TL;DR: Results demonstrated that a combined effect of both guidance cues was more effective than an individual cue, suggesting a potential use of A-PCL/PANi nanofibers for skeletal muscle regeneration.

TL;DR: It is concluded that HLA antibodies may be a prerequisite for chronic immunologic rejection, and 29 consecutive cases of chronic rejection failures as much as one year before the loss of grafts were found.
Abstract: Background. Recent studies show that almost all patients who have rejected a kidney transplant had human leukocyte antigen (HLA) antibodies. In this study, we sought to determine whether patients develop HLA antibodies before chronic rejection. Methods. For the past 8 years, 139 patients who had undergone kidney transplantation were systematically examined, using an enzyme-linked immunosorbent assay-based method, for the development of class-I and class-II HLA antibodies 3 months, 6 months, and yearly after transplantation. Chronic rejection was diagnosed by biopsy. Results. Among 29 patients with chronic rejection, 100% of the patients had HLA antibodies before rejection. Of these patients, 14 patients developed antibodies de novo. In contrast, among 110 patients with stable function, 27% of the patients developed HLA antibodies posttransplant (P<0.001). Conclusions. HLA antibodies were found in 29 consecutive cases of chronic rejection failures as much as one year before the loss of grafts. We conclude that HLA antibodies may be a prerequisite for chronic immunologic rejection.

TL;DR: In this article, the hydrogen bonding in hard and soft segments was examined for the extent of phase separation, and the microstructure was evidenced by differential scanning calorimetry (DSC).
Abstract: Three types of amine-containing polyurethanes and poly(urethane−ureas), N-methyldiethanolamine (MDEA) and/or tetraethylenepentamine (TEPA) as the chain extender and poly(ethylene glycol) of MW 400 as the soft-segment component, have been studied by FTIR. The hydrogen bonding in hard and soft segments was examined for the extent of phase separation, and the microstructure was evidenced by differential scanning calorimetry (DSC). The temperature effects on the hydrogen bonding were also investigated. They show a significant amount of hydrogen bonding between the hard and soft segments. It indicates that there exists a large amount of partial phase mixing of hard and soft segments compared to the conventional polyurethanes. The bulky CH3 groups of MDEA in hard segments restrict the hydrogen bonding within the hard segments, while the TEPA-containing urethane−urea polymers have more distinct phase separation. However, all of the polymers studied are amorphous materials such that the dissolved soft segments in...

Journal ArticleDOI
TL;DR: In this article, a series of operando measurements, including in situ X-ray absorption spectroscopy, liquid phase transmission electron microscopy, and in situ Raman spectrograms, were conducted to unravel in real time the structural and chemical stability of P-substituted CoSe2 electrocatalysts under both hydrogen and oxygen evolution reactions (HER and OER) in an alkaline electrolyte.
Abstract: The question of whether the metal chalcogenides (phosphides) that have been acknowledged to be efficient materials for bifunctional electrocatalysts really perform as the active species or just “pre-catalysts” has been debated Herein, a series of operando measurements, including in situ X-ray absorption spectroscopy, liquid-phase transmission electron microscopy, and in situ Raman spectroscopy, were conducted to unravel in real time the structural and chemical stability of P-substituted CoSe2 electrocatalysts under both hydrogen and oxygen evolution reactions (HER and OER, respectively) in an alkaline electrolyte It can be conclusively revealed that, in an alkaline electrolyte, the P-substituted CoSe2 electrocatalyst was acting as the “pre-catalyst” rather than the real reactive species The introduction of phosphorus is speculated to generate more vacancies or defects around Co cations in the initial CoSe2 and considerably facilitates the structural transformation into the “real reactive species”, such
