Intraosseous Capillary Hemangioma of the Nasal Dorsum in an Adolescent
Hemangioma is a benign vascular tumor that commonly occurs in children, but its presentation on the nasal dorsum is rare, especially among adolescents. This case report describes a 16-year-old male patient with a progressively enlarging, painful nasal mass over seven months. Clinical workup including CT-scan, angiography, and FNAB revealed a vascular lesion suggestive of hemangioma. The patient underwent pre-operative embolization followed by surgical excision. Histopathological and immunohistochemical evaluations confirmed the diagnosis of intraosseous capillary hemangioma. Postoperative follow-up showed good aesthetic and functional outcomes with no recurrence. This report highlights the importance of comprehensive diagnostic and surgical approaches for managing rare hemangioma of the nasal dorsum to minimize complications and preserve facial structure

Evaluating Acute Toxicity of Jamu Cekok in Rats: A Histopathological Approach Based on OECD 425
Jamu cekok, an Indonesian traditional medicine to increase children appetite, has not passed preclinical or clinical trials. The rhizomes that make up jamu cekok such as pakai bahasa latinnya contain ethyl p-methoxycinnamate which is toxic, thus potentially harmful to the children. Therefore in this study we aim to determine the Lethal Dose (LD50) value of jamu cekok using the OECD 425 method as well as to observed the histopathological change in the liver in female Rattus norvegicus L. This study used an analytical experimental design with the OECD 425 method to test the acute toxicity of jamu cekok. The test rats used were in accordance with the OECD 425 protocol with an additional 2 negative control rats. Jamu cekok in the form of decocta were given once on the first day of the acute toxicity test and observed for 14 days. On the 15th day, rats were euthanized, dissected, and hepatic organs were taken to make histopathological preparations with Hematoxylin-Eosin staining. Analysis of hepatic damage was assessed using Histopathology Scoring Manja Roenigk and tested by Kruskal Wallis method. The results showed the LD50 value of decocta extract of jamu cekok was >5000 mg/kgBB. Observations of body weight, behavioral tests, organ index, and macroscopic hepar of test rats showed no signs of toxicity. However, The statistical analysis for histopathology test showed that there was a significant difference (p<0.05) between the negative control group and the 5000 mg/kgBB treatment group. In conclusion, the administration of jamu cekok was categorized as practically non-toxic but it can caused reversible hepatic damage at a dose of 5000 mg/kgBB
Isolation, Identification, and Evaluation of Antimicrobial of the LAB from Bekasam: The Traditional Fermented Fish in Indonesia
Lactic acid bacteria (LAB) are frequently utilized in fermented foods and can incresed shelf life for the products through their secondary metabolites includes carbon dioxide, hydrogen peroxide, lactic acid and bacteriocins. Beside increasing the shelf life, LAB also affect taste, smelt, and texture. Thus, this study aimed to isolate, identify and evaluate antibacterial LAB strains from Indonesian traditional fermented fish (Bekasam). Gram staining, the catalase assay, and motility assays were used to initially characterize the presumed isolates phenotypically following primary isolation on De Man, Rogosa, and Sharper (MRS) agar. 14 isloates were determined to be presumed LAB by preliminary phenotypic testing. One species that has the highest antibacterial activity is confirmed by a 16S rRNA sequencing study. Lactobacillus plantarum CP-134 was identified from the bekasam. In the biochemical characterization all isolates were catalase-negative and non-motile. According to our research, these LAB strains may have applications in fermented foods due to their probiotic properties, which include antibacterial activity. They might be used as natural substitutes for additives and antibiotics, but more in vivo or in silico research is required to verify their potential and effectiveness. A typical traditional food preservation technique for enhancing shelf life, food safety and nutrition and sensory qualities is fermentation. Bekasam is a traditional fermented food from Indonesia
Detection of The p53 Gene in Formalin Fixed Tissue Archives by Polymerase Chain Reaction (PCR) Method
Formalin fixed tissue archives are tissue biopsy results stored in formaldehyde fixative solution for a long time. The p53 gene is one of the genes that suppresses tumor occurrence and maintains genomic stability to prevent cell mutation and plays a role in the DNA regulation cycle and controls cell proliferation. Polymerase Chain Reaction (PCR) is a nucleic acid amplification technique used to denature and denature DNA or RNA using polymerase enzymes to detect the presence of the p53 gene in formalin-fixed tissue archival samples. This study aimed to detect the presence of the p53 gene in formalin-fixed tissue samples. This study used a descriptive research method with a random sampling technique conducted in the anatomical pathology laboratory and the National College of Health Sciences molecular biology laboratory. The samples in this study consisted of 10 samples consisting of 2 normal tissues used as controls and 8 formalin-fixed tissue samples. In this study, the p53 gene was detected in all samples, both normal tissue samples and formalin-fixed tissue samples after electrophoresis and visualized according to the target of 666 bp (base pair). The presence of the p53 gene qualitatively from DNA isolates can still be detected, but the gene expression level cannot be known in this study
Actinomycetes from Plant Rhizosphere in Gorontalo Karst Area as Plant Growth Promoting Rhizobacteria
This study aimed to describe Actinomycetes from the rhizosphere of plants in the Gorontalo karst area as Plant Growth Promoting Rhizobacteria (PGPR). The research method is based on a quantitative descriptive method. Soil samples from the rhizosphere were collected using a purposive sampling technique from 8 plant species at two locations in the Gorontalo karst region, namely the Tanjung Kramat Hills. The characteristics of PGPR in this study focused on phosphate solubilization ability, Indole Acetic Acid (IAA) production, antagonism against the fungus Fusarium oxysporum, and tolerance to fungicides. Potential PGPR isolates were analyzed for phylogenetic relationships based on 16S rRNA gene sequences. The results showed that there were 6 actinomycetes isolates (RzHKC-01, RzKO-02, RzO-03, RzAK-04, RzPK-05, and RzOC-06) from 8 plant species in the Gorontalo karst region. One actinomycetes isolate, RzPK-05, showed potential as a PGPR with the ability to solubilize phosphate and produce IAA at 0.165 mg/L and 0.133 mg/L, respectively. Isolate RzPK-05 exhibited antagonistic properties against Fusarium oxysporum with an inhibition rate of 82.24% and was tolerant to fungicides such as Captive, Benlate, and Thiramo up to a concentration of 100 mg/L. Molecular analysis based on the 16S rRNA gene and phylogenetic tree reconstruction indicated that the RzPK-05 isolate is closely related to the genus Streptomyces with 100% similarity

Soursop leaves (Annona muricata) are known as a plant that has the potential to treat breast cancer, which has a high mortality rate in women in Indonesia. The receptor that plays the most important role in breast cancer development is the Estrogen Receptor Alpha (ERa). This study aims to identify active compounds in soursop leaves that have the potential to inhibit breast cancer cell growth through in silico analysis using molecular docking of the ER? receptor using KNApSAck, PASS Online, PubChem, PDB ID, PyRx, and Discovery Studio software and Histochemical analysis was performed using fresh soursop leaves by making an incision on the lower part of the leaf and adding reagents AlCl, FeCl, Na2CO, CuSO4, glycerin, Wagner reagent, immersion oil, and ethanol, then observed microscopically. The in silico results showed the presence of specific compounds from soursop leaves and one reference compound (OHT600). Cis-Solamin had the highest binding affinity (-9.3 kcal/mol), better than the native ligand (-7.6 kcal/mol), and interacted with the amino acid Glutamine 532 (GLU532). Histochemical analysis showed the content of flavonoids, phenols, tannins, terpenoids, and alkaloids, accompanied by color changes in trichome and stomatal tissues. Based on the research data, it was concluded that soursop leaves can inhibit the growth of breast cancer cells through the content of secondary metabolites that actively inhibit Er? receptors
Molecular Method Optimization to Identify Plasmodium falciparum Multidrug Resistance 1 (pfmdr1) gene as a Predictor of Antimalarial Resistance
Several approaches have been designed to control malaria, a disease with high morbidity and mortality, but they face some hurdles. Antimalarial resistance is one of the major challenges for malaria elimination, so the detection of antimalarial resistance is essential. Several molecular markers for antimalarial resistance have been identified, including Plasmodium falciparum multidrug resistance 1 (pfmdr1) gene. This study determined the optimization of molecular techniques to identify the pfmdr1 gene as an antimalarial resistance predictor in Indonesia. The study included patients diagnosed with uncomplicated or severe malaria originating from the health district of Kerom Regency, Papua Province, and Dr. Soebandi Hospital, Jember, East Java Province. Blood samples were collected in the Whatmann filer paper after informed consent. DNA was isolated from dried blood filter paper, and nested PCR was performed using a specific primer, the pfmdr1-A and pfmdr1-B genes. The PCR cycle was optimized based on previous studies. The pfmdr1-A has a similar setting to the earlier study, but the pfmdr1-B had a different optimum setting from the previous study with the annealing temperature of 57oC for nested-1 and 62oC for nested-2. This PCR setting could be used for further examination. The positive results of the amplification indicated the potential for antimalarial resistance in the parasite population. A study on the gene copy number and polymorphism is essential to determine the definitive conclusion on antimalarial resistance
The Effect of Pilocarpine Hydrochloride on The Occurrence of Temporal Lobe Epileptic Seizures in White Mice (Mus musculus L.) BALB/C Strain
The objective of this research was to determine the effective dosage of pilocarpine hydrochloride to provoke epileptic seizures in animal models. In this study, a true-experimental method was utilized, employing a post-test only control group design. A total of 32 white mice (Mus musculus Linnaeus UICC 524) BALB/c strains were divided into four different groups for this study. The experimental groups were subjected to varying dosages of pilocarpine hydrochloride: 220 mg/kgBW as group I, 320 mg/kgBW as group II, and 350 mg/kgBW as group III. On the other hand, the control group was administered a saline solution (NaCl 0.9%) at a dosage of 0.16% ml/kgBW. Both pilocarpine hydrochloride and saline solution (NaCl 0.9%) were injected intraperitoneally (i.p) into mice. In group I, none of the mice experienced epileptic seizures, and they all survived. In contrast, in group III, all the mice experienced epileptic seizures, but none of them survived. The Man-Whitney Test showed significant differences in seizure occurrence across doses (p<0.01). The effective dose of pilocarpine hydrochloride for inducing epileptic seizures associated with temporal lobe epilepsy (TLE) in this study appears to be in the range of 320 mg/kgBW to 350 mg/kgBW
