OBJECTIVE: To explore embryonic skeleton development and neonatal learning and memory of rats anesthetized with pentobarbital sodium in gravid rats. DESIGN: A randomized control trial. SETTING: Laboratory Animal Center of Xuzhou Medical College. MATERIALS: A total of 80 adult female SD rats, of clean grade and weighing 220-240 g, were selected in this study. The main reagents were detailed as follows: pentobarbital sodium (Shanghai Xingzhi Chemical Plant, batch number: 921019); MG-2 maze test apparatus (Zhangjiagang Biomedical Instrument Factory); somatotype microscope (Beijing Taike Instrument Co., Ltd.). METHODS: ① A total of 160 SD rats of half males and females were selected in this study. All rats were copulated. The day that the plug was checked out in the vagina next day was looked as the first day of pregnancy. Gravid rats were divided randomly into four groups, including early anesthesia group, second anesthesia group, late anesthesia group and control group with 20 in each group. Rats in the early anesthesia group were injected with 25 mg/kg soluble pentobarbitone on the 7th day of pregnancy for once; rats in the second anesthesia group were anesthetized with 25 mg/kg soluble pentobarbitone on the 7th and the 14th days of pregnancy for once; rats in the late anesthesia group were anesthetized with 25 mg/kg soluble pentobarbitone on the 14th day of pregnancy for once; rats in the control group did not treat with anything. The time of anesthetizing was controlled in 3 to 4 hours and ether was absorbed while the time was not enough. ② Half of each group was sacrificed on day 20th of pregnancy and the fetus was taken out to be stained with alizarin red S. After stained, the fetal skeleton was examined. The learning and memorizing of one-month rats that were given birth by the rest gravid rats were tested through electric mare method. Determine their study ability according to their correct rate of 90% or above of arrival at the safe area in 20 s. After they finally learned to arrive at the safe area correctly, test them once more in 24 hours and record the correct rate of 15 times. MAIN OUTCOME MEASURES: The rate of malformation in fetus and ability of learning and memory in one-month rats. RESULTS: A total of 80 female rats were anesthetized in this experiment. Totally 490 immature rats were tested with maze testing machine and 196 fetuses were stained with alizarin red S to observe the development of their skeleton. However, one of the 80 female rats was led to death because of overdose. ① Malformation experiment: Learning ability of second anesthesia group was evidently different from the control group while the other two groups were not in the electric mare method. The fetal skeleton malformation rate of three experimental groups was 87.0%, 60.9% and 17.9%, respectively, while it was 5.6% in the control group. ② Electric mare method: Times of rats which arrived at the safe regions were respectively 49.0±31.0, 68.0±35.0, 47.0±31.0 and 44.0±21.0 in early anesthesia group, second anesthesia group, late anesthesia group and control group; and then, there was significant difference between the second anesthesia group and the control group (P < 0.05). Exact rates of memory of rats were respectively (64.36±14.35)%, (62.15±18.33)%, (54.19±12.28)% and (68.24±15.91)% in early anesthesia group, second anesthesia group, late anesthesia group and control group; and then, there were no significant differences as compared with the control group (P > 0.05). CONCLUSION: The influence of anesthesia with pentobarbital sodium is obvious in fetal skeleton development and learning and memory ability.展开更多

And the agent and practitioner of all the nature and content of these are teachers in universities and colleges which are the main power of education, teaching and research. Highly qualified team of teachers have an important value for higher education. New mode of higher education has also undergone a significant change from denotative growth gradually to connotative development concerning over personnel training and teaching quality, which bring up more requirements for the quality and ability of university teachers. Thus we will put forward a comprehensive analysis of how to comply with cormotative development and come up with new strategy of teachers' pro fessional development.展开更多

文摘Nitrogen(N)fertilization is critical for spike and floret development,which affects the number of fertile florets per spike(NFFs).However,the physiological regulation of the floret development process by N fertilization is largely unknown.A high temporal-resolution investigation of floret primordia number and morphology,dry matter,and N availability was conducted under three N fertilization levels:0(N0),120(N1)and 240(N2)kg ha^(−1).Interestingly,fertile florets at anthesis stage were determined by those floret primordia with meiotic ability at booting stage:meiotic ability was a threshold that predicted whether a floret primordium became fertile or abortive florets.Because the developmental rate of the 4th floret primordium in the central spikelet was accelerated and then they acquired meiotic ability,the NFFs increased gradually as N application increased,but the increase range decreased under N2.There were no differences in spike N concentration among treatments,but leaf N concentration was increased in the N1 and N2 treatments.Correspondingly,dry matter accumulation and N content of the leaf and spike in the N1 and N2 treatments was increased as compared to N0.Clearly,optimal N fertilization increased leaf N availability and transport of assimilates to spikes,and allowed more floret primordia to acquire meiotic ability and become fertile florets,finally increasing NFFs.There was no difference in leaf N concentration between N1 and N2 treatment,whereas soil N concentration at 0–60 cm soil layers was higher in N2 than in N1 treatment,implying that there was still some N fertilization that remained unused.Therefore,improving the leaf’s ability to further use N fertilizer is vital for greater NFFs.
文摘The research concluded peasants' willingness on homestead exiting and influential factors by questionnaire survey and interviewing in two villages with varied levels of economic development in Anhui Province.Comparisons were performed on subjective factors and objective factors were explored by Logistic regression.The results showed that both of education background and homestead use have positive correlation with peasants' willingness on homestead exit;the number of family members has negative effects on peasants in advanced village but the number of migrant workers or members living in cities has positive effects;the area of homestead has positive effects on peasants in underdeveloped village.Therefore,the emphasis should be varied on homestead exit upon village economy and it is necessary to reinforce homestead exit promotion at improving immigrants' reception work,social security,employment,and education.

文摘BACKGROUND: Generally speaking, anesthesia is often used in gravid body and it has been already proved that many kind of medicine can result in malformation. OBJECTIVE: To explore embryonic skeleton development and neonatal learning and memory of rats anesthetized with pentobarbital sodium in gravid rats. DESIGN: A randomized control trial. SETTING: Laboratory Animal Center of Xuzhou Medical College. MATERIALS: A total of 80 adult female SD rats, of clean grade and weighing 220-240 g, were selected in this study. The main reagents were detailed as follows: pentobarbital sodium (Shanghai Xingzhi Chemical Plant, batch number: 921019); MG-2 maze test apparatus (Zhangjiagang Biomedical Instrument Factory); somatotype microscope (Beijing Taike Instrument Co., Ltd.). METHODS: ① A total of 160 SD rats of half males and females were selected in this study. All rats were copulated. The day that the plug was checked out in the vagina next day was looked as the first day of pregnancy. Gravid rats were divided randomly into four groups, including early anesthesia group, second anesthesia group, late anesthesia group and control group with 20 in each group. Rats in the early anesthesia group were injected with 25 mg/kg soluble pentobarbitone on the 7th day of pregnancy for once; rats in the second anesthesia group were anesthetized with 25 mg/kg soluble pentobarbitone on the 7th and the 14th days of pregnancy for once; rats in the late anesthesia group were anesthetized with 25 mg/kg soluble pentobarbitone on the 14th day of pregnancy for once; rats in the control group did not treat with anything. The time of anesthetizing was controlled in 3 to 4 hours and ether was absorbed while the time was not enough. ② Half of each group was sacrificed on day 20th of pregnancy and the fetus was taken out to be stained with alizarin red S. After stained, the fetal skeleton was examined. The learning and memorizing of one-month rats that were given birth by the rest gravid rats were tested through electric mare method. Determine their study ability according to their correct rate of 90% or above of arrival at the safe area in 20 s. After they finally learned to arrive at the safe area correctly, test them once more in 24 hours and record the correct rate of 15 times. MAIN OUTCOME MEASURES: The rate of malformation in fetus and ability of learning and memory in one-month rats. RESULTS: A total of 80 female rats were anesthetized in this experiment. Totally 490 immature rats were tested with maze testing machine and 196 fetuses were stained with alizarin red S to observe the development of their skeleton. However, one of the 80 female rats was led to death because of overdose. ① Malformation experiment: Learning ability of second anesthesia group was evidently different from the control group while the other two groups were not in the electric mare method. The fetal skeleton malformation rate of three experimental groups was 87.0%, 60.9% and 17.9%, respectively, while it was 5.6% in the control group. ② Electric mare method: Times of rats which arrived at the safe regions were respectively 49.0±31.0, 68.0±35.0, 47.0±31.0 and 44.0±21.0 in early anesthesia group, second anesthesia group, late anesthesia group and control group; and then, there was significant difference between the second anesthesia group and the control group (P < 0.05). Exact rates of memory of rats were respectively (64.36±14.35)%, (62.15±18.33)%, (54.19±12.28)% and (68.24±15.91)% in early anesthesia group, second anesthesia group, late anesthesia group and control group; and then, there were no significant differences as compared with the control group (P > 0.05). CONCLUSION: The influence of anesthesia with pentobarbital sodium is obvious in fetal skeleton development and learning and memory ability.

文摘It is possible to say that the automotive industries of Argentina,Brazil,and Turkey are each developed as an assembly industry and show great similarities to each other in this context.Since the 1980s,the development direction of the world automotive industry has been trying to make the country’s investment environment attractive for foreign international companies to produce in their countries in all three countries.However,with the 1980s,their adaptation to the flexible production system and other new technologies being implemented in the Japanese automotive industry took time,meaning that the learning time took a long time,and local contribution rates fell.This has made the slow development mechanism that has been going on since the past work even slower,and they have suffered the punishment for not being able to develop technologies in all three countries by falling behind in the automotive industry.In the 2000s,with technological advances in electric vehicles,when the use of electric vehicles began to become widespread,we can say that all three countries began to experience a new adaptation problem in the automotive industry more severely.In Turkey,this problem was experienced with all its weight along with the other country;in 2006,the policy of attracting foreign investment to the automotive industry was partially abandoned and the approach to producing domestic cars began to be considered,and in 2011,a decision was made to produce domestic cars.As of December 2019,a prototype of the domestic car has been produced by the automobile initiative group of Turkey and work has started for mass production.Thus,the problem of adaptation to the production of electric vehicles was desired to be overcome by moving to a new stage in the path of technology development.The South Korean automotive industry used this approach in the 1980s and was successful and soon gained the ability to develop technology.In order to see the success of the application of this method in Turkey,it is thought that it is necessary to wait for the result of the domestic car project.

文摘Light is essential for embryonic development in many ovipa rous animals including fish,amphibians,and birds.However,light may be harmful for reptile embryos developing underground where they are in complete darkness and beneath thin eggshells.Nonetheless,how embryonic light conditions affect reptile development and offspring remains largely unknown.Here we incubated eggs in dark and light conditions to determine the effects of light exposure on embryonic development and offspring visual ability,spa tial cognitive ability and growth in a lacertid lizard,Eremias argus.Our experiments demonstrated that light stimulation shortened incubation duration of eggs,but did not affect hatching success,offspring size,visual ability or survival More interestingly,light exposure during incuba tion decreased spa tial cognitive ability and post-hatching growth of offspring On the basis of nega tive effects on offspring growth rates,our study indicates that in squamate reptiles with thin eggshells,light exposure in early development has negative effects on offspring cognitive ability.
文摘With the development of higher education in China, the social responsibility undertaken by higher education is becoming more and more obvious and knowledge innovation in universities, scientific research, teaching and others have played an important role for social and economic development. And the agent and practitioner of all the nature and content of these are teachers in universities and colleges which are the main power of education, teaching and research. Highly qualified team of teachers have an important value for higher education. New mode of higher education has also undergone a significant change from denotative growth gradually to connotative development concerning over personnel training and teaching quality, which bring up more requirements for the quality and ability of university teachers. Thus we will put forward a comprehensive analysis of how to comply with cormotative development and come up with new strategy of teachers' pro fessional development.
文摘It is possible to say that each of the Mexican and Turkish automotive industries is developed as an assembly industry and shows great similarities to each other within this framework.However,due to its geographical proximity,the role of US-based automotive companies in the formation of the Mexican automotive industry has become greater,while the Ford Motor company,which entered the US automotive industry in Turkey,was able to take part only with the initiatives of the Otosan company in the 1960s.Another feature of the 1960s is that there were efforts to manufacture domestic cars in Turkey.Since the 1980s,in line with the direction of development of the world automotive industry,Turkey has been trying to make the country’s investment environment attractive for foreign international companies to produce in their countries.In Mexico,even with the possibility of reaching new markets by providing 1990 regional agreements NAFTA ruling party of the Mexican automotive industry,we can say that U.S.firms were largely determined by the direction of development,Turkey’s automotive industry development direction of the company is determined by the first European,then we can say that companies are becoming more efficient in the Far East countries.On the other hand,the US Ford Motor company considered it sufficient to be involved in the Turkey directly.Turkey has decided to return from the policy of attracting foreign investments to its country since 2006,and in 2011 it was decided to produce domestic cars.As of December 2019,a prototype of a domestic car has been produced by the Automobile Enterprise Group of Turkey and work has begun on mass production.Thus,the problem of adaptation to the production of electric vehicles was decided to be overcome by moving to a new stage on the way to technology development.This approach was used by the South Korean automotive industry in the 1980s and was successful,and the ability to develop technology was acquired in a short time.In order to see the success of the application of this method in Turkey,it is thought that it is necessary to wait for the result of the domestic automobile project.Mexico’s policy of opening up more to foreign investments has been successful since the 1990s,and Mexico has become the most productive country in Latin America,surpassing Brazil in automotive industry production.
