Zidovudine was the first agent to be used to prevent the transmission of HIV from a pregnant woman to her child. It was given to the mother at 14 to 34 weeks gestation and to the child for the first 6 weeks of life. Current combination therapies employ zidovudine with another NRTI and a protease inhibitor.

The short lifetime of present PEM fuel cells will in general terms increase life-cycle impacts relative to technologies with a long operational life. Current cells degrade significantly after less than 2000 h of operation (Ahn et al.. 

Metabolic Roles. Ascorbic acid is an electron donor required for a variety of oxidative processes. It is readily regenerated by glutathione, NAD, and NADP and thus has a long biological half-life. Currently, there are eight known human enzymes that require ascorbic acid, and they are listed in Table 8.5. The precise metabolic roles have not been completely elucidated, but it appears that in the met-alloenzymes, ascorbate reduces the active metal site. In addition to these specific enzymes, ascorbic acid seems to function as a free-radical scavenger in the aqueous phase of plasma and cells. 

As polysaccharide vaccines were shown to elicit only limited protection in infants and young children, conjugated polysaccharide vaccines were developed to provide a more potent and sustained immune response [2]. Many of these traditional vaccines target childhood diseases, and are used in combinations for pediatric applications in order to reduce the number of injections during the first years of life. Currently, vaccine combinations can prevent against between three to six different diseases, such as the measles-mumps-rubella (MMR) vaccine or the diphtheria-tetanus-pertussis combination, which may be administered together with Haemophilus influenzae, hepatitis B, or poliovirus vac-... 

The quality of life currently enjoyed by a large proportion of the world s population is ever more dependent upon the multitude of various materials we are able to produce and use. Fabrics, plastics, prepared and preserved foodstuffs and pharmaceuticals exemplify broad categories of products that are used everyday by millions. All these commodities are the result of manufacturing and conversion processes that are controlled for quality, consistency and economic viability. 

There is a huge amount energy in our environment. And the nature has its own laws of the transformation between the solar, thermal and vibration energy, and electricity, the most universal energy form used in daily life. Currently, only a part of the photovoltaic effect, thermoelectric effect, piezoelectric effect, and triboelectric effect has been investigated, and more efforts are required to carefully understand these effects to further optimize the device structure and enhance the device performance.

The automotive industry has also directed efforts toward improving the recyclahUity of automotive plastics by change in automobile design. Efforts include designing components for ease of disassembly, as well as efforts to minimize the use of different resins and to ensure that all resins in a component are compatible with one another. One of the reasons for these changes, in addition to voluntary actions by manufacturers, is requirements in Europe that mandate that the auto industry provide a system for collection and recycling of vehicles at the end of their life. Currently, 74 to 80 percent of the weight of a typical vehicle is reused or recycled the End of Life Vehicle Directive requires that this amount be increased to 80 percent by 2006 and 85 percent by 2015. Furthermore, vehicles must increase their use of recycled materials. ... 

No moving parts and promise of long life - Because a fuel cell does not have any moving parts, it may be expected to exhibit a long life. Current fuel cell technology may reach the lifetime acceptable for automotive applications (3000-5000 hours), but their durability must be improved by an order of magnitude for use in stationary power generation (where the requirement is >40,000-80,000 hours). 

Inflammatory bowel disease (Crohn s disease and ulcerative colitis) occurs among all age groups but has peaks of incidence in the second and fourth decade of life. Currently, corticosteroid therapy is the most effective treatment for moderate to severe cases of IBD. Ocular pathology in the setting of IBD may be related to inflammation of the gastrointestinal tract or secondary to corticosteroid treatment. The two major ocular side effects of systemic corticosteroid therapy are posterior subcapsular cataract (PSC) and raised intraocular pressure (lOP). Recently, we reported that PSC was detected in 12 of 58 (20.7%) corticosteroid-treated pediatric IBD patients and that 21 patients of the same population (36.2%) had raised lOP. Because pediatric IBD patients continue corticosteroid therapy into adulthood, we analyzed the prevalence of PSC and raised lOP in a series of adult IBD patients. 

Currently, tomatoes, blueberries, strawberries, and mushrooms are being irradiated to allow them to be harvested when completely ripe and extend their shelf life (see Figure 16.3). The FDA has also approved the irradiation of pork, poultry, and beef in order to decrease potential infections and to extend shelf life. Currently, irradiated vegetable and meat products are available in retail markets in more than 40 countries. In the United States, irradiated foods such...
