Influence of Supercritical CO2 on the Formation Sensitivity of Tight Sandstone

Frontiers in Energy Research, 2022
It is challenging to get water-based fracture fluid to flow back into low-pressure gas reservoirs. In order to solve the problem, supercritical CO2 is a novel type of non-aqueous fracturing technique with a wide range of applications prospect in low ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

FEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

EVALUATION OF THE STATE OF THE REPAIRED WELL NEAR BOTTOMHOLE ZONE BY SKIN-FACTOR

Известия высших учебных заведений: Нефть и газ, 2015
This article object of study is a bottomhole zone of exploration wells or repaired wells with positive values of skin-factor. The skin-factor is usually determined at processing of data of hydrodynamic studies of wells under unsteady-state conditions by ...

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

FEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

DISTINCTIVE FEATURES OF HYDRODYNAMIC INVESTIGATION OF GAS-CONDENSATE WELLS

Известия высших учебных заведений: Нефть и газ, 2015
An equation is proposed for constructing a theoretical pressure build-up curve, which takes into account the effect of the well storage capacity, skin effect and presence of condensate in the bottomhole zone.

Evaluating the effect of γ‐oryzanol on MASLD pathology using a medaka fish model

FEBS Open Bio, EarlyView.
This study explores a liver disease called MASLD, which is increasing worldwide and can lead to serious damage. Researchers used medaka fish instead of rodents to test a food compound, γ‐oryzanol. Fish fed this compound had less liver fat and healthier gut bacteria.
