mass number (A) the number of nucleons (protons plus neutrons) in the atom of a nuclide; generally indicated by a superscript preceding the symbol of a chemical element (e.g., 131I), denoting a specific isotope.
oxidation number a number assigned to each atom in a molecule or ion that represents the number of electrons theoretically gained (positive oxidation numbers) or lost (negative numbers) in converting the atom to the elemental form.

Patient discussion about number

Q. what is a safe tumor marker number range?

A. depends on the marker...most of the markers are materials that found normally in our body. and there are a number of markers and their levels differentiate. what marker do you mean?

Q. What are the percentage of people dealing with breast cancer out of the number of people that are illness with cancer ? and what is the percentage of death cases out of sum of all cases of breast cases ? is there any difference between the amount of death cases from breast cancer and than the other kinds of cancer ?

A. here's a quote from the CDC site:
"Aside from non-melanoma skin cancer, breast cancer is the most common form of cancer in women. Breast cancer is the number one cause of cancer death in Hispanic women. It is the second most common cause of cancer death in white, black, Asian/Pacific Islander, and American Indian/Alaska Native women."

Q. i have heard that number of scientists found out in one of there researches that breasts Cancer is capable to just disappear with out a treatment , have any one read this article/research ? or maybe just heard about it ? because it is interesting why and how this result happens ...

A. hi pinkofdestiny - try also these links, i know and read a lot about the books of Phillip Day and recommend them to everybody. cancer can be healed and there are also ways to make with success prevention:

before a woman should loose her breast, she should make a therapy with vitamine B17 - the vitamin which can eliminate cancer in any form, but you should not know about it! it is terrible, but it is the way how politicians and industry-trust treat us.

References in classic literature ?
To keep up a mixed stock of even such extremely close varieties as the variously coloured sweet-peas, they must be each year harvested separately, and the seed then mixed in due proportion, otherwise the weaker kinds will steadily decrease in numbers and disappear.
If we wished to increase its average numbers in its new home, we should have to modify it in a different way to what we should have done in its native country; for we should have to give it some advantage over a different set of competitors or enemies.

The offspring, also, will thus have a better chance of surviving, for, of the many individuals of any species which are periodically born, but a small number can survive.
The Indians had spies out viewing our movements, and were greatly alarmed with our increase in number and fortifications.

Von Horn, possibly intentionally, misinterpreted the other's motive, and raising his bull whip struck Number Thirteen a vicious cut across the face, at the same time levelling his revolver point blank at the broad beast.
Number Thirteen knew nothing of the danger of firearms, but the noise had startled him and his experience with the stinging cut of the bull whip convinced him that this other was some sort of instrument of torture of which it would be as well to deprive his antagonist.
Again Number Thirteen translated the intent without understanding the words, and releasing von Horn permitted him to rise.
