Stability-Indicating HPLC Assay for Determination of Idebenone in Pharmaceutical Forms.

Journal of analytical methods in chemistry

Kombath S, Balde IB, Carret S, Kabiche S, Cisternino S, Fontan JE, Schlatter J.
PMID: 26605105
J Anal Methods Chem. 2015;2015:835986. doi: 10.1155/2015/835986. Epub 2015 Oct 29.

A stability-indicating method was validated for the determination in pharmaceutical forms of idebenone a coenzyme Q10-like compound. The assay was achieved by liquid chromatography analysis using a reversed-phase C18 column and a detector set at 480 nm. The optimized...

Toward high throughput optical metamaterial assemblies.

Applied optics

Fontana J, Ratna BR.
PMID: 26560623
Appl Opt. 2015 Nov 01;54(31):F61-9. doi: 10.1364/AO.54.000F61.

Optical metamaterials have unique engineered optical properties. These properties arise from the careful organization of plasmonic elements. Transitioning these properties from laboratory experiments to functional materials may lead to disruptive technologies for controlling light. A significant issue impeding the...

Diagnosis and management of supraglottitis (epiglottitis).

Current infectious disease reports

Glynn F, Fenton JE.
PMID: 18510881
Curr Infect Dis Rep. 2008 May;10(3):200-4. doi: 10.1007/s11908-008-0033-8.

Acute supraglottitis is a serious, potentially fatal infection in both adults and children. Haemophilus influenzae type b (Hib) is the most common cause in children, even in this era of the Hib vaccine. Most cases of acute supraglottitis in...

Novel cis-trans interactions are involved in post-transcriptional regulation of cyclin-dependent kinase inhibitor p21WAF1/CIP1 mRNA.

Journal of molecular signaling

Zhang L, Wali A, Fontana JA, Dawson MI, Rishi AK.
PMID: 20704727
J Mol Signal. 2010 Aug 12;5:12. doi: 10.1186/1750-2187-5-12.

BACKGROUND: A variety of pathways target CDKI p21WAF1/CIP1 expression at transcriptional, post-transcriptional as well as translational levels. We previously found that cell growth suppressing retinoid CD437 enhanced expression of p21WAF1/CIP1 and DNA damage inducible GADD45 proteins in part by...

Stabilization and reutilization of Bacillus megaterium glucose dehydrogenase by immobilization.

Applied biochemistry and biotechnology

Baron M, Fontana JD, Guimarães MF, Woodward J.
PMID: 18576086
Appl Biochem Biotechnol. 1997;63:257-68. doi: 10.1007/BF02920429.

Glucose dehydrogenase (GDH) from Bacillus megaterium was immobilized using aminopropyl controlled-pore silica (CPS, average pore sizes of 170 and 500 A) as a support and glutaraldehyde as a bifunctional crosslinking agent. The CPS-immobilized enzyme could be reused 12 times...

Stretch flow of confined non-Newtonian fluids: nonlinear fingering dynamics.

Physical review. E, Statistical, nonlinear, and soft matter physics

Brandão R, Fontana JV, Miranda JA.
PMID: 24483553
Phys Rev E Stat Nonlin Soft Matter Phys. 2013 Dec;88(6):063003. doi: 10.1103/PhysRevE.88.063003. Epub 2013 Dec 02.

We employ a weakly nonlinear perturbative scheme to investigate the stretch flow of a non-Newtonian fluid confined in Hele-Shaw cell for which the upper plate is lifted. A generalized Darcy's law is utilized to model interfacial fingering formation in...

A novel mechanism of cell growth regulation by Cell Cycle and Apoptosis Regulatory Protein (CARP)-1.

Journal of molecular signaling

Jiang Y, Puliyappadamba VT, Zhang L, Wu W, Wali A, Yaffe MB, Fontana JA, Rishi AK.
PMID: 20594350
J Mol Signal. 2010 Jul 01;5:7. doi: 10.1186/1750-2187-5-7.

BACKGROUND: CARP-1/CCAR1, a perinuclear phospho-protein, regulates signaling by adriamycin, steroids, or growth factors. However, intracellular events that regulate CARP-1-dependent cell growth are not fully understood.RESULTS: Here we investigated whether CARP-1 is involved in signaling induced by the protein kinase...
