Human African trypanosomiasis (HAT), Chagas disease, and leishmaniasis present a significant burden across the developing world. Existing therapeutics for these protozoal neglected tropical diseases suffer from severe side effects and toxicity. Previously, NEU-1045 (3) was identified as a promising lead with cross-pathogen activity, though it possessed poor physicochemical properties. We have designed a library of analogues with improved calculated physicochemical properties built on the quinoline scaffold of 3 incorporating small, polar aminoheterocycles in place of the 4-(3-fluorobenzyloxy)aniline substituent...

The inherent difficulty of discovering new and effective antibacterials and the rapid development of resistance particularly in Gram-negative bacteria, illustrates the urgent need for new methods that enable rational drug design. Here we report the development of 3D imaging cluster secondary ion mass spectrometry (SIMS) as a label-free approach to chemically map small molecules in aggregated and single Escherichia coli cells, with ~300 nm spatial resolution and high chemical sensitivity. The feasibility of quantitative analysis was explored, and a non-linear relationship between treatment dose and signal for tetracycline and ampicillin, two clinically-used antibacterials, was observed...

3,4,9,10-perylene tetracarboxylic diimide molecules were evaporated onto a Ag/Si(111)-√3 × √3 surface and studied by scanning tunneling microscopy/spectroscopy and low energy electron diffraction (LEED). The growth mode was characterized as layer-by-layer growth with a single molecular unit cell in a short range order. The growth of the first two monolayers involves a molecule/substrate superstructure and a molecule/molecule superstructure. At higher coverages, the molecules in each layer were found to align so that unit cells are on top of each other...

The remarkable properties of graphene stem from its two-dimensional (2D) structure, with a linear dispersion of the electronic states at the corners of the Brillouin zone (BZ) forming a Dirac cone. Since then, other 2D materials have been suggested based on boron, silicon, germanium, phosphorus, tin, and metal di-chalcogenides. Here, we present an experimental investigation of a single silicon layer on Au(111) using low energy electron diffraction (LEED), high resolution angle-resolved photoemission spectroscopy (HR-ARPES), and scanning tunneling microscopy (STM)...

Introduction The Index of Orthognathic Functional Treatment Need (IOFTN) was developed to measure functional difficulties arising from malocclusions related to facial deformity. The IOFTN is not currently being used to determine suitability for orthognathic treatment, however, it is a useful aid for assessing and referring patients and takes into account functional and facial appearance. This paper aims to evaluate the potential impact of introduction of the IOFTN on the future provision of orthognathic services...

Hexagonal boron nitride (h-BN), an atomically thin insulating material, shows a large band gap, mechanical flexibility, and optical transparency. It can be stacked with other two-dimensional (2D) materials through van der Waals interactions to form layered heterostructures. These properties promise its application as an insulating layer of novel 2D electronic devices due to its atomically smooth surface with a large band gap. Herein, we demonstrated the ambient-pressure chemical vapour deposition (CVD) growth of high-quality, large-area monolayer h-BN on a Cu(111) thin film deposited on a c-plane sapphire using ammonia borane (BH3NH3) as the feedstock...

R M Tromp, M S Altman
Accurately measuring defocus in cathode lens instruments (Low Energy Electron Microscopy - LEEM, and Photo Electron Emission Microscopy - PEEM) is a pre-requisite for quantitative image analysis using Fourier Optics (FO) or Contrast Transfer Function (CTF) image simulations. In particular, one must establish a quantitative relation between lens excitation and image defocus. One way to accomplish this is the Real-Space Microspot LEED method, making use of the accurately known angles of diffracted electron beams, and the defocus-dependent shifts of their corresponding real-space images...

Patients with isolated peripheral branch neuralgia of trigeminal nerve usually receive traditional treatment such as medical therapy and interventional procedures targeting the entire trigeminal nerve or related ganglions. However, if the intractable pain is limited to a certain branch, the patient may also benefit from a peripheral and nerve-targeted interventional approach. Here, we report the management of a patient with isolated infraorbital neuralgia by ultrasound-guided infraorbital nerve block with steroid and local anesthetic combination...
