Ultrasonic wave is largely attenuated through cancellous bone, and it was reported that attenuation of ultrasound propagating and acoustic velocity in bone is used widely for bone assessment [ 18, 23].
It has been reported that fenofibrate induced attenuation of Akt and/or Erk1/2 activity in prostate cancer [ 6], hepatocellular carcinoma [ 10], melanoma [ 14], medulloblastoma [ 16] and glioma [ 12].
Recently it has been reported that autophagy induction by SIRT6 through attenuation of insulin-like growth factor signaling is involved in human bronchial epithelial cell senescence (Takasaka et al., 2014).
It has been reported that the wireless link between the sensor and the hub experiences severe attenuation of the order of 50 to 100 dB.
Recently, it has been reported that RMD has physiological effects in human such as improvement of bowel movement [ 13], improvement of glucose tolerance [ 2], and attenuation of postprandial blood triglyceride elevation [ 7].
Contrary to that study, it was reported that PGC-1β overexpression resulted in the attenuation of macrophage-mediated inflammation by strongly inhibiting proinflammatory cytokine production [ 20].
Importantly, it was reported that inhibition of Ang II signaling resulted in near complete attenuation of skeletal muscle hypertrophy in a model of synergist ablation [23], [24], suggesting that Ang II may regulate skeletal muscle hypertrophy.
Also, it is reported that oral intake of vitamin C for 6 months in AD mouse model showed an attenuation of A β oligomerization and behavioral decline, but not reduction of brain plaque deposition.
Zigzag inserts have been reported to be efficient for vibration attenuation.
Recently, the quality of abdominal fat attenuation has been reported to be associated with cardiometabolic risk, suggesting that evaluation of adipose tissue quality as well as quantity may be useful [ 31].
