We review recent progress in the development of electrochemical biosensors based on ferroceneboronic acid (FcBA) and ferrocene (Fc)-modified boronic acids. These compounds can be used to construct electrochemical biosensors because they consist of a binding site (i.e., a boronic acid moiety) and an electrochemically active part (i.e., an Fc residue). By(More)
The macrophage migration inhibitory factor (mif) cDNA and its genome were cloned from small abalone Haliotis diversicolor supertexta. Small abalone mif (samif) was originally identified from an expressed sequence tag (EST) fragment from a normalized cDNA library. It's 5' untranslated region (UTR) was obtained by 5' rapid amplification of cDNA end (RACE)(More)
BACKGROUND Many prospective cohort studies have investigated the association between nut consumption and risk of coronary artery disease (CAD), stroke, hypertension, and type 2 diabetes (T2D). However, results have been inconsistent. OBJECTIVE We aimed to investigate the association between nut consumption and risk of CAD, stroke, hypertension, and T2D.(More)
A large-scale combined ponds-wetland system was applied for advanced treatment of refractory pollutants in petrochemical industrial wastewater. The system was designed to enhance bioactivity and biological diversity, which consisted of anaerobic ponds (APs), facultative ponds (FPs), aerobic pond and wetland. The refractory pollutants in the petrochemical(More)
Despite the fact that, in practice, enhanced biological phosphorus removal (EBPR) is often combined with biological nitrogen removal (BNR), the feasibility of nitrite (an intermediate in BNR) utilization, by denitrifying poly-P accumulating organisms (DPAO) is still unclear. In this study, the effect of nitrite on the EBPR was evaluated by investigating the(More)
Redox reactions of ferricyanide ions, [Fe(CN)6]3-, in polysaccharide thin films that were prepared by layer-by-layer (LbL) deposition on the surface of a gold electrode were studied electrochemically by cyclic voltammetry. LbL films composed of alginic acid (AGA) and carboxymethylcellulose (CMC) were successfully prepared using poly(ethyleneimine) (PEI) and(More)
In China, with fast economic growth, health and nutrition status among the rural population has shown significant improvement in the past decades. On the other hand, burden of non-communicable diseases and prevalence of related risk factors such as overweight and obesity has also increased. Among rural children, the double burden of malnutrition and(More)
Layer-by-layer (LbL) thin films were prepared using an amphoteric copolymer consisting of alternating diallylamine and maleic acid monomer units (PDAMA), and pH-induced decomposition of the films was studied. LbL deposition of poly(styrene sulfonate) (PSS) and PDAMA on a solid surface afforded thin films at pH 3.0, while thin films did not form at pH 8.0.(More)
Multilayer thin films composed of poly(allylamine hydrochloride) (PAH) and carboxymethyl cellulose (CMC) have been prepared on the surface of a gold (Au) disk electrode by a layer-by-layer deposition of PAH and CMC and ferricyanide ions ([Fe(CN)(6)](3-)) were confined in the film. [Fe(CN)(6)](3-) ions can be successfully confined in the films from weakly(More)
This article reviews recent progress in the development of nanomaterial-based electrochemical biosensors for cancer biomarkers. Because of their high electrical conductivity, high affinity to biomolecules, and high surface area-to-weight ratios, nanomaterials, including metal nanoparticles, carbon nanotubes, and graphene, have been used for fabricating(More)
