Abstract

ABSTRACT The process of desecuritization of Islamic terrorism becomes an interesting thing to be studied in the study of International Relations. This study attempted to analyze the process of Obama in conducting the desecuritization of terrorism through his speech to the Islamic community and the world. The research used descriptive qualitative research method with two concepts, namely: speech act from Nicholus Onuf which is explain the built process of rules through language construction and desecuritization by Barry Buzan that’s explain how threats transfer into the public sphere. Both concepts can help to analyze the process of Obama conducting Islamic terrorism desecuritization. This desexuritization is related to Obama identity that’s close by the culture and environment of third world countries. This makes him have a better understanding of Islam than his predecessor. The analytical technique used in this study is to interpret the data through focusing Obama's discourse or speech. Keywords: Terrorism, Desecuritization, Speech Act, United States

Abstract

This research was conducted to determine the effect of Leucaena leucocephala leaf extract on the development of ovarian follicle cells of mice (Mus musculus). Twenty four female mice, 10 weeks old, were divided into 4 groups. The control group (P0) were given 0.9% NaCl and the treatment group P1, P2 and P3 were given 0.5, 1 and 1.5 g/ kg bw of Leucaena leaf extract, respectively. The treatments were administered daily for 15 days by gavage. After the treatment ended, all mice were dissected to collect the ovaries. Histological preparation of the ovaries used paraffin method and Hematoxylin-Eosin staining. Observations were made on the number of primary, secondary, and tertiary oocytes, and also De Graaf follicles and corpus luteum. Data were statistically analyzed using One Way ANOVA method. The results showed there were no significantly differences (P>0.05) on the number of primary, secondary, and tertiary oocytes, as well as De Graaf follicles and corpus luteum among the control and treatment groups. The mimosine content of Leucaena leaf extract was 0.87% (less than 1%) so it could not inhibit the secretion of Follicle Stimulating hormone by the pituitary gland. The doses of Leucaena leaf extract used in this research did not significantly affect the follicles development of mice ovaries. In this study, the mimosine content of Leucaena leaf extract decreased 91.8%.

Abstract

Leucaena leucocephala provides the highest amount of proteins compared to other greens. However, its use is restricted due to the content of mimosine, an antinutrition non-protein amino acid known to be toxic to animals. This study aimed to observe the effect of administration of more than 10% of processed Leucaena leucocephala leaf meal to the level of T3, T4 and the thyroid histopathology. In this study, Leucaena leucocephala leaves were soaked in distilled water for 12 hours. The processed of Leucaena leucocephala leaf meal was made into pellets containing 0%, 7.5%, 15%, and 22.5% leaf meal of total feeds respectively, and was fed to the rats during pregnancy and lactation. The level of triiodothyronine (T3) and thyroxine (T4), and the thyroid histological features were the parameters observed. The collected data were statistically analyzed by SPSS 20.0 for Windows using One-way ANOVA followed by Duncan Multiple Range Test to observe any significant difference among the 4 treatment groups (?=5%). Meanwhile, the presence of hyperplastic cells and follicle lumens filled with vesicles and colloids was descriptively analyzed by means of available literatures. The analysis of T3 and T4 level revealed that there was no any significant difference between the control and treatment groups. The epithelial cells of thyroid follicles in the treatment groups of P1, P2 and P3 showed hyperplasia and were detached from their respective basal membranes.

Abstract

Acrylamide is a contaminant compound found in several types of food containing carbohydrates and processed food through frying or roasting at high temperatures. Acrylamide compounds could cause the formation of oxidative stress which could lead to neurotoxicity. This oxidative stress could be minimized by administering the antioxidant vitamin C. This study was conducted to determine the mice cerebral cortex histology, the mice cerebellum histology induced by acrylamide and vitamin C supplementation, and the most effective dose as a neuroprotector. This study used a completely randomized design (CRD) with 4 groups, namely K + (acrylamide 12.5 mg / kg BW); K- (NaCl 0.9%); P1 (vitamin C dose of 0.26 mg/animal /day + acrylamide dose of 12.5 mg/kg BW); and P2 ((vitamin C dose of 0.52 mg/animal/day + acrylamide dose of 12.5 mg / kg BW) and 6 repetitions so that the number of mice used was 24. The acrylamide and vitamin C solutions were administered orally, and acrylamide given for 20 days, while vitamin C was given 3 days before acrylamide induction until day 20. Mice were dissected at day 21, brain organs were collected for histological preparations by the paraffin method and Hematoxylin-Eosin staining. The qualitative data obtained were analyzed by One Way ANOVA and continued with the Duncan test. The parameters observed were necrosis in pyramid cells and glial cells. The results showed that vitamin C at dose of 0.52 mg/animal/day significantly repaired the damage in pyramid cells and glial cells induced by acrylamide.

Abstract

Indonesian local chicken is one kind of germplasm that has been utilized by the community for various needs, such as consumption, ceremonial, collection, and cockfighting. To maintain its sustainability, an inventory of genetic diversity can be made using molecular markers. This study aimed to determine the genetic diversity and relationship between four Indonesian local chickens: ayam kampung, ayam ketawa, ayam kate lokal, and ayam bekisar kangean, based on RAPD marker. DNA was extracted from blood samples of 12 local chickens consisting of 3 ayam kampung, 3 ayam ketawa, 3 ayam kate lokal, and 3 ayam bekisar kangean using Genetic DNA Mini Kit (Tissue) Geneaid. The PCR-RAPD analysis was performed using 6 primers, OPA 04, OPB 08, OPB 12, OPC 16, OPH 01, and OPH 03. The product of PCR-RAPD was electrophoresed using 1,5% agarose in 1x TAE buffer. The results showed that the similarity value of 12 local chickens using RAPD ranged from 0% to 100%. The relationship between 12 local chickens using RAPD marker indicated that the chickens in the same morphology were not clustered in the same group. This suggests that the same group of chickens phenotypically does not necessarily have the same genotype. Keywords: Local Chicken, PCR-RAPD

Abstract

The antioxidant contained in kersen (Muntingia calabura L.) leaves has been known to be able to prevent animal tissue damages. Monosodium glutamate (MSG) is a food additive substance associated with histological damage of duodenum as well as increases secretion of HCl in stomach if consumed in excess amount. This study aimed to investigate the histological features of stomach and duodenum of monosodium glutamate-induced mice (M. musculus) after treated with kersen leaves extract, as well as establishing its optimum dose. This study used a Completely Randomized Design, with 25 male mice assigned to 5 treatment groups: 2 control groups i.e. negative control (K-) given aquades and positive control (K+) given 0.7mg/body weight MSG; and 3 intervention groups which were given kersen leaves extract as much as 0.075 mg/g bw (P1), 0.15 mg/g bw (P2) and 0.3 mg/g bw (P3). Both kersen leaves extract and MSG was administered orally once daily for 28 days. The parameters observed were histological features of stomach features (erosion of villi and inflammatory cells infiltration) and duodenum (erosion of villi, necrosis, and inflammatory cell infiltration). The results showed that all parameters observed in the aforementioned organs were significantly different (P<0.05) in intervention groups (P1, P2, dan P3) compared with positive control (K+). It is concluded that administration of kersen leaves extract improved the damages of stomach, duodenum, and liver of MSG-induced mice, and was best achieved at the dose of 0.3 mg/g bw.
