This study represent an assessment of the feasibility of using optical and near infra-red wavelengths to map water depth and substrate type which are two of the primary components of river physical habitat. The objective was met by measuring reflectance using field spectroscopy of exposed and then progressively submerged (0–1 m) artificial substrates during rising tides on a tidal reach of the ...

Restriction enzyme (REase) RM.BpuSI can be described as a Type IIS/C/G REase for its cleavage site outside of the recognition sequence (Type IIS), bifunctional polypeptide possessing both methyltransferase (MTase) and endonuclease activities (Type IIC) and endonuclease activity stimulated by S-adenosyl-L-methionine (SAM) (Type IIG). The stimulatory effect of SAM on cleavage activity presents a ...

The irradiation effect of X-ray on the electrical properties Schottky-barrier diode (SBD) and metal-semiconductor field-effect transistors (MESFET) based surface conductivity hydrogen-terminated single-crystal diamond (SCD) epilayers was investigated. Ohmic contact formed by a Pd/Ti/Au multilayer Schottky metal Al thin film for fabrication SBDs MESFETs. performed with dose 100 kGy. It observed ...

Protein neddylation is essential for the viability of most organisms and is widely involved in the regulation of immunity, DNA damage and repair, cell signaling and cell cycle. Unlike RING-type neddylation ligases, HECT-type neddylation ligase remains less defined. Here, we show that Itch is a novel HECT-type neddylation E3 ligase and we identify JunB as a substrate of Nedd8 modification by Itc...

The effect of point defects and interactions with the substrate are shown by density functional theory calculations to be significant importance for structure properties hexagonal boron nitride (h-BN) films on highly ordered pyrolytic graphite (HOPG) Ni(111) substrates. structure, surface chemistry, electronic calculated h-BN systems selected intrinsic, oxygen, carbon graphene hybrid structures...

Cultured rat glomerular epithelial cells (GEC) were examined for their ability to release extracellular matrix-degrading proteinases with [3H]gelatin as substrate. GEC-conditioned media, under serum-free conditions, contained modest amounts of gelatinase activity (1 to 10 U/mg of protein); the activity was maximal at neutral pH, was inhibited by zinc chelators, was not inhibited by tissue inhib...

a mathematical model was developed to predict the effects of wind speed, light, ph, temperature, dissolved carbon dioxide and chemical oxygen demand (cod) on dissolved oxygen (do) in fish ponds. the effects of organic feeds, aeration and fish activity were added to the model developed by kayombo et al. for waste stabilization ponds (ecological modeling 127(2000): 21-31) to reflect the situat...

background: parasite proteases have important roles in cleavage of host proteins during the invasion of host tissues and participate in the parasite’s evasion from the host’s immune response. the aim of the present study was to estimate a metalloproteinase properties of taenia solium metacestode (tsmp) during host-parasite interactions, and evaluate its potential as a serodiagnostic antigen for...
