Background: Phytate is an anti-nutritional factor in plants, which catches the most phosphorus contents and some vital minerals. Therefore, Phytase is added mainly as an additive to the monogastric animals’ foods to hydrolyze phytate and increase absorption of phosphorus. Objectives: Y. intermedia phytase is a new phytase with special characteristics such as high specific activity, pH stabilit...

Standard vectors for high-level expression elicited undetectable levels of the gH and gL glycoproteins of rhesus monkey rhadinovirus (RRV) following transient-transfection assays under a variety of conditions. These same vectors and conditions yielded high levels of RRV gB expression. Unlike other genes of RRV, both the gH and gL genes were noted to have a highly aberrant, suboptimal codon usag...

The axial bodyplan of Drosophila melanogaster is determined during a process called morphogenesis. Shortly after fertilization, maternal bicoid mRNA is translated into Bicoid (Bcd). This protein establishes a spatially graded morphogen distribution along the anterior-posterior (AP) axis of the embryo. Bcd initiates AP axis determination by triggering expression of gap genes that subsequently re...

The regulation of metabolic activity by tuning enzyme expression levels is crucial to sustain cellular growth in changing environments. Metabolic networks are often studied at steady state using constraint-based models and optimization techniques. However, metabolic adaptations driven by changes in gene expression cannot be analyzed by steady state models, as these do not account for temporal c...

Ethylene (C2H4) is a simple alkene of high commercial value due to multitude of large-scale uses in plastic industry, and as a potential fuel for spark-ignition piston engines. Currently ethylene is derived entirely from non-renewable sources, but it can also be produced directly from atmospheric CO2 via microbial biosynthesis in photosynthetic cyanobacterial hosts by the expression of ethylene...

Automatic facial expression recognition plays an important role in various application domains such as medical imaging, surveillance and human-robot interaction. This research presents a novel facial expression recognition system with modified Local Binary Patterns (LBP) for feature extraction and a modified firefly algorithm (FA) for feature optimization. First, in order to deal with illuminat...

Gene expression data play an important role in the development of efficient cancer diagnoses and classification. The genes identified are subsequently used to classify independent test set samples. The different feature selection methods are investigated and most frequent features are selected among all methods. This paper provides gene selection strategies for multiclass classification that ca...

BACKGROUND The nisin-controlled gene expression system NICE of Lactococcus lactis is one of the most widely used expression systems in Gram-positive bacteria. Despite its widespread use, no optimization of the culture conditions and nisin induction has been carried out to obtain maximum yields. As a model system induced production of lysostaphin, an antibacterial protein (mainly against Staphyl...

Our algorithm combines the Reverse Polish Notation (RPN) and expression tree algorithms it is a novel method for efficiently evaluating arithmetic expressions. The benefits of Expression Trees to provide practical efficient solution expressions in both infix postfix notation. first converts notation RPN, which then used construct an tree. evaluated using recursive function that traverses perfor...

a:4:{s:10:"Background";s:897:"Human luteinizing hormone (hLH) belongs to glycoprotein hormones which is composed of two non-covalently linked subunit, α and β. The α-subunit is similar in all glycoprotein hormones, whereas the β-subunit is conferring the hormonal specificity. This hormone has important roles in the growth and maturity of sexual organs and secondary sexual characteristics and st...
