On the Structure and Mechanism of Two-Pore Channels [PDF]
The FEBS Journal, 2017 AbstractIn eukaryotes, two-pore channels (TPC1-3) comprise a family of ion channels that regulate the conductance of Na+and Ca2+ions across cellular membranes. TPC1-3 form endolysosomal channels, but TPC3 can also function in the plasma membrane. TPC1/3 are voltage-gated channels, but TPC2 opens in response to binding endolysosome-specific lipid ...

Exploration of Kastification and Characterization Based on Borehole Image
Applied Sciences, 2022 The characteristics of the karst pore structure not only affect the seepage features of the rock mass in the karst area but also have a noticeable effect on the mechanical behavior in the process of rock mass loading.

Effect of sintering atmosphere on the pore-structure stability of cerium-doped nanostructured alumina [PDF]
, 1994 Pore-structure stability of pure and Ce-doped alumina in air and argon atmospheres was studied using DTA, TGA, N2 ads./des. and XRD with a view to understand the importance of the ionic size of the dopant cation on the pore-structure stability of alumina.

Structure and assembly of a bacterial gasdermin pore
Nature, 2023 AbstractIn response to pathogen infection, gasdermin (GSDM) proteins form membrane pores that induce a host cell death process called pyroptosis1–3. Studies of human and mouse GSDM pores reveal the functions and architectures of 24–33 protomers assemblies4–9, but the mechanism and evolutionary origin of membrane targeting and GSDM pore formation remain

Energy Reports, 2022 The pore structure controls the storage and migration of geofluids within shale and ultimately determines its reservoir quality. Therefore, the characterization of shale pore structure has become more and more meaningful in geological engineering ...

Structure of the CLC-1 chloride channel from Homo sapiens. [PDF]
, 2018 CLC channels mediate passive Cl- conduction, while CLC transporters mediate active Cl- transport coupled to H+ transport in the opposite direction. The distinction between CLC-0/1/2 channels and CLC transporters seems undetectable by amino acid sequence.

Pore Structure Changes Occur During CO2 Injection into Carbonate Reservoirs
Scientific Reports, 2020 Observations and modeling studies have shown that during CO2 injection into underground carbonate reservoirs, the dissolution of CO2 into formation water forms acidic brine, leading to fluid-rock interactions that can significantly impact the hydraulic ...

Structure and gating of the nuclear pore complex [PDF]
Nature Communications, 2015 AbstractNuclear pore complexes (NPCs) perforate the nuclear envelope and allow the exchange of macromolecules between the nucleus and the cytoplasm. To acquire a deeper understanding of this transport mechanism, we analyse the structure of the NPC scaffold and permeability barrier, by reconstructing the Xenopus laevis oocyte NPC from native nuclear ...
