Diagnostic usefulness of a T cell-based assay for latent tuberculosis infection in kidney transplant candidates before transplantation.Transpl Infect Dis 2010: <B>12:</B> 113–119. All rights reserved</P><P>Background</P><P>The presence of latent tuberculosis (TB) infection (LTBI) should be evaluated before kidney transplantation. Although a new T cell-based assay for diagnosing LTBI gave promising results, this assay has not yet been compared with the tuberculin skin test (TST) for diagnosing LTBI in renal transplant candidates before transplantation.</P><P>Patients and methods</P><P>All adult patients admitted to a single institute for renal transplantation over a 1-year period were prospectively enrolled. A clinically predictive risk of LTBI was defined as: (i) recent close contact with a person with pulmonary TB; (ii) abnormal chest radiography; (iii) a history of untreated or inadequately treated TB; or (iv) a new infection (i.e., a recent conversion of TST).</P><P>Results</P><P>Of 209 renal recipients, 47 (22%) had a positive TST≥5 mm, 21 (10%) had a positive TST≥10 mm, 65 (30%) had a positive T-SPOT.<I>TB</I> test, and 25 (12%) had an indeterminate T-SPOT.<I>TB</I> test. The induration size of TST was significantly associated with a high positivity rate on T-SPOT.<I>TB</I> (<I>P</I><0.001). Agreement between T-SPOT.<I>TB</I> test and TST≥10 mm was fair (<I>k</I>=0.24, 95% confidence interval 0.11–0.36). However, neither univariate nor multivariate analysis showed any association between the clinical risk for LTBI and positivity on T-SPOT.<I>TB</I> or TST.</P><P>Conclusion</P><P>T-SPOT.<I>TB</I> test was more frequently positive than TST in renal transplant candidates. However, further longitudinal studies are awaited to determine whether the ability of T-SPOT.<I>TB</I> assay to detect LTBI in renal transplant recipients can better predict the development of TB than can TST after transplantation.</P>

Effects of calcium doping on the superconducting properties of top-seeded melt growth processed Y_1.5Ba_2-xCa_xCu₃O_y superconductors

Park, S.D.,Kim, H.J.,Park, B.J.,Han, Y.H.,Jun, B.H.,Lee, J.S.,Kim, C.J. North-Holland 2011 Physica. C, Superconductivity Vol.471 No.21

The effect of calcium doping on the superconducting properties of top seeded melt growth (TSMG) processed Y<SUB>1.5</SUB>Ba<SUB>2-x</SUB>Ca<SUB>x</SUB>Cu<SUB>3</SUB>O<SUB>y</SUB> superconductors was studied in terms of calcium content (X<SUB>ca</SUB>). YBa<SUB>2-x</SUB>Ca<SUB>x</SUB>Cu<SUB>3</SUB>O<SUB>7-δ</SUB> (X<SUB>ca</SUB>=0, 0.005, 0.01, 0.02, 0.04, 0.1, 0.3) powders were synthesized by the powder calcination method. YBa<SUB>2-x</SUB>Ca<SUB>x</SUB>Cu<SUB>3</SUB>O<SUB>7-δ</SUB> powders were mixed with 0.25mole Y<SUB>2</SUB>O<SUB>3</SUB> powder and 1wt.% CeO<SUB>2</SUB> as Y<SUB>2</SUB>BaCuO<SUB>5</SUB> (Y211) refiner, and finally made into Y<SUB>1</SUB>.<SUB>5</SUB>Ba<SUB>2-x</SUB>Ca<SUB>x</SUB>Cu<SUB>3</SUB>O<SUB>y</SUB> (Y1.5)+1wt.% CeO<SUB>2</SUB> composition. The single Y123 growth on the top surface was observed up to X<SUB>ca</SUB>=0.1, while the multiple Y123 growth was observed at X<SUB>ca</SUB>≥0.1. The superconducting transition temperature (T<SUB>c</SUB>) and critical current density (J<SUB>c</SUB>) of TSMG processed Y1.5 samples were inversely proportional to X<SUB>ca</SUB>. The Y211 size increased with increasing X<SUB>ca</SUB> due to the enhancement of Y211 coarsening by calcium doping. No Y211 refining effect by CeO<SUB>2</SUB> was observed in the calcium doped samples. The T<SUB>c</SUB> and J<SUB>c</SUB> decrease by calcium doping are likely to be due to the calcium incorporation with the Y123 lattice and formation of coarse Y211 particles.

Antibiotic susceptibility and resistance of Streptococcus iniae and Streptococcus parauberis isolated from olive flounder (Paralichthys olivaceus)

Park, Y.K.,Nho, S.W.,Shin, G.W.,Park, S.B.,Jang, H.B.,Cha, I.S.,Ha, M.A.,Kim, Y.R.,Dalvi, R.S.,Kang, B.J.,Jung, T.S. Elsevier Scientific Pub. Co 2009 Veterinary microbiology Vol.136 No.1

The rates of antibiotic susceptibility and resistance were investigated in Streptococcus iniae and Streptococcus parauberis isolates obtained from diseased olive flounders (Paralichthys olivaceus) collected from fish farms in Jeju Island, Korea. Isolates of S. iniae (n=65) were susceptible to cefotaxime, erythromycin, ofloxacin, penicillin, tetracycline and vancomycin, as demonstrated by the minimum inhibitory concentration (MIC) test. Isolates of S. parauberis (n=86) were highly resistant to erythromycin (58% of the 86 isolates tested) and tetracycline (63% of the 86 isolates tested). Fifty-four isolates of tetracycline-resistant S. parauberis contained the tet(M/O/S) genes, of which 39 and 12 isolates contained the tet(M) and tet(S) genes, respectively, whereas 3 isolates contained both the tet(M) and tet(S) genes. Among the erythromycin-resistant isolates of S. parauberis (n=50) only 14 contained the erm(B) gene. These results suggest that the tet(S) and erm(B) genes of S. parauberis are involved in the acquisition of high-level resistance to erythromycin and tetracycline. Our findings reveal a high rate of antibiotic resistance among strains of S. parauberis and emphasize the need to develop an appropriate vaccine to reduce the use of antibiotics.

Y. J. KIM, J. G. JI, J. T. KIM, J. H. HONG, J. S. LEE, H. S. LEE, S. B. PARK. A comparison study for mask plantar pressure measures to the difference of shoes in 20 female. Korean Journal of Sport Biomechanics, Vol. 14, No. 3, pp. 83-98, 2004. The purpose of this study was to investigate the test-retest of plantar pressures using the F-Scan system over speeds and plantar regions. 6 healthy female subjects in 20's were recruited for the study. Plantar pressure measurements during locomotor activities can provide information concerning foot function, particularly if the timing and magnitude of the loading profile can be related to the location of specific foot structures such as the metatarsal heads. The Tekscan F-Scan system consists of a flexible, 0.18mm thick sole-shape having 1260 pressure sensors, the sensor insole was trimmed to fit the subjects' right. left shoes - sneakers shoes & dress shoes. It was calibrated by the known weight of the test subject standing on one foot. The Tekscan measurements show the insole pressure distribution as a function of the time. This finding has important implications for the development of plantar pressure test protocols where the function of the forefoot is important. According to the result of analysis it is as follows : 1) Center of force trajectory in women's dress shoes display direct movement, compare with center of force trajectory in Sneaker shoes displays a little bit curved slow pronation movement. Sneaker shoes in forefoot part display very quick supination movement, therefore, this shoes effects negative effectiveness for ankle's stability. Considering center of force trajectory analyzing, the more center of force close straight line, the more movement can be quick movement for locomotion. For foot pressure distribution, center of force trajectory in locomotion is better to curved trajectory with pronation movement. So sneaker shoes style is good shoes considering center of pressure distribution trajectory compare with women's dress shoes. 2) Women's dress shoes increased peak pressure in medial, this is effected by high hill's height. The more increased women's dress shoes's height, the more women's peak pressure will increase, pronation can increase compare with before. Supination movement increase, this focused pressure in lateral, also, supination increased more. If the supination movement increased, foot pressure focused in lateral, therefore, it is appeared force distribution in gait direction. This is bad movement in foot's stability. 3) Women's dress shoes in landing phase displayed a long time, this is when women's dress shoes wear, gait movement is unbalance, so, landing phase displayed a long time. For compensation in gait, swing phase quick movement. 4) Women's dress shoes displayed peak pressure distribution in lateral of rearfoot part, Sneakers shoes displayed peak pressure distribution in medial of forefoot part. Its results has good impact absorption compare with women's dress shoes. In forefoot part, sneakers shoes has good propulsive force compare with women's dress shoes.

Using Random Sampling, the authors measured the body heights and weights of 31,151 persons- 17,102 in males and 14,049 in females from metropolitan, urban and rural areas between 6 to over 80 year old - for the purpose of investigating the type and the actual condition of the Korean's growth and development. At first, on the basis of the results, the authors measured the growth and development, various kinds of physiques, nutritional index of the 6 to 20s age group. Second, the authors presented the standard body weight of males and females by their body height, who were in the end of their growth (20-29 age group). Third, the authors calculated and presented the normal adapted body weight of the age group who were over 30 age after the growth had been completed. Forth, the author presented the obesity rate of the adults over 20 years old by body mass index. Finally, the authors compared chronological change of the Koreans' body heights and body weights with the results of other researchers. 1. Body Measurement Rapid growth, in terms of body height, which is described by a straight line on a growth curve has been observed among males in the ages 6-13 and among females 6-14. That growth curve turned out to be slower among the people of higher ages by both sexes. The cross-over occurred in both sexes at 11-14. The highest growth rate for a year is at 13-16 for males and 11-13 for females. This indicates that females enter a rapidly growing stage 2 years earlier than males. 2. Various Physiques and Nutritional Index Rapid growth, in terms of Relative Body Weight Index, which is described by a straight line, has been observed among males in the ages 6-16 and females in the ages 6-14. The cross-over occurred in both sexes 12.5-14.5 age in the adolescencent period. Whereupon females outgrow males. The Roher Index displayed more good value in case of females than male and in the adolescent period, the level of fullness is lower than after the completion of development. The Kaup Indices of both sexes increase with age. The index is less than 2.0 for males in 6-14 age group and for females in 6-13 age group and with this, it appeared that development of horizontal axis to long axis is poor. The index is more than 2.0 after 15 age group in males and 14 age group in females and developmental state4 age group and for females in 6-13 age group and with this, it appeared that development of horizontal axis to long axis is poor. The index is more than 2.0 after 15 age group in males and 14 age group in females and developmental state. Body Mass Index is less than 20 for males 6-14 age group and for females in 6-13 age group. In the case of the higher age group, that index maintains a normal state. 3. Average Body Height, Body Weight and Desirable Body Weight of Korean Youth (20-29 Age Group) The average body weight and body height of full-grown Korean youth was 172.5 ± 5.4㎝ and 66.3 = 9.5㎏ for male, 159.3 ±4.6 ㎝ and 53.5 ±6.9 ㎏ for females. In the case of calculating Desirable Body Weight of Korean youth, correlation coefficient of r = + 0.38(p < 0.001)between body height and body weight was found the male group and r = + 0.37(p < 0.001) in the female group, from which respective linear regression equation of body weight and height was established for male and female as follows; Male : Y(Body Weight, ㎏) = 0.66 x (Body Height, ㎝) - 48.93 Female :Y(Body Weight, ㎏) = 0.56 x (Body Height, ㎝) - 36.01 4. Formulae for calculating Normal Adapted Body Weight of Korean Adult. ⅰ)Average body height and body weight by age-groups 30-39 age-group Male : 170.4 ±4.9㎝ and 67.6 ±8.1㎏ Female : 158.5 ±3.9㎝ and 53.6 ±6.0㎏ 40-49 age-group Male : 169.1 ±4.9㎝ and 68.0 ±8.5㎏ Female : 157.3 ±4.7㎝ and 56.8 ±7.7㎏ 50-59 age-group Male : 168.1 ±6.8㎝ and 66.0 ±8.1㎏ Female : 157.2 ±4.7㎝ and 57.3 ±7.1㎏ 60-69 age-group Male : 168.0 ±5.3㎝ and 46.7 ±8.7㎏ Female : 155.2 ±5.0㎝ and 56.2 ±9.1㎏ Over 70 age-group Male : 166.1± 6.5㎝ and 62.8±1.2㎏ Female : 152.8 ±5.3㎝ and 52.8 ±8.5㎏ ⅱ) Correlation Coefficient and Linear Regression Equation by Age-groups 30-39 age-group Male : r=+0.44(p<0.001), Y=0.73X-57.94 Female : r=+0.45(p<0.001), Y=0.68X-55.52 40-39 age-group Male : r=+0.54(p<0.001), Y=0.93X-89.92 Female : r=+0.41(p<0.001), Y=0.67X-50.52 50-59 age-group Male : r=+0.32(p<0.001), Y=0.38X-1.22 Female : r=+0.37(p<0.001), Y=0.55X-29.76 60-69 age-group Male : r=+0.51(p<0.001), Y=0.83X-74.84 Female : r=+0.39(p<0.001), Y=0.70X-53.06 over 70 age-group Male : r=+0.63(p<0.001), Y=1.10X-119.96 Female : r=+0.40(p<0.001), Y=0.63X-44.64 Standard Body Weight and Normal Adapted Body Weight of Korean Adult by Age. Using respective regression equation, standard body weight<Table 10, 11>, normal adapted body weight <Table 12~21>, overweight and underweight of the Korean Adult was established for each age group. 6. Obesity Rate of Korean Adult Obesity rate of Korean adult was 9.4% (Male: 9.9%, Female : 8.4%). 7. The Chronological Change on Mean Values of Body Height and Body Weight in Korean Adult The Comparison with the mean values of body height and weight from 1910s to the present 1994 was been remarkably improved, and listed in <Table 23>.

Reactivities of organic isothiocyanates and thiocyanates toward dialkyl bis(phosphine) complexes of palladium(II) and platinum(II)

Lee, S.G.,Choi, K.Y.,Kim, Y.J.,Park, S.,Lee, S.W. Pergamon Press 2015 Polyhedron Vol.85 No.-

Room-temperature reactions of trans-[PdEt<SUB>2</SUB>L<SUB>2</SUB>] (L=PMe<SUB>3</SUB>, PEt<SUB>3</SUB>, PMe<SUB>2</SUB>Ph) with organic isothiocyanates [R-NCS; R=benzyl; CH(CH<SUB>3</SUB>)Ph, R-(-) and S-(+); indanyl, S-(+)] afforded the S,S-coordinated Pd(II) complexes [Pd(S<SUB>2</SUB>C?N-R)L<SUB>2</SUB>] containing a dithiocarbonimidato (S<SUB>2</SUB>C?N-R) group. Similar reactions involving allyl isothiocyanates produced the cationic η<SUP>3</SUP>-allyl Pd complex [Pd(η<SUP>3</SUP>-allyl)(PMe<SUB>3</SUB>)<SUB>2</SUB>]<SUP>+</SUP>(NCS)<SUP>-</SUP>. When [Pd(S<SUB>2</SUB>C?N-R)(PMe<SUB>3</SUB>)<SUB>2</SUB>] was treated with 1equiv of a chelating phosphine [L-L=depe (1,2-bis(diethylphosphino)ethane) and dmpe (1,2-bis(dimethylphosphino)ethane)], the corresponding complexes [Pd(S<SUB>2</SUB>C?N-R)(L-L)] were produced. Reactions of trans-[PdEt<SUB>2</SUB>L<SUB>2</SUB>] (L=PMe<SUB>3</SUB>, PMe<SUB>2</SUB>Ph) with organic thiocyanates (R-SCN; R=benzyl, Et) resulted in the formation of [Pd(CN)<SUB>2</SUB>L<SUB>2</SUB>] and an organic disulfide by S-C bond cleavage of R-SCN. However, similar reactions of the dimethyl analogs, trans-[PdMe<SUB>2</SUB>L<SUB>2</SUB>] (L=PMe<SUB>3</SUB>, PEt<SUB>3</SUB>), with benzyl thiocyanate afforded different products, [Pd(NCS)<SUB>2</SUB>L<SUB>2</SUB>] or [PdMe(NCS)L<SUB>2</SUB>]. Treating [Pt(styrene)(PMe<SUB>3</SUB>)<SUB>2</SUB>] with benzyl isothiocyanate gave the S-coordinated dithiocarbonimidato Pt(II) complex, [Pt(S<SUB>2</SUB>C?N-R)(Me<SUB>3</SUB>P)<SUB>2</SUB>] (R=benzyl). In contrast, cis-[PtEt<SUB>2</SUB>(PMe<SUB>3</SUB>)<SUB>2</SUB>] reacted with the isothiocyanate to afford the trialkyl Pt(IV) complex [PtEt<SUB>2</SUB>(SCN)(CH<SUB>2</SUB>Ph)(PMe<SUB>3</SUB>)<SUB>2</SUB>].
