    Measuring and testing dependence between random variables is of great importance in many scientific fields. In the case of linearly correlated variables, Pearson’s correlation coefficient is a commonly used measure of the correlation strength. In the case of nonlinear correlation, several innovative measures have been proposed, such as distance-based correlation, rank-based correlations, and information theory-based correlation. This thesis focuses on the statistical comparison of several important correlations, including Spearman’s correlation, mutual information, maximal information coefficient, biweight midcorrelation, distance correlation, and copula correlation, under various simulation settings such as correlative patterns and the level of random noise. Furthermore, we apply those correlations with the overall best performance to a real genomic data set, to study the co-expression between genes in serous ovarian cancer

    Market food is very popular with the people of Indonesia because the price is very affordable, tastes good and has many variations. However, market food processing often ignores cleanliness starting from the processing process to the presentation so that it can cause food to be contaminated with Escherichia coli and Salmonella sp. bacteria. Food contaminated with bacteria if consumed can harm digestion so it can also cause diarrhea. The growth of these microbes can cause food to spoil making it unfit to eat and cause poisoning in humans and even death. This study aims to examine the quality of food from microbiological exposure. This research is an experimental study using the cup count method or the pour method to analyze the microbiological quality of food ingredients with 16 samples, namely Block 8 and Block 11 in the Central Market of Gorontalo City conducted from September to October 2020. Based on the test results with 3 repetitions at different times, it was obtained that samples that did not meet the requirements were in Block 8 RM 2 in the form of woku fish, and in Block 11 there were RM 1, namely chicken curry and RM 2, namely fried fish. Keyword: Bacteria, Escherichia coli, Food Market, Salmonella s

Fourty two male male adult Wistar albino rats weighing initial mean body weight of approximately 120 ± 10g were used. The rats were divided into six groups of seven rats each with similar mean total weight. Group 1 served as normal control fed the balance diet at 14% protein level. The five groups rats were fed the the balance diet and high fat high cholesterol diet (HFHCD) at 1% cholesterol with 5% hump fat. Group 2 served as positive control. Groups 3, 4, 5 and 6 fed (HFHCD) with different types of tested herbal food plants (black seeds, curcumin roots, flax seeds and garlic at 20% level) for five weeks. Food and water were provided ad-libitum. At the end of the experiment, rats were sacrificed under ether anesthesia and blood sample was taken from orbitoocular vein from each rat. Blood samples were subjected to the determination of fasting blood glucose, serum lipid profile, serum protein and albumin, serum ALT, AST, GGT ,bilirubin, creatinine and urea. The results indicated that different types of tested herbal plants had a great effect in all parametars studied. Each of the herbal food proved to be effective to a greater extent in modifying the metabolic parameters, as compared with positive control group. Diets containing flax seed could be scored as the highest in term of modification of the metabolic parameters, from the qualitative and quantitative point of vie

    Background: Recent data suggest that there is a worldwide epidemic of vitamin D deficiency and lack of vitamin D has been linked to increased incidence of asthma and increased severity of asthma in children. Therefore, the examination of relationship between vitamin D and bronchial asthma was important.Objective: To determine serum vitamin D level in children and adolescents suffering from bronchial asthma and to detect the relationship between vitamin D level and asthma severity symptoms.Methods: This case–control study was conducted on 40 asthmatic children and adolescents, their ages ranged from 2-18 years who were attending to pediatric department at Suez Canal University Hospital, and were previously diagnosed as bronchial asthma according to the National Asthma Education and Prevention Program (NAEPP) 2007. In addition, 40 age and sex matched healthy children served as a control group. All children were subjected to history taking, clinical examination, including; anthropometric measurements, and chest examination. Serum levels of 25-hydroxyvitamin D (25OHD)[25(OH) D], total IgE level, and peripheral blood eosinophil count were evaluated.Results: The mean age of studied asthmatic children was 5.14±2.87 years. Asthma was more reported in girls than boys (55% and 45% respectively). Asthma prevalence was higher in urban than rural areas. In our study, asthmatic patients had significantly lower vitamin D levels than controls. We found that vitamin D insufficiency in 35% of studied asthmatic children. There was a statistically significant negative correlation between vitamin D level and the severity of asthma (p &lt;0.001).Conclusion: Vitamin D deficiency is relatively frequent in asthmatic patients who were attending the pediatric department at Suez Canal University Hospital. There was a significant inverse relationship between vitamin D levels and the severity of asthma symptoms.Keywords: Children, adolescences, bronchial asthma, vitamin

    AbstractBackground and purposeNeuroblastoma is the most common extracranial and deadly solid tumor in children. It accounts for 15% of the deaths from cancer in the pediatric age group. Approximately half of the newly diagnosed children are at “high risk” of treatment failure.The aim of this study is to evaluate the response rate of salvage chemotherapy by the ICE (Ifosfamide, Carboplatin, and Etoposide) regimen when administered to previously treated primary refractory or progressive high risk neuroblastoma patients.Patients and methodsSixty-six patients from the National Cancer Institute (NCI), Cairo University and the Children Cancer Hospital Egypt (CCHE) received salvage chemotherapy (ICE) either due to primary resistance in 51/66 (77.2%) or due to disease progression on primary chemotherapy in 15/66 (22.8%).ResultsThey were 40 males (60.6%) and 26 females (39.4%). Patients’ age ranged between 3months and 12.5years. The most common tumor site was suprarenal, followed by retroperitoneal mass. Two patients (3%) died from chemotherapy toxicity during ICE administration. Evaluation of tumor response in the remaining 64 patients showed the following: CR/PR in 24 patients (36.5%), SD in 11 patients (16.6%), and PD in 29 patients (43.9%).Fourteen patients (21.2%) were considered eligible for auto BMT, while 50/64 patients (78.8%) failed this second line (salvage) chemotherapy and had palliative lines of therapy.By the end of the study (May 2010), 47/66 (71.2%) of the patients were still alive, while 19/66 (28.8%) were dead. Two out of 14 patients (14.2%) who underwent HSCT died from post transplantation disease progression, while 12/14 (85.8%) were in CCR.ConclusionChemotherapy by ICE for primary resistant or progressive stage III/IV NB seems well tolerated. With a 36.6% response rate, 18% CCR, and 3% treatment mortality rate, it could be considered a good salvage therapy in the category of patients who are condemned for palliation

    Purpose: To explore the potential anticancer activities of ferulic acid (4-hydroxy-3-methoxycinnamic acid, FA) on two different human cancers cell lines, viz, breast (MCF-7) and hepatocellular (HepG2). Methods: MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) cytotoxicity, Annexin V staining, enzyme-linked immunosorbent assay (ELISA), as well as caspase-8 and -9 activation assays were used to evaluate the proapoptotic and antiproliferative potentials of ferulic acid (FA) on MCF-7 and HepG2 cell lines. Results: Ferulic acid exerted cytotoxic effects on MCF-7 and HepG2 cell lines with half-maximal inhibitory concentration (IC50) of 75.4 and 81.38 ÎĽg/mL, respectively, at 48 h. Annexin V staining revealed evidence of apoptosis. Caspase-8 and-9 levels were elevated in both cell lines after incubation with ferulic acid. Conclusion: The findings of this study suggest that ferulic acid has promising therapeutic potentials for the treatment of breast and liver cancers by inducing apoptosis via activation of caspase-8 and -9 pathways

    Get PDF
    BACKGROUND: Annona muricata (Soursop) has an antimicrobial activity toward various pathogenic microorganisms which support its ethnomedicinal for the treatment of many infectious diseases. AIM: Aim of the present study to evaluate the relation between antimicrobial activities of terpenoids extracted from different soursop parts with the isolated endophytic fungi. METHODS: Endophytic fungal species of pulp and peel of Annona fruit along with those of seeds were isolated. Salkowski test was used for qualitative screening of terpenoids in plant and the isolated endophytic Aspergillus niger strain SH3. RESULTS: Endophytic A. niger strain SH3 and Annona seed extract showed high terpenoid content indicated by the high intensity of reddish-brown colour. GC/Mass analysis revealed six compounds of terpenoids from endophytic A. niger strain SH3 extract and four compounds from seed extract with different retention times. The antimicrobial assay was performed using A. niger strain SH3 extract and Annona seed extract singly or in combinations against S. aureus, P. aeruginosa, E. coli and C. albicans. CONCLUSION: The results revealed the significant antimicrobial activity of both extracts. However, the combined extract showed some reduction in antimicrobial activity which could be attributed to the antagonistic effect exhibited by their constituents
