Retraction: A reduction state potentiates the glucocorticoid response through receptor protein stabilization

Retraction: The above article in Genes to Cells (doi: 10.1111/j.1365‐2443.2007.01131.x ), published online on 2 November 2007 in Wiley Online Library ( http://onlinelibrary.wiley.com/ ), has been retracted by agreement between the authors, the journal Editor in Chief, Mitsuhiro Yanagida, and Wiley Publishing Asia Pty Ltd. The retraction has been agreed to due to lack of the gel images for the lanes 1, 2, 5, 6, 9 and 10 of ‘GR’ and lanes 1, 2, 9 and 10 of ‘Brg‐1’ in Figure 3(D) and the multiple usage of the gel images in Figure 3(B) and (C).     

Recent progress in porphyrin- and phthalocyanine-containing perovskite solar cells

In this review, we summarize the application of porphyrins and phthalocyanines in perovskite solar cells to date. Since the first porphyrin- and phthalocyanine-based perovskite solar cells were reported in 2009, their power conversion efficiency has dramatically increased from 3.9% to over 20%. Porphyrins and phthalocyanines have mostly been used as the charge selective layers in these cells. In some cases, they have been used inside the perovskite photoactive layer to form two-dimensional perovskite structures. In other cases, they were used at the interface to engineer the surface energy level. This review gives a chronological introduction to the application of porphyrins and phthalocyanines for perovskite solar cells depending on their role. This review article also provides the history of porphyrin and phthalocyanine derivative development from the perspective of perovskite solar cell applications.

Accurate and Easy Measurement of Sliding Distance of Intramedullary Nail in Trochanteric Fracture

Background

In daily clinical practice, it is essential to properly evaluate the postoperative sliding distance of various femoral head fixation devices (HFD) for trochanteric fractures. Although it is necessary to develop an accurate and reproducible method that is unaffected by inconsistent postoperative limb position on radiography, few studies have examined which method is optimal. Therefore, the purpose of this study is to prospectively compare the accuracy and reproducibility of our four original methods in the measurement of sliding distance of the HFD.

Methods

Radiographs of plastic simulated bone implanted with Japanese proximal femoral nail antirotation were taken in five limb postures: neutral, flexion, minute internal rotation, greater external rotation, and flexion with external rotation. Orthopedic surgeons performed five measurements of the sliding distance of the HFD in each of the flowing four methods: nail axis reference (NAR), modified NAR, inner edge reference, and nail tip reference. We also assessed two clinical cases by using these methods and evaluated the intraclass correlation coefficients.

Results

The measured values were consistent in the NAR method regardless of limb posture, with an even smaller error when using the modified NAR method. The standard deviation (SD) was high in the nail tip reference method and extremely low in the modified NAR method. In the two clinical cases, the SD was the lowest in the modified NAR method, similar to the results using plastic simulated bone. The intraclass correlation coefficients showed the highest value in the modified NAR method.

Conclusions

We conclude that the modified NAR method should be the most recommended based on its accuracy, reproducibility, and usefulness.
