Prostate cancer is one of the most prevalent malignancies among men. Although chemotherapy has been an effective therapeutic approach for treating metastatic prostate cancer, serious undesired side effects have hampered its wide application clinically. In this work, a pH-responsive LHRH-conjugated hydroxyethyl starch-doxorubicin (HES-DOX/LHRH) prodrug was facilely synthesized by conjugating oxidized HES (HES-CHO) with DOX and LHRH through an acid-sensitive Schiff base bond. The resulting prodrug spontaneously self-assembled into nanoscopic micelle with a radius of about 55 nm in an aqueous environment...

Ununited peripheral nerves represent attractive site for connectivity with neuroprostheses because of their predictable internal topography allows for precise sorting of motor and sensory signals. Also transplantation of bone marrow mesenchymal stem cells (BMSCs) is increasingly recognized as an effective method of restore the peripheral nervous system injury due to its neuron-directed differentiation potential. This study was to evaluate the in vivo performance of BMSCs-packed Poly(3,4-ethylenedioxythiophene) (PEDOT) scaffolds across a critical nerve conduction gap and examine the potential mechanism by which BMSCs-packed PEDOT scaffolds mediates peripheral nerve regeneration in rat model of recurrent laryngeal nerve (RLN) deletion...

In embryos of an invertebrate chordate, Ciona intestinalis, two transcription factors, Foxa.a and Zic-r.b, are required for specification of the brain and the notochord, which are derived from distinct cell lineages. In the brain lineage, Foxa.a and Zic-r.b are expressed with no temporal overlap. In the notochord lineage, Foxa.a and Zic-r.b are expressed simultaneously. In the present study, we found that the temporally non-overlapping expression of Foxa.a and Zic-r.b in the brain lineage was regulated by three repressors, Prdm1-r...

Human embryonic stem cell line WA01 was genetically modified using zinc-finger nucleases and the PiggyBac/transponson system to introduce a fluorescence reporter for VE-cadherin (VEC; tdTomato) and CD43 (eGFP). Phenotypic and functional assays for pluripotency revealed the modified hES cell reporter lines remained normal. When the cells were differentiated into hematoendothelial lineages, either by directed differentiation or direct reprogramming, flow cytometric and fluorescence microscopy showed that VEC+ endothelial cells express tdTomato and CD43+ hematopoietic progenitors express eGFP...

BACKGROUND: Granulocyte apheresis requires a sedimentation agent. Usually, hydroxyethyl starch (HES) is administered to donors for this purpose and, as granulocyte concentrate (GC) ingredient, also to patients. Authorities recently recommended suspending market authorizations for starch-containing products due to side effects. Therefore, we tested the efficacy of modified fluid gelatin (MFG, Gelafundin 4%) versus hetastarch (Hespan) for GC apheresis. STUDY DESIGN AND METHODS: This retrospective matched-pair analysis compared MFG- and hetastarch-derived GCs...

Osteosarcoma (OS) is a major cause of cancer-related mortality in children and young adults worldwide. Due to preexisting or acquired chemoresistance, the current standard neoadjuvant chemotherapy regimens show only moderate activity against OS. In the current study, we explored the potential anti-OS Cinobufagin in vitro and in vivo, and investigated its underlying mechanisms. The antitumor potential of Cinobufagin was assessed using cell viability assays, and cycle and apoptosis were determined. In a cell-based assay, the mRNA and protein expression of Notch-1, Hes-1, Hes-5 and Hey-1 were determined by quantitative polymerase chain reactions and western blotting...
