Characterizing Loss of Control Associated With Binge Eating in College-Age Men.

Background: The (5th ed.) identifies key features of binge eating (BE) to include the consumption of a large amount of food and the perception of loss of control (LOC) over eating during a distinct episode. While earlier research has focused on food consumption, findings are now emerging on the role of LOC associated with the BE episodes, particularly in women.

What Does an Insect Hear? Reassessing the Role of Hearing in Predator Avoidance with Insights from Vertebrate Prey.

Insects have a diversity of hearing organs known to function in a variety of contexts, including reproduction, locating food, and defense. While the role of hearing in predator avoidance has been extensively researched over the past several decades, this research has focused on the detection of one type of predator-echolocating bats. Here we reassess the role of hearing in antipredator defense by considering how insects use their ears to detect and avoid the wide range of predators that consume them.

Hypoxemia during hemodialysis: a critical review of the facts.

The literature describing the fall in PaO2 during dialysis is intensively and critically reviewed. This phenomenon is related to both the type of membrane used (cellulosic v noncellulosic membrane), and to the composition of the dialysate (acetate v bicarbonate). It appears that a ventilation/perfusion mismatch due to pulmonary leukostasis can, in part, explain hypoxemia in patients dialyzed with cellulosic membranes.

The acid-base status does not influence the rate of acetate metabolism in hemodialyzed patients.

The present study was undertaken to evaluate whether the acid-base status influences the rate of acetate metabolism in patients chronically hemodialyzed against acetate. Ten patients (5 "intolerant" and 5 "tolerant" to acetate) received in a randomized order and for three consecutive dialyses each of the six following infusions in the venous line of the dialyzer: NaHCO3 (22, 44 or 88 mEq/h), NaCl (22 or 44 mEq/h) or Dextrose 5% in water (30 mmol/h). Plasma acetate was measured at the end of the dialysis.
