Patient discussion about negative

Q. is her2 positive more agressive than her2 negative? i know someone with her2 positive breast cancer and her doctor said it was more difficult to detect upon its return if it came back i want to know if it is true and what can she do to detect it earlier

A. Over-expression of her2/neu, a specific molecule in the breast cancer cell is indeed considered to convey worse prognosis, and suggest the need for chemotherapy and immunotherapy with Herceptin. However, the decision is much more complicated and should be made on case by case basis after consulting a professional.

Q. Rising PSA to 10 with two negative biospies? Expect cancer? 67 yrs old in good health otherwise.

A. High values don't always mean it's cancer. At 67 years old, you're prostate is most likely enlarging, resulting in the higher PSA results. And after two negative biopsies, it sounds like you're in the clear. Like Brandon said though, keep up with your regular check ups.

Q. Does the cooking have a negative effect on the protein content of the food? I have heard that high temperatures cooking breaks the protein, so does the cooking have a negative effect on the protein content of the food?

A. Yes. Proteins can be denatured by heat, but only when the protein structure is delicate or is exposed to extremely high temperatures for long time. You must remember that breaking of protein is the physical-chemical process where the physical or chemical structure of a protein is rearranged. So cooking will not reduce on the nutritive value of the food until it’s cooked at cooking temperatures.

These major theoretical contributions have enabled NEG researchers to operate with several key-terms: the general equilibrium model of a spatial economy, which is different from the approach derived from the traditional theory of location and economic geography; increasing returns or indivisibilities of the individual producer, which prevent the economy to degenerate into a "backyard capitalism" (in which every household produces for personal consumption); imperfect competition, due to increasing returns; transport costs, which make location matter; changing the location of production factors and consumers is a prerequisite for agglomeration.
