among the synthetic polymers, poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (phbv) microbial polyester is one of the biocompatible and biodegradable copolymers in the nanomedicine scope. phbv has key points and suitable properties to support cellular adhesion, proliferation and differentiation of nanofibers. nanofibers are noticeably employed in order to enhance the performance of biomaterials,...

Magnesium (Mg) and its alloys are very promising degradable, osteoconductive osteopromotive materials to be used as regenerative treatment for critical-sized bone defects. Under load-bearing conditions, Mg must display sufficient morphological mechanical resemblance the native they meant replace provide adequate support enable initial bridging. In this study, unique highly open-porous Mg-based ...

BACKGROUND A promising approach to improve the performance of neural implants consists of adding nanomaterials, such as nanowires, to the surface of the implant. Nanostructured interfaces could improve the integration and communication stability, partly through the reduction of the cell-to-electrode distance. However, the safety issues of implanted nanowires in the brain need to be evaluated an...

Background: One of the main challenges with conventional scaffold fabrication methods is the inability to control scaffold architecture. Recently, scaffolds with controlled shape and architecture have been fabricated using 3D-printing. Herein, we aimed to determine whether the much tighter control of microstructure of 3DP PLGA/β-TCP scaffolds is more effective in promoting osteogenesis than por...

Intercropping legume with cereal is an extensively applied planting pattern in crop cultivation. However, forage potential and the degradability of harvested mixtures from intercropping system remain unclear. To investigate the feasibility of applying an intercropping system as a forage supply source to ruminants, two consecutive experiments (experiments 1 and 2) involving a field cultivation t...

Nanofibrous scaffolds produced by electrospinning have attracted much attention, recently. Aligned and random nanofibrous scaffolds of poly (vinyl alcohol) (PVA), poly (ε-caprolactone) (PCL) and nanohydroxyapatite  (nHA) were fabricated by electrospinning method in this study. The composite nanofibrous scaffolds were subjected to detailed analysis. Morphological investigations revealed that the...

background: the aim of this study was to fabricate the poly caprolactone (pcl) aligned nanofiber scaffold and to evaluate the survival, adhesion, proliferation, and differentiation of rat hair follicle stem cells (hfsc) in the graft material using electrospun pcl nanofiber scaffold for tissue engineering applications. methods: the bulge region of rat whisker was isolated and cultured in dmem: n...

We exhibit a possible road towards a strong converse for the quantum capacity of degradable channels. In particular, we show that all degradable channels obey what we call a “pretty strong” converse: When the code rate increases above the quantum capacity, the fidelity makes a discontinuous jump from 1 to at most 1 √ 2 , asymptotically. A similar result can be shown for the private (classical) ...

Degradable and cell-compatible hydrogels can be designed to mimic the physical and biochemical characteristics of native extracellular matrices and provide tunability of degradation rates and related properties under physiological conditions. Hence, such hydrogels are finding widespread application in many bioengineering fields, including controlled bioactive molecule delivery, cell encapsulati...
