Restriction endonuclease banding and digestion resistant heterochromatin in triatomines, genus Panstrongylus
(2000-07-01)
The present work realized a comparative study in meiosis of two triatomines, Panstrongylus herreri and P. megistus, by cytogenetic techniques involving the restriction endonucleases Hae III and Alu I and C-banding. The ...
PRP8 intein in Ajellomycetaceae family pathogens: Sequence analysis, splicing evaluation and homing endonuclease activity
(Academic Press Inc. Elsevier B.V., 2011-02-01)
Inteins are intervening sequences that are transcribed and translated with flanking host protein sequences and then self-excised by protein splicing. Bi-functional inteins also contain a homing endonuclease responsible for ...
Cytogenetic characterization of a supernumerary chromosome segment and of B-chromosomes in Astyanax scabripinnis (Teleostei, Characidae)
(Kluwer Academic Publ, 2000-01-01)
The chromosome complement of a local population of Astyanax scabripinnis in Brazil was investigated with emphasis on the study of the heterochromatin attached to the A-chromosomes and present in the macro B-chromosome. ...
Polymorphism of the ITS-2 region of the ribosomal DNA of the Triatominae Rhodnius domesticus, R-pictipes, R-prolixus and R-stali
(Blackwell Publishing, 2006-12-01)
The polymerase chain reaction-restriction fragment length polymorphism technique (PCR-RFLP) was used to compare Rhodnius domesticus (Neiva & Pinto), R. pictipes (Stal), R. prolixus (Stal) and R. stali (Lent; Jurberg & ...
Structural basis of nuclear import of flap endonuclease 1 (FEN1)
(Wiley-Blackwell, 2012-07-01)
Flap endonuclease 1 (FEN1) is a member of the nuclease family and is structurally conserved from bacteriophages to humans. This protein is involved in multiple DNA-processing pathways, including Okazaki fragment maturation, ...
R- and G-band patterns in Astyanax scabripinnis paranae (Pisces, Characiformes, Characidae)
(Sociedade Brasileira de Genética, 1999-06-01)
A ausência de bandas longitudinais em cromossomos de peixes tem sido associada a problemas técnicos nas preparações cromossômicas ou à ausência de uma compartimentalização estrutural no genoma dos peixes. No presente estudo, ...
PRP8 intein in cryptic species of Histoplasma capsulatum: Evolution and phylogeny
(2013-08-01)
The PRP8 intein is the most widespread intein among the Kingdom Fungi. This genetic element occurs within the prp8 gene, and is transcribed and translated simultaneously with the gene. After translation, the intein excises ...
The Vampirome: Transcriptome and proteome analysis of the principal and accessory submaxillary glands of the vampire bat Desmodus rotundus, a vector of human rabies
(2013-04-06)
Vampire bats are notorious for being the sole mammals that strictly feed on fresh blood for their survival. While their saliva has been historically associated with anticoagulants, only one antihemostatic (plasminogen ...
Ehrlichiosis in anemic, thrombocytopenic, or tick-infested dogs from a hospital population in South Brazil
(2003-11-28)
Ehrlichia canis has a worldwide distribution, but clinical manifestations may vary geographically. We selected 129 dogs to determine prevalence of ehrlichiosis in dogs with anemia, thrombocytopenia, or ticks presented to ...
