Placental hydroxymethylation vs methylation at the imprinting control region 2 on chromosome 11p15.5.

Brazilian journal of medical and biological research = Revista brasileira de pesquisas medicas e biologicas

Magalhães HR, Leite SB, Paz CC, Duarte G, Ramos ES.
PMID: 24270911
Braz J Med Biol Res. 2013 Nov;46(11):916-919. doi: 10.1590/1414-431X20133035. Epub 2013 Oct 22.

In addition to methylated cytosines (5-mCs), hydroxymethylcytosines (5-hmCs) are present in CpG dinucleotide-enriched regions and some transcription regulator binding sites. Unlike methylation, hydroxymethylation does not result in silencing of gene expression, and the most commonly used methods to study...

Exploring Dangerous Connections between Klebsiella pneumoniae Biofilms and Healthcare-Associated Infections.

Pathogens (Basel, Switzerland)

Bandeira M, Carvalho PA, Duarte A, Jordao L.
PMID: 25438020
Pathogens. 2014 Aug 19;3(3):720-31. doi: 10.3390/pathogens3030720.

Healthcare-associated infections (HAI) are a huge public health concern, particularly when the etiological agents are multidrug resistant. The ability of bacteria to develop biofilm is a helpful skill, both to persist within hospital units and to increase antibiotic resistance....

The Schiff base N,N'-ethylenebis(pyridoxylideneiminato) (H(2)pyr(2)en, 1) was synthesized by reaction of pyridoxal with ethylenediamine; reduction of H(2)pyr(2)en with NaBH(4) yielded the reduced Schiff base N,N'-ethylenebis(pyridoxylaminato) (H(2)Rpyr(2)en, 2); their crystal structures were determined by X-ray diffraction. The totally protonated forms...
