Two potent endogenous opioid peptides, endomorphin-1 (EM-1) and -2 (EM-2), which are selective micro-opioid agonists, have been identified from bovine and human brain. These endomorphins were demonstrated to produce a potent anti-allodynic effect at spinal level. In the present study, we further investigated their supraspinal anti-allodynic effects and(More)
BACKGROUND Urinary homovanillic acid (HVA)/vanillylmandelic acid (VMA), orotic acid (OA), and homogentisic acid (HGA) are diagnostic biomarkers of neuroblastoma, ornithine carbamoyl transferase deficiency (OCTD), and alkaptonuria (AKU), respectively. In this study, a high-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was(More)
We construct an MSSM-like model from intersecting D-branes in Type IIA theory on the Z2 ×Z2 orientifold where the D-branes wrap rigid 3-cycles. Because the 3-cycles are rigid, there are no extra massless fields in the adjoint representation, arising as open-string moduli. The presence of these unobserved fields would create difficulties with asymptotic(More)
The dynamic equations of a micro-positioning Scott-Russell (SR) mechanism associated with two lexible hinges and an offset are developed to calculate the output responses. Both rigid and flexible hinges are considered to explore the results. The manufacturing inaccuracy of the SR mechanism definitely causes geometric offsets of flexure hinges, and affects(More)
Metamaterial leaky wave antennas (MTM-LWAs), one kind of frequency scanning antennas, exhibit frequency-space mapping characteristics that can be utilized to obtain a sufficient field of view (FOV) and reconstruct shapes in both remote sensing and microwave imaging. In this article, we utilize MTM-LWAs to conduct a spectrally encoded three-dimensional (3D)(More)
BACKGROUND There is a paucity of information regarding pediatric dental emergencies in Taiwan. This study investigates the prevalence and characteristics of the pediatric dental emergency services provided at a medical center. METHODS This study included a retrospective chart review of patients under 18 years of age with dental complaints who visited the(More)
