The Influence of Ceramic Far-Infrared Ray (cFIR) Irradiation on Water Hydrogen Bonding and its Related Chemo-physical Properties
摘要： The property of water is highly related to the earth's environment and climate change. The fundamental dynamical process of water is include formation and breaking of hydrogen bonds. This dynamic process, so far, is still poorly understood. We investigated weakening of the hydrogen bonds of water after ceramic Far-Infrared Ray (cFIR) irradiation and the resulting effects on physical and chemical properties of water. In this study, the Fourier transform infrared spectroscopy (FT-IR) was used to explore hydrogen bonding change of cFIR-irradiated water; in addition, capillary viscometers, Gas Chromatographs (GC), Differential Scanning Calorimetry (DSC), contact angles, Franz cells, High-Performance Liquid Chromatography (HPLC), and capillary electrophoresis analysis were used to evaluate its physical characteristics, such as viscosity, volatility, temperatures of water crystallization, surface tension, diffusion, hydrogen peroxide dissociation, solubility of solid particles, and changes in pH of acetic acid. The cFIR treated water decreased in viscosity and surface tension (contact angles), but increased in the solubility of solid particles, hydrogen peroxide dissociation, temperatures of water crystallization, and acidity of acetic acid. The weakening of water hydrogen bonds caused by cFIR irradiation is correspondent with our previous medical-biological studies on cFIR.

Protective potentials of far-infrared ray against neuropsychotoxic conditions
摘要： Compelling evidence suggests that far-infrared ray (FIR) possesses beneficial effects on emotional disorders. However, the underlying mechanism conveyed by FIR remains unclear. Recently, we demonstrated that exposure to FIR induces antioxidant potentials via up-regulation of glutathione peroxidase (GPx)-1 gene. The antioxidant potentials might be important for the modulation on the neuropsychotoxic conditions. Exposure to FIR protects from methamphetamine (MA)-induced memory impairments via phosphorylation of ERK 1/2 signaling by positive modulation of protein kinase C δ (PKCδ), M1 muscarinic acetylcholine receptor (M1 mAChR), and nuclear factor E2-related factor 2 (Nrf2) transcription factor. In addition, exposure to FIR positively modulates MA-induced behavioral sensitization via attenuating mitochondrial dysfunction by down-regulation of dopamine D1 receptor. In this mini-review, we have discussed with the protective potentials mediated by FIR against MA-induced psychotoxic burdens.

A Graphenea??Based Flexible Device as a Specific Fara??Infrared Emitter for Noninvasive Tumor Therapy
摘要： Noninvasive treatments are emerging as a promising strategy not only due to their non-invasive nature, but also due to their additive effects to traditional radiotherapy and chemotherapy. Herein, specific far-infrared rays generated from single-layer, graphene-based devices are applied to tumors as a novel noninvasive therapeutic strategy. In MDA-MB-231 breast cancer cell xenograft and metastasis models, irradiation generated from this flexible device reduces the rate of tumor growth and the number of metastatic nodules per lung by 42% and 55%, respectively. This result might be induced by the similarity between the emission spectra of the device and the absorption spectra of the living tissue. With its high energy conversion and safety, the graphene-based device can serve as an adjuvant therapeutic instrument for combined tumor treatment.

The Ceramics Radiating Far Infrared Ray Energy (Rhyolite) Promote the Formation of Bone
摘要： Far infrared ray (FIR) energy radiated by the natural ceramics (Rhyolite) cooled FIR ceramics activates water molecules and blood circulation to stimulate skin and other tissues. The aim of our study is to make clear whether the FIR ceramics radiating FIR energy affect or not on the new bone formation in vivo and in vitro. Methods: MC3T3-E1 cells were cultured in FIR CO2 incubator. The cell proliferation and the gene expression were analyzed by using WST-8 assay kit, RT-PCR and micro array analysis. The enzyme activities were analyzed by using the apiRZYM kit. Furthermore, titanium and natural FIR ceramics compounds were implanted under the periosteium of rat skull bone by injection method. Four weeks later, the samples were examined by the light microscope and micro CT analyses. Results: Proliferation of MC3T3-E1 cell was and DNA concentrations were inhibited by FIR energy radiation. The ALP activities were accelerated and the area of calcification nodules increased on 4 weeks. The RT-PCR data showed that the gene Runx2, Osterix, BSP, OCN, Col1a1 and OPN expression of MC3T3-E1 osteoblast like cells was activated. Bone mineral density (BMD mg/cm2) of implanted sites of T50-F50, T25-F75 and F100 groups was significantly enhanced after 4 weeks compared with control groups. This data shows FIR energy radiation by the natural FIR ceramics promoted bone-forming activity of osteoblasts. Significance: This study suggested that new bioactive ceramics such us natural FIR ceramics was useful for some clinically applications to repair bone defects for example of dental implant surgery.
