BiVO(4) and many other semiconductor materials are ideal visible light responsive semiconductors, but are insufficient for overall water splitting. Upon loading water oxidation cocatalyst, for example Co-borate (denoted as CoB(i)) used here, onto BiVO(4) photoanode, it is found that not only the onset potential is negatively shifted but also the ...

Prior studies disclosed that Aeromonas hydrophila NIU01 was a biodecolorization and bioelectricity bacterium which was isolated from a cross-strait of Taiwan. However, enzymatic function, laccase, involved in this strain had never been reported. This first attempt is to explore its laccase activity, the molecular cloning and heterologous recombinant expression in ...

The asymmetric synthesis of 3-indolylglycine derivatives was achieved by an oxidative heterocoupling reaction. This method for the selective C-3 functionalization of unprotected indoles with the chiral equivalent of a nucleophilic glycine nickel(ii) complex afforded adducts with high diastereoselectivities. The decomposition of adducts readily afforded 3-indolylglycine derivatives in high yields.

Evidence of an autocatalytic radical chain pathway has been reported in formation of a non-heme iron(iv)-oxo complex by oxidation of an iron(ii) complex with dioxygen and isopropanol in acetonitrile at 298 K. The radical chain reaction is initiated by hydrogen abstraction from isopropanol by the iron(iv)-oxo complex.

The volatile anesthetic isoflurane protects against renal ischemia and reperfusion injury by releasing renal tubular TGF-β1. As adenosine is a powerful cytoprotective molecule, we tested whether TGF-β1 generated by isoflurane induces renal tubular ecto-5'-nucleotidase (CD73) and adenosine to protect against renal ischemia and reperfusion injury. Isoflurane induced new CD73 synthesis ...

Apurinic/apyrimidinic (AP) sites are common DNA lesions arising from spontaneous hydrolysis of the N-glycosidic bond and base-excision repair mechanisms of the modified bases. Due to the strong association of AP site formation with physically/chemically induced DNA damage, quantifying AP sites provides important information for risk assessment of exposure to genotoxins ...

BACKGROUND: It is unclear whether late THA dislocations are related to mechanical impingement or to a biological mechanism that decreases the stability provided by the capsule (eg, inflammation secondary to osteolysis). It is also unknown if alumina-on-alumina bearing couples decrease the risk of late dislocation as a result of the ...

BACKGROUND: Dislocation continues to commonly cause failure after primary and revision total hip arthroplasty (THA). Fully constrained liners intended to prevent dislocation are nonetheless associated with a substantial incidence of failure by redislocation, mechanical failure, aseptic loosening, or a combination. Constrained liners with cutouts of the elevated rims can theoretically ...

Recent gene expression data suggest that the region on which the onychophoran antenna is situated corresponds to the anteriormost, apparently appendage-less region of the arthropod head. The fate of the onychophoran antenna (or any appendage-like precursor), also called the primary antenna, has been discussed intensively, and there are conflicting suggestions ...

The TRAMP (Transgenic Adenocarcinoma of the Mouse Prostate) and LADY (Probasin-large T antigen transgenic mouse) mice are widely used autochthonous models of prostate cancer. Both models utilise probasin promoters to direct androgen-regulated expression of oncogenic SV40 specifically to epithelial cells of the mouse prostate. The oncogenic processes and phenotypes which ...

Superiority of the left upper limb in proprioception tasks performed by right-handed individuals has been attributed to better utilization of proprioceptive information by a non-preferred arm/hemisphere system. However, it is undetermined whether this holds for multiple upper and lower limb joints. Accordingly, the present study tested active movement proprioception at ...

Tandem CCCH Zinc Finger proteins (TZFs) are post-transcriptional regulators of gene expression in animals and yeast. Genetic studies indicate that plant TZFs are involved in hormone mediated developmental and environmental responses. We have demonstrated previously that Arabidopsis AtTZF1 can localize to Processing Bodies (PBs) and Stress Granules (SGs), and affects ...

A supramolecular strategy has been applied to construct two tetranuclear lanthanide complexes for investigating the magnetic properties of individual lanthanide ions. The Ln(III) complexes (Ln = Dy, Tb) display field-induced slow magnetization relaxation, typical of single-molecule magnet behavior. The four lanthanide ions in the molecules are well separated by distances ...

The ascomycetous yeast Yarrowia lipolytica has been established as model system for studies of several research topics as well as for biotechnological processes in the last two decades. However, frequency of heterologous recombination is high in this yeast species, and so knockouts of genes are laborious to achieve. Therefore, the ...

One of the major concerns of the general public about transgenic crops relates to the mixing of genetic materials between species that cannot hybridize by natural means. To meet this concern, the two transformation concepts cisgenesis and intragenesis were developed as alternatives to transgenesis. Both concepts imply that plants must ...

BACKGROUND: Placement of ureteral stents at the time of renal transplantation is thought to decrease the incidence of postoperative complications, such as anastomotic leakage and stenosis. However, stents may also predispose to post-transplantation urinary tract infection, which can lead to increased risks of graft dysfunction, sepsis, and death. The aim ...

Electronic and internet-based tools for patient-provider communication are becoming the standard of care, but disparities exist in their adoption among patients. The reasons for these disparities are unclear, and few studies have looked at the potential communication technologies have to benefit vulnerable patient populations. To characterize access to, interest in, ...

Bacterial nitric oxide reductase (NOR) is a major source of the powerful greenhouse gas N2O. NorBC from Paracoccus denitrificans is a heterodimeric multi-heme transmembrane complex. The active site, in NorB, comprises high-spin heme b3 in close proximity to non-heme iron, FeB. In oxidised NorBC, the active-site is EPR-silent due to ...

Traumatic posterior hip dislocation in adults is generally understood to be the result of a high-energy trauma. Aside from reduced femoral antetorsion, morphologic risk factors for dislocation are unknown. We previously noticed that some hips with traumatic posterior dislocations had evidence of morphologic features of femoroacetabular impingement (FAI), therefore, we ...

AIMS: Ubiquilin-1 acts as an adaptor protein that mediates the translocation of polyubiquitinated proteins to the proteasome for degradation. Although previous studies suggested a key role of ubiquilin-1 in the pathogenesis of Alzheimer's disease (AD), a direct relationship between ubiquilin-1 and Hirano bodies in AD brains remains unknown. METHODS: By ...
