Numerous erythrocyte indices have been introduced to help identifying thalassemia carriers with contradictory results. Therefore, this study had compared the use of mean corpuscular volume (MCV) and/or mean corpuscular hemoglobin (MCH) values and the most erythrocyte indices used in Indonesia which were Mentzer Index (MI) and Shine & Lal Index (SLI), as a first attempt in a mass screening for β-thalassemia carrier.METHODS: This was a retrospective study, evaluating laboratory data from family members of thalassemia major subjects. The sensitivity and specificity of MI and SLI were calculated. HbA2 >3.5% was used as a golden standard for β-thalassemia carrier and DNA examination was conducted to confirm β-globin mutation.RESULTS: Out of 160, 28.8% of the subjects had low Hb concentration. Interestingly, 79.4% of the subjects had low MCV and/or MCH with or without low Hb concentration. In this study, specificity and sensitivity of MI were 82.2% and 83.8%, whereas of SLI were 96% and 40.5%, respectively. Low MCV and/or MCH had covered IVS1nt5 and Cd26 mutation at β-globin gene; whereas MI and SLI had missed some samples, leading to false negative of thalassemia carrier results, when using MI or SLI only.CONCLUSION: MCV<80 fl and/or MCH<27 pg is the best first round mass screening method for β-thalassemia carrier in a limited facility area. However, Hb electrophoresis should be gradually installed regionally in various places wherever possible, as well as DNA analysis to confirm the mutation for an optimal carrier diagnosis.KEYWORDS: HbA2, HbE, iron deficiency anemia, Mentzer Index, Shine and Lal Index","PeriodicalId":22516,"journal":{"name":"The Indonesian Biomedical Journal","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77712593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Propolis, a natural resource that can be found in Indonesia, has been proven to have anti-apoptotic and antioxidant role which might be a potential adjuvant therapy for anthrax treatment. Hence in this study we aimed to investigate effect of propolis as an anti-inflammatory, anti-apoptotic, and antioxidant in anthrax rats model by examining the level of tumor necrosis factor (TNF)-α, caspase-3, and malondialdehyde (MDA), respectively.METHODS: This was an experimental post-test only study with 40 male rats weighed 180-200 g that were induced by anthrax spores injected subcutaneously. The rats were divided into one control positive group and four intervention groups that were administered with 200 mg/kgBW propolis extract for 7 to 14 days. The levels of serum TNF-α, caspase-3, and MDA were measured using enzyme-linked immunosorbent assay (ELISA) and analyzed with bivariate analysis.RESULTS: TNF-α, caspase-3, and MDA level were found lower in anthrax rats model given ethanol extract of propolis than the control group. The lowest concentration of TNF-α value was found in group administered with propolis extract 200 mg/kgBW for 7 days before the anthrax induction (6.136±0.205 pg/mL). The results were similar to the MDA serum and caspase-3 which were the lowest when the propolis was administered 7 days earlier (1.893±0.188 nmol/mL and 2.040±0.067 ng/mL). There was significant difference in the TNF-α, caspase-3, and MDA serum levels (p≤0.001) compared to control group.CONCLUSION: Propolis has anti-apoptotic and antioxidant effects which can be used as complementary therapy in anthrax infection.KEYWORDS: propolis, anthrax, anti-apoptotic, antioxidants","PeriodicalId":22516,"journal":{"name":"The Indonesian Biomedical Journal","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73656333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Caffeic acid has anti-inflammatory properties and can inhibit osteoclast bone resorption. In vitro studies have reported the ability of caffeic acid in inhibiting osteoclastogenesis pathways, however the in vivo study is rarely conducted. The aim of this study is to examine the role of caffeic acid in reducing inflammation and inhibiting osteoclastogenesis in Adjuvant-Induced Arthritis (AIA) rats.METHODS: Rats were injected with Freund’s Complete Adjuvant (CFA) and mineral oil. One day after injection, various concentration (0, 5, 25, 125 mg) of caffeic acid were given gastro-intestinally. Swelling degree in rats’ ankle joints was determined by measuring height and width of each ankle joint. Bone loss level was examined with soft X-ray, and then bone density was calculated. To examine osteoclastogenesis, ankle joints were stained with Tartrate-Resistant Acid Phosphatase (TRAP) and evaluated microscopically. RESULTS: Ankle joints of AIA rats had severe swelling before treated, yet the swelling was reduced based on concentration-dependent after receiving caffeic acid. Severe bone loss in AIA rats’ ankle joints were also observed, however the treatment of 125 mg caffeic acid showed remarkable inhibition effect toward rats’ bone loss. Osteoclastogenesis in AIA rats’ ankle joints were higher than the normal ones, as indicated with high TRAP-positive Multinucleated Cells (MNCs).

The involvement of metabolites, including lipids, amino acids, and ketone bodies, in altering insulin sensitivity has been revealed after massive data sets were provided by the studies regarding metabolomics and lipidomics.CONTENT: Metabolites were now understood to serve more than just the metabolism products, but also as active signaling molecules including in insulin and immunological actions. Different lipid metabolites can serve as signaling molecules to induce insulin resistance of sensitivity through a similar pathway, and impact on the inflammation status. Branched Chain Amino Acids (BCAA) and many amino acids have been correlated with mitochondrial dysfunction and insulin impairment. Ketogenic diet, supplementation and microbiota transplantation become the current strategies to set a preferable metabolites composition to modulate insulin sensitivity.SUMMARY: Thousands of metabolites can now be measured using technical and bioinformatics developments. Different types of amino acids, fatty acids, and bile acids are being studied in relation to altered metabolic states, particularly obesity and type 2 diabetes mellitus.

CD34+ cells are potential cells sources because these cells can differentiate into cardiomyocytes through several mechanisms. MicroRNA (miR-1) is known to have the ability to inhibit the expression of histone deacetylase 4 (HDAC4). HDAC4 is a gene that essentially contributes in cardiomyocytes differentiation. However, the study reporting an evidence that miR-1 can induce transdifferentiation of CD34+ peripheral blood cells into mature cardiomyocytes is limited.METHODS: CD34+ cells were taken from peripheral blood and isolated using a magnetic-activated cell sorting (MACS) method in vitro. Mature mimics of miR-1 were transfected into isolated CD34+ cells and then incubated for 48 hours for quantification of HDAC4 mRNA using reverse transcription-quantitative polymerase chain reaction (RT-qPCR). On the fifth day after miR-1 transfection, cardiomyocyte-like cells were identified based on their morphology and cardiac troponin expression using immunocytochemistry.RESULTS: Transfection of miR-1 in CD34+ isolated cells decreased HDAC4 gene expression by -0.54 fold at second day and caused a significant increase in percentage of cardiac troponin positive cells (median: 31.34; p<0.05) at fifth-day post-transfection. The efficiency of transdifferentiation was 32%. The miR-1 transfection had a significant negative relationship with HDAC4 gene expression (B=-1.000; p=0.001).

Therefore, in this study, we evaluated anti-inflammatory activity of B. lactis hydrolysates using lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages.METHODS: RAW 264.7 cells were cultured using Dulbecco’s Modified Eagle’s Medium in 5 % CO2 incubator at 37 ℃. One µg/mL of LPS was used to stimulate RAW 264.7 cells. Nitric oxide (NO) production, inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2) were measured to evaluate anti-inflammatory activity of B. lactis hydrolysates. The cytotoxicity of the inhibitor was also measured in present study through 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assay.RESULTS: The results showed that B. lactis hydrolysates at 25–200 μg/mL inhibited NO production.

A brief preliminary study indicated that A. malaccensis showed a promising immunomodulatory activity when evaluated using latex beads. This current study aimed to evaluate the immunomodulatory activity of A. malaccensis leaf extract on the macrophage, which was challenged with pathogenic bacteria Staphylococcus aureus.METHODS: Bioactivity was determined by evaluating the phagocytic capacity of macrophages isolated from Mus musculus against S. aureus. First, the cytotoxicity of extracts on macrophages was evaluated using MTT assays, and the IC50 value was used to determine the dose of immunomodulatory assays. The highest toxicity was observed on chloroform extract with an IC50 value of 111.4 µg/mL. Therefore, the treatment was 100 and 50 µg/mL. Two parameters, including the phagocytic activity and phagocytic capacity of macrophages infected with S. aureus, were used to evaluate immunomodulatory activity. The analysis of variance was done at p<0.05 to determine the significant difference among treatments.RESULTS: Chloroform and ethanol extracts at a 50 µg/mL concentration showed the best results with the phagocytic activity of 82.33%±9.61% and 80.33±1.53%. The ethyl acetate showed lower phagocytic activities of 70.67±1.53. All extracts significantly increased phagocytic activity and phagocytic capacity, and the results differed significantly between negative and positive controls. Thin-layer chromatography indicated that the extract contained terpenoid, flavonoid, phenolic, and tannin.CONCLUSION: A. malaccensis leaf extracts showed immunomodulatory activity.
