Abstract

Atherosclerosis is triggered by cholesterol accumulation in endothelial layers that induces the production of inflammatory cytokines, including TNF-α, IL-6, and IL-10. This condition disrupts microRNA homeostasis like miR-29b-3p, generally maintaining artery health. Steamed tomatoes contain higher antioxidant properties than raw, which might be better against atherosclerosis. However, its influence on inflammation and miR-29b-3p balance remains unclear. This study aims to elucidate the effect of steamed tomatoes on the TNF-α, IL-6, and IL-10 levels and miR-29b-3p expression under atherosclerosis conditions. Sprague Dawley male rats were equally divided into K1 group of healthy rats given a placebo; K2 group was atherosclerosis rats induced with 2 m of cholesterin/ 200 g/KgBW per day, then K3 and K4 groups were atherosclerosis rats supplemented with 20 mg/ 200 g/KgBW per day of atorvastatin and 16 mg/ 200 g/KgBW per day of steamed-tomato extract for 60 days. Steamed tomato decreases cytokine level in the K4 group and significantly differs from all groups (p < 0.050). This study showed that increased proinflammatory cytokine, including TNF-α and IL-6, is hypothetically involved in plaque formation and lamina layer destruction in endothelial. Steamed tomato supplementation also significantly increases miR-29b-3p expression to 0.98 ± 0.33 log10 fold change higher than K2 and K3 (p = 0.000). This study demonstrated the potential of steamed tomatoes to improve dyslipidemia, atherosclerosis-related inflammation, and miRNA homeostasis. This research provides additional knowledge regarding determining the expression of miR-29b-3p, which has the potential to be developed as a diagnostic or therapeutic target.

Abstract

This study aims to determine the effect of tempeh yeast inoculum on the color, odor, and yield in the manufacture of Virgin Coconut Oil (VCO) from Cocos nucifera viridis. This research was conducted in November 2020 in Brebes, Magelang, and Lampung. This research employed the descriptive quantitative method. The population of this experiment was coconut fruit found in Lampung, Brebes, and Magelang. The sample used was green coconut (Cocos nucifera viridis) found in Lampung, Brebes, and Magelang. The working procedure of this research consisted of fermenting the sample and observing the oil produced by Virgin Coconut Oil. This research's data collection techniques were observation, documentation, and products calculation. Based on the observations, the researchers found the highest yield in the experiment of 80 ml cream with an inoculum of 8 grams (30.4%), followed by a volume of 80 ml of cream with a 6-gram inoculum (28.4%). The smallest yield was formed at a volume of 80 ml cream with inoculum 4 grams (14.6%). The VCO obtained in this research had a distinctive aroma of coconut oil and was clear in color. Therefore, the amount of tempeh yeast inoculum affects the color, odor, and yield in the manufacture of Virgin Coconut Oil (VCO) from Cocos nucifera viridis.
