Abstract

ABSTRACT Atherosclerosis is one cause of death. The thickening of the arterial walls which form atherosclerotic plaque can cause a blockage of the artery lumen and lead to thrombosis and blood flow. VCAM-1 activation causes increased adhesion of monocytes to endothelial walls and foam cell formation which is the key to the occurrence of atherosclerosis. Diplazium esculentum contains antioxidants and is able to inhibit the activation of VCAM-1. This study aimed to determine the effect of vegetable fern extract on the expression of VCAM-1 as an anti-atherogenic effect and the effective dose required. Experimental studies using randomized post test only control group design. Samples were grouped into 7 groups, namely K, KN, P1, P2, P3, P4, and P5. All group except K induced by atherogenic diet ang followed by the granting of vegetable fern extracts of 300 mg/kgBW in P1 groups, 600 mg/kgBW in P2 groups, 900 mg/kgBW in P3 groups, 1200 mg/kgBW in P4 groups, and 1500 mg/kgBW in P5 groups. The results showed a correlation between the dose of the extract given by the expression of VCAM-1, the greater the dose given VCAM-1 will be further hampered. The effective dose in rats was 2707, 19 mg/kg, this dose is equivalent to 4 kg of fresh vegetables fern in humans. Keywords: Atherosclerosis, Vegetable Fern Extract, VCAM-1  ABSTRAK Aterosklerosis merupakan salah satu penyebab kematian.

Abstract

Indonesia is still included in high endemic area of malaria infection. Early detection as well as appropriate and quick treatment is needed to be able to prevent and treat malaria in Indonesia. Laboratory examination using a microscopic method is still used as the gold standard to diagnose malaria cases. However, the morphology similarity of some Plasmodium species and the number of parasites that can be seen under microscopy causes malaria diagnosis become difficult if only relying on microscopy diagnostic method. The purpose of this study is to analyze the sensitivity and specificity of nested PCR compared to microscopic examination in diagnosing malaria cases. A cross-sectional study has been carried out in some areas of Indonesia and the microscopic analysis as well as nest PCR was done in Laboratory of Parasitology and Laboratory of Central Biomedical Faculty of Medicine, Universitas Brawijaya, Malang East Java Indonesia. A total of 149 blood samples from patients with clinical symptoms of malaria had been obtained from Sumatra, Sulawesi and East Java during December 2011 to December 2013. From 149 sample, 81.9% samples were diagnosed malaria positive by microscopy examination, whereas the PCR results showed that 90.6% of samples were positive. Nested PCR sensitivity is 97.5%, and microscopy 88.2%. Nested PCR specificity is 40.7%, whereas microscopy 78.5%. PPV and NPV for nested PCR are 88,2% and 78.5% respectively, and for microscopy are 97.5% and 40.7% respectively. Nested PCR has a higher sensitivity than microscopy in diagnosing malaria and is able to detect mixed infection better than microscopic examination. However, it is statistically less specific than microscopy examination.

Abstract

Malaria is a major infectious disease worldwide, and vaccination is essential for disease control. The Plasmodium falciparum Erythrocyte Membrane Protein-1 (PfEMP1) is a potential malaria vaccine candidate due to its involvement in pathogenesis. Injection of DBL2β-PfEMP1 recombinant protein in animal models induces IgG and CD4+ production and inhibits binding with host endothelial receptors. This study aimed to analyze the spleen immune response by measuring the white pulp diameter. The experimental study used Wistar rats (Rattus norvegicus) that were divided into four groups, a control group and three treatment groups, which were injected with 100, 150, and 200 μg of DBL2β-PfEMP1 protein. Injection was done thrice with three-week intervals (days 0, 21, and 42). On day 56, rats were euthanized, and spleens were prepared for histology examination. The white pulp diameter increased along with increasing the dose of protein. The ANOVA test showed a significant difference between groups (p=0.001). The posthoc Bonferroni test showed a significant difference between the control and the 150 and 200 μg groups and the 100 μg and 200 μg groups. In conclusion, the DBL2β-PfEMP1 recombinant protein injection increased the spleen white pulp diameter in Wistar rats, and the 200 μg dose resulted in the highest increase.

Abstract

Background: Intestinal protozoan infection is a problem faced by the global community at all ages. In toddlers, it can cause problems in the form of decreased nutritional status, which is often found in developing countries such as Indonesia. The purpose of this study was to determine the correlation between intestinal protozoa infection and the nutritional status of toddlers.Methods: An observational study with a cross-sectional approach was conducted in October–December 2022 on 45 children aged 12–59 months in Sucopangepok Village, Jelbuk District, Jember Regency, East Java, Indonesia using, consecutive sampling techniques and a total sample size. Nutritional Status was measured based on body weight to body length using the WHO Anthropometric Calculator. Stool examination used the direct smear method and modified Ziehl-Neelsen staining. Data was analyzed using the Cramer's V test. The p-value less than 0.05 was considered statistically significant.. Results: The incidence of wasted children was 15.6% and severely wasted was 2.2%. Intestinal protozoan infection had an incidence of 15.6%. The species detected were Giardia lamblia (6.7%), Cryptosporidium parvum (6.7%), and Blastocystis hominis (2.2%). Statistical analysis showed there was no correlation between intestinal protozoan infection and nutritional status (p= 0.441; r = 0.191).Conclusions: There is no correlation between intestinal protozoan infection and the nutritional status of toddlers. However, comprehensive collaboration between the government and the community needs to be improved, as well as healthy lifestyles for toddlers which also need to be encouraged to overcome nutritional problems in children under five  old and prevent intestinal protozoa infections.

Abstract

Malaria caused by Plasmodium spp is an important health problem, and vaccination could be essential for disease prevention. One potential protein candidate is the Duffy binding-like 2β (DBL2β)-Plasmodium falciparum erythrocyte membrane protein 1 (PfEMP1). The protein is responsible for malaria pathogenesis by mediating binding to intercellular adhesion molecule-1 (ICAM-1), a receptor on the host cells. This study aimed to investigate the acute toxicity of the DBL2β-PfEMP1 recombinant protein as a basis for developing a peptide-based malaria vaccine based on body weight and interleukin-6 (IL-6) concentration. The study used male and female Wistar rats, which were divided into treatment and control groups after two weeks of acclimatization. Rats in the treatment group were injected with 750 µg DBL2β-PfEMP1 recombinant protein, and the control group was injected with NaCl 0.9%. Any indications of clinical toxicity symptoms were closely monitored within 4 hours of injection up to 24 hours. Observations were conducted daily for 14 days and included body weight and toxicity symptoms such as rising fur, tremors, salivation, diarrhea, weakness, draping, excitability, twitching, and death. Blood was collected on days 5, 7, and 14 for IL-6 examination using the ELISA method. Rats were euthanized on day 14. Data were analyzed using an ANOVA test. There was no significant weight loss as well as weight gain and toxicity symptoms during 14 days after treatment in all groups. There was an increase IL-6 levels on day 14 in all groups. However, statistical analysis did not show a significant difference between the control and treatment groups (p>0.05). This study showed that the DBL2β-PfEMP1 recombinant protein has no acute toxicity in Wistar rats, implying its safety and potential as a peptide-based malaria vaccine.

Abstract

The binding of Plasmodium falciparum erythrocyte membrane protein 1 (PfEMP1) to Intracellular Adhesion Molecule-1 (ICAM-1) is a major pathological mechanism in severe malaria including cerebral malaria. The binding is mediated by PfEMP1-DBL2β domain. The study aimed to explore there combinant protein of PfEMP1-DBL2β domain of P. falciparum isolated from Indonesia. DNA was isolated from a severe malaria patient. The DBL2β domain was amplified using Polymerase Chain Reaction (PCR) with specific primer and cloned into the pJET1 cloning vector. The DBL2β recombinant protein was constructed from DBL2β-pJET1 clone using pET-30a expression vector and expressed in Escherichia coli BL21-DE3. PCR colony and digestion of plasmid clones using restriction enzymes were conducted to confirm cloning result, and the expression of recombinant protein was analyzed using Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis (SDS-PAGE). The expression of DBL2β-PfEMP1 domain is higher in pellet than in supernatant fraction. In conclusion, the DBL2β-PfEMP1 domain recombinant protein of P. falciparum isolated from Indonesia expressed as a ~66 kDa protein in full length. Keywords: DBL2β domain, Indonesia, PfEMP1, Plasmodium falciparum, recombinant protein.

Recently, the development of the malaria vaccine is conducted by recombinant technology, and the purification of the CIDRα-PfEMP1 recombinant protein is a pivotal step. This study aimed to determine an optimal condition to purify the CIDRα-PfEMP1 recombinant protein by affinity chromatography through imidazole and NaCl concentration. The purified recombinant protein was visualized using SDS-PAGE and its concentration was measured using Image J software and Bradford Assay. The data were analyzed using SPSS 26 software, and the Paired T-Test analysis was conducted to compare the concentration of purified recombinant protein from two different methods. The result showed that thetarget band of purified recombinant protein was 27 kDa. The thickest target protein band was observed in purified recombinant protein using 140 mM imidazole and 300 mM NaCl. The recombinant protein concentration using Image J software was 0.025 µg/µL, while the Bradford Assay was 0.56 µg/µL. The Paired T-Test analysis has a significance value of 0.010 (p<0.05), meaning there was a significant difference between the concentration measurement using Image J software and Bradford Assay. In conclusion, the optimized condition to purify the CIDRα-PfEMP1 recombinant protein by affinity chromatography was using 140 mM imidazole and 300 mM NaCl. It is suggested to measure the purified CIDRα-PfEMP1 recombinant protein concentration using the Bradford Assay method due to its convenience and sensitivity.

Abstract

Malaria vaccine is urgently needed to eradicate malaria. The complexity of Plasmodium sp life cycle and host immunity to malaria have become the forces for developing peptide-based malaria vaccines using recombinant technology. The CIDR1α-PfEMP1 (cysteine-rich interdomain region 1α of Plasmodium falciparum erythrocyte membrane protein 1) is vital in malaria pathogenicity, making it a malaria vaccine candidate. This study investigated the IgG and CD4+ responses generated after the CIDR1α-PfEMP1 recombinant protein immunization in Wistar rats. The rats were divided into a control group, injected with 0.9% NaCl, and a treatment group, subcutaneously injected with 150 µg of purified CIDR1α-PfEMP1 recombinant protein. Injection was conducted thrice with a three-week interval. Blood samples were extracted every two weeks after immunization. IgG and CD4+ concentrations were measured using ELISA. Data were analyzed using the independent T-test and Mann-Whitney test based on the data distribution. IgG and CD4+ concentrations increased along with the injection frequency. Significant differences between the control and treatment groups were observed in IgG concentrations after all injections and CD4+ level only after secondary II immunization (p<0.05). In conclusion, the CIDR1α-PfEMP1 recombinant protein induces humoral and cellular immune responses through increased IgG and CD4+ concentrations, making it a potential malaria vaccine candidate.
