Introduction: The presence of a Lisfranc injury alone is considered a surgical indication in most patients. Indications for primary arthrodesis (PA) versus open reduction internal fixation (ORIF), however, is a topic of debate among surgeons. Conflicting data exists as to which treatment modality leads to improved patient-reported outcome measures (PROMs), reoperations, and complications.

Article Synopsis
  • The End-Triassic Extinction (~200 million years ago) was marked by a series of significant biotic extinctions and disruptions in the global carbon cycle, likely triggered by intense volcanic activity.
  • As volcanic eruptions increased CO levels in the atmosphere and oceans, this led to global warming and accelerated chemical weathering, resulting in more nutrients being released into the oceans, boosting biological productivity.
  • However, this productivity shift caused a decrease in oxygen levels in marine waters, resulting in dysoxia/anoxia and contributing to widespread extinctions in various fossil groups like bivalves, ammonoids, and radiolarians.

Objective: A buildup of skeletal muscle plasma membrane (PM) cholesterol content in mice occurs within 1 week of a Western-style high-fat diet and causes insulin resistance. The mechanism driving this cholesterol accumulation and insulin resistance is not known. Promising cell data implicate that the hexosamine biosynthesis pathway (HBP) triggers a cholesterolgenic response via increasing the transcriptional activity of Sp1.

The Lance Creek Formation (Late Cretaceous) is significant in the study of late dinosaurs and is a diverse formation containing both terrestrial and aquatic macrofossils. To study this important ecosystem, all of the fossils present must be uncovered and examined from Lance Creek sedimentary rocks, which exhibit variable degrees of lithification. In order to liberate the fossils, a dissolution methodology was designed to determine which solution was most effective at uncovering specimens and dissolving/disaggregating sediment.

Skeletal muscle insulin resistance manifests shortly after high-fat feeding, yet mechanisms are not known. Here we set out to determine whether excess skeletal muscle membrane cholesterol and cytoskeletal derangement known to compromise glucose transporter (GLUT)4 regulation occurs early after high-fat feeding. We fed 6-wk-old male C57BL/6NJ mice either a low-fat (LF, 10% kcal) or a high-fat (HF, 45% kcal) diet for 1 wk.
