  • Stable archaeal tetraether lipid liposomes for photodynamic application:
           transfer of carboxyfluorescein to cultured T84 tumor cells

    • Authors: Anton Oertl, Emmanouil Antonopoulos, Seruni U. Freisleben, Hans-Joachim Freisleben
      Pages: 196 - 206
      Abstract: Background: Archaeal membranes have phytanyl ether lipids instead of common fatty acid-glycerol esters in bacterial and eukaryotic cells. Sulfolobus and Thermoplasma species have unique membrane-spanning tetraether lipids (TEL), which form stable liposomes. Recently, we cultured Thermoplasma species from the Indonesian volcano Tangkuban Perahu and isolated TEL. The purpose of this in vitro study is to investigate the transfer of fluorescent dye from stable TEL liposomes to cultured colon carcinoma cells.Methods: TEL was extracted from cultured cells with chloroform-methanol (1:1), then it was fractionated and purified via diethylaminoethyl-cellulose-acetate columns and activated charcoal for the formation of stable liposomes. For the fluorescence exchange assay, TEL liposomes were loaded with water-soluble carboxyfluorescein (CF). Staining experiments were conducted with various cell cultures, and T84 colon carcinoma cells were chosen for the main experiments. Liposome stability was tested by light scattering and electron microscopic size determinations as well as by unspecific CF release at low pH (6.0–7.4) and increased temperature  (4–50°C/70°C).Results: TEL liposomes exhibit high stability and extremely low proton permeability at low pH. CF staining of cultured T84 colon carcinoma cells appeares more intensive from TEL liposomes than from dipalmitoylphosphatidylcholine liposomes.Conclusion: The results of this in vitro study demonstrate CF staining of colon carcinoma cells and high stability of TEL liposomes at low pH, matching the condition in the gastro-intestinal (GI) route and in the urogentital (UG) tract. For this reason, in vivo studies on liposomal fluorescent photosensitizers for topical application of photodynamic cancer therapy in the GI and UG tracts should be carried out.

  • Increased vimentin mRNA expression in MCF-7 breast cancer cell line after
           repeated endoxifen-treatment

    • Authors: Paramita Paramita, Melva Louisa, Nafrialdi Nafrialdi
      Pages: 207 - 13
      Abstract: Background: Epithelial mesenchymal transition (EMT) plays a significant role in the development of cancer cell resistance to drugs. Vimentin, a type III intermediate filament protein, is a marker of EMT. Vimentin's over-expression in cancer correlates well with increased tumor growth, change in cell shape and poor prognosis. Endoxifen is an active metabolite of tamoxifen  and has become a new potent agent in the treatment of breast cancer. This is a study that aimed to investigate the effect of endoxifen exposure with or without estradiol on cell viability, cell morphology and EMT progression through the analysis of vimentin mRNA expression after 4-week treatment.Methods: Endoxifen, 100 nM or 1,000 nM, with or without beta-estradiol were given repeatedly to MCF-7 cells. Cells treated with dimethyl sulfoxide (DMSO) 0.001% were used as control. After 2- and 4-week exposure, the cells were counted, analyzed for mRNA vimentin expression, and observed for morphological changes.Results: Compared to control, there were significant decreases in vimentin mRNA expressions in endoxifen and endoxifen+β-estradiol treated cells after 2-weeks, which then significantly increased after 4-week compared with the 2-week exposure. We found no change in morphology of MCF-7 cells.Conclusion: Repeated exposure of endoxifen might induce EMT progression through increased expression of vimentin in MCF-7 breast cancer cell line.

  • Prevalence of Helicobacter pylori among patients with different
           gastrointestinal disorders in Saudi Arabia

    • Authors: Mohammed S. Alhussaini
      Pages: 214 - 20
      Abstract: Background: Helicobacter pylori is an important gastrointestinal pathogen associated with gastritis, peptic ulcers, and an increased risk of gastric carcinoma. The present study was carried out to determine the relationship between this organism with different gastrointestinal ailments.Methods: 150 outpatients referrals to Saudi Arabian Medical City, Riyadh, Kingdom of Saudi Arabia was recruited in January to June 2015. Each patient was subjected to endoscopic examination. Biopsy specimens were taken from the stomach for rapid urease test and culture. Suspected H. pylori colonies were subjected to colony morphology identification, microscopical examination and biochemical reactions. The samples were also subjected to PCR to detect ureA subunit of urease gene.Results: The endoscopic examination of patients revealed normal, gastric ulcer, duodenal ulcer, gastritis, and gastric cancer with a rate of 20.7%, 20%, 24%, 33.3%, and 2%, respectively. Direct smear exam revealed that 52% of patients were H. pylori positive while culture and rapid urease test showed a prevalence of 71.33%. Fifty four biopsies (36%) were urease positive after 1 hour at room temperature, 39 (62%) after 1 hour incubation at 37°C and 14 (71.33%) after 24 hours incubation. Isolated H. pylori showed that they were catalase, oxidase, and urease positive. PCR results showed 411-bp fragment, which is indicative for the ureA subunit of urease gene.Conclusion: The prevalence of H. pylori infection was high among tested population. Strong association between H. pylori and duodenal ulcer was noticed. A 411-bp fragment indicative of the ureA subunit of urease gene was detected in all the tested isolates.

  • MMP-9, brain edema, and length of hospital stay of patients with
           spontaneous supratentorial intracerebral hemorrhage after hematoma
           evacuation along with the administration of tigecycline

    • Authors: Mohamad Saekhu, Nurhadi Ibrahim, Ina S. Timan, Amir S. Madjid, Zainal Muttaqin, Teguh A.S. Ronokusumo, Sudigdo Sastroasmoro, Hilman Mahyuddin
      Pages: 221 - 7
      Abstract: Background: The high plasma level of matrix metalloproteinses–9 (MMP-9) is believed to disrupt the blood-brain barrier (BBB) and cause brain edema, as well as increase patient’s length of hospital stay (LOS). Tigecycline showed ability to reduce the MMP-9 level on study in animals. This study aimed to evaluate whether tigecycline can reduce the plasma levels of MMP-9; brain edema; and LOS of patients with supratentorial spontaneous intracerebral hemorrhage (SSICH).Methods: A randomized clinical trial (RCT) was conducted on 72 SSICH patients who underwent hematoma evacuation in eleven hospitals in Jakarta; 100 mg tigecycline (n=35) or 2 g fosfomycine (n=37) administered intravenously before skin incision as an prophylactic antibiotics to avoid post-operative infections. Plasma levels of MMP-9 were measured in all subjects before and on the first and seventh day after the surgery. Reduction of brain edema was assessed by comparing the extent of brain edema on computed tomography scan (CT scan) before and CT scan after surgery. The length of stay (LOS) was recorded at the time of hospital discharge either survive or death. Data were analyzed using Mann-Whitney and Chi-Square test.Results: There were non-significant statistical differences between two groups in the proportion of subjects with reduced MMP-9 levels on the first day (48% vs 50%; p=0.902; OR=1.1) and seventh day after the surgery (33% vs 48%; p=0.296; OR=1.9); proportion of the subjects with brain edema reduction (86% vs 80%, p=0.58); LOS (median 12 days vs 13 days, p=0.256; LOS ≥15 days 40% vs 27%; p=0.243; OR=1.81; NNT=8).Conclusion: On SSICH patients who underwent hematoma evacuation, tigecycline did not either reduce MMP-9 levels and brain edema or shorthen LOS.

  • Indonesian local fetal-weight standard: a better predictive ability for
           low Apgar score of SGA neonates

    • Authors: Adly N.A. Fattah, Karina N. Pratiwi, Sulaeman A. Susilo, Jimmy S.N. Berguna, Rima Irwinda, Noroyono Wibowo, Budi I. Santoso, Jun Zhang
      Pages: 228 - 33
      Abstract: Background: Accurate assessment of fetal growth is one of crucial components of antenatal care. A generic reference for fetal-weight and birthweight percentiles that can be easily adapted to local populations have been developed by Mikolajczyk and colleagues. This study aimed to validate our own local percentile standard by evaluating the odds ratio (OR) of low 1st and 5th minute Apgar score for small-for-gestational age (SGA) versus those not SGA.Methods: We used the generic reference tools for fetal-weight and birthweight percentiles developed by Mikolajczyk and colleagues to create our own local standard and then defined the SGA neonates. For validation, we used the database of singleton live deliveries (2,139 birth) during January 1st to December 31st 2013 in Cipto Mangunkusumo Hospital, Jakarta, Indonesia. We compared our reference with that of Hadlock and colleagues. For every reference, the OR of Apgar score <7 at 1st and 5th minutes for infants who were SGA versus those not estimated with bivariate and multivariate analyses.Results: SGA found in 35% (748/2,139) and 13% (278/2,139) of neonates using the definition derived from Indonesian standard and Hadlock’s. OR of Apgar score <7 at 1st and 5th minutes were 3.45 (95% CI=2.56–4.65) and 3.05 (95% CI=1.92–4.83) for the Indonesian local fetal-weight standard compared with respectively 2.14 (95% CI=1.65–2.76) and 1.83 (95% CI=1.21–2.77) for Hadlock and collegues’ reference.Conclusion: Indonesian local fetal-weight standard has a better ability to predict low 1st and 5th minutes Apgar scores of SGA neonates than has the Hadlock and collegues’ reference.

  • The effects of intra-articular tranexamic acid given intraoperatively and
           intravenous tranexamic acid given preoperatively on post surgical bleeding
           and transfusion rate post total knee arthroplasty

    • Authors: Aryo N. Triyudanto, Andri M.T. Lubis
      Pages: 234 - 9
      Abstract: Background: Despite the advances in the design and fixation of implants in total knee replacement (TKR). the amount of postoperative bleeding is still an important issue that has not been resolved. This study aimed to measure the effectiveness of various tranexamic acid administration.Methods: This was a randomized controlled trial study, held from August 2014 to February 2016 at Cipto Mangunkusumo Hospital, Jakarta. Twenty two patients having TKR were divided into three groups: the control group, the tranexamic acid intra-articular-intraoperative group, and the intravenous preoperative group. Intraoperative bleeding, haemoglobin (Hb) level on preoperative to five-day-post-surgery, total drain production, total blood tranfusion needed and the drain removal timing were recorded and compared. Numerical data were analyzed by using parametric and non-parametric test, depended on the normality of the data.Results: The amount of blood transfusion needed in both the intra-articular group (200±SD 100 mL) and the intravenous group (238±SD 53 mL) were significantly different compared to those in the control group (1,016±SD 308.2 mL) (p=0.001). Meanwhile, there was no significant difference between the amount of blood transfusion needed in the intra-articular group and the intravenous group. Total drain production in the intra-articular group (328±SD 193 mL) and intravenous group (391±SD 185 mL) was significantly different compared to the control group (652±SD 150 mL) (p=0.003). No significant difference between the levels of both preoperative and postoperative haemoglobin, the amount of intraoperative bleeding, and the duration of drain usage.Conclusion: Intravenous and intra-articular tranexamic acid effectively decreased transfusion volume and drain production in patients undergoing TKR.

  • Endoscopic incision of protruding right ureterocele in a single collecting
           system: a case report

    • Authors: Rinto Hariwibowo, Harrina E. Rahardjo
      Pages: 240 - 44
      Abstract: Protruding ureterocele is a very rare case found in the literature. We are reporting a 21 year-old female with an intermittent protruding mass from urethra, accompanied by dysuria, hematuria, and recurrent urinary tract infection. Inspection of the external genitalia revealed a protruding mass from the urethra which could be reduced manually. Excretory urography showed bilateral single collecting systems, grade II hydronephrosis of the right kidney, and a cobra head appearance of the lower right pelvis. The patient was diagnosed with a protruding right ureterocele in a single collecting system, and thus, endoscopic incision of a ureterocele was performed. Ultrasonography which was carried out three weeks after the procedure confirmed no residual hydronephrosis or ureterocele in the bladder. Voiding cystourethrography (VCUG) underwent at a three-month-follow up revealed a grade 5 vesico-ureteral reflux (VUR) on the right side. Surgical reimplantation was then considered. In conclusion, endoscopic incision was safe and yielded good result for protruding ureteroceles, but the need for secondary surgery in several conditions should be considered.

  • Management of overactive bladder review: the role of percutaneous tibial
           nerve stimulation

    • Authors: Elita Wibisono, Harrina E. Rahardjo
      Pages: 245 - 54
      Abstract: Overactive bladder (OAB) is a common condition that is experienced by around 455 million people (11% of the world population) and associated with significant impact in patients’ quality of life. The first line treatments of OAB are conservative treatment and anti-muscarinic medication. For the refractory OAB patients, the treatment options available are surgical therapy, electrical stimulation, and botulinum toxin injection. Among them, percutaneous tibial nerve stimulation (PTNS) is a minimally invasive option that aims to stimulate sacral nerve plexus, a group of nerve that is responsible for regulation of bladder function. After its approval by food and drug administration (FDA) in 2007, PTNS revealed considerable promise in OAB management. In this review, several non-comparative and comparative studies comparing PTNS with sham procedure, anti-muscarinic therapy, and multimodal therapy combining PTNS and anti-muscarinic had supportive data to this consideration.

  • Epigenetic: A new approach to etiology of infertility

    • Authors: Silvia W. Lestari, Meidika D. Rizki
      Pages: 255 - 62
      Abstract: Infertility is a complex disease which could be caused by male and female factors. The etiology from both factors needs further study. There are some approaches to understanding the etiology of infertility, one of them is epigenetic. Epigenetic modifications consist of DNA methylation, histone modifications, and chromatin remodelling. Male and female germinal cells undergo epigenetic modifications dynamically during differentiation into matured sperm and oocyte cells. In a male, the alteration of DNA methylation in spermatogenesis will cause oligo/asthenozoospermia. In addition, the histone methylation, acetylation, or other histone modification may lead sperm lose its ability to fertilize oocyte. Similarly, in a female, the alteration of DNA methylation and histone modification affects oogenesis, created aneuploidy in fertilized oocytes and resulted in embryonic death in the uterus. Alteration of these epigenetic modification patterns will cause infertility, both in male and female.

  • Current situation of Helicobacter pylori infection in
           Indonesia

    • Authors: Ari F. Syam
      Pages: 263 - 6
      Abstract: The epidemiology of Helicobacter pylori (H. pylori) has been changing over the past decades. Indonesia was reported have a low prevalence of H. pylori infection compared to other countries in Asia. Some studies in Indonesia have evaluated that poor sanitation, age, religion, ethnicity are the risk factors for H. pylori infection. Compared to other diagnostic tests, the urine test will be reliable for the detection of H. pylori in Indonesia because it is non-invasive and low cost with high accuracy. Although we have already performed studies on the prevalence of H. pylori infection in several ethnics, we still have some questions that remain unclear regarding H. pylori infection in Indonesia. Therefore, we have a need to build a H. pylori center that provide facilities for culturing, evaluating antibiotic resistance, and obtaining the genotype information that may explain the differences in H. pylori infection among ethnic groups in Indonesia.
