Quantum effects in Acoustic Black Holes: the Backreaction [PDF]
, 2004 We investigate the backreaction equations for an acoustic black hole formed in a Laval nozzle under the assumption that the motion of the fluid is one-dimensional. The solution in the near-horizon region shows that as phonons are (thermally) radiated the

Estrogen Regulation of the human PEMT (phosphatidylethanolamine N‐methyltransferase) gene
The FASEB Journal, 2006 Choline is an essential nutrient for humans, though some part of this requirement can be met by endogenous synthesis catalyzed by phosphatidylethanolamine N‐methyltransferase (PEMT). Human diets which lack sufficient choline intake can result in organ and muscle dysfunction.

Daily rhythms of glycerophospholipid synthesis in fibroblast cultures involve differential enzyme contributions [PDF]
, 2013 Circadian clocks regulate the temporal organization of several biochemical processes including lipid metabolism and their disruption leads to severe metabolic disorders. Immortalized cell lines acting as circadian clocks display daily variations in [32P]-

Arsenite methyltransferase 3 is required for mitochondrial function and hepatic lipid metabolism
The FEBS Journal, EarlyView.AS3MT is a protein that helps the body process arsenic, a naturally occurring toxin found in water and soil. We discovered it also helps cells make and use energy properly. Without AS3MT, cells' mitochondria do not work well, leading to fatty liver and reduced activity. Increasing AS3MT in liver cells restores energy and protects against arsenic damage,

Northern cod (Gadus morhua) movement: insights from acoustic telemetry and genomics
Journal of Fish Biology, EarlyView.Abstract Knowledge of the timing and diversity of fish movements within a commercially exploited stock complex is required to ensure the sustainability of fisheries. Although migration can be driven by environmental factors, genomic mechanisms also play an important role in this complex life‐history trait. The northern cod (Gadus morhua) stock complex,

Sequential Wnt Agonist then Antagonist Treatment Accelerates Tissue Repair and Minimizes Fibrosis [PDF]
, 2019 Tissue fibrosis compromises organ function and occurs as a potential long-term outcome in response to acute tissue injuries. Currently, lack of mechanistic understanding prevents effective prevention and treatment of the progression from acute injury to ...

Thin-shell wormholes in dilaton gravity
, 2005 In this work we construct charged thin-shell Lorentzian wormholes in dilaton gravity. The exotic matter required for the construction is localized in the shell and the energy conditions are satisfied outside the shell.
