Morphology transformation between nanofibres and vesicles controlled by ultrasound and heat in tryptamine-based assembly

<p>A novel low-molecular-mass organic gelator <b>T1</b> containing tryptamine and sugar segments was designed and synthesised which can gelate alcohols accelerated by heat and sonication. Interestingly, morphology exchange between vesicles as precipitate and a three-dimensional gel network tuned by heating and ultrasound was observed. The mechanism was studied by IR, FL, X-ray diffraction. It was presented that the effect of ultrasound was to disturb the spontaneous self-assembly of <b>T1</b> molecule, and promote the long arrangement and disordered assembly of <b>T1</b> molecules into fibrous networks, thus resulting in the gelation in methanol.</p

Alignment of EGF-like repeat domain of NOTCH3.

<p>Alignment of C4–C6 in EGF-like domains of NOTCH3 was shown in the upper panel (A). Conserved G36 in human EGF is shown in the most EGF-like domains of NOTCH3. Alignment of C4–C6 in EGF-like repeat domain 3 homolog from different species was shown in the middle panel of the figure (B). Amino acid sequence alignment from various species showed the conservation of this glycine residue. The reported CADASIL mutations within this EGF-like repeat domain were indicated in the lower panel (C).</p

Brain MRI images of the proband showing characteristic diffuse leukoencephalopathy.

<p>T2-weighted MRI images (A–C) showed diffuse hyperintensities in the periventricular white matter with a symmetrical distribution, the centrum semiovale, and the basal ganglia. Fluid-attenuated inversion recovery (FLAIR) T2 sequences (D–F) revealed confluent white-matter lesions in multiple brain regions. Diffusion-weighted imaging (DWI) sequence (G) demonstrated acute ischemic stroke in the centrum semiovale. MR angiography (H) revealed no intracranial arterial stenosis or occlusion.</p
