Evaluation of Emulsified Acrylate Polymer and its Pour Point Depressant Performance [PDF]

, 2016
A traditional pour point depressant (PPD) of acrylate polymer is in solid form at room temperature. The costing for preheating and dilution is a prerequisite to be considered for its utilization in a crude oil industry.

Effectiveness of Resistance Intradialytic Exercise Compared to Aerobic Intradialytic Exercise for Patients With Chronic Kidney Disease: A Randomized Controlled Clinical Trial

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Patients with chronic kidney disease undergoing hemodialysis commonly experience reduced physical function, fatigue, poor sleep quality, and impaired health‐related quality of life. Intradialytic exercise has been proposed as a non‐pharmacological strategy to improve these outcomes.

Structure‐forward targeting of claudins with synthetic binders

FEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

A regular, hydrophobically modified polyampholyte as novel pour point depressant

, 2005
A new regular polyampholyte, namely poly(N,N-diallyl-N-octadecylamine-alt-(maleic acid)), was studied as an additive to crude oil. The amphiphilic polyampholyte proved to be an efficient pour point depressant, to inhibit the deposition of wax, and to ...

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Castration‐resistant prostate cancer cells are addicted to the high activity of cyclin‐dependent kinase 2

Molecular Oncology, EarlyView.
We show that emergence of castration‐resistant prostate (CRPC) is associated with significant upregulation of cyclins that positively regulate cyclin‐dependent kinase 2 (CDK2) and concomitant downregulation of CDK4 cyclins. This renders CRPC cells dependent on the high activity of CDK2, and CDK2 inhibitors synergistically sensitize CRPC cells to both ...

Covalently Grafted Graphene Oxide/Poly(C_n‑acrylate) Nanocomposites by Surface-Initiated ATRP: An Efficient Antifriction, Antiwear, and Pour-Point-Depressant Lubricating Additive in Oil Media

, 2016
Nanocomposites of graphene oxide with polyacrylates with varying numbers of carbon atoms from 10 to 18 were prepared by surface-initiated atom-transfer radical polymerization (SI-ATRP), thereby controlling the density of polymer grafting through ...
