Abstract

Nasopharyngeal carcinoma (NPC) is one of the most common malignancies in the ENT department, with a high incidence in Southeast Asia. One of the major risk factors for NPC is formaldehyde exposure, which induces oxidative stress, chronic inflammation, and disruption of growth factors such as Epidermal Growth Factor (EGF). This study aims to analyze changes in EGF levels in Rattus norvegicus exposed to 40 ppm formaldehyde for one month to better understand the molecular mechanisms contributing to nasopharyngeal carcinogenesis. This experimental study measured EGF levels using the Enzyme-Linked Immunosorbent Assay (ELISA) method. Data were analyzed using the Kolmogorov-Smirnov normality test and a Paired T-Test to assess changes in EGF levels before and after treatment. The analysis showed a tendency for increased EGF levels after formaldehyde exposure; however, the difference was not statistically significant (p = 0.355). This suggests that one-month exposure to formaldehyde does not directly affect EGF expression in the tested tissue. This study found that 40 ppm formaldehyde exposure for one month did not significantly alter EGF levels. However, the observed trend in certain groups suggests that the effect of formaldehyde on EGF levels may be dose- and duration-dependent. Further studies with longer exposure durations and higher concentrations are needed to explore the link between formaldehyde exposure and nasopharyngeal carcinogenesis.

Abstract

A worldwide issue that has not been adequately addressed is stunting. One of the many causes of stunting is inadequate nutrition. There are two types of nutrients: macronutrients and micronutrients. Iron is one of the micronutrients that the body actually needs. Lack of iron consumption is one of the risk factors for stunting, according to a number of earlier research. The aim of this study was to ascertain the correlation between the occurrence of stunting in toddlers aged 24 to 59 months in the Nipah Health Center work area and iron (Fe) intake. This study employs a case control methodology and combines quantitative and analytical observational methods. Ultimately, we discovered that 30 individuals, or 78.95% of the 38 research participants, had iron intakes below 77%. The statistical test of iron consumption and stunting incidence showed that p = 0.042. This indicates that the incidence of stunting and iron intake are related.

Abstract

Curcuma sumatrana or Koenih Rimbo, is an endemic plant of West Sumatra that is threatened with extinction due to deforestation, climate change, and human activities. This study aims to understand the ecology of C. sumatrana to support effective conservation efforts. The study was conducted in seven potential locations in West Sumatra using exploration methods and analysis of environmental factors, such as altitude, temperature, humidity, soil pH, and canopy cover. The results showed that this species was only found in three locations, namely Lubuk Kilangan, Koto Malintang, and Koto Pulai, with the highest population in Koto Malintang. Environmental factors such as altitude, canopy cover, and air humidity were shown to support optimal growth of this species. Canonical Correspondence Analysis (CCA) identified a close relationship between environmental factors and morphological parameters, including plant height, number of branches, and leaf size. This study emphasizes the importance of natural habitat conservation and further research on the ecology of this species to prevent its extinction.

Abstract

Traditional land use is a method of land use that has been carried out for generations by the community. Land management activities carried out from generation to generation, with the same pattern from year to year, such as land use which is often called Tebas Bakar and Mamar. Both land uses with different management methods can indicate changes in soil conditions as a medium for plant growth in their physical properties. The purpose of this study was to determine soil permeability in traditional land cultivation activities in Niukbaun Village, West Amarasi, NTT. Field and laboratory research was carried out in August-October 2024. The research location was in Niukbaun Village, West Amarasi District, with the traditional Tebas Bakar and Mamar management systems. Research Methods Data collection includes primary data, secondary data, Permeability observations were carried out in the field using a permeameter. The results obtained: Soil permeability on mamar land is better than slash and burn land. Each type of traditional land use differs according to its management method. So that texture, organic material and land use processing have an influence on the size of the soil permeability.

Abstract

Depression is a common mental health disorder in the elderly, often coexisting with chronic conditions like hypertension. This study examines the relationship between depression and hypertension stage 2 among elderly individuals at Puskesmas Karang Taliwang, considering age and gender. A cross-sectional study of 30 elderly patients used a validated questionnaire to assess depressive symptoms. Results showed a significant association between age (≥60 years) and depression, while gender had no statistical correlation. Hypertension stage 2 was also significantly linked to depression, though with a small effect size. These findings highlight the need for integrated healthcare strategies addressing both mental and cardiovascular health in the elderly. Further research is needed to explore underlying mechanisms and potential interventions.

Abstract

The anti-fibrotic, anti-inflammatory, and antimicrobial qualities of moringa leaf extracts, which are high in saponins, flavonoids, steroids, and phenols, can aid in tissue regeneration and wound healing. The aim of this study was to prepare and formulate a transdermal patch of Moringa oleifera Lam. leaf extract with hydroxypropyl methylcellulose (HPMC) and polyvinyl pyrrolidone (PVP) as the polymers. The study was aimed at investigating the effect of various concentrations of the extract (20%, 40%, and 80%) on the physical properties of the patch, including organoleptic properties, weight uniformity, thickness, folding endurance, pH, and water absorption. Extract was made by maceration with 96% ethanol, and patches were cast by the solvent casting method. Results showed that all formulations met the required pH range (6.62–6.68), folding endurance (>300 folds), and thickness (<1 mm). However, weight uniformity and moisture absorption exceeded desired optimum values and ranged between 17% to 23%. The 20% concentration of extract exhibited the maximum physical stability. This study highlights the potential of Moringa oleifera leaf extract in transdermal patch preparations, although it needs to be optimized to improve weight consistency and water absorption.

Abstract

One of the bacterial pathogens that is often a serious concern in freshwater fish farming is Edwardsiella ictaluri, a causative agent of Enteric septicemia of catfish (ESC). Edwardsiella ictaluri which generally attacks catfish groups such as lele, patin, and sidat, but can also attack other species, such as tilapia. Therefore, alternative efforts are needed that are more environmentally friendly, safe for consumers, and do not trigger bacterial resistance. One of the plants that has the potential as a source of natural antibacterials is henna leaves (Lawsonia inermis L.). The purpose of this study was to determine the potential of henna leaf extract (Lawsonia inermis L.) as an antibacterial against Edwardsiella ictaluri and to determine the concentration of henna leaf extract (Lawsonia inermis L.) that is most effective in inhibiting the growth of Edwardsiella ictaluri bacteria. The method used in this study was disc diffusion. Analysis was conducted by testing the data for normality, homogeneity, kruskall wallis test and continued with the Dunn test using SPSS software version 26. The concentration of henna leaf extract of 3%, 6%, 12%, 24% and 48% is known to be able to inhibit the growth of Edwardsiella ictaluri bacteria with an average inhibition zone of 10.45 mm, 11.73 mm, 13.25 mm, 14.51 mm and 16.85 mm respectively. Henna leaf extract has the ability to inhibit the growth of Edwardsiella ictaluri bacteria with a strong category. A concentration of 48% is an effective concentration in inhibiting the growth of Edwardsiella ictaluri.

Abstract

One alternative treatment for diabetes mellitus is herbal therapy. One example of herbal therapy that can be used to treat diabetes mellitus is cherry. Cherry (Muntingia calabura L.) is a plant that is widespread in Indonesia, including NTB. In West Nusa Tenggara, cherry plants are very abundant and can often be found on roadsides and in house yards. One of the compounds contained in cherry leaves which has antidiabetic and antioxidant activity is flavonoids. The aim of this research was to determine the potential of ethanol flavonoid extract to reduce blood sugar levels in mice induced by alloxan. The manufacture of cherry leaf ethanol extract was carried out using the sonication method, with the testing process including qualitative tests, quantitative tests, evaluation of cherry leaf ethanol extract suspension preparations, and measurement of fasting blood sugar. The results of blood sugar measurements showed that administering a dose of 300 mg/kg showed the best results which were almost the same as the positive control (metformin).

Abstract

A disorder known as anemia occurs when the body's hemoglobin level falls. Oxygen is transported throughout the body by hemoglobin. Because puberty alters the body's nutritional and physiological requirements, teenage females are among the groups most at risk for anemia. If adolescent girls' anemia is not addressed with regular Fe pill use, it can impair their capacity to learn and result in pregnancy. Adolescent girls' consumption of Fe pills is influenced by a number of factors, including distribution of the tablets, school assistance, attitude, and knowledge. This study aims to determine the factors that influence the consumption of Fe tablets in adolescent girls. The type of research conducted is an analytical survey study with a cross-sectional approach and using chi-square data analysis with a sample size of 68 respondents. The results of the study showed that the variable level of knowledge was dominated by the less category (50%) and had a p-value of 0.000, the attitude variable was dominated by a positive attitude (54.4%) and had a p-value of 0.061, the school support variable was dominated by the less supportive category (54.4%) and had a p-value of 0.041, the overall distribution variable of Fe tablets received tablets once a week (100%) and the p-value could not be assessed (NA).
