Binaural beat technology may exhibit positive effect on self-reported psychologic measures, especially anxiety. Further research is warranted to explore the effects on anxiety using a larger, randomized and controlled trial.

Summary In different inflammatory disease models, heat‐shock proteins (hsp) and hsp‐derived peptides have been demonstrated to possess anti‐inflammatory properties. While some studies have shown that hsp can directly interact with antigen‐presenting cells, others report that bacterial hsp can induce specific T cells with regulatory phenotypes. Effective characterization of the immunomodulatory effects of hsp 70, however, has historically been confounded by lipopolysaccharide (LPS) contamination. In this study, we compared the effects of LPS‐free Mycobacterial tuberculosis hsp 70 (TBhsp70) and its possible contaminants on dendritic cells (DC). We demonstrate herein that LPS‐free TBhsp70 inhibits murine DC maturation in vitro, while LPS‐contaminated TBhsp70 induces DC maturation. Mock recombinant preparations have no effect. In contrast to LPS, TBhsp70 does not induce tumour necrosis factor‐α production by DC, but interleukin‐10. In vivo, only LPS‐contaminated TBhsp70 induces up‐regulation of CD86 in splenic mature DC. Finally, TBhsp70 inhibited phytohaemagglutinin‐induced T‐cell proliferation. Our results support the hypothesis that TBhsp70 does not have inflammatory potential, but rather has immunosuppressive properties.

TAT warrants further research for weight-loss maintenance. Any further research on qigong should use a modification of our protocol.

We did not find support for steady-state entrainment of the scalp-recorded EEG while listening to 7-Hz binaural beats. Although our data indicated increased depression and poorer immediate recall after listening to binaural beats, larger studies are needed to confirm these findings.

SUMMARYCytokines are key modulators of the immune responses that take place in the inflamed synovium of arthritis patients. Consequently, substances that can reverse the inflammatory profile of the inflamed joint are potential tools for clinical management of the disease. Mycobacterial heat shock protein 70 (MTBHSP70) has been found to protect rats from experimentally induced arthritis through the induction of interleukin (IL)-10-producing T cells. In this study, we have demonstrated that MTBHSP70 induces IL-10 production in synoviocytes from arthritis patients and peripheral blood monoculear cells (PBMCs) from both patients and healthy controls. IL-10 production was accompanied by a decrease in tumour necrosis factor (TNF)-a production by synovial cells. Separation studies showed that the target cells were mainly monocytes. Accordingly, we observed that MTBHSP70 delayed maturation of murine bone marrow-derived dendritic cells. Our results suggest that MTBHSP may act on antigen-presenting cells (APCs) to modulate the cytokine response in arthritis and support an anti-inflammatory role for this protein, suggesting that it may be of therapeutic use in the modulation of arthritis.
