RNA‐related functions of BRCA2 in transcription, replication, and genome stability

FEBS Letters, EarlyView.
Beyond its role in homologous recombination, BRCA2 regulates R‐loop homeostasis, DNA–RNA hybrid resolution, RNA polymerase II dynamics, and transcriptional activation. Disruption of any of these functions can contribute to genome instability, inflammatory signaling, and tumorigenesis. BRCA2 is a central tumor suppressor protein best known for its roles

Reactive/Adsorptive transport in (partially-) saturated porous media: from pore scale to core scale [PDF]

, 2011
Pore-scale modeling provides opportunities to study transport phenomena in fundamental ways because detailed information is available at the microscopic pore scale. This offers the best hope for bridging the traditional gap that exists between pore scale

Development and implementation of a dual-porosity pore network structure using X-ray computed tomography for pore network modeling purposes [PDF]

, 2011
3-D pore network modeling based on high-resolution X-ray computed tomography (XCT) is a useful tool for simulating pore-scale processes and phenomena within porous media in fields such as chemical and petroleum engineering and groundwater hydrology.

An Effective Method for Digital Rock Reconstruction with Enhanced Pore Connectivity

Applied Sciences
Digital rock technology is essential for characterizing the petrophysical properties of tight reservoirs. However, conventional construction methods often yield models with insufficient pore connectivity due to low porosity and complex nanopore ...

Artificial molecular machines and motors—Design and control of nanoscale motion

FEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Pore-scale modeling of unsaturated soil flow properties for Haplic Greyzem samples using single-scale XCT images

Soil Advances
Relative unsaturated hydraulic conductivity (Krw) and water retention are key soil hydraulic properties that control water and solute transport. Typically, Krw is predicted from the water retention curve (WRC) using models such as van Genuchten–Mualem ...

A context‐dependent modulatory role for eIF6 in acquired resistance to vemurafenib in melanoma

FEBS Letters, EarlyView.
Acquired resistance to vemurafenib upregulates the translation factor eIF6 in melanoma cells. Silencing eIF6 in resistant cells reduces proliferation and partially restores drug sensitivity, whereas its overexpression increases sensitivity across melanoma lines regardless of BRAF status, via modulation of mTOR, S6K, and MAPK signaling.

Pore Network Modeling of Tight Gas Formations

, 2016
Replicating pore topology/structure of tight gas reservoirs is essential for modeling fluid flow through such porous media. Constitutive relationships between the macroscopic properties of the medium can often help with such modeling efforts.
