Epigallocatechin gallate (EGCG), which accounts for approximately 50%-60% of catechins, is the most abundant active component in tea polyphenols. EGCG exhibits a variety of biological functions and has significant potential for development. This article summarizes the functions and mechanisms of EGCG in antioxidant, antibacterial, anti-inflammatory, and antiviral activities. In addition, it discusses the application of EGCG in animal production, aiming to provide a theoretical basis for the precise application of EGCG in livestock and poultry feed.

In order to explore the difference and taxonomic significance through the characteristics of the lenticel, stomatal apparatus and lower epidermis of leaf of different kiwifruit species, the optical microscope was used to observe kiwifruit lenticels on one-year-old phloem of nine samples from five different species. Kiwifruit lenticels showed long elliptical or spindle shape. The values of length × width, lenticle density, lenticle area and percentage of lenticle area of different species were different and no obvious rule with species division. However, the four Actinidia chinensis varieties from selected samples could be clearly distinguished by the width of the lenticels. The results of scanning electron microscope showed that the stomatal apparatus only existed in blade back and mesophyll area with wide oval and elliptical shape, and the stomatal apparatus types were actinotytic, cyclocytic, anisocytic and anomocytic. Among these species, the stomatal apparatus shape of A. chinensis was actinotytic, the stomatal apparatus shape of A. deliciosa was cyclocytic, the stomatal apparatuses shapes of A. latifolia and A. eriantha were anisocytic, and the stomatal apparatus shape of A. longicarpa was anomocytic. Guard cells were arranged around stomatal apparatus, horizontal or protruding from the lower epidermis. The lower epidermal cells were papillose or anomocytic with sinuate or sinuolate anticlinal wall. The lower epidermis was granulated with furcal pubescence and bifurcate single cell without glandular trichome. Some germplasm had papillose or flake-like waxy layer. Inner margin of outer stomatal rim were sinuolate with ornamentation. According to the measure of length × width, axis and density of stomatal apparatus, there was no obvious rule with kiwifruit species division. However, the stomatal apparatus type and the species division were consistent well. Four A. chinensis varieties could be distinguished by the length, axis of stomatal and density of stomatal apparatus. In addition, there were significant differences in the microapparent morphology between A. longicarpa and other species, which provides microcosmic basis for its identification [ABSTRACT FROM AUTHOR]

In order to provide theoretical base for kiwifruit mutation breeding and speed up the breeding process，the variability among irradiation-treated kiwifruit ‘Changguo’ samples were analyzed. The branches of kiwifruit ‘Changguo’ from 55 samples were irradiated by 60Co-y ray in 0 (CK)，40，60，80 and 100 Gy，respectively. The polymorphism of these 5 treatments were analyzed using ISSR molecular marker technology. The results showed that 7 screened primers were used for marking from 100 oligonucleotide primers. The average amplified fragment was 14.3，and the polymorphic bands number was 6.7. The polymorphic ratio was 46. 85 % . Calculated genetic similarity coefficient was from 0 .9 to 1. 00. Clustering analysis suggested that the V class was 6-8 plants of 60Gy，which the genetic distance was the farthest， and the variation was the largest compared with others. Large genetic variation in kiwifruit was induced by irradiation. It is accurate to measure whether irradiation samples are mutants using ISSR for mutant cultivar. [ABSTRACT FROM AUTHOR]

Medium workers of Solenopsis invicta was treated with 0. 5% hexaflumuron bait, and their climbing ability, attack ability, walking ability and adhesive ability were studied in field experiments. The resut showed that the climbing pole rate of medium workerr treated with 0. 5 % hexaflumuron bait for 1, 3, 5 and 7 d were 66. 67 % , 30. 00 %，23. 33 % and 20. 00 %，respectively，the attack rates were 76. 67 %，60. 00 %，56. 67 % and 53. 33 %，the reduce rates of walking ability were 6. 00 %，19 %，22. 00 % and 52.00 %， and the adhe sive rates were 100. 00 %，76. 67 %，63. 33 % and 63. 33 %. Hexaflumuron bait possessed control effect against the medium workers of Solenopsis invicta which was treated with Hexaflumuron bait for 3 - 9 days，and their mortality was 30 % - 35 %. The control effect values against Solenopsis invicta with 0.5% hexaflumuron bait at 15g/nest for 3, 7, 14 and 30 days were 39. 58 % , 53. 55 %，60. 77 % and 78. 12 % , respectively. It was concluded that hexaflumuron bait was potential for controlling S. invicta. [ABSTRACT FROM AUTHOR]

Objective To isolate and amplify the Sca-1 positive cardiac stem cells from C57BL/6 mice in vitro and to observe its markers. Methods The myocardial tissues from C57BL/6 mice were selected, and we separated the Sca-1 positive cells by the magnetic cell sorting and amplified its passage. We observed the morphology changes in the culture process. The flow cytometry was used to test the Sca-1+purity of the primary and fifth generation of myocardial cells. RT-PCR was used to detect the expression of multiple factors (MYH6, cTnT and GATA4) in the isolated Sca-1 positive cells and negative cells. Results The primary cultured Sca-1 positive cells were round, smaller than blood cells; the sub-cultured were starlike, and the pseudopodia were long, and after the fifth generation, the morphology of cells showed little difference. The Sca-1+positive rates of primary and the fifth generation were 81%±10.4% and 90%±5%, separately (P>0.05). The relative expression of MYH6, cTnT and GATA4 in Sca-1+cells was 0.5 ±0.21, 0.72 ±0.04 and 0.72 ±0.05, separately;while the expression in the Sca-1 -cells was 0.2 ±0.02, 0.86 ±0.06 and 0.71 ±0.05.Significant difference was found in the expression of MYH6 and cTnT (all P<0.05). Conclusion Sca-1 positive cardiac stem cells can be isolated successfully and sub-cultured stablely. Furthermore, Sca-1+cells show high expression of MYH6. [ABSTRACT FROM AUTHOR]
