Pao extract, derived from bark of Amazonian tree Pao Pereira, is commonly used in South American medicine. A recent study showed that Pao extract repressed androgen-dependent LNCaP prostate cancer cell growth. We hypothesize that Pao extract asserts its anticancer effects on metastatic castration-resistant prostate cancer (CRPC) cells. ⋯ Finally, forced expression of NFκB/p65 reversed the growth inhibitory effect of Pao extract. Overall, Pao extract induced cell growth arrest, apoptosis, partially through inhibiting NFκB activation in prostate cancer cells. These data suggest that Pao extract may be beneficial for protection against CRPC.

African American breast cancer survivors engage in less physical activity compared with their Caucasian counterparts. There is a need for exercise intervention research that focuses on improving the overall health and long-term survivorship of African American breast cancer survivors, especially because they often have worse outcomes than Caucasian survivors. Study objectives were to determine whether African American participants increase physical activity and explore whether exercise had a positive impact on fitness and health. ⋯ The intervention led to increased physical activity. As a result of increased levels of physical activity, improvements on several fitness/health parameters occurred.

Pain control is an ongoing challenge in the oncology setting. Prior to implementing a large randomized trial at our institution, we investigated the feasibility, safety, and initial efficacy of acupuncture for uncontrolled pain among cancer patients. ⋯ Acupuncture was feasible, safe, and a helpful treatment adjunct for cancer patients experiencing uncontrolled pain in this study. Randomized placebo-controlled trials are needed to confirm these results.

Metastasis is an extremely complex process that is a major problem in the management of cancer. In the present study, we had evaluated the antimetastatic activity of DECALEPIS HAMILTONI: using B16F-10 melanoma-induced experimental lung metastasis in a C57BL/6 mice model. ⋯ treatment could alter proinflammatory cytokine production and could inhibit the activation and nuclear translocation of p65 and p50 subunits of nuclear factor κB in B16F-10 cells.

Managing cancer-related chronic pain is challenging to health care professionals as well as cancer patients and survivors. The management of cancer-related pain has largely consisted of pharmacological treatments, which has caused researchers to focus on neurotransmitter activity as a mediator of patients' perception of pain rather than the electrical activity during neurobiological processes of cancer-related pain. Consequently, brain-based pain treatment has focused mainly on neurotransmitters and not electrical neuromodulation. ⋯ Initial research in nononcology populations suggests that encouraging neuroplasticity through a learning paradigm can be a useful technique to help treat chronic pain. Here we review evidence that indicates a measurable link between brain activity and patient-reported psychological and physical distress. We also summarize findings regarding both the neuroelectrical and neuroanatomical experience of symptoms, review research examining the mechanisms of the brain's ability to modify its own activity, and propose a brain-computer interface as a learning paradigm to augment neuroplasticity for pain management.
