Background: Peptic ulcer is one of the most common gastrointestinal tract diseases which affect the stomach. This study aimed to determine the effect of aragi on the adult rats' stomach and investigate the effect of water as a therapeutic agent on aragi-induced ulcerations.Materials and methods: Thirty-five adult Wistar albino rats were used in this experimental study. Five rats were sacrificed on day 0, 5 rats were used as a control group, and 25 rats were treated with aragi. On day 15, all rats in the control group and five aragi-treated rats were sacrificed for histological examination of the stomachs. The remaining 20 rats were stopped from aragi intake and 10 of them were treated with water for 15 days. After 15 day, all rats were sacrificed for histopathological examination of their stomachs. Stomach tissues were stained using hematoxylin and eosin (H&E) and documented under a microscope.Results: Our research showed that aragi-treated rats had different severity of peptic ulcers after 15 days of continuous aragi intake, while the control group showed normal stomach histology. Nine out of 10 rats treated by water after aragi treatment also showed normal stomach histology.Conclusion: Aragi is a causative agent for peptic ulcer and water can be used as potential natural therapy for treating ulcerative stomach.Keywords: aragi, water, stomach, peptic ulcer

Background: High mutation rates in HIV-1 could affect the accuracy of diagnostic tests. Therefore, recombinant antigen that has an immunodominant and conserved region from HIV-1 need to be developed to detect HIV-1 infection in Indonesia.Materials and methods: The recombinant antigens comprise of Gag (p24), Pol and Env (gp41). Each antigens was expressed in the Escherichia coli expression system and purified using Ni-NTA chromatography. The reactivity of purified antigen against HIV antibodies was tested against a group of 50 HIV-positive plasma samples and 45 HIV-negative plasma samples in a recombinant immunoblot assay (RIBA) platform test. Moreover, 21 of 50 HIV-positive samples and 3 of 45 HIV-negative samples were also tested using HIV blot 2.2 to compare RIBA with a commercial western blot kit. Ten HBV-positive and 10 HCV-positive plasma samples were used to check cross-reactivity with HIV recombinant proteins in RIBA.Results: All HIV-positive samples (100%) tested with RIBA were reactive towards Gag (p24), Pol, Env (gp41). Otherwise, 3 of 21 HIV-positive samples assayed with HIV blot 2.2 were not reactive to Pol protein. All HIV-negative samples tested with RIBA and 3 HIV-negative samples tested with HIV blot 2.2 did not produce any bands of HIV antigens. Few HBV and HCV samples showed reactivity towards HIV recombinant proteins.Conclusion: Each recombinant protein, Gag (p24), Pol, Env (gp41), could be expressed and purified, as well as had reactivity to HIV-positive samples in RIBA test. Therefore, RIBA can be used as a diagnostic test to detect HIV-1 infection in Indonesia.Keywords: diagnostic, HIV-1, immunodominant, recombinant immunoblot assay (RIBA)

Background: Platelet concentrate (PC) has a short shelf life (5 days). Expired PC cannot be used for clinical purposes. PC is used for human platelet lysate (HPL) production, which was found to be more effective than FBS at increasing T47D cell proliferation. HPL production using expired PC has not been reported. This study aimed to investigate whether the use of HPL produced from expired PC (storage duration >5 days) can increase the proliferation of T47D cells in vitro.Materials and methods: Expired PC samples with a shelf life of 7 and 11 days were used to produce HPL via freeze/thaw method. pH, total protein content, glucose and albumin levels were measured. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was used to measure proliferation rate and doubling time of HPL-treated T47D cells.Results: After HPL production, the glucose level was influenced by the pH (p=0.003), and albumin level was influenced by total protein content (p=0.030). HPL stored for 7 and 11 days increased cell proliferation rate by 1.41 and 1.80 times higher than 10% FBS, respectively. HPL produced from expired PC did not cause morphological abnormality of the cells. In this study, the glucose levels affected cell proliferation (p=0.030). High glucose levels inhibited T47D cell proliferation.Conclusion: Expired PC can be used as a potential material for HPL production, since HPL produced from expired PC increases cell proliferation rate and shortens cell doubling time.Keywords: cell proliferation, human platelet lysate, platelet concentrate, thrombocyte, T47D

Background: Nicotine is metabolized to cotinine by cytochrome P450 enzyme, and this enzyme is involved in the activation of toxic and carcinogenic substances. The aim of this research was to assess the relationship between genetic polymorphism of CYP2A13 and lung cancer incidence in female passive smokers.Materials and methods: This research was a case-control study that involved 104 research subjects. Subjects were recruited through purposive sampling technique from 2 hospitals in Medan, North Sumatra, Indonesia. The case population consisted of female passive smokers with lung cancer and the control population consisted of female passive smokers without lung cancer. All research subjects underwent blood sampling for genomics DNA extraction and CYP2A13 genotyping by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Data was analyzed by conditional logistic regression by Epi Info 7.0 software.Results: Among 104 subjects, 26 (25%) individuals were heterozygous, 76 (73%) individuals were wild type, and 2 (2%) were mutant for the 257Cys allele. There was a significant correlation between CYP2A13 genotype and lung cancer incidence (p-value<0.05). Female passive smokers with CT genotype had 2.7 greater risk of developing lung cancer than those with CC genotype (wild type). The C allele had more frequency and 1.6 times higher risk of lung cancer compared to T allele with a wide confidence range (0.73–3.52).Conclusion: There was a significant correlation between CYP2A13 polymorphism and lung cancer incidence in female passive smokers.Keywords: polymorphism, CYP2A13, PCR-RFLP, female passive smoker, lung cancer

Background: The major significant factor that affected lung cancer development among female passive smokers is environmental tobacco smoke. Nicotine can be found in a never smoker population, such as a child whose father is a smoker. Lung carcinogenesis in never smoker populations is affected by nicotine metabolism by CYP2A6 gene, which encodes the main nicotine metabolizing-enzyme. The aim of this study was to assess the genetic polymorphism of CYP2A6 and its association with secondhand smokers among females who have suffered from lung cancer in North Sumatra population.Materials and methods: This study was a case-control study, composed of 53 case subjects and 46 control subjects that were involved through a purposive sampling technique from two hospitals in Medan. PCR-RFLP was used for the examination of CYP2A6 gene to determine the genotype. The data were analyzed with conditional logistic regression test using Epi Info 7.0 software.Results: The most common genotype of CYP2A6 detected in this study was *1B/*1B (40.4%), while *1B allele had the highest prevalence (55.5%). There was no significant association between CYP2A6 genotype (p-value=0.61) or alleles (p-value=0.25) and the incidence of lung cancer.Conclusion: There was no association between CYP2A6 polymorphism and the incidence of lung cancer in secondhand smoker females.Keywords: CYP2A6, PCR-RFLP, female secondhand smokers, lung cancer

Background: Preeclampsia remains as the leading cause of maternal-neonatal mortality and morbidity worldwide. Vascular endothelial growth factor A (VEGF-A) is a proangiogenic factor related to endothelial dysfunction and plays an important role in the preeclampsia pathophysiology. Genetic variants of VEGF-A are associated with VEGF-A expression and preeclampsia risk, however there are still inconsistent results between different populations. The aim of this study was to determine the association of this genetic variant as preeclampsia risk factor.Materials and methods: A cross-sectional study was performed with 76 pregnant women (29 preeclampsia and 47 normotensive) Jambi-Malay ethnic subjects. Sample DNA was extracted from subject’s blood. To determine the genotype, one-step tetra amplification refractory mutation system (ARMS) polymerase chain reaction (PCR) method for VEGF-A rs699947 C/A was used.Results: We found that pregnant woman with AC genotype (p-value=0.045; OR=2.76 ; 95% CI=1.01-7.58) and AA genotype (p-value=0.026; OR=12.44; 95% CI=1.23-126.18) had higher risk of preeclampsia than the CC genotype.Conclusion: Genetic variant VEGF-A rs699947 C/A is associated with preeclampsia. The AC and AA genotype is the risk genotype for preeclampsia in Jambi-Malay ethnics.Keywords: preeclampsia, VEGF-A, genetic variant, Jambi-Malay, Indonesia

Background: Glutathione (GSH) is a principle thiol-containing tripeptide (cysteine, glutamic acid and glycine) antioxidant against free radicals and other harmful oxidants in cellular defence. The alpha-2-macroglobulin (α2M) is large tetrameric zinc-binding glycoprotein which inhibits proteinases regardless of their specificity and catalytic mechanism.Materials and Methods: The interaction of GSH was analyzed with α2M including the structural and functional alterations in α2M using various biochemical and biophysical methods. UV-visible and fluorescence spectroscopy were used to study the binding of α2M with GSH and Fourier transform infrared (FT-IR) spectroscopy was explored to study the structural change induced in α2M.Results: The results suggest that exposure of α2M to GSH decreases the antiproteolytic potential as suggested by the amidase assay. The UV-spectroscopic study showed the formation of α2M-GSH complex and fluorescence analysis showed significant quenching in fluorescence intensity of α2M suggesting GSH binding and structural alteration in the protein. FT-IR spectroscopy was explored to study the structural change induced in α2M which suggest that the secondary structure of α2M changes upon complex formation.Conclusion: Our studies show that interaction of α2M with photoilluminated GSH results in functional and conformational changes of the protein.Keywords: glutathione, GSH, alpha-2-macroglobulin, photo-illumination, ITC, FTIR

Background: Prostatic anomalies are common in tumor or infection condition. The enlargement of prostate gland affects the epithelial cell polarity that involves epithelial-mesenchymal transition (EMT). Transition into mesenchymal is mediated by transcription factor ZEB1 and E-cadherin protein. Upregulation of ZEB1 and loss of E-Cadherin expression were associated to proliferation and metastasis of malignancy cells. This study aims to describe the correlation of ZEB1 and E-cadherin expression in prostatic anomaly.Materials and method: Samples were Formalin Fixed Paraffin Embedded (FFPE) block consist of 8 block Benign Prostatic Hyperplasia (BPH), 6 blocks High Grade Prostatic Intraepithelial Neoplasia (HGPIN) and 6 blocks Prostate Carcinoma (PCA). The blocks then sliced into 5 sections to be prepared for RNA extraction procedures. ZEB1 and E-Cadherin expression was analyzed by semi-quantitative procedures using PCR and electrophoresis. Correlation between ZEB1 and E-Cadherin espression was analyzed using Spearman’s rank correlation.Results: Relative expression of ZEB1 and E-cadherin mRNA in each group of prostatic anomaly were not significantly different (p>0.05). ZEB1 and E-Cadherin mRNA expression showed a significant and moderate level of negative correlation (p<0.05; 0.40 < r < 0.59). Increasing of ZEB1 mRNA expression will be followed by decreasing of E-Cadherin mRNA expression.Conclusion: ZEB1 negatively correlates with E-cadherin due to EMT process in prostatic anomaly. High expression of ZEB1 induced down-regulation of E-cadherin and vise versa. Various studies can be developed, especially the development of targeted therapy against ZEB1 to suppress the EMT process by increasing the expression of E-cadherin.Keywords: epithelial-mesenchymal transition (EMT), ZEB1, E-Cadherin, BPH, HGPIN, PCA
