Abstract

Two chalcone derivatives i.e. (E)-1-(4-aminophenyl)-3-(2,3dimethoxyphenyl)-prop-2-en-1-one (Compound-1), and (E)-1-(4-aminophenyl)-3-phenylprop-2-en-1-one) (Compound-2),has been proven to have potential cytotoxic activity. The aim of this study was toevaluate the effect of these compounds on PI3K/Akt signalling pathway in K562 celllines. After incubation with the tested compounds, AKT, caspase-3, STAT3 and cyclinD1 concentrations were measured using ELISA. Furthermore, cell cycle was analysedusing flowcytometry. Imatinib and isotretinoin were used as positive control, whereascell culture without treatment was used as negative control. The AKT concentration aftertreatment with Compound-1 and -2 was significantly lower than that control, imatiniband isotretinoin (p<0.05). The apoptotic indices after treatment with Compound-1 and-2 were significantly higher than control, however they were lower than imatinib andisotretinoin (p<0.05). The caspase-3 concentration after treatment with Compound-1 at5 and 10 μg/mL and Compound-2 at 10 μg/mL was significantly higher than that controland imatinib, however it was lower than isotretinoin (p<0.05). The STAT3 concentrationafter treatment with Compound-1 and -2 was significantly lower than that control andisotretinoin at 50 μg/mL (p<0.05) and similar with imatinib (p>0.05). The cyclin D1concentration after treatment with Compound-1 and -2 was significantly lower than thatcontrol, imatinib and isotretinoin (p<0.05). In addition, Compound-1 and -2 arrested G0/G1 and G2/M phase in K562 cell lines, with comparable results to imatinib and isotretinoin.In conclusion, the mechanism of cytotoxic activity of Compound-1 and -2 are through thePI3K/Akt signalling pathway inhibition, apoptosis induction by upregulation of apoptoticmarkers, and inhibition of cell cycle progression by regulating cell cycle-related factors.

Abstract

Pediatric sensorineural hearing loss can cause delay in speech and daily socialcommunication. The causative factors are infectious or non infecious. The role ofinfectious risk factors in pediatric sensorineral hearing loss has been proven. However,the role of non infectious factors has not been reported, yet. The aim of the study was toevaluate the role of non infectious factors in pediatric sensorineural hearing loss (SNHL).This was a case control study using data collected from outpatients and medical recordsin Dr. Sardjito General Hospital, Yogyakarta from June to December 2015. The inclusioncriteria of case group were children with SNHL and aged 0 – 5 years old, whereasthe inclusion criteria of control group was children with normal hearing and aged 0-5years old. The exclusion criteria were children with history of infectious risk factors andhead trauma. Hearing status were determined by Otoacoustic Emission Testing (OAE)and Brainstem Evoked Response Auditory (BERA), based on a= 5%, b = 20%; ORasumption = 3.0. Sixty two subjects were selected with 31 subjects in each group.Multivariate analysis showed that low birth weight (LBW) (p=0.018; OR=6.553; 95%CI=1.38 – 31.13) and asphyxia (p= 0.041; OR=6.448; 95% CI=1.077 – 38.595)were risk factors, while hyperbilirubinemia (p= 0.382; OR=2.46; 95% CI=0.365 –13.805) and gestation (p=0.876; OR=0.831; 95% CI=0.081 – 8.483) were not riskfactors for pediatric SNHL. In conclusion, LBW and asphyxia are risk factors for pediatricSNHL, whereas prematurity and hyperbilirubinemia are not risk factors.

Abstract

The mortality rate of acute mesenteric ischemia (AMI) is high due to the delay in diagnosis.Determination of potent biomarker for early AMI is the key in reducing the mortality. As aproinflammatory cytokine, the level of TNF-α might be affected during the ischemia andreperfusion, with the prediction duration of 60-120 min. High TNF-α level may stimulatethe upregulation of IL-10 as an inhibitor of TNF-α. This provides a new opportunity forearly diagnosis of AMI by measuring the ratio between those two cytokines. The purposeof this study was to investigate the effect of duration of the mesenteric artery to theratio of TNF-α/IL-10 in a AMI rat model. This was an experimental study using Wistarrat. We performed mesenteric artery in 28 male rats to produce an AMI model, withligation duration of 0, 30, 60, 90, 120, 150, and 180 minutes. At the end of ligation,blood samples were taken for measurement of TNF-α and IL-10 level using ELISA. For themicroscopic examination of tissue necrosis, intestinal organ samples were taken and madeinto paraffin blocks and stained using Haematoxylin-Eosin. TNF-α increased in minute 120compared to other treatment groups (p<0.05). IL-10 increased in minute 180 comparedto control group (p<0.05). Microscopic examination showed that the duration of ligationaffects the structure and morphology of intestinal mucosa characterized by discolorationof organs along with increasing the ligation duration. Ligation of the superior mesentericartery was found to be significantly increased the TNF-α level and to be compensated byincreasing IL-10. It is assumed that when the IL-10 level, that has protective effect as aninhibitor, higher than TNF-α level as a proinflammatory cytokine on duration 150 minutes,it means no more inflammatory or cells is dead. Therefore TNF-α/IL-10 ratio can be usedas a biomarker candidate of prognosic factor management of AMI.

Abstract

Complications after open heart surgery may threaten patient’s survival rate. Theintraoperative methylprednisolone administration alone shows controversial resultson open heart surgery complications. Similarly, the intraoperative and preoperativemethylprednisolone administration as well as the use of hemofilter in open heart surgeryis still controversial. This study aimed to evaluate the effect of hemofilter, preoperativeand intraoperative methylprednisolone administration on complications following openheart surgery. This was a Prospective Randomized Open-Blinded Evaluation (PROBE)experimental study. Ninety-five patients who had open heart surgery in Dr. SardjitoGeneral Hospital, Yogyakarta, and Integrated Cardiac Care of Dr. Cipto MangunkusumoGeneral Hospital, Jakarta within the period of December 2011 to May 2012 wereinvolved in this study. The patients were divided into two groups i.e. group A, 48 patientsreceived methylprednisolone 15mg/kg intraoperatively, methylprednisolone 5mg/kgpreoperatively, and hemofilter, while group B, 47 patients received methylprednisolone15mg/kg intraoperatively alone. From the total 95 patients, we found 26 (27.4%)patients experienced complications i.e. 19 in group B (40.4%) and 7 in group A(14.6%). The differences of the complications were statistically significant (p<0.05;OR=3.97; 95%CI=1.476-10.71). Complications risk decreased by 63.9% in the groupA compared to the group B with the hazard ratio of 3.2. In conclusion, the application ofhemofilter, preoperative and intraoperative methylprednisolone might decrease the risk ofcomplications after open heart surgery.

Abstract

Electrocardiography (ECG) is a non-invasive technique that is used to diagnose heartabnormalities. ECG records all heart activities and represent them using bio electricsignals. Arrhythmia is one of the cardiac disorder that can be detected using ECG.Arrhythmia need to be detected early because of an early symptom of heart diseaseas deadly as coronary heart disease and heart failure. Arrhythmia described using thedifference between the R-peaks based on QRS complex. Therefore, R-peaks detection willbe an important factor that can be used to classify arrhythmia disease. One of the widelyused methods to detect R-peaks is Pan-Tompkins method. Pan-Tompkins method used athreshold value approach to get all location of R-peaks point from the ECG signals. Thisstudy proposed a development based on Pan-Tompkins method by change the thresholdvalue using normalize technique and moving windows approach to get all location ofR-peaks point from the ECG signals. This study uses MIT-BIH arrhythmia dataset. Thismethod can show the R-peaks detection with 99.83% sensitivity and 0.40% total errorrate detection. Hence, this method has potential to be used for classifying arrhythmiadisorder based on the R-peaks point.
