BACKGROUND Myocardial perfusion grade (MPG) is an accepted method of evaluating myocardial perfusion. However, it does not take into the account, the extent of the perfusion. We hypothesized that myocardial blush area times MPG (total blush) would be more accurate than simple MPG, and yield better prognostic information. METHODS About 34 patients were recruited after they had consented to bot...

In this demo we present a prototype of an experimental platform for evaluating item recommendation algorithms. The application domain for our system is that of digital city guides. Our prototype implementation allows the user to explore different algorithms and compare their output. Among the algorithms implemented is MPG, which aims at providing a diverse set of recommendations better aligned ...

The authors propose a method that selects a set of motion probing gradient (MPG) directions, which is adapted for measuring fiber tracts in some specific region of interest (ROI) with smaller number of MPGs. Given a training set of diffusion magnetic resonance (MR) images, the method selects the set of MPG directions by minimizing a cost function, which represents the square errors of the recon...

The DNA base excision repair (BER) pathway is responsible for the repair of alkylation and oxidative DNA damage. The short-patch BER pathway, beginning with the simple glycosylase N-methylpurine DNA glycosylase (MPG), is responsible for the removal of damaged bases such as 3-methyladenine and 1,N(6)-ethenoadenine from the DNA after alkylation or oxidative DNA damage. The resulting apurinic site...

Methylpurine-DNA glycosylases (MPG proteins, 3-methyladenine-DNA glycosylases) excise numerous damaged bases from DNA during the first step of base excision repair. The damaged bases removed by these proteins include those induced by both alkylating agents and/or oxidizing agents. The intrinsic kinetic parameters (k(cat) and K(m)) for the excision of hypoxanthine by the recombinant human MPG pr...

To analyze myelomonocytic differentiation we have used the approach of differential cDNA analysis to isolate novel genes that are preferentially expressed in mature macrophages. Differential screening of a macrophage cDNA library led to the identification of a novel cDNA that showed macrophage lineage- and differentiation stage-specific expression. Transcripts from the gene, which we have terme...

Artificial photosynthesis is the imitation of natural photosynthesis, which promises an efficient way to use solar energy to synthesize organic matters, in which the key step is the coenzyme regeneration (NADH/NADPH). To achieve an efficient regeneration rate, various photocatalysts have been developed, such as g-C3N4 and mesoporous carbon nitride (mpg-C3N4). Generally, efficiency determination...

Chronic kidney disease (CKD) is a risk factor for end-stage renal failure and cardiovascular events. In patients with CKD, anemia is often caused by decreased erythropoietin production relative to hemoglobin levels. As correction of anemia is associated with improved cardiac and renal function and quality of life, erythropoiesis-stimulating agents (ESAs) are standard therapy for anemia in CKD p...
