Humoral Antibodies in Patients After Renal Homotransplantation.

Humoral antibodies have been demonstrated by antiglobulin consumption tests to be present in the serum of virtually all patients after renal homotransplantation. The most completely characterized was a γG immunoglobulin distinct from the Forssman antibody which reacts against sheep but not against human red cell antigens, and which absorbs selectively against panels of human liver, kidney or white blood cells. This antibody appeared within a few days or weeks after transplantation, usually shortly after a rejection episode, and was more or less continuously detectable thereafter. The antibody was found in all of 10 patients studied during the first 4 post-transplant months, and in 13 of 14 patients tested from 4 months to more than 2 years after operation. Preliminary observations are included on another humoral antibody which does not react with sheep RBC stromata, but which can also be measured with a modified antiglobulin consumption test. The latter antibody was less commonly demonstrable, but it also exhibited specific absorption characteristics when tested against a panel of leukocytes obtained from volunteers. The implications of these findings are discussed in relation to the possible value of such sera for histocompatibility typing, as well as the possible role of such antibodies in promoting homograft enhancement

Visualization of pilot flame of an optically-accessible coaxially-staged aero-engine lean-burn fuel injector

[EN] The visualization of the pilot flame of a coaxially-staged aero-engine lean-burn fuel injector, not only downstream but also inside of the pilot nozzle, was successfully performed at realistic aero-engine conditions. Optical access toward the inside of the nozzle was achieved through the inner and outer shrouds, both of which were made of transparent quartz. The image distortion caused by complex contours of the two shrouds was corrected by a method based on optical ray tracing, which realized precise determination of spatial intensity distribution of optical signals. Line-of-sight OH chemiluminescence, cross-sectional OH-LIF, kerosene LIF and kerosene Mie scattering were employed as diagnostic tools. The effects of pilot local air-to-fuel ratio on spray flame structure were revealed, both inside and downstream of the pilot nozzle under stable combustions. As the pilot mixture got rich, the main reaction zone moved from inside of the pilot nozzle to the region near the injector lip downstream of the injector exit. The OH-LIF signal was detected near the central axis surrounded by the fuel spray. It was also observed near the back-step of the pilot nozzle for the rich cases. The experiments under combustion oscillation were also conducted and the correlation of phenomena inside and downstream of the pilot nozzle was captured. It was clarified that the reaction enhancement in the outer part of the lip vortex region was caused by the convection of rich mixture, which appeared near the pilot atomizer lip at 150~210deg earlier oscillation phase angle.Matsuura, K.; Uesaka, S.; Iwasaki, T.; Kurosawa, Y.; Yamada, H.; Yamamoto, T.; Hayashi, S.

A functional genomics tool for the Pacific bluefin tuna: Development of a 44K oligonucleotide microarray from whole-genome sequencing data for global transcriptome analysis

AbstractBluefin tunas are one of the most important fishery resources worldwide. Because of high market values, bluefin tuna farming has been rapidly growing during recent years. At present, the most common form of the tuna farming is based on the stocking of wild-caught fish. Therefore, concerns have been raised about the negative impact of the tuna farming on wild stocks. Recently, the Pacific bluefin tuna (PBT), Thunnus orientalis, has succeeded in completing the reproduction cycle under aquaculture conditions, but production bottlenecks remain to be solved because of very little biological information on bluefin tunas. Functional genomics approaches promise to rapidly increase our knowledge on biological processes in the bluefin tuna. Here, we describe the development of the first 44K PBT oligonucleotide microarray (oligo-array), based on whole-genome shotgun (WGS) sequencing and large-scale expressed sequence tags (ESTs) data. In addition, we also introduce an initial 44K PBT oligo-array experiment using in vitro grown peripheral blood leukocytes (PBLs) stimulated with immunostimulants such as lipopolysaccharide (LPS: a cell wall component of Gram-negative bacteria) or polyinosinic:polycytidylic acid (poly I:C: a synthetic mimic of viral infection). This pilot 44K PBT oligo-array analysis successfully addressed distinct immune processes between LPS- and poly I:C- stimulated PBLs. Thus, we expect that this oligo-array will provide an excellent opportunity to analyze global gene expression profiles for a better understanding of diseases and stress, as well as for reproduction, development and influence of nutrition on tuna aquaculture production

Interaksi Masyarakat Keturunan Arab dengan Masyarakat Setempat di Pekalongan

Dalam penelitian ini penulis mengeksplorasi interaksi antara masyarakat keturunan Arab dengan masyarakat setempat di Kelurahan Klego Kota Pekalongan serta mengetahui faktor pendorong dan penghambat terjadinya interaksi antara masyarakat keturunan Arab dengan masyarakat setempat. Penelitian ini menggunakan metode kualitatif. Teknik pengumpulan data melalui metode wawancara, observasi, dan dokumentasi. Hasil penelitian menunjukan bahwa terjadi interaksi antara masyarakat keturunan Arab dengan masyarakat setempat dengan intensitas dan kegiatan kebudayaan tertentu. Faktor pendukung terjadinya interaksi adalah adanya perkawinan campuran, terutama pada masyarakat keturunan Arab non-sayyid, dengan masyarakat setempat serta adanya kerjasama dalam bidang perdagangan. Sedangkan faktor penghambat terjadinya proses interaksi adalah adanya prasangka dan stereotip pada masyarakat keturunan Arab yang merasa masyarakat setempat kurang Islami, sebaliknya masyarakat setempat merasa masyarakat keturunan Arab itu sombong. Keturunan Arab yang tinggal di Kelurahan Klego terdiri dari golongan sayyid dan golongan non-sayyid. Keturunan Arab dari golongan non-sayyid sudah dapat berbaur dengan masyarakat setempat sedangkan keturunan Arab dari golongan sayyid belum berbaur dengan masyarakat non-Arab. Masyarakat keturunan Arab memiliki simbol-simbol seperti bahasa, pakaian, bangunan yang sangat mempengaruhi interaksi antara masyarakat keturunan Arab dengan masyarakat setempat. In this study, the author explores the interaction between people of Arab descent and the local people in the village of Klego Pekalongan city and also the factors that drive and inhibit the interaction between them. This study uses qualitative methods. The technique of collecting data are interviews, observation, and documentation. The results show that there is a pattern of interaction between people of Arab descent with the local people. Factors supporting the occurrence of interactions are the presence of mixed marriages, especially in the Arab non-sayyid descent, with the local community as well as the cooperation in the field of trade. While the factors inhibiting the interaction process is the existence of prejudice and stereotypes of people of Arab descent at a local community as less Islami. On the other hand, the local people feel that people of Arab descent are exclusive. The Arab descent living in the Village Klego consists of groups and classes of non-sayyid and sayyid. Arab descent from the class of non-sayyid are able to mingle with the local people, whereas Arab descent of sayyid cannot mingle with non-Arab communities. Society of Arab descent has symbols such as language, clothing, and building that strongly influence the interaction of people of Arab descent with the local community

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
