Angiofibroma on cheek mucosa: a rare entity and its management with laser.

Journal of cutaneous and aesthetic surgery

Thakur RK, Madan E, Tomar A, Arora M.
PMID: 25722603
J Cutan Aesthet Surg. 2014 Oct-Dec;7(4):227-8. doi: 10.4103/0974-2077.150785.

A rare presentation of an angiofibroma in the oral cavity is reported, which was treated with a diode laser. The benefits of laser treatment include bloodless procedure with instant precise coagulation of vessels. Although rare and unusual, it is...

Turning T cells on: epigenetically enhanced expression of effector T-cell costimulatory molecules on irradiated human tumor cells.

Journal for immunotherapy of cancer

Kumari A, Cacan E, Greer SF, Garnett-Benson C.
PMID: 24829753
J Immunother Cancer. 2013 Sep 23;1:17. doi: 10.1186/2051-1426-1-17. eCollection 2013.

BACKGROUND: Sub-lethal doses of radiation can alter the phenotype of target tissue by modulating gene expression and making tumor cells more susceptible to T-cell-mediated immune attack. We have previously shown that sub-lethal tumor cell irradiation enhances killing of colorectal...

A survey of colonoscopic polypectomy practice amongst Israeli gastroenterologists.

Annals of gastroenterology

Carter D, Beer-Gabel M, Zbar A, Avidan B, Bardan E.
PMID: 24714780
Ann Gastroenterol. 2013;26(2):135-140.

BACKGROUND: Polypectomy techniques have been implicated as factors in the effectiveness of polyp resection. The range of polypectomy practices among gastroenterologists in Israel is unknown.METHODS: A structured survey was sent to all Israeli gastroenterology departments in all 15 major...

Separable measurement estimation of density matrices and its fidelity gap with collective protocols.

Physical review letters

Bagan E, Ballester MA, Gill RD, Muñoz-Tapia R, Romero-Isart O.
PMID: 17026016
Phys Rev Lett. 2006 Sep 29;97(13):130501. doi: 10.1103/PhysRevLett.97.130501. Epub 2006 Sep 25.

We show that there exists a gap between the performance of separable and collective measurements in the qubit mixed-state estimation that persists in the large sample limit. We characterize the gap with sharp asymptotic bounds on mean fidelity. We...

Multi-level diffractive optics for single laser exposure fabrication of telecom-band diamond-like 3-dimensional photonic crystals.

Optics express

Chanda D, Abolghasemi LE, Haque M, Ng ML, Herman PR.
PMID: 18825176
Opt Express. 2008 Sep 29;16(20):15402-14. doi: 10.1364/oe.16.015402.

We present a novel multi-level diffractive optical element for diffractive optic near-field lithography based fabrication of large-area diamond-like photonic crystal structure in a single laser exposure step. A multi-level single-surface phase element was laser fabricated on a thin polymer...

Discriminating States: the quantum Chernoff bound.

Physical review letters

Audenaert KM, Calsamiglia J, Muñoz-Tapia R, Bagan E, Masanes L, Acin A, Verstraete F.
PMID: 17501405
Phys Rev Lett. 2007 Apr 20;98(16):160501. doi: 10.1103/PhysRevLett.98.160501. Epub 2007 Apr 17.

We consider the problem of discriminating two different quantum states in the setting of asymptotically many copies, and determine the minimal probability of error. This leads to the identification of the quantum Chernoff bound, thereby solving a long-standing open...

Quantum yields for oxygenic and anoxygenic photosynthesis in the cyanobacterium Oscillatoria limnetica.

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

Oren A, Padan E, Avron M.
