This communication reports a novel enzymatic Ag-deposition scheme combined with chemical-chemical redox cycling by reduced β-nicotinamide adenine dinucleotide. This novel scheme allows a higher Ag-deposition rate than a scheme using only enzymatic Ag deposition. Therefore, it can be applied for the highly sensitive detection of a cardiac biomarker, creatine kinase-MB.

the calling behavior of virgin carob moth females, ectomyelois ceratoniae (zeller) (lep.: pyralidae) was evaluated under two different thermal regimes, cycling and constant temperatures under laboratory condition. the period of calling activity under cycling temperature was prolonged and the total period of calling activity of an individual female was increased. although moths maintained under ...

interrupting the processes which control ecosystem resources has dramatic impacts on the rangeland conditions. to protect ecosystems and landscape, it needs to understand the ecosystem processes which regulate the ecosystem resources. as main components of ecosystems, patches and inter-patches play important roles in energy and materials cascade. ecologically, functional parameters such as stab...

A survey of the literature indicates that several chemicals whose reduced metabolites are capable of undergoing redox cycling in biological systems also possess significant teratogenic properties when tested in vivo. We have initiated investigations to determine whether the embryotoxic effects of such chemicals could result from their redox cycling properties and whether redox cycling could be ...

Understanding the evolution of chemical composition and morphology of battery materials during electrochemical cycling is fundamental to extending battery cycle life and ensuring safety. This is particularly true for the much debated high energy density (high voltage) lithium-manganese rich cathode material of composition Li(1 + x)M(1 - x)O2 (M = Mn, Co, Ni). In this study we combine full-field...

the present study was conducted on buffaloes that were non-cycling (heifers, n=32; lactating, n=13) or cycling (heifers, n=11; lactating, n=27) and in the buffaloes that conceived (heifers; n=11; lactating, n=23)or failed to conceive (heifers, n=32; lactating, n=17) subsequent to artificial insemination. plasma samples were analyzed for thyroid stimulating hormone, thyroid hormones, glucose, to...
