Abstract

L-Citrulline shows potential activity as a supplement to prevent myocardial infarction through vasodilative and possible antioxidative effects but may be deleterious by causing nitrosative stress. This study determined the potentially deleterious effects of L-citrulline supplementation in isoproterenol-induced myocardial infarction with a focus on nitrosative stress. L-Citrulline supplementation was given orally at dosages of 300 or 600mg/kg body weight daily for 6 days. Myocardial infarction was induced in Wistar rats via subcutaneous injection of isoproterenol (85 mg/kg body weight (BW)) on day 4 and 5. Blood pressure was measured at the end of the study (day 6) and rats were sacrificed to collect heart tissue samples for a histopathological evaluation. The histopathological evaluation was done using hematoxylin and eosin staining for the myocardial damage evaluation and immunohistochemical (IHC) staining of arginase-2, inducible nitric oxide synthase (iNOS), and 3-nitrotyrosine to evaluate nitrosative stress. L-Citrulline supplementation failed to show a significant protective effect on blood pressure and exacerbated the decrease of diastolic blood pressure. Both low and high dose L-citrulline supplementation had a significant protective effect on myocardial damage compared to the isoproterenol group (p<0.01). L-Citrulline also caused increased nitrosative stress as shown by increased expression of arginase-2 and 3-nitrotyrosine on IHC staining but tended to show an ameliorative effect on iNOS expression. A significant increase in arginase-2 expression was detected between the high dose group and the other groups (p<0.01 vs. normal and isoproterenol groups; p<0.05 vs. low dose group). L-Citrulline supplementation increased 3-nitrotyrosine expression in a dose-dependent manner, which was significantly different compared to the normal group (low dose: p<0.013; high dose: p<0.003). L-Citrulline increased the production of nitrosative stress but resulted in less myocardial damage through its other effects.

Abstract

The functional ability of the brain will decline progressively during aging which usually involves changes in plasticity. BDNF is one of the neurotrophins that regulates plasticity via TrkB receptors. So the potential of Moringa oleifera leaf and seed oil extracts was identified as neuroprotective on the interaction of TrkB receptors with molecular docking. The active compounds of Moringa oleifera leaf extract and seed oil were obtained from literature studies. Drug-likeness and ADMETox analysis were carried out using the SwissAdme and the AdmetSAR webserver. The molecular docking was carried out using the Pyrx Vina application and visualization is done using the Discovery Studio Biovia application. The docking results showed the best compounds namely luteolin, stigmasterol, and moringin as a marker compound and showed the interaction of hydrogen and hydrophobic bonds at the active site of the prediction results. So it can be concluded that compounds in the leaves and seed oil of Moringa oleifera, namely luteolin, stigmasterol, and moringin are predicted as ingredients that can activate TrkB receptors in the aging process.

Abstract

Hypertensive nephropathy (HN) is a common complication of chronic hypertension that leads to kidney damage. This study aimed to identify potential biomarkers and key pathways associated with HN using bioinformatics tools. Gene data related to HN were retrieved from GeneCards and the Comparative Toxicogenomics Database (CTD), resulting in 89 genes from GeneCards and 10,898 genes from CTD. A Venn diagram revealed 58 overlapping genes, which were then analyzed using Protein-Protein Interaction (PPI) networks and the CytoHubba plugin in Cytoscape. The Maximal Clique Centrality (MCC) algorithm identified 10 hub genes, including ACE, AGT, ACE2, AGTR1, and AGTR2, integral to the renin- angiotensin-aldosterone system (RAAS). Functional enrichment analysis using Gene Ontology (GO) and KEGG pathways revealed that the most significant biological process was regulating systemic arterial blood pressure by the Renin-Angiotensin system, with the renin-angiotensin system pathway being the most highly enriched. Further visualization using ShinyGo highlighted the involvement of key genes in the RAAS pathway. These findings provide valuable insights into the molecular mechanisms underlying HN and suggest that bioinformatics approaches can aid in the identification of specific biomarkers for early diagnosis, non-invasive monitoring, and targeted treatments for HN in the future.

Abstract

Hypertension is Sepsis is a systemic inflammatory response syndrome caused by infection. Globally, the incidence of sepsis has increased with increasing mortality. Antibiotics used appropriately are considered to reduce mortality in sepsis. Destination of this study was to evaluate the use of antibiotics in septic patients in room care Gatot Army Hospital ICU Soebroto by qualitative with method old nor quantitative with method ATC / DDD. Method : Study this is study descriptive analytic and data collection is done retrospectively. The study was conducted by looking at the medical records of patients receiving antibiotic therapy who were treated at the hospital room Gatot Army Hospital ICU Soebroto period January 2020- December 2021. Results : Between 97 patient, 63 patient of them are male ( 64.9 %) and 34 patient Others are female ( 35.0 %). The highest age range is in the age of > 65 as many years ( 43.3 %). d result From the evaluation of the quality of antibiotics, it was found that the use of antibiotics was appropriate k (79%), possible appropriate (20.4%) and no exactly as much (0.52%). while the quantity of antibiotic use is obtained in total DDD/100 patient day take care as much 326.52 with antibiotics the most is usage meropenem 97.75 DDD/100 patient-day take care.
