Heat shock protein (Hsp) 70 is an activator of the Hsp104 motor
Heat shock protein (Hsp) 104 is a ring-forming, protein-remodeling machine that harnesses the energy of ATP binding and hydrolysis to drive protein disaggregation. Although Hsp104 is an activeExpand

Akt Is a Key Modulator of Endothelial Progenitor Cell Trafficking in Ischemic Muscle
Trafficking of transplanted endothelial progenitor cells (EPCs) to ischemic tissue is enhanced by stromal‐derived factor 1 (SDF‐1) and vascular endothelial growth factor (VEGF). However, it has notExpand

Involvement of E-selectin in recruitment of endothelial progenitor cells and angiogenesis in ischemic muscle.
E-selectin plays critical roles in tethering leukocytes to endothelial cells (ECs). We studied the role of E-selectin in endothelial progenitor cell (EPC) homing and vasculogenesis. After ischemia,Expand

Associations of organochlorine pesticides and polychlorinated biphenyls in visceral vs. subcutaneous adipose tissue with type 2 diabetes and insulin resistance.
Background exposure to organochlorine (OC) pesticides and polychlorinated biphenyls (PCBs) has been linked to type 2 diabetes. As OC pesticides and PCBs mainly accumulate in adipose tissue and thereExpand

Loss of beta-cells with fibrotic islet destruction in type 2 diabetes mellitus.
Recent morphologic analyses of human pancreases strongly suggest that a decreased beta-cell mass is observed from the early stages of diabetes and is caused by accelerated apoptosis of theExpand

Chorea-ballism associated with nonketotic hyperglycaemia or diabetic ketoacidosis: characteristics of 25 patients in Korea.
Chorea-ballism is a rare form of movement disorder complicated by severe hyperglycaemia and in association with a contralateral basal ganglia lesion. We analysed the clinical characteristics of 25Expand
