Nanoparticles (NPs) are attractive materials owing to their physical and electrochemical properties, which make them extremely useful in diagnostic applications. Photon upconversion is the phenomenon where high-energy photons are emitted upon excitation of low-energy photons. Nucleic acids detection based on upconversion nanoparticles (UCNPs), which display a high signal-to-noise ratio and no p...

vitamin k is required for the hepatic production of blood coagulation factors ii, vii, ix and x. the term vitamin k refers to a variety of fat-soluble 2-methyl-1, 4-naphthoquinone derivatives. vitamin k1 (phylloquinone) occurs in green plants, while vitamin k2 (menaquinone) is synthesized by microbial in the gut. the recommended dose of vitamin k in neonates is 1 mg intramuscularly. for infants...

This trial tested whether rumen-protected Lys (RPL) supplementation would improve the nutritive value of rumen-undegradable protein (RUP) from corn protein. Thirty-two lactating Holstein cows were blocked by days in milk and parity into 8 squares 4 each replicated × Latin squares. Treatments provided all supplemental crude from: (1) soy (67% expeller soybean meal plus 33% solvent meal); (2) a b...

vitamin b12 (cobalamin) is an essential coenzyme for nucleic acid synthesis. animal protein is the major dietary source of vitamin b12. deficiency of vitamin b12 leads to megaloblastic anemia, degeneration of the brain, spinal cord, peripheral nerves, and abnormalities of epithelial tissues. two factors are necessary for the cure of megaloblastic anemia: one in food (extrinsic factor) and one i...
