Trypanosoma cruzi: Variability of stocks from Colombia determined by molecular karyotype and minicircle Southern blot analysis
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2006-05)
Nineteen Trypanosoma cruzi. stocks, most of them of wild origin, and four Trypanosoma rangeli stocks from Colombia were analysed by molecular karyotype analysis with cloned DNA cruzipain as the probe. Another 27 cloned ...
Adaptive response of the archaeon Sulfolobus acidocaldarius BC65 to phosphate starvation
(Microbiology Society, 1996)
The adaptive response of the archaeon Sulhlobus acidocaldarius BC65 to
phosphate starvation was studied. When cells were subjected to phosphate
limitation, their growth was affected. In addition, the levels of synthesis
andlor ...
Melatonin prevents damage elicited by the organophosphorous pesticide diazinon on mouse sperm DNA
(2009)
Toxic effects of pesticides are commonly associated with DNA damage. To evaluate the effect of the organophosphate diazinon on sperm DNA and to test whether melatonin could prevent this damage, male mice were intraperitoneally ...
Molecular cloning, sequencing, and expression of a chemoreceptor gene from Leptospirillum ferrooxidans
(1998)
We have cloned and sequenced a 2,262-bp chromosomal DNA fragment from the chemolithoautotrophic acidophilic bacterium Leptospirillum ferrooxidans. This DNA contained an open reading frame for a 577oaminoacid protein showing ...
Effects of A and B ultraviolet irradiation on human lymphocytes Efectos de la radiación ultravioleta A y B sobre linfocitos humanos.
(1994)
Over the last decade, a greater decrease in the ozone level has occurred in the Southern Hemisphere. For each 1% decrease in this level, a 2% increase in biologically effective radiation occurs. Aiming to evaluate the ...
Androgen receptor gene CAG and GGN repeat polymorphisms in Chilean men with primary severe spermatogenic failure
(2010)
There is ample documentation supporting the fact that androgens are required for normal spermatogenesis. A minority of infertile men have abnormal testosterone blood levels or mild androgen receptor mutations. We investigated ...
Characterization of the acetohydroxyacid synthase multigene family in the tetraploide plant Chenopodium quinoa
(PUCV, 2015)
Background: Currently, the technology called Clearfield (R) is used in the development of crops resistant to herbicides that inhibit the enzyme acetohydroxy acid synthase (AHAS, EC 2.2.1.6). AHAS is the first enzyme of the ...
The G2 checkpoint activated by DNA damage does not prevent genome instability in plant cells
(2006)
Root growth, G2 length, and the frequency of aberrant mitoses and apoptotic nuclei were recorded after a
single X-ray irradiation, ranging from 2.5 to 40 Gy, in Allium cepa L. root meristematic cells. After 72 h of
recovery, ...
Complete genome sequence of Piscirickettsia salmonis LF-89 (ATCC VR-1361) a major pathogen of farmed salmonid fish
(Elsevier, 2015)
Piscirickettsia salmonis, the causative agent of salmonid rickettsial septicemia (SRS), is a significant threat
to the healthy and sustainable production of salmonid farming industry. This Gram-negative bacterium,
originally ...
Reduced Genetic Diversity and Increased Dispersal in Guigna (Leopardus guigna) in Chilean Fragmented Landscapes
(Oxford Univ Press, 2015)
Landscape fragmentation is often a major cause of species extinction as it can affect a wide variety of ecological processes. The impact of fragmentation varies among species depending on many factors, including their ...
