Optimizing the face Paradigm of BCI system by modified Mismatch Negative paradigm [PDF]

open access: yesFrontiers in Neuroscience, 2016
Many recent studies have focused on improving the performance of event-related potential (ERP) based brain computer interfaces (BCIs). The use of a face pattern has been shown to obtain high classification accuracies and information transfer rates (ITRs)

Refined HLA-DPB1 mismatch with molecular algorithms predicts outcomes in hematopoietic stem cell transplantation

open access: yesHaematologica, 2021
HLA-DPB1 mismatches between donor and recipient are commonly seen in allogeneic hematopoietic stem cell transplantation from an unrelated donor. HLA-DPB1 mismatch, conventionally determined by the similarity of the T-cell epitope (TCE), is associated ...

Mitral-aortic annular enlargement: modification of Manouguian's technique

open access: yesBrazilian Journal of Cardiovascular Surgery, 2002
We hereby present a technical modification for mitral-aortic annular enlargement. The mitral valve is replaced through the retro-septal approach, avoiding patches for left atrial roof closure.

A quantitative model predicts how m6A reshapes the kinetic landscape of nucleic acid hybridization and conformational transitions

open access: yesNature Communications, 2021
m6A RNA post-transcriptional modification changes RNA hybridization kinetics. Here the authors show that the methylamino group can adopt syn-conformation pairing with uridine with a mismatch-like conformation in RNA duplex.

Allele-Specific PCR for PIK3CA Mutation Detection Using Phosphoryl Guanidine Modified Primers

open access: yesDiagnostics, 2023
Phosphoryl guanidine (PG) is the novel uncharged modification of internucleotide phosphates of oligonucleotides. Incorporating PG modification into PCR primers leads to increased discrimination between wild-type and mutated DNA, providing extraordinary ...

Regulation of mismatch repair by histone code and posttranslational modifications in eukaryotic cells [PDF]

open access: yesDNA Repair, 2016
DNA mismatch repair (MMR) protects genome integrity by correcting DNA replication-associated mispairs, modulating DNA damage-induced cell cycle checkpoints and regulating homeologous recombination. Loss of MMR function leads to cancer development. This review describes progress in understanding how MMR is carried out in the context of chromatin and how
