We examine the basis set convergence of the CCSD(T) method for obtaining the structures of the 108 neutral first- and second-row species in the W4-11 database (with up to five non-hydrogen atoms). This set includes a total of 181 unique bonds: 75 H-X, 49 X-Y, 43 X=Y, and 14 X≡Y bonds (where X and Y are first- and second-row atoms). As reference values, geometries optimized at the CCSD(T)/aug'-cc-pV(6+d)Z level of theory are used. We consider the basis set convergence of the CCSD(T) method with the correlation consistent basis sets cc-pV(n+d)Z and aug'-cc-pV(n+d)Z (n = D, T, Q, 5) and the Weigend-Ahlrichs def2-n ZVPP basis sets (n = T, Q)...

Changes to chondrocyte volume/morphology may have deleterious effects on extracellular matrix (ECM) metabolism potentially leading to cartilage deterioration and osteoarthritis (OA). The factors controlling chondrocyte properties are poorly understood however pericellular matrix (PCM) weakening may be involved. We have studied the density, volume, morphology and clustering of cultured bovine articular chondrocytes within stiff (2%w/v) and soft (0.2%w/v) 3-dimensional agarose gels. Gels with encapsulated chondrocytes were cultured in Dulbecco's Modified Eagle's Medium (DMEM; foetal calf serum (FCS) 1-10%;380mOsm) for up to 7d...

BACKGROUND: Post-operative atrial fibrillation (POAF) is a major health economic burden. However, the precise mechanisms in POAF remain unclear. In other forms of AF, sites of high dominant frequency (DF) in sinus rhythm (SR) may harbour 'AF nests'. We studied AF inducibility in relation to substrate changes using epicardial electrograms and cardiomyocyte calcium handling in the atria of AF naïve patients. METHOD: Bipolar electrograms were recorded from the lateral right atrial (RA) wall in 34 patients undergoing coronary surgery using a high-density array in sinus rhythm (NSR)...

We propose and have evaluated a method to measure hip friction during wear testing on a popular multi-station hip simulator. A 6-degree-of-freedom load cell underneath the specimen sensed forces and torques during implant wear testing of simulated walking. This included internal-external and adduction-abduction rotations which are often neglected during friction testing on pendulum-type machines. Robust mathematical analysis and data processing provided friction estimates in three simultaneous orthogonal rotations, over extended multi-million cycle wear tests...

Increased APP (amyloid precursor protein) processing causes β-amyloid (Aβ) accumulation in autosomal dominant Alzheimer's disease (AD), but it is unclear if it also affects sporadic Aβ accumulation. We tested healthy controls and patients with mild cognitive symptoms (N=331) in the BioFINDER study, using cerebrospinal fluid (CSF) Aβ40 as a surrogate for amyloidogenic APP processing. We find that levels of brain Aβ fibrils (measured by 18F-flutemetamol PET) are independently associated with high CSF Aβ40 (P<0...

BACKGROUND: The risk of sporadic colorectal cancer (CRC) is strongly influenced by Iifestyle, environmental and genetic factors. Protein tyrosine phosphatases belong to a group of enzymes whose role in CRC has not yet been intensively studied. They play an important role in activation/de-activation of many enzymes, influencing cell biology by catalyzing reactions opposing those catalyzed by kinases. Protein tyrosine phosphatase receptor-like type Q (PTPRQ) and protein tyrosine phosphatase receptor-like type Z polypeptide 1 (PTPRZ1) have both been shown to be important in development of many cancer types including CRC...

PURPOSE: When surgeons disagree about the role of surgery, patient values and preferences should drive decision-making, but there is evidence that surgeon preferences have substantial influence. Surgeon preferences may relate to surgeon personality. Our primary null hypothesis is that specific personality characteristics (work styles) are not associated with the recommendation for operative treatment accounting for surgeon demographics. PATIENTS AND METHODS: We invited members of the Science of Variation Group to assess images of 15 upper extremity injuries with debatable indications for surgery, recommended operative or non-operative treatment, and grade their confidence in this decision (n = 270); subsequently, participants completed the validated Octogram Work and Leadership Style Test (n = 223)...

A green, facile, fast, and sensitive liquid-phase microextraction method is presented for the extraction and preconcentration of hemin in the presence of free iron ions prior to flame atomic absorption spectroscopic determination. In this technique, an anion-functionalized task-specific ionic liquid is used as the extracting solvent. The interface between the extracting solvent and the bulk aqueous phase containing hemin is enormously enlarged by dispersing the ionic liquid to the aqueous phase with the help of ultrasound radiation...
