Identification of two novel cytolysins from the hydrozoan Olindias sambaquiensis (Cnidaria)
(Biomed Central Ltd., 2014-03-25)
Background: Although the hydrozoan Olindias sambaquiensis is the most common jellyfish associated with human envenomation in southeastern and southern Brazil, information about the composition of its venom is rare. Thus, ...
A Long-Term Conserved Satellite DNA That Remains Unexpanded in Several Genomes of Characiformes Fish Is Actively Transcribed
(2021-02-03)
Eukaryotic genomes contain large amounts of repetitive DNA sequences, such as tandemly repeated satellite DNAs (satDNAs). These sequences are highly dynamic and tend to be genus- or species-specific due to their particular ...
Community transmission of multidrug-resistant tuberculosis is associated with activity space overlap in Lima, Peru
(BioMed Central, 2021)
BACKGROUND: Transmission of multidrug-resistant tuberculosis (MDRTB) requires spatial proximity between infectious cases and susceptible persons. We assess activity space overlap among MDRTB cases and community controls ...
Investigation of Thrombin Activity with PAR 1-based Fluorogenic Peptides
(Bentham Science Publ Ltd, 2013-10-01)
Thrombin, a highly specific protease of blood coagulation, has two exosites that modulate its specificity. We designed two sets of synthetic substrate FRET peptides with 25- or 11-amino acids (aa) each, based on the PAR 1 ...
Base-metal deposits of the Cordillera Negra, departamento de Ancash, Peru
(United States Government Printing OfficeUS, 1957)
The Cordillera Negra, the westernmost range in the Departamento de Ancash, is just north of the central mineral province of Peru. Within several kilometers of its crest and along a length of 140 kllometers are more than ...
A DNA segment encoding the anticodon stem/loop of tRNA determines the specific recombination of integrative-conjugative elements in Acidithiobacillus species
(2018)
Horizontal gene transfer is crucial for the adaptation of microorganisms to environmental cues. The acidophilic, bioleaching bacterium Acidithiobacillus ferrooxidans encodes an integrative-conjugative genetic element ...
