Abstract

Background: Immediate and accurate diagnosis of malaria is essential for effective control of this disease. Immunochromatographic based rapid diagnostic tests (RDTs) are economical, simple to perform, and provide results in a relative short time, can be useful to assist effective management of malaria. The commercially available malaria RDT in Indonesia is still imported. Therefore, an effort to produce malaria RDT independently is necessary. One of the biomarkers used in RDTs is Plasmodium lactate dehydrogenase pLDH. The production and accumulation of pLDH during asexual stage or blood-stage in all human infected malaria parasites can be used to indicate parasites viability, which is correlated with the number of parasites present in the plasma of infected patients. Objective: The aim of this research is to produce recombinant PfLDH in Escherichia coli BL21(DE3). Methods: PfLDH gene was cloned into pET30a expression vector to obtain a 6.2 kbp recombinant plasmid pET30a-PfLDH. E. coli BL21(DE3) was transformed with pET30a-PfLDH using the heat shock method. Then, E. coli BL21(DE3)- pET30a-PfLDH was cultured in LB broth containing 50 mg/mL kanamycin and was induced by 1mM IPTG at 37oC. Results: SDS-PAGE and Western Blot analysis showed that recombinant PfLDH was expressed with molecular mass ~30 kDa. Conclusion: Recombinant PfLDH is expressed in E. coli BL21(DE3) and can be used in further research for producing rPfLDH as a biomarker for malaria RDT development.

Abstract

Background: It is important to design a malaria vaccine targeting all human malaria parasites as well as non-human primate parasites to eradicate malaria and prevent zoonotic malaria. Apical membrane antigen 1 (AMA1) protein is shared by human-infecting Plasmodium species. Ancestral sequence reconstruction (ASR) and consensus sequence construction on AMA1 might be able to overcome the antigenic distinction between those species. Objective: We aimed to computationally design the ancestral and consensus sequence of Plasmodium AMA1 protein and analyze the sequences for its putative immunogenicity. Methods: We utilized bioinformatics software to computationally design ancestral and consensus sequences of AMA1 protein. AMA1 protein sequences of human-infecting Plasmodium and non-human primate Plasmodium were retrieved from PlasmoDB. ASR was designed using MEGA X while consensus was inferred using UGENE. Phylogenetic tree consisting of existing Plasmodium sequences and the ancestral sequence was constructed using IQTREE webserver and visualized with FigTree. Results: Phylogenetic analysis showed that Plasmodium spp. were divided into 2 major groups, P. falciparum (Clade F) and non-falciparum (Clade NF) thus three ancestral and consensus sequences were designed based on each clade and both clades at once. Reconstructed ancestral sequences were located as sister branch for naturally occurring strains. On the contrary, consensus sequences are located within the branch of corresponding naturally occurring strains. Sequence analysis showed the presence of CD8+ T cell epitope in all computationally-designed sequences. Conclusion: Ancestral and consensus AMA1 sequences are potential for further studies as a malaria vaccine candidate.

Abstract

Background: Breast cancer is one of the most common cancers as well as one of the leading causes of cancer mortality in women worldwide. Cancer risk potentially continues to increase because of the many sources of exposure to carcinogenic chemical compounds. Carcinogenic compounds can contribute to free radical formation which might further interact and damage biomolecules such as lipids. Lipid peroxidation will increase malondialdehyde (MDA) levels, triggering gene mutations that leads to cancer. Objective: The purpose of this research was to measure and compare MDA levels between breast cancer patients and control. Methods: This research was observational research using a cross-sectional comparative design of 30 breast cancer patients and 30 healthy controls. The place of this research is in Ropanasuri specialized surgery hospital and biochemical laboratory, Faculty of Medicine, Andalas University, Padang. This research was conducted from August to September 2019. The MDA was measured using a spectrophotometer and an independent T-test was done. Results: The result of this research showed the mean MDA level of breast cancer patients was 3.98 ± 0.35 nmol/ml, higher than controls was 3.04 ± 0.36 nmol/ml with p-value = 0.001. Conclusion: There were significant differences in MDA levels among breast cancer patients and control in Ropanasuri specialized surgery hospital, Padang.

Abstract

Background: Brain as a very aerobic organ is sensitive to hypoxia. Energy scarcities must be overcome by gluconeogenesis, which uses alanine or lactate as starting material. The reaction is catalyzed by alanine amino transaminase (ALAT or ALT), also known as glutamate pyruvate transaminase (GPT). Objective: To investigate whether the specific activities of alanine aminotransferase (ALT) increased in hypoxic rat brain. Methods: This experimental study used rats exposed to systemic normobaric hypoxia during 14 days. A group of 5 rats was sacrificed in days 1, 3, 7 and 14. The specific activities of ALT were analyzed in their brains using a reaction coupled with lactate dehydrogenase (LDH) activities. Results: The ALT specific activities in rat brain were very low. There was no significant increase of specific activities during long term hypoxia (p > 0.05). Conclusion: The rat brain ALT has no role in gluconeogenesis.

Abstract

Background: Lipoic acid is a substance contained in intra and extracellular that act as a coenzyme of Pyruvate Dehydrogenase, also as an antidote, chelating agent and antioxidant. Measurement of lipoic acid is needed to determine the amount of lipoic acid that performs its functions either as a coenzyme or an antioxidant. Besides, this measurement requires a special tool such as High Performance Liquid Chromatography (HPLC) and a process that is available in rural or simple laboratories. Objective: A common and easy tool such as a spectrophotometer was conducted and could expected to be a tool of lipoic acid determination in body fluid such as plasma. Methods: Measurement of lipoic acid using spectrophotometry with UV methanol and visible PdCl2 has been tested and compared to HPLC measurement that was valid and reliable in drug measurement or pharmaceutical preparations. Results: Determination of lipoic acid in plasma and leukocytes using PdCl2 produced replicable, reliability and valid result, with high accuracy, precision and was not different from lipoic acid measurement using HPLC, p=0.99. While UV methanol was different compare to HPLC p =0.0001 or was not valid. Conclusion: The measurement of lipoic acid using PdCl2 visible method can be applied to determine the levels of lipoic acid (LA) and DHLA in plasma and equal to HPLC result.

Abstract

Background: Psoriasis is a chronic inflammation of the skin caused by combination of genetic, immune and environmental factors. The Vitamin D receptors alongside with plasma vitamin D (25(OH)D) level have known to be related with psoriasis. Vitamin D receptor polymorphism is one of the multiple polymorphisms that predispose individuals to several diseases. It is possible that this polymorphism is different among psoriatic patients and healthy one particularly in Medan, Indonesia population. Objective: We aimed to investigate associations between plasma level of 25(OH)D and one VDR gene polymorphism (A-1012G) with psoriasis. Methods: Fourty four psoriatic patients and 44 healthy control subjects’ DNA samples were obtained in this case control study and genotyped for A-1012G polymorphism by Polymerase Chain Reaction (PCR). The plasma vitamin D (25(OH)D) level of case and control subjects were examined using Enzyme Linked Immunosorbent Assay (ELISA). Results: Significant lower plasma 25(OH)D levels were found in control group (p<0.001) which consist of mostly young adult female. There is no significant relationship between AA, AG and GG genotype variances of A-1012G polymorphism with psoriasis (p=0.124). Conclusion: No significant association found between A-1012G polymorphism and psoriasis but there was a significant difference found between vitamin D level and psoriasis (p<0.001). From this study, vitamin D deficiency were more common in young adult female.

Abstract

Background: The usage of cyclophosphamide leads to infertility of reproductive system caused by acrolein. Acrolein can itself cause oxidative damage by depletion of cellular glutathione (GSH) by conjugation, leading to membrane disruption, DNA and mitochondrial damage and can exacerbate apoptosis, which may affect spermatogenesis. Zinc (Zn) which is constituents of superoxide dismutase, has a protective effect towards free radicals from physiological or pathologic effects to minimize the cell’s damage. Objective: The purpose of this research was to know the effect of Zn on the spermatozoa count of Mus musculus that was given cyclophosphamide intraperitoneally. Methods: In the present study, cyclophosphamide was administered in saline 200 mg/kg 1x weekly for 5 weeks by ip route, whereas Zn was supplemented by oral route with doses of 25, 50, 100 mg/Kg/day for 5 weeks. The data were analyzed with Anova and followed by Bonferroni Test at a significant level of 5%. Results: The result of this research revealed that high Zn diet and Cp administration decrease sperm count simultaneously. It showed by the decrease of sperm count from 1490 (1 x 103)/ml sperm in the control group becomes 240 (1 x 103)/ml sperm in treatment group with 100 mg/kg of oral Zn and 200 mg/kg of cyclophosphamide. Conclusion: This research shows that Zn supplement to prevent cyclophosphamide toxic effect in spermatogenesis does not have a protective effect, in fact its reduce sperm count by excess of Methallothine production and alter the spermatogenesis by reduce Cu intake from intestine.

Abstract

Background: The kidneys in physiological conditions are always in a state of relative hypoxia. Cytoglobin (Cygb) is the newest globin protein found of the globin family. One of the functions of Cygb is in oxygen supply. Cygb expression is found to increase in hypoxic conditions, which are thought to be an adaptation response to hypoxia. Objective: This study aimed to analyze the expression of Cygb in rat kidneys which were exposed to chronic systemic hypoxia. Methods: Twenty five male Sprague-Dawley rats, weighing 150-200 g were used in this experiment. Rats were divided into 5 groups: The control group was exposed to normoxia; the hypoxia groups (10% oxygen / 90% nitrogen) for 1 day; 3 days; 7 days and 14 days. After treatment, rats were sacrificed and their kidneys were taken. Cygb mRNA expression was measured by qRT-PCR, while Cygb protein expression was measured by the ELISA method. Results: The expressions of Cygb mRNA and protein were found to be highest on day 3 of hypoxia and was correlated very strongly and significantly (r2 = 0.96; p <0.05). Conclusion: The highest expression of Cygb on day 3 of chronic systemic hypoxia exposure is suggested as an attempt to restore oxygen supply to the kidneys.
