Abstract

A protein can be identified based on each level of its structure. Every protein contains at least primary, secondary and tertiary structures. Only a few proteins have a quaternary structure as well. The primary structure consists of a linear chain of amino acids. One of the electric field-mediated separation methods that is often applied to analyze proteins based on their size is SDS-PAGE electrophoresis. This technique is based on the assumption that after denaturation, the polypeptide chains covered in SDS micelles have comparable surface charge densities, so that the resulting differences in electrical migration are based on their size. SDS-PAGE separates protein molecules based on their particle size and shape. This gel can be made with varying pore sizes which are determined based on the total amount of acrylamide compound added (gel concentration). The gel pore size will become smaller as the gel concentration increases so that only protein molecules that have a small molecular weight can pass through. This measure of the molecular weight of a protein is useful in mapping proteins (protein profiling). The gel staining used is bromophenol blue which functions to color proteins because it binds weakly to proteins. The higher the protein concentration of a sample being electrophoresed, the resulting band will appear clear and thick. However, if the protein concentration of a protein is low, the resulting band will appear thin.

Abstract

Bioinorganic science and the utilization of metal ions in the synthesis and design of new materials have received considerable attention in relation to their use as new biomaterials. One of the important roles of metal ions is to control the characteristics of the resulting biomaterials, namely their biological and chemical properties. To date, main group metal ions and transition metals have been used in the fabrication process of silicate and phosphate-based ceramics. Metal ions are used to modify their chemical composition and structure to overcome the shortcomings of silicate and phosphate-based ceramics. Calcium silicate (CaSiO3, CS) ceramics are biocompatible and bioactive. In this review, we consider the apatite-forming ability and biological properties of ion-doped CS ceramics such as bredigite, akermanite, monticellite, diopside, merwinite, hardystonite, baghdadite and sphene. Overall, according to the studies conducted on CS bioceramics, all of them may be good candidates for bone tissue regeneration

Abstract

Heavy metal pollution such as Cd(II) in the environment is a serious issue that requires effective solutions. This study aims to evaluate the ability of sodium lauryl sulfate surfactant modified activated carbon (SMAC-SLS) in adsorbing Cd(II) from solution. SMAC-SLS synthesis was carried out using wet impregnation method with SLS solution. The adsorption process was tested at various concentrations of Cd(II), and the results were analyzed using Langmuir and Freundlich isotherm models. The results showed that the adsorption of Cd(II) on SMAC-SLS followed the Freundlich isotherm model, with R2 of 0.995, Kf of 1.934 mg/g, and nnn of 5.039, indicating excellent adsorption on the heterogeneous surface. The Langmuir model also gave an R2 of 0.9767 with a maximum adsorption capacity Qmax of 11.83 mg/g and adsorption energy of 22.517 kJ/mol, indicating a possible chemisorption mechanism. Modification of activated carbon with SLS was shown to increase the adsorption capacity as well as the interaction with Cd(II) ions. This suggests that SMAC-SLS has great potential as an adsorbent in the treatment of wastewater containing heavy metals.

Abstract

Vanadium is a metal that has unique characteristics both in the form of free elements, ions, and in the form of complex compounds. In common with other minerals, essential and non-essential, vanadium has a wide range of usual dietary intakes, levels of least observed adverse effects, measures of toxicological exposure, and potential therapeutic effects, with concentration ranges that may be disease specific. This review aims to summarize and evaluate the distribution and interactions between vanadium communities in aquatic, soil, and biological chemical systems. In the aquatic environment, vanadium can be distributed directly by marine microorganisms and marine biota, as well as sediments, which at certain concentrations are very toxic, and several studies have even equated the toxicity of vanadium with other heavy metals such as arsenic, lead, mercury and chromium. In soil, vanadium contamination can originate from parent rocks and anthropogenic activities such as mining, the textile industry, the burning of fossil fuels, and the effects of pesticide use. High concentrations of vanadium can interfere with energy metabolism and matter cycles; inhibits the action of enzymes, protein synthesis, ion transport, and other important physiological processes. However, it is unique because vanadium provides an advantage in plant growth process at low levels. On the other hand, the coordination of vanadium with various types of ligands to make complex compounds significantly enhances the significance of vanadium in various applications such as catalysis in polymerization reactions, and therapeutic agents and drug candidates. Ultimately, although vanadium has demonstrated cytotoxicity in testing as a therapeutic agent, several studies have shown promising opportunities for designing effective and safe vanadium derivates-based antiviral or COVID-19 drug candidates in the future.

Abstract

Breakfast is an essential part of a healthy diet that contributes to physical and mental health. This study aims to analyze the relationship between the habit of skipping breakfast and stress levels among physics students at Universitas Negeri Makassar. The research employs a quantitative method with a cross-sectional design, involving 20 students selected through purposive sampling. Breakfast frequency data were collected using a questionnaire, while stress levels were measured using the Depression Anxiety Stress Scale-21 (DASS-21). The analysis was conducted using Pearson's correlation test.The results show that the majority of students (65%) skipped breakfast 3-4 times a week, while 20% skipped breakfast every day. Pearson's correlation test revealed a significant negative relationship between breakfast skipping frequency and stress levels (r = -0.60, p < 0.05), indicating that the more frequently breakfast is skipped, the higher the stress levels experienced. These findings highlight the importance of breakfast in maintaining emotional stability and reducing stress, particularly among students facing academic pressures.The conclusion of this study emphasizes the need for regular breakfast habits to support students' mental health. Further research is recommended to explore other factors influencing stress and to increase the sample size to strengthen the generalizability of the findings.

Abstract

This study aimed to explore and identify endophytic bacteria from katuk plants (Sauropus androgynus L.) and evaluate their potential as biological control agents. A total of 14 bacterial isolates were successfully obtained from the roots, stems, and leaves of katuk plants. Safety assessments were conducted through hypersensitivity response (HR) and hemolysis (HL) tests. The HR test on tobacco plants indicated that all isolates were non-pathogenic, as no necrotic symptoms were observed. However, the hemolysis test revealed two isolates capable of forming α-hemolysis zones on blood agar, suggesting potential risks to mammals. Antibacterial activity against the plant pathogen Ralstonia solanacearum was evaluated using spot inoculation methods. The results showed that none of the isolates were able to inhibit the growth of R. solanacearum. Although the isolates may produce antibacterial compounds, the amounts are likely insufficient or involve unidentified active compounds. Further studies are needed to fully characterize these isolates and explore their potential applications in sustainable agriculture.

Abstract

Clean and healthy living behavior is an action to maintain personal hygiene, well-being, physical and psychological to improve health. Marginal children are identified as a community that receives less attention regarding healthy living behavior, especially personal hygiene. This disrupts their daily lives, especially the need for personal hygiene. This study aims to determine the behavior of knowledge about personal hygiene, body image, social support, and the availability of facilities at home. This study uses a qualitative approach. Determination of informants using purposive sampling techniques. Data collection through in-depth interviews using interview guides. The survey results show that there are some marginal children who already know about it but have not fully understood it. The body image of marginal children that they believe in the clothes they wear every day, want to look attractive. The emotional role of parents towards marginal children who support children to always maintain personal hygiene. In addition, supporting facilities in the implementation of good personal hygiene are still not available in children's houses.
