Abstract

Protein S (PS) is Vitamin K dependant protein which plays a role in regulating the blood clotting process in the body. Protein S deficiency is explained as a condition characterized by reduced levels of protein S in the serum so that it makes the blood clot too easily. The purpose of this literature review is to give an update of protein S defficiency and the mechanism of protein s in hemostasis and atherosclerosis based on publish literature reference from various database. Protein S plays important role in hemostasis by regulating blood cloth process in the initiation phase of the extrinsic pathway as a TFPI cofactor or in the propagation phase, namely as an APC cofactor and independent activity of TFPIα and APC. Protein S deficiency is known to be associated with the occurrence of atherosclerosis via the Tyro3-Axl-Mer (TAM) receptor. The main clinical manifestations of the majority of patients with heterozygous mutations in the protein S (PROS1) gene are deep vein thrombosis (DVT) and pulmonary embolism that precipitate by VTE. Administration of anticoagulant drugs such as heparin in the form of low-molecular-weight heparin (LMWH) or unfractionated heparin, vitamin K antagonists (VKA), namely warfarin, or direct oral anticoagulants (DOACs) can be selected as a management of protein S deficiency with VTE. Protein S has a central role in the coagulation prosses and its deficiency associated with atherosclerotic conditions.

Abstract

Achalasia is a rare disease, but it can lead to loss of the lower esophageal sphincter (LES) causing many complications in the gastrointestinal tract. Achalasia has a good prognosis if treated promptly, but the symptoms are non-specific. The aim of this study was to find out more about the pathophysiology, diagnosis and management of esophageal achalasia. This study was conducted on databases, such as PubMed, Google Schoolar, and Sience Direct. Inclusion criteria were free full text published in 2017-2022. The results of the literature review obtained by achalasia can cause functional obstruction at the gastroesophageal junction. Gradual neurodegeneration due to lack of non-cholinergic inhibitory ganglion cells results in an imbalance of inhibitory and excitatory neurotransmission, resulting in over-contraction of the lower esophageal sphincter and loss of regulation leading to achalasia. Although the incidence of achalasia is very rare, if not treated promptly, it will lead to airway obstruction and cause sudden death. Therapy in patients with achalasia requires long-term follow-up, as the nature of available therapy is palliative, meaning recurrence will often occur. In conclusion, achalasia is an esophageal motility disorder that causes disruption of esophageal peristalsis and malfunction of the esophageal sphincter characterized by difficulty swallowing. Although the incidence of achalasia is very rare, if not treated immediately, it will lead to respiratory obstruction and death.

Abstract

Brain tumors are one of the most malignant tumors that occur in humans. It accounts for approximately 1.35% of all malignant neoplasms and 29.5% of cancer deaths. This article was written with the aim of knowing more about molecular biology, phatophysiology, and clinical symptoms of brain tumor. The method used is a literature review combined with a search for related sources from National Center for Biotechnology Information (NCBI), Google Scholar, and Research Gate. The results of this literature review of the articles carried out can be concluded that brain tumors often cause symptoms of physiological disorders, such as focal signs, fatigue and headaches or behavioral disorders including hallucinations, depression, anxiety, decreased attention and awareness. Brain tumors can also arise spontaneously without a family history or previous genetic inheritance pattern. In conclusion, cytogenetic and molecular abnormalities in brain tumors can be seen in numerical and structural chromosomal changes, gene amplification and overexpression, deletions and small-scale mutations and epigenetic deregulation.

Abstract

Plastic is a popular packaging material used worldwide. Plastic has advantages such as being strong, light and elastic, but due to its slow decomposition process, its existence has an impact on the accumulation of plastic waste and the environment. Bioplastics made from Gayam starch and plantain peels with variations of glycerol are the best solutions to overcome the plastic problem because they are made from easily decomposed raw materials. The purpose of this study was to determine the bioplastic prototype of gayam fruit and plantain peel with glycerol variations. This type of research is quantitative with a laboratory experiment approach. This research was conducted on 24 February 2022 to 06 January 2023 at the Ambon IAIN MIPA Laboratory. Gayam fruit starch and plantain peel starch flour were made in a ratio of 1: 3. Then precipitated for 24 hours and dried in an oven for 4 hours at 50°C. Bioplastics are made by adding variations of glycerol 5%, 10%, 15%, and 20%. Bioplastic prototypes in the form of physical appearance, biodegradable tests and water resistance were analyzed descriptively using the ANOVA test (Analysis of Variance) and continued with Duncan's test to determine the significance of glycerol variations on bioplastic prototypes. The results showed that Gayam starch and plantain peel with variations in glycerol had a significant effect (P<0.05) on the bioplastic prototype.

Abstract

Research on the population structure of Assiminea brevicula associated with mangrove vegetation in Poton Bako Bay, South Coast of East Lombok was conducted in June 2023. This study aims to determine population structure, population density, distribution patterns and the length-weight relationship of Assimineea brevicula gastropods associated with Poton Bako mangrove vegetation, South Coast of East Lombok. Data collection was carried out using the quadratic method using purposive sampling by taking into account the mangrove species found in the observation plots. As a result, the frequency of the number of Assiminea brevicula gastropods in relation to the shell length of the samples was in the size range of 6 mm - 7 mm. The maximum shell length obtained was 10 mm. From the data obtained, the highest density figure during the research was located at station 3, namely 8.24 ind/m2. The population distribution pattern of Assiminea brevicula in Poton Bako is clustered, uniform, and random with a dominant cluster pattern. The length-weight relationship on June 11 2023 obtained the equation W = 0.18L1.04 and on June 18 2023 obtained W = 0.68L0.31, and on June 25 2023 with the equation W = 0.067L1.48 because slope < 3, with a thin shape, the nature of growth is negative allometric, which means that the increase in length of the snail is faster than the increase in weight.

Abstract

Insect diversity is believed to serve as one of the bioindicators for the condition of an ecosystem.In this investigation, data pertaining to the density of mangroves were collected by extracting samples from designated stations. This was achieved by utilizing the transect line and quadrat approach, known as the Transect Line Plot method. The data were gathered through observation plots measuring 10x10 m2, aiming to document the mangrove vegetation categorized as trees.At each station, any insect samples identified were subjected to characterization based on their morphological traits, utilizing an insect identification guide.Based on the research results, there are six mangrove species among themfindings obtained through field research at four observation station sites unveiled the existence of six distinct variations of mangrove forest types within the coastal region of Wundulako District. Among these, four types belonged to the Rhizophoraceae family, specifically Rhizophora apiculata, Rhizophora Mucronata, Ceriopstagal, and Bruguiera Gymnorrhiza, . Additionally, there was one species from the Combretaceae family, Lumnitzeraand Racemosa, and another from the Sonneratiaceae family, Sonneratia Alba. Generally, the density of the mangrove ecosystem was determined to be ranging from moderate to dense.Furthermore, a scrutiny of the insect diversity index yielded values of 1.23 for Station I, 1.39 for Station II, 1.36 for station III, and 1.69 for sStation IV. Based on the findings derived from the research, it is plausible to conclude that the condition of the mangrove ecosystem in Wundulako District across the four stations varies from limited to extensive. Additionally, the outcomes from the insect diversity index suggest a relatively reduced level of insect diversity.
