Early-life period (≤ 1 month after birth) is critical for determining long- and short-term health of neonates. Composition of neonates’ gut microbiota varies greatly between individuals whose development is influenced by various factors including differences in maternal diet and lifestyle during pregnancy, related to population and ethnicity. Balanced microbial composition can create symbiosis among commensal microbes, immunomodulatory compound production, and subsequent immune response regulation. Unbalanced microbiota composition, characterized by more pathogenic organism, less diversity, and less resistance to disease, is called dysbiosis. Probiotic bacteria are a bacteria group contributing to the balance of neonates’ gut microbiota. Probiotic bacterial strains, such as Lactobacillus, Bifidobacterium and Streptococcus strains, are present in neonatal meconium microbiota. Meconium, a biological material formed during pregnancy, is a useful source of information in describing in utero microbial environment. This review aims to describe probiotic potential in profile composition of neonates’ microbiota meconium of multiple ethnicities as marker of neonates’ health level. Molecular-based sequencing method, such as Next-Generation Sequencing (NGS), is the preferred method for analyzing complex microbiota communities, such as gut microbiota. Neonatal meconium samples are collected and DNA extractions are carried out, then the target genes are amplified by PCR. The amplicons obtained are sequenced and characterized to determine the presence of potential probiotic strains in sample. Whether the probiotic strains can be used to measure neonates’ health level during period of growth and development is also described. Those probiotic strains could be developed as microbial therapeutic agent in gastrointestinal tract disorder therapy.

Archaea is an organisme with unique feature because of its ability to inhabit an extremophyle conditions. Our expeditions to Tangkuban Perahu, West Java aimed to obtain archaealstrains from the solfatara fields located in Domas crater. From the samples, we intended to culture Thermoplasma species growing around 55 Â°C below pH 2, which until now have not yet been fully characterized. We collected five samples from mud holes with temperatures from 52 Â°C to 57 Â°C and pH below 2. In serial cultures of up to 8 transfers in Freundtâ€™s medium we grew tetraetherlipid synthesizing Thermoplasma species as documented by phase contrast microscope. Total membrane lipid extracts were analysed by thin layer chromatography; the pattern matched total lipid extracts from Thermoplasma acidophilum DSM 1728 membranes. For confirmation, 16S rDNA identification performing PCR and sequencing were carried-out. Analysis using BLAST showed T. acidophilum identities as the highest similarity of 99%, followed by T. volcanium, also with99% similarity (ANKF776908 and ANKF776909). This is the first report of culturing cell-wall-less thermoacidophilicarchaea,in particular Thermoplasma species in Indonesian laboratories.

Isolation and Molecular Screening of Glucansucrase Gene Harboring-Lactic Acid Bacteria. Exopolysaccharides (EPS) have been possessed to be used in pharmaceutical, cosmetic and food industries. Lactic acid bacteria (LAB) produce a wide variety of exopolysaccharides and carries sucrase genes glucansucrase/glucosyltransferase (gtf) and fructansucrase/fructosyltransferases (ftf) for EPS production. In this study, the isolation and screening of EPS producing-LAB (EPS-LAB) were carried out on modified de Mann-Rogosa-Sharpe (MRS) agar medium supplemented with 10% of sucrose on LAB isolated from various unique sugar containing-foods and -beverages originated from local sources. Besides obtaining EPS-LAB, this study aimed to screen for gtf gene as well as to molecular identify strains by using PCR technique. Degenerate primer pairs DegFor and DegRev which targeted the conserved region of gtf genes catalytic domain were used, whereas LABfw and LABrv were used to molecular identify strains using 16S rRNA gene. An approximately 660 base pairs (bp) amplicons which targeted gtf gene were obtained from 13 out of 16 srains chosen. Result from PCR of 16S rRNA gene identification on gtf positive strains revealed that all strains were molecular identified as LAB after DNA sequencing analysis by using blastn. A rare EPS-producing LAB were obtain i.e. Weissella. Strains obtained in this study are potential sources for exploring novel sucrase gene/s and obtain unique EPS polymer product/s.

Mesenchymal Stem Cell (MSC) secretome has potential as a neuroprotective and neuroregenerative agent. It can have effects due to its paracrine factors, such as Brain Derived Neurotrophic Factor (BDNF) and Stromal-Cell Derived Factor-1 (SDF-1) which can be induced with hypoxia preconditioning. This compound may play a role in the treatment of neurological diseases. Stroke has become a neurological disease that contributes to high rates of mortality and morbidity worldwide. There have been several pre-clinical trials on animal stroke models using MSC secretomes from rats and humans, but no studies have been conducted on Non-Human Primate, such as Macaca fascicularis. This species has been widely used in biomedical research and part of it can be utilized for such studies which will reduce the cost of using human MSC. The results of this study, Umbilical Cord (UC)-MSCs of Macaca fascicularis have been successfully cultured and characterized in terms of phenotypic and differentiation. Hypoxia precondition was able to induce BDNF secretion up to 264 pg/mL and SDF-1 up to 666 pg/mL in the UCMSC secretome. Hypoxic preconditioning with 3% oxygen can induce the most optimal BDNF and SDF-1 secretion, compared to 1% and 5% hypoxia.

The SARS-CoV-2 papain-like protease (PLpro) is essential for viral replication and a promising target for drug discovery. This study explored the inhibitory potential of compounds from Indonesia herbals Butterfly pea flower (Clitoria ternatea L), Star fruit leaves (Averrhoa carambola L.), and Java plum leaves (Syzygium cumini (L.) Skeels) against PL pro through molecular docking and in vitro assays. The molecular docking method utilized the target protein PLpro (PDB ID: 7CMD), with the native ligand obtained from compounds identified in these plant extracts. The compounds were identified using the KNApSAcK database and analyzed for drug-likeness based on Lipinski's Rule of Five. The physicochemical characteristics affecting absorption, distribution, metabolism, excretion, and toxicity (ADMET) were determined using the pkCSM descriptor algorithm protocol. Validation was performed using the redocking method, achieving an RMSD score of 0.728 Å, which indicated validity (RMSD <2.0 Å). The results identified four ligands with the lowest binding affinities from these extracts: (-)-Epicatechin 3-O-gallate, folic acid, petunidin 3-glucoside, and ellagic acid, with binding scores of -8.6, -8.3, -7.1, and -7.1 kcal/mol, respectively. Prior to conducting the PLpro in vitro inhibition assay, a fluorescence-based inhibition assay was performed using Z-RLRGG-AMC as the substrate and GRL0617as the control inhibitor. All extracts were subjected to 70% ethanol maceration. The IC50 value of GRL0617 was 3.38 μM, while fluorescence tests showed that Java plum leaf extract exhibited the highest inhibition percentage at 66.10±3.22%. These findings indicate that all three plant extracts contain compounds capable of inhibiting PLpro activity.

Various therapeutic agents have been used to treat stroke. However, currently there is extensive exploration of new potential therapies for stroke involving novel signaling pathways and development of therapeutic agents through biotechnological approaches. This article examines the recent advances in stroke therapy using biotechnology-based drugs. We conducted a comprehensive search using specific keywords relating to Ischemic Stroke, ATMP, Peptide, Antibody, Stem Cells, and connected topics in the databases of Medline, Scopus, Web of Science, and Pubmed. The main focus of the selection criteria was on English-language literature that explored the relationship between Ischemic Stroke, ATMP, Peptide, Antibody, Stem Cells, and related factors. This article exhibits that numerous studies are being conducted and have demonstrated the use of biotechnology-based therapeutic agents for stroke, including tissue plasminogen activators, therapeutic peptides, microRNA, monoclonal antibodies, as well as stem cells. These therapeutic agents have not only been tested on test animals but have also been commenced to be tested in clinical studies or have obtained marketing approval for use in ischemic stroke patients. In conclusion, despite the limited number of approved drugs, advancements in biotechnology are poised to make them common adjunct treatments for stroke patients, not just for managing the disease but also for its cure and regenerative effects in survivors.
