Hi. The typical sphygmomanometer has always been elusive for me to comprehend how it works, even with 'good' hydraulics knowledge. The inflating bladder and the presence of pressures in an 'arm' counteract somehow and the result is a valid reading, tossing in the mix the sthetoscope... I think. IF a manometer with the proper scale was hydraulically 'connected' to an artery, as tapping a existing/in-use intravenous needle on the patient arm; would such blood pressure be able to be permanently read/displayed/monitored in real time instead of the seemingly archaic process of pumping-ausculting-deflating periodically ? Would such way show the high and low heartbeat …

Focussing on the 10 hallmarks of cancer, more particularly in relation to the characteristic of evading immune destruction. This being that tumour cells evolved the trait to appear normal, therefore escape being forced to undergo apoptosis and being destroyed by various leukocytes. This is where immunotherapy steps in, adopting various methods to strengthen the immune system to recognise various cancers cells depending on the method used. As this technique seems quite promising, should this be the future focus?, and secondly what if a tumour is yet do evolve this characteristic? To me there is always going to be a need for a variety of techniques, I jus…

Just a quick question to anyone who might have the answers for me. Over many years I have been to a few different doctors and had some studies done, most of them involved hours worth of brain activity monitoring. During these tests, they would hook me up to a large amount of cathodes and have me perform different tasks, they would also ask me to close my eyes, open them, blink, move my eyes around, think of different things, and even watched me while I slept, they also used a bright light to shine in my eyes and flash at different speeds with my eyes both open & shut. After many visits and monitoring of my brain activity they brought me into a room with a …

I see the maze procedure indicated for catheter refractory atrial fibrillation, is it performed for ventricular arrhythmia too? From what I read poststabilisation management of VT/VF goes from radio-frequency ablation to ICD. Is it not somewhat palliative? No room for a more curative cardiothoracic approach in between? http://emedicine.medscape.com/article/159075-treatment#d9

http://www.hopkinsmedicine.org/neurology_neurosurgery/centers_clinics/restless-legs-syndrome/what-is-rls/causes.html Unexpectedly, Iron deficiency can cause restless leg syndrome. Supposedly iron may be needed by the neuromelanin cells in the substantial nigra to synthesise dopamine. How does this work? Is iron a co-factor for tyrosine hydroxylase or dopa decarboxylase? Also does this imply iron supplements may help extrapyramidal akathisia when using antipsychotics?

If so, are there any negative side effects from running too much? Does running increase one's oxygen uptake? Additionally, would free radical intake increase and thereby be harmful to your body?

How is the PPRF wired for vertical gaze, and how does this apply in Supranuclear Ophthalmoplegia? Can't find a good clear explanation for this piece of neuroanatomy, would really appreciate if someone can describe. Thank you!

Please expose/share techniques you know, experienced, heard of as more effective, clever, odd, complex, simple... them all.

A post coronary operation patient in recovering stage connected to a intravenous bag was advised to minimize as possible the ingestion of salty food. Does administering ClNa solution conflicts with the 'prescription' ? Or should the solution had been potassium chloride. ? Is it intra-venous or intra-arterial or does not matter ?

Hi,guys. I am here to ask for your opinion about the cells should be used to test for anti-obesity properties (in-vitro studies). From what i've found, there are two types of cell line that can be use for anti-obesity properties. They are 3T3 L1 cells and OP9 cells. Can somebody tell me which one of these cells is better?

Does alopecia affects only the head ? What about facial hair, rest of body ?

Michael Moore almost died. Got pneumonia was in ICU. http://www.salon.com/2016/02/10/michael_moore_could_have_died_last_week_trying_to_get_back_to_just_breathing_is_enough_of_a_burden/ How could some one this young get pneumonia? People that get pneumonia are old people and people with weaken immune system. And people in hospital or nursing home are more likely to get it The public normaily do not get pneumonia same with young people. How could this be? Could be that being overweight and a sedentary lifestyle have some thing to do with it? Or that he has other health problems?

https://www.sciencedaily.com/releases/2015/12/151216162426.htm Are these artificial colors the machine ads to image in real time scanning and viewing? Or is machine able to see real color. Like colored radiographic images, such as X-rays, mammograms and CT scans. I know when you look at say a kids books or high school books on the human body the artificial color is added to gray image after the scan to help visualize the image to the viewer.

It was not like this before!!! But now they say 1 in 4 people in US will get cancer and in the UK 1 in 3 will get cancer. They say if it continues in the UK in the future 1 in 2 people will get cancer. Why is cancer on the rise? What is causing this? Why was it not like this before say 50 years ago, 100 years ago or even 200 years ago?

Hello, I am a 31 year old mother. Currently pregnant. For YEARS... at least 7 years that I can date, I have become extremely sick when I drink any tap water. We are fine as long as I am using a reverse osmosis water filter or if I purchase any bottled water (never been sick 2ith any brands sold in stores). I recently put in a water filter/water dispenser in my ice maker of my fridge and thought it would be a safe thing to drink and now I am back to having severe stomach pain, diaharea and nausea with occasional vomit in along with sulfur burps. I have been tested in the past with h. Pylori etc... nothing is ever found. I do Not have any health problems what so ever…

i've done a hand full of things to remove my blackheads, like constant washing, popping, and using soup. what do i have to look for in products, to clean my blackheads

I remember reading a article in popular mechanics some time ago of some research and development in future medicine. -bacteria or viruses to fight cancer -Target drug delivery -nanobots bring chemotherapy drugs to the cancer target or performed surgery operation on clog arteries or heart surgery and other applications like fighting infectious disease so on. -lasers to fight cancer -lots of strong heat to fight cancer I remember reading some of this in popular mechanics but there not much info out there other than very advance information for medical students or doctors. I think nanobots hit wall, that It is true in the lab they have build small nanobots to…

Whats an advanced textbook on Nutritional science or sports nutrition for people who already have a solid understanding of biochemistry. Recommendations much appreciated!

Hi, I'm using the Qiagen miscript rtqPCR kit for small RNA quantification. I did a gel purification for RNA bands >40bp and those <40bp. When I then performed miscript with miRNA specific primers, I still had a strong signal ~24 ct for the >40bp gel fraction. However, melt curves and pcr products looked identical between >40bp and <40bp. Could it just be my gel run wasn't efficient in separating the bands? Seems hard to believe. Any insight would be helpful, thanks!

Does anyone think intracellular pH is an important physiological factor that regulates cellular function? The STAP papers have been retracted but perhaps intracellular pH may still have physiological relevance outside of stem reprogramming?

Wikipedia says that meldonium inhibits γ-butyrobetaine hydroxylase (IC50 = 62mcM), carnitine biosynthesis, and beta oxidation. How does this mechanistically link up with improved exercise tolerance in stable angina (and athletic performance)? Supposedly myocardial work is reduced decreased by the lack of beta oxidation feeding acetyl CoA into the Kreb's cycle, and this improves cardiac endurance?

I want to do a study of medical records... How do i get permision for it ? (I am not a doctor)

In 2007 I broke my femur and had a titanium rod put in (through my knee), held in place with titanium nails. I went to a "knee specialist" (yeah, I don't know, guess in Florida, which is where I happened to be at the time, they like to specialize in things like 'just knees', probably because there's so many people down there, they have to break the work load up; "Hey, if I take knee patients and you take back patients, that'll free us up for golf on Thursdays" ) recently to see if anything needed to be taken out, as I was starting to have a lot of pain in my knee where the 'nails' are. He basically told me "if you want to deal with the bills and hassle involved with s…

Sup people, I want to ask if anyone has experienced any growth after age of 19, I'm struggling with my height and I want to know all the possible choices I have to force some growth if possible! Share some of your stories here, or links, anything you have.. Reason to believe I could still grow? 1.I've been the same height since 14-15 (maybe gained 0.5 inches since) 2.I don't have a facial hair and I don't see it comming too soon 3.I have the build of a junior high kid If I won't be able to gain about 2 inches(atleast) I want to kill myself, I'm already researching on how to. So please no troll.
