<P>Deletion of the HSP110 T-17 mononucleotide repeat has recently been identified as a prognostic marker that is correlated with wild-type HSP110 (HSP110wt) expression in microsatellite instability-high (MSI-H) colorectal cancers. The aim of this study was to assess the correlation between deletion of the HSP110 T-17 repeat and expression of HSP110wt using DNA testing and immunohistochemistry and to determine the prognostic implications of HSP110 T-17 deletion in MSI-H advanced gastric cancers (GCs). The status of HSP110wt expression was evaluated by immunohistochemistry using an HSP110wt-specific antibody in 142 MSI-H advanced GCs. The size of the HSP110 T-17 repeat deletion was analyzed in 96 MSI-H advanced GCs; deletions were divided into small (0-2 base pairs) and large deletions (3-5 base pairs). Low and high expressions of HSP110wt were detected in 38 (26.8%) and 104 (73.2%) of the 142 cases, respectively. The HSP110 T-17 deletion was observed in 45 (46.9%) of the 96 MSI-H GC samples. Tumors with high expression of HSP110wt showed a tendency to have small or no deletion of HSP110 T-17. In Kaplan-Meier survival analysis, tumors with a large HSP110 T-17 deletion were associated with favorable overall survival and disease-free survival compared with those with small/no deletion of HSP110 T-17. However, HSP110 T-17 deletion size was not an independent prognostic factor in multivariate analysis. In summary, deletion of the HSP110 T-17 repeat was frequently observed in MSI-H GCs, and HSP110 T-17 deletion size was inversely correlated with HSP110wt expression status. Large HSP110 T-17 was not a prognostic indicator in MSI-H GCs. (C) 2017 Elsevier Inc. All rights reserved.</P>

This study was made to evaluate the nutritional values and glucosinolate contents of three types of rapeseed oil meal(RSM), originated from Canada(canola), China(CRSM:Chinese Rapeseed Oil Meal) and India (IRSM:Indian Rapeseed Oil Meal), and their dietary effects on the performance of weanling pigs. Nutritional evaluation included the contents of moisture, crude protein(CP), ether extracts (EE), crude fiber(CF), Ash, Ca and P, KOH solubility, tannin, and glucosinolate contents of each RSM. Total of two hundred-forty weanling pigs weighing about 20㎏ initially were housed in 24 pens with 10 pigs per pen. The thirty animals were assigned to one of eight rations : T₁ (0% RSM + 2% molasses), T₂ (6% canola + 2% molasses), T₃ (6% CRSM + 2% Molasses), T₄(6% IRSM + 2% molasses), T_5 (0% RSM + 5% molasses), T_6 (6% Canola + 5% molasses). T_7 (6% CRSM + 5% molasses), T_8 (6% IRSM + 5% molasses). During the experimental period, body weight and feed intakes were measured weekly and feed conversion rates were calculated. The results obtained from this experiments are summarized as follows. 1. The KOH solubility of canola, CRSM and IRSM was found to be 54.6, 35.7 and 64.8%, respectively. The glucosinolate contents of canola, CRSM and IRSM were found to be 0.11, 0.22 and 0.79%, respectively. 2. There were no significant differences between the 2% molasses and the 5% molasses supplemented groups in feed intake and body weight gain. 3. The 6% CRSM(T₃, T_7) and IRSM(T₄, T_8) groups were significantly (P$lt;0.05) inferior to the control groups(T₁, T_5) and 6% canola groups(T₂, T_6) in feed intake and body weight gains. The control groups(T₂, T_6) were significantly (P$lt;0.05) superior to the 6% canola groups(T₂, T_6), 6% CRSM(T₃, T_7) and 6% IRSM groups(T₄, T_8) in feed conversion rate.

It is well known that normal pregnancy is accompanied by a rise in serum concentrations of thyroxine-binding globulin(TBG) and human chorionic gonadotropin (hCG). Alterations of biochemical parameters of thyroid function are recognized during gestation and sensitive tests to evaluate the alterations easily are required. Therefore, a cross-sectional study was undertaken in 140 healthy pregnant women to evaluate the efficacy of free T_4 measured by 2-step RIA compared to other thyroid function tests and to confirm the changes of thyroid function according to the stages of normal pregnancy. The sensitivities of free T_4 index, free T_4(by 2-step RIA), T_3 and TSH were realtively high(99.3%, 93.6%, 92.9%, 83.6%, respectively) compared to those of T_4 and T_3 bead upgake(49.3%, 21.4%) during all stages of pregnancy. There were positive correlations between free T_4 index and free T_4 or total T_4(r=0.68, r=0.72; p$lt;0.001). The values of free T_4 index sharply decreased from 3.22+-0.10(meam +-SEM) during 6th-12th week to an plateau after 16th-20th week of gestation(p$lt;0.01). The serum concentrations free T_4 and T_3 bead uptake also significantly decreased from 1.65+-0.05 ng/dl, 24.7+- 0.7% during 6th-12th week to an plateau after 16th-20th week of gestation, respectively(p$lt;0.001), No differences were found in the changes of serum concentrations of T_3, T_4 and TSH according to the stages of pregnancy. In conclusion, it is adequate to measure some tests including free T_4 index and free T_4 to evaluate thyroid function during pregnancy. The thyroid physiology and changes of thyroid function according to the stages of pregnancy should be considered in the interpretation of thyroid function status during pregnancy(J Kor Soc Endocrinol 9: 183-189, 1994).

A systematic study of the conventional and inverse magnetocaloric effects, and critical behaviors in an alloy ingot of Ni<SUB>43</SUB>Mn<SUB>46</SUB>Sn<SUB>8</SUB>In<SUB>3</SUB> has been performed. Our results reveal the sample exhibiting structural and magnetic phase transitions at temperatures T<SUB>C</SUB><SUP>M</SUP> = 166 K (T<SUB>C</SUB> of the martensitic phase), T<SUB>M-A</SUB> = 260 K (the martensitic-to-austenitic phase transformation) and T<SUB>C</SUB><SUP>A</SUP> = 296 K (T<SUB>C</SUB> of the austenitic phase). The large values of refrigerant capacity (RC) around T<SUB>M-A</SUB> and T<SUB>C</SUB><SUP>A</SUP> are found to be RC<SUB>M-A</SUB> = 172.6 and RC<SUB>A</SUB> = 155.9 J kg<SUP>-1</SUP>, respectively, under an applied field change of 30 kOe. Our critical analyses near the T<SUB>C</SUB><SUP>M</SUP> and T<SUB>C</SUB><SUP>A</SUP> reveal that a coexistence of the long- and short-range ferromagnetic order in the martensitic phase, while the long-range ferromagnetic order exists in the austenitic phase. Interestingly, at around T<SUB>C</SUB><SUP>A</SUP>, the maximum magnetic entropy change (|ΔS<SUB>max</SUB>|) versus magnetic field H obeys a power law, |ΔS<SUB>max</SUB>| = a.H<SUP>n</SUP>, where the exponent n is found to be about 0.66.

Toxoplasma gondii and Trichinella spiralis are important zoonotic pathogens with worldwide distributions. In Korea, several outbreaks of human toxoplasmosis and trichinellosis due to the consumption of infected wild animals have been reported. The purpose of this study was to determine the seroprevalence of T. gondii and T. spiralis infections in wild boars killed in Korea from December 2009 to October 2011. A total of 521 wild boars hunted in eight provinces were examined for antibodies to T. gondii and T. spiralis by using commercial ELISA kits. Overall, 25.1% of serum samples from individual boars were seropositive for T. gondii and 1.7% were seropositive for T. spiralis. Seropositive for T. gondii was found in the boars in all the eight provinces investigated and for T. spiralis in four provinces. This is the first report on the seroprevalence of T. gondii and T. spiralis infections in wild boars in Korea. The consumption of undercooked wild boar meat may expose humans to a high risk of infection.

<P>Measurements are presented of the t-channel single-top-quark production cross section in proton-proton collisions at root s = 8 TeV. The results are based on a data sample corresponding to an integrated luminosity of 19.7 fb(-1) recorded with the CMS detector at the LHC. The cross section is measured inclusively, as well as separately for top (t) and antitop (t) over bar, in final states with a muon or an electron. The measured inclusive t-channel cross section is sigma(t-ch.) = 83.6 +/- 2.3 (stat.) +/- 7.4 (syst.) pb. The single t and (t) cross sections are measured to be sigma(t-ch.)(t) = 53.8 +/- 1.5 (stat.) +/- 4.4 (syst.) pb and sigma(t-ch.)(t) over bar = 27.6 +/- 1.3 (stat.) +/- 3.7 (syst.) pb, respectively. The measured ratio of cross sections is Rt-ch. = sigma(t-ch.)(t)/sigma(t-ch.)(t) over bar = 1.95 +/- 0.10 (stat.) +/- 0.19 (syst.), in agreement with the standard model prediction. The modulus of the Cabibbo-Kobayashi-Maskawa matrix element V-tb is extracted and, in combination with a previous CMS result at root s = 7 TeV, a value vertical bar V-tb vertical bar = 0.998 +/- 0.038 (exp.) +/- 0.016 (theo.) is obtained.</P>

<P>We present a comprehensive view of the W51B H II region complex and the W51C supernova remnant (SNR) using new radio observations from the VLA, VLBA, MERLIN, JCMT, and CSO along with archival data from Spitzer, ROSAT, ASCA, and Chandra. Our VLA data include the first lambda = 400 cm (74 MHz) continuum image of W51 at high resolution (88 ''). The 400 cm image shows non-thermal emission surrounding the G49.2-0.3 H II region, and a compact source of non-thermal emission (W51B_NT) coincident with the previously-identified OH (1720 MHz) maser spots, non-thermal 21 and 90 cm emission, and a hard X-ray source. W51B_NT falls within the region of high likelihood for the position of TeV gamma-ray emission. Using the VLBA, three OH (1720 MHz) maser spots are detected in the vicinity of W51B_NT with sizes of 60-300 AU and Zeeman effect magnetic field strengths of 1.5-2.2 mG. The multiwavelength data demonstrate that the northern end of the W51B HII region complex has been partly enveloped by the advancing W51C SNR and this interaction explains the presence of W51B_NT and the OH masers. This interaction also appears in the thermal molecular gas which partially encircles W51B_NT and exhibits narrow pre-shock (Delta v similar to 5 km s(-1)) and broad post-shock (Delta v similar to 20 km s(-1)) velocity components. RADEX radiative transfer modeling of these two components yield physical conditions consistent with the passage of a non-dissociative C-type shock. Confirmation of the W51B/W51C interaction provides additional evidence in favor of this region being one of the best candidates for hadronic particle acceleration known thus far.</P>
