What cosmetic ingredients tested and which are not?

If by "tested" you mean tested on animals...well, just about every synthetic ingredient available to the cosmetics chemist has been tested on animals at some point in the past.

This is the thing about continued animal testing: It did serve a valid purpose--since they started doing it, we really haven't had a recurrence of the "Lash-Lure" crisis that brought on animal testing in the first place. (For those who are new: Lash-Lure was a permanent mascara introduced in the 1930s to make women's eyelashes dark and attractive without the need to apply mascara every day. It was an industrial fabric dye that was completely capable of dissolving your eyes, and did to many of this product's victims. When the Pure Food and Drug Act was amended to include cosmetics, the first thing the government did under its new authority was to go from warehouse to salon to store confiscating all the Lash-Lure they could find.) But today? We are treated to new and more alluring shades of cosmetics on almost a daily basis, but makeup is makeup: the ingredients and techniques used to make eye shadow are the same no matter whose name is on the package. Lipsticks are pretty much the same no matter who makes them. We know the ingredients used to make the cosmetics of today are safe, so there's no need to do any more animal testing.

What is posterolateral osteophytes in MRI repors?

Can you have a normal thyroid ultrasound result but still have hypothyroidism?

Absolutely. If you do just a bit of research you will find that hypothyroidism is a hidden condition because of the particulars in its physiology. Saliva testing may be more accurate or seeing a naturopathic doctor. Good luck!

What does tear drop present mean in a manual differential blood count?

Tear drop cells in the blood stream are most generally associated with iron deficiency anemia. While this is not an alarming finding, it suggests that there is a production problem in the bone marrow when trying to get enough iron (hemoglobin) into the red cells. If there isn't enough iron, the red cells will adapt and attempt to maximize surface area for oxygen binding by altering their shape. This is a common appearance in iron deficient states. There are a host of other changes along with tear drop cells that support the diagnosis of iron deficiency. This is also seen in other conditions that are less frequently diagnosed.

What does a 5 result on prostate test means?

If this is related to prostate cancer, it evaluates the current stage of cancer in that particular person. Generally, prostate cancer has 4 stages, however, your "5" of prostate test might be related to Gleason score.

For your information, Gleason score is a system to evaluate the changes in prostate cells and the spread of the tumor. As its range varies from 2 points to 10 points, the high points you get from prostate test; the more likely the tumor might be spread.

So, a Gleason score of 5 means, the cancer is located only in the prostate, and the PSA level is lower than 10.

What is EOSINO in a blood test?

How long after taking suboxone can you detect it in a urine drug test that is testing for suboxone?

Suboxone does not show up on a Urine test unless they specifically look for suboxone in your urine and the only reason they would do that is if they suspect that you are on something or used to be on something and even in most cases unless your going to be a cop or work for the FBI. they don't look for it. Suboxone fills only 2 out of the three receptors in your brains opiate receptors which are enough to keep you out of withdraw and take most of the cravings away and not be dected on a urine test, if you where to get tested for suboxone which i never heard of depeneds on how long you have been taking it, short term like a week or so , it would be out of your system no less than 48 hours with a half life of 24hrs. longer than a months your looking at 72hours unfortuantly.My fiance is a pharmicist and i read this information out of this special program that only pharmisicts and doctors use.So unless here program is wrong, which is doubtful that's your answer

You have bee taking methocarbamol 750mg and am about to take a urine test when do you need to stop taking the methocarbamol?

For a drug test involving illegal substances, and abuse of prescription drugs, methocarbomol causes no problems. If you are worried about the discoloration of your urine to either black or green (one of the listed side effects) don't. The odd color of your urine can be explained to the persons giving the test. If they are skeptic, or you don't want people to know you are taking the drug, simply let them observe you. This way, they know that you haven't tampered with your sample. For medical urinalysis on the other hand, whether you need to stop taking the drugs depends on the test being done. If you actually hold a prescription for methocarbomol ask your doctor or the laboratory doing your tests before you stop taking the drug. If you do not have a prescription for methocarbomol, simply using the substance may change levels of different things that the lab is testing for. Once again, ask the lab and/or your doctor if your medication will interfere with the testing being done. Should you not want to speak with your doctor or the laboratory about the medications you are taking, the sooner you stop taking them the better your chances are that your tests will go back to normal. You could safely say a minimum time is a week, and maximum time is a month. Remember everyone reacts differently to different substances, and someone else's experience might not be the same as yours. -swp1000-

I have a mirro 4 quart pressure cooker that leaks steam where the vent tube is screwed into the top. Is there a liquid used to seal the vent tube on the top of a pressure canner?

Actually, this is more lilely to be consensate from the regulator weight. Some of the steam condenses on the weight and drips down the tube. The lid is hot enough that it then biols and appears to be a leak. I can with 4 different pressure canners, of 3 different manufactures, and they all do it. Wrap a bit of cleanex or paper towel, and the water will be absorbed until is gets saturated. If the steam continues without wqiting for the towel to get wet, then it may be leaking a bit. You can also remove the vent stem, and reset it with teflon plumber's tape. The pressure and temp are well below the tolerences of the tape. It will seal most minor leaks.

What is a placebo used for in scientific studies?

Placebo is a dummy drug, which is identical in appearance to the drug under study but will have no therapeutic property.

Placebos are used in clinical trials in order compare the effect of drugs on humans. The placebos are given to the control group and the drug is given to the treatment group.

The effects on both the groups are then documented and compared to see the action of the drug in humans.

Placebos are used in randomized, controlled trials.

How many moles of oxygen in red blood cells of 71 kg man if all hemoglobin molecules were saturated?

OK, the best I can give for this is a very rough estimate that should be reasonable in terms of orders of magnitude. Actual numbers would vary greatly amongst individuals. Using the Wikipedia entry for Erthocytes (Red Blood Cells or RBC's) an average adult male has 3 x 10 ^13 RBC in their body, and each RBC has 270 million Hemoglobin molecules (which is AMAZING, as each of these is a very complex protein of more than 4000 atoms, that have to arranged in exacting detail to function), and each hemoglobin molecule has 4 Heme units that have the Iron Ion in them that can bind one molecule of Oxygen. So 3 x 10^13 times 270 x 10^6 times 4 gives you the total number of Oxygen molecules that would be bound by all these RBC's if they were all simultaneously saturated with 4 oxygens per hemoglobin molecule. That gives 3.24 x 10^22 molecules of oxygen bound to hemoglobin. Then dividing 2.24 x 10^ 22 by Avogadro's number 6.02 x 10^23 we get 0.053 moles of Oxygenbound to the all the hemoglobin in all the RBC's of an Adult male.
