General description
L-Tyrosine is an important amino acid mainly used as a dietary supplement.
L-tyrosine, an aromatic amino acid, is used common dietary supplement that has a wide range of applications in food and pharmaceutical industry. It is a precursor for preparing industrially important compounds such as 3,4-dihydroxy-L-phenylalanine (L-DOPA), melanin and p-hydroxystyrene. L-tyrosine can be synthesized by different biotechnological methods which are ecofriendly.

Low-grade gliomas (LGGs) may harbor malignant foci, which are characterized by increased tumor cellularity and angiogenesis. We used diffusion-weighted MR imaging (apparent diffusion coefficient [ADC]) and PET with the amino acid O-(2-(18)F-fluorethyl)-L-tyrosine ((18)F-FET) to search for focal changes of diffusion

For the past decade, PET with (18)F-fluoro-ethyl-tyrosine ((18)F-FET) has been used in the evaluation of patients with primary brain tumors (PBTs), but so far series have reported only a limited number of patients. The purpose of this systematic review and

Photobiological H2 production is an attractive option for renewable solar fuels. Sulfur-deprived cells of Chlamydomonas reinhardtii have been shown to produce hydrogen with the highest efficiency among photobiological systems. We have investigated the photosynthetic reactions during sulfur deprivation and H2
