| 1 | Monochromatic green light stimulation during incubation shortened the hatching time via pineal function in White Leghorn eggs显示文摘Background:Effect of monochromatic green light illumination on embryo development has been reported in chickens.The avian pineal gland is an important photo-endocrine organ formed by a mediodorsal protrusion during embryonic development.However,the involvement of pineal gland in the light transduction process remains to be elucidated.In the present study,we investigated the influence of monochromatic green light on hatching time and explored the possible mechanism via pineal function.Results:A total of 600 eggs of White Leghorn(Shaver strain)were incubated under photoperiods of either 12 h of light and 12 h of darkness using monochromatic green light(12L:12D group)or 24 h of darkness(0L:24D group)for 18 d.Compared to 0L:24D group,the green light stimulation shortened the hatching time without extending the hatch window or impairing hatchability.The liver of embryos incubated in the 12L:12D light condition was heavier than those of the 0L:24D group on d 21 post incubation which may be linked to the observed increase in the serum concentration of insulin-like growth factor 1(IGF-1);primary secretion of the liver.Histological structure analysis of pineal gland demonstrated that the light stimulation increased follicle area,wall thickness and lumen area on d 10 and d 12 post incubation.Rhythmic function analysis demonstrated that three clock related genes(brain and muscle ARNT-like-1,BMAL1;circadian locomotor output cycles kaput,CLOCK;and cryptochrome-1,CRY1)and a melatonin rate-limiting enzyme related gene(arylalkylamine N-acetyltransferase,AANAT)were rhythmically expressed in the pineal gland of the 12L:12D group,but not in the 0L:24D group.Simultaneously,the light stimulation also increased the concentration of melatonin(MT),which was linked to hepatocyte proliferation and IGF-1 secretion in previous studies.Conclusions:The 12L:12D monochromatic green light stimulation during incubation shortened hatching time without impairing hatching performance.Pineal gland’s early histological development and maturation of its rhythmic function were accelerated by the light stimulation.It may be the key organ in the photo-endocrine axis that regulates embryo development,and the potential mechanism could be through enhanced secretion of MT in the 12L:12D group which promotes the secretion of IGF-1. | Panlin Wang Yanyan Sun Yunlei Li Jing Fan Yunhe Zong Adamu Mani Isa Lei Shi Yuanmei Wang Aixin Ni Pingzhuang Ge Linlin Jiang Shixiong Bian Hui Ma Zhengdong Yuan Xiaolin Liu Jilan Chen | 2021 | Journal of Animal Science and Biotechnology2021，12，3： | 3 |

| 6 | Mechanisms of low-frequency sea level fluctuations in the Hangzhou Bay显示文摘-low-frequency sea level fluctuations in the Hangzhou Bay in winter and summer, 1973-1974 are analyzed in this paper. The established multi-spectrum response models effectively identify the different dynamical factors and their contributions to the low-frequency sea level fluctuations inside the bay. The results show that the Ekman transport due to longshore winds is the major mechanism to induce the sea level fluctuations, more important than the frictional effect of local winds. There also exists obviously the influental effect of the free fluctuations of the continental shelf. In addition ,a simple estimation suggests that the remarkable sea level fluctuation of 0. 4 d-1 in the bay is related to the resonance of the Huanghai Sea and the Bohai Sea (taken as a single bay). | Chen Wei and Su Jilan(Received Jme 1, 19891 accepted November 2, 1989) | 1991 | Acta Oceanologica Sinica1991，10，2： | 1 |

| 12 | Poultry genetic heritage cryopreservation and reconstruction:advancement and future challenges显示文摘Poultry genetics resources,including commercial selected lines,indigenous breeds,and experimental lines,are now being irreversibly lost at an alarming rate due to multiple reasons,which further threats the future livelihood and academic purpose.Collections of germplasm may reduce the risk of catastrophic loss of genetic diversity by guaranteeing that a pool of genetic variability is available to ensure the reintroduction and replenishment of the genetic stocks.The setting up of biobanks for poultry is challenging because the high sensitiveness of spermatozoa to freezing–thawing process,inability to cryopreserve the egg or embryo,coupled with the females being heterogametic sex.The progress in cryobiology and biotechnologies have made possible the extension of the range of germplasm for poultry species available in cryobanks,including semen,primordial germ cells,somatic cells and gonads.In this review,we introduce the state-of-the-art technologies for avian genetic resource conservation and breed reconstruction,and discuss the potential challenges for future study and further extending of these technologies to ongoing and future conservation efforts. | Yanyan Sun Yunlei Li Yunhe Zong Gamal M.K.Mehaisen Jilan Chen | 2023 | Journal of Animal Science and Biotechnology2023，14，1： | 0 |
| 13 | An analytical study on the second-order resonance system of tide in an ideal partially-enclosed bay显示文摘In the numerical studies of a real tide M4 resonance system, the Xiangshan Port which is a partially-closed bay, Dong et al. [1999. Acta Oceanologica Sinica, 21 (3): 1~6 ] found the interesting phenomenon that the advection plays an important role in inhibiting the growth of the amplitude of the tidal second-order resonance response (M4). This result is contrary to the general traditional ideas for a non-resonance system. How this phenomenon is interpreted and what internal mechanism is behind the phenomenon are the main focuses of this study. The followings are examined: (1) the dynamic features of a second-order resonance system of tide; (2) the dominating factors on the second-order resonance responses; (3) the effects of both the friction and the advection on the second-order resonance responses; and (4) their roles in dominating the second-order resonance response and internal mechanisms by using the analytical methods. The respective results show that: (1) Both the bottom friction and the advection play significant roles in dominating the magnitude of the amplitude of the second-order resonance responses; (2) the effect of the friction on the second-order resonance response depends on the distribution ratio of the work-done of the system to friction force exhausted into between the damping of the first-order system and the inner excitation of the second-order system; (3) the advection plays a positive role in increasing the amplitude of the second-order non-resonance response in the second order non-resonance of tide; (4) in a second-order resonance system of tide, the effect of the advection may be either to increase or to decrease the amplitudes of the second-order resonance responses of tide,which depends on the distribution ratio mentioned above. | WONG Lai Ah DONG Lixian CHEN Jay Chung SU Jilan | 2005 | Acta Oceanologica Sinica2005，24，5： | 0 |
