Microfluidic study in a meter-long reactive path reveals how the medium’s structural heterogeneity shapes MICP-induced biocementation

open access: yesScientific Reports, 2022
Microbially induced calcium carbonate (CaCO3) precipitation (MICP) is one of the major sustainable alternatives to the artificial cementation of granular media.

Physically consistent simulation of transport of inertial particles in porous media [PDF]

open access: yes, 2011
A new numerical approach is presented for simulating the movement of test particles suspended in an incompressible fluid flowing through a porous matrix.

Potential therapeutic targeting of BKCa channels in glioblastoma treatment

open access: yesMolecular Oncology, EarlyView.
This review summarizes current insights into the role of BKCa and mitoBKCa channels in glioblastoma biology, their potential classification as oncochannels, and the emerging pharmacological strategies targeting these channels, emphasizing the translational challenges in developing BKCa‐directed therapies for glioblastoma treatment.

Chains in critical fluids and nanopores

open access: yes, 2004
The conformational behavior of a polymer in a critical binary solvent confined in a porous medium is studied. The size of the polymer in bulk, which is mainly governed by the correlation length of the solvent density fluctuations, depends on the ...

Therapeutic strategies for MMAE‐resistant bladder cancer through DPP4 inhibition

open access: yesMolecular Oncology, EarlyView.
We established monomethyl auristatin E (MMAE)‐resistant bladder cancer (BC) cell lines by exposure to progressively increasing concentrations of MMAE in vitro. RNA sequencing showed DPP4 expression was increased in MMAE‐resistant BC cells. Both si‐DPP4 and the DPP4 inhibitor sitagliptin suppressed the viability of MMAE‐resistant BC cells.

Modeling and Asymptotic Analysis of Combustion of Solid Fuel Deposited over an Inert Porous Medium

open access: yesJournal of Thermal Science and Technology, 2012
A simple mathematical model has been proposed for combustion of solid fuel deposited over an inert porous medium. The thermal nonequilibrium between the porous medium and gas is incorporated in the model considering two energy equations with different ...

RIPK4 function interferes with melanoma cell adhesion and metastasis

open access: yesMolecular Oncology, EarlyView.
RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.

Extremal geometry of a Brownian porous medium

open access: yes, 2013
The path W[0,t] of a Brownian motion on a d-dimensional torus T^d run for time t is a random compact subset of T^d. We study the geometric properties of the complement T^d \ W[0,t] for t large and d >= 3.

Three-dimensional auxetic porous medium

open access: yesMechanics of Materials, 2022
Abstract We propose the design of a novel three-dimensional porous continuous solid exhibiting negative Poisson’s ratio. The shape and periodic distribution of the pores guarantee cubic symmetry, and the directional dependence of the Poisson’s ratio and Young’s modulus shows a moderate degree of anisotropy and multidirectional auxeticity.

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

open access: yesMolecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.
