| fermentative production of thymidine by a metabolically engineered escherichia coli strain. | thymidine is an important precursor in the production of various antiviral drugs, including azidothymidine for the treatment of aids. since thymidine-containing nucleotides are synthesized only by the de novo pathway during dna synthesis, it is not easy to produce a large amount of thymidine biologically. in order to develop a host strain to produce thymidine, thymidine phosphorylase, thymidine kinase, and uridine phosphorylase genes were deleted from an escherichia coli bl21 strain to develop b ... | 2009 | 19251902 |
| the effect of hormone replacement treatment on thrombin-activatable fibrinolysis inhibitor activity levels in patients with hashimoto thyroiditis. | hypothyroid patients have increased risk of cardiovascular diseases, and several mechanisms have been considered responsible in these patients. although, a few studies demonstrated fibrinolytic system changes in hypothyroid patients, there is no study demonstrating tafi activity in hypothyroid hashimoto's thyroiditis patients. the aim of this study was to evaluate tafi activity status and the effect of l thyroxin hormone replacement treatment on fibrinolytic system in this patient group. | 2009 | 19252348 |

| rapid metabolic and newborn screening of thyroxine (t4) from dried blood spots by ms/ms. | thyroxin (t(4)) plays an important role in the regulation of the rate of metabolism of proteins, fats, and carbohydrates. congenital hypothyroidism, an inherited deficiency of thyroid hormones, is screened in newborns using a variety of methods that include total t(4) or thyroid stimulating hormone (tsh). some laboratories measure either total t(4) or tsh as a means of detecting infants with hypothyroidism with a subset that analyzes both total t(4) and tsh as a primary screen or a combination o ... | 2009 | 19254705 |
| development and evaluation of a structural model for sf1b helicase dda. | helicases are proteins that unwind double-stranded nucleic acids. dda helicase from bacteriophage t4 has served as an excellent model for understanding the molecular mechanism of this class of enzymes. study of the structure of dda may reveal why some helicases translocate in a 5' to 3' direction on dna, while others translocate in a 3' to 5' direction. attaining a structure of dda has proven difficult because the protein fails to readily form crystals and is too large for current nmr technologi ... | 2009 | 19256528 |
