Appropriate Concentration of Curcumin as a Growth Factor in Neural Stem Cells
Get PDFThe growth of Neural Stem Cell (NSC) in adult organisms is limited. Therefore, growth factors are needed to stimulate NSC cell proliferation and differentiation. Herbal Curcumin may be a growth factor. We promoted the growth of Cryopreserved Rat Cortical NSC cells with Curcumin (0.1 µM; 0.5 µM; 1 µM; 2 µM), DMSO, and synthetic growth factors (bFGF, TGF, and heparin). We analyzed the proliferation ability of NSCs by WST-1 assay, cell morphology, and expression of NCS cell marker genes (Nestin, MAP, and Sox2). Morphological analysis showed that cells reproduced big77 optimally at 0.5 µM. The one-way ANOVA and Tukey's posthoc test on the WST-1 test showed significant differences between 0.5 µMCurcumin and other treatment groups. Sox2, MAP-2, and Nestin gene expression peaked at 0.5 µM. The appropriate concentration of Curcumin to stimulate NSC proliferation is 0.5 µM. Herbal extract curcumin has the same effect as commercial growth factors and can substitute synthetic growth factors. Curcumin acts as a growth factor that stimulates the proliferation of mouse NSCs
Detection of Papua New Guinea Thalassemia Alpha Mutation in Gayo, Sumba, Ternate, and Timika Populations
No full textAbstractPapua New Guinea (PNG) mutation is a point mutation that occurs in noncoding region of alpha globin clusters. Polymorphism promotes an additional recognition site for transcription factor (GATA-1) which presumably downregulates alpha globin synthesis. The aim of this research is to detect PNG mutation in other populations in Indonesia, thus the results will be used for completing standard diagnoses in detecting alpha thalassemia mutation based on ethnic background. The method used in detecting PNG mutation was PCR-RFLP. Detection of 399 samples (MCH5 hlm
Thalassemia Alfa Mayor dengan Mutasi Non-Delesi Heterozigot Ganda
No full textSeorang anak perempuan berusia 3 tahun dengan gejala klinis anemia berat,
hepatosplenomegali, dan memerlukan tranfusi darah teratur. Gejala klinis telah timbul
saat pasien berusia 3 bulan. Hapusan darah tepi menunjukkan gambaran hipokrom,
mikrositosis, dan anisopoikilositosis. Kadar HbA2 normal, HbF sedikit meningkat, dan
terdapat HbBart’s. Ayah dan ibu memiliki gambaran hematologis yang mendekati normal.
Analisis DNA menunjukkan dua mutasi non-delesi (mutasi titik) pada gen globin a2
yaitu pada kodon 59 (GGCglisin→GACaspartat) dan IVS2-nt142 (AG→AA). Kasus ini adalah
kasus pertama yang ditemukan di Departemen Ilmu Kesehatan Anak RS. Dr. Cipto
Mangunkusumo Jakarta yang mempunyai mutasi heterozigot ganda pada kodon 59 dan
IVS2-nt142. Gejala klinis thalassemia mayor diakibatkan adanya mutasi kodon 59 yang
menghasilkan varian hemoglobin yang tidak stabil (HbAdana) disertai adanya mutasi
non-delesi pada IVS2-nt142 yang menyebabkan proses mRNA yang tidak normal
Frequency of thalassemia carrier and Hb variant and the quality of stored donor blood
No full textBackground: This study was aimed to determine the frequency of thalassemia and Hb variant in blood donor. In addition, we also wanted to know the quality of blood from the donor up to seven days of storage, by calculating percentage of hemolysis in vitro.
Methods: This cross-sectional study was conducted on 138 blood donor specimens at Red Cross Blood Centre Unit in Jakarta. All specimens were tested for thalassemia and Hb variant by complete blood count (CBC) and Hb analysis with HPLC method and DNA analysis for the detection of α thalassemia carrier. To analyze the quality of stored blood, the calculation of hemolytic rate of red blood cells (RBCs) on whole blood (WB) was compared between the first and seventh days of storage.
Results: Out of the 138 specimens, 5 samples (3.6%) were diagnosed for α thalassemia carrier in which, one of them is co-inherited with ovalositosis hereditary (Southeast Asian Ovalositosis/SAO), 3 samples (2.2%) for β thalassemia carrier, and 3 samples (2.2%) for Hb E. Meanwhile, the hemolytic rates of RBCs on WB in first day and seven day of storage were below one percent.
Conclusion: The frequency of thalassemia carrier and Hb variants in blood donors at Red Cross Blood Centre Unit in Jakarta was 8%. The quality of stored blood until seven day of storage was quite good
Thalassemia carrier detection among pregnant women
No full textThalassemia major becomes the fifth catastrophic disease in Indonesia, however, national wide screening program is not mandatory. This study aimed to re-assess the validity of the various erythrocyte indices in determining ?-thalalssemia carrier among pregnant women in a low resource setting area. An analytic study was performed, comparing conventional cut-off various erythrocyte indices with new modified cut-offs by Kumar et al. The concordance analysis was calculated with Mentzer Index (MI) as reference. The validity of erythrocyte indices against hemoglobin (Hb) A2 were analysed, confirmed by molecular examination for ?- and common ?-Globin South East Asia population. Of 102 pregnant women, 34% was still anemic after completion of 90 iron pills. The concordance of conventional cut-off Shine & Lal index (<1530) was none to slight in agreement (kappa 0.097) to conventional cut-off MI (<13). The concordance of SLI increased significantly to substantial agreement when both used modified cut-offs (kappa 0.729). However, both SLI and MI had missed most of HbE carriers and ?-thalassemia carriers which seemed to be prevalent in this population as shown by DNA examination. In contrary, simple MCV<80fl and MCH<27pg had covered those carriers. This is the first study from Nusa Tenggara Timur, a low resource area in Indonesia in attempt to mass screen thalassemia carriers in this area where a simple MCV<80 fL and MCH<27pg have been used for preliminary screening rather than other indices. Since the population in eastern part of Indonesia has different genetic background compared to the west, DNA analysis is of great interest to map the spectrum of globin mutations

Potensi Penggunaan Materi Genetik Fetus pada Sirkulasi Maternal untuk Diagnosis Prenatal Noninvasif Penyakit Genetik
Get PDFDiagnosis prenatal adalah teknik diagnostik untuk menentukan kondisi fetus yang belum lahir apakah memiliki kelainan genetik ataupun kelainan lainnya. Teknik ini umumnya dilakukan pada penyakit genetik yang tidak dapat diobati di mana terminasi menjadi bahan pertimbangan. Teknik ini juga dilakukan pada kasus yang memerlukan penanganan segera pada saat prenatal dan pada kondisi yang dapat menimbulkan morbiditas atau mortalitas pada ibu. Diagnosis prenatal dapat dilakukan melalui metode invasif dan noninvasif. Metode invasif seperti amniocentesis dan biopsi villi korialis (CVS) memiliki resiko menimbulkan kecacatan bahkan kematian fetus. Pendekatan nonivasif melalui ultrasonografi belum cukup akurat untuk diagnosis penyakit genetik, sehingga masih memerlukan pengambilan sampel fetus untuk menegakkan diagnosis. Pendekatan terbaru pengambilan sampel fetus secara noninvasif dilakukan melalui pengambilan sel fetus, DNA dan mRNA fetus yang terdapat dalam sirkulasi darah maternal. Pada artikel ini dipaparkan mengenai perkembangan riset, kendala, serta potensi aplikasi klinis ketiga metode pengambilan sampel fetus tersebut.Kata kunci: diagnosis prenatal nonivasif, penyakit genetik, cell-free fetal DNA/mRNA, sel fetus.  [Potential Use of Fetal Genetic Material in Maternal Circulation for Prenatal Noninvasive Diagnosis of Genetic Disease].Prenatal diagnostic technique is used to determine whether the unborn fetus is affected with a genetic disorder or other abnormality. This technique is generally carried out for a genetic disease that is not treatable, in which the termination should be considered. This technique is also performed in cases that require immediate action during the prenatal period and in conditions that can lead to morbidity or mortality of the mother. Prenatal diagnosis can be done by invasive and noninvasive methods. Invasive methods such as amniocentesis and chorionic villus sampling (CVS) have a risk of causing disability and even death of the fetus. While noninvasive approach by ultrasound is not sufficiently accurate for the diagnosis of genetic diseases, therefore further  fetal sampling is required. Noninvasive prenatal diagnosis is a new type of genetic testing done through taking fetal cells, fetal DNA and mRNA, which are found in maternal blood circulation. In this review, we present development of research, constraints, and potential clinical applications of these three methods for noninvasive sampling of the fetus.Keywords: noninvasive prenatal diagnosis, genetic disease, cell-free fetal DNA/mRNA, fetal cell
