We report a systematic study of Si|ZnO and Si|ZnO| metal photocathodes for effective photoelectrochemical cells and hydrogen generation. Both ZnO nanocrystalline thin films and vertical nanowire arrays were studied. Si|ZnO electrodes showed increased cathodic photocurrents due to improved charge separation by the formation of a p/n junction, and Si|ZnO:Al (n(+)-ZnO) ...

This paper demonstrates how discrete-time models describing population dynamics of two competing species can be derived in a bottom-up manner by considering competition for resources among individuals and the spatial distribution of individuals. The competition type of each species is assumed to be either scramble, contest, or an intermediate between ...

Caco-2 cell metallothionein (MT) formation was studied to determine if MT could be used as a proxy for zinc (Zn) absorption in a cell culture model. The MT intracellular concentration was determined using a cadmium/hemoglobin affinity assay. The cellular Zn uptake was determined by acid digests (5% HNO(3)) using inductively-coupled ...

A growing body of evidence has suggested that the use of angiotensin II (Ang II) type 1 (AT(1)) receptor blockers (ARBs) leads to a significant decrease in mortality and morbidity in patients with congestive heart failure. The AT(1) receptor is a seven-transmembrane G protein-coupled receptor, and is involved in regulating ...

In this study, we develop an efficient method for multiple DNA detection by exploring silver nanoclusters (AgNCs)-graphene oxide (GO) nanohybrid materials. Because of the extraordinarily high quenching efficiency of GO, the ssDNA-AgNCs probe exhibits minimal background fluorescence, while strong emission is observed when it forms a double helix with the ...

Hamate osteoarticular autografts are difficult to obtain and it is unclear to what degree the graft matches the joint surface to be replaced and whether a direct ulnar approach might provide a more reliable graft than the standard proximal to distal approach. We modeled hemihamate osteotomies using quantitative three-dimensional CT ...

Centromere mapping is a powerful tool for improving linkage maps, investigating crossover events, and understanding chiasma interference during meiosis. Ninety microsatellite markers selected across all linkage groups (LGs) from a previous Chlamys farreri genetic map were studied in three artificially induced meiogynogenetic families for centromere mapping by half-tetrad analysis. Inheritance ...

Endogenous S-nitrosylation of proteins, a principal mechanism of cellular signaling in eukaryotes, has not been observed in microbes. We report that protein S-nitrosylation is an obligate concomitant of anaerobic respiration on nitrate in Escherichia coli. Endogenous S-nitrosylation during anaerobic respiration is controlled by the transcription factor OxyR, previously thought to ...

Circumventricular organs (CVOs) are specialized ventricular structures around the third and fourth ventricles of the brain. In humans, these structures are present during the fetal period and some become vestigial after birth. Some of these organs, such as the pineal gland (PG), subcommissural organ (SCO), and organum vasculosum of the ...

One of the main limitations for achieving truly lab-on-a-chip (LOC) devices for point-of-care diagnosis is the incorporation of the "on-chip" detection. Indeed, most of the state-of-the-art LOC devices usually require complex read-out instrumentation, losing the main advantages of portability and simplicity. In this context, we present our last advances towards ...

Cancer cells are characterized by rapid proliferation and require adaptive metabolic responses to allow continued biosynthesis and cell growth in the setting of decreased oxygen (O(2)) and nutrient availability. The hypoxia-inducible factors (HIFs) are a common link between adaptation to low O(2), changes in cancer metabolism, and malignant progression. The ...

Kaschube et al. (Reports, 19 November 2010, p. 1113) argue that pinwheel density in three mammalian species follows a universal constant of π as predicted by their orientation-selective suppressive long-range connectivity model. We dispute their conclusions and suggest that a simple brain size-pinwheel density scaling law suffices in predicting the ...

Malaria remains a global health problem affecting more than 515 million people all over the world including Malaysia. It is on the rise, even within unknown regions that previous to this were free of malaria. Although malaria eradication programs carried out by vector control programs are still effective, anti-malarial drugs ...

Fundamental thermodynamics and climate models suggest that dry regions will become drier and wet regions will become wetter in response to warming. Efforts to detect this long-term response in sparse surface observations of rainfall and evaporation remain ambiguous. We show that ocean salinity patterns express an identifiable fingerprint of an ...

PURPOSE: Most multidimensional patient-reported outcomes (PRO) measures are lengthy to complete. Computerized adaptive testing (CAT) that selects the most informative items can potentially reduce respondent burden without sacrificing measurement accuracy. The commonly used maximum Fisher information item selection method has been reported to lead to highly unbalanced item bank usage ...

We utilize classical molecular dynamics to study the quality (Q)-factors of monolayer CVD-grown graphene nanoresonators. In particular, we focus on the effects of intrinsic grain boundaries of different orientations, which result from the CVD growth process, on the Q-factors. For a range of misorientation angles that are consistent with those ...

The three-coordinate Ni(i) complex Ni(Cl)(P(2)), where P(2) is the diphosphine (iPr)DPDBFphos, reacts with the acids HCl·(dioxane) and 2,6-lutidinium chloride to generate Ni(H)(Cl)(P(2)) and Ni(Cl)(2)(P(2)). Photolysis of the Ni(H)(X)(P(2)) (for X = Cl, Br) results in formation of H(2) and the Ni(i) halide. This reaction also proceeds in reverse when heated.
