O Parenteral nutrition (PN), also called total parenteral nutrition (TPN), is the intravenous administration of fluids, macronutrients, electrolytes, vitamins, and trace elements for the purpose of weight maintenance or gain, to preserve or replete lean body mass and visceral proteins, and to support anabolism and nitrogen balance when the oral/enteral route is not feasible or adequate. 

Electrolytes, vitamins, and trace elements are essential for numerous biochemical and metabolic functions and should be added to PN daily unless otherwise not indicated. 

PN should provide a balanced nutritional intake, including macronutrients, micronutrients, and fluid. Macronutrients, including amino acids, dextrose, and intravenous lipid emulsions, are important sources of structural and energy-yielding substrates. A balanced PN formulation includes 10% to 20% of total daily calories from amino acids, 50% to 60% of total daily calories from dextrose, and 20% to 30% of total daily calories from intravenous lipid emulsion. Micronutrients, including electrolytes, vitamins, and trace elements, are required to support essential biochemical reactions. Parenteral... 

The medium for enzyme production was completely synthetic and limited in carbon to prevent excessive growth of mycelia. It contained glucose 2 g/l plus ammonia nitrogen, vitamins and trace elements according to Leisola et al.(ii). The 100 1 inoculum was transferred into 8001 of medium in a 10001 bioreactor equipped with 12 rrfi of nylon wool sheets supported by steel wire screen (Figure 1). The medium was continuously stirred with the impeller (100-200rpm) and saturated with pure oxygen. The temperature was maintained at 37°C.

In the cell fermentation stage of the process, calluses are propagated in a wholly aqueous medium in large fermenters under controlled conditions at ambient temperature and pressure. The feedstock for cell growth consists of renewable nutrients, sugars, amino acids, vitamins, and trace elements.

Nonbacterial milk components and components produced from milk fermentation may also contribute to the immunostimulatory activity of yogurt. Peptides and free fatty acids generated by fermentation have been shown to enhance the immune response. Milk components such as whey protein, calcium, and certain vitamin and trace elements also can influence the immune system. 

During the course of the symposium, several dietary factors that can influence xenobiotic metabolism were discussed in detail. Here we will attempt t summarize in the broadest terms how various classic nutrient groups might exert an influence on xenobiotic metabolism. For convenience, the dietary groups have been broken into carbohydrates, lipids, proteins, water-soluble vitamins, fat-soluble vitamins and trace elements. It is difficult to take any one group individually, and it must be kept in mind that the interactions are continuous and extremely complicated. 

This patent describes how a Jerusalem artichoke tea is prepared from sliced, dried, and pulverized tubers, which are cured, packed into bags, and radiated with ultraviolet light. The product has high levels of cellulose, vitamins, and trace elements, low levels of fat, and a range of potential health benefits. 

In the context of dmg delivery, certain cell surface receptor and ion-channel families are particularly appealing as dmg delivery targets. Well-characterized examples include the lectin-like receptor gene family as receptors for glycosylated molecules, as well as vitamin- and trace element-uptake systems such as the transferrin-receptor.

Adequate supplies of vitamins and trace elements are extremely critical in maintaining the health and development of humans. These nutrients occupy the attention of those concerned with the physical well being of a public made increasingly aware of the need for the quality and the quantity of their dietary intake. The general principle regarding assessment of nutritional status is to determine the extent to which the metabohc demand for nutrients has been or is currently being met by the supply. In clinical practice, this requires balancing supply and demand. 

The measurement of vitamin and trace element levels is frequently helpful in nutritional assessment. The relative value of such tests is increased by the fact that clinical assessment of their status is often poor. 

Although requirements for vitamins and trace elements are known in health (Table 30-1), the effects of illness on these requirements are poorly understood and quantified. However, it is now apparent that as an individual develops progressively more severe depletion in vitamin or trace element status, the person passes through a series of stages with biochemical or physiological consequences. The metabolic or physiological penalty of such suboptimal nutritional status is usually not clear, but the assumption remains that the suboptimal metabolism is likely to have detrimental effects (e.g., subclinical deficiency of folic acid is associated with an increase in serum homocysteine concentration, which is an independent risk factor for coronary artery disease—see Chapter 26). Similarly, subclinical deficiency of chromium may be associated with impaired glucose tolerance in certain types of diabetes. 

In an attempt to assess the functional adequacy of vitamins and trace elements involved in antioxidant pathways, products of oxidative metabolism can be measured. Those frequently used are malondialdehyde or F2 isoprostanes, both of which give an indication of oxidation of polyunsaturated fatty acids within cells. Increasing the provision of individual antioxidants or cocktails of vitamins and trace elements can lead to a reduction in production of these metabolites that can be measured in serum or urine. Such tests have not yet reached widespread application primarily because the interpretation of results is difficult. Also, knowledge of the appropriate amount of oxidative activity that is linked to particular outcomes has not yet been identified. This is especially hnportant since there have been few clinical studies demonstrating benefit from provision of increased amounts of antioxidants. ... 

Concentrations of vitamins and trace elements are measured most often in plasma or serum this provides a reliable index of status for only a few of them (e.g., vitamin B52 or vitamin D). For others (e.g., folate or selenium), their concentrations only may reflect the adequacy of recent intake. An excessive provision of elements such as manganese and chromium may also be detected by high serum concentrations. ...
