Peran Terapi Akupunktur Pada Nyeri Tulang Metastasis

Bone pain caused by cancer is a common complication in bone metastasis. Bone pain has the characteristic triad of pain including continuous pain, spontaneous pain and incident pain. Various mechanisms that allow bone metastasis can cause pain have been reported. These mechanisms include the possibility of local production of growth factors and cytokines. The management of the pain bone metastasis include aspects of pharmacological and non-pharmacological therapies. Acupuncture can play a role in the treatment of bone metastasis pain through modulation of various neurotransmitters and increase the production of endogenous opioids that can cause analgesika effect. This paper describes a male patient aged 62 years old with painful bone metastasis who experience an improvement after acupuncture therapy, with the goal of providing information on the possible use of acupuncture for painful bone metastasis

Mechanical properties of wood polymer composites (WPCs) after prolonged ultra-violet (UV) irradiation exposure

This research aims to compare the mechanical properties of WPC made from 30 % of rice husk as fibre and 70 % of polypropylene as polymer with and without prolonged UV irradiation exposure. WPC samples are tested with UV irradiation at 5000, 10000, 15000 and 20000 hours with temperature 50 °C and tested with compression test (ASTM D695-15) and tensile test (ASTM D638-02), while physi-cal properties characterization was done by density test (ASTM D792-13) and OM test. The compression and tensile result shows de-crease value of mechanical properties due to the presence of chain breaking activity contributed from the process of photo oxidation throughout the UV exposure. The effect of UV exposure also resulted in decrease of WPC samples density value as the longer the expo-sure, the lower the samples density due to the losses of volatile particle. In conclusion, the weather ability of WPC was observed by pro-longed exposure to UV radiation thus highlights the influence of parameters involved in the degradation rate of WPC as to contribute a good guidelines and resolution for the future growth of polymer composite structure
