Nomilin is a triterpenoid present in common edible citrus fruits with putative anticancer properties. In this study, the authors investigated the antimetastatic potential of nomilin and its possible mechanism of action. Metastasis was induced in C57BL/6 mice through the lateral tail vein using highly metastatic B16F-10 melanoma cells. ⋯ Nomilin treatment also exhibited a downregulated Bcl-2 and cyclin-D1 expression and upregulated p53, Bax, caspase-9, caspase-3, p21, and p27 gene expression in B16F-10 cells. Proinflammatory cytokine production and gene expression were found to be downregulated in nomilin-treated cells. The study also reveals that nomilin could inhibit the activation and nuclear translocation of antiapoptotic transcription factors such as nuclear factor (NF)-κB, CREB, and ATF-2 in B16F-10 cells.

AIMS. This study aimed to give an up-to-date description of the views and knowledge that health professionals in New Zealand (NZ) have about complementary and alternative medicine (CAM) and its use in the context of integrative medicine. ⋯ Integrative medicine is increasingly being accepted in medical practice, although many doctors still do not agree with the use of CAM. There is a need for increased patient-doctor discussions of CAM use. Doctors' lack of knowledge about CAM may be a barrier to communication and should be addressed with specific medical training.

The effect of Vernonia cinerea Less. extract on the inhibition of lung metastasis induced by B16F-10 melanoma cells was studied in C57BL/6 mice. V cinerea extract significantly (P < .001) inhibited lung tumor formation (78.8%) and significantly increased the life span (72.5%). Moreover, lung collagen hydroxyproline, uronic acid, and hexosamine and also serum sialic acid, γ-glutamyltransferase (GGT), and vascular endothelial growth factor (VEGF) levels were found to be significantly (P < .001) lower in treated animals compared with untreated controls. ⋯ V cinerea extract administration could suppress or downregulate the expression of matrix metalloproteinase (MMP)-2, MMP-9, lysyl oxidase, prolyl hydroxylase, K-ras, extracellular signal-regulated kinase (ERK)-1, ERK-2, and VEGF and also upregulate the expression of nm-23, tissue inhibitor of metalloproteinase (TIMP-1), and TIMP-2 in the lung tissue of metastasis-induced animals. It also inhibited the protein expression of MMP-2 and MMP-9 in gelatin zymographic analysis of B16F-10 cells. These results indicate that V cinerea could inhibit the metastatic progression of B16F-10 melanoma cells in C57BL/6 mice by regulating MMPs, VEGF, prolyl hydroxylase, lysyl oxidase, ERK-1, ERK-2, TIMPs, nm23, and proinflammatory cytokine gene expression in metastatic lung tissue.

Randomized Controlled Trial
Impact of relaxation training according to Yoga In Daily Life® system on perceived stress after breast cancer surgery.
The purpose of this pilot study was to gather information on the immediate and short-term effects of relaxation training according to Yoga In Daily Life(®) (YIDL) system on the psychological distress of breast cancer patients. 32 patients at the Institute for Oncology of Ljubljana were randomized to the experimental (N=16) and to the control group (N=16). Both groups received the same standard physiotherapy for 1 week, while the experimental group additionally received a group relaxation training sessions according to YIDL(®) system. At discharge the experimental group was issued with audiocassette recordings containing the similar instructions for relaxation training to be practiced individually at home (for further 3 weeks). ⋯ Patients who received relaxation training reported feeling significantly less distressed during hospitalization and after discharge-period than did the controls that did not receive relaxation training. The results indicate that relaxation training according to Yoga in Daily Life(®) system could be useful clinical physiotherapy intervention for breast cancer patients experiencing psychological distress. Although this kind of relaxation training can be applied to clinical oncology in Slovenia, more studies need to be done.

Acupuncture is underutilized as an adjunct cancer therapy. The main study objectives were to determine the feasibility of administering acupuncture as palliative therapy to patients with advanced ovarian or breast cancer and to assess the effect on symptoms and quality of life (QOL). ⋯ This pilot study demonstrates that an 8-week outpatient acupuncture course is feasible for advanced cancer patients and produces a measurable benefit that should be evaluated in controlled trials.
