Abstract

Polymorphism or mutation in specific genes of P. falciparum and P. vivax is involved in the resistance to sulfadoxine-pyrimethamine (SP) antimalarial drug. On the other hand msp-2 gene plays an important role in drug resistance related genotyping. This study was undertaken as a basic information in assessing the urgent of development of malaria vaccine that can be created by ionizing radiation. Deoxy ribonucleic acid (DNA) of blood from malaria infected outpatients in Dok II Hospital of Jayapura for November 2014 period was amplified using nested polymerase chain reaction (PCR) and followed by restriction fragment length polymorphism (RFLP) analysis to determine the polymorphisms of SP resistance. Among 15 samples tested for dhfr gene, 9 (60%) and 8 (53%) samples showed positive result for polymorphisms in JR78/79 and F/108DH primers, respectively. For dhps gene by using JR84/85 and L/L primers 7 samples were positive mutant. These frequencies are lower compared to results of other research. Of these 15 samples examined, 3 had 3D7 alleles and 4 had FC27 alleles of the msp2 gene. No mutated S1105 and S1240 alleles and 6 mutant VDT alleles were found in P. vivax. It can be concluded that the resistance of parasites to SP was quite high, indicating the highly urgency to develop malaria vaccine.

Abstract

Akt is a protein that is associated with cell proliferation and is expressed at high levels in cancer cells. Some research indicates it may play a role in increasing the resistance of cancer cells to chemotherapy treatment. P53 is a tumor suppressor protein that influences the cell cycle and apoptosis. The purpose of this study was to examine the relationship between the expression of Akt and p53 in cancerous tissue before chemoradiation treatment, and the clinical response to treatment of cervical cancer patients. Twenty microscopic tissue samples were taken from cervical cancer biopsies obtained from patients before cancer treatment. The tissue samples were stained with p53 and Akt antibodies via immunohistochemistry technique, to measure expression of both proteins. After completion of chemoradiotherapy, patients? clinical response to treatment was determined using the pelvic control method. Our results revealed no correlation between expression of Akt and p53 index (P = 0.74) as well as between p53 Index and chemoradiotherapy clinical response (P=0.29). There was significant correlation between expression of Akt and cervical cancer chemoradiotherapy response (P = 0.03). There was no correlation found between p53 index and chemoradiotherapy clinical response (P = 0.29). High expression of Akt may related with high cell proliferation and resistance to chemoradiotherapy.

Abstract

Kanker servik merupakan penyakit kanker yang umum dijumpai pada wanita yang disebabkan oleh virus HPV (Human Papilova Virus). Tujuan penelitian ini adalah untuk mengetahui hubungan ekspresi protein MNK (Mitogen Activated Protein Kinase) pada penderita kanker serviks sebelum tindakan pengobatan terhadap respon kemoradioterapi. Sampel uji yang digunakan adalah sediaan mikroskopis hasil biopsi jaringan kanker dari penderita kanker serviks stadium lanjut (IIB-IIIB) sebanyak 20 sampel. Metode yang digunakan adalah metode imunohistokimia dengan menggunakan biomarker MNK pada biopsi jaringan kanker serviks. Ekspresi protein MNK yang positif ditandai dengan warna coklat tua yang terdapat pada inti sel. Respon kemoradioterapi diperoleh dari RSUPN Dr. Cipto Mangunkusumo Jakarta dan RS Hasan Sadikin Bandung. Hasil penelitian menunjukkan nilai IRS (Imuno Reaktif Score) protein MNK pada grup respon kemoradioterapi baik lebih tinggi dibandingkan grup respon kemoradioterapi buruk dan tidak ditemukan adanya hubungan IRS protein MNK dengan respon kemoradioterapi. Sedangkan hubungan ekspresi MNK terhadap respon kemoradioterapi menunjukkan adanya korelasi perbedaan grup respon kemoradioterapi antara ekspresi protein MNK negatif dan ekspresi protein MNK positifCervical cancer is a cancer that common in women caused by HPV (Human Papilova Virus).

Abstract

Radiation has a potent to damage cells. Radiation may act directly or indirectly on deoxyribonucleic acid (DNA) that results in the degeneration of tissues and necrotic, and thereby it needs a potent radioprotector to prevent these damages. Vitamin E is natural product known as an antioxidant which has potential as radioprotector. This research aimed to determine the capability of vitamin E with emphasized on the searching for its optimal concentration as radioprotector of DNA damage. This study used blood samples of healthy person irradiated with gamma rays at a dose of 6 Gy as the lethal dose to lymphocytes. The cocentrations of vitamin E from 0 to 0.8 mM was added into blood 15 minutes before irradiation. Isolation of lymphocytes was done using gradient centrifugation method. Evaluation on the capability of this compound in suppressing DNA damage was done by using alkaline Comet assay and data analysis was done using CaspLab program. The results show that addition of vitamin E could suppres these DNA damages and 0.8 mM of vitamin could reduce DNA damage up to 94.2%. We conclude that vitamin E effectively suppresed DNA damages induced by radiation. This information may benefit to the patient from negative impacts of radiotherapy.

Abstract

Malaria infection kills more than one million human every year, mainly under-5-year-old children, including in South East Asian nations. Gamma radiation given at a single dose is commonly used to create the attenuated Plasmodium parasites to get vaccine materials. However, there is no study on the infectivity of parasites after fractionated γ-radiation. This study aimed to assess the infectivity of parasites after irradiated with fractionated γ-rays in mice. A number of Plasmodium bergheithat was irradiated in two fractions of 100 and 50 Gy, 100 and 75 Gy; and 100 and 100 Gy within 5 minutes of interval time was injected intraperitoneally into 12 mice. Mice injected with unirradiated parasites (0 Gy) served as a control group. The parasitemia level of intraerythrocytic parasites in each group was observed at days post injection up to 20 days by making Giemsa stained thin blood smears and observed under the microscope. Results showed that fractionation radiation did not effectively attenuate the parasites where they still grew in blood of mice, except for 100+75 Gy. There are no significant differences among the treatment groups (p>0.05). This is different from irradiation at the single dose that resulted in almost completely attenuated parasites mainly the dose of 150 Gy. This implicating that irradiation of gamma rays at a single dose is a better way to mitigate parasites than fractionation dose as the infectivity of irradiated parasites were lower compared to that of fractionated dosage. Keywords: Malaria vaccine, Gamma radiation, Fractionation, Parasitemia
