Amazing Organisms and the Lessons They Can Teach Us

What do you have in common with rodents, birds, and reptiles? A lot more than you might think. These creatures have organs and body systems very similar to our own: a skeleton, digestive tract, brain, nervous system, heart, network of blood vessels, and more. Even so-called “simple” organisms such as insects and worms use essentially the same genetic and molecular pathways we do. Studying these organisms provides a deeper understanding of human biology in health and disease, and makes possible new ways to prevent, diagnose, and treat a wide range of conditions. Historically, scientists have relied on a few key organisms, including bacteria, fruit flies, rats, and mice, to study the basic life processes that run bodily functions. In recent years, scientists have begun to add other organisms to their toolkits. Many of these newer research organisms are particularly well suited for a specific type of investigation. For example, the small, freshwater zebrafish grows quickly and has transparent embryos and see-through eggs, making it ideal for examining how organs develop. Organisms such as flatworms, salamanders, and sea urchins can regrow whole limbs, suggesting they hold clues about how to improve wound healing and tissue regeneration in humans. Here are profiles of other amazing organisms that are entering the research world. Australian Zebra Finch Credit: Chris Olson. Whether it’s a robin, sparrow, or yellow-rumped warbler, each son...

Publication date: Available online 16 June 2019Source: Pharmacological ResearchAuthor(s): Vasundhara Kain, Jeevan Kumar Jadapalli, Bochra Tourki, Ganesh V. HaladeAbstractLifestyle or age-related risk factors over-activate the inflammation that triggers acute heart failure (HF)-related mortality following myocardial infarction (MI). Post-MI activated leukocytes express formyl peptide receptor 2 (FPR2) that is essential for inflammation-resolution and in cardiac healing. However, the role of FPR2 in acute HF is incomplete and remain of interest. Here, we aimed to determine whether pharmacological inhibition of FPR2 perturb l...

Organic Herbal Supply, Inc. announced today that it is conducting a voluntary nationwide recall of all lots of Uproar, Cummor, Zrect, Monkey Business, Xrect, Rectalis, Tornado, Zdaily, BigNHard, Enhancerol Natural Male Enhancement capsules. FDA analysis has found the products to contain Tadalafil.  Tadalafil is a FDA-approved drug used as treatment for male Erectile Dysfunction (ED), the presence of tadalafil in these male enhancement products renders it an unapproved drug for which safety and efficacy have not been established and, therefore, subject to recall. Organic Herbal Supply is also recalling Zrect for Women ...

Abstract We hypothesize that, ancestrally, sex-specific immune modulation evolved to facilitate survival of the pregnant person in the presence of an invasive placenta and an immunologically challenging pregnancy - an idea we term the 'pregnancy compensation hypothesis' (PCH). Further, we propose that sex differences in immune function are mediated, at least in part, by the evolution of gene content and dosage on the sex chromosomes, and are regulated by reproductive hormones. Finally, we propose that changes in reproductive ecology in industrialized environments exacerbate these evolved sex differences, resulting...

AbstractSimulated workplace neutron fields of a\(^{241}\)Am –Be source moderated by polyethylene spheres have been developed. The characterization in terms of neutron fluence rate and neutron ambient dose equivalent rate,\(H^*(10)\), was performed using Bonner sphere spectrometer and the MAXED and FRUIT unfolding codes. The neutron fluence rates and the\(H^*(10)\) rates obtained from the two codes are in good agreement with the discrepancies of 8% and 6%, respectively. The neutron ambient dose equivalent-averaged energies and the neutron fluence-to-dose equivalent conversion coefficients were also evaluated in compar...
