Lin, W.,Byrne, T.B.,Kinoshita, M.,McNeill, L.C.,Chang, C.,Lewis, J.C.,Yamamoto, Y.,Saffer, D.M.,Casey Moore, J.,Wu, H.Y.,Tsuji, T.,Yamada, Y.,Conin, M.,Saito, S.,Ito, T.,Tobin, H.J.,Kimura, G.,Kanagaw Elsevier Scientific Publishing Co 2016 Tectonophysics Vol.692 No.2

<P>To better understand the distribution of three dimensional stress states in the Nankai subduction zone, southwest Japan, we review various stress-related investigations carried out in the first and second stage expeditions of the Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE) by the Integrated Ocean Drilling Program (IODP) and compile the stress data. Overall, the maximum principal stress sigma(l) in the shallower levels (<similar to 1 km) is vertical from near the center of forearc basin to near the trench and; the maximum horizontal stress S-Hmax (interpreted to be the intermediate principal stress sigma(2)) is generally parallel to the plate convergence vector. The exception to this generalization occurs along the shelf edge of the Nankai margin where S-Hmax, is along strike rather than parallel to the plate convergence vector. Reorientation of the principal stresses at deeper levels (e.g., >similar to 1 km below seafloor or in underlying accretionary prism) with sigma(1) becoming horizontal is also suggested at all deeper drilling sites. We also make a comparison of the stress state in the hanging wall of the frontal plate-interface between Site C0066 in the Nankai and Site C0019 in the Japan Trench subduction zone drilled after the 2011 Mw 9.0 Tohoku-Oki earthquake. In the Japan Trench, a comparison between stress state before and after the 2011 mega-earthquake shows that the stress changed from compression before the earthquake to extension after the earthquake. As a result of the comparison between the Nankai Trough and Japan Trench, a similar current stress state with trench parallel extension was recognized at both C0006 and C0019 sites. Hypothetically, this may indicate that in Nankai Trough it is still in an early stage of the interseismic cycle of a great earthquake which occurs on the decollement and propagates to the toe (around site C0006).

1972年 7月 1日부터 1973年 6月 30日까지 1年間 中華民國 臺?省 金門鳥에서 絲狀 症에 關한 調査硏究를 實施한 바 다음과 같은 結果를 얻었다. 1. 金門鳥 55村落에 居住하는 20,018 住民을 對象으로 調査한 바 血中 microfilariae (mf.) 兩性率은 8.8%였고 血液 20立方mm當 mf농도는 16.2였으며 絲狀 感染으로 因 臨床例 는 19.2%였다. 金門鳥 駐屯 軍人 2,428名에서 mf.양성율은 0.1%, mf. 감염농도는 20立方mm當 26.3이었으며 臨床例는 없었다. mf.感染濃度 및 臨床例에 있어 확실히 女性보다는 男性에서 高率을 보였으나 mf.陽性率은 兩性間에 差異가 없었다. mf.陽性率과 臨床例는 年齡의 增加와 一致하였으나 mf. 감렴농도는 年齡의 증가와 無關하였다. 2. 金文鳥 駐屯 軍人에 있어 주둔 其間과 絲狀 感染과는 關係가 없었으며 駐屯基地와 村落과의 距離와도 無關하였다. 軍人들은 모기에 물리지 않도록 잘 保護되어 있었고 주둔지역은 完全히 住民들과 격리되어 있었다. 3. 51村落으로부터의 血液檢査를 받은 1,470名의 絲狀 感染陽性者 中에서 臨床病勢르 보인 例는 19.2%였으며 女性보다는 男性에서 約 5倍가 많았다. 男性에 있어서의 大部分의 臨床例는 生殖器에 症狀을 보였는데 其中 10%는 象皮症을 가진 例는 2名뿐이었다. 4. 43村落의 家屋內에서 잡힌 모기는 4屬 14種(Culex 10種, Aedes 2種, Anopheles 1種, Armigeres 1種)이었으며 이들中 Cules P. fatigans와 Armigeres subalbatus가 大部分이었으나 其他 12種은 매우 적었다. Culcx mimesticus, C. (L) vorax, C. fuscocephala 및 Acdes nocturnus등 의 4新種은 처음으로 發見되었다. Culex p.fatigans는 現存「반크롭트」 絲狀 만을 옮기는 媒介昆 으로 알려져 있다. 治療前 8個 村落으로부터 잡은 438마리의 Culex p. fatigans에서 幼 을 內包하고 있는 모기는 1마리 平均 5.9마리의 絲狀 幼 을 갖고 있는 셈이었으며 全體 感染率은 11.9%, 感染期 幼 을 가진 모기는 10.5%이었다. 上記 8個 村落 住民을 治癒한 後의 樣狀은 治療前과 아주 달라서 모기 1마리當 平均 2.1마리의 幼 을 갖고 있었고 全體感染率은 2.2%, 感染期幼 內包率은 0.09%였다. 平均 pH가 7.4(6.4∼8.0)인 8個處의 모기 産卵場所에서 잡힌 모기 幼 은 모두 11種이었다. 有機燐劑의 一種인 Sumithion을 1平方m當 0.2gm의 농도로 모기 産卵場所 水面에 撒布하였던바 모든 모기 幼 에 對한 殺 果가 좋았다. 5. 總 1.590名의 絲狀 感染者에게 成人當 總量 5gm의 diethylcarbamazine을 10∼12日 間 服用시켜 보았다. 治療率은 80.6%, mf. 減少率은 96.9%였고 反應率는 67.2%였다. 여러 가지 副作用은 있었으나 一般的으로 輕微하였으며 患者가 참을 수 있었으므로 最高用量으로 投藥했을 경우에도 大部分 거절 하지 않았다. 8個 部落에서 捕獲된 Culex P. fatigans의 絲狀 幼 全體感染率, 感染期幼 內包率 및 感染濃度는 患者治療前에 各各 11.9%, 10.5%, 5.9였는데 治療後에는 2.2%, 0.09%, 2.1로 떨어져서 diethylcarbamazine은 microfilariae에 對한 殺충효果가 높을 뿐 아니라 絲狀충 만延을 組止시키는데 좋은 藥劑라고 思料된다 The present investigation is a serial study on “Filariasis in Kinmen (Quemoy) Islands”, which was performed from July 1, 1972 to June 30, 1973. The results are summarized as follows; 1. Parasitological investigation: Of 20,018 Kinmen Chinese in 55 villages examined, the microfilariae (mf.) rate of 8.8%, mf. density of 16.2 per 20cmm blood and clinical rate 19.2% were found: the corresponding figures for a total of 2,428 military personnel were 0.1%, 29.3 and 0.0% respectively. The mf. density and clinical rate were obviously higher in the males than in the females, but no difference was found for the microfilarial rate. The mf. rate and clinical rate were correspondingly increased with age, but there was no difference in mf. density. 2. Transmission of filariasis: It seems no any relation to the length of stationing of the Chinese troops on Kinmen Islands, and also no relation to the distance between the villages and camps; because the servicemen are well protected from the mosquito bites and bites and the camps are completely isolated, to and off limit to the villagers, though they have common places of entertainment. 3. Clinical investigation: Of 1,470 filarial carriers in 51 villages examined physically, the clinical rate of 19.2% was detected. It was about 5 times higher in males than in females. In the males, most of the cases the trouble in their reproductive organs, and 10% had elephantiasis; but in the females, the lymph nodes enlargement and chyluria were more common, only 2 cases had elephantiasis. The clinical rates increased corresponding with age. 4. Entomological investigation: Fourteen(14) species of 4 genera (10 Culex, 2 Aedes, 1 Anopheles and 1 Armigeres) of household mosquitoes were collected from indoor resting sites of 43 villages on kinmen Islands, in which, Cules P. fatigans and Armigeres subalbatus were the most common species, but the remaining 12 species are faily rare. Four (4) new species: Culex mimeticus, C. (L) vorax, C, fucocephala and Aedes noturnvs were found for the first time. Culex p.fatigans is still the only vector. in transmission of bancroftian filariasis. The infection rate of 11.9%, infective rate of 10.5% and 5.9 filarial larvae per infected mosquito were detected in 438 Culex p. fatigans from 8 villages before treatment. The corresponding figures were much lower in the above same villages after treatment (2.2%, 0.09% and 2.1). Eleven (11) species of moswquito larvae were collected from 8 kinds of breeding sites; where, the pH value of 7.4(ranged 6.4∼8.0) was measured. “Sumithion”is one of the organophosphorous compounds, which was first used on the water surface with the dosage of 0.2gm per square meter.A high insecticidal effect against different species of mosquito larvae was observed. 5. Chemotherapy of filariasis: Of 1.590 filarial carriers scheme, with a total does of 5 gm of diethylcarbamazine per adult case for a period of 10∼12 days schedule was performed. The cure rate of 80.6%, mf. reduction tate of 96.9% and reaction rate of 67.2% were found. Although many kinds of side effects were encountered, they were usually mild or transient and could be tolerated by the patients, thus there was almost no refused to the administration of the drug even if the drug was increased to the maximum dosage. The natural infection rate, infective rate and filarial larval density of Culex P. fatigans in 8 villages were found much higher before control measure (11.9%, 10.5% and 5.9%) than after control (2.2%, 0.09% and 2.1). It showed that diethylcarbamazine is a powerful microfilaricidal drug in eliminating the filarial infection and reducing this transmission.

Various optical measurement technologies have ben used to characterize ZnMnO thin filmswith different Mn compositions grown by molecular beam epitaxy(MBE) on c-Al2O3 substrates. Thelat- tice constant and the crystalization quality have ben evaluated by using X-ray diraction (XRD). Photoluminescence (PL) has ben used to reveal the neutral-donor-bound exciton (D0X) and to checkthelm'squality. Defect-relatedabsorptionsignatures,inadditiontonear-band-edgeabsorp- tion, due to the zinc vacancy and the donor-aceptor pair (DAP) have ben found in the surface photovoltagespectra(SPS).Freexcitonictransitionsandtheirphonon-asistedreplicashaveben observed in the re ectance spectra. Our experimental results not only unveil specic optical tran- sitionenergies but also indicate arapid materiald deterioration whenMn incorporation goes beyond a certain amount to cause manganese segregation.

A novel small-molecule PPI inhibitor targeting integrin α_vβ₃-osteopontin interface blocks bone resorption in vitro and prevents bone loss in mice

Park, D.,Park, C.W.,Choi, Y.,Lin, J.,Seo, D.H.,Kim, H.S.,Lee, S.Y.,Kang, I.C. IPC Science and Technology Press 2016 Biomaterials Vol.98 No.-

<P>Small molecule-inhibition targeting protein-protein interaction (PPI) is now recognized as an emerging and challenging area in drug design. We developed a novel interactive drug discovery methodology known as Protein Chip technology (ProteoChip) as a cutting-edge PPI assay system applicable for unique PPI-targeting therapeutics integrated with computer-aided drug design (CADD). Here, we describe a novel small molecular PPI inhibitor, IPS-02001, which the blocks integrin alpha(v)beta(3)-osteopontin interface a novel PPI inhibitor identified by the interactive methodology of both ProteoChip- and CADD-based PPI assay. IPS-02001 (6,7-Dichloro-2,3,5,8-tetrahydroxy-1,4-naphthoquinone) was screened from different compound libraries (InterBioScreen, Commercial libraries) using an in silica structure-based molecular docking simulation method and a protein chip-based protein-protein interaction assay system. Additionally, integrin alpha(v)beta(3), an adhesion receptor expressed in osteoclasts (OCs), was implicated in the regulation of OC function via regulation of the cytoskeletal organization of OCs. IPS-02001 blocked OC maturation from murine bone marrow-derived macrophages, as well as the resorptive function of OCs. Moreover, treatment with IPS-02001 impaired downstream signaling of integrin alpha(v)beta(3) linked to Pyk2, c-Src, PLC gamma 2, and Vav3 and disrupted the actin cytoskeleton in mature OCs. Furthermore, IPS-02001 blocked RANKL-induced bone destruction by reducing the number of OCs and protected against ovariectomy-induced bone loss in mice. Thus, IPS-02001 may represent a promising new class of anti-resorptive drugs for treatment of bone diseases associated with increased OC function. (C) 2016 Elsevier Ltd. All rights reserved.</P>

Genetic polymorphism in pvmdr1 and pvcrt-o genes in relation to in vitro drug susceptibility of Plasmodium vivax isolates from malaria-endemic countries

Lu, F.,Lim, C.S.,Nam, D.H.,Kim, K.,Lin, K.,Kim, T.S.,Lee, H.W.,Chen, J.H.,Wang, Y.,Sattabongkot, J.,Han, E.T. Verlag für Recht und Gesellschaft ; Elsevier 2011 Acta Tropica Vol.117 No.2

Treatment failure of chloroquine for Plasmodium vivax infection has increased in endemic countries. However, the molecular mechanisms for resistance and in vitro susceptibility of P. vivax to chloroquine remain elusive. We investigated the prevalence of mutations in the pvmdr1 and pvcrt-o genes, and the copy number of the pvmdr1 gene in isolates from the Republic of Korea (ROK), Thailand, the Union of Myanmar (Myanmar), and Papua New Guinea (PNG). We also measured in vitro susceptibility of Korean isolates to antimalarial drugs. The pvmdr1 analysis showed that mutations at amino acid position Y976F of pvmdr1 were found in isolates from Thailand (17.9%), Myanmar (13.3%), and PNG (100%), but none from the ROK, and mutation at position F1076L was present in isolates from the ROK (100%), Thailand (60.7%), and Myanmar (46.7%). One copy of the pvmdr1 gene was observed in most isolates and double copy numbers of the gene were observed in two Thai isolates. In the exons of the pvcrt-o gene that were sequenced, a K10 insertion was present in isolates from Thailand (56.0%) and Myanmar (46.2%), and the wild type was found in all Korean isolates. The results suggest that gene polymorphisms and copy number variation was observed in isolates of P. vivax from Southeast Asian countries. In Korean isolates polymorphism as limited to the F1076L variant, and no isolates with high level of resistance were found by in vitro susceptibility determinations. Moreover, our results provide a baseline for future prospective drug studies in malaria-endemic areas.

A Study on the Plasma Biochemical Indices of Heat-Stressed Broilers

Lin, H.,Du, R.,Gu, X.H.,Li, F.C.,Zhang, Z.Y. Asian Australasian Association of Animal Productio 2000 Animal Bioscience Vol.13 No.9

Four experiments were conducted to evaluate the effect of temperature and humidity on biochemical indices of Arbor Acres broilers at different weeks of age. The alkaline phosphatase (AKP), acid phosphatase (ACP), lactic dehydrogenase (LD), creatine kinase (CK), plasma glucose (Glu), calcium (Ca), potassium (K), chloride (Cl), urea nitrogen (UN), uric acid (UA), plasma thyroxin (T4), triiodothyronine (T3) and insulin levels were determined in all the four experiments. In experiment 1, the plasma Glu, LD and CK levels were increased by heat exposure ($35{^{\circ}C}$ and 35, 60, or 85% RH, 2 h) and this effect was aggravated by longer exposure (24 h). No significant changes (p>0.05) were found in Ca concentration, activity of AKP and ACP. In experiment 2, temperature (10, 20, 30, $33{^{\circ}C}$) had significant effect on the levels of K, Cl, UN, UA levels and the activity of LD (p<0.01), but had no significant influence on the activity of CK (p>0.05). The UN, UK and LD levels were elevated by low temperature $(10{^{\circ}C})$ (p<0.01), Cl content was increased by high temperature ($(33{^{\circ}C})$ (p<0.01), and K level was decreased by high ($(33{^{\circ}C})$ or low $(10{^{\circ}C})$ temperature and increased by medium temperature $(30{^{\circ}C})$ (p<0.01). The humidity (35, 85% RH) only had significant effect on Cl concentration which was decreased by high humidity (p<0.01). In experiment 3, the result showed that only the LD and CK activity were significantly increased (p<0.01) by high temperature (7, 24, 28, $32{^{\circ}C}$) or high humidity (35, 85% RH). Temperature and humidity had no significant effect on K, Cl, UA, UN and Glu levels (p>0.05). In experiment 4 (24, 27, 30, $33{^{\circ}C}$; 30, 45, 60, 75, 90% RH), plasma T3 level was declined by high temperature $(33{^{\circ}C})$, and this phenomena disappeared in birds under high temperature and high humidity environment. T4 concentration in plasma was not affected by temperature (p>0.05), but was increased by high or low humidity (p<0.01). Neither temperature nor humidity had significant effect on plasma insulin concentration (p>0.05). The results of the four experiments suggested that broilers at different growth periods might have different thermal requirements and would response differently to heat exposure. The plasma biochemical indices themselves had big variation; the reaction of the indices to thermal exposure treatment differed with the age of broilers. The big variation of biochemical indices themselves might cover the response of indices to temperature and humidity treatments.

Applications of Laser-Fabricated Plasma Structures in Laser-Wakefield Accelerators, X-ray Lasers and Plasma Nonlinear Optics

C.T. Hsieh,M.W. Lin,C.L. Chang,Y.C. Ho,S.Y. Chen,J. Wang,M.C. Chou,J.Y. Lin,C.H. Pai,P.H. Lin,L.C. Tai,S.H. Chen,G.Y. Tsaur,C.C. Kuo,T.Y. Chien 한국물리학회 2008 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.53 No.6

A general method for fabricating transient plasma structures with high-intensity laser pulses is developed to gain fine control over laser-plasma interactions. These structures have been used as programmable photonic devices in the development of laser-wakefield accelerators, soft X-ray lasers and plasma nonlinear optics driven by multi-terawatt laser pulses. Plasma ramps are used to control electron injection in laser-wakefield accelerators, plasma waveguides are used to enhance the efficiency of soft X-ray lasers by orders of magnitude and periodic plasma structures are used to achieve quasi-phase matching in relativistic harmonic generation. By scanning the interaction length with the same plasma-fabrication method, tomographic measurements are carried out to resolve the injection/acceleration process in laser-wakefield accelerators and amplification processes in X-ray lasers and relativistic harmonic generation. A theoretical analysis and a computer simulation are also carried out to provide insightful pictures of these processes. These research works show that by controlling plasma structures with optical fabrication methods, laser-plasma interaction can be engineered to expand and enrich the frontier of high-field physics.

DISCOVERY OF X-RAY PULSATIONS FROM THE NEXT GEMINGA, PSR J1836+5925

Lin, L. C. C.,Hui, C. Y.,Li, K. T.,Takata, J.,Hu, C. P.,Kong, A. K. H.,Yen, D. C. C.,Chou, Y. IOP Publishing 2014 ASTROPHYSICAL JOURNAL LETTERS - Vol.793 No.1

<P>We report recent XMM-Newton investigations of PSR J1836+5925, the 'next Geminga,' which determined an X-ray pulsation of similar to 173.3 ms. Its X-ray periodicity is consistent with the gamma-ray ephemeris at the same epoch. The X-ray folded light curve has a sinusoidal structure that is different from the double-peaked gamma-ray pulse profile. We have also analyzed the X-ray phase-averaged spectra which shows that the X-ray emission from PSR J1836+5925 is thermal dominant. This suggests that the X-ray pulsation mainly originates from the modulated hot spot on the stellar surface.</P>
