Discriminating between eel species of the genus Anguilla using morphological characteristics can be problematic, particularly in the glass eel and elver stages. In this study, sequence-characterized amplified region (SCAR) and polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) markers were developed for the identification of Anguilla japoniea, Anguilla btcoior bicaor. Anguilla rostrata, and Anguilla anguilla. Random amplified polymorphic DNA (RAPD) fragments from A. japoniea (362 bp), A. bicolor bicctor (375 bp), A. rostrata (375 bp), and A. anguilla (375 bp) were isolated, sequenced, and converted to SCAR markers. The principal difference between the SCARs of A. japoniea and the three other species is the absence of a 13 bp deletion in the A. japoniea SCAR. Specific PCR primers amplified a 290 bp fragment for A. japoniea and 303 bp fragments for A. bicolor bicoior. A. rostrata, and A. anguilla. Restriction enzyme digestion with Taql, Mael, and Tru9l yielded PCR-RFLP patterns with differences that, when analyzed together, are sufficient for distinguishing each of the four eel species. In addition, RAPD fragments for A. japoniea (577 bp), A. bicoior bicoor (540 bp), A. rostrata (540 bp), and A. anguilla (509 bp) were also isolated and sequenced. The A. japoniea, A. bicoior blcoior. A. rostrata, and A. anguilla PCR products contain ten, nine, nine, and eight tandem repeats, respectively, of a 37 bp sequence. These results suggest that SCAR and PCR-RFLP markers and repeat numbers for specific loci will be useful for the identification of these four Anguilla eel species.

The objective of present study was to ascertain genetic diversity for cattle parentage testing. A total of 59 random cattle samples(29 Korean native cattle and 30 dairy cows) were genotyped by using 11 microsatellite loci(BM1824, BM2113, ETH10, ETH225, EH3, INRA23, SPS115, TGLA122, TGLA227, TGLA53, and TGLA126). This method consisted of multiplexing PCR procedure and showed reasonable amplification of all PCR products. Genotyping was performed with an ABI 310 genetic analyzer. The number of alleles per locus varied from 5 to 11 with a mean value of 6.73 in the Korean native cattle(KNC), 4 to 9 with a mean of 5.91 in dairy cows(DC). Expected heterozygosity was ranged 0.534~0.855(mean 0.732), 0.370~0.866(mean 0.692) in the KNC and DC, respectively. PIC value was ranged 0.485~0.821(mean 0.684), 0.336~0.834(mean 0.640) in the KNC and DC, respectively. Of the 11 markers, 7 markers(ETH10, EH3, INRA23, SPS115, TGLA122, TGLA227, TGLA53) and 3 markers(INRA23, TGLA227, TGLA53) have relatively high PIC value (>0.7) in the KNC and DC, respectively. The total exclusion probability of 11 microsatellite loci was 0.9997 and 0.9991 in the KNC and DC, respectively. These results present basic information for developing a system for parentage verification and individual identification in the KNC and DC.

To identify the variation of the RAPD patterns between two Atractylodes species, 52 kinds of random primers were applied to each eight of A japonica and A. macrocephala genomic DNA. Ten primers of 52 primers could be used to discriminate between the species and 18 polymorphisms among 67 scored DNA fragments (18 fragments are specific for A. japonica and A. macrocephala) were generated using these primers, 26.9% of which were polymorphic. RAPD data from the 10 primers was used for cluster analysis. The cluster analysis of RAPD markers showed that the two groups are genetically distinct. On the other hand, to identify the variation of the AFLP patterns and select the species specific AFLP markers, eight combinations of EcoRI/MseI primers were applied to the bulked A. japonica and A. macrocephala genomic DNA. Consequently, three combinations of EcoRI/MseI primers (EcoRI /Mse I ; AAC/CTA, AAC/CAA, AAG/CTA) used in this study revealed 176 reliable AFLP markers, 42.0% of which were polymorphic. 74 polymorphisms out of 176 scored DNA fragments were enough to clearly discriminate between two Atractylodes species.

The development of molecular markers is one of the most useful methods for molecular breeding and marker-based molecular associated selections. Even though there is less information on the reference genome, molecular markers are indispensable tools for determination of genetic variation and identification of species with high levels of accuracy and reproducibility. The demand for molecular approaches for marker-based breeding and genetic discriminations in Panax species has greatly increased in recent times and has been successfully applied for various purposes. However, owing to the existence of diverse molecular techniques and differences in their principles and applications, there should be careful consideration while selecting appropriate marker types. In this review, we outline the recent status of different molecular marker applications in ginseng research and industrial fields. In addition, we discuss the basic principles, requirements, and advantages and disadvantages of the most widely used molecular markers, including restriction fragment length polymorphism, random amplified polymorphic DNA, sequence tag sites, simple sequence repeats, and single nucleotide polymorphisms.

PURPOSE: This study examined the effects of cardiopulmonary physiotherapy on the cardiopulmonary function, metabolism, inflammatory markers, and quality of life in patients with coronary artery disease who underwent percutaneous coronary intervention (PCI). METHODS: Electronic bibliographic databases of a regional information sharing system (RISS) and PubMed were searched to identify studies with randomized and non-randomized controlled trials. As the final outcome, 320 publications were identified and 18 studies met the inclusion and exclusion criteria. All studies were assessed for the quality of study using Cochrane's risk of bias. RESULTS: Sixteen studies met the inclusion criteria, in which meta-analysis had been conducted to examine the effectiveness of cardiopulmonary physiotherapy on the cardiopulmonary function, metabolism, inflammatory markers, and quality of life in patients undergoing PCI. Meta-analysis based on a random effect model showed that the cardiopulmonary physiotherapy was beneficial in improving the cardiopulmonary function, metabolism, inflammatory markers, and quality of life. In particular, there was a significant effect on the peak oxygen uptake (effect size 5.30%; 95% confidence interval 3.62~6.97). Cardiopulmonary physiotherapy for a during period of 6 weeks or more was effective in significantly improving the cardiopulmonary function and metabolism function in a subgroup analysis, but cardiopulmonary physiotherapy for less than 6 weeks was not effective. CONCLUSION: Cardiopulmonary physiotherapy has positive effects on the cardiopulmonary function, metabolism, inflammatory markers, and quality of life in patients undergoing PCI.

The purpose of this study was to detect QTL for carcass quality on bovine chromosome (BTA) 6 using a high density SNP map in a Hanwoo population. The data set comprised 45 sires and their 427 Hanwoo steers that were born between spring of 2005 and fall of 2007. The steers that were used for progeny testing in the Hanwoo Improvement Center in Seosan, Korea, were genotyped with the 2,535SNPs on BTA6 that were embedded in the Illumina bovine SNP 50K chip. Four different linkage disequilibrium (LD) mapping models were applied to detect significant SNPs for carcass quality traits; the fixed model with a single marker, the random model with a single marker, the random model with haplotype effects using two adjacent markers, and the random model at hidden state. A total of twelve QTL were detected, for which four, one, three and four SNPs were detected on BTA6 under the respective models (p<0.001). Among the detected QTL, four, two, five and one QTL were associated with carcass weight, backfat thickness, longissimus dorsi muscle area, and marbling score, respectively (p<0.001). Our results suggest that the use of multiple LD mapping approaches may be beneficial in increasing power to detect QTL given a limited sample size and magnitude of QTL effect.
