METHODS: Stool samples were collected prospectively from symptomatic adults who had elective colonoscopy from September 2014 to January 2016 and were analyzed with the ScheBo M2-PK Quick test and laboratory detection of fecal hemoglobin.
RESULTS: The results were correlated to the colonoscopy findings and/or histopathology report. Eighty-five subjects (age of 56.8 ± 15.3 years [mean ± standard deviation]) were recruited with a total of 17 colorectal cancer (20.0%) and 10 colorectal adenoma patients (11.8%). The sensitivity of M2-PK test in colorectal cancer detection was higher than gFOBT (100% vs. 64.7%). M2-PK test had a lower specificity when compared to gFOBT (72.5% vs. 88.2%) in colorectal cancer detection. The positive and negative predictive values were 47.2% and 100% for M2-PK test and 57.9% and 90.9% for gFOBT.
CONCLUSION: Fecal M2-PK Quick test has a high sensitivity for detection of colorectal cancer when compared to gFOBT, making it the potential choice for colorectal tumor screening biomarker in the future.
Methodology: The antimicrobial activity of synthesized 2MBI derivatives were evaluated against Gram positive and Gram negative bacterial species as well as fungal species by tube dilution technique whereas their anticancer activity was assessed against human colorectal carcinoma cell line (HCT116) by Sulforhodamine B (SRB) assay. They were also structurally characterized by IR, NMR, MS and elemental analyses.
Results discussion and conclusion: The antimicrobial activity findings revealed that compound N1 (MIC

= 1.27, 2.54, 1.27 µM), N8 (MIC

= 2.65 µM) exhibited significant antimicrobial effects against tested strains, i.e. Gram-positive, Gram-negative (bacterial) and fungal strains. The anticancer screening results demonstrated that compounds N9, N18 (IC50 = 5.85, 4.53 µM) were the most potent compounds against cancer cell line (HCT116) even more than 5-FU, the standard drug (IC50 = 9.99 µM).
Aims: To assess the OCT4 stemness factor in oral leukoplakia for its potential risk to malignant transformation.
Settings and Design: 20 cases of oral leukoplakia were obtained from archives at Oral Cancer Research & Coordinating center (OCRCC) Malaysia Subjects and Methods: 20 cases of oral leukoplakia were assessed by OCT4 immunohistochemically. Oral squamous cell carcinoma was used as a control.
Result: no expression of OCT 4 was observed in any cases of oral leukoplakia.
Conclusion: The molecular mechanisms of Oct4 regulation and in particular of its switch on and off in tissues depends upon its microenvironment, which makes it challenging in fundamental and applied research fields of regenerative medicine and cancer therapy. It's better that patients should undergo multiple biopsies for the early detection of malignant transformation with close follow-up during the first two to three years, a large amount of work remains to be done with multi-marker panel investigation, as cure rates have remained constant over three decades.
METHODS: A literature search of PubMed, ScienceDirect, and Scopus was carried out. The search strategy was restricted to human subjects and studies are published in English. Data on sensitivity and specificity were extracted and pooled. Heterogeneity was assumed at significance level of p < 0.10 and was tested by chi squared. Degree of heterogeneity was quantified using the I2 statistic, and values of less than 25% is considered as homogenous. All analyses were performed using the software Meta-Disc.
RESULTS: A total of eleven studies were suitable for data synthesis and analysis. Five studies were analyzed for the accuracy of genetic testing, the pooled estimate for sensitivity and specificity were 71% (95% CI: 66, 75%) and 95% (95% CI: 93, 97%) respectively. Another group of studies which had been evaluated for the accuracy of FOBT, the pooled sensitivity was 31% (95% CI: 25, 38%) while the pooled specificity was 87% (95% CI: 86, 89%).
CONCLUSIONS: FOBTs is recommended to use as population-based screening tools for colorectal cancer while genetic testing should be focusing on patients with moderate and high risk individuals.
METHODOLOGY: The study design was quasi-experimental. The interprofessional (IP) team implemented an educational module and analyzed the difference in awareness of young individuals toward the cancer cervix. A pretest and posttest written questionnaire, customized for both genders, was administered with the intervention of the educational module in between. The module consisted of a short educational presentation along with a group activity. A follow-up survey was also done after 2 months to check the attrition of awareness. The statistical analysis was done using MacNemar test using SPSS 12 IBM software and significance of differences were determined.
RESULTS: There was a significant improvement of knowledge and awareness on linkage between HPV and cervical cancer (P < 0.001). There was also significant change with regard to attitudes toward cervical cancer vaccination (P = 0.004). The knowledge of HPV linkage to the malignancy was maintained after 2 months of gap. The subjects also wished for more future awareness program.
CONCLUSIONS: There is improved awareness in the dental and foundation in science students, and this improved awareness will ensure favorable attitudes toward cervical cancer vaccines or will attend regular screening programs. Awareness program must be held at regular intervals at different locations to enhance the knowledge dissemination of this common yet preventable genital malignancy of females. The IP collaboration and practices will help in reducing the disease burden of the society in future.
