<P>The magnetic properties of polycrystalline ceramic samples (Nd1-xYx)(0.7)Sr0.3MnO3 with x = 0.21 - 0.35 were studied by means of dc magnetization and ac susceptibility measurements. Experimental results reveal a strong decrease of the ferromagnetic (FM)-paramagnetic phase-transition temperature (T-C) from 97 to 65 K as increasing x from 0.21 to 0.35, respectively. There is magnetic inhomogeneity associated with short-range FM order. Particularly, the samples undergo a spin-glass (SG) phase transition at the so-called blocking temperature (T-B) below T-C, which shifts toward lower temperatures with increasing the applied field, Hex; T-B -> T-g (the SG phase-transition temperature) as H-ex -> 0. The existence of the SG behavior in these samples was also confirmed by frequency (f) dependences of the ac susceptibility. For the in-phase/real component, chi' (T), it shows a frequency-dependent peak at the SG freezing temperature (T-f); T-f -> T-g as f -> 0. Dynamics of this process were analyzed by means of the slowing down scaling law, tau/tau(0) proportional to (T-f/T-g - 1)(-zv), where tau(0) and zv are the characteristic time and critical exponent, respectively. Fitting the experimental T-f(f) data to the scaling law gave the results of zv = 10.1-12.3 and tau(0) = 10(-21)-10(-15)s. These values are different from those expected for canonical SG systems with zv = 10 and tau(0) = 10(-13)s, revealing the cluster-SG behavior of (Nd1-xYx)(0.7)Sr0.3MnO3 samples. Notably, the increase in Y content leads to the shift of tau(0) and zv values toward those of canonical SG systems, which is ascribed to an expansion of SG clusters.</P>

임신 및 각종 갑상선질환에서 갑상선 기능 판정에 관한 연구 : 혈청유리 T4의 진단적 의의에 관한 고찰 The diagnostic value of free thyroxine by RIA

이종철,유명희,윤휘중,신영태,정순일,조보연,이문호,이명철 대한핵의학회 1981 핵의학 분자영상 Vol.15 No.1

To evaluate the diagnostic accuracy of the measurement of free thyroxine(FT4) by radioimmunoassay, we measured free T4 and T4, T3, T3RU, TSH and TBG serum levels by radioimmunoassay in 18 healthy persons and 52 patients with various thyroid diseases and 11 normal pregnant women. The results are as follows. 1) In 19 cases of overt hyperthyroidism, T3, free T4 and FTI, T4/TBG ratio reflect hyperfunction in all cases. T4 is increased in 94%(18/19) and TBG and TSH are decreased in 79%(15/19). 2) In 8 patients with overt hypothyroidism, TSH is increased in all cases and free T4 and FTI is decreased in all cases. T4 is decreased in 87.5%(7/8), T3 is decreased in 75%(6/8) and T4/TBG ratio is decreased in 62.5%(5/8). 3) In 5 patients who are clinically in euthyroid state after treatment of hyperthyroidism, T4 free T4, FTI and TSH are in the normal range in all cases and T3 is normal in 60%(3/5) and slightly increased in 40%(2/5). 4) In 10 patients who showed clinically borderline hypothyroidism after treatment of hyperthyroidism, TSH is increased in all cases and free T4 and FTI are decreased in all cases, but T4 and T3, T4/TBG ratio are in the normal limit in all cases. So after treatment of hyperthyroidism, TSH, free T4 or FTI are recommended as optimal function test. 5) In normal pregnancy, free T4, FTI and T4/TBG ratio reflect normal function, but the other parameters unreliable due to the influence of increased TBG. Also TBG and TSH level in pregnancy is increased significantly compared with normal healthy control group. 6) The coefficients of correlation between T4 and FTI were 0.862(p〈0.001) and 0.685(p〈0.001) between free T4 and T4/TBG ratio. In most patients, diagnostic value of free T4 was comparable and even superior to FTI, so free T4 measurement can be used routinely with thyrotropin assay in the diagnosis of hypothyrodism or with T3 for the diagnosis of hyperthyroidism.

Two-stage partial melting and contrasting cooling history within the Higher Himalayan Crystalline Sequence in the far-eastern Nepal Himalaya

Imayama, T.,Takeshita, T.,Yi, K.,Cho, D.L.,Kitajima, K.,Tsutsumi, Y.,Kayama, M.,Nishido, H.,Okumura, T.,Yagi, K.,Itaya, T.,Sano, Y. Universitetsforlaget ; Elsevier Science Ltd 2012 Lithos Vol.134 No.-

The timing of partial melting and the pressure-temperature (P-T) paths in the High Himalayan Crystalline Sequence (HHCS) in far-eastern Nepal has been investigated using zircon chronology, rare earth element (REE) compositions, and P-T pseudosection analysis. Zircon from migmatites formed during Himalayan thermal events displays inherited magmatic core overgrown by two generations of metamorphic rims. The new rims are distinguished on the basis of their Tertiary ages, low MREE contents, and low Th/U ratios. The inner zircon rims from Sil+Grt+Bt+Kfs+Pl+Qtz and Ky+Sil+Grt+Bt+Ms+Pl+Qtz migmatites at different structural level of the HHCS display ages of c. 33-28Ma (Early Oligocene) and c. 21-18Ma (Early Miocene): these rims are characterized by flat MREE to HREE patterns and were overgrown by partial melt through muscovite dehydration melting under the stability of garnet, which occurred at P=c. 7-10kbar and T=c. 730-780<SUP>o</SUP>C, and at P=c. 8-14kbar and T=c. 720-770<SUP>o</SUP>C, respectively. The outer zircon rims are relatively enriched in HREE with respect to the inner rims and were overgrown at c. 27-23Ma (Late Oligocene) and at c. 18-16Ma (Early Miocene) during melt crystallization accompanying breakdown of garnet at P=c. 4-7kbar and T=c. 650-725<SUP>o</SUP>C. Early Miocene Ms-Bt leucogranites with two successively overgrown zircon rims at c. 18.3+/-0.3Ma and c. 16.3+/-0.2Ma were intruded into Early Oligocene migmatite hosts. Microstructural observations and the corresponding P-T conditions associated with the two generations of zircon rims indicate that the Early Oligocene and Early Miocene migmatites show relatively isobaric and nearly isothermal P-T paths during exhumation, respectively. The inferences are consistent with higher average cooling rates for the Early Miocene (c. 30-40<SUP>o</SUP>C/My) than the Early Oligocene (c. 15-25<SUP>o</SUP>C/My) migmatites, inferred from peak-T conditions and FT (c. 6Ma for both migmatites) and U-Pb zircon ages. The P-T-t paths of the two migmatites indicate that burial of the Early Miocene migmatites has been coeval with exhumation of the Early Oligocene migmatites, implying the formation of large-scale thrust within the HHCS.

Thanh, T.D.,Nan, W.Z.,Nam, G.,Van, H.T.,You, T.S.,Phan, T.L.,Yu, S.C. Elsevier 2015 CURRENT APPLIED PHYSICS Vol.15 No.10

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.

Ngo, Hien T. T.,Kook, MooChang,Yi, Tae-Hoo International Union of Microbiological Societies 2015 International journal of systematic and evolutiona Vol.65 No.3

<P>A Gram-stain-negative, strictly aerobic, rod-shaped and pinkish-yellow bacterium, which was motile by gliding and designated strain THG–T11<SUP>T</SUP>, was isolated from tomato rhizosphere soil in Gyeonggi province, Republic of Korea. Based on 16S rRNA gene sequence comparisons, strain THG-T11<SUP>T</SUP> was found to be most closely related to ‘Pedobacter <I>zeaxanthinifaciens</I>’ TDMA-5 (95.9 % sequence similarity), <I>Pedobacter agri</I> PB92<SUP>T</SUP> (94.9 %), <I>Pedobacter rhizosphaerae</I> 01-96<SUP>T</SUP> (94.6 %) and <I>Pedobacter alluvionis</I> NWER-II11<SUP>T</SUP> (94.5 %). The DNA G+C content was 38.4 mol%. The only isoprenoid quinone detected in strain THG-T11<SUP>T</SUP> was menaquinone-7 (MK-7). The major component in the polyamine pattern was <I>sym</I>-homospermidine. The major polar lipids were phosphatidylethanolamine, an unidentified phosphoglycolipid, an unidentified glycolipid, an unidentified lipid, unidentified aminophospholipids and unidentified aminolipids. The major ceramide was found to be ceramide phosphorylethanolamine. The major fatty acids were identified as iso-C<SUB>15 : 0</SUB>, summed feature 3 (C<SUB>16 : 1</SUB>ω7<I>c</I> and/or C<SUB>16 : 1</SUB>ω6<I>c</I>) and C<SUB>16 : 0</SUB>. These data support the affiliation of strain THG-T11<SUP>T</SUP> to the genus <I>Pedobacter</I>. Based on phenotypic, chemotaxonomic and phylogenetic analysis, it is proposed that strain THG-T11<SUP>T</SUP> represents a novel species of the genus <I>Pedobacter</I> for which the name <I>Pedobacter</I> <I>ureilyticus</I> sp. nov. is proposed, with THG-T11<SUP>T</SUP> as the type strain ( = KACC 17660<SUP>T</SUP> = JCM 19461<SUP>T</SUP>).</P>

Relative Genetic Effects of Duroc and Taoyuan Breeds on the Economic Traits of Their Hybrids

Yen, N.T.,Tai, C.,Cheng, Y.S.,Huang, M.C. Asian Australasian Association of Animal Productio 2001 Animal Bioscience Vol.14 No.4

For determining the relative genetic effects of Duroc (D) and Taoyuan (T) breeds on the economic traits of their hybrids, 72 litters of pigs, from four mating types, namely TT (T♂$\times$T♀), DD (D♂$\times$D♀) and D-T hybrids (TD, T♂$\times$D♀ and DT, D♂$\times$T♀) were used in this study. The various crossbreeding parameters were estimated by comparisons among mating types using linear contrasts of least-square analysis. The results of reproductive traits analysis showed that T breed had contributed superior genetic effects on the total number of piglets at birth (TBN) (p<0.10) and number of live piglets at 21 days (LP21) (p<0.05) to the D-T hybrids. Estimates of maternal genetic effects showed that the T females were superior in TBN (p<0.05), but inferior in average birth weight (ABW) and average litter birth weight (LBW) (p<0.01) to the D females. Direct heterosis effects were significant for LBW, LP21 and LWT21 (p<0.01). Least-squares analysis of other economic traits showed that T breed had relative negative effects on all growth traits, withers height (WH), body type index (BTI), average backfat thickness (ABF), carcass length (LENG), loin eye area (longissimus) (LEARA), and lean percentage (LEAN) of D-T hybrids (p<0.05). Estimates of direct genetic effects showed that the D breed was superior to the T breed in all growth and carcass traits except the average backfat (BF). Estimates of maternal genetic effects showed that average body weight at 180 days (WT180) of progenies from T sows were lighter than from D sows. Progenies from D females had larger and leaner carcass than those from T females. Direct heterosis effects were significant for average daily weight gains from 150 to 180 days ($ADG_{150-180}$) (p<0.05) and for average body weights at 150 (WT150), and 180 days (WT180), average daily weight gains from birth to 150 and 180 days ($ADG_{150}$ and $ADG_{180}$, respectively), WH, body length (BL), ABF, BTI, and LENG (p<0.01). The results showed that D-T hybrids tended to have superior TBN and LP21 than D breed, and to be superior in all growth and most conformation and carcass traits to the T breed.

Survival of tissue-resident memory T cells requires exogenous lipid uptake and metabolism

Pan, Youdong,Tian, Tian,Park, Chang Ook,Lofftus, Serena Y.,Mei, Shenglin,Liu, Xing,Luo, Chi,O’Malley, John T.,Gehad, Ahmed,Teague, Jessica E.,Divito, Sherrie J.,Fuhlbrigge, Robert,Puigserver, Pere,Kru Macmillan Publishers Limited, part of Springer Nat 2017 Nature Vol.543 No.7644

Tissue-resident memory T (T<SUB>RM</SUB>) cells persist indefinitely in epithelial barrier tissues and protect the host against pathogens. However, the biological pathways that enable the long-term survival of T<SUB>RM</SUB> cells are obscure. Here we show that mouse CD8<SUP>+</SUP> T<SUB>RM</SUB> cells generated by viral infection of the skin differentially express high levels of several molecules that mediate lipid uptake and intracellular transport, including fatty-acid-binding proteins 4 and 5 (FABP4 and FABP5). We further show that T-cell-specific deficiency of Fabp4 and Fabp5 (Fabp4/Fabp5) impairs exogenous free fatty acid (FFA) uptake by CD8<SUP>+</SUP> T<SUB>RM</SUB> cells and greatly reduces their long-term survival in vivo, while having no effect on the survival of central memory T (T<SUB>CM</SUB>) cells in lymph nodes. In vitro, CD8<SUP>+</SUP> T<SUB>RM</SUB> cells, but not CD8<SUP>+</SUP> T<SUB>CM</SUB> cells, demonstrated increased mitochondrial oxidative metabolism in the presence of exogenous FFAs; this increase was not seen in Fabp4/Fabp5 double-knockout CD8<SUP>+</SUP> T<SUB>RM</SUB> cells. The persistence of CD8<SUP>+</SUP> T<SUB>RM</SUB> cells in the skin was strongly diminished by inhibition of mitochondrial FFA β-oxidation in vivo. Moreover, skin CD8<SUP>+</SUP> T<SUB>RM</SUB> cells that lacked Fabp4/Fabp5 were less effective at protecting mice from cutaneous viral infection, and lung Fabp4/Fabp5 double-knockout CD8<SUP>+</SUP> T<SUB>RM</SUB> cells generated by skin vaccinia virus (VACV) infection were less effective at protecting mice from a lethal pulmonary challenge with VACV. Consistent with the mouse data, increased FABP4 and FABP5 expression and enhanced extracellular FFA uptake were also demonstrated in human CD8<SUP>+</SUP> T<SUB>RM</SUB> cells in normal and psoriatic skin. These results suggest that FABP4 and FABP5 have a critical role in the maintenance, longevity and function of CD8<SUP>+</SUP> T<SUB>RM</SUB> cells, and suggest that CD8<SUP>+</SUP> T<SUB>RM</SUB> cells use exogenous FFAs and their oxidative metabolism to persist in tissue and to mediate protective immunity.
