I'm aware that electrical stimulation of certain regions of the brain can insight various reactions, and I have recently seen work done with nano machines so small that they could not contain internal electrical components and so were piloted by magnets outside of the human body. Here is my query, what are your thoughts on the potential of piloting injected nanites to various regions of the brain and generating an external field which would cause the nanite to produce a small charge and stimulate regions of the brain through non-invasive means? I mean you still could theoretically run into the problem of getting magnetic fields through the resistant human skull, s…

Hello everyone, I did an internet search on these terms, but I want to make sure if I understood this properly. These are the biopsies I know 1. FNAC: You get a needle and aspirate cells 2. True cut (core) biopsy: You get a bigger needle and aspirate tissue rather than cells. 3. Incisional biopsy: You take a piece of the tissue of interest. Eg if there is an ulcer, you take a wedge shape part of it for histopathology. 4. Excisional biopsy: You take the whole tissue of interest. Eg removing whole lobe of thyroid, to look for follicular carcinoma. Questions 1. Did I understand these terms properly, my biggest confusion is incisional and excisiona…

I have a job working 10 hours at a warehouse and I am starving all the time. Which I am usually starving and have issues regulating my weight. When I dont eat enough I gain weight, which is irritating. I trying to figure out a good diet that has enough fat and protein where I dont get hungry but has enough roughage to maintain a healthy weight an regularity. Right now I am 115 pounds and 5,1. I trying to also gain some muscle which I dont seem to ever get, I just lose weight. How do you set up a decent diet plan?

Hello everyone, I thought I understood these terms, but got confused lately . My understanding Congenital- Present at birth Familial: Occuring in family or its members Hereditary: Transmitted or capable of being transmitted genetically from parent to offspring My questions 1. Ok congenital means disease it present at birth. In familial and hereditary also the abnormal genes are present at birth if so why don't their diseases present at birth, why do they manifest later in life? 2. Are all familial diseases hereditary? I really can't differentiate these. Any examples 3. Also aren't some congenital diseases, hereditary/familial? Any examples.…

Hi all, This is my first post here and I apologise I'm not much of a scientist, it is all fairly new to me. Just trying to get my head around how Thiamin becomes depleted in alcoholics and why it is the most supplemented of the vitamins when it comes to alcoholism and refeeding. I understand that Thiamin can become depleted in alcohol abuse since it is used in the metabolism of alcohol to convert Pyruvate to Acetyl-CoA. However, I believe that Vitamins B2, B3 and B5 are also somehow involved, so why is it that these vitamins don't also become depleted and require supplementation? Thanks!

Hy. I have used cortisone spray and injections for breathing problems with my nose and i got intoxicated after a year and a half of treatment. I lost my vitality, concentration power, it made me feel like an old person and I didn't recover back like I was before. I feel like i have no energy. Any opinions ? What should ?

All forum members - hello. My father recently died from lung cancer, don't know what type of cancer it was (a biopsy wasn't done - but he had a lung tumor and he had been a lifetime smoker for 46 years and painted cars for ~15 years with almost no protective equipment until ~13 years ago). He had almost no symptoms except severe back pain bron a spinal metastasis that greatly reduced his mobility (he complained of back pains since April but wasn't diagnosed properly until August). One day he came out of his bedroom bleeding from his nose and mouth, then collapsed and died within literally half a minute (all attempts of resuscitation failed). What possibly could ha…

I was introduced to this trick by a group of Spanish fruit pickers..... they invited us to their lodgings, and proceeded to grind sugar into the awful wine that we had been allocated. They poured the wine into a washing up bowl... added the sugar.... then started grinding it with an upturned glass. They told us it would get us drunk very quickly. Of course we naively laughed at them, saying that there is no additional fermentation, to increase the alcohol. Of course, after two glasses, they were laughing at us...... and we were all eating humble pie, with red cheeks and bleary eyes. In my life, I have never got drunk so quickly on such a small quantity of…

Does anybody know some good websites to learn Anatomy?

I have some questions regarding transgene types. What are episomal and integrative transgene and their differences? i am kind of confused. Please advise.

My mom was telling me a story how people in the healthcare industry in America were complaining because they were forced to have regular flu vaccinations and that the vaccination contained mercury. I have looked up the flu vaccination and it contains a substance called Thiomersal C9H9HgNaO2S which does indeed contain mercury. Is there any correlation between Thiomersal and mercury poisoning?

My body is one so when we eat the food, it does not mixed with my body. If eating mix with body, the death body is also cut as evolution, big bang, atomic bomb and black hole and they( black hole) are not the truth as they are not one. There are no black hole and no evolution as they are two.

Hello everyone, 1. I know 5% dextrose is isotonic outside body 2. Also 10% dextrose is hypertonic outside body 3. Also (5% dextrose + Normal saline) is also hypertonic However if we consider that once inside the body all dextrose gets metabolised by body, leaving only water. Then once inside the body these become 1.Hypotonic 2.Hypotonic 3. Isotonic Respectively. Then if a question comes about the tonicity of these solutions. Which one should I pick for example (5% dextrose + Normal saline) , I choose hypertonic or isotonic for that one. Thanks

Hello everyone, I was wondering what is the exact mechanism that rectal cancer gives a sense of incomplete evacuation after defecation (Tenesmus in scientific language). Also why is this is not present in colon cancer higher up eg in ascending colon cancer and only lower down like rectal cancer? EditReport + Q

Hello everyone, Let's take a woman with a breast lump for example and it is malignant. I know that stage 3 and 4 disease, eg advanced/metastatic disease treatment is chemotherapy/radiotherapy. Then after it is downgraded they surgically resect the lump (stage 1 and 2). While this makes sense my question is why don't they still remove the lump in advanced disease and then give chemotherapy/radiotherapy. Reason been if the tumour is not resected and you give chemotherapy, since the primary tumour is still there it would keep producing metastasis. Is the reason that surgical resection is too dangerous when metastasis present. Why is that? Thanks

Hey, I'm newly registered to this forum and honestly one of the main reasons I registered was to find a larger community for questions like the one I'm about to post. Hopefully someone can help me find a straight, accurate answer when I have trouble. That being said lately I've been seeing a lot of articles and arguments over the effectiveness of chemo therapy on cancer as opposed to other forms of treatment, usually natural or alternative methods. When I try to find straight statistical information on the success rates of chemotherapy and alternative treatments I usually end up looking at articles which are biased on one side and don't give actual statistic or perce…

Hello guys, I have few questions 1. I know MRI is best for soft tissue masses? What does soft tissues mean? I searched on the internet and the definition is vague. Is it simply all the tissue apart from bone in the body, which means its includes organs such as liver. Or is it all supporting tissue in the body such as connective tissue. 2. If soft tissue includes organs such as liver, pancreas. Does this mean since MRI is best for soft tissue masses, it is always the best investigation for liver pathologies when given the choice of performing CT or MRI. I know this depends on the disease and in some cases biopsy, USS may be better options but I'm just asking i…

Gentle men, go ahead, make your recommendations! Would prefer something I can find as an ebook though...

I saw coverage on the news channel about immortality being possible in the near future. I wanted to know if there are any experts on the forums that can elaborate on where we are and what still needs to be accomplished. I read an article that scientists have converted skin cells into stem cells then into neurons, which would be required to repair the brain as neurons die. I read that scientists have identified genes and have been able to trigger them to increase cellular respiration, which decreases with age. I read that telomeres degrade with cellular mitosis and will have to be repaired which they haven't been able to do yet. I read that molecular manufa…

What influence does temperature have on the electrical conduction system of the heart?

Hello guys i am looking for some help and guidance! Aminoacids are monomers and proteins are polymers. Explain how hydrolysis is used to break down proteins into aminoacids and how dehydration synthesis is used to build proteins from aminoacids. What is the relationship between enzymes and proteins? How enzymes work? When you break and egg the yolk is yellow but the rest is clear. If you fry the egg the clear area becomes white because the heat denaturizes the proteins. Provide other examples that may denaturize proteins. Why are large organisms (like horses, humans, etc.) made of small cells instead of a few large ones? Why is the small size important?What will happ…
