Abstract

Background: Starfruit (Averrhoa carambola) leaves contain flavone derivatives that exhibit anti-hyperglycemic effects. This study aims to determine the effect of starfruit leaves in reducing glucose absorption in intestinal epithelial cells of mice. Methods: This study was done by performing perfusion on the small intestines of mice. The mice that were used in this study were divided into four groups. The control group was given glucose solution without infused starfruit leaves whereas, the remaining 3 groups were given 3 mmol (540 mg/dL) glucose solution with infused starfruit leaves of varying concentrations; 200, 400, and 600 mg/kg. Samples were collected at 0, 15th, 30th, 45th, and 60th minute. The sample was tested for glucose levels using spectrophotometry. Results: Test of significance showed a significant difference between the control group and the test group with p < 0.05. Conclusions: Starfruit leaves have a reduction effect towards glucose absorption in the small intestines in Wistar strains where the group using 600 mg/kg of infused starfruit leaves have the most significant effect as compared to other groups.

Abstract

Background: Currently available molecular method to detect HER2I655V polymorphism such as PCR-RFLP is hampered by the costly experimental method, and post-PCR treatment requirement that makes this technique is not meeting for high-throughput analysis purpose. In this study, we developed an accurate, simple, low cost and rapid test to detect polymorphism at HER2 gene using SBR Green I based-melting curve method. Methods: Two forward allele-specific primers and one common reverse primer were used then these primers were tested to discriminate known genotypes of genomic templates (GG type or AA type) and genomic samples retrieved from breast cancer patients. Results: Melting curve analysis derived from SYBR Green I-based allele-specific PCR with defined primers concentration and annealing temperature at 54.3 °C showed good discrimination level of Tm peaks in which GG genotype melted at 89 °C slightly higher than AA genotype which melted at 86 °C, while AG genotype harbored both of homozygous Tm characteristics. Conclusions: This preliminary result will be as basic for further large-scale typing of HER2I655V polymorphism.

Abstract

Background: The purpose of this study was to provide a reference of chronic diabetes complications by investigating the prolonged hyperglycemia effects on hematological, biochemical and histopathological changes (liver, kidney, spleen, cardiac muscle, adrenal gland, and endocrine pancreas) in diabetic rats induced by streptozotocin. Methods: Ten adult female Sprague-Dawley of uniform age were divided into two Groups. Group 1 was made diabetic by single intraperitoneal injection of streptozotocin (60 mg/kg/bw) whereas Group 2 served as control. After six months, the rats were anaesthetized using pentobarbital. Cardiac puncture was performed to get 3 ml of the blood sample; following 12 hours of an overnight fast. Serum chemistry test and complete blood analysis for lipid profile and blood glucose test; liver and renal functions were performed. Tissue specimens of liver, kidney, spleen, cardiac muscle, adrenal gland, and endocrine pancreas were fixed in 10% formal saline and processed for histological study. Results: There were severe histopathological changes in the affected organs; and the presence of a significant abnormality of lipid profile, liver, and renal functions. Conclusions: The presence of histopathological changes with abnormal biochemical changes is related to the chronic absence of insulin production in the destroyed β-cells which reflect the diabetic complications in a human being.

Abstract

Background: Adaptation and natural selection serve as an important part of evolution. Adaptation in molecular level can lead to genetic drift which causes mutation of genetic material; one of which is polymorphism of mitochondrial DNA (mtDNA). The aim of this study is to verify the polymorphism of mitochondrially-encoded Adenosine Triphosphate synthase6gene (MT-ATP6) as one of mtDNA building blocks among tropic, sub-tropic, and polar areas. Methods: This descriptive quantitative research used 3,210 mtDNA sequences, taken from GenBank, as secondary data from 27 different populations. The data were grouped into 3 population groups based on the climates of their location. After grouping, the sequences were then aligned and trimmed using Unipro EUGENE, and analysed by Arlequin and MitoTool. Results: Results demonstrated 21 haplotypes distributed among 3 populations with variations between each climate population. In the tropic and sub-tropic populations, the dominant haplotype is h1 while h6 is dominant in the polar population. Conclusions: There is a variation of haplotype polymorphism between tropic, sub-tropic, and polar climate population.

Abstract

Background: Based on our knowledge, the study of gastrointestinal reflux disease (GERD) among certain profession has never been conducted. The aim of this study is to determine the prevalence and risk factors of GERD among Indonesian doctors. Methods: A consecutive study involving 515 doctors was conducted in October 2015. The GerdQ score was used to the diagnosis of GERD and determined its impact on daily life. All possible risk factors were also analysed. Results: A total of 515 subjects completed the questionnaire. The mean age of them was 41.37 ± 11.92 years old. Fifty-five percent of them were male and 60.6% general practitioners. The prevalence of GERD was 27.4% of which 21.0% was had GERD with low impact on daily life, and 6.4% was GERD with high impact on daily life. The statistically significant risk factors of GERD was found in age > 50 y.o (p = 0.002; OR = 2.054), BMI > 30 kg/m2 (p = 0.016; OR = 2.53), and smokers (p = 0.031; OR = 1.982). Sex and education level were not found significant statistically as the risk factors of GERD. Conclusions: The prevalence of GERD among Indonesian physician was 27.4%. We found that age over 50 y.o, obesity and smoking habit were the risk factors of GERD in Indonesian doctors.

Abstract

Background: Saliva has many properties and the buffering capacity is important for the neutralization of oral fluids. It is unclear whether stressful conditions directly affect salivary buffering capacity, and we investigated the impact of physical stress on salivary buffering capacity. Methods: Twelve participants were subjected to the physical stress of jogging and running. The salivary buffering capacity and flow rate of the participants were measured before and after exposure to stressful conditions. Salivary α-amylase activity was measured as a quantitative index of stress. Results: No change in buffering capacity was detected among each time point during the whole course under physically stressful conditions. Next, we examined the change in buffering capacity after jogging compared to baseline. Six participants showed an increase in buffering capacity (Group A), while the other six participants showed a decrease or no change (Group B) after jogging. Group B showed a decrease in flow rate and increases in α-amylase activity and protein level after jogging, whereas Group A showed no changes in these properties. Conclusions: The results suggest that salivary buffering capacity changes following exposure to physically stressful conditions, and that the changes are dependent on the stress susceptibility of individuals.

Abstract

Background: Carcinogenesis of adenocarcinoma of the prostate occurs due to dysregulation of zinc level within the cells. Intracellular zinc molecules influx is regulated by a transporter protein ZIP1, whose non-presence is predicted to inhibit apoptosis, thus leads to the development of prostate adenocarcinoma. Methods: This study was aimed to analyse the correlation of ZIP1 and Caspase-3 expression in prostate adenocarcinoma on its grading as represented by Gleason Score. This was a cross-sectional, retrospective analytical study on 31 Formalin-fixed, paraffin-embedded tissue that meets inclusion criteria. The specimen was stained using the immune-histochemistry technique for ZIP1 and Caspase-3. Protein expression of each case was counted using ImageJ analysis. Gleason score was acquired as secondary data from the cases' reports. The correlation of their expression with respect to Gleason score was analysed with Pearson's correlation using SPSS 11.5. Results: Mean expression level of ZIP1 and Caspase-3 in prostate adenocarcinoma were 35% and 33%, respectively. There was a significantly positive correlation between ZIP1 and Caspase-3 expression (r = 0.379; p = 0.018). However, their correlation was stronger in intermediate-grade group (r = 0.73; p = 0.01) and the correlation was much weaker in high-grade group (r = 0.04; p = 0.48). Conclusions: There was a positive correlation between ZIP1 and Caspase-3 expression in prostate adenocarcinoma.

Abstract

Background: There are many factors that govern growth and resistant of Salmonella typhi. A study had reported that the use of sodium benzoate caused antibiotic resistant. However, no study has directly evaluated the effect of sodium benzoate exposure on S. typhi sensitivity to chloramphenicol. The aim of this study was to evaluate the resistance or sensitivity of S. typhi to chloramphenicol after sodium benzoate exposure. Methods: The study was conducted in seven groups: three treatment groups (sodium benzoate insensitive S. typhi+8 µg/mL, 16 µg/mL, and 32 µg/mL of chloramphenicol), three positive control groups (sodium benzoate sensitive S. typhi+8 µg/mL, 16 µg/mL, and 32 µg/mL of chloramphenicol), and one negative control groups (sodium benzoate sensitive S. typhi+0 µg/mL of chloramphenicol). The effect of sodium benzoate exposure to S. typhi sensitivity to chloramphenicol was measured after 24 hours. Spearman test was used to analyzed this association. Results: In this study, we found that the average S. typhi growth in the treatment groups (A, B, C) was 445 CFU/mL, 385 CFU/mL, and 171 CFU/mL, respectively. While in the positive control group (D, E, F) was not obtained any S. typhi growth. Average S. typhi growth in the negative control group was 430 CFU/mL. Discussion: We found that sodium benzoate exposure inhibited S. typhi growth and affected S. typhi sensitivity to chloramphenicol (p < 0.05). In addition, we found that 32 µg/mL chloramphenicol had the highest mean difference value, so this showed that the dose 32 µg/mL of chloramphenicol had the best effectiveness of various treatment groups (p < 0.05). Conclusions: Sodium benzoate exposure can inhibit S. typhi growth and cause S. typhi resistant to chloramphenicol.

Abstract

Background: The aim of this research was to determine the prevalence, distribution and association of developmental alteration in tooth number with gender, location, and presence of delayed eruption of tooth among children who attended to Student's polyclinic of IIUM Kuantan, Malaysia. Methods: A cross sectional study on total 727 Orthopanthomograms (OPGs) of 3-17 years old children from April 2009 to July 2012. OPGs with presence of alteration number were scrutinized to find out the prevalence, distribution and association. The data was analyzed comparing gender, location and presence of delayed eruption and tested using Chi-square test. Results: Out of 727 OPGs, 71 OPGs showed developmental alteration in tooth number. The prevalence was 98/1000 OPGs within 3 years. Among those 71 OPGs, the gender differences were: males (49.3%) and females (50.7%). Locations were found in maxilla (45.1%), mandible (40.8%) and both (14.0%). The finding of delayed eruption was (7.0%). There were significant differences between alteration in tooth number with location as (p < 0.05) while there were no significant differences with gender and delayed eruption as (p > 0.05). Conclusions: This study showed that hyperdontia was considerably lower than hypodontia. There was association between alteration in tooth number with location, but no association with gender and delayed eruption.

Abstract

Background: Cancer is a disease that gets serious attention in the medical world. This is due to the ever increasing number of patients and there has been no effective way to treat. Cancer cells have telomerase activity is relatively high compared to normal cells, so the cancer cells have the ability to continue to proliferate. Cancer cells undergo uncontrolled mitosis and have high telomerase activity compared to cells normal. Telomerase is an enzyme responsible for telomere length, a segment of DNA that is the tip of chromosomes in eukaryotic cells. Telomeres are associated with the process of ageing and carcinogenesis. The purpose of this study was to determine the expression of telomerase in some cells such as breast cancer, cervical cancer, and lung cancer. Methods: The research method is experimental studies in several cancer cell cultures in the form of cell line. Cancer cells used were: HeLa (cervical cancer), MCF7 and T47D (breast cancer), WiDr (lung cancer), and Raji (lymphoma) with culture medium RPMI, DMEM, and M199. Vero cells is used (fibroblast cells) as a control (normal cells). Expression of telomerase enzyme was measured by the Immunohystochemistry (IHC) method. Results: The results showed that the cancer cells have activity/higher telomerase expression were highly significant (p < 0.01) compared to normal cells (Vero cells). Similarly, the expression of telomerase in HeLa versus WiDr, WiDr versus T47D, T47D versus Raji, and Raji versus MCF7 also showed highly significant differences (p < 0.01). Telomerase expression between cancer cells that showed significant difference (HeLa cells versus Raji cells; HeLa cells versus MCF7 cell; T47D cells versus MCF7 cells) (p<0.05). No significant difference was found in the group of HeLa cells versus T47D, WiDr versus Raji cells, and WiDr versus MCF7. Conclusions: It was concluded, that the cancer cells have telomerase expression of specific and different from each other, depending on the type of cell. T47D breast cancer cells have telomerase expression of the highest, followed by cervical cancer cells (HeLa). Lung cancer cells (WiDr) with cell lymphoma (Raji) has almost the same expression and both have lower expression.
