The First Compound Heterozygosity for Two Different α-Thalassemia Determinants Causes Hb Bart's Hydrops Fetalis in a Chinese Family.

In southern China, α-thalassemia is the most prevalent hereditary monogenic disorder, and deletion variants are the predominant form. Conventional thalassemia diagnosis techniques are numerous, however they are all limited in their ability to detect rare deletions. Here, we discuss a family who sought genetic counseling during their fourth pregnancy after experiencing Hb Bart's hydrops fetalis in two of their previous pregnancies.

The Facile Synthesis of a Re-Complex Heterogeneous Catalysis System for Enhancing CO Photoreduction Activity.

-Re(2,2'-bipyridine)(CO)Cl] (denoted as ReCC) is an efficient molecule-catalyst with high selectivity in the photoreduction of CO to CO in a homogeneous system. However, the two major drawbacks of Re(I) complexes in the homogeneous system, easy degradation and difficult separation, seriously hinder its development in the field of industrial applications. In this paper, we designed and prepared two different Re-complex fixation systems (denoted as ReCC@TiO-5 wt% and ReCC-TiO-5 wt%) based on TiO gel via the sensitization method and sol-gel method, respectively.
