| 2 | Effects of a glyphosate-based herbicide on the oestrous cycle of rats显示文摘Objective:To determine the effects of a glyphosate-based herbicide on the oestrous cycle of rats.Methods:Fifteen adult Wistar rats were randomly divided into three groups.Group A served as the control group,while groups B and C received 250 and 500 mg/kg of glyphosate-based herbicide orally for five oestrous cycles,respectively.Stages of oestrous cycle,oestrous cycle index,length of cycle,oestrous cycle ratio,serum estradiol and progesterone levels were determined.Results:The proestrus and oestrus stages of the glyphosate-based herbicide groups increased significantly(P<0.05),although proestrus in group C was not significantly different from the control group.There was a significant decrease in the metestrus and diestrus of the glyphosate-based herbicide groups(P<0.05).The oestrous cycle index of the glyphosate-based herbicide treated groups was altered;this was characterized by an increase in the oestrous index and a decrease in the metestrus and diestrus indexes.The proestrus index of group B increased,while that of group C decreased.The length of the cycle of the glyphosate-based herbicide groups significantly decreased from the 1st and 3rd week till the end of the study in groups B and C,respectively(P<0.05).There was a significant increase in the oestrous cycle ratio of the glyphosate-based herbicide groups compared to the control group(P<0.05).Though the estradiol and progesterone levels of the glyphosate-based herbicide groups increased and decreased,respectively,they were not significantly different from the control group.Conclusions:Glyphosate-based herbicide at the doses of 250 and 500 mg/kg can alter the pattern of the oestrous cycle in rats. | Hafsat Yazeed Idris Adewale Ayodeji Adeyeye Emmanuel Busayo Ibitoye Millicent Ladi Umaru | 2023 | Asian pacific Journal of Reproduction2023，12，3： | 0 |
| 3 | Policy and Implementation Mismatch:An Evaluation of Nigeria’s Compulsory Entrepreneurship Curriculum From Educational Management Perspective显示文摘In response to the increasing level of unemployment and the recent global trend of shifting individual economy prosperity from jobs to entrepreneurship and in the quest for fulfillment of the national goals of providing effective and self-reliant citizens,the revised National Policy on Education introduced 34 new entrepreneur/vocational subjects from which every student is mandated to pick one subject with the hope that she/he may practically apply as sustainable trade for self-reliance and possible personal economic prosperity.The educational administrators and managers at school level are further mandated to ensure a successful implementation of the curriculum.This study evaluates the curriculum 2007 using a census survey approach.Specifically,the most offered trade/entrepreneurship subjects were identified using a validated researcher made inventory and the questions of whether the subjects are relevant to the students’aspirations,the level of practical application of the trade learnt,and the level of quality of teachers handing the vocational subjects were examined through the administration of the instrument to 4,900 senior secondary school graduates,1,400 teachers,and 350 principals and directors in North-Western Nigeria.The study found four most prevalent subjects offered to be animal husbandry and fisheries,and it was also found that 71%of the teachers teaching the vocational subjects are not qualified to teach the subjects and the 71%of the students are not willing to practice the vocation learnt as trade.Among other things,complete revisiting of the curriculum 2007 was recommended where the subjects will be reduced from 34 to 10 through merger of many related subjects,and subjects like fisheries and animal husbandry should be merged with agriculture and the subject made compulsory. | Hafsat Abdullahi Umar | 2020 | Journal of Sociology Study2020，10，1： | 0 |
