I was living in England when the world-wide hysteria over the 'date rape' drug GBH first seized hold of public consciousness. Officials in the British government were alarmed that their laws did not permit them at the time to prohibit the manufacturing, sale, distribution, and use of the drug, so being naughty, I thought I would buy some and try it. I found it really salty -- so salty in fact that I couldn't understand how anyone could possibly slip it into someone's drink without the person noticing it, unless it were tomato juice already spiced with Worcestershire Sauce. I also found that while it made me slightly sleepy, it took about an hour, even at the highest…

If you ask the typical layperson, he or she will say that medicine is doing wonders today. But the FDA published a 'panic bulletin' in 2008 noting that the number of new drug approval requests had declined for the first time since the approval process was established, and the typical patent attorney will tell you that the drug patenting laws are now inappropriate because they were designed to protect major therapeutic breakthroughs which are no longer happening. The death rates for many forms of cancer have not improved significantly for decades, the unsolved problems in diabetes and renal failure remain what they were a half century ago, and the last disease removed as…

Hello, I am reading about cancer treatment and the use of electron therapy. In the book im reading it states that increasing the number of beam portals leads to an improvement in dose conformity and target dose homogeniety. Im having difficulty understanding this statement - what is a beam portal? what does dose conformity mean? and target dose homogeniety? Thanks, Betty

If so, how? If not, why not? I quote from the Wikipedia article on Hypnosis: http://en.wikipedia.org/wiki/Hypnosis

Hi, I thank you all for your help....(I put this is the wrong section, so I'll try it here) There is a man on the internet saying that drinking three drops of his Miracle Mineral will cure us of 95% of all diseases, including cancer, malaria, etc. This "miracle mineral" is sodium chlorite that he says to add lemon juice so that it turns to chlorine dioxide. I noticed that my household Clorox says it is sodium hypochlorite, so I asked what the difference is, someone answered: "NaClO is household bleach. Sodium chlorite is NaClO2 Table salt is NaCl all very different substances.. and in the end how they compare makes not one hair of difference bec…

what are the protocols for the measurement of enzyme assays of inflammation (GSH, MPO, MDA, SOD and catalase) with a spectophotometer without using kits?

Hello everyone, What I just read is for type 1 diabetes mellitus, it requires an environmental factor (eg virus) and genetic determinant that allows the B cells to be detected as non self. Now I'm not very familiar with autoimmune diseases. My question is why does a virus have to come and trigger the autoimmune destruction of B cells. If B cells are alreadly genetically non self, shouldn't the body start attacking them without a stimulus? Thank you

There is a massive campaign today to save healthcare costs and improve healthcare outcomes by focusing on preventive medicine rather than just treating disease after it occurs, when care becomes more expensive and health becomes more difficult to restore. But the simple fact is that most of the truly serious diseases which cost the healthcare system the most money and which are most devastating to human health, well-being, and life cannot be prevented by any known means. Cystic fibrosis, lupus, type 1 diabetes and a host of autoimmune diseases, multiple sclerosis, muscular dystrophy, Tay-Sachs disease, muscular dystrophy, more than half of all cases of renal failure and…

Do you know if morphine is stronger than endorphine as a treatment against pain ?

Yoga A good, regular yoga practice will go far in relieving the stress and tension that sometimes cause mild back pain, and in fact, studies have shown that yoga is the number one most effective …

Check it out at www.penncmebestpractice.org. • The content is focused on improving care of patients with chronic diseases and includes preventive care. • Earn as many as 30-40 AMA PRA Category 1 Credits TM in diabetes and COPD, with activities in hypertension and immunization coming later this…

As i have studied it seems Haldol antidote is cocaine. Please comment and share some links who clarify that statement. Maybe aphethamines are more efficient lower stimulation peak and longer effect. Please comment that too. Thanks in advance

From what I understand presently, and this is tenuous knowledge, neurons come in three types: sensory, interneuron (relay neurons in the UK) and motor neurons which are in contact with muscle or glands. Some neurons are covered in a fatty non-conducting substance called myelin which speeds up the electrical impulses carried by neurons. The presence of myelin speeds up the impulses in comparison to neurons that have no myelin. Correct so far? My problem is that I want to be exact about which neurons are myelinated in the body and which are not. Therefore I need more expert help, a reference or two... and where else could I go to except here? Neurons

On Ask The Experts which is a social media site whose focus is New Technology, an interview article talks about a new procedure which will increase the speed of DNA analysis and testing. It can be found in its ATE Science and Medical secion http://www.asktheexperts.org.uk/index.php?option=com_content&view=article&id=155&Itemid=225

This fascinates me: there are some patents online on increasing melanocytes ( darkening hair and skin) It's already often done by injecting ( melanotan) but it looks like alternatives are more practical. This one for instance: <a name="OLE_LINK1">https://data.epo.org/publication-server/pdf-document?PN=EP2191819%20EP%202191819&iDocId=7331169&iepatch=.pdf I'm a redhaired person, light skin, I dislike both of them, so maybe anyone could help to put this patent into a formula? looks like it's possible, I'm just not a scientist

Healthy males can have a hemoglobin level varyng from 140 up to 180, though there is a gradual decline with age. Most medical textbooks will tell you that an otherwise healthy male patient with a hemoglobin of 130 is anemic and requires some treatment, usually in the form of iron supplements. In supportive cancer therapy, several studies have indicated that increasing patients' hemoglobin levels with erythropoietin either close to or even all the way up to the lower end of the normal range produces important benefits in quality of life. This seems logical, since evolution would not have threatened the survival of the species by creating a demand for calories to support…

Hi: The below link describes a health product I'm looking for. How long until such becomes available for $1-per-package? http://groups.google.com/group/healthiest-food-possible?hl=en&lnk= I seriously wouldn't mind living off that stuff. Along with at least 30 minutes of vigorous aerobic exercise [preceded by warm-up and stretch exercises], this would greatly increase the chances of living a long, healthy life. Thanks, Green Xenon P.S. Feel free to join that group

Although I'm used to hearing from doctors and nutritionists about milk being good for you, I've come across some almost convincing arguments for the idea that it isn't. Here's an article, though it's a bit long: http://www.notmilk.com/kradjian.html And for those who don't want to bother with the article, here's a video: It's a bit disturbing to think that even nutritionists would be misinformed on this subject; but the arguments for why they would be sound somewhat plausible. As a type 1 diabetic, I hope they find out what's causing this disease, and if it really is milk, I hope the diary industry gets punished for it.

I was reading about a recent breakthrough by the fine folks at Trinity college here in Ireland, the article in question says that A hormone called Amylin, or Islet Amyloid Polypeptide (IAPP) has been discovered to a key underlying cause to type two diabetes and the main trigger for the disease because it gets deposited in the pancreas and causes the body to produce much greater levels of insulin than it normally would. It is claimed that a drug could be designed to suppress this hormone and thus bring insulin levels back down and prevent the onset of diabetes, My question is that would the suppression of this hormone have any serious adverse effects or cause any other com…

Hi: Lets say the venom of the Portuguese Man of War jellyfish magically enters my cerebrospinal fluid. What symptoms will I experience? My guess is paralysis, involuntary movements, impaired vision/hearing, visual/auditory hallucinations, impaired balance, dizziness, vertigo, memory loss, false memories, distortion of existing memories, inability to access existing memories, loss of awareness, decreased level of consciousness, alteration in sense of time, dissociative states, tinnitus and other interesting CNS symptoms. Thanks, Green

Does anybody know what the host range is for filoviruses (i.e. Ebola and Marburg)? I mean I known that they can infect most if not all types of mammals as well as several species of birds, but I can't find the actual host range anywhere. Any help here would be appreciated.

A middle-aged, set-in-his-ways, sedentary, overweight (BMI>25), former alcoholic is controlling his diabetes with diet alone. He checks his blood sugar 8 to 10, sometimes 15, times a day, and the numbers I have seen him record are about 125 through 150 mg/dL, once as high as 200, and he says he once measured down in the 80s, which he said was "not good". He often will test his blood, gulp down a snack, and 15 to 30 minutes later, test his blood again. He claims he's heat intolerant, he seems to sweat a bit more than others do in the same situations (but I never see any beading or running sweat), he drinks a lot of ice water (sometimes a quart or two at a sitting…

For anyone who's unsure Cryonics is the freezing of humans or animals for preservation, to be "woken up" at a later stage, as the title sugests. It's an idea that has been used in science fiction while the heroes go on the adventure to other planets. Currently, people pay huge amounts of money for it in the hope they will be woken up some time in the future, when technology has advanced. Around the world 200 people have undergone the cryopreservation procedure. Cryonic procedures usually begin a few minutes after cardiac arrest, and cryoprotectants are used to drastically reduce the formation of ice. In some cryonics procedures these cryoprotectants are used in…

I just watched a documentary on the pet food industry today and these are the facts that where stated. Seems all our pet foods no name brand all the way to high end brands are ALL produced at ONE company in Toronto which controls all of north America. All these dry dog and cat foods contain grains that where shipped from China (which have been found in the past to contain plastic ) which can be harmful to your dog and are often the source of poison and recalling in the pet food industry. It's also said that even though "Chicken" may be the first ingredient on the dog food label there is x3 the amount of GRAIN. Your pets should consuming more meat then grain produc…
