Pangkilan Bare fish or Matano Medaka fish (Oryzias matanensis) is one of the most endemic species of freshwater fish that lives on Lake Matano. The purpose of this study was to determine the histopathology of the liver and intestines of the Matano Medaka fish contaminated by iron and nickel. The samples used were 6 fish with average size was 48.36 mm ± 0.74 mm. Samples were then processed with host technique analysis. Based on the results of this study obtained histopathological change that occurs in the liver and intestine in the form of hemorrhage, necrosis, fat degeneration, hydropic degeneration, lysis of hepatocytes and numerous melano macrophage. The results of measuring the water content of Matano lake contain iron (Fe) <0.03 mg / L and nickel (Ni) <0.07 mg / L. Therefore, the results of measurements of metal content in Matano lake sediments contain iron (Fe) 3.08% and nickel (Ni) 0.15%. The results of these measurements averaged above the threshold. Therefore, the high concentration of metals is thought to have a relationship with the abnormal tissue of fish organs observed in this study.
Background: The selection process in medical schools should be able to identify individuals that mostprobably will successfully complete their education. In Faculty of Medicine Hasanuddin University (FMHU)the selection processes are Seleksi Nasional Masuk Perguruan Tinggi Negeri), SBMPTN (Seleksi BersamaMasuk Perguruan Tinggi Negeri), JNS (Jalur Non Subsidi) and International students. Looking at the variousselection methods in FMHU, this study aimed to see how each selection method related with students’academic achievement.Methods: This study compared academic achievement in two semesters at three academic admission students(2014, 2015 and 2016), for four admission processes. The data consist of 308 students from batch of 2014, 308students from batch of 2015, and 320 students from batch of 2016. The analysis was conducted in descriptiveanalysis, One Way ANOVA, and followed by Post-hoc Bonferroni Test.Results: There was significant difference of students GPA for each type of admission. The highest academicachievement was obtained by students from International and SNMPTN admission while the lowest academicachievement was obtained by students from SBMPTN and JNS.Conclusion: Students from International and SNMPTN admission had the highest academic achievementcompared to SBMPTN and JNS. This study showed that there should be an evaluation of the assessment usedin SBMPTN and to continue the use of SNMPTN as one of the main admission route at FMHU.
Since its first emergence in China, the global spread of COVID-19 had reached 269.721.683 cases in over 200 countries in December 2021. The rapid spread of this virus had urged WHO and governments to establish policies on physical distancing. Restriction of offline learning activities in Indonesia forced the educational institution to rapidly adapt. As consequence, we had to change all learning and assessment processes into online forms. We found many challenges in the implementation, particularly in the assessment processes. Therefore, in consideration of Cognitive Load Theory, we decided to intervene in these problems by implementing multiple assessment strategies in Musculoskeletal System Course, for 2020 batch students. We compared the results of the 2020 cohort with the results of the 2019 cohort in the Musculoskeletal System using the Mann-Whitney test (SPSS version 24). There were 256 students (2020 cohort) who participated in this System in comparison to 318 students (2019 cohort). Statistical analysis showed that there was a significant difference between the outcomes of the 2020 cohort that experienced multiple assessments before final examination in comparison to 2019 cohort who only experienced single-end examination (p value <0.000). Mean outcomes of 2020 cohort (334.34) where significantly higher compared to 2019 cohort (240.96). Our study had shown that students’ outcome during online learning due to COVID-19 pandemic can be improved by chunking the volume of learning materials into several parts. This method was in line with Cognitive Load Theory and gave possibility for students to organize their learning as well as to get multiple feedback for their improvement.
Pleural effusion is a condition characterized by the accumulation of excessive pleural fluid in pleural cavity as a result of transudation and exudation. The most commonly reported cause of exudative pleural effusion is Mycobaterium tuberculosis. This study was aimed to identify Mycobacterium tuberculosis in pleural fluid through PCR test and to examine the relationship between PCR test and MGG staining of pleural fluid in patients with suspected tuberculous pleural effusion, which was performed in Clinical Pathological Laboratory Installation of dr. Wahidin Sudirohusodo hospital in Makassar and Faculty Research Unit Laboratory in Hasanuddin University from March to November 2012. This study was a cross sectional study. Subjects in this study consisted of 75 patients (41 males and 34 females[AA1] ) with average age of 40-49 years (30.7%). Pleural effusion patients with suspected tuberculosis who had a positive PCR result was 58.7%, negative PCR result was 41.3% and positive rivalta result in 82.7%, negative rivalta result in 17.3%. Statistical analysis using independent T-test indicated a non-significant relationship between PCR test and average MN and PMN cell percentage in MGG staining (P > 0.005). This study concluded that in MGG staining, average MN cell percentage was higher in PCR TB (+) group compared to PCR (-) group, but the difference was not significant.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
