Xiang-Hong Fang,Fang Fang,Chun-Hai Lu,Lei Zheng 한국원자력학회 2017 Nuclear Engineering and Technology Vol.49 No.3

Serving as an excellent adsorbent and inorganic ion exchanger in the water purification field, zeolite 4A has in this work presented a strong capability for purifying radioactive waste, such as Sr2+, Csþ, and Co2+ in water. During the processes of decontamination and decommissioning of suspended solids and organics in low-level radioactive wastewater, the purification performance of zeolite 4A has been studied. Under ambient temperature and neutral condition, zeolite 4A absorbed simulated radionuclides such as Sr2+, Csþ, and Co2+ with an absorption rate of almost 90%. Additionally, in alkaline condition, the adsorption percentage even approached 98.7%. After conducting research on suspended solids and organics of zeolite 4A for the treatment of radionuclides, it was found that the suspended clay was conducive to absorption, whereas the absorption of organics in solution was determined by the species of radionuclides and organics. Therefore, zeolite 4A has considerable potential in the treatment of radioactive wastewater.

Acute Flaccid Myelitis: Current Status and Diagnostic Challenges

Xiang Fang,Ruksana Huda 대한신경과학회 2020 Journal of Clinical Neurology Vol.16 No.3

Acute flaccid myelitis (AFM) is a sudden-onset polio-like neuromuscular disability found commonly in young children. There is an increasing incidence of confirmed AFM cases in the USA and other countries in recent years, and in association with nonpolio enterovirus infection. This represents a significant challenge to clinicians and causes significant concern to the general public. Acute flaccid paralysis (AFP) is the long-known limb paralytic syndrome caused by a viral pathogen. AFM is a subset of AFP that is also characterized by a limb paralytic condition, but it has certain distinct features such as lesions in magnetic resonance imaging of the spinal cord gray matter. AFM leads to spinal cord, brainstem, or motor neuron dysfunction. The clinical phenotypes, pathology, and patient presentation of AFM closely mimic AFP. This article provides a concise overview of our current understanding of AFM and the clinical features that distinguish AFM from AFP and similar other neurological infectious and autoimmune diseases or disorders. We also discuss the diagnosis, clinical pathology, possible pathogenetic mechanisms, and currently available therapies.

The fruiting body pattern is an important agronomic trait of the edible fungus Auricularia auricula-judae, and an important breeding target. There are two types of fruiting body pattern: the cluster type and the chrysanthemum type. We identified the fruiting body pattern of 26 test strains, and then constructed two different near-isogenic pools. Then, we developed sequence characterized amplified region (SCAR) molecular markers associated with the fruiting body pattern based on sequence-related amplified polymorphism (SRAP) markers. Ten different bands (189-522 bp) were amplified using 153 pairs of SRAP primers. The SCAR marker “SCL-18” consisted of a single 522-bp band amplified from the cluster-type strains, but not the chrysanthemum strains. This SCAR marker was closely associated with the cluster- type fruiting body trait of A. auricula-judae. These results lay the foundation for further research to locate and clone genes controlling the fruiting body pattern of A. auricula-judae.

Fang Shen,Wan-li Huang,Bao-ping Xing,Xiang Fang,Mei Feng,Chun-ming Jiang 대한신경정신의학회 2018 PSYCHIATRY INVESTIGATION Vol.15 No.11

Objective Recent studies have indicated the possibility that genistein may improve depression via regulating the expression of miR- 221/222. This study is to explore whether genistein could improve depression by altering miR-221/222 levels and investigate the possible mechanisms involved in the improvement effect of genistein. Methods The animal model of depression was established through unpredictable chronic mild stress. Nest building test and splash test were adapted to evaluate the effects of genistein on depressive symptoms in mice. qRT-PCR and western blot analysis were used to detect the expression of miR-221/222 and connexin 43 (Cx43) in the prefrontal cortex of the mice. In vitro, U87-MG astrocytes were treated with genistein and the expression of miR-221/222 and Cx43 was measured. The dual-luciferase reporter assay was used to verify whether Cx43 was a direct target of miR-221/222. Results The behavioral tests showed that genistein could significantly reduce depression symptoms of mice, and this remission was not affected by gender. Genistein in vivo and in vitro could reduce increased levels of miR-221 and miR-222 in the prefrontal cortex of depressed mice, while upregulate Cx43 expression. Dual-luciferase reporter assay suggested Cx43 was directly regulated by miR-221/222 in astrocytes. Conclusion Genistein can play its antidepressant effect through down-regulating miR-221/222 by targeting Cx43.

Forming a thick CdZnTe epitaxial film by sublimating closely spaced

Xiang-Xiang Luoa,Cheng-Fang Qiao,Simon R Hall,Chun-Sheng Zhou 한양대학교 청정에너지연구소 2023 Journal of Ceramic Processing Research Vol.24 No.6

Thick Cadmium zinc telluride epitaxial films were grown on (100)GaAs substrate by Close-Spaced Sublimation. The growthrate was around 1 μm/min. SEM observations and XRD θ-2θ scan and ф scan revealed well-defined epitaxial features ofthe films. The films were found to be polycrystalline at the early stage of growth. As growth progressed, the films graduallybecame oriented until an epitaxial layer was formed. The polycrystalline to monocrystalline transition was achieved bypreferential lateral growth of the grains and with the aid of migration of atoms in the film. This growth mode differs fromthe well-established epitaxy where a suitable lattice fit is expected from the early stages of film growth. This mode can betterguide the growth mode of CZT thick films, and can grow large volume and high-quality thick films. High quality thick filmscan be better applied in fields such as solar cells, infrared and ultraviolet detection, and X-ray detection.

이핵 화합물, $Ag_2$[Phen]_2[S_2P(OPr)_2]_2$(Phen=1,10-phenanthroline; Pr=propyl)은 비스(디프로필디싸이오포스페이토) 은(|)화합물과 1,10 펜안트로린 리간드 반응에 의하여 합성되었고, 그 화합물 구조는 X-ray에 의하여 규명되었다. 두 디프로필디싸이오포스페이토 리간드는 두 개의 은 원자를 연결하여 팔각형 $Ag_2S_4P_2$ 고리를 형성하였고, 1,10-펜안트로린 리간드는 은 이온과 결합하여 사면체구조를 이루었다. Ag-S 결합거리는 2.471(1)와 2.567(1) ${\AA}$이었고, Ag-N 결합 거리는 2.3666(3)와 2.471(3) ${\AA}$이었다. The dinuclear $Ag_2[Phen]_2[S_2P(OPr)_2]_2$(phen=1,10-phenanthroline; Pr=propyl), was prepared by the reaction of bis(dipropyldithiophosphato) silver(I) complex with 1,10-phenanthroline ligand, and its structure was determined by X-ray crystallography. The two dipropyldithiophosphato ligands each bridge two silver atoms to form an eight-membered $Ag_2S_4P_2$ ring, while the 1,10-phenanthroline molecule coordinates to a silver atom to complete the local tetrahedral geometry for the metal ion. The Ag-S bond distances are 2.559(1) and 2.567(1)${\AA}$, and the Ag-N bond distances are 2.366(3) and 2.471(3)${\AA}$.

Dong Fang,Zheng Hu-Zhe,Jeong Woo-Sik,Chung Shin-Kyo,Qu Zhong-Yuan,Zou Xiang,Liu Chen,Xiang Qiong,Feng Feng 한국응용생명화학회 2021 Applied Biological Chemistry (Appl Biol Chem) Vol.64 No.S

In order to obtain and explore selenide composed of selenium and polysaccharide, three parameters were selected to optimize the synthesis process of selenium-Euryale ferox Salisb. polysaccharide (Se-ESPS) by Box-Behnken design. Furthermore, ESPS-B1 separated from ESPS was selenitized to Se-ESPS-B1 by the optimal synthesis process, then the characterization, and antioxidant activity in vitro of Se-ESPS-B1 were explored. The result manifested that the Se content of Se-ESPS was (2.915 ± 0.03) mg/g according to the optimal synthesis process of Se-ESPS (reaction time at 5 h, reaction temperature at 81 ℃, weight ratio of Na2SeO3 to ESPS at 0.9 g/g). A series of detection results indicated that the characterizations of Se-ESPS-B1 were apparently distinguished from that of ESPS-B1. Moreover, the antioxidant experiments in vitro demonstrated that Se-ESPS-B1 could exert antioxidant activity by scavenging DPPH, ABTS,·OH, and increasing reduction ability. In conclusion, the synthesis process is an effective approach to harvest seleniumpolysaccharide, and Se-ESPS-B1 may be utilized as a potential antioxidant or selenium nutritional supplement.

중국 조선족의 상장례 풍속 연구 -중국 흑룡강성(黑龍江省) 제제합이시(薺薺哈爾市)를 중심으로-

방향옥 ( Xiang Yu Fang ) 동양예학회 2010 東洋 禮學 Vol.23 No.-

본고는 필자의 거주지인 중국의 헤이룽장성(黑龍江省) 치치하얼시(齊齊哈爾市)를 중심으로, 현대 중국 조선족의 상장례의 세시풍속 및 그 절차와 방법을 살펴보고 전통 한국과의 상장례 차이를 중국 정책과 관련지어 밝혀보고자 한데 그 목적이 있다. 상장례 절차는 임종(臨終), 초혼(招魂), 발상(發喪)·부고(訃告), 수시(收屍)·습염(襲殮), 발인(發靷), 장례의식(葬禮儀式) 등 여섯 부분으로 구분하여 농촌과 도시를 중심으로 살펴보고 상장례의 특징을 다음의 여덟 가지로 정리하였다. 첫째, 시신의 머리 부분을 문 방향으로 놓는다. 둘째, 사잣밥을 놓는 풍속이 예전부터 없다. 셋째, 시신을 담은 관이 창문으로 나갈 때 창문 위에 사발을 엎어 놓고 세 번 두드려 깬다. 넷째, 이 지역 조선족의 상장례가 현대에 이르러 극히 간소화 되어 나타났다. 이것은 중국의 정책의 변화와 중국 공산당의 무신론 사상의 주입과 직접 관련된다. 다섯째, 이 지역에서 실시 하고 있는 화장(火葬)과 장례의식이 특이하다. 전통적인 매장(埋葬)이 현대에는 의무적으로 화장(火葬)으로 바뀌었고 장례의식은 반드시 지정된 장소에서 규정된 격식에 맞추어 치러야 하는데 이것은 중국 정부의 환경보호 정책, 토지 절약 정책, 유물론의 관념과 직접 관련된다. 여섯째, 시신과 영좌를 분리하여 둔다. 시신을 빈소에 두고 집에다 다시 영좌를 세워 조석(朝夕)으로 전(奠)을 올린다. 일곱째. 이 지역에 대렴(大殮)의 절차가 생략되어 나타났다. 여덟째, 치치할 시의 조선족은 집에서도 조문을 받고 장례식장에서도 조문을 받는 이중적 성격을 띤다. This thesis is to search for the manners of funeral rites of modern ethnic Koreans living in Qiqihar city, Heilongjiang province, China and the procedures and methods, and to reveal the difference with traditional Korean funeral rites, related with Chinese policy. I divided the procedure of funeral rites into six parts such as death, rite calling the soul of dead person, telling death to others, correcting the position and cleaning of corpse, putting corpse into coffin, and funeral rite in rural and urban areas, and summarized eight characteristics of funeral rites as the following. The first step is to put the head part of corpse to the direction of door. Secondly, there has been no manners which put the food table for dead person from old days. Thirdly, when the coffin containing corpse goes out, a person breaks the turned bowl which was put after beating it three times. Thirdly, the funeral rite of modern ethnic Koreans living in this locality has been very simplified. This is directly related with the change of Chinese policy and the infusion of atheistic thought of Chinese Communist Party. Fifthly, the cremation and funeral rite in this area are unique. The traditional burial has been changed into the obligatory cremation in modern age and the funeral rite should be carried out in the designated place according to the defined funeral rules, which is directly related with environment protection policy, land sparing policy, and materialism of the Chinese government. Sixthly, the corpse is put in the place separated with the place of putting mortuary tablet. The family puts the corpse in the mortuary and set up the mortuary tablet in the house again, and give ancestral rite every morning and evening. Seventhly, the procedure of binding the corpse with line and putting it into coffin on the third day is omitted in this area. Eighthly, modern ethnic Koreans living in China receive condolence in both the house and the funeral hall, which has the dualistic character.
