Inside of this context, one of the major objectives of the CBME has been the scientific education  and  dissemination on Molecular  Biosciences.  Among the  strategies organized  to promote the dissemination of this area, the Scientific Dissemination Coordination of CBME developed a set of playful activities  for students from public and private  elementary schools (7th  and 8th grades).  As a first step science teachers were interviewed  in order to indicate  which topics related  to molecular bio- sciences they  usually  include in their curricula  planning.  The approach  considered  in the elaboration of the set of activities  was the construction of knowledge of the concepts related  to topics as cell types, their  structures and  organelles,  and  the  importance of the  nucleus and  DNA. The set was offered to170 students. Students from private  schools were evaluated by their  performance  through  the classes, which were registered  by the  notes  of the  instructors.  Students from public  schools were evaluated through  questionnaires containing  basic  concepts  on the  theme  applied  before (pre-test) and  after (post-test) the set of activities  in order to measure,  respectively,  the previous and acquired knowledge. The  programming accomplished  at  the  public  school was partially modified  due  to  the  absence  of a laboratory, microscopes  and  a room  of computers, without, however,  to  alter  the  objectives  and content of the  activities. The  comparative analysis  of the  pre- and  post-tests revealed  that, in this latter, there  was an increase of the average percentage  of correct  answers and an improvement on the elaboration of the  answers.  These  results  assure  the  efficiency of the program  and  the  methodology used.  The students considered the organization, contents and methodology  employed in the course as being satisfactory.

{"title":"Rapid identification of capybara (Hydrochaeris hydrochaeris) through allele-specific PCR","authors":"F. Henrique-Silva, Marcelo Cervini, E. Matheucci","doi":"10.16923/REB.V3I1.173","DOIUrl":"https://doi.org/10.16923/REB.V3I1.173","url":null,"abstract":"The capybara is the largest rodent in the world and is widely distributed throughout Central and South America.  It is an animal of economic interest due to the pleasant flavor of its meat and higher protein content in comparison  to beef and pork meat.  The hide, hair and fat also have economic advantages. Thus,  as an animal with such high economic potential, it is the target of hunters, even though  hunting capybara is prohibited by law in Brazil. Due to their  similarities,  capybara meat  is easily confused with  pork  meat. This  occurs  upon  the apprehension of the  meat  from hunters, as well as in some restaurants that serve capybara meat that was slaughtered clandestinely. In both cases, when the meat is confiscated, those responsible for the crimes claim it is pork meat,  hindering  the enforcement of the law. A practical  course was ministered  to undergraduate biology students enrolled in the elective course Introduction to Genetic  Engineering  at Federal  University  of Sao Carlos (UFSCar), Sao Paulo  State, Brazil.  The  objective  of the  course was to establish  and  apply  a Polymerase  Chain  Reaction  (PCR) assay to identify capybara meat and discriminate it in relation  to other types of meat,  including pork. Primers  were designed based  on 12S rRNA,  transthyretin and  growth  hormone  receptor  genes.  The primers generated  capybara specific fragments  of approximately 220, 290 and 330 bp for transthyretin,12S rRNA  and  growth  hormone  receptor,  respectively. The  duplexes  developed  in the  present work can be used effectively to discriminate capybara meat  from other  animals,  contributing to combating predatory capybara hunting. The results were extensively discussed and the students have contributed to written a paper  to be submitted to a publication.","PeriodicalId":185758,"journal":{"name":"Journal of Biochemistry Education","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129117832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The graduate students have to choose a subject for the discipline and, in 2003, the cho-sen subject was Nutrition and Sports: a Biochemical Approach, which is not specically broached inregular disciplines. The discipline was structured in the basis of collaborative learning, thus, the 75 en-rolled undergraduate students (from dierent courses as Nutrition, Sports, Pharmacy, Chemistry andBiology) were organized in small working groups. The students were given a study guide produced bythe graduate teachers (available in Portuguese at http://www.sbbq.org.br/revista/mtdidaticos.php),in which the following contents were covered: muscle contraction, O2 up-take, oxidative stress andanti-oxidant response, cramp, hydration, doping and nutritional supplies. In the nal activity thestudents had to evaluate critically myths and true facts in 80 statements usually associated to physi-cal activities and sports. The discipline was evaluated through questionnaires. From the analysis ofthe answers of both undergraduate and graduate/teachers students it is possible to conclude that thediscipline was well conduced and succeeded. These results emphasize the relevance and contribution ofthis kind of discipline to the pedagogical instruction of the graduate students and also to the increaseof undergraduate students interests in Biochemistry.","PeriodicalId":185758,"journal":{"name":"Journal of Biochemistry Education","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131291106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
