Abstract

Acute ischemic stroke is an acute episode of neurological dysfunction caused by focal infarction or damage that persists for ≥24 hours in the brain, spine, and retinal. Stroke is the second highest cause of death worldwide. The total prevalence of stroke continues to increase in the world and in Indonesia. However, stroke treatment is still less effective, so adjuvant therapy needs to be developed; one of them is MLC901. However, this therapy still needs to be studied further regarding its effect on acute ischemic stroke and the biomarkers used as the prognostic factors, such as red cell distribution width (RDW). This paper aims to determine the effect of MLC901 therapy on RDW values in acute ischemic stroke by analyzing various previous studies from different databases as a reference. Increased RDW values are associated with poor outcomes of acute ischemic stroke. MLC901 was shown to have neuroprotective and neurorestorative abilities in neurons that are under stress due to ischemia. MLC901 also can reduce inflammatory responses, reduce oxidative stress, and increase erythropoietin (EPO) production. So, administration of adjuvant MLC901 therapy can reduce RDW values and improve neurological outcomes in acute ischemic stroke.

Abstract

Indigofera zollingeriana is a type of leguminous plant that is excellent for cultivation as forage for ruminant livestock such as cattle, buffalo, goats, and sheep. This study aims to determine the effect of the duration of hot water scarification on the germination of Indigofera zollingeriana seeds. The research was conducted at the Livestock Feed Technology Laboratory of the State Agricultural Polytechnic of Kupang. The study was carried out for 2 weeks using a Completely Randomized Design with 4 treatments and 5 replications, namely P0: without hot water scarification, P1: hot water scarification at 65°C for 30 minutes, P2: hot water scarification at 65°C for 60 minutes, and P3: hot water scarification at 65°C for 90 minutes. The variables measured in this study were germination percentage, mean daily germination, and seedling height. The data obtained were analyzed using analysis of variance (ANOVA), and if there was a significant effect, it was followed by Duncan's test. The results showed that the effect of scarification of Indigofera zollingeriana seeds with hot water at 65°C for different durations significantly affected the parameters of germination percentage and mean daily germination, with the treatment without scarification providing the best results. This could be due to the prolonged duration of soaking, which caused the seeds to experience heat stress. As for the seedling height parameter, the treatment did not have a significant effect. Therefore, hot water scarification with excessively long durations is not recommended as a strategy to promote germination and growth of these seeds.

Abstract

Limited understanding of rice cultivar biodiversity information in Solok Regency makes it difficult for people to determine which local rice originates from the area. This research aims to reveal the diversity and relationships of local rice, find specific morphological characters and their contribution value in providing diversity and find local rice candidates for plant breeding through analysis of potential superior characters. The method used is a field survey method with Principle Component Analysis (PCA) analysis to describe the contribution of a character in providing diversity and Cluster analysis to reveal the relationship between local rice cultivars. The 18 rice cultivars found included 11 local cultivars, 7 superior local cultivars. 3 of them from Solok Regency; Cisokan, Caredek, Siarang and the rest were released from various West Sumatra Agricultural Services. Based on the results of Cluster analysis and Principle Component Analysis, a dendogram was formed with 3 main clusters. Then we get morphological characters that have a contribution value with an eigen value> 0.3, including characters; plant height, leaf length, leaf width, ligule length, lower stem node diameter, flag leaf angle, leaf color, midrib color, flag leaf color, and center of panicle exit. This research also provides prospective local rice cultivars that have the opportunity to become superior local cultivars, such as; Padi Cinta, Situjuah, Sungkai and Talang Solok.

Abstract

Urinary Tract Infection (UTI) is a bacterial infection characterized by a urine culture showing bacteriuria with bacterial counts exceeding 100,000 per milliliter of urine. Polymerase Chain Reaction (PCR) is a method that utilizes in-vitro enzymatic reactions to amplify specific DNA targets. This process synthesizes new DNA strands complementary to the target sequences using enzymes and oligonucleotide primers within a thermocycler. The fimH gene is among the most important of the UPEC strains and is associated with severe urinary tract infections. The aim of this study was to identify the presence of the fimH gene in urine samples from UTI patients at the Puskesmas Banyuanyar in Surakarta using Polymerase Chain Reaction (PCR). The research employed the Quota Sampling Technique, collecting a total of five urine samples from individuals diagnosed with urinary tract infections. The results of the control isolates using pure Escherichia coli isolates showed that the fimH gene PCR amplified control with annealing temperature of 52°C. The analysis of clinical isolates of Escherichia coli from the urine of urinary tract infection patients revealed that the fimH gene was PCR amplified in all five samples.

Abstract

Pearl oysters, Pinctada maxima, are one of the aquaculture commodities with high economic value and Indonesia has great potential in developing pearl oysters cultivation. However, the continuity of pearl production in Indonesia is highly dependent on the success of rearing spat (pearl oyster seedlings) in the initial growth phase in the laboratory. This study aims to evaluate the impact of stocking density on the growth and survival of pearl oyster spat during rearing in the laboratory. The research was conducted using an experimental method at the Pearl Oyster Breeding Laboratory of PT. Mutiara Surya Indonesia, West Nusa Tenggara Province. Various densities of pearl oyster spat (3, 6, 9, and 12 spat/L) were tested in 3 (three) replications using a Completely Randomized Design (CRD). The results showed that the treatment had a significant effect on the growth of the dorso-ventral shell length of pearl oysters spat (p<0.05). The highest growth after 21 days of maintenance was achieved in the treatment with a stocking density of 3 spat/l with absolute growth of 6.44 mm, relative growth of 304.09%, and daily specific growth rate of 6.88%/day. The highest survival rate was obtained at a stocking density of 3 spat/l, namely 94.4%. The results indicate that lower stocking densities tend to result in best growth and good survival rates for pearl oyster spat. It is advisable to experiment with higher densities of live feed to increase the efficiency and productivity of pearl oyster cultivation containers in the future. This study contributes significantly to understanding the factors influencing the growth and survival of pearl oyster spat in the context of aquaculture.
