A Chemical and Enzymatic Approach to Study Site-Specific Sumoylation. [PDF]

open access: yes, 2015
A variety of cellular pathways are regulated by protein modifications with ubiquitin-family proteins. SUMO, the Small Ubiquitin-like MOdifier, is covalently attached to lysine on target proteins via a cascade reaction catalyzed by E1, E2, and E3 enzymes.

Printing and Rerouting of Elastic and Protease Responsive Shape Memory Hydrogel Filaments

open access: yesAdvanced Healthcare Materials, EarlyView.
A biofabrication strategy, Rerouting of Free‐Floating Suspended Hydrogel Filaments (REFRESH), is developed enabling the printing of highly elastic, reconfigurable protease‐responsive hydrogel filaments with shape memory properties. The filaments can be manually braided, knotted, and rerouted to create intricate cell‐laden 3D architectures, expanding ...

The Reaction of Azoxybenzene with Acetic Anhydride [PDF]

open access: yesBulletin of the Chemical Society of Japan, 1971
Abstract When azoxybenzene was allowed to react with equimolar amount of acetic anhydride, a mixture of azobenzene, acetanilide, and acetic acid was obtained along with such gaseous products as carbon dioxide, carbon monoxide and methane.

Processing for maximizing the level of crystallinity in linear aromatic polyimides [PDF]

open access: yes, 1991
The process of the present invention includes first treating a polyamide acid (such as LARC-TPI polyamide acid) in an amide-containing solvent (such as N-methyl pyrrolidone) with an aprotic organic base (such as triethylamine), followed by dehydrating ...

3D Bioprinted Renal Constructs Using Kidney‐Specific ECM Bioink System on Kidney Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
A kidney‐specific bioink derived from decellularized porcine kidney tissue supports the encapsulation, viability, and maturation of human primary kidney cells within 3D bioprinted constructs. In vivo, it also promotes the recruitment of host renal progenitor cells, collectively enhancing structural and functional regeneration of renal tissue.

Advancing from MOFs and COFs to Functional Macroscopic Porous Constructs

open access: yesAdvanced Materials, EarlyView.
This review study investigates the recent progress and methodologies for manufacturing metal–organic framework (MOF) or covalent–organic framework (COF)‐based 3D structured macroscopic porous constructs with high structural integrity, providing the possibility to control their porosity across dimensions.

Acetic anhydride–trifluoroacetic acid acetolysis for the estimation of glycerol in phosphatidyl choline by gas–liquid chromatography

open access: yesJournal of Lipid Research, 1965
Low glycerol recoveries are obtained when acetic anhydride–acetic acid acetolysis is used to dephosphorylate lecithin prior to glycerol (and fatty acid) analysis by saponification–acetylation and gas–liquid chromatography.Quantitative glycerol recoveries

Interactions with water of mixed acetic-fatty cellulose esters [PDF]

open access: yes, 2011
Cellulose powder was acylated with mixtures containing acetic, fatty and acetic-fatty anhydrides to form acetic-fatty cellulose esters. The total degree of substitution (DS) of the mixed cellulose esters (MCE) ranged from 2x10-2 to 2.92.

A Highly Adaptable Hydrogen Bond Re‐Orientation (HyBRO) Strategy for Multiscale Vasculature Fabrication

open access: yesAdvanced Materials, EarlyView.
A novel hydrogen bond re‐orientation (HyBRO) strategy enables three‐dimensional (3D) printing of vascular microchannel networks with high accuracy. By switching sacrificial material interactions with nonsolvents, HyBRO prevents swelling and deformation, enabling accurate hierarchical channels spanning a tenfold size range.
