Antimony doped tin dioxide nanometer powders have been prepared by the hydrothermal method using SbCl3 as the source of antimony. The doped powders are examined by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The crystal phase composition, particle size, crystal appearance...

Here, we developed one kind of novel TiO2 ceramics with colossal dielectric constant by chemical modifications (Bi3+ and Sb5+), and discussed the physical origin for giant dielectric constant. Effects of Bi and/or Sb on their microstructure, dielectric properties as well as its frequency and tem...

The development of cost-effective In2O3-based sensors exhibiting high sensitivity and selectivity to NO2 at low temperature is still a challenge. For the first time, Sb2O3 modified porous In2O3 hexagonal nanotubes (Sb2O3/In2O3 HNTs) have been synthesized for highly efficient NO2 sensing. Texture...

A significant amount of antimony (Sb) enters into the environment every year because of the wide use of Sb compounds in industry and agriculture. The exposure to Sb, either direct consumption of Sb or indirectly, may be fatal to the human health because both antimony and antimonide are toxic. Fi...

In this work, a novel electrocatalytic filtration membrane with high degradation efficiency and low cost was fabricated by coating nano antimony-doped tin dioxide (Sb-SnO2) on a porous coal-based carbon membrane (CM) through sol-gel method. The nano Sb-SnO2 is homogeneously distributed on the CM...

Antimony-doped tin dioxide(ATO) nanoparticles with primary diameter in the range of 9–10 nm were rapidly synthesized via a novel combustion technique, starting with antimony trichloride and tin tetrachloride as metal sources and self-assembly compounds as fuels. The combustion phenomena and cha...

Manganese (Mn) and antimony (Sb) co-doping tin dioxide (SnO2) electrodes with low impedance and high electrochemical stability were successfully fabricated by coating pyrolysis method. The electrodes were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), linear sweep ...

Titanium dioxide (TiO2) has been widely used as the white pigment in paintings and coatings. It is of significance to endow TiO2 powders with the high conductivity to extend its application. In this research, rutile TiO2 nanorods were prepared as the substrate material. Further the surface coati...

In this study, we developed a simple, sensitive and label-free colorimetric sensor for trypsin and its inhibitor using oxidase mimicking activity of protamine-stabilized platinum nanoparticles units (Pro-PtNPs units). Protamine is designed to stabilize PtNPs and served as the substrate of trypsi...

Conjugation of trypsin and trypsin inhibitor with milk beta-lactoglobulin (b-LG) was studied in aqueous solution at physiological pH. Multiple spectroscopic methods and transmission electron microscopy (TEM) were used to characterize protein–protein interactions and protein morphology. Thermody...

To establish successful infections, endoparasitoid wasps must develop strategies to evade immune responses of the host. Here, we identified and characterized a teratocytes-expressed gene encoding a trypsin inhibitor-like protein containing a cysteine-rich domain from Cotesia vestalis, CvT-TIL. C...

Cassia leiandra is an Amazonian plant species that is used popularly for the treatment of mycoses. Recently, a protease inhibitor, named ClTI, with insecticidal activity against Aedes aegypti, was purified from the mature seeds of C. leiandra. In this work, we show that ClTI has antifungal activ...

BackgroundSoybeans are an essential source of low cost protein. They are widely consumed due to their functionality and nutritive value. Recently, the consumption of soybeans has been increasing due to its beneficial effects on human health such as prevention and treatment of various chronic ill...

Proline-based trypsin inhibitors occupying the S1–S2–S1′ region were identified by an HTS screening campaign. It was discovered that truncation of the P1′ moiety and appropriate extension into the S4 region led to highly potent trypsin inhibitors with excellent selectivity against related se...

Chitosan-protein conjugates are widely used in therapeutic drug delivery. We report the bindings of chitosan nanoparticles with trypsin (try) and trypsin inhibitor (tryi), using thermodynamic analysis and multiple spectroscopic methods. Thermodynamic parameters ΔS, ΔH and ΔG showed chitosan-p...

Most herbs of traditional Chinese medicine (TCM) are used as air-dried decoction pieces that are manufactured and kept at ambient temperature for long periods. Given the ability of some desiccation-tolerant plants to conserve RNA, it could be worthwhile to isolate mRNA from TCM decoction pieces ...

In this work, films produced by blending cashew gum polysaccharide (CGP) with PVA were used as support for immobilization of trypsin inhibitors with antimicrobial activity obtained from Platypodium elegans (PeTI) and Inga laurina (ILTI). The produced films had a homogeneous macroscopic surface w...

Al cation may trigger protein structural changes such as aggregation and fibrillation, causing neurodegenerative diseases. We report the effect of Al cation on the solution structures of trypsin (try) and trypsin inhibitor (tryi), using thermodynamic analysis, UV–Visible, Fourier transform infr...

In the present study, Xenopus nerve–muscle cultures were used to explore the functional roles of A chain (a phospholipase A2 subunit) and B chain (a non-phospholipase A2 subunit) of Bungarus multicinctus β-bungarotoxin. It was found that β-bungarotoxin induced an increment of the frequency of...

Using B1 chain of β-bungarotoxin (β-Bgt) as bait in yeast two-hybrid screen, we found that KChIP3 was a binding protein of B1 chain. Thus, protein–protein interaction between β-Bgt and KChIP3 is investigated in the present study. Pull-down assay showed that recombinant KChIP3 proteins were a...
