Background: Progastrin-releasing peptide (proGRP) is a recently identified biomarker of small cell lung cancer (SCLC). We aimed this study for evaluating the usefulness of automated proGRP measurement for diagnosis and treatment monitoring in patients with SCLC. Methods: From January 2011 to December 2013, plasma samples were prospectively collected from 452 [213 non-small cell lung cancer (NSCLC), 104 SCLC, 135 other diseases] patients visited for tissue diagnosis and tested by two-step automated immunoassay using the ARCHITECT proGRP assay kit (Abbott Diagnostics, USA). The cutoff level of proGRP was set at 63 pg/mL. Results: The mean proGRP was higher in SCLC (1823.0 ± 2684.0 pg/mL) than in NSCLC (61.0 ± 341.7 pg/mL) and other diseases (51.5 ± 222.6 pg/mL, p<0.001). The sensitivity of proGRP was 85.7% (90/105) in SCLC and 11.8% (25/212) in NSCLC. The specificity was 90.2%, positive predictive value was 72.5%, and negative predictive value was 95.4% in SCLC. The mean proGRP was higher in extensive disease (2158.1 ± 2980.6 pg/mL) than in limited disease (901.4 ± 1216.0 pg/mL, p=0.033). Among the 39 patients with SCLC could be followed, the mean proGRP levels of 23 responders were significantly decreased after chemotherapy (from 1651.5 ± 1386.4 pg/mL to 290.0 ± 524.8 pg/mL, p<0.001), whereas those of the 16 non-responders were not. (from 572.5 ± 790.3 pg/mL to 494.4 ± 610.9 pg/mL, p=0.583). Conclusion: Plasma proGRP could be a useful biomarker of SCLC for diagnosis and treatment monitoring. And the initial level may represent the tumor extent of SCLC.

Population-attributable risk of low birthweight related to PM<SUB>10</SUB> pollution in seven Korean cities. <I>Paediatric and Perinatal Epidemiology</I> 2010; <B>24:</B> 140–148.</P><P>To understand the preventable fraction of low birthweight (LBW) deliveries due to maternal exposure to air pollution during pregnancy in Korea, it is important to quantify the population-attributable risk (PAR). Thus, we investigated the association between maternal exposure to air pollution during pregnancy and LBW, and calculated the PAR for air pollution and LBW in seven Korean cities. We used birth records from the Korean National Birth Register for 2004. A geographic information system and kriging methods were used to construct exposure models. Associations between air pollution and LBW were evaluated using univariable and multivariable logistic regression, and the PAR for LBW due to air pollution was calculated.</P><P>Of 177 660 full-term singleton births, 1.4% were LBW. When only spatial variation of air pollution was considered in each city, the adjusted odds ratios unit of particulate matter <10 µm in diameter (PM<SUB>10</SUB>) for LBW were 1.08 [95% confidence interval [CI] 0.99, 1.18] in Seoul, 1.24 [95% CI 1.02, 1.52] in Pusan, 1.19 [95% CI 1.04, 1.37] in Daegu, 1.12 [95% CI 0.98, 1.28] in Incheon, 1.22 [95% CI 0.98, 1.52] in Kwangju, 1.05 [95% CI 1.00, 1.11] in Daejeon and 1.19 [95% CI 1.03, 1.38] in Ulsan.</P><P>The PARs for LBW attributable to maternal PM<SUB>10</SUB> exposure during pregnancy were 7%, 19%, 16%, 11%, 18%, 5% and 16% respectively. Because a large proportion of pregnant women in Korea are exposed to PM<SUB>10</SUB>– which is associated with LBW – a substantial proportion of LBW could be prevented in Korea if air pollution was reduced.</P>

Purpose: The objective of this study is to evaluate the effect of cultivation conditions on the growth and glucosinolate content of Chinese cabbage and kale. Methods: Chinese cabbage and kale were grown in three different cultivation conditions, including a plant factory, greenhouse, and open field. Samples were collected at two harvesting times (10 d and 20 d after transplanting the seedlings). Nine growth parameters (plant height, plant width, number of leaves, petiole diameter, SPAD readout, leaf length, leaf width, stem diameter, and plant weight) were measured immediately after harvesting, and the samples were freeze-dried and stored until the glucosinolate content was analyzed. Mean values of the growth parameters and glucosinolate contents were evaluated using Duncan's multiple range tests. Results: The results indicated that the plant parameters of the Chinese cabbage and kale were greater for plants grown in the plant factory and greenhouse. The plant height, width, and weight showed significant differences in the Duncan's multiple range tests at a 5% level. The plant factory also produced greater contents of most of the glucosinolates. Conclusions: Three different cultivation conditions significantly affected the growth and glucosinolate contents of Chinese cabbage and kale. Further study is necessary to investigate other functional components and different vegetable varieties.

In this study, we developed 15 novel polymorphic simple sequence repeat (SSR) markers by SSR-enriched genomic library construction from Codonopsis lanceolata. We obtained a total of 226 non-redundant contig sequences from the assembly process and designed primer sets. These markers were applied to 53 accessions representing the cultivated C. lanceolata in South Korea. Fifteen markers were sufficiently polymorphic, and were used to analyze the genetic relationships between the cultivated C. lanceolata. One hundred three alleles of the 15 SSR markers ranged from 3 to 19 alleles at each locus, with an average of 6.87. By cluster analysis, we detected clear genetic differences in most of the accessions, with genetic distance varying from 0.73 to 0.93. Phylogenic analysis indicated that the accessions that were collected from the same area were distributed evenly in the phylogenetic tree. These results indicate that there is no correlative genetic relationship between geographic areas. These markers will be useful in differentiating C. lanceolata genetic resources and in selecting suitable lines for a systemic breeding program.

<P><B>Abstract</B></P> <P>Nucleoprotein is highly conserved among each type of influenza viruses (A and B) and has received significant attention as a good target for universal influenza vaccine. In this study, we determined whether a recombinant adenovirus encoding nucleoprotein of type B influenza virus (rAd/B-NP) confers protection against influenza virus infection in mice. We also identified a cytotoxic T lymphocyte epitope in the nucleoprotein to determine B-NP-specific CD8 T-cell responses. We found that B-NP-specific CD8 T cells induced by rAd/B-NP immunization played a major role in protection following influenza B virus infection using CD8 knockout mice. To assess the effects of the administration routes on protective immunity, we immunized mice with rAd/B-NP via intranasal or intramuscular routes. Both groups showed strong NP-specific humoral and CD8 T-cell responses, but only intranasal immunization provided complete protection against both lineages of influenza B virus challenge. Intranasal but not intramuscular administration established resident memory CD8 T cells in the airway and lung parenchyma, which were required for efficient protection. Furthermore, rAd/B-NP in combination with rAd/A-NP protected mice against lethal infection with both influenza A and B viruses. These findings demonstrate that rAd/B-NP could be further developed as a universal vaccine against influenza.</P> <P><B>Highlights</B></P> <P> <UL> <LI> We develop a novel and universal influenza B vaccine based on recombinant adenovirus expressing nucleoprotein (NP). </LI> <LI> Vaccination is capable of inducing B-NP-specific humoral and cellular immune responses. </LI> <LI> This protection correlates with the establishment of resident memory CD8 T cells in the lungs. </LI> <LI> rAd/B-NP immunization combined with rAd/A-NP provides protection against both influenza A and B strains. </LI> </UL> </P>
