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…

Lung cancer or lung disease seems to be hardest to cure or treat. In chronic bronchitis, the airways that carry air to the lungs (bronchial tubes) get inflamed and make a lot of mucus. This can narrow or block the airways, making it hard for you to breathe. Emphysema. In a healthy person, the tiny air sacs in the lungs are like balloons. As you breathe in and out, they get bigger and smaller to move air through your lungs. But with emphysema, these air sacs are damaged and lose their stretch. Less air gets in and out of the lungs, which makes you feel short of breath. Chronic obstructive pulmonary disease (COPD) in COPD is a lung disease that makes it hard to …

If ketones are showing in urine, does this mean protein, not fat is being metabolized? What is the reason ketones would be present if there was adequate fat intake? Carbs were low in the diet at the time, but I'm trying to make sense of the protein vs. fat scenario. Sugar was not an issue in the urine at the time of high ketones. I was told by a physician that most teenagers will test positive with ketones after not much food intake and after hours of exertion from sports, but I was concerned about a toddler. Is this true?

Hi everyone, I just finished med school last year and I want to continue my studies. I'm very interested in the field of medical devices and prosthetics, I would love to be able to design and create them but I don't know how could I fuse my medical degree with that nor where could I study that. Could someone guide me please? Thank you

I searched the actual meaning of wafi/cip.. but I could not find it.any one have any idea?

Usually in medical laboratories, the hormones are injected into the cells of human body using syringes. Does anyone knows any other latest technology delivering enzymes into our body cells? Does it necessary to deliver at high speed or at minimum speed is enough? Other than syringes what are the other ways doctors use?

Much has been said about the Germanwings co-pilot who coaxed the pilot out of the cockpit, so he could lock the door and crash the plane. What about his mental state? How often does a pilot, or bus driver, intentionally kill themselves AND their passengers? It seems like a severe hatred of other people, including himself. News report stated Andreas told his girl friend (or x girl friend?) that he was going to do something that will be remembered that will "change the system". What can this possibly mean? http://www.nytimes.com/2015/03/31/world/europe/germanwings-copilot-andreas-lubitz.html?_r=0

Hello everybody and everyone... A December 2014 report about thyroid cancer saw 86 cases among 298,577 young people under 18 in the Fukushima prefecture. Lacking a reference report for Japanese people, I compared it with a French study http://www.invs.sante.fr/fr/content/download/7760/52112/version/1/file/bilan_cancer_thyroide.pdfpages 31-32 that saw 224 cases among 11 million French children under 14, that would extrapolate proportionally to 26ppm up to 18 years, or 8 expected cases amont 298,577 people. That discrepancy would be very significant, but The criteria of cancer may differ The populations differ genetically and culturally If I compare now with…
