Abstract

Cervical cancer is the second most common malignancy in Indonesia, and most of cases were already in advanced stage where radiotherapy is a tratement to given. Apoptosis is one of the markers for survival assessment of therapeutic response. In animal experiments MDM2 expression in various cell types to act as a survival factor by inhibiting the apoptotic function of p53 that is played by apoptosis can lead to malignant transformation and result in resistance to radiotherapy. Therefore, MDM2 is overexpressed due to alleged damage to p53 can also be used to assess the success of radiotherapy. This study aimed to assess the expression of MDM2 and p53 immunohistochemistry in cervical cancer and its relation to radiotherapy response. This study is a retrospective cross-sectional descriptive. The sample consisted of 23 cases of advanced cervical cancer were biopsied, 17 cases with complete response to radiation and 6 cases of partial radiation response. This study showed complete radiotherapy group MDM2 expression was found in 70.59% (12 cases) and p53 expression was found in 94.11% (16 cases), while the expression of MDM2, a partial response was found in 100% (6 cases), while the expression p53 66.67% (4 cases). MDM2 and p53 expression with SPSS 16 chi square test showed no association with response to radiotherapy in cervical cancer.

Abstract

Banana (Musa sp. - ABB) cv. Kepok is one of type banana processed that have a very potential commodities fruit developed to support food survival. The purpose of this study was to knowing the effect of gamma irradiation on the growth of banana plants cv. Kepok in vitro. This study was conducted in October 2014 – October 2015 in Plant Tissue Culture Laboratory, Biological – Science UNJ. The methods used was experiment with fully randomized design. Factors that tested was 6 gamma irradiation doses (0, 20, 30, 40, 50, 60 Gy) with 10 repetition. Observation of phenotypic generate diverse characters on the growth of the number of shoots and leaves. Gamma irradiation dose of 50 Gy is doses most inhibits the growth of character. Mutations that occur in banana plantlets cv. Kepok generated by the treatment doses gamma irradiation induced mutation is random.

Abstract

Birds are one of the animals that can be encountered utilizing City Park as a habitat. The existence of birds in a habitat influenced by factors such as life support shelter and feed availability. Situlembang Park, Suropati Park, and Menteng Park has a different characteristic. The purpose of this research was to observe differences in the structure of bird communities in the three parks. This study was conducted in January-March 2015 using descriptive method with point count technique. Results of the research the highest abundance of species in the Situlembang park is Pycnonoctus aurigaster, while bird species in Menteng Park and Suropati Park is Passer mountanus. The highest levels of bird diversity found in Situlembang park is 2,37 then Suropati Park (2.18), and Lowest Menteng Park (2.17). Bird species evenness index in the three parks is high (0.80 to 0.81) and and the dominance index is low (0.13 to 0.15) .The level in similarity index of bird species in the three parks is high (0,80- 0.88).

Abstract

Javan gibbon is one of an endemic species of Java with kind of unique vocalizations. Supported by a study which showed that every individual has the different anatomy vocal tract that will produce a different sound. Character vocalizations formed from the structure of vocalizations vary between individuals would be the identity of an individual so that there will be effective communication between the giver signal to the receiver. The objective of research is to find out the structure variation of Javan gibbon vocalizations.The research was accomplished in August-September 2015 at the Petungkriyono Protected Forest, Pekalongan, Central Java. The method used is the Focal Continuous sampling. Ratio coefficient of variation within and between female, indicates that the variable vocalizations vary between individuals, and the correct rate of individual identification yielded bydiscriminant function analysis using variable vocalizations was satisfactory (94,4%). Variable vocalization differentiatoris total great call duration (8,99-13,53 s), total great call duration excluding termination phase, duration pre-trill phase, duration introduction note (0,147-0,612 s), frequency range introduction note (408,54-1209,6 Hz), minimal frequency introduction note, maximal frequency introduction note, minimal frequency second trill note, minimal frequency at end of trill note, and minimal frequency range in trill. These vocalizations potentially allow individual recognition of animals.

Abstract

Hypertension is a condition of high blood pressure caused by many factors. One of them is endothelial dysfunction indicated from malondialdehyde (MDA) level. The production of MDA is primarily prevented by endogenous antioxidant such as superoxide dismutase (SOD). This study aimed to identify the differences between level of MDA and the activity of SOD in hypertensive and normotensive. It also aimed to identify the correlation between MDA level and SOD activity in both group. This study was conducted in laboratory of animal physiology FMIPA UNJ on June to September 2015. This research used an Ex-Post facto method with a cross-sectional design. A total of 30 serum samples (N1 = N2 = 15) was examined to identify MDA level and SOD activity. Data of MDA level and SOD activity was analyzed by Mann-Whitney test and t-test, respectively. Correlation between MDA level and SOD activity was analyzed by Pearson Correlation test in normotensive group and by Spearman’s Rho test in hypertensive group. Based on the results, mean value MDA level in normotensive was 0,465±0,118 nmol/mL and in hypertensive is 1,279±0,307 nmol/mL. MDA level in normotensive was significantly different than hypertensive (Sig.=0,000). Mean value SOD activity in normotensive was 2,307±0,739 u/mL, and in hypertensive was 2,131±0,422 u/mL. SOD activity was not significantly different in normotensive and hypertensive (Sig.=0,432). In conclusion, there was no correlation between MDA level and SOD activity in hypertensive and normotensive group.

Abstract

The aim of the study was to determine the correlation between sucrose intake at various administration doses to SGPT and SGOT level in Wistar rats. SGPT and SGOT level in blood serum were used as parameter of liver function. Twelve rats were grouped according to administration doses (20%, 40%, 60% of given feed total energy and control group). Sucrose was administered orally once a day for 70 days at given doses by force feeding. SGPT dan SGOT level were measured using SGPT and SGOT Test Kit and read using spectrophotometer. The result indicated that increased administration dose caused a significant increase of SGPT and SGOT level.

Abstract

Zoonosis from bats to human in urban areas is a problem that must be investigated.This study aims to determine the species diversity in Tangerang Selatan City and human perception of bats. The study was conducted in July 2015 to November 2015. Bats were caught by mist nets and harp traps. Traps was placed purposively based on bats traffic at each study site. There are 3 sampling locations, each location, has been done for 4 nights with 3 mist net. Bats are found in South Tangerang City consisting of 5 spicies, namely: Cynopterus brachyotis, Cynopterus horsfieldii, Cynopterus titthaecheilus, Macroglossus sobrinus and Myotis muricola, with an index of species diversity was (H ‘= 1.68). Human perception and behavior in relation to the spread of zoonosis are at high scores (> 75), which means that the perception of the bat can keep them away from a zoonotic disease caused by bat.
