Membranes on an Orbifold

open access: yesPhysical Review Letters, 2008
We harvest clues to aid with the interpretation of the recently discovered N=8 supersymmetric Chern-Simons theory with SO(4) gauge symmetry. The theory is argued to describe two membranes moving in the orbifold R8/Z2. At level k=1 and k=2, the classical moduli space M coincides with the infra-red moduli space of SO(4) and SO(5) super Yang-Mills theory ...

A histidine‐rich extension of the mitochondrial F0 subunit ATP6 from the ice worm Mesenchytraeus solifugus increases ATP synthase activity in bacteria

open access: yesFEBS Letters, EarlyView.
The glacier ice worm Mesenchytraeus solifugus survives year‐round at 0 °C. Its ATP6 subunit, which forms a regulatory component of the proton pore in mitochondrial ATP synthase, has a carboxy‐terminal extension not found in any other organism examined to date. Here, we show that fusion of this extension to the homologous AtpB protein in E. coli results

Improved electrochemical conversion of CO2 to multicarbon products by using molecular doping

open access: yesNature Communications, 2021
Strategies to systematically tune CO2 electroreduction to multicarbon products are of high interests. Here the authors report electron withdrawing functional group alters the reaction pathway towards C2+ products by adjusting the oxidation state of ...

Membrane biology: Membrane-regulated transcription [PDF]

open access: yesCurrent Biology, 2000
The activation of membrane-bound transcription factors involves release from the membrane by proteolysis. Recent studies show that, for some proteins, cleavage is performed by the proteasome, whereas others require specific proteases.

Ablation of LRP6 in alpha‐smooth muscle actin‐expressing cells abrogates lung inflammation and fibrosis upon bleomycin‐induced lung injury

open access: yesFEBS Letters, EarlyView.
Low‐density lipoprotein receptor‐related protein 6 (LRP6) is a key receptor for the Wnt antagonist Dickkopf1 (DKK1). DKK1 protein expression is induced in a bleomycin (BLM)‐induced lung injury model. We show that DKK1 induces proinflammatory and profibrotic genes in lung fibroblasts.

Dielectric Properties of Polysulfone Carbon Nanotube Composite Membranes [PDF]

open access: yesarXiv, 2022
Polymeric membranes, including Polysulfone (PSf) membranes, are routinely used for water treatment. To enhance water permeation of above membranes, it is common to synthesize polymeric membranes with carbon nanotubes (CNTs) embedded in them. It is seen that water permeability of membranes having vertically aligned CNTs is higher, as compared to those ...

Adhesion-Induced Lateral Phase Separation in Membranes [PDF]

open access: yesEur. Phys. J. E 3, 259 (2000), 2000
Adhesion between membranes is studied using a phenomenological model, where the inter-membrane distance is coupled to the concentration of sticker molecules on the membranes. The model applies to both for adhesion of two flexible membranes and to adhesion of one flexible membrane onto a second membrane supported on a solid substrate. We mainly consider

Characteristics of the Kelch domain containing (KLHDC) subfamily and relationships with diseases

open access: yesFEBS Letters, EarlyView.
The Kelch protein superfamily includes 63 members, with the KLHDC subfamily having 10 proteins. While their functions are not fully understood, recent advances in KLHDC2's structure and role in protein degradation have highlighted its potential for drug development, especially in PROTAC therapies.

Experimental Mixed-Gas Permeability, Sorption and Diffusion of CO2-CH4 Mixtures in 6FDA-mPDA Polyimide Membrane: Unveiling the Effect of Competitive Sorption on Permeability Selectivity

open access: yesMembranes, 2019
The nonideal behavior of polymeric membranes during separation of gas mixtures can be quantified via the solution-diffusion theory from experimental mixed-gas solubility and permeability coefficients.

Constructing rapid water vapor transport channels within mixed matrix membranes based on two-dimensional mesoporous nanosheets

open access: yesCommunications Chemistry, 2022
Gas dehumidification with permeable membranes is typically a technique low in operating costs and environmental impact, making it preferable over condensation or adsorption methods, but membrane permeability and selectivity remain a trade-off.
