Abstract

Background: APOEε4 is a strong genetic risk factor for Alzheimer’€™s disease (AD). AD itself has been associated with reduced Aβ clearance from the brain and plasma. Understanding the potential pathogenic link between APOEε4 and plasma Aβ might allow for earlier identification of people at risk of developing AD. The aim of this study is to find out the correlation between APOEε4 and plasma Aβ in amnestic mild cognitive impairment (aMCI) and AD patients. Methods: This is a comparative cross-sectional study of patients attending a memory clinic in Siloam Hospital Lippo Karawaci, Tangerang, during the period of 2013-2014. Subjects were categorized into three categories: normal aging, aMCI, and AD. We performed blood test to examine APOEε4, plasma Aβ4o level, and plasma Aβ42 level. All data analyses were performed using correlation test and logistic regression. Results: Sixty subjects (normal aging = 23, aMCI = 17, AD = 20) were included. There were 19 (31.7%) subjects with APOEε4 positive. Subjects carrying ε4 allele were more likely to have AD by 3.9-fold than subjects with APOE ε4 allele negative. There is a significant difference between the mean of plasma Aβ40 in aMCI group and AD group. We also found correlation between APOEε4 (+) and higher plasma Aβ42 (p<0.05). Conclusion: There is a correlation between APOEε4 and plasma Aβ42 level, which supports the hypothesis that this genetic isoform accelerates the rate and progression of AD through Aβ-dependent pathways.

Abstract

Background: The incidence of urinary stone patient in Indonesia has increased every year in both genders. Data showed that urolithiasis was higher in male rather than female. The aimed of this study was to describe the characteristics of urinary stone found in patient who underwent extracorporeal shock wave lithotripsy (ESWL) at Cipto Mangunkusumo Hospital, Jakarta from 2008–2014. Methods: Data obtained from ESWL medical record Cipto Mangunkusumo Hospital, Jakarta from 2008–€“2014. We obtained 5,174 out of 6,020 data due to incompleteness data record. We sorted data records by gender, age, stone location, stone opacity, size of the stone, and history of ESWL, and analyzed by statistic tools (SPSS v 20 for Mac). Results: From 5,174 records, we found that the incidence of urinary stones was two times higher in male rather than female (66.3%:33.64%), occurred mostly in productive age (65.2% male, 65.9% female). Unilateral kidney stone was most common location found for both gender (50.2% male, 57.2% female), and most frequent site located in calyx inferior (24.8% male, 28.9% female). About 72.9% stone was radiopaque (73.7% male and 71.5% female). The mean size of the stone in male and female was 11.34±7.15 mm and 11.90±7.54 mm, respectively. This study also showed that 79.3% patients came for first ESWL. Conclusion: Urinary stone founds two times higher in male than female, and mostly occurs on their productive ages. Unilateral kidney stone in calyx inferior become the most common stone found in both gender. Most of the stone has radiopaque opacity.

Abstract

Primary ectopic craniopharyngioma is a rare entity. Isolated petrous apex bone location has not been reported previously. This study reports a case of 26-year-old male with right abducent nerve palsy. CT and MRI imaging reveal right petrous apex cystic lesion. No sellar or suprasellar region involvement was found. Endoscopic endonasal transphenoid approach has been successfully performed. Histopathology examination confirms the diagnosis of adamantinomatous craniopharyngioma. So far, it’s probably the first case report of primary ectopic craniopharyngioma isolated in the petrous apex. This case report supports the premise that primary ectopic craniopharyngioma is a multifactorial process that starts with an error from migrated embryological cells.

Abstract

Background: Cell proliferation occurs not only in normal but also in cancer cells. Most of cell proliferation inhibition can be done by inhibiting the DNA synthesis, notably by intervening the formation of purine or pyrimidine. In purine de novo synthesis, it was assumed that biotin plays a role as a coenzyme in carboxylation reaction, one of the pivotal steps in the purine de novo pathways. The aim of this study was to see the avidin potency to bind biotin and inhibit mitosis.Methods: Peripheral blood mononuclear cell (PBMC) was cultured in RPMI-1640 medium and stimulated by phytohemagglutinin (PHA) in the presence or absence of interleukin-2 (IL-2), with or without avidin. The effect of avidin addition was observed at 24, 48, and 72 hours for cell proliferation, viability, and cell cycle. Statistical analysis was done by one-way ANOVA.Results: Avidin inhibited cell proliferation and viability in culture under stimulation by PHA with and without IL-2. Cell cycle analysis showed that avidin arrested the progression of PBMC after 72 hours of culture. Most cells were found in G0/G1 phase.Conclusion: Inhibition of biotin utilization by avidin binding can halt cell proliferation.

Abstract

Background: Glial fibrillary acidic protein (GFAP) and heat shock protein -27 (HSP27) plasma can be used as the parameters of exercise-induced astrocyte reactivity. The American College of Sports Medicine (ACSM) recommends an exercise of 30 minutes or 10 minutes duration (each performing bout accumulated toward 30 minutes). The aim of this study was to compare GFAP and HSP27 plasma concentrations in young adults undergoing acute moderate-intensity aerobic exercise of different durations (10 minutes vs 30 minutes).Methods: An experimental study with pre-post design was conducted on 22 participants assigned to either 10 minutes or 30 minutes duration of single bout exercise. Blood sampling was performed before and after the exercise. GFAP and HSP27 plasma levels were measured with ELISA methods. Plasma GFAP and HSP27 levels before and after exercise were analyzed using paired t -test, while GFAP and HSP27 levels after exercise between the two groups were processed using unpaired t-test.Results: Plasma GFAP concentration decreased significantly (0,45 ng/mL) after 30 minutes of aerobic exercise (p<0.05). Plasma HSP27 concentration decreased significantly (1,71 ng/mL) after 10 minutes of aerobic exercise (p<0.05). No significant difference in plasma GFAP and HSP27 concentrations between 10 minutes (GFAP=0.49 ng/mL; HSP27=2.09 ng/mL) and 30 minutes duration of exercise (GFAP=0.45 ng/mL; HSP27=1,71 ng/mL).Conclusion: Acute moderate-intensity aerobic exercise with 10- and 30-minutes duration reduces the reactivity of astrocytes indication the increase of the synapse plasticity. The decrease in GFAP concentration occurred after 30 minutes of exercise and the decrease in HSP27 occurred after 10 minutes of exercise. These results showed that the body responds differently to different treatment duration in order to obtain the same effect on the body.

Abstract

Background: Graves'€™ disease (GD) is the most common autoimmune disease leading to hyperthyroidism. The role of Th1/Th2 pathways balance in GD is still controversial. Vitamin D is reported to have an effect on those pathways. This study aims to examine the effect of sunlight exposure on vitamin D 25(OH) level and Th1 and Th2 pathway-derived cytokines in GD patients. Methods: A prospective cohort study was conducted on 32 GD patients to compare the effect of sunlight exposure on vitamin D level and cytokines of Th1 and Th2 pathways between exposed and unexposed groups. Exposed group received sunlight exposure three times a week for 30 minutes each between 9–11 a.m for 1 month. Thyroid stimulating hormone (TSH), free thyroxin (fT4), vitamin D 25(OH), interferon-γ (IFN-γ) and interleukin-4 (IL-4) serum levels, were investigated before and after one month of sunlight exposure. Paired t-test or Mann Whitney test were used to analyze the difference between exposed and unexposed GD groups before and after sun exposure. Results: One month of sunlight exposure increased vitamin D 25(OH) level by 27.90% among exposed GD group (15.34 ng/mL to 19.62 ng/mL, p<0.001). Meanwhile, unexposed GD group’s vitamin D 25(OH) level decreased from 20.48 ng/mL to 18.86 ng/mL (p<0.001). Increased vitamin D 25(OH) level in exposed group was not accompanied by the increase of IL-4 level after sunlight exposure. Conclusion: Sunlight exposure increases vitamin D 25(OH) serum level and may affect the level of IL-4, Th2 pathway-derived cytokine, in patients with GD. However, the role of sunlight-derived vitamin D on IFN-γ in GD patients can not be concluded in this study.

Abstract

Background: Dimethyl sulfoxide (Me2SO) is a common cryoprotective agent widely used in cell preservation system. Me2SO is currently known to cause epigenetic changes which are critical in stem cells development and cellular differentiation. Therefore, it is imperative to develop cryopreservation techniques that protect cellular functions and avert Me2SO adverse effect. Trehalose was able to protect organism in extreme condition such as dehydration and cold. This study aimed to verify the protective effect of trehalose preincubation procedure in cryopreservation. Methods: The study was conducted using experimental design. Thawed mesenchymal (CD271+) stem cells from YARSI biorepository were used for the experiment. Trehalose preincubation was performed for 1 hour, internalized trehalose was confirmed by FTIR-ATR measurement. Three groups consisted of (1) cryopreserved without trehalose preincubation, (2) cryopreserved with trehalose preincubation, and (3) did not undergo cryopreservation were evaluated after 24 hours in LN2 for viability in culture. The absorbance from each group was measured at 450 nm. The analysis performed using paired student t test. Results: Viability of thawed mesenchymal (CD271+) stem cells that undergo trehalose preincubation prior cryopreservation was significantly higher (p<0.05) compared to group without trehalose preincubation. Higher viability observed between group with trehalose preincubation compared with controlled group suggests protection to trypsinization. Mesenchymal (CD271+) stem cells incubated for 1 hour in 100 mM trehalose supplemented medium results in 15% trehalose loading efficiency. Conclusion: These findings confirm the protective effect of trehalose preincubation in cryopreservation. Future research should be directed to elucidate the trehalose internalization mechanism and eventually the protective mechanism of trehalose in mammalian cell cryopreservation.

Abstract

Background: Q-wave myocardial infarction (QMI) has higher mortality and lower myocardial viability than non-Q-wave myocardial infarction (NQMI), suggesting the existence of pathological Q waves reflects the worse ventricular function. The aim of the study is to determine difference in left ventricular ejection fraction (LVEF) between QMI and NQMI. Methods: The study design was cross-sectional analysis conducted in patients with AMI that were hospitalized and undergone echocardiography in Abdul Wahab Sjahranie County General Hospital Samarinda during February 2014 to March 2015. Standard 12-lead electrocardiograms (ECG) were recorded at presentation, 1 day and 2 days after the onset of AMI as well as using the classical criteria for pathological Q wave. LVEF assessment was performed using echocardiography after the second day since the onset of AMI. Independent-T test was used to determine difference in LVEF using PSPPIRE 0.8.4. Results: There were 34 subjects comprising 16 QMI patients and 18 NQMI patients. QMI had a lower LVEF (42±13%) compared to NQMI (60±11%, p<0.001). The presence of pathological Q waves was associated with LVEF ≤40% (p=0.002). Conclusion: QMI had a lower LVEF than NQMI, provides information about the role of pathological Q wave as an indicator of LVEF.
