Quiz Yourself to Grow What You Know About Regeneration

Regeneration is the natural process of replacing or restoring cells that have been lost or damaged due to injury or disease. A few animals can regrow entire organs or other body parts, but most have limited abilities to regenerate. Scientists in the field of regenerative medicine study how some animals are able to rebuild lost body parts. By better understanding these processes and learning how to control them, researchers hope to develop new methods to treat injuries and diseases in people. Take this quiz to test what you know about regeneration and regenerative medicine. Then check out our Regeneration fact sheet and the regeneration issue of Pathways , a teaching resource produced in collaboration with Scholastic. 1.) Which of these animals don’t have the ability to regenerate? a.) Zebrafish Credit: iStock. Zebrafish can regrow their fins. They can also repair damaged organs, including the brain and heart, as well as an injured spinal cord. Try a different answer. b.) Fruit flies Credit: iStock. *That’s right! Fruit flies (Drosophila) can’t regrow lost or damaged body parts. They are a popular research organism for studying various aspects of developmental biology and genetics in the lab, but not for studying regeneration. c.) Sea urchins Credit: iStock. Sea urchins have the ability to regenerate damaged parts, including their spines and tube feet, even w...

Abstract PURPOSE: To evaluate the local effect of simvastatin (SVT) combined with deproteinized bovine bone (DBB) with hydroxyapatite/β-tricalcium phosphate biphasic ceramics (HA/TCP) and with collagen sponge (CS) on bone repair in critical size defects (CSDs) in rat calvaria. METHODS: Forty-two 5-mm diameter CSDs were made bilaterally in the calvaria of 18 rats. The animals were allocated according to the type of biomaterial and associations used to fill the CSD. After 8 weeks, the animals were euthanized, and their calvaria were evaluated for repaired tissue composition using histologic and histometric...

Abstract The heterogeneity of macrophages promotes renal fibrosis and plays an important role in the repair of kidney damage. The "microinflammation state" is closely related to accelerated mortality in patients with chronic kidney disease (CKD). The aim of this study was to investigate the relationship between microinflammation and macrophage polarization in CKD. The levels of high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) in peripheral blood of 30 non-dialysis CKD-5 patients (CKD group) and 20 healthy subjects (Con group) were measure...

For those who haven't been reading for a long time, I live in a rural part of Connecticut and ordinarily commute to work in Providence. The university has been closed for two weeks and I've been working remotely, but I had to go to the office yesterday to get some files off of my personal computer. You don't notice that things are very different out here in the boondocks, but it was very strange to see the downtown of Providence largely deserted.Notably, however, Rhode Island has so far had few confirmed cases of Covid -- 203 -- and only 28 people hospitalized. As far as I know there have been no deaths yet, although 11 pe...

RARITAN, NJ, March 28, 2020 – The Janssen Pharmaceutical Companies of Johnson &Johnson today announced the VOYAGER PAD study met its primary efficacy and principal safety endpoints, demonstrating the XARELTO® (rivaroxaban) vascular dose (2.5 mg twice daily) plus aspirin (100 mg once daily) was superior to aspirin alone in reducing the risk of major adverse limb and cardiovascular (CV) events by 15 percent in patients with symptomatic peripheral artery disease (PAD) after lower-extremity revascularization, with similar rates of TIMI[1] major bleeding. VOYAGER PAD is the only study to show a significant benefit...
