Abstract
Objectives The aim of this study was to investigate the effect of hyperglycaemia on oxidative stress markers and inflammatory and matrix gene expression within tendons of normal and diabetic rats and to give insights into the processes involved in tendinopathy. Methods Using tenocytes from normal Sprague-Dawley rats, cultured both in control and high glucose conditions, reactive oxygen species (ROS) production, cell proliferation, messenger RNA (mRNA) expression of NADPH oxidase (NOX) 1 and 4, interleukin-6 (IL-6), matrix metalloproteinase (MMP)-2, tissue inhibitors of matrix metalloproteinase (TIMP)-1 and -2 and type I and III collagens were determined after 48 and 72 hours in vitro. In an in vivo study, using diabetic rats and controls, NOX1 and 4 expressions in Achilles tendon were also determined. Results In tenocyte cultures grown under high glucose conditions, gene expressions of NOX1, MMP-2, TIMP-1 and -2 after 48 and 72 hours, NOX4 after 48 hours and IL-6, type III collagen and TIMP-2 after 72 hours were significantly higher than those in control cultures grown under control glucose conditions. Type I collagen expression was significantly lower after 72 hours. ROS accumulation was significantly higher after 48 hours, and cell proliferation after 48 and 72 hours was significantly lower in high glucose than in control glucose conditions. In the diabetic rat model, NOX1 expression within the Achilles tendon was also significantly increased. Conclusion This study suggests that high glucose conditions upregulate the expression of mRNA for NOX1 and IL-6 and the production of ROS. Moreover, high glucose conditions induce an abnormal tendon matrix expression pattern of type I collagen and a decrease in the proliferation of rat tenocytes. Cite this article: Y. Ueda, A. Inui, Y.

Abstract
Objectives Triamcinolone acetonide (TA) is widely used for the treatment of rotator cuff injury because of its anti-inflammatory properties. However, TA can also produce deleterious effects such as tendon degeneration or rupture. These harmful effects could be prevented by the addition of platelet-rich plasma (PRP), however, the anti-inflammatory and anti-degenerative effects of the combined use of TA and PRP have not yet been made clear. The objective of this study was to determine how the combination of TA and PRP might influence the inflammation and degeneration of the rotator cuff by examining rotator cuff-derived cells induced by interleukin (IL)-1ß. Methods Rotator cuff-derived cells were seeded under inflammatory stimulation conditions (with serum-free medium with 1 ng/ml IL-1ß for three hours), and then cultured in different media: serum-free (control group), serum-free + TA (0.1mg/ml) (TA group), serum-free + 10% PRP (PRP group), and serum-free + TA (0.1mg/ml) + 10% PRP (TA+PRP group). Cell morphology, cell viability, and expression of inflammatory and degenerative mediators were assessed. Results Exposure to TA significantly decreased cell viability and changed the cell morphology; these effects were prevented by the simultaneous administration of PRP. Compared with the control group, expression levels of inflammatory genes and reactive oxygen species production were reduced in the TA, PRP, and TA+PRP groups. PRP significantly decreased the expression levels of degenerative marker genes. Conclusions The combination of TA plus PRP exerts anti-inflammatory and anti-degenerative effects on rotator cuff-derived cells stimulated by IL-1ß. This combination has the potential to relieve the symptoms of rotator cuff injury. Cite this article: T. Muto, T. Kokubu, Y. Mifune, A. Inui, R. Sakata, Y. Harada, F. Takase, M. Kurosaka.

Abstract
Objectives To investigate the appropriate dose and interval for the administration
of triamcinolone acetonide (TA) in treating tendinopathy to avoid
adverse effects such as tendon degeneration and rupture. Methods Human rotator cuff-derived cells were cultured using three media:
regular medium (control), regular medium with 0.1 mg/mL of TA (low
TA group), and with 1.0 mg/mL of TA (high TA group). The cell morphology,
apoptosis, and viability were assessed at designated time points. Results In the low TA group, the cells became flattened and polygonal
at seven days then returned to normal at 21 days. The cell apoptosis
ratio and messenger ribonucleic acid expression of caspase-3, 7,
8, and 9 increased, and viability was reduced in the low and high
groups at seven days. In the low TA group, apoptosis and viability returned
to normal at 21 days, however, in the high TA group, the cell morphology,
apoptosis ratio, caspase-3, 7, 8, and 9 and viability did not return
by day 21. Re-administration was performed in the low TA group at
7-, 14-, and 21-day intervals, and cell viability did not return
to the control level at the 7- and 14-day intervals. Conclusion A 0.1 mg/mL dose of TA temporarily decreased cell viability and
increased cell apoptosis, which was recovered at 21 days, however,
1 mg/mL of TA caused irreversible damage to cell morphology and
viability. An interval > three weeks was needed to safely re-administer
TA. These findings may help determine the appropriate dose and interval
for TA injection therapy. Cite this article: Bone Joint Res 2014;3:328–34.

Abstract
The optical properties of copper Cu-Ni compound metal island (CMI) films composed of nanoclusters of an alloy of Cu and Ni have been experimentally investigated. The spectral characteristics of the Cu-Ni CMI films are intermediate between those of conventional Cu and Ni island films in visible and near-IR regions. In addition, the magneto-optic effect has been observed in the Cu-Ni CMI films. It is also shown that the Faraday rotation in the Cu-Ni CMI films can easily be controlled by selection of the mixture ratio of Cu and Ni.
