What is a double blind crossover study?
I want to know if a medication has the desired effect. I'm going to give half the subjects the 'live' med, and half will get a placebo. The subjects will not know which one they are getting. That's one level of "blind". Studies show that there is a measurable affect based on the fact that the person distributing the med's knows who is getting the med and who is getting the placebo. So I am going to package the med's and give them to the distributing nurse, and the nurse will not know who is getting the med and who is getting the placebo. That is "double blind" model.

How long can frozen embryos be kept for?
No one knows what the maximum storage period might be. Procedures for human embryo freezing were developed in 1984 and only went into widespread use in the late 1980s. This means that the longest time a human embryo has been stored is 12-15 years and, typically, patients that have left embryos in storage for this long are not coming back for them. Some patients have come back after 10-12 years and the embryos have been thawed successfully. Beyond this time frame, we don't know how long an embryo will remain viable.
Are humans being born without an appendix?
Some scientists think that the appendix was made for digesting tougher materials the human would eat (to keep from starving) such a grass and leaves, but no one knows for certain what it's for.
What is the purpose of double blinding in a research trial?
"Double Blind" means that neither the doctors administering the trial nor the patients know who is taking the medication and who is on a placebo. Because no one knows which patients should be experiencing significant change, the results recorded should be less biased and exaggerated.
Why wouldn't a doctor be notified if a patient is getting a placebo or a treatment?
In a double-blind test, if the doctor treating a patient knows whether the patient is getting a real treatment or not, they may (perhaps unconsciously) treat the patient differently, or worse let slip that the patient is taking the placebo. This will affect the results (as it changes the effect of the placebo) and can ruin a drug trial.
What is a state of control in a experiment?
it is the aspect of the expierment that acts as the control meaing you do nothing to it. i.e if you have 3 people and you test two of them with a drug and give one a placebo yet none of the three knows who is getting what. you then compare the results thus the one you gave the placebo to acts as the control.
What is a blind clinical trial?

Why is double blind study reliable?
To avoid the placebo effect! If doctor knows that the substance he is giving is inert, his behavior will change. Patient is likely to note the same. If the doctor knows that he is giving the drug, his behavior will be confident. Patient will again note the same. So to avoid this placebo effect, the doctor has to be blind as well. Same is true for the patient also. So both the patient and the doctor need to be blind to have the proper study of the drug. Such study is called as double blind study and it is necessary for proper results.
What is the difference between an ER doctor and a GP?
GP: Gatekeeper of the NHS. Handles everyday patients, has around 1000-2000 patients on their "list". Knows a little about a lot of things. A&E doctor: Specialist in stabilising patients who are very unwell, due to accident or serious, sudden acute disease. Knows a lot about a little, but generally will only stabilise before discharging or sending on for further treatment.
