  • Soybean is the most important oilseed and livestock feed crop in the world. These dual uses are attributed to the crop's high protein content (nearly 40% of seed weight) and oil content (approximately 20%); characteristics that are not rivaled by any other agronomic crop. Across the 10-year period from 2001 to 2010, world soybean production increased from 168 to 258 million metric tons (54% increase).

  • Efficacy of SNS in Different Disease States Efficacy studies have shown that malnourished patients undergoing major thoracoabdominal surgery benefit from SNS. Critical illness requiring ICU care including major burns, major trauma, severe sepsis, closed head injury, and severe pancreatitis [positive CT scan and Acute Physiology and Chronic Health Evaluation II (APACHE II) 10] all benefit by early SNS, as indicated by reduced mortality and morbidity. In critical illness, initiation of SNS within 24 h of injury or ICU admission is associated with a ~50% reduction in mortality.

  • Disease-Specific Nutritional Support SNS is basically a support therapy and is primary therapy only for the treatment or prevention of malnutrition. Certain conditions require modification of nutritional support because of organ or system impairment. For instance, in nitrogen accumulation disorders, protein intake may need to be reduced. However, in renal disease, except for brief periods of several days, protein intakes should approach requirement levels of at least 0.8 g/kg or higher up to 1.2 g/kg as long as the blood urea nitrogen does not exceed 100 mg/dL.

  • Protein Catabolism The rate of endogenous protein breakdown (catabolism) to supply energy needs normally falls during uncomplicated energy deprivation. After about 10 days of total starvation, the unstressed individual loses about 12–18 g/d protein (equivalent to approximately 2 oz of muscle tissue or 2–3 g of nitrogen).

  • A plant nutrient is a chemical element that is essential for plant growth and reproduction. Essential element is a term often used to identify a plant nutrient. The term nutrient implies essentiality, so it is redundant to call these elements essential nutrients. Commonly, for an element to be a nutrient, it must fit certain criteria. The principal criterion is that the element must be required for a plant to complete its life cycle. The second criterion is that no other element substitutes fully for the element being considered as a nutrient.

  • “Have you thanked a green plant today?” reads a popular bumper sticker. Indeed, we should thank green plants for providing the food we eat, fiber for the clothing we wear, wood for building our houses, and the oxygen we breathe. Without plants, humans and other animals simply could not exist. Psychologists tell us that plants also provide a sense of well-being and peace of mind, which is why we preserve forested parks in our cities, surround our homes with gardens, and install plants and flowers in our homes and workplaces.
