the purpose of this study is estimate the protection value of gavkhony wetland ecosystem attributes with use of choice experiment approach and conditional logit model. data needed extracted from six different choice experiment questionnaires filled out by 500 random households in isfahan and varzane city. each questionnaire contained 72 hypothetical policies (options), 36 choice sets, 2442 obse...

(2)H quadrupolar line shapes deliver rich information about protein dynamics. A newly designed 3D (2)H-(13)C-(13)C solid-state NMR magic angle spinning (MAS) experiment is presented and demonstrated on the microcrystalline β1 immunoglobulin binding domain of protein G (GB1). The implementation of (2)H-(13)C adiabatic rotor-echo-short-pulse-irradiation cross-polarization (RESPIRATION CP) ensures...

We ran and analyzed a total of eighteen, 10 ns molecular dynamics simulations of two C-terminal beta-hairpins from the B1 domain of Protein G: twelve runs for the last 16 residues and six runs for the last 15 residues, G41-E56 and E42-E56, respectively. Based on their CalphaRMS deviation from the starting structure and the pattern of stabilizing interactions (hydrogen bonds, hydrophobic contact...

Human cytosolic sialidase (Neuraminidase 2, NEU2) catalyzes the removal of terminal sialic acid residues from glycoconjugates. The effect of siastatin B, known as a sialidase inhibitor, has not been evaluated toward human NEU2 yet. We studied the regulation of NEU2 activity by siastatin B in vitro and predicted the interaction in silico. Inhibitory and stabilizing effects of siastatin B were an...

Abstract Study question Does the resveratrol supplementation in human embryo culture medium improve quality and pregnancy outcomes older women? Summary answer Resveratrol significantly improved good rates. These results are thought to be due biological activities of as an antioxidant. What is known already Reproductive aging involves age-related declines ovarian function development capacity. A...

in the GenBank non-redundant DNA database was examined. Two additional cases of ISAba1 associated with distinct ampC alleles were found in accession numbers EU604835 8 and AY325306. 3 In both of them, the IS was again in the same orientation and separated from the ATG initiation codon of ampC by 9 bp. The number of single nucleotide differences between the various ampC alleles is shown in Table...

Cross-neutralising monoclonal antibodies against influenza hemagglutinin (HA) are of considerable interest as both therapeutics and diagnostic tools. We have recently described five different single domain antibodies (nanobodies) which share this cross-neutralising activity and suggest their small size, high stability, and cleft binding properties may present distinct advantages over equivalent...
