Abstract

BACKGROUND: Previous works indicated various pharmacology activities of bay plant (Syzygium polyanthum (Wight) Walp.), however only few studies investigated its toxicity. This work was aimed to study the subchronic toxicity of ethanol extract of this plant.METHODS: White Wistar rats were divided into 4 groups and were treated with 2% of Arabic gum (PGA) suspension, 1000 mg/kg of body weight (BW), 400 mg/kg of BW and 100 mg/kg of BW, respectively. The animals were observed on their body weight, hematology, clinical biochemistry parameters, organ index and histopathology.RESULTS: Flavonoids, tannins, polyphenols, saponins, quinones, monoterpenes and sesquiterpenes were detected in dried leaves and ethanol extract of bay plant. An increase of body weight in male and female groups treated with dose 100 and 400 mg/kg BW compared to controls, was observed. Moreover, there was an increase of white blood cell (WBC) in male and female groups treated with S. polyanthum extracts compared to controls, whereas a decrease of red blood cell (RBC) was observed in male groups treated with S. polyanthum extracts in dose-dependent manner compared to control. No significant changes of RBC were seen in female groups, haemoglobin values were not altered by extract treatment. Photomicrographs of liver, kidney, lungs, heart and spleen histopathology of male and female S. polyanthum extract-treated groups showed no significant alteration compared to controls.CONCLUSION: Our study revealed that S. polyanthum extracts does not show toxicity on the body weight, hematology, creatinine and serum glutamic pyruvic transaminase (SGPT), but fatty liver and necrosis are observed in female rats. This result can be beneficial for plant-based drug discovery, particularly this study provides information about the safety of S. polyanthum to be further developed as candidate of phytopharmaceutics.KEYWORDS: bay plants, salam leaves, hepatotoxicity, necrosis, SGOT, SGPT

Abstract

BACKGROUND: The mechanism of aging goes along with age, one of which is characterized by cellular senescent, which occurs mostly in adipose tissue. Adipose tissue is the site of accumulation of large cell senescent, in the regulation of obesity and aging. Proteins p53 is marker for cell senescent, which are also known to induce inflammation. This study was aimed to determine the relationship between circulating protein p53 and high sensitivity C-reactive protein (hsCRP) in central obese men with inflammaging.METHODS: The study design is an observational study with cross-sectional approach. The subjects were 75 central obese men (waist circumference/WC > 90 cm), aged ≥ 45 years old. Subjects were divided into 2 age groups, those are middle age group: 45-59 years old (50.7%) and elderly group: ≥ 60 years old (49.3%). Examination of circulating p53 was done using enzyme-linked immunosorbent assay (ELISA) method, and the hsCRP examination was done by chemiluminescent method.RESULTS: It was found that there was a correlation between circulating p53 and hsCRP in elderly (r=-0.414; p<0.05) but not in middle age (r=-0.127; p=0.449).CONCLUSION: From this study, it is assumed that more senescence cells in elderly are resulting in increased chronic inflammation.KEYWORDS: aging, senescent, inflammaging, protein p53, hsCRP

Abstract

BACKGROUND: Inflammation plays an important role in the atherosclerotic process. High-sensitivity C-reactive-protein (hs-CRP) is commonly used as inflammatory biomarker. It is well known that regular physical activity lowers hs-CRP levels, while prolonged exercise induces hs-CRP elevations. However, the relationship of training and exercise characteristics with hs-CRP levels remains not well elucidated. We evaluated baseline and post-exercise hs-CRP levels and its association with training and exercise characteristics.METHODS: Eighty-eight male endurance cyclists were involved. Demographic data, health condition and training characteristics were collected. Baseline and postexercise blood-samples were collected to determine hsCRP concentrations. A hs-CRP cut-off point of 3 mg/L was used. Blood-cell count and biochemical parameters were measured at baseline. Heart rate (HR) was measured during exercise.RESULTS: Cyclists performed 7.3 hours (interquartilerange (IQR) = 5.4-7.5) of endurance exercise at intensity of 81.8 % (IQR = 74.9-85.8). Cyclists with baseline hsCRP ≥ 3 mg/L reported higher body mass, body mass index (BMI), waist-circumference and total-cholesterol. An increase in hs-CRP was following endurance exercise. Cyclists with any elevation of hs-CRP reported a higher BMI, HR during exercise and exercise intensity. Binary logistic regression analysis showed BMI (OR = 1.24, 95% CI = 1.04-1.48) and cycling distance (OR = 0.22, 95% CI = 0.06-0.76) were associated with post-exercise hs-CRP elevations.CONCLUSION: Body mass, BMI, waist-circumference, total- and HDL-cholesterol are associated with baseline hsCRP, whereas BMI and cycling distance were associated with hs-CRP elevations. These findings suggest that anthropometry parameters and lipid levels attributed to baseline hs-CRP, while anthropometry parameters and cycling intensity attributed to post-exercise hs-CRP elevations.KEYWORDS: C-reactive-protein, exercise, endurancecycling, inflammation, acute-phase-response

Abstract

BACKGROUND: This study was conducted to investigate the prevalence of quinolone resistance associated (qnr) antibiotic resistance among Escherichia coli strains isolated from different water sources in Alborz province, Iran.METHODS: E. coli strains were isolated and identified by standard microbiological and biochemical tests from surface water sources in Alborz province, Iran in 2013. Fluoroquinolone-resistant isolates were determined using the antimicrobial susceptibility test determined by the Kirby–Bauer assay. Total genomic and plasmid DNA were extracted by boiling method. The presence of qnr genes in all nalidixic-acid and ciprofloxacin-resistant E. coli strains was determined by Polymerase Chain Reaction (PCR). The PCR amplicons were visualized after electrophoresis stained with ethidium bromide.RESULTS: One hundred E. coli strains were isolated from the water sources examined in this study. As much as 22.7% and 7.3% of the isolates were resistant to nalidixic acid and ciprofloxacin respectively. While qnrS, qnrB and qnrA genes were detected in 28%, 9% and 1% of fluoroquinolone-resistant isolates respectively. All fluoroquinolone-susceptible isolates however did not contain any of the qnr genes.CONCLUSION: This study reflects an increasing prevalence of fluoroquinolone-resistant E. coli strains in surface water sources. Underlining the importance of surface water sources as reservoirs for dissemination of potentially pathogenic E. coli and horizontal gene transfer between other waterborne bacterial species. Other possible mechanisms of resistance should also be investigated for better characterization of quinolone-resistant E. coli isolates. Therefore, immediate measures are needed to control and treat water sources more effectively.KEYWORDS: antibiotic resistance, E. coli, qnr genes, water sources

Abstract

BACKGROUND: Aminophylline (theophylline) is one of the most frequent asthma therapies in Indonesia, although it remains as a narrow therapy. The effects of drugs are individualized and strongly influenced by genetic, one of which is CYP1A2 gene polymorphisms. This study aimed to determine the profile of CYP1A2 polymorphism and theophylline level in asthma exacerbation patients receiving intravenous aminophylline therapy.METHODS: This cross sectional study was conducted in the emergency room (ER), to adults asthma exacerbation patients without complication (n=27), visiting the ER. The gene polymorphism data were compared with theophylline levels in the blood using chi-square test.RESULTS: In the CYP1A2 gene polymorphism profile, the most common heterozygous alleles are T/G genotype of CYP1A2*1E and C/A genotype of CYP1A2*1F. Most homozygote alleles exist in CYP1A2*1D and CYP1A2*1F. There was significant difference between CYP1A2*1D (p<0.005), CYP1A2*1E (p<0.023) and CYP1A2*1F (p<0.000) polymorphisms and theophylline level.CONCLUSION: CYP1A2*1D, CYP1A2*1E and CYP1A2*1F gene polymorphisms had an effect on theophylline levels. However, no one experienced an overdose theophylline, and no correlation between theophylline levels with CYP1A2 gene polymorphism.KEYWORDS: exacerbation asthma, intravenous aminophylline, CYP1A2 polymorphism gene, theophylline

Abstract

BACKGROUND: Sleep deprivation is strongly associated with cardiovascular disease (CVD) via sympathetic overstimulation and systemic inflammation in general population. However, the significance of poor sleep quality in chronic kidney disease (CKD) is still underexplored.METHODS: This study assessed the sleep quality of 39 with non-dialysis CKD (ND CKD) patients and 25 hemodialysis CKD (HD CKD) patients using the Pittsburgh Sleep Quality Index (PSQI) questionnaire. Poor sleeper was defined as individual with PSQI > 5.RESULTS: The prevalence of poor sleeper (30% vs. 60%, p=0.029) and the cummulative PSQI (ND CKD 4.5±4.4, HD CKD 8±6, p=0.038) are different between ND CKD and HD CKD groups. Among the ND CKD, there are association between short sleep duration (< 5 hours per day) with elevated diastolic blood pressure groups (r=0.421, p<0.05); habitual sleep efficiency with platelet-to-lymphocyte ratio (r= 0.532, p<0.0001); daytime dysfunction with increased hs-CRP (r=0.345, p=0.032) and neutrophil-to-lymphocyte ratio (r=0.320, p=0.046). In HD CKD group, a requirement to use sleep medication was associated with elevated highsensitivity C-reactive protein (hs-CRP) level (r=0.434, p=0.030) and decreased monocyte-to-lymphocyte ratio (r=- 0.410, p=0.042); daytime dysfunction was associated with serum hs-CRP (r=0.452, p=0.023).CONCLUSION: This study revealed that some features of poor sleep quality in CKD patients including low sleep efficiency, daytime dysfunction and requirement to use sleep medication were associated with increased diastolic blood pressure, hs-CRP and blood-count-based inflammatory predictors. Thus, this finding prompt to pay closer attention to sleep complaints in the management of CVD risk factors in CKD patients.KEYWORDS: sleep quality, chronic kidney disease, blood pressure, inflammation

Abstract

BACKGROUND: Vitamin D is an essential nutrient requirement for adults and children for normal metabolism and maintenance of healthy bones. Its deficiency may disrupt homeostasis and contribute to systemic diseases, especially in obese patients. This study aimed to examine the effect of vitamin D on insulin, fasting blood glucose (FBG) and waist-hip ratio (WHR) in young and obese Saudi females with pre-existing hypovitaminosis D.METHODS: The results of this study were based on prospective parallel randomised controlled clinical trial conducted at King Fahd University Hospital in which 30 obese Saudi young females aging 18-23 years with preexisting vitamin D deficiency contributed. Participants were randomly assigned to either vitamin D supplementation group (experimental) or placebo group (control). Subjects of vitamin D group received 50,000 IU/week of cholecalciferol drops and placebo group received 10 mL of normal saline drops for 12 weeks.RESULTS: The results of multivariate repeated measures analysis showed a change in serum 25-Hydroxycholecalciferol levels after vitamin D supplementation (F=296.132, p<0.05). There was also an indication of difference between the vitamin D group and placebo group. The only significant relationship was found between vitamin D and FBG (p<0.05). Supplementation of vitamin D improved FBG but did not contribute to improving insulin level. There was no association between vitamin D supplementation and WHR.CONCLUSION: This study concludes that supplementation of vitamin D improves FBG, but it has no contribution in improving insulin level. No association exists between vitamin D supplementation and WHR. The insignificant correlation of vitamin D intake with WHR and insulin can be attributed to the small sample size, therefore, further research is suggested with large sample size.KEYWORDS: vitamin D, fasting blood glucose, body mass index, waist hip ratio, hypovitaminosis D

Abstract

BACKGROUND: Regenerative procedure in periodontal surgery aims to improve the structure and function of the periodontium to be strong enough to support the teeth. Growth factor is essential in the process of tissue regeneration; it can be generated from the activation of Platelet-Rich Plasma (PRP). In this study, collagen was used as PRP activator. PRP release growth factor from the granules when activated. The aim of this study was to evaluate the effect of collagen on PRP activation and the collagen-activated PRP storage to fibroblast proliferation of periodontal ligament (PDL).METHODS: Fibroblasts of PDL were obtained from extracted premolar. PRP were obtained from 100 mL of blood donors using double centrifugation methods. PRP were activated by collagen and subsequently incubated for 24, 48, 72 and 168 hours; after which the lysate was taken. Fibroblasts were divided into 7 groups, which consisted of one unstimulated group as negative control, one group stimulated by PRP lysate, and five groups stimulated with PRP-collagen lysates that had been incubated for 24, 48, 72 and 168 hours. MTT assay was then performed after 1 and 3 days.RESULTS: The proliferation rate of fibroblasts group stimulated by PRP-collagen lysate was higher than the group stimulated by PRP. The storage of collagen-activated PRP for 7 days at 4°C could increase the proliferation rate.CONCLUSION: The activation of collagen on PRP and the stored collaged-activated PRP could increase the fibroblasts proliferation rate of PDL.KEYWORDS: collagen, platelet-rich plasma, fibroblasts proliferation

Abstract

BACKGROUND: Pathogenesis of severe dengue infection has not been elucidated. Immune complex of pre-existing antibodies and heterotypic dengue virus bind to FcγII (cluster of differentiation (CD32)) receptor (FcγIIR) on monocyte facilitates entry and replication of dengue virus. Aim of this study was to evaluate the expression of FcγIIR on monocytes in patients infected with dengue and in healthy subjects.METHODS: This study used a cross-sectional design that included patients infected with dengue who were hospitalized in Dr. Sardjito General Hospital, Panembahan Senopati Hospital, and Sleman Hospital, who met the inclusion criteria and selected consecutively. Examinations were completed using a lyse, no-wash method of flow cytometry. Computerized statistical analysis was conducted and was considered to be significant if p<0.05.RESULTS: Sixty-five study subjects were divided into healthy subjects (24 subjects) and patients with dengue infection (41 subjects). There were no significant differences in hemoglobin (Hb) and hematocrit (Hct) values between the groups, but differences were found in the number of leukocytes, absolute number of monocytes and platelet count (p<0.001, 0.002 and <0.001, respectively). The mean expression of FcγIIR monocytes in patients with dengue infection (208.77±32.06 median fluorescent intensity (MFI)) and the healthy subjects (124.03±47.76 MFI) with p<0.0001.CONCLUSION: The mean expression of FcγIIR monocytes in patients with dengue infection was higher than in healthy subjects.KEYWORDS: dengue infection, FcγII (CD32) receptor monocyte, flow cytometry

Abstract

BACKGROUND: Tobacco smoking plays an important role in nasopharyngeal carcinoma (NPC) risk. The Wingless-related integration site (WNT) Inhibitory Factor 1 (WIF1) as one of the tumor suppressor gene (TSG), functions to control cell proliferation through suppression of WNT signaling pathway. WIF1 methylation is one of epigenetic mechanisms which causes overactivated of WNT pathway in NPC development. WIF1 methylation from buffy coat related to smoking status and NPC risk is not known yet.METHODS: This was a nested case-control study involving 39 newly diagnosed NPC patients and 40 healthy controls. All subjects were enrolled at Dr. Sardjito Hospital, Yogyakarta. Subjects were male, with known smoking status, duration, and quantity of cigarette consumed. Parallel DNA isolated from buffy coat was used for WIF1 DNA methylation analysis, by using methylation-specific PCR (MSP) method. Chi-square analysis was used to determine distribution of differences among groups. Two tailed p-value≤0.05 was considered as statistically significant.RESULTS: No significant difference between WIF1 methylation of cases and controls (p=0.30), nor smoking habit among smokers (p=0.51) and non-smokers (p=0.43).CONCLUSION: WIF1 methylation from buffy coat could not be used as an NPC marker nor as a smoking behavior marker.KEYWORDS: buffy coat, cigarette smoking, methylation, nasopharyngeal carcinoma, WIF1
