Sci-Fri AM: Imaging - 06: The role of body mass and gender in atlas construction for attenuation correction in PET/MRI.

Medical physics

Patrick J, Marshall H, Sabondjian E, Butler J, Rachinsky I, Thompson T, Théberge J, Prato F, Stodilka R.
PMID: 28516638
Med Phys. 2012 Jul;39(7):4641. doi: 10.1118/1.4740192.

Attenuation correction (AC) in PET/MRI is difficult as there is no clear relationship between MR signal and 511 keV attenuation coefficients (μ) as there is with CT. One approach is to register a pre-defined atlas of μ to the...

Bistable regimes in an optically injected mode-locked laser.

Optics express

Habruseva T, Hegarty SP, Vladimirov AG, Pimenov A, Rachinskii D, Rebrova N, Viktorov EA, Huyet G.
PMID: 23187375
Opt Express. 2012 Nov 05;20(23):25572-83. doi: 10.1364/OE.20.025572.

We study experimentally the dynamics of quantum-dot (QD) passively mode-locked semiconductor lasers under external optical injection. The lasers demonstrated multiple dynamical states, with bifurcation boundaries that depended upon the sign of detuning variation. The area of the hysteresis loops...

Lack of an Effect of Supratherapeutic Dose of Venlafaxine on Cardiac Repolarization in Healthy Subjects.

Clinical pharmacology in drug development

Abbas R, Riley S, Nepal S, Bachinsky M, Lee KC, Chappell PB, Damle B.
PMID: 34242472
Clin Pharmacol Drug Dev. 2022 Jan;11(1):100-111. doi: 10.1002/cpdd.989. Epub 2021 Jul 09.

This single-center, randomized, 3-way crossover thorough QT study evaluated the effect of steady-state supratherapeutic venlafaxine (Effexor) on cardiac repolarization. Fifty-four healthy adults received double-blinded extended-release venlafaxine 450 mg/d and placebo and open-label positive-control moxifloxacin 400 mg. The postdose QT...

A deterministic model for non-monotone relationship between translation of upstream and downstream open reading frames.

Mathematical medicine and biology : a journal of the IMA

Andreev DE, Baranov PV, Milogorodskii A, Rachinskii D.
PMID: 34718568
Math Med Biol. 2021 Dec 15;38(4):490-515. doi: 10.1093/imammb/dqab015.

Totally asymmetric simple exclusion process (TASEP) modelling was shown to offer a parsimonious explanation for the experimentally confirmed ability of a single upstream open reading frames (uORFs) to upregulate downstream translation during the integrated stress response. As revealed by...

Optically injected mode-locked laser.

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

Rebrova N, Huyet G, Rachinskii D, Vladimirov AG.

Phys Rev E Stat Nonlin Soft Matter Phys. 2011 Jun;83(6):066202. doi: 10.1103/PhysRevE.83.066202. Epub 2011 Jun 07.

We study analytically and numerically a delay differential model of a passively mode-locked semiconductor laser subjected to a single-frequency coherent injection. The width of the locking cone is calculated asymptotically in the limit of small injection and zero line-width...

Familial papillary thyroid carcinoma: a retrospective analysis.

J Oncol. 2011;2011:948786. doi: 10.1155/2011/948786. Epub 2011 Oct 25.

Background. Whether or not the familial form of papillary thyroid carcinoma is more aggressive than the sporadic form of the disease remains controversial. Methods. To explore this question and whether or not increased aggressiveness is more apparent in families...

Sex-specific developmental profiles of juvenile hormone synthesis in honey bee larvae.

Roux's archives of developmental biology : the official organ of the EDBO

PMID: 28305995
Rouxs Arch Dev Biol. 1993 Feb;202(3):176-180. doi: 10.1007/BF00365308.

Juvenile hormone synthesis in drone larvae of the honey bee was measured by an in vitro radiochemical assay. The developmental profile of corpora allata activity in male larvae showed considerable differences from queen larvae, the presumptive reproductive females, and...
