Antimicrobial Resistance and Molecular Identification of Clinical Multi-Drug Resistant Enterobacter Cloacae
Enterobacter cloacae is a Gram-negative bacteria causing nosocomial infections. This bacteria has increased resistance to various antibiotics in the past five years, resulting in a multi-drug-resistant (MDR) phenotype. In particular, MDR E. cloacae causes longer hospitalization time, increases medical costs, and affects morbidity and mortality. This study aimed to observe the minimum inhibitory concentration (MIC) of clinical E. cloacae towards several antibiotics and molecular identification of MDR E.cloacae. This study was conducted in a descriptive design. Secondary data was collected at the microbiology laboratory of the Teaching Hospital in Bekasi, Indonesia, from May to September 2020. Sampel was carbapenem resistant E.cloacae. The isolate was originated from a human clinical specimen, then was confirmed molecular identification using 16s rRNA. In this study, only one carbapenem-resistant E. cloacae, which is also MDR bacteria, was found. This E. cloacae was categorized as MDR bacteria since it was resistant to more than three antibiotic classes, including carbanemen, extended-spectrum cephalosporin, penicillins + β lactamase inhibitor, antipseudomonal penicillins + β lactamase inhibitor aminoglycoside, and penicillin. Vitek 2 identification of this isolate was E. cloacae complex. It showed similar results to molecular identification based on a partial sequence of 16s rRNA. BLASTn result of the trimmed sequence was E. cloacae with 99.78 % similarity
Polyploidy Induction of Rutaceae through Bio-catharanthine Treatment
Indonesia has a tropical monsoon-type climate which suitable for agriculture and plantations. One of the main centers of orange fruits (Citrus sp.) production in Indonesia and become the top ten with the largest production is in South Sulawesi. Farmers commonly cultivate siam oranges (Citrus nobilis). Lime (Citrus aurantifolia) has not yet become the main production, which is inversely proportional to the high demand in South Sulawesi. This study aims to determine the ability of bio-catharanthine as a polyploidy agent against the phenotype of the familia Rutaceae cultivated in South Sulawesi. The research was carried out in Laboratory of Genetics and Molecular Biology, Department of Biology, Universitas Islam Negeri Alauddin Makassar using randomized complete block design consisted of two conditions (bio-catharanthine concentration including C1 = Bio-catharanthine 0.05%; C2 = Bio-catharanthine 0.075%; C3 = Bio-catharanthine 0.1% and immersion time including T1 = 3 h; T2 = 6 h). Phenotypic observations include plant height, the number of leaves and nodes, the length of roots, and the number of roots per shoot. The results of the study showed that the bio-catharanthine immersion of 0.05-0.075% for 6 hours in Rutaceae had a significant effect on their phenotypic characters

The method of obtaining medicinal plants was mostly done by cultivation, as much as 58% of the processing methods, and the most common use of plants in medicine was boiling and drinking. Plant species that had the highest SUV value were Morinda citrofolia, Zingiber officinale, and Elephantopus scaber with SUVs of 0.8 each. The plant family that had the highest FUV value was Zingiberaceae (eight species), furthermore, the part of the plant that had the highest value was the leaf. The total of plant species that had the highest Fidelity level was 52. One of them was celery (Apium graveolens L.). The data obtained from this research was needed to create an inventory of medicinal plant species and their use by the community, so that traditional knowledge of medicinal plants could be documented and preserved
Comparison of the Chaetodontidae Mitochondrial Genome
The mitochondrial genome is useful for identification because the mutation rate of mtDNA is higher than nDNA. Previous studies have carried out many analyses on the mitochondrial genome of several species, the Chaetodontidae group. Fish in this group are biological indicator fish of coral reefs, so their molecular characteristics must be enriched to conserve these fish. This article aims to review several forms of the mitochondrial genome of the Chaetodontidae group of species, including: Chaetodon speculum, Chaetodon octofasciatus, Chaetodon wiebeli, and Heniochus chrysostomus. Data were collected qualitatively by reviewing previous research articles related to the Chaetodontidae mitochondrial genome. The review focused on the characteristics of each species' mitochondrial genome, including length, overall composition, tRNA, and non-coding region. Each species exhibits various features of the mitochondrial genome and is mapped in its phylogenetic analysis

In-silico Approach for The Prediction of Chlorogenic Acid as PPAR-γ Activator
Coffee is one of the essential crops commonly cultivated in Indonesia. Coffee contains diverse bioactive compounds, which are associated with human health benefits. One of the compounds is Chlorogenic acid, which able to decrease the risk of type 2 diabetes mellitus (T2DM). However, the mechanism of chlorogenic acid toward anti-diabetes still unclear. This study aimed to analyze and investigate the potential role of chlorogenic acid as anti-diabetes through their interaction with Peroxisome proliferator-activated receptor gamma (PPAR-γ) as an enzyme to phosphorylate and regulate the mechanism of T2DM. The physicochemical properties of chlorogenic acid also performed in this study. The PPAR-γ was downloaded from the PDB database, and the chlorogenic acid was retrieved from the PubChem database. The protein and ligand were prepared using the PyRx program and were docked using Hex 8.0.0 software. Discovery Studio client 4.1 software was used to analyze the interaction between chlorogenic acid and PPAR-γ protein. Based on the physicochemical properties, chlorogenic acid is highly permeable to the cell and easily absorbed. Thirteen amino acid residues of PPAR-γ (GLN410, SER394, ASP396, GLY395, GLU407, LEUA401, LEU400, VAL403, LYS373, LYS438, LEU377, LYS434, and GLY437) were identified on the chlorogenic acid-PPAR-γ interaction. Interestingly, the kind of interactions, including hydrophobic interaction, hydrogen bond, and van der Waals, which are supported by the tight interaction. Our study indicated that chlorogenic acid might have anti-diabetes activity through PPAR-γ interaction.
 
Curcumin Effectivity on Hepar and Reproductive Organ Recovery Male Mice (Mus musculus L) after Methoxychlor Exposure
Methoxychlor (MXC) is an insecticide (DDT derivates) that has the potential for bioaccumulation in mammal and causes a disruptive effect on the hepar and reproductive system. This study was done to find out the benefits of curcumin as a natural ingredient to overcome the negative impact of Methoxychlor (MXC) on hepar and male reproductive organ of Balb’C mice (Mus musculus L). The study was carried out in a Completely Randomized Design (CRD) Posttest Only Control Group Design used four treatments and six replications. The curcumin treatment after administration of MXC was carried out by gavage with curcumin doses: 0.05; 0,1; and 0.2 mg/g body weight, every day for two weeks, respectively. Histological observations of the liver, and testis was performed using the paraffin method and Hematoxylin Eosin stained. The results showed that MXC exposure caused liver disruption by increasing the number of pycnotic necrotic hepatocytes and hydrophic degeneration hepatocytes. On the male reproductive organ, MXC caused testis impairment by reducing the number of Sertoli cells and Leydig cells, spermatogenic cell counts, and the diameter of seminiferous tubules. The administration of curcumin at doses of 0.1 mg/g bw in mice exposed to methoxychlor can reduce the number of hydrophic degeneration hepatocytes and tend to reduce the number of pycnotic hepatocytes; and also increase the number of Sertoli cells, the number of spermatogenic cells, and the diameter of the seminiferous tubules, and tend to reduce the amount of Leydig cells. Curcumin treatment tends to recover hepar dan testis disruption of mice that were exposed by MXC
