Penyakit Periodontal Sebagai Penyebab Penyakit Jantung Koroner Di Rsup Dr. Kariadi Semarang

Background: Cardiovascular disease is a prevalent disease that occured on human population in this world. This disease was in second position in the most deadly disease after infection. One of cardiovascular disease that become prevalent lately in Indonesia was coronary heart disease. Coronary heart disease have many risk factors, one of them is pathological condition of artery blood vessel inner wall, that suspected by some doctors can be caused by bacterial activity from periodontal disease, a disease that most people think harmless. The previous researchs already suspected that there are relation from this two disease, but none of them can define the real realtionship, because of to many confound factors. The aim of this research is to find out wether there any conection beetwen periodontal disease and coronar heart disease or not.Methods: This was a descriptive-analytical research with Case-control approach, the samples are 35 coronary heart disease patienst, and 35 others heart diseases patient, all of the samples were treated in second and third class of Dokter Kariadi Hospital heart ward. The periodontal index was counted with classification from Russel.Result: Using Chi square test to analyze the characteristics of samples, it can be concluded that hipertension and oral health care have significant relation with coronary heart disease. And using Mann whitney test, it`s concluded that periodontal disease have significant relationship with coronary heart disease. But, because there are more than one variable that has significant relationship with coronary heart disease, we`re using Logistic-Regression test to excluded other confounding factors.Conclusion: There is a relation from periodontal disease and coronary heart disease, but there is confounding factor that is more dominant, it is hipertensio

Phylogenetic and functional marker genes to study ammonia-oxidizing microorganisms (AOM) in the environment

The oxidation of ammonia plays a significant role in the transformation of fixed nitrogen in the global nitrogen cycle. Autotrophic ammonia oxidation is known in three groups of microorganisms. Aerobic ammonia-oxidizing bacteria and archaea convert ammonia into nitrite during nitrification. Anaerobic ammonia-oxidizing bacteria (anammox) oxidize ammonia using nitrite as electron acceptor and producing atmospheric dinitrogen. The isolation and cultivation of all three groups in the laboratory are quite problematic due to their slow growth rates, poor growth yields, unpredictable lag phases, and sensitivity to certain organic compounds. Culture-independent approaches have contributed importantly to our understanding of the diversity and distribution of these microorganisms in the environment. In this review, we present an overview of approaches that have been used for the molecular study of ammonia oxidizers and discuss their application in different environments

Differences in the Effectiveness of Wall Pass and Short Pass Exercises in Physical Education Learning at SMP Negeri 1 Sumowono

The research is motivated by soccer learning which needs to be improved with wallpass and short pass exercises. The problem faced is how to determine the right model of passing practice for students. This can be seen from the two techniques proposed, namely the game and the wall pass and short pass. Both techniques are assumed to be able to improve the accuracy of passing through various previous research results. The purpose of this study is to provide information about exercises that can be applied in learning football. This type of research is experimental research using a quasi-experimental research design. The experiment was carried out in grades 7 and 8, with each sample of 25 students. The data collection technique with observations was carried out using a questionnaire and carried out objectively by the observer. The data analysis technique used in this research is a test technique. Hypothesis testing is done utilizing descriptive analysis of the average difference test. These results indicate that the group that was treated using the Wall-Pass (WP) method had a significant difference from the class that was treated using the Short-Pass (SP) method. Teachers can innovatively develop teaching tools for other passing methods to improve student learning activities. Students need to help each other if they experience problems in implementing the model, and the teacher must be able to ensure that each student in the group can achieve the goal or complete the assigned task
