This study performed a comprehensive expression profiling of genes expressed in the skin of goats with three different coat colors by Illumina Sequencing. A total of 91 significantly expressed genes were detected when comparing gray skin to white skin library and these included 74 up-regulated and 17 down-regulated genes in gray skin. There were 67 differentially expressed genes between brown skin and white skin libraries, 23 of which were up-regulated and 44 were down-regulated in brown skin. When we compared brown and gray libraries, 154 differentially expressed genes were found, of which 33 showed higher expression and 121 showed lower expression in brown skin. To our surprise, MC1R, MITF, TYR and KIT showed no significant difference in expression between the goats with three skin colors, whereas ASIP was detected in white skin but not in dark skins. In this study, PMEL, TRPM1, TYRP1 and DCT were significantly upregulated in brown goat skin compare with gray and white skins. PMEL showed higher expression in gray goat skin compared with white goat skin, whereas there were no significant differences in the expression of TYRP1, TRPM1 and DCT between gray and white skin samples. In addition, ELOVL3 showed higher expression in gray goat skin than in brown and white skins, whereas there was no significant differences in the expression of ELOVL3 between brown and white skin samples. These results expand our understanding of the complex molecular mechanisms of skin physiology and melanogenesis in goat and provide a foundation for future studies.

Background/Aims: Older adults are vulnerable to central obesity, while the association of changes in central fatness with risk of diabetes and metabolic control has not been investigated among this particular population. This study was aimed to address these issues. Methods: A total of 1,815 adults aged ≥ 60 years without diabetes at baseline were followed for 4 years. Incident diabetes was ascertained based on plasma glucose, hemoglobin A1c, medical history, and/or the use of anti-diabetic drugs. Central fatness was assessed by waist circumference (WC), waist-height ratio (WHtR), and body roundness index (BRI). Logistic re gression analyses were used to assess the association of changes in central fatness with risk of diabetes, along with dose-re sponse and mediation analyses. Results: During the 4-year follow-up, 177 participants developed diabetes. The risk of diabetes was increased by 42%, 41%, and 40% per 1 standard deviation increases in WC, WHtR, and BRI, respectively, in multivariable-adjusted models (all p < 0.01). Moreover, these relationships were all linearly-shaped (all p<sub>nonlinearity</sub> ≥ 0.11). Increases in WC, WHtR, and BRI correlat ed with increases in hemoglobin A1c, triglycerides-and-glucose index, triglycerides, white blood cell, and C-reactive protein (all p ≤ 0.04). Yet only changes in hemoglobin A1c and triglycerides-and-glucose index were identified as the possible mediators for risk of diabetes, with their mediating effect being about 35% and 21%, respectively. Conclusions: Increases in central fatness were related to elevated risk of diabetes, and this association might be partly ex plained by the worsening of glycemic control and insulin resistance in older adults.

Hongmian Road goes under Jihe highway by the way of tunnel in Shenzhen City, Guangdong Province, China. The tunnel hassome special characteristics such as shallow depth, large span, soft soil, busy traffic, and long distance under-crossing the operatinghighway, thus there is great difficulty and risk during its construction. A series of in-situ tests were conducted to reveal deformationcharacteristics during tunneling beneath the existing highway by the double-side-drift method (DSDM). The results show that initialconstruction method and measures can't meet the safety requirement of tunnel construction, and the level of risk is extremely high, sothe construction method need to be timely adjusted. By comprehensive analysis, the double-side-drift optimum method (DSDOM) isput forward, on the basis of which a series of optimum measures also have been put forward, such as reasonable constructionmethods, the suitable length of bench and excavation, soil reinforcement measures on tunnel face, optimizing construction process,closing primary support in time and speeding up the construction of secondary lining. Then the feasibility of this optimizedconstruction method and measures are verified by the numerical simulations. Finally, from feedbacks of monitoring results, theoptimum method and measures have been proved to be reasonable and feasible, and they can guarantee a successful pass beneath theoperating highway.
