Control over structure and composition of (ABO3) perovskite oxides offers exciting opportunities since these materials possess unique, tunable properties. Perovskite oxides with cobalt B-site cations are particularly promising, as the range of the cation's stable oxidation states leads to many possible structural frameworks. Here, we report growth of strontium cobalt oxide thin films by molecular beam epitaxy, and conditions necessary to stabilize different defect concentration phases. In situ X-ray scattering is used to monitor structural evolution during growth, while in situ X-ray absorption near-edge spectroscopy is used to probe oxidation state and measure changes to oxygen vacancy concentration as a function of film thickness...

Bovine tuberculosis is a zoonotic disease with largely unknown impact in Africa, with risk factors such as HIV and direct contact with animals or consumption of Mycobacterium bovis infected animal products. In order to understand and quantify this risk and design intervention strategies, good epidemiological studies are needed. Such studies can include molecular typing of M. bovis isolates. The aim of this study was to apply these tools to provide novel information concerning the distribution of bovine tuberculosis in cattle in Mozambique and thereby provide relevant information to guide policy development and strategies to contain the disease in livestock, and reduce the risk associated with transmission to humans...

BACKGROUND: An unprecedented Zika virus epidemic occurred in the Americas during 2015-2016. The size of the epidemic in conjunction with newly recognized health risks associated with the virus attracted significant attention across the research community. Our study complements several recent studies which have mapped epidemiological elements of Zika, by introducing a newly proposed methodology to simultaneously estimate the contribution of various risk factors for geographic spread resulting in local transmission and to compute the risk of spread (or re-introductions) between each pair of regions...

It has been established that a cationic rhodium(I)/(R)-BINAP complex catalyzes the asymmetric [2+2+2] cycloaddition of unsymmetrical α,ω-diynes with acenaphthylene at room temperature to give the corresponding chiral multicyclic compounds with high yields and ee values. Interestingly, enantioselectivity highly depended on the structures of α,ω-diynes used. The structural requirements of α,ω-diynes for high enantioselectivity were opposite to those in our previously reported cationic rhodium(I)/(R)-Difluorphos complex-catalyzed asymmetric [2+2+2] cycloaddition of α,ω-diynes with indene...

Phosphopantetheine adenylyltransferase (PPAT) is a rate limiting enzyme essential for biosynthesis of coenzyme A (CoA) which in turn is responsible to regulate the secretion of exotoxins via type III secretion system in Pseudomonas aeruginosa, causing severe health concerns ranging from nosocomial infections to respiratory failure. Acetyl Coenzyme A (AcCoA) is a newly reported inhibitor of PPAT, believed to regulate the cellular levels of CoA and thereby the pathogenesis. Very little is known so far regarding the mechanistic details of AcCoA binding inside PPAT binding cleft...

Bacterial nucleoid-associated proteins (NAPs) are critical to genome integrity and chromosome maintenance. Post-translational modifications of bacterial NAPs appear to function similarly to their better studied mammalian counterparts. The histone-like NAP HupB from Mycobacterium tuberculosis (Mtb) was previously observed to be acetylated by the acetyltransferase Eis, leading to genome reorganization. We report biochemical and structural aspects of acetylation of HupB by Eis. We also found that the SirT-family NAD+-dependent deacetylase Rv1151c from Mtb deacetylated HupB in vitro and characterized the deacetylation kinetics...

BACKGROUND AND AIMS: Persistent low back pain after initially successful surgery that is not attributed to structural deficits, is called failed back surgery syndrome (FBSS). When conservative and minimal invasive therapy fail, the recommended treatment is spinal cord stimulation (SCS). Because epidural fibrosis can be a contributing factor in the majority of FBSS patients, lumbosacral epiduroscopic lysis of adhesions may be considered as a less invasive alternative treatment option. We hypothesized that the use of epiduroscopic lysis of adhesions could reduce the need for SCS...

REVIEW
Alexandra V Rose, Katharine A Rimes
PURPOSE: Self-criticism is a transdiagnostic process that has been attracting research and clinical interest. The accurate measurement of this construct is therefore crucial; however, there are currently numerous measures of self-criticism and no guidelines about which to use in different contexts. This systematic review evaluated the measurement properties of self-report questionnaires of self-criticism. METHODS: OvidSP and Web of Science were used to search through multiple databases, and an initial grey literature search was completed...

An understanding of how historical fire and structure in dry forests (ponderosa pine, dry mixed conifer) varied across the western USA remains incomplete. Yet, fire strongly affects ecosystem services, and forest restoration programs are underway. We used General Land Office survey reconstructions from the late-1800s across 11 landscapes covering ∼1.9 million ha in four states to analyze spatial variation in fire regimes and forest structure. We first synthesized the state of validation of our methods using 20 modern validations, 53 historical cross-validations, and corroborating evidence...

Tendons are connective tissue structures of paramount importance to human ability of locomotion. The understanding of their physiology and pathology is gaining importance as advances in regenerative medicine are being made today. So far, very few studies were conducted to extend the knowledge about pathology, healing response and management of tendon lesions. In this paper we summarize actual knowledge on structure, process of healing and ageing of the tendons. The structure of tendon is optimized for the best performance of the tissue...

A dielectric spectroscopy study on a polyelectrolyte in aqueous solutions, which contains hydrophobic groups in part of the side chains poly(acrylic acid)-graft-poly(ethylene oxide)-graft-dodecyl (PAA-g-PEO-g-dodecyl) is reported. A refined double layer polarization model was proposed to analyze the double dielectric relaxations in the dielectric spectra. Various electrical and structural parameters of the copolymers were obtained. Besides the crossover concentration, another turning point around 4 mg mL-1 was identified through the analysis of all the dielectrical parameters including dielectric increment, relaxation time and correlation length...

Tin chalcogenides have shown promise in applications including energy storage, optoelectronics, photovoltaics, and thermoelectrics. Here, we present a colloidal synthesis strategy to produce tin dichalcogenide nanocrystals (NCs) with controllable stoichiometry, vacancies, shape, and crystal structure. Compared with previously reported methods, we use less expensive precursors, such as tin(iv) chloride and sulfur or selenium powder, to produce tin(iv) chalcogenide NCs. SnS2 and SnSe2 NCs with novel NC morphologies including SnS2 nanoflowers/nanoflakes, SnSe2 nanosheets with circular and hexagonal shapes, as well as mixtures of nanospheres and nanoflakes were prepared by varying the solvents and anion precursors...

BACKGROUND: The prescriber's directions to the patient (Sig) are one of the most quality-sensitive components of a prescription order. Owing to their free-text format, the Sig data that are transmitted in electronic prescriptions (e-prescriptions) have the potential to produce interpretation challenges at receiving pharmacies that may threaten patient safety and also negatively affect medication labeling and patient counseling. Ensuring that all data transmitted in the e-prescription are complete and unambiguous is essential for minimizing disruptions in workflow at prescribers' offices and receiving pharmacies and optimizing the safety and effectiveness of patient care...

OBJECTIVES: The risk of falling increases in adults over the age of 65. A common barrier to take up physical activity in sedentary older adults is the fear of falls and injury. Experiences of masters athletes can provide insights into management of the risk for falling. The purpose of this phenomenological study was to explore the fall-risk experience of masters athletes actively competing in sport. METHODS: Masters athletes over the age of 55 (n=22) described their experiences in semi-structured interviews...

Mixed and inconsistent findings have been reported across languages concerning grammatical morphology in speakers with Autism Spectrum Disorders (ASD). Some researchers argue for a selective sparing of grammar whereas others claim to have identified grammatical deficits. The present study aimed to investigate this issue in 26 participants with ASD speaking European French who were matched on age, gender and SES to 26 participants with typical development (TD). The groups were compared regarding their productivity and accuracy of syntactic and agreement categories using the French MOR part-of-speech tagger available from the CHILDES...
