Metreleptin Supplementation for Improving Lipid and Glycemic Profiles in Acquired Diabetes Lipodystrophy: A Case Report.

Most childhood cancer survivors who undergo hematopoietic stem cell transplantation subsequently develop impaired glucose tolerance and hypertriglyceridemia. These conditions are presumably associated with total-body irradiation-related acquired lipodystrophy and may lead to cardiovascular disease. Metreleptin (recombinant leptin) may help improve the lipoprotein profile, insulin sensitivity, and quality of life of patients with total-body irradiation-related lipodystrophy.

Topochemical synthesis and catalysis of metal nanoparticles exposed on crystalline cellulose nanofibers.

Topochemical synthesis of gold nanoparticles (AuNPs) was achieved on crystalline cellulose single nanofibers (CSNFs), which were tailored from native cellulose. Exposed AuNPs@CSNFs composite exhibited an excellent catalytic efficiency: the turnover frequency of the AuNPs@CSNFs was up to 840 times that of conventional polymer-supported AuNPs, for a model aqueous reduction reaction. Our novel strategy provides a promising solution to realize efficient use of limited noble metals using natural bioresources.
