Effect of analog rice’s fiber on skeletal muscles GLUT4 expression in diabetic rats Background: Disruption of glucose transportation in skeletal muscle through GLUT4 becomes a problem in diabetes. Analog rice that had been modified by adding dietary fiber could improve the expression of GLUT4.Objective: This study aims to know the effect of dietary fiber toward GLUT4 expression and to know the dietary fiber percentage in analog rice.Method: The research type is true experimental with post-test only group design. The samples consist of 24 male Wistar rats that are group into 4 groups (n=6 each group). Three groups were induced by giving a high-fat diet for 40 days and streptozotocin (STZ) 35 mg/kg BW was given at 33th day and one group was not induced. After the blood glucose level exceeded 135 mg/dl, the treatment was given. After 3 weeks, the rats were terminated and quadriceps femoris muscle tissue was taken for immunohistochemistry examination using rat GLUT4 polyclonal antibody. GLUT4 expression was quantified using an immunoreactive score (IRS-GLUT4). The data were analyzed using the Kruskal-Wallis test and Spearman test.Results: Statistical analyses showed that there were significant differences between groups with a moderate positive correlation (correlation coefficient=0,651; p=0,003).Conclusion: Dietary fiber in analog rice could improve skeletal muscle GLUT4 expression in Wistar rat diabetic model.

Malaria vaccination is an essential approach to combat malaria. One major protein studied for vaccine development is Plasmodium falciparum erythrocyte membrane protein-1 (PfEMP1). It contains several important domains for malaria pathogenesis. The binding of Cysteine-rich interdomain region α1 (CIDRα1) of PfEMP1 to endothelial protein C receptor (EPCR) is associated with cerebral malaria, while CIDRα1 binding to CD36 has been correlated with uncomplicated malaria. The vital function of CIDRα1 of PfEMP1 makes it a potential vaccine candidate to prevent clinical features of malaria. A long journey of vaccine development can be shortened by the advancement of bioinformatics and biotechnology techniques. This study aimed to express the recombinant CIDRα1 of PfEMP1 and investigate its potency as a malaria subunit vaccine candidate by in silico analysis. Constructed CIDRα1-PfEMP1 was expressed in E. coli BL21(DE3) after induction with Isopropyl ß-D-1-thiogalactopyranoside (IPTG) and purified using Ni-NTA column. In silico analysis on CIDRα1 of PfEMP1 sequence was conducted using ProtParam Tool for its physicochemical properties, Iterative Threading ASSEmbly Refinement (I-TASSER) server and JPred4 program to predict secondary structure, 3D modelling, and ligand-binding site, BepiPred 2.0 and Kolaskar-Tangaonkar to predict B-cell epitope, NetCTL server to determine T-cell epitope, and Vaxijen v2.0 server to predict its antigenicity. The chimeric CIDRα1 of PfEMP1 protein had a 27 kDa molecular weight and was classified as a stable protein. The secondary structure consisted of 6 helices connected with loops. It revealed similarity to CD36-binding protein, EPCR-binding domain, and protein involved in rosetting. The 3D structure modelling demonstrated conserved ligand-binding sites and accessible surface area, which are vital for receptor binding. It had B-cell and T-cell epitopes and was non-allergenic. The properties of the chimeric CIDRα of PfEMP1 indicated its potential as a malaria subunit vaccine candidate. HIGHLIGHTS The binding capacity of CIDRα1 of PfEMP1 to endothelial protein C receptor (EPCR) and CD36 makes it a potential vaccine candidate to prevent clinical malaria The chimeric CIDRα1 of PfEMP1 protein was a stable protein and showed similarity to CD36-binding protein, EPCR-binding domain, and protein involved in rosetting, which demonstrated conserved ligand-binding sites and accessible surface area, which are vital for receptor binding The chimeric CIDRα1 of PfEMP1 protein had B-cell and T-cell epitopes and was non-allergenic in in silico analysis, indicating its potential as a malaria vaccine candidate GRAPHICAL ABSTRACT

High-level neutrophil activity and oxidative stress were reported in Acute Coronary Syndrome (ACS). Aims: This study aimed to analyze serum level neutrophil collagenase (Matrix Metalloproteinase 8, MMP-8) and oxidative enzyme NADPH Oxidase-1 (NOX-1) in ACS. Settings and Design: This study an observational cross-sectional study. Methods and Material: A total of 84 subjects were studied, consisted of 52 ACS patients (including 21 unstable angina and 15 Non-ST-Segment Elevation Myocardial Infarction [NSTEMI] and 16 ST-Segment Elevation Myocardial Infarction [STEMI]), 16 subjects with stable angina pectoris and 16 healthy control. The level of serum MMP-8 and NOX-1 were analyzed by enzyme-linked immunosorbent assay (Elisa). Statistical analysis used: Data were analyzed using Anova and LSD. Results:Level serum MMP-8 and NOX-1 were significantly (p < 0.05) higher in ACS, the highest level of both markers were found in STEMI patients. Neutrophil leukocytosis was frequently found in STEMI patients as well. Conclusions: ACS patients demonstrated sign of inflammation and oxidative stress indicated by elevated serum neutrophil collagenase and NOX-1. These evidences might provide as markers for predicting as well as a guide for preventing and developing therapy for ACS.

Perinatal death is an indicator of the success implementing a country's health services. Perinatal death rate in Indonesia in 2012 was 26/1000 live births. In 2017 there were 225 cases of infant mortality from 34,669 births in Jember Regency. Perinatal death is influenced by maternal, infant, health services and the living environment. The environmental conditions of the residence can be affected by cigarette smoke. The aim of this study was to determine the relationship of exposure tobacco smoke in pregnant women with perinatal death in Jember Regency and to find out the main source of exposure tobacco smoke in pregnant women in Jember Regency. Type of research is analytic observation with case control study design. The sampling technique is consecutive sampling. The study sample was mothers who had a dead baby in the perinatal period (perinatal death) who resided in the Jember regency on the birth of January-December 2017. The sample size was 30 for each group. Collected data was carried out by univariate analysis and bivariate analysis using the chi-square test and fisher exact test if the chi-square test requirements were not met. Results of univariate analysis in this study showed that 89.47% of the main sources of exposure tobacco smoke originated from home and 73.68% from husbands. Results of the chi-square test between exposure tobacco smoke with perinatal death p value 0.579 (p> 0.05). Confounding variables that had no significant difference between the case and control groups were parity (p = 0.116, p> 0.05), education (p = 0.083, p> 0.05), birth distance (p = 0.26, p> 0.05), and birth attendants (p = 0.492, p> 0.05). Based on the results of these studies it can be concluded that exposure tobacco smoke in pregnant women is not associated with perinatal death and the main source of exposure tobacco smoke in pregnant women comes from home and at most from husbands.   Keywords: exposure tobacco smoke, pregnant women, perinatal death

Coronary heart disease (CHD) is the cause of 7,3 million death globally in 2008. The main pathophysiology process that leads to CHD is atherosclerosis which is caused by high LDL cholesterol level. The aim of this study was to explore bay leaf and celery leaf infusion effect on reducing LDL cholesterol level in dyslipidemic rat model. The type of this study was true experimental research using wistar rat (Rattus novergicus) as the sample. The rats were induced by high fat diet and PTU for two weeks then each of the group were given either bay leaf infusion, celery leaf infusion, simvastatin (positive control), or aquadest (negative control) for a week. The measurement of LDL level used Friedewald formulation. Data was analyzed using paired sample t test and one way ANOVA. As the result there was a significance reduction on LDL level after treatment with bay leaf (p=0,013) and celery leaf infusion (p=0,035) but there was no significance difference between groups (p=0,293). It was concluded that bay leaf and celery leaf infusion could reduce the LDL level in dyslipidemic wistar rat but there was no difference on the capability of the two different leafs on reducing LDL level.

<p>Overweight, whose prevalence is increasing, is caused by unbalanced consumption patterns such as high consumption of fat and can trigger hypercholesterolemia. Analog rice (AR), which has better nutritional content than ordinary rice, is thought to have beneficial effects on health. This study aimed to determine the potential of analog rice in reducing body weight and total cholesterol levels. A total of 24 male Wistar rats were divided into four groups, namely: I) control, II) ordinary rice treatment, III) analog rice 1 treatment (PBA1) and IV) analog rice 2 treatment (PBA2). The control group was given standard feed for 40 days ad libitum. Groups II, III, and IV were given a combination induction of high-fat diet (HFD) for 40 days ad libitum and intraperitoneal injection of streptozotocin (STZ) 35 mg/kg single dose on day 33. All groups were then given the treatment of diet for three weeks according to their respective groups, namely the standard, ordinary rice, analog rice 1, and analog rice 2 feed. Body weight and total cholesterol levels were measured in the pre-induction, post-induction/pre-treatment (pre-test), and post-treatment (post-test). The results of the study showed that the induction of the HFD-STZ combination carried out resulted in a significant increase in body weight and total cholesterol levels. Measurements made after dietary therapy showed that body weight and total cholesterol levels in the I and II groups did not change significantly, whereas those in the III and IV groups decreased significantly (p&lt;0.05). This study concluded that the administration of analog rice could reduce body weight and total cholesterol levels in overweight and hypercholesterolemia rats. </p>

Treadmill is a physical exercise that caused a metabolic transition from aerobic into anaerobic. The aim of this study was to determine the effect of sodium bicarbonate to reduce fatigue and muscle pain after treadmill. This study used a time-series design with 20 selected samples from undergraduate student population of the Faculty of Medicine, Jember University. Samples consumed 100mg/kgBW NaCl (placebo) and NaHCO3 300mg/kgBW then perform a treadmil protocol until it reached maximum muscle fatigue. The results showed that the average treadmill of the treatment group (778,1±121,21 seconds) was longer than control group (717,7±93,02 seconds). The intensity of acute pain as measured by VAS (Visual Analog Scale) treatment group was lower (44,7±22,47 units) than control (55,4±19,97 units). So this study inferred that NaHCO3 can reduce fatigue and acute pain intensity after treadmill.
