Enzymatic pathways involving catechol-O-methyltransferase (COMT) catabolize circulating catecholamines. A G-to-A polymorphism in the fourth exon of the COMT gene results in a valine-to-methionine amino acid substitution at codon 158, which leads to thermolability and low ("L"), as opposed to high ("H"), enzymatic activity. We enrolled 260 patients postbypass surgery to test the hypothesis that ...

the changes in time and location of surface temperature from a water body has an important effect on climate activities, marine biology, sea currents, salinity and other characteristics of the seas and lakes water. traditional measurement of temperature is costly and time consumer due to its dispersion and instability. in recent years the use of satellite technology and remote sensing sciences ...

Alveolar Echinococcosis (AE) caused by the cestode Echinococcus multilocularis, is a severe helminth infection of man, where unrestricted parasite growth will ultimately result in organ failure and fatality. The tissue-infiltrative growth of the larval metacestode and the limited efficacy of available drugs complicate successful intervention in AE; patients often need life-long medication, and ...

Today’s wireless broadband networks are required to provide QoS guarantee as well as fairness to different kinds of traffic. Recent wireless standards (such as LTE and WiMAX) have special provisions at MAC layer for differentiating and scheduling data traffic for achieving QoS. The main focus of this paper is concerned with high speed packet queuing/scheduling at central node such as base stati...

We report the observation of resonant excitation edge photocurrents in bilayer graphene subjected to terahertz radiation and a magnetic field. The resonantly excited photocurrent is observed for both interband (at low carrier densities) intraband high transitions between Landau levels (LL). While LL can be traced classical cyclotron resonance (CR) produce strong features, interband-LL resonance...

Multi-wavelength chlorophyll fluorescence analysis was utilised to examine the photosynthetic efficiency of the biofuel-producing alga Nannochloropsis oculata, grown under two light regimes; low (LL) and high (HL) irradiance levels. Wavelength dependency was evident in the functional absorption cross-section of Photosystem II (σII(λ)), absolute electron transfer rates (ETR(II)), and non-photoch...

Low temperature combined with low light (LL) is an adverse factor seriously affecting pepper productivity and quality. However, little known about the molecular mechanisms related to LL stress responses. Therefore, transcriptome physiological changes in Hangjiao No. 2 (H2) Xiangtela (X2) were studied under normal conditions LL. We found 8,392 8,028 differentially expressed genes H2 X2, respecti...
