Patient discussion about neg

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.

Furthermore, the personal NEGs of SRFE owners align with the perceived benefits of regional food consumption often sought by consumers (e.
Accordingly, Table 1 illustrates, with a discussion to follow, how value co-creation may act as a mechanism that draws common SRFE owners' personal NEGs together with the perceived benefits of regional food consumption, to help enhance the value creation component of SRFE business models.
The following expands on the suggestions presented in Table 1, providing some practical examples of how value co-creation may manifest in relation to SRFE owners' personal NEGs.
In fact, although the N is very small (4), non-EPA respondents rate themselves as having less total personal impact (a higher score) in reg negs (score = 5.
We asked the survey respondents who had participated in a reg neg to identify a conventional rule that they were personally familiar with and that seemed comparable to the rule they had helped to negotiate.
They were not asked directly to compare reg neg to conventional rule making, either generally or on a given dimension.

The main field of application of NEGs is in sealed-off devices such as microwave tubes and x-ray tubes.
The gettering action of NEGs, such as St-101 (Zr-Al alloy), St-707 (Zr-V-Fe alloy), and St-185 (Ti-V alloys) from SAES Getters SpA, Milano, Italy, begins with gas transport to the alloy surface.
NEGs are being used increasingly in combination with ion pumps, especially in very large conductance-limited vacuum systems such as colliders and particle accelerators where both the ion pumps and the NEG pumps are usually built-in and provide a so-called distributed pumping action.
I am excited about the contract and the new direction for NEGS and a way for NEGS to continue with our goal of bringing Alternative Energy or energy savings products to market," stated Dr.
