Solid tumors can hijack many of the same programs used in neurogenesis to enhance tumor growth and metastasis, thereby generating a plethora of neurogenesis-related molecules including semaphorins Among them, we have identified Semaphorin7A (SEMA7A) in breast cancer We first used to the DA-3 mammary tumor model to determine the effect of tumor-derived SEMA7A on immune cells We found that tumor-derived SEMA7A can modulate the production of proangiogenic chemokines CXCL2/MIP-2 and CXCL 1, and...

- Title
- Partnering: An exploration of the process occurring between couples engaged in a Partner Breast Exam Program.

- Abstract/Description
-
The purpose of this study was to gain an understanding of what happens when partners participate in the Partner Breast Exam Program. A qualitative research design, using a grounded theory approach was used to understand the perspective of the couples participating in "Men Can Too" a Partner Breast Exam program. This approach was chosen because the experience of participation in Partner Breast Exam is "unchartered territory." Preliminary findings suggest that the process of partnering results...

A qualitative research design, using a grounded theory approach was used to understand the perspective of the couples participating in "Men Can Too" a Partner Breast Exam program. This approach was chosen because the experience of participation in Partner Breast Exam is "unchartered territory." Preliminary findings suggest that the process of partnering results in a synergy between the couples. The three processes that comprise the Dynamics of a Synergistic Couple include: Sharing, Dyad: Male/Female Interaction, and Motivation. Partnering, by removing barriers such as fear, can promote a shared journey toward health for a couple, where they become synergistic partners in health, when they share the burden.
