Protein disulfide bond formation is catalyzed by a series of Dsb enzymes present in the periplasm of Escherichia coli. The crystal structure of the DsbB-DsbA-ubiquinone ternary complex provided important insights into mechanisms of the de novo disulfide bond generation cooperated by DsbB and ubiquinone and of the disulfide bond shuttle from DsbB to DsbA. The structural basis for prevention of t...

It appears that the expression of vascular endothelial growth factor (VEGF) is increased during brain injury and thus may contribute to disruption of the blood-brain barrier (BBB) during cerebrovascular trauma. The first goal of this study was to determine the effect of VEGF on permeability of the BBB in vivo. The second goal was to determine possible cellular mechanisms by which VEGF increases...

Content-based image retrieval (CBIR) is the task of finding images in a database that are most similar to input query based on its visual characteristics. Several methods from state art (bag words, VLAD, etc.) or recent deep leaning try solve CBIR problem. In particular, learning new field and used for several vision applications including CBIR. But, even with increase performance algorithms, t...

Muscle synaptogenesis in Drosophila melanogaster requires endocytosis of Commissureless (Comm), a binding partner for the ubiquitin ligase dNedd4. We investigated whether dNedd4 and ubiquitination mediate this process. Here we show that Comm is expressed in intracellular vesicles in the muscle, whereas Comm bearing mutations in the two PY motifs (L/PPXY) responsible for dNedd4 binding [Comm(2PY...

A CO2 solid sorbent based on polyethyleneimine 10k (PEI-10k) impregnated into mesoporous silica (MPS) foam was synthesized and utilized to capture CO2 at temperatures ranged from 65 ̊C to 95 ̊C. The calculated nitrogen and carbon contents in the bulk of the PEI-10k/MPS sorbent were similar to the XPS results measured on the surface of the foam, suggesting that the PEI was homogeneously distribute...

Muñoz-Pérez I, Moreno-Pérez D, Cardona-González C, Esteve-Lanao J. Prediction of race pace in long distance running from blood lactate concentration around race pace. J. Hum. Sport Exerc. Vol. 7, No. 4, pp. 763-769, 2012. The aim of this study was to develop an equation for predicting the performance in 10 kilometers road race (10k), Half Marathon (21k) and Marathon (42k), using the blood lacta...

We revisit the evaporation process of gas from dwarf galaxies after it has been photo-ionized by the UV flux from the first stars and AGNs and heated to T ≃ 10 or 2 × 10K respectively. Earlier estimates, based on the balance between pressure and gravity, indicated that dark haloes of virial velocity lower than Vevap ≃ 11−13 kms −1 have lost most of their gas in a dynamical time. We follow the c...

in this study, a new and valuable forage source was introduced with combination and silage of alfa-alfa, halocnemum and mesquite via chemical, gas production and in vivo methods. to perform this research, first the right amounts of the species were collected. then they were cut by chopper to the dimensions of less than 5 cm. then, halocnemum, mesquite fruit, alfalfa and molasses were silaged ac...
