KCNQ (Kv7) has emerged as a validated target for the development of novel anti-epileptic drugs. In this paper, a series of novel N-phenylbutanamide derivatives were designed, synthesized and evaluated as KCNQ openers for the treatment of epilepsy. These compounds were evaluated for their KCNQ op...

(±)-A80915G, a member of the napyradiomycin family of antibiotics, has been synthesized from 1-amino-2,5-dimethoxy-4-nitrobenzene via the sequential palladium-catalyzed cross-coupling reactions (the Stille reaction) of aryl halides with allyltins and the Diels-Alder reaction of the chloroquinon...

A novel fluorescence detection method based on competitive immunoassay and magnetic bioseparation technique was developed and applied to the determination of pig immunoglobulin G (IgG) in serum samples. Core-shell structured Fe3O4@SiO2 nanoparticles were synthesized by chemical coprecipitation, ...

Rabbit-antihuman Immunoglobulin G (IgG) was immobilized on a gold electrode by electrochemical polymerization with pyrrole. An efficient immunoassay strategy for human IgG determined in human serum was developed based on the specific immunological reaction between the rabbit-antihuman IgG, human...

Antibody drugs have been important therapeutic agents for treating various diseases, such as cancer, rheumatism, and hypercholesterolemia, for the last three decades. Despite showing excellent therapeutic efficacy with good safety in vivo, they require high doses. We have developed a ∼30-nm bio...

A novel electron spin resonance (ESR) spectroscopy method for determination of rabbit IgG was presented. Anti-rabbit IgG antibody was bound to Fe3O4 nanoparticles (FeNPs). The FeNPs were used as probe to give ESR signal. After the optimization of the assay, a molar ratio 500:1 of antibody to FeN...

We separated whole IgG, Fab and F(ab')2 fragments from horse plasma. We previously studied the pharmacokinetics of these immunoglobulins and fragments in rabbits and shown that Fab and F(ab')2 pharmacokinetics were well described by a three-exponential kinetics, while IgG and IgG(T) ph...

The repeatable immobilization of molecular recognition elements onto particle surfaces has a strong impact on the outcomes of affinity-based assays. In this work, an automatic method for the immobilization of immunoglobulin G (IgG) onto protein A-Sepharose microbeads was established through the ...

Neonatal Fc receptor (FcRn) is down-regulated in Hashimoto's thyroiditis (HT) thyrocytes and mediates IgG endocytosis in thyrocytes. The serum distribution of IgG subclasses (of TgAb and TPOAb) differs between HT patients and normal individuals. We aimed to explore the direction and regulat...

An immunosensor with low detection limit for detecting human-IgG (IgG, immunoglobulin G) is presented in this work. The sensor was designed using single mode fiber with large core-offset fusion splice based on Mach–Zehnder interferometer (MZI). The refractive index (RI) sensitivity is as high a...

Polyclonal or monoclonal antibodies against rabies virus ribonucleoprotein (RNP) conjugated to fluorescein isothiocyanate (FITC) have been employed for Rabies virus (RABV) antigen detection by the direct fluorescent antibody test (DFA). To date, these biomolecules have been purified by tradition...

It is of paramount importance to be able to accurately quantify surface coverage of antibodies on gold nanoparticles (AuNP) so as to optimise the sensitivity of AuNP-based immunosensors. Herein, we developed a fluorescence-based method to directly quantify rabbit immunoglobulin G (IgG) used as a...

Seabird colonies drastically transform the sites that they inhabit. Although the influence of seabirds on nutrient cycling has been investigated in numerous studies, the effects on trace elements has scarcely been considered. In this study, we determined the total contents of 9 trace elements in...

Shellfish are one of the most common causes of food allergy. Arginine kinase (AK) is known as an important allergen in shellfish. In the present study, AK from crab (Scylla paramamosain) was purified and its crystal structure was determined. A comparison of AK from S. paramamosain to AKs of othe...

An acyclic flexible bis(α-iminopyridine) ligand has been employed for the stabilization of chlorostannyliumylidene and a tin(II) dication. The syntheses involve the abstraction of chloride from the tin dichloride precursor using trimethylsilyl trifluoromethane sulfonate. The apically disposed t...

Inspired by the enormous importance attributed to the biological function of miRNA, we pour our attention into the design and synthesis of four ruthenium(II) complexes and evaluate their applications as miR-185 detection agents by spectroscopic measurements. It was found that all complexes can f...

Highly oriented cubic (100) HfN films were grown on Si (100) substrates by direct current magnetron reactive sputtering of a metallic Hf target in an Ar/N2 gas environment. The influence of N2 flow ratio on the (100) preferred orientation and crystallinity of the HfN films is investigated. X-ray...

Transesterification of poly(bisphenol A carbonate) with caprolactone segments in ethylene terephthalate–caprolactone copolyester was investigated using 1H and 1H–1H nuclear magnetic resonance (NMR) spectroscopy and a model compound. It was found that during annealing process, transesterificati...

Lewis acids such as M(O3SCF3)3 (M = Sc, Yb, La) triflate salts have been used for the first time as catalysts of the hydrolysis reaction of poly-(bisphenol A carbonate) (PC), which is an attractive route to the chemical recycling and valorization of waste PC. In THF, the M(O3SCF3)3 (M = Sc, Yb, ...

This work presents photophysical and nonlinear optical properties of a novel Cd 2,3-[octakis{4-tert-butylphenoxyphthalocyanine}] (CdOtBPPc) and compare them with those of Pb 2,3-[octakis{4-tert-butylphenoxyphthalocyanine}] (PbOtBPPc). For both the CdOtBPPc and PbOtBPPc, third order imaginary sus...
