[11C]-L-Methionine positron emission tomography in the management of children and young adults with brain tumors [PDF]

, 2009
Only a few Methyl-[11C]-l-methionine (MET) positron emission tomography (PET) studies have focused on children and young adults with brain neoplasm. Due to radiation exposure, long scan acquisition time, and the need for sedation in young children MET ...

Selective Crystallization of Racemic Polymorph via Native Enantiomer Inhibition: dl-Methionine

, 2023
Crystallization of chiral compounds is dictated by chiral recognition and molecular self-assembly in solution. However, their interplay remains elusive.

Perturbation of Methionine/S-adenosylmethionine Metabolism as a Novel Vulnerability in MLL Rearranged Leukemia

Cells, 2019
Leukemias bearing mixed lineage leukemia (MLL) rearrangement (MLL-R) resulting in expression of oncogenic MLL fusion proteins (MLL-FPs) represent an especially aggressive disease subtype with the worst overall prognoses and chemotherapeutic response. MLL-

An infant with an extremely rare cobalamin disorder: Methionine synthase deficiency and importance of early diagnosis and treatment

The Turkish Journal of Pediatrics, 2019
Functional methionine synthase deficiency can be separated into two classes, cobalamin (Cbl) deficiency type E (CblE) and type G (CblG), which are the result of mutations that affect methionine synthase reductase or methionine synthase, respectively ...

Methionine Dependence of Cancer

Biomolecules, 2020
Tumorigenesis is accompanied by the reprogramming of cellular metabolism. The shift from oxidative phosphorylation to predominantly glycolytic pathways to support rapid growth is well known and is often referred to as the Warburg effect.

Cysteine and Methionine Biosynthetic Enzymes Have Distinct Effects on Seed Nutritional Quality and on Molecular Phenotypes Associated With Accumulation of a Methionine-Rich Seed Storage Protein in Rice [PDF]

, 2020
Staple crops in human and livestock diets suffer from deficiencies in certain “essential” amino acids including methionine. With the goal of increasing methionine in rice seed, we generated a pair of “PushxPull” double transgenic lines, each containing a

Terahertz Spectroscopy and Density Functional Theory Calculations of dl-Norleucine and dl-Methionine

, 2018
We present terahertz (THz) measurements and density functional theory (DFT) calculations of two amino acid crystals: dl-norleucine and dl-methionine. Their molecular structures are very similar and therefore also their crystal structures.

Kinetics and mechanism of the oxidation of methionine by quinolinium chlorochromate [PDF]

Journal of the Serbian Chemical Society, 2005
The oxidation of methionine by quinolinium chlorochromate (QCC) has been studied, in the presence of chloroacetic acid, and in water-acetic acid mixtures of varying mole fractions. The reaction is first order with respect to methionine, QCC and acid. The

Broiler Responses to Reduced Protein and Energy Diets Supplemented With Lysine, Methionine and Threonine

The Journal of Poultry Science, 2012
This study was performed to evaluate the effect of supplementation of low crude protein (CP) corn-soybean meal diets which contained low ME levels with lysine (Lys), methionine (Met) and threonine (Thr) above that recommended by the National Research ...
