Hydrogenasen sind H2-umsetzende Metalloenzyme und enthalten katalytische Kofaktoren, deren Eisenionen durch biologisch ungewöhnliche Kohlenmonoxid- (CO) Cyanid- (CN−) Liganden koordiniert sind. Externes CO CN−hemmt jedoch. Der molekulare Mechanismus der Bindung von CN− an [FeFe]-Hydrogenasen ist unbekannt. In dieser Studie präsentieren wir Kristallstrukturen mit behandelten [FeFe]-Hydrogenase C...

We investigated the role of tumor copy number (CN)-altered genome (CN-AG) in the carcinogenesis of cervical cancer (CC), especially its effect on gene expression, biological processes, and patient survival. Fifty-nine human papillomavirus 16 (HPV16)-positive CCs were investigated with microarrays-31 for mapping CN-AG and 55 for global gene expression, with 27 CCs in common. Five-year survival w...

The catalytic capability of original carbon nitride (CN) is limited by a small specific surface area and high electron–hole recombination rate. In this study, WO3-loaded porous nanosheets (MCA-CN/WO3) were synthesized thermal treatment with melamine, cyanuric acid WCl6. MCA-CN/WO3 could degrade 98% the methylene blue (MB) within 30 min in photo-Fenton-like process, displaying better activity th...

Discrete nonlinear Schröginger equation (DNLS) of the form, in dt = Cn+1 + Cn−1 χn[|Cn+1| + |Cn−1| − 2|Cn|]Cn is used to study the formation of stationary localized states in one dimensional system due to a single as well as a dimeric nonlinear impurity. The fully nonlinear chain is also considered. The stability of the states and its connection with the nonlinear strength is presented. Results...

Layered copper-nickel cyanide, CuNi(CN)4, a 2-D negative thermal expansion material, is one of a series of copper(ii)-containing cyanides derived from Ni(CN)2. In CuNi(CN)4, unlike in Ni(CN)2, the cyanide groups are ordered generating square-planar Ni(CN)4 and Cu(NC)4 units. The adoption of square-planar geometry by Cu(ii) in an extended solid is very unusual.

Observations of CN and CH band strengths among a random sample of main-sequence turn-off stars (+3.9 < MV < +4.6) in the globular cluster 47 Tuc (NGC 104, C0021-723) were made with the CTIO Argus fiber spectrograph for the purpose of determining the ratio of CN-strong to CN-weak stars and investigating the behavior of CH relative to CN. Of the 20 turn-off stars, 12 were found to be CN-strong wh...

BACKGROUND AND PURPOSE The cisternal segments of the lower cranial nerves (CNs) adjacent to the jugular foramen (JF) are difficult to identify reliably by routine MR imaging. We performed a 3D balanced fast-field echo imaging technique (3D-bFFE) to obtain detailed anatomy of the cisternal segments of CNs IX, X, and XI. MATERIALS AND METHODS 3D-bFFE was used to image the cisternal segments of ...

BACKGROUND The infrafloccular approach was introduced as a variation in microvascular decompression (MVD) for hemifacial spasm. However, the rate of postoperative lower cranial nerve (CN) palsy can be high. This study investigated the surgical factors in relation to the occurrence of postoperative lower CN palsy. METHODS The case records of 103 patients who underwent MVD were reviewed. Dissec...
