Abstract

The use of plants as raw materials for medicinal purposes has become increasingly prevalent due to the diverse secondary metabolites they can produce. Clove leaves (Syzigium aromaticum L.) are known for their antimicrobial, antioxidant, anti-inflammatory, analgesic, anticancer, anesthetic, aphrodisiac, and antipyretic properties. This study aims to determine the levels of secondary metabolites in clove leaves using the LC-HRMS method. The results showed that the ethanol extract of clove leaves contained 34 compounds, with the compounds (-)-Caryophyllene oxide and Miquelianin having the highest chromatogram peaks at 9.714195% and 8.712299% of the compound composition, respectively.

Abstract

Muhammad Sabki City Forest Park (THKMS) is generally used as an educational tourism area. Organisms that have not been identified in the THKMS area include longhorn beetles (Cerambycidae). Longhorn beetles (Cerambycidae) are a type of insect that in its larval phase lives on rotting wood that will dry out. Longhorn beetles (Cerambycidae) are spread across several primary and secondary forests, to degraded forests, so that Cerambycidae can be used as environmental bioindicators. Collection of longhorn beetle samples (Cerambycidae) was carried out using purposive random sampling. Sampling was carried out in two utilization zones in the THKMS area, namely the moderate utilization zone and the low utilization zone. Longhorn beetle samples (Cerambycidae) were taken using the jackfruit branch trap method (Artocarpus trap) with 10 Artocarpus traps installed in each zone, and the determination of the trap location was carried out randomly. The result shows there are several species of longhorn beetles that are only found at certain stations. There are 8 species of longhorn beetles that can be found at both stations. The species that are only found at station 1 (low utilization zone) are 1 (Sybra sp.) and the species that are only found at station 2 (moderate utilization zone) are 3 species (Acalolepta rusticatrix, Acalolepta sp. and Pterolophia sp.3). Each genus has its own characteristics of morphology so that it can be distinguished based on morphological characters.

Abstract

Choledochal Cyst (CC) is a congenital anomaly characterized by the dilation of intrahepatic and/or extrahepatic bile ducts. This condition can occur at any age but is more common in infants and children, accounting for 80% of cases. This study aims to evaluate the clinical characteristics, diagnostic approaches, and optimal management options for choledochal cysts, accompanied by case variations. The method used in this study is a literature review, gathering relevant literature from various references focused on the topic of choledochal cysts. Literature searches were conducted using library search websites, including PubMed, ScienceDirect, Cochrane Library, Google Scholar, and ProQuest, with the search keyword "Choledochal Cyst." The review indicates that choledochal cysts are more common in females and people of Asian descent, especially in Japan, with the most common symptoms presenting as the classic triad of abdominal pain, jaundice, and a palpable mass in the right upper quadrant of the abdomen. This condition is more frequently diagnosed in children than in adults. Further research is needed to explore definite preventive efforts regarding this disease, as it is rare and its etiology remains uncertain.

Abstract

Indonesia, as a maritime nation, possesses numerous mangrove ecosystems that have significant potential for exploring their benefits. One species of mangrove that has attracted attention is Avicennia marina, which contains various bioactive compounds. This article aims to provide a comprehensive review of the bioactive components of the Avicennia marina plant and its biological activities, particularly its therapeutic potential and benefits in the pharmaceutical field. We conducted a literature search to find relevant articles in the PubMed, Scopus, and Google Scholar databases using the keywords: plant identification + Avicennia marina; compound identification + Avicennia marina; biological activity + Avicennia marina. The bioactive content from the leaves, fruits, stems, and roots of Avicennia marina has been shown to exhibit antioxidant, antimicrobial, anticancer, and anti-inflammatory effects. This effect is strongly correlated to the presence of active metabolites of triterpenes, terpene alcohols, diterpenes, tannins, dodecanoic acid, octadecanoic acid, phenolic compound, flavonoid, squalene, and phytol. This indicates that Avicennia marina is a promising natural source for further research in the development of a new drug. Our finding further the notion of Avicennia marina as a potential medicinal plant.

Abstract

Stunting is a major chronic nutritional problem with a high prevalence in Indonesia. This issue is crucial as it affects the quality of Indonesia's human resources in the future. One of the consequences of stunting is the increased incidence of anemia in toddlers. Anemia occurring early in life disrupts physical growth and leads to growth retardation. The relationship between anemia and stunting is an overlapping influence stemming from various levels. Efforts to prevent and reduce the rates of stunting and anemia must involve all parties comprehensively. Anemia in toddlers is a global health problem, both in terms of severity and prevalence. Globally, 1.6 million people are affected by anemia, and 47.4% of them are preschool-aged children. This study aims to determine the relationship between the occurrence of stunting and anemia in toddlers. The research was conducted through an analytical observational survey with a cross-sectional design. In this study, in the normal toddler group, of 26 samples, 25 children (96.15%) had normal Hb levels, and 1 child had mild anemia (3.85%). Meanwhile, in the 30 stunted toddlers, all samples had normal Hb levels (100%). The average Hb level in normal toddlers was 12.82 mg/dl, and in stunted toddlers, it was 12.81 mg/dl. No significant difference was found between the Hb levels of normal and stunted toddlers, with a p-value of 0.977 (p > 0.05).

Abstract

Epidemiological studies suggest a strong correlation between a history of atopy and the likelihood of developing sensitive skin. This article aims to explore the physiological mechanisms linking these two conditions. A systematic review was conducted from relevant literature using PubMed, Google Scholar, and ProQuest, with search terms such as “atopy OR atopic OR atopy history AND sensitive skin OR sensitive skin syndrome.” The findings reveal that filaggrin mutations in individuals with atopy compromise skin barrier integrity, while Th2 cytokines exacerbate inflammatory responses and hinder epidermal regeneration, thereby increasing vulnerability to irritants. These insights underscore the significant role of genetic predisposition and immune dysregulation in the higher prevalence of sensitive skin among individuals with a history of atopy.

Abstract

Anemia remains a chronic nutritional problem in Indonesia, with a relatively high prevalence. According to the 2013 Riskesdas survey, the prevalence of anemia among adolescents aged 15-24 years in Indonesia was 18.4%, which increased to 32% in subsequent years. This means that 3-4 out of 10 adolescents suffer from anemia. Research on the benefits of iron supplementation to reduce the incidence of anemia by increasing hemoglobin levels in adolescent girls has been conducted in several regions in Indonesia. However, similar studies are still rare in NTB, particularly in Mataram City. This study aims to assess the effectiveness of iron supplementation in increasing the hemoglobin levels of adolescent girls in Mataram City. This study is a quasi-experimental research with a one-group pretest and posttest design. The results showed that at the pretest, 58 samples (96.67%) had normal hemoglobin levels, while 2 people (3.33%) had mild anemia. At the posttest, 57 people (95%) had normal hemoglobin levels, 2 people (3.33%) had mild anemia, and 1 person (1.67%) had moderate anemia. The average hemoglobin level at the pretest was 14.47 mg/dl and increased to 14.75 mg/dl six weeks later (posttest). There was no significant difference in hemoglobin levels between the pretest and posttest, with a p-value of 0.210 (p > 0.05).

Abstract

Clarias sp. represent one of the most prominent aquaculture commodities in Indonesia, but the challenge in catfish aquaculture is the production of feed because it is highly vulnerable to imports. Therefore, Moringa (Moringa oleifera) leaves are considered as an alternative raw material for vegetable protein source-based catfish feed to reduce soybean imports. This research was conducted to examine the use of different proportions of Moringa oleifera fermented leaf meal in feed as substitute for soybean meal on the performance catfish (Clarias sp.). This study used a completely randomized design with five treatments and three repetition of feed A as a control (0% of fermented moringa leaves flour), feed B (75% of soybean meal flour + 25% of fermented moringa leaves flour), feed C (50% of soybean meal flour + 50% of fermented moringa leaves flour), feed D (25% of soybean meal flour + 75% of fermented moringa leaves flour) and feed E (100% of fermented moringa leaves flour). Based on the data, the supplementation of fermented moringa meal with E feed had a significant increase in absolute weight growth, specific growth rate, feed conversion rate, protein retention and fat retention and a decrease in protein efficiency ratio. The fermented moringa leaves flour with the composition of 100% can be used in catfish feed as a substitution for soybean meal flour with an average absolute weight growth is 13,16±2,54 – 15,76±1,03 g.

Abstract

Deep Vein Thromboembolism (DVT) occurs due to the formation of blood clots in the veins, characterized by the formation of thrombi along with an inflammatory response in the inner walls of the veins. DVT most commonly occurs in the deep veins of the lower extremities but can also occur, albeit less frequently, in other areas such as the arms or other forms of superficial thrombosis. This article aims to review the epidemiology, clinical presentation, diagnosis, pathophysiology, and management of deep vein thrombosis. The literature review was conducted by searching for relevant articles on deep vein thrombosis published in the past fifteen years. Literature searches were performed using Google Scholar, PubMed, and NCBI databases. The findings highlight the clinical manifestations of DVT and its potential to cause serious complications, particularly post-thrombotic syndrome. Post-thrombotic syndrome is a debilitating condition that can significantly impair patients' quality of life. Management of DVT involves both pharmacological and non-pharmacological treatments. Understanding the mechanisms of deep vein thrombosis and its management is crucial in minimizing the complications associated with this condition.

Abstract

Endophytic bacteria were produce antibacterial compounds from various plants has been widely reported as considered efficient in overcoming resistant pathogen infections. This study aims to obtain endophytic bacteria from papaya seeds which can produce antibacterials. Papaya seeds were used to isolate endophytic bacteria, which were then examined for antibacterial activity. The dics diffusion method is used to determine the antibacterial activity's efficacy against Escherichia coli and Staphylococcus aureus. There are nine isolates of endophytic bacteria in all. According to a potency test, the nine isolates exhibit strong antibacterial activity against Escherichia coli and Staphylococcus aureus, respectively. Every isolate has the ability to effectively inhibit Staphylococcus aureus. The only isolates that could suppress Escherichia coli were CPA 5, CPA 6, and CPA 8. Based on their antibacterial activity against Escherichia coli and Staphylococcus aureus, it was determined that the endophytic bacterial isolates from papaya seed have the capacity to generate antibacterials.
