Molecular phylogenetic analysis sheds light on the diversity and evolutionary history of the Neotropical and African Triplophyllum (Tectariaceae)

Journal of Systematics and Evolution, EarlyView.
We used a molecular approach to resolve the evolutionary lineages of Neotropical Triplophyllum, uncovering that current species circumscriptions are hindered by high morphological homoplasy in indument characters. Our results support the recognition of three new species and provide a necessary neotypification for T.

Antifungal Susceptibility Profile and Biocide Tolerance in Clinically Relevant Yeasts: Implications for Therapy and Hospital Infection Control. [PDF]

Mycoses
ABSTRACT Background Opportunistic yeasts account for a substantial proportion of invasive fungal infections and are important agents of healthcare‐associated infections, especially in intensive care units (ICUs). Objectives To describe the clinical and epidemiological characteristics of hospitalized patients with positive cultures for medically ...

Regulation by the Transcriptional Regulator YdcI in E. coli and (p)ppGpp‐Dependent Activation of ydcI Expression

Molecular Microbiology, EarlyView.
YdcI, a LysR‐type transcription regulator in Escherichia coli, regulates loci like iraP and mqo. Its expression is induced by (p)ppGpp under stress conditions, and protein levels rise during mid‐exponential growth, connecting its role to stress response and metabolism control. ABSTRACT YdcI, a LysR‐type transcription regulator, has been associated with

The influence of flavin mononucleotide on interaction in ethidium bromide-DNA system

Біофізичний вісник, 2015
The study of intercalator ethidium bromide (EB) interaction with DNA in the presence of vitamin B2 analogue flavin mononucleotide (FMN) is carried out using the differential scanning calorimetry (DSC) and spectrophotometry (SF).

High prevalence of a host‐associated Anaplasma lineage in wild coatis (Nasua nasua) from the Brazilian Atlantic Forest

Medical and Veterinary Entomology, EarlyView.
Anaplasma sp. DNA was detected in 47.9% of free‐ranging coatis (Nasua nasua) sampled in Iguaçu National Park, southern Brazil. Molecular analyses revealed a genetically distinct Anaplasma lineage infecting coatis, differing from Anaplasma strains detected in associated tick populations.

Demyelination and remyelination after multiple intramedullary injections of ethidium bromide in Wistar rats

, 2015
The ethidium bromide model of demyelination has been employed to study the central nervous system response to several episodes of demyelination. Twenty-seven Wistar rats received 2 to 4 intraspinal injections of 1 mu l of either 0.1% ethidium bromide in ...
