For the first time, electrospun polycaprolactone (PCL) 3D nanofibrous scaffold has been developed by an innovative and convenient approach (i.e., thermally induced nanofiber self‐agglomeration followed freeze drying), possesses interconnected hierarchically structured pores including macropores with sizes up to ≈300 μm. The novel PCL is soft elastic very high porosity of ≈96.4%, thus it morphologically/structurally similar natural extracellular matrix well suited for cell functions tissue...
Novel core−shell structured nanoassemblies are assembled by a β-cyclodextrin containing positively charged host polymer and hydrophobic guest polymer. The core of these types assemblies serves as nanocontainer to load release the drugs, while hydrophilic shell is able condense plasmid DNA achieve its transfection/expression in osteoblast cells. These may be used new generation multifunctional nanocarriers for simultaneous drug delivery gene therapy.
Carbapenem resistance in Acinetobacter spp. is an emerging problem China. We investigated the molecular epidemiology and carbapenemase genes of 221 nonrepetitive imipenem-resistant clinical isolates collected from 1999 to 2005 at 11 teaching hospitals Genotyping by pulsed-field gel electrophoresis (PFGE) found 15 PFGE patterns. Of these, one (clone P) was identified four Beijing another A) geographically disparate cities. Most exhibited high-level all beta-lactams were only susceptible...
The role of erythropoietin (Epo) and Epo/Epo receptor (EpoR) signaling pathways for production red blood cells are well established. However, little is known about Epo/EpoR in non-hematopoietic cells. Recently, we demonstrated that Epo activates JAK/STAT hematopoietic stem (HSCs), leading to the bone morphogenetic protein 2 (BMP2) formation also directly mesenchymal form osteoblasts vitro. In this study, investigated effects mTOR on Epo-mediated osteoblastogenesis osteoclastogenesis. We...
The purpose of this study was to determine the lineage progression human and murine very small embryonic-like (HuVSEL or MuVSEL) cells in vitro vivo. In vitro, HuVSEL MuVSEL differentiated into all three embryonic germ layers. produced robust mineralized tissue origin compared with controls calvarial defects. Immunohistochemistry demonstrated that gave rise neurons, adipocytes, chondrocytes, osteoblasts within were also able differentiate similar lineages. First round serial transplants...
Abstract Nuclear receptor peroxisome proliferator-activated receptor-γ (PPARγ) is an essential transcription factor for adipocyte differentiation. In mesenchymal stem cells, PPARγ has been assumed to play a negative role in osteoblastic differentiation, by working adipogenesis dependent manner, due the reciprocal relationship between osteoblast and However, direct of function not fully understood, part inadequate model systems. Here, we describe adenoviral-mediated knockout system which...
Utilizing biomimetic materials to potentiate endogenous cell growth or signaling is superior relying on exogenous cells signals for bone formation. Desferoxamine (DFO), which a hypoxia-mimetic agent that chelates iron (Fe3+), mimics hypoxia encourage healing. However, high cytotoxicity, off-target effects, and the short half-life of DFO have significantly impeded its further applications. We mitigated these side effects by locally immobilizing onto gelatin nanofibrous (GF) scaffold retained...
Abstract The advent of adaptive manufacturing techniques supports the vision cell‐instructive materials that mimic biological tissues. 3D jet writing, a modified electrospinning process reported herein, yields structures with unprecedented precision and resolution offering customizable pore geometries scalability to over tens centimeters. These scaffolds support expansion differentiation human mesenchymal stem cells in vitro. Implantation these constructs leads healing critical bone defects...

The acquisition of resistance to one antibiotic sometimes leads collateral sensitivity a second antibiotic. Here, we show that vancomycin in Enterococcus faecium is associated with remarkable increase susceptibility pleuromutilin antibiotics (such as lefamulin), which target the bacterial ribosome. trade-off between and pleuromutilins mediated by epistasis van gene cluster msrC, encoding an ABC-F protein protects ribosomes from targeting. In mouse models vancomycin-resistant E. colonization...
ABSTRACT The resistance mechanism of 49 Enterobacteriaceae isolates with decreased susceptibility to carbapenems collected from 2004 2008 at 16 teaching hospitals in China was investigated. Moderate- high-level carbapenem most more closely associated loss or expression both major porins combined production AmpC extended-spectrum β-lactamase enzymes, while KPC-2, IMP-4, and IMP-8 carbapenemase may lead a low moderate level China.
To demonstrate the pro-osteogenic effect of burn injury on heterotopic bone formation using a novel ossicle in vivo model.Heterotopic ossification (HO), or abnormal soft tissue, is troubling sequela and trauma injuries. The exact mechanism by which influences unknown. aim this study was to develop mouse model formation.
