Performance comparison of novel chemical agents in improving oil recovery from tight sands through spontaneous imbibition

Petroleum Science, 2019
Tight sands are abundant in nanopores leading to a high capillary pressure and normally a low fluid injectivity. As such, spontaneous imbibition might be an effective mechanism for improving oil recovery from tight sands after fracturing.

PRMT1‐Mediated LDHA Methylation Drives STAT3 Lactylation to Orchestrate Intestinal Inflammation and Tumorigenesis

Advanced Science, EarlyView.
This study identifies an immunometabolic axis wherein SAM‐driven PRMT1 methylates LDHA, enhancing its activity. The resultant lactate induces STAT3 K709 lactylation, which stabilizes an active conformation to promote STAT3 phosphorylation and IL‐10 expression.

INVERSE MODELING OF SPONTANEOUS IMBIBITION

, 2023
Reservoirs that contain natural fracture systems, often developed through water injection, comprise a significant portion of the global oil supply. The injected fluid tends to flow preferentially through the fracture network, thereby bypassing the matrix

Polymer Matrix‐Based 3D Culture Significantly Enhances the Differentiation and Immunomodulatory Functions of Human Adipose‐Derived Stem Cells

Advanced Science, EarlyView.
The 3D culture of human adipose‐derived stem cells (hADSCs) on a crosslinked cyclosiloxane‐based poly‐Z matrix platform enables the formation of spheroid structures enriched with extracellular matrix (ECM). These ECM‐enriched hADSC spheroids cultured on poly‐Z exhibit enhanced differentiation potential, immunomodulatory capacity, and in vivo ...

Nigra‐Subthalamic Dopaminergic Circuitry Modulates and Represents Distinct Pain Modality in Physiological and Pain States in Mice

Advanced Science, EarlyView.
Nigral dopaminergic (DA) neurons modulate and represent pain with a preference to a particular modality (mechanical) and laterality (contralateral), which are controlled by nigral GABAergic neurons. The pain modulation is mimicked by the nigro‐subthalamic projection and its downstream neurons, involving D2‐like receptors.
