SC-44368 (5-[6-(1-cyclohexyl-1H-tetrazol-5-y)hexyl]-1,8-naphthyridin-2(1H)-one) is a potent and selective competitive inhibitor of platelet cyclic AMP-dependent phosphodiesterase (cAMP-PDE) (Ki: 1.65 μM). For the phosphodiesterase isoenzyms from human platelets SC-44368 shows a 26-fold selectivity (IC50 ratio) for the inhibition of the cAMP-PDE over...

Measurement of Forces between Supported Cationic Bilayers by Colloid Probe Atomic Force Microscopy: Electrolyte Concentration and Composition.

Langmuir : the ACS journal of surfaces and colloids

Leivers M, Seddon JM, Declercq M, Robles E, Luckham P.
PMID: 30562468
Langmuir. 2019 Jan 22;35(3):729-738. doi: 10.1021/acs.langmuir.8b03555. Epub 2019 Jan 09.

The interactions between supported cationic surfactant bilayers were measured by colloidal probe atomic force spectroscopy, and the effect of different halide salts was investigated. Di(alkylisopropylester)dimethylammonium methylsulfate (DIPEDMAMS) bilayers were fabricated by the vesicle fusion technique on muscovite mica. The...

Gender-affirming care, mental health, and economic stability in the time of COVID-19: a global cross-sectional study of transgender and non-binary people.

medRxiv : the preprint server for health sciences

Jarrett BA, Peitzmeier SM, Restar A, Adamson T, Howell S, Baral S, Beckham SW.
PMID: 33173876
medRxiv. 2020 Nov 04; doi: 10.1101/2020.11.02.20224709.

BACKGROUND: Transgender and non-binary people are disproportionately burdened by barriers to quality healthcare, mental health challenges, and economic hardship. This study examined the impact of the novel coronavirus disease (COVID-19) pandemic and subsequent control measures on gender-affirming care, mental...

Opt Express. 2005 Jul 11;13(14):5338-46. doi: 10.1364/opex.13.005338.

We propose a criterion to predict the relative value of the stimulated Brillouin scattering (SBS) threshold in single-mode optical fibers with different refractive index profiles. We confirm our results by several representative measurements. We show that with the proper...
