objective: adipocyte and skeletal muscle are important tissues which contribute the development and progression of metabolic disorder. insulin has a major regulatory function on glucose metabolism in these tissues by redistributing glucose transporter (glut4) from intracellular vesicles to the cell surface. today, due to the side effects of chemical medications attendance to herbal medicines is...

introduction: cryptorchidism has been proved to cause apoptosis in germ cells in respond to changes in the stimulation levels of specific physiological events. the purpose of this study was to determine whether treatment of bilateral cryptorchidism was associated with alterations in testicular gene expression. methods: to induce bilateral cryptorchid model, immature mice were anesthetized and a...

background: taq dna polymerase is a very important enzyme for molecular biological studies such as dna amplification and dna sequencing by the pcr. it is a standard enzyme that is used in 90% of molecular biology labs today. the aim of this study was to produce taq dna polymerase enzyme in e. coli by a reliable, practical, simple and low cost method.materials and methods: in this study, the taq...

Gradients and subgradients are central to optimization sensitivity analysis of buffered failure probabilities. We furnish a characterization based on subdifferential calculus in the case finite probability distributions and, under additional assumptions, also gradient expression for general distributions. Several examples illustrate application results, especially context optimality conditions.

Background Microalgae are becoming a viable model for the expression of recombinant proteins. However, suitable levels of expression for commercial production have not yet been obtained. One way to increase the heterologous protein production is the codon optimization of the target gene so that it presents the preferential codons used by the host organism according to its own pool of transfer R...

optimization of maintenance resources to maximize the system availability is a major concern in different manufacturing systems. therefore, a lot of effort is put to construct optimization models to reach the maximum availability level and to reduce the costs of lack of availability. however, despite these efforts, data uncertainty in the real world problems was neglected in proposed models whi...
