Abstract

BACKGROUND: Generally ameloblastoma is a locally aggressive, slow growing, non-metastatic epithelial odontogenic benign tumor. However, rarely some ameloblastoma can metastasize in spite of a benign histologic appearance. Targeting ameloblastoma by inducing it into apoptosis could be a beneficial strategy, since many ameloblastoma cases were reported recurrent after surgical therapy.CONTENT: To investigate ameloblastoma in cellular aspect,cytological pattern of ameloblastoma was divided intoouter layer/peripheral and inner layer/central cells. Tumor necrosis factor (TNF)-α, Fas ligand (FasL), TNF receptor (TNFR)1/death receptor (DR)1, TNFR2/DR2, DR4, DR5andFas were highly expressed in central than peripheral cells. Despite inducing apoptosis, TNF-α can induce PI3K leading to Akt and p44/42 mitogen-activated protein kinases (MAPK) activation in AM-1 cells, which later induce cell survival and proliferation. Therefore apoptotic induction in ameloblastoma should be suggested in higher TNF-α concentration. Expression of FasL and Fas are closely associated with squamous metaplasia and  granular transformation of the tumor cells, suggesting that apoptosis induced by FasL may play a role in the terminally differentiated or degenerative ameloblastoma cells. TNF-related apoptosis-inducing ligand (TRAIL) has emerged as an apoptotic inducing anticancer agent in tumor cells specifically. TRAIL induced activation of caspases, lowering mitochondrial membrane potential, high number of apoptotic cells in ameloblastoma cells. Therefore, TRAIL could be a potential agent for targeting ameloblastoma, although further study should be explored.SUMMARY: Targeting ameloblastoma by inducing it into apoptosis could be achieved effectively, although some criteria should be considered. Therefore understanding the underlying apoptosis signaling pathways are necessary for inducing ameloblasotma into apoptosis. Investigations on other apoptosis-related molecules, potential apoptosis-inducing natural products, and novel approach in reprogramming, are important in the future for a better anagement of ameloblastoma.KEYWORDS: ameloblastoma, apoptosis, TNF, Fas, TRAIL, Akt, MAPK, caspase

Abstract

BACKGROUND: N-acetyltransferase-2 (NAT2) enzyme, encoded by NAT2 gene, plays a key role in metabolism of anti-tuberculosis (TB) drug isoniazid. Polymorphisms in NAT2 gene may result in different responses to TB therapy. Since TB prevalence in the eastern part of Indonesia is high, the aim of this study is to explore the distribution of NAT2 gene polymorphisms among population from Kupang, Nusa Tenggara Timur.METHODS: A total of 234 respondents were included from Kupang in 2012. Polymorphisms of NAT2 gene were examined using mass screening platform and the genotypes distribution were presented in percentage. To confirm NAT2 gene polymorphisms, polymerase chain reaction (PCR)-sequencing was performed in a subset of population.RESULTS: The polymorphisms of NAT2 gene showed that the distribution of rs1801279 for GG genotype was 100%; whereas the genotype distribution of rs1799930 for GG, GA and AA was 57%, 35.1% and 7.9%, respectively. In a subset of individuals (n13), acetylator status was well determined by PCR-sequencing, resulting in individual with wild type fast acetylator (NAT2*4; n4), intermediate (NAT2*4/*5 or NAT2*4/*6 or NAT2*4/*7; n7) and poor acetylators (NAT2*6/*6 or NAT2*7/*7; n2).CONCLUSION: The amino acid change in rs1799930 result in intermediate and poor acetylator status in Kupang population. This may lead to suboptimal response of TB therapy. Assessing acetylator status before TB therapy is important and may serve as personalized INH therapy.KEYWORDS: NAT2 gene, polymorphism, acetylator status, Kupang

Abstract

BACKGROUND: Type 2 diabetes mellitus (T2DM) is a long-term illness that affects the patient's quality of life and requires substantial health care costs. Lifestyle relatedto physical exercise is one of the causes of the increasing prevalence of this disease. However, not all T2DM patients can perform physical exercise because very weak physical conditions such as elderly, spinal cord injury or diabetic secondary complications can be contraindicated when physical exercise performed. The aim of this study is to observe the used of electrical stimulation in T2DM patients.METHODS: The provision of ES to lower extremity muscles was given for 30 minutes in the intervention group. Blood glucose samples were taken before and after the ES intervention. The data collected was statistically analyzed by using paired T-test and expressed in mean±standard error.RESULTS: The ES intervention decrease blood glucose level significantly from 193.03±5.740 mg/dL to 170.66±5.200 mg/dL (p≤0.001) in the last session.CONCLUSION: The effect of ES in lower extremity is shown to be significantly lowers the blood glucose level in T2DM patients.KEYWORDS: blood glucose, electrical stimulation, physical exercise, type 2 diabetes mellitus

Abstract

BACKGROUND: Low back pain (LBP) mostly caused by disc degeneration, reflects to a tremendous of health care system and economy. More knowledge about these underlying pathologies will improve the opportunities that may represent critical therapeutic targets.CONTENT: Basic research is advancing the understanding of the pathogenesis and management of LBP at the molecular and genetic levels. Cytokines such as matrix metalloproteinases, phospholipase A2, nitric oxide, and tumor necrosis factor-α are thought to contribute to the development of LBP. Mesenchymal stem cells (MSCs) transplant to cartilage-like cells and secrete extracellular matrix and encourage nucleus pulposus (NP) cell activity inhibiting NP cell apoptosis, together with some chemical mediators such as cytokines and growth factors become a safe and effective new strategy for intervertebral disc degeneration (IDD) treatment and regeneration.SUMMARY: IDD occurs where there is a loss of homeostatic balance with a predominantly catabolic metabolic profile. A basic understanding of the molecular changes occurring in the degenerating disc is important for practicing clinicians to help them to inform patients to alter lifestyle choices, identify beneficial or harmful supplements, or offer new biologic, genetic, or stem cell therapies.KEYWORDS: low back pain, intervertebral disc, degeneration, nucleus pulposus, annulus fibrosus, extracellular matrix, genetic, stem cells

Abstract

BACKGROUND: Chronic infection with high-risk type of human papillomavirus (HPV) can cause cervical cancer. Previous studies showed that multiple infections of HPV are found in cervical cancer caused by multiple HPV infections and the most common are HPV-16 and HPV-52. The origin of HPV-16 circulating in Indonesia varies. The purpose of this study was to explore the origin of multiple infections of HPV-52 and HPV-16 in cervical cancer by using a phylogenetic tree.METHODS: During July-November 2010, 100 women were diagnosed with cervical cancer in the Department of Obstetrics and Gynecology, Dr. Hasan Sadikin General Hospital, Bandung, Indonesia. Only 96 patients were involved in this study. Ninety-six samples of HPV deoxyribonucleic acid (DNA) were isolated from biopsied tissue of cervical cancer. Multiple infections of HPV genotypes HPV-16 and HPV-52 were confirmed by using the linear assay for HPV genotyping test. Afterward,HPV-52L1 gene was amplified by using self-designed primer. L1 gene was also sequenced and analyzed using phylogenetic program (MEGA6.06).RESULTS: The result of phylogenetic tree construction showed that isolated HPV-52 originated from multiple infections of HPV-16 and HPV-52 from cervical cancer patients in Bandung were in a subgroup with isolates originating from EU077219 Canada (America) and KT799980 southwest China (Asia). Isolate HPV-16 in one subgroup with isolates originating from KU951191.1 (Southwest China).CONCLUSION: L1 gene sequence from multiple infections isolated from HPV-16 and HPV-52 from cervical cancer patients in Bandung refers to the variation of L1 gene reported from Canada and southwest China. This proves that Indonesia’s HPV clusters are located in the strains found in America and Asia.KEYWORDS: multiple infections, HPV-16, HPV-52, L1 gene, phylogenetic

Abstract

BACKGROUND: Mamuju area in West Sulawesi considered as the high natural background radiation area in Indonesia. Our previous study showed that the mean mitotic index (MI) and nuclear division index (NDI) in lymphocytes of Botteng Village, Mamuju inhabitants was lower compared to control samples. To validate our previous study results, here in this study the evaluation of cell proliferation markers which were MI and NDI in peripheral blood lymphocytes (PBL) of Takandeang Village inhabitants was conducted.METHODS: A total 60 people were enrolled in this study, consisted of 35 samples from Takandeang Sub-Village and 25 from normal background radiation area. MI was calculated manually and automatically using Metafer 3.11.2 imaging system. The NDI defined as proportion of mononucleated, binucleated, trinucleated and tetranucleated cells were conducted using cytokinesis block micronucleus (CBMN) assay.RESULTS: The results of this study showed that the mean manual MI in Takandeang Sub-Village inhabitants was lower compared to control group (4.96±2.25 vs. 5.93±2.14). In contrast, the mean automatic MI (20.37±10.49 vs. 18.87±7.49) and NDI (1.555±0.174 vs. 1.523±0.112) in Takandeang Sub-Village inhabitants was higher compared to the control group. Statistical analysis revealed that the difference of mean manual MI, automatic MI and NDI in Takandeang Sub-Village inhabitants was not significantly different compared to the control group(p>0.05).CONCLUSION: It can be concluded that based on this study the chronic low radiation dose exposure in Takandeang Sub-Village, Mamuju has no significant effect on the lymphocytes proliferation.KEYWORDS: lymphocytes, mitotic index, nuclear division index, high background radiation

Abstract

BACKGROUND: Redox and proteotoxic stress contributes to age-dependent accumulation of dysfunctional mitochondria and protein aggregates, and is associated with neurodegeneration. The free radical theory of aging inspired many studies using reactive species scavengers such as alpha-tocopherol, ascorbate and coenzyme-Q to suppress the initiation of oxidative stress. However, clinical trials have had limited success in the treatment of neurodegenerative diseases (NDDs).CONTENT: The misfolding and aggregation of specific proteins is a seminal occurrence in a remarkable variety of NDDs. In Alzheimer’s disease, the two principal aggregating proteins are β-amyloid (Aβ) and tau. The abnormal assemblies formed by conformational variants of these proteins range in size from small oligomers to the characteristic lesions that are visible by optica lmicroscopy, such as senile plaques and neurofibrillary tangles. Pathologic similarities with prion disease suggest that the formation and spread of these proteinaceous lesions might involve a common molecular mechanism, corruptive protein templating. The accumulation of redox modified proteins or organelles cannot be reversed by oxidant intercepting antioxidants and must then be removed by alternative mechanisms. Autophagy serves this essential function in removing damaged or dysfunctional proteins and organelles thus preserving neuronal function and survival.SUMMARY: Senescent cells and their senescence-associated secretory phenotypes (SASPs) may constitute a novel, understudied, and potentially important contributor to neuro-inflammation and subsequent neurodegeneration. Characterization of cellular senescence in the brain could uncover novel therapeutic targets for the prevention and treatment of chronic age-related NDDs.KEYWORDS: brain, aging, neurodegeneration, DNA damage, senescence, neuro-inflammation, mitochondria, lysosome, proteostasis, prion, amyloidosis

Abstract

BACKGROUND: Polycystic ovary syndrome (PCOS), a common reproductive endocrinologic disorder in woman, was considered to be related to sleep disturbance. This study is aimed to analyze the correlation between excess androgen markers and Athens Insomnia Scale (AIS) in PCOS.METHODS: This observational, cross-sectional study of PCOS was conducted to 31 subjects to evaluate the correlation between serum total testosterone, sex hormone binding globulin (SHBG) and free androgen index with the incidence of sleep disturbance using AIS. Sleep disturbance was present if the score ≥6. The correlation between excess androgen markers and sleep disturbance was analyzed using Pearson’s coefficient of correlation or Spearman’s rho test. Correlation coefficient more than 0.5 with p<0.05 was considered significant.RESULTS: Out of 31 PCOS subjects aged 20-40 years, 39% subjects had AIS score ≥6. Mean serum testosterone in AIS score >6 group was higher than AIS score <6 group but not statistically significant (46.68 vs. 28.49 ng/mL, p>0.05). No significant correlation was found between serum total testosterone, SHBG and free androgen index with AIS score. After adjusting for AIS score, there was the moderate positive correlation between serum total testosterone level although not statistically significant (r=0.54, p=0.07).CONCLUSION: The serum total testosterone level might influence the occurrence of sleep disturbance in PCOS.KEYWORDS: PCOS, androgen excess, testosterone, sleep disturbance, Athens Insomnia Scale

Abstract

BACKGROUND: Diptheria cases are treated with both anti-diphtheria serum (ADS) and antibiotics. Penicillin and erythromycin are the primary choices for any Corynebacterium diphtheriae (C. diphtheriae) infection. Antibiotic susceptibility pattern of C. diphtheriae has not been reported in Indonesia since 1982. The improper use of antibiotics, as well as, the consumption of antibiotics without prescription, will increase the resistance of C. diphtheriae. This study aims to determine the susceptibility pattern and the effectiveness of C. diphtheriae to several antibiotics.METHODS: A total of 57 C. diphtheriae isolates were recultured by using Blood Agar (BA) and Cystine Tellurite Blood Agar (CTBA). Afterward, these isolates were identified by using API Coryne. The antibiotic susceptibility pattern was determined by using Kirby Bauer Method based on CLSI M45-A2.RESULTS: These studies revealed that as the primary choice of diphtheria cases, 10.5% of C. diphtheriae isolates were resistant to Penicillin and 5.3% were resistant to erythromycin. Seven isolates (12%) showed resistance to more than one antibiotics, such as tetracycline and clindamycin, vancomycin and clindamycin, penicillin and tetracycline, also penicillin and vancomycin. Moreover, 4 isolates (7%) were resistant to 3-5 antibiotics. All isolates were susceptible to moxifloxacin and linezolid.CONCLUSION: Some C. diphtheriae isolates were resistant to penicillin and erythromycin, which are known as the primary choice for the treatment of C. diphtheriae infection. Even though, all isolates susceptible to moxifloxacin and linezolid.KEYWORDS: Corynebacterium diphtheriae, resistance, antimicrobial
