This study explored the effect of perceived social isolation on the mental health of college students during the high-risk period of COVID-19 transmission in Hubei,China and the role of social support from online friends in alleviating this effect.The questionnaire responses of 213 college students from four universities in Hubei were included.Measurement and structural models were constructed using structural equation modeling.The findings revealed that perceived social isolation while under home quarantine was a negative predictor of the mental health of college students in Hubei.Low social support from online friends may lead to a relatively strong relationship between perceived social isolation and mental health in these college students,whereas high social support from online friends may lead to a relatively weak relationship between perceived social isolation and mental health. 展开更多

[Objective] The study aimed at cloning and analyzing the insulin-like growth factor-1 (IGF-1) gene from liver of Hubei white swine. [Method] The total RNA was extracted by using Trizol from the liver of Hubei white swine and used as template to amplify IGF-1 gene cDNA by RT-PCR. The cDNA product was cloned into pCRII vector, screened with blue-white colonies, digested with double enzymes and sequenced. [Result] The sequencing result indicated that the IGF-1 gene consisted of 607 nucleotides, containing 5'-untranslated region at nucleotides 1-145, a complete ORF at nucleotides 146-538 encoding 130 amino acids, and 3'-untranslated region at nucleotides 539-607. It shared 100% homology with the porcine IGF-1 gene reported by Muller et al. [Conclusion] The successful cloning and sequencing of the Hubei white swine IGF-1 gene confirmed that IGF-I gene was highly conserved, which provided technical basis for the use of transgenic technology for breeding of Hubei white swine. 展开更多

The research explored variation coefficient of grains and analyzed the fluctuations of grains in Hubei in the 1990s in order to investigate quantitative cor- relation between grain production and water-related disaster. The conclusion is that the effective irrigated area and growing structure are major factors influencing grain production capacity, whose grey relational degrees were 0.91 and 0.85 with grain production, respectively. These indicated that water-related disasters have significant effects on grain yield in Hubei Province. 展开更多

Apart from previously reported Small Shelly Fossils (SSFs), a macroscopic fossil assemblage, comprising abundant algae, cone-shaped tubular fossil forms, and probable impressions of a megascopic metazoan, comes from the Lower Cambrian Yanjiahe Formation in the Yangtze Gorges area of western Hubei Province, south China. The visible fossils are preserved in thinlaminated siltstone or muddy siltstone intercalated between 8-15 ram-thick carbonate deposits, probably representing sedimentary settings of a constrained local depression in the shallow water carbonate platform during the Early Cambrian Meishucunian Stage. The macroscopic fossil association provides significant fossil evidence about the evolution of life from the late Precambrian to the 'Cambrian explosion' interval. 展开更多

This paper uses the ecological footprint model to make comparison of the eco-efficiency of arable land ecological footprint in different years in Hubei Province, and makes comparison of that in Hubei and some countries. The results indicate that, since 1965, the eco-efficiency of arable land ecological footprint in Hubei has been improved year by year. However, the efficiency of arable land ecological footprint, compared with some other areas in the world, is much lower. In 1965, average eco-efficiency of world arable land ecological footprint is 3 421 US dollar/hm^2 while that of Hubei Province is 134 US dollar/hm^2, about 1/26 of the world's average level. The eco-efficiency of arable land ecological footprint for 2003 in Hubei Province, however, has become about 1/9 of the world's average level for the same year. Finally the author puts forward the ways to raise the eco-efficiency of arable land ecological footprint. 展开更多

Yanjiahella gen. nov., a distinctive fossil taxon from the Early Cambrian Yanjiahe Biota in Yichang, Hubei Province, is characterized by: 1) an overall body plan composed of a stalk and a calyx (also arms in some species); 2) a stalk with closely spaced, transverse wrinkles and a medial, longitudinal ridge; and 3) a calyx preserved with three-dimensional radiating striations, as well as a probable madreporite in some specimens. Three species that can be assigned to this genus, which are Y. ancarpa sp. nov., Y. monocarpa sp. nov., and Y. biscarpa sp. nov. Yanjiahella is comparable to certain echinoderm taxa in terms of morphology and some biological structures, which might indicate the early evolution and diversification of ancestral echinoderm lineages from the early Early Cambrian Yangtze Platform. The discovery of putative echinoderms in the Yanjiahe Biota provides significant clues about the origination and evolution of the deuterostome phylum Echinodermata. 展开更多
