Suprasellar and third ventricular cavernous malformation: Lessons learned in differential diagnosis and surgical planning.

Surgical neurology international

Kulason KO, Schneider JR, Rahme R, Ratzon F, Anderson TA, Shatzkes DR, Filippi CG, Costantino PD, Langer DJ, Boockvar JA.

BACKGROUND: While craniopharyngiomas (CPs) are the most common cystic suprasellar lesions in adults, cavernous malformations (CMs) only exceptionally occur in this location and are seldom considered in the differential diagnosis of such lesions. However, unlike CPs, suprasellar CMs are...

Human Y-chromosome SNP characterization by multiplex amplified product-length polymorphism analysis.

Electrophoresis

Medina LS, Muzzio M, Schwab M, Costantino ML, Barreto G, Bailliet G.
PMID: 24846779
Electrophoresis. 2014 Sep;35(17):2524-7. doi: 10.1002/elps.201400020. Epub 2014 Jul 14.

We designed an allele-specific amplification protocol to optimize Y-chromosome SNP typing, which is an unavoidable step for defining the phylogenetic status of paternal lineages. It allows the simultaneous highly specific definition of up to six mutations in a single...

Co-Deposition of Gold Nanoparticles and Metalloporphyrin Using the Langmuir-Blodgett (LB) Technique for Surface-Enhanced Raman Scattering (SERS).

The synergistic effect produced by metallic nanoparticles when incorporated into different systems empowers a research field that is growing rapidly. In addition, organometallic materials are at the center of intensive research with diverse applications such as light-emitting devices, transistors,...

Hydroxyapatite cement, a smart biomaterial for craniofacial skeletal tissue engineering.

Surgical technology international

Friedman CD, Costantino PD.
PMID: 12722010
Surg Technol Int. 1998;7:421-3.

Craniofacial skeletal surgery continues to command special interest from patients and clinicians dealing with skeletal defects. Autologous bone grafts remain the standard treatment by which bone substitutes are compared. A continued interest in avoiding donor sites and realizing "off...

Fabrication of high-mechanical-resistance Bragg gratings in single-mode optical fibers with continuous-wave ultraviolet laser side exposure.

Optics letters

Varelas D, Costantini DM, Limberger HG, Salathé RP.
PMID: 18084524
Opt Lett. 1998 Mar 01;23(5):397-9. doi: 10.1364/ol.23.000397.

The mechanical resistance of single-mode fibers containing fiber Bragg gratings inscribed with cw UV laser irradiation is almost identical to that of pristine fiber. The median breaking strength of the gratings' Weibull distribution is more than 5 GPa, and...

Molecular and morphological characterization of bis benzimidazo perylene films and surface-enhanced phenomena.

The journal of physical chemistry. B

Volpati D, Job AE, Aroca RF, Constantino CJ.
PMID: 18335918
J Phys Chem B. 2008 Apr 03;112(13):3894-902. doi: 10.1021/jp077588h. Epub 2008 Mar 12.

Thin solid films of bis benzimidazo perylene (AzoPTCD) were fabricated using physical vapor deposition (PVD) technique. Thermal stability and integrity of the AzoPTCD PVD films during the fabrication ( approximately 400 degrees C at 10(-6) Torr) were monitored by...

Starting to move through a granular medium.

Physical review letters

Costantino DJ, Scheidemantel TJ, Stone MB, Conger C, Klein K, Lohr M, Modig Z, Schiffer P.
PMID: 18851259
Phys Rev Lett. 2008 Sep 05;101(10):108001. doi: 10.1103/PhysRevLett.101.108001. Epub 2008 Sep 03.

We explore the process of initiating motion through a granular medium by measuring the force required to push a flat circular plate upward from underneath the medium. In contrast with previous measurements of the drag and penetration forces, which...

[Sexual rehabilitation with intracavernous PGE1 injections and oral drug administration in diabetic patients non-responder to oral therapy alone].

Urologia

Passavanti G, Vizzuti V, Pizzuti V, Carlucci M, Aloisi AM, Costantini FM, Bragaglia A, Paolini R.
PMID: 21086406
Urologia. 2007 Apr-Jun;74(2):95-8. doi: 10.5301/ru.2010.5868.

Diabetes is an important risk factor in erectile dysfunction (ED), acting via several mechanisms. We assessed the efficacy of intracavernous injections (ICI) rehabilitation and oral systematic therapy in diabetic patients, as well as the response of controls to oral...

Fast dynamics in the optical storage with Langmuir-Blodgett films of a diazocrown ether molecule.

Journal of nanoscience and nanotechnology

Shimizu FM, Ferreira M, Constantino CJ, Skwierawska AS, Biernat JF, Giacometti JA.
PMID: 19205208
J Nanosci Nanotechnol. 2008 Dec;8(12):6367-75. doi: 10.1166/jnn.2008.447.

Azobenzene-containing molecules have been studied for a number of applications exploiting the efficient trans-cis-trans photoisomerization cycles, which lead to molecular alignment and even micrometer-scale mass transport. One of the limitations of these materials, though, is the slow dynamics of...
