The Nature Explorers Lassen Volcanic Region Expedition Part 2 of 13

submitted by: thenatureexplorers

We travel to the Lassen Volcanic Region to explore this high subalpine montane region just below the tree line, made up of vast conifer forests and rocky outcroppings. Here we observed a huge array of butterflies, moths, bees, and other insects pollinating flowers to ensure their continued survival.

Absorption of Iron from Ferritin Is Independent of Heme Iron and Ferrous Salts in Women and Rat Intestinal Segments.

submitted by: egoldsmith
Ferritin iron from food is readily bioavailable to humans and has the potential for treating iron deficiency. Whether ferritin iron absorption is mechanistically different from iron absorption from small iron complexes/salts remains controversial. Here, we studied iron absorption (RBC 59Fe) from radiolabeled ferritin iron (0.5 mg) in healthy women with or without non-ferritin iron competitors, ferrous sulfate, or hemoglobin. A 9-fold excess of non-ferritin iron competitor had no significant...

Video tip of the week: OpenHelix App on SciVerse to Extend Research

submitted by: OpenHelix
See our blog post at URL http://blog.openhelix.com/?p=10810 for more information on this resource. In today’s tip I will introduce you to another one of our efforts to “extend research” by showing you a glimpse of an OpenHelix app that we designed for the SciVerse platform from Elsevier. This app scans a ScienceDirect journal article for any database names or URLs that we train on, and then displays a list of such resources in the window of the app.
