Canine distemper virus infection in a lesser grison (Galictis cuja): first report and virus phylogeny Infecção pelo vírus da cinomose canina em um furão (Galictis cuja): primeiro relato e filogenia viral

Pesquisa Veterinária Brasileira, 2013
Infectious diseases in wild animals have been increasing as a result of their habitat alterations and closer contact with domestic animals. Canine distemper virus (CDV) has been reported in several species of wild carnivores, presenting a threat to ...

Nonlinearities and Switch‐Like Behavior in Gene Expression: From Genetics to Biochemistry and Back

The FASEB Journal, Volume 40, Issue 16, 31 August 2026.
Modest changes in transcription‐factor or chromatin‐regulator dosage can have disproportionate effects when gene‐regulatory systems operate near nonlinear thresholds. Sigmoidal input–output relationships, chromatin and cofactor recruitment, and changes in threshold position or response steepness provide molecular routes by which quantitative dosage ...

Targeting Human Immunodeficiency Virus Integrase Beyond the Active Site: The Discovery and Development of Allosteric Integrase Inhibitors

ChemMedChem, Volume 21, Issue 16, 27 August 2026.
Human immunodeficiency virus (HIV) allosteric integrase inhibitors (ALLINIs) offer a vital alternative to standard therapies by targeting noncatalytic sites. By inducing aberrant integrase multimerization, they disrupt viral maturation. This review explores their medicinal chemistry evolution, detailing structural insights, structure–activity ...

From Nucleobases to Bioactive NHC‐Based Gold and Silver Complexes With Anticancer and Antiviral Activity

ChemMedChem, Volume 21, Issue 16, 27 August 2026.
Herein, we reported the design and synthesis of a novel series of N‐heterocyclic carbene (NHC) complexes originated from the imidazole ring of guanine and guanosine and with different counterions (iodide, acetate, and aminoacidate). The evaluation of the biological activities, that is anticancer and antiviral, indicated L2AuOAc as the best complex ...

Studies of the formation and transcription of class II promoter-containing ordered nucleoprotein complexes in vitro

, 1984
Incubation of supercoiled SV40 DNA with three different HeLa cell free transcription extracts caused the DNA to be converted into ordered nucleoprotein complexes whose physical structure resembled the beads-on-a-string morphology of SV40 ...
