Islam  Abstract Overexpression of epithelial cell adhesion molecule (EpCAM) has been associated with chemotherapeutic resistance, leads to aggressive tumor behavior, and results in an adverse clinical outcome. The molecular mechanism by which EpCAM enrichmen

Widespread expression of Sonic hedgehog (Shh) and Nrf2 in patients treated with cisplatin predicts outcome in resected tumors and are potential therapeutic targets for HPV-negative head and neck cancer

Islam Abstract Background: Sonic hedgehog (Shh) and Nrf2 play a critical role in chemotherapeutic  resistance. These two genes have been found to be dysregulated in head and neck squamous cell carcinomas (HNSCC). The purpose of this study was to analyze the expression, function and clinical prognostic relationship of Shh and Nrf2 in HNSCC in the

Proximal principle of food Definition: are defined as the number of nutrient present in the diet to maintain optimal growth of an organism. Nutrition: Nutrition is a science that relates food with health. Nutrient: It is an essential chemical substances present in the diet required for optimal growth and maintenance of the health of an organism. Fiber: Fibers are a non-digestive, non-caloric, fraction of carbohydrate present in the diet. Example: Cellulose, pectin, agar, etc. Trace element: Trace elements are micronutrients required in diet < 100mirogram /day. Example: 3C: Copper, Cobalt, Chromium 2M: Manganese, Molybdenum 2I: Iodine, Iron Selenium, Fluoride, Zinc. About CHO 1.    Total energy in Kcal/day is 50-65% CHO 2.    Complex: starch variety 3.    Ready sugar must be avoided. 4.    Spares fat and protein 5.    One fraction of CHO should be fiber. About Protein 1.    Daily requirement: Adult: 1g/kgbw.Baby: 1.5-2g/kgbw. 2.
