Postweaning multisystemic wasting syndrome (PMWS) was reproduced in prenatally porcine circovirus 2 (PCV2)-infected pigs by either postnatal infection with parvovirus (PPV) or immunostimulation. Twenty-four randomly selected piglets from 3 sows, which had been experimentally infected during gestation PCV2, were divided into groups; group 1 (prenatal PCV2 infection, PPV infection), keyhole limpet hemocyanin, emulsified incomplete Freund's adjuvant [KLH/ICFA] injection), and only). uninfected...
Muons have been accelerated by using a radio-frequency accelerator for the first time. Negative muonium atoms (${\mathrm{Mu}}^{\ensuremath{-}}$), which are bound states of positive muons (${\ensuremath{\mu}}^{+}$) and two electrons, generated from ${\ensuremath{\mu}}^{+}$'s through electron capture process in an aluminum degrader. The ${\mathrm{Mu}}^{\ensuremath{-}}$'s initially electrostatically injected into quadrupole linac (RFQ). In RFQ, to 89 keV. identified momentum measurement time...
Muon acceleration is an important technique in exploring the new frontier of physics. A measurement muon dipole moments planned J-PARC using linear accelerator. The low-energy (LE) source thin metal foil target and beam diagnostic system were developed for world's first acceleration. Negative muonium ions from as LE was successfully observed. Also profile positive measured by LE-dedicated monitor. test a Radio-Frequency Quadrupole linac (RFQ) being prepared step accelerator development. In...
The objective of this study was to determine the effect vaccination against classical swine fever virus (CSFV) on development postweaning multisystemic wasting syndrome (PMWS) in conventional pigs infected experimentally with porcine circovirus type 2 (PCV-2). PCV-2 and immunised modified live CSFV developed mild moderate PMWS, whereas none alone or PMWS. Lesions histologically characteristic PMWS were observed lymph nodes from vaccine, extensive replication detected by situ hybridisation.
천연 한약재인 금은화, 상엽, 황련(48.5 : 48.5 3.0)으로부터 얻은 복합 한약재 추출물 0.3%와 항생제(Albac G150) 0.05%를 육계에 각각 급여한 후 닭 가슴육과 다리육의 산화 안정성을 평가하였다. 추출물이나 항생제 모두 급여하지 않은 구를 대조구로 하였다. 닭가슴육의 총 페놀 함량은 급여구가 가장 높았고, 급여구 및 대조구의 순으로 나타났다. 전자 공여능은 급여구에 비해 닭다리육 0일차 저장에서 높게 나타났으며, <TEX>$ABTS^+$</TEX> radical 소거 활성 또한 높은 활성을 나타내었다. 저장 중 지방산패도는 일반적으로 처리구간 차이가 없었다. 실험결과 급여구나 대조구에 계육의 안정성에 효과적이었으며, 기능성 물질의 급여는 대체뿐만 아니라 부가적 기능의 향상 가능성도 기대할 수 있다고 본다. This study was evaluated the oxidative stability of breast and leg meat from...
Growing demand for embryo transfer is steadily expanding and further studies on in vitro fertilization of cattle. To assess the effect calcium lactate by replacing Tyrode's Albumin Lactate Pyruvate (TALP) medium composition during embryonic development.
The muon g−2/EDM experiment at J-PARC aims to measure the anomalous magnetic moment and electric dipole with high precision by utilising an ultracold beam. current g−2 discrepancy between Standard Model prediction experimental value is about 3.5 standard deviations. This requires a development of LINAC accelerate thermal muons 300 MeV/c momentum. Detectors for beam diagnostics play key role in such experiment. profile monitoring system has been designed low energy It was tested during two...
Maternal serum markers in 1st and 2nd trimesters are widely used for screening test of aneuploidy. Although demised fetus may affect the markers, vanishing twin (VT) is not considered as an adjustment factor risk assessment. The purpose this study was to evaluate effect VT on trimester maternal nuchal translucency (NT). This a secondary analysis multicenter prospective cohort study, which designed cost-effectiveness various prenatal strategies Down's syndrome. Pregnant women were enrolled 12...
A negative muonium ion (${\mathrm{Mu}}^{\ensuremath{-}}$) source using an aluminum foil target (Al target) was developed as a low-energy muon source. ${\mathrm{Mu}}^{\ensuremath{-}}$ ions are produced by irradiating the Al with 3-MeV positive (${\ensuremath{\mu}}^{+}$) beam and observed microchannel plate. An experiment to produce conducted evaluate performance of this The measured event rate $(1.7\ifmmode\pm\else\textpm\fi{}0.3)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}3}\text{...
The pathophysiology of non-immune hydrops is not well established and inadequate cardiac output or heart failure fetus has been hypothesized as one the mechanism to underlie abnormal fluid collection in hydrops. To examine this hypothesis, we analyzed N-terminal pro-B-type natriuretic peptide (NT pro-BNP) troponin T (cTnT) neonates, which are marker for myocardial damage pediatric adult patients. study population consisted singleton neonates with healthy control matched gestational age at...
The objective of this study is to determine the frequency and clinical significance intrauterine hematoma in immediate postpartum period. We prospectively enrolled singleton pregnant women who were delivered vaginally at near term/term (>33 weeks gestation). presence or absence was evaluated on 1st day by transabdominal ultrasound. A total 77 cases enrolled. There no evidence retained products conception (RPOC) none needed additional treatment for RPOC after delivery. present 86% (66/77) (65...
