Genistein is one of the most studied isoflavonoids with potential antitumor efficacy, but its poor water solubility limits its clinical application. Nanoparticles (NPs), especially biodegradable NPs, entrapping hydrophobic drugs have promising applications to improve the water solubility of hydrophobic drugs. In this work, TPGS-b-PCL copolymer was synthesized from ε-caprolactone initiated by d-...

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...

The posterior cruciate ligament (PCL) is the largest and strongest ligament in the human knee, and the primary posterior stabilizer. Recent anatomy and biomechanical studies have provided an improved understanding of PCL function. PCL injuries are typically combined with other ligamentous, meniscal and chondral injuries. Stress radiography has become an important and validated objective measure...

The potential of constructs comprising induced pluripotent stem (iPS) cells and biopolymers can be high for neurological surgery practice, if the systematic activity of neuronal regeneration is clarified. This study shows a guided differentiation of iPS cells toward neurons in neuron growth factor (NGF)-grafted poly(ε-caprolactone) (PCL)-poly(β-hydroxybutyrate) (PHB) scaffolds. The porosity of ...

Small diameter arterial bypass grafts are considered as unmet clinical need since the current grafts have poor patency of 25% within 5 years. We have developed a 3D scaffold manufactured from natural and synthetic biodegradable polymers, poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and poly(𝜀-caprolactone) (PCL), respectively. Further to improve the biophysical properties as well as endo...

BACKGROUND The posterior cruciate ligament (PCL) plays an important role in maintaining physiological kinematics and function of the knee joint. To date mainly in-vitro models or combined magnetic resonance and fluoroscopic systems have been used for quantifying the importance of the PCL. We hypothesized, that both tibiofemoral and patellofemoral kinematic patterns are changed in PCL-deficient ...

Drug-eluting vascular prostheses represent a new direction in vascular surgery to reduce early thrombosis and late intimal hyperplasia for small calibre grafts. Subcutaneous implantation in rats is a rapid and cost-effective screening model to assess the drug-elution effect and could, to some extent, be useful to forecast results for vascular prostheses. We compared biological and histological ...

Background: Through combining two synthetic and natural polymers, scaffolds can be developed for tissue engineering and regenerative medicine purposes. Methods: In this work, carboxymethyl chitosan (CMC; 20%) was grafted to Polycaprolactone (PCL) nanofibers using the cold atmospheric plasma of helium. The PCL scaffolds were exposed to CAP, and functional groups were developed on the PCL surface...

Researchers see algae as a promising tool to discover both efficient and safe agents for pain therapy. We evaluated the antinociceptive and anti-inflammatory activities of lectin from the marine alga Pterocladiella capillacea lectin (PcL). PcL was purified and tested in classical models of nociception and inflammation. Male Swiss mice received PcL 30 min prior to receiving 0.8% acetic acid (10 ...

J Bone Joint Surg [Br] 2007;89-B:766-71. Received 16 October 2006; Accepted after revision 22 February 2007 Our aims were to map the tibial footprint of the posterior cruciate ligament (PCL) using MRI in patients undergoing PCL-preserving total knee replacement, and to document the disruption of this footprint as a result of the tibial cut. In 26 consecutive patients plain radiography and MRI o...
