The effects of 10 mM putrescine (Put) treated by spraying on leaves on growth, chlorophyll content, photosynthetic gas-exchange characteristics, and chlorophyll fluorescence were investigated by growing cucumber plants (Cucumis sativus L. cv. ChangChun mici) using hydroponics with or without 65 mM NaCl as a salt stress. Salt stress caused the reduction of(More)
Conventional cytogenetic analysis is often hampered owing to the low mitotic index of multiple myeloma (MM) cells in bone marrow samples of MM. Interphase fluorescence in situ hybridization (I-FISH) analysis combined with magnetic-activated cell sorting (MACS) has substantially enhanced the sensitivity of cytogenetic analysis. Here, we used I-FISH to(More)
Previous studies have shown beneficial effects of mesenchymal stem cell (MSC) transplantation in central nervous system (CNS) injuries, including traumatic brain injury (TBI). Potential repair mechanisms involve transdifferentiation to replace damaged neural cells and production of growth factors by MSCs. However, few studies have simultaneously focused on(More)
Many studies have shown that microglia in the activated state may be neurotoxic. It has been proven that uncontrolled or over-activated microglia play an important role in many neurodegenerative disorders. Bone marrow-derived mesenchymal stem cells (BMSCs) have been shown in many animal models to have a therapeutic effect on neural damage. Such a(More)
Glioblastoma stem cells (GSCs) play an important role in the progression and recurrence of malignant glioblastoma because of their potential for self-renewal, multilineage differentiation and tumor initiation. A disintegrin and metalloproteinase 17 (ADAM17) is responsible for the proteolytic cleavage of Notch within its extracellular domain leading to the(More)
DNA methyltransferase (DNMT) and histone deacetylase are key enzymes mediating the epigenetic regulation of gene expression. DNA hypermethylation and/or histone deacetylation in promoter regions is often associated with downregulation or silencing of transcription. Epigenetic silencing of tumor suppressor genes plays an important role in malignant(More)
No confirmed risk factors are known to predict Richter syndrome (RS), and the value of clinical prognosticators conventionally applied to chronic lymphocytic leukemia (CLL) is not firmly established in this setting. The objective of this study was to present evidence for RS in Chinese patients with CLL and risk factors for CLL transformation to Richter(More)
Dendritic cells (DCs) are potent antigen-presenting cells (APCs) that are characterized by the ability to take up and process antigens and prime T cell responses. Mesenchymal stem cells (MSCs) are multipotent cells that have been shown to have immunomodulatory abilities, including inhibition of DC maturation and function in vivo and in vitro; however, the(More)
A unique ruthenium(II) complex, tris(4-methyl-2,2'-bipyridyl-4'-carboxaldehyde)Ru(II) hexafluorophosphate [Ru(CHO-bpy)(3)](PF(6))(2), has been designed and synthesized as a highly sensitive and selective luminescence probe for the recognition and detection of cysteine (Cys) and homocysteine (Hcy). The almost non-luminescent probe can rapidly react with Cys(More)
Multiple myeloma (MM) is characterized by a profound genomic instability of potential prognostic relevance. Loss of chromosome 13, observed in almost half of patients, negatively affects prognosis. MiR-15a, miR16-1 and miR-17-92 cluster, located on 13q, play important roles in the regulation of cell proliferation, differentiation and apoptosis. Therefore,(More)
