Abstract

Social participation comprises comprehensive interactions between individual health and relevant environmental characteristics, which play an increasingly important role in promoting older adults' health and quality of life. Although many studies have examined impacts of various factors on the social participation of older adults, some internal mechanisms between health characteristics and environmental characteristics have not been revealed. This study aimed to examine the moderating effects of health characteristics on the relationships among psychological resources, social network support, community support and social participation of Chinese older adults. Based on some key health indicators, this study used the two‐step cluster algorithm to divide the participants aged over 60 years from the Chinese Longitudinal Aging Social Survey in 2016 (N = 8669) into low (47.2%), moderate (33.8%) and high (18%) health risk groups. A multiple‐group structural equation model was then built to examine the effects of psychological resources, social network support and community support on social participation across the three groups. The results suggested that with the increase in health risks, the contributions of psychological resources and community support to social participation decreased from 28.6% to 23.7% and from 61.5% to 50.7%, respectively, while that of social network support increased from 9.9% to 25.6%. These variations suggest that individual health has a significant moderating effect on the psychological and social compensating mechanisms of the social participation among Chinese older adults.

Abstract

The complete CDS sequence of the bovine FABGL gene was determined by homology cloning approach combined with RT-PCR and 3'- and 5'-RACE. The results of sequence analysis and bioinformatics study showed that this cDNA contained 994 nucleotides, with a 780 bp open reading frame (ORF) flanked by a 16 bp 5'-UTR (incompletely) and a 198 bp 3'-UTR. The deduced amino acid sequence (260 AA) shows 88% identity with the corresponding sequence in humans. Two single nucleotide substitutions, one located in intron 5 (I5) at position 1 065 bp (Y = C/T) (GenBank: DQ409814) and the other in intron 8 (I8) at position 1 792 bp (R = A/G), were detected using the PCR-SSCP method. Analysis of the allele frequencies of the two polymorphic sites in three different cattle breeds (Angus, Hereford, and Simmental) with different genotypes showed large differences: in locus I8, cattle with the GG genotype showed higher beef performance index (BPI) (4.283 +/- 0.475 kg/cm) in comparison with cattle with the AA genotype (4.008 +/- 0.465 kg/cm) (P = 0.01). Regarding the ribeye area, cattle with the GG genotype showed significantly higher ribeye area (73.380 +/- 13.005 cm(2)) compared with cattle with the AA genotype (67.744 +/- 12.777 cm(2)) (p = 0.05). In locus I5, some associations for the average daily gain (ADG) were found at the significance level of 0.01 between three different genotypes (CC, CT, TT): cattle with the TT genotype showed the highest ADG (0.652 +/- 0.330 kg/d), whereas cattle with the CC genotype showed the lowest ADG value (0.421 +/- 0.178 kg/d).

22. Molecular characterization, polymorphism of growth differentiation factor 5 gene and association with ultrasound measurement traits in native Chinese cattle breeds

Author

Liu, Yongfeng, Jiao, Yang, Zan, Linsen, Xin, Yaping, Li, Linqiang, and Tian, Wanqiang

Abstract

Growth differentiation factor 5 (GDF5), involved in the development and maintenance of bone andcartilage, is a n important candidate gene for growth and carcass traits selection through markerassisted selection (MAS). Genomic structural analysis showed that bovine GDF5 shares much similarity with human GDF5. The latest findings demonstrate that the single nucleotide polymorphism (SNP) T586C in exon 1 is significantly associated with ultrasound marbling score (UMAR) and ultrasound backfat thickness (UBF). Furthermore, the analysis of T586C SNP marker shows there are significant effects on the UBF (P = 0.0498) and on the UMAR (P = 0.0058) in 465 individuals. These results clearly suggest that the GDF5 gene is among target genes for carcass traits in bovine reproduction and breeding.Keywords: Cattle, GDF5 gene, ultrasound measurement, polymorphism, association analysisAfrican Journal of Biotechnology Vol. 9(33), pp. 5269-5273, 16 August, 2010

30. Part 5: Capacity and Quality of Service: Assessing Transit Level of Service Along Travel Corridors: Case Study Using the Transit Capacity and Quality of Service Manual

Author

Xin, Yaping, Fu, Liping, and Saccomanno, Frank

Abstract

This paper describes a case study of applying the recent edition of the Transit Capacity and Quality of Service Manual (TCQSM) to evaluate the quality of transit service on several travel corridors in an urbanized area. The study focuses mainly on four level-of-service (LOS) measures: service frequency, hours of service, service coverage, and transit-auto travel time. Assumptions are introduced to extend these measures, which are intended for a particular element of a transit system—such as stops and route segments—so that they become applicable for measuring the quality of transit service of travel corridors. An extensive case analysis indicates that all LOS measures are sensitive to various transit planning variables and can be easily calculated with readily available data. The research has also identified a range of issues with the current TCQSM methodology.

Abstract

The bovine genetic resources in China are diverse, but their value and potential are yet to be discovered. To determine the genetic diversity and population structure of Chinese cattle, we analyzed the whole genomes of 46 cattle from six phenotypically and geographically representative Chinese cattle breeds, together with 18 Red Angus cattle genomes, 11 Japanese black cattle genomes and taurine and indicine genomes available from previous studies. Our results showed that Chinese cattle originated from hybridization between Bos taurus and Bos indicus. Moreover, we found that the level of genetic variation in Chinese cattle depends upon the degree of indicine content. We also discovered many potential selective sweep regions associated with domestication related to breed-specific characteristics, with selective sweep regions including genes associated with coat color (ERCC2, MC1R, ZBTB17, and MAP2K1), dairy traits (NCAPG, MAPK7, FST, ITFG1, SETMAR, PAG1, CSN3, and RPL37A), and meat production/quality traits (such as BBS2, R3HDM1, IGFBP2, IGFBP5, MYH9, MYH4, and MC5R). These findings substantially expand the catalogue of genetic variants in cattle and reveal new insights into the evolutionary history and domestication traits of Chinese cattle., (© The Author 2017.
