Abstract

Cerebral malaria is the worst complication of malaria caused by Plasmodium spp. This disease is spread in tropical and subtropical countries and can attack all age groups and genders. The peak incidence occurs in preschool children and very often causes death in children. The endemic areas of malaria in Indonesia include NTT, Maluku, West Papua and Papua. Every year, as much as 40% of the total global population lives in or visits endemic areas every year. Cerebral malaria can cause long-term neurocognitive complications that can reduce quality of life. The speed of treatment determines the patient's prognosis. Therefore, it is necessary to understand the signs of malaria and the complications that can arise. This article was written to discuss cerebral malaria as a whole based on existing literature.

Abstract

Hypertension is the condition of a person whose blood pressure is above the normal limit according to medical regulations, namely greater than 140/90 mmHg. Hypertension is a major risk factor for cardiovascular disease, stroke, kidney failure and the main cause of death throughout the world. Consuming foods that are high in fat, carbohydrates, fiber and sodium can increase the occurrence of hypertension. This study aims to determine the effect of food on the incidence of hypertension. This research uses several relevant literature from various references and focuses on risk factors for hypertension, one of which is food. The references used came from searches on NCBI, Pubmed, Google Scholar, and Science Direct and 25 data-based sources were obtained. The results of this research are that there is an influence between food sources such as carbohydrates, fat and sodium which can increase the occurrence of hypertension and high fiber consumption which helps to reduce the occurrence of hypertension. Excessive sodium consumption causes the sodium concentration in the extracellular fluid to increase. And consuming excess carbohydrates can cause triglyceride levels in the blood to increase, causing carbohydrates to be converted into fat. High fat levels can cause atherosclerosis which will ultimately lead to hypertension. The conclusion is that consuming foods high in carbohydrates, fat and sodium can cause hypertension and high fiber consumption can help minimize the occurrence of hypertension.

Abstract

A giant cell tumor of bone (GCTB) as known as a benign bone tumor (neoplasm) is aggressive locally and frequently recurs, and it is characterized by the growth of mononuclear stromal cells and datia cells that resemble osteoclasts. GCTB has varying incidence rates and has been shown to have high mortality. GCTB patients have several treatment options, but the majority of patients still experience recurrence and even metastasis to other organs. This literature review aims to explain more deeply about Giant Cell Tumor (GCT) starting from the definition, etiology, epidemiology, pathogenesis, clinical manifestations and treatment options so that patients get a better prognosis. This literature review was conducted using the keywords "Giant Cell Tumor AND pathogenesis AND clinical manifestation" from PubMed dan Google Scholar. The results of the literature review carried out are that the molecular and biological pathogenesis of GCTB consists of 4 processes, namely tumorigenesis of neoplastic mononuclear stromal cells, generation of reactive multinucleated giant cells, bone resorption/migration, and bone matrix remodeling for angiogenesis, invasiveness, and metastasis. Besides, the histological picture of GCTB contains "reactive" osteoclasts such as multinucleated giant cells (Giant Cells/GC), round cells such as macrophages and spindle stromal cells such as "neoplastic" fibroblasts (mononuclear stromal cells/SC) which are important findings in establishing the diagnosis. In conclusion, staging and management are very important to produce a better prognosis and reduce recurrence rates in GCTB patients.

Abstract

In Indonesia, many people eat pariah as a vegetable. This plant can not only be consumed as a vegetable, but can also be used for medical purposes. Sample collection was carried out using purposive sampling technique. Samples taken were pariah fruits suspected of being infested by frugivorous fly pests. Sampling was done once in four different fields for each commodity. There were five types of frugivorous flies found on peria fruit, namely Z. cucurbitae, Z. calumniatus, Z. tau, A. Orientalis, and flies of the family Lonchaeidae species Silba sp. The highest proportion of flies found from peria fruit was Z. cucurbitae. The highest single percentage infestation of flies on peria fruit was A. orientalis. A. orientalis has the potential to infest fruit singly on peria fruit because it has the highest percentage of single infestation compared to other frugivorous flies. Parasitoids found were Psyttalia sp. and Fopius arisanus. Further research needs to be done on the single infestation of A. orientalis and Lonchaeidae, especially on peria fruit by inserting the flies into caged fruit at different maturity levels and varieties, so that it can be proven whether A. orientalis and Lonchaeidae can infest fruit singly on peria fruit and cucumber and how to control them so that the population level can be suppressed.

Abstract

Gili Trawangan is one of the popular marine tourism destinations and conservation areas in the West Nusa Tenggara Province. Increased human activity in the Gili Trawangan is associated with increased pressure on aquatic ecosystems. Human activity pressure comes from tourism activities and negative impacts due to various community activities around the waters can reduce water quality. Changes to water quality can be seen from the abundance and composition of phytoplankton. This is because phytoplankton plays an important role in a water body, namely as a primary producer in the food chain and has the ability to respond to the changes of the environment factors. This rearch was conducted to determine the abundance and composition of phytoplankton community structure in Gili Trawangan, North Lombok. Seawater samples were taken using a 20 µm plankton net by filtering 100 L of water. The filtered water samples were then preserved using formalin in 4% concentration. Data were analyzed by calculating the abundance of individuals, diversity (H'), uniformity (E), and dominance (D). The results showed that the average abundance of phytoplankton species was 1026.296 Ind/L and 22 genera of phytoplankton were identified. Species diiversity index (H'=2.58) is classified as medium. Species uniformity index (E=0.88) and species dominance index (C=0.10). Based on the results of this research it can be concluded that the waters of Gili Trawangan North Lombok are classified as oligotrophic waters.

Abstract

Cancer is a non-communicable disease and one of the highest causes of human death. It has been well documented that active substances have been shown in vitro to have anticancer properties. The purpose of this article is to examine the therapeutic implications of active substances involved in colorectal anticancer activity. We looked through the databases of PubMed, Science Direct, and Google Scholar in our systematic review to find papers released between 2013 and 2023. Ten studies were selected and published between 2013 and 2023. From the results obtained on plant data used as colorectal anticancer, it was reported that plants contain active phenolic compounds, flavonoids, alkaloids, gallic acid, saponins, triterpenoid/steroid, hydroquinones, triterpenoids, phenols, glycosides, quercetin, kaempferol, artemisinin, and tannins that can act as colorectal anticancer agents and are proven to be an inhibitor of cell line growth in colorectal cancer.
