Rehabilitation with cochlear implant in patient with harboyan syndrome.

International archives of otorhinolaryngology

Paniagua LM, Dorfman ME, Lavinsky L, Sleifer P.
PMID: 25992045
Int Arch Otorhinolaryngol. 2013 Oct;17(4):403-6. doi: 10.1055/s-0033-1351669.

Background Harboyan syndrome, defined as congenital corneal dystrophy associated with progressive sensorineural hearing loss, was first described by Harboyan in 1971. It is a hereditary disease manifested by eye lesions consistent with corneal endothelial dystrophy and progressive sensorineural hearing...

Prevention of protein adsorption by flexible and rigid chain molecules.

Colloids and surfaces. B, Biointerfaces

Carignano MA, Szleifer I.
PMID: 10915942
Colloids Surf B Biointerfaces. 2000 Oct 01;18(3):169-182. doi: 10.1016/s0927-7765(99)00146-0.

The ability of tethered polymer layers to reduce the non-specific adsorption of proteins is studied using a molecular theory. The protein adsorption isotherms are calculated for flexible and rigid molecules as well as for mixtures. It is found, in...

Statistical thermodynamics of amphiphile chains in micelles.

Proceedings of the National Academy of Sciences of the United States of America

Ben-Shaul A, Szleifer I, Gelbart WM.
PMID: 16593492
Proc Natl Acad Sci U S A. 1984 Jul;81(14):4601-5. doi: 10.1073/pnas.81.14.4601.

The probability distribution of amphiphile chain conformations in micelles of different geometries is derived through maximization of their packing entropy. A lattice model, first suggested by Dill and Flory, is used to represent the possible chain conformations in the...

Analytic density-functional self-consistent-field theory of diblock copolymers near patterned surfaces.

The Journal of chemical physics

Seok C, Freed KF, Szleifer I.
PMID: 15267625
J Chem Phys. 2004 Apr 15;120(15):7174-82. doi: 10.1063/1.1669372.

Analytical solutions are derived for the density profiles and the free energies of compressible diblock copolymer melts (or incompressible copolymer solutions) near patterned surfaces. The density-functional self-consistent-field theory is employed along with a Gaussian chain model for bonding constraints...

Chiral separation: mechanism modeling in two-dimensional systems.

Journal of the American Chemical Society

Paci I, Szleifer I, Ratner MA.
PMID: 17338520
J Am Chem Soc. 2007 Mar 28;129(12):3545-55. doi: 10.1021/ja066422b. Epub 2007 Mar 06.

Fluid phase separations of racemates are difficult because the subtle, short-ranged differences in intermolecular interactions of like and unlike pairs of chiral molecules are typically smaller than the thermal energy. A surface restricts the configurational space available to the...

Transport rectification in nanopores with outer membranes modified with surface charges and polyelectrolytes.

ACS nano

Tagliazucchi M, Rabin Y, Szleifer I.
PMID: 24047263
ACS Nano. 2013 Oct 22;7(10):9085-97. doi: 10.1021/nn403686s. Epub 2013 Sep 27.

This work reports a comprehensive theoretical study of the transport-rectification properties of cylindrical nanopores with neutral inner walls and chemically modified outer membrane. The chemical species on the two outer sides of the membrane have charges of opposite sign...

Equilibrium adsorption of hexahistidine on pH-responsive hydrogel nanofilms.

Langmuir : the ACS journal of surfaces and colloids

Longo GS, de la Cruz MO, Szleifer I.
PMID: 25434993
Langmuir. 2014 Dec 23;30(50):15335-44. doi: 10.1021/la5040382. Epub 2014 Dec 12.

We present a molecular theory to study the adsorption of different species within pH-sensitive hydrogel nanofilms. The theoretical framework allows for a molecular-level description of all the components of the system, and it explicitly accounts for the acid-base equilibrium....

Automated coronary calcium scoring using deep learning with multicenter external validation.

NPJ digital medicine

Eng D, Chute C, Khandwala N, Rajpurkar P, Long J, Shleifer S, Khalaf MH, Sandhu AT, Rodriguez F, Maron DJ, Seyyedi S, Marin D, Golub I, Budoff M, Kitamura F, Takahashi MS, Filice RW, Shah R, Mongan J, Kallianos K, Langlotz CP, Lungren MP, Ng AY, Patel BN.

NPJ Digit Med. 2021 Jun 01;4(1):88. doi: 10.1038/s41746-021-00460-1.

Coronary artery disease (CAD), the most common manifestation of cardiovascular disease, remains the most common cause of mortality in the United States. Risk assessment is key for primary prevention of coronary events and coronary artery calcium (CAC) scoring using...

Theoretical Modeling of Chemical Equilibrium in Weak Polyelectrolyte Layers on Curved Nanosystems.

Polymers

Gonzalez Solveyra E, Nap RJ, Huang K, Szleifer I.
PMID: 33027995
Polymers (Basel). 2020 Oct 05;12(10). doi: 10.3390/polym12102282.

Surface functionalization with end-tethered weak polyelectrolytes (PE) is a versatile way to modify and control surface properties, given their ability to alter their degree of charge depending on external cues like pH and salt concentration. Weak PEs find usage...
