The canonical Wnt/β-catenin signaling pathway has been shown to play a major role during embryonic development and maturation of the central nervous system including the retina. It has a significant impact on retinal vessel formation and maturation, as well as on the establishment of synaptic structures and neuronal function in the central nervous system. Mutations in components of the Wnt/β-catenin signaling cascade may lead to severe retinal diseases, while dysregulation of Wnt signaling can contribute to disease progression. Apart from the angiogenic role of Wnt/β-catenin signaling, research in the last decades leads to the theory of a protective effect of Wnt/β-catenin signaling on damaged neurons. In this review, we focus on the neuroprotective properties of the Wnt/β-catenin pathway as well as its downstream signaling in the retina.

The isothermal low cycle fatigue (LCF) and thermomechanical fatigue (TMF) behaviour of a Ni-base superalloy was investigated. The results show that temperature plays an important role in both LCF and TMF. The alloy shows the lowest LCF fatigue resistance in the intermediate temperature range (～760℃). For strain-controlled TMF, in-phase (IP) cycling is more damaging than out-phase (OP) cycling. The high tempera- ture exposure in the TMF cycling influences the deformation behaviour at the low temperature. LCF lives at different temperatures, and IP and OP TMF lives are successfully correlated by using the hysteresis parameter Δσ·Δε_p.

Cisplatin, a platinum-based chemotherapeutic drug, has been used for over 30 years in a wide variety of cancers with varying degrees of success. In particular, cisplatin has been used to treat late stage non-small cell lung cancer （NSCLC） as the standard of care. However, therapeutic outcomes vary from patient to patient. Considerable efforts have been invested to identify biomark- ers that can be used to predict cisplatin sensitivity in NSCLC. Here we reviewed current evidence for cisplatin sensitivity biomarkers in NSCLC. We focused on several key pathways, including nucleotide excision repair, drug transport and metabolism. Both expression and germline DNA variation were evaluated in these key pathways. Current evidence suggests that cisplatin-based treatment could be improved by the use of these biomarkers.

Abstract: A array of the azimuthally averaged range-profile vectors and the inter-class and intra-class divergence matrixesare constructed iwth many frames of the high resolution range profiles which result from radar echoes of airplanes. Takingthe methods of whitening transformation and SVD produces a system of subspace vectors for target recognition. Where-upon, a template library for target recognition is built by the projection of a class-mean vector made from the radar dataonto the subspace for recognition. By Euclidean distance, a comparison is made between the above projection and eachtemplate in the library, to decide which class the target belongs to. Finally, simulations with the experimental radar dataarte given to show that the proposed method is robust to variation in azimuth and immune to additive Gaussian noisewhen SNr≥5dB.

“Absolutely riveting reading: A master piece.” (Sir Alan Cottrell) No more words could be said for a book already commented by another eminent scientist of the discipline, who is also a celebrated master in the understanding of materials and founding and growth of the science in the last half of a century at the end of the ten millennia since the use of fabrication and modification of man-made materials. We had the fortune and honour of receiving the earliest copies of the book in China during our meeting with the author either in England (Ko) or during the author’s visit to China as a Foreign Member of the Chinese
