Nadiya Syafiah Mufida — 2025-07-20

Soy milk, an extract from soybeans, significantly contributes to human nutritional needs, particularly as a source of plant-based protein. The protein quality in soy milk is highly influenced by processing parameters, including soybean soaking duration and grinding temperature. This study aimed to determine the optimum combination of soaking time and grinding temperature to maximize soy milk's protein content. The effects of these two factors were evaluated using Response Surface Methodology (RSM) with a Central Composite Design (CCD). Experiments were conducted for 13 experimental combinations, replicated three times. Protein content was determined by the Lowry method, while pH measurements were also performed to monitor quality. Grinding temperatures ranged from 25°C to 80°C and soaking times varied from 6 to 12 hours, using Grobogan soybean variety as the main raw material. Other parameters such as soybean quantity, water volume, soaking temperature, and boiling and grinding times were set as controlled variables. Optimization results using Design-Expert software indicated that the optimum formulation was achieved at a grinding temperature of 61°C and a soaking time of 9 hours 46 minutes. Under these optimum conditions, the resulting soy milk exhibited a protein content of 3.1% (w/w) and a pH of 7.02, both meeting established soy milk quality standards.

The heart is an organ significantly impacted by diabetes mellitus problems, as elevated free radical generation and oxidative stress from hyperglycemia activate the apoptosis and necrosis pathways in cardiac myocytes. This study aimed to ascertain the histological characteristics of the cardiac tissue in rats subjected to hyperglycemia following the administration of ethanol extract from nutmeg fruit flesh (Myristica fragrans Houtt). This study employed rice as a diabetes inducer in 25 rats, categorized into 5 treatment groups: group 1 received Na-CMC, group 2 received metformin, group 3 received a dosage of 100 mg/KgBW, group 4 received a dosage of 200 mg/KgBW, and group 5 received a dosage of 300 mg/KgBW. The detected data included alterations in body weight, blood glucose levels, organ mass, and cardiac histology. The data were evaluated employing the One-Way ANOVA test at a 95% confidence level (p<0.05). The findings indicated that all groups treated with nutmeg fruit flesh ethanol extract exhibited a substantial enhancement in the histopathology of rat hearts compared to the negative control group 0,03 (p<0.05). The administration of nutmeg fruit flesh extract can ameliorate histopathological damage to the hearts of hyperglycemic rats at doses of 100 mg/KgBW, 200 mg/KgBW, and 300 mg/KgBW, indicating that nutmeg fruit flesh may serve as a cardioprotective drug in diabetic subjects.

Folic Acid Supplementation in First-Trimester Pregnant Women for Preeclampsia Prevention: A Retrospective Cohort Study

Andi Maulana Kamri — 2025-07-22

Preeclampsia is a disorder characterized by hypertension and proteinuria that manifests during gestation. Various vitamins can influence food consumption during pregnancy. Folic acid supplementation is known to reduce preeclampsia risk, yet adherence remains low among pregnant women. The objective of the research is to identify risk variables and dosage efficacy associated with folic acid utilization. This study employs an retrospective cohort study and utilizes retrospective data collection. Data was gathered from Cahaya Ibu Pharmacy Store in Makassar, encompassing a total of 164 patients. A chi-square statistical study indicated a substantial risk association between pregnant women and the onset of hypertension in comparison to nonpregnant individuals, with a p-value of 0.001. Pregnant women had twice the risk, as shown by an odds ratio of 1.9. The study of Fisher's test data indicates a correlation between patient age and hypertension condition. The findings indicate no substantial correlation between the two variables, with a p-value of 0.523. The findings indicate a substantial correlation between the mitigation of raised blood pressure risk and the consumption of folic acid. The early use of folic acid during pregnancy planning significantly diminishes the likelihood of preeclampsia. Risk factors for preeclampsia include insufficient folic acid consumption, the duration of folic acid supplementation, and the pregnancy status of individuals with a disease risk of up to 98%. Less at age 30 years old, the consumption of folic acid may reduce the risk.
