Determinations of the form factors of semileptonic \(D\rightarrow K\) decays and leptoquark constraints

By analyzing all existing measurements for \( D\rightarrow K \ell ^+ \nu _{\ell } \) (\(\ell =e,\ \mu \)) decays, we find that the determinations of both the vector form factor \(f_+^K(q^2)\) and scalar form factor \(f_0^K(q^2)\) for semileptonic \(D\rightarrow K\) decays from these measurements are feasible. By taking the parameterization of the one order series expansion of the...

Effects of Soil Salinity on the Expression of Bt Toxin (Cry1Ac) and the Control Efficiency of Helicoverpa armigera in Field-Grown Transgenic Bt Cotton

An increasing area of transgenic Bacillus thuringiensis (Bt) cotton is being planted in saline-alkaline soil in China. The Bt protein level in transgenic cotton plants and its control efficiency can be affected by abiotic stress, including high temperature, water deficiency and other factors. However, how soil salinity affects the expression of Bt protein, thus influencing the...

Identification of Aphis gossypii Glover (Hemiptera: Aphididae) Biotypes from Different Host Plants in North China

Background The cotton-melon aphid, Aphis gossypii Glover (Hemiptera: Aphididae), is a polyphagous species with a worldwide distribution and a variety of biotypes. North China is a traditional agricultural area with abundant winter and summer hosts of A. gossypii. While the life cycles of A. gossypii on different plants have been well studied, those of the biotypes of North China...

The Distribution and Host Shifts of Cotton-Melon Aphids in Northern China

Aphis gossypii Glover (Hemiptera: Aphididae) is a serious pest of cotton in northern China. A microsatellite analysis was used to characterize the genetic structure of A. gossypii populations from different geographic, host plant, and seasonal populations in 2014. Among 906 individuals, 507 multilocus genotypes were identified, with genotypic richness values of 0.07–1.00 for the...

The Historical Development of Deqi Concept from Classics of Traditional Chinese Medicine to Modern Research: Exploitation of the Connotation of Deqi in Chinese Medicine

Diagnostic Value of sTREM-1 in Bronchoalveolar Lavage Fluid in ICU Patients With Bacterial Lung Infections: A Bivariate Meta-Analysis

Background The serum soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) is a useful biomarker in differentiating bacterial infections from others. However, the diagnostic value of sTREM-1 in bronchoalveolar lavage fluid (BALF) in lung infections has not been well established. We performed a meta-analysis to assess the accuracy of sTREM-1 in BALF for diagnosis of...

A Comparison of Loop-Mediated Isothermal Amplification (LAMP) with Other Surveillance Tools for Echinococcus granulosus Diagnosis in Canine Definitive Hosts

Background Cystic echinococcosis is highly prevalent in northwest China. A cost-effective, easy to operate diagnostic tool with high sensitivity and specificity would greatly facilitate the monitoring of Echinococcus infections in canine definitive hosts. Methods The primers used in the LAMP assay were based on the mitochondrial nad5 gene of E. granulosus sensu stricto (E...

A protein–protein docking algorithm dependent on the type of complexes

An efficient ‘soft docking’ algorithm is described to assist the prediction of protein–protein association using three-dimensional structures of molecules. The basic tools are the ‘simplified protein’ model and the docking algorithm of Wodak and Janin. The side chain flexibility of Arg, Lys, Asp, Glu and Met residues at the protein surface is taken into account. The complex type...

A fast empirical approach to binding free energy calculations based on protein interface information

Three useful variables from the interfaces of 20 protein–protein complexes were investigated. These variables are the side-chain accessible number (Nb), the number of hydrophilic pairs (Npair) and buried apolar solventaccessible surface areas (ΔΔASAapol). An empirical model based on the three variables was developed to describe the free energy of protein associations. As the...
