Abstract

BACKGROUND: Transthyretin protein experiences misfolding and aggregation in preeclampsia due to placental ischemia and inflammation. Placental endothelial damage occurring in preeclampsia stimulates the production of larger young platelets in the bone marrow and can be reflected by an increase in the immature platelet fraction (IPF) and mean platelet volume (MPV). Since the change in these markers in preeclampsia remains controversial, this study was conducted to analyze the differences in levels of transthyretin, IPF, and MPV as easily accessible markers in normotensive and preeclampsia pregnancies.METHODS: Total subjects included in this study were 32 normotensive and 26 preeclampsia pregnant woman. The measurement of serum transthyretin level was using enzyme-linked immunosorbent assay (ELISA) method. Meanwhile, IPF and MPV levels were measured by using a hematology analyzer with flowcytometry method. Data was statistically analyzed using unpaired T-test and Mann-Whitney, with significancy of p<0.05.RESULTS: Median value of transthyretin in normotensive and preeclampsia pregnancy were 11 (6-30) mg/dL and 9 (5-18) mg/dL. The mean value of IPF in normotensive and preeclampsia pregnancy were 4.56±2.19% and 6.33±2.99%. Mean value of MPV in normotensive and preeclampsia pregnancy were 10.41±0.76 fL and 11.32±1.2 fL. There were significant differences in levels of transthyretin, IPF, and MPV between normotensive and preeclampsia pregnancies (p=0.008, p=0.017, and p=0.002, respectively).CONCLUSION: There are significant differences in transthyretin levels, IPF, and MPV values in normotensive and preeclampsia pregnancies. Therefore, serum transthyretin, IPF, and MPV can be developed as affordable parameters for the diagnosis of preeclampsia.KEYWORDS: preeclampsia, transthyretin, IPF, MPV

Abstract

BACKGROUND: Cisplatin is one of the most potent chemotherapy drugs to treat various types of cancer, however the use of cisplatin has some the adverse effect, such as the increase of oxidative stress and inflammation by malondialdehyde (MDA) and nuclear factor kappa B (NF-kB) activation. Since the dosing of cisplatin is critical, we observed the effect of single and multiple doses of cisplatin injection on rats’ inflammation and oxidative stress level.METHODS: Total of 27 male Sprague-Dawley rats were divided into 9 sub-groups, each consisted of 3 rats. The baseline sub-group received no treatments; Group 1 (sub-group 1.1, 1.2, 1.3, and 1.4) were administered one single dose of 5 mg/kg BW/intravenously (i.v) of cisplatin; and Group 2 (sub-group 2.1, 2.2, 2.3, and 2.4) were given 0.2 mg/kg BW/i.v of cisplatin twice a week for two months. Rats were observed for their body weight, NF-kB, and MDA level based on the assigned group. RESULTS: Body weight loss was observed in the 1st week after treatment for Group 1, and 7th week for Group 2. Group 1 and Group 2 showed increasing level of NF-kB and MDA since the 1st observation, which was the 1st week and 5th week, respectively. NF-kB and MDA and levels were also significantly increasing in both groups for every week of observation (p<0.05).CONCLUSION: Cisplatin injection either in single or divided dose can induce inflammation and oxidative stress thus decrease the body weight. However, dividing cisplatin in smaller dose can delay the inflammation effect on subjects.KEYWORDS: cisplatin dose, MDA, NF-kB, body weight, inflammation, oxidative stress

Abstract

BACKGROUND: Bifidobacterium is a genus of lactic acid bacteria that lives in the large intestine of humans and animals. The health benefits of this genus are well established; however, the anti-inflammatory activity of this genus, specifically Bifidobacterium lactis, has not been well defined. Therefore, in this study, we evaluated anti-inflammatory activity of B. lactis hydrolysates using lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages.METHODS: RAW 264.7 cells were cultured using Dulbecco’s Modified Eagle’s Medium in 5 % CO2 incubator at 37 ℃. One µg/mL of LPS was used to stimulate RAW 264.7 cells. Nitric oxide (NO) production, inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2) were measured to evaluate anti-inflammatory activity of B. lactis hydrolysates. The cytotoxicity of the inhibitor was also measured in present study through 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assay.RESULTS: The results showed that B. lactis hydrolysates at 25–200 μg/mL inhibited NO production. In concentration-dependent manner, B. lactis hydrolysate showed inhibition of iNOS expression. However, no inhibition on COX-2 expression was observed. The MTS assay of the B. lactis hydrolysates showed no side effects on the cell viability at all concentrations.CONCLUSION: The current study revealed that B. lactis hydrolysates possess specific anti-inflammatory effects by inhibiting iNOS expression without cytotoxicity and therefore could potentially be developed as a new iNOS inhibitor.KEYWORDS: Bifidobacterium lactis, macrophages, hydrolysates, iNOS, COX-2

Abstract

BACKGROUND: Obesity incidence has risen dramatically during the last 50 years, reaching epidemic proportions. Obesity's growing prevalence, as well as its numerous metabolic and cardiovascular problems, poses a danger to human health and lifespan across the world.CONTENT: Numerous studies have shown that obesity causes inflammation, and suggest that inflammation may have a causal role in the development of insulin resistance, defective insulin secretion, and energy homeostasis disturbance. Obesity-induced inflammation is different from other inflammatory models because it includes tonic activation of the innate immune system, which has a long-term influence on metabolic balance. Inflammation can cause tissue damage by causing maladaptive responses such as fibrosis and necrosis. Obesity-induced inflammation is unique since it affects a variety of organs, including the adipose tissue, pancreas, liver, skeletal muscle, heart, and brain. These characteristics of obesity-induced inflammation make it difficult to decipher the underlying processes and how they affect metabolic systems.SUMMARY: The disruption of energy homeostasis caused by a positive energy balance is most likely the first trigger of metabolic inflammation, and the initial adaptive response aim to relieve the anabolic pressure caused by obesity. However, over time, this adaptive reaction becomes maladaptive, and the persistence of inflammation shows that the initial response has failed. The inflammation affects so many organ systems during obesity, and to develop novel treatment methods, a greater knowledge of the process was needed.KEYWORDS: obesity, inflammation, diabetes mellitus, non-alcoholic fatty liver disease, cardiovascular diseases, heart failure

Abstract

BACKGROUND: Pterygium is an ocular surface disease that often occurs in tropical countries with a high recurrence rate. Matrix metalloproteinase-3 (MMP-3) play a key role in the inflammatory process of pterygium. This study aims to investigate the ability of curcumin and fibrin glue (FG) in suppressing the expression of MMP-3, and whether can be expected as adjuvant therapy to reduce pterygium recurrence.METHODS: Human pterygium fibroblasts (HPF) obtained from primary cultured of pterygium were treated with no treatment, curcumin, mitomycin-C (MMC), and FG. MMP-3 expression was analyzed using immunocytochemistry and the intensity measurement was done using ImageJ software. Cell migration was measured by scratching and stratification of fibroblast culture after cell confluence, and assessed for 48 hours.RESULTS: The expression of MMP-3 were lower in the HPF treated with 100 mol/mL curcumin, 200 mol/mL, and FG (2205.84±86.1 pg/mL, 1002.51±25.22 pg/mL, 1131.55±17.71 pg/mL, respectively) in comparison with untreated HPF (4703.49±108.9 pg/mL). The expression of MMP-3 were significantly different between groups (p<0.001). Cell migration of HPF after scratching with curcumin intervention at 200 mol/mL decrease from 178.67±2.85 (24 hours) to 88.83±1.48 (48 hours). Meanwhile the migration in FG group also decrease from 180.4±2.56 (24 hours) to 72.45±1.25 (48 hours).CONCLUSION: Curcumin and FG able to reduce the expression of MMP-3 and inhibit the migration of HPF cells.KEYWORDS: curcumin, mitomycin C, fibrin glue, human pterygium fibroblast, MMP-3

Abstract

BACKGROUND: The changes in vaginal acidity impact the composition of the vaginal microbiota, either commensal or pathogenic. After menopause, the vaginal tract is more susceptible to infection. Current study was conducted to analyze the effect of vaginal acidity changes on the vaginal microbiota composition in menopausal women.METHODS: A cross-sectional study was conducted on 32 subjects with vulvovaginal atrophy (VVA). Vaginal pH was measured using a strip with colorimetric examination. The detection of Candida sp. was done by using 10% potassium hydroxide. Meanwhile for detection of Trichomonas vaginalis, Gardnerella vaginalis, Lactobacillus iners, and Lactobacillus crispatus, polymerase chain reaction was performed. The data were statistically analyzed.RESULTS: G. vaginalis was the mostly found pathogenic microorganism in current study (40.63%), followed by Candida sp. (25%). Further analysis showed that G. vaginalis were found in L. crispatus positive samples for 9 cases and L. iners positive samples for 9 cases. Candida sp. had an increased risk at vaginal pH ≥6 (OR=8.273), T. vaginalis had a reduced risk at vaginal pH ≥6 (OR=0.765), G. vaginalis had an increased risk at vaginal pH ≥6 (OR=1.440), L. crispatus had an reduced risk at vaginal pH ≥6 (OR=0.077), while L. crispatus had an increased risk at vaginal pH ≥6 (OR=1.111).CONCLUSION: Vaginal acidity alterations in postmenopausal women affect either commensal or pathogenic microorganism composition. A decrease in the number of L. crispatus and an increase in the number of L. iners and pathogenic microorganisms is in line with the increase of pH.KEYWORDS: Lactobacillus, microbiota, menopause, pathogenic microorganisms, vaginal acidity

Abstract

BACKGROUND: Shigella is a Gram-negative rod-shaped intracellular bacterial pathogen that causes bacterial dysentery or shigellosis among children under five years old. Antibiotics have been less effective in treating shigellosis due to the multi-drug resistance of Shigella. Therefore, an effective vaccine is urgently needed to prevent this disease. The present study aims to determine the peptides presented by major histocompatibility complex (MHC) class II molecules of Shigella-infected macrophages using mass spectrometry-based immunopeptidomics approaches. The MHC class II-associated peptides derived from Shigella-infected macrophages are candidates for developing subunit-based Shigella vaccine.METHODS: THP-1-derived macrophages were infected with Shigella flexneri 2a at the multiplicity of infection equal to 10. The lysate was immunoprecipitated and analyzed by liquid chromatography–tandem mass spectrometry (LC-MS/MS). The sequences retrieved were analyzed using bioinformatics tools.RESULTS: The Shigella-infected THP-1-derived macrophages contained sample peptides from source proteins of almost all subcellular localizations. Eight peptides from S. flexneri 2a-infected macrophages were predicted to be localized at the outer membrane proteins (OMPs) of S. flexneri 2a by the PSORTb server. Two of the OMP-associated peptides were predicted as antigenic, non-allergenic, and non-toxic by respective bioinformatics tools.CONCLUSION: The findings in this study showed two selected OMPs have great potential for vaccine development against shigellosis.KEYWORDS: immunopeptidomics, mass spectrometry, vaccine development, Shigella, MHC peptides

Abstract

BACKGROUND: The variety of traumatic brain injury (TBI) creates difficulty in evaluating its level and the clinical outcome correctly. This study aimed to analyze the level variations and dynamic of serum biomarkers, such as tumor necrosis factor (TNF)-α, vascular endothelial growth factor (VEGF), and procalcitonin (PCT) in response to severe TBI.METHODS: Intravenous blood samples were collected from 20 TBI subjects at different time points: 0, 12, 24, and 48 hours. The serum levels of TNF-α, VEGF, and PCT were measured using specific monoclonal antibodies by quantitative sandwich enzyme-linked immunosorbent assay (ELISA).RESULTS: In 0, 12, 24, and 48 hours, the serum levels were significantly higher for TNF-α (p<0.0001), VEGF (p<0.0001) and PCT (p<0.0001) compared to the healthy control. In comparison to admission time point, TNF-α had elevated significantly (p<0.001) at 24 hours. PCT showed a significant increase after 48 hours (p<0.02) and VEGF showed no significant differences. Comparing the 3 biomarkers dynamic changes at 0, 12 and 24 hours, PCT level showed to be lower than VEGF and TNF-α levels, while VEGF level showed to be higher than PCT and TNF-α levels. However after 48 hours, PCT level (0.25 ng/mL) had elevated more than VEGF (0.21 ng/mL) and TNF- α (0.18 ng/mL) levels.CONCLUSION: Monitoring PCT in comparison to VEGF and TNF-α can be used to assist the progress of severe TBI, since PCT level progressive changes were associated with time increase.KEYWORDS: trauma, TNF-α, VEGF, PCT, Glasgow Coma Scale

Abstract

BACKGROUND:Purple sweet potato tuber ethanol extract (PSPTEE) has been known to have benefits in various disease, including to prevent nasopharyngeal carcinoma (NPC). However, there has been no research on PSPTEE in preventing the proliferation of nasopharyngeal mucosal epithelial cells induced by formaldehyde through the oxidative stress mechanisms and inflammatory process. Studies have proven the effect of PSP on various cancer cells, but the carcinogenesis process of the nasopharyngeal mucosal epithelium is still limited. Hence, this study aimed to demonstrate the mechanism for preventing histopathology changes with PSPTEE due to formaldehyde exposure.METHODS: Thirty-two formaldehyde-induced Wistar rats were treated with or without 1g/kgBW/day PSPTEE for 16 weeks. Malondialdehyde (MDA) level were examined with spectrophotometry method, while tumor necrosis factor (TNF)-α and p53 with enzyme linked immunosorbent assay (ELISA) method. The histopathology appearance of the nasopharyngeal epithelium was observed with hematoxylin-eosin (HE) staining.RESULTS: MDA and TNF-α levels in control and treatment group were 22.89±2.84 μM; 9.83±0.89 μM and 84.18±11.58 ng/L; 73.92±10.59 ng/L, respectively, and they showed significant difference. Meanwhile, the level of p53 showed no significant difference. Histopathology appearance showed a significant difference. Path analysis for MDA, TNF-α and p53 levels contributed 28.7% to histopathology appearance. MDA have an effect on significant direct effect on TNF-α. TNF-α has a significant direct effect to histopathological appearance. Indirect influence MDA on histopatological appearance were smaller than the direct effect. TNF-α has the greatest influence on histopatological appearance.CONCLUSION: Formaldehyde induces the histopathology appearance in nasopharyngeal epithelium. This study also demonstrates the mechanism to prevent the nasopharynx epithelial histopathology appearance by administration of PSPTEE.KEYWORDS: PSP, MDA, TNF-α, p53, nasopharynx epithelial

Abstract

BACKGROUND: Central obesity has a close association with inflammation and the state of bone mass. Osteopenia is an abnormal condition of bone density. Bone mass density is influenced by several factors, such as 25(OH)D, parathyroid hormone (PTH), calcium (Ca) and phosphorus (P). The aim of this study was to evaluate the role of PTH-25(OH)D and Ca-P ratio as risk factors for osteopenia in women with central obesity.METHODS: A cross-sectional study was conducted in September 2020 to March 2021. The total subjects were 130 women aged 25-50 years old with central obesity. The diagnosis of osteopenia was done using dual X-ray absorptiometry (DXA) to measure bone mineral density. Enzyme linked fluorescent assay (ELFA) method was done to measure PTH and 25(OH)D levels, ion selective electrode method to measure Ca, and photometer method to measure P level. The receiver operating characteristic (ROC) curve was used to determine the optimal cut-off value and calculated prevalence ratio (PR) for osteopenia risks, followed by logistic regression analysis.RESULTS: The PR of PTH level was 10.18 (95% CI: 1.15–5.85; p=0.01); the PTH-25(OH)D ratio was 5.12 (95% CI: 1.13–23.19; p=0.04); Ca level was 6.0 (95% CI: 1.33–27.14; p=0.02) and Ca-P ratio was 4.89 (95%CI: 1.33–17.97; p=0.02). The PR for PTH together with Ca level was 18.71 (95% CI: 2.17–160.40; p=0.008).CONCLUSION: The PTH-25(OH)D ratio and the Ca-P ratio are risk factors for the incidence of osteopenia in women with central obesity. A high PTH-25(OH)D ratio and a high Ca-P ratio would have a higher risk of developing osteopenia in this population.KEYWORDS: CRP, PTH-25(OH)D, Ca-P, osteopenia, central obesity, women
