Báo cáo khóa học: Escherichia coli thioredoxin inhibition by cadmium Two mutually exclusive binding sites involving Cys32 and Asp26

Observations of thioredoxin inhibition by cadmium and of a positive role for thioredoxin in protection from Cd 2+ led us to investigate the thioredoxin–cadmium interaction properties.We used calorimetric and spectroscopicmethods at different pHvalues to explore the relative contribution of putative binding residues (Cys32, Cys35, Trp28, Trp31 and Asp26) within or near the active site. At pH 8 or 7.5 two binding sites were identified by isothermal titration calorimetry with affinity constants of 10·10 6 M )1 and 1·10 6 M )1 . ...

Báo cáo khoa học: Transcription of mammalian cytochrome c oxidase subunit IV-2 is controlled by a novel conserved oxygen responsive element

Subunit 4 of cytochromecoxidase (CcO) is a nuclear-encoded regulatory subunit of the terminal complex of the mitochondrial electron transport chain. We have recently discovered an isoform of CcO 4 (CcO4-2) which is specific to lung and trachea, and is induced after birth. The role of CcO as the major cellular oxygen consumer, and the lung-specific expression of CcO4-2, led us to investigate CcO4-2gene regulation.

Đề tài " Elliptic units for real quadratic fields "

Elliptic units, which are obtained by evaluating modular units at quadratic imaginary arguments of the Poincar´e upper half-plane, provide us with a rich source of arithmetic questions and insights. They allow the analytic construction of abelian extensions of imaginary quadratic fields, encode special values of zeta functions through the Kronecker limit formula, and are a prototype for Stark’s conjectural construction of units in abelian extensions of number fields.

Báo cáo nghiên cứu nông nghiệp " Improvement of export and domestic markets for Vietnamese fruit through improved post-harvest and supply chain management "

The fruit industry in Vietnam has a great potential and plays an important role in agricultural production. In 2003, Vietnam exported US$43 million of high value fruit to high-income countries and imported US$14 million of fruit and vegetables. Vietnam is experiencing difficulties in competing with other Asian nations in export markets and its own domestic market, especially with China and Thailand. This suggests that Vietnam’s horticultural industries require substantial development to be globally competitive. Vietnamese consumers are demanding safer and higher quality fruit.
