In this study, SRAP molecular maker approach was performed to investigate genetic diversity in the Salvia genus. A total of 205 DNA bands were produced from PCR amplification of 11 Salvia species and populations using 25 selective primer combinations, of which 204 polymorphic genetic loci accounted. The total number of amplified fragments ranged from 3 to 15. The genetic similarities of 11 coll...

background: since the introduction of the first radioimmunoassay, several improvements have been made in the design of immunoassays such as method of antibody production, labeling, automation and detection technology. we performed an analytical evaluation of the new electrochemiluminescent immunoassay (eclia) for serum tsh, ft4 and t3 in the elecsys 2010 immunoassay system and compared the resu...

Abstract Quantifying hair cortisol has become popular in wildlife ecology for its practical advantages evaluating stress. Before levels can be reliably interpreted, however, it is key to first understand the intrinsic factors explaining intra- and inter-specific variation. Bats are an ecologically diverse group of mammals that allow studying such Given many bat species threatened or have declin...

Variations in mitochondrial DNA characters were used to characterize two morphologically similar and sympatric species of Neotropical terrestrial rodents of the genus Proechimys (Mammalia: Echimyidae). We sequenced both cytochrome b (1140pb) and part of the control region (445pb) from four individuals of P. cuvieri and five of P. cayennensis from French Guiana, which allowed us to depict intra-...

SYNOPSIS. Intracranial stimulation was used as a reinforcer to condition fighting in paired rats. Stimulation for an implanted animal was made contingent upon responses which successively approximated those typical of attack. A stable pattern of aggression developed, the maintenance of which was possible on intermittent reinforcement schedules although at depressed frequencies. An implanted rat...

The ubiquitous Gram-negative bacterium Legionella pneumophila parasitizes environ mental amoebae and, upon inhalation, replicates in alveolar macrophages, thus causing a life-threatening pneumonia called "Legionnaires' disease." The opportunistic pathogen employs a bi-phasic life cycle, alternating between a replicative, non-virulent phase and a stationary, transmissive/virulent phase. L. pneum...
