Planta . 2013 Nov; 165(3):348-53. PMID: 24241139
Synchronous cultures of the colorless chlorophyte Prototheca zopfii Kruger were obtained by a shift-down of the basal medium plus addition of 1.5 mM ethylenediaminetetracetic acid for a 10-14-h period, followed...

Puente-Sanchez F, Moreno-Paz M, Rivas L, Cruz-Gil P, Garcia-Villadangos M, Gomez M, et al.
Geobiology . 2013 Nov; 12(1):34-47. PMID: 24237661
The Iberian Pyrite Belt (IPB, southwest of Spain), the largest known massive sulfide deposit, fuels a rich chemolithotrophic microbial community in the Río Tinto area. However, the geomicrobiology of its...

Kobayashi K, Ehrlich S, Albertini A, Amati G, Andersen K, Arnaud M, et al.
Proc Natl Acad Sci U S A . 2003 Apr; 100(8):4678-83. PMID: 12682299
To estimate the minimal gene set required to sustain bacterial life in nutritious conditions, we carried out a systematic inactivation of Bacillus subtilis genes. Among approximately 4,100 genes of the...

Arch Microbiol . 2001 Nov; 176(5):377-80. PMID: 11702080
Type I signal peptidases are responsible for the proteolytic cleavage of the signal peptide of secreted proteins. In the gram-positive bacterium Streptomyces lividans, four adjacent genes (sipW, sipX, sipY and...

Fishman J, Nunez Jr D, Kane A, Rivas L, Jacobs W
AJR Am J Roentgenol . 1999 Dec; 172(4):1027-31. PMID: 10587141
Objective: The purpose of this study was to evaluate the relative value of and interobserver agreement on direct versus indirect (hematoma) signs of traumatic aortic injury using helical CT. Materials...

Nunez Jr D, Zuluaga A, Rivas L, Becerra J
Radiographics . 1996 Nov; 16(6):1307-18; discussion 1318-21. PMID: 8946537
Assessment of suspected cervical spine injuries remains a major debate in trauma care. It is generally accepted that many fractures are missed or incompletely shown at radiography, mainly because of...

Marti H, Wenger R, Rivas L, Straumann U, Digicaylioglu M, Henn V, et al.
Eur J Neurosci . 1996 Apr; 8(4):666-76. PMID: 9081618
The haematopoietic growth factor erythropoietin is the primary regulator of mammalian erythropoiesis and is produced by the kidney and the liver in an oxygen-dependent manner. We and others have recently...

Digicaylioglu M, Bichet S, Marti H, Wenger R, Rivas L, Bauer C, et al.
Proc Natl Acad Sci U S A . 1995 Apr; 92(9):3717-20. PMID: 7731971
The main physiological regulator of erythropoiesis is the hematopoietic growth factor erythropoietin (EPO), which is induced in response to hypoxia. Binding of EPO to the EPO receptor (EPO-R), a member...

Rivas L, Pont Lezica R
Eur J Biochem . 1987 Feb; 163(1):135-40. PMID: 3816793
When Prototheca zopfii cells were pulse-labeled with 14C-containing amino acids and homogenized, 14C-labeled membranes were obtained. In vitro incubations with the previously labeled membranes and UDP-[3H]Glc produced a trichloroacetic-acid-insoluble fraction...

Rivas L, Pont Lezica R
Eur J Biochem . 1987 Feb; 163(1):129-34. PMID: 3816792
Membrane preparations from the non-photosynthetic alga Prototheca zopfii incorporate glucose from UDP-[3H]glucose into the trichloroacetic-acid-insoluble fraction and the polysaccharides insoluble in hot alkali. Time course and pulse-chase experiments indicate that...
