Physical review. E

Metselaar L, Dozov I, Antonova K, Belamie E, Davidson P, Yeomans JM, Doostmohammadi A.
PMID: 28950460
Phys Rev E. 2017 Aug;96(2):022706. doi: 10.1103/PhysRevE.96.022706. Epub 2017 Aug 09.

The occurrence of new textures of liquid crystals is an important factor in tuning their optical and photonics properties. Here, we show, both experimentally and by numerical computation, that under an electric field chitin tactoids (i.e., nematic droplets) can...

PMID: 16661507
Plant Physiol. 1980 Oct;66(4):710-4. doi: 10.1104/pp.66.4.710.

Whole shoots of Phaseolus vulgaris L. and other species were exposed to a range of partial pressures of gaseous ammonia in air and the resulting fluxes were measured. Net uptake is linear with partial pressure in the range 5...

Chemphyschem. 2007 Aug 24;8(12):1850-6. doi: 10.1002/cphc.200700251.

The structure of the active complex in the Ni-catalyzed polymerization of isocyanides to give polyisocyanides is investigated. It is shown by X-ray absorption spectroscopy (XAS), including EXAFS (extended X-ray absorption fine structure) and XANES (X-ray absorption near edge structure),...

Topological states in chiral active matter: Dynamic blue phases and active half-skyrmions.

The Journal of chemical physics

Metselaar L, Doostmohammadi A, Yeomans JM.
PMID: 30769984
J Chem Phys. 2019 Feb 14;150(6):064909. doi: 10.1063/1.5085282.

We numerically study the dynamics of two-dimensional blue phases in active chiral liquid crystals. We show that introducing contractile activity results in stabilised blue phases, while small extensile activity generates ordered but dynamic blue phases characterised by coherently moving...

Development and characterization of liposomal formulation of bortezomib.

International journal of pharmaceutics: X

Bortezomib is a proteasome inhibitor used for the treatment of multiple myeloma. The poor pharmacokinetic profile and off-target adverse effects provide a strong incentive to develop drug delivery systems for bortezomib. In the past, liposomal encapsulation has been proven...

A pilot study on the use of prednisolone-encapsulated liposomes for the treatment of moderate-to-severe Graves' orbitopathy with reduced systemic steroid exposure.

PURPOSE: To demonstrate that long-circulating PEGylated liposomal prednisolone is a safe and effective therapy in patients with active moderate-to-severe Graves' orbitopathy.METHODS: Open-label, proof-of-concept, multicentre pilot study. Ten patients with moderate-to-severe Graves's orbitopathy, who were euthyroid for at least three...

Glucocorticoids (GCs) are potent anti-inflammatory drugs but their use is limited by systemic exposure leading to toxicity. Targeted GC delivery to sites of inflammation via encapsulation in long-circulating liposomes may improve the therapeutic index. We performed a randomized, double-blind,...

An exploratory first-in-man study to investigate the pharmacokinetics and safety of liposomal dexamethasone at a 2- and 1-week interval in patients with metastatic castration resistant prostate cancer.

Dexamethasone has antitumor activity in metastatic castration resistant prostate cancer (mCRPC). We aimed to investigate intravenous liposome-encapsulated dexamethasone disodium phosphate (liposomal dexamethasone) administration in mCRPC patients. In this exploratory first-in-man study, patients in part A received a starting dose...

Topology and Morphology of Self-Deforming Active Shells.

Phys Rev Lett. 2019 Nov 15;123(20):208001. doi: 10.1103/PhysRevLett.123.208001.

We present a generic framework for modeling three-dimensional deformable shells of active matter that captures the orientational dynamics of the active particles and hydrodynamic interactions on the shell and with the surrounding environment. We find that the cross talk...

A general nomenclature applicable to the phases that form in any sequence of transitions in the solid state has been recommended by an IUCr Working Group [Acta Cryst. (1998). A54, 1028-1033]. The six-field notation of the first Report, hereafter...
