Publisher : Teknik Informatika, Institut Teknologi Nasional malang

Sistem komputer modern saat ini semakin canggih dan mudah digunakan karena kompleksitas perangkat keras, dan piranti lunak, semakin tersembunyi dari pengguna. Sehingga, untuk memahami bagaimana sebuah komputer melakukan eksekusi instruksi yang dilakukan oleh mikroprosesor tidak secara mudah dilakukan. Salah satu solusinya adalah dalam bentuk piranti lunak simulator, atau emulator, suatu mikroprosesor tertentu. Penulis merancang dan membuat piranti lunak sistem komputer virtual, terdiri dari mikroprosesor virtual, dan memori virtual. Mikroprosesor virtual dirancang dan dibuat mulai dari rancangan instruction set, dengan format ukuran instruksi yang seragam 32 bits, menyediakan 16 register berukuran 32 bits. Memori virtual yang dibuat pada simulator sebesar 32 kilo bytes. Sistem komputer yang dibuat memungkinkan lebih dari satu program berada di memori, dan mikroprosesor dapat menjalankan program-program yang ada di memori tersebut, meskipun masih dieksekusi secara sekuensial. Satu program dikerjakan hingga selesai, dilanjutkan program berikutnya. Dalam simulator ini, program dapat ditulis menggunakan bahasa mesin berdasarkan rancangan instruction set yang ada, atau program ditulis berupa pseudocode yang akan dikompilasi oleh piranti lunak compiler yang telah dibuat. Menggunakan compiler ini dapat diperlihatkan hasil translasi dari pseudocode ke kode dalam bahasa assembly, juga dalam bahasa mesin, dan serta status register, maupun memori, dari tiap instruksi yang dieksekusi.

Mitral stenosis is the most common rheumatic heart disease (RHD) disorder worldwide, including in Indonesia. This pathological condition causes left atrial pressure, leading to left atrial fibrosis that affects the structure and function of the left atrial as well as the clinical condition. The aim of this study was to assess the correlation between circulating fibrosis biomarkers with net atrioventricular compliance (Cn) as a parameter of left atrial function, and left atrial volume index (LAVI) as a parameter left atrium structure of changes. A cross-sectional study was conducted at Panti Rahayu Hospital and Permata Bunda Hospital, Purwodadi, Central Java, with a total of 40 RHD patients with severe mitral stenosis. The ELISA was used to measure the levels of carboxy-terminal propeptide of type I procollagen (PICP), matrix metalloproteinase I (MMP-1), tissue inhibitor matrix metalloproteinase 1 (TIMP-1), and transforming growth factor-β1 (TGF-β1). The left atrial function was assessed by measuring Cn, and the LAVI parameters were measured to assess left atrium structure/size. The mean levels of circulating fibrosis biomarkers were as follows: PICP 153.96±89.12 ng/mL; MMP-1 1.44±2.12 ng/mL; MMP-1/TIMP-1 ratio 0.38±0.54 and TGF-β1 2.66±1.96 pg/mL. From the echocardiographic evaluation, the mean Cn was 5.24±1.93 mL/mmHg and the mean LAVI was 152.55±79.36 mL/m2. There were significant correlation between MMP-1 and MMP-1/TIMP-1 ratio with Cn (r=0.345 and r=0.333, respectively; both had p<0.05). PICP and TGF-β1 biomarkers did not significantly correlate with Cn (p>0.05). Meanwhile, none of the biomarkers had a significant correlation with LAVI (p>0.05). This study highlights that MMP-1 and MMP-1/TIMP-1 ratio are potentially to be used as markers to determine the Cn in RHD patients with severe mitral stenosis. However, further studies with a higher sample size are needed to confirm this finding.

Infections of the nervous system, such as acute bacterial meningitis, pose serious health problems that require immediate intervention. In experimental animals, exposure to lipopolysaccharide (LPS) is used to induce meningitis. Aside from drug intervention to reduce inflammation in meningitis, aerobic exercise helps to maintain the regulatory mechanisms of brain homeostasis through anti-inflammatory mechanisms. The aim of this study was to evaluate the effect of aerobic exercise on malondialdehyde (MDA), nuclear factor-kappa B (NF-κB), insulin-like growth factor 1 (IGF-1), endothelial nitric oxide synthase (eNOS), brain-derived neurotrophic factor (BDNF), apoptosis, and spatial memory. A four-week experimental study was conducted using 18 rats, which were randomly divided into three different groups (six rats per group): healthy rats as negative controls (non-meningitis), a treatment group treated with antibiotic treatment (meningitis group), and a third group (aerobic exercise group) treated with antibiotics and aerobic exercise following LPS-induced meningitis. Data were analyzed using a one-way analysis of variance (ANOVA) test, and the comparison between groups used the Bonferroni post-hoc test. The results showed that aerobic exercise significantly reduced MDA (p<0.001), NF-κB (p=0.035), and apoptosis (p=0.020) while increasing the serum levels of IGF-1 (p<0.001), eNOS (p=0.011), and BDNF (p=0.001) levels. Improvement in spatial memory was significant in the aerobic exercise group (p<0.001). This study suggested that aerobic exercise could be a promising adjunct therapy in meningitis management strategies, particularly due to its effect on improving spatial memory. Further clinical trials are needed to confirm these findings for clinical use.

Endometriosis is a gynecological disorder characterized by chronic inflammation, anatomical changes, prolonged pain, and infertility. On the other hand, Phyllanthus niruri is recognized for its pharmacological effects, which might be beneficial in managing endometriosis. The aim of the study was to investigate the pharmacological effects of P. niruri as a potential therapy for endometriosis by using an animal model. An experimental laboratory study with randomized, controlled trial, pre-test, and post-test design using 40 female Wistar rats (Rattus norvegicus) was conducted at the Integrated Research and Testing Laboratory (LPPT) of Universitas Gadjah Mada, Yogyakarta, Indonesia, from February to June 2023. Endometriosis was induced in female Wistar rats by suturing a 0.5 cm2 flap from the uterine horn to the peritoneal cavity. Changes in serum interleukin 1β (IL-1β), malondialdehyde (MDA), and matrix metalloproteinase 9 (MMP-9), before and after the treatment, were analyzed using enzyme-linked immunosorbent assay. Hematoxylin and eosin (HE) staining were used to evaluate lesion size and macrophage quantity. The results suggested that the P. niruri extract with a dose of 196 mg/200 g body weight (BW) could significantly attenuate serum IL-1β (p=0.004), MMP-9 (p=0.021), and MDA (p=0.021). Rats receiving the P. niruri extract (196 mg/200 g BW) had significantly higher macrophage counts (p=0.003), but similar lesion area (p=0.093) as compared with the negative control. In conclusion, P. niruri demonstrated promising therapeutical effects on endometriosis by modulating IL-1β, MDA, and MMP-9 levels, although the effect was not pronounced on macrophage counts and lesion area.

Increased incidence of laparoscopic cholecystectomy-related bile duct injuries (BDIs), combined with its risk of serious complications and mortality, highlights the need for a more effective repair technique. Although the use of autologous graft in BDI repair has been promoted, the role of autologous parietal peritoneum remains underexplored. The aim of this study was to evaluate the effect of autologous parietal peritoneum grafts in rabbit models of partial BDI, emphasizing its effect on the expression of cluster of differentiation 68 (CD68) and transforming growth factor-β (TGF-β). An experimental post-test-only design was employed, using 27 male New Zealand rabbits (Oryctolagus cuniculus) aged 8–10 months. The rabbits were allocated into three groups: control (primary closure), autologous parietal peritoneum graft, and autologous gallbladder graft. Partial BDI measuring 15×5 mm were surgically created and repaired according to group assignments. The expression of CD68 and TGF-β were measured via enzyme-linked immunosorbent assay (ELISA), while the anastomosis was pathologically examined through hematoxylin and eosin (H&E) staining on days 3, 7, and 14 post-surgery. Statistical analysis was performed using analysis of variance (ANOVA) followed by Bonferroni post hoc tests. No statistically significant difference was observed in the expression of CD68 or TGF-β among the three treatment groups on days 3, 7, and 14 post-surgery, indicating that the effects of autologous parietal peritoneum graft were comparable to the control and the autologous gallbladder graft in promoting wound healing. Fibroblast density on day 3 was significantly lower in the parietal peritoneum group (p=0.040), reflecting delayed recruitment, but normalized by day 14, indicating successful integration and remodeling. The study highlights the potential role of autologous parietal peritoneum grafts for BDI.

Background: Overtraining is commonly associated with elevated oxidative stress, inflammatory responses, and structural damage to muscle fibers, all of which contribute to a decline in physical performance. This study aimed to assess the impact of aerobic exercise on biomarkers including malondialdehyde (MDA), interleukin-6 (IL-6), caspase-3, nitric oxide (NO), superoxide dismutase (SOD), as well as the integrity of the sarcolemma. Methods: A six-week experimental study was conducted using 24 rats, which were randomly divided into three groups (n = 8 per group): a negative control group (no treatment), an aerobic exercise group, and a high-intensity interval training (HIIT) group. The levels of biochemical markers, including malondialdehyde (MDA), interleukin-6 (IL-6), nitric oxide (NO), and superoxide dismutase (SOD), were measured using the enzyme-linked immunosorbent assay (ELISA) technique. Additionally, the expression of caspase-3 was determined through immunohistochemical (IHC) analysis. Muscle tissue damage was evaluated by means of histopathological examination. The data were analyzed using a one-way analysis of variance (ANOVA), followed by the Mann-Whitney post hoc test to assess differences between groups. Results: The findings indicated that aerobic exercise did not result in a statistically significant reduction in malondialdehyde (MDA) (p = 0.833), interleukin-6 (IL-6) (p = 0.800), nitric oxide (NO) (p = 0.791), or superoxide dismutase (SOD) (p = 0.520) levels. Nevertheless, the aerobic exercise group exhibited a significantly lower expression of caspase-3 compared to the other groups (p = 0.023). Furthermore, aerobic exercise was associated with a significant reduction in muscle tissue damage (p = 0.001). Conclusion: The findings of this study indicate that both aerobic exercise and high-intensity interval training (HIIT) have the potential to be utilized as therapeutic approaches for mitigating exercise-induced muscle damage, primarily through their positive influence on sarcolemma stability. However, additional clinical investigations are necessary to confirm these results and establish their relevance for clinical implementation.

Background: Overtraining can elevate reactive oxygen species (ROS), suppress endogenous antioxidant activity, and trigger systemic inflammation. Monitoring oxidative stress and inflammation is essential to prevent muscle damage. This study aimed to examine the effects of an overtraining protocol on oxidative stress and inflammatory markers MDA, IL-6, NO, and SOD in male Wistar rats. Methods: The experimental was conducted over two weeks using male Wistar rats at the Bioscience Institute Laboratory, Universitas Brawijaya, Malang, Indonesia as a preliminary study. Three rats were examined to assess the effects of overtraining on MDA, IL-6, NO, and SOD levels. Observations were made one day after overtraining protocol for the intervention group value (KP) and six weeks after overtraining for the control group value (K1). Results: Three male rats underwent an overtraining protocol, and blood samples were collected one day post-overtraining (KP) to assess MDA, IL-6, NO, and SOD levels. The mean values at KP were MDA: 370.3 ± 10.3, IL-6: 5.9 ± 0.7, NO: 61.0 ± 8.4, and SOD: 0.05 ± 0.03. At six weeks post-overtraining (K1), MDA (192.8 ± 10.3), IL-6 (3.3 ± 1.9), and NO (41.7 ± 21.6) levels were lower, while SOD (0.3 ± 0.2) was higher compared to KP. Conclusion: Overtraining can elevate ROS and inflammatory responses, as indicated by increased MDA, IL-6 levels, and NO, along with reduced SOD expression.

Preeclampsia (PE) stands as a prominent cause of maternal mortality in developing nations, yet a standardized therapy for PE has not been established. Some pregnant women in Lampung have consumed the water of young kopyor coconut fruit from the Kalianda variety (WKK), although its therapeutic effects remain unexplored. This study aimed to investigate WKK phytochemicals through in vitro and silico analyses. Liquid Chromatography-Mass Spectrometry (LCMS) was employed for phytochemical analysis, while an in silico study involved Autodock, Autodock Tools, Autodock Vina, Biovia Discovery Studio 2020, and Open Babel GUI, alongside pharmacokinetics prediction using the pkCSM strategy. The study assessed the inhibitory potential of WKK on Gentiatibetine and curcumenolacto C, targeting the PE ACE2 receptor (1R24) through molecular docking with the 3D structure. Post-docking analysis, including binding affinities, hydrophobic interactions, and pharmacokinetic predictions, was conducted. WKK exhibited relatively low binding affinities for Gentiatibetine (-4.86 kcal/mol), curcumenolactone C (-2.96 kcal/mol), and aspirin (-5.12 kcal/mol). Multiple hydrophobic interactions were observed, such as Van der Waals, Salt Bridge, Conventional Hydrogen Bond, Alkyl, 162, and Lys 129. The receptor IR displayed a high bond-free energy, like aspirin docked with the same gene receptor. Pharmacokinetics predictions indicated that WKK possesses a favorable profile. In conclusion, WKK phytochemicals demonstrated a notable docking score comparable to aspirin, suggesting its potential for preventive therapy use.

Propolis is an herbal medicinal plant that contains caffeic acid phenethyl ester. This natural polyphenol compound acts as an antioxidant and can reduce blood glucose levels and increase body weight. This study aims to determine the effectiveness of Gunung Lawu propolis in lowering blood glucose levels and increasing body weight in diabetic rats. The Wistar rats were induced with STZ 45 mg/kg BW and nicotinamide 110 mg/kg BW as diabetic model rats. Research subjects were taken randomly and divided into five groups: (1) Normal, (2) DM with no propolis, (3) DM 14 days + propolis 100 mg/kg BW/day (P1), (4) DM 14 days + Propolis 200 mg/kg BW/day (P2), and (5) DM 0 day + Propolis 200 mg/kg BW/day (P3). Propolis extract was given orally once a day for 14 consecutive days (in groups 3 and 4) and 28 consecutive days (in group 5). Blood glucose levels in the treatment group (P1, P2, and P3) decreased significantly (P1: 115.28 ± 4.7 mg/dL; P2: 98.36 ± 4.8 mg/dL; and P3: 87.36 ± 4, 2 mg/dL) compared with that in the DM group (272.07 ± 3.9 mg/dL). The body weight of the treatment group (P1, P2, and P3) increased significantly (P1: 180.60 ± 5.7 g; P2: 180.60 ± 4.2 g; and P3: 208.00 ± 5.1 gr) compared with that in the DM group (160.00 ± 3.2 gr). In conclusion, Propolis is effective in reducing blood glucose levels and improving (increasing) body weight in diabetic model rats.
