Abstract

Approximately 70-75% of reproductive women have experienced vulvovaginal candidiasis at least once, and 40-45% will have recurrences. Candida albicans is the most etiology of vulvovaginal candidiasis and is able to form a biofilm that can lead to antifungal resistances and recurrences. One of the natural products that have an anti biofilm effect is propolis. This study expected that propolis from Lawang can be one of the anti-biofilm agent candidates for antifungal resistant cases. This study aimed to know the anti-biofilm effect of propolis ethanol extract on cell adhesion index, morphology, and viability of Candida albicans cell on biofilm formation. The adhesion index was counted on 100 epithelial cells under light microscopy (1000x). Morphology was seen using light microscopy (400x). Cell viability was examined by CFU assay. At 12.5% concentration of propolis ethanol extract, adhesion index decreased (p=0,000), and hyphal growth was inhibited. Colony growth decreased at 2.5% concentration and was not seen at 10% concentration of propolis ethanol extract (p=0,000). These results indicated that propolis ethanol extract could decrease adhesion index, failed the Candida albicans morphology transition from yeast to hyphal, and decreased Candida albicans cell viability on biofilm formation. Propolis ethanol extract is likely to be one of the alternatives to recurrent vulvovaginal candidiasis treatment, especially caused by Candida albicans biofilm formation.

Abstract

Stunting is a chronic growth disorder caused by prolonged nutritional deficiencies and environmental stress, resulting in reduced height for age. Mitochondrial dysfunction and oxidative stress are increasingly recognized as key contributors to impaired growth and cardiometabolic instability during early development. This study investigated the potential protective effects of Virgin Coconut Oil (VCO) and folic acid on insulin signaling and cardiac finction in a rotenone induced stunted zebrafish larval model. A laboratory experimental study with a true experimental post test only controlled group design was conducted among 30 Zebrafish (Danio rerio) for Irs gene expression at 9 day post fertilization (dpf) as samples per tube, heart rate was measured at 3, 6, and 9 dpf. The total group treatment was five with inclusion and exclusion criterias, negative control (NC), positive control exposed to rotenone (12.5 ppb), VCO treatment (6.25%), folic acid treatment (70 µM), and a combination of VCO and folic acid. Variables assessed in this study included heart rate and insulin receptor substrate (Irs) were evaluated using real time polymerase chain reaction (RT-qPCR) analysis. Data were analyzed using SPSS version 27 for windows. Rotenone significantly reduced Irs expression compared with negative control (0.272 ± 0.128 vc 1.014 ± 0.187; p<0.001). Treatment with VCO (0.678 ± 0.250), folic acid (0.676 ± 0.191), and their combination (0.695 ±  0.231) increased Irs expression relative to the rotenone group (p<0.05), although no significant differences were observed among the treatment groups. Rotenone also elevated heart rate at 9 dpf (236.9 ± 19.2 bpm) compared with the negative control (163.7 ± 10.1 bpm), whereas treatment groups showed improved cardiac parameters. These findings highlight the potential of nutritional interventions targeting mitochondrial oxidative stress to support recovery of insulin signaling and improve metabolic stability in stunting related conditions.
