Introduction: There is an increasing demand for additional techniques to diagnose and treat cancer including CRC or colorectal cancer effectively. Utilizing antibodies as biomarker could contribute to accurate diagnosis of cancer due to its high specificity and sensitivity. One of the etiologies of CRC progression was proposed as the alterations of hexosamine biosynthetic pathway which could subsequently influence the rate-limiting enzyme, glutamine-fructose-6-phosphate aminotransferase (GFAT1). These increased enzymatic activities resulted in an elevation of glucose uptake that provides nutrients facilitating the progression of cancer cells. Therefore, we attempted to determine the potential of GFAT1 as the biomarker for CRC by correlating its expression with clinicopathological features of the patients. Methods: A total of 132 10% formalin-fixed paraffin embedded tissue were retrieved. Immunohistochemistry (IHC) was performed on the tissue sections and digital images were subsequently acquired. All the images were automatedly analyzed using IHC Profiler. GFAT1 immunoreactivity in colorectal tissues was calculated using an adapted H-score formula. Clinicopathological features of the patients were statistically correlated with the status of GFAT1. Results: Colorectal adenocarcinoma tissues had the significantly highest GFAT1 H-scores with the mean of 103.18 compared to adenoma and non-tumor tissues. There have been no significant associations between clinicopathological characteristics of the patients and the status of GFAT1 except for tumor size. Conclusion: Immunoreactivity of GFAT1 was significantly different between non-tumorous tissues and adenocarcinoma as well as between adenoma and adenocarcinoma tissues. GFAT1 could serve as one of the prognostic biomarkers or useful targets.1 [ABSTRACT FROM AUTHOR]

Introduction: Children in pre-schools are at high risk of getting infections due to overcrowding, minimal awareness of basic hygiene and lack of immunity against microorganisms. Hand hygiene practice should be started at home where parents set good example, followed by formal education in pre- schools, primary and secondary school. This study aimed to develop a comprehensive program on hand hygiene practice in pre-schools. This paper presents the developmental aspects of the program material and the results of its evaluation process in a selected pre-school. Methods: Stage of development involved preparation of song, lyric, video clip, infographic and tablet application. The module was introduced during an intervention day called 'Healthy Hands' day. The acceptance of the module was evaluated before and after the intervention day. Evaluation was done by assessing pre-school children by faceto- face interview about knowledge on hand hygiene techniques and routine, such as before or after certain activities. Results: We managed to compose a song in three languages (Malay, English & Arabic), produced a video clip, an infographic and tablet application. A total of 227 children participated. Post intervention evaluation showed significant (p<0.001) increase of knowledge for eight out of eleven handwashing steps. The knowledge on hand hygiene routine i.e. after toilet, after playing outdoor, after sneezing and after playing with pet was also increased significantly. Conclusion: This comprehensive knowledge transfer program significantly improved the children's hand hygiene techniques and routine and is recommended to be integrated into pre-school curriculum.
