Denture stomatitis is an infection of the mucosa caused by bacteria such as Staphylococcus aureus (S. aureus) accumulating on the denture. Garlic (Allium sativum) contains antibacterial compounds that can be used as an alternative denture cleanser. The purpose of this study was to determine the inhibition effect of immersion in effervescent garlic ethanol extract (Allium sativum) against Staphylococcus aureus growth on heat cured acrylic dental plate. This research was a laboratory experiment in vitro using 40%, 50%, and 60% effervescent garlic ethanol extract. The samples were 12 pieces (n = 12) of heat cured acrylic plates which were divided into 3 treatment groups then incubated in S. aureus suspension for 24 hours and then immersed in an effervescent garlic ethanol extract for 6 hours. Bacterial colonies were counted using a colony counter and the data were analyzed using the One-way ANOVA and LSD Post hoc tests. The statistical analysis showed that the number of S. aureus colonies decreased along with an increased concentration of garlic ethanol extract. The results of the analysis showed that the 60% effervescent garlic ethanol extract had a significantly lower mean number of colonies compared to the 40% and 50% effervescent garlic ethanol extracts (p ≤ 0.05). This research concluded that effervescent garlic ethanol extract prevented the growth of S. aureus on the heat cured acrylic dental plate.

Background: Inflammation is an essential innate immune response aimed at antigen elimination and preventing their spread. Ginger (Zingiber officinale) and bangle (Zingiber cassumunar) rhizomes have been empirically utilized as medicinal components due to their anti-inflammatory potential. However, the combined efficacy of these rhizomes has not been previously explored. Objective: This study aimed to assess the anti-inflammatory activity of a combination of ginger and bangle rhizome extracts. Method: Ginger and bangle rhizomes were individually subjected to extraction through maceration with 96% ethanol, followed by purification with n-hexane. The anti-inflammatory activity was evaluated via motility tests on subjects administered orally with 1% CMC-Na (control), diclofenac sodium (4.5 mg/kg body weight), ginger ethanol extract (200 mg/kg body weight), bangle ethanol extract (400 mg/kg body weight), and a combination of both extracts (100:200 mg/kg body weight). Observations were made over 6 hours, with motility scores subsequently analyzed using ANOVA and the LSD test for statistical significance. Results: Treatments involving ginger extract, bangle extract, and their combination significantly improved motility scores compared to the negative control. Furthermore, these treatments displayed no significant difference in effectiveness compared to the diclofenac sodium group (p > 0.05). Conclusion: The combined ethanol extracts of ginger and bangle rhizomes demonstrate anti-inflammatory activity comparable to diclofenac sodium, as evidenced by motility score evaluations. This suggests their potential as alternative anti-inflammatory agents.

This research explores the impact of Intellectual Capital (IC), Firm Performance, Firm Size, and Intangible Assets on Firm Value, while also assessing differences in IC's effect between firms with varying IC intensity. Additionally, it analyzes changes in Firm Value across the pandemic and post-pandemic periods. The study utilizes a sample of 45 firms included in the LQ45 Index, covering the period from February 1 to July 31, 2024. Data analysis employs multiple linear regression and the Difference-in-Differences (DiD) method using SPSS 26. The findings indicate that while IC, Firm Performance, Firm Size, and Intangible Assets collectively influence Firm Value, only Firm Performance, Firm Size, and Intangible Assets exhibit significant partial effects. Furthermore, no significant difference is found in IC's impact between firms with high and low IC intensity. The study also shows that the pandemic period does not significantly alter Firm Value determinants, suggesting firms have successfully adapted to changing economic conditions.

Plants contain chemical compounds that have medicinal properties. Andrographis paniculata (bitter herb) is commonly used as a traditional medicine, including treating hyperglycemia. A. paniculata was known to contain major compounds, terpenoids, and flavonoids. The phytochemical investigation aimed to isolate and identify chemical compounds from the aerial part of the bitter herb and then evaluate the antihyperglycemic properties. A. paniculata was extracted using 96% ethanol. The extract was partitioned with three organic solvents successively to obtain the chloroform fraction, ethyl acetate fraction, and methanol fraction. Isolation was carried out on the ethyl acetate fraction using column chromatography with a silica stationary phase and an organic solvent mobile phase in various ratios. The isolate in the form of white powder was found in subfraction E8 with the mobile phase chloroform-ethyl acetate (1-2). The structure of the isolated compounds was characterized using spectroscopic methods, including 1D NMR (1H and 13C), 2D NMR (HSQC and HMBC), and LCMS. The isolated compounds were evaluated in vitro with α-amylase and α-glucosidase tests. The results of the data analysis indicated the identification of 14-deoxy-11,12-didehydroandrographolide and 14-deoxyandrographolide as the isolated compounds. The isolated compounds showed α-amylase inhibitory activity with an inhibitory concentration (IC50) of 167.31±4.92 μg/ml and α-glucosidase inhibitory activity with an IC50 of 267.10±6.72 μg/ml. The results of this study indicate that paniculata contains diterpene lactones, which are active in hyperglycemia therapy.

Nagasari (Mesua ferrea L.) has antibacterial activity. Its active compounds are difficult to absorb. Nanoemulsions can enhance the absorption and solubility of these compounds. This study aims to determine the physical stability of a Nagasari extract nanoemulsion, as evaluated by its antibacterial activity. The nanoemulsion was prepared using VCO (1%) as the oil phase, Tween 80 (16%) as the surfactant, and PEG 400 as the cosurfactant, with variations of 1% (FI), 3% (FII), and 5% (FIII). The nanoemulsions were evaluated for their physical properties, solubility, organoleptic properties, pH, emulsion type, transmission percentage, particle size, polydispersity index, zeta potential, and stability. The most effective nanoemulsion was tested against B. subtilis. The results show that FI was stable during freeze-thaw testing. Its pH was 6.2 ± 0.15. FI was found to be an o/w emulsion-type with the following characteristics: transmission (94.23 ± 1.18%), polydispersity index (0.345 ± 0.051), particle size (103.07 nm), and zeta potential (-6.47 ± 2.20 mV). The stability and physical characteristics of the nanoemulsion are affected by variations in the concentration of PEG 400 as a co-surfactant. Antibacterial activity testing of the nanoemulsions resulted in an inhibition zone measurement of 19.15 mm against B. subtilis
