Blood oxygen depletion is independent of dive function in a deep diving vertebrate, the northern elephant seal. [PDF]

open access: yesPLoS ONE, 2013
Although energetics is fundamental to animal ecology, traditional methods of determining metabolic rate are neither direct nor instantaneous. Recently, continuous blood oxygen (O2) measurements were used to assess energy expenditure in diving elephant ...

Une mer vraiment dyonisiaque

open access: yesPallas, 2009
Several studies have recently advanced our knowledge of the relations between Dionysos and the sea, often placed under the sign of the « winy sea » (oinos pontos) or of the « dionysiac sea ».

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

open access: yesFEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Extracellular vesicle lipidomics liquid biopsy reveals systemic and tumor microenvironment metabolic reprogramming in ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Extracellular vesicle (EV) lipidomic profiling of plasma and ascites from patients with high‐grade serous ovarian cancer and of ovarian cancer cell lines reveals enrichment of triglycerides (TGs), diacylglycerols (DGs), phosphatidylcholine (PCs), sphingomyelins (SMs), reflecting tumor metabolic reprogramming.

Diving and Pregnancy [PDF]

open access: yesJournal of Travel Medicine, 1994
Caroline Fife points out in her article in this issue of theJournal of Travel Medicine that 30% of today’s divers in the US, who dive for sport, are female. Though few research studies and surveys exist on the topic of pregnancy and hyperbaric exposure, meager gleanings do point to the opinion that pregnancy should contraindicate diving. Dr.

A new flow chip in combination with multiphoton microscopy as a protocol for longitudinal 3D imaging of tissue calcification under shear stress

open access: yesFEBS Open Bio, EarlyView.
Miniaturized flow chip platform enabling continuous perfusion and longitudinal multiphoton 3D imaging of vascular smooth muscle cell constructs under physiological flow. Brightfield imaging guides region selection, while CellTracker Green and mRuby‐labeled fetuin‐A visualize cells and mineral deposition, respectively. Magnesium supplementation markedly
