Abstract

Black rice is a food crop with black pigments, which helps reduce the risk of various diseases and improve health. One way to improve food quality and avoid food contaminants is by irradiating. This study evaluated the phytochemical profile, antioxidant activity, and anticancer activity of irradiated black rice bran extract (IBRBE) in vitro and in silico. Black rice was irradiated with a Gamma cell 220 type irradiator at a 7.5 kGy/hour dose rate. Extraction of irradiated black rice bran was carried out using the maceration method. Phenolic and flavonoid components were quantified using the Folin–Ciocalteau and AlCl3 methods, respectively. Phytochemical compounds were identified by liquid chromatography-high-resolution mass spectrometry (LC HRMS). The antioxidant activity of IBRBE was carried out against 2,2-diphenyl-1picrylhydazyl (DPPH). The cytotoxic activity of IBRBE against WiDr cells (colorectal cancer) and Vero (nonhuman cell lines) used the MT test method. Prediction of the inhibitory mechanism of compounds in the extract against target proteins EGFR and GPX7 was carried out in silico. Total phenolics and flavonoids were 2.57 ± 0.28 mg GAE/g and 19.12 ± 0.18 μg QE/ml, respectively. Twenty-four types of active compounds were obtained in IBRBE. The results of antioxidant activity obtained an IC50 value of 1198.45 ± 92.86 μg/ml. IC50 in WiDr cells and Vero cells were obtained at 36.08 ± 11.71 μg/ml and 570.58 ± 130.25 μg/ml, respectively. In silico results, the compound 4 Dodecylbenzene sulfonic acid has the highest binding affinity to the EGFR protein, with a value of -5.9. Meanwhile, the Monoolein compound has the highest binding affinity to the GPX7 protein, with a value of -5.4.

Abstract

Anemia in pregnant women is a condition of low hemoglobin levels in pregnant women which is a common health problem and can affect both the mother and the fetus. One potential non-pharmacological method to overcome anemia is giving date infused water. Dates are rich in iron, vitamin B complex, and vitamin C which support the formation of hemoglobin and iron absorption. This study aims to analyze the effect of giving date infused water on hemoglobin levels in pregnant women. This study used a quasi-experimental design with a one-group pretest-posttest approach. The study population was all pregnant women in the third trimester with anemia at TPMB Mintarsih, S.SiT., Bd in the month of 33 people. The sampling technique was carried out using the total sampling technique. The results of the study showed that giving date palm infused water significantly increased hemoglobin levels in pregnant women with anemia in the third trimester. The Paired Samples Test statistical test produced a p value = 0.003 (p < 0.05), which indicates a significant effect of giving date palm infused water on increasing hemoglobin levels. This study recommends date infused water as a non-pharmacological intervention that can be used to support the health of pregnant women.

Abstract

ABSTRACT Background: People with disabilities, especially the blind, are members of society who have limited vision. Therefore, they require specific methods to learn certain skills to earn a living. One such skill suitable for the blind is massage therapy, which can be learned without relying on sight, but relying on the sense of touch. Purpose: This paper aims to describe the experience of training blind people to perform a special massage treatment called Tuina Chuzhen. Methods: The experience of training blind people to perform Tuina Chuzhen massage is described chronologically and systematically from facts and primary data collected during six training sessions at the Daya Dharma Institute of the Archdiocese of Jakarta, with support from traditional Chinese medicine experts from the Nalanda Institute. Main Results: The Tuina Chuzhen massage training for 20 blind people went smoothly during six sessions over a period of one month. The training participants successfully mastered the Tuina Chuzhen method using the provided short wooden rods. Mastery of these skills was evident in the participants' recognition and their ability to pass the competency test conducted by the Nalanda Institute's assessment team after the training. Conclusion: Tuina Chuzhen massage training can bring tangible benefits to the visually impaired. Keywords: Massage, tuina Chuzhen, disability, visual impairment.
