Differential Scanning Calorimetry contribution to a better understanding of the aging of gelled waxy crude oils

Oil & Gas Science and Technology, 2019
Below Wax Appearance Temperature (WAT), waxy crystals appear within the crude oil and make it viscous with yield stress and shear thinning properties. Particular attention has been paid during the past works on different parameters such as temperature ...

Adipocyte‐Derived Leptolin Enhances Energy Expenditure and Prevents Obesity

Advanced Science, Volume 13, Issue 46, 17 August 2026.
We identified a novel adipokine, which we named leptolin. In humans, leptolin levels in white adipose tissue were positively correlated with exercise and negatively associated with body mass index. We observed elevated leptolin in serum from athletes and lower leptolin in serum from obese individuals.

Occurrence and Characterization of Paraffin Wax Formed in Developing Wells and Pipelines

Energies, 2019
Deposition and precipitation of paraffin wax in pipelines are major problems in the production, transfer, storage, and processing of crude oil. To prevent complete clogging, it is necessary to minimize and remove deposited wax in pipelines and tubing ...

Estrogen Receptor Beta Activation Coordinates Liver Lipid Remodeling and Metabolic Fluxes, Preventing Lipotoxicity

Comprehensive Physiology, Volume 16, Issue 4, August 2026.
ERβ activation restores glucose and lipid homeostasis by remodeling the hepatic lipidome. Mechanistically, it promotes complete fatty acid oxidation and decreases Acetyl‐CoA levels, leading to reduced ketogenesis and lipotoxicity, as demonstrated through in vivo and in vitro approaches.

Dual Action of Dipyridamole in Experimental Rheumatoid Arthritis: Suppression of Joint Inflammation and Upregulation of Muscle Anabolism via Adenosine and AMPK Pathways

Arthritis &Rheumatology, Volume 78, Issue 7, Page 1535-1553, July 2026.
Objective Rheumatoid sarcopenia, characterized by the progressive loss of skeletal muscle mass and function, is a frequent comorbidity in rheumatoid arthritis (RA), linked to prolonged, severe systemic inflammation. Purinergic signaling (adenosine, AMP, and ATP) plays a crucial role in inflammation, myogenesis, and muscle hypertrophy.

Wax removal using pipeline pigs [PDF]

, 2004
The deposition of paraffin wax solids in pipelines and risers represents a continuing challenge to flow assurance in offshore installations. Wax deposits reduce product throughput, requiring increased energy expenditure to re-establish flow levels.
