. Most days I find that I don't have much of an appetite and I know that I'm not getting the vitamins and minerals that may help me feel a little better. I don't want to waste time and money on ones that I don't need or that are not metabolized correctly. Anyone out there that can help me?? Thanks in advance!!
