Abstract

The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), has spread worldwide and as a result, the World Health Organization (WHO) declared it a pandemic. At present, there are no approved vaccines against SARS-CoV-2. Therefore, the aim of this study was to predict epitope-based vaccines using bioinformatics approaches and phylogenetic tree construction of SARS-CoV-2 against the backdrop of the COVID-19 pandemic. In this study, we employed 27 isolates of SARS-CoV-2 spike glycoprotein genes retrieved from GenBank® (National Center for Biotechnology Information, USA) and the GISAID EpiCoV™ Database (Germany). We analyzed the candidate epitopes using the Immune Epitope Database and Analysis Resource. Furthermore, we performed a protective antigen prediction with VaxiJen 2.0. Data for B-cell epitope prediction, protective antigen prediction, and the underlying phylogenetic tree of SARS-CoV-2 were obtained in this research. Therefore, these data could be used to design an epitope-based vaccine against SARS-CoV-2. However, the advanced study is recommended for confirmation (in vitro and in vivo).

Abstract

Intervertebral disk (IVD) degeneration (IDD) is a degenerative disease and often found in daily practice.The managements that were used so far are only symptomatic and have not been able to solve the diseasecompletely. The use of mesenchymal stem cells (MSCs) has been widely tested as a solution for theregeneration of IVD in IDD. Adipose-derived mesenchymal stem cells (ASCs) are one of the sources ofMSCs which were widely studied as an alternative. One of the factors that can influence the efficiency andcapacity of ASCs in IDD cases is preconditioning. Generally, there were three pre-conditioning strategies ofASCs before being used as therapy, (1) modifying the environment, (2) using Growth Factors, Cytokines,Chemokines, Hormones, (3) using pharmacological and chemical agents. Preconditioning on ASCs canchange its function in various ways. We tried to link all these things together so that we could know the roleof pre-conditioning ASCs in the regeneration disk.

Abstract

Cellular transplantation using stem cells provides very promising solutions in the regeneration and repairment of cells that have experienced degeneration where recovery through medical or surgical intervension is impossible. However, the very low viability of transplanted stem cells limits the transplantation efficacy. The aim of this research was to obtain viable bone marrow derived stem cells by an adaptation treatment in a low oxygen tensioned in vitro culture. Low oxygen tension adaptation was adjusted to the niche of the stem cells in vivo. In this study, in vitro culture of stem cells in 1% oxygen was compared to those of the conventional culture in 21 % oxygen.Results showed that under 1% oxygentension cell proliferation was slower with larger or rounded triangle shaped cells, and senescence or dead cells was low. Meanwhile under 21 % oxygen tension cell proliferation was two fold faster with flattened and slender cells, and senescence or dead cells was higher. In conclusion, conventional in vitro culture under 21% oxygen caused cell aging (senescence) and rapid cell death, therefore the transplanted cells were not viable.

Abstract

Low back pain is a crucial public health problem that is commonly associated with intervertebral disc de‐ generation and has vast socio‐economic impact worldwide. Current treatments for disc degeneration are conservative, non‐surgical, or surgical interventions, and there is no current clinical therapy aimed at directly reversing the degeneration. Given the limited capacity of intervertebral disc (IVD) cells to self‐repair, treatment aiming to regenerate IVDs is a topic of interest and mesenchymal stem cells (MSCs) have been identified as having potential in this regeneration. Recent studies have revealed that the benefits of MSC therapy could result from the molecules the cells secrete and that play principal roles in regulating essential biologic processes, rather than from the implanted cells themselves. Therefore, the objective of this study is to review the potential use of the MSC secretome to regenerate IVDs. Current evidence shows that the secretome may regenerate IVDs by modulating the gene expressions of nucleus pulposus cells (upregulation of keratin 19 and downregulation of matrix metalloproteinase 12 and matrix Gla protein) and stimulating IVD progenitor cells to repair the degenerated disc.

Abstract

Mutations of precore (A1896) and core promoter (T1762/A1764) of hepatitis B virus can reduce HBeAg production. These mutations are frequently found in the late HBeAg seroconversion. However, it has been a controversy about the role played by precore and core promoter mutations in determining outcome of chronic hepatitis B. In the present study, the variability of precore and core promoter of hepatitis B virus were analyzed using PCR amplification and sequencing, according to the outcome (viral load and HBeAg/anti-HBe) in chronic hepatitis B patients in Surabaya. The study groups included 5 patients with uncomplicated chronic hepatitis B and 10 patients with chronic hepatitis B and liver cirrhosis in Dr. Soetomo Hospital, Surabaya. The control group included 6 blood donors obtained from Indonesia Red Cross, Surabaya. All groups were HBsAg positive. Precore mutation A1896 was predominant in all groups (60%-67% of each), together with precore variant T1858. As reported, precore variant T1858 is a prerequisite for precore A1896 and characteristic for viral genotype. Nevertheless, core promoter mutations T1762/A1764 were predominant only in LC patients (60%). All of these mutations were found mostly after HBeAg seroconversion (anti-HBe+). Of most samples with anti-HBe+, precore mutation was related with low viral load (<105 copies/mL), but core promoter mutations with high viral load (>105 copies/mL). Precore mutation A1896 was predominant in all groups, but core promoter mutations T1762/A1764 were only predominant in LC patients. The precore mutation alone is possible not critical to indicate a poor outcome, the core promoter mutations must be considered also.

Abstract

The pathogenesis of dengue virus infection is still being debated.  Based on the existing data, there is a strong evidence that the immunopathological mechanism plays a role in dengue virus infection with various complications.  Some unknown immune responses play a role in the pathogenesis of dengue virus infection. Researchers are trying to establish the role of several inflammatory mediators such as PLA2, IL-1, TNF-, PGE2, PGI2, Thromboxane A2, Leucotrien and MPTP, in relation to the severity degree of the dengue virus infection.  The aim of this study is to recognize the relation between the severity degrees of DHF (Dengue Hemorrhagic Fever) patients and the immunological profile in the sub-cellular level, such as PLA2, IL-1, TNF-, PGE2 and PLA 2.  The collected data was processed and presented analytically. The relation between each parameter (TNFα, SPLA2, PGE2,IL-1β) and the degree of DHF was analyzes, using Spearman's correlation analysis, ordinal regression, and using ANOVA.  It was shown that there was no relation between the levels of TNF-ά, PGE2, IL-1β, and SPLA2  in patients with various degrees of DHF, but there were significant differences between DHF grade 1 and 3, and also 2 and 3, on IL-1β.  There were increased levels of the four parameters in dengue grade 1 to 2, but decreased levels in grade 3. This can be caused by inflammatory processes, but the severity degree of DHF can also be influenced by complement, thromboxane, and leukotrien.

Abstract

Pendahuluan: Sebagai organ terluas yang menyusun tubuh manusia, kulit menjadi salah satu lokasi penting dalam menghantarkan obat atau bahan aktif tertentu ke dalam tubuh manusia. Beberapa bahan aktif berbentuk makromolekul dengan berat molekul lebih dari 500 Da tidak dapat menembus stratum korneum sehingga membutuhkan bantuan penetration enhancer. SPACE (Skin Penetrating and Cell Entering) merupakan rangkaian molekul peptida berukuran kecil yang berpotensi bekerja sebagai enhancer dalam menghantarkan makromolekul dengan cara yang tidak invasif. Namun SPACE merupakan enhancer golongan baru sehingga efek penambahan SPACE terhadap karakteristik dan stabilitas fisik pada formulasi sediaan gel masih belum banyak diketahui. Tujuan: Penelitian kali ini bertujuan untuk mengevaluasi efek pemberian SPACE pada karakteristik dan stabilitas fisik sediaan gel freeze dried Amniotic Membrane Stem Cell-Metabolite Product. Metode: Karakteristik fisik sediaan gel freeze dried AMSC-MP dengan SPACE dievaluasi menggunakan parameter organoleptis (warna, bau, bentuk, tekstur), pH dan diameter sebar sediaan. Stabilitas fisik sediaan akan dievaluasi dengan menguji karakteristik fisik sediaan selama 30 hari penyimpanan. Hasil: Gel freeze dried Amniotic Membrane Stem Cell memiliki pH sekitar 6,1 dan diameter sebar sediaan sekitar 6,0 cm. Seluruh hasil pengujian karakteristik masih memenuhi rentang yang dipersyaratkan. Hasil uji karakteristik dianalisis menggunakan statistika metode ANOVA satu arah dan tidak menunjukkan adanya perbedaan bermakna antar formula. Semua formula F1, F2, F3 dan F4 stabil selama 30 hari penyimpanan. Kesimpulan: Penambahan SPACE tidak mempengaruhi karakteristik dan stabilitas fisik sediaan gel freeze dried Amniotic Membrane Stem Cell-Metabolite Product.

Abstract

Pendahuluan: Amniotic membran stem cell metabolite product (AMSC-MP) merupakan metabolit produk yang diperoleh dari Amniotic membrane yang diisolasi dan dikultur yang kemudian ditumbuhkan dalam medium terkondisi. AMSC-MP mengandung banyak growth factor dan sitokin yang sangat berguna sebagai antiaging. Growth factor dan sitokin yang pada umumnya berukuran besar lebih dari 20 KDa menyebabkan AMSC-MP membutuhkan formulasi khusus untuk penggunaannya secara topikal. Pada penelitian ini digunakan asam hialuronat dikombinasi dengan SPACE peptide yang memiliki fungsi sebagai enhancer makromolekul untuk formulasi sediaan gel AMSC-MP sebagai antiaging. Untuk memastikan kualitas dan stabilitas suatu sediaan, maka perlu dilakukan uji karakteristik fisik dan uji stabilitas fisik sediaan tersebut. Tujuan: Mengevaluasi pengaruh penambahan asam hialuronat (0; 0,01; 0,02; 0,04 %) yang dikombinasi SPACE peptide terhadap karakteristik dan stabilitas dari formulasi sediaan gel AMSC-MP. Metode: Karakteristik fisik sediaan gel freeze dried AMSC-MP dengan penambahan asam hialuronat yang dikombinasi SPACE peptide dievaluasi dengan menggunakan parameter organoleptis (warna, bau, konsistensi dan tekstur), pengukuran pH dan kapasitas penyebaran. Pengujian stabilitas fisik dievaluasi dengan pengukuran pH dan kapasitas penyebaran sediaan setelah penyimpanan selama 28 hari. Hasil: Hasil uji karakteristik dan stabilitas fisik sediaan gel AMSC-MP menunjukkan penampilan fisik yang baik, gel transparan dengan konsistensi kental, lembut dengan bau yang khas. Nilai pH sekitar 5,26 - 5,37 dan kapasitas penyebaran pada 6,13 - 6,50. Semua formula stabil selama 28 hari penyimpanan. Kesimpulan: Penambahan kombinasi asam hialuronat dan SPACE peptide pada formulasi tidak merusak karakteristik dan stabilitas fisik sediaan gel AMSC-MP pada penyimpanan selama 28 hari.
