It has been recognized that hyperthyroidism occur in patients with trophoblastic disease, either hydatidiform moles or choriocarcinomas. In the past decade, several lines of evidence have shown that human chorionic gonadotropin, secreted by the trophoblastic disease, is a thyroid stimulator and causes hyperthyroidism. In order to evaluate the relationship between level of thyroid hormone and human chorionic gonadotropin in patients with trophoblastic disease, level of thyroid hormone, serum -HCG and amount of urinary excretion of HCG were measured and analyzed in 24 patients with hydatidiform mole and 11 patients with choriocarcinoma who were admitted to Yonsei University Severance Hospital during the period from January 1981 to December 1986. The results are summarzed as follows: 1) Hyperthyroidism was observed in 33.3% of the patients with hydatidiform mole and in 18.2% of the patients with choriocarcinoma. 2) The amount of 24 hour urinary excretion of HCG in patients with hyperthyroidism was more than that in euthroid patients. 3) There was no difference in the level of thyroid hormone, serum -HCG, and amount of 24 hour urinary excretion of HCG in patients with hydatidifrom mole and choriocarcinoma. 4) The amount of 24 hour urinary excretion of HCG had significant correlation with FT4, whereas no similar correlation was observed between the levels of thyroid hormone and serum -HCG. In conclusion, the occurrence of hyperthyroidism is closely related with the amount of urinary excretion of HCG in patients with trophblastic disease.

In ship structure, the corner of the hatch opening on the main deck is one of the hot spot in the sense that stress concentration resulting in initiation of the fatigue crack damage is occured under the action of the repeated loading. In order to perform a more reliable design of ship structure, it is very important to carry out safety assessment on the basis of fatigue strength as well as bucking or ultimate strength. In this study, stress analysis of the corner of the main deck hatch opening for 30 actual ships in conducted by using FEM. Based on these results, stress concentration factor and fatigue life are predicted. It is observed from the result of this study that the stress concentration factor of the objective ships are ranged from 2.1 to 8.2 and fatigue life from 2 to 4 years in general.

<P></P> <P>This report presents the comparison philosophy, methodology, analysis and the results of the designed CCM.D-K4 key comparison that covered the calibration of high resolution hydrometers for liquid and alcoholometers in the density range 600 kg/m<SUP>3</SUP> to 2000 kg/m<SUP>3</SUP> at the temperature of 20°C. The main purpose of this comparison was not only to evaluate the degree of equivalence in the calibration of high accuracy hydrometers between NMI participants, but also to link, were it is possible, the results of previous comparisons to Key Comparison Reference Values (KCRVs) of CCM.D-K4. Eleven NMI laboratories took part in the CCM.D-K4 divided in two groups (petals).</P> <P>With the CCM.D-K4 purpose, two similar sets consisting of three hydrometers for liquid density determinations and an alcoholometer were circulated to the NMI participants as a travelling standard in the time interval from January 2011 to April 2012.</P> <P>Twelve Key Comparison Reference Values (KCRVs) for each petal have been obtained at the density values related to the tested density marks of the transfer standards by the results of participants. The KCRVs and corresponding uncertainties were calculated by the weighted mean in the case of consistent results, otherwise the median was used.</P> <P>The degree of equivalence (DoE) with respect to the corresponding KCRV was determined for each participant and, in this particular comparison, the Weighted Least Squares (WLS) method was used to link the individual DoE of each participant by a continuous function.</P> <P>Significant drift of the transfer standards was not detected.</P> <P>This report also gives instructions on calculating pair-wise degrees of equivalence, with the addition of any information on correlations that may be necessary to estimate more accurately as well as the procedure for linking international comparisons to the CCM.D-K4. Finally an example of linkage to the CCM.D-K4 is given by dealing with the results of the bilateral comparison between INRiM and NMIA, which was added to this comparison so that all participants were engaged after the breakage of the 9340171 artefact.</P> <P>A particularly good agreement was found among the results provided by most of the participants, even if some systematic differences and either underestimated or overestimated uncertainties of the submitted results can be identified with respect to the KCRVs. In general the deviations of the laboratory results to the KCRVs are within of 1/3rd to 1/4th of a scale division and the uncertainty at 95% is usually within half a division. During the analysis of the submitted results, a systematic difference between the first and last immersed mark was also noted, possibly due to a temperature gradient along the stem and/or wetting of the stem around the tested mark, and therefore a corrected claimed uncertainty from each laboratory is expected. However this comparison may help the laboratories to solve some residual or marginal problems as well as to better understand the uncertainty components.</P> <P>The comparison fully supports the calibration measurement capabilities table in the BIPM key comparison database (KCDB).

The goal of this work was to investigate the correlations between MyHC mRNA transcription and their corresponding protein expressions in porcine longissimus muscle (LM) during postnatal growth of pigs. Five DLY ($Duroc{\times}Landrace{\times}Yorkshire$) crossbred pigs were selected, slaughtered and sampled at postnatal 7, 30, 60, 120, and 180 days, respectively. Each muscle was subjected to quantity MyHCs protein contents through an indirect enzyme-linked immunosorbent assay (ELISA), to quantity myosin heavy-chains (MyHCs) mRNA abundances using real-time polymerase chain reaction. We calculated the proportion (%) of each MyHC to total of four MyHC for two levels, respectively. Moreover, the activities of several key energy metabolism enzymes were determined in LM. The result showed that mRNA transcription and protein expression of MyHC I, IIa, IIx and IIb in LM all presented some obvious changes with postnatal aging of pigs, especially at the early stage after birth, and their mRNA transcriptions were easy to be influenced than their protein expressions. The relative proportion of each MyHC mRNA was significantly positively related to that of its corresponding protein (p<0.01), and MyHC I mRNA proportion was positively correlated with creatine kinase (CK), succinate dehydrogenase (SDH), malate dehydrogenase (MDH) activities (p<0.05). These data suggested that MyHC mRNA transcription can be used to reflect MyHC expression, metabolism property and adaptive plasticity of porcine skeletal muscles, and MyHC mRNA composition could be a molecular index reflecting muscle fiber type characteristics.

Samples with a norminal composition of Bi1:6Pb0:4Sr2Ca2Cu3Oy were prepared by using the sol- gel method. The growth of high-Tc superconducting phases (Bi,Pb)2Sr2Can..1CunO2n+4δ (n = 1, 2 and 3) and their particle size were observed for increasing sintering temperature by using x-ray powder diraction and scanning electron microscopy. The superconductivity of the samples was obtained by using resistivity and ac-susceptibility measurements. The results showed the evident dependence of the superconducting transition characteristics on the particle size over a wide range from sub-micron to some tens of micrometers. The mixing on an atomic scale obtained by using the sol-gel method and the doped elements like Pb and Ag are the key technological elements that govern the growth rate of the high-Tc superconducting phases and their particle sizes.

Rice cultivation by direct seeding allows reduced labour and production costs in addition to other benefits. However the success of this rice production method can be limited by uneven fields with poor drainage or heavy rainfall at sowing leading to early flooding conditions slowing germination and hindering crop establishment. Hence, the need to improve tolerance to anaerobic conditions in both rainfed and irrigated rice ecosystem after direct seeding. In this study QTL analysis was performed to identify QTLs associated with tolerance derived from Vietnamese variety Tai Nguyen (TN) under anaerobic conditions during germination. The population derived from a cross between TN (tolerance indica lines) and Anda (susceptible japonica), was used for collection of phenotypic data based on the survival rates of the seedlings at 21 days after sowing under 10cm of water. A total of 286 F2:3 families of the population were used for QTL mapping and the genotyping was carried out with the infinium 6K SNP-chip based on the illumina infinium platform. Two significant QTLs associated with the AG trait were detected on chromosomes 1 and 11, respectively. In Particular, the QTL on chromsome 1 had an LOD score of 7.45 and R2 of 14.21%. We plan to confirm the identified QTLs in further studies and develop varieties with improved anaerobic germination ability using advanced backcross lines.
