Abstract

Background: Bacterial resistance to antibiotics is still common due to unwise use. Urinary Tract Infections (UTI), 80% ofwhich are caused by E. coli and other bacteria such as Enterobactersp, Klebsiellasp, S. aureus. Phosphomycin is a first-line antibiotic for UTI. Combining natural compounds with antibiotics is one treatment strategy to increase the effectiveness of anti-bacterialt herapy. Andrographispaniculata has been reported to have strong anti-infectiveactivity. This study aimed to prove the differences in the germ number, leukocyte esterase levels,and urine procalcitonin levels in Rattus norvegicus UTI model given the phosphomycin, Sambilotoleaf extract, and Sambiloto leaf extract-phosphomycin combination. Methods: Thirty Rattus novergicus rats were divided into five groups. All groups were induced 50 µl of E. coli bacterial inoculum for 7 days, followed by standard feed (negative control), fosfomycin (Monuril®) 54 mg (positive control), Sambilotoleaf extract (S1 [100 mg/BW], S2 [200 mg/BW],Sambiloto leaf extract-phosphomycin combination (FS1 [sambiloto 100 mg/BW and fosfomycin 54 mg], and FS2 [sambiloto200 mg/BW and phosphomycin 54 mg]) for the next 7 days orally.The germ number, leukocyte esterase, and urine procalcitonin were measured after all rats were given treatment.  Results: The largest averagere duction in the germ number, levels of leukocyte esterase, and urinary procalcitonin (4.80 ± 3.70 CFU/ml [p<0.05], 3,00 ± 6,71 cells/µL [p<0.05], 4,66 ± 1,35 ng/L [p<0.05] respectively)was observed in the combination of 200 mg/BW Sambiloto leaf extract-phosphomycin combination group.  Conclusion: A combination of Sambiloto leaf extract and phosphomycin reduced germ number, levels of leukocyte esterase and urinary procalcitonin in rat model of UTI.

Abstract

Background: Prolonged hyperglycaemia can make the pancreatic beta cells work harder and cause fatigue. When this happens, it can trigger oxidative stress reactions, which can produce free radical compounds that can damage pancreatic beta cells. The body compensates by activating protective mechanisms such as the production of antioxidant compounds to reduce the levels of free radicals in the cells. One such compound is glutathione (GSH). Insulin Gaussia Luciferase (iGL) cells are a cell line derived from rat pancreatic β (beta) cells. These cells can be used as a model of oxidative stress in hyperglycaemia to measure GSH levels and there are no studies using iGL cells to measure GSH levels. Therefore, in this study, the iGL cells are used as the object of research.Objective: To investigate the effect of GSH levels on glucose toxicity condition through in vitro experiments on iGL cells.Methods: The study used 5 different glucose concentrations of 11, 16.5, 22, 33, and 44 mM with the addition of iGL cell growth medium exposed for 7 days. We measured the amount of intracellular GSH using a colourimetric method at a wavelength of 405 nm. The analysis used in this study was a one-way ANOVA test. Differences between groups were tested using SPSS.Results: The results of this study showed that there was an increasing trend in total GSH levels on the third and seventh day.Conclusion: there was a daily decrease in GSH/cell in the iGL sample cells exposed to different concentrations of glucose for 7 days. This can be due to an increase in the oxidative stress reactions in the cells, which can lead to a decrease in the levels of antioxidants.

Abstract

Background: Nutmeg is an indigenous plant from Indonesia that has been used extensively in herbal treatment. Nutmeg seed extract (NuSE) contains the active compound macelignan, which exhibits pharmacological activities. A previous study stated that NuSE is PPARγ or peroxisome proliferator-activated receptor gamma agonist that potentially enhances synaptic signal modulation. PPARγ activation can activate PGC1α or peroxisome proliferator-activated receptor gamma coactivator-1 alpha as the primary regulator of mitochondrial biogenesis. Mitochondria are involved in synaptic transmission. Increased modulation of signals at synapses can increase neuroplasticity, potentially improving the brain's cognitive function, as seen by the amount of Synaptophysin in the synaptic vesicle membrane for evaluating synaptogenesis.Objective: This research demonstrates how nutmeg seed extract (NuSE) affects PGC1α and synaptophysin expression compared with DHA or docosahexanoieac acid, which has been evidenced to promote neurite growth.Methods: Twenty-four Wistar male rats aged eight weeks were divided into four groups (control, PGA group, NuSE group, and DHA group). The treatment group was administered for 12 weeks using a gavage. After that, the rats were sacrificed, and the hippocampus neurons were collected. The PGC1α and Synaptophysin mRNA expression was measured using semiquantitative reversed PCR, visualized with electrophoresis, and then quantified with ImageJ.Results: This study showed that NuSE increased synaptophysin and PGC1α mRNA expressions compared to the control group with significance statistic (p=0.017, p<0,05) in synaptophysin expression but did not increase PGC1α expression significantly (p=0.364, p>0,05).Conclusion: In conclusion, nutmeg seed extract (NuSE) impacts synaptogenesis in synaptophysin expression to modulate synaptic transmission.

Abstract

ABSTRACTBackground: About 80% of cervical cancers are squamous cell carcinomas. After severe surgery for squamous cervical cancer, abdominal metastasis is an uncommon occurrence.Case Presentation: A 33-year-old lady was diagnosed with cervical cancer and had a radical hysterectomy, bilateral salpingo-oophorectomy, and bilateral pelvic lymphadenectomy. The histopathological examination showed non-keratinizing squamous cell carcinoma moderately differentiated. A 6 cm suggestive metastatic mass from abdominal region came up three months later after the surgery. An abdominal wall reconstruction surgery was conducted as the treatment for the metastasis mass.Conclusion: The best course of treatment for cervical cancer is still unknown due to the rarity of abdominal metastases. Depending on the severity of the illness and the existence of metastases, each patient receives a unique course of treatment.Keywords: squamous cell carcinoma, hysterectomy, cervical malignancies

Abstract

Background: Sunburn is an acute inflammatory skin condition caused by exposure to UV rays. Excessive exposure increases the production of  ROS which, if accumulated, can lyse growth factors, one of which is PDGF and also form IL-10 immune suppression. This condition can be influenced by providing antioxidants and anti-inflammatories such as those contained in sapodilla leaf extract (Manilkara zapota (L.) P. Royen) which has many benefits such as anti-inflammatory, anti-pyretic, anti-tumor, antioxidant, anti-microbial, anti- diabetic, anti-lipid and anti-aging. In previous research, the polyphenol content in Sapodilla leaves was a potential source of inhibiting ROS. However, until now the role of Sapodilla leaf extract on UVB burns has not been studied.Objective: The aim of this research is to determine the effect of administering Sapodilla leaf extract cream on PDFG and IL-10 in Wistar rats that experienced burns due to exposure to UVB.Method: Experimental research with a post test only control group design approach. This research used 24 Wistar rats exposed to UVB rays which were divided into 4 groups (normal control, control with cream, 25% Sapodilla leaf extract cream, and 50% Sapodilla leaf extract cream). The ELISA (Enzyme-Linked Immunosorbent Assay) method was used to analyze PDGF and IL-10 levels in skin tissue.Results: The highest ratio of PDGF levels was found in (K3) 2.915 ± 0.368. The results of the one way Anova analysis had a p value of 0.024 (p<0.05) which stated that there were significant differences between treatment groups. In IL-10 levels there was an increase in K3 255.9 ± 35,563. In IL-10, the results of one way Anova analysis had a p value of 0.240 (p>0.05), which stated that there were no significant differences between treatment groups.Conclusion: Administration of sapodilla leaf extract cream at a dose of 25% had a significant effect on increasing PDGF levels and a slight increase in IL-10 in mice that experienced burns due to exposure to UVB.

Abstract

Background: The recombinant Ag38 protein developed from a local strain of Mycobacterium tuberculosis has great potential to be used as a sero-diagnosis agent using the antigen rapid test because it has several epitopes that bind to antibodies. However, it is not yet known which antibody Ag38-recombinant binds maximally between IgA and IgG.Objective: The aim of this study is to compare the interaction between IgG and IgA on Ag-38 rec in silico as a basis for the selection of sero-diagnosis agents in the TB rapid test.Methods: The results show that the protein PstS1 has a higher binding sensitivity to IgG based on one of the docking models which shows a docking score of -229.70, a confident score of 0.8312 and RMSD 1.060 A. The ramachandran plot also shows that testing on this model has a protein structure that is good, with disallowed regions [X,X] values of 0.5% (less than 0.8%). The results of this analysis show that the most favored regions are 90.5% with a G-factor of -0.27. The quality of the structure of the 3D mooring model can be said to be good because it fulfills the ideal structure requirements.Conclusion: Ag38-rec antigen M. tuberculosis H37Rv binds to IgG more strongly than IgA.

Abstract

Background: Benign prostatic hyperplasia (BPH) is the most common prostate disease in elderly men that leads to a significant deterioration in patients' quality of life (QoL). Pharmacological therapy of 5-alpha reductase inhibitor and alpha adrenoreceptors blocker often causes several side effects that decrease the QoL, so it is necessary to develop a new treatment for BPH. Purinoreceptor is a novel receptor that can inhibit electrically evoked nerve-mediated contractions in the prostate. Tea leaves (Camellia sinensis) and Saw palmetto (Serenoa repens) are herbs that have potential as alternative therapies for BPHObjective: to reveal the mechanism of Camellia sinensis and Serenoa repens through purinoreceptor and the other receptorsMethods: Structures of active compounds were extracted from PubChem and protein from PBD. The active compounds Camellia sinensis and Serenoa repens to the target protein purinoreceptors, 5-alpha-reductase, and alpha adrenoreceptors was evaluated in silico using a docking server with Finasteride dan Tamsolusin as a control. Molecular docking method using dockingserver application.Results: Epigallocatechin gallate only compound that has potency in blocking purinoceptors and 5-alpha-reductase. Capric acid, Caprylic acid, Lauric acid, Linoleic acid, and Myristic acid have the potential to bind to alpha adrenoreceptor ligands.Conclusion: Camellia sinensis have potential and effects as alternative therapies in benign prostatic hyperplasia on the target protein purinoreceptors, 5-alpha-reductase, and alpha adrenoreceptors. But, Serenoa repens have potential only through alpha adrenoreceptors.

Abstract

Background: In recent times, meningitis, an infection primarily attributed to the zoonotic bacteria Streptococcus suis, has emerged as a significant public health concern in Bali, Indonesia. Their resistance to a multitude of antibiotics has emerged as a contemporary threat, as opposed to their virulence. There is a current lack of reported information regarding the genetic or phenotypic susceptibility pattern of S. suis to antibiotics in Bali.Objective: The objective of this research endeavor was to ascertain the antibiotic susceptibility pattern of S. suis isolates in Bali, either through phenotypic or genetic means.Methods: The Clinical Microbiology Laboratory of Prof. I.G.N.G. Ngoerah Hospital was consulted for the acquisition of clinical specimens. Since April 2016 until April 2022, the antibiotic sensitivity of isolates was identified and assessed using the VITEK 2 Compact (Biomeriuex®). Determining the serotype and antibiotic resistance genes genetically required PCR employing multiple primers.Results: Successful isolation of sixty-six S. suis isolates occurred primarily from cerebrospinal fluid. The results demonstrated that all isolates exhibited phenotypic resistance to tetracycline, with one isolate demonstrating co-resistance to tetracycline and erythromycin/clindamycin. It is additionally corroborated genetically through the amplification of the tetM gene in every isolate, including those that exhibited concurrent resistance to erythromycin and tetracycline. The intTn gene, which is a member of the conjugate transposon Tn916 family, was amplified and utilized for horizontal media gene transfer on S. suis plasmids carrying the resistance genes ermB and tetM.Conclusion: This research represents the initial investigation into the antibiotic resistance phenotype and genotype of S. suis serotype 2 (SS2) isolated from human subjects in Bali, Indonesia. The findings suggest that the pathogenicity and widespread dissemination of SS2 in the community may have been influenced by the extensive use of tetracycline and the horizontal acquisition of the genetic element Tn916 with tetM.

Abstract

Background: The global COVID-19 pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), experienced a surge in cases with the emergence of the Omicron variant. Despite increasing vaccination coverage, Indonesia witnessed peaks in COVID-19 cases. Variant screening and whole genome sequencing (WGS) play a crucial role in identifying SARS-CoV-2 variants and monitoring their spread.Objective: The objective of this study was to compare variant screening results with WGS data, assess the prevalence of subvariants, and analyze their correlation with demographic and cycle threshold (CT) values.Methods: Between November 7th and 18th, 2022, variant screening and WGS were conducted on samples with CT values below 30. Variant screening utilized the mBioCov-19+ VarScreen assay, while WGS was performed on the Oxford Nanopore Technologies (ONT) platform. Bioinformatics analysis was performed using epi2melabs. Demographic data and CT values were analyzed. Results: Out of 89 subjects, all tested positive for the Omicron variant through variant screening. The variant screening identified two subvariants: Omicron BA.2 (64%) and Omicron B.1.1.529.1 (36%). WGS revealed that the XBB subvariant was the most dominant (52.8%), followed by BQ.1 (22.5%) and BA.5 (13.5%). When VarScreen indicated BA.2, the majority of WGS results showed XBB (82.5%), while for B.1.1.529.1, the majority of WGS results were BQ.1 (59.4%), followed by BA.5 (37.5%). XBB was the most prevalent variant in both females and males, while BQ.1 was more dominant in females (80%). No infections were detected among children aged 1-5 years. All variants had CT values below 24.Conclusion: Variant screening provides accurate and quick results for detecting the Omicron variant in laboratories without WGS capacity. However, it is important to continuously update the screening methodology based on the prevailing circulating variants. During the study period, XBB emerged as the predominant subvariant of the Omicron variant.
