OBJECTIVE: This experiment was conducted to investigate the effects of fungal treated oil palm fronds (FTOPF) on performance, carcass traits, meat quality, and muscle chemical composition. METHODS: Eighteen growing crossbred male goats (Thai Native×Anglo Nubian) with 18.7±2.0 kg of initial body weight (BW) were stratified and blocked by BW in a randomized complete block design. Three diets containing 30% of oil palm fronds (OPF) either untreated (UOPF) or treated with Lentinussajor-caju (FTOPF) with or without urea (FTOPFU) were used as roughage sources in total mixed rations (TMRs)...

Ultrafast charge recombination in hematite (α-Fe2O3) severely limits its applications in solar energy conversion and utilization, for instance, in photo-electrochemical water splitting. We report the first time-domain ab initio study of charge relaxation dynamics in α-Fe2O3 with and without the oxygen vacancy (Ov) defect, using non-adiabatic molecular dynamics implemented within time-dependent density functional theory. The simulations show that the hole trapping is the rate-limiting step in the electron-hole recombination process for both neutral and ionized Ov systems...

Dynamic Nuclear Polarization (DNP), a technique that significantly enhances NMR signals, is experiencing a renaissance owing to enormous methodological developments. In the heart of DNP is a polarization transfer mechanism that endows nuclei with the much larger electronic spin polarization. Polarization transfer via the Overhauser effect is traditionally known to be operative only in liquids and conducting solids. Very recently, surprisingly strong Overhauser effect DNP in insulating solids has been reported, with a DNP efficiency that increases with the magnetic field strength...

Self-assembly has emerged as a promising method to control the structure and properties of ensembles of inorganic nanoparticles (NPs) for exploiting their collective effects. However, the rational assembly of inorganic NPs into soluble porous architectures as homogenized heterogeneous catalyst has been less studied. Here, we show that inorganic NPs can be used for the assembly of soluble porous coordination frameworks (PCFs) by atom-scale interfacial coordination-driven assembly strategy. Given large pore size, high dispersity in solution, strong absorption in the near-infrared range (NIR), and a long living electron-hole pair, the obtained soluble framework can serve as a platform for homogenize heterogeneous photocatalysts, which exhibited excellent activity, high apparent quantum efficiency, and recyclability to catalyze the noble metal free Suzuki coupling reaction under NIR light at room temperature...

Subhendu Roy, Johannes Kästner
Salicylate 1,2-Dioxygenase (SDO) is the first enzyme discovered, in the family of iron dioxygenases, to catalyze the ring cleavage of a monohydroxylated aromatic compound, salicylate, without a proton donor. Salicylate is not electron-rich like the familiar dihydroxy or aromatic substrates with an electron donating group that are utilized in the well-known dioxygenases. We investigated the full catalytic mechanism of SDO by a combination of Quantum Mechanics and Molecular Mechanics (QM/MM) calculations. We unravel the basis for the unexpected 'intra' cleavage regioselectivity in SDO...

Molecular imprinting has become a promising approach for synthesis of polymeric materials having binding sites with a predetermined selectivity for a given analyte, the so-called molecularly imprinted polymers (MIPs), which can be used as artificial receptors in various application fields. Realization of binding sites in a MIP involves the formation of prepolymerization complexes between a template molecule and monomers, their subsequent polymerization, and the removal of the template. It is believed that the strength of the monomer-template interactions in the prepolymerization mixture influences directly on the quality of the binding sites in a MIP and consequently on its performance...

The prevalence of lower urinary tract (LUT) symptoms increases with age but the etiology is unknown. This article aims to identify research directions that clarify the basis of this association. The initial question is whether biological age is the variable of interest or a time-dependent accumulation of factors that impact on LUT function at rates that differ between individuals. In particular, the accumulation of conditions or agents due to inflammatory states or tissue ischemia is important. Much of the above has been concerned with changes to bladder function and morphology...

Approximately half of the human brain is composed of white matter (WM), a specialized tissue housing the axonal projection of neurons and their necessary supporting glial cells. Axons course long distances from their parent soma, have a delicate structure, large surface area and in many cases are dependent upon a uniquely close morphological arrangement with myelinating oligodendrocyte partners; all factors that may predispose them to injury and disease. WM damage is central to a range of well-characterized disorders including multiple sclerosis and spinal cord injury and is also makes a significant contribution to disorders often considered to be largely focused in gray matter; for example, in stroke where ~49% of injury by volume is located in WM...

This study analyzes the incidence of transaction costs in the regionalization process of health policies in the Brazilian federal system. In this work, regionalized health actions contracted and agreed between federal agencies have assumed a transactional nature. A conceptual theoretical essay of reflective nature was prepared with the purpose of questioning and proposing new approaches to improve the health regionalization process. The main considerations suggest that institutional management tools proposed by the standards and regulations of the Unified Health System have a low potential to reduce transaction costs, especially due to hardships in reconciling common goals among the entities, environment surrounded by uncertainty, asymmetries and incomplete information, bounded rationality and conflict of interest...

BACKGROUND: Sporothrix brasiliensis is the most virulent sporotrichosis agent. This species usually responds to antifungal drugs, but therapeutic failure can occur in some patients. Antifungal susceptibility tests have been performed on this species, but no clinical breakpoints (CBPs) are available. In this situation, minimal inhibitory concentration (MIC) distributions and epidemiological cutoff values (ECVs) support the detection of identification of resistant strains. OBJECTIVES: To study the MIC distributions of five antifungal drugs against S...

FTIR spectroscopy of supersonic expansions is used to characterize alcohol dimers with one, two, and several nitrogen molecules attached to them. The nitrogen coating causes progressive spectral downshifts of the OH stretching fundamentals which are related to and explain matrix isolation shifts. Comparison of methanol, tert-butyl alcohol and ethanol as well as deuteration of methanol assist in the assignment. Alcohol monomers and trimers are significantly more resistant to nitrogen coating due to a lack of cooperativity and dangling bonds, respectively...

Electronegativity is a fundamental concept in chemistry. Despite its importance, the experimental determination has been limited only to ensemble-averaged techniques. Here, we report a methodology to evaluate the electronegativity of individual surface atoms by atomic force microscopy. By measuring bond energies on the surface atoms using different tips, we find characteristic linear relations between the bond energies of different chemical species. We show that the linear relation can be rationalized by Pauling's equation for polar covalent bonds...

This work reports a detailed resonant Raman scattering analysis of ZnMgO solid solution nanometric layers that are being developed for high efficiency chalcogenide solar cells. This includes layers with thicknesses below 100 nm and compositions corresponding to Zn/(Zn + Mg) content rations in the range between 0% and 30%. The vibrational characterization of the layers grown with different compositions and thicknesses has allowed deepening in the knowledge of the sensitivity of the different Raman spectral features on the characteristics of the layers, corroborating the viability of resonant Raman scattering based techniques for their non-destructive quantitative assessment...

Correct postoperative management is fundamental to prevent and treat complications and to optimize the success of filtering surgery. Timely control visits and appropriate actions and prescriptions ensure the best outcomes, allow recovery from a number of untoward events, and can reestablish filtration when failure seems imminent. In contrast, a slack follow-up and wrong interventions or prescriptions can lead to the failure of any surgery, no matter how accurately it was carried out, sometimes jeopardizing vision and even the anatomy of the globe...

REVIEW
Alan G Hinnebusch
Initiation of translation on eukaryotic mRNAs generally follows the scanning mechanism, wherein a preinitiation complex (PIC) assembled on the small (40S) ribosomal subunit and containing initiator methionyl tRNAi (Met-tRNAi) scans the mRNA leader for an AUG codon. In a current model, the scanning PIC adopts an open conformation and rearranges to a closed state, with fully accommodated Met-tRNAi, upon AUG recognition. Evidence from recent high-resolution structures of PICs assembled with different ligands supports this model and illuminates the molecular functions of eukaryotic initiation factors eIF1, eIF1A, and eIF2 in restricting to AUG codons the transition to the closed conformation...

INTRODUCTION: Since the discovery of the activating V617F mutation in Janus kinase 2 (JAK2), a number of pharmacologic inhibitors of JAK2 have entered clinical trials for patients with myelofibrosis. However, ruxolitinib, approved in 2011, remains the only one currently available for treatment of myelofibrosis, with many others having been discontinued for toxicity, and considerable uncertainty surrounding the future of those still in development. AREAS COVERED: The available clinical data on pacritinib and momelotinib, the two agents in the most advanced phases of clinical testing in myelofibrosis, are examined in detail...

In real applications, how to measure the uncertain degree of sensor reports before applying sensor data fusion is a big challenge. In this paper, in the frame of Dempster-Shafer evidence theory, a weighted belief entropy based on Deng entropy is proposed to quantify the uncertainty of uncertain information. The weight of the proposed belief entropy is based on the relative scale of a proposition with regard to the frame of discernment (FOD). Compared with some other uncertainty measures in Dempster-Shafer framework, the new measure focuses on the uncertain information represented by not only the mass function, but also the scale of the FOD, which means less information loss in information processing...
