Abstract

Liver cirrhosis is a pathological liver disease characterized by the formation of fibrous tissue and regenerative nodules in liver cells. The potential for hepatotoxicity due to the use of hepatotoxic drugs leads to worsening of the liver disease suffered by these patients. This study aims to assess the impact of using potentially hepatotoxic drugs on patients' clinical outcomes. This study was an observational study with a cross-sectional design. Data were collected retrospectively through the medical records of patients with liver cirrhosis hospitalized in 2021. The clinical outcomes studied were SGOT, SGPT, albumin, total bilirubin and length of hospitalization. The results obtained were tested using the Kruskal-Wallis statistical test. A total of 62 patients with liver cirrhosis met the inclusion criteria as the study sample. The number of potentially hepatotoxic drug prescriptions received by patients based on Likelihood scores with categories A, B, C, D and E was 368 drugs out of 776 total drug prescriptions (47.4%). The most commonly prescribed potentially hepatotoxic drugs were paracetamol, ceftriaxon, and levofloxacin. It can be concluded that potentially hepatotoxic drugs are still prescribed to patients with liver cirrhosis. Age, gender, child pugh-score, number of drugs, and number of potentially hepatotoxic drugs had no significant effect (p>0.1) on SGOT, SGPT, albumin and total bilirubin. However, patients who received more drugs would have a higher.

Abstract

This study aims to find the presence of microplastics in Shellfish through the literature review method of several studies conducted. The increase in plastic pollution in water systems since the 1950s has become a significant problem worldwide due to the slow decomposition rate. Microplastics, mainly primary and secondary, can accumulate in marine organisms such as Shellfish and enter the food chain, which is a concern for humans. Shellfish, especially M. galloprovincialis, can be used as bioindicators and bioremediation tools to tackle microplastic pollution. Microplastics are a severe problem in the world's oceans, especially in marginal and densely populated coastal areas. Marine organisms like Shellfish contain microplastics, which can cause physical damage and disrupt the immune system. Mytilus edulis clams and Crassostrea gigas oysters are the most consumed species with significant microplastic content. Research has also shown the presence of microplastics in Mytilus chilensis in the Gulf of Ushuaia, South America, with fibers and fragments being the most common types. Microplastics are also found in wild mussels in Tunisia, with the estimated annual dietary intake of microplastics by Tunisians through wild mussel consumption amounting to 4.2 particles per capita per year. Mussels of the genus Mytilus were proposed as guardian organisms to monitor microplastic pollution.

Abstract

Activated carbon from corn stalks (Zea mays L.) has been successfully synthesized by the dehydration method and used as a supercapacitor electrode. Corn stalk powder was dehydrated with 1 MH2SO4 and activated with 5 M NaOH at a carbon and activator mass ratio of 1:4 with a heating temperature of 800°C and an N2 gas heating rate of 10°C/minute for 1 hour. SEM characterization results show that heterogeneous pores have formed on the surface of corn stalk-activated carbon. EDX results showed a carbon percentage of 54.82%; this data is supported by FTIR results, which show several functional groups containing C and O atoms on the surface of activated carbon. Based on desorption adsorption isotherm analysis, the activated carbon shows H4 type with a specific surface area of 117.973m2/g, average pore diameter of 1.730 nm and total pore volume of 0.1021 cm3/g. Measurement of the electrochemical properties of corn stalk activated carbon with a three-electrode system and 3 M KOH electrolyte showed a specific capacitance value of 133.9 F/g, power density 225.2 W/kg and energy density 0.863 Wh/kg. The synthesis of activated carbon through the dehydration method offers advantages in terms of simplicity in preparation, low cost, shorter synthesis time and being environmentally friendly.

Abstract

The Moringa plant, a tropical species, exhibits prolific growth and is abundantly present in Indonesia and other tropical regions worldwide. An extended lifespan, continuous flowering, and a high tolerance for elevated temperatures characterize it. Utilizing its components, including leaves, bark, seeds, and roots, this multifaceted plant is renowned for its therapeutic properties. The plant's antioxidants and various nutrients, including vitamins and minerals (iron, magnesium, vitamin B6, vitamin B2, vitamin C, and vitamin A), have led to studies on the plant's potential health benefits. In order to develop the local economy in Ulakan village, Padang Pariaman Regency, Moringa plants were processed by using the plant leaves to manufacture herbal tea, which can then be sold. This community service program was significant given the widespread presence and ease of cultivation of Moringa plants within the local region. The program involved the planning and selection of the activity site, the implementation of training sessions, and the assessment of the program's outcomes. The result of this community engagement initiative was the demonstrated interest of many participants in producing Moringa leaf tea.

Abstract

Remazol Yellow FG is one of the dyes that are often used in the textile industry because it is accessible and reasonably priced. The non-biodegradable dyes produce waste and inhibit sunlight from passing through the water. In this study, we performed Fourier Transform Infrared (FTIR) to characterise the activated carbon of rice husk and TiO2/activated carbon rice husk (TiO2/AC) using Diffuse Reflectance Spectroscopy UV-Vis (DRS UV-Vis). Remazol Yellow FG was degraded by using sonolysis and photolysis under UV ray (λ = 254 and 365 nm) and visible ray. We performed the experiments using a variety of variables which consist of catalyst dosage (10–50 mg), contact time (1–6 hours), catalyst type (AC, TiO2 and TiO2/AC), lamp type (365 nm, 254 nm and visible lamp) and initial Remazol Yellow FG concentration (10–30 mg/L) to determine the degradation percentage. We found that the addition of TiO2/AC catalyst increased the degradation percentage of Remazol Yellow FG from 6,86% to 52,62% using sonolysis and 8,34% to 95,02% using photolysis. Hence, we concluded that TiO2/AC catalyst from rice husk could be an effective catalyst for the Remazol Yellow FG degradation.

Abstract

Sustainable aquaculture requires environments free from microplastic contamination. However, microplastics are now commonly found in aquatic systems, including fish farms, where they can accumulate in organisms and enter the food chain. This study evaluates the effectiveness of biofloc technology in reducing microplastic levels in water and Nile tilapia (Oreochromis niloticus), using ecological risk indices: Pollution Hazard Index (PHI), Pollution Load Index (PLI), and Potential Ecological Risk Index (PERI). The experiment lasted 50 days with four treatments, including polyethylene (PE) and polyethylene terephthalate (PET) exposure. Microplastic concentrations ranged from 0.12 to 0.33 particles/L, with highest accumulation in the fish esophagus (39.2 ± 6.87 particles/g). Identified polymers included PE, PVC, and PA. Risk indices showed PHI = 166.69, PLI = 1.01–1.66, and PERI = 21.49, indicating medium to high ecological risks. Results show that biofloc effectively reduces microplastic levels, making it a promising solution for sustainable aquaculture. The study highlights the need for better plastic waste management policies and stricter regulation of PVC and PET near farming areas.
