BACKGROUND: To date, there have been conflicting suggestions regarding theinitial pathogenesis of CTS.It has been characterized as either inflammation of the median nerve caused by compression ornon-inflammatory fibrosis of the subsynovial connective tissue (SSCT). OBJECTIVE: To investigate the initialpathogenesis of CTS, we compared the deformation and displacement of the median nerve in accordance with the electrophysiological severity between patients with CTS (via Bland`s scale) and healthy controls...

Accumulating evidence indicates that MERS-CoV originated from bat coronaviruses (BatCoVs). Previously, we demonstrated that both MERS-CoV and BatCoV HKU4 use CD26 as a receptor, but how the BatCoVs evolved to bind CD26 is an intriguing question. Here, we solved the crystal structure of the S1 subunit C-terminal domain of HKU5 (HKU5-CTD), another BatCoV that is phylogenetically related to MERS-CoV but cannot bind to CD26. We observed that the conserved core subdomain and those of other betacoronaviruses (betaCoVs) have a similar topology of the external subdomain, indicating the same ancestor of lineage C betaCoVs...

A 42-residue polypeptide conjugated to a small organic molecule capable of targeting the phosphorylated side chain of Ser-15 was shown to bind glycogen phosphorylase a (GPa) with a KD of 280 nM. The replacement of hydrophobic amino acids by Ala reduced affinities, whereas the incorporation of L-2-aminooctanoic acid (Aoc) increased affinities. Replacing Nle-5, Ile-9 and Leu-12 by Aoc reduced the KD from 280 nM to 27 nM. Downsizing the 42-mer to an 11-mer gave rise to an order of magnitude lower affinity for GPa but the 11-mer where Nle-5, Ile-9 and Leu-12 were replaced by Aoc showed a KD of 550 nM, comparable to that of the parent 42-mer...

A series of 9-mer and 13-mer amide-bridged cyclic peptides derived from the linear prototype Ac-PKIIQSVGIS-Nle-K-Nle-NH2 (Toro et al. ChemBioChem2013) has been designed and synthesized by introduction of the lactam between amino acid side chains that are separated by one helical turn (i, i+4). All of these compounds were tested in vitro as both dimerization and enzyme inhibitors of Leishmania infantum trypanothione reductase (Li-TryR). Three of the 13-mer cyclic peptide derivatives (3, 4 and 6) inhibited the oxidoreductase activity of Li-TryR in the low micromolar range and they also disrupted enzyme dimerization...

Silver(I) complexes of two designed tridentate ligands, namely, 2,6-(pyridyl)iminoditriazaadamantane (pydTAm) and 2,6-(pyridyl)iminodiadamantane (pydAm), have been synthesized and structurally characterized. [Ag(pydTAm)2](CF3SO3) (1), the hitherto unknown mer isomer of a silver(I) octahedral complex, crystallizes in a highly symmetric body-centered cubic I4̅3m space group. Quite in contrast, the Ag(I) center in the analogous [Ag(pydAm)2](CF3SO3) (2) complex resides in a trigonal-bipyramidal geometry and crystallizes in a triclinic P1̅ space group with two crystallographically independent molecules in the asymmetric unit...

Histones and their post-translational modifications have key roles in chromatin remodeling and gene transcription. Besides intranuclear functions, histones act as damage-associated molecules when they are released into the extracellular space. Administration of histones to animals leads to systemic inflammatory and toxic responses. Autoantibodies with enzymatic activities (abzymes) are distinctive features of some autoimmune and viral diseases. Electrophoretically homogeneous IgGs containing no canonical enzymes were isolated from the sera of HIV-infected patients by chromatography on several affinity sorbents including anti-histone Sepharose...

In genome analysis, k-mer-based comparison methods have become standard tools. However, even though they are able to deliver reliable results, other algorithms seem to work better in some cases. To improve k-mer-based DNA sequence analysis and comparison, we successfully checked whether adding positional resolution is beneficial for finding and/or comparing interesting organizational structures. A simple but efficient algorithm for extracting and saving local k-mer spectra (frequency distribution of k-mers) was developed and used...

The presence of naturally occurring resistance-associated substitutions (RASs) in the HCV-protease domain has been poorly investigated in the liver, the main site of HCV replication. We evaluated the natural resistance of the virus to NS3 protease inhibitors in liver tissue and plasma samples taken from HCV-infected patients. RASs were investigated by means of viral population sequencing in liver tissue samples from 18 HCV-infected patients harbouring genotype 1a or genotype 1b; plasma samples from 12 of these patients were also available for virological investigation...

Significant sequence variation of Middle East respiratory syndrome coronavirus (MERS CoV) has never been detected since it was first reported in 2012. A MERS patient came from Korea to China in late May 2015. The patient was 44 years old and had symptoms including high fever, dry cough with a little phlegm, and shortness of breath, which are roughly consistent with those associated with MERS, and had had close contact with individuals with confirmed cases of MERS.After one month of therapy with antiviral, anti-infection, and immune-enhancing agents, the patient recovered in the hospital and was discharged...

The success of high-resolution melting (HRM) analysis for distinguishing similar DNAs with minor base mismatch differences is limited. Here, metal-mediated structural change in DNA has been exploited to amplify HRM signals leading to differentiation of target DNAs in an orthologous gene corresponding to four Plasmodium species. Conserved 26-mer ssDNAs from ldh gene of the four Plasmodium species were employed as targets. A capture probe (CP) that is fully complementary to the Plasmodium falciparum target (FT) and has two base mismatches each, with the targets of Plasmodium vivax (VT), Plasmodium malariae, (MT), and Plasmodium ovale (OT), was considered...

The application of nanotechnology in the health care setting has many potential benefits; however, our understanding of the interactions between nanoparticles and our immune system remains incomplete. Although many of the biological effects of nanoparticles are negatively correlated with particle size, some are clearly size specific and the mechanisms underlying these size-specific biological effects remain unknown. Here, we examined the pro-inflammatory effects of silica particles in THP-1 cells with respect to particle size; a large overall size range with narrow intervals between particle diameters (particle diameter: 10, 30, 50, 70, 100, 300, and 1,000 nm) was used...

Middle East respiratory syndrome coronavirus (MERS CoV) is a recently evolved fatal respiratory disease that poses a concern for a global epidemic. MERS CoV encodes 2 proteases, 3C-like protease (3CLpro) and papain-like protease (PLpro). These proteases share in processing MERS CoV polyproteins at different sites to yield 16 nonstructural proteins. In this work, we provide evidence that MERS CoV 3CLpro and PLpro are subject to different genetic and evolutionary influences that shape the protein sequence, codon usage pattern, and codon usage bias...

Replication of Vibrio cholerae chromosome 2 (Chr2) depends on molecular chaperone DnaK to facilitate binding of the initiator (RctB) to the replication origin. The binding occurs at two kinds of site, 12-mers and 39-mers, which promote and inhibit replication, respectively. Here we show that DnaK employs different mechanisms to enhance the two kinds of binding. We found that mutations in rctB that reduce DnaK binding also reduce 12-mer binding and initiation. The initiation defect is suppressed by second-site mutations that increase 12-mer binding only marginally...

In addition to the impact of a disease itself, public reaction could be considered another outbreak to be controlled during an epidemic. Taiwan's experience with SARS in 2003 highlighted the critical role played by the media during crisis communication. After the SARS outbreak, Taiwan's Centers for Disease Control (Taiwan CDC) followed the WHO outbreak communication guidelines on trust, early announcements, transparency, informing the public, and planning, in order to reform its risk communication systems. This article describes the risk communication framework in Taiwan, which has been used to respond to the 2009-2016 influenza epidemics, Ebola in West Africa (2014-16), and MERS-CoV in South Korea (2015) during the post-SARS era...

Next-generation sequencing technology generates a huge number of reads (short sequences), which contain a vast amount of genomic data. The sequencing process, however, comes with artifacts. Preprocessing of sequences is mandatory for further downstream analysis. We present Zseq, a linear method that identifies the most informative genomic sequences and reduces the number of biased sequences, sequence duplications, and ambiguous nucleotides. Zseq finds the complexity of the sequences by counting the number of unique k-mers in each sequence as its corresponding score and also takes into the account other factors such as ambiguous nucleotides or high GC-content percentage in k-mers...

Relative energies and binding energies are crucial quantities, which determine various molecular properties of ice and water. We developed a new effective method to compute those energies of bulk ice-liquid water systems. In this work, ten ice-liquid 144-mers and ten periodic ice-liquid (H2O)64 systems are taken out from the molecular dynamics simulations in the melting process of ice-Ih crystals. They are investigated at the levels of density functional theory (DFT), explicitly correlated second-order Møller-Plesset perturbation theory (MP2-F12) and coupled-cluster singles and doubles with noniterative triples corrections [CCSD(T)-F12b] in the framework of generalized energy-based fragmentation approach...

Cytotoxic T lymphocyte (CTL) epitope peptide-based vaccines are widely used in cancer and infectious disease therapy. We previously generated an immune-tolerant elastin-like polypeptides (iTEPs)-based carrier to deliver a peptide CTL vaccine and enhance the efficiency of the vaccine. To further optimize the vaccine carrier, we intended to potentiate its function by designing an iTEP-based carrier that was able to deliver adjuvant and a vaccine epitope as one molecule. Thus, we fused a 9-mer H100, a peptide derived from the high-mobility group box 1 protein (HMGB1) that could induce activation of dendritic cells (DCs), with an iTEP polymer to generate a new iTEP polymer named H100-iTEP...
