A 77-year-old man had cataract surgery in the left eye in March 2017. A toric intraocular lens (IOL) was implanted because of astigmatism. The postoperative meridian of the IOL was located nearly exactly in the planned meridian, which was controlled 1 week later with ray-tracing aberrometry (iTrace) and the smartphone application Axis Assistant. The referring ophthalmologist proceeded directly with a neodymium:YAG (Nd:YAG) laser posterior capsulotomy in his own office, after which the meridian of the implanted toric IOL was rotated more than 115 degrees...

This article provides a new definition of an acupuncture meridian. It suggests that a meridian consists of a distal tract of tissue that is affected by organ function. In the 1960's, Kim discovered the primo vascular system, and regarded the superficial primo vessels as equating to the meridians. Instead, this article suggests that the superficial primo vessels merely underlie the meridians, in that they enable their creation, which is why some meridians are said to occur along the paths of superficial primo vessels...

Hominis placenta (HP), a dried human placenta, has been known to target liver, lung, or kidney meridians, improving the functions associated with these meridians in traditional Chinese or Asian medicine (TCM). Since recent studies implicate an HP extract in suppressing inflammation, we investigated whether an aqueous HP extract can ameliorate inflammation that occurred in the lungs. When administered with a single intratracheal lipopolysaccharide (LPS), C57BL/6 mice developed an acute neutrophilic lung inflammation along with an increased expression of pro-inflammatory cytokine genes...

One leading hypothesis on the nature of visual callosal connections (CC) is that they replicate features of intrahemispheric lateral connections. However, CC act also in the central part of the binocular visual field. In agreement, early experiments in cats indicated that they provide the ipsilateral eye part of binocular receptive fields (RFs) at the vertical midline (Berlucchi and Rizzolatti, 1968), and play a key role in stereoscopic function. But until today callosal inputs to receptive fields activated by one or both eyes were never compared simultaneously, because callosal function has been often studied by cutting or lesioning either corpus callosum or optic chiasm not allowing such a comparison...

In Treatise on Febrile Diseases , ZHANG Zhongjing had used Qimen (LR 14) for the most times compared with other acupoints among the limited numbers of acupuncture prescriptions. Qimen (LR 14) is the front- mu point of the liver meridian, acting on smoothing liver qi and regulating qi activity. It is commonly used to treat the disorders caused by retarded circulation of qi and blood, such as distension and pain of the hypochondriac region and masses. Based on the opening-closing-pivot theory of the six meridians, the specificity of the running course of the jueyin meridian and the property of Qimen (LR 14), the mechanisms of Qimen (LR 14) were analyzed on the treatment of febrile diseases, aiming to enhance the considerations and application of this points in clinical practice and contribute to the further understanding of ZHANG Zhongjing ' s academic thoughts on the syndrome differentiation in the treatment of diseases...

BACKGROUND: Sinew acupuncture is a new modality of acupuncture in which needles are inserted into acupoints, ashi points or spasm points of sinew and muscles along the meridian sinew pathway. A previous observational study revealed that sinew acupuncture has immediate analgesic effects on various soft tissue injuries, including knee injuries. However, no rigorous trials have been conducted. This study aims to examine whether sinew acupuncture can safely relieve pain and symptoms of knee osteoarthritis (KOA) and improve patients' functional movement and quality of life...

Background: Accumulating evidence from anatomical, physiologic, and neuroimaging research shows that Classical acupuncture points stimulate nerve trunks or their branches in the head, trunk, and extremities. The first part of this series revealed that phenomenon in the extremities. Principal meridian distributions mirror those of major peripheral nerves there and Classical acupuncture points are proximate to peripheral nerves there. These relationships were shown to be consistent with the linear neuroembryologic development of the extremities...

Blurred image restoration poses a great challenge under the non-Gaussian noise environments in various communication systems. In order to restore images from blur and alpha-stable noise while also preserving their edges, this paper proposes a variational method to restore the blurred images with alpha-stable noises based on the property of the meridian distribution and the total variation (TV). Since the variational model is non-convex, it cannot guarantee a global optimal solution. To overcome this drawback, we also incorporate an additional penalty term into the deblurring and denoising model and propose a strictly convex variational method...
