29(6):817-821.
PMID: 32370623
Objective: The bell-bottom technique is a widely used technique to treat aortoiliac aneurysms with preservation of the hypogastric arteries. The published data are scarce with conflicting results regarding the evolution....

. 2019 Feb;
17(4):322-327.
PMID: 30787951
Complications such as pseudoaneurysms (PA) related to cervicothoracic venous access can be devastating. In this article, we present two similar cases in which technological advances impacted diagnosis, treatment, and results....

Velmurugu Y, Vivas P, Connolly M, Kuznetsov S, Rice P, Ansari A
Nucleic Acids Res
. 2017 Dec;
46(4):1741-1755.
PMID: 29267885
The dynamics and mechanism of how site-specific DNA-bending proteins initially interrogate potential binding sites prior to recognition have remained elusive for most systems. Here we present these dynamics for Integration...

Vivas P, Velmurugu Y, Kuznetsov S, Rice P, Ansari A
J Chem Phys
. 2013 Oct;
139(12):121927.
PMID: 24089739
Proteins that recognize and bind to specific sites on DNA often distort the DNA at these sites. The rates at which these DNA distortions occur are considered to be important...

Sen P, Vivas P, Dechassa M, Mooney A, Poirier M, Bartholomew B
Mol Cell Biol
. 2012 Nov;
33(2):360-70.
PMID: 23149935
The SWI/SNF chromatin remodeling complex changes the positions where nucleosomes are bound to DNA, exchanges out histone dimers, and disassembles nucleosomes. All of these activities depend on ATP hydrolysis by...

Vivas P, Velmurugu Y, Kuznetsov S, Rice P, Ansari A
J Mol Biol
. 2012 Feb;
418(5):300-15.
PMID: 22370561
How DNA-bending proteins recognize their specific sites on DNA remains elusive, particularly for proteins that use indirect readout, which relies on sequence-dependent variations in DNA flexibility/bendability. The question remains as...

Vivas P, Kuznetsov S, Ansari A
J Phys Chem B
. 2008 May;
112(19):5997-6007.
PMID: 18461910
To elucidate the nature of the transition-state ensemble along the reaction pathway from a nonspecific protein-DNA complex to the specific complex, we have carried out measurements of DNA bending/unbending dynamics...

Kuznetsov S, Sugimura S, Vivas P, Crothers D, Ansari A
Proc Natl Acad Sci U S A
. 2006 Nov;
103(49):18515-20.
PMID: 17124171
Regulation of gene expression involves formation of specific protein-DNA complexes in which the DNA is often bent or sharply kinked. Kinetics measurements of DNA bending when in complex with the...
