CrRb: A molecule with large magnetic and electric dipole moments

We report calculations of Born-Oppenheimer potential energy curves of the chromium-rubidium heteronuclear molecule ((CrRb)-Cr-52-Rb-87), and the long-range dispersion coefficient for the interaction between ground state Cr and Rb atoms. Our calculated van der Waals coefficient (C-6 = 1770 a.u.) has an expected error of 3%. The ground state (6)Sigma(+) molecule at its equilibrium separation has a p

Recombinant human factor VIIa (rFVIIa) cleared principally by antithrombin following IV administration in haemophilia patients.

Objective: The objective of the present study was to evaluate the pharmacokinetics and the clearance pathways of rFVIIa after intravenous administration to haemophilia patients. Methods: Ten severe haemophilia patients were included in the study; all patients were intravenously administered a clinical relevant dose of 90 μg/kg (1.8 nmol/kg) rFVIIa. Blood samples were collected consecutively to des

Neutron Crystallographic Studies Reveal Hydrogen Bond and Water-Mediated Interactions between a Carbohydrate-Binding Module and Its Bound Carbohydrate Ligand.

Carbohydrate-binding modules (CBMs) are key components of many carbohydrate-modifying enzymes. CBMs affect the activity of these enzymes by modulating bonding and catalysis. To further characterize and study CBM-ligand binding interactions, neutron crystallographic studies of an engineered family 4-type CBM in complex with a branched xyloglucan ligand were conducted. The first neutron crystal stru

Adsorption, desorption, and surface-promoted hydrolysis of glucose-1-phosphate in aqueous goethite (alpha-feooh) suspensions

Adsorption, desorption, and precipitation reactions at environmental interfaces govern the fate of phosphorus in terrestrial and aquatic environments. Typically, a substantial part of the total pool of phosphorus consists of organophosphate, and in this study we have focused on the interactions between glucose-I-phosphate (G I P) and goethite (alpha-FeOOH) particles. The adsorption and surface-pro

Effectiveness of beads for tracking small-scale molecular motor dynamics

Investigations into molecular motor dynamics are increasingly focused on small-scale features of the motor's motion. We define performance measures of a common type of single-molecule motility assay, the bead assay, for its ability to detect such features. Using numerical models, we explore the dependence of assay performance on a number of experimentally controllable parameters, including bead si

Estrogens and phytoestrogens in male infertility.

PURPOSE OF REVIEW: A time-related negative trend in male reproductive function has been suggested. It has been hypothesized that this is due to exposure to chemicals interfering with the action of sex hormones. Also a negative effect of phytoestrogens on male fertility has been postulated. This review aimed to review the epidemiological evidence of deteriorating male reproductive function and summ

Supported liquid membrane as a novel tool for driving the equilibrium of ω-transaminase catalyzed asymmetric synthesis.

An attractive option to produce chiral amines of industrial importance is through asymmetric synthesis using ω-transaminase. However, reaching high yields often requires a strategy for shifting the equilibrium position. This paper describes a novel strategy for handling this problem. It involves the use of a supported liquid membrane (SLM) together with a packed bed reactor. The reactor contains E

Geriatric Experience Following Cardiac Arrest at Six Interventional Cardiology Centers in the United States 2006-2011: Interplay of Age, Do-Not-Resuscitate Order, and Outcomes.

It is not known if aggressive postresuscitation care, including therapeutic hypothermia and percutaneous coronary intervention, benefits cardiac arrest survivors more than 75 years old. We compared treatments and outcomes of patients at six regional percutaneous coronary intervention centers in the United States to determine if aggressive care of elderly patients was warranted.

High-pressure Raman and infrared spectroscopic studies of ZrP2O7

High-pressure Raman and mid-infrared spectroscopic studies were carried out on ZrP2O7 to 23.2 and 13 GPa respectively. In the pressure range 0.7-4.3 GPa the lattice mode at 248 cm(-1) disappears, new modes appear around 380 and 1111 cm(-1) and the strong symmetric stretching mode at 476 cm(-1) softens, possibly indicating a subtle phase transition. Above 8 GPa all the modes broaden, and all of the

SmartHand tactile display: A new concept for providing sensory feedback in hand prostheses.

Abstract A major drawback with myoelectric prostheses is that they do not provide the user with sensory feedback. Using a new principle for sensory feedback, we did a series of experiments involving 11 healthy subjects. The skin on the volar aspect of the forearm was used as the target area for sensory input. Experiments included discrimination of site of stimuli and pressure levels at a single st

Binding Affinities of Factor Xa Inhibitors Estimated by Thermodynamic Integration and MM/GBSA.

We present free energy estimates of nine 3-amidinobenzyl-1H-indole-2-carboxamide inhibitors of factor Xa. Using alchemical thermodynamic integration (TI) calculations, we estimate the difference in binding free energies with high accuracy and precision, except for mutations involving one of the amidinobenzyl rings. Crystal studies show that the inhibitors may bind in two distinct conformations, an

CCAAT/enhancer binding protein alpha (C/EBP alpha)-induced transdifferentiation of pre-B cells into macrophages involves no overt retrodifferentiation

Earlier work has shown that pre-B cells can be converted into macrophages by the transcription factor CCAAT/enhancer binding protein a at very high frequencies. Using this system, we performed a systematic analysis of whether during transdifferentiation the cells transiently reactivate progenitor-restricted genes or even retrodifferentiate. A transcriptome analysis of transdifferentiating cells sh

Extreme downside risk spillover from the United States and Japan to Asia-Pacific stock markets

This paper proposes a binary response model approach to measure and forecast extreme downside risks in Asia-Pacific markets given information on extreme downside risks in the U.S. and Japanese markets. The extreme downside risk of a market is measured as the occurrence of extreme downside movement—market returns falling below left-tail Value at Risk in a Markov switching framework. The empirical f

Use of a National Clinical Final Examination in a Bachelor’s Programme in Nursing to Assess Clinical Competence—Students’, Lecturers’ and Nurses’ Perceptions

Objective: The objective of this study was to evaluate the perceptions of students, lecturers, nurses and clinical lecturers regarding the ability of the National Clinical Final Examination (NCFE) to assess clinical competence, and whether the assessment was consistent with the qualifications for a Bachelor of Science in Nursing as outlined by the Swedish Higher Education Authority. The NCFE is di

Inhibition of Circulating Dipeptidyl Peptidase 4 Activity in Patients with Metastatic Prostate Cancer

Cancer is responsible for many deaths and is a major source of healthcare expenditures. The identification of new, non-invasive biomarkers might allow improvement of the direct diagnostic or prognostic ability of already available tools. Here, we took the innovative approach of interrogating the activity of exopeptidases in the serum of cancer patients with the aim of establishing a distinction ba

Jet mass and substructure of inclusive jets in root s=7 TeV pp collisions with the ATLAS experiment

Recent studies have highlighted the potential of jet substructure techniques to identify the hadronic decays of boosted heavy particles. These studies all rely upon the assumption that the internal substructure of jets generated by QCD radiation is well understood. In this article, this assumption is tested on an inclusive sample of jets recorded with the ATLAS detector in 2010, which corresponds

RBM3-Regulated Genes Promote DNA Integrity and Affect Clinical Outcome in Epithelial Ovarian Cancer.

The RNA-binding motif protein 3 (RBM3) was initially discovered as a putative cancer biomarker based on its differential expression in various cancer forms in the Human Protein Atlas (HPA). We previously reported an association between high expression of RBM3 and prolonged survival in breast and epithelial ovarian cancer (EOC). Because the function of RBM3 has not been fully elucidated, the aim of
