(WILEY-V C H VERLAG GMBH, 2007-02-11)Glycogen synthase catalyzes the incorporation of UDP-glucose into glycogen. The activity of the enzyme is usually measured either by a spectrophotometric method or by a radioassay. The first one is not suitable because ...
-
(Elsevier B.V., 2007-01-22)Abstract Besides the classic direct route, frog oocytes incorporate glucosyl units into glycogen by the so-called indirect pathway. The operation of both pathways depends on glucose availability. Below 0.5 mM glucose ...
-
(RESILIENCE ALLIANCE, 2008-12)The biocultural conservation and research initiative of Omora Ethnobotanical Park and the UNESCO Cape Horn Biosphere Reserve was born in a remote part of South America and has rapidly expanded to attain regional, national, ...

Alemtuzumab Induction in Kidney Transplantation: Clinical Results and Impact on T-Regulatory Cells (ELSEVIER SCIENCE INC, 2008-11)Alemtuzumab (ALT), a humanized monoclonal anti-CD52 antibody, was introduced in solid organ transplantation as an induction agent. ALT associated with anticalcineurins has provided a low incidence of acute rejection ...
-
(WILEY-V C H VERLAG GMBH, 2008-05-16)The yeast Xanthophyllomyces dendrorhous is biotechnologically important due to its ability to produce the pigment astaxanthin, but is poorly understood at the genetic level. This is mainly because its preservation is ...

Formation of posterior cranial placode derivatives requires the Iroquois transcription factor irx4a (ACADEMIC PRESS INC ELSEVIER SCIENCE, 2008-12-06)Members of the Iroquois (Irx) homeodomain transcription factor gene family have been implicated in a variety of early developmental processes, including neural pre-patterning, tissue differentiation, neural crest development ...
-
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2007-12-11)The Hedgehog (Hh) signaling pathway plays critical instructional roles during embryonic development. Misregulation of Hh/Gli signaling is a major causative factor in human congenital disorders and in a variety of cancers. ...
-
(PUBLIC LIBRARY SCIENCE, 2009-04-17)In humans, the absence or irreversible loss of hair cells, the sensory mechanoreceptors in the cochlea, accounts for a large majority of acquired and congenital hearing disorders. In the auditory and vestibular neuroepithelia ...
-
(BLACKWELL, 2007-09-03)Olfactory sensory neurons respond to odorants increasing Ca2+ concentrations in their chemosensory cilia. Calcium enters the cilia through cAMP-gated channels, activating Ca2+-dependent chloride or potassium channels. ...
-
(CELL PRESS, 2005-07-07)During regional patterning of the anterior neural plate, a medially positioned domain of cells is specified to adopt retinal identity. These eye field cells remain coherent as they undergo morphogenetic events distinct ...
-
(BLACKWELL, 2007-03-20)The polychlorinated biphenyl (PCB)-degrading Pseudomonas sp. B4 was tested for its motility and ability to sense and respond to biphenyl, its chloroderivatives and chlorobenzoates in chemotaxis assays. Pseudomonas sp. ...
-
(SOC GENERAL MICROBIOLOGY, 2006-09-14)Altered starch accumulation is a characteristic biochemical symptom of virus infection in plants. To assess its biological importance, infection of Arabidopsis thaliana with Turnip vein-clearing virus, Cucumber mosaic ...
-
(AMER SOC BIOCHEMISTRY MOLECULAR BIOLOGY INC, 2007-10-02)Acidithiobacillus ferrooxidans is a chemolithoautotrophic acidophile capable of obtaining energy by oxidizing ferrous iron or sulfur compounds such as metal sulfides. Some of the proteins involved in these oxidations ...
-
(Elsevier B.V., 2006-08-15)Hypoxia-inducible factors (HIFs) regulate gene expression in response to hypoxia and in vertebrates they are known to participate in several developmental processes, including angiogenesis, vasculogenesis, heart and central ...
-
(COLD SPRING HARBOR LAB PRESS, 2010-05-25)Recent studies of the genome architecture of vertebrates have uncovered two unforeseen aspects of its organization. First, large regions of the genome, called gene deserts, are devoid of protein-coding sequences and have ...
-
The Irx gene family in zebrafish: genomic structure, evolution and initial characterization of irx5b (SPRINGER, 2004-04-03)Genes of the iroquois (Iro/Irx) family are highly conserved from Drosophila to mammals and they have been implicated in a number of developmental processes. In flies, the Iro genes participate in patterning events in ...
-
(COMPANY OF BIOLOGISTS LTD, 2007-08-29)The Snail genes are implicated in processes that involve cell movement, both during embryonic development and tumour progression. In teleosts, the vertebrate Snail1 gene is represented by two distinct genes, snail1a and ...
-
(WILEY-LISS, 2007-03-20)Striking conservation in various organisms suggests that cellular nucleic acid binding protein (CNBP) plays a fundamental biological role across different species. Recently, it was reported that CNBP is required for ...
-
(ELSEVIER GMBH, 2005-09-02)Dendritic cells (DCs) are the only professional antigen-presenting cells endowed with the ability to stimulate naı¨ve T cells and initiate a primary immune response. For this reason, DC-based immunization has been shown ...
-
(Pontificia Universidad Católica de Chile, 2006-01-02)Viruses that infect plants are generally single-stranded (ss) positive-sense RNA viruses. The accumulation of the virus progeny inside the plant cells involves translation, replication, cell–to-cell and long-distance ...
