The oxygen evolving complex (OEC) of photosystem II (PSII) gives rise to manganese-derived electron paramagnetic resonance (EPR) signals in the S0 and S2 oxidation states. These signals exhibit different microwave power saturation behavior between 4 and 10 K. Below 8 K, the S0 state EPR signal is a faster relaxer than the S2 multiline signal, but above 8 K, the S0 signal is the slower relaxer of t

A simple method for the formation of molecular recognition sites in polymer nanofibers was developed. Electrospun nanofibers were prepared from a Solution mixture of poly(ethylene terephthalate) (PET) and polyallylamine in the presence of a template molecule, 2,4-dichlorophenoxyacetic acid (2,4-D). The polyamine was used to provide functional groups that interact with the template during the elect

Background: The aim of this study was to examine the effect of preoperative smoking cessation interventions on postoperative complications and smoking cessation itself. Methods: Relevant databases were searched for randomized controlled trials (RCTs) of preoperative smoking cessation interventions. Trial inclusion, risk of bias assessment and data extraction were performed by two authors. Risk rat

Carl Charlier was a Swedish astronomer and statistician. He was influential in making mathematical statistics a university subject in Sweden. His main statistical contribution was the Gram‐Charlier expansions of continuous (Type A) and discrete (Type B) distributions. In astronomy he successfully created a hierarchical galaxy cluster model.

The pathogenesis of Alzheimer’s disease is widely believed to be due to production and deposition of the amyloid β-peptide. Several variants of the Aβ peptide are known to exist in in vivo. Variations include mutations or additional functional groups attached to residue side chains and may affect the aggregation process. Early on-set Alzheimer’s is caused by a variety of single amino acid substitu

Lignin depolymerisation can be utilized to produce value-added aromatic compounds. One of the major challenges in lignin depolymerisation study is the development of effective analytical tools to unravel the huge complexity of the depolymerisation product mixture. Traditional gas chromatography (GC) and high- performance liquid chromatography (HPLC) methods applied for this purpose are often in laLignin depolymerisation can be utilized to produce value-added aromatic compounds.

BACKGROUND: In mitral valve dysfunction, noninvasive measurement of transmitral blood flow is an important clinical examination. Flow imaging of the mitral valve, however, is challenging, since it moves in and out of the image plane during the cardiac cycle.PURPOSE: To more accurately measure mitral flow, a slice-following MRI phase contrast sequence is proposed. This study aimed to implement such
