Abstract

Post-partum depression (PPD) is a depressive episode that lasts up to four weeks after childbirth. Depression in mothers can affect various aspects of life, such as work, family, spouse, and children. There is a high incidence of suicidal thoughts in mothers who experience PPD, contributing significantly to maternal mortality rate. Understanding more about DPP is the main focus of this paper. This article utilizes a literature review method that collects sources from PubMed, Google Scholar, and Science Direct. This literature review explores various aspects of PPD including epidemiology, pathophysiology, clinical manifestations, diagnosis and treatment. Various physiological changes in the mother's body before and after childbirth increases the mother's vulnerabilities to mood disorders. The mechanisms of PPD involve various pathways, both external and internal. Internal factors include a decrease in certain hormones and neurotransmitters, a history of mental health disorders, and genetic predispositions. External factors include anxiety, external pressures, and lack of social support. The diagnosis of PPD can be established using the DSM-V and ICD-10 criteria. Treatment for PPD can involve both non-pharmacological and pharmacological therapies. PPD is a serious mental condition that causes various negative effects for both the mother and her family. The dysregulation of neuro-hormonal pathways is the primary mechanism in the pathogenesis of PPD. Effective diagnosis and appropriate treatment approaches are crucial in the management of PPD.

Abstract

Reye's syndrome is a rare disease that has the potential to damage several organs, particularly the brain and liver. The exact cause remains unknown, but several cases suggest a link to viral and bacterial infections, especially Influenza and Varicella. The clinical symptoms of Reye's syndrome include altered consciousness, fever, seizures, lethargy, vomiting, tachycardia, respiratory rhythm disturbances, changes in muscle tone, altered reflexes, and reduced urine production. This study aims to understand the clinical characteristics and evaluate the effectiveness of management in patients with Reye's syndrome through a literature review. The findings indicate that Reye's syndrome frequently affects children following viral infections, with initial symptoms of vomiting and altered consciousness progressing to coma. Laboratory tests reveal elevated liver enzymes and hypoglycemia, while prompt management, such as stabilizing vital functions and managing intracranial pressure, can improve prognosis. In conclusion, Reye's syndrome requires rapid intervention to prevent further organ damage, and education on the risks of aspirin use in children with viral infections, along with early intervention, is crucial to reducing morbidity and mortality associated with this condition.

Abstract

One of the factors that support plants to grow and develop optimally is the availability of sufficient and balanced nutrients and minerals. Providing nutrients that are unbalanced or not in accordance with plant needs will cause symptoms of nutrient deficiencies or nutrient deficiencies. The aims of this research are (1) To determine the symptoms of the morphological appearance of corn plants in the nutrient deficiency treatment, (2) To determine the most dominant morphological appearance of the corn plants in the nutrient deficiency treatment. The type of research used was an experiment using a randomized block design with three replications. The treatment given is the provision of nutrient solutions: complete, -Ca, -S, -Mg, -K, -N, -P, Fe, - Micronutrients and water. The planting media used are cocopeat, roasted husks and a simple hydroponic method (nutrient solution as a planting medium). The parameters observed were plant height, number of leaves, leaf length and leaf width. The results of early indication of nutrient deficiency can be clearly observed in the color of the plant leaves. Leaf chlorosis is a symptom of nutrient deficiency in plants characterized by leaves that are initially green then changes color to yellow or pale. Changes in leaf color are caused by damage or malfunction of chlorophyll.

Abstract

Hepatic cirrhosis is a chronic liver disease characterized by fibrosis and regeneration of nodules in the liver, which if it occurs for a long time, hepatocyte cells will be damaged so that they cannot function again, potentially threatening life. The prevalence of incidence and mortality depends on the progression of hepatic cirrhosis, which is influenced by the patient's etiology and treatment. The purpose of writing this article is to provide new insight into the importance of understanding the risk factor and causes of hepatic cirrhosis. This study uses a literature review approach by collecting data from online databases including Google Scholar, ProQuest, MDPI, and PubMed to search for articles discussing “Hepatic Cirrhosis”. Early detection based on clinical manifestations and appropriate treatment can reduce mortality and prevent complications that may worsen the patients condition.

Abstract

This study aims to identify the diversity of plant species used in traditional ceremonies of the Alas tribe in Babul Rahmah District, Southeast Aceh Regency, Aceh, Indonesia. The Alas tribe’s cultural practices are deeply intertwined with the use of plants in rituals such as pesijuk, tepung tawar, majun, and kendukhi khak-khak. Using a descriptive qualitative method, data were collected through field observations and semi-structured interviews with 155 informants, aged 16 to 70, selected through purposive sampling. The informants included elders, religious leaders, and community members knowledgeable about local traditions. The results identified 35 plant species from 21 families used in traditional ceremonies, with Cocos nucifera (coconut) and Areca catechu (betel nut) from the Arecaceae family being the most prominent. These plants hold symbolic significance, representing purification, life, and honor in ritual contexts. Additionally, species from the Zingiberaceae family, such as Zingiber officinale (ginger) and Curcuma longa (turmeric), are frequently used in majun ceremonies for spiritual purification and protection. The study also highlighted a decline in ethnobotanical knowledge among younger generations, with only 40% of informants aged 16–30 demonstrating extensive knowledge of the plants used in ceremonies, compared to 85% among those aged 50 and above. This decline is largely due to modernization and the lack of integration of traditional knowledge into formal education. The research underscores the importance of preserving ethnobotanical knowledge through collaboration between traditional institutions and educational bodies, emphasizing the role of tradition-based education in mitigating the loss of cultural heritage.

Abstract

Microalgae Spirulina sp. is a blue-green autotrophic organism that has a cylindrical cell structure that forms twisted filament colonies resembling spirals, and is usually used as a natural feed in aquaculture. Development has been carried out for the production of Spirulina sp. which includes culture techniques in various production scales, but the culture of Spirulina sp. cannot rely solely on the natural environment. The study aims to evaluate the effect of lighting duration on the density and growth of Spirulina sp. The lighting duration tested was 24 hours and 12 hours using the LED light, which was replicated 8 times. The density, doubling time, growth, and spirulina biomass were analyzed statistically using the T-test. The study showed that lighting duration affected (p<0,05) spirulina's density, growth, and biomass at the 48th hour of the culture period. Spirulina reached the peak of the growth at the 48th hour. The 24th-hour lighting showed a higher density of 53,615 sin per ml than the 12-hour lighting of 38.175 sin/ml. The spirulina growth of 24-hour lighting of 0,012 sin per day was higher than 12-hour lighting of 0,004 sin per day. In biomass, the 24-hour lighting resulted in 0,249+0,02 g higher than 12-hour lighting 0,143+0,07 g. However, there is no difference (p>0,05) in doubling time between 24 and 12 hours of lighting. The study suggests using 24-hour instead of 12-hour lighting to improve performance and growth.

Abstract

UV radiation from sunlight can induce the formation of free radicals, which can disrupt cellular homeostasis or DNA by triggering inflammatory signal transduction. The occurrence of inflammation in the skin can be aggravated by the presence of the bacterium Staphylococcus aureus. Previous studies have shown that the marine sponge Stylissa sp. contains an abundance of fatty acids and lipids compared to other species. Although Stylissa sp. has great potential for health applications, research on the bioactivity of lipid and fatty acid compounds from this sponge remains limited. Therefore, this study aims to explore the lipid content of Stylissa sp. as an alternative source of antibacterial agents against pathogens responsible for photoaging. The metabolite profiling of the extract was conducted using GC-MS, while the antibacterial activity was performed using the Kirby-Bauer method. Based on GC-MS profiling results, six compounds were identified in the lipid extract of Stylissa sp. namely palmitic acid, butyl glycol acetate, n-eicosylcyclohexane, isopropyl laurate, oleic acid, and 1-tetradecanol. Antibacterial evaluation of Stylissa sp. lipid extract at concentrations of 25%, 75%, and 100% showed antibacterial activity against Staphylococcus aureus, with inhibition zone diameters of 1.83, 2.17, and 2.92 mm, respectively. The results in this study have shown that the lipid extract of Stylissa sp. contains lipid compounds with potential anti-bacterial activity towards S. aureus. Future research to isolate unsaturated fatty acid compounds from the lipid extract of Stylissa sp. to achieve higher antibacterial activity is recommended.
