Influence of Clay Wettability Alteration on Relative Permeability

Geophysical Research Letters, 2020
Understanding the wettability of porous materials is important to model fluid flow in the subsurface. One of the critical factors that influences wetting in real reservoirs is the composition of geologic materials.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

EFFECT OF NON-EQUILIBRIUM RELATIVE PERMEABILITY ON WELL PERFORMANCE

Известия высших учебных заведений: Нефть и газ, 2018
The article discusses the results of applying the developed software for numerical analysis of the effectiveness of oil well work. We have studied the object which is similar to BV8(1-2) formation of the Samotlor oil field in its geology and geological ...

Capacity investigation of brine-bearing sands of the Frio Formation for geologic sequestration of CO2 [PDF]

, 2001
The capacity of fluvial brine-bearing formations to sequester CO2 is investigated using numerical simulations of CO2 injection and storage. Capacity is defined as the volume fraction of the subsurface available for CO2 storage and is conceptualized as a ...

Mechanisms of IgE‐mediated food allergy and the role of allergen‐specific B cells

FEBS Letters, EarlyView.
Food allergy arises when allergen‐specific B cells preferentially produce immunoglobulin E (IgE) antibodies against harmless foods. This article explains the mechanisms driving IgE‐mediated reactions, highlights the central role of these B cells, and discusses how natural tolerance (NT) and oral immunotherapy (OIT) can reshape allergic immune responses.

Size-Dependent Bruggeman Approach for Dielectric-Magnetic Composite Materials

, 2004
Expressions arising from the Bruggeman approach for the homogenization of dielectric-magnetic composite materials, without ignoring the sizes of the spherical particles, are presented. These expressions exhibit the proper limit behavior.

Fractal characteristics of unsaturated sands − implications to relative permeability in hydrate-bearing sediments

Journal of Natural Gas Science and Engineering, 2019
Precise estimation of gas production from hydrate deposits heavily relies on an accurate description of relative permeability to water and gas in hydrate-bearing sediments. Relative permeability innately depicts the competing flow of gas and water phases

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Aggressive prostate cancer is associated with pericyte dysfunction

Molecular Oncology, EarlyView.
Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).
