Age-related changes in melatonin synthesis in rat extrapineal tissues
(Elsevier, 2009-05)
In the search of new therapeutic targets improving the quality of life of elderly, melatonin, “the chemical expression of darkness”, seems to play a remarkable role in aging process possibly due to its antioxidant, ...

Tutte uniqueness of locally grid graphs
(Departamento de Matemáticas CINVESTAV, 2004)
A graph is said to be locally grid if the structure around each of its vertices is a 3 × 3 grid. As a follow up of the research initiated in [4] and [3] we prove that most locally grid graphs are uniquely determined by ...

Asymmetric clock driver for improved power and noise performances
(IEEE Computer Society, 2007)
One of the most important sources of switching noise and power consumption in large VLSI circuits is the clock generation and distribution tree. This paper analyzes how the use of an asymmetric clock can be an ...

The Efficient Functioning of Photosynthesis and Respiration in Synechocystis sp. PCC 6803 Strictly Requires the Presence of either Cytochrome c6 or Plastocyanin
(Elsevier, 2004)
In cyanobacteria, cytochrome c6 and plastocyanin are able to replace each other as redox carriers in the photosynthetic and respiratory electron transport chains with the synthesis of one or another protein being regulated ...

Caprellid assemblages (Crustacea: Amphipoda) in shallow waters invaded by Caulerpa racemosa var. cylindracea from southeastern Spain
(BMC, 2009)
Growth of the invasive algae Caulerpa racemosa var. cylindracea in shallow habitats may inXuence the faunal assemblage composition. We studied its eVects on caprellid assemblages associated with shallow-water habitats ...

The glutathione/glutaredoxin system is essential for arsenate reduction in Synechocystis sp. strain PCC 6803
(American Society for Microbiology, 2009)
Arsenic resistance in Synechocystis sp. strain PCC 6803 is mediated by an operon of three genes in which arsC codes for an arsenate reductase with unique characteristics. Here we describe the identification of two additional ...
