Only borderline correlations were obtained for achieved refractive correction with ultrasound and OCR [J Refract Surg. 2009;25:699-708.] doi:10.3928/1081597X-20090707-04″
“Purpose: Concerns about the safety of formocresol (FC) as a pulpotomy agent

in Pediatric Dentistry have lead to the search of LY294002 clinical trial new capping medicaments. Indigenous plant medicines such as Nigella Sativa (NS) have been the focus of many researches. Therefore the purpose of this study was to investigate histo-pathologically the pulp response to NS oil and FC in dogs. Method: Forty teeth in 4 male dogs of undefined breed aging 12-14 months were used in this. study. Coronal access cavities were performed on the upper and lower premolars so that both medicaments were tested in the same animal in alternate sides of the mouth. Four weeks after treatment the animals were sacrificed, paraffin sections were prepared for histological,

histochemical and immuno-histochemical staining. Results: specimens in the NS group showed mild to moderate Nepicastat concentration vasodilatation. Few specimens showed scattered inflammatory cell infiltration and the odontoblastic layer was continuous. While the FC group showed moderate to severe vasodilatation with high inflammatory cell infiltrate and degenerative changes. Conclusions: NS possesses an anti-inflammatory effect and the pulp maintains its vitality after its application, which could qualify its use as a pulp medicament for pulpotomized teeth in clinical practice.”
“Generation of induced pluripotent stem cells (iPSCs) by defined factors is an extremely inefficient process, because there is a strong epigenetic block preventing cells from achieving

pluripotency. Here we report that virally expressed factors bound to the promoters of their target genes to the same extent in both iPSCs and unreprogrammed cells (URCs). However, expression of endogenous pluripotentcy genes was observed only in iPSCs. Comparison of local chromatin structure of the OCT4 locus revealed RG7440 that there was a cohesin-complex-mediated intrachromosomal loop that juxtaposes a downstream enhancer to the gene’s promoter, enabling activation of endogenous stemness genes. None of these long-range interactions were observed in URCs. Knockdown of the cohesin-complex gene SMC1 by RNAi abolished the intrachromosomal interaction and affected pluripotency. These findings highlight the importance of the SMC1-orchestrated intrachromosomal loop as a critical epigenetic barrier to the induction of pluripotency.”
