We also explore other prospective applications and discuss the corresponding concepts,issues,approaches,and challenges,with the aim of stimulating broader interest in gold nanorod-based nanotechnology and improving its practical application.展开更多

Methods Nine individuals of both sexes, chosen randomly, paricipated in this study. The temperature of the room where the experiment was carried out was not above 21 ℃. At the start of the experiment the volunteer stayed for exactly ten minutes in the room for acclimaizaion, then the first thermographic image was recorded for standardizaion purposes. Following this, an acupuncture needle was inserted at KI 3 only in the right leg, whose depth was limited to obtain Deqi, only manual stimulation for 15 min permanence in the site. Ater this period, new images were recorded. Results Significant reduction of all the right leg temperatures, by about 1.1 ℃ in all the volunteers that received the acupuncture at the Kl 3 was noted, with a coefficient variaion of P<0.0001 that was staisically highly significant, while on the other not simulated leg the variaion that occurred was around 0.7 ℃, with no significant coefficient variation of P>0.05. Conclusion The results of this study demonstrate that manual simulaion of the Kl 3 influences significantly peripheral vascular circulation, by means of sympathetic stimulaion causing vasoconstricion.展开更多
