BACKGROUND Research conducted with forensic psychiatric patients found moderate correlations between violence in institutions and psychopathy. It is unclear though, whether the PCL-R is an accurate instrument for predicting aggressive behavior in prisons. Results seem to indicate that the instrument is better suited for predicting verbal rather than physical aggression of prison inmates. METH...

Asymmetric telechelic α-hydroxyl-ω-(carboxylic acid)-poly(ε-caprolactone) (HA-PCL), α-hydroxyl-ω-(benzylic ester)-poly(ε-caprolactone) (HBz-PCL) and an asymmetric telechelic copolymer α-hydroxyl-ω-(carboxylic acid)-poly(ε-caprolactone-co-γbutyrolactone) (HA-PCB) were synthesized by ring-opening polymerization of εcaprolactone (CL). CL and CL/γ-butyrolactone mixture were used to obtain homopolym...

For successful bone tissue engineering, a scaffold needs to be osteoconductive, porous, and biodegradable, thus able to support attachment and proliferation of bone cells and guide bone formation. Recently, hydroxyapatites (HA), a major inorganic component of natural bone, and biodegrade polymers have drawn much attention as bone scaffolds. The present study was designed to investigate whether ...

BACKGROUND Lesser metatarsophalangeal joint (MTPJ) instability is a common complaint. The role each of the collateral structures play in maintaining joint stability is unknown. METHODS Twenty-six fresh-frozen cadaver lesser MTPJ's were tested for instability with the amount of force necessary to translate the joint 3 mm dorsally. Specimens were tested with 1) intact collateral ligaments, 2) t...

For most tissue engineering applications, surface modification and sterilization of polymers are critical aspects determining the implant success. The first part of this study is thus dedicated to modifying polycaprolactone (PCL) surfaces via plasma treatment using a medium pressure dielectric barrier discharge, while the second part focuses on the sterilization of plasma-modified PCL. Chemical...

BACKGROUND Long-term patency of conventional synthetic grafts is unsatisfactory below a 6-mm internal diameter. Poly(epsilon-caprolactone) (PCL) is a promising biodegradable polymer with a longer degradation time. We aimed to evaluate in vivo healing and degradation characteristics of small-diameter vascular grafts made of PCL nanofibers compared with expanded polytetrafluoroethylene (ePTFE) gr...

Physicians may be unfamiliar with posterior cruciate ligament (PCL) injuries because the PCL is injured far less frequently than the anterior cruciate ligament and the injury may have a subtle presentation. Contact sport athletes and persons involved in motor vehicle collisions often are affected. PCL injuries frequently occur in conjunction with damage to other capsuloligamentous structures of...

The paper describes a language called PCL, which has been designed to model the architecture of multiple versions of computer-based systems (system families). PCL has evolved from module interconnection languages, and its novel features include the ability to model the variability between members of a system family and facilities for the integrated modelling of hardware, software and documentat...

The data presented here are related to the research paper entitled "PCL-b-P(MMA-co-DMAEMA)2 new triblock copolymer for novel pH-sensitive nanocapsules intended for drug delivery to tumors" by Franco et al. [1]. Characterization data of PCL-diol, macroinitiator Br-PCL-Br, homopolymers (PMMA and PDMAEMA) and copolymers (batch 1 and batch 2) analyzed by FTIR, SEC and NMR, as well as, characterizat...
