BACKGROUND/OBJECTIVES: Several previous studies have investigated whether regular walnut consumption positively changes heart-health-related parameters. The aim of this study was to investigate the effects of daily walnut intake on metabolic syndrome (MetS) status and other metabolic parameters among subjects with MetS. SUBJECTS/METHODS: This study was a two-arm, randomized, controlled crossover study with 16 weeks of each intervention (45 g of walnuts or iso-caloric white bread) with a 6 week washout period between interventions. Korean adults with MetS (n = 119) were randomly assigned to one of two sequences; 84 subjects completed the trial. At each clinic visit (at 0, 16, 22, and 38 weeks), MetS components, metabolic parameters including lipid profile, hemoglobin A1c (HbA1c), adiponectin, leptin, and apolipoprotein B, as well as anthropometric and bioimpedance data were obtained. RESULTS: Daily walnut consumption for 16 weeks improved MetS status, resulting in 28.6%-52.8% reversion rates for individual MetS components and 51.2% of participants with MetS at baseline reverted to a normal status after the walnut intervention. Significant improvements after walnut intake, compared to control intervention, in high-density lipoprotein cholesterol (HDL-C) (P = 0.028), fasting glucose (P = 0.013), HbA1c (P = 0.021), and adiponectin (P = 0.019) were observed after adjustment for gender, age, body mass index, and sequence using a linear mixed model. CONCLUSION: A dietary supplement of 45 g of walnuts for 16 weeks favorably changed MetS status by increasing the concentration of HDL-C and decreasing fasting glucose level. Furthermore, consuming walnuts on a daily basis changed HbA1c and circulating adiponectin levels among the subjects with MetS. This trial is registered at ClinicalTrials.gov as NCT03267901.

에메리개미는 여왕개미와 수개미가 유전적으로 복제되어 번식한다고 알려져 있으며, 여왕개미의 날개형태가 장시형과 단시형으로 나타난다. 장시형은 정상적인 날개형태이고, 이보다 짧은 날개형태는 단시형이라고 한다. 장시형과 단시형 모두 한 종으로 취급되지만, 두 가지 점에서 종지위에 대한 조사가 필요하다. 첫째, 자연 상태에서는 두 날개형이 함께 발견되지 않고, 둘째, 날개형이 육안으로 뚜렷하게 구분된다. 또한 복제되어 번식한 여왕개미가 단수체인지 배수체인지 조사가 필요하다. 따라서 우리는 본 연구에서 에메리개미 유전체 크기를 추정하여 두 날개형은 동종이며, 여왕개미는 배수체임을 확인하였다.

산업화의 추세에 따라 수요가 급증하고 있는 고전력을 생산하기 위하여 시설장비 및 부하의 대용량화가 수반되고 있다. 전기설비의 규모는 점차 복잡해 지고, 대규모화 됨으로써 고도 정보화 사회로의 발전에 크게 기여하고 있다. 그러나, 발전 설비에서 불의의 사고가 발생하여 전기의 생산이 중단된다면, 전기에 의존하여 작동 중인 수 많은 장비가 지장을 받게되고, 산업사회에 막대한 경제적 손실 및 장애를 초래하게 된다. 사고가 발생한 발전설비를 복구하기 위해서는 많은 시간과 비용이 소요되어 국가 산업 활동에 막대한 경제적 피해를 끼치게 된다. 사고를 미연에 방지하기 위하여 케이블의 동작 상태를 정기적으로 감시 확인하여야 한다. 우리는 사고가 가장 빈번하게 발생하는 접속부에 대해 안정적인 사용을 위한 진단의 정확성과 신뢰성을 향상시키기 위한 연구를 하였다. 이 논문에서 데이터 취득을 하고, 통계적 처리를 하기 위한 방법을 제시한다.

Objective: Recently, there has been an increasing interest in conservation of native genetic resources of chicken on a worldwide basis. Most of the native chicken breeds are threatened by extinction or crossing with ecotypes. Methods: Six Saudi native chicken breeds including black naked neck, brown frizzled, black, black barred, brown and gray were used in the current study. The aim of the current study was to evaluate genetic diversity, relationship and population structure of Saudi native chicken breeds based on 20 microsatellite markers. Results: A total of 172 alleles were detected in Saudi native chicken breeds across all 20 microsatellite loci. The mean number of alleles per breed ranged from 4.35 in gray breed to 5.45 in normally feathered black with an average of 8.6 alleles. All breeds were characterized by a high degree of genetic diversity, with the lowest heterozygosity found in the brown breed (72%) and the greatest in the frizzled and black barred populations (78%). Higher estimate of expected heterozygosity (0.68) was found in both black breeds (normal and naked neck) compared to the other chicken populations. All studied breeds showed no inbreeding within breed (negative inbreeding coefficient [$F_{IS}$]). The phylogenetic relationships of chickens were examined using neighbor-joining trees constructed at the level of breeds and individual samples. The neighbor-joining tree constructed at breed level revealed three main clusters, with naked neck and gray breeds in one cluster, and brown and frizzled in the second cluster leaving black barred in a separate one. Conclusion: It could be concluded that the genetic information derived from the current study can be used as a guide for genetic improvement and conservation in further breeding programs. Our findings indicate that the Saudi native chicken populations have a rich genetic diversity and show a high polymorphism.
