Several authors have discussed a pattern of behavior that has been called Compulsive Sexual Behavior, Sexual Addiction, or Hypersexuality. The literature concerning this disorder is reviewed. It is suggested that the various labels applied to this disorder are inaccurate descriptions that are not reflective of the true nature of the condition. It is further(More)
Toll-like receptors are important in the activation of innate immunity, and CD40 is a molecule critical for many T and B cell responses. Whereas agonists for either pathway have been used as vaccine adjuvants, we show that a combination of Toll-like receptor (TLR)7 and CD40 agonists synergize to stimulate CD8+ T cell responses 10-20-fold greater than the(More)
We have investigated the mechanisms whereby adoptively transferred murine CD8+ lymphocytes mediate tumor regressions. Noncytolytic, CD8+ tumor-infiltrating lymphocytes (TIL) eradicated established lung tumors in irradiated mice. Many cytolytic and noncytolytic CD8+ TIL cultures specifically secreted interferon gamma (IFN-gamma) and tumor necrosis factor(More)
This review focuses on the emerging body of literature suggesting a critical role for CD40/CD154 interactions in antigen-presenting cell (APC) activation, CD4+ and CD8+ T cell priming, and effector T cell maturation. In this context effective antigen presentation involves not only T cell expansion and long-term survival but also the ability of the APC to(More)

Some optical properties of a highly scattering medium, such as tissue, can be reconstructed non-invasively by diffuse optical tomogra-phy (DOT). Since the inverse problem of DOT is severely ill-posed and nonlinear, iterative methods that update Green's function have been widely used to recover accurate optical parameters. However, recent research has shown(More)
Lymph node biopsy is employed in many cancer surgeries to identify metastatic disease and to determine cancer stage, yet morbidity and diagnostic delays associated with lymph node biopsy could be avoided if noninvasive imaging of nodal involvement were reliable. Molecular imaging has potential in this regard; however, variable delivery and nonspecific(More)
PURPOSE A new approach to spectroscopic imaging was developed to detect and discriminate microscopic pathologies in resected breast tissues; diagnostic performance of the prototype system was tested in 27 tissues procured during breast conservative surgery. EXPERIMENTAL DESIGN A custom-built, scanning in situ spectroscopy platform sampled broadband(More)
N-of-1 trials target actionable mutations, yet such approaches do not test genomically-informed therapies in patient tumor models prior to patient treatment. To address this, we developed patient-derived xenograft (PDX) models from fine needle aspiration (FNA) biopsies (FNA-PDX) obtained from primary pancreatic ductal adenocarcinoma (PDAC) at the time of(More)
Nationally, 25% to 50% of patients undergoing lumpectomy for local management of breast cancer require a secondary excision because of the persistence of residual tumor. Intraoperative assessment of specimen margins by frozen-section analysis is not widely adopted in breast-conserving surgery. Here, a new approach to wide-field optical imaging of breast(More)
The chaotic vascular network surrounding malignant tumors leads to pulsatile blood flow patterns that differ from those in benign regions of the breast. This study aimed to determine if high-speed electrical impedance tomography (EIT) is able to detect conductivity changes associated with cyclic blood-volume changes and to gauge the potential of using these(More)
