The torque teno virus (TTV) is a recently discovered DNA virus that has been detected in many different hosts, including humans, livestock and poultry. To date, there is no report of pigeon TTV (PTTV) from anywhere in the world. To investigate the distribution of PTTV in pigeons from the eastern Chinese province of Jiangsu and characterize their genomes, we employed PCR to detect PTTV in 144 samples collected from 6 pigeon plants in Jiangsu province, amplify complete genomes from representative samples and analyze genetic characteristics using bioinformatics...

INTRODUCTION: One of the strategies for the rational use of antibiotics is the use of the score for community-acquired pneumonia (CAP Score). This instrument clinically evaluates patients with community-acquired pneumonia, thereby facilitating decision making regarding the early and safe withdrawal of antibiotics. OBJECTIVE: To generate a translation and cross-cultural adaptation of the Community-Acquired Pneumonia (CAP) Score questionnaire in Spanish. MATERIALS AND METHODS: Authorization for cross-cultural adaptation of the Community-Acquired Pneumonia (CAP) Score questionnaire was obtained; the recommendations of the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) and the European Organisation for Research and Treatment of Cancer (EORTC) were carried out through the following stages: forward translation, reconciliation, backward translation, harmonization, obtaining a provisional questionnaire, and applying the questionnaire in a pilot test...

In this study, folic acid-conjugated lipid nanoparticles were successfully prepared to enhance the active targeting of capsaicin (CAP) in ovarian cancers. The particles were nanosized and exhibited a controlled release of drug in the physiological conditions. The folic acid (FA)-conjugated system exhibited a remarkably higher uptake of nanoparticles in the cancer cells compared to that of non-targeted system. The folate-conjugated CAP-loaded lipid nanoparticles (CFLN) upon interacting with cancer cells were internalized via receptor-mediated endocytosis mechanism and resulted in higher concentration in the cancer cells...

With the advantages of excellent optical properties and biocompatibility, single-strand DNA-functionalized quantum dots have been widely applied in biosensing and bioimaging. A new aptasensor with easy operation, high sensitivity, and high selectivity was developed by immobilizing the aptamer on water soluble l-cysteine capped ZnS quantum dots (QDs). Graphene oxide (GO) sheets are mixed with the aptamer-QDs. Consequently, the aptamer-conjugated QDs bind to the GO sheets to form a GO/aptamer-QDs ensemble. This aptasensor enables the energy transfer based on a fluorescence resonance energy transfer (FRET) from the QDs to the GO sheets, quenching the fluorescence of QDs...

High aspect-ratio Fe nanostrips are known to reversibly switch from a single-domain magnetic state to a multidomain diamond pattern as a function of temperature (T) and width. This magnetic bistability can be understood by the temperature-dependent balance between magnetocrystalline, shape and magnetoelastic anisotropies and has potential applications in magnetic logic devices. However, as Fe nanostructures easily oxidize, protecting the surface with capping layers may be required, which could largely affect the anisotropy balance...

The troponin (Tn) is a ternary complex consisting of three subunits TnC, TnI and TnT; molecular disruption of the Tn complex has been recognized as an attractive strategy against neuropathic pain. Here, a self-inhibitory peptide is stripped from the switch region of TnI interaction interface with TnC, which is considered as a lead molecular entity and then used to generate potential peptide disruptors of TnC-TnI interaction based on a rational molecular design protocol. The region is a helical peptide segment capped by N- and C-terminal disorders...

Lead halide perovskites have emerged as low-cost, high-performance optical and optoelectronic materials, however, their material stability has been a limiting factor for broad applications. Here, we demonstrate stable core-shell colloidal perovskite nanocrystals using a novel, facile and low-cost co-polymer templated synthesis approach. The block co-polymer serves as a confined nano-reactor during perovskite crystallization and passivates the perovskite surface by forming a multidentate capping shell, thus significantly improving its photo-stability in polar solvents...

Telomeric G-quadruplexes have recently emerged as drug targets in cancer research. Herein, we present the first NMR structure of a telomeric DNA G-quadruplex that adopts the biologically relevant hybrid-2 conformation in a ligand-bound state. We solved the complex with a metalorganic gold(III) ligand that stabilizes G-quadruplexes. Analysis of the free and bound structures reveals structural changes in the capping region of the G-quadruplex. The ligand is sandwiched between one terminal G-tetrad and a flanking nucleotide...

In this work, a highly sensitive, citrate anion-capped gold nanoparticles (AuNPs)-based assay for the determination of propranolol in real samples with resonance Rayleigh scattering (RRS) and colorimetry was developed. When AuNPs were prepared by the sodium citrate reduction method, citrate anions self-assembled on the surface of AuNPs to form supramolecular complex anions. In BR 4.6 buffer solution, propranolol was positively charged and could bind with AuNPs to form larger aggregates through electrostatic force and hydrophobic effects...

BACKGROUND: Many middle-income countries are scaling up health insurance schemes to provide financial protection and access to affordable medicines to poor and uninsured populations. Although there is a wealth of evidence on how high income countries with mature insurance schemes manage cost-effective use of medicines, there is limited evidence on the strategies used in middle-income countries. This paper compares the medicines management strategies that four insurance schemes in middle-income countries use to improve access and cost-effective use of medicines among beneficiaries...

A series of nonhydroxamate HDAC6 inhibitors were prepared in our effort to develop potent and selective compounds for possible use in central nervous system (CNS) disorders, thus obviating the genotoxicity often associated with the hydroxamates. Halogens are incorporated in the cap groups of the designed mercaptoacetamides in order to increase brain accessibility. The indole analogue 7e and quinoline analogue 13a displayed potent HDAC6 inhibitory activity (IC50, 11 and 2.8 nM) and excellent selectivity against HDAC1...

Protein-losing enteropathy (PLE) is characterized by loss of serum proteins into the gastrointestinal tract. It may lead to hypoproteinemia and clinically present as protein deficiency edema, ascites, pleural or pericardial effusion and/or malnutrition. In most cases the site of protein loss is the small intestine. Here we present an unusual case of severe PLE in a 55-year old female with a one-year history of recurrent diarrhea, crampy abdominal pain, and peripheral edema. Endoscopy and MRI showed a diffuse inflammatory thickening of the sigmoid colon and the rectum...

The association-dissociation of the cap-binding protein eIF4E with eIF4G is a key control step in eukaryotic translation. The paradigm on the eIF4E-eIF4G interaction states that eIF4G binds to the dorsal surface of eIF4E through a single canonical alpha-helical motif, while metazoan 4E-BPs (m4E-BPs) advantageously compete against eIF4G thanks to a bi-modal binding onto the canonical but additionally to a non-canonical motif in the lateral eIF4E surface thus inhibiting translation. Very recently, it has been shown that metazoan eIF4Gs share this extended binding interface with m4E-BPs, with significant implications on the understanding of translation regulation and the design of therapeutic molecules...

Multi-drug resistant Acinetobacter baumannii (MDR-Ab), an opportunistic pathogen associated with nosocomial and combat related infections, has a high mortality due to its virulence and limited treatment options. Deletion of the thioredoxin gene (TrxA) from a clinical isolate of MDR-Ab resulted in a 100-fold increase in 50% lethal dose (LD50) in a systemic challenge murine model. Thus, we investigated the potential use of this attenuated strain as a live vaccine against MDR-Ab. Mice were vaccinated by subcutaneous (s...

BACKGROUND: The assessment of fibrosis and inflammatory activity is essential to identify patients with non-alcoholic fatty liver disease (NAFLD) at risk for progressive disease. Serum markers and ultrasound-based methods can replace liver biopsy for fibrosis staging, whereas non-invasive characterization of inflammatory activity remains a clinical challenge. Cell-free DNA (cfDNA) is a novel non-invasive biomarker for assessing cellular inflammation and cell death, which has not been evaluated in NAFLD...
