Folate status and health: challenges and opportunities.
Each year approximately 2400 pregnancies develop folic acid-preventable spina bifida and anencephaly in Europe. Currently, 70% of all affected pregnancies are terminated after prenatal diagnosis. The prevalence of neural tube defects (NTDs) has been significantly lowered in more than 70 countries worldwide by applying fortification with folic acid. Periconceptional supplementation of folic acid...
متن کاملChicken genome: current status and future opportunities.
The chicken genome sequence is important for several reasons. First, the chicken shared a common ancestor with mammals approximately 310 million years ago (Mya) at a phylogenetic distance not previously covered by other genome sequences. It therefore fills a gap in our knowledge and understanding of the evolution and conservation of genes, regulatory sequences, genomes, and karyotypes. The chic...
متن کاملPlant Tissue Culture: Current Status and Opportunities
Tissue culture is the in vitro aseptic culture of cells, tissues, organs or whole plant under controlled nutritional and environmental conditions [1] often to produce the clones of plants. The resultant clones are true-to type of the selected genotype. The controlled conditions provide the culture an environment conducive for their growth and multiplication. These conditions include proper supp...
متن کاملSmart Cards: Status, Issues, and US Adoption
The smart card has a microprocessor or a memory chip embedded in a plastic card. It has been in wide use in Europe and Japan for payment, entry into buildings and computer systems, and storage and access of special types of information. In the US, despite efforts by the credit card industry, the smart card has not been nearly as widely adopted as in Europe and Japan. In this article, we will re...
متن کاملMaglev Train Propulsion System
This project was an experiment on the feasibility of superconductorbased maglev trains. Two classmates, Kyle Tessier-Lavigne and Michael Stern, and I worked in conjunction to produce a magnetic track, levitating train car, and propulsion system. This paper focuses on my part of the project, the propulsion system. The propulsion system is similar to a linear motor, with a row of solenoids attrac...
