Caging the uncageable: using metal complex release for photochemical control over irreversible inhibition.

Chemical communications (Cambridge, England)

Huisman M, White JK, Lewalski VG, Podgorski I, Turro C, Kodanko JJ.
PMID: 27711349
Chem Commun (Camb). 2016 Oct 18;52(85):12590-12593. doi: 10.1039/c6cc07083c.

Photochemical control over irreversible inhibition was shown using Ru(ii)-caged inhibitors of cathepsin L. Levels of control were dependent on where the Ru(ii) complex was attached to the organic inhibitor, reaching >10 : 1 with optimal placement. A new strategy...

Corners, cusps, and pearls in running drops.

Physical review letters

Podgorski T, Flesselles JM, Limat L.

Small drops sliding down a partially wetting substrate bifurcate between different shapes depending on their capillary number Ca. At low Ca, they are delimited by a rounded, smooth contact line. At intermediate values they develop a corner at the...

Fast measurements of concentration profiles inside deformable objects in microflows with reduced spatial coherence digital holography.

Applied optics

Minetti C, Callens N, Coupier G, Podgorski T, Dubois F.
PMID: 18846168
Appl Opt. 2008 Oct 10;47(29):5305-14. doi: 10.1364/ao.47.005305.

We investigate the use of a digital holographic microscope working with partially coherent spatial illumination to study concentration profiles inside confined deformable bodies flowing in microchannels. The studied phenomenon is rapidly changing in time and requires the recording of...

Photodarkening and photobleaching of an ytterbium-doped silica double-clad LMA fiber.

Optics express

Manek-Hönninger I, Boullet J, Cardinal T, Guillen F, Ermeneux S, Podgorski M, Bello Doua R, Salin F.
PMID: 19532394
Opt Express. 2007 Feb 19;15(4):1606-11. doi: 10.1364/oe.15.001606.

We studied the temporal evolution of the photodarkening effect in an Yb-doped silica LMA fiber. The absorption spectra exhibit an increase in absorption in the visible and in the near infrared spectral range when the fiber is exposed to...

Standard B presentation vs. contrast-enhanced ultrasound (US-CE). A comparison of usefulness of different ultrasonographic techniques in the evaluation of the echo structure and size of haematomas inpost-renal transplant patients: A preliminary report.

Polish journal of radiology

Grzelak P, Kurnatowska I, Nowicki M, Strzelczyk J, Sapieha M, Podgórski M, Marchwicka-Wasiak M, Stefańczyk L.
PMID: 23049576
Pol J Radiol. 2012 Jul;77(3):14-8. doi: 10.12659/pjr.883369.

BACKGROUND: During routine ultrasonographic examination in B presentation, performed as a standard diagnostic procedure during the early post-operative period, the most important problem with the interpretation of the images of perirenal haematoma is their ability to change in time....

PURPOSE: The aim of this volumetric study was to evaluate the relationship between brain atrophy quantification in multiple sclerosis (MS) patients and the progression of disability measured by neurological standardised tests.MATERIAL AND METHODS: Seventeen patients (mean age 40.89 years)...

The extrema of circulating miR-17 are identified as biomarkers for aggressive prostate cancer.

American journal of cancer research

Dyson G, Farran B, Bolton S, Craig DB, Dombkowski A, Beebe-Dimmer JL, Powell IJ, Podgorski I, Heilbrun LK, Bock CH.
PMID: 30416858
Am J Cancer Res. 2018 Oct 01;8(10):2088-2095. eCollection 2018.

MicroRNAs (miRNAs) constitute short non-coding RNAs that can post-transcriptionally modulate the expression of many oncogenes and tumor suppressor genes engaged in key cellular processes. Deregulated serum miRNA signatures have been detected in various solid cancers including prostate cancer, suggesting...

The aim of the study was to evaluate the impact of the competitive phase on physiological and metabolic indices and selected markers of skeletal muscle damage in male volleyball players. The study group consisted of 24 young male volleyball...

Nanoscale Ion Emitters in Native Mass Spectrometry for Measuring Ligand-Protein Binding Affinities.

ACS central science

Nguyen GTH, Tran TN, Podgorski MN, Bell SG, Supuran CT, Donald WA.
PMID: 30834319
ACS Cent Sci. 2019 Feb 27;5(2):308-318. doi: 10.1021/acscentsci.8b00787. Epub 2019 Jan 14.

Electrospray ionization (ESI) mass spectrometry (MS) is a crucial method for rapidly determining the interactions between small molecules and proteins with ultrahigh sensitivity. However, nonvolatile molecules and salts that are often necessary to stabilize the native structures of protein-ligand...

Fluvial plain lake watersheds are usually highly urbanized and have high concentrations of chromophoric dissolved organic matter (CDOM). CDOM derived from the connecting urban channels usually share strong terrestrial and anthropogenic signals and net inflow runoff (Q

Magnetic resonance and computed tomography imaging fusion for live guidance of percutaneous pulmonary valve implantation.
