Huang, Yong,Tong, Dedi,Zhu, Shan,Wu, Lehao,Mao, Qi,Ibrahim, Zuhaib,Lee, W. P. Andrew,Brandacher, Gerald,Kang, Jin U. Williams & Wilkins 2015 Plastic and reconstructive surgery Vol.135 No.4
BACKGROUND:: Evolution in microsurgical techniques and tools has paved the way for supermicrosurgical anastomoses, with vessel diameters often approaching below 0.8 mm in the clinical realm and even smaller (0.2 to 0.3 mm) in murine models. Several imaging and monitoring devices have been introduced for postoperative monitoring, but intraoperative guidance, assessment, and predictability have remained limited to binocular optical microscopy and the surgeon’s experience. The authors present a high-resolution, real-time, three-dimensional imaging modality for intraoperative evaluation of luminal narrowing, thrombus formation, and flow alterations. METHODS:: An imaging modality that provides immediate, in-depth, high-resolution, three-dimensional structure view and flow information of the anastomosed site, called phase-resolved Doppler optical coherence tomography, was developed. Twenty-two mouse femoral artery anastomoses and 17 mouse venous anastomoses were performed and evaluated. Flow status, vessel inner lumen three-dimensional structure, and early thrombus detection were analyzed based on imaging results. Predictions formed correlated with actual long-term surgical outcomes. Eventually, four cases of mouse orthotopic limb transplantation were carried out, and predicted long-term patency based on imaging results was confirmed by actual results. RESULTS:: The assessments based on high-resolution three-dimensional visualization of the vessel flow status and inner lumen provided by phase-resolved Doppler optical coherence tomography show 92 percent sensitivity and 90 percent specificity for arterial anastomoses and 90 percent sensitivity and 86 percent specificity for venous anastomoses. CONCLUSIONS:: Phase-resolved Doppler optical coherence tomography is an effective evaluation tool for microvascular anastomosis. It can predict the long-term vessel patency with high sensitivity and specificity.
Planet Versions of the State of Schr¨odinger’s Cat Prepared by Using Quantum Measurements
Yong-Yi Huang 한국물리학회 2016 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.68 No.8
A classical charged particle travels along a circular orbit and interacts with a silver atom in its ground state fixed at the center of the circle through Biot-Savart coupling. We find that if the silver atom initially lies in a spin superposition state of valence electron, in the co-rotating frame of reference the projected measurements of the spin of silver’s valence electron along the z direction determine the rotational direction, and the projected measurements of that spin along the x or the y direction yield planet versions of the state of Schr¨odinger’s cat.

C-doped BiVO4 with self-heterostructure were synthesized via a facile one-step microwave-hydrothermal route at different reaction temperatures and reaction times. The crystal structure,morphology and photophysical properties of the samples were characterized by X-ray diffraction (XRD), field-emission scanning electron microscope (FE-SEM) and UV-Vis techniques. The photocatalytic properties of the samples were evaluated by the decolorization of rhodamine B under ultraviolet light or simulated visible light irradiation. It was found that pure BiVO4 polyhedrons had a monoclinic structure while C-doped BiVO4 had self-heterostructure with both monoclinic and tetragonal phase. This mixed-phase structure exhibited higher activity than monoclinic structure under ultraviolet light irradiation while monoclinic C-doped BiVO4 had better photocatalytic property under simulated visible light irradiation. The selectivity of the light source with different C-doped BiVO4 self-heterostructures was also discussed in this work.

Yong Huang,Ke Yu,Ziqiang Zhu 한국물리학회 2007 Current Applied Physics Vol.7 No.6
a low temperature of 500.C. The patterned ZnO nanorod arrays, a unit area is of. 400 · 100 l m2, are synthesized via vapor phase trans-port method. The surface morphology and composition of the as-synthesized ZnO nanorods are characterized by means of scanningelectron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX). The mechanism of formation of ZnO nanorods is alsol m at the current density of 0.1l A/cm2 and a low threshold eld of 6.2 V/l m at the current density of 1 mA/cm2. So this approach musthave a potential application of fabricating micropatterned oxide thin lms used in FE-based at panel displays.
Quantitative Assessment the Relationship between p21 rs1059234 Polymorphism and Cancer Risk
Huang, Yong-Sheng,Fan, Qian-Qian,Li, Chuang,Nie, Meng,Quan, Hong-Yang,Wang, Lin Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.10
p21 is a cyclin-dependent kinase inhibitor, which can arrest cell proliferation and serve as a tumor suppressor. Though many studies were published to assess the relationship between p21 rs1059234 polymorphism and various cancer risks, there was no definite conclusion on this association. To derive a more precise quantitative assessment of the relationship, a large scale meta-analysis of 5,963 cases and 8,405 controls from 16 eligible published case-control studies was performed. Our analysis suggested that rs1059234 was not associated with the integral cancer risk for both dominant model [(T/T+C/T) vs C/C, OR=1.00, 95% CI: 0.84-1.18] and recessive model [T/T vs (C/C+C/T), OR=1.03, 95% CI: 0.93-1.15)]. However, further stratified analysis showed rs1059234 was greatly associated with the risk of squamous cell carcinoma of head and neck (SCCHN). Thus, larger scale primary studies are still required to further evaluate the interaction of p21 rs1059234 polymorphism and cancer risk in specific cancer subtypes.
Giant Ganglioneuroma of Thoracic Spine : A Case Report and Review of Literature
Huang, Yong,Liu, Lidi,Li, Qiao,Zhang, Shaokun The Korean Neurosurgical Society 2017 Journal of Korean neurosurgical society Vol.60 No.3
Ganglioneuroma (GN) is a rare benign tumor of neural crest origin usually found in the abdomen, but may occasionally present at uncommon sites including the cervical, lumbar, or sacral spine. However, GNs of thoracic spine are extremely rare. In this report, we describe a 12-year-old girl with giant GN in the thoracic spine, who underwent successful resection (T1-4 level) of the tumor. Histopathological examination confirmed the diagnosis. GN should be considered in the differential diagnosis of any paraspinal mass. A high index of suspicion and correlation of clinico-radiological findings is necessary in differentiating a large benign tumor from a malignant growth. Complete surgical excision is the treatment of choice; however tumor size and location need to be considered for the surgical approach (one-step or multiple surgeries). Close follow-up after surgery is mandatory.

MicroRNAs (miRNAs) are endogenous non-coding genes that participate in post-transcription regulation by either degrading mRNA or blocking its translation. It is considered to be very important in regulating insect development and metamorphosis. Insects are the largest group of animals and are extremely valuable in biological and agriculture research. Insects are also important pests to human health and agriculture, and efforts are necessary protect both humans and plants from disease and damage. Despite their importance, insects lag behind mammals, nematodes, and plants in miRNA research. At present, only 279 insect miRNAs have been identified from Drosophila melanogaster, Anopheles gambiae, Apis mellifera, Bombyx mori, and D. pseudoobscura in miRBase, and most of these miRNAs were computationally predicted without experimental validation. Functional analysis of insect miRNAs has only been conducted in D. melanogaster.

We propose a simplest detector of harmonic vibrations with micro amplitudes and low frequencies,i.e. a detector consisting of one atomic beam. Here, the atomic beam is induced by a plane harmonicwave and has classical collective harmonic vibrations, whose vibrant directions are perpendicularto the wave vectors of the atomic beam. Compared with a detector consisting of an atomic Mach-Zehnder interferometer, the new detector has two advantages: (1) it is suitable for the detection ofharmonic vibrations induced either by a longitudinal plane harmonic wave or by using a transverseplane harmonic wave: (2) the quantum noise fluctuation of the atomic beam is exactly zero. Wepresent the principle for detecting classical harmonic vibrations with micro amplitudes and lowfrequencies by using the new detector. The frequency of a classical harmonic vibration with a microamplitude can be evaluated by measuring the variations in the mean numbers of atoms arriving atthe atomic detector.
Reliable Mobility Evaluation of Organic Field-Effect Transistors With Different Contact Metals
Huang, Fanming,Liu, Ao,Zhu, Huihui,Xu, Yong,Balestra, Francis,Ghibaudo, Gerard,Noh, Yong-Young,Chu, Junhao,Li, Wenwu IEEE 2019 IEEE electron device letters Vol.40 No.4
<P>The reliability of mobility evaluation of organic field-effect transistors (OFETs) is a serious issue because numerous overestimated and underestimated mobilities have been reported recently. A reliable approach to accurately evaluate the OFET mobility is therefore highly desirable. Here, in this letter, two commonly employed methods and the Y function method (YFM) were used to extract the mobilities of indacenodithiophene-co-benzothiadiazole (IDT-BT) OFETs with four different contact metals. The mobilities extracted by the commonly used methods varied greatly with the contact metal and channel length, whereas those extracted by the YFM were very stable and approached the intrinsic mobility of IDT-BT. Our results show that YFM is a precise approach that can be widely used to evaluate the OFET mobility.</P>
